Summary of the invention

Technical problem

However, in the related art mounting and dismounting device disclosed in EP 2324 745 A, when removing the toilet seat / toilet lid unit from the toilet bowl, an unlocking operation is required to insert the hand into a position inside the toilet seat / toilet lid unit and push the pressure member against the biasing force of the spring member. The toilet seat / toilet lid unit is mounted on the toilet bowl by the mounting and demounting devices provided at two locations, and therefore, this unlocking operation of pushing the pressure member needs to be performed simultaneously at the respective mounting and demounting devices that configure two hinge devices with both hands. Therefore, in the related art mounting and dismounting device and the mounting device hinge using the mounting and dismounting devices, an operation of removing the toilet seat unit / toilet lid from the toilet bowl is cumbersome and difficult. For this reason, in the related art, the cleaning or maintenance of a western-style toilet, or the job of replacing a toilet seat / toilet lid unit is not easily done. Additionally, in addition to the western-style toilet, in other devices having a structure in which an object on one side is removably mounted on an object on the other side, using the mounting and dismounting device having said configuration and the hinge device using the mounting and demounting device, the same problem also occurs.

Solution to the problem

The present invention has been made to solve such problems and provides a mounting and demounting device for removably mounting an object on one side, on an object on the other side by mounting the object on one side, on the object on the other side. by coupling between the object on one side and the object on the other side and separating the object on one side from the object on the other side by releasing the coupling between the object on one side and the object on the other side, including the device:

a shaft having a first shaft part with a fixing groove formed therein, and a second shaft part having a larger diameter than the first shaft part, and in which one end on the side of the second shaft tree can be mounted on the side of the object on one side;

a housing that has a first space in front of an end face and can be mounted on the side of the object on the other side;

a fixed member having a first insertion opening formed in an end face with a diameter to allow insertion of the first shaft part and the second shaft part, a second space communicating with the first insertion opening, a plurality of guide grooves formed in an inner periphery surrounding the second space along an insertion direction of the shaft through the first insertion opening, and a guide wall that is formed by making a wall surface of the inner periphery protrudes from a terminal end of the guide groove on the other end face side facing the second space, and whose protruding height gradually decreases towards the neighboring guide groove, the fixed member being housed in and fixed to the first space with the first insertion opening exposed;

a pair of slide members, each slide member having a wrapping portion that can engage the locking groove to wrap around the shaft, and a slide guide portion formed to be continuous with the wrapping portion;

a linear motion member having a second insert opening that is formed in an end face with a diameter into which the first shaft part is inserted and the second shaft part is not inserted, and is arranged to be continuous with the first insertion opening when the linear movement member is housed in the second space, a third space that communicates with the second insertion opening, a first guided strip that is formed to protrude at an outer periphery and conforms to a of the guide grooves, the other end face which is formed in the shape of a mountain with an end face part in a formation direction of the first guided strip guided as an upper part and towards which the third space is oriented, and a slide groove formed to communicate with the second insertion opening in order to slidably hold the slide guide portion in a direction orthogonal to the insertion direction of the shaft bowl, the linear moving member being housed in the second space so that it can move linearly in the insertion direction of the shaft while the first guided strip is guided by one of the guide grooves;

a rotating member having a control part that is rotatable, and when the control part is rotating, it comes into contact with the enclosing part and thus making the slide member with the slide guide part held in the sliding groove is sliding in a direction towards an axial center and causing the wrapping part to engage with the fixing groove formed in the first inserted shaft part, a small diameter part which is formed with the control part and fits to the third space, a second guided strip having a sloped end face that is pushed over the top of the mountain-shaped shape formed on the other end face of the linear motion member beyond the projecting height of the wall guide to deviate from the guide groove, thereby contacting an inclined end of the mountain-shaped shape formed on the other end face of the movement member. to linear and a protruding end of the guide wall, and fits into the guide groove by a predetermined length, a large diameter part with the second guided strip formed to protrude at an outer periphery, and an insert hole which is arranged to be continuous with the second insertion opening when the small diameter part is attached to the third space, and has a diameter to allow insertion of the first shaft part, and wherein the large diameter part is housed in the second space in order to be able to move linearly in a predetermined length in the insertion direction of the shaft while the second guided strip is guided in a predetermined length by the guide groove; and

an elastic member that biases the linear movement member and the rotation member to the side of the fixed member attached to the housing.

The mounting and demounting device in this configuration is configured with the shaft having one end that is mounted on the side of the object on one side, and the housing that is mounted on the side of the object on the other side. The fixed member is fixed to the first space inside the housing, and the linear movement member and the rotation member are housed in the second space inside the fixed member with the first and second insertion openings and the insert hole communicating with each other. The small diameter portion of the rotation member fits into the third space inside the linear motion member housed in the second space. The elastic member urges the rotation member and the linear motion member to the side of the fixed member.

Mounting the object on one side, on the object on the other side is done by grasping the object on one side or the object on the other side, inserting the other end of the shaft mounted on the object on one side into the first insertion opening of the fixed member fixed to the housing mounted on the object on the other side, and pressing the object on one side or the object on the other side against the object on the other side or the object on one side. The other end of the shaft inserted into the first insertion opening of the fixed member passes through the first insertion opening. However, the second shaft part cannot pass through the second insertion opening formed in the linear movement member, such that the second shaft part pushes the linear movement member by a force that presses the object in one side or the object on the other side against the object on the other side or the object on one side. With the pressing force, the linear moving member moves linearly to the other end face side of the housing against the biasing force of the elastic member, while the first guided strip formed on the outer periphery is guided by one of the guide grooves provided in the fixed member.

With the linear movement of the linear movement member, the rotating member moves linearly together with the linear movement member towards the other end face side of the housing against the biasing force of the elastic member while pushing the end face slant of the second guided strip on top of the mountain shape formed on the other end face of the linear motion member and the second guided strip is guided by one of the guide grooves provided in the fixed member. At this time, the second guided strip is fixed to one of the guide grooves only by a predetermined length and therefore if the rotating member moves linearly when pushed past the projecting height of the guide wall provided in the fixed member, the second guided strip deviates from the guide groove. If the second guided strip deviates from the guide groove, the rotation member becomes rotatable around the axial center thereof while being guided through the third space of the linear movement member, to which the small diameter part is attached. For this reason, the inclined end face of the second guided strip slides upward on the inclined surface of the other mountain-shaped end face of the linear motion member, such that the rotation member rotates with the other. inclined end face of the linear motion member as a raceway surface.

Subsequently, if the force pressing the object on one side or the object on the other side against the object on the other side or the object on one side becomes equal to or less than the pushing force of the elastic member, the rotating member it is pushed back towards the end face side of the housing as it is pushed by the elastic member. If the rotating member is pushed back, the sloped end face of the second guided strip contacts the projecting end of the guide wall provided to project towards the other end face side of the fixed member.

The protruding height of the guide wall gradually decreases towards the neighboring guide groove, and therefore, the rotating member is pushed back towards the end face side of the casing which is pushed by the elastic member, thereby that the rotating member rotates further while the sloping end face of the second guided strip is guided by the projecting end of the guide wall. With this rotation, the control piece which is formed in the small diameter part of the rotation member and exists in the third space of the linear motion member also rotates. The slide guide portions of the slide members are slidably held in the slide grooves of the linear motion member, and the rotary control part comes into contact with the envelope portion of the slide member, thereby sliding the slide members along the slide grooves in a direction toward the axial center of the linear motion member.

If the rotation member rotates in such a way that the inclined end face of the second guided strip reaches the neighboring guide groove, the wrapping part of the sliding member engages the fixing groove formed in the first shaft part of the shaft. inserted into the first and second insertion openings and the insertion hole. The wrapping part of the slide member engages the shaft fixing groove, whereby the shaft does not come out of the housing and a locked state is created where the object on one side is mounted and fixed to the object on the other side . If the inclined end face of the second guided strip reaches the neighboring guide groove, the second guided strip is pushed back by being pushed by the elastic member and returns to the initial state where it is fixed to the neighboring guide groove by a predetermined length .

Also, the withdrawal of the object on one side of the object on the other side is done by pressing the object on one side or the object on the other side against the object on the other side or the object on one side again. With the pressing force, the linear movement member is pushed by the second shaft part of the shaft and moves linearly back to the other side of the end face of the housing against the biasing force of the elastic member while the first Guided strip is guided by the guide groove. With the linear movement of the linear movement member, the rotation member also moves linearly back to the other side of the end face of the housing together with the linear movement member against the biasing force of the elastic member. If the rotating member moves linearly when pushed past the projecting height of the guide wall provided on the fixed member, the second guided strip is again deflected from the guide groove.

If the second guided strip deviates from the guide groove, the rotation member rotates again around the axial center thereof while being guided through the third space into which the small diameter portion fits. For this reason, the rotation member rotates with the other inclined end face of the linear motion member as a raceway surface. Subsequently, if the force pressing the object on one side or the object on the other side against the object on the other side or the object on one side again becomes equal to or less than the pushing force of the elastic member, the The rotation is pushed back toward the end face side of the housing by being pushed by the elastic member, and the sloping end face of the second guided strip comes into contact with the projecting end of the guide wall. Therefore, the rotation member rotates again while the sloping end face of the second guided strip is guided by the projecting end of the guide wall.

With this rotation, the control part formed in the small diameter part of the rotating member also rotates, and the control part moves from a rotational position where the control part comes into contact with the enclosing part, making this so that the wrapping part engages with the fixing groove. Therefore, the slide members become slidable in a direction away from the axial center, in which the wrapping part separates from the fixing groove, and an unlocked state is created where it is possible to remove the shaft from the housing. If the rotating member rotates again, such that the inclined end face of the second guided strip reaches the neighboring guide groove, the second guided strip is pushed back by being pushed by the elastic member and returns to the state again. initial where it is fixed to the neighboring guide groove at a predetermined length.

Therefore, according to the mounting and dismounting device having this configuration, mounting of the object on one side, on the object on the other side, and removal of the object on one side of the object on the other side are simply performed pressing the object on one side or the object on the other side against the object on the other side or the object on one side. For this reason, it is possible to easily remove the toilet seat / toilet lid unit from the toilet bowl without performing a cumbersome and difficult operation in which an unlocking operation is performed by pushing a pressing member simultaneously with both hands with respect to the respective mounting and dismounting devices that make up two hinge devices, as in the related art mounting and dismounting device, which is used for a western style toilet. Therefore, it is possible to easily carry out the cleaning or maintenance of the western-style toilet, or the job of replacing the toilet seat unit / toilet lid. In addition, the mounting and dismounting device having this configuration is not limited to a mounting and dismounting device that is used for the western-style toilet, and it can also be applied to other mounting and dismounting devices, and the same operation is shown. and effects.

Furthermore, in the mounting and demounting device according to the present invention, the guide grooves are provided at four locations at equal intervals around an axial center of the fixed member, the first guided strips and the tops of the shaped shapes Coaster formed on the other end face of the linear motion member are provided at four locations at equal intervals around an axial center of the linear motion member, and the second guided strips are provided at four locations at equal intervals around a center. rotation member axial.

According to this configuration, the linear motion member is guided with the first guided strips provided at four locations at equal intervals around the axial center thereof attached to guide grooves provided at four locations at equal intervals around the axial center of the member. fixed, and therefore the linear motion member moves stably and linearly. The rotation member is guided by the four guide grooves because the inclined end faces of the second guide strips provided at four locations at equal intervals around the axial center thereof are pushed by the tops of the shaped shapes. coaster provided at four locations at equal intervals on the other end face of the linear motion member, whereby the rotation member moves in a stable and linear manner together with the linear motion member. Furthermore, the rotation of the rotation member is accomplished by the respective second guided strips deviating from the guide grooves. The deviation of the respective second guided strips from the guide grooves is performed each time the rotation member rotates one quarter, and therefore the locked state and the unlocked state of the shaft appear alternately.

Furthermore, in the mounting and dismounting device according to the present invention, a pair of slide grooves are provided at two locations facing each other with an opening center of the second insertion opening interposed therebetween, the member The slide is configured by a pair of slide members formed symmetrically with respect to the opening center of the second insertion opening and arranged symmetrically in the respective slide grooves, and a pair of control pieces are provided to be spaced apart from each other. a distance for holding the pair of housing parts fixed to the fixing slot, at two locations facing each other with an axial center of the rotating member interposed therebetween.

In accordance with this configuration, the respective slide guide portions of the pair of slide members are slidably held in the pair of slide grooves provided at two locations facing each other with the opening center of the second opening. insertion of the linear movement member interposed between them. Therefore, the pair of slide members are held such that they can slide in a direction in which the respective wrapping parts are reciprocally directed towards the axial center of the linear movement member, and in an opposite direction in which the respective wrapping parts are reciprocally separated from the axial center of the movement member linear. The rotation member rotates a quarter turn, such that the control pieces provided at two locations facing each other with the axial center of the rotation member interposed between them come into contact with the respective housing parts of the pair of slide members, whereby the respective wrapping parts slide in the direction toward the axial center of the linear motion member. With this sliding, the respective wrapping parts engage with the fixing groove of the shaft inserted in the first and second insertion openings and the insertion hole in a way to interpose the fixing groove between them, and thus a state is created locked where it is not possible to remove the shaft from the housing. The rotation member rotates an additional quarter turn, such that the control pieces provided at two locations facing each other with the axial center of the rotation member interposed therebetween, are moved from a rotational position where the control pieces come into contact with the respective housing parts, thereby causing the respective housing parts to engage the fixing groove, whereby the respective slide members can slide along the respective slide grooves. For this reason, the respective wrapping parts can slide in a direction that the wrapping parts reciprocally separate from the axial center of the linear motion member, and the coupling between the shaft fixing groove and the respective wrapping parts is released, and therefore, an unlocked state is created where it is possible to pull the shaft out of the housing.

Furthermore, in the mounting and dismounting device according to the present invention, the fixing groove is formed in such a way that the diameter of one part of the first shaft part is smaller than the diameter of the other part and an axial length it has a length to accommodate a height of the wrapping part, and the wrapping part has a circular arc surface along the outer periphery of the fixing groove at a contacting surface with the fixing groove.

According to this configuration, the shaft fixing groove and the wrapping part of the slide member are joined together by the wrapping part having an outer shape that conforms to the groove shape of the fixing groove that conforms to the fixing groove. For this reason, the coupling between the fixing groove and the enclosing part is done firmly, and therefore the shaft does not come out reliably from the housing.

Furthermore, the present invention provides a hinge device including: the mounting and dismounting device according to any one of the above aspects; and a rotary damper having a damper case that is mounted on the shaft or in the housing, and a rotary shaft that is housed in the damper case and in which a shaft end protruding from the damper case is connected to the object on one side or to the object on the other side, and provides resistance to the rotation of the object on one side or the object on the other side to which the shaft end is connected.

According to this configuration, it is possible to configure a hinge device that supports an object on one side, on an object on the other side so that it can be opened and closed freely, using a mounting and dismounting device capable of mounting and Easily disassemble the object on one side and the object on the other side without doing cumbersome and difficult operation.

However, in the present embodiment, the diameter of the third shaft part 11c is set to be larger than the diameters of the shaft parts. second and fourth 11b and 11d. Furthermore, an end face which is formed in a step protruding from the first shaft part 11a, from the second shaft part 11b, serves as a pressing surface 11b1 which comes into contact with an end face of the linear core 13 and presses the linear core 13.

Figures 7 (a), 7 (b), 7 (c) and 7 (d) are respectively a perspective view, a side view, a bottom view and a longitudinal sectional view of the stationary core 12.

The stationary core 12 has a hollow cylindrical shape, and in an end face at the upper end thereof, a first insertion opening 12a is formed which serves as an inlet and outlet for the shaft 11 having a diameter that allows the insertion of the first shaft part 11a and the second shaft part 11b of the shaft 11. The stationary core 12 is housed in the first space 16a of the housing 16 with the first insertion opening 12a exposed, and is attached thereto, as shown. previously described.

A second space 12b is formed in the hollow interior of the stationary core 12 to communicate with the first insertion opening 12a. Furthermore, in the inner periphery surrounding the second space 12b, a plurality of guide grooves 12c are formed along the insertion direction of the shaft 11 through the first insertion opening 12a, that is, along an axial central direction of the stationary core 12. In the present embodiment, four guide grooves 12c are respectively provided at four locations at equal intervals around the axial center of the shaft 11 and at the same length. Furthermore, the stationary core 12 has, on the other end face side where it faces the second space 12b, a guide wall 12d formed by causing the surface of the inner periphery wall to protrude from a terminal end of the slot. guide 12c. The protruding height of the guide wall 12d of the other end face of the stationary core 12 is the maximum at the terminal end portion of a guide groove 12c, gradually decreases towards the neighboring guide groove 12c, and becomes minimal. at a location reaching the neighboring guide groove 12c. The guide wall 12d configures a guide cam, and the projecting end face of the guide wall 12d comes into contact with an inclined end face 15e of a linear guide B 15d (described later) of the rotating core 15, serving thus as a raceway surface to guide the rotation of the rotating core 15.

Figure 8 (a) is a perspective view of the linear core 13 and the sliding device 14, Figures 8 (b), 8 (c), 8 (d) and 8 (e) are respectively a plan view, a side view, a bottom view and a longitudinal sectional view of the linear core 13, and Figures 8 (f) and 8 (g) are respectively a plan view and a side view of the sliding device 14.

The slide device 14 configures a slide member having a wrap part 14a and a slide guide part 14b. The wrapping part 14a has a semi-circular arc shape when viewed in planar view and engages with the locking groove 11a1 of the shaft 11 to wrap the shaft 11. The slide guide part 14b is T-shaped when viewed in a side view and is integrally formed with the wrapping part 14a to be continuous with the wrapping part 14a and projecting from an upper end face of the wrapping part 14a. The fixing groove 11a1 (refer to Figure 6) is formed by making the diameter of one part of the first shaft part 11a smaller than the diameter of the other part of the first shaft part 11a, and the depth of the groove is set to be a depth that accommodates the thickness of the envelope part 14a of the slider 14. Furthermore, the axial length of the fixing slot 11a1 is formed to have a length that accommodates the height of the envelope part 14a .

The wrapping part 14a has a circular arc surface along the outer periphery of the fixing groove 11a1 on the inner periphery which is a contact surface with the fixing groove 11a1, and the radius of the inner periphery has the same size than the radius of the shaft 11 in the part of the fixing groove 11a1. Therefore, the wrapping part 14a of the sliding device 14 engages the fixing groove 11a1 in close contact therewith and wraps around the shaft 11. The wrapping part 14a of the sliding device 14 engages the fixing groove 11a1 in close contact with it, whereby the clamping surfaces 14c and 14c that are formed on the upper and lower end faces of the casing part 14a come into contact with the clamping surfaces 11a2 and 11a2 of the shaft 11, which are rise at both ends of the fixing groove 11a1, and therefore movement in the central axial direction of the shaft 11 is restricted.

Linear core 13 also has a hollow cylindrical shape, and a second insertion opening 13a, serving as inlet and outlet for shaft 11, is formed in an end face of the closed upper end. The second insertion opening 13a is configured to have a diameter slightly larger than the diameter of the first shaft part 11a, into which the first shaft part 11a of the shaft 11 is inserted and the second shaft part 11b is not inserted, and is arranged to be continuous with the first insertion opening 12a when the linear core 13 is housed in the second space 12b of the stationary core 12. The second insertion opening 13a is formed in a shape and strength capable of supporting the shaft 11 in a case where a load is applied in a radial direction to the inserted shaft 11. A third space 13b is formed in the hollow interior of the linear core 13 to communicate with the second insert opening 13a. The envelope part 14a of the sliding device 14 is housed in the third space 13b. Furthermore, a slide groove 13c is formed in the second insertion opening 13a of the linear core 13 to communicate with the second insertion opening 13a. The sliding groove 13c houses the guide part of the slide 14b of the slide device 14 and fits into the slide guide portion 14b. Furthermore, the sliding groove 13c maintains the sliding guide part 14b so that it can slide in a direction orthogonal to the insertion direction of the shaft 11, that is, in the radial direction of the linear core 13 from the axial center. of linear core 13. In the present embodiment, a pair of slide grooves 13c are provided at two locations facing each other with the center of opening of the second insertion opening 13a interposed therebetween. The sliding device 14 is configured by a pair of members having a shape in which a cylindrical member is divided into two parts in a diametrical direction with respect to the central shaft thereof, formed symmetrically in a mirror image with respect to the center of opening of the second insert opening 13a, and arranged symmetrically in the respective slide grooves 13c. Therefore, the enveloping parts 14a of the sliding devices 14 envelop the fixing groove 11a1 from both sides with the axial center of the shaft 11 interposed between them. At this time, the slide guide part 14b of the slide device 14 comes into close contact with the outer periphery of the first shaft part 11a on the upper side of the fixing groove 11a1.

Furthermore, a linear guide A 13d that configures a first guided strip is formed on the outer periphery of the linear core 13 to project therefrom. Linear guide A 13d has a protruding shape which is fixed to the groove shape of guide groove 12c formed on the inner periphery of stationary core 12. That is, the protruding width dimension of linear guide A 13d is narrower. that the slot width dimension of the guide groove 12c, and the protruding height dimension of the linear guide A 13d is set to be slightly lower than the groove depth dimension of the guide groove 12c. Also, the protruding length dimension of the linear guide A 13d is set to be shorter than the slot length dimension of the guide groove 12c. In the present embodiment, four linear guides A 13d are provided, respectively, at four locations at equal intervals around the axial center of the linear core 13 and in the same shape and parallel to the axial center of the linear core 13. With this configuration, the core Linear 13 is housed in the second space 12b of the stationary core 12, whereby the linear guides A 13d are guided respectively by the guide grooves 12c so that they can move linearly in the insertion direction of the shaft 11 along the grooves guide 12c.

Furthermore, the third space 13b faces the other end face 13e of the linear core 13, which is open. The other end face 13e is formed to have a mountain shape having, as the upper part thereof, an end face part in a formation direction of each of the linear guides A 13d, that is, a extension line direction of each of the linear guides A 13d. Linear guides A 13d are provided at four locations, and therefore the tops of the mountain shapes are formed at four locations on the other end face 13e. The other end face 13e configures a mountain-shaped cam and contacts the sloping end face 15e of the linear guide B 15d (described below) of the rotating core 15, thus serving as a track surface for rolling to guide the rotation of the rotary core 15.

Figures 9 (a), 9 (b), 9 (c) and 9 (d) are respectively a perspective view, a plan view, a side view and a longitudinal section view of the rotary core 15.

The rotary core 15 has a cylindrical shape having a small diameter portion 15a with a small outer diameter and a large diameter portion 15b with a large outer diameter, and an insert hole 15c penetrates and opens along the axial center. of the same. The insertion hole 15c is arranged to be continuous with the second insertion opening 13a of the linear core 13 when the small diameter part 15a fits into the third space 13b of the linear core 13. The diameter of the insertion hole 15c is set by same diameter as that of the second insertion opening 13a and has a dimension to allow insertion of the first shaft part 11a of the shaft 11.

The linear guide B 15d that configures a second guided strip is formed on the outer periphery of the large diameter portion 15b to protrude therefrom. In the present embodiment, four linear guides B 15d are provided, respectively, at four locations at equal intervals around the axial center of the rotary core 15 and in the same shape and parallel to the axial center of the rotary core 15. The linear guide B 15d has a shape that fits in a predetermined length to the guide groove 12c of the stationary core 12, and the protruding width and protruding height dimensions of the linear guide B 15d are manufactured to be equal to those of the linear guide A 13d of the linear core 13. The upper end face of the linear guide B 15d is manufactured to be the slanted end face 15e. The inclined end face 15e is inclined at the same angle as the inclination angle of the mountain shape which is formed on the other end face 13e of the linear core 13 and the inclination angle of the guide wall 12d which is it forms in the stationary core 12, and functions as a slide cam.

The lower surface of the large diameter part 15b is set as a biasing surface that is biased by the spring 17. The spring 17 forms an elastic member that biases the linear core 13 and the rotary core 15 towards the end face side. of the stationary core 12. The spring 17 exerts an elastic force along the central axes of the rotating core 15, the linear core 13, the stationary core 12 and the shaft 11. In the present embodiment, a compression coil spring is used like spring 17. However, there is no limitation on this.

In a state where the small diameter part 15a of the rotating core 15 fits into the third space 13b of the core Linear 13 and Linear Core 13 and Rotary Core 15 are housed in Stationary Core 12, Linear Guide A 13d is housed in Guide Groove 12c, and Linear Guide B 15d is partially housed in Guide Groove 12c. In this state, the distance between the linear guide A 13d and the linear guide B 15d is the shortest and the linear guide B 15d is adjusted by a predetermined length to the guide groove 12c. At this time, in the rotating core 15, the large diameter part 15b is housed in the second space 12b of the stationary core 12 such that the linear guide B 15d is guided in a predetermined length by the guide groove 12c and can move linearly by a predetermined length in the insertion direction of the shaft 11.

Linear guide B 15d is set to have a protruding length dimension to deviate from guide groove 12c if slanted end face 15e is pushed over the top of the mountain-shaped shape that is formed in the other end face 13e of the linear core 13 beyond the projecting height of the guide wall 12d, such that the inclined end face 15e separates from the linear core 13 beyond the projecting height of the guide wall 12d. When the linear guide B 15d deviates from the guide groove 12c, the rotating core 15 becomes rotatable with respect to the linear core 13 while the small diameter portion 15a rotatably fits into the third space 13b of the linear core 13.

Further, on the upper end face of the small diameter part 15a, a control piece 15f is formed in a protruding shape to extend from the upper end face. The outer periphery of the control piece 15f is formed as a circular arc surface flush with the outer periphery of the small diameter portion 15a, and the end face of the control piece 15f is formed on the side facing to the axial center of the rotary core 15 as a plane. The control piece 15f rotates, thus coming into contact with the outer periphery of the envelope part 14a of the sliding device 14, whereby the sliding device 14 with the sliding guide portion 14b held in the sliding groove 13c slides in a direction towards the axial center of the linear core 13. Next, the envelope part 14a engages with the fixing groove 11a1 formed in the first shaft part 11a inserted into the first and second insertion openings 12a and 13a and the insertion hole 15c. The shaft 11 shown in Figure 6 is set to have a length dimension in which, when the other end of the shaft 11 is inserted into the housing 16, the first long shaft part 11a is further down the side than the slot of Fixing 11a1 is located in the insertion hole 15c, the fixing groove 11a1 is located in the third space 13b of the linear core 13, and the first short shaft part 11a more on the upper side than the fixing groove 11a1 is located in the second insertion opening 13a of the linear core 13.

In the present embodiment, a pair of control pieces 15f is provided at two locations facing each other 180 ° with the axial center of the rotary core 15 interposed between them. The planes facing each other of the control parts 15f are spaced from each other a distance W to clamp the pair of wrapping parts 14a fitted into the fixing slots 11a1, and the space between the planes serves as a space for lock restriction. If the rotary core 15 rotates together with the control pieces 15f in such a way that the respective housing parts 14a are located in the blocking restriction space, as shown in the plan view of FIG. 10 (a), and the The planes of the control pieces 15f come into contact with the arc-shaped outer peripheral surfaces of the wrapping parts 14a, the wrapping parts 14a being in a close contact state to fit the fixing groove 11a1. In this state, the clamping surfaces 14c of the envelope part 14a come into contact with the clamping surfaces 11a2 of the shaft 11, such that movement in the axial direction of the shaft 11 is restricted. The contact location between the surface The circular arc-shaped outer peripheral of the wrapping part 14a and the planes of the control piece 15f is considered as a locking point (a point L) and is shown as a point L in Figures 8 (a) and 9 ( to).

The locking point of the wrapping part 14a is at the center position of the arc of the outer periphery and the locking point of the control piece 15f is at the center position in the width direction in the plane. If the rotary core 15 rotates together with the control pieces 15f from this state where the locking points correspond to each other, such that the locking points of the control pieces 15f rotate 90 ° to the positions shown in the view In plan of figure 10 (b), the movement of the enveloping parts 14a that have been confined in the restriction space is released. For this reason, the wrapping parts 14a can move in directions away from each other indicated by arrows in the drawing. Therefore, the wrapping parts 14a are separated from the fixing groove 11a1, thereby allowing movement in the axial direction of the shaft 11.

Figures 10 (c) and 10 (d) are perspective views when the assembly and disassembly device 4 is viewed obliquely from above with the shaft 11 removed, in which Figure 10 (c) shows a state where the pieces of Control 15f are in the rotational positions shown in Fig. 10 (a), and Fig. 10 (d) shows a state in which the control parts 15f are rotated 90 ° to be in the rotational positions shown in the Figure 10 (b) and the wrapping parts 14a are separated from each other.

In the state shown in Fig. 10 (c), a distance Va between the inner peripheries facing each other of the enveloping portions 14a is less than a diameter $ of the second insertion opening 13a of the linear core 13 ( It goes <$). For this reason, a state is created where the inner peripheries of the respective shell parts 14a enter into the inner periphery of the second insertion opening 13a, such that the respective shell parts 14a contract. In this state, the respective envelope portions 14a are engaged with the fixing grooves 11a1 in close contact therewith. Figures 11 (a) and 11 (b) are perspective views showing the relative relationship between the wrapping parts 14a and the fixing groove 11a1 in the locked state, in which Figure 11 (a) is a perspective view when the locked state is viewed obliquely from above and Fig. 11 (b) is a perspective view seen from the bottom side. In Figures 11 (a) and 11 (b), the same parts as those in Figures 6 and 10 are indicated by the same reference numerals, and their description is omitted.

On the other hand, in the state shown in Fig. 10 (d), a distance Vb between the inner peripheries facing each other of the enveloping portions 14a is greater than the diameter $ of the second insertion opening 13a of the core. linear 13 (Vb> $). For this reason, a state is created in which the inner peripheries of the respective envelope portions 14a protrude outwardly from the inner periphery of the second insertion opening 13a, such that the respective envelope portions 14a are expanded. In this state, the respective wrapping parts 14a are separated from the fixing groove 11a1, in such a way that the coupling between the covering parts 14a and the fixing groove 11a1 is released. Figures 12 (a) and 12 (b) are perspective views showing the relative relationship between the housing parts 14a and the fixing groove 11a1 in the unlocked state, in which Figure 12 (a) is a perspective view when the unlocked state is viewed obliquely from above and Fig. 12 (b) is a perspective view as seen from the bottom side. In Figures 12 (a) and 12 (b), the same parts as those in Figures 6 and 10 are indicated by the same reference numerals, and their description is omitted.

The mounting and dismounting device 4 according to the present embodiment is configured with the shaft 11 having an end that is mounted on the side of the toilet seat / toilet lid unit 2 and the housing 16 that is mounted on the side of the toilet bowl 3, as described above. The stationary core 12 is attached to the first space 16a inside the housing 16, and the linear core 13 and the rotary core 15 are housed in series in the second space 12b inside the stationary core 12 with the first and second insertion openings. 12a and 13a communicating with insertion hole 15c. The small diameter portion 15a of the rotary core 15 fits into the third space 13b inside the linear core 13 housed in the second space 12b. Rotating core 15 and linear core 13 are urged towards the end face side of stationary core 12 by spring 17.

In a locking operation in which the toilet seat / toilet lid unit 2 is mounted and fixed to the toilet bowl 3, the following first operation is performed, whereby a second operation and a third operation are performed consecutively .

(First operation)

The assembly of the toilet seat unit / toilet lid 2 on the toilet bowl 3 is done by grasping the toilet seat unit / toilet lid 2, inserting the other end of the tree 11 mounted on the toilet seat unit / toilet lid 2 in the first insertion opening 12a of the stationary core 12 fixed to the housing 16 mounted on the toilet bowl 3, and pressing the toilet seat unit / toilet lid 2 against the toilet bowl 3. The Another end of shaft 11 inserted into the first insertion opening 12a of the stationary core 12 passes through the first insertion opening 12a. However, the second shaft part 11b cannot pass through the second insertion opening 13a formed in the linear core 13 and the pressing surface 11b1 of the second shaft part 11b comes into contact with an end face of the core. linear 13 around the second insertion opening 13a. In this case, if the toilet seat / toilet lid unit 2 is pushed vertically downward with a certain force exceeding the elastic force of the spring 17 and is pressed against the toilet bowl 3, the second shaft part 11b pushes linear core 13.

(Second operation)

The operation of the linear core 13 in a rectilinear movement direction parallel to the insertion direction of the shaft 11 is restricted by the linear guide A 13d and the guide groove 12c. Therefore, with the pushing force of the toilet seat / toilet lid unit 2 towards the toilet bowl 3, the linear core 13 moves linearly to the other end face side of the housing 16 against the force. elastic of the spring 17 while the linear guide A 13d is guided by the guide groove 12c. The rotary core 15 is operatively arranged in contact with the other end face 13e of the linear core 13.

A partial interval in a predetermined length of the linear guide B 15d of the rotary core 15 is housed in the guide groove 12c, and in this partial interval, operation in the direction of rectilinear movement parallel to the insertion direction of the shaft is restricted. 11. Therefore, the inclined end face 15e of the rotating core 15 is pushed over the top of the mountain-shaped shape formed on the other end face 13e of the linear core 13 by the linear movement described above of the linear core. 13, such that the rotating core 15 moves linearly together with the linear core 13 on the other side of the end face of the housing 16 against the elastic force of the spring 17. At this time, the linear guide B 15d is fixed to the guide groove 12c only in a partial interval of a predetermined length and therefore if the rotary core 15 moves linearly as it is pushed beyond the projecting height of the guide wall 12d, linear guide B 15d deviates from guide groove 12c.

Figure 13 is a partially cutaway side view showing, in cutaway, the mounting and dismounting device 4 in the pushed state where the linear guide B 15d has deviated from the guide groove 12c upon being pushed. by the shaft 11. In Figure 13, the same parts as those in Figure 5 are indicated by the same reference numerals, and their description is omitted. In this pushing state, as shown in the drawing, the linear core 13 and the rotary core 15 are driven under the first interior space 12b of the stationary core 12 and the inclined end face 15e of the linear guide B 15d is located at a position lower than the projecting height of guide wall 12d indicated by the broken line.

If the linear guide B 15d deviates from the guide groove 12c, the rotating core 15 becomes rotatable about the axial center thereof while being guided by the third space 13b of the linear core 13, so that the part of small diameter 15a. For this reason, the inclined end face 15e of the rotary core 15 slides upwards on the inclined surface of the other mountain-shaped end face 13e of the linear core 13, such that the rotary core 15 rotates with the other. inclined end face 13e of linear core 13 as a raceway surface.

Thereafter, if the force pressing the toilet seat / toilet lid unit 2 against the toilet bowl 3 becomes equal to or less than the elastic force of spring 17, spring 17 pushes rotating core 15, thereby pushing it back towards the end face side of the housing 16. If the rotary core 15 is pushed back, the inclined end face 15e comes into contact with the projecting end of the guide wall 12d. As the protruding height of the guide wall 12d gradually decreases towards the neighboring guide groove 12c, the rotating core 15 is pushed back towards the end face side of the casing 16 being pushed by the spring 17, whereby the rotary core 15 rotates further while sloping end face 15e is guided by the projecting end of guide wall 12d. In the present embodiment, since guide grooves 12c are provided at four locations at equal intervals around the axial center of stationary core 12, rotating core 15 rotates 90 °.

(Third operation)

With this rotation, the control pieces 15f existing in the third space 13b of the linear core also rotate 13. The slide guide parts 14b of the slide devices 14 are slidably held in the slide grooves 13c of the linear core 13, and the rotary control pieces 15f come into contact with the enclosing parts 14a of the sliders 14, thereby causing the sliders 14 to slide along the slide grooves 13c in a direction towards the axial center of the linear core 13. If the rotating core 15 rotates such that the inclined end face 15e reaches the neighboring guide groove 12c, and the rotating core 15 rotates 90 °, the control parts 15f also rotate 90 °, such so that the locking points of the control parts 15f and the housing parts 14a coincide with each other, as shown in Fig. 10 (a).

For this reason, the wrapping parts 14a of the slides 14 engage with the fixing groove 11a1 formed in the first shaft part 11a of the shaft 11, in a way that interposes the fixing groove 11a1 between them, as shown shown in Figure 11. The housing parts 14a are engaged with the fixing groove 11a1, so that the shaft 11 cannot come out of the housing 16, and thus the locked state is created where the toilet seat / lid unit toilet 2 is mounted and fixed to the toilet bowl 3. If the rotating core 15 rotates 90 °, such that the inclined end face 15e reaches the neighboring guide groove 12c, the linear guide B 15d is pushed back when pushed by the spring 17 and returns to the initial state where the linear guide B 15d fits the neighboring guide groove 12c by a predetermined length.

Figure 14 is a partially cutaway side view showing, in cutaway manner, the mounting and dismounting device 4 in this locked state. In Figure 14, the same parts as those in Figure 13 are indicated by the same reference numerals, and their description is omitted. In the locked state, as shown in the drawing, the control pieces 15f hold the outer peripheries of the shell parts 14a and the inner peripheries of the shell parts 14a interpose the fixing groove 11a1 therebetween.

Also, a removal operation of the toilet seat / toilet lid unit 2 from the toilet bowl 3 is performed by releasing the locked state in the following fourth operation and continuing a fifth operation and a sixth operation.

(Fourth operation)

The toilet seat / toilet lid unit 2 mounted on the toilet bowl 3 is grasped and pressed again vertically downwards against the toilet bowl 3.

(Fifth operation)

The fifth operation is the same as the second operation at the time of the lock operation. That is, the linear core 13 is pushed by the second shaft part 11b of the shaft 11 with the force that presses the toilet seat / toilet lid unit 2 against the toilet bowl 3, thereby moving linearly back towards the other end face side of the casing 16. The rotating core 15 also moves linearly back toward the other end face side of housing 16, together with linear core 13 with linear movement of linear core 13. If rotary core 15 moves linearly as it is pushed past the projecting height of guide wall 12d, the linear guide B 15d deviates from guide groove 12c again.

If the linear guide B 15d deviates from the guide groove 12c, the rotary core 15 becomes rotational again around the axial center thereof. For this reason, the rotating core 15 rotates with the other inclined end face 13e of the linear core 13 as a raceway surface. Thereafter, if the force pressing the toilet seat unit / toilet lid 2 against the toilet bowl 3 becomes equal to or less than the elastic force of the spring 17, the rotating core 15 is pushed back towards the end face side of the casing 16 which is pushed by the spring 17, and the rotating core 15 rotates 90 ° again while the inclined end face 15e is guided by the projecting end of the guide wall 12d.

(Sixth operation)

With this rotation, the control piece 15f also rotates, and the control piece 15f moves from a rotational position where the envelope portion 14a engages with the fixing groove 11a1. If the control piece 15f rotates 90 °, such that the locking point of the control piece 15f is separated by 90 ° from the locking point of the enclosing portion 14a, as shown in Figure 10 (b), the slider 14 becomes slippery in a direction in which the wrapping part 14a is spaced from the fixing groove 11a1. As a result, the shaft 11 comes out of the housing 16, whereby the wrapping parts 14a move away from each other when pushed by the shaft 11, and thus the unlocked state shown in figure 12 is created where it is possible to remove the shaft 11 of the casing 16. If the rotating core 15 rotates 90 °, such that the inclined end face 15e reaches the neighboring guide groove 12c, the linear guide B 15d is pushed back by being pushed by the spring 17, returning from this mode to the initial state where the linear guide B 15d is fixed to the neighboring guide groove 12c by a predetermined length.

Figure 5 described above shows the mounting and demounting device 4 in this unlocked state. In this drawing, the control part 15f is not shaded by the shaft 11. However, in the unlocked state, the control part 15f does not exist in a sliding direction of the wrapping part 14a, such that the device slide 14 becomes slippery along slide groove 13c.

The linear guides B 15d provided at four locations at equal intervals around the axial center of the rotating core 15 deviate from the guide grooves 12c provided at four locations at equal intervals around the axial center of the stationary core 12, whereby the rotation of the rotary core 15 described above. Therefore, the deviation of the linear guide B 15d from the guide groove 12c is performed every time the rotary core 15 rotates one quarter, and thus the locked state and the unlocked state of the shaft 11 appear alternately.

Thus, according to the mounting and dismounting device 4 of the present embodiment, the operation of mounting the toilet seat unit / toilet lid 2 on the toilet bowl 3 and the operation of removing the toilet seat unit toilet / toilet lid 2 from the toilet bowl 3 are made by simply pressing the toilet seat unit / toilet lid 2 against the toilet bowl 3. For this reason it is possible to easily remove the toilet seat / lid unit of toilet bowl 2 from the toilet bowl 3 without performing a cumbersome and difficult operation in which an unlocking operation is performed by pushing a pressure member simultaneously with both hands with respect to the respective mounting and dismounting devices that make up two hinge devices , as in the related art mounting and demounting device disclosed in EP 2324745 A, which is used for a western style toilet. Therefore, it is possible to easily carry out the cleaning or maintenance of the western-style toilet, or the job of replacing the toilet seat unit / toilet lid 2.

Furthermore, according to the mounting and dismounting device 4 of the present embodiment, the insertion and extraction of the shaft 11 into and from the casing 16 are performed by sliding the sliding devices 14 in a direction orthogonal to the insertion direction of the shaft 11 , thus making the fixing groove 11a1 of the shaft 11 and the wrapping parts 14a of the slides 14 engage each other or releasing the engagement between the fixing groove 11a1 and the wrapping parts 14a. For this reason, the locking operation of creating a state that causes the shaft 11 not to be removed from the housing 16, and the unlocking operation of creating a state that causes the shaft 11 to be removed from the housing 16 are performed independently. of the rotational position of the shaft 11 and the rotational position of each member on the side of the casing 16, and the assembly and disassembly of the toilet seat unit / toilet lid 2 in and of the toilet bowl 3 they can be easily performed without taking into account the rotational position of each member. Therefore, regardless of the rotational position of shaft 11 or rotary core 15 at the time of insertion of shaft 11 into housing 16, it is possible to easily insert shaft 11 into housing 16, which is a mating member. .

Furthermore, according to the mounting and dismounting device 4 of the present embodiment, the linear core 13 is guided with the linear guides A 13d provided at four locations at equal intervals around the axial center thereof fixed in the guide grooves 12c provided at four locations at equal intervals around the axial center of the stationary core 12, and thus the linear core 13 is linearly moving in a stable manner. Furthermore, the rotating core 15 is also guided by the four guide grooves 12c because the end faces inclined 15e of the linear guides B 15d provided at four locations at equal intervals around the axial center of the rotary core 15 are pushed by the tops of the mountain-shaped shapes provided at four locations at equal intervals on the other end face 13e of the linear core 13, and therefore, the rotating core 15 moves linearly stably together with the linear core 13.

Furthermore, according to the mounting and dismounting device 4 of the present embodiment, the fixing groove 11a1 of the shaft 11 and the wrapping part 14a of the sliding device 14 are coupled to each other by the wrapping part 14a having an outer shape that It conforms to the shape of the slot of the fixing slot 11a1 that fits the fixing slot 11a1. For this reason, the coupling between the fixing groove 11a1 and the enveloping part 14a is carried out firmly, such that the shaft 11 does not come out reliably from the housing 16.

Furthermore, according to the present embodiment, it is possible to provide the hinge devices 1a and 1b that support the toilet seat / toilet lid unit 2 on the toilet bowl 3 so that they can be opened and closed freely, using the mounting and dismounting devices 4 capable of easily mounting and dismounting the toilet seat unit / toilet lid 2 on and from the toilet bowl 3 without making a cumbersome and difficult operation.

In the embodiment described above, a case has been described where the mounting and dismounting device 4 is configured by mounting the shaft 11 in the shock absorber box 8 and mounting the casing 16 in the toilet bowl 3. However, on the contrary of this , it is also possible to configure the mounting and dismounting device 4 by mounting the casing 16 on the shock absorber box 8 and mounting the shaft 11 on the toilet bowl 3.

Furthermore, the mounting of the shaft 11 on the damper box 8 is done using the mounting screw 18, and the mounting of the housing 16 on the toilet bowl 3 is done using the mounting jig 21. However, these forms of Assembly is not limited to the forms of the embodiment described above. As long as the shaft 11 is fixed to the damper box 8 and the housing 16 is fixed to the toilet bowl 3, the same operation and effects as those of the above-described embodiment can be shown even in other mounting methods.
