Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door opening and closing mechanism for opening and closing a sliding door which is opened and closed by sliding and turning.

[0002]

2. Description of the Related Art For example, as a luggage compartment door of a one-box car or the like, a slide door 12 which is slid in the front-rear direction of a vehicle body 10 to be opened and closed as shown in FIG. In order to open and close the slide door 12, three rails 14, 16, 18 extending in the front-rear direction of the vehicle body 10 are arranged at the upper part, the central part, and the lower part of the slide door 12 on the vehicle body 10. . Sliding door 1
Reference numeral 2 is configured to slide while being supported by these three rails 14, 16, 18.

In recent years, a sliding door may be used as the cab door 20 in order to facilitate getting on and off the vehicle even when the vehicle is stopped in a narrow place such as an alley. In this case, since the length of the portion of the vehicle body 10 corresponding to the upper portion of the cab door 20 is short, a rail supporting the cab door 20 cannot be arranged in this portion. In addition, in a portion of the vehicle body 10 corresponding to a lower portion of the driver's cab door 20, a rail for supporting the driver's cab door 20 cannot be arranged because it interferes with getting on and off. Therefore, when a sliding door is adopted as the cab door 20, the rail 22 extending in the front-rear direction of the vehicle body is connected to the cab door 2
In addition, a slide door opening / closing mechanism 24 for opening and closing the cab door 20 is provided at a portion of the vehicle body 10 corresponding to the rear end of the rail 22 when the cab door 20 is closed. Attach. The rail 22 is also a component of the slide door opening / closing mechanism 24, and the slide door opening / closing mechanism 24 is provided with a member (not shown) that is guided by the rail 22 and slides on the rail 22.

A conventional sliding door opening / closing mechanism in which a sliding door is employed as the cab door as described above will be described (see Japanese Patent Publication No. 4-65552).

A guide plate that slides with the cab door is formed on a rail incorporated in the center of the cab door. A strong and large-sized sliding lock plate is disposed near the guide plate. The sliding lock plate is configured so as to be raised or lowered in conjunction with the sliding of the door, and the door is slid or pivoted by the undulation. The sliding door opening / closing mechanism includes an outer arm and an inner arm that connect the door and the vehicle body. An arm lock plate is disposed on the inner arm of the two arms, and the arm lock plate is It serves as a link for linking the sliding lock plate and the inner arm. Therefore, the arm lock plate is high in strength and relatively large in size. Further, the inner arm is configured to rotate in conjunction with the undulation of the sliding lock plate.

[0006]

As described above, the conventional sliding door opening / closing mechanism has a relatively large and robust arm lock plate or slide lock plate. These arm lock plates and sliding lock plates are usually manufactured by machining a casting in consideration of its strength. Therefore, there is a problem that the cost is high and the size is large as described above.

Generally, a driver's cab door of a vehicle such as a one-box car produced by an automobile manufacturer is attached to a vehicle body by a hinge or the like, and has a structure in which the cab door is opened and closed by rotating the cab door. I have. Since the rotating door opening / closing mechanism for opening / closing the cab door with a hinge or the like is small in size and attached to the front end of the door, the opening / closing mechanism does not protrude into the cab at all. For this reason, a relatively wide seat is used as a seat in the driver's cab.

However, as described above, a mechanism for opening and closing the driver's cab door is provided to facilitate the getting on and off the vehicle even when the vehicle is stopped in a narrow place such as an alley. The door opening / closing mechanism may be modified to a sliding door opening / closing mechanism. In this case, the conventional slide door opening / closing mechanism described above is large in size and protrudes into the cab. For this reason, the wide seat in the driver's cab may obstruct the slide door opening / closing mechanism because it is in the way, so if the mechanism for opening and closing the driver's cab door is changed from a rotating door opening / closing mechanism to a sliding door opening / closing mechanism, Usually, a narrow sheet is custom-made and replaced with a wide sheet to secure a space for mounting a sliding door opening / closing mechanism.
For this reason, the cost of purchasing a narrow sheet or the cost of replacing a sheet is required, which increases the cost. Also,
There is also a problem that the time required for the sheet replacement operation is delayed, and the delivery date is delayed.

In view of the above circumstances, an object of the present invention is to provide a small-sized and low-cost sliding door opening / closing mechanism.

The sliding door opening / closing mechanism 30 opens and closes the sliding door 20 (FIG. 16).
), And is mounted at the same position as the conventional slide door opening / closing mechanism 24 shown in FIG.

The slide door opening / closing mechanism 30 has a rail 40 incorporated in the slide door 20 (see FIG. 16). The rail 40 extends in the direction in which the slide door 20 slides (the direction of the arrow A and the opposite direction, which is an example of the slide direction according to the present invention). Slightly shorter. At the center of the rail 40 in the longitudinal direction (sliding direction), a rectangular parallelepiped knocking protruding downward from the rail 40 (which is an example of the turning permitting member according to the present invention) 42 is fixed. The tip of the knocking 42 is an inclined surface 42a inclined inward. Also,
A knock slide (an example of a slide inhibition member according to the present invention) 44 protruding downward from the rail 40 is fixed to a rear end portion of the rail 40 in the longitudinal direction (rearward in the direction of the arrow A). The knock slide 44 is formed by, for example, bending a plate, and has a shape in which the letter “C” is inverted. A front slope 44a is formed at the front of the knock slide 44, and a rear slope 4 at the rear.
4b is formed.

The slide door opening / closing mechanism 30 includes a slide member 50 slidably fixed to the rail 40. The sliding member 50 includes a vertical wall 52 extending in the longitudinal direction of the rail 40 and in the height direction of the vehicle (not shown), and two mutually bent right-angled members from the vertical wall 52 toward the vehicle interior. Parallel side walls 54 and 56 are provided.

A roller base 58 having a substantially U-shaped cross section and extending in the longitudinal direction of the rail 40 is fixed to the upper part of the vertical wall 52. Rollers 58a, 58b and rollers 58c, 58d whose rotation axes are orthogonal to each other are rotatably fixed to the front and rear ends of the roller base 58, respectively. By sliding the slide door 20 (FIG. 16), the rollers 58a and 58c slide on the side wall 40a of the rail 40, and the rollers 58b and 58d slide on the intermediate wall 40b of the rail 40.

At the center of the vertical wall 52 in the height direction, a rotating shaft 6 is provided.
A slide stopper 60 that rotates in parallel with the vertical wall 52 around the center 0a is fixed to be freely rotatable. One end of a tension coil spring 62 is fixed to the front end of the slide stopper 60, and the other end of the tension coil spring 62 is
It is fixed to. For this reason, the slide stopper 60 is urged in the direction of arrow B.

One end 6 of both the first arm 64 and the second arm 66 is provided between the two parallel lateral walls 54 and 56.
4a and 66a are rotatably sandwiched and fixed. The first arm 64 and the second arm 66 are parallel to each other, and rotate while keeping the state parallel to each other when the slide door 20 (see FIG. 16) turns. The other ends 64b and 66b of both the first arm 64 and the second arm 66 are rotatably fixed to a fixing member 80 attached to a vehicle body (not shown). The fixing member 80 is fixed to the vehicle body.

The rotating shaft 6 of the other end 64b of the first arm 64
The other end 70b of a rod-shaped swing stopper 70 urged in the direction of arrow C by a coil spring 68 is rotatably fixed to 4c. One end 70a of the swing stopper 70 has a concave portion 72 having an open mouth toward the rear of the vehicle body.
(See FIG. 4). A tip portion 74a of a bar-shaped check swing 74 formed on the upper surface of the lateral wall 54 and extending in the sliding direction is fitted into the concave portion 72. In this state, the swing stopper 70 is locked to the check swing 74 and the rotation of the first and second arms 64 and 66 is prohibited, and the slide door 20 cannot turn.

At the distal end 64a of the first arm 64, a substantially fan-shaped plate stopper 76 projecting from the distal end 64a and extending parallel to the lateral wall 54 is formed. The plate stopper 76 rotates together with the first arm 64 to move the slide stopper 60 to a predetermined position described later.
The slide of the slide door 20 is prohibited in cooperation with the above. The above-mentioned slide member 50, fixing member 80, first and second members
An example of the holding member according to the present invention is configured by the arms 64 and 66, the swing stopper 70, and the like.

The operation of the sliding door opening / closing mechanism 30 will be described with reference to FIGS. 1 to 3 and FIGS. 4 to 9 described above.

FIG. 4 is a plan view showing a state in which the locking between the swing stopper 70 and the check swing 74 is released by the knocking 42 so that the first and second arms 64 and 66 can rotate slightly. . FIG. 5 shows the first
FIG. 9 is a perspective view showing a state in which second arms 64 and 66 are rotating. FIG. 6 is a plan view showing a state where the first and second arms 64 and 66 have finished rotating and the slide door is closed, and FIG. 7 is a perspective view showing a part of FIG. 6 in an enlarged manner. . FIG. 8 is a plan view showing the movement of the knocking swing 42, the swing stopper 70, and the check swing 74 that move as the slide door slides. FIG. 9 is a plan view showing the movement of the knock slide 44, the slide stopper 60, and the plate stopper 76 that move as the slide door slides.

When the slide door 20 (see FIG. 16) is completely open, as shown in FIGS. 1 and 2, the slide stopper 20 is in the concave portion 72 of the swing stopper 70 which is urged in the direction of arrow C by the coil spring 68. The tip 74a of the check swing 74 is fitted. As a result, the swing stopper 70 is locked to the check swing 74, and the rotation of the first and second arms 64 and 66 in the direction of arrow D (the direction opposite to the direction of arrow C) is prohibited. On the other hand, in order to prohibit the rotation of the first and second arms 64 and 66 in the direction of arrow C, a stop plate 82 having a substantially L-shaped cross section is formed on the fixing member 80. The other end 64b of the first arm 64 abuts on the stop plate 82, and the rotation of the first and second arms 64 and 66 in the direction of arrow C is prohibited. Therefore, the sliding door cannot be turned in any direction.

When the slide door is closed, the slide door is slid in the direction of arrow A. When the slide door slides about half the length of the rail 40 and the slide member 50 is located at the center of the rail 40, the inclined surface 42a of the knocking 42 pushes one end 70a of the swing stopper 70 in the direction of arrow A. As a result, as shown in FIG.
Is released, and the rotation of the first and second arms 64 and 66 in the direction of arrow D is permitted. As a result, the sliding door starts to turn. The position where the rotation is allowed is an example of the turning allowable position according to the present invention. Note that when the sliding door starts turning, the sliding of the sliding door is prohibited. A mechanism for this will be described later.

FIG. 8 shows the first and second arms 64 and 66.
The positional relationship between the swing stopper 70, the check swing 74, and the knocking 42, which prohibits and permits the rotation of, is clearly shown. FIG. 8A shows the knocking 4
2 shows a state immediately after contact with the swing stopper 70. In this state, since the swing stopper 70 is locked to the check swing 74, the first and second arms 6
4, 66 cannot rotate in the direction of arrow D. FIG. 8 (b)
The state where the knocking 42 has slightly pressed the swing stopper 70 is shown.
The lock between 0 and the check swing 74 has begun to be released. FIG. 8C shows a state in which the knocking 42 further pushes the swing stopper 70 to release the lock between the swing stopper 70 and the check swing 74. FIG. 8D shows a state in which the knocking 42 is separated from the swing stopper 70 and the lock between the swing stopper 70 and the check swing 74 is completely released. 2
The arms 64 and 66 can rotate in the direction of arrow D.

The first and the second together with the swing stopper 70
FIG. 5 shows a state in which the arms 64 and 66 are further rotated in the direction of arrow D than the state shown in FIG. 8D.
As shown in FIG. 5, one end 70 of the swing stopper 70
a is the first state in a state where it is still in contact with the check swing 74.
And the second arms 64 and 66 rotate in the direction of arrow D. As the first and second arms 64 and 66 rotate in the direction of arrow D, the slide door pivots around the fixing member 80 (see FIG. 4) to close the slide door.

When the slide door is completely closed, as shown in FIGS. 6 and 7, the first and second arms 6
4 and 66 overlap and almost enter the inside of the rail 40, and about half of the fixing member 80 enters the inside of the rail 40. Since the rail 40 is incorporated in the slide door, when the slide door is closed, almost all of the first and second arms 64 and 66 and about half of the fixing member 80 enter the inside of the slide door. Therefore, the sliding door opening / closing mechanism 30 needs to protrude from the sliding door in a small amount, and accordingly the driver's cab is widened.
Further, among the components of the slide door opening / closing mechanism 30, the one having a relatively large size is only the holding member 80 as shown in FIG. 1. For this reason, the sliding door opening / closing mechanism 30
Is small in size as a whole. Further, since the slide door opening / closing mechanism 30 can be manufactured by, for example, press-molding an iron plate, it can be manufactured at a lower price than a cast product.

As described above, the sliding door opening / closing mechanism 30 is configured to prohibit the sliding of the sliding door when the turning of the sliding door starts. This mechanism will be described mainly with reference to FIG.

FIG. 9 shows a knock slide 44 for prohibiting / allowing the slide of the slide door and a slide stopper 6.
0 and the positional relationship between the plate stopper 76 are clearly shown. FIG. 9A illustrates a state immediately before the knock slide 44 contacts the slide stopper 60. In this state, the slide door is sliding in the direction of arrow A. FIG. 9B shows a state in which the knock slide 44 slightly rotates the slide stopper 60 in the direction opposite to the direction of the arrow B. In this state, the slide door slides in the direction of the arrow A. Just before the end. FIG.
(C) shows that the knock slide 44 has the slide stopper 60.
5 shows a state in which the slide door has slid in the direction of arrow A after climbing over the mountain portion 60b. In this state, the slide member 50 is located at the end of the rail 40. In this state, the slide door cannot slide in the direction of arrow A and in the opposite direction. The position of the knock slide 44 at this time is an example of the slide prohibition position according to the present invention. Almost simultaneously with this state, the first arm 64 starts rotating in the direction of arrow D. That is, FIG.
The timing of the state shown in FIG. 8C and the timing of the state shown in FIG. 8C are almost the same, and this timing is an example of the predetermined timing according to the present invention.

FIG. 9D shows a state in which the first arm 64 has rotated considerably in the direction of arrow D. In this state, when the slide door attempts to slide in the direction opposite to the direction of arrow A, the knock slide 44 is moved. The rear inclined surface 44b comes into contact with the mountain portion 60b of the slide stopper 60. But,
Since the distal end portion 60c of the slide stopper 60 comes into contact with the plate stopper 76 and the slide stopper 60 cannot rotate in the direction opposite to the arrow B direction, the knock slide 44
Cannot move in the direction opposite to the arrow A direction. As a result,
The sliding door cannot slide in the direction of arrow A and in the opposite direction.

As described above, the timing of the state shown in FIG. 9 (c) (slide end state) and the timing of the state shown in FIG. 8 (c) (swing start state) are almost the same. When closing the sliding door, the sliding door starts turning after the sliding of the sliding door ends. Conversely, when opening the slide door, the slide door starts sliding after the swing of the slide door is completed. Therefore, it is possible to prevent the sliding door from turning during sliding and damaging the vehicle body.

Next, referring to FIGS. 10 to 15,
A second embodiment of the sliding door opening and closing mechanism will be described.

FIG. 10 is a plan view showing the sliding door opening / closing mechanism when the sliding door is completely opened, and FIG. 11 is a perspective view showing a part of the sliding door opening / closing mechanism of FIG. FIG. 12 is a plan view showing a state in which the locking between the swing stopper 70 and the check swing 74 has been released by the knocking 42 and the first and second arms 64 and 66 can be rotated slightly. FIG.
It is a perspective view showing the state where the 1st and 2nd arms 64 and 66 started to rotate. FIG. 14 shows the first and second arms 64,
FIG. 15 is a plan view showing a state in which the slide door has been closed after rotation of 66 has completed, and FIG. 15 is a perspective view showing a part of FIG. 6 in an enlarged manner. In these drawings, the same components as those in FIGS. 1 to 9 are denoted by the same reference numerals.

In the slide door opening / closing mechanism 30 of the first embodiment described above, as clearly shown in FIG. 7, when the slide door is closed, the first and second arms 64,
66 overlap each other in the vehicle width direction. On the other hand, in the slide door opening / closing mechanism 90 of the second embodiment, FIG.
When the sliding door is closed as shown in FIG.
The second arms 64 and 66 overlap each other in the vertical direction (the height direction of the vehicle). To achieve such a configuration, the sliding door opening / closing mechanism 90 of the second embodiment is used.
In the structure of the slide member 100 and the fixing member 120,
The configuration of the slide member 50 and the fixing member 80 of the slide door opening / closing mechanism 30 of the first embodiment is different.

The sliding member 100 of the sliding door opening / closing mechanism 90 includes one end 64 of the first and second arms 64 and 66.
a, 66a are provided with a fixing plate 110 rotatably fixed. The fixing plate 110 includes three parallel side walls 112, 114, and 116 that are bent at substantially right angles from the vertical wall 52 toward the vehicle interior. One end 64a of the first arm 64 is rotatably fixed to a portion on the vehicle rear side in the space between the side walls 112 and 114. Further, one end 66a of the second arm 66 is rotatably fixed to a portion on the vehicle front side in the space between the side walls 114 and 116. The side wall 1
A check swing 74 is formed on the upper surface of the twelve.
Also, although not clearly shown in FIG.
In the structure 20, the other ends 64 b, 66 b of the first and second arms 64, 66 are vertically rotatably fixed in a rotatable manner in accordance with the structure of the fixing plate 110.

The movements of the knocking 42, the swing stopper 70, the check swing 74, the knock slide 44, the slide stopper 60, and the plate stopper 76 when the sliding door is opened and closed are shown in FIGS.
As shown in FIGS. 5A and 5B, the sliding door opening / closing mechanism 30 of the first embodiment is the same.

As described above, the sliding door opening / closing mechanism 90
In this embodiment, the first and second arms 64 and 66 are arranged so as to overlap each other in the up-down direction. Therefore, as shown in FIGS. 10 and 11, one end 64 of the first and second arms 64 and 66 are provided.
It is not necessary to shift the positions of a and 66a in the vehicle width direction. Similarly, the other ends 64 of the first and second arms 64 and 66 are also provided.
It is not necessary to shift the positions of b and 66b in the vehicle width direction. Therefore, as can be seen by comparing FIGS. 1 and 10, the thickness of the slide member 100 and the fixed member 120 is compared with the thickness of the slide member 50 and the fixed member 80 of the slide door opening / closing mechanism 30 of the first embodiment. It can be thin. As a result, the protrusion of the sliding door opening / closing mechanism 90 into the cab is reduced, and the space can be further reduced.

[0045]

As described above, in the first sliding door opening / closing mechanism of the present invention, the rail is provided with the slide prohibiting member and the rotation permitting member for prohibiting and permitting the sliding and turning of the slide door in cooperation with the holding member. Since it is formed, it can be compact and small in size.

Here, the holding member is a rotatable rod-shaped swing stopper urged in a predetermined rotation direction, and a bar-shaped check swing which locks the swing stopper to prevent the sliding door from turning. And the swing permitting member releases the locking between the swing stopper and the check swing to allow the slide door to swing, and the two rod-shaped swing stoppers and the check swing are provided. Since the turning of the slide door is prohibited by the locking of the members, and the locking is released only by the turning permission member formed on the rail, a more compact sliding door opening / closing mechanism can be obtained.

Further, the holding member includes a slide stopper urged in a predetermined urging direction, and a substantially fan-shaped plate stopper for prohibiting the slide stopper from moving in a direction opposite to the urging direction. And the slide prohibiting member is configured to prohibit the slide door from sliding by contacting the slide stopper and biasing the slide stopper in the opposite direction as described above. The sliding door is inhibited by only locking the two members, and the sliding of the sliding door is inhibited only by contacting the sliding inhibiting member formed on the rail with the sliding stopper. An opening and closing mechanism is obtained.

In the second sliding door opening / closing mechanism of the present invention, the knocking slide and the knocking formed on the rail and the check swing and the swing stopper cooperate to open and close the sliding door. The mechanism is compact and the size can be small.

Here, when the at least one arm comprises two arms extending in parallel with each other, the sliding door is more firmly supported by the two arms, so that the sliding door can be more smoothly. Can be opened and closed.

Further, when the two arms are arranged so as to be overlapped with each other in the vertical direction when the slide door is closed, the amount by which the slide door opening / closing mechanism protrudes into the vehicle is reduced. Further space saving can be achieved.
