Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mirror stopper for mounting a mirror on a wall surface.

[0002]

2. Description of the Related Art Generally, a mirror is attached to a wall surface by a lower holder and an upper mirror stopper, and the mirror stopper is slidable up and down with respect to the mirror (a long hole provided in the mirror stopper). It is fixed to the wall surface with a set screw through, and by loosening this set screw, the mirror stopper slides in the range of the long hole.). However, with the above-mentioned conventional technology, although there is no problem at the beginning of installation, if the mirror surface is repeatedly wiped with a rag during long-term use, the set screw will loosen and the mirror stopper will move easily, and a slight external force (the mirror surface can be moved up and down with a rag). There is a risk that it will be lifted when wiped on. The mirror stop gradually moves away from the top edge of the mirror and becomes unsightly.

A technique for solving this problem is disclosed in Japanese Utility Model Laid-Open No. 3-129361 (mirror fixture). According to FIG. 1 of this publication, a hook member (corresponding to a mirror stopper) 10 The mirror locking portion 10a is formed on the upper side of the and the biasing member fixing portion 12 is formed on the lower side, and the hook member 10 is loosely fixed to the wall surface with the screw 3 through the elongated hole 11 provided therein, and moved to this screw 3. By locking the ring 23 at one end of the prevention biasing member (torsion spring) 20 and inserting the other end of the movement prevention biasing member 20 into the biasing member fixing portion 12 of the hook member 10,
The hook member 10 is elastically downward. To attach the mirror M to the wall surface W with the mirror fixing tool, as shown in FIG. 3, the hook member 10 is picked up and lifted, the mirror M is set on the wall surface W, and the grasped hand is released (with movement prevention means). The hook member 10 descends by the elastic force of the biasing member 20 and is locked to the upper edge of the mirror M).

[0004]

In order to prevent the hook member 10 from being lifted up by a slight external force, such a mirror fixture has a movement preventing biasing force for elastically pulling the hook member 10 downward. The elastic force of the member 20 is required to be large. On the other hand, in order to mount the mirror M on the wall surface W, the lifted hook member 10 is locked to the upper edge of the mirror, and when the picked hand is released, the hook member 10 moves preventing biasing member 20. The vibrating force of violently hits the upper edge of the mirror M. For this reason, the edge of the mirror M may be chipped if a large impact is applied, so it is preferable that the elastic force of the movement preventing biasing member 20 is not too large. However, in order to prevent lifting, the elastic force of the movement preventing biasing member 20 cannot be reduced. In order to make up for this, it is necessary to take care such as slowly lowering the hook member 10 so as not to give an impact to the upper edge of the mirror M during the hooking work, and the work is troublesome.

Therefore, an object of the present invention is (1) when attaching a mirror to a wall, it is not necessary to take care not to give an impact to the edge of the mirror, and (2) the movable member is held by a slight external force. There is no fear of going up and the upper edge of the mirror can be stopped securely.

[0006]

In order to achieve the above object, the invention according to claim 1 is a fixing member screwed to a wall surface and provided with a spring receiving portion and a vertical guide groove on the front surface, and the vertical member. A movable member that is guided only in vertical movement in a guide groove, and has a spring hooking portion provided on the front surface, a hook portion that is provided above the movable member and that locks to the upper edge of the mirror, and the spring receiving portion. And a spring for elastically lowering a movable member that is hooked to the spring hooking portion and is fitted to the fixed member so as to move only vertically, and the elastic force of the spring is changed. An elastic force changing mechanism is attached between the fixing member and the spring. Since the elastic force of the spring changes, the speed at which the hook portion descends can be limited. Therefore, it is possible to reduce the impact on the mirror at the moment when the hook portion contacts the upper edge of the mirror. Moreover, since the elastic force of the spring can be changed, the elastic force for lifting the movable member can be set to a large value. For this reason,
There is no fear that the movable member will be lifted by a slight external force.

According to a second aspect of the present invention, the spring is formed of a wire or a strip in a left-right symmetrical and substantially inverted V shape, and both ends of the spring are hooked on the spring receiving portion provided on the left and right sides of the fixing member. And, the central side is hung on the spring hooking portion having the center in the left-right direction of the movable member, and further, on both end sides of the spring, a first descending action portion opened downward in a substantially V shape,
By forming a second lowering action portion having a substantially C-shaped opening angle larger than that of the first lowering action portion on the upper side of the first lowering action portion, a lower position where the hook portion is locked to the upper edge of the mirror. When the hook is open to the left and right and the hook portion is at an upper position separated from the upper edge of the mirror, it is squeezed to the center in the left-right direction by engagement with the spring receiving portion, and the elastic force changing mechanism is , The first
-It is characterized in that it is configured by the second descending action portion and the spring receiving portion. Since the opening angle of the second descending action portion is larger than that of the first descending action portion, the downward elastic force is also larger. When the movable member is lowered, the spring first descends while the first lowering action portion having a smaller elastic force engages with the spring receiving portion, and then the second lowering action portion having a greater elastic force is received by the spring receiving portion. Descends while engaging with the section. Therefore, the hook portion descends at a relatively low speed in the first predetermined time, and then descends at a higher speed than this to contact the upper edge of the mirror. Therefore, even if the hook descends at a high speed, the acceleration time is short, and the final speed at the moment of contact with the upper edge of the mirror is relatively low. This weakens the impact at the moment when the hook contacts the upper edge of the mirror. Further, when the mirror is attached to the wall surface with the mirror stopper, since the second lowering action portion having a large elastic force is engaged with the spring receiving portion, the elastic force for lifting the movable member is large. Therefore, there is no fear that the movable member will be lifted by a slight external force.

According to a third aspect of the present invention, arc-shaped third descending action portions projecting outward in the left-right direction of the spring are formed on both ends of the spring and above the second descending action portion. And Since the arc-shaped third action portion is formed in the spring, the final speed at the moment of contact with the upper edge of the mirror becomes further low. Therefore, the impact on the mirror at the moment when the hook portion contacts the upper edge of the mirror is further weakened.

According to a fourth aspect of the present invention, the spring is formed of a wire or strip in a left-right symmetrical substantially inverted V shape and curved in a side view, and both ends of the spring are provided on the left and right sides of the fixing member. It is hung on the spring receiving part and hung on the spring hanging part having a center side at the center of the movable member in the left-right direction, and further, the lowering action part opened downward in a substantially V shape on both end sides. And the elastic force change mechanism is constituted by the descending action portion and the spring receiving portion. When the movable member is lowered, the descending action portion that is curved in side view is engaged with the spring receiving portion, and is lowered while being deformed into a flat shape in side view. For this reason, the descending speed of the spring is limited and the spring descends, so that the impact of the hook portion contacting the upper edge of the mirror is weakened.
Further, when the mirror is attached to the wall surface with the mirror stopper, the portion of the descending action portion engaged with the spring receiving portion is deformed into a flat shape in a side view, so that the elastic force against lifting of the movable member is increased. large. Therefore, there is no fear that the movable member will be lifted by a slight external force.

According to a fifth aspect of the present invention, the spring is formed of a wire material or a band material in a substantially symmetrical V-shape, and both ends of the spring are hooked on the spring receiving portion on the left and right sides of the fixing member. And, the center side is hung on the spring hooking portion having the center in the left-right direction of the movable member, and further, the lowering action portions opened downward in a substantially V shape are formed on the both end sides. When the hook is in the lower position where it is locked to the upper edge of the mirror, it opens to the left and right, and when the hook is in the upper position, which is off the upper edge of the mirror, it engages with the spring bearing to center in the left-right direction. In addition, a coating having a predetermined frictional resistance is applied to the surface of the spring, and the elastic force changing mechanism is
It is characterized in that it is constituted by the descending action portion of the coated spring and the spring receiving portion. The elastic force of the spring can be changed by the frictional force between the descending action portion and the spring receiving portion of the spring whose surface has a predetermined frictional resistance, so that the spring has a simple shape. No
It is possible to limit the speed at which the hook portion descends. Further, since the frictional force between the spring and the spring hook portion acts on the lifting of the movable member, the resistance against the lifting of the movable member is further increased.

According to a sixth aspect of the present invention, there is provided a fixing member which is screwed to the wall surface and provided with a spring receiving portion and a vertical guide groove on the front surface, and the vertical guide groove which guides only vertical movement.
A movable member in which a spring hooking portion is erected on the front surface, a hook portion provided on an upper portion of the movable member and locked to an upper edge of the mirror, the spring receiver and the spring hooking portion are hooked, In a mirror stopper consisting of a spring that resiliently urges a movable member downwardly fitted to a fixed member, in the hook portion, a convex portion is provided on a surface facing the upper end surface of the mirror, It is characterized in that the convex portion abuts on the upper end surface of the mirror substantially at the center in the thickness direction or at the rear of the center. When the movable member descends by the elastic force of the spring, the convex part hits the upper end surface of the mirror,
The hook does not hit the top edge of the mirror. Further, since the convex portion abuts on the upper end surface of the mirror substantially at the center in the thickness direction or on the rear portion from the center, the impact applied to the corner portion on the front surface side of the mirror is further prevented.

The invention according to claim 7 is characterized in that the convex portion is formed integrally with the hook portion. Since the convex portion is formed integrally with the hook portion, the convex portion can be formed at the same time when the movable member is formed.

The invention according to claim 8 is characterized in that the convex portion is formed of a cushion material and is fixed to the hook portion. Since the protrusion made of cushion material is fixed to the hook, the impact when the protrusion hits the upper end surface of the mirror is small.

The fixing member 11 has one convex portion 23 on its mounting surface for mounting on the wall surface 2 (see FIG. 1). That is, on the back surface of the lower horizontal portion 12c, a hemispherical convex portion 23 is integrally formed at the center in the left-right direction and between the screw hole 15 and the pressing arm 16.

The movable member 31 includes a plate-shaped movable main body 32,
A pair of left and right leg portions 33 extending below the movable body 32,

Spring hooking portion 36 provided at the center of the direction and near the hook portion 35
And is integrally bent and formed from a plate material such as a steel plate. Since the movable member 31 is guided so that it can move up and down only, the leg portions 33, 33 are fitted in the vertical guide grooves 13, 13.

The pressure contact portions 34 and 34 are locked to the holding portions 17 and 17 by frictional force, and the protruding surfaces are hemispherical. The press contact portions 34, 34 are formed by, for example, embossing. The combination of the holding portion 17 of the fixed member 11 and the pressure contact portion 34 of the movable member 31 constitutes a lock mechanism that locks the hook portion 35 before the mirror is attached so as not to descend.

The spring 41 is formed of a wire material having elasticity (for example, a piano wire) or a strip material in a substantially symmetrical V-shape (a shape similar to an Ω shape) which is symmetrical. That is, the spring 41 has a substantially hairpin shape with the central portion 42 facing downward, and the end portions 43, 43 at the lowermost end and the first descending action portion (inclined portion) at the upper end of the end portions 43, 43 on both end sides. Four
4, 44 and second descending action portions (inclined portions) 45, 45 above the first descending action portions 44, 44 are integrally formed.

The terminal portions 43, 43 have a folded shape, the first lowering action portions 44, 44 have a shape that is opened obliquely downward in a substantially C-shape, and the second lowering action portions 45, 45 have an oblique downward direction. The opening angle is larger than that of the first lowering action portion, and the opening angle is larger than the first lowering action portion. These terminal portions 43 and the first and second
The descending action portions 44 and 45 are formed in the left-right direction of the spring 41. The spring 41 is elastically urged in the direction in which the first lowering action portions 44, 44 are separated from each other and the second lowering action portions 45, 45 are separated from each other.

Both ends (first and second descending action portions 44 and 45) of the spring 41 are hooked on the spring receiving portions 14 and 14 of the fixed member 11, and the central portion 42 is bent to the spring hooking portion 36 of the movable member 31.
By being hung on the movable member 31, the movable member 31 fitted in the fixed member 11 so that it can move only up and down is repelled downward. Thus, the spring 41 opens to the left and right when the hook portion 35 is in the lower position where it is locked to the upper edge of the mirror 1, and when the hook portion 35 is in the upper position that is off the upper edge of the mirror 1. Spring receiving part 1
It is configured to be narrowed to the center in the left-right direction by engaging with 4, 14.

Therefore, the elastic force of the spring 41 is such that when the second lowering action portions 45, 45 are engaged with the spring receiving portions 14, 14, the first lowering action portions 44, 44 are spring-loaded. Receiver 1
It changes so as to become larger than the state in which it is engaged with 4, 4. The configuration including the spring receiving portion 14 and the first and second descending action portions 44 and 45 constitutes an elastic force changing mechanism that changes the elastic force of the spring 41.

FIG. 3 is an enlarged sectional view taken along line 3-3 of FIG.
The lower receiver 4 has a substantially J-shaped cross section, and the back surface has a set screw 5
Is attached to the wall surface 2 to sandwich and receive the lower edge of the mirror 1 and the cushion 6. The lower receiving member 4 is integrally formed by bending a plate material such as a steel plate, and is elastically deformable in the front-rear direction (left-right direction in this figure). On the back surface of the lower receiver 4,
Hemispherical convex portions 7, 7 are integrally formed at two upper and lower positions sandwiching the set screw 5.

On the other hand, the fixing member 11 of the mirror stopper 10 is attached to the wall surface 2 with a set screw 21. The upper edge of the mirror 1 is locked by the hook portion 35 of the movable member 31, and the pressing arm 16
Is pressed by the mirror 1 and elastically deformed toward the wall surface 2 side.

4 (a) and 4 (b) are a structural view and an operational view of the hook portion (first embodiment) of the movable member according to the present invention,
(A) shows a state where the hook part is off the upper edge of the mirror, and (b)
Shows a state where the hook portion is locked to the upper edge of the mirror. The hook portion 35 is provided with a convex portion 38 on a surface facing the upper end surface 1a of the mirror 1, and the convex portion 38 is provided substantially at the center of the upper end surface 1a of the mirror 1 in the thickness direction (left-right direction in this figure) or at the rear of the center. It comes into contact. That is, the convex portion 38 is integrally formed by penetrating to the left and right of the hook portion 35 (front and rear in this figure), and its cross-sectional shape is a downward semicircular shape. As shown in (b), the single convex portion 38 is offset from the center of the plate thickness of the mirror 1 to the rear portion by the dimension S.

Next, the operation of the elastic force changing mechanism will be described with reference to FIG. FIGS. 5A to 5C are explanatory views of the operation of the elastic force changing mechanism (first embodiment) according to the present invention. (A) is
The state in which the spring is in the uppermost position is shown, which corresponds to the time when the hook portion 35 starts descending from the upper position. (B) shows the state where the spring is in the middle of descending. (C) shows the state in which the spring is at the lowest position, and corresponds to the case where the hook portion 35 is at the lower position where it is locked to the upper edge of the mirror 1.

In the state of (a), the first lowering action parts 44, 4
4 is engaged with the spring receiving portions 14 and 14, the spring 41
Is narrowed to the center in the left-right direction. In this state, the central portion 42 expands by its own elastic force, and the horizontal component force at this time causes the first lowering action portions 44, 44 to move outward along the spring receiving portions 14, 14. Therefore, although the spring 41 descends,
Relatively low speed due to small downward elastic force.

During the lowering of the spring 41, as shown in (b), the first lowering action portion 44,
The shift from 44 to the engagement with the second lowering action parts 45, 45 is performed. The second lowering action parts 45, 45 are the first lowering action part 44,
Since the opening angle is larger than 44, the horizontal component force is also large,
Large downward elasticity. Therefore, the second lowering action portion 4
5 and 45 rapidly move outward along the spring bearings 14 and 14. Therefore, although the spring 41 continues to descend, it has a relatively high elastic force in the downward direction, so that the speed is relatively high.

After that, the spring 41, as shown in FIG.
The second lowering action parts 45, 45 with respect to the spring receiving parts 14, 14.
And the lowering is stopped. in this way,
Regarding the elastic force of the spring 41, when the second lowering action portions 45, 45 are engaged with the spring receiving portions 14, 14, the first lowering action portions 44, 44 act on the spring receiving portions 14, 14. It changes so as to be larger than the engaged state.

Next, an assembling procedure of the mounting structure of the mirror 1 by the lower receiving member 4 and the mirror stopper 10 having the above-mentioned structure will be described. First, as shown in FIG. 1, the lower receiving member 4 is attached to the wall surface 2, and then the mirror stopper 10 is aligned with the wall surface 2 and attached. Next, the procedure for attaching the mirror stopper 10 will be described. 6 and 7 are explanatory views of the operation of the mirror stopper (first embodiment) according to the present invention.

As shown in FIG. 6, the mirror stopper 10 has the leg portions 3 of the movable member 31 in the vertical guide grooves 13, 13 of the fixed member 11.
3, 33 are inserted, then the central portion 42 of the spring 41 is hung on the spring hooking portion 36, and thereafter, both ends of the spring 41 (the upper part of the second lowering action portion 45) are pressed by the spring receiving portion while compressing both ends. 1
It is assembled by hanging on 4. The assembled mirror stopper 10 is attached to the wall surface 2 with a set screw 21 (see FIG. 3).

Then, when the hook portion 35 of the movable member 31 is picked up and lifted, the movable member 31 is raised to the upper position shown in FIG. At the same time, both ends of the spring 41 move inward along the spring receiving portions 14, 14. In this upper position, the movable member 31 is locked by the frictional force due to the pressure contact between the holding portion 17 and the pressure contact portion 34, and does not descend even if the grasped hand is released.

When the hook portion 35 of the movable member 31 is pushed down after the upper edge of the mirror 1 is aligned, the holding portion 17 and the leg portions 33, 33 are elastically deformed in opposite directions. Therefore, the holding portion 17 and the pressure contact portion 34 are unlocked by the frictional force. Therefore, the movable member 31 is pulled down by the elastic force of the spring 41. That is, as shown in FIG. 6, the central portion 42 of the spring 41 is
Spreads by its own elastic force, and the horizontal component force at this time causes both ends to move outward along the spring receiving portions 14, 14. Therefore, the spring 41 pulls down the movable member 31. Therefore,
The movable member 31 is automatically pulled down, and the hook portion 35 is locked to the upper edge of the mirror 1. This completes the assembly work.

By the way, from the state shown in FIG.
When 1 is lowered, the hook portion 35 descends at a relatively low speed for a predetermined time at the beginning of descent (the time when the first descending action portions 44, 44 descend along the spring receiving portions 14, 14), and thereafter, Next predetermined time (the second descending action parts 45, 45 are
4 and 14), and descends at a relatively high speed, and finally contacts the upper edge of the mirror 1. Therefore, the hook 3
Since the acceleration time is short even if 5 descends at a high speed, the final speed at the moment of contacting the upper edge of the mirror 1 is relatively low. Therefore, the impact on the mirror 1 at the moment when the hook portion 35 contacts the upper edge of the mirror 1 is weak.

In this way, since the impact on the mirror 1 is weak, it is not necessary to take care not to impact the upper edge of the mirror 1 when mounting the mirror on the wall 1. Moreover, since the elastic force of the spring 41 can be changed, the elastic force (resistive force) against the lifting of the movable member 31 can be set to a large value. That is, the mirror 1 shown in FIG.
When the movable member 31 is attached to the movable member 31, the second lowering action parts 45, 45 having a large elastic force are engaged with the spring receiving parts 14, 14, so that the elastic force for lifting the movable member 31 is large.
Therefore, the movable member 31 is not likely to be lifted by a slight external force, and the upper edge of the mirror 1 can be reliably stopped.

On the other hand, as shown in FIG.
As shown in (b), the convex portion 38 causes the upper end surface 1 of the mirror 1 to move when the lower part is separated from the upper edge of the mirror 1 by the elastic force of the spring.
a. For this reason, the hook portion 35 is the corner portion 1 of the upper edge of the mirror 1.
Never hit b, 1c. Therefore, when mounting the mirror 1 on the wall surface, it is not necessary to take care not to give an impact to the corners 1b and 1c at the upper edge of the mirror 1. Further, since the convex portion 38 abuts on the upper end surface 1a of the mirror 1 substantially at the center in the thickness direction or at the rear of the center, it is possible to further prevent the corner portion 1b on the front surface side of the mirror 1 from being impacted.

In the second embodiment, the arc-shaped third descending action parts 46, which protrude outward in the left-right direction of the spring 41, are provided on both ends of the spring 41 and above the second descending action parts 45, 45.
It is characterized in that 46 is integrally formed. The configuration including the spring receiving portion 14, the spring hooking portion 36, and the first, second, and third lowering action portions 44, 45, and 46 constitutes an elastic force changing mechanism that changes the elastic force of the spring 41. To do.

Next, the operation of the second embodiment will be described with reference to FIGS.
3 will be described. FIG. 13 is an operation explanatory view of the mirror stopper (second embodiment) according to the present invention. With the hook 35 of the movable member 31 raised to the upper position shown in FIG.
When the hook portion 35 is pushed down after the upper edges of the
The frictional force between the press contact portion 34 and the pressure contact portion 34 is released. Therefore, the movable member 31 is pulled down by the elastic force of the spring 41,
As shown in FIG. 12A, the hook portion 35 is locked to the upper edge of the mirror 1.

In this case, the spring 41 includes the spring receiving portions 14, 14
In contrast, the engagement relationship moves in the order of the first lowering action parts 44, 44 → the second lowering action parts 45, 45 → the third lowering action parts 46, 46, and finally the lower end of the central portion 42 is engaged. To do. For this reason, in the spring 41, the second lowering action portions 45, 45 have the spring receiving portion 1
4 and 14 rapidly descends, but thereafter, the arc-shaped third descending action portions 46, 46 projecting outward are provided to the spring receiving portion 1.
Since it engages with Nos. 4 and 14, the descending speed becomes low again.
Therefore, the final speed at which the hook portion 35 contacts the upper edge of the mirror 1 is relatively low. Then, the impact of contacting the hook portion 35 with the upper edge of the mirror 1 becomes weaker.

Therefore, when mounting the mirror 1 on the wall surface 2, it is not necessary to take care not to give an impact to the upper edge of the mirror 1. In addition, the arc-shaped protrusion height of the third lowering action portions 46, 46 can be set to be large, and the elastic force (resistive force) against the lifting of the movable member 31 can be set to be large. Therefore, there is no fear that the movable member 31 will be lifted by a slight external force, and the upper edge of the mirror 1 can be stopped more reliably.

Next, a third embodiment will be described with reference to FIGS. 14 and 15. The same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. FIG.
(A), (b) is a mirror stopper according to the present invention (third embodiment)
2A and 2B are configuration diagrams of the above, wherein FIG. In the third embodiment, the lowermost end portions 43, 43 and the end portions 43, 4 are provided on both end sides of the spring 41 having a curved side view.
It is characterized in that only the first lowering action parts (lowering action parts) 44, 44 on the upper part of 3 are formed.

Specifically, the spring 41 extends from both lower ends of the central portion 42 to the upper portions of the terminal portions 43, 43 for the first lowering action portion 4.
4, 44, and the first descending action portions 44, 44 are curved (curled) in the left-right direction. Further, as shown by the imaginary line in (b), the spring 41 is curved in a side view (curved gently from the upper end of the central portion 42 to the lower end of the first lowering action portion 44) curved to the front side (left side in this figure). Shape).

The spring 41 is squeezed rearward (to the right in this figure) by the lowering action portion 44 being hooked on the L-shaped spring receiving portion 14 in plan view, as shown by the solid line in (b). It is set in a slightly flattened state. The spring receiving portions 14, 14 and the first lowering action portion 4 combined in this way
The configuration including 4, 44 constitutes an elastic force change mechanism for changing the elastic force of the spring 41.

Next, the operation of the third embodiment will be described with reference to FIGS.
It will be described based on 5. 15 (a) and 15 (b) are explanatory views of the operation of the mirror stopper (third embodiment) according to the present invention.
(A) shows the front and (b) shows the side. Movable member 3
When the hook portion 35 of No. 1 is raised to the upper position shown in FIG. 15 (a) and the hook portion 35 is pushed down after aligning the upper edge of the mirror 1, the holding portion 17 and the pressure contact portion 34 are caused by frictional force. The lock comes off. Therefore, the movable member 31 is pulled down by the elastic force of the spring 41, and the hook portion 35 is moved to the mirror 1 as shown in FIG.
Is locked to the upper edge of the.

In this case, as shown in FIG. 15B, the spring receiving portion 14 is in the first position with the hook portion 35 raised to the upper position.
It engages with the lower end of the descending action portion 44. For this reason, the spring 41 is not squeezed by the spring receiving portion 14, and thus is substantially curved in a side view. From this state, the central portion 42 expands in the left-right direction in FIG. 15A by its own elastic force, and the horizontal component force at this time causes the first lowering action portions 44, 44 to move into the spring receiving portions 14, 1.
Move outward along 4 Therefore, the spring 41 descends.

With the lowering of the first lowering action portion 44, the first lowering action portion 44 is squeezed from the lower portion to the upper portion by the spring receiving portion 14, so that the first lowering action portion 44 descends while deforming into a flat shape in a side view. For this reason, the spring 41 descends with its descending speed limited, so that the impact of the hook 35 abutting the upper edge of the mirror 1 can be weakened. Therefore, when mounting the mirror 1 on the wall surface 2, the mirror 1
You don't have to be careful not to hit the top edge of
Installation workability is improved.

Further, when the mirror 1 is attached to the wall surface 2 by the mirror stopper 10, the first lowering action portion 44 has the spring receiving portion 14
Since the portion engaged with is deformed into a flat shape in a side view, the elastic force (resistive force) against the lifting of the movable member 31 is large. Therefore, there is no fear that the movable member 31 will be lifted by a slight external force, and the upper edge of the mirror 1 can be reliably stopped.
According to the third embodiment, the elastic force of the spring 41 can be changed with a simple configuration in which the spring 41 is curved in a side view.

Next, a fourth embodiment will be described with reference to FIGS. The same components as those in the third embodiment are designated by the same reference numerals and the description thereof will be omitted. FIG. 16 is a front view of a mirror stopper (fourth embodiment) according to the present invention. 4th
In the embodiment, the spring 41 of the third embodiment shown in FIG. 14 is linear in a side view. That is, the spring 41 does not have a curved shape in a side view. And the spring 41
Is characterized in that a coating having a predetermined frictional resistance is applied to the surface thereof, and the coating is applied by plating or resin coating, for example. The spring receiving parts 14, 1 combined in this way
4 and the first lowering action portions 44, 44 constitute an elastic force change mechanism that changes the elastic force of the spring 41.

Next, the operation of the fourth embodiment will be described with reference to FIGS.
7 will be described. FIG. 17 is an operation explanatory view of the mirror stopper (third embodiment) according to the present invention. With the hook 35 of the movable member 31 raised to the upper position shown in FIG.
When the hook portion 35 is pushed down after the upper edges of the
The lock between the pressure contact portion 34 and the pressure contact portion 34 is released by frictional force. Therefore, the movable member 31 is pulled down by the elastic force of the spring 41,
As shown in FIG. 16, the hook 35 is locked to the upper edge of the mirror 1.

In this case, since the surface of the spring 41 is coated with a frictional resistance, the sliding frictional resistance with the spring receiving portions 14, 14 is large. Therefore, when the movable member 31 is lowered, the hook portion 35 descends at a relatively low speed and comes into contact with the upper edge of the mirror 1. Therefore, the final speed at which the hook portion 35 contacts the upper edge of the mirror 1 is relatively low. Then, the impact of contacting the hook portion 35 with the upper edge of the mirror 1 becomes weaker.

As described above, when the mirror 1 is mounted on the wall surface 2, it is not necessary to take care not to give an impact to the upper edge of the mirror 1. Further, even when the movable member 31 is lifted, the frictional force between the spring 41 and the spring receiving portions 14 and 14 acts, so that the elastic force (resistive force) against the lifting of the movable member 31.
Will be even larger. Therefore, the movable member 31 is not likely to be lifted by a slight external force, and the upper edge of the mirror 1 can be reliably stopped. According to the fourth embodiment, although the spring 41 has a simple shape, the speed at which the hook portion 35 descends can be limited.

In the first, second, third and fourth embodiments, the convex portions 38, 38 of the movable member 31 on the hook portion 35 are formed.
The presence or absence of A to 38D is arbitrary. By providing both the elastic force changing mechanism and the convex portions 38, 38A to 38D, the mirror 1
The impact of contacting the hook portion 35 with the upper edge of the upper edge becomes even weaker.

Further, the hooked portion 35 has convex portions 38, 38A-38.
The mirror stopper 10 having the configuration including D may not have the elastic force changing mechanism. For example, in the structure of the fourth embodiment shown in FIG. 16 described above, the spring 41 whose surface is not coated can be used. In this case, the convex portions 38, 38A to 38D act so as not to give an impact to the upper edge of the mirror 1,
The elastic force of the first lowering action portions 44, 44 of the spring 41 acts so that the movable member 31 is not lifted.

[0060]

Since the present invention is configured as described above, it has the following effects. According to the first aspect of the present invention, the elastic force changing mechanism for changing the elastic force of the spring is provided between the fixing member and the spring, so that the elastic force of the spring changes. You can limit the speed at which you do. Therefore, it is possible to reduce the impact on the mirror at the moment when the hook portion contacts the upper edge of the mirror. Therefore, when the mirror is mounted on the wall surface, it is not necessary to take care not to give an impact to the upper edge of the mirror, and the workability of mounting is enhanced. Moreover, since the elastic force of the spring can be changed, the elastic force for lifting the movable member can be set to a large value. Therefore, there is no fear that the movable member will be lifted by a slight external force, and the upper edge of the mirror can be reliably stopped.

According to the second aspect of the present invention, the substantially V-shaped spring is hooked on the spring receiving portions having both ends on the left and right sides of the fixing member.
Further, the center side of the spring is hooked on a spring hooking portion which is provided at the center of the movable member in the left-right direction, and further, a first lowering action portion opened downward in a substantially C-shape on both end sides of the spring, and the first lowering action portion. A second lowering action portion having a substantially C-shaped opening angle larger than that of the first lowering action portion is formed at the upper part of the first lowering action portion, and the elastic force changing mechanism is provided with the first and second lowering action portions, the spring hooking portion, and the spring receiving portion. With the above configuration, the opening angle of the second descending action portion is larger than that of the first descending action portion, so that the downward elastic force is also increased. Then, when the movable member is lowered, the spring first descends while the first lowering action portion having a smaller elastic force engages with the spring receiving portion, and then the second lowering action portion having a larger elastic force is generated. It moves down while engaging with the spring receiving portion. Therefore, the hook portion descends at a relatively low speed in the first predetermined time, and then descends at a higher speed than this to contact the upper edge of the mirror. Therefore, even if the hook descends at a high speed, the acceleration time is short, and the final speed at the moment of contact with the upper edge of the mirror is relatively low. This can reduce the impact at the moment when the hook contacts the upper edge of the mirror. Therefore, when attaching the mirror to the wall, it is not necessary to take care not to give an impact to the upper edge of the mirror, and the mounting workability is enhanced. Also,
In the state where the mirror is attached to the wall surface with the mirror stopper, the second lowering action portion having a large elastic force is engaged with the spring receiving portion,
Large elastic force for lifting the movable member. Therefore, there is no fear that the movable member will be lifted by a slight external force, and the upper edge of the mirror can be reliably stopped. In addition, the spring first
-The elastic force of the spring can be changed with a simple structure in which only the second acting portion is formed.

According to the third aspect of the present invention, since the arc-shaped third descending action portion projecting outward in the left-right direction of the spring is formed on both end sides of the spring and above the second descending action portion, the upper part of the mirror The final speed at the moment of contact with the edge can be made lower. Therefore, it is possible to further reduce the impact on the mirror at the moment when the hook portion contacts the upper edge of the mirror.

According to the fourth aspect of the present invention, both ends of the spring having a substantially inverted V shape and a curved shape in side view are hooked on the spring receiving portions which are provided on the left and right sides of the fixing member, and further, the both ends are substantially downwardly extended. By forming the descending action portion opened in a letter shape and configuring the elastic force change mechanism by the descending action portion and the spring receiving portion, when the movable member is lowered, the descending action portion having a curved side view is formed. By engaging with the spring receiving portion, it descends while deforming into a flat shape in a side view.
For this reason, the spring descends with the descending speed limited,
It is possible to reduce the impact of the hook portion contacting the upper edge of the mirror.
Therefore, when attaching the mirror to the wall, it is not necessary to take care not to give an impact to the upper edge of the mirror, and the mounting workability is enhanced. Further, when the mirror is attached to the wall surface with the mirror stopper, the portion of the descending action portion engaged with the spring receiving portion is deformed into a flat shape in a side view, so that the elastic force against lifting of the movable member is increased. large. Therefore, there is no fear that the movable member will be lifted by a slight external force, and the upper edge of the mirror can be reliably stopped. Further, the elastic force of the spring can be changed with a simple configuration in which the spring is curved in a side view.

According to a fifth aspect of the present invention, the elastic force changing mechanism is composed of a lowering action portion and a spring receiving portion of a spring whose surface is coated with a film having a predetermined friction resistance. Since the elastic force of the spring can be changed by the frictional force with the spring receiving portion, the speed at which the hook portion descends can be limited even though the spring has a simple shape. Further, since the frictional force between the spring and the spring hook portion acts on the lifting of the movable member, the resistance against the lifting of the movable member is further increased.

According to a sixth aspect of the present invention, the hook portion of the movable member is provided with a convex portion on a surface facing the upper end surface of the mirror, and the convex portion is provided substantially at the center in the thickness direction of the upper end surface of the mirror or at the rear of the center. When the movable member descends by the elastic force of the spring due to the contact, the convex portion abuts on the upper end surface of the mirror, so that the hook portion does not abut the corner portion of the upper edge of the mirror. Therefore, when attaching the mirror to the wall, it is not necessary to take care not to give an impact to the corner of the upper edge of the mirror, and the workability of mounting is improved. In addition, since the convex portion abuts on the upper end surface of the mirror substantially at the center in the thickness direction or at the rear of the center, it is possible to further prevent the impact from being applied to the corner portion on the front surface side of the mirror.

According to the seventh aspect of the present invention, since the convex portion is formed integrally with the hook portion, the convex portion can be formed at the same time when the movable member is formed, the structure is simplified, and the productivity is increased.

According to the eighth aspect of the present invention, since the convex portion formed of the cushion material is fixed to the hook portion, the impact when the convex portion hits the upper end surface of the mirror is small.
