[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock-absorbing member mainly used for crime prevention and used for a door guard for limiting an opening angle of a door.

[0002]

2. Description of the Related Art A door guard mainly used for crime prevention has a structure in which a hook protruding from a door and an arm which is pivotally supported by a building body and engages with the hook are provided.

The official use of this door guard is to securely close the door and then engage the arm with the hook. However, the door guard is often used for a hotel room door or a door of an apartment house. In particular, since hotel room doors are often equipped with automatic locks, when there is heavy traffic such as when cleaning the inside of a room, knock down the arm before closing the door and put the door guard between the door and the building body. In some cases, it is used to prevent the door from being automatically locked. In such a usage, the arm made of a metal such as stainless steel or cast iron may come into contact with the surface of the door during the closing operation and damage the door. In order to prevent the door from being damaged, there is a door guard having a structure in which a cushioning material is provided at a portion corresponding to the door of the arm as shown in Japanese Utility Model Laid-Open No. 4-103976.

However, such a door guard adopts a special structure for providing a cushioning material, and a cushioning member for a door guard as disclosed in Japanese Utility Model Laid-Open No. 4-103976 is used as a conventional product that does not employ such a structure. Can not be applied. Therefore, in order to prevent the door from being damaged, it is necessary to replace the existing door guard with one having the above-mentioned structure, which has a disadvantage of increasing costs.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to obtain a cushioning member that can be used for an existing door guard.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a pair of attachment portions each attached to a parallel portion of a door guard arm, the attachment portions are integrally connected to each other, and the attachment portions are arranged outside the movement trajectory of the door guard hook. And a connecting portion.

[0007]

The cushioning member of the present invention mounts a pair of mounting portions on the parallel portion of the door guard. For this mounting portion, mounting means such as holding the arm or bonding to the arm can be applied.
In the case of a structure in which the arm is clamped, the arm can be slid on the arm to adjust the buffer so that it comes into contact with the door, and can be freely removed.

When the door guard is used, the door guard is turned to the operating position with the hook disposed in the slit between the arm parallel portions. When the door is opened in this state, the spherical projection of the hook slides in the slit to the end of the arm, so that the door can be opened at a small angle. When the hook slides, the connecting portion of the buffer member is located outside the movement locus of the hook, so that the connecting portion does not interfere with the hook. If the door guard is used after the door is opened, and the door is closed, a hook is arranged between the door and the opening of the building door to prevent the automatic lock of the door from being closed. Hits the door, thereby preventing the door from being damaged. The contact portion to the door in this state may have a shape such that a part of the attachment portion other than the connecting portion is protruded so as to be a contact portion to the door.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A door guard to which a cushioning member according to an embodiment of the present invention is applied will be described with reference to FIGS. 2 and 5 to 8. FIG.

FIG. 5 shows a closed state of the door 12, and the door 12 is opened in the direction of arrow A as shown in FIG.
In the figure, (IN) indicates an indoor room and (OUT) indicates an outdoor room.
As shown in FIG. 2, a bracket 16 has a plate-like base member 1 attached to a building body 14 to which the door 12 is attached.
6A, and a pin 18 is attached to the bracket 16.
The arm 22 is supported by the shaft.

The arm 22 has a substantially U-shape. Both ends 23, which are the tips of the parallel portions, are pivotal support portions for the bracket 16, and the central loop portion corresponds to a hook 24 fixed to the door 12. ing. The hook 24 is fixed to the indoor side of the door 12 via a plate-shaped base member 24B, and is bent in the longitudinal direction toward the bracket 16 when the door is closed. The tip of the hook 24 has a spherical projection 24A.
Is formed and arranged in both ends 23 of the arm with the door closed. Therefore, as shown in FIG. 6, when the arm 22 is rotated around the pin 18 and tilted (in the direction of arrow B), the hook 24 is disposed between the arms 22, and the spherical projection 24 A moves through the slit of the arm 22 by opening the door 12. Slide,
The opening angle of the door 12 is maintained at the state shown in FIG.

The operation of the door guard will be described with reference to FIG.
Is a closed state of the door 12, and the arm 22 is rotated in the direction of arrow B as shown in FIG.
The state overturned is the use state. Here, when the door 12 is opened, as shown in FIG.
Engagement with the second slit limits the opening angle of the door 12. Therefore, the occupants in the room can see the outside of the room through the gap between the door 12 and the building body 14. However, this gap is not large enough for a person to pass.

FIG. 8 shows the arm 22 before the door 12 is closed.
When the door 12 moves to the closing operation, the arm 22 comes into contact with the surface of the door 12. At this time, if the arm 22 made of metal directly contacts the door 12, the door 12 is damaged. Therefore, in order to prevent the door from being damaged, the arm 22 has a cushioning member 28.
Is attached.

As shown in FIG. 1, the cushioning member 28 according to the present embodiment includes a main body 30, legs 32, and auxiliary legs 34 made of nylon.
It is composed of

The main body 30 comprises a pair of flat portions 30A arranged on both sides and a curved central portion 30B. The flat portion 30A is provided on the bottom surface of the arm 22 of the door guard (by rotating the arm 22 and inserting it into the slit of the arm 22). The center portion 30B is a connecting portion of the flat portion 30A, and the hook 24 is inserted into the slit of the arm 22. When the hook 24 is slid in the state in which is disposed, the escape portion is formed so that the spherical projection 24A of the hook 24 can pass through, that is, the escape portion is arranged outside the movement locus of the spherical projection 24A.

A pair of legs 32 are provided from both ends of the main body 30 so as to project substantially perpendicularly from the central portion 30B in a direction opposite to the bending direction of the central portion 30B. Also leg 3
The second end 32A is bent toward the center of the slit so as to be substantially parallel to the flat portion 30A of the main body 30.

A pair of auxiliary leg portions 34 corresponding to the leg portions 32 are provided from the attachment portion of the curved central portion 30B of the main body 30. The auxiliary leg portion 34 is substantially parallel to the leg portion 32. More specifically, the substantially central portion of the auxiliary leg portion 34 is slightly curved so as to form a chevron toward the center of the slit. Along the shape. An end 34A of the auxiliary leg 34 is bent toward the leg 32 so as to be substantially parallel to the flat portion 30A of the main body 30.

The distance between the flat portion 30A of the main body 30 and the end 32A of the leg 32 and the end 34A of the auxiliary leg 34 is equal to or slightly smaller than the height of the arm 22 of the door guard. The distance between the leg 32 and the auxiliary leg 34 is
It is the same as or slightly smaller than the width of 2. These flat portion 30A, leg portion 32, end portion 32A of leg portion 32, auxiliary leg portion 3
4. The end 34A of the auxiliary leg 34 is a mounting portion for mounting the buffer member 28 to the arm 22. These mounting portions are provided by the arm 2
2, but when attaching to the arm 22 by bonding or the like, other portions may be deleted except the flat portion 30A or the like used for bonding.

Next, the operation of the cushioning member 28 according to this embodiment will be described. As shown in FIG. 4, the arm 2 is inserted into a space defined by the leg 32, the flat portion 30A of the main body 30, and the auxiliary leg 34.
2 in this embodiment, the flat portion 30 of the main body 30 is inserted in this embodiment.
A and end 32A of leg 32 and end 34 of auxiliary leg 34
Since the distance between the arm 22 and the distance between the leg 32 and the auxiliary leg 34 is equal to or slightly smaller than the height and width of the arm 22, the cushioning member 28 is fixed to the arm 22 with an adhesive or the like. Instead, the arm 22 can be clamped. Therefore, when used without being fixed to the arm 22, the cushioning member 28 is detachable, and can be adjusted by sliding on the arm 22 so that the central portion 30 </ b> B of the main body 30 contacts the door 12.

Also, when the arm 22 is rotated as shown in FIG. 6 to dispose the hook 24 in the slit of the arm 22 and the door is opened as shown in FIG. Since the central portion 30B of the main body 30 is curved as described above, the spherical projection 24A of the hook 24 does not prevent the inside of the slit from sliding.

Next, as shown in FIG. 8, when the arm 22 is used after the door 12 is opened to prevent the door 12 from being closed, the central portion 3 of the cushioning member 28
As 0B hits the door 12 and prevents the door 12 from closing,
The door 12 by the arm 22 directly hitting the door 12
Can be prevented from being damaged. In addition to applying the central portion 30B to the door 12, a projection may be provided on another portion such as the flat portion 30A so as to apply to the door 12.

In this embodiment, the central portion 30B of the main body 30 is curved.
Any configuration that does not hinder the sliding of the spherical projection 24A is not particularly limited to the above configuration. FIG.
In the use state, the arm 22 does not rotate in the counterclockwise direction than the illustrated state. However, if the arm 22 can rotate until it hits the building body 14, a part of the buffer member 28 is moved to the building body 14. It may be possible to prevent the building main body 14 from being damaged by touching.

When the cushioning member according to the present invention is applied to an arm having a circular or elliptical cross section, the main body 30, the legs 32, and the auxiliary legs 34 except for the central portion 30B form one outer periphery of the arm. It becomes the composition which covers a part.

The material used for the cushioning member according to the present invention is not limited to nylon as long as it has appropriate strength.

[0025]

[Effects of the Invention] The present invention has the above configuration,
The door guard itself does not require a special structure and can be used for an existing door guard. Therefore, it is not necessary to replace the entire door guard for preventing the door from being damaged, and the cost can be reduced. When the cushioning member is used without being fixed to the arm, it is detachable. Even if the cushioning member has deteriorated due to use, it is sufficient to replace only the cushioning member with a new one. Simplification can be achieved.
