Abstract

(57) [Summary] [Purpose] Even if the door guard hits the outside surface of the door, the door will not be damaged. [Structure] The arm 22 of the door guard is partially provided with cushioning rubber 28 on both outer peripheries, so that even if the arm 22 is folded down and the door 12 is closed, the cushioning rubber 28 hits the door 12 and the bracket 16. , there is no damage to the door 12.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is mainly used for crime prevention and relates to door guards that limit the opening angle of the door. do.

0002

[Conventional technology]

A hook protruding from the door is used as a door guard mainly used for crime prevention. There is a door guard with a structure that is pivoted to the building body and has an arm that engages with the hook. Ru.

0003 With this door guard, the user can rotate the arm after the door is closed. When the loop part of the door comes into contact with the hook, the hook will be arm-armed when the door is opened. The opening angle of the door is limited to a predetermined range by engaging with the loop portion. For this reason, indoor living Persons can visually check the outside conditions through the narrow gap where the door is open; This creates an insufficient gap to pass through.

0004 This type of door guard ensures that the arm engages the hook after the door is closed. The official method of use is to fold the arm, but before closing the door, fold the arm If you stop it while it is in contact with the supporting bracket, this arm will stop during the closing operation. It may hit the door surface and damage the door.

[0005] In particular, the conventional arm has a stopper to prevent it from rotating too much towards the door when the door is closed. is installed on the shaft support, but due to the improper use mentioned above, the arm may be pushed away from the door. The stopper may become deformed or the arm may break due to the rotational force.

[0006]

[Problem that the idea aims to solve]

This invention takes the above facts into consideration, and prevents the arm of the door guard from being accidentally operated before the door is closed. The purpose is to obtain a door guard that will not cause damage to the door even if .

[0007]

[Means to solve the problem]

This invention is pivoted to the building body via a bracket to the hook protruding from the door. A door guard that engages with an arm to limit the opening angle of the door, the door guard having a A feature is that a cushioning material is provided on the side in the part corresponding to the door and the part corresponding to the bracket. It is said that

[0008]

[Effect]

For this reason, with this invention, if the arm is inadvertently collapsed before the door is completely closed, However, since a cushioning material is provided around the outer circumference of the arm, the arm is It will come into contact with the bracket and door through. Therefore, the door closes with force. This can also prevent the door surface from being scratched.

[0009]

【Example】

1 to 6 show examples of door guards to which the present invention is applied.

0010 FIG. 1 shows the door 12 in the closed state, and the door 12 is opened in the direction of arrow A as shown in FIG. A release action is performed. In the figure, (IN) indicates indoors, and (OUT) indicates outdoors. this A bracket 16 is a plate-shaped base member on the building body 14 to which the door 12 is attached. 16A and pin 18 to this bracket 16 as shown in FIG. Therefore, the arm 22 is pivotally supported.

[0011] This arm 22 is approximately U-shaped, and the vicinity of both ends thereof are widened portions 23 and are The central loop part serves as a pivot support to the butt 16, and the central loop part serves as a flap fixed to the door 12. It corresponds to Tsuk24. The hook 24 is attached to the door 12 via the plate-like base member 24B. The bracket is fixed to the interior side of the door, and its longitudinal direction bends in the 16 direction when the door is closed. It is curved. In addition, a spherical projection 24A is formed at the tip of the hook 24 to close the door. It is placed into the arm widening part 23 in this state. Therefore, as shown in Figure 2, arm 22 is connected to pin 1. When it rotates 8 times and falls down (in the direction of arrow B), the hook 24 is placed between the arms 22. When the door 12 is opened, the spherical protrusion 24A moves against the door 12 of the arm 22. It is arranged on the opposite side to maintain the opening angle of the door 12 in the state shown in FIG.

0012 Note that the conventional arm 22 is designed to prevent further rotation in the direction of arrow B in the state shown in FIG. A protruding stopper S (see diagonal lines in Fig. 2) is provided on a part of the bracket 16. However, in the present invention, this stopper S is not provided, and the arrow It can be rotated in the B direction and comes into contact with the base member 16A of the bracket 16 as shown in FIG. It is said that access is possible.

[0013] As shown in detail in FIG. 6, the arm 22 in this embodiment has loose parts on both sides. A shock rubber 28 is fixed. This cushioning rubber 28 is attached to the door 1 on the outer surface of the arm 22. 2 and the bracket 16 through the rivet 28A. The rivet 28A is fixed or glued to the arm 22, but this rivet 28A is connected to the rubber 28. It may also be a rubber material formed on the body. These cushioning rubbers 28 are as shown in FIG. Before the door 12 is closed, the door 12 and the bracket 16 are They are designed to touch each other. As shown by the imaginary line in FIG. A similar cushioning rubber 28B is provided near the tip of the loop portion of the arm 22, and the arm is placed in the state shown in Fig. 2. It also serves as a buffer between the door 12 and the door 12 when the door 12 is further rotated in the direction of arrow B. good.

[0014] In this embodiment configured as described above, FIG. 1 shows the door 12 in a closed state, and FIG. 2 shows the closed state of the door 12. Rotate the arm 22 in the direction of arrow B as shown to cover the loop portion onto the hook 24. The state in which it is used is the state in which it is used. When the door 12 is opened, the ball will appear as shown in FIG. The protrusion 24A engages with the loop portion of the arm 22 to limit the opening angle of the door 12. . Therefore, occupants inside the room can access the outside through the gap between the door 12 and the building body 14. You can see what's going on. However, this gap is not large enough for a person to pass through. be. Since the cushioning rubber 28 is not provided inside the loop of the arm 22, the foot There is no problem even if the lock 24 slides. Also, when rotating in the direction of arrow B as shown in Figure 2, There is no cushioning rubber 28 on the arm 22 at the part of the hook 24 that contacts the base member 24B. Therefore, the arm 22 rebounds in the direction opposite to the arrow B direction and returns to the spherical protrusion 24A. There is no possibility that the engagement will be incomplete.

[0015] FIG. 4 shows the state in which the arm 22 is folded down before closing the door 12. When the door 12 moves to a closing operation, the arm 22 comes into contact with the surface of the door 12. But this In the embodiment, since the cushioning rubber 28 is formed on the outer periphery of the arm 22, the arm 2 Since the metal part of 2 does not come into direct contact with the door 12, damage to the door 12 can be prevented. Ru. Further, in this state, the arm 22 is connected to the building body 14 on the opposite side via the cushioning rubber 28. Since it corresponds to the bracket 16 instead of the There's nothing wrong with that.

[0016] In addition, conventionally, a large closing force of the door 12 is applied to the arm 22 in the usage state shown in FIG. When this happens, the stopper S (see Fig. 2) may be deformed, and this deformation may cause the arm 22 to become However, with the present invention, the This is prevented.

[0017] Furthermore, if a cushioning rubber 28B is attached to the tip of the arm 22 as shown in FIG. If the arm 22 is carelessly knocked down before the door is closed, the door closing action may cause the arm 22 to Even when the longitudinal direction of the door is perpendicular to the door plane, the cushioning rubber 28B covers the door surface. Protect.

[0018]

[Effect of the idea]

Since this invention has the above configuration, even if the arm is inadvertently knocked down before the door is closed, the door will not close. It has an excellent effect of preventing damage to the arm and breaking of the arm.
