Description

[Detailed description of the invention] The present invention is a doorstop for a double-opening door in which a doorstop plate is provided on one door, and the door is closed by placing the other door against the doorstop plate. Regarding the improvement of the device, more specifically, when the door is closed, the impact of contact between the door stop plate and the other door applies a load to the door surface on the side where the door stop plate is attached, causing distortion on the surface. In addition to preventing this and muffling the impact noise when closing without using a complicated structure, manufacturing can be simplified by making the joining part of the double-opening door the same on the left and right sides,
The present invention relates to the provision of a door stop device that has a good appearance and is sturdy.

Conventionally, as shown in FIG. 1, the joining part 2a of the double-opening door 1a in a storage partition is not bent in the same way on the left and right sides, and a door stop plate is placed on the inside of one of the bent plates 2b in the joining part 2a. Because 9a was spot welded, the manufacturing process could not be simplified, and the spot weld marks were exposed at the end of the joining part 2a, making it unsightly.Furthermore, the door stop plate 9a was easily damaged by the impact of contact between the door stop plate 9a and other doors. As a result, there have been problems such as distortion of the door surface on the side where the door stop plate is attached and generation of noise.

This invention was devised in view of the above-mentioned problems.
The gist of this is that both double-opening doors are of the same type, and the mounting positional relationship between the front plate and the back plate is set to be larger than the thickness of the legs for attaching the door stop plate. The point is that the plate is fixed to the back plate without contacting the front plate.

The details of the present invention will be explained based on the embodiment shown in FIG. 2 of the accompanying drawings.

Here, A is a storage partition, 1 is a door, 2 is a matching section, 4 is a front plate, 6 is an interior material, 7 is a back plate, and 9 is a door stop plate. The door 1 of the present invention is usually composed of a front plate 4, a back plate 7, and an interior material 6, and a door stop plate 9 is attached to either one of the doors 1 which opens on both sides. As shown in FIG. 2, which is a cross section, the surface plate 4 has both side edges bent 3 inward to extend a length corresponding to the thickness of the door, and extends inward parallel to the surface plate 4. In the example shown in the figure, the opposing bent edges 5, 5 are formed by further providing a turn at the tip, and between the opposing bent edges 5, 5, a door stop having an L-shaped cross section is provided on both sides. Both side walls 8, 8 are sized so that the plate 9 can be positioned with a gap larger than the thickness of the leg 10 of the plate 9, and at a height corresponding to the thickness of the door.
The back plate 7 formed by bending the interior material 6 is placed between the both side walls.
The door 1 is constructed by attaching it to the back side of the surface plate 4 in a state in which it is installed inside, and the two doors 1, 1 are arranged in a straight line.
The leg portion 10 of the doorstop plate 9 is attached to the outer surface of the side wall 8 of the back plate 7 of the door 1 on the left side in the figure.
is fixed at a position where the door stop plate 9 does not come into contact with the surface plate 4 and the bent edge 5, that is, at a position close to the door stop plate 9 but at a position that is securely spaced apart. Note that 11 indicated by a dashed line in the figure is a partition plate to which the ends of the double-opening doors 1, 1 are attached.

However, if the device for double-opening doors of the storage partition of the present invention is used, the door 1 of the same type can be used instead of having different configurations for the left and right doors as a joining part, as in the conventional double-opening door shown in Fig. 1. If a certain front plate 4 and back plate 7 are manufactured, they can be used in common for both double-opening doors, and similarly, as in the conventional example, the door stop plate 9a can be spot welded later to expose the welding marks. If the door 1 is fixed to the back plate 7 by welding or the like in advance when assembling the door 1, no unsightly welding marks will appear on the outer surface of the door. Furthermore, when one door 1 and the door stop plate 9 come into contact when closing the door, since the door stop plate 9 and the front plate 4 are not in direct contact, the impact force at the time of contact is also applied to the top plate 4. is not transmitted directly, and there is no risk of causing harmful distortion or deformation of the surface plate 4. Therefore, it is possible to attach cushioning material to the door stop plate 9 or the bent edge 5, or to add reinforcement material to the door stop plate 9 or the bent edge 5. There is no need to attach a rod or the like, and in the same way, the doorstop plate 9 is separated from the front plate 4 and fixed only to the back plate 7, and the inside of the back plate 7 is filled with interior material 6. Therefore, the bent edge 5 and the door stop plate 9 at the time of stop
Noises such as collision sounds with the door stop plate 9 are transmitted to the back plate 7 via the door stop plate 9, and are absorbed by the interior material 6.

According to the above-described device for double-swinging doors for storage partitions of the present invention, the doors on both sides of the joint part of the double-swinging doors can be shared by the same type of door, making manufacturing easy and simple, and reducing costs. are also connected,
Furthermore, the installation positional relationship between the front plate and the back plate with interior materials inside is set to be larger than the thickness of the legs for attaching the door stop plate, so that the door stop plate does not come into contact with the front plate. Since it is fixed to the back plate, it is possible to prevent the load from being applied to the door surface on the side where the door stop plate is attached due to the contact impact when the door is closed and cause distortion on that surface, and also to reduce the impact noise when closing. This makes it possible to provide a door contact device for double-opening doors that is extremely suitable for use.
