DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double door used for a storage or a locker.

[0002]

2. Description of the Related Art Conventionally, in this type of double-opening door, for example, a flat-shaped door stop protruding toward the left door is formed at the rear end of the anti-hanging side surface of the right door. Such a door stop is formed by projecting a rear plate made of sheet metal forming a door laterally from an anti-hanging side surface portion formed by a front plate made of sheet metal. Are generally coated with Furthermore, in recent years, the door which is a problem in the metal door stop is formed by forming the door stop into a plate shape using a hard synthetic resin and integrally molding a soft material on an edge portion on the opposite side of the suspension base. It is also known that the collision sound generated when the vehicle is closed is lowered.

[0003]

By the way, in the above-mentioned structure, the door stop protrudes to the side of the door.
When closing the door, the door may collide with the side surface of the other door opposite to the suspension base. However, since the above-mentioned door stop is formed from a sheet metal rear plate forming the door or is a flat plate formed of a synthetic resin, it cannot withstand such unexpected collision in terms of strength. It could not be cut, often deformed or damaged, and then ceased to function as a stop and the door did not close properly.

An object of the present invention is to solve such a problem.

[0005]

In order to achieve the above object, the present invention takes the following measures. That is, in the double-opening door according to the present invention, in the double-opening door provided with a door stop in the vicinity of the opposite side of the other door of one door facing the other side of the door, the opposite side of the original side of each door Has inclined surfaces that are separated from each other in the back direction, and the door stop is attached to the inclined surface of the one door, and when both doors are closed, the surface becomes parallel to the inclined surface of the other door. It is characterized by comprising a triangular prism-shaped body having:

In order to simplify the mounting structure of the triangular prism, one door has a vertical groove in the vertical direction near the opposite side surface of the anti-hanging base on the back surface, and the triangular prism has the one vertical groove. A rear plate that is substantially flush with the back surface of the door, a mounting tongue formed substantially perpendicular to one edge of the rear plate and fitted into the vertical groove, and the other edge of the rear plate at the other edge. It is preferable to include an inclined side plate parallel to the inclined surface of the door, and a front plate continuous to the inclined side plate and substantially flush with the surface of the one door. In such a triangular prism-shaped body, in order to mitigate the collision sound when closing the door, the inclined side plate, when closed, can contact the inclined surface of the other door in the vertical direction. Those having an article are preferred. Further, in manufacturing, the rear plate, the mounting tongue, the inclined side plate and the front plate may be integrally molded with a hard synthetic resin, and the ridge may be integrally molded with the rear plate and the inclined side plate with a soft synthetic resin. preferable.

[0007]

With such a construction, since the door stop is a triangular prism-shaped body, substantially three sides receive an impact applied thereto. In other words, since the cross-sectional shape is triangular, an extremely large force is required to deform it by an external force. Therefore, in a collision that occurs when the door is normally opened and closed, the impact is not so large, and therefore, it is possible to prevent the door from being closed due to deformation or breakage of the door stop.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

The embodiment shown in FIG. 1 is a case where the present invention is applied to a storage L which is hinged to a main body 1.

The main body 1 is composed of a side plate 11, a rear plate connecting the side plates 11, a top plate 12, and a bottom plate. The front edges 11a of the left and right side plates 11 are hinged to an angle range of 90 ° or more. The door 2 is hinged so that it can be opened.

The door 2 includes a left door 2A and a right door 2B. As shown in FIGS. 2 and 3, the doors 2A and 2B comprise a front plate 21 and a rear plate 22 made of sheet metal, and are symmetrical. Shaped. Then, when the left door 2A and the right door 2B are closed, the anti-hanging side surface portion 24 formed by the front plate 21 in which the left door 2A and the right door 2B face each other is in the rear direction, that is, the main body 1 is closed. Including inclined surfaces 24a which are separated from each other in the inner direction,
A triangular prism 3A, which is a door stop 3, which will be described later, is mounted on the inclined surface 24a. The back plate 22 has both side portions formed on the step portion 23 by bending, and the side edge 22 a of the back plate 22 is opposite to the side surface 24 of the front plate 21.
It is in contact with the back surface of the front plate 21 in the vicinity. This step 23
The front plate 21 is attached to a step portion 23b at a position separated from the side surface portion 23a by the thickness dimension of the mounting tongue 3s of the triangular prism body 3.
The bent side edge portions 21a of the door 2 are in contact with each other to form vertical vertical grooves 4 on the back surface of the door 2.

The triangular prism 3 has the same length as the door 2 and has a rear plate 31 substantially flush with the back surface of the left door 2A, that is, the surface of the rear plate 22, and one of the rear plates 31. Edge 31a
A tongue 32 formed substantially perpendicular to the vertical groove 4 and fitted into the vertical groove 4, an inclined side plate 33 which is parallel to the inclined surface 24a of the right door 2B on the other edge 31b of the rear plate 31, and an inclined side plate. The front plate 34 is continuous with the front plate 21 and is substantially flush with the surface of the left door 2A, that is, the surface of the front plate 21. In order to mitigate the collision sound when the door 2 is closed, a decorative plate 5 for covering the inclined surface 24a of the right door 2B when closed is provided substantially at the center in the width direction of the inclined side plate 33. A vertical ridge 33a is formed which can abut against the ridge 33a. Similarly, a protruding ridge 31c extending in the vertical direction that contacts the upper and lower frames of the main body 1 is formed in a portion near the other edge 31b of the rear plate 31. The triangular prism 3 is an extruded material made of a synthetic resin, and the rear plate 31, the mounting tongues 32, the inclined side plate 33, and the front plate 34 are integrally formed of a hard material, and the protrusions 33a are formed of a soft material. And is integrally formed with the rear plate 31 and the inclined side plate 33.

The rear plate 31 and the inclined side plate 33 are formed at an angle of about 45 °, and a front plate 34 is formed so as to be substantially parallel to the rear plate 31. That is, the rear plate 3
A substantially hollow triangular prism is formed with an isosceles triangle 35 having an apex angle of about 90 ° and a cross section formed by the inclined side plate 33 with 1 as a base. With the triangular prism as a core, a structure for mounting is formed by the rear plate 31, the mounting tongues 32, and the front plate 34. Therefore, the front plate 34 which also serves as a decorative plate
Are slightly biased toward the rear plate 31 side from the parallel state, and are elastically deformed when the triangular prism-shaped body 3 is mounted, and come into close contact with the front plate 21 of the left door 2A in a state of clamping the left door 2A. And, at one end 35a and the top 35b of the base of the isosceles triangle 35, a claw 36 is formed which comes into contact with the inclined surface 24 of the left door 2A.

The decorative plate 5 attached to the right door 2B is made of a hard synthetic resin and has a substantially C-shaped cross section, similarly to the portion of the triangular prism 3A except for the protrusions 31c and 33a.
In the vertical groove 4 of the right door 2B. And
The right door 2B is covered so as to sandwich the portion from the vicinity of the anti-hanging base side surface portion 24 of the front plate 21 to the vertical groove 4. In the above-described configuration, the triangular prism-shaped body 3A having a door stop of 3 is attached by sliding the attachment claw 32 on the folded portion 21b of the front plate 21 constituting a part of the back surface of the left door 2A. The entire triangular prism body 3A is the anti-hanging side surface 2 of the left door 2A.
It is performed by moving in four directions. Then, the mounting claw 32 is guided to the vertical groove 4 and is fitted into the vertical groove 4 to complete the mounting of the triangular prism 3A. In this mounting operation, the rear plate 31 and the front plate 34 are slightly deviated inward from the parallel state.
It is necessary to increase the distance between the front plate 21 and the front plate 34. However, the mounting claw 32 is brought into contact with the inclined surface 24a of the left door 2A, and the front plate 34 is similarly brought into contact with the surface of the front plate 21 of the left door 2A, thereby forming a triangle. When the columnar body 3A is pressed, the mounting claw 32 is guided on the inclined surface 24a, and the triangular columnar body 3A is elastically deformed, the space between the rear plate 31 and the front plate 34 naturally expands, and the mounting claw 32 is folded back. It reaches the part 21b. Therefore, the mounting work becomes easy.
The triangular prism-shaped body 3A attached to the left door 2A has a mounting claw 32.
Is fitted into the vertical groove 4 and the portion of the front plate 34 that is continuous with the inclined side plate 33 is in contact with the anti-hanging side surface portion 24 of the left door 2A, so that movement in the center direction of the left door 2A is prohibited. I have. The rear plate 31 and the inclined side plate 33 form a triangular prism with respect to the inclined surface 24a by the two claw portions 36.

As described above, when the left door 2A and the right door 2B are closed, the inclined side plate 33 becomes parallel to the inclined surface 24a of the right door 2B at the door stop 3 made of the triangular prism-shaped body 3A, The ridges 31c of the rear plate 34 contact the upper and lower frames of the main body 1, and the ridges 33a of the inclined side plate 33 are connected to the right door 2B.
Abuts on the decorative plate 5 on the inclined surface 24a. Therefore,
The collision noise generated when the door 2 is closed can be reduced. In addition, since the triangular prism portion of the triangular prism-shaped body 3A has a door stop of substantially 3, it has sufficient rigidity against external force from any direction, and the strength can be improved. Further, by forming the triangular prism within the range of the thickness of the door 2, sufficient strength is exhibited, so that it is not necessary to increase the thickness of the door 2, and it is possible to make the door 2 compact and lightweight.

The present invention is not limited to the embodiment described above. For example, the triangular prism 103A is
As shown in FIG. 4, the rear plate 131 may have a shape protruding toward the back surface of the door 2 at the triangular prism portion 135a. Further, a plurality of ridges 133 are integrally formed on the inclined side plate 133.
a is molded.

In addition, the configuration of each section is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

[0018]

According to the present invention, as described in detail above, since the door stop has a triangular cross-sectional shape, the door stop has high rigidity. Even if the original side surface portion collides, it is possible to prevent the original side surface portion from being deformed or damaged, and thus it is possible to prevent a failure such as the door not closing.
