Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous sliding door in which a plurality of sliding doors arranged in parallel run in conjunction.

[0002]

2. Description of the Related Art Conventionally, as a continuous sliding door in which a plurality of sliding doors arranged in parallel run in cooperation, for example, there is one disclosed in Japanese Utility Model Registration No. 2511022. That is, in the above-mentioned continuous sliding door, metal engaging members are disposed at the front and rear ends or one end of the upper end of the hanging sliding door. Thus, the plurality of sliding doors can be opened and closed in conjunction with each other by engaging the engaging members of the adjacent sliding doors with each other.

[0003]

However, the conventional sliding door has the following problems. That is, the engaging tool in the continuous sliding door is provided only at the upper end of the hanging sliding door. Therefore, if the sliding door is opened and closed vigorously, a large force is applied to the engaging member, which may cause breakage. Although the cushioning material is fixed to the engaging member, the impact cannot be sufficiently absorbed because the main body itself is made of metal.

The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a continuous sliding door having a hook which can sufficiently absorb an impact.

[0005]

According to a first aspect of the present invention, a plurality of sliding doors are arranged in parallel, and when one of the sliding doors is moved in a closing direction, another sliding door adjacent thereto is also interlocked. The sliding doors are configured to run in a direction in which the sliding doors are closed, and each of the sliding doors has, on an opposing surface facing a sliding door adjacent to each other, a hook that comes into contact with each other when the sliding doors are pulled in the closing direction. The hook body comprises a bottom portion fixed to the sliding door, a contact portion erected on the contact side at the bottom portion, and a shock absorbing portion connected to the non-contact side of the bottom portion from the top of the contact portion. The abutting part and the shock absorbing part are made of a deformable soft material, and the sliding door has a hollow inside.

What is most notable in the present invention is that the hook has a hollow interior, and the contact portion and the shock absorbing portion are made of a deformable soft material.

Next, the function and effect of the present invention will be described.
Since the inside of the hook is hollow and the abutting portion and the impact absorbing portion are made of a deformable soft material, the impact when the abutting portions abut each other can be sufficiently absorbed. That is, when closing the continuous sliding doors, the contact portions of the hooks in each sliding door abut each other. At this time, the contact part and the shock absorbing part of the hooking body are deformed, and absorb the shock at the time of contact.

When the sliding door is slightly warped due to long-term use, the top of the hanging member comes into contact with the adjacent sliding door. However, since the abutting portion and the shock absorbing portion are made of a soft material, the hooking portion is made of a soft material. The body is easily deformed and there is no danger of scratching the design surface of the sliding door.

When the sliding door is closed, the hooks of the adjacent sliding doors have an average of 5 to 20 mm in the traveling direction.
It is preferable that they are arranged so as to have the following interval. Thereby, when closing the above-mentioned consecutive sliding doors, it is the last sliding door in the closing direction (hereinafter referred to as the last sliding door).
Can be prevented from moving.

That is, when closing the continuous sliding doors, the leading sliding doors (hereinafter referred to as front sliding doors) are moved in the closing direction, so that the sliding doors adjacent to each other run sequentially in conjunction with each other. When the tip of the leading sliding door reaches one of the vertical frames in the door frame, the last sliding door remains at the original position, thereby realizing the fully closed state.

However, when the leading sliding door is driven to reach one of the vertical frames of the door frame, the other linked sliding doors are further moved due to inertial force. Therefore, the second sliding door from the last moves in the same way. At this time, when the second sliding door from the last hooks and moves the last sliding door, the other end of the door frame is opened. In order to prevent this, it is preferable that the above-mentioned hooks of the adjacent sliding doors are provided with the above-mentioned interval when the continuous sliding door is fully closed. As a result, the last sliding door stops before the last sliding door is pulled, and the fully closed state can be maintained.

If the distance is less than 5 mm, the last sliding door may move. On the other hand, when the interval exceeds 20 mm, in the fully closed state of the continuous sliding doors, the frame portions of adjacent sliding doors may not be aligned, and the appearance may be impaired.

As described above, according to the present invention, it is possible to provide a continuous sliding door having a hook that can sufficiently absorb an impact.

Next, it is preferable that the bottom of the hook is made of a hard material. Thus, the hook can be accurately fixed to the sliding door.

Next, as in the invention according to claim 3, the hard material in the hook is a hard plastic,
Preferably, the soft material is a soft plastic. In this case, since the material is easily available and the molding is easy, it is possible to obtain a sliding door with a low manufacturing cost.

Next, as in the fourth aspect of the present invention, the contact portion and the shock absorbing portion of the hook are formed integrally, and the contact portion and the bottom portion and the shock absorbing portion and the bottom portion are formed integrally. It is preferable that they are joined to each other. This can prevent the hooks from being excessively deformed when the hooks come into contact with each other.

Next, as in the fifth aspect of the present invention, the contact portion and the shock absorbing portion of the hook are integrally formed, and the bottom and the contact portion are joined together. On the other hand, the bottom and the end of the shock absorbing portion are not joined, and when the hook is fixed to the sliding door, the end of the shock absorbing portion is fixed to the bottom and the sliding door by a fixture. It is preferable that it is fixed to.

This makes it easy to form the hook,
At the time of use, similarly to the invention described in claim 4, the hook can be reliably absorbed without the deformation of the hooking body too much.

Next, as in the sixth aspect of the present invention, it is preferable that the hook is provided along the entire length of the sliding door in the height direction of the sliding door. As a result, the hooks come into contact with each other in a large area, so that the impact can be sufficiently absorbed. Further, even when the sliding door slightly warps, there is no possibility that the hooks will not come into contact with each other. In addition, the gap between the sliding doors is closed by the hanging body, so that it is possible to prevent invasion of cold air, hot air, or light leakage.
