Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an interlocking sliding door in which three sliding doors are opened and closed in conjunction with each other.
[0002]
[Prior art]
Conventionally, when an outer sliding door is opened and closed, an intermediate sliding door and an inner sliding door are opened and closed in conjunction with each other via an interlocking piece, for example, as disclosed in Japanese Unexamined Patent Publication No. 6-22487. In this known sliding door, the latching portion protruding from the inner door contacts the latching portion of the intermediate door, and the latching portion protruding from the intermediate door contacts the latching portion of the outer door, and each door is interlocked. It has a structure that opens and closes. However, in such a structure, a latching part or a latching part must be formed in advance on the door itself, and a generally used sliding door cannot be used as it is.
[0003]
Another known example is disclosed in Japanese Patent Application No. 11-229712. In this known example, a door interlocking body that moves together with the door body is attached in the vicinity of both front and rear ends of the intermediate door body, and an engaged receiving portion that receives the guide pivot of the side door body is provided on the door interlocking body. The side door body and the intermediate door body are interlocked with each other, and basically has the same concept as that of the structure of the actual open / closed No. 6-22487. Also in this latter case, the door interlocking body must be assembled so as to move together with the intermediate door body, and generally used sliding doors cannot be used as they are.
[0004]
[Problems to be solved by the invention]
Therefore, the present invention is a sliding door comprising three doors that run along at least three dedicated upper rails laid in parallel, and without any modification to the sliding door structure, The main purpose is to provide an interlocking sliding door that is inexpensive and easy to construct, so that it can be used as an interlocking sliding door simply by fitting a simple slider.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention takes the following technical means. That is, in the interlocking sliding door according to the present invention, the three upper rails 4a, 4b, and 4c arranged in parallel and adjacent to each other through the sliding bodies 1a, 1b, 2a, 2b, 3a, and 3b, respectively. The sliding body 1a, 1b, 2a, 2b, 3a, 3b includes an outer door 1, an intermediate door 2 and an inner door 3 that are slidably mounted. A pair of left and right sliders 5 and 6 are slidably mounted on the rail 4b between the sliding bodies 2a and 2b before and after the intermediate door 2 and between the door upper end surface and the rail 4b. 6 is provided with contact pieces 5a, 5b, 6a, 6b extending to the transition path of the outer door 1 and the inner door 3, and the left side when all the doors 1, 2, 3 are fully opened to the left. The main body of the slider 5 abuts against the sliding body 2a of the intermediate door 2 and The contact piece 5a is disposed so as to contact the left side of the sliding body 1a of the outer door 1 and the other contact piece 5b is positioned to the right side of the sliding body 3a of the inner door 3, and the main body portion of the right slider 6 is in the middle. The abutting piece 6b abuts on the right side of the sliding body 3b of the inner door 3 and the other abutting piece 6a is located on the left side of the sliding body 1b of the outer door 1 while abutting on the sliding body 2b of the door 2. The sliders 5 and 6 are provided with slide portions 5c and 6c that slide on the rail 4b. The slide portions 5c and 6c are formed so as to be elastically fitted to the rail 4b from below . The structure.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of an interlocking sliding door according to the present invention will be described below with reference to the drawings.
Three rails 4a, 4b, 4c are arranged in parallel to each other on the lower surface of the top plate of furniture, furniture, etc., and a pair of sliding bodies 1a, 1b, 2a, 2b, 3a, 3b are respectively connected to these rails. The outer door 1, the intermediate door 2, and the inner door 3 are slidably attached. The sliding bodies 1 a, 1 b, 2 a, 2 b, 3 a, 3 b are formed by pivot shafts and are arranged in the vicinity of both front and rear ends of the upper end surfaces of the doors 1, 2, 3. Further, traveling wheels 8 that travel along the lower rail 7 are provided at the lower ends of the doors 1, 2, 3. The above configuration is a general sliding door structure.
[0008]
Thus, in the present invention, a pair of left and right sliders 5 and 6 are slidably mounted on the rail 4b between the sliding bodies 2a and 2b before and after the intermediate door 2 and between the door upper end surface and the rail 4b. Yes. The sliders 5 and 6 are provided with contact pieces 5a, 5b, 6a and 6b extending in the transition path of the outer door 1 and the inner door 3, and all the doors 1, 2 and 3 are shown in FIG. As shown in the figure, when the left slider 5 is fully opened to the left, the body portion of the left slider 5 abuts against the left sliding body 2a of the intermediate door 2 and one abutting piece 5a contacts the left side of the sliding body 1a of the outer door 1. The other abutment piece 5b is arranged so as to be positioned on the right side of the sliding body 3a of the inner door 3, and the main body portion of the right slider 6 abuts on the sliding body 2b of the intermediate door 2 and one abutment piece. 6 b is arranged so as to abut on the right side of the sliding body 3 b of the inner door 3 and the other abutting piece 6 a is located on the left side of the sliding body 1 b of the outer door 1.
[0009]
In the present embodiment, as shown in FIG. 5, the sliders 5 and 6 are provided with slide portions 5c and 6c that fit and slide on the rail 4b. The slide portions 5c and 6c have a directional bulge portion having directivity at the tip and are formed so as to be elastically deformable inward. The slide portions 5c and 6c are formed as shown in FIGS. It is formed so that it can be elastically fitted to the rail 4b by being pushed into the rail 4b from below. Therefore, the sliders 5 and 6 can be attached by one-touch only by pushing into the rail 4b. In addition, because of its structure, it can be integrally molded with synthetic resin and can be manufactured at low cost.
[0010]
Next, the operation will be described. When the outer door 1 is moved rightward, that is, in the closing direction from the fully open posture of FIG. 1, the sliding band 1a of the outer door 1 contacts the contact piece 6a of the right slider 6 as shown in FIG. When the outer door is further moved, the intermediate door 2 is moved together with the right slider 6, and all the doors can be closed as shown in FIG. When the outer door is opened leftward from the closed position in FIG. 3, the sliding band 1a of the outer door 1 contacts the contact piece 5a of the left slider 5, and the intermediate door 2 moves to the left together with the slider 5. The fully open posture of FIG. 1 can be achieved.
[0011]
In the said Example, although the sliding body 1a, 1b, 2a, 2b, 3a, 3b was formed with the pivot axis | shaft, as shown in FIG. 8, it is also possible to form with a general sliding roller. In this case, the contact pieces of the sliders 5 and 6 operate by contacting the shaft portion of the sliding roller.
[0012]
As mentioned above, although the Example considered to be typical of this invention was described, this invention is not necessarily limited only to these Example structures. For example, the sliders 5 and 6 may be of any structure as long as they slide along the rail 4b. In addition, the present invention can be implemented with appropriate modifications as long as it has the above-described configuration requirements, achieves the above-described object, and has the following effects.
[0013]
【The invention's effect】
Since the interlocking sliding door of the present invention is configured as described above, the sliding door structure is different from the conventional sliding door composed of three door bodies that run through the sliding body along three dedicated upper rails laid in parallel. Without any additional work, the slider can be easily reassembled into an interlocking sliding door by simply fitting a pair of sliders into the upper rail for the intermediate door. Thus, there is a remarkable effect that the interlocking sliding door can be provided at an extremely low cost.
