148549, Utility Model Application Publication No. 59-63192, etc.
The former consists of a large number of connecting rods that are pivoted in an intersecting manner when viewed from the front between the lower pillars, and the latter is made up of a large number of connecting fittings that are pivoted in an intersecting manner when viewed from the plane between the lower pillars. Become. However, all of them have a diagonal or vertical lattice shape when viewed from the front, and are not very decorative. Therefore, even though this type of horizontally extending telescopic door is often used for store (tenant) partitions, building entrances, entrances, garage entrances, etc., it lacks interior design and is unsuitable for improving the image. It was hot.

[Purpose of the invention] This invention was devised in view of the above-mentioned points, and it improved the connector that connects the lower pillars to make it more decorative when viewed from the front, and also improved the connector itself. The purpose of the present invention is to provide a horizontally pulling telescopic door that is lightweight and easy to handle, allowing for the selection of various designs through arrangement and combinations.

[Summary of the invention] Therefore, in this invention, the support columns that are suspended as appropriate are inserted and fixed into each of the plurality of connectors, and the connectors are arranged adjacent to each other so that they can be placed above and below each other. A connector pillar is inserted through the overlapping connecting portions, and the connector is pivoted using the connector pillar as a support axis, so that the connector can be expanded and contracted in the horizontal direction, and the connector has the following features:
This connector is formed of a plate-like body that has an appropriate shape when viewed from the front, and has a support insertion hole in the center that extends in the vertical direction through which the support column is inserted, and on both sides,
One of them is a connecting part with an upper part protruding, and the other one is a connecting part with a lower part protruding, and the connecting part is passed through the connecting parts on both sides that match in the vertical direction when the connectors themselves are placed adjacent to each other. A connecting penetration hole for insertion is opened along the vertical direction, a stopper surface is formed on the side surface of the connecting portion, and a stopper receiving surface to which this stopper surface comes into contact is formed on the side surface of the disc-shaped body body, This method consists in that the connecting devices arranged adjacent to each other in the extended state are formed so as to restrict each other to a certain expansion angle.

[Embodiment of the invention] An embodiment of the invention will be described below with reference to the drawings.

Reference numeral 1 shown in the figure is a fixed frame, with fixed part vertical frames 2A and door stop vertical frames 2 erected on both sides.
B. A horizontal frame is attached to the hanger rail 3 which is installed between the upper ends of the fixed part vertical frame 2A and the door stop vertical frame 2B. Further, in some cases, a guide rail 4 for guiding movement and running at the lower end is installed and integrated between the lower ends of the fixed part vertical frame 2A and the door stop vertical frame 2B.

A fixed frame 1 installed as a horizontal frame in this way is provided with an expandable and retractable structure consisting of a large number of supporting columns 5, connecting columns 7, and connectors 8 that connect these supporting columns 5 and connecting columns 7 to each other in the horizontal direction. The door body is installed in a hanging manner so that it can expand and contract in the horizontal direction. That is, the runner 6 attached to the upper end of the support column 5 in a vertically adjustable manner is rotatably engaged with the hanger rail 3 and suspended, so that the runner 6 moves and runs along the hanger rail 3 and expands and contracts. If possible and necessary,
The lower end of the support column 5 is slidably fitted into the guide rail 4.

The connector 8 forms a disk-shaped body 9 that has an appropriate shape when viewed from the front, and the support column 5 is inserted through the center of the disk-shaped body 9, and the connectors 8 themselves arranged adjacent to each other are connected to each other on both sides. In addition, the connector column 7 can be inserted through the connecting portions 11 that overlap above and below.

As shown in FIGS. 1 and 4, the disk-shaped body 9 in the illustrated example has a semicircular portion and a horizontally elongated rectangular portion integrally formed at the top and bottom, through which the supporting columns 5 are inserted. A support insertion hole 10 is opened along the vertical direction, and the support column 5 inserted therethrough is fixed to the plate-shaped body 9 (see FIG. 5). Also, on both sides, one has a connecting part 11 with an upper part protruding and the other with a lower part protruding, and when the connecting parts 8 themselves are arranged adjacent to each other, the connecting parts 11 on both sides match in the vertical direction. Connecting penetration hole 1 through which the connector column 7 is inserted through the portion 11
2 is opened along the vertical direction, and the connector column 7 inserted therein makes the connectors 8 swingable relative to each other and connects the connector 11 on either the upper or lower side.
(See Figure 5). In this way, by protruding the upper part on one side and the lower part on the other on both sides, the connecting devices 8 themselves that are connected adjacently have the same structure, reducing the molding cost,
Improve efficiency of assembly work. Of course, it is possible to prepare and assemble two types, one with the upper part protruding on both sides and the other with the lower part protruding.

Note that the connecting portion 11 is connected to the disk-shaped body 9 as shown in the figure.
One of them is arranged to protrude forward and the other to the rear, for example, the connecting part 11 on the lower side is located in the front, and the connecting part 11 on the upper side is located in the rear. Furthermore, in consideration of smooth alignment of the protruding connecting portion 11 with the main body of the disk-like body 9, a positioning protrusion 13 is provided at the end of the disk-like body 9.

The connecting parts 11 that match in the vertical direction are extended in the horizontal direction by swinging around the connecting pillars 7 inserted through each other as a support shaft, and in the extended state, as shown in FIG. It looks like a zigzag. That is, a stopper surface 14 is formed on the side surface of the connecting portion 11, and a stopper receiving surface 15 that this stopper surface 14 comes into contact with is formed on the side surface of the main body of the disc-shaped body 9, so that the mutually adjacent connectors 8 themselves support the connector column 7. When it is swung and extended as a support shaft, the stopper surface 14 and the stopper receiving surface 15 come into contact with each other and are regulated to a constant expansion angle. For example, the expansion angle is
The expansion angle is set at 150° at the positions of the connecting columns 7 which are alternately located in front and behind with respect to the arrangement direction of the supporting columns 5 suspended from the hanger rail 3. Of course, this expansion angle is not limited to this, and for example, it depends on the length of the sideward protrusion of the plate-like body 9 that the connecting portion 11 faces, the stopper surface 14,
Various changes can be made by changing the angle of the stopper receiving surface 15, etc.

Furthermore, in the illustrated example, a fan-shaped, rectangular, or other through hole 16 is bored to enable viewing inside and outside the compartment during installation, and the through hole 16 allows the connector 8 itself to be seen through the hole 16. Bringing change to the design. Furthermore, it goes without saying that the outer shape of the connector 8 is not limited to the illustrated example.

The connector 8 itself is made of synthetic resin such as polyacetal resin, which has excellent bending strength, compressive strength, and impact strength, so it has excellent impact resistance, but it is not limited to this and can be made of various materials. Can be molded into various colors. In addition, when the device is opened and closed by expanding and contracting the entire device, little opening and closing noise is generated, and the device is lightweight and easy to handle. The supporting columns 5 and the connecting columns 7 are made of round pipes made of stainless steel or aluminum to reduce their weight.

Thus, the connector 8 can be freely selected vertically and combined with the support column 5 and the connector column 7, and as shown in FIG. Arranged in a single character. Further, although not shown in the drawings, a two-stage arrangement, a staggered arrangement in which the upper and lower parts are alternately arranged, a spot arrangement in which the arrangement is scattered throughout, etc. can be arbitrarily performed.

Further, when configured as a whole, as shown in FIG. 2, the support column 5 located at one end in the expansion/contraction direction is fixed to the fixed part vertical frame 2A, and the support column 5 located at the other end is fixed to the fixed part vertical frame 2A. It can be locked to the door stop vertical frame 2B via a main pillar 17 pivotally supported thereon.

This invention is constructed as described above, and is opened and closed by extending and contracting in the horizontal direction while suspended from the hanger rail 3 of the fixed frame 1. As shown in Fig. 2, in the extended and closed state, the hanger rails 3 are arranged adjacent to each other. The connected connectors 8 are expanded around the connector column 7 as a support shaft, and the stopper surface 14 and the stopper receiving surface 15
When they come into contact with each other, they are regulated to a certain angle and form a zigzag shape. Further, as shown in FIG. 3, in the contracted open state, the connectors 8 are folded and stored so as to be closed using the connector pillar 7 as a support shaft, and the storage space at that time is reduced to about one-sixth.

[Effects of the invention] Therefore, in this invention, the support columns 5 suspended as appropriate are inserted through and fixed to each of the plurality of connectors 8, and the connectors 8 are arranged adjacent to each other to connect them. The connector pillar 7 is inserted through the upper and lower overlapping connecting parts 11, and the connector 8 is swung using the connector pillar 7 as a support axis, so that it can be expanded and contracted in the horizontal direction. It is formed of a plate-shaped body 9 that has an appropriate shape when viewed from above, and since the connecting devices 8 arranged adjacent to each other in the extended state are regulated to a certain expansion angle, it is decorative when viewed from the front. In addition, various designs can be selected by arranging and combining the connectors 8 themselves, and the connectors are lightweight and easy to handle.

In addition, a support penetration hole 10 is formed in the center of the connector 8 in the vertical direction through which the support column 5 is inserted, and one of the two sides has an upper part, and the other has a lower part. The connecting holes 12 for inserting the connector pillars 7 into the connecting parts 11 on both sides that match in the vertical direction when the connecting parts 8 themselves are arranged adjacent to each other are formed in the vertical direction. In addition, a stopper surface 14 is formed on the side surface of the connecting portion 11, and a stopper receiving surface 15, which the stopper surface 14 comes into contact with, is formed on the side surface of the main body of the disc-shaped body 9, so that the connecting portion 11 can be connected adjacently. The connector 8 itself has the same structure, which reduces molding costs and improves the efficiency of assembly work.In addition, it provides a sense of unity with excellent decorativeness, and is also strong. It is excellent.

Therefore, it can be used for many purposes such as partitions in stores (tenants), building entrances, entrances, garage entrances, etc.
Moreover, in the extended state, it is not only linear, but
It is also possible to lay it in a curved manner, and it has various excellent effects such as excellent strength and excellent decorativeness.
