Description

DETAILED DESCRIPTION OF THE INVENTION The present invention connects a plurality of central vertical bars and front and rear vertical bars respectively arranged on the front bales with a plurality of links that rotate in a horizontal plane. The present invention relates to a telescoping door device including a telescoping gate body.

In this type of device, Japanese Patent Application Laid-Open No. 54-84331 has proposed a device that is lightweight and has a simplified connection between the vertical bar and the link.
2. Description of the Related Art Telescopic gates disclosed in Japanese Patent Laid-Open No. 118635/1988 are known. These conventional gates are made of vertical T-pipe to reduce weight, and the link and vertical bar are fixed by expanding the vertical bar from the inside, and crimping this expanded part with a cylindrical part pre-formed on the link. This simplifies the connection structure.

By the way, these conventional telescopic gates have 1IiI vertically
The upper and lower links, which touch and intersect, have a structure in which they stand against each other. For this reason, when assembling, it was necessary to ensure the intersecting relationship with the links that were in contact with each other in the expansion and contraction direction, so he had to repeatedly fit all the links to the vertical bars one by one many times. Position each link with respect to each vertical bar while maintaining the relationship between the upper and lower links,
Next, an operation i must be performed to expand the tube at a predetermined portion of the vertical rod. Therefore, there were problems in that assembly was extremely troublesome and mass productivity was low. Furthermore, in conventional telescopic gates, a retaining collar or an alternative spacing retaining collar is used for each intersecting portion of the links, but these are separate parts from the 41J link. Therefore, there are problems in that the number of parts is large, making assembly even more complicated, and the structure is also complicated.

The present invention was proposed under the above circumstances, and its purpose is to provide a telescoping type door device i1 that is excellent in mass productivity and has a simple structure.

The following will explain the present invention with reference to the drawings.

Figures 1 and 2 show a single-opening telescopic door device, where 1 is the hanging side gatepost, 2 is the doorstop side gatepost, and these are placed upright on the ground A at a distance from each other. There is. A gate main body 4 is cantilever-supported on the hanging side gate post 1 via supports 3, 3. In addition, in the case of this embodiment, the support tool 3. !

In addition, in this embodiment, the cylindrical pivots 19.26 provided on the upper links 15.16 of each unit 8-11 are connected to the front and rear vertical bars 13.14, respectively, and the lower side of each unit 8-11 is Each link 15
．． The case is shown in which the cylindrical pivot 1'1.18k provided at 11s is connected to the central vertical bar 12, respectively. In this embodiment, each connection structure is as shown in FIG.
By expanding the fitting portions of the pivots 17 to 20 of 2 to 14 from the inside, the tube expansion portion 27 is fitted to the pivots 17 to 20.
It is formed by crimping it. By this, each unit 8-11 is connected so that it may not move in the axial direction with respect to each vertical bar 12-14. In addition, for forming the tube expansion part 27,

mm, :19bf was formed in advance at a predetermined location, and first, a first retaining ring of 30 m 1'' was fitted to the first pin 2#a, and the depth of reclamation of the above-mentioned pivots 18 to 20 was determined by this retaining ring of 30 m. After that, the second bead 29b engages with the collar 25 @2
The retaining ring 30bf is fitted to prevent the unit from coming off. Of course, the above-mentioned connection structure tube structure may be configured by an outward bead, an inward bead, and a retaining ring attached to the outward bead and inward bead. Moreover, in the present invention, each vertical bar 1

13..., 14... and each horizontal telescopic link unit 1
- 11 means that, contrary to this embodiment, the upper links 15 and 16't of each unit 8 to 11 are fitted and fixed to the center vertical bar 12 (b) immovably, and the front and rear Vertical bar x
1.14 (b), and each lower link 15.1 ft + t and the central vertical bar 12 are movably fitted, and the front and rear vertical bars J J, 14. They may be connected so as to be fixedly fitted to each other. However, in this case, the relationship between each cylindrical pivot and the corresponding through hole is, for example, reversed from the inside to the outside compared to the present embodiment. Furthermore, in the present invention, as can be seen from FIGS. 8 and 9, each vertical bar 12..., 13...

14... and each of the horizontal telescopic link units 8 to 11 does not necessarily require the rotation of the shaft to be in a fixed state. Therefore, when adopting the connection structure shown in each of these figures, The links 15.1'-- may be rotatably connected to any of the vertical bars 12-14.

In the above configuration, each link IS, 1g, and each vertical bar 12 to 14 are made of metal such as aluminum alloy, iron, or stainless steel, and this example shows the case of stainless steel. .

Although the above-described embodiment has been constructed as described above, the present invention is not limited thereto and can be implemented, for example, in a double-opening telescoping gate device. Furthermore, in the above embodiment, the horizontal expansion/contraction link unit) t-
Two sets of units are installed close to each other at the top and bottom, but the number of units used is determined appropriately based on the height and length of the gate body and design requirements, and at least one unit is installed at the top and bottom. Just set it up. Further, in the above embodiment, the length of the end link 16 is made shorter than the link 15, but the link 1
It may be as long as 5 or longer. In addition, in implementing the present invention, unless it goes against the gist of the invention, horizontal telescopic links, links, end links, cylindrical pivots,
The specific structure, shape, position, material, etc. of the central vertical bar, front vertical bar, rear vertical bar, and connecting means are not limited to the above embodiment, and may be configured and implemented in various ways. Of course you can get it.

The present invention described above has the configuration and gist described in the claims. Therefore, according to the present invention, the gate main body is configured to include a plurality of horizontal telescoping link units (1) which are telescopically formed in advance by pivotally connecting the intersecting portions of the links via a cylindrical pivot. This can be done by connecting the assembly pipe of the gate main body, the central vertical bar, and the front and rear vertical bars to the cylindrical pivot of the unit, respectively. In other words, it requires the troublesome effort of assembling each link one by one for each vertical bar, without considering the cross-relationship with adjacent links in the expansion/contraction direction as in the past. Since the assembly can be performed without any trouble, the work is easy and mass production is excellent. Furthermore, since the cylindrical pivot shaft, which is attached to the link of the horizontal telescopic link unit, also serves as the connecting part to the vertical bar, it does not move in the axial direction of the vertical bar, so the removal of the retaining collar cape is not possible as in the conventional case. No stopping member is required. Therefore, the structure is also simple.
