2. Description of the Related Art In a telescopic gate of this type, it is necessary to fix a predetermined pin axis of a telescopic link having a plurality of inclined links mutually assembled in an X-shape to a plurality of vertical rails so as not to be vertically slidable. However, in a conventional general telescopic gate, each vertical rail and the telescopic link are usually fixed to the pin axis of the telescopic link from the outside of the vertical rail with rivets or the like. By the way, when the vertical rail and the pin shaft of the telescopic link are fixed from the outside of the vertical rail with rivets or the like, there is a disadvantage that the fixed part (rivet) is exposed to the outside and the appearance is deteriorated.

On the other hand, as a telescopic gate which has improved the above-mentioned appearance problem, there is a conventional telescopic gate shown in FIGS. 6 and 7 (Japanese Utility Model Laid-Open No. 1-109090). In this known telescopic gate, as shown in FIG. 7, the main vertical rail 101 and the pin shaft 123 of the telescopic link 102 are fixed with screws 105 from the outer surface side of the main vertical rail 101, and then the main vertical rail 101 is fixed. The outer surface is covered with a cover material 103. This cover material 103
Are attached to the main vertical rail 101 by concave-convex fitting. In addition, on the pin shaft 123, inclined links 121 and 122, spacers 109, and the like that are inclined to the left and right sides are fitted.

[0004]

However, in the known telescopic gate shown in FIGS. 6 and 7, since the outer surface of the main vertical bar 101 is covered with the cover material 103, it is exposed to the outer surface of the main vertical bar 101. Although the screw 105 is not visible from the outside, since the cover member 103 is merely fitted to the main vertical rail 101, there is a problem that the cover member is easily detached by an external force such as an external impact, and the main vertical member 101 has a problem. The joints P, P between the crosspiece 101 and the cover member 103 are visible from the outside and the appearance is poor. Further, when the main vertical rail 101 is detached from the pin shaft 123 for repairing the main vertical rail 101, the pin shaft 123
Spacer 109 and each inclined link 12
1, 122 etc. may come off from the pin shaft 123,
There is also a problem that the reassembly work performed later becomes troublesome.

The present invention has been made in view of the above-mentioned problems of the known telescopic gates, and can improve the appearance of the exterior, prevent the external beams from being adversely affected even when an external force is applied to the vertical beams, and provide the vertical beams. It is an object of the present invention to provide a telescopic gate capable of easily performing the repair work.

[0006]

According to the present invention, a plurality of upper right slope links and a plurality of right lower slope links are mutually connected by X.
Crosses each other, and the respective crossing positions are pivotally connected to each other with a pin axis to form a telescopic link that is expandable and contractible in the left-right direction. In a telescopic gate having a shaft fixed to allow each of the vertical bars to be able to expand and contract in the left-right direction, the vertical bar has left and right side plates and an outer plate, and is vertically elongated on a side facing the outer plate. It is formed in the shape of a hollow rod provided with an opening, and a guide groove capable of guiding the connecting material in the vertical direction and a partition wall located on the outer face plate side with respect to the guide groove are provided inside the vertical rail, and are fixed to the vertical rail. The connecting member is fixed to the partition wall by screwing a screw into the partition wall from the opening of the vertical rail while the pin shaft is fixed to the connecting member inserted into a predetermined position of the guide groove.

[0007]

According to the telescopic gate of the present invention, the pin is fixed to the connecting member inserted into the guide groove of the vertical rail at a predetermined position, and the connecting member is fixed to the vertical rail. Screws are screwed into and fixed from the openings provided on the side of the vertical bar facing the outer surface plate of the vertical bar, so that even if the vertical bar is a single molded product, The fixing means (connecting material, rivet, screw, etc.) for fixing the vertical rail and the pin shaft is not exposed on the outer surfaces of the side plate and the outer plate. Further, the pin shaft fixed to the vertical rail is fixed to the connecting member, and since the pin shaft is fixed to the vertical rail via the connecting member, the vertical bar is separated from the pin shaft for repair, for example. Even when this is done, the inclined link or the like fitted on the pin shaft does not come off from the pin shaft.

[0008]

[Effect of the Invention] The telescopic gate of the present invention has the following effects.

(1) Since the fixing means (connecting material, rivet, screw, etc.) between the vertical rail and the pin shaft is inside the vertical rail and is not exposed to the outside of the vertical rail, the appearance is improved.

(2) Since the vertical bar can be formed as a single molded product and the connecting member for connecting the pin shaft is screwed in the vertical bar, even if external force is applied to the vertical bar, the vertical bar can be connected to the vertical bar. There is no significant adverse effect on this, and the durability of the vertical rail is improved.

(3) Since the pin shaft of the telescopic link is connected to the vertical bar while being fixed to the connecting member, even if the vertical bar is separated from the pin shaft for repairing the vertical bar, for example, The inclined link or the like fitted on the shaft does not come off from the pin shaft, and the work at the time of reassembly becomes easy.
