DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on embodiments shown in the accompanying drawings. In the embodiment shown in the attached drawings, the gate panel body 1 is composed of upper and lower horizontal frames 30 made of metal and both side frames 4 made of metal.
And a grid member, a face plate 13 and the like are attached to a portion surrounded by a rectangular frame. As shown in FIG. 1, a substantially semicircular concave groove 5 is formed on the side surface of the side frame 4 made of metal.
A shaft portion 7 having a circular or C-shaped cross section is protruded from one end of the concave groove portion 5 through a neck portion 6 toward the center of the arc of the substantially semicircular concave groove portion 5. It is set up. An arc-shaped protruding piece 29 for preventing finger jamming extends from a base protruding the neck 6 at one end of the wall of the concave groove 5 along an extension of the arc of the substantially semicircular concave groove 5.

The hinge body 2 is made of metal and is long in the vertical direction. The hinge 9 projects a projecting piece 9 from the center of the back surface of the vertical frame member 8 and has a C-shaped bearing on both sides of the tip of the projecting piece 9. 10 are provided. The side end portions of the gate panel body 1 are foldably connected to each other via a metal hinge body 2. In this case, the shaft 7 is turned inside the two bearing portions 10 of the hinge body 2. It is movably fitted and connected. Here, the opening 10a of the bearing unit 10 in a state where the adjacent gate panel body bodies 1 are extended.
Is set so that the outer surface of the shaft portion 7 located at the position. Further, the inner surface of the groove 5 and the bearing 1 are so fixed that the outer surface of the bearing 10 does not contact the inner surface of the groove 5.
A gap 11 is formed between the outer surface and the outer surface.

The telescopic gate 3 of the present invention has a basic configuration in which a plurality of gate panel bodies 1 are folded via the hinge body 2 so as to be freely expandable as described above. In the illustrated embodiment, as shown in FIGS. 5 to 7, in addition to the above-described configuration, an upper connecting bar 14 and a lower connecting bar 15 are further provided.
Are rotatably supported on the upper and lower ends of another hinge body 2 ', respectively, and the upper connecting bar 14 is arranged so as to cross over the gate panel body 1 and the lower connecting bar 15 Are arranged so as to cross below the gate panel body 1, and the center of the upper connecting bar 14 and the center of the horizontal frame 30 above the gate panel body 1 are pivotally pivoted by the shaft 16. The central portion of the lower connecting bar 15 and the central portion of the horizontal frame 30 below the gate panel body 1 are pivotally supported by a shaft 16 so as to be rotatable. Then, the side end of the gate panel element body 1 located at the end and the side end of the upper connection bar 14 and the lower connection bar 15 located at the end are respectively attached to the shaft support 18 of the end vertical frame 17. It is pivotally supported.

Therefore, a plurality of gate panel element bodies 1 that can be folded and extended via the hinge body 2 and a plurality of upper and lower connecting bars 14 and 15 that can be folded and extended via the hinge body 2 '. Makes up the registration. One of the end vertical frames 17 located at both ends of one of the telescopic gates 3 is rotatably attached to a gate post 19 by a hinge 20.
A caster 21 is attached to a lower end portion of an arbitrary hinge body 2 among the vertically long hinge bodies 2. When the telescopic gate 3 is to be deployed, the other end vertical frame 17 is grasped by hand and the telescopic gate 3 is pulled, so that the gate panel panel bodies 1 adjacent to each other via the hinge body 2 are connected to each other. The upper and lower connecting bars 14 and 15 adjacent to each other via the 2 'portion extend, whereby the telescopic gate door 3 having the above-mentioned resisting structure extends and closes the entrance. On the other hand, by grasping the other end vertical frame 17 by hand and pushing the telescopic gate 3 from the spread state, the gate panel panel bodies 1 adjacent to each other via the hinge body 2 and the hinge body 2 ′ via the hinge body 2 ′. The upper and lower connecting bars 14 and 15 that are adjacent to each other are folded, respectively, so that the telescopic gate 3 having the above-described resisting configuration is formed.
Will shrink and open the doorway.

The telescopic gate 3 is opened and closed by expanding and contracting as described above. In this case, at the time of folding, the shaft 7 of the gate panel body 1 is connected to the bearing 10 of the hinge 2.
1 → FIG. 2 → FIG. 3 → FIG. 4, and conversely, at the time of extension, the shaft portion 7 of the gate panel body 1 is hinged.
4 → FIG. 3 → FIG. 2 → FIG.

When the telescopic gate 3 that opens and closes is used to open and close an entrance of a garage or the like, the door is generally extended and closed at the time of extension and at the time of folding as shown in FIG. The state is longer, and the door 3 is folded and the entrance is opened only when the vehicle opens and closes when the door 3 is opened. Therefore, the appearance of the door 3 is particularly problematic in terms of time. However, the appearance in the extended state becomes a problem. Then, in the present invention, at the time of spreading as shown in FIG. 1 in which the appearance is problematic, the shaft 7 positioned at the opening 10a of the bearing 10 in a state where the adjacent gate panel element bodies 1 are spread. Since the outer surface is set so as to face the inner surface of the groove 5, the outer surface of the shaft 7 is not visible from the outside, and only the outer surface of the bearing 10 is visible to the outside. Therefore, the phenomenon in which the outer surface of the shaft portion 7 that has been scratched by sliding contact with the inner surface of the bearing portion 10 appears to shine outside is eliminated. At this time, although the groove 5 is provided so that the outer surface of the shaft 7 located at the opening 10 a of the bearing 10 is not visible from the outside, there is a gap between the inner surface of the groove 5 and the outer surface of the bearing 10. Since the bearing 11 is formed, the outer surface of the bearing 10 seen from the outside does not slidably contact with the inner surface of the groove 5 and is not damaged.
By seeing only the outer surface of the camera, a beautiful state can be visually recognized forever.

By the way, as in the present invention, the shaft 7 is connected to the shaft 7 through the neck 6 from one end of the substantially semicircular groove 5 formed on the side surface of the side frame 4. The protruding piece 9 protrudes toward the center side of the arc, and protrudes from the center of the back surface of the vertical frame member 8.
Is provided to form the hinge body 2, and the shaft portion 7 is rotatably fitted into both bearing portions 10 of the hinge body 2.
As shown in FIG. 4, the width of the gap between the outer surface of the shaft portion 7 located at the opening 10a of the bearing portion 10 and the back surface of the vertical frame member 8 is increased, and there is a possibility that a finger may be packed in this portion. Groove 5
An arc-shaped protruding piece 29 for preventing finger jamming is continuously extended from a base protruding the neck portion 6 at one end of the wall portion along an extension of the arc of the substantially semicircular concave groove portion 5. In the folded state, the gap between the outer surface of the shaft portion 7 located exactly at the opening 10a of the bearing portion 10 and the back surface of the vertical frame member 8 is hidden by the arc-shaped protruding piece 29. Is prevented from being packed. Also, as already mentioned,
The state in which the telescopic gate 3 used for the entrance of the garage or the like is folded is shorter in time than the spread state, so that the appearance is not so much a problem as in the spread state. The piece 29 covers and hides the outer surface of the shaft portion 7 located at the opening 10a of the bearing portion 10 at the time of folding, so that also in this case, the outer surface of the shaft portion 7 damaged by sliding contact is not visible from the outside, and the appearance is reduced. It will be better.

The structure of the pivotal connection between the upper and lower connecting bars 14, 15 and the hinge 2 'is not particularly limited, but may be the same as that of the gate panel 1 and the hinge 2 described above. Is also good.

[0015]

According to the present invention, as described above, a substantially semicircular concave groove is formed in the side surface of the metal side frame at the side end of the gate panel body. A shaft section having a circular or C-shaped cross section is protruded from one end of the vertical frame member through the neck toward the center of the arc of the substantially semicircular concave groove section, and a projecting piece is formed from the center of the back of the vertical frame member. A C-shaped bearing portion is provided on both sides of the tip of the protruding piece to protrude and constitute a hinge body, and the shaft portion is rotatably fitted into both bearing portions of the hinge body, so that adjacent gate panel panels are provided. In the extended state, the outer surface of the shaft located at the opening of the bearing is set so as to face the inner surface of the groove, so that in the extended state, the outer surface of the shaft is out of the bearing on the outer surface of the shaft. The exposed part is hidden by the wall of the groove and is not exposed to the outside,
As a result, in the extended state, the outer surface of the shaft portion that is damaged by sliding contact with the inner surface of the bearing portion cannot be seen from the outside, so that the appearance is improved, and the outer surface of the bearing portion has the concave groove portion. Since a gap is provided so as not to contact the inner surface, the outer surface of the bearing portion exposed to the outside at the time of extension does not slide on the inner surface of the concave groove portion, and there is no possibility that the outer surface of the bearing portion is damaged, In this respect, the appearance is not impaired.
