【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. In the embodiment shown in the accompanying drawings, the gate panel body 1 includes a grid material or a grid material in a portion surrounded by a rectangular frame body composed of upper and lower metal horizontal frames 30 and metal side frames 4 on both sides. The face plate 13 and the like are attached and configured. As shown in FIG. 1, a substantially semicircular concave groove portion 5 is formed on a side surface portion of a metal side frame 4, and a circular cross section is formed from one end portion of the concave groove portion 5 through a neck portion 6. A shaft portion 7 having a C-shaped cross section is provided so as to project toward the center side of the arc of the substantially semicircular concave groove portion 5. From the base portion projecting the neck portion 6 at one end of the wall portion of the recessed groove portion 5, an arc-shaped finger-tightening prevention projection 29 is extended along the extension line of the arc of the recessed groove portion 5 having a substantially semicircular shape. .

The hinge body 2 is made of metal and is long in the up-down direction. The hinge body 2 projects a protruding piece 9 from the center of the back surface of the vertical frame member 8 and has C-shaped bearings on both sides of the tip of the protruding piece 9. It is configured by providing a section 10. The side ends of the gate panel body 1 are foldably connected to each other via a metal hinge body 2. In this case, the shaft portion 7 is provided in both bearing portions 10 of the hinge body 2. It is rotatably fitted and connected. Here, it is set so that the outer surface of the shaft portion 7 located in the opening 10a of the bearing portion 10 faces the inner surface of the recessed groove portion 5 in a state where the adjacent gate panel body 1 is extended. Further, a gap 11 is formed between the inner surface of the groove portion 5 and the outer surface of the bearing portion 10 so that the outer surface of the bearing portion 10 does not contact the inner surface of the groove portion 5.

The expansion / contraction gate 3 of the present invention has a basic form in which a plurality of gate panel bodies 1 are folded and spreadable via the hinge body 2 as described above. In the illustrated embodiment, as shown in FIGS. 5 to 7, in addition to the above-described structure, both ends of the upper connecting bar 14 and the lower connecting bar 15 can be respectively rotated to the upper and lower ends of another hinge body 2 '. And the upper connecting bar 14 is arranged to cross above the gate panel body 1, and the lower connecting bar 15 is arranged below the gate panel body 1 to cross. A central portion of the upper connecting bar 14 and a central portion of the horizontal frame 30 above the gate panel body 1 are rotatably supported by a shaft 16, and a central portion of the lower connecting bar 15 and the gate panel body 1 are supported. A central part of the lower horizontal frame 30 is rotatably supported by a shaft 16. It has been configured. Then, the side end portions of the gate panel body 1 located at the end portions and the side end portions of the upper connecting bar 14 and the lower connecting bar 15 located at the end portions are connected to the shaft supporting portion 18 of the end vertical frame 17. Each is rotatably supported.

Therefore, a plurality of gate panel bodies 1 that can be folded and extended via the hinge body 2 portion, and a plurality of upper and lower connecting bars 14 and 15 that can be folded and extended via the hinge body 2 ′ portion. It constitutes the regent tongue. One of the end vertical frames 17 located at both ends of one expandable gate 3 is rotatably attached to a gate post 19 by a hinge 20. A caster 21 is attached to the lower end of any hinge body 2 of the hinge bodies 2 that are long in the vertical direction. When the expandable gate 3 is deployed, the other end vertical frame 17 is grasped by hand and the expandable gate 3 is pulled, so that the adjacent panel body 1 for gates via the hinge body 2 portion, the hinge. Adjacent upper and lower connecting bars 14 and 15 are respectively extended through the body 2 ', whereby the expansion and contraction gate 3 having the above-described resisting configuration is extended to close the doorway. On the other hand, by grasping the other end vertical frame 17 by hand and pushing the expandable gate 3 from the expanded state, the gate panel panel bodies 1 adjacent to each other via the hinge body 2 portion and the hinge body 2'portion are interposed. As the upper and lower connecting bars 14 and 15 adjacent to each other are respectively folded, the expansion / contraction gate 3 having the above-described resisting configuration is contracted to open the doorway.

As described above, the telescopic gate 3 is expanded and contracted to open and close. In this case, the shaft portion 7 of the gate panel body 1 moves inside the bearing portion 10 of the hinge body 2 when folded. 1 → FIG. 2 → FIG. 3 → FIG. 4, and conversely, at the time of expansion, the shaft portion 7 of the gate panel body 1 moves inside the bearing portion 10 of the hinge body 2 as shown in FIG. 4 → FIG. 3 → FIG. 2 → It will rotate as shown in Fig. 1.

By the way, when the opening / closing expandable gate 3 is used to open / close the entrance / exit of a garage or the like, it is generally expanded and closed as in the case of FIG. 1 at the time of expansion and folding. The state is longer, and the expansion gate 3 is folded to open the door only when the vehicle opens and closes when the expansion gate 3 is opened. Therefore, the appearance of the expansion gate 3 becomes a problem especially at time. However, the appearance in the long stretched state is a problem. In the present invention, the shaft portion 7 located in the opening portion 10a of the bearing portion 10 in a state in which the adjacent panel body 1 for the gate is spread at the time of spreading as shown in FIG. Since the outer surface of the shaft section 7 is set to face the inner surface of the groove 5, the outer surface of the shaft section 7 cannot be seen from the outside, and only the outer surface of the bearing section 10 can be seen to the outside. Therefore, the phenomenon that the outer surface of the shaft portion 7 which is damaged by sliding contact with the inner surface of the bearing portion 10 appears to shine outside is eliminated. At this time, even though the concave groove portion 5 is provided so that the outer surface of the shaft portion 7 located in the opening portion 10a of the bearing portion 10 cannot be seen from the outside, the concave groove portion 5 is provided between the inner surface of the concave groove portion 5 and the outer surface of the bearing portion 10. Since the gap 11 is formed, the outer surface of the bearing portion 10 that is visible from the outside does not come into sliding contact with the inner surface of the recessed groove portion 5 and is not scratched, and only the outer surface of the bearing portion 10 that is not damaged from the outside is formed. By seeing it, you will be able to see the beautiful condition forever.

By the way, as in the present invention, the shaft portion 7 of the substantially semicircular concave groove portion 5 is formed from one end of the substantially semicircular concave groove portion 5 formed on the side surface portion of the side frame 4 through the neck portion 6. The hinge body 2 is formed by projecting toward the center of the arc, projecting the projecting piece 9 from the center of the rear surface of the vertical frame member 8 and providing the bearing portions 10 on both sides of the tip of the projecting piece 9 to form the hinge body 2. When the shaft portion 7 is rotatably fitted into both the bearing portions 10 of the body 2, as shown in FIG. 4, the outer surface of the shaft portion 7 located at the opening 10a of the bearing portion 10 and the vertical frame member 8 are formed. Although the width of the gap between the rear surface and the back surface may be widened, there is a risk that fingers may be stuffed into this portion. However, the semi-circular concave groove portion 5 is formed from the base portion projecting the neck portion 6 at one end of the wall portion of the concave groove portion 5. Since the finger-tightening prevention projections 29 are continuously extended along the extension line of the circular arc, just keep the shaft in the folded state as shown in FIG. The gap between the outer surface of the shaft portion 7 located in the opening 10a of the receiving portion 10 and the back surface of the vertical frame member 8 is hidden by the projecting piece 29, and it is possible to prevent the finger from being stuffed in this portion. become. In addition, as already mentioned, the state in which the expansion gate 3 used for the entrance and exit of a garage or the like is folded is shorter than that in the extended state, so the appearance is not a problem as much as in the extended state. As shown in FIG. 4, the projecting piece 29 covers and hides the outer surface of the shaft portion 7 located in the opening portion 10a of the bearing portion 10 at the time of folding, and in this case also, the outer surface of the shaft portion 7 damaged by the sliding contact is external. It is invisible from the outside and has a good appearance.

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

[0017]

[Effect of device]

 In the present invention, as described above, a substantially semicircular concave groove is formed on the side surface of the metal side frame at the side end of the gate panel body, and the concave groove is formed from one end of the concave groove to the neck. Via a circular cross section or a C-shaped cross section, projecting toward the center of the arc of the semi-circular concave groove, projecting the projecting piece from the center of the rear surface of the vertical frame member and projecting the projecting piece. C-shaped bearings are provided on both sides of the front end of the to form a hinge body, and the shaft portions are rotatably fitted in the bearings of the hinge body so that adjacent gate panel bodies are adjacent to each other. Since the outer surface of the shaft located in the opening of the bearing in the expanded state is set to face the inner surface of the groove, it is exposed outside from the bearing on the outer surface of the shaft in the expanded state. The part to be covered is hidden by the wall of the groove and is not exposed to the outside. The outer surface of the shaft, which was damaged by the sliding contact with the inner surface of the receiving part, will not be visible from the outside, and the appearance will be improved, and the base part protruding from the neck of one end of the wall of the groove will be exposed. From the front of the vertical frame member, pull out the finger-tightening prevention protrusions along the extension of the arc of the semi-circular groove and fold the adjacent gate panel elements together. Since the gap between the shaft and the outer surface of the shaft is shielded, the outer surface of the shaft that faces the opening of the bearing is hidden by the protrusion when the expansion gate is folded and is exposed to the outside. As a result, the outer surface of the shaft, which was damaged by sliding contact with the inner surface of the bearing, is not visible from the outside even in the folded state, which also improves the appearance. There is no risk of finger-stuffing in the wide gap between the back of the material and the shaft.
