DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telescopic gate which expands and contracts in a finding direction by a telescopic link formed by connecting a number of cross-shaped links.

[0002]

2. Description of the Related Art Conventionally, as this kind of telescopic gate, for example, the one described in Japanese Utility Model Publication No. 57-27918 is known. The lattices in the telescopic gate are arranged in parallel with each other in the expected direction, and are attached to a pair of vertical lattices that support telescopic links on the inside and to the upper ends of both vertical lattices. And a lattice cap. Openings are formed along the longitudinal direction on the surfaces where the vertical lattices oppose each other, and the ends of the rotating shafts that rotatably connect the telescopic links are formed vertically through the openings. Inserted into the grid. As a result, the rotating shaft slides up and down with respect to both vertical lattices, and the expansion and contraction of the telescopic link, that is, the opening and closing of the telescopic gate, is performed. In such a telescopic gate, the lattice cap fitted to the upper ends of both vertical lattices keeps the distance between the vertical lattices constant and prevents the deformation of each vertical lattice having a “C” cross section. . In addition, as a lattice body of the telescopic gate, there is also known a lattice body in which a connecting member is provided at a lower portion between the vertical lattices, and the connecting member is screwed or riveted to connect the vertical lattices to each other.

[0003]

In such a conventional telescopic gate, since the cap is provided only at the upper end of the vertical lattice, the rigidity of the vertical lattice may be insufficient. For example, if the vertical lattice receives an external force when kicked off with a foot or hits with a ball or the like, the portion receiving the external force may be deformed. If the cross-sectional shape of the vertical lattice is deformed, the rotation axis of the telescopic link may not be able to slide smoothly in the vertical lattice, and furthermore, the telescopic gate may not be able to be opened and closed.

[0004] The vertical lattice is formed by simply cutting an extruded profile, and the outer and inner surfaces of the vertical lattice are subjected to a surface treatment by painting or the like. Corrosion may occur starting from this part. In addition, if the fore-edge of the vertical lattice is exposed, the telescopic gate will be of poor overall design. Further, in the case of a telescopic gate in which the vertical lattices are connected by using screws or rivets, the construction is complicated, and in addition, if the screws or the like are seen on the front side, the design becomes poor.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and can increase the rigidity of a vertical lattice in a lattice of a telescopic gate, thereby effectively preventing deformation due to external force or the like. An object of the present invention is to provide a telescopic gate having excellent workability and design.

As shown in FIG. 1, the telescopic gate 1 is of a so-called vertical pant type used for a gate of a parking lot or the like, and is telescopically attached between left and right support members 2. One end of the telescopic gate 1 is attached to one pillar member (right pillar member in FIG. 1) 2 via hinges 3 and 3,
The other end is hung by a latch (not shown) or the like against the other strut member (the left strut member in FIG. 1) 2 in a state where it abuts. The illustrated state is a state in which the telescopic gate 1 is closed. From this state, the telescopic gate 1 is contracted rightward, and furthermore, the telescopic gate 1 is opened by rotating the hinge 3 around the center.

The telescopic gate 1 comprises a pair of end members 4 and 4 disposed at both ends, a plurality of lattice members 15 equally disposed between the end members 4 and 4, and both end members 4 and 4. In addition, the telescopic link 6 is supported by the lattice members 15, and the end members 4 on the distal end side in the extension direction, and the casters 7 provided at a ratio of one to the five lattice members 15.

The lattice body 15 is attached so as to connect a pair of vertical lattices 20 formed of a shape member having a C-shaped cross section, and to connect the upper ends and the lower ends of the two vertical lattices 20, 20, respectively. Upper lattice cap 21 and lower lattice cap 10
It is composed of

The telescopic link 6 is a parallel link mechanism in which cross-shaped links of diagonal lattices arranged in two rows in the expected direction are doubled in a row. Are provided (see FIG. 7). A pair of end members 4 and a plurality of lattice members 15 are arranged at positions where the three rotating shafts 24, 25, 26 are aligned in the vertical direction. In this case, the lowermost shaft 26 of the three rotation shafts is fixed to each end member 4 and the vertical grid 20 of each grid body 15, and the other two shafts 24 and 25 are Is slidably mounted in the vertical direction with respect to the member.

Therefore, when the telescopic link 6 is expanded and contracted in the left-right direction, each end member 4 and each grid body 15 move in the left-right direction while maintaining a vertical position while maintaining an equal interval. Itself is a fixed rotating shaft 2
6 expands and contracts in the vertical direction. Further, at this time, the caster 7 supports the telescopic link 6 while rolling so that the telescopic link 6 does not tilt in the left-right direction.

As shown in this figure, each vertical grid 20 of the grid body 15 is formed in a cross section of “C” shape, and is arranged so that openings 23 provided along the longitudinal direction face each other. Both edges of the opening at the lower end of the opening 23 are further cut out in a U-shape.
The cap 23 is formed by gradually widening the opening 23 toward the lower end of the cap.

As shown in FIGS. 2 to 6, the lower lattice cap 10 has left and right cap portions 11, 11 mounted on both small openings 20a, 20a of both vertical lattices 20, 20, respectively.

Also, as shown in FIG. 6, the cross-sectional shape of the connecting portion 11b is formed in the same inverted U shape as that of the cap portion 11, as shown in FIG. The covering portion 12 is formed by a lower peripheral portion of the fitting portion 11a and the connecting portion 1.
Along the lower edge of 1b, the vertical grid 20 is formed in a rib shape by the thickness of the vertical grid 20. When the lower lattice cap 10 is attached to the vertical lattice 20, the covering part 12 in each cap part 11 has its upper surface 12a abutting on the fore edge 20a to cover the fore part 20a.

As shown in FIG. 3, a pair of vertically long notches 13 are formed between the cap portions 11, 11 and the connecting portion 11b at right angles to the longitudinal direction of the connecting portion 11b. As shown in FIG. 4, a vertically long through hole 13a is formed from the center of the notch 13 to the lower side. Further, the upper part of the notch 13 and the peripheral edge of the upper end of the fitting parts 11a, 11a are chamfered so that the fitting part 11a can be easily fitted to the fore edge 20a. Further, the connecting portion 11b
