Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a connecting device for connecting a pivot shaft to a crosspiece of a telescoping gate.

[Prior art]

Telescoping gates are made by intersecting multiple crosspieces in a continuous manner, and passing pivot shafts such as vertical crosspieces through the pivot points at the ends and intersections, and the crosspieces rotate around the pivot shafts to complete the whole structure. It can be expanded and contracted in the horizontal direction.

Conventionally, when inserting a pivot shaft into the end of a crosspiece, a small end cap is attached to the edge of the crosspiece, and a smooth hole is inserted into the pivot shaft insertion hole drilled on two parallel sides of the crosspiece. Each was fitted with a collar to enable rotation.

[Problems to be solved by this idea]

Therefore, there are problems in that it takes time and effort to attach the edge cap and collar, the number of parts increases, and the manufacturing cost increases.

[Means for solving problems]

The pivot shaft connection device for a telescopic gate according to this invention includes a hollow crosspiece with notches formed at the ends of two parallel sides, a fitting part that can be fitted into the hollow part of the crosspiece, and a fitting part of the fitting part. An edge cap having an edge closing part having the same shape as the edge of the crosspiece formed at one end, a collar part protruding from two sides of the insertion part and having a pivot shaft insertion hole penetrated through the center, and a vertical beam, etc. It consists of a pivot shaft, the fitting part of the edge cap is fitted into the hollow part of the crosspiece, and the collar part is fitted into the notch,
The pivot shaft is inserted into the pivot shaft insertion hole.

The edge is closed only by the edge cap, and the pivot shaft is surrounded by the collar, allowing smooth rotation of the crosspiece.

〔Example〕

This invention will be explained in detail below based on an embodiment shown in the drawings.

What is shown in Fig. 2 is a telescopic gate, in which a plurality of horizontal horizontal bars are successively crossed in an X-shape, and the vertical bars, which are the pivot shafts 2, are placed at the ends of the horizontal bars 1, facing each other vertically. It is inserted through the intersection of the two parts. The horizontal bar 1 rotates around the vertical bar 2, and the intersecting angle of the crossed horizontal bars 1, 1 changes, making the whole horizontally expandable and retractable.

Telescoping gates have vertical bars 2 located at either the left or right end.
is attached to one gate post 4 by hinges 3,3. 5 is a caster that supports the telescopic gate and enables smooth opening and closing.

The horizontal beam 1 is a hollow member having a substantially rectangular cross section and a hollow portion 6. Approximately rectangular notches 7, 7 are provided on two parallel sides of the end of the horizontal crosspiece 1, in the embodiment, the upper and lower surfaces.
is formed. Two sides parallel to the longitudinal direction of the horizontal beam 1, which are the outer peripheries of the notches 7, 7 on the upper and lower surfaces, are left slightly. A rivet insertion hole 15 is bored in the upper surface of the horizontal crosspiece 1 at a position slightly closer to the middle than the notch 7.

Reference numeral 8 denotes an edge cap, which is made of synthetic resin in the embodiment. The small cap 8 is the hollow part 6 of the horizontal crosspiece 1.
It has a fitting part 9 that can be fitted into the hollow part 6, and the longitudinal cross-sectional shape of the fitting part 9 is the same shape and size as the cross-sectional shape of the hollow part 6. A fitting part 9 is provided at one end of the small cap 8.
An edge closing portion 10 is formed that extends slightly toward the outer periphery and has the same shape and size as the edge of the horizontal crosspiece 1. Notches 7, 7 are provided on the upper and lower surfaces of the fitting portion 9, respectively.
Collar part 1 of approximately rectangular shape slightly larger in size than
1 and 11 are provided protrudingly. A constricted portion 12 is formed on the outer periphery of the collar portion 11 on the side of the insertion portion 9, the width of which is slightly smaller. The constriction part 12 is recessed on the opposite side of the collar part 11 from the edge closing part 10 and on two sides parallel to the longitudinal direction of the insertion part 9, and the cross-sectional shape passing through the constriction part 12 has the same shape as the notch 7. , are the same size. A pivot shaft insertion hole 13 is formed vertically through the collar parts 11, 11. A rivet fixing hole 14 is recessed in the upper surface of the insertion part 9 of the edge cap 8 at the end opposite to the edge closing part 10.

The edge cap 8 as described above is placed at the end of the horizontal bar 1,
It is attached by fitting the fitting part 9 into the hollow part 6. The outer peripheral portions of the notches 7, 7 fit into the constricted portion 12 of the collar portion 11, and the cut portion of the upper surface of the horizontal beam 1 is covered and hidden by the collar portion 11, resulting in a good appearance. The edge of the horizontal crosspiece 1 is hidden by the edge blocking part 10, resulting in a good appearance.

A rivet 16 is inserted into the rivet insertion hole 15 of the horizontal bar 1.
is inserted into the rivet fixing hole 1 of the edge cap 8.
It is fixed within 4.

A cylindrical vertical bar serving as the pivot shaft 2 is inserted into the pivot shaft insertion hole 13 of the edge cap 8 .

Although this invention has the above-mentioned configuration, other embodiments such as the following can be considered.

As the crosspiece 1, a diagonal crosspiece of a telescopic gate in which a plurality of vertical crosspieces are connected by a diagonal crosspiece can also be used.

Further, as the pivot shaft 2, a shaft member that connects diagonal members to each other can also be used.

Furthermore, instead of fixing the edge cap 8 with the rivet 16, an embodiment as shown in FIG. 5 can also be adopted. That is, the tip of the fitting portion 9 is hollow, and locking portions 17 are provided on the upper and lower surfaces of the fitting portion 9 so as to gradually increase in height from the tip side of the fitting portion 9, respectively. Horizontal beam 1
Through-holes 18 are formed in the upper and lower surfaces of each. When the fitting part 9 is inserted into the hollow part 6 of the horizontal beam 1, the locking parts 17, 17 are locked in the through holes 18, 18, and the edge cap 8 is fixed.

[Effect of idea]

The pivot shaft connection device for a telescopic gate according to this invention has the above-mentioned configuration, and can be completed simply by attaching the edge cap, which has the edge closing portion and the collar portion through which the pivot shaft insertion hole is passed, to the hollow crosspiece. In addition to closing the small opening, the pivot shaft is surrounded by a collar part to enable smooth rotation of the crosspiece.

Therefore, it is possible to reduce the number of parts, save labor in assembly, and reduce manufacturing costs.
