Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for connecting the upper horizontal beam of a fence, handrail, etc. to a support.

Prior Art As shown in Japanese Utility Model Application Publication No. 52-171845, a through hole is formed in the wall facing the hollow support, and a U-shaped receiving bracket into which the upper horizontal beam is fitted has a locking member that engages with the through hole. A device that connects the upper horizontal beam to the support by forming a stopper and snap-fitting the receiving metal fitting to the support.

Problems that the invention aims to solve: Since the upper horizontal crosspiece is simply fitted into the U-shaped part of the receiving metal fitting, the upper horizontal crosspiece does not come into close contact with the receiving metal fitting, and the upper horizontal crosspiece does not fit tightly against the receiving metal fitting. It moves slightly and makes a rattling sound.

Means and operation for solving the problem: The upper horizontal beam is brought into contact with the first vertical plate of the support, and the two are connected by a connecting device, and between the upper horizontal plate of the connecting device and the upper wall of the upper horizontal beam. The bottom wall of the upper crosspiece is crimped to the upper crosspiece support part of the connecting tool through the elasticity imparting part of the holder that is engaged with the column, and the upper crosspiece is connected to the column, so that the upper crosspiece is connected to the connecting tool. It is designed so that it does not move even slightly.

Embodiment FIG. 1 is a front view of a fence, in which upper and lower cross beams 2, 3 are installed on a support column 1, and the upper and lower cross beams 2,
A plurality of lattices 4 are attached between the grids 3 to constitute a fence.

FIG. 2 is an exploded perspective view of the connecting part between the support 1 and the upper horizontal support 2, in which the support 1 has a pair of facing first vertical plates 1a, 1a and a pair of facing second vertical plates 1b, 1.
b, it becomes a hollow elongated material with a rectangular cross section, and the upper horizontal beam 2 becomes a hollow elongated material with a rectangular cross section by the both side walls 2b, 2b facing the bottom wall 2a, and the upper wall 2c,
In addition, a projecting strip 5 is integrally formed on the bottom wall 2a in the longitudinal direction, and one side wall 2b is formed with the support 1.
A part of the upper crossbar mounting portion of one of the first vertical plates 1a of the support 1 is cut inward to form an engaging piece 6. ing.

Reference numeral 10 denotes a connector, and this connector 10 is a vertical plate 1 with one longitudinal end of the upper horizontal plate 11 bent downward.
2 and a lower horizontal piece 13 formed by bending the lower end of the vertical plate 12 inward to form a substantially U-shape, and the upper horizontal plate 11
A substantially U-shaped upper horizontal support portion 14 is formed by the portion 11a near one end in the longitudinal direction, the vertical plate 12, and the lower horizontal plate 13, and the distance _H1 between the upper horizontal plate 11 and the lower horizontal plate 13 is It is slightly larger than the distance between the upper wall 2c and the bottom wall 2a of the upper crossbar 2, that is, the height _H2 .

A downwardly bent piece 16 is provided at the other end in the longitudinal direction of the upper horizontal plate 11, and a pair of downwardly bent pieces 16 are provided on both sides in the width direction of the portion 11b near the other end in the longitudinal direction of the upper horizontal plate 11 adjacent to the downwardly bent piece 16. Bending piece 15,1
5, and this pair of downwardly bent pieces 15,
15 is tightly attached to the outer surface of the pair of second vertical plates 1b, 1b of the column 1, and the downwardly bent piece 16 is closely attached to the other first vertical plate 1a of the column 1, so that the connector 10 is attached to the upper end of the column 1. At the same time, each downwardly bent piece 15,1
A portion of 5, 16 is cut inward to form the contact piece 1.
7, and this contact piece 17 is arranged to abut on the upper end surface of the pair of second vertical plates 1b, 1b of the support column 1 and the upper end surface of the other first vertical plate 1a.

At one longitudinal end of the insertion plate 22 inserted between the upper wall 2c of the upper horizontal beam 2 and the upper horizontal piece 11 of the connector 10, there is an elastic part 20 that provides elasticity in the vertical direction.
is formed, the other longitudinal end of the insertion plate 22 is bent downward to become a locking piece 21, and the lower edge of the locking piece 21 is folded upward inward to form a hook portion 21a. It is provided as a holder 31. The insertion plate 22 of the holder 31 is connected to the lower surface of the portion 11a nearer to one side in the longitudinal direction of the upper horizontal plate 11 and the upper wall 2 of the upper horizontal plate 2.
The holder 31 is positioned and fixed so that the hook portion 21a of the locking piece 21 engages with the engaging piece 6.

Reference numeral 23 denotes a hook provided on the locking piece 21. A hole 24 is formed in the upper horizontal plate 11 opposite to the hook 23, and a cap 25 is removably fitted into the hole 24.

Because of this, the upper horizontal beam 2 is attached to the lower horizontal plate 13 of the connecting tool 10 by being crimped by the elasticity imparting portion 20, and the hook portion 21a of the locking piece 21 is attached to the engaging piece 6 of the support column 1. Because of the engagement, the upper crossbar 2 can be connected to the column 1 as shown in FIGS. 3, 4, and 5.

At this time, the bottom wall 2a of the upper crosspiece 2 is supported by the elasticity imparting part 20 by being crimped to the lower horizontal plate 13 constituting the upper crosspiece support part 14 of the connector 10, so there is no slight movement and no rattling. There is no such sound.

Further, the hook portion 21a of the locking piece 21 and the engaging piece 6 are engaged within the support 1, and the engaging portion is not visible from the outside, resulting in an excellent appearance.

Further, the upper crosspiece 2 can be removed from the support 1 by removing the cap 25, engaging a screwdriver or the like with the hook 23 through the hole 24, and separating the locking piece 21 from the engaging piece 6.

In addition, as shown in FIG.
The lower projecting piece 3a is locked and connected to the bent portion 30a.

Effects of the invention The upper crosspiece 2 can be connected to the column 1 without using screws or the like by the connecting tool 10, and the upper crosspiece 2 can be crimped to the upper crosspiece support part 14 by the elasticity imparting part 20 of the holder 31. Because it is supported by the base, there is no slight movement and there is no rattling noise.
