Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for connecting vertical members and horizontal members constituting a panel grid, handrail, etc.

Prior Art As shown in Japanese Utility Model Publication No. 56-3513, a groove is formed in a hollow vertical member, and a horizontally protruding plate portion that fits into the groove is formed on the horizontal member, and a horizontally protruding plate portion that fits into the hollow portion of the vertical member is formed. A device is known in which a connecting shaft is provided on the mating cap, and the connecting shaft is fitted into a small hole in a horizontally projecting plate at the same time as the cap is fitted to the vertical member to connect the vertical member and the horizontal member. There is.

Problems to be solved by the invention Since the vertical members and the horizontal members are only connected by the fitting portion between the small hole and the connecting shaft, the connection strength is weak.

Since the fitting part between the connecting shaft and the small hole prevents the cap from coming off, the cap can easily come off.

Means and action for solving the problem First and second notches are formed in the wall of the vertical member at intervals in the longitudinal direction, and first and second through holes are formed in one side wall of the horizontal member. The first and second projecting pieces having the first and second protrusions are
A connecting device is provided with a leg portion formed opposite to the notch portion and having a locking portion on the head portion that closes the opening of the vertical member;
Fitting the first and second projecting pieces into the first and second notches, fitting the head into the opening of the vertical member, and fitting the leg into the first and second through holes, In addition, the locking part is locked in the through hole to prevent the connector from coming off.

Embodiment FIG. 1 is a sectional view of a connected state, and FIG. 2 is an exploded perspective view. The vertical member 1 is formed into a long member with a rectangular cross section by one opposing wall 1a, 1b and the other opposing wall 1c, 1d. It has an opening 2 at the end in the longitudinal direction, and first and second cuts are provided near the ends of one wall 1a and the other opposing wall 1c, 1d of one opposing wall 1a, 1b. Notches 3 and 4 are formed spaced apart in the longitudinal direction.

The cross member 10 is a long member with a substantially rectangular cross section by one side wall 10a, the other side wall 10b, one end wall 10c, and the other end wall 10d, and the one side wall 10a has first and second projecting pieces 1.
1 and 12 are integrally formed with the same distance as the distance between the first and second notches 3 and 4.

The first and second projecting pieces 11 and 12 are
The thickness is the same as the height of the notches 3 and 4, and the protrusion length is the same as the length of the first and second notches 3 and 4, and the first protrusion 11 has a large diameter. A first through hole 13 is provided in the second projecting piece 12, and a second through hole 14 with a small diameter is provided in the second projecting piece 12.
are formed respectively.

The connector 20 includes a rectangular plate-shaped head 21 that closes the opening 2 of the vertical member 1, and a leg portion 22 that fits tightly into the opening 2 of the vertical member 1 is integrally formed at the lower part of the head 21. , this leg portion 22 has a wedge shape in which one side 22a is vertical and the other side 22b is inclined, and the longitudinal middle part is thick and the tip is thin, and the middle part and the tip of the other side 22b are thick. First and second locking portions 23 and 24 that lock into the first and second through holes 13 and 14 are formed in the portions.

Note that only one of the first and second locking portions 23 and 24 may be formed.

Because of this, in order to connect the vertical member 1 and the horizontal member 10, insert the first and second projecting pieces 11 and 12 of the horizontal member 10 into the first and second notches 3 and 4 of the vertical member 1. Once fitted, the connector 20 is inserted into the opening 2 of the vertical member 1 and the leg piece 22 is inserted.
are fitted into the first and second through holes 13 and 14, and
It is only necessary to lock the first and second locking parts 23 and 24.

As a result, the horizontal member 10 is drawn toward the vertical member 1 side by the wedge action of the leg piece 22, and the one side wall 10
a and the wall 1a are crimped to firmly connect the horizontal member 10 and the vertical member 1, and prevent the connector 20 from coming off.

In addition, as shown by the imaginary lines in FIG.
It may be made to fit into both end walls 1c, 1d of.

In this way, the first and second notches 3 and 4 only need to be formed in the wall 1a.

Effect of the invention The leg piece 22 is connected to the first and second projecting pieces 11 and 12.
Since it fits into the second through holes 13 and 14 and presses one side wall 10a of the cross member 10 to the wall of the vertical member 1 by a wedge action, the vertical member 1 and the cross member 10 can be firmly connected.

Since the locking part is locked in the through hole, the connecting tool 20
can be prevented from escaping.
