Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a connector used to attach a support leg to a fence-like object such as a metal fence or handrail.

Conventional technology There are various structures for metal fences and handrails, but in general, upper and lower frames are constructed between the left and right columns,
Many of them have vertical bars installed in a row. In addition, as shown in FIG. 3 used to explain the embodiment described later, a window W with an opening at the top end is provided in the concrete block wall.
A fence-like body F may be erected between the pillars S, S on both sides by brackets A, A at both left and right ends, or by sandwiching them.

In any case, in a metal fence-like body, between both ends, that is, in the fence-like body F, if the distance between the pillars S and S is long, the middle part will bend and become unstable. A support leg L is attached for reinforcement.

FIGS. 1 and 2 show a structure for attaching a support leg L to a fence F in a conventional metal fence, which is disclosed in Japanese Utility Model Publication No. 32299/1983. According to this, the lower frame 3 of the fence-like body F is provided with a connecting groove 3a whose bottom surface is open, and the connecting groove 3a is provided with an open bottom surface.
Latching pieces 3b, 3b are provided protrudingly from both inner surfaces of the support leg L, and a pair of left and right bis pockets 2a, 2a are formed on the support leg L. When attaching the supporting leg L, attach the fixing plate 2b, which has a length that protrudes from the left and right to the upper end, with the screws 2.
c, 2c, while the connecting groove 3 of the lower frame 3
Insert the auxiliary fixing plate 3c into a, and attach the latching pieces 3b, 3.
b. Next, by screwing separate screws 4, 4 into the auxiliary fixing plate 3c from both ends of the fixing plate 2b and tightening them, the fixing plate 2b and the auxiliary fixing plate 3c are tightened.
The latching pieces 3b, 3b are pinched together, and the supporting leg L is fixed by this pinching force.

Conventionally, in order to attach the support leg L to the lower end of the fence in this way, many parts including the fixing plate 2b, the auxiliary fixing plate 3c, and the screws 2c, 2c, 4, and 4 are required, and the cost is high due to the number of parts. Not only that, but it takes a lot of time to screw in the screws, and it is also necessary to insert the auxiliary fixing plate 3c into the lower frame 3 before assembling the fence, which reduces the efficiency of the installation work of the supporting legs L. It had a very bad drawback.

Purpose of the invention In view of the fact that supporting legs are attached to metal fence-like objects such as fences using the method described above, the purpose of this invention is to provide a method that does not require any screw-in operation when installing supporting legs. To provide a connector for a support leg in a metal fence-like body, which can be attached even after the fence-like body is installed and does not require any separate parts.

Structure of the invention The structure of this invention to achieve the above-mentioned purpose is that a connecting groove is provided on the lower surface of the lower frame of the metal fence-like body, and latching pieces are arranged opposite to each other on both sides of the opening of the connecting groove. The premise is that the supporting legs that protrude and receive the load of the fence-like body are hollow members. As for the connector for connecting the lower frame and the supporting legs, a joint leg that fits into the supporting legs of the fence-like body is provided protrudingly in the center of the board that receives the load of the fence-like member on the lower surface of the lower frame, and An elastic rod-shaped piece that can be bent into the extraction groove is formed by providing an extraction groove along the edge of the elastic rod-shaped piece, and a projecting edge is provided in the middle between the two ends of the elastic rod-shaped piece. , when the other end edge of the substrate is hung on one of the hooking pieces of the connecting groove and the protruding edge is pressed against the other hooking piece, the protruding edge is elastically deformed together with the elastic rod-like piece. , the gist is that it can be hooked onto the hook.

Embodiment FIGS. 3 to 10 show an embodiment, in which the connecting tool P connects a substrate 10 that receives the load of a metal fence F on the lower surface of the lower frame 5, and It consists of a joint leg 20 that hangs down from the center and is fitted into the support leg L (Fig. 4), and the whole is integrally molded from synthetic resin.

The fence-like body F is a concrete block wall pillar S,
This is an aluminum alloy fence constructed between pillars S and S (Fig. 3), with support legs L erected on block B at the lower edge of window W between pillars S, and fence-like bodies F placed at appropriate intervals. It is supported by supporting legs L, and the lower frame 5 and supporting legs L are connected by a connecting tool P (FIGS. 4 and 5).

The lower frame 5 is formed to have a hollow square cross section, and a connecting groove 6 is provided by protruding extension pieces 5b, 5b of both side walls 5a, 5a on the lower surface. Hooking pieces 6a, 6a are provided protrudingly. Further, on the upper surface of the lower frame 5, an upright piece 7 is provided protrudingly provided at the center of the width, and the vertical beam 8 of the fence-like body F is connected to it by screws 8a.

The support leg L is formed hollow with a square cross section, and has a bis pocket 9 protruding from one side inner surface. but,
This is because another member is used as the support leg L, and the bis pocket 9 is not necessarily required.

The connector P connects the lower frame 5 and the support leg L, and the base plate 10 is a substantially square plate.
A thin rod-like piece 12 is formed by providing a groove 11 along the edge of one side end, and the rod-like piece 12
A protruding edge 13 is provided at the center between both ends on the outer surface of the holder, and regulating pieces 14, 14 that protrude shorter than the protruding edge 13 are provided at both ends (FIGS. 4 and 6). Furthermore, a notch 15 is provided between the extraction groove 11 and the connecting leg 20 to allow the extraction groove 11 to pass through, and the end of the supporting leg L is fitted onto the lower surface of the board 10 along the periphery of the connecting leg 20. A round groove 17 is formed (FIGS. 8 and 9).

The protruding edge 13 of the rod-shaped piece 12 and the end edge 16 on the opposite end thereof each have a tapered cross-sectional shape with a smaller thickness toward the tip edge, and curved slopes 13a and 16a are formed on the upper surface, and curved slopes 13a and 16a are formed on the lower surface. Direct slope 13b, 1
6b are formed respectively. Further, vertical slopes 14a, 14a are formed on the upper surfaces of both regulating pieces 14, 14 (FIG. 4).

The connecting leg 20 is formed into a U-shape in cross section so that the bis pocket 9 of the supporting leg L is accommodated therein, and on both ends of the U-shape, vertical protrusions 21, 21 are provided to facilitate press-fitting into the supporting leg L. In addition, slopes 22, 22, etc. are formed at the tip so as to become narrower toward the tip, in order to facilitate press-fitting into the support leg L. Surface protrusion 2
1 and 21 (Figure 9).

When using the above-mentioned connector P, the support leg L can be attached even after the fence F is installed between the pillars S, S of the block wall. Next, the installation procedure will be explained.

First, the connecting tool P is attached to the upper end of the supporting leg L. In this case, the connecting leg 20 of the connecting tool P can be simply press-fitted into the inside of the supporting leg L.

Next, the board 10 is attached to the connecting groove 6 of the lower frame 5 of the fence-like body F.
As shown in FIG. 10, the procedure is as shown in FIG.
0, insert the opposite end edge 16 into one end of the connecting groove 6, hook it on the hook 6a on that side, pull up the support leg L using it as a fulcrum, and then attach the board. 10 horizontally, press the protruding edge 13 onto the other hooking piece 6a from below. Edge part 13
Since the upper surface is a curved slope 13a, the rod-like piece 12 is pushed against the protruding edge 13 by the reaction of the pressing on that surface.
At the same time, the protruding edge 13 bends toward the removal groove 11 against the elastic force, so that the protruding edge 13 gradually enters the inside of the latch piece 6a, and at the same time as its tip passes the tip of the latch piece 6a, the protruding edge 13 is elastically restored together with the rod-like piece 12. Due to this restoration, the protruding edge 13 is
It goes inside a and gets caught. At the same time, the regulating pieces 14 provided on both sides of the projecting edge portion 13,
Since the distal end surface of 14 abuts against the distal end surface of the hooking piece 6a, this abutment also restricts the opposite end edge 16 from coming off the hooking piece 6a.

The upper surface of the edge portion 16 is a curved slope 16a,
Since the curved slope 16a of the supporting leg L smoothly rubs against the lower surface of the lower frame 5 while the supporting leg L is being raised, the end edge 16 is difficult to come off from the hooking piece 6a during the raising operation, and the projecting edge Since both lower surfaces of the portion 13 and the edge portion 16 are vertical slopes 13b and 16b, the board 10 is attached to the hooking piece 6.
As a result, the upper surface of the connecting tool P is brought into close contact with the bottom surface of the connecting groove 6.

With the above operations, the board 10 is connected to the connecting groove 6 of the lower frame 5.
Inside, the connecting tool P is fitted in a stable state that prevents not only widthwise displacement but also vertical movement, and there is no risk that the connecting tool P will come off from the connecting groove 6 unless special force is applied. The attachment of the supporting leg L to the lower frame 5 is now complete, and the lower end of the supporting leg L is fixed by filling the groove 25 of the block B with mortar 26 (FIG. 5). If the block B is made of Oya stone, a recess is provided in place of the groove 25 at the position where the supporting leg L stands, and the lower end of the supporting leg L is similarly fixed with mortar. Of course, this fixing means may be any other method.

Effects of the invention As explained above, according to this invention, the connecting device for connecting the lower frame of the fence-like body and the supporting legs for supporting the load is provided in the connecting groove provided in the lower frame of the fence-like body. It can be easily connected by simply hanging one edge of the board on one side of the hanging piece and pressing the protruding edge of the other end against the other side of the hanging piece, and it is also easy to connect with the supporting leg. Since no screws are used to connect the support legs, the work efficiency for attaching the support legs can be greatly improved.In addition, the installation of the support legs can be completed by simply completing the work after installing the fence-like structure, and there are no parts required other than the connectors. It has the excellent effect of not
