[Embodiment of the invention]

 Hereinafter, preferred embodiments of the assembly fence according to the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, the assembling fence of this embodiment is constructed by supporting a horizontal member 20 of a metal pipe with a pair of supporting legs 22a and 22b. The supporting legs 22a and 22b are formed of metal rods, and a pair of supporting legs 22a and 22b formed in the same shape face each other, and the horizontal members 20 are supported by the supporting legs 22a and 22b. I have.

FIG. 2 is a front view of an assembling fence assembled by supporting the horizontal member 20 by supporting legs 22a and 22b. Cross member support portions 24a and 24b for supporting the cross member 20 are fixed to the upper portions of the support legs 22a and 22b. In the embodiment, as the horizontal member supporting means, the horizontal member supporting portions 24a and 24b formed in a cylindrical shape for inserting the pipe-shaped horizontal member 20 are installed.

FIGS. 3 (a), 3 (b) and 3 (c) are a front view, a side view and a plan view of the supporting legs 22a and 22b. The supporting legs 22a and 22b of the embodiment are formed by bending a metal bar. The support legs include an upper support arm 26 that supports the support members 24a and 24b, two legs 28a and 28b whose upper ends are connected to the base end of the upper support arm 26, and that opens downward. Bottom members 30a, 30b connecting the lower ends of the base members 28a, 28b, and a hook 32 connecting the connection between the bottom members 30a, 30b at the midpoint of the base and the other end of the upper support arm 26. .

As shown in the front view of the support leg (FIG. 3A), the upper support arm 26 is bent perpendicularly to both of the legs 28a, 28b, and one side from the upper ends of the legs 28a, 28b. Extend to In this embodiment, a metal pipe used for a scaffolding or the like is used as the horizontal member 20, and therefore, the horizontal member supporting portions 24a and 24b are formed in a short cylindrical shape through which the metal pipe can be inserted. The horizontal support members 24a and 24b are fixed to the upper support arm 26 by welding. The two tubular member supporting portions 24a and 24b formed in a cylindrical shape are spaced apart from each other so that the moment generated in the axial direction of the member 20 can be absorbed by changing into a couple. is there.

The stick 32 is used to reinforce and support the upper support arm 26 extending to one side from the upper ends of the legs 28a and 28b. The brace 32 connects the distal end of the upper support arm 26 and the connecting portion of the bottom members 30a, 30b to form a triangular structure as shown in FIG. doing.

The bottom members 30a, 30b connect the lower ends of the legs 28a, 28b to form a triangular structure with the legs 28a, 28b and the bottom members 30a, 30b to reinforce the legs 22a, 22b. At the same time, it supports the lower end of the brace 32 and acts to reinforce the entire supporting legs 22a and 22b. As shown in FIG. 3 (b), the bottom members 30a and 30b are arranged such that their connection portions are separated from the ground surface by a height h. The reason why the connecting portions of the bottom members 30a and 30b are separated from the grounding surface is to ensure that the lower ends of the legs 28a and 28b are grounded over the unevenness of the grounding surface, and that the assembling fence is securely erected. .

Of course, the bottom members 30a, 30b may be designed to be linearly connected between the lower ends of the legs 28a, 28b. Also in this case, by connecting the midpoints of the bottom members 30a and 30b and the upper support arm 26 with the brace 32, it is possible to obtain the required strength of the legs 22a and 22b as a whole.

When assembling the assembly fence using the legs 22a and 22b of the present embodiment, as shown in FIGS. 1 and 2, the legs 22a and 22b are arranged so that the upper support arms 26 face each other, and It is possible to assemble simply by inserting the horizontal member 20 of the metal pipe into the cylindrical horizontal member support portions 24a and 24b of the cylindrical members 22a and 22b.

When the legs 22a and 22b are erected, a moment is applied to the legs 22a and 22b in the direction in which the upper support arm 26 extends, so that the legs 22a and 22b face each other and are erected. In the case where the horizontal member 20 is supported by the legs 22a and 22b, the rotational moments of the respective legs 22a and 22b act in opposite directions, and they oppose each other. The whole assembled fence is kept upright through the intermediary.

As described above, the horizontal member support portions 24 a and 24 b are inserted through the horizontal member 20, whereby the horizontal member 20 is securely supported, and the legs 22 a and 22 b are connected via the horizontal member 20. By standing up, the horizontal member 20 does not come off from the supporting legs 22a and 22b, and the entire assembly fence is securely held in the upright state.

The assembly fence of the present embodiment can be assembled simply by supporting the cross member 20 by the supporting legs 22 a and 22 b, and the cross member 20 can be supported simply by being inserted into the cross member support portion 20. It does not require any screwing operation and can be assembled very easily. In addition, if the ends of the horizontal member 20 are sufficiently protruded outward from the horizontal member support portion 24a by the supporting legs 22a and 22b on both sides, the horizontal member does not come off after assembly, which is stable. It is maintained in a state and the durability is improved.

Further, since the structure of the supporting legs 22a and 22b for supporting the horizontal member 20 is extremely simplified, the supporting members 22a and 22b can be manufactured by a simple method such as bending one long metal rod. is there. The overall configuration of the support legs 22a and 22b in the above embodiment is a one-stroke shape, and can be configured by processing one metal rod. By using such a manufacturing method, it is possible to reduce the manufacturing cost. Of course, the method of manufacturing the legs 22a and 22b is not limited to bending a metal rod. In addition, since the pair of legs 22a and 22b that constitute the assembly fence have exactly the same shape, it is only necessary to manufacture the legs having the same shape.

In addition, with respect to the removal and transportation of the assembly fence, the assembly fence of the present embodiment can completely separate the supporting legs 22a and 22b and the horizontal member 20, so that the supporting legs and the horizontal member are separated. It can be transported and is very efficient. Further, by separately supporting the support legs and the horizontal members, it is possible to prevent each member from being damaged or distorted. In addition, since a scaffold pipe or the like can be used as the horizontal member 20, it is very convenient at a construction site or the like.

As described above, the assembly fence according to the present invention is constituted by a combination of the pair of supporting legs 22a, 22b formed in a three-dimensional frame shape and the horizontal member 20, and the structure of the supporting legs 22a, 22b is as follows. Reinforcing members such as the lateral member supporting portions 24a, 24b or the brace 32 for supporting the lateral member 20 are displaced toward the other leg with respect to the standing position of the leg portions 28a, 28b, in other words. It is characterized in that it is used in such a way that the rotational moment acts on the other support leg in a positional relationship.

The configuration of the supporting leg having such a configuration is not limited to the above embodiment. 4 and 5 show another embodiment of the support leg. The support leg shown in FIG. 4 is a reinforcement that connects the lower end of the legs 28a, 28b and the upper support arm 26 in addition to the hook 32 that connects between the connection portion of the bottom members 30a, 30b and the upper support arm 26. This is an example in which members 34a and 34b are provided.

The support leg shown in FIG. 5 is an example in which reinforcing members 34 a and 34 b for connecting the lower ends of the legs 28 a and 28 b and the upper support arm 26 are provided without using the brace 32. Further, as the horizontal member supporting portion 24 fixed to the upper support arm 26, a cylindrical portion having a tube length longer than that of the embodiment and having a clearance between the horizontal member 20 is provided. As described above, when a slight clearance is provided between the horizontal member support portion 24 and the horizontal member 20, there is an advantage that the impact force acting on the horizontal member 20 can be absorbed. As described above, it is not always necessary to provide a plurality of the lateral member supporting portions 24. In addition, the shape of the horizontal member supporting portion 24 may be formed in accordance with the shape of the horizontal member 20 to be supported. I just need. In addition, any shape may be used as long as the horizontal member 20 does not come off when the horizontal member 20 is inserted, and may be a shape in which a notch such as a slit is inserted instead of a cylindrical body.

In the above-described embodiment, the support legs are formed by using a metal rod-shaped material, and the horizontal support portions 24 are fixed by welding. However, as the rod-shaped material forming the support legs, a metal pipe, an angle material, In some cases, a resin material having a predetermined strength can be used. As described above, the material itself of the rod-shaped material is not particularly limited as long as it has predetermined strength and durability.

In the above embodiment, the use as a barricade used at a construction site or the like has been described as an example. However, the assembly fence according to the present invention has a configuration in which the horizontal member 20 is supported by the supporting legs 22a and 22b. Various utilization forms are possible as objects. That is, when the horizontal member 20 is used as a support in a vegetable garden or the like, if the support is supported by a pair of legs having the same configuration as the present invention, the horizontal member can be easily supported by the legs. It becomes possible to assemble.
