Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to fences.

[0002]

2. Description of the Related Art Conventionally, there are various fences, and as one of the general fences among them, a lattice fence in which a vertical member and a horizontal member are combined in a lattice shape is known. In such a lattice fence, a reinforcing material called a furring strip is usually attached to the upper and lower ends of the fence body, and the reinforcing material and the support are connected by a connecting tool.

[0003]

However, the strength of the conventional lattice fence is insufficient, and especially the strength in the thickness direction is weak. Therefore, it is necessary to attach the above-mentioned furring strip to increase the strength. As a result, the weight of the furring strip becomes heavy, resulting in a structure that is disadvantageous in terms of strength, and the number of working steps such as manufacturing and mounting of the furring strip is increased, resulting in high cost. Further, there is a problem in that it is not good in terms of aesthetics. In order to solve such a problem, the present applicant has already proposed and put into practical use various types of fens with enhanced strength of the fens body itself. An object of the present invention is to provide a fence having a new structure that is lightweight, has high strength, and is easy to manufacture and install.

[0004]

In order to achieve the above object, the fence of the present invention comprises a plurality of vertical members arranged substantially in parallel with each other and alternately bent at a predetermined interval to connect the respective vertical members. As described above, a horizontal wire member fixed to each vertical member and a horizontal member that is alternately bent at a predetermined interval and is attached to an appropriate position of the vertical member and has a greater strength than the horizontal wire member. And

[0005]

A plurality of vertical members arranged substantially parallel to each other, a horizontal wire member which is alternately bent at a predetermined interval and fixed to each vertical member so as to connect the vertical members, and further at a predetermined interval. The strength in the thickness direction is strengthened by the cross members which are alternately bent and are attached to the vertical members at appropriate positions and have high strength. Further, by using a cross member having high strength, a furring strip is not necessary.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a structure of a fence according to an embodiment of the present invention, which is configured to be installed at a predetermined place by connecting the fence to a column by an appropriate fitting.

It has a triangular waveform. In this embodiment, the cross member 3 has a diameter approximately twice that of the vertical member 2, and the cross member 3 maintains its strength and replaces the furring strip. A pipe material or the like can be used as the horizontal member 3, and the diameter thereof can be about 2 to 10 times the diameter of the horizontal wire member 1 depending on the required strength.

Further, the bent shapes and pitches of the horizontal members 3 and the bent shapes and pitches of the horizontal wire members 1 do not necessarily have to match, and each may have its own shape and pitch. It is desirable to have a combination of shapes and pitches so that the can be fixed to the cross member 3.

As shown in FIG. 3, it is desirable that the horizontal member 3 is provided on an extension of the center line S of the vertical member 2, and the center line S of the vertical member 2 is preferably provided.
It is desirable to position the center line C of the cross member 3 on the extension line of and weld them together. With such a configuration, it becomes possible to have a large strength against a load from above. FIG. 3B shows an embodiment in which a vertical member is fixed to the side portion of the horizontal member 3, and such a configuration can be adopted.

Further, FIG. 5 is a plane cross-sectional view showing the positional relationship between the horizontal wire 1 and the vertical wire 2. In this embodiment, the horizontal member 3 and the horizontal wire member 1 are bent with the same shape and pitch, and their phases are substantially the same. As described above, the vertical member 2 is welded directly below the center line C of the horizontal member 3, and is fixed to the top and the recess of the bent portion 10 of the horizontal wire 1 by welding or the like.

The lower end portion of the fence has exactly the same structure, and the lower end surface of the vertical member 2 is in contact with the horizontal member 3 and welded.

Various combinations of the shape of the horizontal member 3 and the vertical member 2 can be adopted, and the shape of the fence varies depending on the form. For example, in the embodiment shown in FIG. 6, the vertical members 2 are arranged on the triangular slopes of the horizontal members 3, and in the embodiment shown in FIG. 7, the vertical members 2 bend with the triangular slopes of the horizontal members 3. And the section.

Although the horizontal member 3 and the horizontal wire member 1 are bent in a triangular wave shape in the above embodiment, they can be bent in a smooth curved shape as shown in FIG. It is also possible to bend it into a rectangle as shown in FIG.
As shown in 0, it is possible to adopt various modes such as bending into an irregular shape.

11 and 12 show an embodiment in which a round pipe is bent and used as a cross member 3 '. This horizontal member 3'is about 8 times the diameter of the horizontal wire 1.

FIG. 13 shows an embodiment of a tall fence, in which three horizontal members 3 are arranged not only at the upper and lower ends but also at the intermediate portion. In this case, the vertical member 2 is fixed to the lateral portion of the horizontal member 3 as shown in FIG. 3B.

Although a wire rod is used as the vertical member 2 in this embodiment, a rod having a large diameter or a pipe may be used. In that case, since the strength is increased, it is possible to reduce the number of the horizontal wires 1 or to omit the horizontal wires 1 in the middle portion.

In the embodiment shown in FIG. 14, the horizontal member 3 "is composed of two wire members, and the vertical member 2 is sandwiched between the two horizontal members 3" and fixed. The horizontal member 3 ″ may have the same diameter as the horizontal wire member 1 or may have a larger diameter or a smaller diameter as required. Thus, by using the two horizontal members 3 ″, an effect of improving strength can be obtained. be able to. The pair of horizontal members 3 "can be arranged at appropriate positions at the upper and lower ends of the fence or in the middle portion, if necessary.

According to the structure described above, the strength of the entire fence is increased by the bent horizontal member 3, the horizontal wire 1, and the vertical member 2. Since the cross member 3 plays the role of a furring strip, it is possible to set up the fence by connecting the cross member 3 and the support, the structure is extremely simple, and the workability is high. Further, in the case of the structure in which the top end surface of the vertical member 2 is welded to the horizontal member 3, the end surface of the vertical member 2 does not rust, and the strength and aesthetics are less deteriorated. In addition, by bending the horizontal member 3 and the horizontal wire member 1, the fence X has a three-dimensional shape having a thickness and has a good appearance, and the thickness of the fence can be freely set depending on the bending degree. Greater freedom. Further, although the fences have such a three-dimensional shape, the fences can be stacked compactly, so that the storage and transportation efficiency is improved.
