JPH0721940U - Separately assembled plastic fence and independent flexible legs for standing vertically - Google Patents

Abstract

(57) [Summary] (Correction) [Purpose] Establish the boundary between the work site and the walkway reliably and easily to ensure safety. Ensure a colorful and tidy work environment. Streamline maintenance, aim to save resources, save space, and improve environmental conservation. [Structure] The fence 1 is assembled by combining four units that can be joined in left-right and up-down symmetry. The flexible leg rods 2 arrange them neatly even on rough terrain.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a light-duty fence for temporary, temporary, and temporary partitioning, partitioning, and enclosure at construction sites, events, factories, and the like, and more specifically, to a method for creating and installing the fence. .

[0002]

[Prior art]

 The material of the fence is the same as that of plastic, but the conventional one is made by integral molding, including the legs.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. Since the legs are protruding, this part was particularly damaged due to impact during use, installation, transportation, storage, etc., so it was cheap.

When other parts including the leg bar are damaged, partial repair is impossible, and it is necessary to discard the whole one. This not only increased the financial burden on users, but also became a waste of industrial waste that was difficult to dispose of, and also led to the waste of petroleum resources.

Since the leg bars are integrally molded and fixed, in order to stand the fence vertically, a pedestal (weight) must be placed horizontally on the ground surface, but in many cases, even if it looks horizontal, it is slightly delicate. It was always uneven, so it was difficult to arrange fences neatly.

Due to the integral molding, one fence could be manufactured in only one color.

[0007] Since one piece is integrally molded, the die manufacturing cost is high.

An extra space was consumed during storage and transportation due to the protrusion of the leg bar.

[0009]

[Means for solving the problem]

 The legs, which are most likely to be damaged, were separated and made of iron.

The main body portion was composed of four-divided units, and the fence was a method of assembling this.

Partial damage allows only the unit containing it to be replaced, with minimal repair costs, disposal and resource consumption.

A flexible joint was inserted in the middle of the separated and independent leg bar so that it could be bent. This made it possible to stand the fence vertically even if the pedestal was not horizontal.

Since it is composed of four parts, it is possible to freely combine colors within four colors.

For the four parts, only one unit is arranged symmetrically with respect to the left and right, and vertically with respect to each other, and it is sufficient to manufacture one mold for one unit.

[0015]

【Example】

 As shown in Fig. 2, four units molded from one mold are placed symmetrically and vertically.

The protrusions and recesses (14, 15) for alignment are aligned and joined with rivets or bolts or an adhesive or the like.

When the main frame is a box type, simply inserting the inner cylinder completes the joining of this portion. (Figure 4)

When installing fences, first, the pedestals (3) are installed at fence intervals.

Next, the leg bar (2) is inserted into the pedestal. At this time, if the pedestal is horizontal, the leg bar may not use refraction, that is, the longer one may be inserted into the pedestal and the bending part may be set so as to enter the cylinder (8) of the fence.

If the pedestal is not horizontal, insert the shorter leg into the pedestal so that the longer one is vertical.

If only the above method 0020 is used, the entire fence becomes unstable, so it is better to mix the method 0019 everywhere.

When the fence is stood, the connecting metal fitting (13) is inserted into the cylinder and connected to the adjacent fence to improve stability.

When the pedestal is not horizontal, the distance between the leg bars and the adjacent leg bar becomes narrower. Therefore, adjust the pipe distance of the connecting metal fitting (FIG. 11) and set the fence so that it is vertical.

In the case of surrounding the entire area at a construction site or the like, in order to secure an entrance / exit, one leg bar may be removed.

When the fences are stacked and set, it is possible to stack not only two stacks but also ones divided into upper and lower half parts (FIG. 14). In this case, it is advisable to remove the pipe from the connecting metal fittings and attach the flat metal fittings as shown in FIG.

[0026]

[Effect of device]

 With the present invention, the most damage of the legs is almost eliminated.

In the case of damage, replacement of the unit can be repaired. Compared with conventional total waste disposal, this contributes significantly to resource conservation and environmental protection, and also reduces the financial burden on users.

With the bendable flexible leg rod according to the second aspect, the fences can be arranged vertically and neatly even on an uneven surface with an inclination of 14 degrees or less.

The flexible rod

As described above, since it can be used as a straight rod, it can be installed parallel to the slope of a slope as in the past even on a slope having a constant slope.

Since the die cost is low, it is particularly suitable for small lot production and multicolor production.

By changing the color of the unit, a colorful and beautiful fence arrangement became possible.

Since there is no leg bar, space is not consumed during storage and transportation, and handling is easy.

If the cylinder (8) of the leg bar insertion part has a slight crack, the fence can be turned upside down and used for the time being.
