Description

[Technical Field]

[0001] The present invention relates to a safety fence. [Background technology]

[0002] When using a brush cutter to remove weeds, various blades are commercially available and used, including chip saw blades, steel blades, and nylon cord blades. Regardless of the blade selected, when used, pebbles and other nearby solid objects are usually scattered around along with the grass clippings. When these debris are scattered, they can cause scratches on the windowpanes of houses, the body or windows of cars, and even lead to compensation issues. To solve this problem, it is desirable to use a protective fence that is not only easy to carry to the required location, but also does not easily tip over even when subjected to external forces such as wind. However, conventional protective fences are cumbersome to carry to required locations, and tend to easily fall over when subjected to external forces such as wind.

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 5-47257 Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention has been made in consideration of the above circumstances, and aims to provide a protective fence that is easy to carry and has a suitable configuration that can prevent it from falling over. [Means for solving the problem]

[0005] The invention described in claim 1 is a protective fence comprising a folding screen-shaped protective fence main body that can be changed between a folded position and an unfolded position, end legs that are attached to both ends of the protective fence main body and have their lower ends in contact with the ground, and intermediate legs that are detachable from the protective fence main body and have their lower ends in contact with the ground when attached to the protective fence main body, the protective fence main body is made up of three or more substantially rectangular fence plates that are connected horizontally via hinges, and a slit-shaped through hole that extends vertically is provided at the bottom of one of the fence plates, and the intermediate leg can be inserted into the through hole and attached to the fence plate only when the protective fence main body is in the unfolded position, and a recess that is recessed upward and open downward is provided in the middle of the longitudinal direction of the intermediate leg, and the recess can be fitted onto the lower edge of the through hole. The invention described in claim 2 is the protective fence described in claim 1, in which handles for carrying are provided on the top of the fence plates that form both ends of the protective fence body. The invention described in claim 3 is the protective fence described in claim 1, in which the intermediate leg is made of metal and also serves as a weight. [Effects of the Invention]

[0006] This invention makes it possible to provide a protective fence that is easy to carry and has a suitable configuration that can prevent it from falling over. [Brief explanation of the drawings]

[0007] [Figure 1] 1 is a perspective view showing one embodiment of the present invention (when the protective fence body is in a folded position). FIG. [Figure 2] FIG. 2 is a perspective view of the same embodiment (when the protective fence main body is in the deployed position). [Figure 3] FIG. 2 is a perspective view of the same embodiment (when the protective fence main body is in the deployed position). [Figure 4] 10 is a perspective view of an intermediate leg in the same embodiment, and a perspective view showing the attachment position of the intermediate leg to the protective fence main body. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0008] In this embodiment, the present invention is applied to a free-standing folding screen-type scattering guard fence (hereinafter simply referred to as "guard fence A"). Guard fence A can be installed anywhere depending on the space and conditions at the site of use. If there is not enough space for one guard fence A, two can be used side by side. The protective fence A is a lightweight, self-supporting structure that can be moved and carried with one hand. Therefore, the protective fence A of this embodiment does not require the support assistants that were previously required. The protective fence A can be stored and transported in a small space such as a light truck by folding the protective fence main body B into the folded position (S). When in use, the protective fence A can be used to prevent flying debris from flying towards houses or vehicles over a wide area by unfolding the folding screen-shaped protective fence main body B and changing its position to the deployed position (T). The protective fence A comprises a folding screen-shaped protective fence main body B that is capable of changing its position between a folded position (S) and an unfolded position (T), end legs 3 that are provided at both ends of the protective fence main body B and whose lower ends come into contact with the ground, and intermediate legs 5 that are detachable from the protective fence main body B and whose lower ends come into contact with the ground when attached to the protective fence main body B. The protective fence body B is made up of five roughly rectangular fence plates 2 connected horizontally via hinges H. Handles 1 for carrying are provided on the top of the fence plates 2 that make up both ends of the protective fence body B. Of the five fence plates 2, a slit-shaped through hole 4 extending in the vertical direction is provided in the lower part of the middle shelf plate 2. The intermediate legs 5 can be inserted into the through holes 4 and attached to the fence plates 2 only when the protective fence main body B is in the deployed position (T). The intermediate legs 5 are made of metal and also function as weights. A recessed portion 51 that is recessed upward and open downward is provided in the middle of the longitudinal direction of the intermediate legs 5. The recessed portion 51 of the intermediate legs 5 can be fitted onto the lower edge 41 of the through hole 4. [Explanation of symbols]
