Abstract
Description
Technical Field
[0001] The present invention relates to a cable protector that protects cables such as electrical wiring laid on the ground of roads or the like from impacts from vehicles or the like when the vehicle or the like rides over them.
Background Art
[0002] Conventionally, cable protectors laid on the ground roads and used during construction work etc. use hollow protectors formed of a soft material and stored in a wound state. Also, protectors formed of resin or the like are provided.
[0003] For example, Patent Document 1 provides a normal temperature construction method for an embedded cable protection pipeline that can be constructed at normal temperature, has no need for temperature management and no risk of burns, has little waste of materials, and has no risk of fluidization phenomenon even when rolling pressure is applied when further constructing a surface layer on the constructed cable protection pipeline, and also provides an embedded cable protection pipeline constructed by such a normal temperature construction method.
[0004] For example, Patent Document 2 discloses an invention that provides a wire gutter that, without losing the advantages of conventional wire gutters, is excellent in strength, so that even when a vehicle passes or a heavy object is placed, the electric wire cable is not damaged, and can also cope with the case where a storage part for a large number of electric wire cables is required.

Problems to be Solved by the Invention
[0006] As shown in Patent Document 2, there are devices that use flexible materials to protect small wiring and connect them laterally to adjust the width. However, when laying cables over long distances across roads, elevated roads, or factory walkways, it is necessary to manufacture long cable protectors. However, the longer the protectors, the heavier they become, making installation extremely difficult. Furthermore, when used in road construction, quick installation and removal are required.
[0007] The coiled tubular protective devices had problems such as becoming kinked, making it difficult to thread wires through them, and curling up when placed on a flat surface. On the other hand, while resin protective devices did not have the problem of becoming kinked, the connecting parts were prone to coming loose.
[0008] The present invention was made to solve the above problems and aims to provide a cable protector that can be quickly installed and removed and can protect cables even from heavy objects. [Means for solving the problem]
[0009] A cable protector comprising a main body laid on the ground and a through-hole into which a cable can be inserted, The aforementioned main body is A sloped section formed in the shape of a mountain, through which vehicles can pass, Both ends have protruding parts on the sides, It comprises fitting grooves formed on the bottom surfaces of both ends for fitting with the aforementioned projections, The main body is characterized by being integrally molded from a soft material. [Effects of the Invention]
[0010] Due to the above features, the present invention can protect cables from heavy objects such as vehicles, and allows for quick installation. [Brief explanation of the drawing]

[Figure 7] This diagram shows how the cable protectors of the embodiment are connected. [Modes for carrying out the invention]
[0012] The lay-type marker and its manufacturing method according to the present invention will be described in detail with reference to the drawings. The embodiments and drawings described below are illustrative of some embodiments of the present invention and are not intended to limit the scope to these configurations. They can be modified as appropriate without departing from the spirit of the present invention.
[0013] First, we will explain the state in which the cable protector 10 is laid on the road 1, referring to Figures 1 and 2. The cable protector 10 is constructed by connecting multiple cable protectors 10 as shown in Figure 1. Figure 1 shows the cable protector 10 laid on the ground 1. Figure 1 shows how two cable protectors 10 are connected and how the cable 3 is protected by passing it through the inside of the cable protectors 10. Figure 2 shows how two cable protectors 10 are connected.
[0014] Next, the structure of the cable protector 10 will be described in detail with reference to Figures 3 to 6. Figure 3 is a perspective view showing the entire cable protector 10. Figure 4 is a plan view of the cable protector 10. Figure 5 is This is a bottom view of the cable protector 10. FIG. 6(A) is a sectional view taken along line A-A, and FIG. 6(B) is a sectional view taken along line B-B.
[0015] The cable protector 10 is provided with a cable through-hole 11, which is a through-hole penetrating the cable protector 10 near the center of the side surface. In addition, it has connection fitting portions 19 protruding from the side surfaces at both ends of the cable protector 10. The connection fitting portions 19 are protruding portions formed in a T-shape when viewed from the plane.
[0016] As shown in FIG. 4 or FIG. 5, the cable protector 10 is provided with a window portion 15, which is a hole penetrating from above to below. This window portion 15 enables the state of the cable 3 to be confirmed and at the same time is a hole capable of guiding the cable when passing the cable 3.
[0017] In addition, this window portion 15 is a hole for inserting a mandrel that forms the cable through-hole 11 for inserting the cable 3 and is required when extracting the mandrel. Therefore, this window portion 15 is not only necessary when inserting the cable 3 but also an essential hole during molding. Note that the window portion 15 may be provided on at least one of the peak side and the bottom side of the mountain shape of the main body. It is better to provide it on both sides of the peak side and the bottom side.
[0018] As shown in FIG. 4, FIG. 5 or FIG. 6, the cable protector 10 is provided with fixing holes 13, which are through-holes capable of being fixed to the ground 1 such as concrete or paved roads on the inclined surface 16 of the mountain shape of the cable protector 10. As shown in FIG. 6, the fixing holes 13 are further provided with insertion holes 12 smaller than the fixing holes 13. Then, bolts, nails, etc. can be inserted through the fixing holes 13 to fix the cable protector 10 to the ground 1.
[0019] Next, as shown in FIG. 3, FIG. 4 or FIG. 6, convex portions 18 are provided on the inclined surface 16 of the mountain shape of the cable protector 10. The inclined surface 16 is inclined so that the vehicle can easily drive over it. In addition, steps are formed by the convex portions 18 so that the tires of the vehicle do not slip.
[0020] As shown in Figure 5, a fitting groove 14, which is a groove that fits with the connecting fitting portion 19, is formed on the bottom surface of the cable protector 10. As shown in Figure 7, when fitting the connecting fitting portion 19 into the fitting groove 14, each of the connecting fitting portions 19 at both ends is inserted into the fitting groove 14 from below, and the cable protector 10 is inserted by rotating it upwards to complete the fitting.
[0021] To release the connection, the cable protector 10 is rotated downwards to release the connection. Multiple cable protectors 10 are connected and laid in this manner. The cable protector 10 will not easily come loose when placed on the ground 1. Thus,
[0022] The cable protector 10 shown in this embodiment uses rubber as its material, and the following types of rubber can be used. For example, styrene-butadiene rubber (SBR), natural rubber (NR), butyl rubber (IIR), nitrile rubber (NBR), ethylene-propylene rubber (EPDM), chloroprene rubber (CR), urethane rubber (PUR), silicone rubber (SI), and fluororubber (FPM) are examples, but the invention is not limited to these, and any rubber product will suffice.
[0023] Thus, the cable protector 10 is made of a soft material and the fitting structure described above, making it difficult for the fitted portion to come loose.
[0024] (Technical features) The following are some examples of the technical features of this embodiment, shown in parentheses, but are not particularly limited. These are just examples, and the effects that can be expected from these characteristics will also be described.
[0025] <Feature 1> A cable protector comprising a main body laid on the ground (for example, a cable protector 10) and a through-hole (for example, a cable through-hole 11) into which a cable (for example, a cable 3) can be inserted, The aforementioned main body is A sloped section (for example, mainly an inclined surface 16) formed in a mountain-like shape that allows vehicles to pass, Both ends have protruding parts on the sides (for example, mainly connecting fitting parts 19), It comprises fitting grooves (for example, mainly fitting grooves 14) formed on the bottom surfaces of both ends to engage with the aforementioned protrusions, The main body is characterized by being integrally formed from a soft material (for example, mainly styrene-butadiene rubber (SBR), natural rubber (NR), etc.).
[0026] Due to the above features, the present invention can protect cables from heavy objects such as vehicles and allows for quick installation. Since the entire body, including the mating portion, is made of a soft material, the units are less likely to come apart when connected to each other. Furthermore, it causes less impact to passing vehicles, etc.
[0027] <Feature 2> The main body is characterized by being formed by rotating it from bottom to top while engaging the projection with the fitting groove, and connecting multiple main bodies. Due to the above features, the present invention is designed so that when placed in a fixed position, force is applied in the direction of interlocking, making it unlikely to come loose unless lifted from the ground.
[0028] <Feature 3> The main body is characterized by having a plurality of holes, or windows (for example, mainly windows 15), on at least one side of the mountain-shaped apex side and the bottom side of the main body. Due to the above features, the present invention allows for observation of the cable's condition. Furthermore, it can improve drainage, thus protecting the cable. The window portion is a hole required during the molding process. [Industrial applicability]
[0029] Regarding the industrial use of the cable protection device 10 of the present invention, it can be used not only on general roads and highways, but also by being laid on roads within factories and facilities. [Explanation of Symbols]
