[Figure 4] 11A and 11B are diagrams illustrating how wiring is accommodated in a wiring accommodating portion. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] The present invention will be described in more detail below with reference to the drawings, showing embodiments and specific examples, but the present invention is not limited to these embodiments and specific examples. In addition, in the following explanation using the drawings, it should be noted that the drawings are schematic and the ratios of the dimensions, etc. may differ from the actual ones, and in order to make it easier to understand, illustrations other than those of parts necessary for the explanation have been omitted as appropriate.

[0020] (1) Wiring cover configuration FIG. 1 is a perspective view showing an example of installation of a wiring cover 1 according to this embodiment, and FIG. 2 is a schematic cross-sectional view showing the structure of the wiring cover according to this embodiment. The configuration and function of the wiring cover 1 according to this embodiment will be described below with reference to the drawings.

[0021] (Overall configuration of wiring cover) As shown in FIG. 1, the wiring cover 1 is configured to include a wiring accommodating section 10 that accommodates wiring W therein from one end side to the other end side, and a wiring insertion section 20 into which the wiring W can be inserted. The wiring cover 1 configured in this manner is installed at a corner C where two surfaces (X and Y in FIG. 1) intersect to form an inside corner, and, for example, houses wiring W that is routed along the corner C of a building, and holds the wiring W inside so that it is not exposed to the outside.

[0022] (Wiring storage section) 2, the wiring housing 10 is composed of a main body 10A having a bottom surface 11 along one surface X of two surfaces of the corner portion C to be installed and a side surface 12 along the other surface Y of the two surfaces, and a cover portion 10B that covers the main body 10A and is formed of a material that is softer and more elastically deformable than the main body 10A. The main body 10A and the cover portion 10B are integrally formed by connecting the bottom surface 11 and the side surface 12 of the main body 10A at one end 11a, 12a by extrusion molding a thermoplastic elastomer resin or a soft resin having different hardness.

[0023] 2, the main body 10A has a bottom surface 11 and a side surface 12 that intersect with each other to form an L-shaped cross section, and a slit 13 is formed in the side surface 12. The slit 13 serves as a wire insertion portion 20 into which a wire W can be inserted into the wire housing portion 10.

[0024] A lip shape 11b is formed on one end 11a of the bottom surface 11. The lip shape 11b has a tapered tip 11c in a cross-sectional view, and when the bottom surface 11 of the main body 10A is fixed to one surface X of the two surfaces of the corner portion C with double-sided tape or the like, the lip shape 11b is elastically pressed against the surface X and serves as a so-called seal to prevent dust and the like from entering the bottom surface 11 side. The lip shape may also be formed on one end 12a of the side surface 12. By forming the lip shape 12b on the one end 12a of the side surface 12 as well, the lip shape 12b elastically contacts the surface Y to prevent dust and the like from entering the side surface 12 side, and the inside of the side surface 12 can be made invisible from above.

[0025] 2, the cover portion 10B is formed in a semi-arch shape so as to connect and cover the bottom surface 11 and the side surface 12 of the main body portion 10A. One end 10Ba of the cover portion 10B is connected to one end 11a of the bottom surface 11 of the main body portion 10A, and the other end 10Bb is connected to one end 12a of the side surface 12 of the main body portion 10A, so that the wiring W housed in the main body portion 10A is not exposed to the outside from the main body portion 10A.

[0026] The cover portion 10B is integrally formed with the main body portion 10A by extrusion molding. In this embodiment, the main body portion 10A and the cover portion 10B are integrally extrusion molded using two types of thermoplastic elastomers (TPEs) with different hardnesses, both of which have a type D durometer hardness of D50 or less as measured in accordance with JIS K7215, and the cover portion 10B is molded from a thermoplastic elastomer (TPE) or soft resin whose type D durometer hardness is 10 or more lower than that of the main body portion 10A.

[0027] Such resin materials include polystyrene elastomer, polystyrene, polyolefin elastomer, polyolefin, ethylene vinyl acetate copolymer, polyvinyl chloride elastomer, polyvinyl chloride, polyurethane elastomer, polyurethane, polyester elastomer, polyester, polyamide elastomer, polyamide, etc., and have a D scale hardness of 40 or less as measured by a type D durometer hardness meter. In this embodiment, a polyurethane elastomer or soft polyvinyl chloride resin having a D scale hardness of 40 or less is used. If the D scale hardness exceeds 40, the cover portion 10B becomes difficult to deform, and there is a risk that it becomes difficult to insert the wire W from the wire insertion portion 20 into the wire housing portion 10.

[0028] (Wiring insertion part) The wire insertion portion 20 is formed as a slit 13 on the side surface 12 of the main body portion 10A. The wire insertion portion 20 opens the slit 13 by deforming the cover portion 10B, which is made of a thermoplastic elastomer (TPE) or soft resin having a type D durometer hardness 10 or more lower than that of the main body portion 10A, so that the wire W can be inserted.

[0029] 2, the slit 13 is composed of a convex portion 13A and a concave portion 13B facing each other, and when the cover portion 10B is not deformed, the convex portion 13A and the concave portion 13B face each other closely. This makes it difficult for the wiring insertion portion 20 to shift, and when the main body portion 10A is pressed from above, the convex portion 13A and the concave portion 13B come into contact so as to mesh with each other, so that the pressing force is easily transmitted to the bottom surface 11 of the main body portion 10A, and the pressure is increased when the bottom surface 11 of the main body portion 10A is attached to the surface X with, for example, double-sided tape.

[0030] (2) Manufacturing method of wiring cover 1 The wiring cover 1 of this embodiment is molded by two-color extrusion molding using a thermoplastic elastomer resin that forms the main body portion 10A and a thermoplastic elastomer resin that forms the cover portion 10B, the type D durometer hardness of which is 10 or more lower than that of the main body portion 10A.

[0031] The method of forming by extrusion is not particularly limited, but as an example, the material can be produced by extrusion molding as follows. First, the thermoplastic elastomer resin forming the main body 10A and the thermoplastic elastomer resin forming the cover 10B are melted by heating and kneading at 180°C to 230°C, passed through a filtration filter, and then melt-extruded simultaneously from a metal mold die outlet heated to 180°C to 230°C, and cooled to solidify. This results in the wiring cover 1 in which one end 11a of the bottom surface 11 of the main body 10A and one end 12a of the side surface 12 are connected to the cover 10B and integrated.

[0032] (3) Installation of wiring cover FIG. 3 is a diagram for explaining installation of the wiring cover 1 at the corner portion C, and FIG. 4 is a diagram for explaining accommodation of the wiring W in the wiring accommodation portion 10. As shown in FIG. The wiring cover 1 is cut to the required length and attached with double-sided tape or the like to one surface X of a corner portion C where two surfaces X and Y intersect to form an inside corner. The wiring cover 1 according to this embodiment is extrusion molded using a thermoplastic elastomer resin having a type D durometer hardness of D50 or less as measured in accordance with JIS K7215, and therefore is easier to cut with scissors or a cutter at the construction site and easier to install than a hard synthetic resin.

[0033] The wiring cover 1 cut to the required length has its bottom surface 11 fixed to one surface X of the corner C with adhesive AD such as double-sided tape. As shown in Fig. 3, the wiring insertion portion 20 is formed as a slit 13 consisting of a convex portion 13A and a concave portion 13B facing each other on the side surface 12 of the main body portion 10A, and the convex portion 13A and the concave portion 13B face each other closely when the cover portion 10B is not deformed. As a result, by pressing the main body portion 10A from above (see arrow F in the figure), the convex portion 13A and the concave portion 13B come into contact so as to mesh with each other, and the pressing force is transmitted to the bottom surface 11 (see arrow R in the figure), and the main body portion 10A can be firmly fixed to the corner C.

[0034] As shown in Fig. 4(a), when the wires W are pressed against the upper surface 10Bc of the cover portion 10B of the wire cover 1 fixed to the corner portion C, the cover portion 10B is easily deformed since it is made of a thermoplastic elastomer having a type D durometer hardness 10 or more lower than that of the main body portion 10A, and the wire insertion portion 20 opens widely as shown in Fig. 4(b), and the wires W are accommodated in the main body portion 10A. With the wires W accommodated in the main body portion 10A, the deformed cover portion 10B returns to its original shape as shown in Fig. 4(c), and the wires W are not exposed to the outside from the main body portion 10A.

[0035] (4) Effects of Wiring Cover 1 The main body 10A and cover 10B of the wiring cover 1 are extrusion molded using two types of thermoplastic elastomer (TPE) with different hardness, both of which have a type D durometer hardness of D50 or less as measured in accordance with JIS K7215, and the cover 10B is integrally molded using a thermoplastic elastomer (TPE) or soft resin with a type D durometer hardness 10 or more lower than that of the main body 10A. This makes installation, including on-site processing, easy and facilitates the insertion of the wiring W. The wire insertion portion 20 is formed as a slit 13 on the side surface 12 of the main body portion 10A, and the slit 13 opens by deforming the cover portion 10B, which is made of a thermoplastic elastomer (TPE) or soft resin whose type D durometer hardness is 10 or more lower than that of the main body portion 10A, to allow the insertion of the wire W. After the wire W is inserted, the cover portion 10 easily returns to its original shape, and the wire W is not exposed to the outside from the main body portion 10A. The slit 13 that becomes the wiring insertion portion 20 is composed of a convex portion 13A and a concave portion 13B that face each other, and when the cover portion 10B is not deformed, the convex portion 13A and the concave portion 13B face each other closely. This makes it difficult for the wiring insertion portion 20 to shift, and when pressed from above, the convex portion 13A and the concave portion 13B come into contact so as to mesh with each other, making it easier to transmit the pressing force to the bottom surface 11 of the main body portion 10A and increasing the pressing force of the bottom surface 11. A lip shape 11b is formed at one end 11a of the bottom surface 11 of the main body 10A to prevent dust and the like from entering the bottom surface 11. By forming a lip shape 12b also at one end 12a of the side surface 12, it is possible to prevent dust and the like from entering the side surface 12 and to make the inside of the side surface 12 invisible from above.

[0036] Although the embodiment of the present invention has been described above in detail, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the gist of the present invention described in the claims. For example, the cover portion 10B may be extruded from a material of the same color as the corner portion C. By making the cover portion 10B the same color as the corner portion C, the installation of the wiring W can be made less noticeable. In addition, by making the cover portion 10B from a transparent material, the wiring W housed inside can be made visible. [Explanation of symbols]
