Abstract

Provided is a mesh-patterned resin molded product (10) used for encasing and protecting a hollow piping member provided in a vehicle or a small ship. The mesh-patterned resin molded product (10), in a case of an ordinary state where no load is applied to the mesh-patterned resin molded product (10), includes a plurality of first resin wired portions (11) that extend parallel to each other, and a plurality of second resin wired portions (12) that extend parallel to each other in a direction respectively intersecting the first resin wired portions (11). Each of the first resin wired portions (11) and each of the second resin wired portions (12) are joined to each other on a joint portion (13) positioned at a mutual intersection portion. At the intersection portion, a direction passing through both axial centers of the first resin wired portion (11) and the second resin wired portion (12) and being orthogonal to both the axial centers is set as an orthographic projection direction P. When the first resin wired portion (11) and the second resin wired portion (12) are viewed in the orthographic projection direction P, a second surface area that is a surface area of the joint portion (13) between the first resin wired portion (11) and the second resin wired portion (12) is smaller than a first surface area that is an overlapping surface area between the first resin wired portion (11) and the second resin wired portion (12). The plurality of first resin wired portions (11) and the plurality of second resin wired portions (12) are formed of a material including a thermoplastic resin.

First claim

The invention claimed is:

1. A mesh-patterned resin molded product used for encasing and protecting a hollow piping member provided in a vehicle or a small ship, the mesh-patterned resin molded product, in a case of an ordinary state where no load is applied to the mesh-patterned resin molded product, comprising:
a plurality of first resin wired portions that extend parallel to each other; and
a plurality of second resin wired portions that extend parallel to each other in a direction respectively intersecting the first resin wired portions,
wherein each of the first resin wired portions and each of the second resin wired portions are joined to each other on a joint portion positioned at a mutual intersection portion,
wherein in a case where a direction passing through both axial centers of the first resin wired portion and the second resin wired portion and being orthogonal to both of the axial centers is set as an orthographic projection direction at the intersection portion between the first resin wired portion and the second resin wired portion which are joined to each other, when the first resin wired portion and the second resin wired portion are viewed in the orthographic projection direction, a second surface area that is a surface area of the joint portion between the first resin wired portion and the second resin wired portion is smaller than a first surface area that is an overlapping surface area between the first resin wired portion and the second resin wired portion,
wherein the plurality of first resin wired portions and the plurality of second resin wired portions are formed of a material including a thermoplastic resin, and
wherein the joint portion is partially stretched or partially ruptured.

2. The mesh-patterned resin molded product according to claim 1 ,
wherein the second surface area is equal to or less than ¾ of the first surface area.

3. The mesh-patterned resin molded product according to claim 1 ,
wherein when the hollow piping member is encased in the mesh-patterned resin molded product, the mesh-patterned resin molded product is in tight contact with the hollow piping member.

4. The mesh-patterned resin molded product according to claim 1 ,
wherein the thermoplastic resin includes any one or more selected from the group consisting of polyethylene, polypropylene, nylon, and polyethylene terephthalate.

5. A mesh-patterned resin molded product used for encasing and protecting a hollow piping member provided in a vehicle or a small ship, the mesh-patterned resin molded product, in a case of an ordinary state where no load is applied to the mesh-patterned resin molded product, comprising:
a plurality of first resin wired portions that extend parallel to each other; and
a plurality of second resin wired portions that extend parallel to each other in a direction respectively intersecting the first resin wired portions,
wherein each of the first resin wired portions and each of the second resin wired portions are joined to each other on a joint portion positioned at a mutual intersection portion,
wherein in a case where a direction passing through both axial centers of the first resin wired portion and the second resin wired portion and being orthogonal to both of the axial centers is set as an orthographic projection direction at the intersection portion between the first resin wired portion and the second resin wired portion which are joined to each other, when the first resin wired portion and the second resin wired portion are viewed in the orthographic projection direction, a second surface area that is a surface area of the joint portion between the first resin wired portion and the second resin wired portion is smaller than a first surface area that is an overlapping surface area between the first resin wired portion and the second resin wired portion,

wherein the plurality of first resin wired portions and the plurality of second resin wired portions are formed of a material including a thermoplastic resin, and
wherein the material contains carbon black which imparts stretchability to the mesh-patterned resin molded product.

6. The mesh-patterned resin molded product according to claim 1 ,
wherein the vehicle is an automobile.

7. The mesh-patterned resin molded product according to claim 1 ,
wherein the plurality of first resin wired portions are spirally wound so as to be coaxial to each other, and
wherein the plurality of second resin wired portions are spirally wound so as to be coaxial to each other and to rotate opposite to the plurality of first resin wired portions, on an outer circumferential side of the plurality of first resin wired portions.

8. The mesh-patterned resin molded product according to claim 1 ,
wherein when the mesh-patterned resin molded product is stretched in an axial direction, the mesh-patterned resin molded product reduces in diameter, and
wherein when the mesh-patterned resin molded product is stretched in a radial direction, the mesh-patterned resin molded product increases in diameter.

9. The mesh-patterned resin molded product according to claim 5 ,
wherein the second surface area is equal to or less than ¾ of the first surface area.

10. The mesh-patterned resin molded product according to claim 5 ,
wherein when the hollow piping member is encased in the mesh-patterned resin molded product, the mesh-patterned resin molded product is in tight contact with the hollow piping member.

11. The mesh-patterned resin molded product according to claim 5 ,
wherein the thermoplastic resin includes any one or more selected from the group consisting of polyethylene, polypropylene, nylon, and polyethylene terephthalate.

12. The mesh-patterned resin molded product according to claim 5 ,
wherein the vehicle is an automobile.

13. The mesh-patterned resin molded product according to claim 5 ,
wherein the plurality of first resin wired portions are spirally wound so as to be coaxial to each other, and
