Abstract

A housing unit includes: a linear material; and a housing body that houses the linear material. In the housing body, winding regions in which the linear material is wound are disposed in a circumferential direction. The linear material is wound in a figure eight in a first region pair constituted by a pair of the winding regions. The linear material is wound in a figure eight in a second region pair constituted by a pair of the winding regions that are different from the winding regions constituting the first region pair.

First claim

The invention claimed is:

1. A housing unit comprising:
a linear material; and
a housing body that houses the linear material, wherein
in the housing body, winding regions in which the linear material is wound are disposed in a circumferential direction,
the linear material is wound in a figure eight in a first region pair constituted by a pair of the winding regions, and
the linear material is wound in a figure eight in a second region pair constituted by a pair of the winding regions that are different from the winding regions constituting the first region pair.

2. The housing unit according to claim 1 , wherein the housing body is in contact with the linear material and maintains a posture of the linear material wound in the winding regions.

3. The housing unit according to claim 1 , wherein
the housing body comprises a shaft member that is rod-shaped,
the winding regions are disposed around an outer circumference of the shaft member, and
the shaft member is in contact with the linear material wound in the winding regions.

4. The housing unit according to claim 3 , wherein
an inner wall surface of the housing body is in a polygonal cylindrical shape, and
the linear material wound in the winding regions is in contact with the shaft member and two portions of the inner wall surface of the housing body.

5. The housing unit according to claim 3 , wherein an external shape of the housing body is in a circular cylindrical shape.

6. The housing unit according to claim 5 , wherein

where
R is a radius of the housing body,
r is a bend radius of the linear material wound in the winding regions, and
N is a number of the winding regions.

7. The housing unit according to claim 3 , wherein
the housing body comprises retaining members that are rod-shaped,
the retaining members are disposed in a circumferential direction along an inner wall surface of the housing body, and
the linear material wound in the winding regions is in contact with the shaft member and two of the retaining members.

8. The housing unit according to claim 1 , wherein
the linear material is wound in a figure eight in an S-direction in one or more regions, and
the linear material is wound in a figure eight in a Z-direction in one or more regions.

9. The housing unit according to claim 1 , wherein
the linear material is wound in a figure eight in both of the first region pair and the second region pair while shifting both of the first region pair and the second region pair in a predetermined direction in the circumferential direction, and
the linear material is wound in a figure eight in both of the first region pair and the second region pair while shifting both of the first region pair and the second region pair in a direction opposite to the predetermined direction.

10. The housing unit according to claim 1 , wherein the linear material is an optical cable.

11. The housing unit according to claim 1 , wherein an intersection point of the linear material wound in a figure eight in a pair of the winding regions is disposed in one of the winding regions that is not either one of the pair of the winding regions.

12. The housing unit according to claim 1 , wherein an intersection point of the linear material wound in a figure eight in the first region pair is displaced in the circumferential direction from an intersection point of the linear material wound in a figure eight in the second region pair.

13. The housing unit according to claim 1 , wherein the first region pair and the second region pair include a common winding region.

14. A wound body formed by winding a linear material, the wound body comprising:
circular arc parts in which the linear material is wound in a circular arc shape, wherein
the circular arc parts are disposed in a circumferential direction,
a pair of the circular arc parts constitutes a first circular arc pair in which the linear material is wound in a figure eight, and
a pair of the circular arc parts that are different from the circular arc parts constituting the first circular arc pair constitutes a second circular arc pair in which the linear material is wound in a figure eight.
