Abstract

In a block ( 10 ) for a cable of the present disclosure, the block has a shape of a rectangular cuboid in which an upper surface ( 11 ) and a bottom surface have square shapes, the block has plural bending through holes ( 21 ) between one side surface of the rectangular cuboid and a side surface ( 12 ) neighboring the one side surface, arrangement of open ends ( 22 ) of the plural through holes in the one side surface of the rectangular cuboid is in a lattice manner, the arrangement of the open ends is in line symmetry with respect to a middle line ( 31 ) between an upper side and a bottom side of the one side surface and with respect to a middle line ( 32 ) between a lateral side and a lateral side of the one side surface, and arrangement of open ends ( 22 ) of the plural through holes in the side surface neighboring the one side surface of the rectangular cuboid is the same as the arrangement of the open ends ( 22 ) of the plural through holes in the one side surface of the rectangular cuboid.

First claim

The invention claimed is:

1. A block for a cable, wherein
the block has a shape of a rectangular cuboid in which an upper surface and a bottom surface have square shapes,
the block has plural bending through holes between one side surface of the rectangular cuboid and a side surface neighboring the one side surface,
arrangement of open ends of the plural through holes in the one side surface of the rectangular cuboid is in a lattice manner,
the arrangement of the open ends is in line symmetry with respect to a middle line between an upper side and a bottom side of the one side surface and with respect to a middle line between a lateral side and a lateral side of the one side surface, and
arrangement of open ends of the plural through holes in the side surface neighboring the one side surface of the rectangular cuboid is the same as the arrangement of the open ends of the plural through holes in the one side surface of the rectangular cuboid.

2. A block group for a cable, wherein the plural blocks for a cable according to claim 1 , which have bottom surfaces with the same size and the same height and between side surfaces of which arrangements of open ends of plural through holes correspond to each other, are coupled together via side surfaces.

3. A wiring method, wherein
the plural block groups for a cable according to claim 2 are arranged in a lattice manner, and a cable is caused to pass through the through holes.

4. A wiring method, wherein
the plural block groups for a cable according to claim 2 whose heights are lower than a double floor are arranged under the double floor in a lattice manner, and a cable is caused to pass through the through holes.

5. A configuration method of a block group for a cable, wherein the plural blocks for a cable according to claim 1 , which have bottom surfaces with the same size and the same height and between side surfaces of which arrangements of open ends of plural through holes correspond to each other, are coupled together via side surfaces, and a cable wiring route is secured.

6. A block for a cable, wherein
the block has a shape of a rectangular cuboid in which an upper surface and a bottom surface have square shapes,
the block has plural through holes extending straight between one side surface of the rectangular cuboid and a side surface opposed to the one side surface,
arrangement of open ends of the plural through holes in the one side surface of the rectangular cuboid is in a lattice manner and corresponds, of a first group and a second group, to the first group wherein the first group and the second group are defined so that alignment in line symmetry with respect to a middle line between an upper side and a bottom side of the one side surface and with respect to a middle line between a lateral side and a lateral side of the one side surface is divided into the first group and the second group, the open ends at the same height from the bottom surface belonging to the same group, the open ends of the first group and the open ends of the second group being in rotational symmetry with respect to a center of the one side surface, and
arrangement of open ends of the plural through holes in the side surface opposed to the one side surface of the rectangular cuboid is the same as the arrangement of the open ends of the plural through holes in the one side surface of the rectangular cuboid.

7. A block for a cable, wherein
the block has a shape of a rectangular cuboid in which an upper surface and a bottom surface have square shapes,
the block has plural through holes extending straight between one side surface of the rectangular cuboid and a side surface opposed to the one side surface,
the block has plural through holes extending straight between side surfaces neighboring the one side surface of the rectangular cuboid, arrangement of open ends of the plural through holes in the one side surface of the rectangular cuboid is in a lattice manner and corresponds, of a first group and a second group, to the first group wherein the first group and the second group are defined so that alignment in line symmetry with respect to a middle line between an upper side and a bottom side of the one side surface and with respect to a middle line between a lateral side and a lateral side of the one side surface is divided into the first group and the second group, the open ends at the same height from the bottom surface belonging to the same group, the open ends of the first group and the open ends of the second group being in rotational symmetry with respect to a center of the one side surface, and
arrangement of open ends of the plural through holes in the side surface neighboring the one side surface of the rectangular cuboid corresponds to the second group.
