Abstract

A rack includes a casing and a plurality of pairs of supports that is provided inside the casing so as to extend in a depth direction and arrayed at regular intervals in an up-down direction. The rack can house all storage boxes of two or more prespecified sizes while supporting the storage boxes so as to be slidable along the respective pairs of supports. Sensors that detect objects are provided one between each two pairs of supports that are adjacent to each other in the up-down direction among the pairs of supports. When storage boxes of a smallest size are housed in the rack so as to be closest to one another in the up-down direction, the sensors are located in clearances between the storage boxes of the smallest size in the up-down direction.

First claim

What is claimed is:

1. A rack comprising:
a casing;
a plurality of pairs of supports that is provided inside the casing so as to extend in a depth direction and arrayed at regular intervals in an up-down direction,
the rack being able to house storage boxes of two or more prespecified sizes while supporting the storage boxes so as to be slidable along the respective pairs of supports;
for each of the pairs of supports, a lock mechanism that locks the storage box when the storage box is housed; and
protrusions that protrude from the storage box toward outer sides in a width direction slide over each of the pairs of supports, wherein:
sensors that detect objects are provided one between each two pairs of supports that are adjacent to each other in the up-down direction among the pairs of supports;
when storage boxes of a smallest size are housed in the rack so as to be closest to one another in the up-down direction, the sensors are located in clearances between the storage boxes of the smallest size in the up-down direction;
each of the lock mechanisms detects that the storage box has been locked and is provided so as to face corresponding one of the pairs of supports and slide on the protrusion of the storage box; and
a sliding surface of each of the pairs of supports that slides on the protrusion and a sliding surface of each of the lock mechanisms that slides on the protrusion are both provided with rollers.

2. The rack according to claim 1 , wherein:
identification information is attached to each of the storage boxes; and
the rack further comprises, for each of the pairs of supports, a reader that reads the identification information.

3. A delivery vehicle comprising a rack that has:
a casing;
a plurality of pairs of supports that is provided inside the casing so as to extend in a depth direction and arrayed at regular intervals in an up-down direction,
the rack being able to house returnable containers of two or more prespecified sizes while supporting the returnable containers so as to be slidable along the respective pairs of supports;
for each of the pairs of supports, a lock mechanism that locks the returnable container when the returnable container is housed; and
a protrusion that protrudes from the returnable container toward an outer side in a width direction slides over each of the pairs of supports, wherein:
the rack has sensors that detect objects and are provided one between each two pairs of supports that are adjacent to each other in the up-down direction among the pairs of supports;
when returnable containers of a smallest size are housed in the rack so as to be closest to one another in the up-down direction, the sensors are located in clearances between the returnable containers of the smallest size in the up-down direction;
each of the lock mechanisms detects that the returnable container has been locked and is provided so as to face corresponding one of the pairs of supports and slide on the protrusion of the returnable container; and
a sliding surface of each of the pairs of supports that slides on the protrusion and a sliding surface of each of the lock mechanisms that slides on the protrusion are both provided with rollers.

4. The delivery vehicle according to claim 3 , wherein:
identification information is attached to each of the returnable containers; and
the delivery vehicle further comprises, for each of the pairs of supports, a reader that reads the identification information.

5. The delivery vehicle according to claim 3 , wherein the delivery vehicle is an autonomous vehicle.
