Abstract

A rack includes: a casing; M pairs of supports that are provided inside the casing so as to extend in a depth direction and arrayed at regular intervals in a predetermined direction; and a lock mechanism. The rack can house all returnable containers of one or more prespecified sizes along the respective pairs of supports. The M pairs of supports are arrayed in N rows in an orthogonal direction orthogonal to the predetermined direction. The lock mechanism is configured such that moving first and second shafts that are provided for the respective rows and for the respective tiers, respectively, so as to be movable in the predetermined direction can switch between engagement and disengagement between branches of the first and second shafts and first and second holes, respectively, of the returnable containers.

First claim

What is claimed is:

1. A delivery rack comprising:
a casing;
M pairs of supports, with M being an integer not less than three, that are provided inside the casing so as to extend in a depth direction and arrayed in M tiers at regular intervals in a predetermined direction that is one of an up-down direction and a left-right direction; and
a lock mechanism that locks returnable containers housed while being supported so as to be slidable along the respective M pairs of supports,
the delivery rack being able to house all the returnable containers of one or more prespecified sizes, wherein:
the M pairs of supports are arrayed in N rows, with N being an integer not less than two, in an orthogonal direction orthogonal to the predetermined direction of the casing, and the delivery rack is able to house a maximum of (M×N) returnable containers;
the lock mechanism includes:
N first shafts that are provided for the respective rows so as to be movable in the predetermined direction, and each have a stem that is provided so as to extend across all the M pairs of supports arrayed in the predetermined direction and M branches that branch off from the stem so as to correspond to the respective M pairs of supports; and
M second shafts that are provided for the respective tiers so as to be movable in the predetermined direction, and each have a stem that is provided so as to extend across all the N rows of supports arrayed in the orthogonal direction of the casing and N branches that branch off from the stem so as to correspond to the respective N rows of supports;
the returnable containers are each provided with a first hole that engages with the branch of the first shaft and a second hole that engages with the branch of the second shaft; and
moving the first shafts in the predetermined direction enables switching between engagement and disengagement between the branches of the first shafts and the first holes, and moving the second shafts in the predetermined direction enables switching between engagement and disengagement between the branches of the second shafts and the second holes.

2. The delivery rack according to claim 1 , wherein:
protrusions that protrude from the returnable container toward outer sides in the orthogonal direction slide over the supports; and
the first hole and the second hole are provided in the protrusions.

3. The delivery rack according to claim 1 , wherein the lock mechanism has driving sources that each separately and electrically drive one among the N first shafts and the M second shafts.

4. A delivery vehicle comprising a rack, wherein:
the rack has:
a casing;
M pairs of supports, with M being an integer not less than three, that are provided inside the casing so as to extend in a depth direction and arrayed in M tiers at regular intervals in a predetermined direction that is one of an up-down direction and a left-right direction; and
a lock mechanism that locks returnable containers housed while being supported so as to be slidable along the respective M pairs of supports;

the rack is able to house all the returnable containers of one or more prespecified sizes;
the M pairs of supports are arrayed in N rows, with N being an integer not less than two, in an orthogonal direction orthogonal to the predetermined direction of the casing, and the rack is able to house a maximum of (M×N) returnable containers;
the lock mechanism includes:
N first shafts that are provided for the respective rows so as to be movable in the predetermined direction, and each have a stem that is provided so as to extend across all the M pairs of supports arrayed in the predetermined direction and M branches that branch off from the stem so as to correspond to the respective M pairs of supports; and
M second shafts that are provided for the respective tiers so as to be movable in the predetermined direction, and each have a stem that is provided so as to extend across all the N rows of supports arrayed in the orthogonal direction of the casing and N branches that branch off from the stem so as to correspond to the respective N rows of supports;

the returnable containers are each provided with a first hole that engages with the branch of the first shaft and a second hole that engages with the branch of the second shaft; and
moving the first shafts in the predetermined direction enables switching between engagement and disengagement between the branches of the first shafts and the first holes, and moving the second shafts in the predetermined direction enables switching between engagement and disengagement between the branches of the second shafts and the second holes.

5. The delivery vehicle according to claim 4 , wherein:
protrusions that protrude from the returnable container toward outer sides in the orthogonal direction slide over the supports; and
the first hole and the second hole are provided in the protrusions.

6. The delivery vehicle according to claim 4 , wherein the lock mechanism has driving sources that each separately and electrically drive one among the N first shafts and the M second shafts.

7. The delivery vehicle according to claim 4 , wherein the delivery vehicle is an autonomous vehicle.
