Delivery shelf system and its control method
A delivery shelf system includes a shelf extending from an exterior to an interior of a building, and a returnable box (RB) stored and slidably supported in the shelf. A first recessed part (FRP) is provided in an indoor-side end part of RB and a second recessed part (SRP) is provided in an outdoor-side end part thereof; a locking mechanism including a projecting part configured to be pressed and inserted into FRP or into SRP is provided at the indoor-side end part of the shelf; the projecting part is inserted into FRP while RB is stored in the shelf, so that RB is locked to the shelf; and when the projecting part is retracted from FRP by releasing the locking and RB is pulled out from the shelf into inside the building, the projecting part is inserted into SRP and the pulled-out RB is thereby stopped.
1. A delivery shelf system comprising:
a shelf extending from an exterior of a building to an interior thereof; and
a returnable box configured to be stored and slidably supported in the shelf, wherein
upon the returnable box being delivered, it can be pushed from outside the building into the shelf, and the returnable box stored in the shelf can be pulled out from the shelf from inside the building, and wherein
a first recessed part is provided in an indoor-side end part of the returnable box and a second recessed part is provided in an outdoor-side end part thereof, the indoor-side end part being an end part of the returnable box that is positioned on an indoor side when the returnable box is stored in the shelf,
a locking mechanism including a projecting part is provided at the indoor-side end part of the shelf, the projecting part being configured to be pressed and inserted into the first recessed part or into the second recessed part,
the projecting part is inserted into the first recessed part while the returnable box is stored in the shelf, so that the returnable box is locked to the shelf, and
when the projecting part is retracted from the first recessed part by releasing the locking and the returnable box is pulled out from the shelf into inside the building, the projecting part is inserted into the second recessed part and the pulled-out returnable box is thereby stopped,
the second recessed part is inclined with respect to an upper surface of the returnable box toward an indoor side.
2. The delivery shelf system according to claim 1 , wherein
the second recessed part becomes larger toward the indoor side, and
when the pulled-out returnable box is pushed back from inside the building into the shelf, the second recessed part passes through the projecting part without unlocking the returnable box.
3. A delivery shelf system comprising:
a shelf extending from an exterior of a building to an interior thereof;
a returnable box configured to be stored and slidably supported in the shelf,
a sensor configured to detect a movement of the returnable box from a storage position of the returnable box in the shelf toward an indoor side, wherein
upon the returnable box being delivered, it can be pushed from outside the building into the shelf, and the returnable box stored in the shelf can be pulled out from the shelf from inside the building, and wherein
a first recessed part is provided in an indoor-side end part of the returnable box and a second recessed part is provided in an outdoor-side end part thereof, the indoor-side end part being an end part of the returnable box that is positioned on an indoor side when the returnable box is stored in the shelf,
a locking mechanism including a projecting part is provided at the indoor-side end part of the shelf, the projecting part being configured to be pressed and inserted into the first recessed part or into the second recessed part,
the projecting part is inserted into the first recessed part while the returnable box is stored in the shelf, so that the returnable box is locked to the shelf,
when the projecting part is retracted from the first recessed part by releasing the locking and the returnable box is pulled out from the shelf into inside the building, the projecting part is inserted into the second recessed part and the pulled-out returnable box is thereby stopped, and
after unlocking the returnable box, when the sensor has detected the movement of the returnable box, a state of the returnable box is changed from an unlocked state to a locked state.
4. The delivery shelf system according to claim 1 , wherein the locking mechanism is a solenoid lock configured to retract the projecting part and thereby unlock the returnable box in an energized state.
5. The delivery shelf system according to claim 1 , wherein a roller is provided at a tip of the projecting part.
6. The delivery shelf system according to claim 1 , wherein
the shelf comprises a housing and a pair of support members extending in a depth direction inside the housing,
the returnable box comprises protrusion parts protruding outward in a width direction and configured to slide on the pair of support members, and
the first and second recessed parts are disposed in one of upper and lower surfaces of the projecting part, and the one of the upper and lower surfaces and the projecting part of the locking mechanism slide on each other.
7. The delivery shelf system according to claim 6 , wherein at both ends of each of the protrusion parts in a sliding direction, one of the upper and lower surfaces thereof is inclined from a horizontal surface so as to get closer to the other of the upper and lower surfaces thereof, and a thickness of each of the protrusion parts is reduced toward both ends of that protrusion part in the sliding direction.
8. A method for controlling a delivery shelf system,
the delivery shelf system comprising:
a shelf extending from an exterior of a building to an interior thereof, and
a returnable box configured to be stored and slidably supported in the shelf, wherein
upon the returnable box being delivered, it can be pushed from outside the building into the shelf, and the returnable box stored in the shelf can be pulled out from the shelf from inside the building, and wherein
a first recessed part is provided in an indoor-side end part of the returnable box and a second recessed part is provided in an outdoor-side end part thereof, the indoor-side end part being an end part of the returnable box that is positioned on an indoor side when the returnable box is stored in the shelf, and the outdoor-side end part being an end part of the returnable box that is positioned on an outdoor side when the returnable box is stored in the shelf,
a locking mechanism including a projecting part is provided at the indoor-side end part of the shelf, the projecting part being configured to be pressed and inserted into the first recessed part or into the second recessed part,
the projecting part is inserted into the first recessed part while the returnable box is stored in the shelf, so that the returnable box is locked to the shelf,
when the projecting part is retracted from the first recessed part by releasing the locking and the returnable box is pulled out from the shelf into inside the building, the projecting part is inserted into the second recessed part and the pulled-out returnable box is thereby stopped, and
the second recessed part is inclined with respect to an upper surface of the returnable box toward an indoor side.
