  However, the structure as shown in FIG. 14 is such that the inner movable deck 150 cannot move below the fixed deck 130 together with the transporter 120, and a parking shelf is disposed below the entry floor. It cannot be used for parking devices such as the system or upper entry system.

  Accordingly, an object of the present invention is to enable the pallet to be transported to a parking shelf below the entrance floor and to hold the movable deck attached to the transporter at the same level as the fixed deck.

  In order to solve the above-mentioned problem, the parking device of the present invention has a first state in which the extending direction of the pallet coincides with the loading / unloading direction and the extending direction of the pallet is the loading / unloading direction on the entry floor. A plurality of parking devices arranged with a turning device for turning between a second state that matches different storage directions and a pallet in the second state arranged above and below the entrance floor or below the entrance floor A transporter that moves up and down along a shelf, and a floor surface of the boarding floor that is beside the pallet in the first state, are spaced apart from each other in the loading / unloading direction, and the transporter and the pallet can pass between them. A pair of fixed decks forming a gap, a movable deck attached to the transporter to move up and down to close the gap, and the gap disposed below at least one of the pair of fixed decks. Comprising of a support position for holding said movable deck to the pair of fixed deck the same level projects downwardly, and a support member for movement between a retracted position retracted below the pair of fixed deck.

Is possible. On the other hand, if the support member is moved to the support position, the movable deck can be held at the same level as the fixed deck. In addition, since the support member is covered with the fixed deck at the retracted position, the support member can be protected from dust and water.

  The support member may include a rotation shaft extending in the storage direction, and may be configured to swing around a central axis of the rotation shaft. According to this configuration, the support member can be moved with a smaller driving force than when the support member moves linearly between the support position and the retracted position.

  The parking apparatus may further include a linear actuator that swings the support member by expansion and contraction. According to this configuration, the support member can be swung with a simple structure.

  The support member may include a receiving portion for receiving the movable deck, which is positioned above the rotating shaft. According to this configuration, the movable deck can be supported in the immediate vicinity of the fixed deck.

  The support member may include a stay that protrudes from the rotating shaft to the opposite side of the receiving portion and contacts the stopper when the support member swings to the support position. According to this configuration, the stopper can receive the rotational force acting on the support member due to the weight of the movable deck.

  For example, the movable deck is one or both of an inner movable deck adjacent to the pallet and an outer movable deck that can move up and down independently with respect to the inner movable deck.

  According to the present invention, the pallet can be transported to the parking shelf below the entrance floor, and the movable deck attached to the transporter can be held at the same level as the fixed deck.

  As described above, in the parking apparatus 1 according to the present embodiment, if the support member 90 is moved to the retracted position, the transporter 13 and the movable decks 35 and 81 are separated from each other by the gap between the front fixed deck 32 and the rear fixed deck 33. Thus, the pallet 20 can be transported to a parking shelf below the entrance floor. On the other hand, if the support member 90 is moved to the support position, the movable decks 35 and 81 can be held at the same level as the front fixed deck 32 and the rear fixed deck 33. Moreover, since the support member 90 is covered with the fixed deck (32 or 33) in the retracted position, the support member 90 can be protected from dust and water.

  In the present embodiment, since the support member 90 swings between the support position and the retracted position, the driving force is smaller than when the support member 90 moves linearly between the support position and the retracted position. The support member 90 can be moved.

  In this embodiment, since the linear actuator 47 is used as means for swinging the support member 90, the support member 90 can be swung with a simple structure.

  In this embodiment, since the rubber plate 95 for receiving the movable decks 35 and 81 is located above the rotary shaft 92, the movable decks 35 and 81 are located in the immediate vicinity of the fixed deck (32 or 33). Can be supported.

  In the present embodiment, the stay 94 abuts against the stopper 51 via the rubber plate 96 when the support member 90 swings to the support position, so that the rotation acting on the support member 90 due to the weight of the movable decks 35 and 81 is performed. The force can be received by the stopper 51.

(Modification)
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

  For example, only one of the inner movable deck 35 and the outer movable deck 81 may be attached to the transporter 13 so as to be movable up and down. In this case, the other of the inner movable deck 35 and the outer movable deck 81 may be attached to the transporter 13 through an elevating mechanism that moves the movable deck up and down, or may be fixed to the transporter 13. However, the inner movable deck 35 and the outer movable deck 81 can both move up and down independently, or one can move up and down, and the other can be moved up and down by a lifting mechanism. It is desirable. Alternatively, a movable deck in which the inner movable deck 35 and the outer movable deck 81 are integrated may be attached to the transporter 13 so as to be movable up and down.

  Further, depending on the support position of the support member 90 and the manner in which the movable deck is supported by the support member 90, the support member 90 can be disposed only below one of the front fixed deck 32 and the rear fixed deck 33.
