Similarly, a pair is formed by the guide rails 7C and 7D disposed at the two right corners in FIG. 8, and a rotation shaft is provided between the bearing devices 9C and 9D disposed near the lower portion of the guide rails 7C and 7D forming the pair. 10B is supported. Two sprockets 11C and 11D are coupled to the rotating shaft 10B.

  On the other hand, a lift drive motor 12 is disposed at an intermediate portion between the guide rails 7A and 7C, and the rotation drive shafts 13A and 13B of the lift drive motor 12 are connected to the rotation shafts 10A and 14B via transmission direction conversion devices 14A and 14B. 10B. The lift driving device is not limited to this configuration, and various other configurations can be employed.

  As shown in FIG. 7, a rotating shaft 15A is rotatably supported on the upper part of the pair of guide rails 7A and 7B, and a sprocket represented by a sprocket 16A at a position corresponding to the lower sprockets 11A and 11B. 16A and 16B are connected. Similarly, on the upper part of the pair of guide rails 7C and 7D, a rotating shaft 15B is rotatably supported, and sprockets 16C and 16D, which are representatively represented by the sprocket 16C, are located at positions corresponding to the lower sprockets 11C and 11D. Are combined.

  Between the sprocket 11A and the sprocket 16A facing each other in the vertical direction, between the sprocket 11B and the sprocket 16B, between the sprocket 11C and the sprocket 16C, and between the sprocket 11D and the sprocket 16D, chains 17A to 17D represented by chains 17A and 17B are respectively represented. It is hung. Further, on the hoistway wall surface side of the guide rails 7A, 7B and the hoistway wall surface side of the guide rails 7C, 7D, which are located at both ends in the longitudinal direction of the elevator platform 8, counterweights 18A for balancing with the elevator platform 8, respectively. , 18B are arranged. The counterweight 16A is connected to the chain 17A, 17B and the counterweight 16A is connected to the left end of the elevator 8 in the longitudinal direction, and the counterweight 16B is connected to the chain 17C, 17D. .

  Accordingly, when the lift driving motor 12 is rotationally driven, the rotational drive shafts 13A and 13B are rotated, and the rotational shafts 10A and 10B and the sprockets 11A to 11D are rotated via the transmission direction conversion devices 14A and 14B.

  As shown in FIG. 7, a tray turning device 19 is mounted on the lifting platform 8, and lifting deck devices 20 </ b> A and 20 </ b> B are configured on both sides of the tray turning device 19.

  FIG. 4 is a front view showing the lift device 3 in more detail.

  Since the lifting deck devices 20A and 20B have a symmetrical configuration, here, the lifting deck 20B on the right side will be mainly described.

  The lifting deck device 20B includes a motor 21 that constitutes a deck driving device supported and fixed to the lifting platform 8 and a flat movable deck that covers the upper portion of the lifting platform 8 so that the driver is positioned under the foot of the parked vehicle. 22, a guide roller 23 rotatably attached to the lower portion of the movable deck 22, a movable member 24 connected to one end of the movable deck 22, and a guide roller that is rotatably attached to the movable member 24 to assist movement. 25, a lever 26 having one end rotatably connected to an intermediate portion of the lower surface of the movable deck 22 and a second end rotatably connected to the lifting platform 8, and a closure holding the movable deck 22 substantially horizontally. It has a lifting deck rail 27 that is fixedly provided on the lifting platform 8 so as to receive the guide roller 23 at a position and hold the state thereof.

  The movable deck 22 is disposed between the tray turning device 19 and the guide rails 7C and 7D, and has a simple rectangular plate-like configuration as shown in FIG. With such a configuration of the pulling deck device 20B, the movable deck 22 is housed in a position that does not interfere with the turning of the tray 5 by the deck driving device such as the motor 21, and the movable deck is rotated by the rotation of the motor 21 in the reverse direction. A storage device is configured that can drive 22 in the reverse direction and return it to a position that forms a substantially series of horizontal surfaces with the tray 5.

  Further, during the operation of the lifting deck devices 20A and 20B that make the movable deck 22 in a closed state in which the movable deck 22 is substantially horizontal or in an open state in which the movable deck 22 is substantially vertical, the flat movable deck 22 is not folded and remains in its shape. Can be driven. Therefore, the movable deck 22 does not need to be divided and can be configured simply. Moreover, since the movable member 24 is configured to move up and down along the deck guide rails 35 and 36 as will be described later, the movable member 24 can operate easily and reliably, and the movable deck 22 is reliably opened from the closed state, Or it can be made to shift from an open state to a closed state reliably.

  In addition, when the movable deck 22 is lifted from a substantially horizontal closed state to a substantially vertical open state with a flat plate shape, the movable deck 22 moves toward the guide rails 7A and 7B and the opposing side of the guide rails 7C and 7D. Is also stored in the upper part of the lifting platform 8, so that it is not necessary to secure a space for folding the deck device in the hoistway 6 as in the prior art, and the hoistway 6 is made smaller and the lifting device 3 is made smaller. be able to.

  The lifting deck devices 20A and 20B arranged on the left and right in the figure operate simultaneously in a symmetrical configuration. However, in FIG. 4, the lifting deck device 20 </ b> A shown on the left side shows a closed state when the movable deck 22 is disposed substantially horizontally, while the lifting deck device 20 </ b> B has the movable deck 22 inclined. Further, the movable deck 22 is in a substantially vertical open state when it is further operated.

  The elevator 8 includes a motor 28 that constitutes a tray driving device used when the tray 5 is moved to the parking floor, a motor 29 that is a turning driving device used when the tray 5 is turned, A power transmission device 30 such as a gear or a chain for transmitting rotation is disposed. The tray turning device 19 disposed at the center of the lifting platform 8 located between the lifting deck devices 20A and 20B transmits the rotation of the motor 29, which is a turning drive device, via the power transmission device 30, and the tray 5 is transferred to a predetermined level. It can turn on the same horizontal plane by an angle.

  5 and 6 are a side view and a plan view showing a specific configuration of the storage device in the pulling deck device 20B described above.

  As shown in FIG. 6, rollers 32C and 32D for guiding the elevator 8 to move up and down along the guide rails 7C and 7D are attached to the frame 31 constituting the elevator 8, respectively. Further, as shown in FIG. 5, the lower end portions of two lifting deck columns 33 and 34 arranged vertically are fixed to the frame 31. The lifting deck columns 33 and 34 are fixed to the lifting platform 8 at positions where they do not interfere with the turning of the tray 5, and the shaft length is shorter than that of the guide rails 7C and 7D.

Deck guide rails 35 and 36 are fixed substantially vertically on the opposite side of the lifting deck columns 33 and 34. On the deck guide rails 35 and 36, the movable member 24 shown in FIG. 4 is arranged so as to be movable up and down. Specifically, a guide roller 25 that guides the movement while rolling along the deck guide rails 35 and 36 is attached to the movable member 24. A motor 37 (showing the same thing as the motor 21 in FIG. 4) constituting the deck driving device of the lifting deck device 20B is attached to the frame 31 positioned below between the lifting deck columns 33 and 34. On the other hand, the upper end portions of the lifting deck columns 33 and 34 are coupled by a support member 38, and a driven sprocket 39 is rotatably attached to the support member 38.

  The driving side sprocket and the driven side sprocket 39 of the motor 37 are opposed to each other in the vertical direction, and both are connected by a chain 40. The pair of movable members 24 is coupled to a coupling member 41, and an intermediate portion of the chain 40 is coupled to the coupling member 41. The coupling member 41 and the movable member 24 are connected to the right side end portion of the movable deck 22 shown in FIG. 4, and the other end of the lever 26 having one end connected to the lower portion of the movable deck 22 is rotatable about the shaft 42. Connected. Therefore, when the other end of the lever 26 is positioned almost directly below the movable member 24 and the movable deck 22 is opened between the two, the movable deck 22 can be made sufficiently thin in the thickness direction.

  When the lifting deck device 20B is changed from a substantially horizontal closed state to a substantially vertical open state, the motor 37 constituting the deck driving device is opened. Then, the rotation of the motor 37 drives the chain 40, and the coupling member 41 and the movable member 24 are pulled upward through the chain 40 in FIG. The movement at this time is smoothly performed by the rolling of the guide roller 25 of the movable member 24 and is reliably guided upward along the deck guide rails 35 and 36. Simultaneously with the upward movement of the movable member 24, the lever 26 shown in FIG. 4 is rotated clockwise about the shaft 42. Therefore, the movable deck 22 is pulled up while rotating counterclockwise around the connecting portion with the lever 26, and is housed in the guide rails 7C and 7D side. It will be thin.

  When the lifting deck device 20B is changed from a substantially vertical open state to a substantially horizontal closed state, the motor 37 constituting the deck driving device is closed. Then, the movable member 24 is now guided downward along the deck guide rails 35 and 36 by the reverse rotation of the motor 37. Therefore, the movable deck 22 is pulled down while rotating clockwise around the connecting portion with the lever 26 and eventually becomes a substantially horizontal closed state, and finally the upper portion of the lifting platform 8 with the width of the movable deck 22. Block.

  As described above, in the lifting deck devices 20A and 20B, the movable deck 22 is composed of a single plate-like member, and the other end of the lever 26 rotatably connected to the middle lower portion of the movable deck 22 is guided rails 7A to 7D. The deck guide rails 35 and 36 are disposed on the lift base 8 which is rotatably supported by the lift base 8 on the side and is located in the vicinity of the guide rails 7 </ b> A to 7 </ b> D, and the deck guide rails 35 and 36 for the movable deck 22. The movable member 24 is connected to the end portion located on the side, and the movable member 24 is moved upward along the guide rails 35 and 36 for the deck, so that the movable deck 22 is opened from a substantially horizontal closed state to a substantially vertical opening. It is configured to be pulled up to the state and housed on the deck guide rails 35 and 36 side, respectively.

  Therefore, the operation of opening the movable deck 22 is only to pull up the movable member 24 along the guide rails 35 and 36 for the deck, and it is not necessary to perform the folding operation. Therefore, the operation between the closed state and the open state is performed. It can be carried out smoothly and stably. In addition, since the movable deck can be stored on the lifting platform side, it is not necessary to secure a space for folding the movable deck in the lift hoistway 6 as in the prior art, and the lift hoistway 6 can be made smaller and the lift device 3 can be made small.

  Further, the lifting deck devices 20A and 20B are provided with a lever 26 having one end rotatably connected to an intermediate lower portion of a single plate-shaped movable deck 22, and the other end of the lever 26 is positioned directly or near the elevator base 8. The other end of the lever 26 is positioned so as to be positioned almost directly below the movable member 24 in the open state.

  According to such lifting deck devices 20A and 20B, in the almost vertical open state, the other end of the lever 26, which is the center of rotation, and the movable member 24 face each other in a vertical relationship, and the weight of the movable deck 22 can be easily increased. Will be able to hold. On the other hand, in the substantially horizontal closed state, the end of the movable deck 22 on the tray turning device 19 side can be supported by the lever 26, and therefore can be easily received by the guide rail 27 having a shorter axial length than the conventional one. Further, the lifting deck devices 20A and 20B are arranged not only on the movable deck 22 but also on the lifting platform 8 side including the motor 21 which is a deck driving device. For this reason, the adjustment work of the positional relationship or operation relationship of each part becomes easy. Further, it is not necessary to move the motor, which is a deck driving device, together with the opening or closing operation of the movable deck 22 as in the prior art, and the wiring for the motor is not damaged. In addition, since the other end of the lever 26 is positioned almost directly below the movable member 24 in the opened state of the lifting deck devices 20A and 20B, the single plate-shaped movable deck 22 is substantially vertical in the opened state, and the lifting deck device. The width direction of 20A, 20B becomes thin.

  In this way, the lifting deck devices 20A and 20B in the open state are thin, the configuration in the vicinity thereof is simplified, and the lifting and lowering unit 6 is not enlarged by the lifting deck devices 20A and 20B.

  Next, a series of operations of each part when moving the parked vehicle 4 to the parking floor 2 will be described.

  When the parked vehicle 4 is stored, the lift device receives a store operation command, and firstly places the empty tray 5 on the tray turning device 17 of the lift 8 and moves the lift 8 to the loading / unloading floor 1. At this time, the direction of the tray 5 remains the same as the direction of the parked vehicle stored in the parking floor 2 in the longitudinal direction of the rectangle. Further, the lifting deck devices 20A and 20B are in a substantially vertical open state, and are stored in the deck guide rails 35 and 36 side on the lifting platform 8, respectively.

  After the elevator 8 arrives at the entry / exit floor 1 or prior to it, the lift device 3 enters the entry / exit floor 1 so that it does not interfere with nearby structures when the tray 5 turns. The elevator 8 is moved to a turning level slightly above the turning level. Thereafter, the lift device 3 adjusts the direction of the tray 5 to the approach direction of the parked vehicle 4 about to enter as shown in FIG. This tray direction changing operation is performed by warehousing the motor 29 which is a turning drive device. The rotation of the motor 29 turns the tray turning device 19 by the power transmission device 30 and turns the tray 5 mounted on the upper portion of the tray 29 so that the direction of the tray 5 enters as shown in FIG. To match.

  Next, the lift device 3 shifts the movable deck 22 of the lifting deck devices 20A and 20B to a substantially horizontal closed state as a deck closing operation. In this deck closing operation, the motor 21 which is a deck driving device is closed and the movable member 24 is driven downward along the guide rails 35 and 36 for the deck, and the connecting portion at the lower end of the lever 26 is centered. Rotate to do. As the lever 26 rotates, the movable deck 22 shifts from a substantially vertical state to a substantially horizontal state, and the guide roller 23 is positioned and held on the guide rail 27. Thus, the lifting deck devices 20A and 20B are in a closed state.

  Next, the lift device 3 moves the elevator 8 downward by a predetermined distance to hold the tray 5 at the boarding level. In this state, the empty tray 5 has a direction different from the direction of the parked vehicle stored in the parking floor 2 by 90 degrees as shown in FIGS.

  After the series of operations by the tray turning device 17 is completed, the entry of the parked vehicle 4 is permitted. Therefore, the driver advances the parked vehicle 4 straight in the approach direction, rides on the tray 5, and stops at a predetermined position. At this time, the longitudinal direction of the tray 5 is the entry direction of the parked vehicle 4, and the parked vehicle 4 can be easily placed on the tray 5. Thereafter, the driver gets off the parked vehicle 4, but at that time, both sides in the longitudinal direction of the tray 5, that is, the feet on the side where the driver gets off the parked vehicle 4 are already closed by the movable decks 22 of the pull-up deck devices 20A and 20B. In addition, since the movable deck 22 has a flat plate shape, the driver can walk on the movable deck 22 and move safely.

  The protective plate is positioned so that the driver who gets off the parked vehicle 4 does not touch the mechanism located between the guide rails 7A and 7B and between the guide rails 7C and 7D and does not interfere with the operation of the lifting deck devices 20A and 20B. Etc. may be arranged.

  After the operation so far is completed, the lift device 3 raises the lifting platform 8 again to a turning level that does not interfere with other structures during turning, performs the deck opening operation, and then performs the tray turning operation. Do. The above-described deck opening operation is performed by driving the motor 21 which is a deck driving device in the pulling deck devices 20A and 20B to open and driving the movable member 24 upward along the deck guide rails 35 and 36. As the movable member 24 moves up, the movable deck 22 is moved while rotating around the connecting portion at the lower end of the lever 26.

The deck guide rails 35 and 36 are disposed on the lifting platform 8 located near the deck, and the movable member 24 is connected to the end of the movable deck 22 on the deck guide rails 35 and 36 side. It is moved along the deck guide rails 35 and 36 so that the whole is pulled up from a substantially horizontal closed state to a substantially vertical open state and stored in the deck guide rails 35 and 36 side, respectively. .

  According to such a mechanical parking facility, the operation of opening the movable deck 22 only needs to pull up the movable member 24 along the guide rails 35 and 36 for the deck, and it is not necessary to perform a folding operation. And the open state can be performed smoothly and stably. Further, it is not necessary to secure a space for folding the movable deck in the lift hoistway 6 as in the prior art, and the lift hoistway 6 can be made smaller and the lift device 3 can be made smaller.

  The mechanical parking facility according to the present invention is provided with a lever 26 having one end rotatably connected to an intermediate lower portion of a single plate-like movable deck 22, and the other end of the lever 26 is directly or in the vicinity of the lifting platform 8. The other end of the lever 26 is positioned so as to be substantially directly below the movable member 24 in the open state.

  According to such a mechanical parking facility, in the almost vertical open state, the other end of the lever 26 that is the center at the time of rotation and the movable member 24 face each other in a vertical relationship, and thereby the weight of the movable deck 22 is increased. It can be easily held. On the other hand, in the substantially horizontal closed state, the end of the movable deck 22 on the tray turning device 19 side can be easily received by the guide rail 27 having a short axial length. Further, since not only the movable deck 22 but also the deck drive devices of the lifting deck devices 20A and 20B are arranged on the lifting platform 8 side, the adjustment work of the positional relationship and operation relationship of each part is simplified. Further, it is no longer necessary to move the motor, which is a deck driving device, together with the opening or closing operation of the movable deck 22 as in the prior art, and the wiring for the motor is not damaged. In addition, since the other end of the lever 26 is positioned almost directly below the movable member 24 in the opened state of the lifting deck devices 20A and 20B, the single plate-shaped movable deck 22 is substantially vertical in the opened state, and the lifting deck device. The width direction of 20A, 20B becomes thin. In this way, the configuration of the lifting deck devices 20A and 20B and the vicinity thereof is simplified.

  Further, the mechanical parking facility of the present invention is configured to move the parked vehicle 4 entering from the entry / exit floor 1 to the upper parking floor 2 by the lift device 3, and the lifting deck device 20 </ b> A having the movable deck 22 described above. By adopting 20B, it is possible to easily and reliably protect the feet when the driver moves while simplifying the configuration of the floor portion of the loading / unloading floor.

  In the embodiment of the present invention, the movable deck 22 is supported and guided by the lever 26. However, the lever 26 is omitted, and the roller guide for guiding the guide roller 23 provided at the tip of the movable deck 22 is a deck rail. 27 may extend so as to draw a curve so as to be higher toward the guide rails 7A and 7C.
