Further, when the movable guide rails 20A and 20B are rotated 90 degrees and face the width direction, other fixed guide rails 23A and 23B are placed on the width direction straight lines 22A and 22B that match the movable guide rails 20A and 20B. , The fixed guide rails 24A and 24B are fixed corresponding to each other.

Therefore, when the movable guide rails 20A and 20B are oriented in the longitudinal direction as shown in the drawing, the fixed guide rails 19A to 19C and the movable guide rails 20A and 20B are located on the straight line 19 in the longitudinal direction. On the other hand, when the movable guide rails 20A and 20B are oriented in the width direction, the fixed guide rails 23A and 23B and the movable guide rail 20A are located on the width direction straight line 22A, and the fixed guide rails 24A and 24B and the movable guide rail 20B are located. Is located on the width direction straight line 22B.

FIG. 4 is a plan view showing a floor-side tray drive device 16 configured on the floor side of each of the storage spaces described above.

The floor-side tray drive device 16 is configured on a base 25 fixed to the floor surface of each storage space. A first drive device 27 rotatably provided by a rotating shaft 26 provided at a position substantially opposite to the central shaft 21A shown in FIG. 3 and a rotation provided at a position substantially opposed to the central shaft 21B shown in FIG. A second drive device 29 rotatably provided by a shaft 28, and a switching drive device 30 located between the first drive device 27 and the second drive device 29 to switch the rotation angles of the rotation shafts 26 and 28. have.

The switching drive device 30 has a lever 33 that is rotated by a motor 32 about a rotation shaft 31, and a link 34 connected to one end of the lever 33 is attached to a rotation shaft 26 of the first drive device 27. It is connected to a fixed arm 35. The link 36 connected to the other end of the lever 33 is connected to an arm 37 fixed to the rotating shaft 28 of the second drive device 29.

The first drive device 27 sandwiches the motor 38, the feed roller 39 which is a friction roller rotationally driven by the motor 38, and the movable guide rail 20A located on both sides of the rotary shaft 26. Two sets of sandwiching rollers 40 are provided so as to face each other. Further, the second drive device 29 also has the same configuration, and sandwiches the motor 41, the feed roller 42 which is a friction roller rotationally driven by the motor 41, and the movable guide rail 20B located on both sides of the rotary shaft 28. Two sets of sandwiching rollers 43 are provided so as to face each other.

When the motors 38 and 41 are rotationally driven in the illustrated state, the feed rollers 39 and 42 also rotate. The feed rollers 39 and 42 are pressed against the fixed guide rails 19A, 19B, 19C and the like shown in FIG. 3 in the tray-side driven device 13 of the tray 3 arranged in the same storage space, and are longitudinally driven by the rotational force. The tray 3 is moved, for example, in the upward direction shown in the drawing along the straight line 19 in the direction. On the other hand, when the motors 38 and 42 are rotationally driven in the opposite directions, the feed rollers 39 and 42 are rotated in the opposite directions and the tray 3 is moved downward in the drawing along the longitudinal straight line 19 shown in FIG. It will be.

However, when the lever 33 is rotationally driven by the motor 32 of the switching drive device 30 in the counterclockwise direction by a predetermined angle, the first drive device 27 connected via the link 34 is 90 degrees counterclockwise around the rotation axis 26. The second drive device 29 connected via the link 36 is rotated by 90 degrees counterclockwise with respect to the rotation shaft 28. At this time, due to the above-mentioned rotation of the first drive device 27 and the second drive device 29, the movable guide rails 20A and 20B of FIG. 3 sandwiched between the sandwiching rollers 40 and 43 are also rotated by 90 degrees.

In this state, when the feed rollers 39 and 42 are rotated by the motors 38 and 41, the tray 3 shown in FIG. 3 is moved along the width straight lines 22A and 22B, for example, to the left in the drawing. .. On the other hand, when the feed rollers 39 and 42 are rotated in the opposite directions by the motors 38 and 41, the tray 3 shown in FIG. 4 is moved to the right in the drawing along the width straight lines 22A and 22B. Will be.

When such a floor-side tray drive device 16 is configured on the floor side for each storage space, and each tray-side driven device 13 is configured for each tray 3, by selecting a motor that is rotationally driven by a control device (not shown), It is possible to move the predetermined tray 3 to the predetermined storage space. That is, the motors 32, 38, 41 in the floor-side tray drive device 16 provided on the lower floor of the predetermined tray 3 are controlled from the control device while utilizing at least one empty space existing in the storage space. As a result, the predetermined tray 3 is moved to the adjacent empty space. The same applies thereafter, and the predetermined trays 3 are sequentially moved by controlling the motors 32, 38, 41 in the floor side tray drive device 16 newly corresponding to the moved position from the control device while utilizing the new empty space. It can be moved and thus finally moved to a predetermined storage space on its own.

By the way, when the tray 3 is stopped in a predetermined storage space, each motor is stopped and controlled by a control device (not shown), but it has been found that the stop position of the tray 3 varies. In particular, it occurs when the tray 3 in which the parked vehicle is mounted is laterally moved along the floor side width direction guide rail 15B shown in FIG. 4 and stopped at a predetermined stop position. It was found that this was caused by the weight difference between the front side and the back side of the parked vehicle mounted on the tray 3. Next, this solution will be described.

FIG. 5 is an enlarged side view showing a main part in the vicinity of the stop position of the tray 3.

The floor-side width direction guide rail 15B shown in FIG. 2 has a motor 32 in the floor-side tray drive device 16 at a predetermined stop position on the tray 3 and at a position corresponding to the wheels 18A to 18D provided on the tray 3. A stopping force increasing unit 43 that works in cooperation with the stopping control by, 38, 41 is provided. When the stop control by the motors 32, 38, 41 is not performed at the same position, the stopping force increasing unit 43 passes the wheels 18A to 18D without stopping at the same position, but the motors 32, 38, at the same position. When the stop control by 41 is performed, it acts to stop the wheels 18A to 18D at the same position. Since each stopping force increasing portion 43 provided corresponding to each of the wheels 18A to 18D has substantially the same configuration, here, only the stopping force increasing portion 43 corresponding to the wheel 18A and the floor side width direction guide rail 15B is provided. Shown.

The stopping force increasing portion 43 is formed by directly forming a groove in the same portion of the floor side width direction guide rail 15B, or by providing a grooved part in the same portion of the floor side width direction guide rail 15B with increased friction compared to other positions. It can be attached or formed by forming tapered surfaces 44A and 44B on the rollers 44 arranged in the same portion.

When the tray 3 shown in FIG. 3 is moving along the floor side width direction guide rail 15B, each motor is stopped by a control device (not shown) so that the tray 3 is stopped at a predetermined position in a predetermined storage space. 38 and 41 are stopped and controlled. At this time, when the tray 3 reaches a predetermined stop position in a predetermined storage space, the wheel 18A at that time reaches the stop force increasing portion 43. In this stopping force increasing unit 43, in order to increase the braking force with respect to the wheel 18A, the tray 3 is stopped accurately at a predetermined position.

The phenomenon that the stop position of the tray 3 varies slightly is similar to the phenomenon that the tray 3 with the parked vehicle mounted is moved to the vertical direction in FIGS. 3 and 4 and then stopped, although the degree is small. Since the phenomenon may occur, the stopping force increasing portion 43 can be similarly provided on the floor side longitudinal guide rail 15A. Also in this case, the position where the stopping force increasing portion 43 is provided is a position corresponding to the wheels 17A to 17D when the tray 3 is stopped at a predetermined stop position on the floor-side longitudinal guide rail 15A.

In the mechanical parking device configured to perform the above, the floor side tray is driven at the stop position of the tray 3 on the floor side width direction guide rail 15B and at the position corresponding to the wheels 18A to 18D provided on the tray 3. It is characterized in that a stop force increasing unit 43 that works in cooperation with the motor stop control in the device 16 to stop is provided.

According to such a configuration, when the tray 3 in which the parked vehicle is mounted is laterally moved along the floor side width direction guide rail 15B and stopped at a predetermined stop position, the tray 3 is placed on the tray 3. It is possible to suppress the phenomenon that the stop position varies due to the weight difference between the front side and the back side of the mounted parked vehicle, and to accurately stop the tray 3 at a predetermined position in the storage space. Moreover, since the stopping force increasing unit 43 works in cooperation with the motor stop control to stop the tray 3, when the tray 3 only passes through the predetermined storage space, the passage is not blocked.

Further, in addition to the above-described configuration, the present invention provides a floor-side tray drive device at a stop position of the tray 3 on the floor-side longitudinal guide rail 15A and at a position corresponding to the wheels 17A to 17D provided on the tray 3. It is characterized in that a stop force increasing unit 43 that works in cooperation with the motor stop control in 16 to stop is provided.

According to such a configuration, when the tray 3 in which the parked vehicle is mounted is moved in the vertical direction along the floor-side longitudinal guide rail 15A and stopped at a predetermined stop position, due to a similar factor. It is possible to suppress the variation of the stop position and accurately stop the tray 3 at a predetermined position in the storage space. Moreover, since the stopping force increasing unit 43 works in cooperation with the motor stop control to stop the tray 3, when the tray 3 only passes through the predetermined storage space, the passage is not blocked.
