Place and fix the bicycle in a horizontal position, move it up and down to a predetermined position, push the bicycle together with the stand from the lifting frame into the storage area, and when taking the bicycle out of the garage, move the bicycle together with the stand from the storage area to the lifting frame. Retractable devices are known.

[Problem that the invention seeks to solve]

However, in the case of the conventional bicycle loading/unloading device, the bicycle is placed in a horizontal state on a pedestal on a lifting frame and the lifting frame is raised and lowered, so the length of the lifting frame in the longitudinal direction of the bicycle becomes long. If you need a large lifting space, and if two or more bicycles are to be parked in succession, once the first bicycle has been parked, move the lift frame to a location with an empty stand, and then lift and lower the empty stand. After pulling it onto the frame, the elevating frame must be moved up and down to the entrance.If two or more bicycles are to be taken out in succession, the elevating frame must be moved after the first bicycle has been taken out. , move the empty stand on the lifting frame back to its original storage location, then move the lifting frame to the storage area where the second bicycle to be taken out is located, and place the second bicycle together with the stand on the moving frame. must be drawn into. Therefore, there is a problem that the loading/unloading operation is complicated and the loading/unloading cycle time becomes long.

5 and the wheel support roller 56 into an inclined state, and when the pushing arm 5 is pulled to a predetermined position shown in FIG. 12, the operation of the pushing drive device 4 is automatically stopped. In this state, only the rear wheel 66 is supported by the wheel support roller 56, or the front wheel 41 and the rear wheel 66 are supported by the wheel support roller 56.
both are supported by wheel support rollers 56.

(6) Next, the lifting drive device 27 is operated, and the lifting frame 2 carrying the bicycle 40 is moved down to the storage floor, and the swing drive device 21 is operated as necessary to move the post 14,
The guide rail 1 and the elevating frame 2 are rotated, and the elevating frame 2 on which the bicycle 40 to be stored is mounted is arranged so as to face the expected storage location in the bicycle storage stand 11. Note that either the lowering or the turning of the elevating frame 2 may be performed first, or they may be performed simultaneously.

(7) Next, the pushing drive device 4 is operated in the pushing direction, and the pushing arm 5 is rotated in the pushing direction, so that the bicycle 40 is pushed into the storage wheel guide member 57 at the planned storage location. At the same time, the bicycle 40 is held between a pair of synthetic resin retaining plates 60 to prevent it from tilting, and the front wheel 41 is held between a pair of front wheel positioning rollers 47 and 4.
8 and is held so as not to move in the front-back direction.

(8) Next, after the wheel clamp device 6 is released, the pushing arm 5 is rotated to the retracted position,
Subsequently, the elevating frame 2 is moved upward to the loading/unloading position (bicycle delivery position) shown in FIG.

Next, the sequence of operations when taking out a bicycle stored in the device of the above embodiment will be explained.

(1) First, insert your commuter pass card or magnetic ticket into the entry/exit calling device 65 and make payment.

(2) When the payment process is completed, the warehouse entry/exit calling device 65
In response to a control command from the elevator, the elevating frame 2 is moved downward and rotated to a position facing a predetermined storage location.

(3) Next, the pushing arm 5 is rotated in the pushing direction, and after the front wheel 41 is gripped by the wheel clamp device 6 as described above, the pushing arm 5 is rotated in the retracting direction, and the front wheel 41 is gripped by the wheel clamp device 6 as described above. The bicycle 40 is pulled into the wheel guide member 55 and the wheel support roller 56 portion of the lifting frame 2 by the lifting arm 5 via the wheel clamp device 6, and becomes inclined. After the bicycle 40 is pulled to a predetermined position, the bicycle 40 is The elevating frame 2 on which the storage device 40 is mounted is moved upwardly and rotated as necessary, and is moved to the loading/unloading position shown in FIG. 2.

(4) The lifting support member 51 and the tilting prevention member 5 in the bicycle tilting prevention device 54 at the position where it should be taken out of the garage.
2 and open the door 49. These operations may be performed immediately after (2) above.

(5) Next, the pushing arm 5 is rotated in the pushing direction, and the bicycle 40 is pushed out from the wheel guide member 55 and the wheel support roller 56 onto the wheel guide member 46 for the entrance and exit, and then tilted. The prevention member 52 is moved downward, and the lower groove-shaped portion of the tilt prevention member 52 is fitted into the upper part of the front wheel 41, thereby preventing the bicycle 40 from tilting.

(6) Next, after the wheel clamp device 6 is released, the pushing arm 5 is rotated in the retracting direction,
Next, when the bicycle 40 is taken out, the door 49 is automatically closed.

In the case of the above embodiment, the annular bicycle storage stand 1
Since the elevating frame 2 is rotated via the guide rail 1 by the post 14 disposed at the center of the frame 1, there is no need to rotate the bicycle storage stand 11, which is extremely heavy, and therefore the power cost can be reduced. Moreover, the mechanical equipment can be simplified and the cost of the equipment can be lowered.

Although the above embodiment is an example in which the bicycle parking lot building 12 is installed underground, the present invention can also be implemented when the bicycle parking lot building 12 is installed above ground. In this case, the elevating frame 2 is moved upward from the loading/unloading position on the ground.

When carrying out this invention, the clamp arms 38 and 39 may be configured to be rotated by a clamp opening/closing device 37 consisting of a fluid pressure cylinder, as shown in FIG. 16, or as shown in FIG. 17. , a groove-shaped wheel guide support member 6 that supports only the rear wheel 66 on the lower frame member 24 of the elevating frame 2;
7 may be fixed. Furthermore, instead of the computer-based automatic entry/exit control system that uses commuter cards and magnetic tickets, the store manager records empty storage locations, stores bicycles there under manual control, and writes the storage locations to users. Alternatively, a system may be adopted in which the user presents the ticket to the store clerk, and when leaving the store, the user shows the ticket to the store manager, and the store manager manually instructs the location recorded on the ticket and leaves the store.

An arm may be fixed to the upper end of the post 14, and the arm may be connected to the roof frame 17 by a hydraulic cylinder, and the post 14 may be pivoted by the hydraulic cylinder. As the wheel support provided on the lower side, any structure other than that shown in the drawings may be adopted.

As a means for raising and lowering the elevating frame 2, for example, a pinion rotated by an elevating drive device is attached to the elevating frame 2, and the pinion is engaged with a vertical rack fixed to the guide rail 1, and the lifting frame 2 is raised and lowered by rotation of the pinion. A means for raising and lowering the frame may also be employed.

〔Effect of the invention〕

According to this invention, by pulling and rotating the pushing arm 5 while gripping one wheel of the bicycle 40 with the wheel clamp device 6 at the tip of the pushing arm 5, the bicycle 40 is raised and lowered diagonally. It can be mounted on the frame 2, so that the space occupied by the lifting frame 2 for lifting and lowering can be narrowed.Furthermore, when one wheel of the bicycle 40 is gripped by the wheel clamping device 6 at the tip of the pushing arm 5, By rotating the pushing arm 5, the bicycle can be transferred between the lifting frame 2 and the storage location, and the bicycle can be placed and fixed on the mount and transferred between the lifting frame 2 and the storage location. Since there is no need to do this, it is possible to simplify the continuous loading/unloading of multiple bicycles and shorten the loading/unloading cycle time, compared to the conventional case in which a bicycle delivery stand is used.
