Next, the operation of this embodiment will be explained.

A plurality of hook units 2 are arranged in a storage portion of the hook unit stocker 26 so as to be stacked upwardly. Each hook unit 2 has rollers 18,
20 comes into contact with the guide plate 60 as shown in FIG.
The upper surfaces of the side plates 4 and 6 are in slidable contact with the guide surface of the hook unit guide plate 66. As shown in FIG. 4, the lowermost hook unit 2 has a stopper surface 22a of its recessed portion 22 engaged with a cam 58.

First, a case where a bicycle is stored in a parking lot will be explained.

The user inserts the magnetic card into the card slot provided in the hook unit stocker 26 of the gate with the blue lamp on, and presses the entry button (not shown). The card reader reads the magnetic signal of the card and sends it to the computer, where the computer stores the parking information and also sends the parking signal from the parking button switch. This signal causes the computer to first provide a solenoid 52 drive signal. The solenoid 52 is driven,
When the output shaft moves to the left in FIG. 4, the stopper surface 22a of the hook unit 2 and the cam 58
is disengaged from the stopper surface 58a, the lowest hook unit 2 falls onto the guide plate 62, and the side plates 4, 6 are released from the restriction of the guide plate 66. The hook of the hook unit 2 on the guide plate 62 projects downward from the lower end of the case 42.
Next, the user hooks the bicycle handlebars 10,
Hook it on 12. The output shaft of the solenoid 52 returns instantaneously and locks the recessed portion 22 of the hook unit 2 that has fallen. At this time, the lift 28 is waiting at the lowest position, and its horizontal rail surface 68,
70 is located at the same level as the upper surface of the guide plate 62.

On the other hand, the chuck mechanism connected to the rod of the multistage cylinder 76 is located at one end of the lift body 28a on the guide plate 62 side, and the chuck mechanism 14 connected to the rod of the multistage cylinder 76 is
4' is waiting a little to the right in FIG. 2 from the center of the main body 28a. The user rides the bicycle,
The chuck piece 132 of the chuck mechanism is manually pushed in the direction. As a result, hook unit 2
The regulated member 16a pushes the inclined surface of the chuck piece 132. As a result, the chuck piece 132 resists the elasticity of the coil spring 138 and rotates in the counterclockwise rotating direction about the shaft 134 in FIG. 8, and the regulated member 16a is inserted between the chuck pieces 132 and 133. be done. Next, the multi-stage cylinder 76 is driven by a command from the computer, and the rod of the multi-stage cylinder 76 moves to the right in FIG.
Move toward the center of 8a. This chuck piece 13
2,133, the hook unit 2 also moves to the horizontal rail surface 68,70 while suspending the bicycle.
When the entire bicycle moves below the lift main body 28a, the driving of the cylinder 76 stops. At this time, the other regulated member 14a of the hook unit 2 is in contact with the other chuck mechanism 144'.
The chuck collides with one of the chuck pieces, pushes the chuck against the elasticity of the coil spring, and is inserted between the pair of chuck pieces. Next, the lift main body 28a is raised according to a command from the computer, and the roller guide rail 40a of the handle guide 40 of the vacant bicycle storage section and the horizontal rail surface 6 of the lift main body 28a are raised.
When 8 and 70 match, lift main body 28a
stops rising. Now, a case will be explained in which the bicycle storage section on the third floor on the right side of FIG. 2 is selected. In this case, the solenoid 130 of the chuck mechanism
is driven by a command from the computer, the elevating plate 122 is raised, and the interlocking relationship between the chuck pieces 132, 133 and the regulated member 16a of the hook unit 2 is released. Next, the cylinder 77 is driven by a command from the computer.
7 moves to the right as shown in FIG. 9B, and the chuck mechanism 144'
Along the horizontal rail surfaces 68, 70 of FIG.
Move to the right and enter the handle guide 40 of the bicycle storage section on the third floor on the right side. As a result, the hook unit 2 is moved from the lift main body 28a into the handle guide 40, and the rear wheel of the bicycle is placed on the tire guide 38. Next, in response to a command from the computer, the pair of chuck pieces of the chuck mechanism 144' are raised to free the hook unit 2 relative to the chuck mechanism 144'. Please note that the bicycle is
When the bicycle is placed in the bicycle storage compartment on the left side of the figure, the bicycle is driven to the left in the manner described above by the rod of the cylinder 76 and the chuck mechanism connected thereto. The chuck mechanism 144', which has sent the bicycle into the bicycle storage section, returns to the approximately central position of the lift body 28a by the drive of the cylinder 77, and then the lift body 28a is lowered to the lowest position. .

Next, a case where the user takes out the bicycle from the parking lot will be explained.

First, the user goes to the gate where the exit OK light is on, inserts the card into the card slot, and presses the exit button switch. The computer raises the lift body 28a and stops the lift body 28a at the floor from which the bicycle is to be taken out. Assume that the bicycle storage section on the third floor on the left side in FIG. 2 is selected. By driving the cylinder 76 as shown in FIG. 9C, the chuck mechanism moves inward of the handle guide 40 on the third floor on the left. As a result, the chuck piece 132 of the chuck mechanism is attached to the regulated member 16a of the hook unit 2.
As a result, the chuck piece 132 rotates about the shaft 134 against the elasticity of the coil spring 138 in the counterclockwise direction of rotation of the hour hand in FIG. 133. Next, the chuck mechanism guides the bicycle below the center of the lift body 28a by driving the cylinder 76, and the drive of the cylinder 76 stops when the entire bicycle is located below the center of the lift body 28a. Next, the lift body 28a
is lowered and the horizontal rail surface 6 of the lift main body 28a
8 and 70 coincide with the roller guide surface of the guide plate 62. Next, the cylinder 76 is driven, and the chuck mechanism moves to the left end of the lift body 28a in FIG. 2, and the bicycle moves into the gate.
The user pulls out the bicycle until the guide rollers 18 and 20 of the hook unit 2 come into contact with the guide plate 60. At this time, the regulated member 16a of the hook unit 2 engages with the hook 50. Next, the user removes the bicycle from the hooks 10 and 12 of the hook unit 2. Next, remove the magnetic card from the insertion slot and take the bicycle out for use.

When the computer completes delivery, the motor 44
to raise the hook 50. As the hook 50 rises, the hook unit 2 on the guide plate 62
is raised with the rollers 18 and 20 in contact with the guide plate 60. At this time, one of the side plates 4 comes into contact with the direction changing roller 64, and the side plates 4 and 6 touch the rollers 18 and 20.
It is rotated 90 degrees in the direction of rotation of the hour hand in FIG. 4, centering on , and the recessed portion 22 is located on the left side in the diagram. In this state, when the hook 50 continues to rise, the inclined surface 22b of the side plate 4 collides with the inclined surface of the cam 58, causing the cam 58 to
As shown in FIG. 4, when the cam 58 is inserted into the recess 22 of the side plate 4, the motor 44 is stopped by a signal from the limit switch 150. case 4
The large number of hook units located within the
Pushed up by the rise of hook unit 2,
The whole increases by one hook unit. The motor 44 is then driven in the opposite direction until the limit switch 152 is turned on, and the hook 50 returns to its original lowered position.

As described above, the present invention uses a pair of multi-stage cylinders to move the chuck mechanism, and has the advantage of being able to quickly control the movement of the bicycle in the horizontal direction.
