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 is in contact with the guide plate 60, as shown in FIG.
It is slidably in contact with the guide surface of 6. 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 a magnetic card into a card insertion slot provided in the hook unit stocker 26, which is illuminated by a blue lamp, and presses an entry button (not shown). The card reader reads the signal from the card and sends it to the computer, where the entry information is stored in the computer and an entry signal is sent from the entry button switch. Based on this signal, the computer first supplies a drive signal to the solenoid 52. When the solenoid 52 is driven and its output shaft moves to the left in FIG. 4, the engagement between the stopper surface 22a of the hook unit 2 and the stopper surface 58a of the cam 58 is released, and the lowest hook unit 2 62, side plate 4,
6 is 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 handlebars of the bicycle onto the hooks 10 and 12. The output shaft of the solenoid 52 instantly returns to its original position and presses into the recess 22 of the hook unit 2 that has fallen.
to lock. At this time, the lift 28 is waiting at the lowest position, and its horizontal rail surfaces 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 pantograph mechanism 80 is connected to the guide plate 62 of the lift main body 28a.
chuck mechanism 144' located at one end of the side;
is waiting a little to the right in FIG. 2 from the center of the main body 28a. The user manually pushes the bicycle toward the chuck piece 132 of the chuck mechanism. As a result, the regulated member 16a of the hook unit 2 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 counterclockwise about the support shaft in FIG.
a is inserted between chuck pieces 132 and 133. Next, according to the command from the computer, the motor 7
6 is driven, the rack gear 78 moves to the left in FIG.
33 moves toward the center of the lift body 28a.
In conjunction with the movement of the chuck pieces 132, 133, the hook unit 2 also moves the chuck pieces 132, 133 along the horizontal rail surfaces 68, 70 while suspending the bicycle.
133, and when the entire bicycle has moved below the lift main body 28a, the driving of the motor 76 is stopped. At this time, the other regulated member 14a of the hook unit 2 collides with one chuck piece of the other chuck mechanism 144', pushes the chuck piece against the elasticity of the coil spring, and the pair of chuck pieces inserted in between. Next, the lift main body 28a rises according to a command from the computer, and the lift main body 28a moves up and down to the roller guide rail 40a of the handle guide 40 of the vacant bicycle storage section.
When the horizontal rail surfaces 68 and 70 of a correspond to each other, the 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 motor is driven in accordance with a command from the computer, and the entire length of the pantograph mechanism 80' is extended, and the chuck mechanism 144' is connected to the horizontal rail surface of the lift body 28a.
8, 70, move to the right on Figure 2,
Handle guide 40 in the bicycle storage section on the third floor on the right side
go inside. This allows hook unit 2 to
moves 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' rise, and the hook unit 2 becomes free with respect to the chuck mechanism 144'.
As shown in the figure, due to its downward slope to the right, it moves toward the back of the bicycle storage section due to its own weight. In addition, the bicycle,
When the bicycle is placed in the bicycle storage section on the left side of FIG. 2, the bicycle is driven to the left in the manner described above by the pantograph mechanism 80 and the chuck mechanism connected thereto. The chuck mechanism 144' that sent the bicycle into the bicycle storage section is driven by the motor to return to a position approximately at the center of the lift body 28a, 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 lamp is on, inserts the card into the card slot,
Press 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 motor 76, the chuck mechanism moves to one end of the handle guide 40 on the third floor on the left side. Next, the tire guide 38 on the third floor on the left side is driven, and the tire guide 38 is tilted downward to the right. As a result, the bicycle moves to the right in FIG. 2 due to its own weight, and the restricted member 16a of the hook unit 2 collides with the chuck piece 132 of the chuck mechanism. The regulated member 14a is rotated about the shaft in the counterclockwise direction of rotation of the hour hand in FIG. 8 against the elasticity of the coil spring 138, and is inserted between the chuck pieces 132 and 133. Next, the chuck mechanism guides the bicycle under the center of the lift body 28a by driving the motor 76, and the drive of the motor 76 stops when the entire bicycle is located under the center of the lift body 28a. Next, the lift main body 28a descends, and the lift main body 28a
horizontal rail surfaces 68, 70 and gate guide plate 6
The roller guide surface of No. 2 coincides with the roller guide surface of No. 2. Next, the motor 76 is driven, 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 selects Hook 1 of Hook Unit 2.
Remove the bicycle from 0.12. Next, remove the magnetic card from the insertion slot and take the bicycle out for use.
When the vehicle is completely unloaded, the computer drives the motor 44 to raise the hook 50. As the hook 50 rises, the hook unit 2 on the guide plate 62 rises with the rollers 18 and 20 in contact with the guide plate 60. At this time, one of the side plates 6 comes into contact with the direction changing roller 64, and the side plates 4 and 6 rotate 90 degrees in the hour hand rotation direction in FIG. 4 about the rollers 18 and 20.
The recessed portion 22 is located on the left side in the figure. If the hook 50 continues to rise in this state, the inclined surface of the side plate 6 collides with the inclined surface of the cam 58, causing the cam 58 to move upward as shown in FIG.
The hour hand moves in the counterclockwise direction around the shaft 56,
When the cam 58 is inserted into the recess 22 of the side plate 6, the motor 44 is stopped by a signal from the limit switch 150. A large number of other hook units arranged in the case 42 are pushed up by the rise of the hook unit 2, and the whole is lifted by one hook unit. Next, the motor 44
is driven in the opposite direction until the limit switch 152 is turned on, and the hook 50 returns to its original lowered position.

Since the present invention is configured as described above, it is possible to store a large number of hook units, and moreover, it is possible to automatically take out the hook units one by one when necessary. This has the effect of improving the functionality of the automatic storage device.
