Moreover, the gear 14 attached to the rotating shaft 6 is connected to the motor 1.
It engages with the drive gear 16 of No. 5 and is driven to rotate. Further, this rotary shaft 6 is provided with a cheno wheel 1f, which drives cheno wheels 18 provided at both end positions of the upper and lower linear rails 2a, 2a of the rail 2. The upper Cheno wheel 18 is provided with a gear 21 that is coaxial with it and meshes with the rack gear 13, the lower Cheno wheel 18 is provided with a gear 19 that is coaxial with this, and the gear 19 is provided with a gear 20 that meshes with this. 20 rotates coaxial gears 21, and the gears 21 mesh with the rack gear 13 of the truck 5 to rotate the truck 5.
It is designed to move. That is, the structure is such that the direction of each of the carts 5 moving along the upper and lower linear rail portions 21 is the same direction as the direction in which the holding portion 8a of the rotating lift arm 8 moves along the side of the cart 5. There is.

Furthermore, the cheno wheels 18.18 on the front and rear sides of the mount 1 are the shaft 18.
It is fixed to both ends of the ° so that the front and rear chenos run at the same speed.

The number of teeth of the gear and the Cheno wheel is such that the time for the arm 7 to rotate % and the time for the trolley 5 to move one unit on the linear rail 2a are the same. Also, the lift arm 8 rotates following the arm 7 by the linker 9 in which the slider 9a is inserted into the deformed circular guide groove 10, so that the slider 9a approaches or moves away from the rotating shaft 6 side. As a result, the rotational speed changes, and the lift arm 8 connected to one arm 7 moves to the semicircular rail section 2 of the truck 5 on the lower extension rail section 21 in FIG.
The arm 7 rotates by % between the capture position of the operating protrusion 4 on the °b side and the release position of the operating protrusion 4 on the semicircular rail 2°b side of the trolley 5 on the upper extension rail portion 2°a. Rotates to follow.

The speed of the lift arm 8 is changed by the linker 9, and the rotational speed is lowered between the gripping position and the release position of the operating protrusion 4, thereby facilitating operation. The motor 15 described above is provided only on the ascending side of the cart 5, and on the descending side, the cart 5 is sent out by the upper gear 21 on the ascending side. Since the motor 15 is rotated, the motor 15 is not provided on the lowering side.

Further, at the upward branch of the branch rail 2°, there is an arc-shaped branch arm that curves downward at the branch between the semicircular rail 2b of the rail 2 and the extended rail portion 2°a of the branch rail 2°. 11 is pivoted toward the linear rail 2a of the rail 2, and the free end side of this branch arm 11 is connected to the linear rail 2a.

and lined up on the straight rail part 21 of the branch rail 2',
The carts 5 located at both ends are the gripping portions 8 of the lift arms 8.
The operating protrusion 4 on the front or rear side in the moving direction (indicated by arrows in FIGS. 1, 84, and 5) is slightly captured in FIG. When the motor 15 is driven from the state shown in FIG. 4 is completely captured by the holding portion 8a and rises while slidingly contacting the guide roll 3 within the semicircular rail portion 2°b. The rear operating protrusion 4 moves from the upper surface of the claw 12 to the upper surface of the branch arm 11 as shown in FIG. When abutting and distributing, the tip side of the claw 12 should be the 8th
Lift it up as shown in figure (b).

Then, since the next cart 5 is connected to the cart 5, the operating protrusion 4 on the front side of the next cart 5 extends together with the cart 5 sent by the gear 21, and moves by 2 degrees a. Therefore, the tip of the tip that has been lifted hits the lower surface of the claw 12 and passes under the branching arm 11 as shown in FIG. Rotate the arm 11 upward. Therefore, the operation protrusion 4 on the rear side of the truck 5 that has already been moved onto the branch arm 11 is moved to the semicircular rail 2 of the rail 2 as shown in FIG. 8(d).
While pushing it upward inward, the connection with the following truck 5 is released, and together with the lifting of the front operating protrusion 4 by the lift arm 8, the truck 5 is raised in a horizontal state.

As mentioned above, since the truck 5 is connected by the connecting member 5b which is vertically removable, it is easily separated from the previous truck 5 and continues to move on the extension rail portion 2°a.

In addition, after the branch arm 11 is no longer pushed up, the operating protrusion 4 on the rear side of the ascending cart 5 is replaced by the operating protrusion 4 on the front side.
: The guide roll 3 slides into the semicircular rail 2b to follow the cart 5 being pulled up by the lift arm 8, and the auxiliary arm 22 moves up near the center of the semicircular rail 2b.
The ascent is assisted by

During this time, the lift arm 8 is rotated following the linker 9, but as shown in FIG. Immediately after passing the longest distance from the rotational axis 6 of the eccentric circle, this is the point at which the rotational speed of the arm 7 begins to lag,
The operation protrusion 4 can be easily captured, and the connection member 5b can be easily disconnected from the following truck 5.

Furthermore, the rotational speed of the lift arm 8 decreases even after that, and the speed increases immediately after the slider 9a of the link par 9 passes the joint with the upper eccentric circle, and the rotation speed of the slider 9a decreases between the next eccentric circle and the slider 9a. The lift arm 8
releases the operating protrusion 4, so that the truck 5 does not collide strongly with the rear end of the truck 5 located on the preceding linear rail section 2°b, and does not rise with the connecting member 5b of the preceding truck 5. The connecting member 5b of the truck 5 is connected with sufficient margin.

This parking device is installed on the ground and has a lower straight rail 28.
There are cases in which a car is parked by entering the car in a direction perpendicular to the rail from a trolley 5 located in the upper part of the rail 28, and there are also cases in which the car is parked by driving onto the trolley 5 located underground and located in the upper straight rail 28 part. The parking devices may be arranged in double rows and the parking devices may be entered from each side, or one device C may always have one parking space open and the parking device C may be used from there to enter the other device.

[Effects] The parking device according to the present invention is configured as described above, and can park cars in upper and lower rows in a circulation manner, which contributes to effective use of space.

In addition, it is an excellent parking device especially when entrances and exits are narrow because it allows cars to enter from a direction perpendicular to the rails.
It can be installed on the ground and placed on a truck on the lower rail section, or it can be installed underground and placed on a truck on the rail section 4° above the ground. Alternatively, if it is set up in two rows so that there is always a trolley with no cars on one row, and this part is used as a space for boarding the other row, the other row may be along the wall. In addition, the movement of the bogie between the upper and lower rails is performed by a lift arm that rotates in synchronization with the movement time of the bogie on the straight rail, and the bogie is sent off from the straight rail at the position where the lift arm captures the bogie. Since the speed is synchronized with the speed of the vehicle, the handover of the trolley is carried out smoothly and there are fewer breakdowns, and there is also less vibration given to the cars on the trolley.

Furthermore, a branching arm provided at the branching point from the straight rail to the branching rail and a sorting claw provided at the free end of this branching arm separate the preceding bogie from the following bogie, resulting in failure. There are few
