Reference numeral 51 denotes a relatively thick wire rope. The wire rope 51 has one end connected to the lower end of the shackle 47, extends straight down from the shackle 47, and is wound counterclockwise around the left pulley 29. Extend horizontally horizontally to the right, and the right moving pulley 33 is provided with a hanging pulley 35 in a counterclockwise direction.
Are wound clockwise, respectively. And
After extending downward from the suspension pulley 35, it is fixed to the intermediate wall 7 a when it is folded upward through an opening 53 formed at the lower end of the intermediate wall 7 a of the right pillar 7. The wire rope 51 is appropriately tensioned in a state where the right bracket 25 is suspended by a chain described later. For example, when the wire rope 51 is extended,
By turning the shackle 47, the extension of the wire rope 51 is adjusted, and after the adjustment is completed, the nut 49 is tightened to fix the height of the shackle 47.

Since the wire ropes 51 are provided as described above, all the paths are accommodated in the frame 3 and the elevating body 15. That is, in the wire rope 51, the section from the shackle 47 to the left moving pulley 29 is in the right space 5a of the left column 5, and the section from the suspension pulley 35 to the other end is the right column 7

As described above, the lifting body 15 is connected to the wire rope 5
1 and the chain 67, half of the load of the elevating body 15 is supported by the wire rope 51, and the other half is supported by the chain 67. The pulley 35 is suspended from the left pulley 29 of the wire rope 51.
Since the length of the section up to and including the wire rope 51 is invariable, the increase and decrease in the length of the wire rope 51 in the displacement section above the left moving pulley 29 and the increase and decrease in the length of the displacement section below the suspension pulley 35 are inversely proportional to each other. I do.

Therefore, when the chain 67 travels in the ascending direction of lifting the joint 41, the length of the upper displacement section of the wire rope 51 decreases by the same distance as the traveling distance. When the vehicle travels in the descending downward direction, the length of the upper displacement section increases by the same distance as the traveling distance. As a result, the elevating body 15 is moved up and down in a horizontal posture in accordance with the driving of the chain 67, and the rotation of the motor 57 is stopped and the chain 6
When the position 7 is fixed, the height of the elevating body 15 is also fixed.

Reference numeral 77 denotes a switchboard fixed to the lower surface of the motor mounting plate 55. Operation switches (not shown) and electric members such as the motor 57 and limit switches 71 and 73 are all provided on the switchboard 77.
Connected to the circuit inside. The two-stage parking device 1 is configured as described above.

Next, the operation of the two-stage parking device 1 will be described. In the initial state, the elevating body 15 is waiting at the lowered position shown in FIG. 2 or the raised position shown in FIG. Therefore,
When the lifting button of an operation switch (not shown) is pressed while the lifting body 15 is at the lowering position, the motor 57 rotates clockwise as viewed from the front, causing the chain 67 to travel in the rising direction. Thereby, the elevating body 15 is raised,
The switch pressing pin 42 presses the actuator 75 of the upper limit switch 73 almost at the same time when the lifting body 15 comes to the raised position. As a result, the rotation of the motor 57 stops, and the elevating body 15 stops at the ascending position. Entry / exit of the vehicle to / from the lower pallet 19 is performed in this state.

When the down button of the operation switch (not shown) is pressed in this state, the motor 57 rotates in the counterclockwise direction as viewed from the front, and the load of the elevating body 15 causes the chain 67 to travel in the down direction. Tolerate. As a result, the elevating body 15 is lowered, and the switch pressing pin 42 presses the actuator 75 of the lower limit switch 73 almost at the same time as the elevating body 15 comes to the lowered position. As a result, the rotation of the motor 57 stops, and the elevating body 15 stops at the lowered position. Car loading and unloading to and from the upper pallet 17 is performed in this state.

As described above, the two-stage parking device 1 is installed such that a substantially lower half of the frame 3 is located underground. Accordingly, the height of the ground portion is almost the same as the height of a garage made of a one-story building, but the space above the parking device can be effectively used, even though it is a two-stage type. This is particularly effective when the two-stage parking device 1 is incorporated in a part of a house in a three-story house or the like.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and there are changes in the design without departing from the gist of the present invention. Are also included in the present invention. For example, in the embodiment, two sets of wire ropes and chains are provided. However, depending on the form of the frame, only one set of the wire ropes and chains may be used, and a portion for fixing both ends of the wire rope is a frame. There is no need to have it, and any base concrete or other fixed part may be used. Further, the number of the respective pulleys arranged on both sides does not need to be limited to one.

Further, in the embodiment, the moving pulleys are arranged on both sides in the left-right direction. However, the moving pulleys are arranged on both sides in the front-rear direction as long as they do not hinder the entry and exit of the vehicle. It is also possible. In the embodiment, the chain is used as the driving member. However, the driving member in the present invention may be any member that can pull up / down one side of the elevating body. Is also good. The present invention is not limited to the pit type, and can be applied to various multi-stage parking devices having one or more pallets.

[0028]

As described above, in the multi-stage parking device of the present invention, the wire rope wound around the pulley supported by the elevating body has a function of suspending half of the load of the elevating body,
In cooperation with the driving member, the lifting member has a function of keeping the posture of the lifting member horizontal, so that the driving force for lifting the lifting member is sufficient with a strength corresponding to half of the load of the lifting member. As a mechanism for raising and lowering the elevating body, only a fixed-type wire rope, a traveling drive member on one side only, and a motor for traveling the drive member are sufficient. Simple structure is enough.

According to the second aspect of the present invention, a sprocket fixed to a shaft rotated by a motor is disposed above one side of the elevating body, and an endless chain as a driving member is wound around the sprocket. Since one end of the chain is connected to one side of the elevating body or the suspension pulley, and the weight is connected to the other end of the chain, the mechanism for elevating the elevating body can be composed of almost only general-purpose parts.

According to the third aspect of the present invention, the bracket protruding laterally from the elevating body is movably housed in the guide space extending in the vertical direction of the frame, and the moving pulley and the hanging pulley are supported by the bracket. Most of the wire rope is passed through the guide space of the frame. Therefore, since no special space is required for disposing the wire rope, the structure can be simplified.
