DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an underground storage type double-level parking device, which is extremely easy to configure the underground storage section and install the device, has a simple overall configuration, can be provided at low cost, and is durable. It is characterized by improved gender and appearance.

Conventionally, the present applicant has provided a double-tiered parking device of this type in accordance with Japanese Patent Application No. 56-37528 (see Japanese Patent Application Laid-Open No. 57-15765).

The above-mentioned two-level parking device suspends and fixes cross beams at the required intervals on the upper end of the opposing wall that constitutes the underground storage area.
An elevating body consisting of upper and lower pallets connected near the four corners by struts of appropriate length is provided between the cross beams, and one end of a chain is fixed to each of approximately the four corners of the lower pallet, and the chain is Each is suspended from a guide sprocket installed on the cross beam above the anchoring part, and can be rolled up evenly by a motor, and there is no need to erect a fixed column that protrudes from the underground storage part to the ground surface. It has many advantages, such as being extremely easy to configure and install in the storage section, being economical, and having a good appearance.

The present invention is further characterized in that the drive shaft portion of the device, which is subjected to the most force, has been improved to improve its durability and appearance.

An embodiment of the present invention will be described in detail below with reference to the drawings.

The underground storage section a is constructed by appropriately excavating the ground surface. That is, in the underground storage part a of the present invention, it is only necessary to erect an auxiliary column 17 inside to absorb the deflection of the beam, and if the length of the column can be adjusted and fixed, the bottom foundation concrete etc. Accurate leveling is not required, the labor for installation is greatly reduced, and the accuracy of parts manufacturing is also greatly reduced.

In other words, a wall (b) of a length corresponding to the number of cars is excavated approximately the length of the car, and a wall (b) of a length corresponding to the number of walls is constructed with concrete or the like on both sides.
It is only necessary to lay a simple reinforced bottom concrete at the part that constitutes b' and supports the auxiliary column 17.

Next, cross beams 1 and 1a are suspended from the upper ends of the opposing walls b and b' at a required interval, and both ends of the cross beams are completely fixed to the walls b and b'.

Further, between the upper cross beams 1 and 1a, support columns 2, 2a, 2b and 2c of appropriate length are provided near the four corners, respectively.
An elevating body c is provided which consists of an upper pallet 3 and a lower pallet 4 which are connected to each other.

In the case of the embodiment shown in the drawings, sloped surfaces 1b are provided at the ends of the cross beams 1 and 1a, respectively, so that there is no problem even if a car accidentally runs onto the cross beams. , and further the elevating body c
The tips of chains 5, 5a, 5b, and 5c are fixed to approximately four corners of the lower pallet 4 constituting the lower pallet 4.

In the case of the embodiment shown in the drawings, chain adjusters 6 are provided at the fastening portions of the distal ends of the chains 5, 5a, 5b, and 5c, respectively.
The structure is such that the lengths of b and 5c can be adjusted.

Next, the chains 5, 5a, 5b, and 5c are connected to the guide sprockets 7, 7 provided on the inside of the cross beams 1 and 1a, respectively, above the fixing parts with the lower pallet 4.
a, 7b, and 7c, and is configured to be able to be evenly hoisted by a forward/reverse rotation motor 8.

That is, in the present invention, support frames 15 and 15a are provided below one end of each of the cross beams 1 and 1a at positions that do not interfere with the elevation of the elevating body c, and a drive shaft is provided below between the support frames 15 and 15a. 9 is pivotally supported, and winding sprockets 10, 10a, 10b are engaged with chains 5, 5a, 5b and 5c suspended from the guide sprockets 7, 7a, 7b and 7c near both ends of the drive shaft 9.
and 10c are provided, and a winding sprocket 11, 1 is provided near the lifting body C below each winding sprocket 10, 10a, 10b and 10c.
1a, 11b and 11c are provided and the chains 5, 5a, 5b and 5c are wound around the sprocket 1.
1, 11a, 11b and 11c from above and suspended from the lower end surfaces thereof.
A, 10b and 10c are suspended from below to their upper end surfaces.

Further, a drive sprocket 12 is provided on the drive shaft 9, and a drive sprocket 12 is provided between the drive shaft 9 and a drive sprocket 13 provided on the drive shaft of the forward/reverse rotation motor 8 provided above the drive shaft 9 and below the cross beams 1, 1a. Chain 13a is suspended.

The above-mentioned forward and reverse rotation motor 8 is equipped with a speed reducer and a brake, and the raising and lowering control of the elevating object c by the forward and reverse rotating motor 8 is performed by a switch 14, and the upper and lower limits of the elevating object c are controlled. is performed by a detection switch provided in advance on the cross beam 1. In the figure, reference numerals 16 and 16a indicate reinforcing materials for the support frames 15 and 15a.

In the present invention configured as described above, the drive shaft 9 and the forward/reverse rotation motor 8 are provided in the underground storage part a.

Therefore, the upper pallet 3 can be made to have the same size as the entire opening of the underground storage section a, allowing vehicles to be taken in and out from both ends, and there is no protrusion on the ground surface when the elevating body c is stored. This has an effect of good appearance, and furthermore, the distribution of the force applied to the drive shaft 9 to which force is applied becomes ideal, and its durability is improved.

In other words, for example, the patent application filed by the applicant
In the case of the drawing embodiment shown in No. 56-37528 (see Japanese Patent Application Laid-open No. 57-151765), the sprocket for hoisting the chain provided on the drive shaft has a sprocket for hoisting the chain from below on its upper end surface. Since the chain is suspended, a pulling force is applied to the drive shaft through the sprocket toward the elevating body. Furthermore, since the motor is provided closer to the elevating body than the drive shaft, and the drive chain is suspended between the sprocket provided with the drive shaft and the drive sprocket provided on the drive shaft,
In addition to the force pulled toward the elevating body, a similar force is applied to the drive shaft via the drive sprocket.

Therefore, it is necessary to make the above-mentioned drive shaft thick so that it does not bend, and it is necessary to attach the supporting parts at both ends very firmly, and the bearings that make up the supporting parts at both ends must be strong or they will be damaged. There were similar drawbacks.

In this respect, in the present invention, the chains 5, 5a, 5b and 5c are wound around the hoisting sprockets 10, 10a, 10b and 10c of the drive shaft 9 and suspended from below to the upper end surface via the sprockets 11, 11a, 11b and 11c. As a result, a force F is applied to the drive shaft 9, as shown in FIG. On the contrary, a forward and reverse rotation motor 8 is provided above a drive shaft 9, and a sprocket 1 provided on this drive shaft
3 and the drive sprocket 12 provided on the drive shaft 9, the drive chain 13a is suspended between the drive sprocket 12 provided on the drive shaft 9.
A force F that is pulled substantially upward is applied via the . That is, forces F and F' are applied to the drive shaft 9 in opposite directions, canceling each other out, without applying forces in the same direction, and the force applied to the drive shaft 9 is reduced.

Therefore, the drive shaft 9 can be made thinner, and there is no need to pay much attention to the strength of both end support bearings and their mounting parts, and the entire drive unit can be simplified, damage is prevented, and durability is improved. Moreover, when the elevating body c is stored, there is no protrusion from the ground surface, so the appearance can be improved.
