The second vehicle-mounted base 23 is suspended from the first vehicle-mounted base 20 by four suspension shafts 27.

FIG. 5 is a vertical cross-sectional view showing the structure of the support portions 22 and 25, and FIGS. 6A and 6B are horizontal cross-sectional views showing the structure of the support portions 22 and 25, respectively. Here, the support portion connected to the screw shaft 7 is shown, but the same applies to the support portions at the other three corners. As shown in FIGS. 2 and 5 and 6 (a), the support portion 22 is composed of a screw nut 22a, a guide plate 22b, an angle 22c, and an angle mounting plate 22d. The screw nut 22a is a bearing that meshes with the screw shaft 7, and has a female screw formed on the inner surface of a cylindrical member and a flange integrally formed at the upper end position of the cylindrical portion. A guide plate 22b is fixed to the upper surface of this flange via a bolt. The guide plate 22b is a plate-shaped member, is made of a resin having wear resistance and rigidity, and has an opening at its center. As shown in FIGS. 5 and 6 (a), the guide plate 22b slides vertically inside the column 3 to guide the entire support portion 22.

Next, the angle mounting plate 22d is fixed on the guide plate 22b. The angle mounting plate 22d is a rectangular steel plate, and has an opening for passing the screw shaft 7 in the center thereof. The angle 22c is a support component that connects the angle mounting plate 22d and the frame 21, and the shape thereof is a thick steel material processed into a crank shape. The angle mounting plate 22d and the angle 22c may be integrally formed by casting, and must be rigid enough to withstand at least the wheel loads loaded on the first and second vehicle mounts 20 and 23. Four sets of such support portions 22 are provided in the first vehicle-mounted stand 20 corresponding to the screw shafts 6 to 9.

Next, as shown in FIGS. 2 and 6 (a), the frame 21 is a solid steel member having a rectangular cross section, and the front and rear end portions of the floor plates 20a and 20b of the vehicle-mounted base 20 are formed by, for example, It is fixed by welding and is connected to the left and right angles 22c. A bearing 26 is attached to the side surface of the angle 22c. The bearing 26 is a cylindrical sliding bearing whose central axis is vertical, and the suspension shaft 27 is inserted therein. The suspension shaft 27 is a cylindrical steel material, and has a length necessary to store the vehicle on the second vehicle-mounted base 23 with a predetermined distance from the bottom surface of the first vehicle-mounted base 20. Male threads are formed on both ends of the suspension shaft 27. The bearing 26 engages with a locking nut 27a provided at the upper end of the suspension shaft 27 and serves to suspend the second vehicle-mounted base 23. The bearing 26 and the suspension shaft 27 thus configured are provided on each support portion 22 of the first vehicle mount 20.

Next, the support portion 25 that holds the second vehicle-mounted base 23 will be described with reference to FIGS. 2, 5 and 6B. Unlike the support portion 22, the support portion 25 does not have a screw nut, and is composed of a guide plate 25b, an angle 25c, and an angle mounting plate 25d. The guide plate 25b and the angle mounting plate 25d are the same as those of the support portion 22. On the other hand, the angle 25c is different in shape from the angle 22c. That is, the angle 25c has a crank shape in cross section along the center line thereof, but an L-shaped holding portion having the same width as the frame 24 is formed in a portion connected to the frame 24. The angle mounting plate 25d and the angle 25c may be integrally formed by casting, as in the case of the support portion 22.

As shown in FIG. 6B, the frame 24 is provided with a groove 24 a and a flare 24 b having a U-shaped cross section. The frame 24 is formed by bending a steel plate, and the flare 24b is an ear-shaped portion that contacts the edges of the floor plates 23a and 23b and the treads 23c and 23d of the second vehicle-mounted stand 23. The front edge portions of the floor boards 23a and 23b are fixed by an inner flare 24b as shown in FIG. 6 (b). Further, the treads 23c and 23d are fixed to the flare 24b outside the frame 24. On the other hand, the vertical portion of the angle 22c of the first support portion 22 projects from the angle 25c of the second support portion 25 toward the center line side of the multi-level multi-story parking apparatus 1.

Next, as shown in FIGS. 2 and 6, a bearing 28 is fixed to the side surface of the angle 25c coaxially with the bearing 26. The bearing 28 is a cylindrical bearing whose central axis is vertical, and unlike the bearing 26, supports the suspension shaft 27 and fixes it. The bearing 28 is scissored by two sets of locking nuts 27b attached to the lower end of the suspension shaft 27, and the suspension shaft 27 supports the support portion 25 upward through the bearing 28. The bearings 28 having such a configuration are provided on the respective support portions 25 of the second vehicle-mounted base 23.

The columns 2 to 5 are formed by bending a steel plate so that the cross-sectional shape thereof becomes a rectangular tube shape as shown by the chain double-dashed line in FIG. 2, but the narrow slits 2c to 5c are formed. I have. As shown in FIG. 6, for example, the slit 3c has a width such that the angles 22c and 25c can move up and down, and a person does not directly touch the components of the screw shafts 6 to 9 and the supporting portions 22 and 25. It is the one.

To assemble the multi-level multi-story parking apparatus 1 having different vehicle widths and inter-axle dimensions, the corner blocks 2a to 5a may be fixed to the floor surface at specific positions as shown in FIG. The motor units 13 and 15 are not limited to the positions shown in FIG. 4, and may be mounted at positions close to any two sets of the four screw shafts 6 to 9. Further, as shown in FIG. 1, limit switches 28a to 28c are attached to the side surfaces of the support column 5 in this order from the floor surface upward depending on the height of the vehicle to be stored. Further, an elevating switch 29 is attached to the side surface of the column 4. The elevating switch 29 has a raising button and a lowering button, and is a switch for instructing the opening and closing of the power source of the motor units 13 and 15 and the rotating direction.

The operation of the multi-tiered multi-level parking device 1 thus configured will be described. Now, as shown in FIG. 2, it is assumed that the frame 24 of the second vehicle-mounted base 23 is lowered to near the floor surface, and the first vehicle-mounted base 20 is stationary above. In this case, in order to lower the first vehicle mount 20, the lowering button of the lifting switch 29 is operated. Then, the motor units 13 and 15 rotate synchronously in the same direction, and as shown in FIG. 4, the rotational force of the sprockets 13a and 15a is transmitted through the chains 14 and 16 to the sprockets 6b and 9b of the screw shafts 6 and 9, respectively. Be transmitted to.

Then, the slew shafts 6 and 9 rotate, and the rotational force thereof is transmitted to the sprockets 7a and 8a of the front screw shafts 7 and 8 via the chains 10 and 11, respectively. Therefore, the four screw shafts 6 to 9 rotate in the same direction, and the four screw nuts 22a of the first supporting portion 22 simultaneously descend. Therefore, the first vehicle-mounted base 20 is lowered. In this case, the suspension shaft 27 is stationary with the second vehicle-mounted base 23, and the bearing 26 slides on the suspension shaft 27 and descends. Eventually, the frame 21 and the supporting portion 22 are housed in the groove 24 a of the frame 24 of the second vehicle-mounted stand 23. The floor boards 20a and 20b of the first vehicle-mounted stand 20 are also stored in the floor boards 23a and 23b of the second vehicle-mounted stand. Therefore, the first vehicle-mounted base 20 is placed on the second vehicle-mounted base 23.

Now, FIGS. 7 and 8 are explanatory views showing a situation in which a plurality of vehicles enter and leave the three-stage multi-level parking apparatus 1a. FIG. 7A shows a state in which the first vehicle-mounted base 20 is stacked on the second vehicle-mounted base 23 as described above and is in close contact with each other. In this case, the floor boards 20a and 20b of the first vehicle-mounted stand 20 do not rise above the floor surface, and the vehicle can be easily stored through the treads 20c and 20d.

As shown in FIG. 7 (a), when the three-stage multi-level parking device 1 a is empty, both the first and second vehicle-mounted bases 20 and 23 are descending to the floor surface. The vehicle can enter the other three-dimensional parking device provided further behind the three-stage multi-dimensional parking device via the first vehicle-mounted stand 20.

Next, the first vehicle is stored in the first vehicle-mounted stand 20. When the up button of the up / down switch 29 is operated, the motor units 13 and 15 rotate in the up direction, and the first vehicle-mounted base 20 moves up due to the rotation of the screw shaft, as shown in FIG. 7B. Eventually, the limit switch 28b operates and the motor units 13 and 15 stop. Then, as shown in FIG. 7C, a second vehicle can be stored in the second vehicle-mounted stand 23.

Next, as shown in FIG. 8A, the second vehicle is stored in the second vehicle-mounted stand 23. Then, when the up-and-down switch 29 is operated again, the first vehicle-mounted base 20 starts to further rise as shown in FIG. 8 (b). Then, in FIG. 2, the bearing 26 of the support portion 22 abuts on the locking nut 27a. When the first vehicle-mounted base 20 is further raised by the rotation of the screw shafts 6 to 9, the second vehicle-mounted base 23 is suspended by the suspension shaft 27 and is raised. At this time, since the guide plate 25b of the second support portion 25 slides on the inner surfaces of the columns 2 to 5, the second vehicle-mounted table 23 ascends without vibrating in the front, rear, left, and right directions. Eventually, the limit switch 28c provided on the uppermost part of the column operates to stop the motor units 13 and 15.

In order to further store the third vehicle, the vehicle may be stored directly on the floor as shown in FIG. 8C. To unload each vehicle, the procedure shown in FIGS. 7 and 8 is reversed and the vehicle is unloaded.

By arranging the multi-stage multi-story parking apparatuses 1 in a row, more vehicles can be stored. That is, the first or second vehicle-mounted table 20 or 23 in which the vehicle is stored is raised to the state as shown in FIGS. 7 (c) and 8 (c), and another multi-stage type is provided behind this. A large number of vehicles can be put in and out of the multi-story parking apparatus 1 by passing the floor surface of the front multi-story parking apparatus 1.

Further, in the present embodiment, two vehicle-mounted bases 20 and 23 are provided so that three vehicles can be stored, but four or more vehicles can also be stored. In this case, a support portion similar to the support portion 22 having a screw nut is provided on the first vehicle-mounted platform located at the uppermost portion, and the second, third, ... Nth vehicle-mounted platform located below the support portion 22. Is provided with a support portion similar to the support portion 25. Then, another suspension shaft is used to suspend the second and subsequent vehicle mounts. With such a connecting mechanism, four or more vehicles can be stored.

For example, in order to realize a five-stage multi-level parking device using such a configuration, first, second, third, and fourth vehicle mounts are sequentially provided from the upper part to the lower part. Install a screw nut on the support of the first vehicle mount. Further, the first vehicle-mounted base suspends the second vehicle-mounted base via the first suspension shaft. Similarly, a bearing similar to the support portion 22 shown in FIG. 2 is provided on the second vehicle-mounted base. Then, if a bearing is provided at that angle on the third vehicle-mounted base and the second suspension shaft is fixed, the second vehicle-mounted base can suspend the third vehicle-mounted base. Similarly, the third vehicle-mounted platform suspends the fourth vehicle-mounted platform in the same manner. If the floor plates of the vehicle mounts are configured such that the widths of the vehicle mounts are widened in order from the upper to the lower vehicle mounts, the first to fourth vehicle mounts can be stacked on the floor surface. The cross-sectional shape of the frame that holds each floor plate must be changed in sequence.

Further, in such a multi-level multi-story parking system, the screw shaft and the pillar are fixed to the floor surface through independent corner blocks, respectively, so that the vehicle width and the dimension between the axles can be adjusted. It is possible to realize a multilevel parking system that can be equipped with a vehicle-mounted stand of any size. Further, since the columns are fixed to the four corners of the installation surface of the multi-story parking system, the multi-story parking system is not likely to fall down even if it receives a vibration due to an earthquake or an unexpected vehicle collision.

[0037]

[Effect of the device]

 As described in detail above, according to the present invention, since the first vehicle-mounted platform located at the upper portion is configured to suspend the vehicle-mounted platform located at the lower portion via the suspension shaft, three or more vehicle-mounted platforms are provided. Vehicles can be stored. Even if such a multi-tiered multi-level parking device is installed on the ground, each vehicle can be sequentially loaded and unloaded. Further, since this multi-stage type three-dimensional parking apparatus can be installed on a floor slightly larger than the first vehicle-mounted stand, it has an excellent effect that the effective floor area can be made larger than the land area. If they are installed in the same family or in the same office, management will be easier, and if the storage location is specified based on the frequency of use of each vehicle, it will reduce the trouble of handling.
