Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The invention relates to a parking device for a motor vehicle having a plurality of sets of motor vehicle platforms arranged one above the other and connected to each other, each of said platform sets Together, one platform of said set of platforms is adapted to be raised or lowered into an underground recess by a lift device to connect one platform to a common roadway, and further said sets of platforms are arranged in a line. Relating to things that are arranged in parallel with each other.

BACKGROUND OF THE INVENTION In a parking device of the above-mentioned type known from German Patent Application DE 31 45 370 A, a plurality of platform sets are arranged parallel to one another in a row. The upper and lower platforms of such a platform set are rigidly connected to each other and are raised or lowered by hydraulically driven lift cylinders arranged laterally of the platform set. During its raising and lowering movements, the platform is guided by rails or similar elements. In this case, the guide is configured to allow the platform to move up and down and at the same time to make a tilting movement.

In DE 24 15 522 A1, another set of platforms is disclosed which has an upper platform and a lower platform. These platforms are hinged to one another, and in this case also a tilting movement occurs at the same time as the lifting movement. Such platform sets are also usually arranged parallel to each other in rows. Both of these known parking devices are characterized in that each platform set has 19 suitable lifting devices constituted, for example, by hydraulic lift cylinders. The lift cylinder extends between the platform set and the floor of the underground recess in which the parking device is located. Furthermore, it is known that the pressure medium for a plurality of platform sets is probably generated by 19 common devices, and each platform set is assigned its own lifting device. It is also known in this case for example for three platforms to be combined with each other.

All parking devices of the aforementioned type are specifically provided for installation in underground garages. In this case,
The lower platform, which has been lowered into the underground recess, generally serves as a parking place for the vehicles of those working in the building, whereas the upper platform is designated for the vehicles of the rapidly changing public traffic. There is. Because of this type of application, lift devices are used almost infrequently.

German Patent Application DE 32 12 822 A1 shows another embodiment of a parking device in which a laterally movable lifting device is provided, the lifting device comprising a plurality of lift devices arranged one above the other. Can be assigned to a platform. However, such an arrangement is such that the platforms are not connected to each other to form a platform set, but are additionally operated by a plurality of lifting devices acting on the raised platform from above. Furthermore, with such an arrangement, the lifting device must be at least partially arranged in the movable space and special elements must always be provided for connecting the lifting device with the platform.

OBJECTS OF THE INVENTION It is an object of the invention to improve a parking device of the type described above in such a way that the balance between the costs for the lift device and the frequency of use of the lift device is significantly improved.

According to the measure of the invention taken to solve the aforementioned problem, only 19 lifting devices are provided for the plurality of platform sets; A lifting device, which is disposed perpendicularly to the roadway direction and is movable laterally, is arranged in the space between the underside of the lower platform and the floor of the underground recess.

Advantages of the Invention In contrast to the known system in which 19 common pressure medium generators are provided for multiple platform sets, the present invention provides only 19 lifting devices for multiple platform sets. . This lift device each time
It can be assigned to the platform group to be raised. It is clear that in the present invention several or all platform sets of the 19 parking devices are not raised at the same time. However, this is not a disadvantage in this type of use of the parking device, since it is rarely necessary to raise several platform sets at the same time.

In the invention, there is sufficient space between the underside of the lower platform and the floor of the underground recess for the lifting device in the lowered state. It is clear that this space requires only a small height, so that little additional space is required. Furthermore, according to the present invention,
The plurality of lift cylinders provided on the sides of the platform set in the conventional type can be omitted. The space required for such a lift cylinder can thus be saved. Moreover, the present invention requires only a small amount of horizontal space, as with conventional parking devices, and no additional vertical space is required.

The lifting device of the invention can be used for platform sets that are movable along rails and for platform sets that are pivotable about hinges or other guide members during movement. It is not important for the invention whether the platform is only raised during the lifting movement or whether it is also tilted.

A particular advantage of the invention is that no safety devices for the platform are required. The platform set is in the raised position only if the lifting device is below the platform set and is assigned to it. The lifting device can only be moved laterally if the platform set is in the lowered position.

Embodiment According to an advantageous embodiment of the invention, the lifting device is formed by a scissor device, which is supported on a moving frame and acts on the platform set from below by means of a liftable member. It has become. With such a scissor device, only little space is required in the folded state and a sufficient lifting height is achieved.

Embodiment As shown in FIG. 1, a plurality of platform sets 31 are arranged in parallel in an underground garage 23. Each platform set 31 has an upper platform 21
and a lower platform 4. Both platforms are connected to each other by struts 32. Each set of platforms 31 is entirely movable along a vertical guide 26. In the lowered state, each platform set 31 rests on a support 33 arranged at such a height that a space 2 is left below the lower platform 4 and the floor 3. The space 2, each platform group 3 with the lift device 1 folded
1, i.e. enough to move laterally.

As can be seen in FIG. 2, in the lowered state each upper platform 21 is at the level of the roadway 22, thereby allowing traffic. Only by raising the platform set 31 by means of the lifting device 1.
The lower platform also has a carriageway 22 on request.
It is also leveled to the height of . FIG. 2 shows an intermediate position in which the lower platform 4 has partially raised the set of 19 platforms receiving a motor vehicle.

Lifting device 1 essentially consists of a moving frame 5 which is connected to rails 2 via rollers 27.
It is movable laterally along 8. The mobile drive is not shown in detail. For example, a motor driving rollers 27 is supported on the moving frame. However, stationary motors, which are operated, for example, via a circulating rope, are also possible. In the illustrated embodiment, the moving frame 5
supports a hydraulic pump device 13 for driving both hydraulic cylinders 11 of the scissor device 34.

The scissor device 34 consists essentially of two scissor members 6.7.
The two scissor members are connected to each other by a hinge 12. Lower end 8 of scissor member 6
is held on the moving frame 5 by a hinge 29, whereas the lower end 9 of the other scissor member 7 is movable in the guide 10. It is clear that when the hydraulic cylinder 11 is loaded, the scissor device is erected and the respective platform set 31 is raised by the upper ends 14, 15 of the scissor members.

As can be seen in particular from FIG. 1, the upper ends 14, 15 are provided with supports 16, 17 whose length corresponds approximately to the width of the platform 4. This allows the scissor device to be constructed relatively narrowly. Guide 26
The scissors device does not need to have any special stability against lateral forces, since the platform set is sufficiently guided by the scissor device.

As can be seen in FIG. 3, supports 16, 17 support a roller 18 and a ring 19 at each end. Rollers 18 support the support profile of lower platform 4 from below, and rims 19 provide sufficient lateral guidance. Despite having a large play, sufficient opposing alignment is guaranteed. A supporting molded material 20 supports a molded material 30 fixed to the supporting molded material,
This molding forms the passable plane of the lower platform 4. In this case, it is advantageous if platform 4 has the same configuration with regard to supporting profile 20 and profile 30 as said upper platform 21 .

In order to be able to use the lifting device of the parking device according to the invention, the lifting device is made to run underneath the set of liftable platforms. The switched-on lifting device raises the platform set so that the lower platform 4 corresponds to the height of the roadway 22.

When it is desired to raise another set of platforms, first the set of platforms is released from the support section 20 and, in order to raise the other set of platforms,
The lifting device is moved laterally within the space 2 along the rails 28.

The scissor device described above is particularly suitable for platform sets in which the lower platform is only raised and not tilted during the lifting movement. The rollers 18 provide in this case four fulcrums between the lifting device 1 and the platform set.

However, it is also possible for the platform set to act on the upper end of the scissor device only at one or two points, provided that the platform set has further suitable guides during the upward movement. Such an arrangement is particularly suitable if the platform also performs a tilting movement during the lifting movement.
