Abstract

1. A parking device for motor vehicles, having two platforms (8, 9) one above the other, which form useable parking places in all operating positions for the vehicles, whereby a common drive-in entrance (15) is aligned with one or the other platforms selectively through tilting and lifting or lowering of both platforms, there being provided a lifting and tilting device for the platforms, basically comprising a rail system with curved tracks (1, 2, 3) for rollers (4, 5, 6), laterally positioned with respect to the parking places and situated between the platforms and the stationary supports (10), and a lifting drive (14) extending over the length of the rail system, characterised in that the rail system has a plurality of tracks (1, 2, 3) of which two (1, 3; 2) have differing centres of curvature and work in conjunction with associated rollers (4, 5, 6) respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an automobile keying device having two platforms arranged one above the other and a lifting/lowering device for these platforms, the lifting/lowering device comprising: relates to a type of rail mounting device forming a curved track of rollers or the like on both sides of the platform.

A parking device of this type is described, for example, in German Patent Application No. 2913661. In this case, the rollers, which are arranged stationary on the rail system and are guided by the rail system, are supported on Zorad foams that are rigidly connected to one another.

Due to the curvature of the track, both platforms are tilted when lifted from a substantially horizontal downward position force ≧ upward position, and the entry of the vehicle into the lower platform takes place in a downwardly inclined condition.

The advantage of such a construction is that by relatively simple means the platform also performs a tilting movement during the lifting movement, making effective use of space and reducing the required lifting distance. .

However, in the known /e-King device.

The rollers or similar, e.g. slides, are arranged at an offset in height, and for this purpose the height of the roller device, cooperating with the same track, has to be increased considerably, 9 and both platforms are lowered. Even in this position, the rail system projects upwardly well beyond the height of the access road surface.

The object of the invention is to improve the /e-king device of the type mentioned in the first place so that the height of the rail device is as small as possible and the lifting and lowering movements are carried out smoothly. .

To achieve this objective, the invention provides that each rail device has a number of tracks next to each other, each track cooperating with one roller or the like.

In the following, the configuration of the present invention will be specifically explained with reference to embodiments shown in the drawings.

In the illustrated embodiment both platforms 8 and 9
are rigidly connected to each other by stays 12.

The connecting member 13 reduces the load on the stay 12, and is driven by a jacking device 14 configured as a hydraulic cylinder. This jacking device 14 is connected to the upper platform 9 and to the frame 10 of the parking device. Entry/exit surface 15 of the lower platform 8
At the opposite end a synchronizer is arranged, which has an axis 17 extending over the entire width of the platform and which is rigidly connected to one end of the link 18. 1st Sumire of Link 18 1st Sumire is Support 2
It is slidable along a guide 19 formed at 0.

This synchronizer prevents the lower platform 8 and thus the upper platform 9 from tilting from side to side.

Three roller supports δ and 6 are supported on the stay 12. In this case, the rollers 5 and 6 are arranged at approximately the same height Gi, while the roller 5 is arranged below.

The track member 7, which is constructed as a cast product, is fixed at its lower end to the frame 10 of the parking device;
The upper end portion is connected to a stay 11. The stays 11 increase the rigidity of the track member 7.

The common track member 7 has a separate track 1, 2, 3 for each roller feeder 5, 6. The tracks 1 and 3 are in this case formed by the outer edges of the track elements 7 and have an approximately constant mutual spacing corresponding to the roller spacing and 60 mm spacing.

Of course, this mutual difference is the slope of the platform.
It must be set so that it can be played.

A track 2 for the roller 5 is formed between the tracks 1 and 3, but the track 2 has a different shape from the tracks 1 and 3. Although all tracks 1, 2 and 3 are curved and have a center of curvature on the opposite side from the entrance/exit surface 15, the center of curvature of track 20 is significantly greater than the center of curvature of tracks 1 and 3. It is located downwardly so that the platform performs the desired tilting movement during the upward movement.

By means of a rail arrangement on a common track member, it is possible to force platforms 8 and 9 into quite specific movements. In particular, 1, for example, lifting and lowering movements can be performed relatively softly and smoothly. During vehicle entry and exit, both platforms and the platform are in close contact with the entry/exit road surface, and the space is utilized very effectively.

A particular advantage of the invention is that the platform A is guided reliably even though the distances between the rollers 4 and 6 and the roller 5 are relatively small. Due to the small distance between the rollers in the vertical direction, the rail arrangement is short and only projects slightly above the entrance/exit road surface 15.

If desired, it is also possible for the rail arrangement not to protrude from the access road surface 15 at all. That is, if the entire rail device is shifted to the side opposite to the entrance/exit road surface 15, the vertical movement of the platform is small in this range, so the space required for the rail device in the vertical direction is also reduced.

The invention may be implemented in various ways, but of course each of these rollers must be forcedly guided from both sides. It is also possible to use one roller above and two rollers below.

As is clear from the plan view of FIG. 2, the dimensions in the direction perpendicular to the drawing plane of FIG. 1 are small.

Even if the common track element has symmetrical tracks for the rollers of adjacent parking devices, the dimensions of the track element are small.

Generally, raceway members are manufactured as cast products.

However, it may be produced in other formats. It is also advantageous for the track elements to be stationary, but in special cases it is also possible to connect the upper and lower platforms by track elements and to arrange the rollers in a stationary manner.
