Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention comprises at least two platforms arranged one above the other and a base lowered relative to the normal entrance plane on one side of the base. and each platform is tiltably supported by a lateral pivot of a slider guided on a vertical rail extending upwardly from the base at an intermediate position relative to the length of the platform and maintained substantially parallel to each other. The two platforms are arranged in such a manner that the two platforms are substantially horizontal at their lower end positions, but are inclined so that the entrance side end of the platform adjacent to the entrance side is located upward at the upper end position. The present invention relates to a vehicle parking device driven together by hydraulic cylinders in alternating alignment with a normal entrance plane.

[Conventional technology]

One advantage of parking devices of the type described above is that a lowered upper platform, at the level of the normal entrance plane, is used as a parking space for short-term parking, for example in garages housed in the basement of office buildings. The provision of an upper platform makes it easier to use for the public, especially for a constantly changing number of users, and since this upper platform is approximately horizontal in its lowered end position, it is easy to drive over it and it is free from obstruction. I can walk without walking. The storage space above the lower platform is relatively restricted for walking, but for those skilled in parking regularly.
It seems that it can be used without much interference.

Even if the upper platform of the known parking device is in its lowered end position at the entrance height such that it appears as one continuous surface in relation to the lane, the adjacent similar parking device and the rest of the parking space, the lowered base Alternatively, vertical rails protruding upward from the pit give an annoying appearance. This leads to a deterioration of the usability of the upper platform for visual reasons, but on the other hand, it is also possible to use such a parking device as a submersible garage in the garden, in which case there are no other protruding parts. If you do, it will be advantageous. The proposal to guide the slider at the rising end position by installing a relatively long vertical rail in the garage pit would not be suitable for the garage pit, if such a construction type is possible considering the groundwater level. It would require a lot of money to dig deep and lower the area.

[Problem to be solved by the invention]

The object of the invention is to improve a parking level of the above-mentioned type in such a way as to avoid impairments due to vertical rails projecting upwards during operation on the upper platform, and at the same time to provide unrestricted rigidity and integrity of the device during all operating phases. It is to be.

[Means to solve the problem]

To achieve the above object, the parking device according to the invention is characterized in that the vertical rail extends to the level of the plane of the common entrance, and the length of the slider connecting the two platforms is fixed at the rising end position of the platform. The slider is at least equal to the length of the rail so that it is still guided by the upper part of said rail, and the hydraulic cylinders on both sides are connected with the ends of their piston rods to the bottom of the base and whose cylinders are It is characterized in that it is connected to the lower platform and that stop means are provided in the pivot path of the lower platform for limiting the upper inclined position and the lower horizontal position of the platform.

〔Effect of the invention〕

Compared to the prior art, this feature greatly simplifies the possibility of eliminating the upwardly projecting vertical rail so that in the lower end position only the topmost platform at the normal entrance height is visible. A parking device having a practical structure is obtained. This type of structure is of great importance for the arrangement of a series of multiple parking devices side by side and laterally adjacent along a common lane. According to the features of the invention, inspection is made very easy and thus gives the user the feeling that the parking device can be used without difficulty. In submerged garages of this type, the upper platform is flush with the plane of the entrance on all sides in its lowered end position. There are no protruding structural members. Furthermore, the bottom of the pit or base is flush with the lower edge of the lower platform and the lateral side walls of the lower platform, respectively.

This advantageous construction is especially advantageous because the lower platform extends at its rising end device at an angle downward from the normal entry plane, so that the slider on the vertical rail is still in the bit with the lateral pivot for mounting the lower platform. This is possible because it does not need to extend beyond the normal entrance height. As a result, the slider at least at its lower part still remains guided by the vertical rail,
Therefore, it is well supported. This is because precisely the above-mentioned difference between the length of the vertical rail (=pit depth) and the length of the slider stroke is used to stabilize the system.

Furthermore, an important stabilization aspect is that the most significant horizontal forces acting on the slider are restricted and localized to the part of the slider that is completely guided and protected by the vertical rails. Another aspect contributing to this purpose is a hydraulic cylinder having a piston rod at the lower end of the cylinder and connected to the side edge of the lower platform. Because of this construction, when the hydraulic cylinder is extended to move the device from its lower end position to its upper end position, the acting force of the cylinder supported on the base or bottom of the pit is equal to or less than the total length of its vertical stroke. The lower platform remains within the length of the vertical rail. These favorable support conditions are also valid for the inclined position of the lower platform, which position is limited by the stop means on the slider as follows. This means that these stopping means and the torque generated by the force of the hydraulic cylinders and acting on the platform through these stopping means remain within the support range of the vertical rail without compromising the stability of the parking device. limited to.

The upper end of the vertical rail 16 is shown in FIG. 2 so that the effective amount of overlap can be seen. Because of the overlap, the slider 17 is still guided by the vertical rail 16 in the raised end position of the platform.

Stop means 40 are used to limit the tilting position of the platform in the upper end position. The stop means 42 forms a safety stop and limits the horizontal end position of the platform in cases such as when no hydraulic holding force is available. However, during normal operation, the horizontal orientation of the platform in the lowered end position is limited by the horizontal bottom of pit 10.
