Description

The invention relates to a parking device for motor vehicles with at least two platforms, which are movably mounted at one end at a fixed distance from one another on a frame or a structural part and can be moved by means of a drive such that the other end of one of the platforms can optionally be connected to an access, the lower platform being held on the upper platform by tension members. Such parking facilities are known for example from DE-AS 28 34 498.

Since a drive mechanism, for example a hydraulic cylinder, must be arranged to move the platforms outside the same on both sides you need space for the drive between the platforms and a building wall or between neighboring platforms. In addition, in order to achieve synchronism with uneven loading of the platforms, it is necessary to take special measures, for example in the form of additional torsion shafts, toothed racks or joint scissors.

The object of the invention is to improve a parking facility of the generic type in such a way that the platforms make optimal use of the space available in the building.

This object is achieved according to the invention in a parking facility of the type described in the introduction in that one arm is arranged above each side edge of the upper platform in vertical planes running parallel to the side edges and one end is perpendicular to a horizontal one above the mounted end of the platforms is pivotally mounted on the frame or structural part to the axis of rotation extending to the side edges, that the arms arranged on opposite sides of the platforms are rigidly connected to one another, that the upper platform is held by means of a tension element at the free end of both arms and that the drive is on the arms attacks and pivots between different angular positions about the axis of rotation.

All drive links are upper in this construction arranged half of the upper platform so that no space for the drive is required next to the platforms. Only the tension members, for example the ropes or chains, connect the two superimposed platforms or the upper platform and the arm to one another - these tension members, however, require an extremely small amount of space, so that practically no storage space is lost due to the arrangement of these tension members. Due to the rigid connection of the two arms to each other, complete synchronization of the platform movement is achieved even with uneven loading, ie no additional measures for platform stabilization are necessary. This also makes it possible to utilize the space available in the building much better than in the case of arrangements in which the synchronization must be achieved by additional devices.

The space above the upper platform is necessary anyway in order to be able to accommodate a motor vehicle parked on the upper platform when the platforms are raised, so that no additional space is required by the arms and their drive.

It is particularly advantageous if the two arms are connected to one another by a torsionally rigid cross member running along the axis of rotation. The result is a U-shaped lifting element which is pivotally mounted on the back of the platforms, the platforms being attached to the free ends of the arms. Alone through Swiveling this U-shaped lifting element, the desired connection movements of the platforms to the driveway can be realized.

It is advantageous if the traverse is arranged at a distance above the upper platform that is greater than the height of the hood of a motor vehicle to be parked. As a result, the entire space of the upper platform can also be used for parking a vehicle, the transverse traverse lies above the hood of a parked motor vehicle and does not interfere.

It is still convenient if the arms are less than half the length of the platforms. As a result, no additional space is required even in the vertical direction with a relatively large pivoting angle of the arms.

The tension members can extend obliquely from the attachment to the arm to the attachment to the platform towards the free end of the platforms. Thereby, the access-side attachment point of the tension members can be in the vicinity of the _Z ufahrt move, so that the platforms are kept stable in its storage and at the fastening point of the tension member.

In a first preferred embodiment it is provided that the platforms are mounted so as to be pivotable about a fixed axis running parallel to the axis of rotation. The pivoting movement of the arm is thus transferred into a pure pivoting movement of the platforms, the pivoting angle of the platforms being different from that of the arms due to the oblique course of the tension member, so that the angle of rotation of the platform is determined by fastening the tension member at a different distance from the axis of rotation that corresponds to a certain angle of rotation of the arm. As a result, the connecting movement of the platforms to the driveway can be adapted to the respective structural conditions.

In a further preferred exemplary embodiment, the platforms are pivotally mounted about axes running parallel to the axis of rotation on a slide which can be displaced in a vertical guide. A second tension element is held on the arm and engages between the supported end and the attachment of the first tension element to the upper platform. The upper platform thus hangs on the arm via two tension elements which engage at a distance from one another, the slide only serves to guide the platforms when the vertical displacement occurs.

It is particularly advantageous in this embodiment if the attachment points for the first and the second tension element on the arm are at different distances from the axis of rotation of the arms. As a result, the arm-side fastening points of the tension members perform different paths when the arm is pivoted, so that the platforms attached to it also experience a pivoting movement in addition to the vertical movement. As a result, for example, the platforms can run horizontally in the lower position, while in the upper position they are raised towards the approach side. As a result, the overall displacement of the platforms can be reduced, since with raised, inclined platforms, the motor vehicles can already drive onto the lower platform if it has not yet reached the access height over its entire length.

It is advantageous if the second traction element is a rigid rod which is rotatably articulated both on the arm and on the upper platform and which can absorb not only tensile but also compressive forces. This ensures that the platform is also carried in a stable manner when it is loaded only at the end on the approach side, for example when a motor vehicle is being driven up.

The arrangement shown forms a particularly space-saving and advantageously mountable drive for platforms, in particular for platforms which have more than one parking space next to one another. It can be sufficient here to provide a platform with two or even three adjacent storage spaces with only two arms, each of which is located above the side edges of the platform, the crossbar connecting the arms then extending over the entire width of the platform. Only by appropriately stable The construction of the unit consisting of the arms and the crossbar gives a drive with a simple construction, which at the same time fully compensates for uneven loads on the platform, for example by driving with only one motor vehicle, without additional structural measures being necessary. Of course, a correspondingly stable design of this structural unit is necessary for this, that is, the arms and traverse must be resistant to bending and torsion. It is also possible to arrange one arm each with an arrangement with several adjacent parking spaces above the border line between adjacent parking spaces, the arms being connected to one another via cross members to form a rigid structural unit.

A further advantage is that the space is not needed immediately above the arms for the drive, so that in the rear top corner of the building space remains at ^g for installing controls and drive parts, such as a hydraulic power, or for on-site installations .

The following description of preferred embodiments of the invention serves in conjunction with the drawing for a more detailed explanation. Show it:

• Figure 1 is a perspective view of a parking facility with a drive comprising two rigidly interconnected arms.
• Fig. 2 is a schematic side view of the parking facility of Fig. 1 with raised platforms;
• .Fig. 3 is a view similar to FIG. 2 with the platforms lowered;
• Fig. 4 shows another preferred embodiment of a parking facility in a representation corresponding to Fig. 2 and
• Fig. 5 shows the parking facility of Fig. 4 with lowered platforms.

The parking facility shown in FIG. 1 is arranged in a special structure, which has a floor 1, a vertical rear wall 2, a front wall 3 and a horizontal access 4 which merges into the front wall 3 above the floor 1. A ceiling 5 adjoins the rear wall 2 on the upper side, so that overall a space for receiving a parking facility that can only be reached via the driveway 4 is formed. This space can be limited in the lateral direction by side walls, not shown in the drawing, the distance between which can be so large that several similar parking facilities can be set up side by side.

The parking facility itself comprises two vertical frame supports 6 which are placed on the floor 1 and held on the rear wall 2 by means of suitable anchors 7. In the embodiment shown in Figures 1 to 3, a carriage 8 is guided vertically displaceably in each frame support. Between carriages 8 of adjacent frame supports 6, two platforms 9 and 10 arranged one above the other are rotatably mounted at a distance from one another about a horizontal axis of rotation connecting the two frame supports 6. The carriage 8 essentially has the task of fixing the vertical distance between the ends of the platforms adjacent to the rear wall and guiding the platforms along the frame supports 6.

The platforms themselves have reinforcement profiles 11 on their side edges, which at the same time form a lateral boundary of the platforms.

At the upper end of the frame support 6, a structural unit 12 is pivotally mounted about a horizontal axis of rotation connecting the two frame supports, which consists of two arms 13 and a crossbar 14 extending along the axis of rotation and rigidly connecting the arms to one another. The arms 13 extend in a vertical plane running above the side edges of the platform and have a length which is below half the length of the platforms. The assembly 12 consisting of arms 13 and traverse 14 is resistant to bending and torsion formed, ie this unit is very strong, so that a rigid component is formed.

On the underside of each arm 13, a piston rod 15 of a hydraulic piston-cylinder unit 16 rotatably engages, which is rotatably held on a tab 17 of the adjacent frame support 6. When extending and inserting the piston rod 15, the arms 13 are thereby pivoted about the axis of rotation, this pivoting movement taking place uniformly in both arms 13 due to the bending and torsional rigidity of the structural unit 12.

At the free ends 18 of the arms 13, a traction cable 19 is attached, the other end of which is held laterally on the reinforcement profiles 11 of the upper platform 9. The attachment points are chosen so that the traction cable 19 runs obliquely downwards from the free end of the arm to the upper platform. At the point of attachment of the traction cable to the upper platform, a further traction cable 20 is held, the other end of which is attached to the reinforcement profile of the lower platform in such a way that the lower platform runs essentially parallel to the upper platform.

Between the free end 18 and the axis of rotation of the arms, a pull rod 21 is rotatably articulated, the other end also rotatably engages the reinforcing profile of the upper platform 9, namely between the loading Fixing point of the pull cable 19 and the storage on the slide 8. In this way, the upper platform hangs on the pull cable 19 and the pull rod 21 stably on the arms 13. The lower platform hangs on the pull cable 20 and the slide 8 on the upper platform, whereby the pull rope 20 and the slide 8 act as parallelogram links.

If the arms 13 are pivoted by means of the piston-cylinder units 16, the upper platform and the lower platform attached to it can be raised (Figure 2) or lowered (Figure 3) as desired, the lower platform being aligned with the access in the raised state, in the lowered state Condition the top. The fact that the pull cable 19 and the pull rod 21 are attached to the arm at different distances from the axis of rotation of the arms 13 results in addition to the vertical movement of the platforms and a pivoting of the platforms, so that the platforms with their free ends in the raised state are raised, while in the lowered state they run essentially parallel (Figures 2 and 3). If such additional pivoting is not desired, the pull cable 19 and the pull rod 21 can be stored at one point on the arm 13.

The arrangement shown in Figures 1 to 3 allows the use of platforms that have one or more parking spaces next to each other, with the overall construction - apart from the width of the platforms and the width of the crossbar connecting the two arms - does not change.

The parking device shown in Figures 4 and 5 is constructed similarly to that of Figures 1 to 3, the same parts therefore have the same reference numerals.

In contrast to the exemplary embodiment in FIGS. 1 to 3, the platforms 9 and 10 in this exemplary embodiment are rotatably mounted on the frame supports 6 about stationary horizontal axes of rotation 22 and 23. Furthermore, the pull rod 21 is omitted.

In the lowered position, the platforms in this embodiment are inclined downwards, in the raised position upwards. The floor is also inclined in accordance with the inclination of the lower platform in the lowered position, the approach end being shaped horizontally. For this purpose, the approach-side part of the lower platform can be pivoted upwards relative to the rest of the platform, so that this part rests on the horizontal base piece 25 when the platforms are in the lowered position.

In the exemplary embodiments shown, the frame support 6 is supported on the floor and held on the rear wall of the building via anchors 7. It would also be possible to connect the frame support 6 with a horizontal, forward-reaching foot, so that the frame support with this foot and the platforms mounted on the frame support can be used as an independent unit without a load-bearing connection to the building. It would suffice to place this independent unit in a prepared building without the need for any special fixing work.
