Description

System for receiving, temporarily storing and dispensing movable objects

The invention relates to a system for receiving, temporarily storing and dispensing movable objects, in particular unmanned, movable motor vehicles, each of which takes over from at least one entry platform by means of a translating device of a tender rotatably mounted about a central axis and provided with at least one support arm ¬ men and placed on a free of a plurality of platforms or picked up again by this and transferred to an Aus¬ platform, the platforms are arranged along a helical travel rail for the tender next to each other in the radial direction.

In buildings which are intended to accommodate a large number of motor vehicles, in particular passenger vehicles, such as. B. in multi-storey car parks and large garages, there is a need to accommodate as many vehicles as possible on the space available. If the parking spaces and the access roads are laid out in such a way that each parking space can be approached individually, a large part of the total area remains unused because an area of approximately the same size is once again used for the area occupied by a parking space Access and add the space for maneuvering. Half of the available area thus remains unused.

In order to save space, devices have already been implemented in which the vehicles are parked on movable parking spaces in the manner of a paternoster elevator or a horizontally arranged conveyor belt, only one of the numerous parking spaces in front of the entrances and Exit is brought. Such a system requires elaborate drive mechanisms with which each entry and exit gear of a vehicle all the parking spaces with the vehicles on it must be moved.

A system which is also known is less complex, in which the parking spaces are arranged firmly next to and / or one above the other and one or more transport platforms are provided which accommodate the vehicle and bring it up to a parking space to which it is then transferred. To drive out, the vehicle is brought to the exit with the transport platform. In this case, the drive of the vehicle must be transferred from the transport platform to the parking space by the driver.

In a mechanical parking facility of the generic type, the parking spaces are arranged along a helix in the radial direction. In the remaining cylindrical cavity, a transport device called a tender travels on a rail which is also bent according to a helical line, at least one tender arm being provided which is supported on the rail by means of two running wheels. A motor vehicle to be parked can be transported upwards or downwards on the arm by rotating the tender about its own axis for the lifting or lowering process, so that by means of the arm a motor vehicle is moved from an entry platform to a free parking space or can be moved from this to an exit platform.

The invention is based on the object of developing a generic system in such a way that the implementation of motor vehicles with braked front and / or rear wheels is carried out fully automatically, so that there is no longer a driver in the vehicle for this purpose. Furthermore, with regard to its operational safety, stability and wear resistance, especially in winter, the system should to a high degree meet the harsh operating conditions that occur in everyday life. This object is achieved by the features specified in claim 1.

By means of the translating device according to the invention, it is now possible to pick up the vehicle parked on an entry platform, to move it onto the tender arm and to transport it in front of a platform of a parking box by means of the tender arm, which moves up or down along the helically curved rail to place it on the platform of the parking box or, conversely, when picking up a parked vehicle, to pull it from the parking space onto the tender arm and transfer it to an exit platform from where it can be driven away by the driver.

The translation device advantageously has a frame device which can be moved in the longitudinal direction between the wheels of the vehicle standing on a platform and on which at least four support arms projecting at right angles into the area of the vehicle wheels are arranged. At least two of these support arms can be pivoted according to the invention from a position directed in the direction of the frame device into the position protruding at right angles, in which they bear under pressure on the lower region of the respective vehicle wheel and lift it off the standing surface. Essentially, the frame device is formed by two longitudinal beams extending in the longitudinal direction of the tender arm, which are connected to one another by cross beams in the area of the inner end facing the tender center axis and the outer end facing the tender support arm. While four associated support arms are provided for the front wheels of a motor vehicle, of which the two support arms pointing to the tender axis are arranged rigidly in the region of the inner ends on the longitudinal beams and the two other support arms can advantageously be pivoted against the rear of the front wheels in order to press and lift them against the rigidly raised support arms are the two rear wheels of the motor vehicle assigned only two support arms arranged diametrically to the wheel axis of the vehicle. The design of the device by means of the four front support arms described above is expedient and sufficient for the case in which the rear wheels of the motor vehicle can roll on corresponding treads of the tender arm or on the parking space floors. This means that the rear wheels of the motor vehicle to be moved are not braked. In the case, however, in which the rear wheels are braked, this z. B. in connection with automatic transmissions and anti-theft devices, the device according to the invention is equipped with two further pivotable support arms assigned to the rear wheels of the vehicle, one against the front of a rear wheel and the other against the rear the other rear wheel is pivotable. In this way, the translation device advantageously detects and jacks up all four wheels of the vehicle, so that the vehicle is transported into or out of the box in a piggyback process, so to speak.

In order to be able to adapt the translating device according to the invention to different wheelbases, it is advantageously provided that the distance between the rear arms assigned to the vehicle and the front wheels of the vehicle is adjustable, this setting being mechanical using a screw spindle or hydraulic can be done with the aid of a piston / cylinder arrangement or an electric motor with a toothed rack. By arranging a pivotable support arm in front of the one rear wheel and the other pivotable support arm behind the other rear wheel, the horizontal forces which arise when the support arms strike the rear wheel tires cancel each other out. Compared to a system in which, for example, both support arms would strike the front sides of the rear wheel tires, this system has the advantage that the danger is avoided that the two front wheels are pulled out of their supports by the horizontal forces. To reduce the frictional forces between the support arms and vehicle wheels, freely rotatably mounted rollers are provided on the support arms in the region of the longitudinal sides coming into contact with the vehicle wheels. The frame device itself can be moved with rollers on the top of two raceways running along the edge in the longitudinal direction of the tender arm up to a corresponding platform. It is also provided that the raceways have lateral upstands, against which the support arms, which are supported on the top of the raceways by means of rollers, run by means of guide rollers which can be rotated about a vertical axis. In this way, the translating device according to the invention is guided in its longitudinal movement between the lateral edges of the raceways.

The tender advantageously has four tender arms, each of which is equipped with a transport device, for example a toothed belt drive, for driving the frame device of the translation device. Of course, other drive systems can also be used, such as a chain drive or hydraulic drive. The toothed belt drive can have an endless toothed belt which is guided over a horizontal toothed pulley mounted on the inner or outer end of the tender support arm. The vertical arrangement of the toothed belt ensures that no dirt can accumulate on your toothed belt, which could possibly lead to premature destruction of the drive device. The translating device is advantageously connected at its rear end to the toothed belt, for example by means of clamp connectors, and depending on the direction of rotation of the toothed pulley, can thus be cantilevered from the tender arm into a parking box or withdrawn from the parking box again onto the tender arm. When picking up a parked motor vehicle from a parking box, the translating device can be moved from the tender arm in the direction of the parking box until the two rigid support arms are approximately at the level of the front wheels of the car parked on the entry platform stand. Up to this position, the two pivotable support arms are still in the rest position, ie they are parallel to the two longitudinal beams of the frame device of the translation device. This allows them to be pushed between the two front wheels. As soon as the rigid support arms are in their end position and the translation device stops, the two pivotable support arms are advantageously pivoted through 90 ° into a position parallel to the respective rigid support arm by means of two hydraulic presses. In the final phase of the pivoting movement, the pivotable support arm rests against the rear of the tire of the front wheel and presses the front wheel upwards to the parallel end position during the remaining movement. As a result, the two front wheels stand out from the floor of the parking space.

A drawbar is preferably arranged between the transmission device and the toothed belt, through which the vehicle can be pushed further outward in the radial direction. If the vehicle is pushed further out in the entry or exit box for people getting in and out than in the parking boxes, there is a greater lateral distance on the vehicle from the adjacent boxes. This enables the occupants of the vehicle to get in and out comfortably without the opened doors being restricted by the adjacent walls.

In order to secure the drawbar against twisting and / or torsion when the transfer device is moved, the drawbar is preferably formed from a torsionally stable square spar and has a guide device accommodated between sliding elements. The transfer device can be guided on the side upturns of a parking space according to a certain run-in area of guide rollers which are attached to the support arms. In order to obtain the highest possible degree of volume filling of the system, the individual parking spaces overlap in their radially inner area, so that due to the limited space there is no lateral opening. lines are available at the parking spaces and therefore no guidance of the translation device by the guide rollers on the support arms is possible. In this area, the tiller guide ensures safe and precise guidance of the transfer device.

The two longitudinal beams of the translating device are advantageously arranged within the track width of the load-transmitting rollers and not approximately in the track width of the load-transmitting wheels. In this way, a low design of the translation device can be achieved and a very simple construction, since the loads are introduced directly from the rollers of the support arms into the running surface and the translation device i.w. only has to absorb and derive their own weight.

One advantage of the four-wheel translating device is, inter alia, that the loads from the weight of the motor vehicle, regardless of the track width of the motor vehicle, are always in the track width of the rollers arranged on the six support arms of the translating device on the platform or the raceways be transmitted. In an embodiment of the transmission device in which the motor vehicle rolls on the two rear wheels and is only jacked up with the front wheels, the location of the load introduction depends on the different track gauges of the motor vehicle.

The pivotable support arms assigned to the rear wheels of a power vehicle are advantageously mounted on a slide, which in turn is guided on the longitudinal beams by means of bearings. By means of this slide and a suitable drive, the distance between the front and rear support arms can be changed so that the transmission device can be adapted to different wheelbases of different motor vehicles. The bearings with which the slide is guided on the longitudinal beams are advantageously PTFE plain bearings. In addition, the sled has on his both longitudinal sides of the rollers with which it is supported in its rest position after the support arms have been pivoted in on the raceways of the tender arm or the platform.

So that the support arms are guided without contact when swiveling back into their rest positions running in the longitudinal direction of the side members relative to the raceways of the tender arm or the surface of the platform, it is advantageous if they are raised along an inclined plane when swiveling in the longitudinal direction of the side members become.

The tender arms can be aligned by means of a corresponding rotational movement of the tender relative to the platforms which are arranged next to one another and in the radial direction around the tender. In this case, one or more entry or exit platforms can be provided in addition to parking box platforms which have the same structure as one another. In this case, it is advantageously provided that each platform is formed by a sheet metal which extends over a maximum vehicle length and has at least lateral upturns which rests on a frame substructure. This frame substructure has at least two longitudinal girders which take up the individual loads which can be moved and which are in turn supported on at least two cross girders which transmit the loads in building supports. The inner platform end (pointing towards the tender axis) can be supported on consoles of the tender travel rail via a cross member.

The sheet is advantageously produced from wear-resistant material which is corrosion-resistant to de-icing salt solutions, in particular from ferritic, chromium-alloyed steel. This material has a high wear resistance, is corrosion-inhibiting, in particular also resistant to weak salt solutions and at the same time has a high wear resistance due to the low nickel content. The steel has a significantly lower level than that of austenitic steels Coefficient of thermal expansion, so that the high heat distortion occurring when welding austenitic steels is not to be expected. The price is also around 50% of the price of austenitic chromium-nickel steels. A ferritic chromium alloyed steel with 10.5-12.5% Cr with only 0.3-1.0% Ni is preferred.

In addition to its covering function, the sheet also has to perform certain carrying functions.

It takes up the weight of the translating device, which is transferred to the unstiffened part of the cover plate via the rollers arranged on the two longitudinal beams of the translating device. Furthermore, the horizontal forces generated by braking or starting the tender on the support brackets of the tender rail are transmitted into the platform which projects outwards towards the inside of the building and which must be diverted into the supports via the cover plate acting as a shear field. Finally, because of the different track gauges of the parked motor vehicles, the rear and front wheels of the motor vehicle can lie to the side of the two platform longitudinal members that emerge. In order to avoid local stiffening of the cover plate in this area, a finite element analysis was carried out to show that a 4 mm thick plate can absorb these car wheel loads through plate and mainly membrane action. In order to absorb the normal forces from the membrane effect, rigid edge supports have to be created on the two longitudinal edges of the floor panel by means of an upturn. These upturns are advantageously required at the same time in order to prevent the water running off the motor vehicles from running off to the side.

According to a further advantageous feature of the invention, the sheet is held on the longitudinal or cross members only by clamping forces. Furthermore, an impact-absorbing is advantageously between the sheet and the substructure Ending layer of wear-resistant elastic material in particular rubber provided. This layer prevents direct contact between the cover plate and the longitudinal or cross members. The arranged above the side members elastic material, the z. B. can be formed in the form of gui strips, improves the load transmission from the rollers of the pivotable support arms of the translation device and prevents possible wear by relative movement of the sheet metal relative to the side members.

To fix the front wheels of a motor vehicle, flat irons can be attached to the upper side, in particular screwed on, in order to avoid a weld that could possibly lead to twisting. The clamps for fastening the sheet metal to the supports and the flat iron for the front wheels are screwed onto threaded bolts that are open. Through the use of screwed-on threaded bolts, through holes are avoided, through which water could possibly drip onto the cars parked underneath.

All platforms are advantageously inclined by approximately 2% towards the outside of the building. Because of this gradient, dripping water can be discharged to the outside and drips off to an annular channel of the building floor. Because of the only corrosion-inhibiting effect of the material used, it must be avoided that water containing de-icing salt can remain on the surface of the floor panel for a long time.

Since the tender arms are only temporarily assigned to certain platforms, it must be provided that on the inside at least the entry and exit platforms or platforms, fold-away personal protection devices are provided which close the platform area from the tender area, as long as there are people in the platform area. Otherwise, the parking box platforms are such Do not protect the facility as there are no people in the parking area.

It should be borne in mind that in all mechanical parking systems the access time or the hourly capacity of the transport system is the decisive factor for the economy and the acceptance of the parking system. In multi-storey car parks with linear parking systems, in which the horizontal and vertical movements take place in succession, the access time is very long, so that the conveying capacity is low. In contrast, in a parking garage equipped with the parking system according to the invention, the access time can be reduced considerably to two minutes per vehicle. Here the lifting or lowering movement and the rotating movement of the tender can be carried out simultaneously. Such short access times can only be achieved by connecting different transport processes in parallel and by high transport speeds on the tender or when transporting with the transfer device.

In order to achieve an optimal conveying capacity of the transport system, it is advantageously provided that the tender has four support arms offset at an angle of 90 ° and that four entry platforms are each assigned to the tender arms crosswise. The full transport capacity of the four-armed tender can only be used sufficiently if the insertion of the vehicles from the entry platforms onto the four tender arms can take place simultaneously and, if possible, the subsequent transfer from the tender arm to the parking space takes place simultaneously. Because of the 90 ° offset arrangement of the tender arms, this also means a corresponding 90 ° offset arrangement of the entry platforms and z. B. an arrangement of the exit platforms offset by 45 ° relative to the entry boxes. If possible, the motor vehicles are parked on the individual floors of the parking system in parking spaces offset by 90 °. After some time due to the random parking of the vehicle If this 90 ° arrangement of free parking spaces is lost on the individual floors, at least two free parking spaces offset by 90 ° must be selected using a computer program so that at least two parking processes can take place simultaneously.

If, for reasons of space, the above-described crosswise arrangement of the entry or exit platforms is not possible, at least three adjacent entry platforms are advantageously combined with three exit platforms which are each offset by 90 ° to the entry platform.

The tender then picks up only three vehicles from their parking spaces, thus leaving one arm free. This free arm is moved in front of an entry platform, the second tender arm, which is offset by 90 °, then stands in front of an exit platform. This means that a vehicle can be pushed onto the free tender arm at the same time as another vehicle is pushed from the loaded tender arm into the extension platform. The tender then moves through an angle of 90 ° ± dz so that a vehicle can be loaded onto the newly cleared tender arm at the entry platform and at the same time a vehicle is pushed from the next loaded tender arm onto the next exit platform can be.

Advantageously, the shifting speed of the translation device can be controlled in such a way that an unloaded translation device can be moved faster than a loaded translation device. Since the extension of the rear part of the transfer device for jacking up the rear wheels of a motor vehicle is a time-consuming process, which can always be omitted if the rear wheels are not braked, the driver is asked in all cases when parking to release the handbrake. Only in vehicles with an automatic transmission can the blocking of the rear wheels not be released during parking. In order to check whether the rear wheels are blocked in a vehicle standing on an entry platform, it is advantageously provided that the extension of the slide part of the transmission device and the pivoting out of the support arms for the rear wheels of a vehicle depending on one predetermined limit value exceeding current consumption of the drive motor of the toothed belt drive of the transfer device takes place. The procedure is as follows:

With the two pairs of support arms, the translating device comprises the two front wheels of the vehicle and lifts the two front wheels while the support arms are being pivoted out. The translating device then moves in the direction of the tender arm. The current consumption of the drive motor is measured here, since it is a measure of the determined driving resistance. Since the rolling resistance number for a car tire is only approx. 1.5% of the tire load compared to approx. 50% of the tire load for sliding friction when grinding the blocked rear wheels on the surface, the resistance to displacement of the lightest vehicle with braked rear wheels is that is significantly higher than that of the heaviest possible vehicle with free-running rear wheels. Regardless of the vehicle weight, it can therefore be determined from the current consumption of the drive motor of the booster whether the rear wheels are blocked or not. Only in the relatively rare cases of blocked rear wheels is the rear part of the translation device extended. This measure advantageously makes it possible to almost double the delivery rate per hour.

In an advantageous embodiment of the invention, means are provided which secure the position of the motor vehicle on the tender or the translation device against displacement. This prevents the motor vehicle mounted on the tender from centrifugal forces during rotation the tender can jump out of the holder of the translator. This is particularly problematic if the wheels are only picked up between the two front swivel arms and the vehicle is not held by the rear arms. It must also be taken into account that the centrifugal force is linearly dependent on the mass of the vehicle and quadratically on the speed of the vehicle's center of gravity. In large vehicles with a fully loaded trunk, the center of gravity moves radially outwards in the area of higher rotational speeds. The centrifugal forces that occur can preferably be absorbed by two devices. The first device is located at the point where the front tires rest on the front support arms of the translation device and the second device is located behind the rear bumper. Since the bumper can only absorb limited forces, a distribution of the centrifugal force between the front and rear device can be achieved using the spring action of the vehicle tires.

The device arranged on the rear bumper is preferably provided for the special case in which the toothed rivet, which holds the translation device in the radial direction, tears. The centrifugal force can then only be absorbed via the barrier on the rear bumper. Damage to the bumper can occur under these circumstances, but damage to the entire vehicle by moving the tender is avoided.

Basically, the safe reception of the vehicle on the tender must be ensured when rotating the tender. A safety factor must also be taken into account in the event that, for example, the trunk is loaded, the front axle is relieved and the holding forces on the front swivel arms are thus reduced.

The said means preferably have at least one pivotable bracket on the radially outer side one wheel of the two front wheels of the motor vehicle. This bracket can be arranged on the tender arm or on the two front swivel arms. The motorized pivoting of the bracket on the wheel of the motor vehicle secures the motor vehicle on the tender against displacement as a result of centrifugal forces. The swivel drive motor can be controlled in such a way that it switches off against the tire when the pre-adjustable contact pressure of the bracket is reached. Furthermore, it is alternatively possible in each case to provide a lever on the swiveling arms of the transmission device which engage on the rear side of the front wheels and which secures the vehicle against displacement due to centrifugal forces. The lever can be sprung short and hard in order to be able to compensate for size differences of the tire diameter in different vehicle types.

In an advantageous embodiment, the securing means have a flap on the translating device which can be folded against the rear of the vehicle against its bumper in order to secure the position of the motor vehicle on the translating device.

The system shown in FIG. 1 forms an underground parking garage, the basic structure of which is designed as a hollow cylinder. In the above-ground part there is the entrance at 1 and the exit at 2. In the interior of the hollow cylinder, a large number of parking spaces 3 are accommodated, which are oriented radially with their longitudinal extension and adjoin the inner wall of the hollow cylinder with their radially outer ends. The parking spaces 3 are arranged along a helical line, so that they lie side by side without interruption from the first to the last or from the top to the bottom parking space. On their radially inner side, they are connected to one another by a rail 4, which accordingly also runs in a helical shape.

In the cylindrical interior space not occupied by the parking spaces 3 there is a so-called tender 5 with four support arms 6. Each of the support arms of the tender is supported on the rail 4 by two respective running wheels 7. Four motor vehicles 8 to be parked can be transported upwards or downwards together on the four arms of the tender 5. The tender 5 rotates about its own axis during the lifting or lowering process, so that each of the four arms can move to a free parking space or an entry or exit platform. The translating device 9 according to the invention essentially has a frame device 12 which can be moved in the longitudinal direction between the front wheels 10 and the rear wheels 11 of a motor vehicle 8 and on which four support arms 13, 14 projecting at right angles into the area of the front wheels 10 for the front wheels 10 and Support arms 15, 16 are provided for the rear wheels 11.

The frame device 12 has two longitudinal beams 17 which extend in the longitudinal direction of the tender arm 6 and which are connected to one another by cross beams 18, 19 in the region of their inner end facing the tender central axis and the outer end facing the tender carrying arm end. The side members are z. B. 5.60 m long and consist of RRO profiles. The inner cross member 18 pointing towards the center axis of the tender is widened by a sheet 20 placed on the top and bottom of the longitudinal members. The outer cross member 19 lying in the direction of the tender arm consists of a transverse rectangular tube. The support arms 13 are rigidly mounted on the inner end of the frame device 12, while the support arms 14 can be rotated through 90 ° in a horizontal plane about a pivot point 21 by means of two hydraulic pistons. The support arms are provided with rollers 22 approximately in the middle of their longitudinal extent, by means of which the support arm can be supported on the running surface of the tender arm 6.

There are also attached to the outer ends of the support arms 13, 14, 15, 16 guide rollers 24, by means of which the vehicle 8 is laterally guided on edges 25 of the running surface 23 or 26 of a parking space 3 (see FIGS. 7 and 8).

The rear support arms 15, 16 are pivotally mounted on a carriage 27, which in turn is supported by means of PTFE plain bearings 28 (see FIGS. 5 and 6) on the side members 17 in the vertical direction and by means of support rollers 29 in the horizontal direction Side members 17 supports. The side members and the slide are made with the help of wheels 30 can be moved on the running surface 23 when the slide is not loaded and the support arms 15 and 16 are pivoted in. The pivoting movement of the support arms can take place with the aid of hydraulic cylinders 31. When swiveling in, the respective support arm 14, 15, 16 is moved along an inclined plane, so that the roller 32 is lifted off the running surface 23.

The distance between the front support arms 13, 14 and the rear support arms 15, 16 is adjusted by adjusting the slide in the direction of arrow 33 with the aid of the hydraulic cylinder 34.

A transport device, in particular a toothed belt drive 35, is provided on each of the four tender arms 6 for the longitudinal movement of the frame device 12. The toothed belt drive 35 has an endless toothed belt 36 which is guided over a horizontal toothed pulley 37, 38 mounted on the inner and outer ends of the tender support arm 6. The translating device is connected to the inner end via a clamping connector 39 with the toothed belt 36 and can thus be pushed into a parking box, depending on the direction of rotation of the driven toothed pulleys 37, 38, or can be pulled back out of the parking box onto the tender arm . When a parked motor vehicle 8 is picked up from a parking box 3, the translating device 9 is displaced from the tender arm 6 in the direction of the parking box until the two rigid support arms 13 are approximately at the level of the front edge of the front wheels 10. The two pivotable support arms 14 are still in their rest position up to this position, i. H. they are parallel to the two longitudinal beams 17. This allows them to be pushed between the two front wheels 10.

As soon as the rigid support arms 13 are in their end position and the translation device 9 stops, the two pivotable support arms 14 are pivoted through the hydraulic cylinders 31 by 90 ° into a position parallel to the rigid support arms 13. In the final phase of the swivel movement, the lie down Swivel arms 14 on the rear of the front wheels 10 and press the front wheels upwards during the remaining pivoting up to the parallel end position. As a result, the two front wheels 10 stand out from the floor panel of the parking box 3.

The translating device 9 is now retracted again via the toothed belt drive 35 in the direction of the center of the tender, thus dragging the car rolling on its two rear wheels 11 onto the tender arm. In this position, the tender 5 or the relevant tender arm 6 is now moved to the exit platform, the translating device 9 then shifts the motor vehicle 8 on its two rolling rear wheels 11, so to speak, in the reverse direction of travel into the exit box. The two swivel arms 14 are pivoted back into their rest position parallel to the longitudinal beams 17 of the frame device 12, as a result of which the two front wheels 10 lower onto the footprint of the exit box. The translating device 9 can then be pulled back onto the tender arm.

If the vehicle is to be piggybacked from an entry box into a parking box, the rear pivotable support arms 15, 16, which are pivotably mounted on the carriage 27, are also used. The hydraulic cylinder 34 arranged between the two longitudinal beams 17 pushes the slide 27 up to the height of the two rear wheels 11 of the car, where the slide feed is stopped in a sensor-controlled manner.

Then the two pivotable support arms 15, 16 arranged on the right and left on the displaceable carriage 27 are pivoted out in the opposite direction of rotation by 90 °. The support arm 15 lie against the front of the rear wheel 11 and the support arm 16 against the rear of the corresponding other rear wheel 11. Depending on the distance between the two pivotable support arm longitudinal axes and the diameter of the rear wheel of the car, the two rear wheels are in the final phase the pivoting movement more or less strongly raised. By arranging one pivotable support arm 15 in front of a rear wheel 11 and the other pivotable support arm 16 behind the other rear wheel 11, the horizontal forces which occur when the support arms strike the rear wheel tires cancel each other out.

7 and 8, a platform 40 of a parking space 3 is shown in a top and sectional view. The platform 40 has a sheet metal 41 which extends over a maximum vehicle length and has lateral upstands 26 which rests on a frame structure 42. The frame construction has two longitudinal beams 43 which take up the locally acting individual loads and which in turn are supported on at least two cross beams 44, 45 which transmit the loads in building supports 46. The inner platform end 47 is supported by a cross member 48 on brackets of the tender rail 4.

Flat irons 49 are attached, in particular screwed on, to fix the front wheels 10 of a vehicle 8 to the top of the sheet 41. These flat irons are arranged at an angle to the longitudinal axis of the platform 40, so that melt water collecting between the flat irons 49 can flow off to the outside of the platform, since the latter has a slope of about 2% from the inside to the outside. A gap 51 is provided between the building wall 49 and the outer platform end 50, through which the melt water can flow off. The lateral upstands 26 also prevent the water running off from the motor vehicles from flowing off laterally.

As an alternative to the arrangement of the transport device shown in FIG. 3, a drawbar 60 can be provided between the clamp connector 39 and the translating device according to FIGS. 9 and 10. The drawbar 60 extends the radius that can be reached with the transport device, the length of the Drawbar is preferably between 1 and 2m. The translation device (only partially shown) can be pushed outwards into the entry and exit boxes by the length of the drawbar. The maximum extended position of the drawbar 60 is shown in dashed lines.

The toothed belt 36 is guided in a toothed belt guide 52 in order to prevent the toothed belt 36 from tilting or swerving to the side.

A top view of the drawbar 60 is shown in FIG. 11. The drawbar 60 is screwed at one end to the cross member 18 and welded to it. At the other end of the drawbar 60, a clamp connector 39 is provided, which connects the drawbar 60 to the toothed belt 36.

FIG. 12 shows a side view of the drawbar 60 and part of the drawbar guide 61. The drawbar has a square hollow profile, to which a guide plate is welded, to which two plastic plates are screwed. The plastic plates of the drawbar guide 61 ensure low-friction sliding in the rails of the drawbar guide 61. The translator can also be moved exactly by the drawbar guide 61 in the starting area of the parking boxes, in which no side plates are provided for guiding the carriage into the parking boxes.

FIG. 13 shows an enlarged section of a front wheel 10 which is mounted on two support arms 13 and 14. In order to secure the front wheel 10 against displacement, a bracket 62 is arranged on the rear side thereof, which is pressed against the rear side of the front wheel 10. The bracket 62 is pivotally arranged on the tender arm. It is also possible to provide the bracket 62 on the translation device 5 itself.

14 shows a further possibility for securing a front wheel 10 mounted on two support arms. To do that To secure the front wheel against displacement, a swivel lever 67 is arranged on the rear side thereof, which is rotatably connected to the swivel arm 14.

The swivel lever 67 is mounted on the swivel arm axis 70 via a ball bearing. The pivot lever 67 has a tube 71, on one side of which the ends of a V-shaped nose are welded. When the swivel arm 14 of the translating device is pressed against the rear side of the front wheel, the swivel lever 67 rotates clockwise into an upright position. When the pivot lever 67 reaches its end position, the pivot lever 67 strikes against a stop 72 and the tire 10 is in a raised position 10 '. When the vehicle is to be put down again and the support arm 14 is pivoted back, the pivot lever 67 rotates back into its basic position due to the leg spring 68. When the basic position is reached, a stop 74 welded to the tube 71 abuts against an end piece 73 welded to the support arm 14.

15 to 17 a further embodiment for securing the vehicle on the tender is shown. A pivot barrier 75 is pivotally mounted on a carriage 76. The carriage 76 is slidable on two guide rods 81 in the longitudinal direction of the tender. The shifting takes place by means of a chain wheel attached to the tender arm, which meshes with a chain rack attached to the slide.

In a truss of the tender, a spline shaft 77 is rotatably mounted in two pillow block bearings. The pivoting barrier 75 is welded to a rectangular hollow profile 78. Two inserts are welded into the hollow profile 78, which form the counter profile to the spline shaft 77. The spline shaft 77 can be rotated by 90 ° via a linear drive 79 by means of a lever 80 arranged on the spline shaft 77. When the slide moves along the tender arm, the rectangular hollow profile 78 slides over the spline shaft 77. In one embodiment of the invention, the vehicle is secured by a pivot lever 67 on the front wheel and a pivot barrier 75 on the bumper. The pivoting barrier 75 must be displaceable for accommodating different types of vehicles. Furthermore, the bumpers can only absorb a limited force in the vehicle direction. Therefore, the centrifugal force acting on the vehicle is divided between the two holding devices. For this purpose, use is made of the fact that the tire has a certain elasticity. The pivoting barrier 75 initially remains in the rest position of the tender 1-2 cm behind the bumper of the motor vehicle. As soon as the tender turns and a centrifugal force acts on the vehicle, the flexibility of the front tires shifts the vehicle a little outwards, so that the pivoting barrier 75 now rests on the bumper of the motor vehicle. The proportion of the centrifugal force that is transmitted to the pivoting barrier 75 can be set by adjusting the distance between the bumper and the pivoting barrier 75. In addition, due to the arrangement of two devices for securing the vehicle on the tender, the system has advantageous redundancy.

An alternative possibility for securing the vehicle 8 is shown in FIG. 18. After the vehicle 8 has been picked up on the translation device 9, the translation device is rolled onto a tilting device 65 arranged on the tender 5. After the translation device 9 has reached its end position, the tilting device 65 is lowered towards the front of the motor vehicle by means of a lifting device 64, whereby the translation device 9 assumes an inclined position with the motor vehicle 8. The inclined position prevents the motor vehicle 8 from moving in the rearward direction relative to the translation device 9 as a result of centrifugal forces when the tender 5 is rotated. 19 shows a further possibility for securing a wheel of a motor vehicle 8. The wheel, in this case the rear wheel 11, is secured by means of a self-locking barrier 66. The barrier 66 is pivotally arranged on the tender 5. It is possible to lower the barrier 66 so that the front wheels can roll over the area with the barrier 66. If the vehicle 8 is rolled onto the translation device 9, the rear wheel 11 is rolled over the barrier 66, the barrier 66 being pivoted through 90 ° and the rear wheel 11 being secured against displacement. A torsion spring 69 is provided for the barrier 66, with which the barrier 66 is pretensioned, so that the barrier 66 is held securely in a position in which a vehicle can be accommodated.
