Description

The invention relates to a parking device for motor vehicles according to claim 1.

Shutters described in the introduction have been known for a long time. They are used, for example, in parking garages or underground garages to increase the available parking spaces for motor vehicles. By the known parking devices can on predetermined plans the Number of abzustellenden motor vehicles are significantly increased.

Known arrangements have, for example, a plurality of lifting drives in order to move the superposed platforms in each case. For a coordinated movement, in particular to rule out that set vehicles damage, a corresponding control is provided.

Since the platforms in the access area as well as in the area facing away from the access area, for example, are supported by corresponding Hubantriebe, the position of the platform is determined at any time exactly. However, this requires a considerable effort, since lifting devices are to be used, for example, at the front and rear ends of the platform. It should be noted that the lifting devices are anyway provided in the longitudinal direction twice to support the platforms left and right respectively. The publication DE 2301428 discloses a parking device for motor vehicles, having the features of the preamble of claim 1.

Based on this prior art, it has the object of the invention to provide a storage device, as described above, available, the cost, in particular implementation costs is lower.

To solve this problem, the invention first proposes that the platform in the respective position by a support and a stop on the stand can be fixed.

The platform rests in the respective position on a support, that is, the weight of the platform is absorbed by the support. As a rule, one degree of freedom remains upwards. Now, if the platform articulated, as is the case for example with the linear actuator, then a rocking effect may result, which is undesirable. However, it is provided that the platform in the respective position by a support and a stop on the stand is fixed, so the platform, especially in the traffic position, ie in the position in which a vehicle enters or exits, safely and reliably out.

By this solution according to the invention, it is possible that can be dispensed with a stand-alone lifting drive in the region of the stand. The lifting movement is then derived, for example, by suitably arranged tension elements from a central lifting drive. As a result, the cost of the storage device according to the invention is very low.

Furthermore, in the prior art parking devices are known, which, as described, are pronounced, and are already provided with a lifting drive, which cooperates with a tension element for raising and lowering the platform.

For such parking devices is proposed that a Zugelementlängenausgleich is used by which the length of the tension element, in particular during the lifting / lowering operation, is variable. On the known tension elements, the movement of the platforms is suitably controlled by the use of chain stoppers arranged on the tension element. If the chain stopper is located on a stop, the pulling length of the pulling element is shortened accordingly. It then follows that the (other, not used) tension element is stored under certain circumstances uncontrolled and interferes, for example, with other elements of the device disturbing, for example, such that the storage device is blocked. But if, according to the invention, it is proposed that a Zugelementlängenausgleich is used, so on the one hand, the reliability of the storage device according to the invention is significantly increased and saved on the other side otherwise necessary effort for protection against the undelayed tension elements. The so designed Shutdown thus contributes both to keep the implementation effort low, but also to minimize maintenance.

The proposed solution reaches surprising, since a relatively complicated, kinematic movement, namely first a pivoting movement of the platform, which is then followed by a lifting of the platform, with one and the same simple kinematic means, namely a lifting drive, which with a tension element for the lifting and lowering of the platform interacts. In this case, the lifting drive, for example, on one side of the parking device (or the platform) is provided and the tension element takes over the movement for the other end of the platform in a suitable manner. By this proposal according to the invention the initially stated object is achieved more than satisfactory. This solution provides a means by which it is also possible to realize relatively difficult trajectories of the platforms, so as to be able to use for example the storage devices for difficult applications, but without having to modify the storage device as a whole. It is completely sufficient to adjust with adjustment means, for example, the length of the tension element and the arrangement of chain stoppers on the tension element, for example, the kinematics of the storage device and thus to vary. Ultimately, this proposal greatly extends the variability of the entire invention, which will be discussed in detail below.

Furthermore, solutions are also proposed in which, for example, a coupling or the like is provided, whereby, for example, a mixing movement is possible between the pivoting movement and the longitudinal movement. The movement of the storage device is achieved by a suitably suitable control of the effective train lengths of the tension element.

In the context of the invention, of course, shutdown devices are included, which integrate several or all of the aforementioned solutions shown separately.

It is favorable that for each position, in which a platform is movable, also a support and a stop for fixing the platform is provided in this position. Therefore, for the lower position, a lower support and a lower stop and for the upper position, an upper support and an upper stopper is provided. In this context, it should be emphasized that the term "position" refers to the position of the platform with respect to the stand and not to the connection of the platform to the access. For example, in the lower position, a lower platform will not be near the driveway, but the upper platform above it will be passable in the lower position, for example. Then moves the storage device such that the upper platform runs in an upper position, the lower platform gets to the driveway and can be entered or driven accordingly.

In particular, it has been found in a variant that it is favorable that a determination of a first, for example, the upper platform by the second, for example underlying platform takes place. In a simple embodiment of the storage device, for example, only two platforms are arranged one above the other. These two platforms are connected on the one hand by the stand or corresponding guide elements on the stand and on the other hand by the lifting drive with each other, wherein the respective connection points are articulated. The resulting body can be understood as a crooked rhombus, the opposite sides are not exactly parallel. The geometric relationships are correspondingly complex. It is important, however, that the lower platform articulated mechanically with the upper Platform is connected. This configuration therefore makes it possible to determine by fixing the first, for example, upper platform, the lower platform, for example, if just the lower platform for loading or unloading, ie the retraction or extension of a vehicle is set accordingly. This is a significant advantage, since the cost of designing the stops and supports can be reduced accordingly. Finally, a stop-pad pair is used in the respective position to auszusteifen the entire articulated arrangement of the two platforms for parking and parking the vehicles or for loading and unloading with other goods accordingly and set, for example, on the stand.

In a variant, it is proposed that a stop and a support, at least during operation of the storage device is fixedly arranged on the stand. Thus, a stationary stop or a stationary support on the storage device is defined, which defines, for example, corresponding end positions of the storage device by design. As a stand in the context of the invention, both a solution that absorbs the weight of the platform, possibly with a vehicle, as well as a solution in which a separate stand is used, which does not or only partially the weight is used. This stand may be supported on the floor or on the wall.

In this case, however, it reserves the option of designing the support arranged on the stand or the stop in the respective position on the stand to be variable in a further variant. This can be realized for example by a corresponding screw fastening. The effect of this relatively simple measure is considerable. By simply moving the support or stop the position is changed. The measure So it is suitable to adjust the position of the platform in the storage device accordingly.

This preference allows, for example, the parking on site, to adjust exactly during assembly.

In addition to this first group of respect to the movement of the platform fixed stop or the edition but also a second variant is proposed. The variant provides that with respect to the stand, a longitudinally movable stop or a support is provided. This longitudinally movable stop or this edition allows namely during the movement of the platform according supportive and leader to act, namely, it is only on reaching the respective position, for example, the lower or upper position, it is important that stop and support the Define platform accordingly.

It remains open whether the stop and the support are each fixed, each movable or, for example, a movable stop with a fixed support or vice versa a movable support is combined with a fixed stop.

In this context, the storage device also includes supports and stops that can be activated if necessary, so for example, in the respective trajectory of the platform can be pivoted. Such embodiments are also part of the inventive idea.

Cleverly, a longitudinally movable stop or a longitudinally movable support is arranged directly in the manner on one of the platforms.

In a preferred variant of the invention, it is proposed here that the storage device has a lifting bar and the lifting bar has a support and a stop.

The lifting bar is designed for example as a threaded rod and support and stop are adjustable by appropriate nuts on the threaded rod and fixed.

Hereby, another possibility is suggested to make the position of the platforms mutually adjustable. With skillful choice while the position of the upper platform, regardless of the position of the lower platform can be influenced accordingly.

It is possible, for example, to adjust the respective angular position of the platforms when entering and leaving the parking space by the respective position of the stop either on the stand or on the lifting bar. Thus, the storage device additionally achieves the advantage that it is extremely flexible in its field of application, since these are adaptable in a simple manner for various installation arrangements. Ultimately, only the respective stops must be moved to achieve the desired entry and exit conditions. The adjustment effort is minimal, the effect considerably, since a high variety of types is achieved with this shutdown device according to the invention.

In a preferred embodiment, it is provided that the lifting bar with the movement of the platform can be raised and lowered. Conveniently, therefore, the lifting bar is hinged to the platform, preferably connected to the lower platform. In this context, the lower platform is understood to be the platform that is located directly below the upper platform.

Conveniently, a driver is hingedly connected to the platform and the driver cooperates with the support or the stop of the lifting bar. The driver counts as part of the platform. In a preferred embodiment, the platform is not directly but indirectly fixed by a driver or other element by the support and a stop. It is of course equivalent within the meaning of the invention, whether now interacts with the support of the platform and the stop on the platform directly with this.

Furthermore, it is not limited to that the driver cooperates only with the support or only with the stop of the lifting bar. Of course, it is possible that the driver interacts with both elements. Preferably, in this case, the upper platform is equipped with a driver, in particular when the lifting bar is attached to the arranged directly below the upper platform lower platform. Since on the one hand the lifting bar is pivotally connected to the lower platform and on the other hand, the driver cooperating with the lifting rod is pivotally connected to the upper platform, this results in an articulated in its vertices C, which is determined and stiffened accordingly by the inventive use of support and stop becomes. Furthermore, both arrangements in which only one stand is used, but usually is the platform, possibly also for several parking spaces, side by side between two uprights, which are each arranged laterally, are included.

Conveniently, a lifting drive is provided for the platforms. As a rule, a storage device has two with respect to the longitudinal axis at the same location located lifting drives, the left and right of the platform are arranged. The lifting drives are designed, for example, as hydraulic cylinders or as electric motors or the like. In this case, the lifting drive is pivotally connected to the platforms, whereby a corresponding antiparallel movement of the platforms is possible.

Similarly, it is also envisaged that the platforms are guided in articulated mounted in the stand movable carriage. The two carriages are independent of each other, the lifting bar connects, for example, the two carriages or the two platforms.

In a preferred variant of the invention it is provided that a tension element is provided for the platform. Preferably, the invention is realized with a linear actuator or with lifting drives on one side of the storage device (or platform). The saving of linear actuators the total cost of the storage device according to the invention is reduced accordingly. But in order to reliably move the platform, which has a corresponding length (yes, it must be a vehicle parked on it), should ultimately be provided at the respective platform ends an arrangement that impresses the lifting or lowering movement in the platform. Cleverly this is a tension element is used, which is able to interact in a suitable manner with the lifting drive and thus corresponding lifting and lowering movements also at the platform end to which no lifting drive is arranged reached.

In principle, it is also possible to arrange both in the front and in the rear platform area depending on a corresponding tension element, which interact with the lifting drive, which is located for example in the center of the platform. In this case, the tension element is deflected with corresponding deflection rollers in a suitable manner.

Conveniently, a pulley-like tension element is provided for the platform. A flaschenzugartiges element is particularly characterized in that a fixed and a movable guide roller is provided, via which the tension element, for example, a rope or chain or the like is performed.

In a preferred variant of the invention it is proposed that the length of the tension element, at least in sections, results from the position of the lifting drive.

As described above, the invention also includes a solution in which a Zugelementlängenausgleich is provided, through which the length of the tension element is variable. Overall, the total length of the tension element, at least in sections, is determined by the position of the lifting drive by the proposal according to the invention. The total length of the tension element is defined by the length along the tension element, which results between the two end points of the tension element. This length is usually larger, at best the same size as the tensile length of the tension element. The tensile length is defined by the position of the chainstopper on the tension member to one end (e.g., the fixed end) of the tension member.

At the beginning of the lifting movement (provided that the storage device is in the lower position), the lifting drive will act only on one side of the platform, as far as the lifting drive interacts with the tension element, the force applied there is used to increase the length of the tension element by the tension element length compensation lengthens. This results in a change in the length of the tension element depending on the position, ie the position of the lifting drive. However, this relationship does not necessarily have to be for the entire stroke range of the lowering device be, by suitable subdivision, the most diverse kinematics can be achieved.

Cleverly, a chain stopper is used on the tension element, which cooperates in a suitable manner with a stopper stop on the device, preferably on the stand. As described, the train length of the tension element is adjusted by the chain stopper and, if the chain stopper abuts the stopper stop, the train length is also reduced accordingly.

The invention is, for example, be formed such that in a first variant, a large train length is divided by the chain stopper in a lower train length or the tension element is activated only when the chain stopper abuts the stopper stop and so defines the train length. Thus, the invention results in a broad spectrum of applications, which can be used in a suitable manner, in particular for the kinematics of the platforms to be moved. The variability of the invention is considerable.

Thus, it is provided, for example according to a development of the invention according to the invention, that changes the movement direction of the platform in the raising or lowering movement by the concerns of the chain stopper on the stopper stop.

The direction of movement in the sense of this application is understood to mean the trajectory that the center of gravity of the respective platform carries out. The direction of movement may be a circular path (for example when pivoting) or a longitudinal movement or mixed forms thereof. Thus, for example, it is possible for a rotary movement to follow the rotary motion, or a lifting motion for a combined rotary-lift motion, and so on. Eventually, at the time the chainstopper hits the stopper stop runs up or rests on this, in the direction of movement achieved a discontinuity, the direction of movement changes so. This change in direction is of course accompanied by a corresponding force change, be it an additional introduction of a force at a platform end or a corresponding shutdown of a force at a certain point.

A particularly bendable tension element is favorable, since it allows a deflection of the force directions on the parking device in any way. Thus, for example, in a variant according to the invention, it is provided that one end of the tension element, irrespective of the position of the platform, for example fixed in the wall or on the ground, subsequently deflects the tension element by a first deflection roller on the platform, preferably of the lower platform is, the platform, preferably the lower platform has a second guide pulley for deflecting the tension element in the direction of a third, arranged on the stator pulley and the other end terminates at the lower and / or upper platform and is connected thereto.

By defining an end of the tension member, for example, on the wall or on the ground, the use of the lifting drive causes movement of the tension element, whereby a corresponding force on said second and third pulleys on the platform, whether the upper or the lower is transmitted , This allows the tension member to be connected to both the upper and lower platforms, that is, the platform already carrying the two pulleys. In this respect, the invention in this regard is very variable.

However, the variability is further increased by the further variant, according to which the other end of the tension element, ie that end which is not connected to the wall or connected to the ground, connected to the lifting bar. As a result, the entire design gains a high degree of variability, since the adjustability of the stops or the support on the pull rod makes the effective length of the tension element variable and adjustable. However, this embodiment also allows another, further described below variant.

In this context, it is favorable that a synchronization device is provided for the sides of the platforms. This synchronizing device is realized for example by a rigid chain, which is arranged in particular in the connection region of the traction element designed as a chain from the bottom to the first guide roller.

Such a synchronizing device is formed, for example, as a plate-link chain, whose tabs at least partially on the side facing away from the deflection roller carries pressure pieces, which lie against each other in the extended state of the chain and are therefore able to transmit pressure.

In a further embodiment of the invention it is provided that the tension element carries a chain stopper between the second and third deflection roller. The chain stopper is thus provided in the usually vertically extending, substantially parallel to the stator extending portion of the tension element. The chain stopper, when cooperating with a stopper stop, causes a decoupling of a part of the tension element from the pulling action.

Cleverly, the stopper stop is arranged on the device or on the stand.

In a preferred embodiment of the invention it is provided that the position of the chain stopper on the tension element adjustable is. This is a third way to change the behavior of the storage device with respect to the movement of the platforms and the angle for the parking and parking of vehicles. In fact, it should be noted that the upper platform in its path from the first to the second position, for example from bottom to top, moves in sections at different speeds, these areas depending on the location of the chainstopper at different speeds. Finally, the chain stopper, which cooperates with the stopper stop, causes the upper part of the bottle-like pulling element to be "switched off". This eliminates the deflection of the third pulley and thus a corresponding reduction, in fact halving the speed of the lower platform.

Cleverly, the position of the chain stopper on the tension element is selected depending on the position of the support on the drawbar with respect to the driver of the upper platform. In the first part of the movement, the upper platform is moved by the lifting bar, which is pulled from above by the pulling element. If the chain stopper is active, then the area on the third pulley of the tension element is powerless and the lifting bar transmits the force completely on the second pulley, which is movably arranged on the lower platform and at the same time supports the lifting bar below.

In this case, then affects the support of the drawbar with the driver together.

It is proposed that the Zugelementlängenausgleich for example as a spring, telescopic cylinder and / or Zugelementspeicher can be formed. The Zugelementlängenausgleich is suitably, for example, elastic, the elasticity counteracts due to the imprinted by the lifting drive force. An uncontrolled drop the tension element is safely avoided by this proposal, the tension element is always safely guided and controlled, so that no interference can occur. For example, it is possible that the Zugelementlängenausgleich is designed as a spring, which is able to stretch this spring under the influence of the lifting force and so the total length of the tension element is increased accordingly. The term spring is initially representational understand, that is, on the tension element, which is formed for example as a chain, for example, a coil spring or the like is installed at the end or in the middle. The term spring is also to understand functionally, namely such that, for example, the corresponding resilient, so elastic element, for example, a rubber band, is arranged parallel to the tension element and the unloaded tension element, due to the rubber band or the other, elastic element accordingly controlled stores.

In addition to the use of a spring, of course, the use of a telescopic cylinder is conceivable, wherein the cylinder, for example, is telescopic against a corresponding spring force.

The use of a tension element storage, for example, a kind of "cable roll" or the like, is possible. The use of a Zugelementspeichers has the particular advantage that a protection for the tension element is possible if, for example, the tension element is stored in a housing or the like.

Furthermore, it is possible that the Zugelementausgleich is arranged between the chain stopper and the connected either on the stand or on the lifting element Zugelementende. These embodiments will be further described in particular by the drawing, in these variants, the Zugelementlängenausgleich is not usually in the Zugelementbereich arranged, which is arranged on the lifting drive. By such a variant, the accessibility of Zugelementlängenausgleichs is considerably easier under certain circumstances.

In a variant according to the invention, in order to protect the tension element length compensation, it will not be arranged in the area in which the considerable lever loads for the respective platform area are derived. In principle, however, it is possible to arrange the Zugelementlängenausgleich in this area, in which case the Zugelementlängenausgleich is preferably provided in accordance with a stable design. Such a variant is for example in Fig. 11 shown.

Furthermore, the invention proposes that in the range of motion of the platform, starting from the lower position, first the lifting drive lifts the platform at least on one side. The tensile force acts on the tension element until it is pulled taut and then the chain stopper rests against the stopper stop and the tension element lifts the platform.

In the first section of this range of motion, the one-sided lifting movement will pivot the platform. With respect to the access while the front area is pivoted, the rear, the driveway facing away from the area forms a fulcrum. The advantage lies precisely in the fact that can be adjusted by the appropriate setting of the stopper stop or the chain stopper, the swivel angle or swivel range and so the structural opposites can be optimally utilized. In this case, this proposal comes with a very simple embodiment of the tension element, since in the unloaded position (when the platform is raised on one side, so pivoted), the tension element is simply stored, for example in a tension element memory. This tension element memory is designed, for example, as a chain case or the like and has cleverly a corresponding care or maintenance unit for the tension element. By this it is possible to lubricate the tension element accordingly or to clean.

Through this care or maintenance unit, which is cleverly arranged, for example, in a closed chain case, the tension element, over which indeed considerable forces are passed, can be oiled or cleaned during operation. This leads to the most reliable operation of the entire storage device.

It is proposed that during the lifting of the platform, the tension element removed from a Zugelementspeicher, for example, is pulled out. This proposed variant occurs in addition to the also counting to the invention arrangement with a Zugelementlängenausgleich. The advantage of this variant described here is that it is mechanically simple to implement, a Zugelementlängenausgleich is formed for example as a spring or the like and correspondingly structurally complex. Both variants offer different advantages in the respective application areas.

Cleverly it is provided that during the lowering movement, the unloaded tension element, in particular by a shear-resistant Zugelementebereich, is stored in the Zugelementspeicher. As also shown in the drawing, the tension element is stored in the tension element memory, for example, rolled or folded. To ensure that the tension element also passes safely into the tension element storage, a shear-resistant Zugelementbereich is provided which ensures the relief of the system, for example, the last phase of the lowering in the lower position, ensures that the tension element reliably enters the tension element memory. As a rule, the platform is already in the rear area at the desired end position of the lower position on and only the front area is swung down. In this position, the tension element is already relieved and can get into the tension element memory.

Furthermore, both arrangements in which the free end of the tension member (the end which is not attached to the ground or to the pit wall) are either suitably fixed to the standoff (for example on the stand or to members of the stand), as well also arrangements in which a free, open other end of the tension element is realized. On a mechanical definition of this other end, it is not essential because the tension element is indeed used in two different phases. In a first phase, the tension element is relaxed, in the second phase it gains a function through the contact of the chain stopper on the stopper stop and is pulled tight. The projecting behind the chain stopper region of the tension element does not need to be determined, but may be free or not bound as a supernatant.

In a variant, it is provided that the tension element comprises at the other end a rod, in particular a threaded rod for receiving the chainstopper. By using a rod or threaded rod in particular, it is possible to adjust the chain stopper infinitely. In this respect, the tension element is not necessarily homogeneously formed, the tension element may very well also have different, heterogeneous tension element areas, correspondingly optimized to the respective area of use. In addition to a double-sided articulated Zugelementbereich it is for example possible to arrange a push-rigid, one-sided articulated Zugelementbereich and just a self-rigid (because not deflected) Zugelementbereich in the region of the rod. Of course, all other variants are also conceivable.

In the drawing, the invention is shown schematically. Show it:

also in a side view of a further variant of the storage device according to the invention in the lowest position.

In Fig. 1 the storage device according to the invention is shown in a first, lower position. In the position shown here, a vehicle approaching in the driveway 3 can enter the upper platform 1. The entry level of the upper platform 1 is flush with the driveway 3.

Lowered against this is the lower platform 2. The entire arrangement is so far, for example, in a pit, which the vehicle is sunk in the lower platform 2 in the pit.

The storage device according to the invention further consists of a stand 4, which is arranged on the side facing away from the driveway 3 on the parking device.

To bring the platforms 1, 2 from the first to the second position, a lifting drive 9 is provided. This is designed for example as a working cylinder. Since the angular position of the platform 1, 2 relative to the substantially vertically arranged lifting drive 9 changes, the upper platform 1 and the lower platform 2 are each connected by articulated bearings 91, 92 to the lifting drive 9. These hinged bearings 91, 92 define a fixed distance F between the upper platform 1 and the lower platform 2. Around these bearings 91, 92, the upper and lower platforms 1, 2 are pivoted upon lifting and lowering of the platforms 1, 2. The linear actuator has several functions. On the one hand, the lifting drive 9 is used to execute a height-adjustable stroke H and on the other hand, a fixed distance F between the platforms 1, 2 with the pivot points by the bearings 91, 92 defined (see Fig. 4 ).

To the left and right of the platform 1, 2 are corresponding lifting actuators 9, which lie one behind the other in the side view and are therefore hidden. The lifting drive 9 is arranged in the front half with respect to the driveway 3 on the platforms.

The stand 4 serves as a guide for the rear end of the platforms 1, 2.

It is in principle also possible to realize a reverse construction or arrangement, such that the stator 4 faces the driveway 3.

The stand 4 has a guideway, in the corresponding, not shown guide carriage of the platforms 1, 2 are guided.

In order to fix the upper platform 1, due to iherer articulated mounting with the hinge 91, it is provided that on the storage device on the one hand a stop 5 and on the other hand a support 6 is provided. In the in Fig. 1 the position shown on the stand fixed support 6 ', 61 is effective, on which the upper platform 1 is located. Furthermore, this position is determined by the stop 50, which is located on the lifting rod 7. For this purpose, the upper platform 1 on a driver 10. This driver 10 is located for example on a driver plate 12 which is pivotally connected by the hinge 11 to the upper platform 1. The driver 10 is thus part of the upper platform 1. A vehicle entering from the driveway 3 first loads the area of the upper platform 1 which lies on the right of the joint 91. A tilting moment occurs in the clockwise direction, which does not occur due to the support 6 'on the upright 4 can be caught.

Since the driver 10 describes the same tilting movement as the upper platform 1, the driver 10 abuts against the stop 5 'of the lifting bar 7.

The position of the upper platform 1 is fixed in this position.

According to the invention, the interaction of a stop 5 and a support 6 is described. According to the invention is also provided to arrange stop 5 and support 6 on the stand 4.

According to another variant of the invention, it is provided to arrange stop 50 and support 60 on the lifting bar 7.

The lifting bar 7 has a foot area 70, with which the lifting bar 7 is connected to the lower platform 2.

The stopper 5 'takes on maximum the counterforce corresponding to the weight of the lower platform 2 including the lifting bar 7, and a possible vehicle weight, on.

Thus it follows that in the in Fig. 1 shown position of the stop 5 ', 50 is ultimately formed by an element of the lower platform 2, whereas the support 6 is located on the stand.

An essential advantage lies in particular in the arrangement using a particular flaschenzugartigen or also deflected tension element. 8

The tension member 8 is connected at its first end 86, for example, to the bottom of the pit. The tension element 8 is then deflected by a first deflection roller 81 to the left. The tensioning element 8 then runs essentially parallel to the longitudinal extension of the lower platform 2. In the region of the upright 4, a second deflection roller 82 is provided on the lower platform 2. Through this, the tension element 8 is deflected at right angles from above, in the direction of the third deflection roller 83.

The third deflection roller 83 deflects the tension element 8 by 180 °. The other end 87 of the tension element 8 ends at the upper region of the lifting bar 7.

The lifting bar 7 can thus be changed over the tension element 8 upon actuation of the lifting drive 9, according to the following figures, first by a stroke V ₁ . The stroke V ₁ is defined by the (adjustable) position of the support 60 with respect to Driver 10. As the train progresses on the tension member 8, the lifting rod 7 pulls the upper platform over the stroke V ₂ into the upper position by means of the carrier 10 resting on the support 60. The stroke V ₂ is the (variable) distance of the upper edge of the upper platform 1 from the abutment 51. It is clear that by an adjustability of V ₁ and V _2, the angles of attack of the platforms are adjustable. This is considerably advantageous both for conversion purposes or considerable facilitation of adaptation on site (for example, during installation or conversion), as well as for a dynamic adaptation of the platform geometry (distance or height) to different vehicle types. The dynamic adjustability can be supported, for example, by control actuators. The stops 5, 51 or pads 6, 61 are equipped with controllable, positionable actuators. This is another advantage.

In the in Fig. 2 shown first intermediate position is a retraction and extension of the upper platform no longer possible. The upper platform 1 is already lifted slightly from the level of the driveway 3. For this purpose, the lifting drive 9 is activated, the piston rod 93 of the lifting drive 9 emerges. As a result, the portion of the tension member 8 between its end 86 and the first guide roller 81 increases. Since the total length of the tension member 8 is constant, this increase in this area must be accompanied by a decrease in another area. The rear area of the upper platform 1 is slightly raised from the support 61. This stroke movement is due to the fact that the tension element 8 is deflected over the third deflection roller 83 and the path is correspondingly halved to the entire effective length of the tension element 8 in the region between the deflection roller 81 and its end 86 to provide.

The driver 10 of the upper platform 1 lies on the support 60, which is located on the pull rod 7, on. As a result, the lifting force is transmitted to the rear part of the upper platform 1. Also, the rear end of the lower platform 2 rises and is already tilted slightly. For this purpose, it is favorable that the platform 2, as well as the platform 1, are each hingedly connected to the carriage of the stand 4. For the lower platform 2, the support 60 forms a stop which defines the maximum approach state of the two platforms 1, 2. It is understood that the stops 50, 5 'or supports 60 are adjustable on the lifting rod 7 via threads and are preferably designed as threaded nuts.

In the Fig. 3 shown second intermediate position is still not useful for driving on the platform 1, 2.

In the region between the second deflection roller 82 and the third deflection roller 83, approximately in the upper third of the stator 4, the tension element 8 carries a chain stopper 80, which in the second intermediate position now shown, interacts with the stopper stopper 40. It can be clearly seen that the platforms 1, 2 pass through a considerable angular range, that is, they are inclined accordingly. This tendency stems from the uneven movement of the front and rear ends of the platforms 1, 2 Fig. 3 shown time, the upper part of the tension element 8, namely that which is directed over the third guide roller 83, "turned off". This is shown by the slack, sagging end of the adjoining the pull rod 7 end of the tension element 8. At the present time, the pull rod 7 is no longer pulled by the tension member 8 upwards, but pushed by the tension member 8 via the second guide roller 82 upwards.

As before, the driver 10, which is pivotally connected to the upper platform 1, on the support 6 ', 60 of the pull rod 7 resting. The support 60 has a double function. It forms a stop for the lower platform 2, as explained above, and for the upper platform 1 it is a support.

In the, in Fig. 4 shown upper position, the piston rod 93 is further extended to the maximum stroke H, the effective length of the tension element 8 between the first roller 81 and the connection point 86 has further increased to the maximum distance, the distance of the upper platform 1 of the Stopper stop 40 arranged above it has been reduced again. Since the position of the lifting bar 7 is not exactly above the hinge point 20, a slight rotational movement is impressed counterclockwise in the upper platform 1 by this movement. The upper and lower platforms 1, 2 are mounted on the lifting drive 9 and the bearings mounted thereon 91, 92 in each operating state of this arrangement at a fixed distance F.

The stop 51 is a stop for the upper platform 1, which indirectly via a kinematics with the driver 10 and the support 60 also forms a stop for the lower platform 2.

The arranged on the tension element 8 scenery 85 touches in the position shown now the limit switch 84 and stops the lifting drive 9 at.

The interaction of the limit switch 84 and the link 85 is referred to as stroke limiting device 100 according to an advantageous variant of the invention. There are different variants of how this stroke limiting device 100 is configured. In addition to the just described variant, it is possible that a stopper 8 arranged on the stopper is provided, which cooperates with a stop. The stop is for example on the frame or fixed to the lower or upper platform 1, 2 and limits the mobility with respect to the tension element 8. The hydraulic system has a limit switch, which stops in case of overload corresponding to the pump. This overload is achieved when, despite further pressure build-up, the platform can not be moved, namely, when the arrangement has arrived at the stop.

In Fig. 5 a further variant of the stroke limiting device 100 is shown. In the embodiment shown here sits on the lower platform 2, a platform stop 203, which, when the lower platform 2 is raised, cooperates with the stop 101. Again, the further stroke is limited by this.

Cleverly, the arrangement is carried out so that the stopper 101 is provided on a running example, as a threaded rod guide rod 201 and the stop 101 is adjustable, for example as a nut on this threaded rod. Thus, a stroke limitation can be realized adjustable in a simple manner.

The design with the guide rod 201 offers yet another, surprising advantage. It is namely possible to provide a position stop 200 on the guide rod 201 in the lower region, whereby the lower, lowered position of the lower platform 2 is adjustable. This can, for example, at different pit depths, in which the storage device is installed, be advantageous, the variability and usability is thus further increased significantly.

It is not specified, only as described, to realize a corresponding position stop, but is provided that for the lower platform 2, a particular adjustable position stop 200 is provided. Other variants may also be provided here, although of course the use of the threaded rod with respect to a stepless adjustment of the position stop 200 involves considerable advantages.

So shows, for example, the Fig. 5 the interaction of the pallet stopper 203 with the position stop 200 in the lowered position. If you compare the solution after Fig. 5 with the variant Fig. 1 it is easy to see that, contrary to the solution Fig. 1 , the pallet is not completely rests on the pit floor, but is slightly spaced. This measure can be specified by the position of the position stop 200.

In Fig. 6 the stroke limiter 100 is shown by the guide rod 201 in use. The pallet stop 203, which moves along with the lower pallet 2, abuts the stop 101 from below and thus limits the further vertical movement. Thus, a further parameter for the setting of the storage device is created.

In a further variant, it has been found that it is favorable if an upper platform 1 projecting into the driveway is provided. This is for example in Fig. 5 shown. The protruding end of the upper platform 1 is indicated by dashed lines. It turns out that with the same position of the storage device, ie the same position of the platform 1 on the stand 4, a different angle of inclination of the upper platform 1 results. The solution in which the driveway 3 protrudes into the access road or the driveway 3 is slightly flatter, the resulting distance, the usable for the parking of the vehicle height between the bottom of the upper platform 1 and the lower platform 2, is correspondingly higher , This may include a further variant in order to create a sufficiently high parking space even in difficult or cramped conditions on the lower parking space, the lower platform 2.

The upper platform 1 is now against the stop 51 of the stator 4 and is still held by the support 60 of the pull rod 7, by the driver 10. Thereby, the angle formed by the longitudinal extent of the lifting bar 7 and the longitudinal extent of the upper platform 1 is stiffened and secured, that is, fixed to the stand, so that the lower platform 2 does not tilt down when driving through a vehicle.

The storage device allows in particular by the location of the arranged on the stand support 61 and stop 51 and arranged on the lifting bar, therefore movable stop 50 and support 60 with only one arranged on a range lifting drive 9, using the tension element 8, a very complex variety of different kinematics of the upper and lower platforms 1, 2. Depending on how the distance from the stop 5, 50, 51 to the support 6, 60, 61 is selected, at which time the chain stopper 80, that via the third guide roller 83rd guided part of the tension element 8 turns off, a variety of different types can be realized with a storage device.

In the FIGS. 7 . 8th . 9 and 10 a further variant of the invention is shown. The storage device according to the invention shown in various positions corresponds with the respective views, the positions with the FIGS. 1 to 4 such that the respective lowest position in Fig. 1 respectively Fig. 7 and the uppermost position in Fig. 4 or 10 is shown. Also, the numbering is the same. On the interaction of the different Stops 5, 5 'or pads 6, 6' and so on is therefore not discussed again at this point, the in FIGS. 7 to 10 shown variant is in this respect equivalent to the in Fig. 1 to Fig. 4 shown.

Different are the variants after Fig. 7 to 10 to the variant Fig. 1 to 4 with regard to the leadership of the tension element. 8

In the first variant after Fig. 1 to 4 is at the upper end of the stator 4, a third guide roller 83 is provided, which causes the fixed end 86 opposite end of the tension element 8 is lowered again and opens on the lifting rod 7 with its free end 88.

In the FIGS. 7 to 10 shown variant dispenses with the third guide roller 83, the corresponding length of the tension element 8 from the guide roller 83 to the lifting rod 7 and the connection of the tension element 8 to the lifting rod 7 is saved. It is proposed that the free end 88 of the tension element 8 opens into a bearing 801 on the stand 4 in the upper region and is suspended. The variant after Fig. 7 to 10 is therefore cheaper in the realization as the variants Fig. 1 to 4 ,

In Fig. 3 and 4 It is shown that advantageously for receiving an excess length of the tension member 8, in particular during the lifting and lowering operation of the parking device preferably a Zugelementlängenausgleich 800 is provided. This Zugelementlängenausgleich 800 takes on the excess length of the tension element 8, which in the Fig. 3 and 4 is shown as a slack, sagging angled end. The Zugelementlängenausgleich 800 is provided between the third guide roller 83 and the end 87.

The same is also true in the variant Fig. 7 to 10 shown, although here the Zugelementlängenausgleich 800 is designed for example as a spring and is able to control controlled length, so that the whole matter is better controlled.

Subsequently, first the lifting process after FIGS. 7 to 10 described in turn.

In Fig. 7 the lower position is shown, a vehicle can drive from the driveway 3, the upper platform 1. By counting the invention also fixing the platforms 1, 2 with the stops 5, 5 ', 50 or 51 and pads 6, 6', 60 and 61, the platforms 1 and 2 are securely fixed in the respective loading and unloading.

Trained as a working cylinder linear actuator 9 is completely collapsed, the arrangement is in the lower position.

It should be noted that the chain stopper 80, which is located between the stopper stopper 40 and the bearing 801, initially has sufficient distance from the chain stopper 40. In the example shown here, the Zugelementlängenausgleich 800 between the chain stopper 80 and the bearing 801 is arranged, but there are also other variants.

If now the working cylinder of the lifting drive 9 pressurized, the piston rod 93 emerges, the first guide roller 81 moves away from the ground with the fixed end 86 of the tension element 8. The movement of the piston rod 93 ultimately causes a force on the tension element 8. Die Overall length of the tension element 8 is increased by the immersion of the piston rod 93, this length is taken from the Zugelementlängenausgleich 800, this is somewhat elongated than 800 'shown.

Although it is a force on the tension element 8 by the movement the lifting drive 9 exercised, but this impressed force only causes the tension element 8 is lengthened accordingly, but there is no lifting of the approach 3 end facing away from the platform. The front part of the platform, which is arranged in the region of the lifting drive 9, is raised. This unilateral movement leads to a rotational movement, indicated by the curved arrows 13, 23 (see Fig. 8 ) of the platform 1, 2, about the joints 11, 20. This pivotal movement 13, 23 stops until the chain stopper 80 runs onto the stopper stopper 40. In this situation, it then happens that the further impression of force in the tension element 8 can not lead to an elongation of the tension element 8, since now the actually effective train length is determined by the concern of the chain stopper 80 on the stopper stopper 40. At this time, the direction of movement of the platforms 1, 2 will change, as in Fig. 9 is shown.

Another descent of the piston rod 93 on the lifting drive 9 or, which is analogous, further lifting of the platforms 1, 2 in the front area, by whatever lifting means, now causes that also the distance of the first guide roller 81 fixed to the ground Zugelementende 86 increases. However, since the tensile length of the tension element 8 is fixed by the abutment of the chain stopper 80 on the stopper stopper 40 and thus constant, the Zugelementlänge entering in the region between the first guide roller 81 and the Zugelementende 86 must the area of the tension element 8 between the chain stopper 80 and the second guide roller 82 are removed. Because this area, in Fig. 9 marked as 89, correspondingly reduced, the second guide roller 82 moves toward the stopper stop 40 fixed to the stand, it is raised. There is a uniform lifting of the two platforms 1, 2 along a rectilinear movement, represented by the arrows 14, 24th

This vertical lifting movement 14, 24 stops until the platforms 1, 2, as well as in Fig. 4 described reach their upper end position. As with Fig. 4 described, then act the platform 1, 2 with the respective stops or pads together. The mode of action here for setting the platforms 1, 2 in these positions is the same. In particular, the lifting drive 9 is switched off by the actuation of the limit switch 84 by the Kullisse 85 and optionally fixed or blocked in order to avoid accidental lowering safely.

In the Fig. 1 to 4 or 7 to 10 shown variants achieve different motion sequences or kinematics.

According to the first variant Fig. 1 to 4 results from the pulley-like design of the tension element 8, a different platform speed of the upper platform 1 and the lower platform 2, in their respective rear region. However, since the front region is arranged in each case on the cylinder of the lifting drive 9 and therefore each has the same speed, a pivoting movement takes place. The movement of the two platforms 1, 2 is therefore not parallel.

This applies as long as the chain stopper 80 does not yet cooperate with the stop stop 40. Is this then on (see Fig. 3 or Fig. 8 ), the respective movement of at least one platform 1, 2 changes.

In contrast, the second variant is after Fig. 7 to 10 first a pivoting (see movement 13, 23) and thereafter a vertical movement (arrows 14, 24) are provided.

An essential advantage is that with the same basic structure of the storage device only with changed Design of the tension element 8 different kinematics can be realized. Especially in cooperation with the manifold adjustment of the stops 5 'or 6 editions and so on, the storage device according to the invention is equipped with a high variety of equipment.

The Zugelementlängenausgleich 800 can be installed at any point in the tension element 8.

As in Fig. 7 shown, for example, this is located in the upper region, ie between the chain stop 80 and the tension element 88 fixed to the stand. But it is also possible to arrange the Zugelementlängenausgleich between the chain stopper 80 and the second guide roller 82, or between the guide roller 82 and the first guide roller 81. It is also possible to arrange the Zugelementlängenausgleich 800 between the first guide roller 81 and the fixed to the bottom end 86 of the tension element 8. It should be noted that in this application, when then the chain stopper 80 applies to the stopper stopper 40, a significant tensile load on the lower portion (between the fixed end 86 and the stopper stopper 40) on the tension member 8 and then accordingly the Zugelementlängenausgleich 800 has to be stable accordingly.

Of course it is possible to adjust the tension element length compensation 800 as in Fig. 3 or 4 indicated to arrange in the last segment of the tension element 8.

In Fig. 11 is a further inventive variant exemplified. The variant shown here is with the in Fig. 7 very similar, which is why only the differences to Fig. 7 will be received.

Instead of a length compensation 800 after Fig. 7 is in this Variant a tension element memory 804 is provided. It is hereby noted that the tension element memory is generally also provided as a special embodiment of the Zugelementlängenausgleiches, but in a further variant but also independently and without reference to a Zugelementlängenausgleich can be used.

The tension element memory 804 is used to hold the unneeded, in the lower position slack daliegenden tension element 8. It is indicated that the tension element 8 is inserted in a meandering manner in the Zugelementspeicher 804. This is effected in particular by a stiff thrust chain region 803 which, for example, can only be bent to the left, but otherwise is stiff. During the lowering movement, precisely this push chain region 803 is pushed to the left, whereby the tension element 8 passes into the tension element memory 804 and is deposited. In this situation, no lifting force or holding force is transmitted to the rear area of the platforms 1, 2 via the tension element 8.

Now lifts the platform 1, 2 by the lifting drive 9 and increases the distance of the first guide roller 81 of the pit floor, the tension element 8 is removed from the Zugelementspeicher 804. The tension element 8 tightens until the chain stopper 80 firmly abuts against the stopper stopper 40. In a further lifting movement, the total length of the tension element 8 is now fixed and the guide rollers 81, 82 roll over the tension element 8, and the rear portion of the platform 1, 2 is raised. It is clear that the position of the chain stopper 80, the time at which is transferred from a pivoting movement in a lifting movement, is adjustable. Of course, the same applies analogously for the lowering movement.

In the in Fig. 11 In the variant shown, the chainstopper 80 always rests on the stop 40. But since there is no lifting power, no force is transmitted here either. Cleverly, the tension element 8 is equipped in this report with a rod 802, it forms a free, projecting end 88 'of the tension element 8 from. In the variant after Fig. 7 the other end 88 is fixed to the support 801. But that does not matter because no forces are transmitted in this area. It is clear that the length compensation can be saved by this variant. The construction is considerably cheaper.

But since no tensile force on the tension element 8, nothing happens by the concern of the chain stopper 80 on the stopper stop 40. An elongation of the tension element 8 only leads to a tightening until it is pulled taut and then actually the chain stop 80 acts with a corresponding force against the stopper stop 40. From this point on, the rear area of the platforms 1, 2 is then moved upwards, in particular via the deflection roller 82, when the lifting drive 9 is still active, that is to say, the parking device moves from the lower to the upper position.

Cleverly, the rod 802 is formed as a threaded rod. The chain stopper 80 is formed for example as a nut, resulting in a stepless adjustability of the chainstop, which of course any adjustment options can be realized.
