Description

DEPLOYMENT DEVICE FOR MOTOR VEHICLES

The invention relates to a parking device for motor vehicles arranged one above the other, can be raised and lowered by a lifting device and thereby selectively connectable to a driveway platforms, which are each connected via a bearing with the lifting device.

Such storage devices are usually installed in buildings, which have different dimensions, so that the storage devices must be adapted to the geometry of the slot for optimum space utilization. In addition, storage devices of this type are used for motor vehicles of different sizes, so that it makes sense for optimum space utilization to adapt the position of the platforms in the respective end positions to the size of the motor vehicles.

This is usually achieved in that different sized components are used to build such a storage device, these components are then assembled in place to the finished system. For this purpose, it is necessary to produce different sized components and to make each available, since the installation in advance often can not be determined exactly which size is desirable, for example, when deviations from the original plans. In addition, it is not possible to subsequently change such a storage device in their dimensions, without having to make quite significant modifications.

It is an object of the invention to provide a generic storage device in such a way that their size can be easily adapted to the desired dimensions. This object is achieved in a storage device of the type described above according to the invention that the distance of at least one of the bearing of the lifting device in the direction of displacement is infinitely adjustable.

A stepless adjustability makes it possible during construction or later to adjust the distance of the bearing of the lifting device, so that different positions of the bearing can be achieved with the same lifting device during the movement of the lifting device, and thus is an optimal adaptation to building dimensions and vehicle sizes possible.

In particular, it is advantageous if the adjustable bearing is connected via at least one threaded spindle with the lifting device and fixed by acting on the threaded spindle holding elements in its distance from the lifting device. By rotating the threaded spindle or by rotating screwed on the threaded spindle holding elements can thereby realize different positions of the bearing relative to the lifting device, and that continuously. Larger modifications to the system are not necessary, and it is possible to achieve different positioning of the platforms in operation with always the same components, in particular with the same lifting devices.

It when the adjustable bearing is connected via two juxtaposed threaded spindles with the lifting device and is determined by acting on the threaded spindles holding elements in its distance from the lifting device is particularly advantageous. By using two such threaded spindles an anti-twist device is additionally achieved, except This is achieved by a distribution of the male payloads and thus increasing the stability of the overall arrangement.

It is advantageous if the threaded spindles are connected to each other by at least one transverse web, in particular, the threaded spindles can enforce the crosspiece.

In a preferred embodiment it is provided that for fixing a transverse web or a support for the bearing on opposite sides of the crosspiece or support on a crosspiece or support passing through screw threaded retaining elements are clamped against the support of the crosspiece. As a result, the position of the crossbar or carrier is fixed to the threaded spindle, but this position can be changed when the screwed-on holding elements are released and then stretched in the new position against the carrier and cross bar.

It is particularly advantageous if the lifting device is a piston-cylinder unit and at least one bearing is fixed on the cylinder. Due to the displacement of the bearing on the lifting device, it is possible to raise the piston-cylinder unit always up to its end position, without special limit switches are necessary to stop the piston-cylinder unit in an intermediate position. Due to the height adjustment of the bearing on the cylinder, the bearing can be arranged in any desired height even with fully extended piston-cylinder unit.

It is particularly advantageous if the bearing fixed to the cylinder encloses the cylinder or the piston and is thereby displaceably guided on the cylinder or piston during a distance adjustment. Through the tour on the Unfortunately, the stability is substantially increased because the bearing is held in the axial direction by the threaded spindle and in the transverse direction by the guide on the cylinder.

In a particularly preferred embodiment it is provided that a bearing is part of a bearing assembly having a fixed cross-piece on the cylinder, at least two fixed thereto, parallel to the cylinder threaded spindles and a set of holding elements on the threaded spindles crosspiece, which forms the camp or this one is wearing.

In particular, the transverse web forming the bearing can have a sleeve which tightly surrounds the cylinder or the piston and thus leads to guidance and increase in stability.

The holding elements can be screwed onto the threaded spindles nuts. In another embodiment, it is provided that the holding elements are clamped against the threaded spindle clamping screws.

It is particularly advantageous if a plurality of bearing arrangements are arranged at a distance from one another on the cylinder, each of which is assigned to a platform. The cylinder is then the carrier for the individual bearing assemblies, the bearing assemblies on the cylinder can be set in always the same position, the adjustment of the distance, however, takes place via the threaded spindles of the bearing assemblies.

In a modified embodiment, it is provided that a lower bearing is held steplessly adjustable in height at a higher camp. In this case, only the higher-lying bearing is connected to the cylinder, the lower bearing is carried by the higher-lying bearing or firmly connected to this parts.

In a preferred embodiment it is provided that a lower-lying bearing is held on at least one threaded spindle, which in turn is held by a carrier element on at least one threaded spindle fixed to the lifting device, and that each threaded spindle carries a bearing held on the threaded spindle at an adjustable height bearing. Thus, each bearing is assigned its own threaded spindle, wherein the lower threaded spindle is supported by the upper threaded spindle.

It may also be provided that at least two bearings are held vertically adjustable on at least one threaded spindle held on the lifting device, preferably two juxtaposed, continuous threaded spindles are used which carry height adjustable at least two different levels of height.

It is advantageous if the bearings are guided displaceably in a stationary vertical guide, so that the guide does not have to be taken over by the lifting device alone, but essentially by the vertical guide.

In particular, it can be provided that the bearings together form a lifting slide, which is guided displaceably in the vertical guide.

The following description of preferred embodiments of the invention is used in conjunction with the drawings for further explanation. Show it: Figure 1: a perspective view of a storage device with two superimposed platforms in the lowered position;

Figure 2 is a view similar to Figure 1 with the platforms in the raised position;

FIG. 3 shows an enlarged perspective view of a piston-cylinder unit with two bearing arrangements fixed thereto;

Figure 4: a bearing assembly according to the embodiment of Figure 3 with short threaded spindles;

Figure 5: a bearing assembly similar to Figure 4 with long threaded spindles and

Figure 6: a modified embodiment of a lifting device with two height-adjustable bearing assemblies.

The storage device 1 shown in the drawing is placed on a flat bottom surface 2 of a building. This is located opposite a driveway 3 at a lower level, the bottom surface 2 is bounded by a vertical, adjoining the driveway 3 side wall 4. For example, the floor surface 2 may be part of a pit provided in a building with the driveway 3 at the level of the environment. On both longitudinal sides of the bottom surface 2, a frame 5 is placed in each case. Each of the same and mirror image formed to each other frame 5 has a front, vertical support 6, a rear, vertical support 7 and a connecting the two at the top web 8. Between the two frames two platforms 9, 10 are mounted one above the other, which are adjustable in height, so that the two platforms 9, 10 can be selectively connected to the driveway 3, so that motor vehicles on the driveway 3 on the platforms 9, 10 and drive from can shut it down again. Both platforms have a flat footprint 11 and these laterally delimiting side walls 12, 13.

Instead of using a frame 5 with vertical support 6, vertical support 7 and this connecting at the top web 8 can also be a modified storage of the two platforms 9, 10 are made, which is not shown in the drawing. In this modified storage, the vertical support 6 is firmly connected to the ground, while the rear support 7 is rotatably mounted on the ground and remains approximately perpendicular by a guide on the upper platform 9. The platforms are thus guided on the front, vertical support 6, and the upper platform 9 also takes over the leadership of the rear support. 7

In both cases, the front support 6 is designed as a vertical guide for a lifting carriage 14, these are, for example, strong C-profile rails, which face each other with their open sides. Inside this profile rails a lifting 14 is mounted vertically adjustable, the height displacement is effected by a piston-cylinder unit 15, the piston rod 16 is supported on the bottom surface 2 and the cylinder 17 during extension of the piston rod 16 the cylinder 17 is thereby raised. This cylinder 17 is connected to the lifting carriage 14 and takes it with the lifting movement.

Two bearings 18, 19 are arranged one above the other on the lifting carriage 14, the upper platform 9 is pivotably mounted on the upper bearing 18 about a horizontal axis of rotation running transversely to the longitudinal direction of the platform 9, the lower platform 10 correspondingly on the lower bearing 19.

With lowered platforms, the lower platform 10 rests on the floor surface 2 on or on stops not shown in the drawing on the rear support 7 of the frame 5. The upper platform 9 rests on stops 20 of the rear support 7 of the frame 5 (Figure 1) , When lifting the lifting carriage 14 both platforms 9, 10 are pivoted, the lower platform 10 about its trailing edge or about an axis of rotation, which are formed by stops on the rear support 7, the upper platform 9 about an axis of rotation, formed by the stops 20 becomes. In principle, it is possible to bring the platforms from a lower position, in which the upper platform 9 adjoins the driveway 3, to an upper position by means of such pivoting, in which the lower platform 10 adjoins the driveway 3. But relatively strong inclinations of the platforms 9, 10 are necessary.

In the embodiment shown in Figures 1 and 2, therefore, care is taken to ensure that the platforms are also raised or lowered in addition to their pivoting.

For this purpose, the two platforms are hinged at their end facing away from the driveway 3 via substantially vertically extending links 21, in addition, the lower platform 10 bears on the outside. side of its side cheeks 12, 13 two pulleys 22, 23, and that a front pulley 22 immediately adjacent to the front support 6 and a rear guide roller 23 immediately adjacent the rear support 7. To these pulleys 22 and 23, a rope 24 or a chain is placed Whose one end is held stationary below the guide roller 22 on the bottom surface 2, while the opposite end above the rear guide roller 23 at the upper end of the frame 5 is held stationary. The cable 24 thus extends from the rear guide roller 23 approximately parallel to the rear support 7 upwards.

When the cable 24 is stretched, an increase in the lower platform 10 directly leads to the fact that the rear guide roller 23 is raised, thus there is a parallel lifting of the lower platform 10, which extends over the lifting carriage 14 and the handlebar 21 on the upper platform 9 transmits.

If the rope 24 is chosen so long that it is not tensioned on lowered platforms, but hangs loose, as shown in Figure 1, then occurs when lifting the lower platform 10 through the lifting 14 still no lifting in the rear Pulley 23, but it is first carried out in the manner described a pivoting of the two platforms, but it increasingly stretches the cable 24 until it is finally fully stretched and then pivots the platforms on further lifting the platform 10 in the manner described, not further but raises.

In Figure 2, the platforms are shown in the raised position. To form the lifting carriage 14 in the embodiments shown in Figures 3 to 5 on the cylinder 17 at a distance from each other two bearing assemblies 25, 26 defined, which are constructed the same in the illustrated embodiment, it will therefore be explained below only one of the two bearing assemblies , Each bearing assembly comprises an upper transverse web 27 with a sleeve 28 through which the cylinder 17 is pushed. In the region of the sleeve 28, this surrounds the cylinder closely, the transverse web 27 is fixed at this point on the cylinder 17, for example by jamming or welding.

The transverse web 27 has two through holes on two opposite sides, through which a respective threaded spindle 29, 30 is inserted. The two parallel to each other downwardly projecting from the transverse web 27 threaded spindles 29, 30 each carry above and below the transverse web 27 a nut 31 and 32, and these nuts 31 and 32 are clamped against the transverse web 27, thereby the threaded spindles 29, 30th are determined in the transverse web 27.

At the lower end of the threaded spindles 29 and 30, a similarly constructed transverse web 33 is pushed, which also tightly surround the cylinder 17 via a sleeve 34, but in contrast to the transverse web 27 is not fixed in the longitudinal direction of the cylinder 17, but against this freely displaceable is. Also in this area of the cross bar 33, the threaded spindles 29, 30 on opposite sides of the cross bar 33 nuts 35, 36, through which the cross bar 33 is fixed to the threaded spindles 29, 30. By loosening the nuts 35, 36 and screwing the same on the threaded spindle 29, 30, the position of the transverse web 33 can be changed continuously, that is, the distance of the transverse web 33 from the crosspiece 27th The transverse web 33 forms the bearing 18 or 19, on which in each case one of the two platforms 9, 10 is mounted. This is symbolized in FIG. 3 by a bearing opening 37.

The upper bearing assembly 25 is fixed to the upper end of the cylinder 17, the bearing assembly 26 at the lower end of the cylinder 17, and by the threaded spindles 29, 30 and the adjustment, the transverse webs 33 relative to the attachment points on the cylinder 17 can be adjusted in their distance continuously. It is possible to use different lengths of threaded spindles 29, 30, as will become apparent from Figures 4 and 5, so that optionally different sized adjustment paths are available.

When mounting the storage device 1, it is therefore possible to bring the bearings 18, 19 respectively in the desired height relative to the cylinder without major structural changes are necessary.

The transverse webs 27 and 33 also form parts of the lifting carriage 14, which is guided in the front support 6 in the vertical direction. For this purpose, the transverse webs 33 and / or the transverse webs 27 may be provided at their ends with guide elements 38, for example with caps made of a material with a low coefficient of friction or rollers not shown in the drawing, on the lateral legs of the cross-sectionally C-shaped front support Abut 6 and thereby experience a lateral guidance.

The lifting carriage is then formed by the cylinder 17 and the two bearing arrangements 25 and 26 arranged thereon. indirectly on the piston rod 16 and relative to the front support 6 slidably.

In the embodiment of Figures 3 to 5 two identically constructed bearing assemblies 25 and 26 are set at different points of the cylinder 17 at this.

In contrast, the cylinder 17 of the arrangement of Figure 6, which is similarly constructed and in which corresponding parts bear the same reference numerals, only at its upper end a transverse web 27. Furthermore, in this embodiment, the piston-cylinder unit is not inside arranged the front support 6, but in addition to this, and accordingly the transverse web 27 is also missing the central sleeve 28 which surrounds the cylinder 17 in the embodiment of Figures 3 to 5. In the embodiment of Figure 6 of the set at the upper end of the cylinder 17 transverse web 27 protrudes laterally into the interior of the support 6 and there in a similar manner as the transverse web 27 of the embodiment of Figures 3 to 5 two mutually parallel threaded spindles 29, 30th in which a transverse web 33 having a bearing opening 37 is held vertically adjustable.

In addition, in this embodiment, at the lower end of the two threaded spindles 29, 30, a web-shaped carrier 39 is fixed, in the illustrated embodiment, this support 39 is held on the threaded spindles 29 and 30 by both sides clamped against him nuts 40, 41. On this support 39, two further threaded spindles 42, 43 are set parallel to each other and projecting downwards, by nuts 44 and 45, and these bear a bearing plate 46 with a bearing opening 47, in a similar manner as the also plate-shaped crosspiece 33 is height adjustable. The bearing plate 46 is fixed in a similar manner as the transverse web 33 via two nuts 48, 49 on the threaded spindles 42, 43.

In this embodiment, therefore, the lower bearing assembly, which is formed by the bearing plate 46 and the threaded spindles 42 and 43, not directly fixed to the cylinder of the lifting device, but via the carrier 39 to the threaded spindles 29 and 30 and thus to the upper transverse web 33, and the entire, the lifting arrangement forming is connected solely via the transverse web 27 with the cylinder 17.

Also in this case, both bearing assemblies, namely the transverse web 33 on the one hand and the bearing plate 46 on the other hand independently adjusted continuously in height and set in appropriate positions, so that an adaptation to given dimensions and motor vehicle sizes both in new construction and at a later date can be made at any time.
