Description

[Detailed Description of the Invention] The present invention is a vehicle storage device equipped with a plurality of platforms that can be raised and lowered, and in which the platforms are lowered into a vertical hole below the vehicle running plane when the vehicle is stored. It also relates to a type of vehicle that can be raised to various heights when entering or exiting a vehicle.

Storage devices of this type are known. For example, US Pat. No. 1,781,753 describes such a storage device. By means of a hydraulic cylinder-piston device, a self-rigid elevator-like frame consisting of a number of platforms is raised, and the vehicle can be moved in and out of the platforms depending on the height position of the frame. Furthermore, in the fully lowered state, the surface which coincides with the plane of travel of the motor vehicle can be used as a platform. In this case, no part of the storage device projects upwardly from the vehicle travel plane. The hydraulic system runs along the frame and still requires space below the bottom of the well.

In the containment device described in Austrian Patent No. 227611, the hydraulic lifting device is arranged below the lowerable platform and is therefore placed above the bottom of the shaft by a distance equal to the lifting height. extends downward.

In the storage device described in DE 21 39 743 A1, the guide element partially projects above the vehicle travel plane.

The problem that arises in the first type of garage is that if the vertical hole is formed based solely on the volume required for storing the car, it is not possible to raise the platform below to the plane in which the car is running. That's true. In the fully raised state, the individual guide elements are no longer fully connected and the lifting height that the cylinder-piston arrangement can produce is limited by the maximum height of the cylinder-piston arrangement accommodated in the well. It is slightly less than the total height.

For this purpose, known solutions either make use of the space below the bottom of the well or arrange the guide parts and associated equipment above the vehicle running surface.
However, it is difficult to utilize the space below the bottom of the shaft, especially when the groundwater level reaches the bottom of the shaft. Furthermore, the depth of the vertical hole is also determined depending on the position of the groundwater level. Moreover, even if such difficulties did not arise, it would require considerable expense to form a deeper shaft than is necessary for storing the motor vehicle, just to provide sufficient guidance.

If the guide device or cylinder-piston device is accommodated in a special space, for example in a small-diameter hole (hole) that is additionally formed in the bottom of the vertical hole to match the cross-sectional shape of the guide device or cylinder-piston device, repair is not required. The operation is extremely difficult due to the difficulty of accessing the guide device parts or the cylinder-piston device parts located in the small-diameter bore.

Protruding parts of the device above the vehicle running surface is only permissible if this does not pose an obstacle. The advantage of such underground garages is that they allow the underground space to be used without interfering with the vehicle running surface.

The aim of the invention is to allow all enclosure parts to be accommodated within the well itself, thus simplifying repair and assembly operations.

In order to achieve this purpose, the configuration of the present invention includes:
In a storage device of the first-mentioned type, at least one guide device consisting of three parts is arranged in the well, the parts being telescopically movable relative to each other, the first part being fixedly coupled to the well, the second member being movable relative to the first member by means of a cylinder-piston arrangement, and the third member being fixedly connected between the second and third members. The cylinder-piston arrangement is supported by a cylinder-piston device which allows movement relative to the second member.

It has now been found that the device according to the invention solves the above problems in a surprisingly simple manner.
By using a guide consisting of two parts, a cylinder-piston arrangement of comparatively simple construction is sufficient. The cylinder-piston arrangement only needs to have a length somewhat greater than half the depth of the well. The guide or the cylinder-piston arrangement can therefore be easily accommodated in the well itself, without the need for additional holes in the bottom of the well, and repair work is easily carried out due to the easy access to the accommodated and assembled guide or cylinder-piston arrangement. The length of the individual parts of the guide and the guide lengths for guiding the individual parts relative to one another can also be significantly shorter than the depth of the well. It is therefore not necessary to form recesses in the well, which would entail additional costs and make assembly or repair difficult. Nevertheless, the arrangement according to the invention can achieve a comparatively large lift height; the required space for three cars one above the other is approximately 5 m, and therefore the maximum height of the parking device in the raised position is approximately 10 m.
It is clear that with a certain weight acting on it, considerable forces will be generated and therefore reliable guidance is essential. This device solves this problem in a simple manner.

A significant advantage of the present invention is that expensive telescoping cylinders are avoided. A simple single-acting cylinder can be used. In some cases, it is also possible to work with cylinders connected in parallel.

Although the invention uses two cylinder-piston arrangements that are not drivingly connected to each other to drive the members of the guide device, no unwanted relative movements occur. In this case, it is not necessary to use special control devices such as dosing mechanisms or other similar means. The cylinder-piston device of the guide device can be easily connected to the pump.
For correct operation of the storage device, it is perfectly possible for one or the other cylinder-piston device to be extended first due to the different friction between the individual parts of the guide device. The particular position of the second part as intermediate piece is not critical for correct functioning.

In a preferred embodiment, the device according to the invention cooperates with an upper platform or cover plate, which closes the longitudinal hole and forms another space for the motor vehicle or serves as a running surface. In this way, the device according to the invention can also be placed on narrow access roads. This is because in this case the access road is only briefly interrupted when vehicles enter and exit the individual platforms.

As a rule, one guide device is arranged on each side of the liftable platform, the uppermost parts of these guide devices being preferably arranged below the cover plate. They are connected to each other by reinforcing cross members.
However, the invention can also be applied when the platform accommodates more than one vehicle.
If the platform is wide enough to accommodate more than one motor vehicle, it is also possible to arrange the guide device in the central area of the platform.

The number of platforms that can be raised and lowered is not critical to the invention. Storage devices can also be constructed according to the invention with only one platform that can be lowered into the well and a further platform forming the cover plate.

In the following, the structure of the present invention will be specifically explained with reference to embodiments shown in the drawings.

FIG. 1 shows an apparatus for storing a plurality of automobiles one above the other according to the present invention, which has the following features:
It has platforms 4, 5, 6 and 7 which can be lowered into the vertical hole 8 at the position shown in FIG. The platforms 4 to 7 are all fixed to the member 3 of the guide device 9 and have a constant mutual spacing in the illustrated embodiment.

In the lowered position, the upper platform 7 is adapted to close the opening of the vertical hole;
It rests on the step 10 of the opening. In short, the upper platform 7 is narrower than the vertical hole 8, as seen in FIG.
It is somewhat wider than the In the illustrated embodiment, platforms 4 to 6 each have a balustrade 11.
However, this is not necessary, and the vehicle may be allowed to pass over the elevated platforms 4-6.

As can be seen in FIG. 3, the guide device 9, which is arranged on each side of the platform, has parts 1, 2 and 3. Each member is configured in a box shape. As can be seen from FIG. 6, the inner member 1 forms a closed box-shaped member, and the member 2
partially surrounds this, and through the open side of the part 2 the part 1 is connected to the well wall 13 by a connection 12 .

The member 3 is also box-shaped. Sliders 14 are provided between members 1 and 2 and between members 2 and 3, and these sliders are connected to guide rails 1 provided on the outer surfaces of members 1 and 2.
Guided by 5. Instead of guide rails and slides, other suitable guide mechanisms may be used.

As shown in FIG. 1, the member 1 rests with its feet 16 on the bottom 17 of the vertical hole. A cylinder piston device 18, which is provided parallel to the member 1, has its lower end supported by the foot 16, and its upper end is attached to a support block 19 provided on the outer surface of the member 2. There is. In FIG. 6, this support block 19 is indicated by a dash-dot line.

Support block 20 provided at the lower end of member 2
A further cylinder-piston arrangement 22 is mounted between the support block 21 and the support block 21 provided near the upper end of the member 3. A notch (not shown) is formed in the lower end of the member 3 for the support block 20, which allows the member 3 to
It can be lowered to the lower position shown in the figure.

In the illustrated embodiment, the cylinder-piston arrangements 18 and 22 each consist of two cylinder units arranged parallel to one another. This type of construction makes it possible to minimize the clearance between the platform and the well wall 13. However, it is also possible to design each cylinder-piston arrangement as a single cylinder unit. In any case, it is advantageous for the cylinder-piston arrangements 18 and 22 to have the same construction. There is no need to use a telescoping cylinder.

However, since the extended length of the cylinder-piston devices 18 and 22 is quite large, a support member 23 is provided for the cylinder-piston device 18 at the lower end of the member 2, which slides along each side of the cylinder-piston device 18; A similar support element can also be provided for the cylinder-piston arrangement 22 at the lower end of the part 3. These support members serve as additional guidance and reinforce the cylinder-piston arrangement.

As can be seen in FIG. 5, the upper ends of the parts 3 are connected to each other by crosspieces 24. In this case, the crosspiece 24 is connected to the part 3 by corner reinforcements 25. The crosspiece 24 actually partially projects into the upper platform 7 and is also connected to this platform. In this way, the parts 3 of both guide devices 9 are rigidly connected to each other, and the movement of the guide devices is extremely stable.

When using the storage device, all cylinder piston devices 18 and 2 can be removed, for example in the condition shown in FIG.
A pressure medium source is connected to 2. In particular, no expensive dispensing equipment is required. Due to the rigid connection of the parts 3 on both sides to one another, during the upward movement both guide devices 9 move in the same manner and no clamping or jamming phenomena occur.

Also, no special distribution device for the pressure medium is required between the cylinder-piston devices 18 and 22 on one side. If the friction is slight, the cylinder-piston arrangement 18 will generally have to overcome a greater resistance due to the additional load exerted by the member 3 and the cylinder-piston arrangement 22, so that the cylinder-piston arrangement 18 is first 22 reaches maximum extension. Next, the cylinder piston device 18
moves the part 2 together with the already raised part 3 and the associated equipment, so that the desired raised position is achieved.

A predetermined raised position is automatically produced by an electrohydraulic device having a push button of known construction;
The platform 4, 5 or 6 can be aligned with the road surface.

The safety devices that secure a specific lifting position, in particular the locking bolts integrated in the hydraulic circuit, are not shown in the drawings, but when the cylinder-piston device is loaded, the safety devices are unlocked and As a result, an upward or downward movement is possible, and locking takes place when the hydraulic device is finally severed.

In the exemplary embodiment shown, the individual platforms are rigidly fixed to the part 3, so that the mutual spacing of the individual platforms 4 to 7, i.e. the height of the storage space, remains unchanged. However, in the present invention, the mutual spacing of the platforms is made variable;
For example, it is also possible to provide individual platforms 4, 5 or 6 movable along the member 3. For example, each platform 4, 5 or 6 can be guided along the member 3 by a special slide, and each individual slide or platform can be suspended on a platform or slide arranged above it. I can do it. In this case, the distance between the individual platforms can be maximized in the raised position and minimized in the lowered position (rest position).

It is also possible to increase only the height of a particular storage space so that a motor vehicle can freely drive through this storage space.

The means for increasing or changing the mutual spacing of the platforms are not shown in the drawings, but can also be implemented easily.

As is clear from FIG. 2, the lifting height can be simply increased by increasing the extension distance of the cylinder-piston arrangement.

In the illustrated embodiment, individual platforms 4,
5 or 6 is rigidly connected to the member 3 and secured in a horizontal state by a stay 27.

In special cases, it is also possible to arrange the platforms at an angle with respect to the member 3 of the guide device, or to design certain or all platforms to be tiltable.
