Description

Technical field

The present invention relates to a device for lifting vehicles according to the preamble of claim 1.

State of the art

According to the prior art, simple ramps for loading or for the purpose of repairs are sufficiently known. Ramps for exhibition purposes, for skill exercises and various rocking ramp constructions are also known. The pamphlets GB 2134482 B , WO 9806658 A1 , CH 19620013217 A , GB 2306939 A , GB 2257411 A , US 4238114 A , DE955812 C show some exemplary versions. Specifically from the published patent application GB 2 047 196 A a ramp-like support surface is known, which comprises one or more rails, which are spaced above the rails by means of a frame and pivot and support points arranged on an axis of rotation from a tilted position in which the vehicle can be moved onto the rails into a horizontal position are pivotable. The pivoting movement of this device is automatically caused by the movement of the vehicle on and off the rails.

A disadvantage of the ramps known from the prior art is the need to move the vehicle into a new position on the ramp each time in order to use the tilting function and to make another part of the vehicle accessible.

Another disadvantage is the fact that manual operation is hardly possible for a single person alone, or that power-operated drives are required for use. In addition, known constructions have limited application possibilities due to their considerable size and the associated high weight, which results in inflexibility, immobility and high space requirements, especially in times of non-use.

Presentation of the invention

The present invention has for its object to provide a device which eliminates the aforementioned problems and which is suitable for moving a vehicle quickly, in the smallest space, as an individual, manually or power-operated, to the most practical position and height, where Repairs, loading or a presentation are possible without having to reposition the vehicle several times on the device. In order to reach the different positions of the device and thus of the vehicle, the position of the vehicle on the rocker itself should not have to be changed again. The lifting and lowering of the device should be sufficient, preferably by hand or, if desired, also supported by a power drive. The aim of the present invention is to create a very light device which can be moved and transported by muscle power only by one person.

According to the invention, the above object is achieved in accordance with the preamble of claim 1 in conjunction with the characterizing features. Advantageous refinements and developments of the device according to the invention are specified in the dependent subclaims.

The device according to the invention for lifting vehicles comprises a ramp-like support surface which comprises at least one rail, the rail being spaced apart by means of a frame via at least one below and on at least one The axis of rotation and the point of rotation arranged from a tilted position, in which the vehicle can be moved onto the rail, can be pivoted into a horizontal position, wherein at least two axes of rotation, each with at least one point of rotation and support, are provided below the rail and the axes of rotation in the longitudinal direction the rail is arranged at a distance such that the device can be pivoted on one of the at least two axes of rotation depending on the tilt position,

According to the invention, a device according to the preamble of claim 1 is characterized in that at least one further pivot and support point arranged on the frame so as to be displaceable and / or displaceable is provided to create an at least third axis of rotation, the at least one pivot and support point comprising a plug-in module , by means of which the pivot and support point can be adapted to different vehicles.

The invention thus achieves the object by means of a lever-like or rocker-like rail construction which can be used in a multifunctional manner due to a preferably light, compact, mobile and one-part or multi-part and stackable design. This can be done by a single person, e.g. an average adult, can be set up and operated in just a few minutes using muscle power alone to get a vehicle to a comfortable working height.

As soon as the vehicle is in the ideal position on the support surface and the optimal weight distribution on the front and rear part of the device is achieved, the tilting movement can take place via the various pivot points. These are preferably arranged in such a way that only a minimal amount of force is required relative to the mass of the vehicle in order to raise or lower the rocker on one side.

At the same time, the pivot points are selected so that the entire construction, including the vehicle, remains stable and automatically rests in one of the three basic positions.

In order to be able to tilt vehicles with differently high centers of gravity or mass equally easily, at least one further pivot and / or displaceably arranged on the frame and / or displaceably arranged pivot point and support point, which is also the first pivot point that is alone in this position, can be created to create an at least third axis of rotation touches the ground, be provided. Designed as a plug-in module, the first pivot point can be adapted directly to different vehicles. The higher the center of gravity and / or the higher the mass, the further apart the pivot points should be positioned.

If the device is tilted from the opening position into the horizontal, this is done via two or more pivot points. If the rocker is tilted further, this is also done via at least two other pivot points.

The pivot point moves relative to the center of gravity, depending on the tilt position of the rocker, forwards or backwards. The pivot points used relative to the center of gravity / mass of the vehicle are then set in such a way that the forces to be applied for tipping are minimized. This tilting movement can be carried out manually or by power from both ends of the rocker.

The advantages of the described device lie in the fact that a vehicle once positioned at the balanced position does not have to be moved again and can be tilted into any desired position by one person using muscle strength alone. By simply repositioning the plug-in module described, the device can be adapted directly to different vehicles. This is not possible with any previously known device. This allows access to the vehicle parts, which are otherwise difficult or impossible to access, such as the underbody, with the least amount of effort that is otherwise only possible with a lifting platform or pit. Furthermore, the device is characterized by a compact Packable, mobile, light, multi-part, stackable and multifunctional design.

A single person can put together the desired seesaw shape in just a few minutes and move a vehicle to a comfortable working height.

Implementation of the invention

Like from the Fig. 1 and 2a, 2b, 2c, 2d As can be seen, the device 1 according to the invention for lifting vehicles 2 is formed from a ramp-like support surface 10 which comprises at least one rail 100. The rail 100 is spaced above the rail 100 by means of a frame 11 and pivot and support points 13, 13a arranged on the axes of rotation 12, 12a and a further pivot and support point arranged on the axis 11 and displaceable on an axis of rotation 12b 13b can be pivoted from a tilted position, in which the vehicle 2 can be moved onto the rail 100, into a horizontal position.

The at least one rail 100 is preferably of multiple parts, each part 1000, 1001 each comprising at least one pivot and support point 13, 13a.

The parts 1000, 1001 are reversible by means of connecting means 102 and particularly preferably can be connected at an angle to one another or to one another.

At least one stop 15 for a vehicle 2 is preferably provided on the rail 100 and can be arranged or arranged such that the weight distribution of the vehicle 2 on the front and rear region of the rail 100, based on the pivot and support points 13, 13a, 13b13c is almost balanced.

In a further embodiment of the invention, sensors are also preferably provided which are designed to detect the weight distribution of the vehicle 2 on the at least one rail 100.

Different configurations of the device 1 can be put together using different plug adapters. The various devices 1 can also be used independently and independently of one another for the driveway. The occasional user can stack the parts 1000, 1001 of the device 1 into one another after use and thus stow them in a small space.

Application description

After correct alignment of the two lanes (or two devices 1 aligned in parallel), the vehicle 2 is driven onto the two devices 1 until the desired stop. The stop 15 for the front wheels is selected so that the ideal standing position results for a specific vehicle 2. This is achieved when the weight distribution on the front and rear part of the respective device 1, based on the pivot and support points 13, 13a, 13b, 13c, is almost balanced. The arrangement of the two devices 1 is adapted to the track width of the vehicle 2 and secured with a spacer.

The position of the stop 15 is determined when the vehicle 2 is approached by approaching the balance point, which is also supported by technical aids such as e.g. Weight sensors or signal transmitters can be determined. This process only has to be carried out once for a specific vehicle if the vehicle-specific position of the stop 15 is marked accordingly. The vehicle 2 could also be pulled onto the device 1 by means of a winch. By means of brake wedges, the vehicle 2 is then secured in the optimal position on the device 1 in addition to its own brake.

In the position balanced in this way, the front part of the vehicle 2 is now approximately at the head height of an average-sized person, the rear part near the ground level. The device 1 now has several pivot and support points 13, 13a, 13b, 13c via which the User can change the position of the device 1 with his muscle strength. Since the vehicle 2 is almost level and itself has a high mass, this happens slowly due to physical reasons (inertia), so there are no abrupt, uncontrolled or surprising movements of the construction together with the vehicle 2.

To prevent the rocker from moving unintentionally during use, e.g. during assembly work on the vehicle, the respective position is secured with two supports 14 hanging downwards. These end just above the floor level so that they can also be removed if necessary.

Fig. 3 shows the plug-in module 130 in different positions for vehicles of different sizes, wherein the pivot point 13b can be adjusted by means of a support body 132 which can be reversibly arranged on the plug-in module 130 by means of bolts 131 or the like.

The device 1 according to the invention is not limited in its embodiment to the preferred embodiments specified above. Rather, a large number of design variations are conceivable, which make use of the solution shown even when the design is fundamentally different.
