Definitions

  • the present disclosure relates to a receiving device with which a support plate of a motor vehicle lifting device can be received at variable heights. At the same time, precise contact of the support plate at a receiving point of a body of a vehicle to be lifted using a lifting platform and/or a jack is made possible, so that safe and rapid raising/lowering can be realized.
  • the present disclosure further includes a lifting device for safely and accurately contacting the pick-up points on the body of a vehicle to be lifted and a method for safely and quickly picking up and/or for safely and quickly lifting a vehicle
  • Hoists generally known from the prior art and designed for raising and lowering vehicles usually include one or more support structures, for example a support arm system that is movable at least in the vertical direction and can be controlled by an integrated control system, as well as a receiving geometry attached to these support structures, which is specifically designed to place the support structure configured for lifting as precisely and tension-free as possible on the vehicle to be lifted, in particular on sections of the vehicle body intended for this purpose.
  • support structures for example a support arm system that is movable at least in the vertical direction and can be controlled by an integrated control system, as well as a receiving geometry attached to these support structures, which is specifically designed to place the support structure configured for lifting as precisely and tension-free as possible on the vehicle to be lifted, in particular on sections of the vehicle body intended for this purpose.
  • an adjustable support plate which has a base plate with four horizontally extending outer projections arranged at the same height.
  • the outer projections engage in recesses in two opposite tabs, which are firmly connected to the support plate and can be moved vertically transversely to the longitudinal axis of the swivel arm.
  • the recesses are shaped in such a way that four stop surfaces are available for the bolt ends at different heights.
  • the height of the support plates, including the head plate and the tabs must be adjusted by hand and from the outset by moving them vertically.
  • Height-adjustable receiving plates are also shown via at least two vertically pivotable scissor levers that intersect and are rotatably connected at the crossing point.
  • a receiving plate is articulated to the scissor lever whose lower end carries out a horizontal displacement during the height adjustment.
  • the height-adjustable receiving plate can be moved vertically using an operating lever and is locked by a pawl.
  • the adjustment handle can be designed together with a shaft leading to the height adjustment device as an axial adjustment device for a multi-part support arm, in which case the shaft is then preferably mounted in an axially guideable manner in a guide bracket. An operator can therefore adjust the support plates to a suitable height without having to reach under the vehicle standing on the ground when the support arms are already swiveled in.
  • the receiving device described here can preferably have a shaft section which is set up to be displaceable in a guide element between a first position and a second position, as well as a support plate receptacle, set up to receive a support plate, which is connected to the shaft section and a guide element, which is designed to guide the shaft section in at least one direction of movement.
  • a support plate is understood to mean a component that is attached, for example, to a lifting platform or a car jack in order to be brought into contact with the manufacturer-specified support points on the underside of the vehicle.
  • These support plates preferably have a circular surface, which is provided with a soft but resistant material such as hard rubber and a correspondingly sized base made of a material such as steel or aluminum, which fits positively into a corresponding receiving device on the base by means of a profile attached to the underside The lifting platform or the car jack is plugged in.
  • the support plate holder claimed here is preferably to be understood as a component that is shaped and suitable for receiving a support plate. Due to its shape, the support plate holder is preferably suitable for accommodating a variety of different support plate models and thus offers a wide range of uses in relation to vehicles from different manufacturers or different model series.
  • the shaft section described here is preferably a metal tube or metal profile whose dimensions and wall thickness are designed to absorb the forces that occur when lifting a vehicle without bending or breaking.
  • another suitable material can also be used.
  • Said support plate receptacle of the present receptacle can be connected to the shaft section of the receptacle described here in various ways.
  • the preferred types of connection include, on the one hand, the provision of a one-piece component that contains both the support plate holder and the shaft section. Such a one-piece component can be produced, for example, by welding the support plate holder to the shaft section or by casting or forging a one-piece metal body.
  • the provision of a variant in which the support plate holder and the shaft section can be detached from one another, for example via a screw connection or the like are connected to the preferred options for establishing a connection between these elements.
  • the guide element is preferably a hollow profile or tube which is closed on the side facing away from the shaft section and is suitable for receiving the shaft section inside.
  • the inner surface of the guide element has the same shape as the outer surface of the shaft section in order to ensure positive guidance of the shaft section in the guide element.
  • the dimensions and wall thicknesses of the guide element are preferably selected so that the elongated shaft section can be displaced in the axial direction in the guide element with a play that is usual for this type of construction in the prior art and is guided by it in its translational movement.
  • the inner surfaces of the guide element can preferably be provided with elements such as bolts or rails in order to enable even more reliable guidance of the movement of the shaft section.
  • slidable layers for example made of hard plastic or the like, can be attached to the inner surfaces of the guide element in order to enable friction-reduced movement of the shaft section within the guide element.
  • a first position describes a position of the shaft portion within the guide element.
  • the shaft section and the guide element partially overlap.
  • the shaft section partially protrudes from the guide section and preferably still has enough overlap area with the guide element to enable reliable and safe guidance of the shaft section.
  • the second position describes a position of the shaft section within the guide element, in which the shaft section is largely sunk into the guide element.
  • the shaft section in order to reach the second position, is preferably pushed further into the guide element starting from the first position up to a mechanical stop and thereby has a larger overlap with the guide element.
  • the device disclosed here has the advantage that in preparation for lifting a vehicle using a lifting platform or a jack, the mounting points on the body of the vehicle can be reached exactly and thus precise and safe positioning of the support plates under the mounting points is possible. This is particularly advantageous if the vehicle to be lifted has an underbody configuration that is very uneven or if the pick-up points are located in troughs or recesses in the vehicle underbody.
  • the claimed item eliminates the need for the use of support plate risers, which are normally used to reach hard-to-reach pick-up points. Accordingly, jack mounts on vehicles with heavily structured underbody or recessed mounts can be contacted more easily and precisely. This enables safe vehicle pickup and vehicle crashes due to poorly positioned support plates can be avoided.
  • the claimed object enables a mechanically stable guidance of the support plate receptacle through the reliable and resilient arrangement of the shaft section in the guide element, since they overlap in a form-fitting manner. This means that no further moving components are required that are subjected to the load of a vehicle to be lifted. Therefore, the claimed holding device represents a low-maintenance, cost-effective and less complex solution compared to conventional support plate increases.
  • the claimed object offers the advantage that there is no change in the position of the support plate holder due to the purely vertical direction change
  • the extension length or the swivel arm geometry can be changed by adjusting the support plate height.
  • a change in position of the support plate relative to the swivel arm and the associated change in geometry of the lifting mechanism of the lift is avoided. This results in a more predictable and easier to handle positioning of the support plates under the mounting points of the body of the vehicle to be lifted.
  • an elastic element which is arranged between the guide element and the shaft section and which is designed to hold the shaft section within the guide section in the first position in the unloaded state, can be provided.
  • the elastic element is preferably arranged between a bottom surface of the hollow profile from which the guide element is made and a bottom surface of the hollow profile from which the shaft section is made. In other words, when the shaft section is displaced into the guide element, the elastic element is compressed between the two mechanical stops formed by the bottom surfaces of the shaft section and the guide element.
  • the elastic element is preferably a metallic spring or an elastomer, but other spring elements with elastic properties such as gas or air chambers can also be used.
  • the spring rate of the elastic element is low in relation to the dead weight of the arrangement of shaft section, support plate receptacle and support plate, in order to ensure that the unloaded shaft section remains in the first position, but at the same time to ensure that the second position can be reached easily by compression of the elastic element make possible.
  • the claimed object is to "scan” the underbody of a vehicle by, for example, moving or pivoting the support plates of a lifting platform with the support plate holder, which can be moved elastically in the vertical direction, in order to reliably contact the recording points on the body of the vehicle to be lifted.
  • the elastic element does not carry the vehicle load and is compressed as far as the stop in the second position when the vehicle is raised.
  • the claimed object therefore offers the advantage of a stable vehicle holder, since a stable support structure is formed at the stop in the second position by the overlap of the shaft section and the guide element on the one hand and support on the bottom surfaces of these parts on the other hand
  • the shaft section can have a first groove for receiving a bolt along its longitudinal axis.
  • the first groove is a groove which extends along the longitudinal axis of the shaft section and runs essentially parallel to the vertical axis of movement of the shaft section and is suitable for receiving a bolt which, when in engagement with the first groove, supports the translational movement of the Shaft section also leads.
  • more than one groove can also be provided in the shaft section.
  • the first groove is particularly preferably a stepped groove and, through its length in conjunction with the aforementioned bolt, defines the mechanical stops of the first position and the second position between which the shaft section can be displaced.
  • first groove can be provided with a sliding insert in order to enable friction-reduced and wear-reduced guidance of the shaft section.
  • the guide element can have a bolt which can be brought into engagement with the first groove of the shaft section.
  • the bolt is a bolt made of metal or another material with high strength, which is located on the inner surface of the guide element and projects into the first groove.
  • the bolt may be fixedly attached to the surface of the inner surface of the guide member, for example by welding, or releasably attached in a hole penetrating the side walls of the guide member to facilitate maintenance work.
  • more than one bolt can also be provided in the guide device.
  • the bolt can be covered with a sliding layer in order to ensure reduced friction and low-wear guidance of the shaft section on the bolt.
  • the shaft section can have a second groove for receiving a spring bolt along its longitudinal axis, wherein the second groove has a recess for receiving a spring bolt.
  • the second groove is a groove which extends along the longitudinal axis of the shaft section and runs essentially parallel to the vertical axis of movement of the shaft section and is suitable for receiving a spring bolt which, when in engagement with the first groove, supports the translational movement of the Shaft section also leads.
  • the second groove is particularly preferably a stepped groove and, through its length in conjunction with the aforementioned spring bolt, defines the mechanical stops of the first position and the second position, between which the shaft section is displaceable.
  • first groove can be provided with a sliding insert in order to enable friction-reduced and wear-reduced guidance of the shaft section.
  • the recess for receiving a spring bolt can particularly preferably be a bore or countersunk bore at the end of the second groove facing the support plate receptacle, into which a spring bolt located on the inner surface of the guide element can snap in order to provide a locking option for the shaft section in the second position.
  • the second groove can be provided with a sliding insert in order to enable friction-reduced and wear-reduced guidance of the shaft section.
  • the first groove and the second groove can particularly preferably be mounted on opposite sides of the shaft section.
  • the guide element can have a spring bolt which can be brought into engagement with the second groove of the shaft section, the spring bolt being designed to snap into the recess for receiving the spring bolt when the shaft section is brought into the second position by compression of the elastic element .
  • a spring bolt is preferably a bolt held in a holder under the pretension of a spring or the like, which can be displaced against the holder using a force directed against the spring.
  • the spring bolt rests on the base surface of the second groove under pretension of the spring and, driven by the spring, penetrates into the recess for receiving the spring bolt when it is reached.
  • Penetration of the spring bolt into the recess for receiving the spring bolt therefore means reaching a releasable locking position of the spring bolt.
  • the spring bolt prevents the shaft section from moving back from the second position towards the first position, driven by the elastic element.
  • the spring bolt can be a component integrated into the wall of the guide element or can be detachably fastened in a recess in the wall of the guide element in order to facilitate maintenance work on the receiving device.
  • the spring bolt can be covered with a sliding layer in order to ensure reduced friction and low-wear guidance of the shaft section on the spring bolt.
  • the spring bolt can be designed to be detachable by hand from its latching position in the recess for receiving the spring bolt.
  • Releasable by hand here means that the spring bolt can be released manually from the latching position, preferably by an operator.
  • the spring bolt can have a handle or a bend that makes it possible to pull it out of the latching position against the preload force of the elastic element and thus enable the movement of the shaft element between the first position and the second position.
  • the previously described arrangement of the spring bolt in conjunction with the second groove offers the advantage of easy operation of the holding device in question. It allows an operator to quickly release the shaft section from the second position. Since the shaft section can be quickly brought back into the first position by the spring force of the elastic element, it is possible to contact the pick-up points of a newly placed vehicle on the lifting platform or jack again easily, quickly and accurately. This means that a large number of vehicles can be recorded within a short period of time productivity, reliability and safety of work processes, for example in a car workshop.
  • a technical advantage is that when the vehicle is lifted, the spring bolt of the holding device always snaps into place, as can be achieved, for example, by the above configuration.
  • the spring bolt can remain in the latching position releasably and permanently (until it is released manually, for example) if it is latched into the recess of the receptacle and thereby holds the shaft section in the second position.
  • the plate remains at the bottom, i.e. in the second position (until it is removed by hand, for example). This means there is no longer any contact with the vehicle and the swivel arm can be rotated outwards under the vehicle without additional effort and the vehicle can be driven off the lifting platform after the lifting process has been completed.
  • a device system based on the integration of the previously described receiving device into a known lifting device is also claimed, which is referred to as a lifting device and is to be distinguished from previously used lifting devices by the equally existing advantages.
  • the lifting device which in this case should be set up equally for picking up a selected vehicle and for raising and lowering the picked-up vehicle about at least one axis, can in this case correspondingly contain at least one vertically movable lifting device for positioning the picked-up vehicle along the above-mentioned, at least one axis , a receiving device attached to the hoist of the lifting device according to at least one of the previously described exemplary embodiments for contacting the support plate with the selected vehicle, so that the lifting device claimed here can be used as a general example of a hoist equipped with the present receiving device.
