    Lift support with multiple outriggers Field of the Invention
    The present invention relates to a vehicle with a mounted lift system, wherein the lift system comprises a lift part and a lift support. The lift support is connected to the lift part, via a lift pedestal and is used to support the vehicle while lifting the lift part.
    The present invention further relates to a lift system and a lift support.
    Background of the Invention
    Lift systems are a secure means for fulfilling tasks such as windows cleaning, putting up placards in high places such as lamp posts as well as taking them down again. The lift systems can be mounted on vehicles in order for them to be easily transported from one place to another.
    The weight of the lift system is considerable in relation to the weight of the vehicle, which is why the lift system is normally provided with a lift support in order to prevent damage to the car as well as to improve the safety of using the lift.
    The lift support is commonly arranged under the vehicle comprising two outriggers, which are adapted for engagement with the ground in order for the forces from the lift to be transmitted at least partially through the outriggers and not through the vehicle. Hereby, damage to the vehicle is prevented.
    The two outriggers below 'the vehicle are arranged along the same axis but in opposite directions. The outriggers are moved in a singular movement outwards and downwards from their raised position until they reach the ground.
    The actual support and balance provided by the lift support is highly dependent upon the design of the lift support.
    Object of the Invention
    It is the object of the present invention to provide a vehicle mounted with a lift system, where the lift support of the lift system is optimized in order to achieve a high level of safety when using the lift system.
    Description of the Invention
    This object is achieved by a vehicle with a mounted lift system, the lift system comprises a lift part and a lift support, the lift support is connected to the lift part via a pedestal lift and being used to support the vehicle while lifting the lift part characterized in that the lift support is mounted at a mounting point centrally below said vehicle and comprises outriggers extending along at least two different axes and the outriggers through endpoints are adapted to support the lift part, against the ground and thereby rigging the vehicle with the mounted lift system to the ground whereby the forces from the lift pedestal are distributed to the outriggers.
    By vehicle is meant any vehicle such as cars, trucks, vans etc.
    In one embodiment, the vehicle is a van having a weight between 3.5 and 5 tons, such as an MB sprinter and VW Crafter.
    When the lift system is mounted on a vehicle the lift pedestal is arranged through the roof of the vehicle and down towards the floor of the cars, where the lift pedestal is connected to the lift support. Above the roof of the vehicle the lift part is connected to the lift pedestal.
    Advantageously, the lift pedestal is mounted to the center of the lift support at a mounting point. The forces from the lift part of the lift system are lead down through, the pedestal into the lift support. From the center of the lift support the load is distributed to the outriggers of the lift support. The outriggers are mounted close to the mounting point, which leads the load directly down to the outriggers. Hereby, the load is at least partially removed from the vehicle itself thereby preventing damage to the vehicle.
    Furthermore, since the lift support is mounted centrally under the car the load is also better distributed as well as the balance of the vehicle can be maintained during use of the lift system.
    When the lift system is in use, the lift support is activated by moving the outriggers to a position where their endpoints are arranged on the ground. During this process the vehicle is further lifted to a small degree without the tires of the vehicle being lifted, from the ground. Hereby, the load from the lift part is mainly directed via the lift pedestal into the lift support, which due to its design distributes the load into the outriggers.
    The outriggers are arranged along at least different axes in order for the load to be sufficiently distributed. Furthermore, the balance of the system is improved by having the outriggers arranged along at least two different axes instead of only one axes as is commonly known from the prior art. Thus, if the lift part is moved sufficiently far from the vehicle with a lift support having outriggers along one axis alone, there is a risk that the balance of the system is impaired and that the vehicle could be damaged or even tipped over. However, if the outriggers are arranged along at least two different axes the lift support is not as easily tipped and thus, the balance of the lift system is improved. Furthermore, this means that having outriggers along at least two different axes would enable the lift part to be able to function safely at a wider distance from the vehicle.
    By at least two different axes is to be understood two, three, four, five, six, seven etc. axes. In one embodiment the angles between two different axes is a side angle below 90 degrees towards the sides of the vehicle and a front angle above 90 degrees towards the front and back of the vehicle, in one embodiment the side angle is around 60 degrees, preferably 64 degrees and the front angle is 120 degrees, preferably 116 degrees.
    The at least two different axes can be arranged parallel to one another, perpendicular to one another or at any angle therein.
    In a further embodiment, the outriggers are designed having a slim design obtained in order for the outriggers to take up as little space as possible beneath the vehicle. The design is balanced between ability to withstand considerable force and a design taking up only a minimum of space. The slim design is beneficial since it enables the outriggers to be arranged under a multiplicity of different types and models of vehicles. Furthermore, the slim design prevents the outriggers from hitting bumps on the road and hereby being damaged.
    In a further advantageous embodiment, the lift support comprises four outriggers extending in different directions from said mounting point. Hereby, a stable foot is formed by the four outriggers providing the lift system with excellent balance and distribution of the force from the load of the lift part and the lift pedestal.
    In one embodiment, the four outriggers are arranged along two different axes arranged perpendicular to one another. Thus, the four outriggers are arranged having and angle of 90 degrees between each other.
    In a further advantageous embodiment, each outrigger can be changed in a longitudinal direction of the outrigger hereby the length of the outriggers and thereby the distance between mounting point and endpoints are being changed. Hereby, the outriggers are moved in a single direction and thus, moved substantially parallel to the ground. This is in contrast to the prior art, where the outriggers are moved in a slanting direction. Moving the outriggers in the longitudinal direction at first before lowering the endpoints to the ground means that the outriggers can be elongated to different lengths depending on the given place of parking as well as the load to be carried by the lift part. Furthermore, the outriggers can easily be moved over obstacles such as pedestrian edges.
    It is understood the individual outriggers can be elongated to individual length depending on the need and the possibility.
    This movement can be introduced by the means of push-out cylinders e.g. a hydraulic cylinder.
    In one embodiment, the push-out cylinders are thin cylinders in order for the movement to be fixed.
    In a further embodiment, the outrigger is arranged at an upward angle with respect to the ground i.e. the endpoint of the outrigger is distantly higher above the ground than the part of the outrigger close to the mounting point. This means that when the outrigger is moved in the longitudinal direction it is able to easily cross obstacles such as bumps and pedestrian edges if these were higher above the ground than the mounting point.
    In a further embodiment, the outriggers are mounted with a control system controlling the movement of the outriggers in the longitudinal direction. As an example, the control system could control the movement in relation to walls moving the outrigger only to a position close to the wall and not into the wall.
    In a further advantageous embodiment, each outrigger can be moved in a direction substantially perpendicular to the longitudinal direction of the outrigger, whereby the endpoints can be moved toward the ground or away from the ground. Hereby, the endpoints of the outrigger engage with the ground and are stably arranged on the ground.
    In one embodiment, the movement is performed by a push-down cylinder such as a hydraulic cylinder.
    In a further embodiment, the movement of the outriggers can be individually controlled. Thus, one outrigger is moved further down than others of the outriggers. This is advantageous in connection with the lift support to be arranged on bumpy road or close to a pedestrian. Hence, the outrigger to be arranged on the pedestrian is not to be moved as far as the outrigger to be arranged on the ground, since the pedestrian is at a higher level.
    In a further embodiment, the movement towards the ground is controlled by a control system, which automatically detects the necessary movement of each outrigger for the outrigger to be adequately arranged on the ground in order to provide sufficient load distribution and balance to the lift system.
    In a further advantageous embodiment, the outriggers are rotatably mounted to the vehicle, whereby the position of each outrigger can be changed in relation to the vehicle, Hereby, the exact position of the outriggers can be determined when the lift support is to be used. Thus, the outriggers can be arranged on the ground which is sufficiently firm for stability to be obtained and for enabling sufficient load distribution.
    In one embodiment, the position between the individual outriggers is maintained, while the outriggers as such are rotated.
    In another embodiment, the position between the individual outriggers can be changed while rotating one or more of the outriggers.
    In a further advantageous embodiment, the lift support further comprises at least one floor loading plate, where the at least one floor loading plate forms a sandwich structure with a subframe and the chassis frame of the vehicle. Hereby, the lift support can be attached thoroughly to the vehicle increasing the stability of mounting of the lift system and thus the safety of using the lift part.
    The subframe is bolted to the floor loading plates around the chassis of the vehicle forming a sandwich structure. Hereby, the chassis of the vehicle does not have to carry any load from the lift.
    Furthermore, by using floor loading plates the bottom of the vehicle is maintained on the lane. Thus, the back of the vehicle can also easily be used for storage.
    In a further advantageous embodiment, the outriggers are mounted onto the subframe.
    This invention further describes a lift system for mounting in a vehicle, wherein the lift system comprises a lift part and a lift support, the lift support is connected to the lift part via a lift pedestal and being used to support the vehicle while lifting the lift Partly characterized in that the lift support is adapted to be mounted at a mounting point centrally below said vehicle and comprises outriggers extending along two different axes and the outriggers via endpoints are adapted to support the lift part against the ground and thereby rigging the vehicle with the mounted lift system to the ground whereby the forces from the lift pedestal are distributed to the outriggers.
    This invention further describes a lift support connected to a lift part via a lift pedestal to form a lift system, which can be mounted on a vehicle and used to support the vehicle while lifting the lift part characterized in that the lift support comprises a subframe for being mounted to the chassis of a vehicle and outriggers being mounted to the subframe, where the outriggers extend along at least two different axes and the outriggers comprise endpoints, the endpoints being adapted to support the lift system against the ground.
    The lift system includes a lift part and a lift support. The lift part is the part of the lift system with the enclosure for the person to be lifted as well as the arm for moving the enclosure into the air.
    The lift part is connected to the lift support via a lift pedestal. The lift pedestal distributes the load from the lift part directly to the lift support.
    The lift support is the part of the lift system supporting the lift part and ensuring that the enclosure can be safely lifted above the ground. It is thus important that the lift support is constructed in a manner whereby the balance of the lift system can be maintained even in the most distant positions of the enclosure. The lift support can arrange outriggers in order to maintain the balance and to distribute the heavy load of the arm and the closure. In order to achieve the most optimal balance and load distribution even in the most distant position, the outriggers of this lift system are extended along at least two different axes.
    By at least two different axes is to be understood two, three, four, five, six, seven etc. axes.
    The at least two different axes can be arranged parallel to one another, perpendicular to one another or at any angle therein.
    In a further advantageous embodiment, the lift support further comprises at least one floor loading plate. The at least one floor loading plate is attached to the subframe of the lift support opposite of the outriggers. Hereby, the at least one floor loading plate supports the structure of the subframe and prevents the subframe from col lapsing due to the load of the lift part when this is connected via the lift pedestal.
    In a still further advantageous embodiment, the outriggers are rotatably mounted to the subframe. Hereby, the exact position of the outriggers can be determined when the lift support is to be used. Thus, the outriggers can be arranged on the ground which is sufficiently firm for stability to be obtained and for enabling sufficient load distribution.
    In one embodiment, the position between the individual outriggers is maintained, while the outriggers as such are rotated.
    In another embodiment, the position between the individual outriggers can be changed while rotating one or more of the outriggers.

    Detailed Description of the Invention
    Figure I illustrates a lift support 101 known in the art. The lift support comprises a subframe 103, two outriggers 105a, b connected to one end of subframe 103 at a mounting point 107. The two outriggers 105a, b are arranged on one axis but in opposite directions.
    The outriggers 105a, b comprise endpoints 109a, b which are arranged on the ground when the lift support 101 is activated for use. In order to do so the outriggers 105a, b are moved in a slanting movement by means of the cylinders 11a, b outwards and downwards until the endpoints! 09a, h are arranged onto the ground.
    Figure 2 illustrates an embodiment of a lift support 201 according to this invention. The lift support 201 is connected to a lift pedestal 213 at a mounting point for the lift pedestal 215. The lift pedestal 213 is at the other end connected to the lift part (not shown).
    The lift support 201 comprises a subframe 203 having a longitudinal part 217 and a transverse part 219.
    Below the lift support 201 four outriggers 205a, b, c, d (d not shown) is mounted centrally under the subframe 203. The outriggers 2G5a, b, c, d include endpoints 209a, b, e, d for engagement with the ground, when the outriggers 2Q5a, b, c, d are moved low ards the ground by means of push-down cylinders 221, further, the support lift 201 comprises a rotating pin 229 for allowing the outriggers 205a, b, c, d to be moved towards the ground by means of the push-down cylinders 221. Each outrigger 205a, b, c, d is provided with a push-down cylinder 221.
    In this embodiment, the endpoints 209a, b, c, d comprise a circular foot to enable a stable engagement with the ground.
    The outriggers 205a, b, c, d each further comprise a push-out cylinder 223 for movement of the outrigger 205a, b, c, d in the longitudinal direction i.e. for changing the length of the outrigger 205a, h, c, d. The push-out cylinder 223 is arranged in the inner part of the outrigger 205a, b, c, d.
    The outriggers 205a, b, c, d. are arranged along two different axes. In this embodiment, the two different axes are substantially perpendicular to one another. Two outriggers 205a, c are arranged along a first axis with their endpoints 209a, c being in opposite directions. The remaining two outriggers 205b, are arranged along a second axis with their endpoints 209b, d being in opposite directions. Hereby, the load of the lift part is distributed in four different directions. Furthermore, the load on each of the outriggers 2G5a, b, c, d is less than when the number of outriggers 205a, b, c, d is less e.g. two. In addition, the outriggers 205a, b, c, d form a cross by their axes being substantially perpendicular. Thus, a better balance of the lift support 201 is obtained than if the outriggers are arranged along a single axis.
    Above the subframe 203, a floor loading plate 225 is attached. The floor loading plate 225 among other things prevents the subframe 203 from bending due to the U-structures 227 of the subframe 203. Thus, the floor loading plate 225 strengthens the lift support 201.
    Figures 3A-3C illustrate different views of a lift support 201 as described and illustrated in Figure 2 but without the attachment of the lift pedestal 213. The numbers and elements as described above for Figure 2 thus correspond to those described and illustrated in Figures 3A- 3C.
    Since the lift pedestal 213 is not connected to the lift support in Figures 3A-3C, the mounting points for the lift pedestal 215 can be seen.
    Figure 3B furthermore illustrates the directions of the movements of the push-down cylinder 221 and the push-out cylinder 223. The push-out cylinder 223 moves the outriggers 205a, b, c, d in a longitudinal direction 231 before the push-down cylinder 221 moves the outriggers 205a, b, c, d in a direction 233 substantially perpendicular to the longitudinal direction 231 whereby the endpoints 209a, b, c, d of the outriggers 205a, b, c, d are moved toward the ground.
    Figure 3B further illustrates additional details with regard to the push-down cylinder 221. This cylinder 221 is attached to the subframe 203 in a rotating point 235 and is further mounted inside the outrigger 237. Hereby, the downward movement of the outrigger 2G5a, b , c, d by push-down cylinder 221 is enabled.
    In addition, the side view illustration of figure 3B shows the mounting point 207 for the outriggers 2Q5a, b, e, d.
