Definitions

  • the invention relates to stands for recreational vehicles; specifically, to au- tomated lifting stands for recreational vehicles.
  • an operator e.g., a mechanic or an individual
  • it is hard and tiring for one person to perform such an operation because he must stand, hold the motorcycle's rear with one arm and, at the same time, use the other arm to push the stand under the motorcycle, thus risking dropping a motorcycle that weights several hundred kilos. So, such stands are unsuitable to be handled by one individual.
  • Other types of stands enable lifting the motorcycle manually (e.g., with a hand crank), electrically or hydraulically (e.g., with a foot pump).
  • the stand is first bolted to the spools of the motorcycle's rear wheel assembly before lifting the motorcycle, which is a very time consuming process. In general, all the available stands are unstable when the motorcycle is finally in place up on them.
  • the first aspect of the invention is to provide an improvement to the state-of-the-art.
  • the second aspect of the invention is to solve the aforementioned drawbacks of the state-of-the-art solutions by providing: (i) a stand that enables a single person to perform the lifting operation; (ii) a stand that speeds up the overall lifting operation; and (iii) a stand that is stable when the vehicle is finally lifted.
  • the third aspect of the invention is to provide a universal stand, which can be used for any type and size recrea- tional vehicle. Description of the invention
  • an automated lifting stand for a recreational vehicle wherein the stand comprises a frame including an upright portion, two arm units and a linear actuator, wherein the arm units at one end are coupled to the linear actuator and are adapted to pivot about a pivoting point at the upright portion of the frame when the linear actuator extends/contracts, wherein each arm unit at another end comprises a spool receiver including a spool receiving portion adapted to receive a spool of a vehicle's wheel assembly such that, when the free ends of the arm units rise, the vehicle is lifted when each spool receiving portion meets the spool of the vehicle's wheel assembly (for example, in case of an ATV, the spool receiving portion of one arm unit is adapted to receive the outward-facing spool of one of the rear/front wheel assemblies and the spool receiving portion of the other arm unit is adapted to receive the outward-facing spool of the other rear/front wheel assembly).
  • the invention relates to stands for, e.g., parking or
  • a linear actuator embraces: mechanical actuators, hydraulic actuators, pneu- matic actuators, piezoelectric actuators, electro-mechanical actuators, linear motors, telescoping linear actuators, etc.
  • a spool also embraces a spool-shaped adapter, in case the vehicle does not have spools and adapters having a spool-like shape are attached to the vehicle's front/rear wheel assemblies.
  • the invention has the advantage that the lifting is performed in an automated manner and does not require prior bolting of the vehicle to the stand. Consequently, the operation can be easily performed by a single person (e.g., in a workshop or outdoors) and in a much shorter time.
  • the stand further comprises a coupling structure and an axle shaft, wherein the coupling structure is connected at one end to the linear actuator and at another end to the axle shaft, wherein the arm units are fastened to the axle shaft so that the extension/contraction of the linear actuator makes the coupling structure swing and consequently the arm units pivot about the pivoting point at the axle shaft.
  • the coupling structure is U-shaped, the base of the U-shaped coupling structure being connected to the linear actuator and each free-end of the U-shaped coupling structure being connected outwardly to one axle shaft, wherein each arm unit is fastened to one axle shaft so that the extension/contraction of the linear actuator makes the U-shaped coupling structure swing and consequently the arm units pivot about the pivoting point at the respective axle shafts.
  • the U-shaped coupling structure (also referred to as a wheel clearance cradle) has the further advantages of (i) avoiding that the stand twists when the vehicle is lifted; and (ii) enabling and easing the removal of the vehicle's rear/front wheel in case of performing maintenance operations to the vehicle once in place up on the stand.
  • the frame further includes a base portion and the stand further comprises a first trigger switch fastened at the base portion of the frame, so that, when the vehicle's wheel touches the first trigger switch, the linear actuator activates, thereby raising the free ends of the arm units and consequently the vehicle.
  • This embodiment has the advantage of providing a mechanism for automatically triggering the activation of the lifting operation.
  • the first trigger switch is movable along a longitudinal axis, so that the spool receiving portions are always able to receive the spools of the vehicle's wheel assembly regardless the wheel's diameter.
  • a screw may be loosen/tightened in order to move the first trigger switch in and out along the longitudinal axis.
  • the arm units are movable along the axle shaft, so that the distance between the arm units is adjustable according to the wheel's width (e.g., 110-180 mm tires).
  • each arm unit is movable along the respective axle shaft, so that the distance between the arm units is adjustable according to the wheel's width.
  • one or more bolts may be loosen/tightened in order to move the arm units inwardly/outwardly along the axle shaft(s).
  • the above embodiments have the advantage of providing a universal stand, which can be used for any type and size recreational vehicle, also produced by different manufacturers.
  • the state-of-the-art solutions require specific adaptors for ena- bling the stand to suit different recreational vehicles.
  • the base portion of the frame is U- shaped and comprises an inner wheel guidance portion shaped so as to guide the vehicle's wheel in position.
  • This embodiment has the advantage of easing the operator's manoeuvre when positioning the vehicle in the stand and holding the vehicle stably in place once up on the stand, as the stand has a good footprint.
  • the first trigger switch is positioned at the vertex of the wheel guidance portion.
  • the stand further comprises a wheel guide including an extendable/retractable bar fastened at the base portion of the frame (e.g., at the wheel guidance portion).
  • the wheel guide may include an extendable/retractable bar at each side of the wheel guidance portion.
  • the wheel guide comprises a low cohesion material between the bar and a contact surface of a tire.
  • This embodiment has the advantage of allowing for interaction between the bar and the tire with minimum resistance under transference in and out of the vehicle' s wheel.
  • the stand further comprises a second trigger switch (e.g., a fool pedal), so that, when the second trigger switch is tapped, the linear actuator activates, thereby lowering the free ends of the arm units and consequently the vehicle.
  • a second trigger switch e.g., a fool pedal
  • This embodiment has the advantage of providing a mechanism for triggering the activation of the stand for the lowering operation.
  • a remote control may be used instead of the first and second trigger switches.
  • the stand further comprises a stabilization pad including a panel attached in-between the free-ends of the U-shaped base portion.
  • the spool receivers are substantially Y-shaped.
  • substantially refers to the fact that the spool receiving portions may generally have a concave profile in place of a "v" profile. This embodiment has the advantage of enabling lifting of a vehicle having spools at its front/rear wheel assemblies.
  • the spool receivers are L-shaped (e.g., they may be attached to the arm units upside down). This embodiment has the advantage of enabling lifting of a vehicle having thin spools at its front/rear wheel assemblies.
  • the spool receivers are attachable to/detachable from the arm units.
  • This embodiment has the advantage that different types of spool receivers (e.g., Y- or L-shaped) may be attached to the arm units to match with the type of vehicle to be lifted.
  • the whole stand or one or more elements of the stands may be made of a material comprising metal such as aluminium, steel, etc., and combinations thereof.

  • FIGs.lA-B show: (i) two arm units 4, each arm unit 4 comprising an axle shaft receiver at one end for attachment and adjustability over an axle shaft 17 and an adapter connection point at the opposite end for the consolidation of multiple attachment apparatuses for various purposes (e.g., a spool receiver 5); (ii) a linear actuator 7 suitable for the type of recreational vehicle to be lifted (e.g., it may be rated at 400 kg for a motorcycle), wherein the linear actuator 7 may comprise a motor unit and a gear unit providing mechanical force for the raising and lowering of the arm units 4; (iii) first and second trigger switches 6, 8, e.g., electronic trigger switches, each comprising an open switch system utilized to activate a directional output to the linear actuator 7, wherein each electronic trigger switch in an open position is attached to an electronic relay, which, when closed, momentarily results in an electronic circuit activation and subsequent linear actuator 7 motion to achieve upward/downward motion of the lifting stand 100; (iv) a control box 1 comprising a control system for
  • a selector on the control box 1 may permit selecting, e.g., "automatic down", “manual up” or “off.
  • the control box 1 and the battery unit 9 may be integrated in a single unit.
  • the tire width gauge 12 is the means of adjusting the wheel guide 11 inward and outward for various tire sizes.
  • a push/pull shaft travels through a sleeve inside the gauge base 19 and pushes or pulls the wheel guide 11 at connection point 20 (ref. FIG.4A); consequently, the wheel guide 11 moves inwardly/outwardly thanks to pivot points 2 , 21" (ref. FIG.4A).
  • the push/pull shaft can be locked (e.g., by a bolt) into the position that coincides with the tire width indicated on the actual tire.
  • the first trigger switch 8 is used as the zero reference point for orientation - e.g., mis means that the wheel guide 11 is 50 mm or 90 mm from the center of the first trigger switch 8 for a tire width of 100 mm or 180 mm, respectively. This results in the most protruding point on a convex tire coming in contact with the first trigger switch 8.
  • each cover plate has two primary tension bolts, which exert down- ward pressure from the cover plate ends to the axle shaft 17. This downward pressure prevents free rotation of the axle shaft 17.
  • each arm unit 4 has two secondary (e.g., smaller) adjustment bolls, which are used to hold the arm unit 4 in position during adjustment or calibration of the arm units' position on the axle shaft 17.
  • FIGs.3A-B show: (i) a transport bar 16 (e.g., an attachable/detachable handle bar unit) for facilitating the movement of the stand 100 from one location to another (for example, the transport bar 16 may be stowed on the stand 100 when the latter is not in use and subsequently attached to the rear of the stand 100 to provide mobility of the stand 100 in combination with the transport wheels 13); and (ii) a tool holder 14 (e.g., a cylindrical unit with a closed base and an open top attached to the side of the stand 100) for the purpose of consolidating tools and other maintenance products.
  • a transport bar 16 e.g., an attachable/detachable handle bar unit
  • a tool holder 14 e.g., a cylindrical unit with a closed base and an open top attached to the side of the stand 100
  • FIGs.4A-B show a stabilization pad IS including a panel attached in-between the free- ends of the U-shaped base portion.
  • FIG.S shows an example of functioning of the stand 100.
  • a driver backs his motorcycle into the wheel guidance portion of the stand 100 with his motorcycle's rear wheel.
  • the control system is activated (e.g., a timing system such as a charge/relay system is activated for a certain time elapse, which would typically be the time needed for the arm units 4 to lift the motorcycle up to the desired height, e.g., the height where the arm units 4 are horizontal), thereby supplying power to the motor unit of the linear actuator 7.
