Definitions

  • the present invention is broadly concerned with an improved, tiltable vehicle support stand, and a corresponding method, which greatly facilitates work on and around four wheel vehicles. More particularly, it is concerned with such a support stand which is especially designed to be particularly stable during use thereof, and which can be used to set up a vehicle without the usual time-consuming procedures of conventional supports.
  • the conventional practice in this regard is to initially elevate the front, rear or one side of the vehicle using an end lift or service jack, followed by positioning of a pair of individual- stands under the elevated part of the vehicle adjacent the elevated wheels. This procedure is then repeated on the opposite end or side of the vehicle in order to completely elevate the latter off the shop floor.
  • Governmental regulations generally require positioning of stands under a vehicle as safety devices, even if the jack used to lift the vehicle is left in place. To be effective though, they must be properly located and adjusted to positions just below the overlying structure. But, because of the trouble in locating and positioning the stands, mechanics often ignore the safety aspects of the stands in favor of saving time and simply leave the vehicle on the jack or jacks without underlying stands.
  • the vehicle support stand of the present invention broadly includes a base adapted to rest on a floor and which presents a pair of laterally spaced apart, floor-engaging side margins. Structure defining a pair of laterally spaced apart vehicle-engaging support regions is secured atop the base with the regions above the floor. Further, the vehicle-engaging regions are spaced apart a distance greater than the lateral distance between the base side margins.
  • the base comprises a pair of elongated, separate, laterally spaced apart foot members formed of metallic tube stock, with an elongated, transversely extending beam being rigidly connected to the foot members.
  • the beam supports a pair of relatively shiftable upstanding bodies of inverted, generally U-shaped configuration.
  • a resilient friction pad is affixed to the upper face of each U-shaped body, whereas the depending legs thereof are apertured and slidably receive the beam.
  • the support stand is of relatively low profile, and is especially designed to develop a righting moment during vehicle setup operations, and to be exceptionally stable in use.
  • the distance between the side margins of the base, the distance between the spaced-apart vehicle-engaging support regions, and the height of the regions above the floor are correlated such that the center of gravity of a supported vehicle lies in a plane passing between the base side margins. Further, when the vehicle is elevated and thereby tilted sideways during setup operations with the tires on one side of the vehicle engaging a floor, and a pair of support stands are placed under the sideways tilted vehicle similarly tilted, the center of gravity of the vehicle again lies in a plane which passes between the base side margins. In this fashion a righting moment is developed which urges the stands and vehicle back toward their fully righted positions.
  • the stand 20 includes a floor-engaging base 22, structure broadly referred to by the numeral 24 which defines a pair of laterally spaced apart vehicle-engaging and supporting regions 26, 28, and means such as welding which secures the structure 24 to the base 22 with the regions 26, 28 being located above the floor.
  • the base 22 preferably includes a pair of laterally spaced apart tubular metallic feet 30, 32.
  • the feet 30, 32 present corresponding floor-engaging side margins 34, 36, which in turn define the lateral extremities of the base.
  • the structure 24 includes an elongated, transversely extending, metallic tubular beam member 38 of rectangular cross section which is connected to the feet 30, 32 through a short connection beam 40 and appropriate welds 42, 44.
  • a handle 46 is welded to the upper face of beam member 38 between the feet 30, 32 and projects rearwardly from the beam 38 as viewed in Fig. 1.
  • the vehicle-engaging regions 26, 28 are identical and each include an upstanding body 48 of inverted, generally U-shaped configuration.
  • Each body 48 includes a planar, uppermost bight portion 50 and spaced apart, depending, converging leg plates 52.
  • a resilient pad 54 is secured to the upper face of each bight 50, and is comprised of a relatively dense foam rubber element and an overlying neoprene rubber impregnated fiberglass sheet 56 (see Fig. 5).
  • the sheet 56 provides an anti-slip surface in order to facilitate placement and use of the stand 20 beneath a vehicle.
  • the arms 52 are apertured as at 58 and slidably receive the beam 38.
  • the apertures 58 are dimensioned relative to beam 38 so that the bodies 48 can be laterally shifted along- the length of the beam by grasping one leg 52 and pulling the entire body. However, if it is attempted to shift the body 48 by applying a pushing force against one of the legs 52, the legs frictionally bind against the beam 38 and prevent such movement.
  • each body 48 further includes a depending reinforcing member 60 which is welded to the underside of bight 50 and extends to a point closely adjacent the upper surface of beam 38.
  • the member 60 is preferably formed of rectangular tubular metallic stock identical to that used in forming the beams 38, 40 and feet 30, 32.
  • Figs. 6-9 illustrate the use of a pair of stands 20 for elevating a vehicle 62 off a floor 64.
  • the vehicle 62 is a small automobile having front and rear wheels 66, 68.
  • the first step in the method involves elevation and sideways tilting of vehicle 62 such that the tires on one side thereof engage floor 64 and the tires on the opposite side of the vehicle are elevated.
  • Such sideways tilting of vehicle 62 can most preferably be accomplished through use of an improved side lift jack 70 which is placed between the front and rear wheels 66, 68 as viewed in Figs. 6 and 9.
  • the jack 70 is fully described in pending application for U.S. Letters Patent entitled “Side Life Jack for Unibody Automobiles", Serial No. , Filed: This application is expressly incorporated by reference herein.
  • the next step of the method involves placing a pair of vehicle supports 20 beneath the tilted vehicle 62.
  • the supports 20 are individually slid beneath vehicle -62 from a point adjacent the elevated side of the vehicle, . whereupon the adjacent end of the beam 38 is elevated and the remote vehicle-engaging pad 54 is wedged into contact with the underside of the vehicle at a point closely adjacent the floor- engaged tires thereof. This has the effect of holding the stand in an elevated and tilted orientation (see Fig. 6) similar to that of the vehicle 62.
  • Fig. 7 includes a line 72 which represents the center of gravity of the vehicle 62.
  • center of gravity line 72 lies in a plane which passes between the side margins 34, 36 of the bases 22 of the supports 20.
  • Figs. 10 and 11 depict vehicle 62 in its fully elevated position.
  • the stands 20 are essentially symmetrically transversely located relative to the underside of the vehicle, i.e., the center of gravity depicted by line 72 is centrally located between the vehicle-engaging regions of the stands and lies in a plane which passes centrally between the margins 34, 36.
  • Fig. 11 illustrates a situation where one or both of the stands 20 are asymmetrically transversely located relative to the vehicle, i.e., the stand 20 of Fig. 11 is shifted rightwardly as compared with Fig. 10.
  • the center of gravity line 72 lies in a plane which passes between the margins 34, 36.
  • a high degree of stability is imparted to the elevated vehicle 62.
  • Fig. 12 illustrates a further use of a stand in accordance with the invention.
  • a single stand 20 is employed immediately aft of the front wheels 66.
  • the stand 20 is positioned by conventionally raising the front end of vehicle 62 and placing the stand beneath the vehicle in an appropriate location.
  • the stand 20 in accordance with the invention has been illustrated with two separate vehicle-engaging regions 26, 28, those skilled in the art will appreciate that, for example, a single elongated structure lying along the length of beam 38, could be employed. In this instance of course, the overall structure still presents a pair of spaced apart vehicle-engaging regions which are spaced apart a distance greater than the lateral distance between the base side margins 34, 36.
  • base 22 has been depicted as being formed of separate feet 30, 32, a single plate or monolithic base could be employed. Numerous other alterations and modifications can also be made in the stand structure hereof, without departing from the spirit and scope of the invention.
