Definitions

  • the present invention relates to a vehicle lifting device of the "scissor jack" type. Many such jacks are used in the industry.
  • These jacks include a foot, for support on the ground, on which is fixed an upright, an arm articulated on this, this arm being actuated by means of a control screw at the end of which is mounted a crank.
  • the jack is connected to the bottom of the vehicle body by a jack head mounted on the articulated arm; this head must be able to pivot when the vehicle is lifted so that the rocker panel remains vertical and in the same plane as the foot of the jack in the raised position.
  • the present invention relates to a vehicle jack comprising an independent head on the arm but requiring, to pivot, a simple support on the vehicle.
  • the jack according to the present invention is characterized in that it comprises a jack head having substantially the shape of a cylinder comprising, at each of its ends, an annular groove intended to allow its rotation in a bearing provided for this purpose on the arm articulated on the amount of the jack.
  • a groove intended to receive the underbody of the vehicle to be lifted extends radially over the entire length of the cylindrical body.
  • This jack head is also characterized in that it comprises in its central part an elastic tab or deformable lip intended to constitute a first angular travel stop; a second angular stop is disposed on this jack head to limit the pivot angle.
  • the jack according to the invention is further characterized in that the arm articulated on the upright formed by a "U" profile, made of sheet steel, which must receive the jack head at its free end, comprises two circular cutouts allowing the introduction of the jack head and its maintenance in these cutouts which cooperate with the annular grooves of said jack head so as to form circular bearings allowing its rotation.
  • the articulated arm also includes a lug intended to cooperate with the stops of the jack head in order to limit its rotation or pivoting as indicated above.
  • a jack according to the invention we see that it consists of a foot 1, of known configuration, on which is fixed a post 2, formed of a "U" profile "on which is articulated at two thirds of its height, on an axis 3 an arm 4 carrying at its free end a jack head 5 according to the invention which will be described in detail below.
  • This arm 4 shown in Figure 3, in section, also consists of a "U"profile; at one of its ends 4a, it has an orifice 15 for fixing it to the upright 2 by means of a pin 3; its other end 4b comprises on each of the wings of the profile a circular cutout 16 open at 17; the cutouts 16 are intended to serve as a bearing and allow the free rotation of the head of jack 5.
  • the opening 17 is inclined by about 45 ° relative to the longitudinal axis of the arm 4 and allows the introduction of the jack head 5 into the cutouts 16, which engage in the grooves 13 of the head jack.
  • the width of the opening 17 is calculated so as to cooperate with the diameter of the grooves 13 so that the jack head is correctly positioned.
  • the arm 4 further comprises a lug 18 obtained by stamping, in the form of a "punctured" in the profile; this lug 18 is disposed under the axis of rotation of the jack head to form a stop to the rotation of the latter.
  • the movement of the arm 4 is controlled in a known manner by means, in the example shown, of a crank 11 acting on a control screw 6 passing through a nut 7 articulated on the upright 2; the end 6a of the control screw is trapped in a spacer 8 disposed between the wings of the profile forming the arm 4.
  • a ball bearing 9 is fixed on the spacer 8 to facilitate rotation of the screw 6.
  • the spacer 8 pivots around an axis 10 mounted on the arm 4.
  • the jack head 5 is formed of a substantially cylindrical body 12 truncated at its upper part 12a and provided with a groove 12b over its entire length; this groove 12b is intended to receive the underbody of the vehicle to be lifted.
  • the body 12 has at each of its ends an annular groove 13 intended to cooperate with the cutouts 16 of the arm 4. These cutouts 16 will be housed in the two annular groups 13 of the jack head to form two bearings allowing its rotation.
  • the cylindrical body 12 has in its central part (FIGS. 5 and 7) opposite the groove 12b a flat 12c with a recess 12d providing a stop.
  • the central part of the body 12 is shaped so as to produce an elastic blade 12e.
  • This particular configuration is intended to allow the introduction, in the right direction, of the jack head 5, into its housing 16 provided at the end of the arm 4, by snap-fitting; to do this, the head 5 is slightly inclined so that it engages in the opening 17 and the cut edges 16 engage in the annular grooves 13; during this process the elastic blade 12e rests on the lug of the arm 4.
  • the head 5 being correctly mounted in the cutouts 16, it is pivoted, the elastic blade 12e relaxes, the lug being between the stop 12d and said blade 12e locking the assembly.
  • This mounting has the result of ensuring the limitation of the angular rotation of the head 5, and of making it impossible to dismantle it, the elastic blade 12e by abutting against the lug preventing the jack head from being in the angle of the opening 17 where the diameter of the grooves 13 allow its exit.
  • the jack according to the invention makes it possible to have an independent jack head on the arm 4 while retaining a simple support on the vehicle, the head pivoting naturally between the stops 12d and 12th.
