Definitions

  • the subject of the present invention is a lifting device for du scissor jack almost type vehicle. We use many jacks of this type in the industry.
  • These jacks have a foot, for support on the ground, on which is fixed an amount, an arm articulated on it, this arm being actuated by means of a control screw at the end from which is mounted a crank.
  • the jack's connection to the bottom of the vehicle body is provided by a jack head mounted on the articulated arm; this head must be able to pivot when lifting the vehicle so that the rocker panel remains vertical and in the same plane as the foot of the jack in the raised position.
  • Patent EP-A-327484 (BATZ S. COOP.) Describes in particular a such a lifting jack comprising a jack head made of material plastic mounted at the end of an arm by snapping in circular recesses provided on each wing of the arm, annular grooves being provided on each side of the head jack to adjust with the thickness of the arm wings. Said grooves do not extend over the entire periphery of the head jack to limit its rotation. This assembly cannot prevent jack head coming out of its housing after a short time of use.
  • the subject of the present invention is a vehicle jack with an independent head on the arm but does not requiring, to pivot, that a simple support on the vehicle.
  • FIG. 1 and 2 showing a jack in section according to the invention we see that it consists of a foot 1, of known configuration, on which is fixed a post 2, formed a ⁇ U ⁇ profile on which hinges on 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 further.
  • This arm 4 shown in Figure 3, in section, is also consisting of a en U ⁇ profile; at one of its ends 4a, it has an orifice 15 for fixing it to the upright 2 at by means of an axis 3; its other end 4b has on each of the wings of the profile a circular cut 16 open in 17; the cutouts 16 are intended to serve as a bearing and allow free rotation of the jack head 5.
  • the opening 17 is inclined by about 45 ° with respect to the longitudinal axis of the arm 4 and allows the introduction of the jack head 5 in the cutouts 16, which engage in the grooves 13 of the head of jack.
  • the width of the opening 17 is calculated so that cooperate with the diameter of the grooves 13 so that the head of jack is correctly positioned.
  • the arm 4 also comprises a lug 18 obtained by stamping, in the form of a ⁇ punctured ⁇ in the profile; this lug 18 is arranged under the axis of rotation of the jack head to form a stop at the rotation thereof.
  • the movement of the arm 4 is controlled so known 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 screw control is trapped in a spacer 8 arranged between the wings of the profile forming the arm 4.
  • a rolling balls 9 is fixed on the spacer 8 to facilitate rotation of the screw 6.
  • the spacer 8 pivots about an axis 10 mounted on the arm 4.
  • the jack head 5 is formed of a body substantially cylindrical 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 a annular groove 13 intended to cooperate with the cutouts 16 of the arm 4. These cutouts 16 will be housed in the two grooves jack head annulars 13 to form two bearings allowing its rotation.
  • the cylindrical body 12 has in its part central ( Figure 5 and 7) opposite the groove 12 b a flat 12 c with a recess 12d achieving a stop.
  • the central part of the body 12 is shaped so as to produce an elastic blade 12e.
  • the purpose of this particular configuration is to allow the introduction, in a good way, of the jack head 5, in its housing 16 provided at the end of the arm 4, by snap-fastening; to do this, we present the head 5 slightly inclined so that it engages in opening 17 and that 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. Head 5 being correctly mounted in the cutouts 16, it is rotated, the elastic blade 12e relaxes, the lug is finding between the stop 12d and said blade 12e locking all.
  • the jack according to the invention makes it possible to have a jack head independent on arm 4 while maintaining a simple support on the vehicle, the head swivels naturally between the stops 12d and 12e.
