Definitions

  • This invention concerns vehicle jacks of the type having two support members pivoted together, with a foot on one support member and a load engaging socket on the other, and a device to pivot the support members in rela­tion to each other so that the foot and the load engaging socket move towards or away from each other, whereby a vehicle can be raised or lowered.
  • the jack of this patent is of the type which inclu­de two support members pivoted together, with a foot on one support member and a vehicle engaging socket on the other support member, and a device for pivoting the su­pport members so that the foot and the vehicle engaging socket move towards or away from each other.
  • British patent 2053848 -METALLIFACTURE- shows a "Y" type vehicle jack with a fixed foot or base on its first arm, a second arm which pivots on the first and its threaded spindle which connects both arms through a nut arranged in the first arm and a bushing in the second.
  • the Threaded bushing is held in the bushing by means of a rear header and a front stop.
  • figure 1 describes a threaded spindle with a single thread direction along all its length.
  • figure 2 shows a variant with a protruding end of the second arm.
  • the threaded spindle is drawn with a single turning direction and the bushing in the second arm has been replaced by a nut similar to the one placed at the upper end of the first arm, while at the same time altering the housing plate for vehicle lead.
  • a "Y” jack is also known from British Patent 2134075 GERDES, with a first arm connected to a base plate, a se­cond arm that pivots on the first and a threaded spindle.
  • the base plate has two lugs projecting upwards at a right angle, which have holes in them, as have the wings of the "U" profile of the first arm, so as to position a kind of pin between them.
  • the lower end of the first arm has two bevels which rest, in the two jack positions, on the foot surfaces, defi­ning at least one position of the foot in relation to the arm.
  • the arm (5) is engaged in the position shown to points in a mechanism composed of parts (27)-(20)-­(22)-(25) ... etc., and the engaging is carried out by in­serting the projections of the shaft (23) in the hole (24) of the said mechanism.
  • Patent EP 0 232 836 STORZ shows a jack with a foot (18) assembled by means of a series of rivets (22) onto the arm (12), obviously without free rotation between both as the help of a spring (30) is needed.
  • the stop between the arm (12) and the foot (18) is carried out through the lower edge of the arm (12) and on the floor plate (18)-(20).
  • the jack inclu­des two basic members, which turn around a point, and these two members are of a "U" cross section, for instance.
  • the bushing in question is also connected to another similar bushing arranged in the other member, which the spindle passes through and juts out at the opposite end.
  • the two ends of the spindle, connected with both bushings, are threaded and have threads cut in opposite di­rections, so that when the spindle is turned by the action of the crank handle, both bushing move.
  • the opposite end of the spindle to the crank handle can have a stop fitted to its free end in order to prevent the bushing on this side, when turning in one direction, from becoming unscrewed from the spindle.
  • the lower end or leg of the other support member is mounted on a foot which turns freely and is made up of a channel-shaped body with a stop built into it.
  • the foot and the leg turn freely and mutua­lly until an upwardly projecting edge of the stop touches the leg. With this, the exact position of the jack beneath the vehicle is assured.
  • the stop in question can be conve­niently formed with a projecting portion of the "U" shaped channel section that makes up the foot.
  • the foot is also equipped with a hook or coupling formed by a projecting portion of the said foot, which, when the jack is in its folded position, is prepared to couple with the part that makes contact with the bottom part of the vehicle, thus preventing the jack parts from making noise or rattling.
  • the part that makes contact with the vehicle is lowered as much as possible and then the foot of the other member is turned, so that the hook is inserted into the part that makes contact with the vehicle.
  • the jack crank handle is turned and consequently the spind­le, so that a tight fit is obtained between the hook and the part in question.
  • connection between the foot and the member of the jack on which the aside foot is fitted is one of free rotation, as has been made clear earlier.
  • this free turning can be achieved by providing the lower part of the support member with a series of holes made on oppo­site sides of its section, and positioning the foot on the end of said member, while at the same time making some facing projections on the sides of the foot which pass through the said holes, forming a rotating connection. If necessary, holes could be made in the foot at the points which have to be holed, to make the process easier.
  • the ends of this support member are provided with rounded su­pporter surfaces, which connect the foot and transfer the load.
  • the foot has a "U” section according to a medium vertical plane of its wings, and the bottom is also in an inverted “U” shape with its raised base and with the ends of the little wings of this bottom connected with the foot wings to produce spaces in which the rounded ends of the first support member or first arm are received.
  • the spaces mentioned are the ones that rest direc­tly on the ground and the raised base is that which has its longitudinal ends occupied by the stop towards one side and by the hook towards the other side.
  • the stop has a raised surface, which connects with one side of the first arm, precisely with the outer bottom of the "U” that makes up the first arm and at a certain distance from its lower end, which is rounded. This roun­ded end is what rests on the inner sides of the foot.
  • the hook for connection with the second arm is elimi­nated, and a gap is made in the middle area of the raised base of the said foot to house a pressure-fitted plastic or rubber part, which protrudes upwards and downwards from the base.
  • the portion that protrudes downwards is bulged and outwardly convex so that it makes contact with the ground and acts as a non-slip devide for the foot itself.
  • the upwardly protruding portion has a central recess and two raised sides, to receive the support part for the vehicle bodywork, as will be explained more fully later.
  • the raised area of the foot that houses the plastic or rubber part is also equipped with the stop for the leg.
  • there is no opposing hook on the other end as it has been eliminated and its func­tion is performed by the folding and support part of the patent.
  • the foot assem­bly is turned until the upper face of the folding and support part takes in the vehicle support part.
  • the support member that includes the foot is lowered, to then turn the said foot so that the folding and support part takes in the support part of the other support member.
  • the jack crank handle is turned in order to achieve the appropriate tightness between the said folding and support part and the vehicle bodywork support.
  • the contact is very secure and also totally free from causing any kind of noise.
  • a support base assembly (7) turns on point (8) in re­lation to member (8).
  • a jack is shown, of the type des strictlycribed in previous paragraphs, which incorporated the fea­tures of the patent.
  • These features can be used individua­lly or as a whole together with some or all of the other features of the jack shown in figure 1, for instance, and together with some other features of other types of "Y" jacks, such as those shown in Spanish Patent Application No 8800105.
  • this version of the jack includes two members, a leg (12) and an arm (13) which turn around a point (14). Both the arm (13) and the leg (12) are made of channel-shaped section.
  • the two ends (16) and (17) of the spindle (15) are provided with threads in opposite directions, in such a way that when the spindle is turned, both bushing (18) and (20) move.
  • the end (21) of the right portion of the spindle, which protrudes out from the bushing (20) can be equipped at its free end (not shown), with a stop to pre­vent its becoming accidentally unscrewed from the bushing (15).
  • a part (22) At the end of the member or arm (13) further away from the other member or leg (12), there is a part (22), preferably made of hard plastic material, which makes contact with the bottom side of the vehicle when the jack is used.
  • the hollow (23) in the part (22) receives the sill seam weld or projection of the vehicle.
  • the lower end of the leg (12) is mounted on a foot (25) which turns freely and is formed by a "U"-shaped profile or channel.
  • This foot (25) has a stop (28) incor­porated into it.
  • the foot (25) and the leg (12) are turned until the upper end of the stop edge (28) touches the leg (12) at (30), as shown in the figure. With this, correct positioning of the jack beneath the car is assured.
  • the stop (28) the stop can be conveniently formed by a projecting portion of the channel section that makes up the foot (25).
  • the foot (25) is also equipped with a hook (29), also formed by the projecting portion of the foot (25), which, when the jack is in its closed or folded position, can engage the part (22) by inserting itself into the groove or hollow (23) of this part, this preventing the jack parts from rattling or making noise.
  • the arm (12) is lowered as far as possible and then the foot (25) is turned to the posi­tion shown, so that the hook (29) takes in the part (22) and then the crank handle of the jack is turned in the direction used when raising the arm, until the said hook (29) is tightly pressed against the part (22).
  • connection (32) between the foot (25) and the leg (12) is free turning and is shown in figure 4, which corresponds to the cross-section view II of the jack foot carried out in figure 2.
  • This connection between foot (25) and leg (12) can be carried out by providing the leg (12) with holes on opposite sides of its "U" channel section, for example holes (31) and positioning the foot on the end of the leg, while at the same time the sides of the foot (25) are holed to form projections (32) so that these metallic projections pass through the holes (31) to form the giratory connection.
  • the ends of the leg (12), at this side, have rounded support surfaces (26) which engage on the foot (25) and transfer the weight.
  • Figure 5 shows the variant of the part or foot (25) of one of the jack support members, which turns freely on the position (24) when it is mounted onto the said member.
  • the section made for this view is that of a middle vertical plane according to the axis (24), and the central or bridge area (27) can be seen, in which is included, for example by pressure, the folding and support part (35) of the patent.
  • This part (35) protrudes downwards through its downwards projection (36) to ptoduce a support surface for the foot (25), which is of the non-slip variety because the part is made of rubber, plastic, etc.
  • the bridge area (27) is provided only with the stop (28) for its contact with the support member or leg, and the opposite end is straight.
  • the part (35) protrudes upwards with a central sec­tion (39) and two raised sides (38) and (40) as illustra­ted in figure 5.
  • the jack is shown, in the fol­ded position, with the two support members (12) and (13), of which member (12) incorporates the foot (25) of the patent and member (13) has the vehicle support part (15).
  • the spindle (17)-(15)-(16) is connected to the threaded sections (33) and (34) and the tilting or pivo­ting point (14) of the two members (12) and (13) can also be seen.
  • the support for the edge (37) is wide, so that su­fficient pressure is brought to bear to prevent any possi­bility of noise, once that the jack crank handle has been turned.
