2 Claims. (Cl. 25d10) The invention relates to a lifting frame for the assembly, repair and cleaning of motor cars.

The assembly, cleaning and repair of motor cars, particularly in garages and at the premises of other enterprises carrying on a service activity, was up to now usually performed above an assembled pit. Though the pit rendered the lower part of the car accessible, it made the performance of the work inconvenient and locally restricted. Similar drawbacks were also presented by hydraulic lifting gear.

The invention relates to a lifting frame by which, in order to facilitate the performance of the operations mentioned, the motor car is raised to a high level, so as to render the car easily accessible from below. According to a preferred embodiment of the invention, the frame itself is mounted on wheels, so as to enable the motor car raised to a high level on the frame to be conveyed in this condition from one part of the premises at which the work is being performed to the other as necessity may require. Further, this embodiment is also suitable for effecting the transport of disabled motor cars to the place of repair, as well for travelling workshops.

The annexed drawing represents such an embodiment of the invention.

Fig. 1 is a side elevation in the collapsed condition of the frame,

Fig. 2 is a ground plan of the same,

Fig. 3 is a section along line IIL-III of Fig. 1,

Fig. 4 is a side elevation in open condition of the frame,

Fig. 5 is a ground plan of the same, and finally, c

Fig. 6 is a section taken along line VIVI of Fig. 4.

The lifting gear to be described with reference to the drawing is built on the longitudinal girders a. The longitudinal girders a are carried by the running wheels I) connected to them in the usual manner. Roller guides c and joints i are fixed on the longitudinal girders a. Connected to the joints d, pivotable rods e are provided, which form rhomboids pivotable on both sides with the longitudinal girders a, and with the beams f by which the upper ends of the said rods are mutually connected, the said rhomboids being connected at their angle points by transverse rods g.

To the pivoting points of the rods e and of the beam a further rod 71. is connected pivotably. On the lower ends of the rods h is journalled the roller 2' rolling along the guide 0. Pairs of rollers z are mutually connected along the length of the longitudinal girder a, by the drawbars 7c, whilst pairs of mutually opposite rollers i are mutually connected by the transverse members m.

In the transverse girders n by which the longitudinal girders a are mutually connected there is journalled a screw 1" capable of being rotated by the motor 20 through the gear box 0. In one of the transverse members 112 a nut thread engaging with the screw r is provided, so that in consequence of the rotation of the screw 1, the rollers i, owing to the connection established by means of the draw-bars R, will move toward or away from the joints d, thereby causing the beams f to be raised, or lowered, respectively.

On the two sides of the lifting frame, tracks s are provided, on which the motor car to be worked upon runs up over the inclined plane it, which is removable at other times. By operating the motor 10 in the appropriate direction, the frame may be brought from its position shown on Figs. 1 to 3 into its position shown on Figs. 4 to 6, in which latter position the beams supporting the chassis of the motor car will raise the motor car to a high level. Raising the motor car in such a manner substantially facilitates the removal of its wheels.

Should it, for any reason, be desirable for the motor car to continue to be supported by its wheels in its raised condition also, the propping bar 11 is fitted into the suspension device u connected to the beams f, the said propping bar raising the beams w together with the gangways 8 supported on them, that is to say together with the motor car supported on the said gangways.

There is, of course, nothing to prevent the whole structure being made self-propelled on the wheels b. All that is necessary for this purpose is to equip the underframe constituted by the longitudinal girders a and the transverse girders n with a suitable vehicle motor and to drive the wheels I? by means of this motor. Use may be made for this purpose of the motor p.

What I claim is:

1. A lifting frame for the assembly, repair or servicing of automobiles comprising two longitudinal parallel laterally spaced girders, pairs of rods pivotally connected at one end to spaced points of each girder to swing above the same, a beam pivotally connected to the other ends of each pair of rods thereby to form a pair of deformable parallelograms, a transverse member connecting the two parallelograms for concurrent movement, pairs of props each pivotally connected at one end to each beam at the points of pivotal connection thereto of the respective pair of rods, a guideway on each girder, the other end of each prop having a sliding connection to said guideway comprising rollers journalled in said props, a longitudinal tie connecting the props of each pair and a transverse member connecting each prop of a pair to the corresponding prop of the other pair for concurrent movement of all the rollers on the guideways, a track on each side of the frame for receiving the wheels of the automobile to be lifted, means for suspending the tracks on the beams, a longitudinal draw member connected at one end to one of the transverse members con- LAszLo NAGY THURzo.
