(21) FIG. 1 shows the lifter for the reparation of post-collision vehicles according to the invention comprising the four supports for lifting by the wheels and by the underbody/underchassis 6 removably applied to the upper platform/framework 2 of a lifter 1, wherein the lifting/lowering movement of the upper platform/framework 2 is obtained by means of a lifting mechanism 3, which comprises, at each of the two longitudinal sides of said upper platform/framework 2, a lifting mechanism 3 consisting of two pairs of levers articulated to each other, of which two parallel levers placed more externally, equipped at the upper end with casters sliding inside the upper platform/framework 2 and the lower end hinged with a pin to the base 4, while the two parallel levers placed internally are equipped with hinges at the upper end thereof, placed inside the upper structure of the upper platform/framework 2, while they are equipped at the lower end with sliding casters at ground level, along a trajectory concordant with the longitudinal axis of the base plane 4. The entire lifting mechanism is activated by a fluid-dynamic actuator 3.1, which has its lower end articulated on the pair of levers placed more externally, while the upper end acts on the pair of levers placed more internally by means of a device that favors the starting point at the beginning of the lifting step so as to obtain a minimum size when the lift is lowered.
(22) FIG. 2 shows the lifter for the reparation of post-collision vehicles in a completely lowered position with the supports for lifting by the wheels and by the underbody/underchassis 6; note the reduced overall height thanks to which the vehicles pass above the lifter, since the width of the lifter 1, complete with the upper platform/framework 2 is less than the minimum width of the inside of the wheels also of smaller cars, characteristics which make the positioning and lifting of the vehicle quick and easy. The supports for lifting by the wheels and by the underbody/underchassis 6 are also shown, of which two widened in a lifting position on wheels and two on the central opposite side equipped with elements for support by the underbody/underchassis 13 for the lifting by the underbody/underchassis with free wheels.
(23) In FIG. 3 the lifter for the reparation of post-collision vehicles is shown in a raised position with a vehicle on-board supported by the wheels by means of the supports for lifting by the wheels and by the underbody/underchassis 6, in which the minimum size of the supports for lifting by the wheels and by the underbody/underchassis 6 with respect to the lifter 1 can be seen, which allows the operator to comfortably intervene in the lower front and side parts of the vehicle body.
(24) FIG. 4 shows the support for lifting by the wheels and by the underbody/underchassis 6, in which the handle 6.2 can be seen, which is used to move the supports for lifting by the wheels and by the underbody/underchassis 6 along the upper platform/framework 2.

(30) FIG. 11 shows a further constructive form of the support for lifting by the wheels and by the underbody/underchassis 20, which appears to consist of a structure composed of a pair of projecting shelves 21, located at a certain distance from each other and fitted at each end with a handle 22, which is used for moving the support for lifting by the wheels and by the underbody/underchassis 20; in particular two constructive variants can be noted of elements for support by the underbody/underchassis, one of which is adjustable in height 16 and of a simpler shape 17, for the application to the support for lifting by the wheels and by the underbody/underchassis 20 in shelves. In this constructive variant the support of the vehicle is obtained by arranging the wheel of the vehicle itself between the pair of shelves 21.
(31) FIG. 12 shows a support for lifting by the wheels and by the underbody/underchassis with the sliding element 8 applied to the tubular profile 6.1 of the structure of the support for lifting by the wheels and by the underbody/underchassis 6, on which the blocking supports 10.3 are applied, which make it possible to firmly block both the sliding element 8 to the tubular profile 6.1 and the support for lifting by the wheels and by the underbody/underchassis 6 to the side profile 2.2 of the upper platform/framework 2.
(32) FIG. 13 shows the blocking system of the device which allows solidly blocking the sliding element 8 to the tubular profile 6.1, as indicated in FIG. 12, wherein the support for lifting by the wheels and by the underbody/underchassis 6, is blocked to the edges of the side profile 2.2 of the upper platform/framework 2 by means of the bracket 10.1, which is fixed to the body of the support 10.3 by means of a screw 10.2.
(33) FIG. 14 shows a device for adjusting 9 the support for lifting by the wheels and by the underbody/underchassis 6, realized by means of the shaped plate 6.3 which engages in the side profile 2.2 of the upper platform/framework 2; the blocking is guaranteed by the integral support of the inner end of the plate 6.3 of the support for lifting by the wheels and by the underbody/underchassis 6 on the profile 2.2 of the upper platform/framework 2; the setting system 9, consisting of the element 9.1, the bar 9.2 and the element 9.3, integral with the tubular profile 6.1, allows adjusting the inclination of the support for lifting by the wheels and by the underbody/underchassis 6, also visible in perspective in FIG. 16.
(34) FIG. 15 shows the blocking device 10 of the support for lifting by the wheels and by the underbody/underchassis 6 by means of the bracket 10.1, consisting of a shaped plate, which is solidly blocked to the side profile 2.2 of the upper platform/framework 2 by means of the screw 10.2.
(35) FIG. 16 shows the device for adjusting 9 the inclination of the support for lifting by the wheels and by the underbody/underchassis 6, which comprises one or more elements 9.3, welded to the lower part of the structure of the support for lifting by the wheels and by the underbody/underchassis 6 and with holes to allow the setting and blocking of one or more threaded bars 9.2, which are moved inside the holes and blocked by a pair of nuts 9.4; the setting is obtained by means of the threaded bars 9.2, which are screwed into or welded onto one or more elements 9.1, which rest on the inner lower part of the side profiles 2.2 of the upper platform/framework 2; the combined action on the two nuts 9.4 allows obtaining the correct and desired inclination of the support for lifting by the wheels and by the underbody/underchassis 6.
(36) In FIG. 17 two different types of pulling and anchoring equipment are shown which, if necessary, are used if the vehicle has to be fixed to the clamps and straightened with the use of a pulling arm: the first is pulling and anchoring equipment suitable for small repairs, consisting of a pushing/pulling arm 18, with relative fixing clamps, applied to the support for lifting by the wheels and by the underbody/underchassis 6 by means of the element 8; the second is pulling and anchoring equipment adapted to large repairs, consisting of a pushing/pulling arm 19, with relative fixing clamps 12, applied to the side profile 2.2, which is applied along the perimeter of the upper platform/framework 2, on whose side are applied the supports for lifting by the wheels and by the underbody/underchassis 6.
(37) FIG. 18 shows a lifter of the type with two independent lifting platforms (1)—with recessed cylinders or with scissor or parallelogram levers—of different shapes, with four supports for lifting by the wheels and by the underbody/underchassis 6 applied.
(38) From the description of the figures above it is possible to understand the advantages of the invention thanks to the possibility of using the same supports for lifting by the wheels and by the underbody/underchassis 6 which are applied in a removable/movable manner to the upper platform/framework 2 and are moved by the operator along the side profiles 2.2 of the upper platform/framework 2 to be used to lift the vehicle both by the wheels and by the underbody/underchassis with consequent free wheels of the vehicle.
(39) The possibility of performing these operations in lifting the vehicle by the underbody/underchassis and with free wheels is obtained using the elements for support by the underbody/underchassis of the low type 15, or high type 13 and 14, which are interposed between the underbody or underchassis of the vehicle and the support for lifting by the wheels and by the underbody/underchassis 6. The elements for support by the underbody/underchassis 13, 14, 15 which are in contact on the respective supports for lifting by the wheels and by the underbody/underchassis 6 by means of elements 13.3, 14.4, 15.3 fitted at the bottom with a slip-proof layer 13.5, 14.6, 15.5, preferably rubber and fitted with devices with threaded pins 131, 14.1 and 15.1, which support the vehicle being screwed into the respective intermediate bodies 13.2, 14.2, 15.2, adjustable in height and fitted at the top with slip-proof parts 13.4, 14.5, 15.4, preferably rubber; elements for support by the underbody/underchassis are also provided in a single block of slip-proof material, respectively suitable for being positioned on the respective supports for lifting by the wheels and by the underbody/underchassis 6 and on the shelves 21 of the support for lifting by the wheels and by the underbody/underchassis 20.
(40) The possibility of being able to use, in all working conditions, the supports for lifting by the wheels and by the underbody/underchassis 6 in combination with the pushing, pulling and fixing equipment, equipped with a pushing/pulling arm 18, with anchoring clamp, is obtained by blocking the element 8 to the side profile 2.2 of the upper platform/framework 2 by means of the bracket 10.1 which is fixed to the body of the support 10.3 by means of a screw 10.2; in this way the blocking of the sliding of the element 8 to the tubular profile 6.1 of the supports for lifting by the wheels and by the underbody/underchassis 6 is also obtained.
(41) In one constructive form the structure of the support for lifting by the wheels and by the underbody/underchassis 20 consists of a pair of projecting brackets 21, fitted at each end with a handle 22, which is used for moving the support for lifting by the wheels and by the underbody/underchassis 20. In this constructive form the support of the vehicle is obtained by means of elements for support by the underbody/underchassis 16, which are externally inserted into the shelves 21 of the supports for lifting by the wheels and by the underbody/underchassis 20, and are adjustable in height by means of a support with a threaded pin 16.1, which is screwed into the intermediate body 16.2 and which are fitted at the top with a slip-proof part 16.3, preferably rubber for the support of the vehicle. In this constructive form the vehicle is supported by the wheels, arranging each wheel of the vehicle between the shelves 21.
(42) The fixing of the support for lifting by the wheels and by the underbody/underchassis 20 to the upper platform/framework 2 is obtained by means of the bracket 10.1, fixed to the body of the support 10.3 by means of a screw 10.2; in this way it is possible to use in all working conditions the supports for lifting by the wheels and by the underbody/underchassis 20 to shelves, the pushing/pulling equipment 18 with fixing clamps, fixed on the element 8 when installed in the support for lifting by the wheels and by the underbody/underchassis 20.
(43) The peculiarity of the device for adjusting 9 the inclination of the support for lifting by the wheels and by the underbody/underchassis 6 consists in obtaining the adjustment by acting on the two nuts 9.4, which block the movement of the threaded bar 9.2 by applying a force on the element 9.1, resting on the lower part of the side profiles 2.2 of the upper platform/framework 9.1; in this way the parallelism or an inclination of the supports for lifting by the wheels and by the underbody/underchassis 6 with respect to the upper platform/framework 2 is obtained.
(44) To make the novelty of the invention more evident, FIG. 19 shows a diagram of how in the state of the art the support for lifting by the wheels and by the underbody/underchassis 6 is hooked to the upper platform/framework 2 of a known type, i.e. simply by means of a pin or plate 100 fixed to the element of the support for lifting by the wheels and by the underbody/underchassis 6 and which slides in a slot 101 formed in the structure of the aforementioned platform/framework 2. In a further constructive form, the support for lifting by the wheels and by the underbody/underchassis 6 is engaged on holes or seats present in the upper platform/framework 2 so that the operator must unhook and re-hook the support for lifting by the wheels and by the underbody/underchassis 6 for movement.
(45) Further constructional forms of the support for lifting by the wheels and by the underbody/underchassis 6 are also envisaged, of the hooking type of the support for lifting by the wheels and by the underbody/underchassis 6 of the upper platform/framework and the elements for support by the underbody/underchassis, provided that everything falls within the inventive concept defined by the following claims.
