This vertically movable support means comprises a pair of vertical tubular means 4 which are placed at a suitable distance apart within the tubular vertical beam 1a of the frame means 1 and are movable perpendicularly thereto. ing. These pairs of vertical beams 4 are each fixed to the lower ends of a pair of upwardly inclined beams 5 extending to the upper left as shown in FIGS. 2 and 3. Therefore, these beams 5 are
Each will be integrally fixed at its lower end to the pair of tubular beams 4. In the left wall of the tubular beams 1a of the frame means 1, each receiving a tubular beam 4, a vertical slot is formed in each case, in which the lower ends of the inclined beams 5 can move freely. There is. By means of a pivot pin 6, the upper end of the tubular beam 4 of the vertically movable means is pivotally connected to an elongated beam 7 extending rearwardly from the beam 4 and across the inclined beam 5. In other words, by pivot 6,
The beams 7 of the pair of vertically movable means can be tilted with respect to their vertical beam 4, and these beams 7 also form part of the ramp means which can be tilted, as will be clear from the following description. It means that it is forming.

This vertical displacement means includes a hydraulic unit 8 consisting of a suitable piston and cylinder, the cylinder being connected to a suitable source of hydraulic fluid pressurized in a suitable manner, although not shown in the figures. ing. The lower end of the hydraulic unit 8 is pivotally connected to a rigid bracing structure fixed to and forming part of the frame means 1.
The upper end of the hydraulic unit 8 is connected to a framework extending between the paired beams 7 and fixed thereto. Therefore, when pressurized hydraulic fluid is supplied to the unit 8 and the hydraulic unit is extended, the paired beams 7 are formed by the pivots 6 as shown in FIGS. 2 and 3. When the unit 8 retracts, the beam 7 turns counterclockwise around the pivot 6 and descends.

The beam 7 of the vertical support means comprises beams 11 and 12 projecting horizontally laterally from the beam 7 as best shown in FIG. In the example shown, the beam 11 is fixed directly to the beam 7 and at the same time projects laterally therefrom. However, the beam 12 is mounted on a sleeve 13' slidable along the beam 7 and passed through the opening of the selected beam 12 placed on the beam 7 as outlined in FIG. It can be fixed in a selected position along the beam 7 by a locking pin 13 received in the opening. The beams 11 and 12 each have a gripping means 14 for gripping a body part of the motor vehicle.
It is equipped with

The vertically movable support means include ramp means formed partly in the beam 7 as shown above and tiltable about the axis formed by the pivot 6 as already explained. I'm here. The ramp means further includes plate means over which the wheels of the vehicle can move as the vehicle moves over the ramp means. The plate means includes a pair of front plates 15 which pivot at their rear ends on horizontal rods 15a, and whose inner portions are connected to the beam 7.
The outer ends are fixed to a pair of plates fixed to the outer ends of the horizontal beam 11. plate 1
The front end area of 5 is placed in front of the frame means 1, resting on the structure described below. In other words, as schematically shown in FIGS. 1 and 2, the frame means 1 includes a beam assembly that partially projects laterally below the plates 15 and on which these plates rest. Fixedly supported.

The plate means comprises a plate 1 whose front end is supported by a wheel 17, as schematically shown in FIG.
It includes a pair of rear plates 16. These plates 16 are arranged in the rear end region as shown in FIGS. 1 and 2.
It is pivotally connected to a pair of rods 16a fixed to the beam 7 and extending laterally therefrom as shown. In the rear end region of the plate 16, blocks 18 and 1 are provided on the outer surface of the beam 7.
9 are fixed and these blocks are placed below the rear end area of the beam 7 and are placed at a suitable height to engage the rods 18 and 19 after being placed at a selected height with vertically movable support means. Support structure 1
9' can be engaged. FIG. 2 shows the block 19 in the raised position of the vertically movable support means.
A suitable support structure 19' for mating with is shown in phantom. In order to make it easier to drive the motor vehicle and place it on the ramp means or straightening table, a pair of rear plates 20 are provided, which are fixed to the rear end area of the beam 7. It can freely pivot on a horizontal rod 20a that projects laterally from there. The plate means also includes a pair of plates 21 extending between beams 11 and 12 in the manner shown most clearly in FIG. plate 16
The front end of the beam rests on a pair of rods which are fixed to a sleeve 13'' which can slide on the beam 7 and which fixedly supports the beam 12, and which extends laterally from the same. Of course, the cross sections of the beam 7 and the sleeve 13' are not circular but rectangular, for example, so that the sleeve 13' cannot be turned around the beam 7. It will be understood that the sleeve 13' can only be displaced longitudinally along the beam 7.
These sleeves 13' fixedly support the front transverse rods 21a, which support the rear end of the plate 21. The front end of plate 21 is placed immediately to the left of fixed beam 11 and rests on a rod 21b which is fixed to beam 7 and projects laterally therefrom as shown in FIG. These plates 21 can be easily removed from the rods supporting them. for that,
The plate 21 has generally U-shaped spring clips on its lower surface that easily snap into and out of the rods that temporarily support the plate 21. It may be possible to do so.

As clearly shown in FIG. 3, the hydraulic vertical displacement means (hydraulic unit) 8 are extended to return the beam 7 and therefore the entire structure supported by it to a horizontal position. The beam 7 can also be locked in this horizontal position by operating the locking means 9. Once the lock 9 has thus locked the beam 7 in the horizontal position, the lock 10 is moved into the unlocked position and the vertical displacement means 8 are further extended to move the entire vertically movable support means 4-7. It is then raised to a selected height relative to the frame means 1. At this height, the locking means 10 is returned to the locking position in which it locks the beam 4.

The several gripping means 14 are all made of the same construction. 4 and 5, one of the gripping means 14 is shown in detail;
In the particular gripping means of the figures and FIG. 5, one of the laterally extending beams 12 is shown. Fourth
Referring to the figures and FIG. 5, each gripping means 14
is the beam 12 moving in the longitudinal direction of the beam 12.
It can be seen to include a first gripping jaw 22 supported by. The jaw 22 has a pair of side plates between which the beam 12 extends and which are secured to transverse plates placed above and below the beam 12. The lower end region of the side plates of the jaw 22 is fixed to a sleeve, through which passes a pin 23 which extends laterally beyond the pair of side plates of the jaw 22 and which engages the cooperating gripping jaws 24. It serves to pivotally support a pair of side plates. These side plates of the jaw 24 are located at their upper ends;
They are secured to each other by laterally extending gripping members facing laterally extending gripping members of the jaws 24. The lower portion 30 of the elongated body or chassis portion 29 is gripped between these gripping members. Thus, as is well known, conventional motor vehicles are provided with lower elongated beams 29 on opposite sides thereof, with dependent portions 30, as schematically shown in FIG. These dependencies are conveniently adapted to be grasped as shown.

All parts of the gripping means are made of solid and fairly rigid metal parts. The side plates of the jaws 22 are interconnected by a laterally extending member below the gripping means extending between them, the laterally extending member being inclined with respect to the beam 12 and , rests on the upwardly inclined surface of the axially bored wedge 28 as shown in FIG. A pair of side plates of jaws 24 fixedly support a coaxial sleeve;
These sleeves receive the opposite ends of transverse pins 25 which, in their central regions, pass freely through the axial bores of wedges 28 and are threaded. It is fixed to a bolt 26 on which a nut 27 is attached. By loosening this nut, the entire gripping means can be displaced longitudinally along the beam 12. Tightening this nut 27 not only brings the jaws 22 and 24 into engagement with the body part 29, but also simultaneously acts on the wedge 28 to tighten the gripping means as shown most clearly in FIG. can be tightened to the beam 12. Thus, by simply manipulating this single nut 27, it is possible to simultaneously fix the position of the gripping means and place it in mesh with the body part 29.

Reference is now made to Figures 1, 2, 6, and 7, which illustrate portions of the structure of the present invention forming the telescoping beam means. The telescoping beam means includes longitudinal beam means extending longitudinally with respect to the vehicle gripped by the gripping means 14, while transverse beam means extending transversely with respect to the vehicle. . This means that the longitudinal beam means extend parallel to beam 7, while the transverse beam means extend parallel to beams 11 and 12.

In the example shown, the vertical telescoping beam means
It is fixedly supported by frame means 1. This vertical telescoping beam means consists of an elongated hollow tubular beam 3 of non-circular cross-section, such as a square cross-section.
Contains 1. This beam 31 is fixed to the frame means 1 at its left or rear end, as shown in FIG. Keep the height clear. Inside this hollow beam 31, an elongated beam 33 having the same cross-sectional shape as the beam 31 is slidably inserted.
3 is slidable longitudinally relative to the beam 31 and extends forward a selected distance from the beam 31.

The beam 33 of the vertical telescoping beam means supports at its forward end a vertically extending hollow tubular member 33a within which is slidably received an elongated vertically extending tube or block 33b; Also supported by member 33a, member 3
Slide bolt 33d that can be placed into one of the rows of vertical openings formed in 3b.
is fixed in an appropriate manner by In its upper end region, the member 33b is formed with an axial bore receiving an elongated pin 33c.
Above this member 33b is placed an elongated beam 34, which at its lower end has a pair of ears 3.
4a, and the upper end of member 33b is received between these ears. Pins or bolts 33c also extend through these ears 34a, thereby connecting the beam 34 to the front end of the beam 33 and extending approximately 90 degrees to one side or the other in the direction of the arrow shown in FIG. It is beginning to cause a wobbling movement. The front ear 34a shown in FIG. 7 is a semi-circular plate 35 formed along a peripheral edge with a series of openings shown in FIG.
It is held in a fixed manner. The front wall of the member 33a is
It carries locking means 35a in the form of a slide bolt which can be selectively placed into one of the openings in plate 35 to lock beam 34 at certain selected positions about the axis of pin 33c. It can be fixed in any corner position. This beam 34
is arranged to support positioning means of the type described below with reference to FIGS. 8-11;
This positioning means itself is also arranged to support a straightening head 52 of the kind described below, so that it can thus be placed in a selected position for the purposes described below. They are arranged so that structures such as metal car bodies can be precisely straightened. For clarity, the figure shows beam 3 with possible deflection.
The positioning and tightening means cooperating with 4 are not shown. However, from FIG.
is formed with a plurality of longitudinally distributed openings therethrough, so that the sleeve can be slid along the beam 34 to position the tightening means at a selected height. I'll understand.

The transverse telescoping beam means includes a sleeve 36 surrounding the beam 31 and having the same cross-sectional shape as the beam 31;
6 can be slid along the beam 31 in the vertical direction. As is clear from FIG. 7, the sleeve 36
has at its forward end a locking means 37 in the form of a slide bolt which can be selectively received in a numbered opening in the beam 31, shown in the upper right corner of the beam 31 in FIG. have. In this way, the sleeve or beam 36 of the lateral telescoping beam means can be placed at a selected location along the beam 31 fixed to the frame means 1.

The opposite side walls of the sleeve or beam 36 fixedly carry a pair of coaxial transverse beams 38 which are, for example, welded at their inner ends to the opposite side walls of the sleeve 36. ing. These beams 38 are elongated tubular beams 3
9 and slidably supports it, so that this tubular beam is connected to beam 3.
8 form a lateral telescoping beam means. Each of the beams 39 has a plurality of openings formed in its front wall, one of which allows a bolt 40 to be installed, and
This bolt 40 enters into an opening in the side wall of beam 38 which slidably supports beam 38. Of course, these beams 38 and 39 have abutting, non-circular cross-sections and represent hollow tubular members.
That is, the lock 40 causes the beam 39 to
It can be fixed at a selected location along the beam 38. It will be seen from FIG. 6 that beam 38 has a scale that cooperates with the inner end of beam 39 to indicate to the operator the position of beam 39 and its position along beam 38.

The upper wall of the beam 39 fixedly supports a suitable support 39' (FIG. 2), on which the plate 15 rests in its front end region.

Furthermore, the beam 39 carries on its front wall a vertically extending tubular member 41, which is only shown in FIG. 6 for the sake of clarity. These tubular members or housings 41 are for example welded to the front wall of the sleeve or beam 39. The elongated rods 42 are each vertically slidable within the housing 41, and the housing is slidable into one of the rows of vertical openings formed in each of the vertically extending rods 42. It carries a slide bolt type lock 43 that can be stored. That is, the rod 42 is thus
The placement at a selected height and the lateral position of the bars can, of course, be determined by determining the lateral position of the sleeve 39. These members 42 are part of the straightening means. The member 42 is configured in a manner that will be apparent from the following description.
placed at a suitable height for engagement with the parts of the vehicle or the like carried by the support means, and then acted on by the moving means described below to displace them in the desired direction. , can apply deforming forces to vehicle parts to help repair them.

A pair of vertical beams 44 are fixed to the bottom wall of beam 39 by welding or the like. These beams 44 extend rearwardly past the frame means 1 and terminate below the removable plate 21 as already explained. The beam 44 fixedly supports at its rear end a housing 44' (see FIG. 2), which housings are arranged to support a pair of locating means, and which locating means are adapted to carry a pair of locating means. , is adapted to carry a tightening means of the kind described below. However, this structure supported by housing 44 is not shown in the figures for clarity. However, with this structure,
This makes it possible to work on parts of the vehicle located behind the frame means. Pair of hollow beams 39
has a vertically extending housing 45 at its outer end.
are fixedly supported, and these housings are closed at their lower ends and are adapted to carry compressed springs at these ends inside the housing 45 acting on a vertical member 46 that is slidable within the housing 45. It's summery. These members 46 are thus subjected to a spring load. A pair of locks 47 in the form of suitable slide bolts can be selectively received in a series of vertical openings formed in each of the vertical members 46, thereby parts,
Can be fixed at a selected height. These members 45 and 46 form part of a positioning means carried by lateral telescoping beam means, each of which is of course guided by a tubular housing 45. horizontal guide members 48 positioned above each vertical member 46. This horizontal tubular guide member 48
are rotatably mounted to the upper end of the vertical member 46 so that they can each rotate about their vertical axes. These guides 48 can rotate through an angle of about 180 degrees. Locking means 49 are provided for locking these tubular guides 48 in each selected angular position. In this case, the locking means 49 is
selectively into one of a row of circular openings formed in a vertically slidable and horizontal plate fixed to the bottom wall of the tubular guide 48; It has the shape of a bolt that can be used. The center of this plate is located vertically below the axis of each tubular guide 48. These plates, optionally formed with a row of openings each selectively receiving a slide bolt of lock 49, extend themselves into an axial bore formed in the upper end of vertical member 46. Fixedly supported by vertical pins. The lower end regions of these pins placed in the bores are formed on the outside thereof with circumferential grooves for receiving the inner ends of the pins;
A pin extends through the wall portion of member 46 into the peripheral groove, thereby allowing member 48 to rotate but not move axially relative to member 46.

Elongate horizontal members 50 each extend into and through guide 48, with guides 48 and elongate members 50 abutting each other and having non-circular cross-sections, such as square cross-sections. The guide 48 carries slide bolt type locks 51 which are selectively received in one of a series of horizontal openings formed in the member 50.
The element 50 can thereby be positioned horizontally with respect to the guide 48.

This locating means is supported by the outer end of each member 39 and is also supported by the aforementioned component 45-5.
1, it includes a square cross-section sleeve 56 which can slide along the horizontal member 50 and has the same cross-section as this member. This cross section is the 8th
It is square as shown in the figure. These sleeves 56 are secured in selected positions along the horizontal members 50 by locking bolts 57 which are receivable in one of a series of openings formed in the upper wall of each member 50. can do. sleeve 56
each support a unit 52 forming a mechanically or hydraulically operated straightening head. Details of these straightening heads 52 are shown in Figures 8-11. Thus, the releasable locking means 57 allows the straightening head 52 to be placed in a selected position along the horizontal member 50 of the positioning means.

A pair of lateral beam displacement means (hydraulic units) 54 are provided to vary the length of the lateral telescoping beam means 38, 39, as best shown in the lower center portion of FIG. ing. These lateral displacement means 54 take the form of suitable hydraulic units, but these are preferably double acting and, as shown in FIG. In response to the applied hydraulic fluid, member 39 is moved to the right or left relative to member 33a fixed to the forward end of beam 33 of the vertical telescoping beam means. Thus, as shown in FIG. 6, the hydraulic units 54 are each mounted between the lower end of the member 33a and the inner end of the displaceable tubular beam 39. These units 54 make it possible to apply laterally horizontal pushing or pulling forces and to produce the necessary straightening or metal deforming forces acting in the horizontal lateral direction. Referring to FIG. 7, another double-acting hydraulic unit 55 is connected between the lower rear part of the member 33a and the ear part fixed to the lower front area of the sleeve 36 and extending downward from there. I understand that. This hydraulic unit 5
5 can expand or contract in response to hydraulic fluid to change the length of the longitudinal beam means. Of course, at this point the lock 32 is in the unlocked position and the beam 33 can now be displaced relative to the beam 31 by the action of the hydraulic unit 55. That is, this unit forms a vertical displacement means that provides a horizontal pushing or pulling force extending in the longitudinal direction to provide a straightening or metal deforming force. As shown in various parts of the drawings, graduated scales are placed at various locations to indicate the adjusted positions of the various components. By these,
Metal deformation work can be performed accurately.

Referring now to FIGS. 8 and 9, sleeve 56 supports a relatively short cylindrical member 58 for rotational movement, which member 50 therefore rotates about the horizontal axis of member 50. It turns out that you can do it. The rotatable member 58 is fixed with a rigid post or bar 59 tilted upwardly and to the right from the rotatable member 58 as shown in FIG.
This column or rod 59 is fixed at its upper end to the upper end of a cylinder 61 forming the hydraulic unit. Cylinder 61 is a double-acting cylinder and is the eighth cylinder.
Pressurized hydraulic fluid can be received through the flexible tube 61' shown in the figure. As can be clearly seen from FIG. 9, the rotary member 58
is located between a pair of circular flanges that are secured to sleeve 56. These flanges include a forward flange 62 formed with a series of openings around its periphery. Cylinder 61 is surrounded by an elongate tubular member 64 which is movable longitudinally along cylinder 61 and thus extends transversely to rotatable member 58 . This tubular member 64 carries on its left side, as can be seen in FIG. It is formed with an array of selectively centerable openings. In addition, the tube 64 has a guide rib 6 adjacent to its left side, as can be seen in FIG.
5 and this rib extends through a groove or slot formed in the rotatable member 58 so that the tube 64 is connected to the cylinder 6.
You will be guided to move along with 1. flange 66
carries a locking unit 60 which includes a locking pin 63 which is inserted into and out of the aligned openings of flanges 62 and 66. Can move. Therefore, this lock pin 63
is not in such an opening, the entire unit formed by the cylinder 61 and the slide tube 64 above it can rotate about the axis of the member 50. Furthermore, the tube 64 can be axially offset along the cylinder 61. When the rotatable member 58 is in the desired angular position and the tube 64 is in the selected position along the cylinder 61, the pin 63 is inserted into the flanges 62 and 6.
6 are placed through the aligned openings, allowing these parts to be maintained in the desired position. In this way, the structure can be moved to the horizontal member 5 as shown by the circular arrow in FIG.
It can be positioned angularly with respect to the zero axis. At the same time, of course, in this way
The axial position of the cylinder 61 can also be adjusted.

The tube 64 partially shown in FIG.
Immediately below the tube 6 is fixedly carried a pair of circular rings 64a defining a groove into which a series of rings 64a are secured to the tube 64 and which can also be clearly seen in FIG. A ring 64b formed with an opening is placed. ring 6
The portion of the tube 64 extending downwardly from 4a extends slidably into a rotatable cylindrical member 79 which can rotate about the axis of the cylinder 61. This rotatable member 79 fixedly carries an elongated member 78, as shown in FIG. The member 78 itself carries a locking means 67 in the form of a slide bolt in a fixed manner. The inner end of the locking pin is adapted to be selectively received within one of the openings in member 64b. This locking pin serves to support rotatable member 79 over tube 64 while selectively positioning tube 79 angularly relative to tube 64.

As shown in FIGS. 10 and 11, rotatable tubular member 79 has a pair of ears 68 and 69 secured thereto, for example, welded to member 79. As shown in FIGS. These ears 68 and 69 are formed with coaxial openings through which pins 70 extend, as shown in FIGS. and 69 extending horizontally. This pin 70 is located between the ears 68 and 69 in the jaws 71 and 74 of the clamping means.
It helps support the.

Jaw 74 includes a pair of side plates 75, one of which is clearly shown in FIG. That is, the side plate 7 of the jaw 74
5 comprises a sector-shaped part formed with openings distributed along its periphery. 10th
As shown in the figure, a horizontally extending tube 77 is fixed to the lower end of a member 78 fixed to a rotary member 79. This tube extends between plates 75. Opposite ends of tube 77 are connected to plate 7
5 and the plate 75 is free to rotate relative to it, so that the opening of the plate 75 can be aligned with the tube 77 (8th
(see Figure 10). The upper regions of ears 68 and 69 are formed with aligned openings coaxial with tube 77. Lock pin 77' is
The operator is arranged to pass through aligned openings in ears 68 and 69 and through selected openings in plate 75, thereby fixing the angular position of jaws 74. I'm starting to be able to do it. The jaws 74, of course, serve as clamping members and include a lower transverse portion fixed to and extending between the plates 75.

Jaw 71 has a lower clamping part adapted to cooperate with the clamping part of jaw 74. This jaw 71 extends between the plates 75 and is formed with a bore for receiving the pin 70. The jaw 71 has an angular shape, as shown in FIG. 8, and its upper region is formed with a slot for receiving a pin fixed to the piston rod 72 of the cylinder 61. It ends in an elongated section. This piston rod 72
is guided through a central opening made in a transverse plate fixed inside the guide tube 64. That is, in this configuration, when the lock pin 77' is removed, the operator can open the jaw 74.
It can be angularly positioned relative to pin 70 at a selected angular position. Locking pin 77' is then replaced to hold jaw 74 in the selected position. The cylinder 61 can then receive the hydraulic fluid acting on the piston rod 72, thus swinging the jaws 71.
4, it becomes possible to tighten it into an engaged state or remove it from an engaged state. The range of motion of these components is shown in FIG. 8 by solid and dotted lines.

If desired, member 78 may
and pin 77, which can be used to actuate them simultaneously, but such a structure is merely an option rather than a requirement.

Thus, the above structure allows the jaws 74 of the clamping means to be angularly positioned in a selected angular position with respect to the axis of the pin 70, while at the same time the jaws 71 cooperating therewith can be positioned on the jaws 74. However, it will be clear that it is possible to easily rotate it into and out of the clamped position. In addition to adjusting the jaws relative to their own axis of rotation in this manner, the clamping means are angularly positioned about the horizontal axis of the member 50 by the positioning means described above; It is also possible to position the member 46 angularly about its vertical axis. at the same time,
Element 46 allows the height of the clamping means to be adjusted, while element 50 also allows adjustment of the horizontal position of the clamping means. In this way, it is possible to place the clamping means of the straightening head 52 in any required position.

As indicated above, although the locating and tightening means of the present invention have been described only at the outer end of member 39, similar structures may be placed on beam 34 as well as at housing 44'. be able to.

In FIG. 2, the structure of the invention is shown in solid lines in the position it assumes when it is ready to receive a working vehicle. By means of the wheels 3, the entire structure of the invention can be moved to any desired position with great ease. When the structure is in the position shown in Figure 2, the worker drives the vehicle up to the ramp and
It is possible for the wheels of the vehicle to rest on the plates 15 and 16. When the front wheels of the vehicle are placed on the plate 15, the paired front gripping means 14 are positioned relative to the vehicle to grip the elongated side body or chassis portion 29 in a position adjacent to and behind the front wheels. become. Vehicle is plate 1
Supported in this way by 5 and 16,
Intermediate plate 21 is removed. at this point
By displacing the pair of locking means 13 to the unlocked position, the sleeve 13' is displaced longitudinally along the beam 7, and the beam 12 and the pair of gripping means 14 carried thereon are moved to the chassis or body part 2.
It is possible to place it at any position along 9.
Of course, even if the sleeve 13' is displaced forwardly from the plate 16, the plate is still supported by the wheels 17. At this time, some of the gripping means 14 are laterally offset so that they become aligned with the body part to be gripped.

At this point, the operator must check locks 9 and 1 in Figure 3.
0 is in the unlocked position. Once it has been established that these locks 9 and 10 are in the unlocked position, the operator introduces pressurized fluid into the cylinder of the hydraulic unit 8, causing the unit to expand and move vertically. The entire movable support means is raised relative to the frame means 1 and assumes a position as shown by the chain line in FIG.
Accordingly, the front plate 15 has portion 39'
At the same time, the object is tilted at a large angle from its original horizontal position. As a result, the front pair of gripping means 14 engage and support the vehicle, while the front end of the vehicle
The front wheel is now plate 15 as it continues to be lifted up.
They will no longer mesh with each other. When the front wheel no longer engages with the plate 15 in this way,
Lock 10 is placed in the locked position and additional pressurized fluid is admitted to unit 8 to further expand the unit, thereby lifting the ramp portion of the vertically movable support means and causing it to expand further. until it assumes a horizontal position. During this operating part, the rear plate 16 remains supported by the wheels 17, so that the ramp part swings upwards relative to the plate 16. It should be noted that the plate 16 only pivots upwards at its rear, and this rear is pivotally connected to the beam 7 in the manner already described. By this operation, the gripping means 14 of the rear pair engage the body of the vehicle at the vehicle section 29, so that when the beam 7 and the rest of the ramp section are placed in a horizontal position, the vehicle has several grips. Supported by the means 14, the wheels of the vehicle are no longer supported. Now tighten the several nuts 27 so that the vehicle is gripped tightly and remains stationary relative to the vertically movable support means. Of course, once the beam 7 reaches the horizontal position, the lock 9 is placed in the locked position so that the beam 7 maintains the horizontal position. At this point, the vehicle can be raised to any desired height.
The rear plate 20 swings down to ensure that the vehicle remains in a high position according to its height and, as pointed out above, is fitted with a suitable support 1.
9' may be placed in engagement with ears or struts 18 and 19 to maintain the vehicle at the desired height without the need for the entire weight of the structure to be carried by the fluid in unit 8. . However, whenever it is desired to move the vehicle vertically, the vehicle can be raised a small amount of height and then these supports removed, allowing the vehicle to be lowered or raised further as desired.

Once the above-mentioned parts of the structure of the invention are in this position, the metal deformation operation can proceed.
If, for example, a car is involved in a collision and the front outer skin plate, inner fender, and its frame box are inadvertently bent to the left and rear, the straightening or metal deforming operation would be Proceed along the lines below.

The lock 37 is placed in its unlocked position and the sleeve 36 is moved by the unit 55 to the beam 31.
, the transverse beam 39 is placed in such a position that the straightening means 42 are placed below the curved frame beam of the vehicle. The rods 42 forming the straightening means are laterally adjusted by means of lateral displacement means 54 to bring them into proper alignment with the damaged component of the vehicle. On the damaged side of the vehicle, the straightening member 42 is raised to the level of the frame beam, and when the appropriate unit 54 is actuated, the lifted member 42 acts on the frame beam and straightens the frame beam. Press it to remove the curls.

As far as the above example is concerned, the top of the inner fender is also pushed in, so the straightening head 52 is operated to apply a straight pulling force to the top of the fender from the inside. This is done by lifting the straightening head 52 by rotating the horizontal member 50 about the axis of the member 46 while vertically adjusting the appropriate vertical member 46 and placing the clamping means in the desired position. It will be done. The appropriate hydraulic unit 54 is then operated to effect the necessary lateral movement while the tightening means clamp the damaged part of the vehicle, and by the force available from the unit 54 the damaged part is removed. To be able to carry out appropriate metal deformation work to repair the part. If a longitudinal force is required, unit 55 is used for this purpose. In this case, it may be necessary to remove the lock 32. It is also possible, if necessary, to apply an additional forward pulling force by the locating and tightening means carried by the beam 34.

When using the straightening head 52, place it at the required height and unlock the lock 57. Lock 63 also unlocks, thereby allowing cylinder 61 and tube 64 thereon to rotate freely in the direction indicated by arrow 53 in FIG. The tightening angle of jaws 71 and 74 is adjusted by pin 77', as already explained. The lock 67 secures the tightening means in the desired angular position relative to the axis of the cylinder 61. Of course, it should be noted that while the tube 79 is rotating, the entire clamping means also rotates with it, and the piston rod 72 rotates with the piston inside the cylinder of the unit 61. These various adjustment functions allow the clamping jaws to tighten the edge of the metal to be deformed or the edge of the plate, irrespective of the direction in which this edge or edge of the plate extends. Therefore, in the above example, the tightening jaws are set and the edge area of the inner fender is tightened by the force obtained from the unit 61.
Deformation operations can then be carried out by means of the telescoping beam system described above.

That is, the straightening head 52 can be used on any area that requires repair. With or without clamping jaws, the straightening head can be used to push door frame edges, windows, skirts, frames, inner and outer fenders, headlights, fixing frames, doors, etc. in any desired direction. It can be pulled or pulled. Since the straightening head itself has both straight and angled surfaces, these parts can be used to perform deformation operations. Also, by clamping various straightening tools in the form of rods of any desired shape into the clamping jaws, relatively narrow spaces can be accessed using these tools.

Once one side of the vehicle has been straightened, the straightening or metal deformation work is performed on the other side of the vehicle while holding this repaired side. Of course, the length of each deformation movement is
It can be read from various scales on the beam. If, after performing the deformation operation, it is determined that further deformation operations are required to achieve the desired shape, the deformation operation can of course continue.

In this way, by the vertical moving means 55,
A vertical push or pull force can be provided and, by means of a lateral displacement means, a lateral push or pull force can be provided.

One feature of the invention is that by unit 8:
It consists in applying a vertical push or pull force. This vertical displacement means 8 acting on the vertically movable support means can therefore also be used to supply vertical pushing or pulling forces. For this purpose, of course, it is necessary to remove the support block 19' so that the overall height of the vehicle can be changed. The clamping means remains clamped on the part applying a vertical push or pull force. Alternatively, the clamping means can clamp a suitably shaped tool so that it engages the part applying the vertical force. Next, the entire vehicle is vertically displaced relative to its clamped parts by means of vertical displacement means 8, applying the desired vertical pushing or pulling force. In the above description, the various details described and shown in the figures are only for the purpose of clarifying the concept of the invention. Various embodiments of the invention are possible within the scope of the following claims. Furthermore, the various hydraulic displacement means may be replaced by other types of power means. Furthermore, plates 15 and 16
All lowering plates can be made such that they can be lowered simultaneously at both ends, for example by means of suitable guide rails.
