Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet metal repair table for an automobile body, which enables repair of damage caused by small accidents as well as larger accidents.

[0002]

2. Description of the Prior Art Sheet metal repair of an automobile body to remove the strain caused by an accident is actually applying a tensile force to a properly selected portion of the body.

Presently available equipment for performing such small sheet metal repair operations requires bulkiness, many operations, and the use of numerous individual intervening elements such as stools, stanchions, and movable ramps. By the way, these intervening elements are bulky and heavy to move, thus requiring a large area for their placement and their operation requires time and energy. Moreover, these intervening elements have no function other than contributing to the placement and removal of the vehicle from the anchor frame.

As an example, placing a vehicle on a sheet metal repair table generally includes the following steps.

Place the sheet metal repair table on the ground and remove the restraining elements used to secure the body to the table so that the vehicle can move on the table.

If a lifting mechanism is incorporated into the sheet metal repair table, the height of the lifting mechanism and the table relative to the ground is the height at which the ramp is essential to transfer the vehicle on the table. Therefore, it is necessary to provide a step for positioning these lamps.

Pulling the car onto the table by rolling.

Lifting the vehicle by applying lifting stress to the platform, for example via the lifting mechanism.

Pull out the access lamp.

Placing the stanchions or stools between the ground and the wheels of the car, and in a variant between the ground and the base of the car body.

Lower the vehicle until the body contacts the stool or stanchion.

-Return the platform to ground level. The body is supported by the stool or strut.

For the purpose of fixing the body of the motor vehicle to the sheet metal repair table, various restraining elements such as cross members and clippers are mounted on the table. This restraint or fixation is actually done near the weld joint (or weld edge) under the body.

Lifting the sheet metal repair table with these restraining elements until these restraining elements come into proper contact with the vehicle body.

Pulling out the stanchions or stools that are no longer in contact with the car from under the car.

-The lifting mechanism is lowered so that it can accept a sheet metal repair arm for fixing, ie a mechanical mechanism for applying tensile stress to the distorted body in place.

Place the sheet metal repair arm on the table.

Lift the table with the sheet metal repair arm so that the sheet metal repair worker can work at the height of a person.

The reverse operation required to remove the vehicle after performing the repair work involves the reverse sequence of steps.

A sheet metal repair stand for an automobile body, further comprising a central frame fixed to a lifting device and located between the longitudinal members of the frame, the central frame including wheel bearing shoes located on an extension of these longitudinal members, A sheet metal repair table is proposed in which the central frame is freely raised relative to it on the anchor frame and also provided with temporary fixing means for optionally connecting the central frame to the anchor frame.

It should be understood that:

-Since there is a lifting device that ensures vertical lifting, the operator can work without having to bend over.

[0024] The anchor frames may or may not be fixed to the central frame, and thus the anchor frames may or may not be subjected to the action of the lifting device, which makes them necessary in the prior art. Lifts the body either by wheels, by means of wheels via restraint elements, or without the need to ensure mutual operation, without using four stools that need to be well synchronized Therefore, it is very safe to use.

Considering that a lifting mechanism and a central frame are used, and therefore the anchor frame can inadvertently be in the stock position, the sheet metal repair table of the present invention is conventional with intervening auxiliary devices such as stools. It is more compact than the solution in.

The sheet metal repair table according to the invention provides a safe work for the body when it is fixed to the anchor frame by the fixing device, and thus when the body is only supported by the wheel bearing shoes of the central frame. to enable.

The sheet metal repair table as a whole can be movable or fixed with respect to the ground, if desired. When this table is fixed, a pit can be provided below it so as to minimize the concentration of work at the table height in the lowered position. Regarding the movability of the entire sheet metal repair table, since the lifting device is movable, it is possible to obtain the movability with high safety in use very easily. This lifting device is usually fixed to the central frame,
Therefore, it occupies a central position with respect to the platform and is therefore capable of movement in a good balanced position.

According to a preferred embodiment of the invention, which may also be combined, the central frame comprises two hollow longitudinal members in which a bar connected to the wheel bearing shoe is in sliding engagement. At least two wheel bearing shoes are connected by a connecting crosspiece, the bar is movable so as to allow a sliding engagement of the bearing bars of the sheet metal repair device, and the bar and the longitudinal bar.

The objects, features and advantages of the present invention will become apparent from the following description, given by way of non-limiting example in connection with the accompanying drawings.

[0030]

1 shows a permanent element of a sheet metal repair table according to the invention.

This sheet metal repair table basically comprises a central frame 1, an anchor frame 2, a lifting device 3 and four wheel bearing shoes 4.

The central frame 1 is usually fixed to the lifting device 3 so as to form a kind of lifting platform which advantageously moves vertically with the lifting device 3.

As shown in FIG. 3, the central frame 1 mainly comprises two vertical members 1A and 1B which are parallel to the longitudinal axis of the body to be repaired, and two members which securely connect these vertical members to each other. The book includes horizontal members 1C and 1D.

The lifting device 3 has the function of lifting and lowering the central frame 1 with respect to the ground level. This may be of any suitable form. Thus, for example, a deformable parallelogram lifting platform can be used which ensures vertical movement during lifting or lowering operations. However, in view of the good positioning of the central frame 1 with respect to the anchor frame 2 (see below), it is preferred that this lifting device has an essentially vertical movement, as will be explained later. For this reason, in the example shown, the lifting device comprises two pairs of side-by-side lifting arms, the two arms of each pair being articulated to one another in the central part. Of course, in this configuration, the lower ends (or upper ends) of the arms must be accessible or inseparable, respectively.

According to the conventional arrangement itself, the central frame 1
Is one of the cross pieces, in this case two cross pieces 1E, 1E, which are connected to the cross piece 1C, in order to cooperate with the lifting arm
F, and two vertical guide rails 1G, 1H arranged near the cross member 1D, the upper ends of two of the lifting arms are fixed to the connecting hardware 1E, 1F, and the other two are lifted. The upper end of the arm has guide rails 1G, 1H
It is attached so that it can slide inside. A similar arrangement is also provided on the lower ends of these lifting arms, with a coupling hardware and guide rails (not shown) on the ground frame or directly on the ground.

The longitudinal members 1A, 1B of the central frame 1 are advantageously hollow so that they can slidingly receive the bar 4A connected to the wheel bearing shoe 4.

The basic module formed from such a bar 4A and one wheel bearing shoe is shown separately in FIG. The module advantageously comprises a handle 10 for easy operation. The central frame 1 actually has four modules of the type shown in FIG. 4, more precisely two modules which are the same as those of FIG.
Two modules are mounted that are symmetrical about the longitudinal plane of bar 4A.

A module of the type shown in FIG. 4 is fixed inside the vertical member of the frame 1 shown in FIG. 3, for example a bar 4A.
A stop pin (not shown) is used that passes through the horizontal hole 11 and a pair of holes 12 provided at one end of the longitudinal member of the frame 1. It is preferred that this longitudinal member or this bar is provided with a plurality of holes, which allows the position of the wheel support module (or its symmetry) of FIG. 4 to be changed inside the longitudinal member of the central frame 1.

The central frame 1 is provided so as to be movable in the vertical direction with respect to the anchor frame 2 when the anchor frame 2 remains in a low position, for example, when it is supported on the ground. .

This anchor frame 2 basically comprises two lateral longitudinal members 2A, 2B connected to each other by two lateral members 2C, 2D. Basically, on the vertical members 2A, 2B,
The conventional restraint tool, an example of which is shown in FIG. 5, is also fixed by suitable means not shown. Form each lateral longitudinal member with two tubes and place these tubes side by side with a gap between them, through which bolts or any other suitable fitting can be secured in place. It is advantageous if the elements can also be arranged.
Therefore, to give an example, the lateral vertical member 2A has a gap 2A.
3 tubes, in this case two tubes 2A of square cross section
1 and A2. These strands preferably include hollow transverse tubular sections, designated 2E, where there are three per strand, ie each strand has two end portions and one intermediate portion.

These hollow tubular sections are shown in FIGS. 6A and 6A.
It would be advantageous to be able to secure a sheet metal repair device of any suitable type, such as the device shown in B, to the anchor frame. In the example shown, the device is essentially articulated in a pedestal bar 20 consisting of two parts A, B and a part A adapted to cooperate with a stressing element, not shown, such as a chain. Arm 21 and stand bar 2
It is provided with a jack 22 having both ends articulated on the part A of 0 and the arm 21, an operating lever 23, and preferably also with a moving mechanism indicated by a general reference numeral 24. In a variant not shown, the sheet metal repair device adapted to engage in the seat 2E is not of the articulated arm type of FIG. 6, but of carrier type (with jacks acting directly on the chain), or It may be of the traction transfer tower type (where the chain pulley is mounted above the tubular tower).

The two parts A, B of the bar 20 are connected to each other by a link C which allows relative rotation between AB about a longitudinal axis L--L, which in this case is horizontal.

Pivoting on the assembly axis, part A and element 2
1, 22 rotate to the right or left with respect to the part B.

A rotation lock is provided to place the arm 21 in the alignment required to apply the required tensile stress.

In the example shown, the part E shown in FIG. 6B has a series of holes 25 arranged in an arc about the axis L--L. This component is fixed on the trench in part B.

The trenches in the facing part A include parts having vertical holes, through which the locking fingers D are placed.
Slides and the selection of the relative position between A and B is made by the selection of the holes 25 in the part E into which the finger D fits.

The finger D is attached to the lever 2 by the rod F.
3, the lever 23 can therefore lock or not lock the part A with respect to the part B, depending on its angular position about its articulation transverse axis.

The inclination adjustment of the portion A becomes more precise as the number of the holes 25 increases (11 holes in FIG. 6B).

The moving mechanism is preferably fixed to the portion B.

The sheet metal repair tool as shown in FIGS. 6A and 6B can be arranged by sliding the bar 20 into the hollow tubular section 2E of any one of the longitudinal members of the anchor frame 2. The temporary fixing of this tool in the selected hollow tube section is achieved by a locking pin, not shown, which cooperates with a suitable hole, as in the case of the movable fixing of the module 4 to the central frame of FIG. Advantageously,

The longitudinal members of the central frame have the same internal cross section as these hollow parts, so that after removal of the module 4 (bars 4A and 20 also have the same cross section), the longitudinal members also slide and lock. It is advantageous to be able to receive the bar 20 of the sheet metal repair tool for.

The anchor frame 2 is optionally connected to the central frame 1.

This coupling can be done by any suitable means. Especially by ratchet mechanism or screws or bolts.

In the example shown in FIGS. 2 and 3, the central frame 1 has ears 13 on its cross members 1C, 1D, and only those fixed to the cross member 1C are visible in the figures. The anchor frame 2 is a cross member, that is, above the cross member 2C or 2D,
Alternatively, it is preferable to have a plurality of vertically protruding pieces indicated by 14 on the additional cross member. In this example, at least the upper portions of these pieces 14 are threaded. Each of these pieces 14 is adapted to cooperate with the ears 13 of the central frame 1. By screwing a bolt (not shown) onto the threaded portion of the piece 14, an effective tight connection between the frame 1 and the frame 2 is possible after the piece has passed the ears 13 of the frame 1.

In fact, these pieces 14 also ensure the function of centering the central frame with respect to the anchor frame. In a variant not shown, the piece 14 ensures only this centering function, while the rigid connection of the two frames is provided elsewhere, for example by means of a transverse stop pin which simultaneously traverses the longitudinal members of the two frames. Be seen.

The rigid connection of the frames to one another can be carried out automatically, for example by means of a ratchet mechanism of any suitable type. It is therefore preferable to provide a safety device which ensures permanent locking of the assembled ratchet of the two frames, i.e. locking which is released only at the moment when the central frame descends again to the ground. Separate the two frames only when the user is free.

Thus, for example, FIGS. 7-9 show a locking block suitable for fixing under the crosspiece of the central frame, for example at the location indicated by the dotted line 30 in FIG. 3 (four corners). It is preferable that each has a locking block).

This block includes a horizontally movable lock bolt 31 having a projecting structure, and the lock bolt 31 is inserted into a storage portion 32 provided in a portion forming a receiving seat firmly connected to the anchor frame 2. I'm out.

This block comprises a latch body 33 in which a horizontal hole 34, here of circular cross section, is provided, in which the lock bolt can slide. In order to prevent the lock bolt from coming off, a retaining ring 35 is provided in the annular groove 36 at the outlet of this seat.

A retaining ring 35 is also provided at the other end of the hole 34 and is used to retain a washer 37, on which a spring 38 is supported, which spring is attached to the washer 37 and the lock. It is compressed against the trailing edge of the bolt and thus drives this lock bolt in the direction of the overhang locking structure.

A control tie beam 39 is provided at the rear of the lock bolt.
Is fixed, which applies tensile force to the lock bolt,
The lock bolt can be retracted. This tie beam can be connected to an operating pedal or operating handle (not shown).

A vertical opening 40 extending parallel to the axis of the hole is provided across the lock bolt. The lock bolt further comprises a transverse bearing surface 41.

Further provided in the block 33 is a lower hole 42 leading downwards and an upper hole 43, here closed by a lid 44, of a larger diameter. The horizontal transverse dimension of the lower hole 42 is substantially the same as that of the opening 40 (see FIG. 8), and the lower hole faces the opening.

Locking fingers arranged to slide vertically are arranged in the lower hole and the upper hole. The finger 45 includes a rod 46 that passes vertically through the opening 40 and the lower hole. The finger 45 further comprises a head 47 adapted to slide the upper hole into the hole 34, facing the transverse bearing surface 41. In the example shown, this transverse bearing surface 41 abuts the front of the opening and the lowering of the head into the hole 34 is made possible by the side surface 48 along the opening.

A spring 49 supported by the lid 44 exerts a downward vertical pressing force on the finger 45.

The length of the stem 46 is such that when the head approaches the bearing surface through the hole, the stem projects downward. This head has a bearing surface 41
Higher than the finger 45
Can be in any form held horizontally by each of the holes 42, 43.

In the configuration of FIG. 7, the lock bolt is in a locked state, and the frame 1 and the frame 2 are firmly connected to each other.

When a pulling force to the right is applied to the lock bolt by the control tie beam 39, the lock bolt remains supported in place, supported by the head 47 on the bearing surface 41. As long as the fingers are in the protruding configuration of Figure 7, the locking cannot be disengaged.

If the fingers 45 are pushed back up against the spring 49, for example by bringing the frame 1 into contact with the ground, the head 47 is free to retract the lock bolt in response to the pulling of the tie beam. As such, it no longer faces bearing surface 41.

The device of FIGS. 7 to 9 thus guarantees locking that can only be actually neutralized when frame 1 and thus also frame 2 are in the low state.

Note that in this example, the vertical members of the central frame 1 are along the interior of the vertical members of the anchor frame 2. Since the wheel bearing shoes 4 movably fixed to the longitudinal members of the inner frame 1 project laterally outwardly, it can be seen that these shoes are approximately on the extension of the longitudinal members of the anchor frame 2. In this way, these longitudinal members constitute a wheel rolling path that allows the vehicle to ascend and descend by rolling on the wheels.

The tubular portion 1A-1B or 2E of the frame
It is noted that the elements 4A, 20 constrained within are of square cross section. However, this cross section is preferably polygonal in order to easily prevent relative rotation between the parts to be rigidly joined by snapping.

Placement of the vehicle on the above-mentioned sheet metal repair stand can be carried out quickly by the following procedure.

-Locate a ramp ramp 25 that shifts between the level of the wheel bearing shoe and the level of the ground. Two ramps 25 are sufficient at one of the ends of the anchor frame. These ramps can be completely mobile, but as a variant they can also be fixed so that they rest on the wheel bearing shoe 4.

Four wheels on four wheel bearing shoes, such as the car on the ramp 25, then on the two first wheel bearing shoes, then on the two longitudinal members of the anchor frame. These wheels are positioned with respect to the central frame by moving them to the position where they are placed and guiding them on the sheet metal repair table, taking advantage of the possibility of alignment according to the wheelbase of the vehicle. In this way, the state of FIG. 7 is obtained.

To lift the vehicle by means of the central frame 1 and the wheel bearing shoes 4 fixed to it,
Move the lifting device 3.

Fixing to the anchor frame 2 on the ground are the restraining tools referenced 6, which are preferably provided in open form (there are generally four restraining tools). In this way, the state of FIG. 8 is obtained.

Lowering the central frame 1, thus lowering the body until a suitable part of the body of the motor vehicle is fitted into the restraining tool in the open configuration. Close these restraint tools so that the body locks onto the anchor frame 2.

Continue the lowering of the central frame until it is firmly attached to the anchor frame. The weight of the vehicle is then removed from the central frame. Piece 14 of FIG.
This connection is guaranteed by mounting a bolt on top (or, in a variant, by the block 30 of FIGS. 7-9).

After that, the new actuation of the lifting device has the effect of lifting the body by means of the anchor frame 2 which was then on the ground. Thus, after lifting the module 4, a sheet metal repair arm of the type of FIG. 6 can be fitted in the part 2E or in the longitudinal members 1A, 1B.

Thus, according to the invention, in order to perform the function of lifting by the wheel and the function of restraining by the welded end under the car body, according to the operation to be carried out, it can be rigidly connected or not connected, and from the respective dimensions. Two frames are used, combined with.

By working with two frames, the two frames, which exhibit a predictable resistance to forces during the true meaning of sheet metal repair operations, can also be dimensioned to be lighter.

The sheet metal repair table of the type described here is used for diagnosis,
For the functions of measurement, minor repair, major repair, and car body modification,
Used for body repair.

The sheet metal repair pedestal described herein can be formed from a lifting platform having an upper portion that can or cannot be secured to the anchor frame. From this, in an emergency, leave the anchor frame on the ground,
The central frame can also be used with the lifting device as a simple lifting platform.

14 to 20 show a sheet metal repair stand 100 as a second preferred example of the present invention. The overall structure is very similar to the structure of the first embodiment described above, and the components corresponding to the components of the first embodiment include:
The reference numbers of the components in FIGS. 1 to 13 are added with the numeral 100.

This sheet metal repair stand 100 includes a central frame 1
01, anchor frame 102, lifting device 103, and four wheel bearing shoes 104.

The anchor frame 102 has longitudinal members 102A, 102B, 102C, 102D (preferably formed of two tubes separated by a gap) and, in addition to the hollow transverse tubular section 102E. It is distinguished from the frame 2 of FIG. 2 in that there is a hollow hollow tubular section 102F. This tensioning tool mounting position increases.

In addition, it is the anchor frame 102 that supports the locking block 130 that cooperates with the piece 114 provided on the central frame 101.

In FIG. 16, the piece 114 is a vertical member 101A,
It is located almost at the corner of the rectangle formed by 101B, 101C, and 101D. In this figure, due to the partial cutout,
Only one of these pieces 114 is visible.

The lifting device 103 includes a lower base 103A,
Advantageously, it is a separate device that includes the upper platform 103B and the pivot arm 103C. This device is seen in that it has an upper frame (and thus can be targeted to any lifting platform that can be used independently of the central frame or the anchor frame), and the central frame 101 (to the pivot arm itself It is independent (instead of being fixed to the upper table). To that end, the central frame comprises two crosspieces 101E adapted to be fixed to two transverse edges of the upper platform 103B of the lifting device, for example by means of two sets of four bolts.

The wheel bearing shoe 104 is advantageously rearranged in pairs into two wheel support elements 160, one of which is shown in FIG.

This wheel support element 160 comprises a single bar 1
04A and two basic modules of the type shown in FIG. 4, each formed by a shoe (located to the right or left), and a connecting crosspiece 104B that tightly connects the two modules. To be done. As a result, it is more robust and much easier to adjust.

As in the first embodiment, the bar 104
A is adapted to slide in the hollow tubular section of the longitudinal member of the central frame, this sliding preferably by rolling means not shown, and thus the connecting cross member 10
The length of 4B is the same as the distance separating these hollow tubular sections.

These elements 160 are suitable for selectively stopping in one of a plurality of possible positions with respect to the central frame so that they can be fitted to the wheelbase of various automobiles.

To that end, the hollow tubular section of the longitudinal member of the central frame is provided with a plurality of orifices, while the bar 1
04A includes a retractable crosspiece 161 that is controlled via a rod, not shown, using an operator-accessible lever or handle 162, eg, entering the capture handle 110, which includes: It ensures a reliable protection of these levers or handles 162, in particular against accidental impacts.

19 and 20 show the frame 10 of FIG.
2 locking block 130 and frame 10 of FIG.
A combination with one piece 114 is shown.

The horizontal thin plate 131 forming the horizontally movable lock bolt has a protruding shape, and the horizontal thin plate is inserted into a seat or slit 132 provided in the piece 114, as shown in FIGS. Very close to that shown in 9.

The block 130 includes a latch body 133 in which a vertical hole 1 adapted to receive the piece 114.
34 is provided and also includes a horizontal seat 135 in which the horizontal lamella 131 can slide.

This lamella 131 is pushed towards the hole by the lateral spring 136, while it is pressed (against the spring).
A pneumatic jack 137, for example, is provided for alternating movement from front to back. To that end, the lamella is connected to the jack piston 138 by a lateral rod 139 passing through the spring.

Also provided in the block 133 is a lower vertical orifice 142 adapted to receive the locking finger 145 and an upper seat 143 having a larger cross section, the locking finger 145 communicating with the head 147. Including a guide rod that slides inside,
The head 147 comes after the thin plate 131 with the fingers 145 being low when the thin plate 131 projects. Thus, there is an assembled lock as in FIGS. 7-9. This finger is held low by a spring 148.

In this lower state, the locking finger comprises a downwardly projecting part, here an elastic bearing 149. When the frame 102 is in the lower position, this bearing is relaxed by its elastic nature and strikes an unillustrated bearing surface at ground level (as in FIGS. 7-9), which causes the head 147 to laminae. The fingers are forced to rise to an elevated position above which the lamellas can retract. Thus, the separation between the block 130 and the piece 114 is possible only with the frame at ground level.

Such cooperation 130 + 114 is particularly reliable, and the use of the jack brings great convenience in use.

Of course, the above description has been proposed as non-limiting illustrations, and a person skilled in the art can propose many variants without departing from the scope of the invention.
