Definitions
- the present invention relates to an apparatus for the recovery of deformed metal elements and / or plastics, or even damaged, as a result of excessive mechanical stress such as, for example, a shock.
- the Applicant has proposed a method consisting in exerting on the deformed element a pressure generated by a cylinder, a balloon or the like, inflated by means of a fluid whose pressure is controlled.
- This method also involves two templates having the original shape of the deformed element that sandwich said deformed element. One of these templates is placed inside the deformed element while the other is placed outside of it.
- the invention therefore more particularly aims to solve this problem.
- an apparatus involving at least one support member equipped with temporary fixing means on the rigid structure of the vehicle and / or its body, a counter-support element on which can be fixed an actuator possibly equipped a template or the like and an adjustable mechanical connection in position and / or orientation between said support element and said counter-support element, said connecting element being designed to retransmit on the support element at least a fraction the force exerted by the actuator on the counter-support element.
- the aforesaid actuator may be of pneumatic type and comprise a pneumatic cylinder, an inflatable balloon or bellows or the like.
- the invention applies in a particularly advantageous manner to the recovery of deformations of the roof (roof) of an automobile, in particular, but not exclusively, deformations due to hail: It is known that during certain storms, it is forms hailstones of relatively large dimensions whose impacts on a body cause a multiplicity of deformations in the form of bowls. The recovery of a body that has suffered such damage is very long and expensive: The price of the repair may be higher than the price of the vehicle, so that often the owner gives up repairing his car if he is not not properly insured.
- the invention solves this problem by means of a tool of the aforementioned type in which:
- the support element consists of an extensible frame comprising two parallel longitudinal members, this frame being equipped with means of attachment and / or suspension on the lateral reinforcements of the roof (roof) of the vehicle;
- the connecting element comprises a cross member movable in translation on the two longitudinal members of the support member;
- the backing element comprises a column, preferably adjustable in length, on one end of which can be fixed said actuator, and having at its other end, a movable carriage guided along said cross.
- the extensible frame can be disposed inside the vehicle and suspended on the lateral reinforcements of the flag, substantially parallel to it.
- the counter bearing element carrying the actuator equipped with a template can be brought to the right of each deformation by sliding the cross member along the longitudinal members and the carriage along the cross member.
- the actuator is then supplied with fluid under pressure to allow the template to return the sheet to its original shape.
- This process can be easily repeated to correct all deformations on the pavilion. Given the nature of the deformations produced by hail, this type of straightening is enough to bring the pavilion back to its original form without having to carry out additional treatment. The cost of repair is therefore considerably reduced and becomes acceptable, even in the case of a vehicle of low value.
- This solution makes it possible to straighten elements that can not be straightened using conventional tools. Of course, it can be used for other parts (including vertical) of the body of a vehicle.
- the support element may comprise means of attachment to the body such as a suction cup or even a permanent magnet (or even an electromagnet) and a column on which can slide and lock a carriage on which is articulated a lever with a handle.
- a lever which constitutes the aforesaid connecting element, is slidably mounted a counter-support element on which can be fixed an actuator optionally equipped with a template.
- the lever may be of any order.
- the connecting element may comprise two branches articulated by one of their ends, these two branches carrying at their other ends two support pieces, at least one of which constitutes a template, an actuator being arranged between the two branches so that they can be rotated around the hinge axis.
- Figure 1 is a schematic perspective view of an apparatus suitable for straightening deformations of a roof of a vehicle
- Figures 2 and 3 respectively show in cross section and in elevation an extensible cross member used in the embodiment illustrated in Figure 1;
- FIG. 4 represents an articulated extensible connecting element that can be mounted on a tabular structure
- Figure 5 is an alternative embodiment of an apparatus according to the invention using a circular magnet as a support member
- Figure 6 is a sectional view illustrating the mounting of an actuator on a counter ball support element
- Figure 7 shows an apparatus according to the invention involving a lever
- Figure 8 is an alternative embodiment of the apparatus according to the invention especially adapted to the recovery of the deformations of a vehicle wing;
- Figure 9 is a side view showing an apparatus involving two levers articulated to one another by one of their ends.
- the apparatus is more particularly intended to straighten deformations produced on a roof or vehicle roof, for example by large sized hail impacts.
- This apparatus involves an extensible frame 1 of square or rectangular shape intended to be arranged inside the vehicle, under the flag or the roof.
- the sides Ci to C 4 of the frame 1 each comprise two sections Ti, T 2 engaging telescopically one in the other, these sections Ti, T 2 can be tubular or even consist of section sections closed and / or open.
- Locking means may be used to lock the two sections making each side Ci -C 4 to the desired length.
- an extensible cross member TE On two opposite sides of the frame 1 is slidably mounted an extensible cross member TE on which slides a carriage 6, the length of the crossmember adapting to the dimensions of the frame.
- this crosspiece TE comprises two tubular sections 7, 8 of rectangular section which fit telescopically into a third tubular section 9, the outer section of the sections 7 and 8 being slightly smaller than the inner section of the third section 9.
- This crossbar can be removable and be used independently of the frame to support an actuator / template assembly used in locations such as, for example, inside a car door.
- the carriage consists, in turn, of a profile section 10 substantially C-shaped delimiting a section volume slightly greater than the outer section of the section 9.
- This profile section 10 is provided on its face (core) opposite its longitudinal opening 11, with a threaded rod 12 oriented perpendicularly to the plane of the frame 1, on which a column 13 carrying a pneumatic actuator 14 can be fixed. Even directly Pneumatic actuator.
- the face of the actuator 14 opposite the column 13 is itself provided with a rod 15 which extends coaxially with the column 13 and which supports a template 16 for the recovery of the flag.
- the attachment of the frame on the rigid structure of the vehicle is obtained by means of four hooks 17 to 20 respectively arranged at the four corners of the frame 1.
- hooks 17 to 20 are intended to be introduced into holes or edges present in the structure or made specifically for this purpose.
- the hooks 17 to 20 may be replaced by adjustable length rods, cables or even chains.
- the attachment of these rods, cables or chains on the fixed structure of the vehicle can be achieved by any means of attachment and / or known attachment.
- this equipment is particularly effective: Once the frame 1 installed in the vehicle, the operator can bring all actuator 14 / template 16 in a suitable location (under deformation) by moving the extensible cross member TE along the sides and the carriage 6 along the crosspiece TE. After having made a height adjustment of this assembly, it proceeds to an admission of gas under pressure, preferably compressed air, into the actuator 14. Under the effect of the gas pressure, the template 16 comes to exert push on the deformation until it resumes its original shape.
- gas under pressure preferably compressed air
- the crosspiece TE may be articulated so as to allow changes in the orientation of the actuator 14 and a better adaptation of the template to the shape of the sheet that is to be straightened.
- FIG. 4 shows a crosspiece TE 'comprising a central element formed by fitting two tubular sections 21, 22.
- the two ends of this central element are connected to guiding and / or fixing elements 23, 24 by the intermediate of two respective hinges 25, 26.
- These guiding and / or fixing elements 23, 24 consist of a U-shaped section section section, the two ends of which are provided with bores in which clamping screws engage. 27, 28.
- a carriage 29 for carrying an actuator 30, for example of the type previously described.
- the axial locking of this carriage 29 as well as that of the two tubular sections is ensured by means of respective knurled screw screws 31, 32.
- the guiding and / or fixing elements 23, 24 may be slidably mounted on the two parallel sides of a frame 1 of the type shown in FIG. 1 or even of a cradle, or even on the structure of the vehicle.
- the fixing in position of these guide elements 23, 24 on the frame or the cradle is obtained by tightening the screws 27, 28.
- the apparatus consists of an annular magnetized structure 34 (annular permanent magnet or one or more permanent magnets mounted on an annular structure).
- This annular element 34 carries a coaxial cylindrical drum 35 of outside diameter substantially equal to the inside diameter of the annular structure 34.
- This drum 35 comprises a bottom 36 and a circular opening 37 opposite the bottom 36, this opening 37 being situated at the level of the application face of the annular element 34.
- a bellows pneumatic cylinder 38 bearing on the bottom 36 and carrying, opposite the bottom 36, a rod 39 equipped with a jig 40 of circular shape provided with a face d 41 support slightly curved.
- the height adjustment of the template 40 is obtained thanks to the fact that the rod 39 is threaded in its lower part and is screwed into a threaded tubular sleeve 42 coaxial with the jack 38 and integral with the face thereof opposite the bottom.
- the annular element 34 is applied to the sheet, coaxially to the deformation 43.
- the template 40 After having optionally adjusted the position of the template 40 by screwing / unscrewing the rod 39 in the sleeve 42, it proceeds to a gas inlet pressure in the cylinder 38.
- the template 40 then exerts on the deformation 43 a force tending to straighten it. Because of its curved shape, the template 40 will bring the sheet slightly beyond its original position by creating within the sheet a tension likely to deploy any bends.
- the inlet of fluid under pressure in the cylinder 38 is interrupted, the part of sheet slightly convex (opposite the initial deformation), returns to its original position, thanks to its elasticity.
- the apparatus illustrated in FIG. 5 can be mounted on a frame like the actuator illustrated in FIG.
- the apparatus involves a lever 45, one end of which carries a handle 46 while the other end is hinged to a tubular sleeve 47 slidably mounted on a rod 48 integral with one of its ends, a suction cup 49 (or even a magnet or an electromagnet).
- a carriage 50 constituted by a tubular section on which can be fixed, via a fixing column 51, a pneumatic cylinder 52 carrying a template 53.
- the locking position of the trolley 50 on the lever 45 is provided by means of a needle screw 54 which is screwed into a threaded hole provided on the carriage 50.
- the suction cup 49 is fixed on a portion of sheet metal which may consist, but not necessarily, in the plate carrying the deformation.
- the actuator used in the previously described examples may be mounted on its support (counter-support element) via a ball joint.
- FIG. 6 This solution is illustrated in Figure 6 in which the cylinder 60 (bellows type) is mounted in a tabular body 61 at least partially closed on one side by a bottom 62 integral with one end of the cylinder 60.
- the other end of the cylinder 60 is extended by a threaded rod 63 emerging from the body 61 by a coaxial orifice and on which can be screwed a template 64.
- the bottom 62 carries a threaded coaxial tubular sleeve 65 in which the stem 66 of a ball joint 67 can be screwed to provide a ball joint connection with a support piece 68, which may for example consist of a carriage of the type of those used in the previous examples.
- the apparatus illustrated in FIG. 8 is specially designed to straighten deformations produced on a wing 70 of an automobile. It involves a lever 71 bent at right angles carrying at one end a handle 72 and at its other end, a template 73, possibly interchangeable (to adapt to the shape to straighten).

- an actuator 79 here an accordion cylinder, which acts on the arm 80 of the lever 71 carrying the jig 73.
- the cylinder 79 is then retracted.
- the operator tilts the lever 71 until the template 73 comes to bear on the wing 70 in the region where the deformation is located:
- the operator controls the activation of the cylinder 79 by holding the handle 72 until the deformed part is straightened.
- the previously described lever may be used without the jack or even without the support piece 75.
- the apparatus is in the form of an elongated clamp having two arms 81, 82 articulated to one another by one end (articulation 83). These two arms carry at their other ends two respective attachment means 84, 85 for receiving either a support element or a template (elements 86, 87).
- This clamp can be manipulated by a handle 88 carried by a third arm 89 articulated about the axis of the joint 83 of the arms 81, 82.
- a pneumatic actuator 90 consisting of an elastomeric balloon connected to a pressurized gas inlet circuit.
- this apparatus can be engaged in narrow passages, for example between the body sheet and the stiffeners associated with this sheet.
- the actuator may further comprise means for generating vibrations facilitating the return of the deformed sheet to its initial position.
