Definitions
- Multipurpose clamping device intended to hold objects without damaging them and its method of use.
- the present invention relates to a method for producing a multipurpose clamping device intended to hold objects without damaging them, such a device and its method of use.
- Known tools or jaws are used for clamping or assembling parts which generally consist of two jaws mounted on a support part serving as a guide, part along which can slide at least one of these jaws so as to be able to adjust their spacing according to the size of the part to be clamped or the parts to be assembled and / or held in position.
- Many devices such as notching, ratchet, screw, spring, hydraulic or the like are provided to maintain the relative position of the jaws and / or to exert pressure on the part or parts to be clamped or assembled .
- European patent EP 080 960 which corresponds to a prior request from the inventor, and which describes devices with orientable jaws, adaptable to any support to ensure stable clamping, assembly, spacing or holding pieces of any shape and size.
- the device represented in FIG. 4 of this European patent comprises:
- first movable arm itself constituting a first jaw element
- a helical compression spring guided around a second cylindrical piece called guide piece, connecting, parallel to the support piece, one of the ends of the second movable arm to a second jaw element. This is mounted idly at one end of said guide part and the other end of this crosses the end of the second movable arm in a sliding manner so as to be retained on the other side, by a pin, a pin, a clip or a key.
- the guide part can skew in the passage through which it crosses the second movable arm, in the latitude of the game necessary for its slide ent in said passage. This leads the second jaw element to shift laterally relative to the first jaw element, which can be annoying during a clamping operation.
- a helical spring as a means of elastic compression implies the use of several accessories such as a second jaw element (1a) (in addition to the movable arm (6)), a guide piece (2a ) and a pin (13), and to provide a passage for the guide part in said movable arm.
- the cost of these accessories and of making this passage obviously increases the cost price of the device and also its weight.
- the present invention consists, with regard to the device shown in Figure 4 of European Patent EP 080 960, to replace with a single part the assembly consisting of the spring, its guide part, means for retaining and sliding the latter and the second jaw member.
- This single piece is a substantially elastic pad, one of the faces of which rests on said movable arm and the opposite face of which is called the bearing face and is to be applied against the objects to be enclosed. We will see later that this replacement avoids any loss of function and creates new ones.
- Said pad is composed of a material substantially elastic such as natural or synthetic rubber, foam plastic, cotton. It can have a solid or spongy structure.
- Said bearing face is substantially flat or slightly in a bowl and its base is essentially orthogonal to said support piece.
- Said pad can take the form of a glued washer, a shutter fixed by a pin or a ring threaded on said movable arm at a distance from said support piece.
- a clamping device equipped according to the present invention comprises:
- cylindrical support piece such as a rod or a tube, not necessarily of circular section
- At least two movable arms capable of sliding along and taking several orientations around said support piece and each extending clearly on either side of it in an essentially orthogonal direction, at least one substantially elastic pad, which pad, on the one hand, is fixed on one of the arms at a distance from said support piece and, on the other hand, has opposite to the arm on which it is fixed, a bearing face, including the plate is essentially orthogonal to the support part.
- the invention can be conceived as a global production process comprising the following steps: a. supply of a cylindrical support part, such as a rod or a tube, not necessarily of circular section, b. mounting on said support part of at least two mobile arms capable of sliding along and taking several orientations around it, each of said movable arms extending clearly on either side of said support part in an essentially orthogonal direction, c. equipping at least one of said movable arms at a distance from said support part by a substantially elastic pad, the latter having, opposite the arm on which it is fixed, a bearing face, the base of which is essentially orthogonal to the support piece.
- a device according to the invention takes the name of "assembler" in the following description.
- the clamping operation of an assembler comprising only two movable arms, consists in pushing these, one towards the other, along the support piece, with the bearing face of the pad of one arm turned towards the other arm, and as soon as there is sufficient resistance to release the thrust.
- the arms are then blocked by tilting against said support piece like the ski-lift poles on their cable, whether or not there is something facing said buffer. To rule out, the principle is the same. With the movable arms turned over on the support piece, we act in reverse.
- the clamping operation is the same when the assembly piece of the assembler is partitioned into several parallel cylindrical elements, on the whole of which slide just two movable arms.
- the tightening operation differs in the approach of the movable arms, but the locking system remains the same.
- the first two arms are oriented around said support piece according to a V and they are pushed towards the next two, arranged substantially along the same V, roughly the pad of the first arm facing that of the third arm and the pad of the second arm facing that of the fourth arm.
- a third pair of mobile arms is added, each equipped with a substantially elastic pad to grasp, without damaging, objects to be paint or work with your hands free, you get a third hand called “vertical”.
- server we add a fourth, a fifth, etc ..., pairs of mobile arms, always mounted on the free part of the support piece, we successively obtain a fourth, a fifth, etc., "vertical" hands.
- Another auxiliary hand configuration can be obtained by mounting three pairs of movable arms one behind the other along said support piece, the movable arms of each pair being provided with substantially elastic pads whose bearing faces are turned. towards each other. Both first pairs of movable arms are separately locked by pad-to-pad clamping at one end of the support piece in two orientations differing by a non-zero angle which can be clearly above or below 90 °.
- the third pair of movable arms also constitutes a "server" for picking up objects to paint or to work with your hands free.
- the third hand thus obtained is called, in the remainder of the present application, the third "horizontal" hand because, resting on three feet - the buffers of the first two pairs of movable arms locked at one end of the support piece and the other end of it - it can be installed - anywhere on a roughly horizontal surface. If to this third pair is added a fourth, a fifth, etc., pairs of movable arms, always mounted on the remaining part of the support piece, one obtains successively a fourth, a fifth, etc., "horizontal" hands.
- a "server” can possibly be replaced by a rider.
- a coupler capable of grasping, in at least one direction distinct from that of said support piece, another support piece capable of carrying at least one movable arm equipped with a substantially elastic buffer.
- a coupler can consist of a cross-piece as there is in electricity in the form of studs. diversion, or in the navy or in a Mécano type construction set to ensure the crossing of two cables or halyards. It can also consist of a flexible strip of dominoes for electrical mounting which is kept curved, for example, by the way it is stowed on the first of said support pieces.
- the direction of the first of said support pieces makes an angle of approximately 90 ° with one of the other support pieces gripped by the coupler, it is possible to grip objects on three sides (T-clamping) or on four sides (clamping cross) between the movable arms carried by these two support parts.
- the coupler is capable of gripping several support pieces in directions all distinct from that of the support piece on which said coupler is stowed, it is possible to enclose objects from multiple sides between the movable arms carried by said support pieces.
- the tightening obtained is then called star tightening. Obviously said tightening, Tee, cross and star, can be done with movable arms arranged overlapping.
- the assembler according to the invention is versatile and that its general method of use, which makes it possible to hold objects by tightening without damaging them, consists of the following steps: a. enclosing said objects between substantially elastic pads carried by movable arms arranged along one or more cylindrical support pieces and capable of taking several orientations around them, b. apply a push on the back of said arms, in the direction of said objects, along said support pieces and release this push, so as to block each of said arms by tilting against the support piece on which it is disposed, vs. possibly using as support auxiliary objects placed in contact with substantially elastic pads carried by other mobile arms arranged and locked along said support parts.
- an additional characteristic can consist in that the ends of the support part are provided with removable end caps of the type clips, jumper, pin, key, pin, or section of flexible cylindrical sheath threaded by light forcing.
- Another possible characteristic is that one of said movable arms is replaced by a fixed arm.
- the first advantage of the invention resides in the fact that the tampon, by its substantial elasticity in the mass and by the capacity of its bearing face to match the contours of the gripping surfaces of the enclosed objects, achieves in one piece all the functions which hitherto fulfilled in synergy, in the device represented in FIG. 4 of European patent EP 080 960, the spring, the guide part, the means for retaining and sliding the latter on its support arm, and the second jaw element:
- the faces carried by the movable arms and which serve to press on the objects to be clamped are naturally held el astically facing one another during the clamping phase; the elastic retention allows them in addition to tilt to compensate for any defects in parallelism between the gripping surfaces of said objects and the movable arms;
- the clamping force is limited by the elastic erasure of the pad against the hard points; - moreover, thanks to the elasticity of the pad which slightly redefines, the play between the enclosed objects, play which a drying of glue can create, is caught up automatically;
- the elasticity of the buffer also makes it possible to absorb most of the shocks and vibrations to which objects enclosed may be subjected by any external action;
- the second advantage of the invention is that it is free from the defects which have been indicated above with regard to the device represented in FIG. 4 of European patent EP 080 960.
- the tampon creates a new function, in relation to all of the parts it replaces: avoiding the backsliding of the face to be supported by each movable arm on the objects to be gripped, which obviously results in making more safe the tightening operation.
- the third advantage of the invention is to be accompanied by the creation of all new functions: overlapping, which has been presented above and which would have been difficult to achieve with a device of the type shown in FIG. 4 of European patent EP 080 960, because of the tendency to shift from the guide rod of the spring; the third horizontal and vertical hands, generally capable of an arbitrary number of hands; star mounting.
- the servers which equip the auxiliary hands according to the invention do not risk with their substantially elastic pads of scratching the parts seized as the crocodile clips of traditional auxiliary hands can do with their teeth.
- these servers have their jaw elements which can open very widely while remaining parallel to each other.
- the auxiliary hands according to the invention are much lighter than traditional auxiliary hands, since they do not need a heavy base to maintain balance, even when the servers are loaded.
- Four of the movable arms mounted on the support piece are sufficient to ensure the seat of the auxiliary hand (see previous summary).
- the buffers of the first two pairs of movable arms locked by clamping at one end of the support piece produce with the other end thereof a lifting tripod. That is to say the generic power of the combination: cylindrical support piece, movable arms and substantially elastic pads.
- the fifth advantage of the invention is that by replacing the assembly consisting of the spring, the second jaw element, the guide rod with its means of retention and sliding on said second movable arm, the buffer constitutes at the same time a wedge of soft material, because substantially elastic. That is to say, it is useless to insert a plate of wood or other soft material between the pad and the gripping surface of the objects to be gripped, to spare it. This is appreciable because the insertion of shims is always an inconvenient operation.
- each movable arm equipped with a pad belonging to an assembler in the clamping or spacing position can support, against its side at the rear of said pad, under various incidences, the support of the buffer carried by one of the mobile arms of a second assembler.
- the second assembler can therefore, with the buffer of one of its other movable arms, force, in the clamping or spacing position, on a side of an object devoid of parallel opposite or on one of the buffers of a third assembler, also in the clamping or spacing position.
- This type of mounting makes it possible to overcome the absence of an easily grasped outline for holding enclosed objects, which is often the case with art objects to be restored.
- the seventh advantage of the invention is linked to the modularity of the assemblers which itself results from the mobility of the arms on the cylindrical support part. These can be slid out of their support piece (any end caps of these parts are removable) and installed on another support part, of the same section. Cylindrical support parts of the same section can be fixed in the extension of one another by couplers such as dominoes for electrical assemblies, sleeves for mechanical tubes or cable fittings. It does not matter that the couplers constitute barriers for the mobility of the arms between the different sections of support parts. It suffices to install a mobile arm on each of the two end sections and the opening between these mobile arms is necessarily greater than if these mobile arms were located on only one of the connected support parts.
- the maximum opening of the assemblers according to the invention becomes easily extendable, which contrasts sharply with traditional clamps where the fixing of one of the jaws at the end of the support piece makes it inconceivable the elongation thereof.
- all the original arrangements exposed can be produced under a large maximum opening. higher, such as overlap, auxiliary hands, etc.
- the eighth advantage of the invention is also linked to the mobility of the arms on the cylindrical support part.
- One of the movable arms of an assembler, comprising just two movable arms fitted with buffers, can be slid to the extreme end of the support piece fl
- an auxiliary bar such as a ruler or a tool handle
- a large surface for example, by means of the servers of two third vertical hands according to the invention gripping the two opposite edges of the large surface
- the assembler works as a spreader, it suffices for the buffer of its other mobile arm to buckle against the auxiliary bar.
- the assembler can go to exert pressure at any distance from the edge of a large area, which can be flat, curved, hollow or in tormented relief. It is enough that the auxiliary bar follows the contours of the surface, is sufficiently long and oriented in the right direction. For higher pressure, the two movable arms can be replaced by a rider in the spreading position.
- this type of mounting little known to those skilled in the art, was only possible with a special tool, a spacer very rare in workshops, and shims generally inconvenient to install.
- this assembly is easily and directly possible with the same assembler as that which allows all the other original assemblies previously described, with the possible addition of movable arms. This is what characterizes the versatility of the new assembler.

COMPOSITION AND MODES OF USE DETAILED OF THE EMBODIMENTS ACCORDING TO THE INVENTION
- a versatile tightening tool equipped according to the present invention therefore comprises in combination:
- cylindrical support piece (1) such as a rod or a tube, not necessarily of circular section
- At least one substantially elastic pad (3) which pad, on the one hand, is fixed on one of the arms (2) at a distance from said support piece (1) and, on the other hand, presents opposite the arm on which it is fixed, a bearing face, the base of which is essentially orthogonal to the support part.
- a complement may consist of adding to at least one of the two ends of said support piece, a stopper stopper (4) to prevent the movable arms (2) from being released from said support piece (1) when these are not retained on said part by any action.
- said pad (3) is composed of a flexible elastic material such as natural or synthetic rubber, foam plastic or cotton, and that its thickness under its bearing face is preferably greater. to the millimeter. It can have a solid or spongy structure. It can also consist of a hollow flat box with thin walls of wood, hard plastic or metal, which have the property of straightening when the pressure is reduced which is exerted on it.
- Said bearing face is substantially flat or slightly in a bowl and its base is essentially orthogonal to said support piece. For certain applications, said bearing face can nevertheless be curved.
- Said pad can take the form of a glued washer, a shutter fixed by a pin or a ring threaded on said movable arm at a distance from said support piece.
- a ring compared to a washer or a shutter, to constitute the buffer is that said ring can be fixed alone on said arm without requiring bonding or orifice formed in said arm. It suffices that its internal dimensions are slightly less than or equal to those of the external dimensions of said arm at the place where it is to be fixed, in order to be able to be force-fitted onto the arm at this location and to remain locked there.
- the buffer (3) is produced by a stack of substantially elastic washers, in the manner of springs composed of "Belleville" washers; in a first type of sub-embodiment, the washers are glued to the tail leu leu; in a second type of sub-embodiment, the washers are perforated and threaded, also at the tail leu leu, by forcing slightly, on a second cylindrical part parallel to said support part. Opposite the bearing face of said pad, said second cylindrical piece slides in a passage formed on the support arm of said pad, and is retained beyond this passage by a stopper stopper, similar to that which can be fitted the ends of said support piece (1).
- One of said means for allowing one of said movable arms (2) to slide along said support piece (1) consists of the provision of a through hole, the shape of which in internal section envelops in a small clearance close to the shape of the external section of said support piece (1).
- a stirrup attached to the side of said arm (2) said stirrup forming a loop
- another possibility is to form said through hole by making each of said straight arms (2) by assembling side by side two half-arms each provided, in the direction of their thickness, with a cylindrical groove provided with a section in half-moon, the hollow of the groove of one half-arm facing the hollow of the groove of the other half-arm for assembly
- a similar possibility is to provide on the flank of each entire arm, in the direction of its thickness, a cylindrical groove and to close it 1ongitudinally with a plate; one can also consider having a tenon portion of said arms wrapped by a hollow rail forming said support piece.
- each end-stopper (4) is constituted by a section of flexible tubular sheath whose diameter is slightly less than the average diameter of said support piece (1). Said section is threaded by light forcing at the end of said rod.
- Such end caps (4) can also consist of clips, jumpers, pins, keys or pins.
- using flexible sheath to be forced into a tube is a particularly economical means, since it makes it possible to avoid any machining of the support rod or tool to manufacture said end caps, which inevitably happens if the said rod has a non-standard section.
- Such a sheath is commonly found, because few constraints are required, barring exceptions, especially on the thermal side or on the aggressive side of the ambient environment. Only a diameter slightly smaller than the average diameter of the support rod and good conservation of elasticity over time are required, under ordinary environmental conditions. Can do flexible PVC, polyethylene tubes medium or low density, silicone, natural or synthetic rubber.
- Figure 1 shows an assembler according to the invention with just two movable arms (2).
- a single substantially elastic tampon (3) is used. It consists of a washer adhering to its movable arm (2) carrying, by gluing or by pin penetrated by force into an orifice formed in said arm (2).
- an assembler according to the invention comprising just two movable arms (2), two substantially elastic pads (3), one per arm, are used. They each consist of a washer adhering to its carrying arm (2), by gluing or by pin penetrated by force into an orifice formed in said arm (2).
- FIG. 3 also with an assembler according to the invention comprising just two movable arms (2), two substantially elastic pads (3), one per arm, are also used. But they each consist of a rubber ring or other equivalent plastic material or cellular structure, threaded in force on its support arm (2).
- the movable arms (2) then lock automatically and instantly against the support part, by tilting, like the poles of a ski lift on their cable.
- an assembler equipped according to the invention behaves like a real relay of the human hand or hands (in the sense of relaying), for the accomplishment of a task, such as tightening. It can indeed hold indefinitely a clamping position under the same effort that the hand or hands can hold temporarily.
- the spacing assembly with an assembler according to the invention comprising just two movable arms (2), operates in a similar manner. However, it is first necessary to turn the arms over said support piece, so as to present the bearing faces of said pads outwards. The objects to be removed are first brought to either side of the movable arms (2) of the tool, facing the bearing faces of the pads (3). The following operations are then identical to the operation of the tightening from the moment when the fingers or the palm of the hand begin to press on the back of said arms, except that the force to be perceived manually is that with which one wishes to spread.
- FIG. 5 a variant of the assembler comprising four movable arms, the first two (2a) and (2b) along the support piece (1) being fitted with substantially elastic pads. (3) with the bearing face facing the following two arms (2c) and (2d), these being fitted with substantially elastic pads with the bearing face facing in the opposite direction.
- the first two arms (2a) and (2b) are oriented around said support piece according to a V and they are opposite to the next two arms (2c) and (2d), arranged substantially according to the same V.
- the buffer (3 ) of the first arm (2a) faces that of the third arm (2c) and the pad of the second arm (2b) faces that of the fourth arm (2d).
- An intermediate configuration between the assembler according to the invention and the rider or super-assembler consists in using two mobile arms forming a V on one side of the clamping and only one mobile arm on the other. Depending on the relief of the surfaces to be captured, this configuration may prove to be sufficient.
- Figure 7 shows another auxiliary hand configuration: a fourth hand called “horizontal”. It is composed of four pairs of movable arms (2a) - (2b), (2c ;-( 2d), (2e) - (2f), (2g) - (2h), mounted one behind the other on along said support piece.
- the movable arms of each pair are fitted with substantially elastic pads (3) whose bearing faces are turned towards each other.
- the first two pairs of movable arms (2a) - (2b ) and (2c) - (2d) are separately blocked by clamping buffer against buffer at one end of the support piece in two orientations differing by an angle close to 70 °.
- the third pair (2e) - (2f) and the fourth pair (2g) - (2h) of movable arms constitute "servers" to grab objects to paint or to work hands free.
- the pads of the first two pairs of movable arms ( 2a) - (2b) and (2c) - (2d) blocked at one end of the support piece and the other end of it obviously forms a tripod.
- Each server can be used separately as an assembler with two movable arms for tightening and spacing operations.
- each "server” can possibly be replaced by a rider.
- FIG. 8 In FIG. 8 is shown a "star" arrangement.
- a flexible bar (5) of dominoes for electrical assemblies which has been curved.
- Said support part (1) carries two movable arms (2a) - (2b), both fitted with substantially elastic pads (3).
- Said bar (5) is curved because it is stowed on said support piece (1) by two studs (6) and (6a) normally spaced apart which have been brought together by twisting the bar in its mean plane . The screws of these studs are tightened on the support part (1), that is to say that they are blocked on the latter.
- the direction of the first support part (1) makes an angle of about 90 ° with that of the other support part (1a).
- the tightening operation for each pair of movable arms (2a) - (2b) and (2c) - (2d) is identical to that which is practiced for an assembler according to the invention with two movable arms. It is thus possible to enclose objects on four sides, as shown in Figure 8, between the movable arms carried by these two support parts.
- the tightening ot: enu is called cross tightening.
- coupler may consist of a spider comprising two or more channels which are divergent from each other and capable of holding the prisoner each by a screwing or other system, a rod or tube type support piece.
- This kind of spider exists in electricity in the form of bypass studs.
- Crossbars are also used in the navy and in construction sets of the Mechanic type to ensure the crossing of two cables or halyards.
- sheet metal or plastic to enclose electrical junction boxes.
- the bar as a coupler, can also be replaced by the forced hollow-on-hollow juxtaposition, in different orientations, of several profiles in the form of gutters similar to those which are used for the construction of exhibition stands or displays.
- the support part (1) is subdivided into several parallel cylindrical elements, which in fact constitute as many homogeneous parallel support parts. Said elements are made integral with each other at each of their ends by couplers which can be domino bars for electrical assemblies or equivalent when said elements have very similar diameters. At least one of the two said arms is sliding on these elements, the other being able to remain fixed on these elements.
- the two arms have a wide bearing face.
- the substantially elastic pad (3) carried by one or each of the two arms is made in one piece; in a second type of sub-embodiment, the substantially elastic tampon which one or each of the two arms carries is divided into several pieces; in this case, said pieces are located at the same distance from the mean plane in which the various cylindrical elements that make up are located said support piece; said pieces can be left free to act independently of one another or be sandwiched between the arm which carries them and a rigid connecting plate intended to play the role of jaws vis-à-vis the enclosed objects.
- the device according to the invention can find multiple applications such as the attachment of devices to a support when said device is made integral with one or constitutes one of said arms.
