Definitions
- the present invention relates to a method of making a versatile clamping device intended to hold objects without damaging them, such a device and its method of use.
- This hammer press which belongs to the category of tools tightening mentioned at the top of this state of the art review also blocks by friction, but its guide is only composed of a single rod and its jaws are substantially parallel to each other at rest.
- This hammer press is found, always offered in wood (generally captivating), in numerous commercial hardware catalogs, such as that of the house “Charbonnel fils” (in Thiviers in Dordogne, France) of 1910, figure 378 of plate 40, such as that of Establishments F. Guitel & Etienne Fromme united (rue Saint-Martin in Paris) of 1924, figure 2592 on page 232, and such as that of the Royal Forge (rue du Fau Kunststoff-Antoine, in Paris) of 1927, figure 306 of plate 32.
- the guide is only composed of a cylindrical rod
- one of the jaws is systematically fixed at the end of the rod and each of these is devoid of glides, cork or other, but has at the most away from the rod opposite the other jaw, by location where one could precisely stick a cork pad.
- this same hammer press with a jaw fixed at the end of the rod and a parallel jaw sliding on said rod, is presented on pages 27 and 28, relative to the figure 42, with cork pads at this location, by the cabinetmaking professor Trillat, in his book entitled "Le Guide Pratique du Métier ", printed by Fillet à Combe in Bourgouin (Isère, France).
- Pappas does not really stand out from the hammer press than by claiming a hanging system on the wall or on established from said press.
- the present invention differs from the state of the art previously mentioned in what consists in a process according to claims 1 and 10 and in a device according to claim 2.
- the new hammer press not only makes it possible to make a clamp, the only function of the hammer press so far, but also, by returning the jaws on the rod, spreader to go tighten in the recesses, and by adding jaws on said rod, rider, which is a new type of four-clamp spectacularly strong and stable clamping jaws, and different types of large multiple hands.
- couplers such as electrical connectors and repositioning the jaws accordingly, it is by elsewhere possible to significantly increase the opening maximum.
- couplers such as electrical connectors and repositioning the jaws accordingly, it is by elsewhere possible to significantly increase the opening maximum.
- couplers such as electrical connectors and repositioning the jaws accordingly, it is by elsewhere possible to significantly increase the opening maximum.
- it is also possible, with such connectors when they are multiple, laterally couple the stems in parallel to constitute multipoint vices, and to proceed to multidirectional tightening, possibly in chain, in bending the connector strips by short lashing on some of the stems.
- the present invention is then distinguished from the state of the art previously mentioned by replacing the classic skates of cork with elastic ring pads on all sides, but with a greater thickness on the side of the outer face support.
- the advantages of ring pads over skates cork are plentiful. First of all, there is no longer any need to fastening system, bonding, pin and hole type, for securing the pad or pad on the jaw. Then the ring pads can receive and laterally support other buffers equipping other jaws, which allows and facilitates all kinds of angle clamps, including for clamping workpieces whose contours are elusive. And of course, the ring pads are easily interchangeable, with ring pads with other profiles, to enter the rooms whose access is difficult for example.
- Thornton (US Patent 4,834,352) had envisaged for its tightening device with handle of the sheaths of completely surrounding protection, but under equal thickness, the end of the jaws.
- the purpose of these sleeves was to play the role of protective wedges, but not that of essential means for exert the clamping pressure which is played by a large spring in pin.
- the ring pads are the essential means for exerting the clamping pressure and, consistently, they present in the direction of clamping a greater thickness. This is what the ring pads of the present invention different from protective sheaths of Thornton. This difference is all the more marked as Thornton's apparatus virtually departs from the concept of hammer press.
- a device according to the invention takes the name of "assembler" in the following description.
- the tightening operation is the same when the support part of the assembler is partitioned into several elements parallel cylindrical, not distributed in the direction of the jaw length, as in Coffman, Ditto or Pappas, but in the orthogonal direction, and over all of which just slide two movable arms.
- movable arms For an assembler that includes just four movable arms can be oriented around said support piece in two directions forming a V, the first two along it being fitted with pads with the bearing face facing the two following arms, these being fitted with pads with the face support turned in the opposite direction, the tightening operation differs in approach to the movable arms, but the system of blocking remains the same.
- the first two arms are oriented around of said support piece according to said V and they are pushed towards the next two, arranged roughly 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 arms.
- the bearing faces of the pads are in contact with surfaces of enclosed objects and that sufficient strength is manifest, just release the push.
- Such a maneuver clamp has been given the name "overlap” and such a mounting of four movable arms on a cylindrical support piece received that of "rider” or “super-assembler”.
- the overlap can be also used to spread.
- the relative position of the arms stays the same except that these are returned on the coin support.
- An intermediate configuration between the assembler according to the invention and the rider or super-assembler is to use two movable arms forming said V on one side of the clamp and only one movable arm on the other. According to the relief of the surfaces to enter, this configuration may prove sufficient.
- 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.
- the first two 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 may be significantly 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 this application, third hand “horizontal” because, resting on three feet - the pads of the first two pairs of movable arms blocked 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, we obtain successively a fourth, a fifth, etc ..., hands “horizontal”. Note: For a firmer grip on one of the auxiliary hands previously considered, a "server" can possibly be replaced by a rider.
- a coupler capable of grasping, in at least a direction distinct from that of said support part, a other support piece capable of carrying at least one movable arm fitted with a substantially elastic pad.
- a coupler can consist of a cross like there exist in electricity in the form of branch pads, or in the marine or in construction set I type Mechanic to ensure the crossing of two cables or halyards. It can also consist in a flexible strip of dominoes for electrical mounting which is kept bent, for example, by the way it is stowed on the first of said support pieces.
- the management of the first of said support pieces makes an angle of approximately 90 ° with one of the other support parts gripped by the coupler, it is possible to enclose objects on three sides (tightening in Tee) or on four sides (cross clamping) between the movable arms that these two support pieces carry. And when the coupler is capable of gripping multiple support pieces in directions all distinct from that of the support piece on which said coupler is secured, it is possible to enclose objects of multiple sides between the mobile arms carried by said parts supports.
- the tightening obtained is then called star tightening. Obviously said tightening, in Tee, in cross and in star, can be done with movable arms arranged overlapping.
- Another faculty offered by the invention is linked also to the mobility of the arms on the cylindrical support part.
- One of the movable arms of an assembler comprising just two arms mobile equipped with buffers, can be slid at the end of the support piece (any end caps are removable).
- an auxiliary bar such as a ruler or a tool handle, is fixed parallel to a large area (for example, by means of servers of two third vertical hands according to the invention gripping the two opposite edges of the large surface), it is possible to press with the pad of this movable arm, in any which point of this surface, along this bar, without said support piece risks damaging said surface since it does not protrude from said movable arm.
- each movable arm when each movable arm is fitted with a ring buffer, is that the ring buffer belonging to an assembler in clamping or spacing position can bear, against its side, under various incidences, the support of the tampon carried by one of the mobile arms of a second assembler.
- the second assembler can therefore with the buffer of one of his other arms movable, force, in the clamping or spacing position, on a side of object not facing parallel or on one of the pads a third assembler, also in the clamping position or spacing.
- This type of assembly makes it possible to get rid of the absence of an easy-to-grasp outline to hold objects enclosed, which is often the case with works of art restore.
- This assembly was until now very difficult to carry out with the traditional clamps because of important wedges and basic, always awkward; to install and sometimes long to find, had to be stuck under the jaws. In general, it needed more than two hands and squeeze like a bully, and this can be incompatible with the solidity of the objects to be enclosed.
- This mounting becomes elementary, even under low clamping force, with the new assembler, thanks to the pads substantially elastic. It received the name angle clamping, clamping by stapling or bridging, depending on the number of assemblers it puts to ensure a better seat, the support assembler can optionally be replaced by a rider.
- an additional feature may consist in that the ends of the support piece are provided removable end caps, clips, jumper, pin, key, pin, or section of cheerful flexible cylindrical thread by light forcing.
- a complement may consist of the addition to at least one of the two ends of the said support piece, a stopper (4) to prevent the movable arms (2) to free themselves from said support piece (1) when these are not retained on said part by a any action.
- said pad (3) is composed of a material flexible elastic like natural rubber or synthetic, foam plastic or cotton, and that its thickness under its bearing face is preferably greater than a millimeter. It can have a solid or spongy structure. It can also be consisting of a hollow flat box with walls thin in wood, hard plastic or metal, which have the property of straightening when pressure is reduced that is exercised on it.
- Said support face is substantially flat or slightly in a bowl and its plate is essentially orthogonal to said piece support. For certain applications, said face support can nevertheless be curved.
- Said buffer can take the form of a glued washer, a shutter fixed by a pin or a ring threaded on said arm movable at a distance from said support part.
- 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 require bonding or orifice provided in said arms. It is enough that its internal dimensions are slightly less than or equal to those of external dimensions of said arm where it must be fixed, to be able to be forced into the arms there and get stuck there.
- the buffer (3) is achieved by a stack of washers substantially elastic, like springs composed of "Belleville” washers; initially type of underachievement, the washers are glued to the tail leu leu; in a second type of sub-realization, the washers are perforated and threaded, also at the tail leu leu, forcing slightly, on a second cylindrical part parallel to said support piece. Opposite the bearing face of said buffer, said second cylindrical part slides in a passage formed on the support arm of said pad, and is retained beyond this passage by a stopper, similar to that which can equip the ends of said support piece (1).
- One of said means for enabling one of said movable arms (2) to slide along said part support (1) is constituted by the arrangement of a hole passage, whose internal cross-sectional shape to a small clearance near the shape of the external section of said support piece (1).
- a stirrup attached to the side said arm (2), said stirrup forming a loop
- another possibility is to form said through hole in making each of said straight arms (2) by side-by-side assembly of two half-arms each provided, in the direction of their thickness, a groove cylindrical with a half-moon section, the hollow of the groove of a half-arm facing the hollow of the groove of the other half-arm for assembly
- a neighboring possibility is to spare on the side of each entire arm, in the direction of its thickness, a cylindrical groove and close it longitudinally by a plate; can also consider having a tenon part wrapped said arms by a hollow rail forming said part support.
- each stopper (4) consists of a section of sheath flexible tubular 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.
- use flexible sheath to put on in force on a tube is a particularly economical, because it avoids any machining of the support rod or tool for manufacturing said end caps, which inevitably happens if said rod to a non-standard section.
- Such a gay is not commonly found, because few constraints are required, with some exceptions, especially on the thermal side or on the aggressive side of the environment. Only are required a slightly smaller diameter than the medium diameter of the support rod and a good conservation of elasticity over time, in ordinary environmental conditions. Can do the case of flexible PVC, polyethylene tubes medium or low density, silicone, rubber natural or synthetic.
- Figure 1 shows an assembler according to the invention with just two movable arms (2).
- One substantially elastic pad (3) is used. he consists of a washer adhering to its movable arm (2) carrier, by gluing or by pin penetrated in force in an orifice formed in said arm (2).
- 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 force as the hand (s) can hold temporarily.
- the spacing maneuver with an assembler according to the invention comprising just two movable arms (2), operates from analogously. However, you should first return the arms to said support piece, so as to present the bearing faces of said pads to the outside. The objects to be removed are first brought to either side of the arms mobile (2) of the tool, facing the bearing faces of the pads (3). The sequence of operations is then identical to the maneuver 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 at perceiving manually is the one with which we wish to rule out.
- FIG. 5 shows a variant of the assembler comprising four movable arms, the first two (2a) and (2b) along the support piece (1) being equipped with substantially elastic pads (3) with the bearing face facing the two arms following (2c) and (2d), these being fitted with buffers substantially elastic with the bearing face turned in the opposite direction.
- the first two arms (2a) and (2b) are oriented around said part support according to a V and they are opposed to the two arms following (2c) and (2d), arranged substantially according to the same V. Roughly the tampon (3) of the first arm (2a) faces that of the third arm (2c) and the tampon of the second arm (2b) faces that of the fourth arm (2d).
- Figure 7 shows another auxiliary hand configuration: a fourth hand called “horizontal”. It is made up 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 equipped with substantially elastic buffers (3), the bearing faces of which are turned towards one another.
- the first two pairs of movable arms (2a) - (2b) and (2c) - (2d) are separately locked by pad-to-pad clamping at one end of the support part 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 work on. 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 the latter obviously form a tripod.
- Each server can be used separately as an assembler with two movable arms for tightening and spacing operations. Note: For a firmer grip on the auxiliary hands shown, each "server" can possibly be replaced by a rider.
- FIG. 8 is shown an assembly "in star ".
- a flexible strip (5) of dominoes for assemblies that has been bent.
- 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 s said support piece (1) by two studs (6) and (6a) normally distant who have been reconciled one of the other by twisting the bar in its mean plane. The screws of these studs are tightened on the support piece (1), i.e. they are stuck on it.
- Another coupler model can consist of a cross with two channels or more divergent from each other and able to retain each imprisoned by a screwing system or another, a rod or tube type support piece.
- This kind of cross exists in electricity in the form of bypass studs.
- the barette, as that coupler can still be replaced by juxtaposition forced hollow on hollow, in different orientations, of several profiles in the form of gutters similar to those which are used for the construction of exhibition stands or display stands.
- the support part (1) is subdivided into several parallel cylindrical elements, which in fact constitute as many parallel support parts homogeneous. Said elements are made integral with each other others at each of their ends by couplers which can be domino bars for electrical assemblies or equivalent when said elements have very large diameters neighbors. At least one of the two said arms is sliding on these elements, the other being able to remain fixed on these elements. Both arms have a wide support face.
- the substantially elastic buffer (3) that carries one or each of the two arms consists of a single piece; in a second type of sub-realization, the buffer substantially elastic that one or each of the two arms carries is split into several pieces; in this case, said pieces are located at the same distance from the middle plane in which are the various cylindrical elements that make up said support piece; said pieces can be left free to act independently of one another or be sandwiched between the arm that carries them and a rigid connecting plate intended to play the role bit vis-à-vis enclosed objects.
- the device according to the invention can find multiple applications such as attaching devices to a support when said device is made integral with one or constitutes one of said arms

Description
Nota: Pour une prise plus ferme sur une des mains auxiliaires précédemment considérées, un "serveur" peut éventuellement être remplacé par un chevaucheur.
- Tout d'abord, les serveurs qui équipent les mains auxiliaires selon l'invention ne risquent pas avec leurs tampons substantiellement élastiques de griffer les pièces saisies comme peuvent le faire avec leurs dents les pinces crocodiles des mains auxiliaires traditionnelles.
- Par ailleurs, à la différence des pinces crocodiles, ces serveurs ont leurs éléments de mâchoires qui peuvent s'ouvrir très largement tout en restant parallèles l'un à l'autre.
- Enfin, les mains auxiliaires selon l 'invention sont nettement plus légères que les mains auxiliaires traditionnelles, puisqu'elles se passent de socle lourd pour tenir l'équilibre, même lorsque les serveurs sont chargés. Quatre des bras mobiles montés sur la pièce support suffisent à assurer l'assise de la main auxiliaire (voir sommaire précédent). Dans le cas des mains auxiliaires verticales, ils sont combinés en chevaucheur pour s'agripper sur le rebord d'un établi ou d'une table. Dans le cas des mains auxiliaires horizontales, les tampons des deux premières paires de bras mobiles bloquées par serrage à une extrêmité de la pièce support réalisent avec l'autre extrêmité de celle-ci un trépied sustentateur. C'est dire la puissance générique de la combinaison: pièce support cylindrique, bras mobiles et tampons substantiellement élastiques.
- la figure 1 est une vue en élévation d'un assembleur selon l 'invention à deux bras mobiles dont l'un est équipé d'un tampon en forme de rondel le;
- la figure 2 est une vue en élévation d'un assembleur selon l'invention à deux bras mobiles équipés chacun d'un tampon en forme de rondelle;
- la figure 3 est une vue en élévation d'un assembleur selon l'invention à deux bras mobiles équipés chacun d'un tampon en forme de bague;
- la figure 4 est une vue en élévation d'une utilisation possible du dispositif conforme à la figure 2 selon l'invention;
- la figure 5 est une vue en perspective d'un assembleur selon l'invention à quatre bras mobiles montés en "chevaucheur" et équipés chacun d'un tampon en forme de bague;
- la figure 6 est une vue en perspective d'un assembleur selon l'invention à six bras mobiles montés en troisième main verticale et équipés chacun d'un tampon en forme de bague;
- la figure 7 est une vue en perspective d'un assembleur selon l'invention à huit bras mobiles montés en quatrième main horizontale et équipés chacun d'un tampon en forme de bague;
- la figure 8 est une vue en perspective d'un assembleur selon l'invention dont la pièce support est porteuse de deux bras mobiles et sur laquelle est arrimé un coupleur saisissant dans une direction distincte de celle de ladite pièce support, une autre pièce support portant deux autres bras mobiles équipés chacun d'un tampon substantiellement élastique;
- une pièce support (1) cylindrique, telle qu'une tige ou un tube, pas forcément de section circulaire,
- au moins deux bras mobiles (2) capables de glisser le long et de prendre plusieurs orientations autour de ladite pièce support (1) et s 'étendant chacun nettement de part et d'autre de celle-ci dans une direction essentiellement orthogonale,
- au moins un tampon substantiellement élastique (3), lequel tampon, d'une part, est fixé sur un des bras (2) à distance de ladite pièce support (1) et, d'autre part, présente à l'opposé du bras sur lequel il est fixé, une face d'appui, dont l'assiette est essentiellement orthogonale à la pièce support.
- amener l'ensemble des objets (8-9), à enserrer, entre les bras (2) de l'outil, en regard des faces d'appui des tampons substantiellement élastiques (3);
- appuyer avec les doigts ou la paume de la main sur le dos des bras, à l'opposé desdites faces d'appui , le long de la pièce support (1), en direction desdits objets (8-9); les bras (2) coulissent alors le long de ladite pièce support; dès que lesdites faces d'appui touchent les surfaces de saisie desdits objets (8-9), les doigts perçoivent une résistance, celle des objets, comme s'ils appuyaient directement sur lesdits objets;
- continuer à appuyer sur le dos des bras (2) en augmentant la pression pour comprimer les tampons;
- dès que la main ressent avoir atteint la force qui suffit à serrer convenablement lesdits objets l'un contre l'autre, arrêter d'appuyer; les bras mobiles (2) se bloquent alors automatiquement et instantanément contre la pièce support, par basculement, comme les perches d'un remonte-pente sur leur câble.
Nota: Pour une prise plus ferme sur les mains auxiliaires représentées, chaque "serveur" peut éventuellement être remplacée par un chevaucheur.
