Description

L'invention concerne un dispositif de serrage du type serre-joint.The invention relates to a tightening device type clamp.

Les serre-joints peuvent présenter diverses formes selon les applications visées.The clamps may have various shapes depending on the intended applications.

A cet égard, on distingue notamment trois familles, le serre-joint dit de menuisier, le serre-joint dit de maçon, et celui dit de coffrage.In this regard, there are three particular families, the so-called joiner joiner, the said clamp mason, and the so-called formwork.

Ces serre-joints ont tous en commun, une tige ou barre rectiligne, un valet ou mors fixe solidaire de l'une des terminaisons de la barre et s'étendant sensiblement perpendiculairement à la barre, ainsi qu'un valet mobile ou coulisseau perpendiculaire à la barre et monté coulissant sur celle-ci, chacun des valets étant doté à son extrémité libre d'une tête de serrage à butée plate en vis-à-vis. La pièce à serrer est destinée à être placée entre les valets respectivement fixe et mobile, le valet mobile étant déplacé vers le valet fixe jusqu'à maintenir serrée la pièce entre les deux têtes de serrage.These clamps all have in common, a rod or straight bar, a jack or fixed jaw secured to one of the ends of the bar and extending substantially perpendicular to the bar, and a movable jack or slide perpendicular to the bar and slidably mounted thereon, each of the valets being provided at its free end with a flat stop clamping head vis-à-vis. The piece to be clamped is intended to be placed between the valets respectively fixed and movable, the movable valet being moved towards the fixed valet until keeping tight the part between the two clamping heads.

Le serre-joint de menuisier est doté, sur le coulisseau, d'une tête de serrage spécifique dit à serrage par vis, la tête de serrage du coulisseau étant apte à être également mobile en translation parallèlement à la barre du serre-joint une fois le coulisseau agencé en position fixe. Le vissage de la tête mobile permet un serrage contrôlé.The joiner's clamp has, on the slide, a specific tightening head said clamping screw, the clamping head of the slide being adapted to be also movable in translation parallel to the bar of the clamp once the slider arranged in a fixed position. The screwing of the movable head allows a controlled tightening.

Plus particulièrement, la tête de serrage mobile du serre-joint de menuisier est agencée à l'extrémité libre du coulisseau. Elle est composée d'un élément de butée (nommé coupelle) dont la surface d'application est de préférence de forme circulaire, et d'une broche filetée s'étendant perpendiculairement au coulisseau et parallèlement à la barre du serre-joint, et coopérant avec un alésage taraudé disposé à l'extrémité libre supérieure du coulisseau. La broche filetée comporte à l'une de ses extrémités la coupelle, et à son extrémité opposée, un manche à pièce fixe ou à levier de serrage permettant de visser ou dévisser la broche filetée afin de rapprocher la tête de serrage de la pièce ou objet à serrer.More particularly, the movable clamping head of the joiner clamp is arranged at the free end of the slider. It is composed of an abutment element (called cup) whose application surface is preferably of circular shape, and a threaded spindle extending perpendicularly to the slide and parallel to the bar of the clamp, and cooperating with a threaded bore disposed at the upper free end of the slide. The threaded spindle comprises at one of its ends the cup, and at its opposite end, a handle with a fixed part or with a clamping lever enabling the threaded spindle to be screwed or unscrewed so as to bring the clamping head closer to the part or object to tighten.

Le serre-joint de maçon présente quant à lui les particularités suivantes :

  • Le valet fixe est de forme courbe à la manière d'une canne, avec sa concavité tournée vers le valet opposé mobile. Le cintrage du bras permet d'échapper des pièces ou obstacles de la construction pour laquelle est utilisé le serre-joint ;
  • le coulisseau est en forme de L ; il est destiné à coulisser sur la barre jusqu'à proximité de l'objet à serrer dont le serrage est finalisé par frappe sur la tête de serrage du coulisseau. Le coulisseau en L présente sa grande branche perpendiculaire à la barre et dotée d'un orifice traversant pour sa coopération avec la barre, tandis que la petite branche solidaire de l'extrémité de la grande branche, opposée à la barre, est orthogonale à la grande branche et est dotée de la tête de serrage à surface plane.
The Mason clamp has the following characteristics:
  • The fixed valet is curved in the manner of a cane, with its concavity facing the mobile opposite valet. The bending of the arm makes it possible to escape parts or obstacles of the construction for which the clamp is used;
  • the slider is L-shaped; it is intended to slide on the bar until close to the object to be tightened, the tightening is finalized by striking on the clamping head of the slide. The L-shaped slider has its large branch perpendicular to the bar and has a through hole for its cooperation with the bar, while the small branch secured to the end of the large branch, opposite the bar, is orthogonal to the large branch and has the flat-surface clamping head.

Enfin, le serre-joint de coffrage qui présente des fonctionnalités similaires au serre-joint de maçon, possède néanmoins des caractéristiques propres :

  • le valet fixe est agencé parfaitement orthogonalement à la barre rectiligne afin de former un équerrage ;
  • le valet fixe est renforcé et présente une longueur plus importante que pour les autres serre-joints;
  • la tête de serrage du coulisseau comporte une platine de surface relativement large afin de se plaquer correctement contre et parallèlement à une plaque de coffrage destinée à être serrée. Ainsi, chaque serre-joint présente une forme particulière et des caractéristiques dédiées à sa fonction.
Finally, the shuttering clamp, which has similar features to the mason's clamp, nevertheless has its own characteristics:
  • the fixed valet is arranged perfectly orthogonal to the straight bar to form a squareness;
  • the fixed valet is reinforced and has a greater length than for the other clamps;
  • the clamping head of the slider comprises a plate of relatively large surface in order to press properly against and parallel to a shuttering plate intended to be clamped. Thus, each clamp has a particular shape and features dedicated to its function.

Or, cela impose à l'utilisateur qui oeuvre dans plusieurs corps de métier d'avoir à disposition chacun des types de serre-joint. On connaît par ailleurs du document US2008/086852 un serre-joint qui par des bras pivotants en extrémité du valet fixe et du coulisseau peut fournir plusieurs possibilités de serrage.However, this requires the user who works in several trades to have available each type of clamp. It is also known from the document US2008 / 086852 a clamp which by pivoting arms at the end of the fixed jack and the slider can provide several clamping possibilities.

L'invention a donc pour but de proposer un outil de serrage du type serre-joint qui réunit toutes les fonctionnalités des serre-joints précités en un unique dispositif.The invention therefore aims to provide a clamping type clamping tool that combines all the features of the aforementioned clamps into a single device.

Selon l'invention, le dispositif de serrage du type serre-joint comporte une barre rectiligne, un valet fixe solidaire de la barre et s'étendant selon une direction générale X perpendiculaire à la barre, et un coulisseau apte à coulisser le long de la barre, le valet fixe comportant un bras apte à adopter une position droite en prolongement rectiligne de la direction générale X du valet fixe ou au moins une position inclinée par rapport à l'axe X en direction du coulisseau et le coulisseau comportant une tête de serrage, caractérisé en ce que le dispositif comporte une platine amovible apte à être montée sur la tête de serrage du coulisseau.
Ainsi, le même dispositif peut être utilisé en tant que serre-joint de menuisier ou de maçon en position inclinée du bras, ou bien serre-joint de coffrage en position droite du bras.According to the invention, the tightening device of the type clamp-seal comprises a straight bar, a fixed jack fixed to the bar and extending in a general direction X perpendicular to the bar, and a slider able to slide along the bar, the fixed jack having an arm adapted to adopt an upright position in rectilinear extension of the general direction X of the fixed jack or at least one position inclined with respect to the X axis in the direction of the slider and the slider comprising a clamping head , characterized in that the device comprises a removable plate adapted to be mounted on the clamping head of the slide.

Les figures 1 et 3 illustrent un dispositif de serrage de l'invention en vue de différentes utilisations de serre-joint, respectivement de menuisier ou de maçon, et de coffrage.The Figures 1 and 3 illustrate a clamping device of the invention for different uses clamp, respectively joiner or mason, and formwork.

L'illustration de la figure 4 peut également servir en tant que serre-joint de maçon.The illustration of the figure 4 can also be used as a mason clamp.

La figure 2 illustre le dispositif avant la configuration de la figure 3 en tant que serre-joint de coffrage (avant modification de la tête de serrage du coulisseau).The figure 2 illustrates the device before configuring the figure 3 as formwork clamp (before modification of the slide clamping head).

En regard des figures 1 à 4, le dispositif de serrage 1 de l'invention comporte une barre rectiligne ou rail 2, un valet fixe 3 associé à la barre 2 et doté d'un bras 5 amovible et/ou mobile, un valet mobile ou coulisseau 4 apte à être déplacé en translation le long de la barre 2, en particulier en direction du valet fixe 3 lorsqu'il s'agit de serrer un objet, ici non représenté, entre ledit valet fixe 3 et ledit coulisseau 4.With regard to Figures 1 to 4 , the clamping device 1 of the invention comprises a straight bar or rail 2, a fixed valet 3 associated with the bar 2 and provided with a movable and / or movable arm 5, a movable jack or slider 4 adapted to be moved in translation along the bar 2, in particular in the direction of the fixed valet 3 when it is a matter of tightening an object, not shown here, between said fixed valet 3 and said slider 4.

Le valet fixe 3 est doté de deux surfaces distinctes d'applique 6 et 7 destinées à recevoir indépendamment en butée l'objet à serrer selon l'utilisation qui est faite du serre-joint et telle que vue plus loin.The fixed valet 3 is provided with two separate surfaces of applique 6 and 7 intended to receive independently abutting the object to be clamped according to the use that is made of the clamp and as seen below.

Chaque surface d'applique et de butée 6, 7 présente en commun une zone plane d'applique et de butée 60, respectivement 70, en regard du coulisseau 4. Cependant, la disposition de chaque surface d'applique, sa géométrie et sa hauteur de positionnement par rapport à la barre 2 diffèrent selon les utilisations. La surface d'applique 6 est associée à l'extrémité libre 50 du bras 5, tandis que l'autre surface d'applique 7 est associée au corps général 30 du valet.Each surface of applied and abutment 6, 7 has in common a flat area of applied and abutment 60, respectively 70, opposite the slider 4. However, the disposition of each surface of applique, its geometry and its height positioning relative to the bar 2 differ according to the uses. The surface of application 6 is associated with the free end 50 of the arm 5, while the other surface of application 7 is associated with the general body 30 of the jack.

Quant au coulisseau 4, il est pourvu d'une tête de serrage 8 qui est agencée en regard du valet fixe 3 et destinée à être amenée par serrage contre l'objet à bloquer. Là encore selon l'invention et telle que vue plus loin, la tête de serrage 8 présente au moins deux configurations distinctes quant à sa surface d'applique et de pression selon l'utilisation qui est faite du serre-joint.As for the slider 4, it is provided with a clamping head 8 which is arranged facing the fixed valet 3 and intended to be brought by clamping against the object to be blocked. Again according to the invention and as seen below, the clamping head 8 has at least two distinct configurations as to its surface of application and pressure according to the use that is made of the clamp.

En regard de la figure 1, la première surface d'applique 6 à l'extrémité du bras 5 et la tête de serrage 8 forment des mors respectivement fixe et mobile pour un serre-joint de menuisier.With regard to the figure 1 , the first surface of application 6 at the end of the arm 5 and the clamping head 8 form respectively fixed and movable jaws for a joiner joiner.

En regard de la figure 2, la première surface d'applique 6 à l'extrémité du bras 5 et la tête de serrage 8 avec adaptation de la surface de pression de ladite tête forment des mors respectivement fixe et mobile pour un serre-joint de maçon.With regard to the figure 2 , the first surface of application 6 at the end of the arm 5 and the clamping head 8 with adaptation of the pressure surface of said head form jaws respectively fixed and movable for a mason clamp.

En regard de la figure 3, la seconde surface d'applique 7 du corps 30 du valet fixe et la tête de serrage 8 avec adaptation de la surface de pression de ladite tête forment des mors respectivement fixe et mobile pour un serre-joint de coffrage.With regard to the figure 3 , the second surface of application 7 of the body 30 of the fixed valet and the clamping head 8 with adaptation of the pressure surface of said head form jaws respectively fixed and movable for a formwork clamp.

La barre rectiligne 2 est de configuration usuelle pour les serre-joints. Sa longueur est par exemple de 50 ou 100 cm. Elle présente deux terminaisons opposées 20 et 21.The straight bar 2 is of usual configuration for the clamps. Its length is for example 50 or 100 cm. It has two opposite endings 20 and 21.

Le valet fixe 3 comporte un corps général 30 d'axe longitudinal X-X orthogonal à la direction longitudinale de la barre 2. Le corps du valet comporte deux extrémités distales opposées 31 et 32, l'une des extrémités 31 étant rendue solidaire de l'une des terminaisons 20 de la barre 2.The fixed valet 3 comprises a general body 30 of longitudinal axis XX orthogonal to the longitudinal direction of the bar 2. The body of the valet has two opposite distal ends 31 and 32, one end 31 being secured to one endings 20 of the bar 2.

Le corps général 30 du valet fixe 3, de l'une à l'autre des extrémités 31 et 32, présente une certaine hauteur, par exemple de l'ordre de 150 mm par rapport à la face supérieure 22 de la barre 2.The general body 30 of the fixed valet 3, from one to the other of the ends 31 and 32, has a certain height, for example of the order of 150 mm with respect to the upper face 22 of the bar 2.

Selon l'invention, le valet fixe 3 comporte un bras 5 articulé sur le corps général 30 du valet, de préférence à la seconde extrémité distale 32 dudit corps opposée à la barre 2, le bras 5 étant apte à adopter plusieurs positions angulaires par rapport à la direction X-X.According to the invention, the fixed valet 3 comprises an articulated arm 5 on the general body 30 of the valet, preferably at the second distal end 32 of said body opposite the bar 2, the arm 5 being able to adopt several angular positions relative to each other. in direction XX.

Le bras présente une longueur par exemple de l'ordre de 130 à 150 mm, tel que 135 mm.The arm has a length for example of the order of 130 to 150 mm, such as 135 mm.

Dans les exemples représentés sur les figures, seules deux positions angulaires sont adoptées.In the examples shown in the figures, only two angular positions are adopted.

Plus particulièrement, tel qu'illustré sur les figures 1 et 4, le bras 5 peut présenter une inclinaison avec le corps 30 du valet 3 selon un angle intérieur α par exemple de l'ordre de 120°. Une telle position sera nommée par la suite « position inclinée ».In particular, as illustrated in figures 1 and 4 , the arm 5 may have an inclination with the body 30 of the valet 3 at an inner angle α for example of the order of 120 °. Such a position will be named later "inclined position".

En regard des figures 2 et 3, un angle intérieur α de 180° est établi de sorte que le bras 5 se situe dans le prolongement du corps 30 du valet fixe 3, selon l'axe X-X. Cette position sera ci-après nommée « position droite ». Le bras 5 forme une extension du valet 3.With regard to Figures 2 and 3 an internal angle α of 180 ° is set so that the arm 5 is in the extension of the body 30 of the fixed valet 3, along the axis XX. This position will hereafter be called "right position". The arm 5 forms an extension of the jack 3.

Les deux positions angulaires (respectivement inclinée et droite) sont obtenues par des moyens de positionnement et de verrouillage en position 1A, qui seront décrits plus loin. Lesdits moyens sont ici conçus pour adopter l'une ou l'autre des deux positions. En variante, ils pourraient être adaptés afin d'offrir des positions angulaires supplémentaires.The two angular positions (respectively inclined and right) are obtained by positioning and locking means in position 1A, which will be described later. Said means are here designed to adopt one or other of the two positions. Alternatively, they could be adapted to provide additional angular positions.

Le bras 5 est de préférence rendu solidaire du corps 30 du valet fixe 3 mais pourrait être amovible. Le bras 5 forme un corps allongé aux extrémités proximale 50 et distale inférieure 51. L'extrémité 50 du corps du bras est libre et porte sur sa tranche la surface d'applique 6, tandis que l'extrémité opposée 51 est associée au bras 3.The arm 5 is preferably secured to the body 30 of the fixed valet 3 but could be removable. The arm 5 forms an elongate body at the proximal 50 and lower distal 51 ends. The end 50 of the arm body is free and bears on its edge the applicator surface 6, while the opposite end 51 is associated with the arm 3 .

Tel que représenté, le bras 5 est relié à l'extrémité distale 32 du corps 30 du valet 3. En variante, le bras 5 pourrait être connecté à une autre partie du corps du valet que l'extrémité distale 32, telle qu'une partie proximale, imposant alors une hauteur de positionnement différente pour la surface d'applique 6 liée audit bras. La longueur du corps 30 du valet, l'endroit de connexion du bras 5 sur le valet 3 et l'angle d'inclinaison du bras 5 imposent à la surface d'applique 6 sa hauteur par rapport à la barre 2, ce qui permet par conséquent de s'adapter à la hauteur de l'objet à serrer.As shown, the arm 5 is connected to the distal end 32 of the body 30 of the valet 3. Alternatively, the arm 5 could be connected to another part of the valet body than the distal end 32, such as a proximal portion, then imposing a different positioning height for the surface of applique 6 connected to said arm. The length of the body 30 of the jack, the place of connection of the arm 5 on the jack 3 and the angle the angle of inclination of the arm 5 impose on the surface of application 6 its height relative to the bar 2, which therefore allows to adapt to the height of the object to be clamped.

Dans le mode de réalisation de l'invention illustré sur les figures et plus particulièrement visible sur la figure 5, le corps 30 du valet fixe 3 comporte deux flasques parallèles 30A et 30B espacés qui permettent de ménager un espace médian protégé pour loger les moyens de positionnement et de verrouillage 1A.In the embodiment of the invention illustrated in the figures and more particularly visible on the figure 5 , the body 30 of the fixed valet 3 comprises two parallel flanges 30A and 30B spaced which allow to provide a median space protected to accommodate the positioning and locking means 1A.

Afin d'établir les différentes positions angulaires du bras 5, ledit bras est fixé au valet 3 de manière pivotante via un axe de pivotement 33 agencé dans un plan transversal à l'axe X-X. L'axe de pivotement 33 est transversal et solidaire des deux flasques 30A et 30B.In order to establish the different angular positions of the arm 5, said arm is fixed to the valet 3 pivotally via a pivot axis 33 arranged in a plane transverse to the axis X-X. The pivot axis 33 is transverse and integral with the two flanges 30A and 30B.

Si le bras 5 était amovible, les différentes positions angulaires pourraient être obtenues soit par pivotement par rapport à une position de montage du bras 5 sur le valet 3, soit par coopération du bras 5 sur le valet 3 selon différentes positions de montage.If the arm 5 was removable, the various angular positions could be obtained either by pivoting with respect to a mounting position of the arm 5 on the valet 3, or by cooperation of the arm 5 on the valet 3 in different mounting positions.

En regard de la figure 5, la surface d'applique 6 du bras 5 est formée par une zone plate 60 de la tranche de l'extrémité libre 50 du corps du bras. A titre d'exemple, pour des raisons de simplicité de fabrication du bras 5, tout en lui procurant une résistance aux forces de serrage destinées à s'appliquer contre la surface d'applique 6, transversalement à la zone plate 60, ledit bras comporte deux pièces identiques longilignes 52 et 53 rivetées l'une contre l'autre. Chaque pièce 52, respectivement 53, comprend une âme allongée 52A, respectivement 53A, formant le corps général du bras, et une aile terminale pliée en équerre 52B, respectivement 53B, les ailes 52B et 53B s'étendant dans des directions opposées. Les ailes 52B et 53B sont coplanaires et forment la surface d'applique 6 à surface plate 60.With regard to the figure 5 , the surface of application 6 of the arm 5 is formed by a flat area 60 of the edge of the free end 50 of the body of the arm. By way of example, for the sake of simplicity of manufacture of the arm 5, while providing it with a resistance to the clamping forces intended to be applied against the surface of application 6, transversely to the flat zone 60, said arm comprises two identical elongate pieces 52 and 53 riveted one against the other. Each piece 52, respectively 53, comprises an elongated core 52A, respectively 53A, forming the general body of the arm, and an end wing folded at right angles 52B, respectively 53B, wings 52B and 53B extending in opposite directions. The wings 52B and 53B are coplanar and form the surface of application 6 with flat surface 60.

Lorsque le bras 5 est en position inclinée par rapport au corps 30 du valet (figure 1 correspondant au serre-joint de menuisier et figure 2 correspondant au serre-joint de maçon), la surface d'applique 6 est sensiblement parallèle à et en vis-à-vis de la tête de serrage 8 du coulisseau 4.When the arm 5 is in an inclined position relative to the body 30 of the jack ( figure 1 corresponding to the joiner joiner and figure 2 corresponding to the masonry clamp), the surface of application 6 is substantially parallel to and vis-à-vis the clamping head 8 of the slider 4.

L'angle d'inclinaison du bras 5 et la longueur du bras sont adaptées pour être à hauteur de la tête de serrage 8, par exemple selon une hauteur par rapport à la face supérieure 22 de la barre de 185 mm.The angle of inclination of the arm 5 and the length of the arm are adapted to be at the height of the clamping head 8, for example at a height relative to the upper face 22 of the bar of 185 mm.

En regard de la figure 3 correspondant au serre-joint de coffrage, la surface d'applique 7 du bras 3 est agencée en regard du coulisseau 4, et à hauteur du corps 30 en débutant au niveau de la barre 2 pour former un équerrage avec ladite barre 2. Cette surface d'applique 7 s'étend de préférence sensiblement sur toute la hauteur du corps 30. Elle est formée, à titre d'exemple, par des retours transversaux 34A et 34B à partir des flasques 30A et 30B. Ces retours 34A et 34B sont avantageusement de directions opposées pour constituer une surface d'applique suffisamment large. Ces retours sont à surface plane 70 pour former une surface d'applique plane. A titre d'exemple, cette surface correspond à une hauteur de 140 mm par 45 mm de largeur.With regard to the figure 3 corresponding to the formwork clamp, the surface of application 7 of the arm 3 is arranged opposite the slider 4, and at the height of the body 30 by starting at the bar 2 to form a squareness with said bar 2. This surface Applied 7 preferably extends substantially over the entire height of the body 30. It is formed, for example, by transverse returns 34A and 34B from the flanges 30A and 30B. These returns 34A and 34B are advantageously in opposite directions to form a sufficiently wide surface area. These returns are flat surface 70 to form a planar surface. By way of example, this surface corresponds to a height of 140 mm by 45 mm of width.

Ainsi, en regard d'un serre-joint de coffrage, la surface d'applique 7 fait un angle de 90° avec la barre 2 et le bras 5 permet de prolonger cette surface d'applique, la face interne 54 du corps du bras 5 étant plane et coplanaire avec la surface d'applique 70, ce qui permet d'obtenir une surface idoine pour un serre-joint de coffrage (à angle droit et suffisamment grande, par exemple de 285 mm au regard des autres dimensions précitées).Thus, facing a shuttering clamp, the surface of application 7 makes a 90 ° angle with the bar 2 and the arm 5 allows to extend this surface of application, the inner face 54 of the body of the arm 5 being planar and coplanar with the surface of application 70, which allows to obtain a suitable surface for a shuttering clamp (at right angles and large enough, for example 285 mm with respect to the other dimensions mentioned above).

De manière usuelle, le coulisseau 4 comporte un corps 40 s'étendant transversalement à la barre 2. Le corps 40 comporte :

  • une extrémité distale 42 pourvue de la tête de serrage 8
  • et une extrémité proximale 41 dotée d'un orifice 43 pour le passage de la barre 2.
In the usual manner, the slider 4 comprises a body 40 extending transversely to the bar 2. The body 40 comprises:
  • a distal end 42 provided with the clamping head 8
  • and a proximal end 41 having an orifice 43 for the passage of the bar 2.

L'orifice 43 est dimensionné afin que le coulisseau 4 puisse coulisser le long de la barre. Le coulisseau est bloqué en position lorsque la tête de serrage 8 est serrée contre l'objet à bloquer.The orifice 43 is dimensioned so that the slider 4 can slide along the bar. The slider is locked in position when the clamping head 8 is clamped against the object to be blocked.

La tête de serrage 8 illustrée sur la figure 1 est usuelle pour les serre-joints, en particulier de menuisier. Elle comporte en regard des figures 1 et 7, une broche filetée 80 coopérant avec un alésage cylindrique taraudé 81 solidaire de l'extrémité 42 du coulisseau 4, une coupelle 82 formant le mors mobile et solidaire de l'une des extrémités de la broche, et un levier de manoeuvre 83 agencé à l'extrémité opposée de la broche pour visser et dévisser la broche filetée 80 et ainsi actionner la translation du mors 82 vers le bras 3 et par conséquent vers l'objet à serrer.The clamping head 8 illustrated on the figure 1 is common for clamps, especially carpenter. It has next to figures 1 and 7 a threaded spindle 80 cooperating with a threaded cylindrical bore 81 integral with the end 42 of the slider 4, a cup 82 forming the movable jaw and secured to one end of the spindle, and an operating lever 83 arranged at the end of the spindle, opposite end of the pin to screw and unscrew the threaded spindle 80 and thus actuate the translation of the jaw 82 to the arm 3 and therefore to the object to be clamped.

De préférence, la broche filetéè 80 est de manière connue à double-filet.Preferably, the threaded spindle 80 is in a known double threaded manner.

La coupelle 82 est à section circulaire du côté de sa face de serrage 84 destinée à être appliquée par pression sur l'objet à serrer. Cette même face 84 est avantageusement crantée sur sa périphérie pour renforcer l'accroche avec l'objet à serrer.The cup 82 has a circular section on the side of its clamping face 84 intended to be applied by pressure on the object to be clamped. This same face 84 is advantageously notched on its periphery to strengthen the grip with the object to be clamped.

Selon la figure 7, la coupelle 82 est de manière connue avantageusement montée articulée sur et autour d'une rotule 85 en saillie de l'extrémité de la broche 80, autorisant son inclinaison dans toutes les directions autour de la broche 80.According to figure 7 , the cup 82 is in a known manner advantageously mounted articulated on and around a ball 85 projecting from the end of the pin 80, allowing its inclination in all directions around the pin 80.

Selon l'invention, le serre-joint étant destinée à être utilisé en maçonnerie, la broche filetée 80 (figure 9) comporte avantageusement sur sa paroi externe deux méplats opposés, dont un méplat 86 est visible sur la figure. Ces méplats permettent de casser et d'ôter le béton lors du desserrage, béton qui a pu se solidifier sur la broche.According to the invention, the clamp being intended to be used in masonry, the threaded spindle 80 ( figure 9 ) advantageously comprises on its outer wall two opposite flats, a flat portion 86 is visible in the figure. These flats make it possible to break and remove the concrete when loosening, concrete that could solidify on the spit.

Selon l'invention, en regard de la figure 3, un accessoire supplémentaire 9 du dispositif peut être ajouté à la coupelle 82 de la tête de serrage 8 selon l'utilisation qui est faite du serre-joint, en particulier pour un serre-joint de coffrage, de façon à augmenter l'aire de la surface de serrage de ladite tête.According to the invention, with regard to the figure 3 an additional accessory 9 of the device can be added to the cup 82 of the clamping head 8 according to the use made of the clamp, in particular for a formwork clamp, so as to increase the working area. the clamping surface of said head.

Cet accessoire 9 (figures 3, 6 et 8) consiste en une platine montée amovible sur ladite tête de serrage 8, cette platine présentant une face 90 à surface plane destinée à former la surface de pression et de serrage du mors mobile. La face 90 de forme sensiblement rectangulaire procure une surface d'applique et de pression équivalente à celle d'un mors de serre-joint de coffrage de l'art antérieur.This accessory 9 ( figures 3 , 6 and 8 ) consists of a plate removably mounted on said clamping head 8, this plate having a flat surface surface 90 for forming the pressure and clamping surface of the movable jaw. The face 90 of substantially rectangular shape provides a surface of application and pressure equivalent to that of a formwork clamp jaw of the prior art.

Ainsi, cette platine 9 est disposée sur la coupelle 82 de la tête de serrage 8 lorsque le dispositif 1 est utilisé en tant que serre-joint de coffrage (figure 3).Thus, this plate 9 is disposed on the cup 82 of the clamping head 8 when the device 1 is used as a formwork clamp ( figure 3 ).

En regard de la figure 6, la platine 9 est associée de manière amovible à la coupelle 82 en coopérant de préférence par emboîtement. En regard de la figure 6, la face 91 de la platine rectangulaire, opposée à la face 90 formant la surface d'applique, comporte une glissière de fixation 92 formée par deux retours latéraux et longitudinaux 93 et 94. La glissière 92 s'étend d'une extrémité libre 96 de la platine jusqu'à son extrémité libre opposée 97, avantageusement selon un section conique.With regard to the figure 6 , the plate 9 is removably associated with the cup 82 cooperating preferably by interlocking. With regard to the figure 6 , the face 91 of the rectangular plate, opposite the face 90 forming the surface of application, comprises a fixing slide 92 formed by two lateral and longitudinal returns 93 and 94. The slide 92 extends from a free end 96 from the plate to its opposite free end 97, advantageously in a conical section.

La glissière 92 présente une largeur se rétrécissant depuis une zone proximale 95 de la platine en direction de l'une des extrémités 97. L'extrémité 96 de plus grande largeur est plus large que le diamètre de la coupelle 82, tandis que la zone proximale présente une largeur équivalente au diamètre de la coupelle. Cette zone proximale 95 de rétrécissement est située, en position montée verticale de la platine, juste au-dessus de la zone médiane de la platine pour un maintien sûr par gravité de la platine.The slide 92 has a narrowing width from a proximal zone 95 of the plate towards one of the ends 97. The wider end 96 is wider than the diameter of the cup 82, while the proximal zone has a width equivalent to the diameter of the cup. This proximal zone 95 of narrowing is located, in the vertical mounting position of the plate, just above the central zone of the plate for safe holding by gravity of the plate.

Le montage de la platine 9 sur la coupelle 82 se fait de la manière suivante : la platine 9 est amenée au niveau de la tête de serrage 8 en introduisant l'extrémité la plus large 96 de la glissière autour de la coupelle 82, puis en exerçant un action de poussée de la platine vers la coupelle et de poussée de l'extrémité 96 la plus large vers l'extrémité opposée 96, la platine 9 glisse autour de la coupelle 82 selon un mouvement de translation longitudinale jusqu'à se bloquer sur coupelle au niveau de la zone proximale rétrécie 95 de la glissière. La platine est alors fermement maintenue en place sur la coupelle.The mounting of the plate 9 on the cup 82 is as follows: the plate 9 is brought to the level of the clamping head 8 by introducing the widest end 96 of the slide around the cup 82, then exerting a thrust action of the plate towards the cup and pushing the widest end 96 towards the opposite end 96, the plate 9 slides around the cup 82 in a longitudinal translation movement until it locks on cup at the narrowed proximal zone 95 of the slideway. The platen is then firmly held in place on the cup.

Pour faciliter le repérage du sens d'association de la platine, une flèche peut être marquée sur la platine, telle qu'illustrée. La flèche peut par exemple être inscrite sur la surface de la platine ou même découpée dans l'épaisseur de la platine.To make it easier to identify the association direction of the deck, an arrow can be marked on the deck as shown. The arrow can for example be inscribed on the surface of the plate or even cut in the thickness of the plate.

Avantageusement, la platine 9 amovible peut être rangée sur le dispositif lorsqu'elle n'est pas utilisée (voir figure 4). La platine 9 coopère également par emboîtement avec la seconde surface d'applique 7 du valet fixe 3. La largeur de la seconde surface d'applique 7 est bien entendue adaptée aux dimensions de la glissière 92 de la platine.Advantageously, the removable plate 9 can be stored on the device when it is not in use (see figure 4 ). The plate 9 also cooperates by interlocking with the second surface of application 7 of the fixed valet 3. The width of the second surface of application 7 is of course adapted to the dimensions of the slide 92 of the plate.

Les moyens de positionnement et de verrouillage du bras 5 sont à présents décrits en regard des figures 10a à 10c.The positioning and locking means of the arm 5 are now described with regard to Figures 10a to 10c .

Ces moyens de positionnement et de verrouillage consistent à titre d'exemple nullement limitatif en un mécanisme 1A comprenant un cliquet de manoeuvre 10 coopérant avec le bras 5 et un ressort de rappel 12, combiné à une butée 13 contre laquelle est bloqué le bras en position. L'ensemble est logé entre les deux flasques 30A et 30B.These positioning and locking means consist by way of non-limiting example in a mechanism 1A comprising an operating pawl 10 cooperating with the arm 5 and a return spring 12, combined with a stop 13 against which the arm is locked in position . The assembly is housed between the two flanges 30A and 30B.

Le cliquet 10 présente un doigt d'arrêt 14 coopérant avec l'extrémité inférieure 51 du bras 5. L'extrémité inférieure 51 présente une géométrie adaptée pour la coopération avec le doigt 14, ici en présentant :

  • d'une part un décrochement 55 sur la tranche de l'extrémité 51 du bras formant une cavité dans laquelle se loge l'extrémité distale du doigt d'arrêt 14 dans la position inclinée du bras (figure 10a) ;
  • d'autre part un épaulement 56 formé à l'extrémité inférieure 51, par la face externe longitudinale 57 du bras, et venant en applique contre la face interne latérale 15 du doigt 14, en position droite dudit bras (figure 10b).
The pawl 10 has a stop finger 14 cooperating with the lower end 51 of the arm 5. The lower end 51 has a geometry adapted for cooperation with the finger 14, here by presenting:
  • on the one hand a recess 55 on the edge of the end 51 of the arm forming a cavity in which the distal end of the stop finger 14 is housed in the inclined position of the arm ( figure 10a );
  • on the other hand a shoulder 56 formed at the lower end 51, by the longitudinal outer face 57 of the arm, and coming into application against the lateral internal face 15 of the finger 14, in the right position of said arm ( figure 10b ).

Le cliquet présente en outre une partie d'actionnement 16 agencée à l'opposé du bras 5. Celle-ci fait légèrement saillie hors du corps 30 du valet 3 (figure 1) pour assurer sa préhension et aisément appuyer dessus. De plus, cette partie d'actionnement 16 comprend une surface supérieure 17 légèrement incurvée pour l'emplacement du pouce.The pawl further has an actuating portion 16 arranged opposite the arm 5. The latter protrudes slightly from the body 30 of the valet 3 ( figure 1 ) to ensure its grip and easily press on it. In addition, this actuating portion 16 includes an upper surface 17 slightly curved for the location of the thumb.

Le cliquet est apte à être mobile en pivotement autour d'un axe 18, solidaire et transversal aux deux flasques 30A et 30B.The pawl is adapted to be movable in pivoting about an axis 18, integral and transverse to the two flanges 30A and 30B.

La face inférieure 19 du cliquet repose sur le ressort de rappel 12. Dans la position droite ou inclinée du bras 5, le cliquet 10 est en position de repos ne sollicitant pas le ressort 12. Lors du changement de la position inclinée à celle droite, il est nécessaire de basculer le cliquet, ce qui comprime le ressort 12 (figure 10c). Une fois en position inclinée le ressort de rappel 12 ramène automatiquement en position de repos le cliquet 10, dont le doigt 14 se bloque alors dans la cavité 55 du bras.The lower face 19 of the pawl rests on the return spring 12. In the straight or inclined position of the arm 5, the pawl 10 is in the rest position not biasing the spring 12. When changing from the inclined position to the right one, it is necessary to tilt the pawl, which compresses the spring 12 ( figure 10c ). Once in an inclined position the return spring 12 automatically returns to the rest position the pawl 10, the finger 14 then hangs in the cavity 55 of the arm.

Enfin, la butée 13 est située à l'extrémité supérieure du corps 30 du valet 3, par exemple est formé d'un axe reliant les deux flasques 30A et 30B. Cette butée permet d'arrêter les positions inclinée et droite du bras 5 en coopérant avec la face longitudinale externe 57 du bras 5.Finally, the stop 13 is located at the upper end of the body 30 of the jack 3, for example is formed of an axis connecting the two flanges 30A and 30B. This stop makes it possible to stop the inclined and right positions of the arm 5 by cooperating with the external longitudinal face 57 of the arm 5.

L'agencement de la butée, en particulier la distance la séparant de la tranche interne des flasques 30A et 30B (surface d'applique 7), est adaptée par rapport à l'épaisseur du bras 5 de sorte qu'en position droite (figure 10b) le bras butant sur celle-ci présente sa face interne longitudinale 54 coplanaire avec la surface d'applique 7.The arrangement of the stop, in particular the distance separating it from the inner edge of the flanges 30A and 30B (surface of application 7), is adapted with respect to the thickness of the arm 5 so that in the upright position ( figure 10b ) the arm abutting on it has its inner longitudinal face 54 coplanar with the surface of applique 7.

Le fonctionnement du mécanisme est le suivant :

  • Lorsque le bras 5 est en position inclinée (figure 10a), on appuie d'une main sur la surface d'actionnement 17 du cliquet 10 pour faire pivoter ledit cliquet, ce qui comprime le ressort 12 et permet de dégager le doigt 14 hors de la cavité 55 (figure 10c) et de l'autre main on fait pivoter le bras jusqu'à sa position droite.
  • Dès que le doigt 14 est dégagé, il est alors possible de relâcher le cliquet 10 qui revient à sa position initiale. Le bras 5 est amené en position droite jusqu'à être arrêté par la butée 13 (figure 10b). Le dispositif peut alors être utilisé en tant que serre-joint de coffrage.
  • Pour disposer le bras de la position droite à inclinée, il suffit d'appuyer sur la face externe 57 du bras 5 pour le faire basculer, engendrant le pivotement du cliquet du fait que la pointe 56A de l'épaulement 56 vient appuyer sur la face latérale interne 14 du doigt du cliquet. Le bras 5 est basculé jusqu'à se bloquer en position, la face longitudinale externe 57 venant buter contre la butée 13. Le cliquet étant sollicité par le ressort de rappel 12 à revenir en position de repos, un fois le bras 5 stoppé, le doigt 14 du cliquet vient s'engager dans la cavité 55 du bras. Le dispositif peut alors être utilisé en tant que serre-joint de maçon ou de menuisier.
The operation of the mechanism is as follows:
  • When the arm 5 is in an inclined position ( figure 10a ) is pressed with one hand on the actuating surface 17 of the pawl 10 to rotate said pawl, which compresses the spring 12 and allows to release the finger 14 out of the cavity 55 ( figure 10c ) and the other hand is rotated the arm to its upright position.
  • As soon as the finger 14 is released, it is then possible to release the pawl 10 which returns to its initial position. The arm 5 is brought into the upright position until stopped by the stop 13 ( figure 10b ). The device can then be used as a formwork clamp.
  • To position the arm from the straight to the inclined position, it suffices to press on the outer face 57 of the arm 5 to tilt it, causing the pawl to pivot, because the point 56A of the shoulder 56 presses on the face internal lateral 14 of the ratchet finger. The arm 5 is tilted until it locks in position, the external longitudinal face 57 abuts against the abutment 13. The pawl being urged by the return spring 12 to return to the rest position, once the arm 5 is stopped, the finger 14 of the pawl is engaged in the cavity 55 of the arm. The device can then be used as a mason or joiner's clamp.

Enfin, le dispositif comporte avantageusement une poignée de préhension 35 ménagée dans le corps 30 du valet 3, de préférence selon un orifice oblong découpé dans chacun des flasques 30A et 30B.Finally, the device advantageously comprises a handle 35 formed in the body 30 of the valet 3, preferably according to an oblong hole cut in each of the flanges 30A and 30B.

Par conséquent, le bras amovible et/ou mobile du valet fixe, le bras comprenant une surface d'applique et de butée, procure plusieurs alternatives de serre-joints selon la position du bras par rapport au corps général du valet fixe, la position droite correspondant à un serre-joint de coffrage, tandis que la position inclinée correspond à un serre-joint de menuisier ou de maçon.Therefore, the removable arm and / or movable fixed valet, the arm comprising a surface of apply and stop, provides several alternatives clamps according to the position of the arm relative to the general body of the fixed valet, the right position corresponding to a clamp of formwork, while the inclined position corresponds to a joiner joiner or mason.

La longueur du bras et l'angle d'inclinaison sont adaptés pour travailler en serre-joint de maçon ou de menuisier, en particulier pour procurer :

  • en position inclinée du bras, le dégagement nécessaire à serrer une pièce de maçonnerie et équivalent à la concavité de la canne d'un serre-joint usuel de maçon ; et
  • une hauteur idoine entre la barre et un plan passant par le mors fixe et mobile, ici à titre d'exemple une hauteur type de 185 mm ; et
  • en position droite du bras, un prolongement du corps du valet fixe pour une hauteur totale particulièrement adaptée quant à un serre-joint de coffrage.
The length of the arm and the angle of inclination are suitable for working in mason or joiner's clamps, in particular to provide:
  • in the inclined position of the arm, the clearance required to clamp a piece of masonry and equivalent to the concavity of the cane of a conventional mason clamp; and
  • a suitable height between the bar and a plane passing through the fixed and mobile jaw, here as an example a typical height of 185 mm; and
  • in the right position of the arm, an extension of the body of the fixed valet for a total height particularly suitable for a clamp formwork.

De plus, en maçonnerie, pour augmenter la surface de pression et de serrage du mors mobile du serre-joint, la platine amovible utile pour le serre-joint de coffrage peut également être utilisée sur le mors mobile.In addition, in masonry, to increase the pressure and clamping surface of the movable jaw of the clamp, the removable plate useful for the shuttering clamp can also be used on the movable jaw.
