DISPOSITIF DE SERRAGE EN FORME D'EPINGLE
La présente invention a pour objet un dispositif de serrage en forme d'épingle.PIN-SHAPED TIGHTENING DEVICE
The present invention relates to a pin-shaped clamping device.
I1 est destiné à serrer les uns contre les autres, deux ou plusieurs éléments, tels que par exemple des règles de maçon ou des planches de coffrage de part et d'autre d'un mur en construction, ou tout autre ensemble demandant à être serré provisoirement. I1 is intended to clamp against each other, two or more elements, such as for example mason's rulers or formwork boards on either side of a wall under construction, or any other assembly requiring to be tightened temporarily.
Dans la maçonnerie traditionnelle, pour maintenir des règles ou des planches de coffrage de chaque côté du sommet d'un mur en construction, on utilise généralement des presses à vis ou des serre-joints à frapper. Les premiers, faisant appel à un pas de vis plus ou moins fin, peuvent voir leur fonctionnement entravé dans une ambiance de chantier où ils sont soumis à des projections d'eau, de ciment, ... Les seconds ont l'inconvénient de nécessiter, pour leur mise en position de serrage, des chocs assez violents exécutés au marteau, qui risquent fort de déstabiliser le mur encore trop fraîchement édifié. In traditional masonry, to maintain rulers or formwork boards on each side of the top of a wall under construction, one generally uses screw presses or clamps to strike. The first, using a more or less fine screw pitch, can see their functioning hampered in a building site atmosphere where they are subjected to splashes of water, cement, ... The second have the disadvantage of requiring , for their setting in the clamping position, fairly violent shocks executed with a hammer, which are likely to destabilize the wall still too freshly built.
D'autre part, l'espace dégagé entre le niveau du point de serrage et le dessous de la barre de liaison des deux pinces est souvent très réduit et ne permet pas de travailler à l'aise sous cette barre.On the other hand, the space cleared between the level of the clamping point and the underside of the connecting bar of the two clamps is often very small and does not allow working at ease under this bar.
Enfin, pour un bon fonctionnement ultérieur, ces différents appareils nécessitent un nettoyage minutieux après chaque usage.Finally, for proper subsequent operation, these various devices require careful cleaning after each use.
L'invention a pour but de remédier à ces différents inconvénients en proposant un dispositif simple et fiable, facile à mettre en oeuvre, permettant par exemple de serrer fortement mais sans les écraser, deux règles ou deux éléments de coffrage sur le haut d'un mur de largeur donnée, tout en dégageant un espace important audessus du point de serrage. The invention aims to remedy these various drawbacks by proposing a simple and reliable device, easy to implement, allowing for example to tighten strongly but without crushing, two rules or two formwork elements on the top of a wall of given width, while leaving a large space above the clamping point.
I1 est constitué d'une épingle faisant ressort et ayant la forme d'un U renversé. Les deux branches verticales, évasées vers le bas, sont reliées par un étrier coulissant qui les rapproche l'une de l'autre lorsqu'on le fait descendre. A chacun des deux angles supérieurs du U renversé est fixé un levier, qui appuie à son autre extrémité sur l'étrier pour le pousser vers le bas. I1 consists of a spring pin and having the shape of an inverted U. The two vertical branches, flared down, are connected by a sliding stirrup which brings them closer to each other when it is lowered. At each of the two upper corners of the inverted U is attached a lever, which presses the caliper at its other end to push it down.
Sur les dessins annexés, donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention:
- la figure 1 représente le dispositif dans son ensemble en position de serrage, c'est à dire fermé,
- la figure 2 représente le même dispositif en position ouverte,
- la figure 3 représente l'étrier vu en plan,
- la figure 4 représente un des leviers vu en coupe verticale.In the accompanying drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention:
FIG. 1 represents the device as a whole in the clamping position, that is to say closed,
FIG. 2 represents the same device in the open position,
FIG. 3 represents the stirrup seen in plan,
- Figure 4 shows one of the levers seen in vertical section.
Le corps même du dispositif est constitué d'un ressort, par exemple en acier de type corde à piano , auquel on a donné la forme approximative d'un U renversé dont les branches (1) s'ouvrent vers le bas et sont terminées par des embouts (2) constitués par des retours à angle droit. Les angles supérieurs du U , où sont fixés d'un côté les leviers (4), peuvent être constitués par des boucles (5) comme dans le mode de réalisation présenté ici
En position ouverte, figure 2, l'étrier (3) est remonté vers le haut et la position des deux leviers (4) rappelle celle d'un V . Les embouts (2) sont éloignés des éléments à serrer.The very body of the device consists of a spring, for example of steel of the piano string type, to which the approximate shape of an inverted U has been given, the branches (1) of which open downward and are terminated by end caps (2) formed by right angle returns. The upper corners of the U, where the levers (4) are fixed on one side, can be constituted by loops (5) as in the embodiment presented here.
In the open position, FIG. 2, the stirrup (3) is raised upwards and the position of the two levers (4) recalls that of a V. The end caps (2) are distant from the elements to be tightened.
Lors de la mise en place du dispositif, celui-ci est saisi par chacune de ses branches (1) et les embouts (2) sont présentés au point où doit s'effectuer le serrage, généralement des trous percés dans les éléments à serrer, permettant de positionner l'appareil de manière précise. When the device is put in place, it is grasped by each of its branches (1) and the end pieces (2) are presented at the point where the tightening is to be carried out, generally holes drilled in the elements to be tightened, for positioning the device precisely.
Tenues verticalement, les branches (1) sont rapprochées l'une de l'autre, ce qui a pour effet de libérer l'étrier (3) qui tombe de lui même, donnant ainsi un premier serrage minimum. Ce serrage s' avère suffisant pour maintenir le dispositif en place et libérer les mains qui peuvent alors aller actionner les leviers (4) pour effectuer le serrage proprement-dit. Les leviers (4) ont basculé lors de la descente de l'étrier (3) et forment maintenant avec les branches du dispositif, un angle plus fermé (position en pointillé sur la figure 2), propice à une bonne prise en main. Celle-ci s'effectue en emprisonnant une branche verticale (1) et un levier (4) entre, d'une part le pouce et la paume de la main et, d'autre part, les quatre autres doigts, comme pour serrer n importe quelle pince.Held vertically, the arms (1) are brought closer to each other, which has the effect of releasing the stirrup (3) which falls by itself, thus giving a first minimum tightening. This tightening proves to be sufficient to hold the device in place and free the hands which can then actuate the levers (4) to carry out the actual tightening. The levers (4) tilted during the descent of the stirrup (3) and now form with the branches of the device, a more closed angle (dotted position in Figure 2), conducive to a good grip. This is done by trapping a vertical branch (1) and a lever (4) between, on the one hand the thumb and the palm of the hand and, on the other hand, the other four fingers, as if to tighten n no matter what clamp.
Grâce à la contraction, simultanée ou alternée, des deux mains, les leviers (4) prennent une position pratiquement verticale, parallèle aux branches (figure 1) et obligent ainsi l'étrier (3) à descendre plus bas, conférant aux embouts (2) la pression nécessaire à exercer leur fonction de serrage. Thanks to the contraction, simultaneous or alternating, of the two hands, the levers (4) take a practically vertical position, parallel to the branches (figure 1) and thus force the stirrup (3) to descend lower, conferring on the end caps (2 ) the pressure necessary to exercise their tightening function.
On peut à présent lâcher le dispositif qui reste bloqué dans cette position. We can now let go of the device, which remains blocked in this position.
On voit immédiatement sur les dessins que l'espace situé entre l'étrier (3) et l'ensemble ayant fait l'objet du serrage permet de travailler normalement à cet endroit. Par exemple, cet espace autorise le passage d'une machine à poser les joints de mortier. It can be seen immediately in the drawings that the space between the stirrup (3) and the assembly which has been tightened makes it possible to work normally at this location. For example, this space allows the passage of a machine for laying mortar joints.
Le travail terminé, les leviers (4) sont repoussés vers l'intérieur, ce qui tire l'étrier (3) vers le haut et libère ainsi les branches (1) du dispositif qui s ouvre automatiquement. When the work is finished, the levers (4) are pushed inwards, which pulls the stirrup (3) upwards and thus frees the branches (1) from the device which opens automatically.
Aucun choc n'a été nécessaire, de simples pressions de la main ont suffi. Le dispositif n'inclut aucun mécanisme sensible à l'eau, au ciment, etc..., qui pourrait limiter son emploi sur un chantier. Pour peu que les matériaux utilisés soient suffisamment inaltérables et insensibles à l'eau, l'entretien en est extrêmement simple. No shock was necessary, simple pressure of the hand was enough. The device does not include any mechanism sensitive to water, cement, etc., which could limit its use on a site. As long as the materials used are sufficiently unalterable and insensitive to water, maintenance is extremely simple.
