Abstract

The clamp has a fixed jaw (1) fixed to a support bracket (14). A threaded bolt (9) projects from the fixed jaw and passes through a tapped hole in the sliding jaw (2). The sliding jaw (2) is supported in a channel section guide (5) with an end cap (11) which supports the free end of the bolt (9). The crest diameter of the thread (12) in the sliding jaw is larger than the crest diameter of the thread of the bolt. This enables the jaw to slide over the bolt when the force of the locking spring (6) is overcome by pressing on the serrated thumb grip (12).

Description

L'invention concerne un dispositif de serrage comportant au moins un mors à position réglable dont le déplacement et le serrage sont commandés par une broche filetée associée à un filetage intérieur du mors, un déplacement rapide du mors pouvant être effectué lorsque la liaison entre la broche filetée et le filetage intérieur du mors est interrompue contre la résistance d'un ressort, le mors pouvant alors être déplacé à la main le long d'une glissière
Un dispositif de serrage de ce type est déjà connu sous forme d'un étau à vis à serrage rapide vendu dans le commerce.Cet étau connu est toutefois d'une construction onéreuse, le filetage du mors mobile étant disposé dans un élément de construction distinct monté dans le mors avec possibilité de déplacement contre l'action d'un ressort, élément pour lequel des butées appropriées doivent être prévues et qui rend nécessaire une opération supplémentaire lors du montage du dispositif de serrage.
The invention relates to a clamping device comprising at least one jaw with adjustable position, the displacement and clamping of which are controlled by a threaded spindle associated with an internal thread of the jaw, a rapid displacement of the jaw being able to be effected when the connection between the spindle threaded and the internal thread of the jaw is interrupted against the resistance of a spring, the jaw can then be moved by hand along a slide
A clamping device of this type is already known in the form of a commercially available quick-clamping screw vice, but this known vice is of an expensive construction, the threading of the movable jaw being arranged in a separate construction element. mounted in the jaw with the possibility of displacement against the action of a spring, an element for which appropriate stops must be provided and which necessitates an additional operation when mounting the clamping device.

L'invention a pour objet de donner à un dispositif de serrage du type décrit plus haut une conformation telle que sa construction soit simple et réalisable à partir du plus petit nombre possible de pièces individuelles, sans pour autant que la fiabilité du dispositif soit compromise. Dans le même temps, l'utilisation du dispositif doit etre simplifiée au maximum. The object of the invention is to give a clamping device of the type described above a conformation such that its construction is simple and achievable from the smallest possible number of individual parts, without however compromising the reliability of the device. At the same time, the use of the device should be simplified as much as possible.

Les dispositions prévues par 18invention résolvent ce problème par le fait que le diamètre de passage du perçage du mors recevant le filetage inié- rieur est supérieur au diamètre extérieur de la broche filetée, que les axes eenvcraux longitudinaux du per çage et de la broche filetée (considerée lorsque les pièces sont montées) ne sont pas parallèles et que le mors est monté sur la broche filetée avec possibilité 'de pivotement par rapport à celle-ci contre la résistance d'un ressort. The provisions provided by 18invention solve this problem by the fact that the passage diameter of the bore of the jaw receiving the inner thread is greater than the outside diameter of the threaded spindle, than the longitudinal axes of the bore and of the threaded spindle ( considered when the parts are mounted) are not parallel and the jaw is mounted on the threaded spindle with the possibility of pivoting relative thereto against the resistance of a spring.

Une construction particulièrement simple et permettant de plus un montage sans problème est obtenue lorsque le mors est soumis à l'action d'un ressort prenant appui sur la glissière. A particularly simple construction and moreover allowing a problem-free assembly is obtained when the jaw is subjected to the action of a spring bearing on the slide.

Un dispositif de serrage selon l'invention trouve une application particulièrement avantageuse en tant que partie d'un support de bicyclette pour voiture de tourisme. A clamping device according to the invention finds a particularly advantageous application as part of a bicycle support for a passenger car.

Dans ce qui suit, l'invention est expliquée plus en détail sur un exemple d'exécution illustré par des Figures. Celles-ci représentent
Figure 1, une vue de dessus du dispositif de serrage conforme à l'invention
Figure 2, une coupe selon la ligne II-II de la Figure 1.
In the following, the invention is explained in more detail on an exemplary embodiment illustrated by Figures. These represent
Figure 1, a top view of the clamping device according to the invention
Figure 2, a section along line II-II of Figure 1.

Le dispositif de serrage conforme à l'invention présente un mors fixe 1 et un mors mobile 2 montés tous les deux dans un tube de section carrée 3 présentant sur sa face supérieure une rainure de guidage 4 dont les bords latéraux 5 servent au guidage du mors mobile 2 et à l'appui d'un ressort 6 agissant sur ce mors mobile. Le mors fixe 1 est fixé par une vis 7 à une plaque terminale 8 fermant sur un c6té le tube à section carrée 3. La plaque terminale 8 sert également au montage tournant d'une broche filetée 9 dont l'autre extrémité, conformée en tête quatre pans 10, est montée à rotation dans une douille 11. The clamping device according to the invention has a fixed jaw 1 and a movable jaw 2 both mounted in a tube of square section 3 having on its upper face a guide groove 4 whose lateral edges 5 serve to guide the jaw mobile 2 and in support of a spring 6 acting on this mobile jaw. The fixed jaw 1 is fixed by a screw 7 to an end plate 8 closing on a side the square section tube 3. The end plate 8 is also used for the rotary mounting of a threaded pin 9 whose other end, shaped at the head hexagon 10, is rotatably mounted in a socket 11.

Dans la partie formant la base de la mâ- choire mobile 2, est prévu un perçage 12 présentant un filetage intérieur, perçage dont le diamètre Se passage en inférieur au diamètre extérieur de la broche filetée 9 et dont l'axe central longitudinal n'est pas parallèle à l'axe central longitudinal de la broche filetée 9. In the part forming the base of the movable jaw 2, there is provided a bore 12 having an internal thread, a bore whose diameter passes below the outside diameter of the threaded pin 9 and whose longitudinal central axis is not not parallel to the longitudinal central axis of the threaded spindle 9.

En position de montage, le filetage du mors 2 et celui de la broche filetée 9 engrènent par conséquent partiellement (sur la Figure 2, en bas et à gauche et en haut et à droite), de sorte qu'un réglage de la position du mors 2 par un outil manoeuvrant le quatre pans 10 est possible.In the mounting position, the thread of the jaw 2 and that of the threaded spindle 9 therefore partially mesh (in FIG. 2, at the bottom and left and at the top and right), so that an adjustment of the position of the jaw 2 by a tool operating the hexagon 10 is possible.

Si toutefois, le mors 2 doit être déplacé à la main sur une distance plus importante, il suffit d'exercer une pression sur la surface de prise 12 pour interrompre la liaison par filetages. La pression cessant de s'exercer sur la surface de prise 12, le mors 2 se trouve automatiquement ramené par l'action du ressort 6 dans la position représentée sur les Figures. If, however, the jaw 2 must be moved by hand over a greater distance, it suffices to exert pressure on the gripping surface 12 to interrupt the connection by threads. The pressure ceasing to be exerted on the gripping surface 12, the jaw 2 is automatically brought back by the action of the spring 6 to the position shown in the Figures.

L'exemple d'exécution représenté constitue une partie d'un support de bicyclette adaptable sur un véhicule. Pour fixation sur le support, le dispositif de serrage est fixé par un rivetage 13 sur une patte en
U(14) fixée à son tour (de façon non représentée) au support.
The exemplary embodiment shown constitutes part of a bicycle support adaptable to a vehicle. For fixing on the support, the clamping device is fixed by a riveting 13 on a tab in
U (14) in turn fixed (not shown) to the support.
