Abstract

The invention relates to a device for assembling panels or other elements by screwing, using a screw that is arranged in the depth of the panel and which does not extend beyond the panel prior to screwing. The device does not require a piece that extends into the other panel as do existing devices, especially those termed "eccentric". The inventive device comprises four main pieces: two stationary pieces - the body (1), which is retained in the panel by a thread (2), and the guiding sleeve (6), which is provided with a short threaded part; and two mobile pieces - the socket (4) and the screw (5), which are driven by a screwdriver (10) that is introduced through a window (3). The socket and the screw are enclosed by the body and the sleeve. In this device, the screw (5) is guided forwards over the first part of its course by the thread of the guiding sleeve (6), until it meets the element in which it is to be inserted. The screw is then released for the final part of its course, in order to complete the tightening process, eventually being stopped on the rear of the guiding sleeve (6). The inventive device is especially suitable for assembling cupboards and book shelves. It is equally as suitable for pre-assembled furniture or furniture that is provided in assembly kits.

Description

La présente invention concerne un dispositif pour assembler des panneaux ou autres éléments par vissage avec une vis logée dans l'épaisseur du panneau et ne dépassant pas du panneau avant vissage. Le dispositif ne nécessite pas non plus de pièce dépassant dans l'autre panneau comme c'est actuellement le cas dans les dispositifs existants notamment ceux dits à excentrique . The present invention relates to a device for assembling panels or other elements by screwing with a screw housed in the thickness of the panel and not projecting from the panel before screwing. The device also does not require any part projecting into the other panel as is currently the case in existing devices, in particular those known as eccentric.

Cet avantage permettra des assemblages dans toutes les situations ou le recul manque pour l'insertion des pièces dépassantes par exemple pour le montage entre deux murs. This advantage will allow assemblies in all situations where there is no recoil for the insertion of protruding parts, for example for mounting between two walls.

Un autre avantage de ce dispositif, notamment pour des éléments livrés en kit ou pré-montés, est permettre l'insertion des vis au moment de la préparation des panneaux et de ne pas oir de pièces volantes supprimant ainsi les risques de perte ou d'erreur et facilitant la mise en eeuvre et le mode d'emploi. Another advantage of this device, in particular for elements delivered as a kit or pre-assembled, is to allow the insertion of screws during the preparation of the panels and not to have flying parts thus eliminating the risks of loss or error and facilitating the implementation and the manual.

Ce dispositif concerne aussi bien les vis à bois ou à aggloméré de bois que les boulons présentant des filetages divers. This device concerns both wood or chipboard screws as well as bolts with various threads.

Le dispositif est formé de quatre pièces principales : deux pièces fixes, le corps et le manchon et deux pièces mobiles, la douille et la vis, la cinquième pièce étant l'outil de vissage. I1 s'a < pt d'un dispositif simple et économique. La douille et la vis sont prisonnières du corps et manchon. The device is made up of four main parts: two fixed parts, the body and the sleeve and two moving parts, the socket and the screw, the fifth part being the screwing tool. It has a simple and economical device. The socket and the screw are captive of the body and sleeve.

La réalisation du corps pourra se faire en métal, en matière synthétique ou bien etre une forme creusée dans le matériau de la pièce à assembler. Les autres parties seront généralement métalliques. The body may be made of metal, of synthetic material or else be a hollowed out shape in the material of the part to be assembled. The other parts will generally be metallic.

Les dessins annexés illustrent l'invention : La FIG 1, en coupe longitudinale, montre la vis (5) en position rétractée et l'outil de vissage prêt à effectuer la mise en rotation de la douille. La FIG 2 montre la vis (5) ,.n position sortie et sa tête appuyée le manchon de guidage ( & ). Les FIG 3 et 4 montrent le corps (1). The accompanying drawings illustrate the invention: FIG 1, in longitudinal section, shows the screw (5) in the retracted position and the screwing tool ready to rotate the socket. FIG 2 shows the screw (5), .n out position and its head supported the guide sleeve (&). FIGS 3 and 4 show the body (1).

Le corps est en forme de cigare (1) avec un filetage extérieur (2) permettant le tenir au matériau dans lequel il est inséré et possède une ou plusieurs fenêtres (3) permettant le passage de l'outil. Dans les cas où l'on craint la poussière, la fenêtre peut être obturée une roue dentée faisant bouchon et présentant une empreinte permettant de l'actionner avec l'outil. La douille (4) est formée d'un logement creux, à six pans ou indifféremment d'une autre forme, allongé pour recevoir la tête de la vis ; elle est munie sur sa partie arrière d'un crantage formant une roue dentée et d'un axe pour son centrage qui aura également pour rôle de limiter la pénétration de l'outil de serrage. Pour certains besoins, on peut loger dans des cannelures pratiquées sur l'extérieur de la douille, des rouleaux facilitant la rotation. L'axe arrière de la douille (4) est cylindrique et peut se terminer par une forme sphérique. La vis (5) est caractérisée par une tête insérée dans le logement de la douille et un filetage interrompu près la tête permettant ainsi, par un affinement du corps de la vis, de la libérer en fin de course pour le serrage. Le manchon de guidage (6) est un cylindre creux inséré dans le corps et solidaire de ce dernier, comportant une partie filetée et facultativement logement (9) pour un ressort de rappel repoussant la vis vers l'arrière. The body is in the shape of a cigar (1) with an external thread (2) allowing it to hold to the material in which it is inserted and has one or more windows (3) allowing the passage of the tool. In cases where there is a fear of dust, the window can be closed off with a toothed wheel forming a stopper and having an imprint enabling it to be actuated with the tool. The sleeve (4) is formed by a hollow housing, with hexagon or indifferently of another shape, elongated to receive the head of the screw; it is provided on its rear part with a notch forming a toothed wheel and an axis for its centering which will also have the role of limiting the penetration of the tightening tool. For certain needs, one can accommodate in grooves made on the outside of the bushing, rollers facilitating rotation. The rear axis of the sleeve (4) is cylindrical and can end in a spherical shape. The screw (5) is characterized by a head inserted in the housing of the socket and an interrupted thread near the head thus allowing, by a refinement of the body of the screw, to release it at the end of travel for tightening. The guide sleeve (6) is a hollow cylinder inserted in and integral with the body, comprising a threaded part and optionally housing (9) for a return spring pushing the screw backwards.

Le manchon de guidage est solidarisé au corps du dispositif par tout moyen suivant la nature du matériau de construction du dispositif ; par exemple par collage ou par une goupille (8). The guide sleeve is secured to the body of the device by any means depending on the nature of the construction material of the device; for example by gluing or by a pin (8).

Dans ce dispositif la vis est conduite vers l'avant dans le début de sa course, par le filetage du manchon de guidage, à la rencontre de l'élément dans lequel elle va s'insérer, puis, afin d'effectuer le serrage, elle sera libérée dans la fin de sa course alors qu'elle se trouvera en butée l'arrière du manchon de guidage. In this device, the screw is driven forward at the start of its travel, by the thread of the guide sleeve, to meet the element in which it will be inserted, then, in order to carry out the tightening, it will be released at the end of its travel while it will be in abutment at the rear of the guide sleeve.

Dans ce dispositif le mouvement se transmet aisément à la douille, à travers une fenêtre du corps dispositif correspondant à un perçage discret du panneau, à l'aide d' outil manuel. un tournevis dont la forme cannelée est adaptée à la roue dentée de la douille ou d'un embout de vissage sur un outil mécanique ou électrique. Le perçage dans panneau sert de guide et de maintien à l'outil. Le dispositif ne nécessite à demeure qu'une roue dentée, celle de la douille, et l'engrenage est constitué par l'utilisation de l'outil. Le mouvement de rotation imprimé à la roue dentée est transfinis par la douille à la vis, tout en laissant la tête de la vis libre d'avancer ou de reculer. In this device the movement is easily transmitted to the socket, through a window of the device body corresponding to a discreet drilling of the panel, using a manual tool. a screwdriver whose fluted shape is adapted to the toothed wheel of the socket or of a screwdriver bit on a mechanical or electric tool. The hole in the panel serves as a guide and support for the tool. The device permanently requires only a toothed wheel, that of the socket, and the gear is formed by the use of the tool. The rotational movement imparted to the toothed wheel is transformed by the socket to the screw, while leaving the head of the screw free to move forward or backward.

L'entraînement se fait par un logement dans le corps de la douille ou indifféremment par des doigts prolongeant une roue dentée et formant le même mécanisme. The drive is done by a housing in the body of the socket or indifferently by fingers extending a toothed wheel and forming the same mechanism.

Suivant les besoins, le vissage s'effectuera directement dans le matériau ou dans insert solidaire du matériau. Depending on requirements, screwing will be carried out directly in the material or in an insert integral with the material.

Lors du dévissage, la vis vient rapidement à la rencontre du filetage du manchon qui lui permet de se rétracter totalement. When unscrewing, the screw quickly meets the thread of the sleeve which allows it to fully retract.

A titre d'exemple non limitatif, le dispositif aura des dimensions de 8 àlOmm diamètre et 6 à 8cin de long pour l'insertion dans des panneaux de 191nin d'épaisseur. By way of nonlimiting example, the device will have dimensions of 8 to 10 mm in diameter and 6 to 8 inches long for insertion into panels of 191 nm thickness.

Le dispositif selon l'invention est particulièrement adapté au montage de placards et bibliothèques de mur à mur et du sol au plafond en permettant la manipulation de grands panneaux sans besoin de recul pour placer les ferrures. Il sera aussi bien adapté au mobilier pré-monté ou livré en kit et l'on pourra, afin faciliter le montage par un centrage aisé des panneaux, créer un retrait du manchon de guidage correspondant à une légère saillie de la partie filetée sur l'autre pièce.The device according to the invention is particularly suitable for mounting closets and bookcases from wall to wall and from floor to ceiling by allowing the handling of large panels without the need to step back to place the fittings. It will also be well suited to pre-assembled furniture or delivered as a kit and, in order to facilitate assembly by easy centering of the panels, it will be possible to create a withdrawal of the guide sleeve corresponding to a slight projection of the threaded part on the other room.
