Abstract

The tool bit for predrilling and screwing of a screw fastener has a screw drive ferrule (2) with a tip extension (1) fixed or movable with respect to the screws used. The drill extension can be fixed and an integral part of the ferrule, or can be slidable along the center axis of the ferrule encased in a support.

Description

La présente invention concerne un dispositif permettant d'effectuer aussiThe present invention relates to a device for performing also

bien l'indispensable préperçage que le vissage d'une vis, dispositif pouvant s'adapter sur tous  the essential pre-drilling as well as the screwing of a screw, a device that can be adapted to all

types de visseuse ou support d'embout de vissage.  types of screwdriver or screwdriver bit holder.

Traditionnellement, pour réaliser les deux opérations précitées, il est utilisé deux machines ou outils bien distincts: une perceuse munie d'une mèche ou une pointe à avant-trou pour le préperçage, et une visseuse ou un tournevis pour le vissage, ce qui nécessite un double  Traditionally, to carry out the two aforementioned operations, two very distinct machines or tools are used: a drill with a drill bit or a point with a pilot hole for pre-drilling, and a screwdriver or screwdriver for screwing, which requires a double

investissement et occasionne une importante perte de temps.  investment and causes a significant loss of time.

Le dispositif selon l'invention permet de remédier à ces inconvénients. Il comporte en effet un embout de vissage prolongé en son extrémité libre d'une mèche fixe ou mobile  The device according to the invention overcomes these drawbacks. It indeed has a screwdriver end extended at its free end with a fixed or movable drill bit

selon les vis utilisées.depending on the screws used.

Deux modes de réalisation du dispositif sont illustrés dans les dessins annexés: La figure l représente le dispositif de l'invention avec  Two embodiments of the device are illustrated in the accompanying drawings: FIG. 1 represents the device of the invention with

une mèche fixe.a fixed wick.

Les figures 2 en coupe, 3 en coupe et 4 représentent le 20 dispositif de l'invention avec une mèche mobile.  Figures 2 in section, 3 in section and 4 show the device of the invention with a movable wick.

En référence à la figure 1, le dispositif comporte un embout de vissage (2) prolongé en son extrémité libre d'une mèche (1) de diamètre 2 mm et de longueur 4 mm. La mèche (1), qui fait partie intégrante de l'embout (2) , peut 25 être fixée à l'embout (2) par soudure, ou collage dans un trou ou une entaille exécutés dans l'extrémité libre de l'embout (2). L'embout (2) et la mèche (1) peuvent aussi  Referring to Figure 1, the device comprises a screwdriver bit (2) extended at its free end by a drill bit (1) with a diameter of 2 mm and a length of 4 mm. The drill bit (1), which is an integral part of the end piece (2), can be fixed to the end piece (2) by welding, or gluing in a hole or a cut made in the free end of the end piece. (2). The nozzle (2) and the drill bit (1) can also

être réalisés en une seule et même pièce.  be made in one piece.

Le dispositif est particulièrement destiné à la mise 30 en place de certaines vis existant sur le marché, puisqu' elles présentent en leur centre une cavité servant à recevoir un cache-vis, cavité pouvant par conséquent recevoir la mèche (1) située sur l'embout (2) lors du vissage qui s'en trouve facilité grâce au maintien de la vis par la mèche (1). 35 En référence aux figures 2 en coupe, 3 en coupe et 4, le dispositif comporte un support (3) en forme de tube dont l'intérieur est hexagonal sur toute sa longueur et la section -2  The device is particularly intended for the installation of certain screws existing on the market, since they have in their center a cavity serving to receive a screw cover, cavity being able therefore to receive the drill bit (1) located on the tip (2) when screwing which is facilitated by holding the screw by the drill bit (1). 35 With reference to FIGS. 2 in section, 3 in section and 4, the device comprises a support (3) in the form of a tube whose interior is hexagonal over its entire length and the section -2

appropriée pour recevoir l'embout de vissage (4).  suitable for receiving the screwdriver bit (4).

Le support (3) comporte une entaille (6) d'une largeur pouvant être, selon la réalisation, de 2,2 mm ou 3,2 mm et d'une longueur variable selon les besoins de l'utilisateur, entaille (6) se prolongeant perpendiculairement à ses extrémités pour servir de butée et de blocage au bouton-poussoir (9). Le support (3) reçoit en son centre deux pièces fixes (8 et 10) hexagonales et une mèche mobile (5). La pièce fixe aimantée (10) sert de butée à l'embout (4) et est percée en 10 son centre d'un trou de diamètre 2,2 mm pour permettre le passage de la mèche (5). La pièce fixe (8) sort du support (3) d'environ 15 mm afin que ce dernier soit relié à une visseuse ou à tout autre support d'embout de vissage. La mèche mobile (5) d'un diamètre de 2 mm et d'une longueur variable selon les besoins de l'utilisateur, comporte une partie cylindrique de plus gros diamètre correspondant à la dimension intérieure du support (3), avec le jeu nécessaire pour que la mèche coulisse aisément. Le bouton- poussoir (9), situé sur le support (3), sert à maintenir la mèche (5) en position "sortie" par rapport 20 à l'embout (Fig.2 en coupe) ou "rentrée" dans l'embout (Fig.3 en coupe et 4). Il est arrondi sur son dessus de façon ergonomique pour une meilleure préhension et est de couleur vive  The support (3) comprises a notch (6) of a width which may be, depending on the embodiment, of 2.2 mm or 3.2 mm and of a variable length according to the needs of the user, notch (6) extending perpendicularly to its ends to serve as a stop and blocking for the push button (9). The support (3) receives in its center two fixed pieces (8 and 10) hexagonal and a movable wick (5). The magnetized fixed part (10) serves as a stop for the end piece (4) and is pierced at its center with a hole with a diameter of 2.2 mm to allow the passage of the drill bit (5). The fixed part (8) comes out of the support (3) of about 15 mm so that the latter is connected to a screwdriver or any other support for a screwdriver bit. The movable wick (5) with a diameter of 2 mm and a variable length according to the needs of the user, comprises a cylindrical part of larger diameter corresponding to the internal dimension of the support (3), with the necessary clearance so that the wick slides easily. The push button (9), located on the support (3), serves to maintain the wick (5) in the "out" position relative to the end piece (Fig.2 in section) or "retracted" into the end piece (Fig. 3 in section and 4). It is ergonomically rounded on its top for better grip and is brightly colored

pour un repérage facile. Il est fixé à la partie cylindrique de plus gros diamètre de la mèche (5) à l'aide d'une vis (11) 25 d'un diamètre de 2 ou 3 mm selon la largeur de l'entaille (6).  for easy identification. It is fixed to the larger diameter cylindrical part of the drill bit (5) using a screw (11) 25 with a diameter of 2 or 3 mm depending on the width of the notch (6).

Cette vis (11) coulisse dans l'entaille (6) et possède un filetage interrompu pour servir de butée et créer le jeu  This screw (11) slides in the notch (6) and has an interrupted thread to serve as a stop and create the game

nécessaire au bon fonctionnement dudit bouton-poussoir (9).  necessary for the proper functioning of said push button (9).

L'embout de vissage (4) percé en son milieu d'un trou de 30 diamètre 2,2 mm pour permettre le passage de la mèche (5) vient s'emboiter dans le support (3). L'embout de vissage (4) pourra  The screwdriver bit (4) drilled in the middle of a hole with a diameter of 2.2 mm to allow the passage of the drill bit (5) fits into the support (3). The screwdriver bit (4) can
