Description
Jeu de tampons pour la fixation de vis dans les murs La présente invention a pour objet un jeu de tampons pour la fixation de vis dans des murs. Ce jeu est caractérisé par une gouttière en matière plas tique synthétique de forme de-mi-cylindrique et des tinée à recevoir une mèche servant à percer les trous dans les murs et par deux séries de tampons égale ment en matière plastique synthétique venus <RTI
ID="0001.0014"> d'une seule pièce moulée avec la gouttière et rattachés à celle-ci par une mince languette permettant d'ar racher les tampons de la gouttière.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention.
La fig. 1 montre en élévation une portion du jeu de tampons dans lequel deux tampons ont été enle- vés.
La fig. 2 est une vue en plan correspondante. La fig. 3 montre en plan, à plus grande échelle, un tampon isolé.
La fig. 4 montre ce même tampon en élévation. La fig. 5 en montre une coupe transversale selon la ligne V-V de la fig. 4.
La fig. 6 montre un tampon en coupe longitudi nale selon la ligne VI-VI de la fig. 4.
La fig. 7 montre, en bout, la gouttière avec un tampon.
Le jeu de tampons représenté comprend une gouttière demi-cylindrique 1 et deux séries de tam pons 2 attachés par une de leurs extrémités aux 1è- vres de la gouttière 1 au moyen de petites languet tes 9.
La gouttière et les tampons sont en matière plas tique synthétique et sont venus -d'une seule pièce moulée. Les languettes 9 sont suffisamment minces pour que les tampons puissent être séparés de la gouttière par arrachement.
La gouttière présente, faisant saillie sur ses lè vres, deux à trois paires de pitons 3. Cette gouttière est prévue pour servir de logement à la mèche 7 né cessaire pour percer dans les murs les trous destinés à recevoir les tampons. Son diamètre est donc égal à celui de cette mèche. Les pitons 3 servent à tenir la mèche en place dans la gouttière (voir fig. 7).
Chaque tampon est constitué par un corps tubu laire 2, légèrement conique et fermé à son extré mité inférieure. Une fente mince et profonde 5 s'étend du bord supérieur de l'orifice du tampon, le long du corps de celui-ci, traverse la pointe et re vient jusqu'au bord de l'orifice,
en un point diamé tralement opposé à celui de départ. Cette fente laisse subsister, antre le fond et la paroi de la cavité 4 du corps 2, une mince membrane 5' qui, en se cassant, permet à la vis introduite dans le tampon de dilater ce dernier afin qu'il vienne en prise avec la paroi du trou percé dans le mur.
Set of buffers for fixing screws in walls The present invention relates to a set of buffers for fixing screws in walls. This set is characterized by a gutter in synthetic plastic material of semi-cylindrical shape and tines to receive a drill bit used to drill holes in the walls and by two series of plugs also in synthetic plastic material come <RTI
ID = "0001.0014"> in one single piece molded with the gutter and attached to it by a thin tab allowing the gutter pads to be scraped off.
The appended drawing represents, by way of example, an embodiment of the object of the invention.
Fig. 1 shows in elevation a portion of the pad set from which two pads have been removed.
Fig. 2 is a corresponding plan view. Fig. 3 shows a plan, on a larger scale, of an isolated buffer.
Fig. 4 shows this same buffer in elevation. Fig. 5 shows a cross section along the line V-V of FIG. 4.
Fig. 6 shows a plug in longitudinal section along the line VI-VI of FIG. 4.
Fig. 7 shows, at the end, the gutter with a plug.
The set of pads shown comprises a semi-cylindrical gutter 1 and two sets of pads 2 attached by one of their ends to the lips of the gutter 1 by means of small tabs 9.
The gutter and the pads are made of synthetic plastic and are made from a single molded piece. The tabs 9 are thin enough so that the pads can be pulled out from the gutter.
The gutter has, projecting from its lips, two to three pairs of eyebolts 3. This gutter is designed to serve as a housing for the wick 7 necessary for drilling the holes in the walls for receiving the buffers. Its diameter is therefore equal to that of this wick. The eyebolts 3 are used to hold the bit in place in the gutter (see fig. 7).
Each plug consists of a tubular body 2, slightly conical and closed at its lower end. A thin and deep slit 5 extends from the upper edge of the orifice of the tampon, along the body of the latter, passes through the point and comes back to the edge of the orifice,
at a point diametrically opposite to the starting point. This slot leaves, between the bottom and the wall of the cavity 4 of the body 2, a thin membrane 5 'which, by breaking, allows the screw introduced into the tampon to expand the latter so that it comes into engagement with the wall of the hole drilled in the wall.
