Abstract

The solid cylindrical bar anchor (1) has a countersunk head (2) at one end and has cylindrical sections (5) over part of its length. The axis of the sections form a broken line between the. Each section has a projecting anchoring notch (4) and the section ends extend beyond both sides of the nominal bar diameter. The inscribed circle dia. of the cylindrical sections is the same as the dia. of the anchoring bores (5). Only the anchoring notches exceed this dia. A cylindrical ferrule (6) at the anchor free end, of the same section as the bar, centres the anchor in the bores.

Description

La présente invention concerne le domaine de la fixation par ancrage d'éléments divers sur des murs ou à des plafonds, et a pour objet un élément de fixation par ancrage. The present invention relates to the field of fixing by anchoring various elements on walls or ceilings, and relates to an element of fixing by anchoring.

Actuellement, la fixation d'éléments de revêtement intérieurs ou extérieurs et/ou d'isolation sur des murs ou à des plafonds est généralement réalisée au moyen de vis coopérant avec des chevilles métalliques ou en matière synthétique préalablement fixées dans des perçages
Ces différents dispositifs de fixation par ancrage connus permettent généralement un bon maintien des éléments à fixer aux murs et aux plafonds. Cependant, leur mise en oeuvre est relativement lente, même en cas de clouage des vis, du fait qu'une mise en place préalable des chevilles est toujours nécessaire.Currently, the fixing of interior or exterior cladding elements and / or insulation on walls or ceilings is generally carried out by means of screws cooperating with metal or plastic pegs previously fixed in holes.
These various known anchoring fastening devices generally allow good retention of the elements to be fixed to walls and ceilings. However, their implementation is relatively slow, even in the case of nailing the screws, because a prior installation of the dowels is always necessary.

La présente invention a pour but de pallier ces inconvénients. The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un élément de fixation par ancrage caractérisé en ce qu'il est constitué par une barre cylindrique pleine, dont une extrémité est munie d'une tête fraisée, ou autre, et qui présente, du côté opposé à la tête, sur une partie de sa longueur, des sections cylindri ques.disposées entre elles suivant un axe de ligne brisée et pourvues chacune d'au moins un cran d'accrochage en saillie, les extrémités de chaque section dépassant de part et d'autre le diamètre nominal de la barre cylindrique, et s'inscrivant sensiblement dans un cercle dont le diamètre correspond au diamètre du perçage destiné à l'ancrage, seuls les crans d'accrochage dépassant ce diamètre. It has, in fact, for its object an anchoring fastening element characterized in that it consists of a solid cylindrical bar, one end of which is provided with a countersunk head, or the like, and which has, on the side opposite to the head, over part of its length, of cylindrical sections arranged between them along a broken line axis and each provided with at least one projecting hooking notch, the ends of each section projecting from both sides other the nominal diameter of the cylindrical bar, and substantially forming part of a circle whose diameter corresponds to the diameter of the bore intended for anchoring, only the catch notches exceeding this diameter.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dont la figure unique est une vue en élévation d'un élément conforme à l'invention. The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, the single figure of which is a view in elevation of an element according to the invention.

L'élément de fixation par ancrage, représenté au dessin annexé, est constitué par une barre cylindrique pleine 1 dont une extrémité est munie d'une tête fraisée 2 ou autre. Du côté opposé à la tête 2, la barre 1 présente, sur une partie de sa longueur, par exemple sur la moitié de celle-ci, des sections cylindriques 3, qui sont disposées entre elles suivant un axe de ligne brisée, et qui sont pourvues chacune d'au moins un cran d'accrochage 4 en saillie. Les extrémités de ces sections 3 dépassent de part et d'autre le diamètre nominal de la barre 1, qui est représenté en traits mixtes fins dans le dessin, et s'inscrivent dans un cercle dont le diamètre correspond au diamètre du perçage 5 destiné à l'ancrage. Les crans d'accrochage 4 dépassent ce diamètre et pénètrent ainsi dans les parois du perçage 5 en réalisant l'ancrage de l'élément conforme à l'invention. The anchoring fastening element, shown in the accompanying drawing, consists of a solid cylindrical bar 1, one end of which is provided with a countersunk head 2 or the like. On the side opposite the head 2, the bar 1 has, over a part of its length, for example over half of it, cylindrical sections 3, which are arranged between them along a broken line axis, and which are each provided with at least one hooking notch 4 projecting. The ends of these sections 3 exceed on both sides the nominal diameter of the bar 1, which is shown in thin broken lines in the drawing, and are inscribed in a circle whose diameter corresponds to the diameter of the hole 5 intended for anchoring. The hooking notches 4 exceed this diameter and thus penetrate into the walls of the bore 5 by anchoring the element according to the invention.

La partie inférieure de la barre 1 présentant les sections cylindriques 3 et les crans 4 est avantageusement réalisée par déformation à la presse. The lower part of the bar 1 having the cylindrical sections 3 and the notches 4 is advantageously produced by deformation with the press.

Conformément à une caractéristique de l'invention, pour réaliser un centrage correct de l'élément dans le perçage 5, son extrémité opposée à la tête 2 est avantageusement sous forme d'un embout cylindrique 6 de même section que la barre 1, et coaxial à cette dernière. According to a characteristic of the invention, to achieve correct centering of the element in the bore 5, its end opposite to the head 2 is advantageously in the form of a cylindrical end piece 6 of the same section as the bar 1, and coaxial to the latter.

Ainsi, lors de la mise en place d'éléments de revêtement et/ou d'isolation, l'élément conforme à l'invention est centré au moyen de son embout 6 sur le perçage 5 et est enfoncé dans ce dernier par clouage. Lors de cette opération, les sections cylindriques 3 se déforment élastiquement favorisant l'enfoncement, et à la fin de cette opération les crans d'accrochage 4 mordent dans la paroi du perçage 5 où ils retiennent fortement l'élément de fixation. L'élément conforme à l'invention permet une fixation définitive par ancrage efficace et rapide de tous dispositifs, avec une possibilité de rattrapage d'un jeu éventuel par simple enfoncement supplémentaire de l'élément. Thus, during the installation of covering and / or insulation elements, the element according to the invention is centered by means of its end piece 6 on the bore 5 and is pressed into the latter by nailing. During this operation, the cylindrical sections 3 deform elastically favoring the sinking, and at the end of this operation the hooking notches 4 bite into the wall of the bore 5 where they strongly retain the fixing element. The element according to the invention allows final fixing by effective and rapid anchoring of all devices, with the possibility of taking up any play by simply pressing the element further.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, by substitution of technical equivalents, without departing from the scope of protection of the invention.
