Abstract

The concrete vibrating accessory includes a tube (9) which is fitted to the spinning output shaft of an electric drill (8) by a threaded end piece. This tube lies inside an outer larger tube (1) which is closed at one end by a plate having an internal pivot (2). The open end of this larger diameter tube is attached to the body of the electric drill and retained by a circular clamp which is retained with a nut and bolt (4,5,6). The rotation of the inner tube by the electric drill within the outer tube causes vibration of the outer tube as a result of their differences in diameter and may be used in order to mix and compact concrete to improve its compactness and strength.

Description

VIBREUR DE BETON ACCESSOIRE DE PERCEUSE ELECTRIQUE PORTATIVE
La présente invention concerne un ensemble mécanique ou appareil adaptable en tant qu'accessoire sur de nombreuses perceuses électriques portatives permettant de procéder à ia vibration de produits aqueux ou pâteux et principalement du béton lors de sa mise en oeuvre.ACCESSORY CONCRETE VIBRATOR OF PORTABLE ELECTRIC DRILL
The present invention relates to a mechanical assembly or device adaptable as an accessory to many portable electric drills for carrying out ia vibration of aqueous or pasty products and mainly concrete during its implementation.

HISTORIQUE
Dans les domaines du bâtiment et du génie civil, la vibration des bétons lors de leur mise en oeuvre est nécessaire afin de maximiser leur compacité et leur résistance. De nombreux procedés ont été utilises à cet effet tels que tables vibrantes, ultrasons, air comprimé, électromagnétisme, moteurs électriques ou autres. La tendance actuelle est axée sur la recherche de vibreurs efficaces, peu encombrants, légers, de maniement facile et de moindre coût. Le classique compresseur d'air alimentant avec un tuyau souple une aiguille vibrante, reste l'image d'un outil lourd, encombrant, bruyant, peu maniable et coûteux, souvent hors de portée du bricoleur et du petit artisan.HISTORICAL
In the fields of building and civil engineering, the vibration of concretes during their implementation is necessary in order to maximize their compactness and their resistance. Many methods have been used for this purpose such as vibrating tables, ultrasound, compressed air, electromagnetism, electric motors or others. The current trend is focused on the search for effective vibrators, compact, light, easy to use and inexpensive. The classic air compressor supplying a vibrating needle with a flexible hose, remains the image of a heavy, bulky, noisy, unwieldy and expensive tool, often out of reach of the handyman and the small craftsman.

Telles sont les bases de reflexion qui nous ont amené à concevoir un nouveau type de vibreur tel que ci-après décrit.These are the basics of reflection which led us to design a new type of vibrator as described below.

DESCRIPTION TECHNIQUE
L'appareil consiste en la combinaison de
A - Un gros tube (1) obturé a l'une de ses extrémités par une fermeture comportant un pivot intérieur (2), l'autre extrémité restant ouverte est fendue d'un côté sur une longueur de plusieurs centimètres (3) et équipée de deux oreilles percées 4), au travers desquelles un boulon (5j avec écrou (6) permettent après emboîtement sur le col de broche porte-accessoires (7) en général cylindrique, ou de toute autre configuration d'une perceuse électrique portative (8), de le fixer solidement.TECHNICAL DESCRIPTION
The device consists of the combination of
A - A large tube (1) closed at one of its ends by a closure comprising an internal pivot (2), the other end remaining open is split on one side over a length of several centimeters (3) and equipped two pierced ears 4), through which a bolt (5j with nut (6) allows after fitting on the collar of the accessory holder spindle (7) generally cylindrical, or of any other configuration of a portable electric drill (8 ), to fix it securely.

B - Un tube intérieur < 9) taraudé à l'une de ses extrémités afin de le fixer sur la broche (10) tournante de la perceuse (8). B - An inner tube <9) threaded at one of its ends in order to fix it on the rotating spindle (10) of the drill (8).

FONCTIONNEMENT
Après fixation du tube (9r sur la broche (l0) de la perceuse (8), et du tube (1) sur le col de broche porte-accessoires 17) de la même perceuse (8), la mise en marche de ladite perceuse & ) provoque la rotation du tube (9) à l'intérieur du tube (1). . La différence de diamètre entre l'intérieur du tube (9) et le pivot de la pièce de fermeture i2) provoque la vibration du tube (9 < et du tube (l). OPERATION
After fixing the tube (9r on the spindle (10) of the drill (8), and the tube (1) on the neck of the accessory holder spindle 17) of the same drill (8), the starting of said drill &) causes the tube (9) to rotate inside the tube (1). . The difference in diameter between the inside of the tube (9) and the pivot of the closure part i2) causes the tube (9 <and the tube (l) to vibrate.

AVANTAGE
L'ensemble perceuse + vibreur est de faible poids, parfaitement maniable, branchable sur une prlse coronaire de courant domestique, de faible coût, utilisable et à la portée aussi bien du bricoleur que de la grosse entreprise. ADVANTAGE
The drill + vibrator assembly is light in weight, perfectly handy, connectable to a coronary prlse of household current, low cost, usable and within the reach of both the handyman and the big company.
