Description

Outil de serrage. Lobjet de la presente invention est un outil de serrage. Il est caracterise par un manche dont au moins une extremit6 se ter- mine par un disque, par au moins une tete de cle presentant une mächoire et un disque correspondant au disque du manche, et par un dispositif d'engagement et de fixation de ces disques dans plusieurs positions angu- laires. Clamping tool. The object of the present invention is a clamping tool. It is characterized by a handle, at least one end of which ends in a disk, by at least one key head having a jaw and a disk corresponding to the disk of the handle, and by a device for engaging and fixing these discs in several angular positions.

Le dessin ei-annexe represente, ä titre d'exemple, une forme d'execution de 1'objet de 1'invention. The appended drawing represents, by way of example, one form of execution of the object of the invention.

La fig. 1 est une vue en elevation et la fig. 2 une vue en plan du manche de celle-ci. La fig. 3 est une vue en plan et une coupe d'un jeu de deux tetes de c1es. fig. 1 is an elevational view and FIG. 2 a plan view of the handle thereof. fig. 3 is a plan view and a section of a set of two c1es heads.

La forme d'execution representee com- prend un manche plat 1 en acier coule pre- sentant, ä ses extremites, des disques 2 et 3 de grandeurs differentes. Environ aux deux Hers du rayon de ces disques sont disposees perpendiculairement cinq goupilles 4, respec- tivement 4', equidistantes, venues de fonde- rie avee 1e manche. Au centre de ces disques est fixee une goupille elastique fendue 5, res- pectivement 5'. The embodiment represented comprises a flat handle 1 of cast steel having, at its ends, discs 2 and 3 of different sizes. Approximately two Hers of the radius of these discs are arranged perpendicularly five pins 4, respectively 4 ', equidistant, coming from the foundry with the first handle. At the center of these discs is fixed a split spring pin 5, respectively 5'.

Chaque Ute de c16, 6 ou 7 par exemple, presente une mächoire ordinaire 8; ou'9 et un disque 2' ou 3'. Ce disque presente un trou central correspondant ä la goupille kastique fendue 5 ou 5', cinq trous correspondant aux cinq goupilles 4 et 4', et cinq trous addi- tionnels intermediaires. Un jeu de tetes de cle Sera de prference de deux jeux partiels s'adaptant respectivement aux extremites 2 et 3 du manche. Each Ute of c16, 6 or 7 for example, presents an ordinary jaw 8; or '9 and a 2' or 3' disc. This disc has a central hole corresponding to the split kastic pin 5 or 5', five holes corresponding to the five pins 4 and 4', and five intermediate additional holes. A set of key heads will preferably be two partial sets fitting respectively at ends 2 and 3 of the handle.

Le mode d'utilisation de cet outil est 1e suivant: 0n choisit premierement parmi les deux jeux partiels une tete de cle dont la mächoire corresponde ä 1'ecrou ä serrer ou ä desserrer, puis an applique 1e disque de cette tete sur 1'extremite correspondante du manche dans 1'orientation la plus commode. Le dispositif de fixation avec goupille fendue permet 1e changement rapide d'orientation du manche, 6e qui est particulierement pratique pour les ecrous d'un acces difficile. Les avantages de cet outil sont donc 1e poids et 1'encombrement reduits par 1e fait qu'il suffit dun Beul manche par jeu de tetes de cle, et la possibilite d'orienter 1e manche de la c16, par rapport ä la mächoire, dans sept positions utiles differentes. The method of use of this tool is as follows: one first chooses from among the two partial sets a spanner head whose jaw corresponds to the nut to be tightened or loosened, then one applies the disk of this head to the end handle in the most convenient orientation. The cotter pin attachment device allows for quick change of handle orientation, which is especially handy for hard-to-reach nuts. The advantages of this tool are therefore the reduced weight and size due to the fact that only one handle is required per set of wrench heads, and the possibility of orienting the handle of the c16, with respect to the jaw, in seven different useful positions.

En Variante, an pourrait prevoir un dis- positif d'engagement des disques 1'un dans 1'autre au moyen dune denture radiale que presenteraient ces disques sur l'une de leurs faces. Le dispositif de fixation pourrait, en outre, consister en un boulon central avee eorou qui serreraient les deux disques 1'un sur 1'autre. As a variant, a device could be provided for engaging the discs with each other by means of radial toothing which these discs would present on one of their faces. The fixing device could, moreover, consist of a central bolt with oro which would clamp the two discs 1'un on 1'autre.

Claims

CLAIM Tightening tool, characterized by a handle of which at least one end ends in a disk, by at least one key head having a jaw and a disk corresponding to the disk of the handle, and by an engagement device and fixing these discs in several angular positions. SUB-CLAIMS 1. A clamping tool according to claim, characterized in that the engagement and fixing device consists of a split central elastic pin and several pins angularly equidistant from one of the discs and engaging corresponding holes of the other disc. ?. Clamping tool according to claim, characterized in that the first handle ends in a disc a. its two extremities and by a game of key head sleeps the discs engage on one or the other of the extremities of the handle. 3. Tightening tool according to claim, characterized in that the first engagement and fixing device is constituted by radial toothing of the discs and by a central bolt with nut.
