Description
Charnière pour mètre pliant. La présente invention a pour objet une charnière pour mètre pliant.
Le dessin annexé donne, à titre d'exem ple, deux formes d'exécution de l'objet de la présente invention.
La fig. 1 est une vue en plan d'une pre mière forme d'exécution; La fig. 2 en est une vue en coupe suivant la ligne A-B de la fig. 1; La fig. 3 est une vue en plan d'une se- seconde forme d'exécution; La fig. 4 en est une vue en coupe suivant la ligne C-D de la fig. 3.
Cette charnière comporte deux plaques 1 et l', fixées chacune à l'extrémité des élé ments 2 de mètre pliant qu'ils doivent réunir; à cet effet, les bords des plaquettes 1 sont rabattus sur les faces latérales inclinées de l'élément 2 et les aspérités 3 prévues dans le fond de la plaquette 1 sont enfoncées dans la face de l'élément 2.
Les plaquettes 1 et l' sont réunies par un axe 4 qui les traverse et autour duquel elles peuvent pivoter, dans le but de permettre de plier ou déplier le mètre. Cet axe 4 est muni d'une tête 5 sous laquelle prend appui un ressort à lame 6 dont les extrémités reposent sur la plaquette 1. L'axe 4 est maintenu au moyen d'une rondelle 7 sur laquelle il est rivé et qui appuie sur la face de la pla quette l'.
La plaquette 1 porte un bossage 8 dans lequel peut pénétrer une partie en relief 9 prévue à la plaquette l' lorsque les éléments 2 sont exactement supperposés, c'est-à-dire lorsque le mètre est entièrement plié ou dé plié, ce qui permet de maintenir les éléments 2 dans l'une ou l'autre de ces positions.
Chaque élément 2 est muni d'une ouver ture 10 permettant de rendre visible la ron delle 7 ou la tête 5 sur la face de l'élément 2.
Suivant la seconde forme d'exécution, la charnière comporte les mêmes éléments; ce pendant le ressort à lame 6 est remplacé par un ressort hélicoïdal 11.
Hinge for folding rule. The present invention relates to a hinge for a folding rule.
The appended drawing gives, by way of example, two embodiments of the object of the present invention.
Fig. 1 is a plan view of a first embodiment; Fig. 2 is a sectional view along the line A-B of FIG. 1; Fig. 3 is a plan view of a second embodiment; Fig. 4 is a sectional view along the line C-D of FIG. 3.
This hinge comprises two plates 1 and 1 ', each fixed to the end of the elements 2 of the folding rule which they must join together; to this end, the edges of the plates 1 are folded over the inclined side faces of the element 2 and the asperities 3 provided in the bottom of the plate 1 are pressed into the face of the element 2.
The plates 1 and 1 'are joined by an axis 4 which passes through them and around which they can pivot, in order to allow the meter to be folded or unfolded. This pin 4 is provided with a head 5 under which a leaf spring 6 bears, the ends of which rest on the plate 1. The pin 4 is held by means of a washer 7 on which it is riveted and which presses on the face of the plate.
The plate 1 carries a boss 8 into which can penetrate a raised part 9 provided for the plate 1 'when the elements 2 are exactly superimposed, that is to say when the rule is fully folded or unfolded, which allows to keep the elements 2 in one or the other of these positions.
Each element 2 is provided with an opening 10 making it possible to make the ron delle 7 or the head 5 visible on the face of the element 2.
According to the second embodiment, the hinge has the same elements; this during the leaf spring 6 is replaced by a coil spring 11.
