Description
Dispositif de verrouillage pour crochet de ruban de mesure". Locking device for measuring tape hook ".
Les rubans de mesure destinés à effectuer des mesures longues, sont munis à leur extrémité libre d'un anneau de tirage, associé traditionnellement à un crochet. Plus précisément, l'extrémité du ruban de mesure est rendue prisonnière par rivetage entre, d'une part, une plaque graduée sur laquelle est articulé l'anneau de tirage et le crochet et, d'autre part, une contreplaque de rivetage. Measuring tapes intended to perform long measurements are provided at their free end with a pulling ring, traditionally associated with a hook. More specifically, the end of the measuring tape is made captive by riveting between, on the one hand, a graduated plate on which is articulated the pulling ring and the hook and, on the other hand, a riveting plywood.
Le crochet peut, soit être rabattu parallèlement contre la contreplaque de rivetage, soit être redressé à 90" par rapport à elle pour permettre l'accrochage de l'extrémité du ruban de mesure sur le support. The hook can either be folded parallel against the riveting plywood or be straightened 90 "from it to allow the end of the measuring tape to be hooked onto the support.
Pour faciliter son accrochage sur les divers supports pouvant être rencontrés, le crochet est muni de pointes, crans en saillie qui, lors des manipulations du ruban de mesure, parviennent à blesser l'utilisateur. To facilitate its attachment to the various supports which may be encountered, the hook is provided with points, protruding notches which, when handling the measuring tape, manage to injure the user.
Lorsqu'il s'agit de mesurer des grandes longueurs, il est courant que, malgré la présence du crochet, il soit nécessaire de maintenir l'extrémité libre du ruban de mesure pendant qu'une autre personne développe le ruban de mesure. Il en résulte que le crochet est inopérant et que tout au plus il peut blesser l'utilisateur maintenant l'extrémité du ruban. I1 n'est cependant pas possible de supprimer le crochet car, d'une part, certains utilisateurs en ont l'usage, et, d'autre part, par tradition, il doit être livré avec le ruban de mesure. When measuring long lengths, it is common that, despite the presence of the hook, it is necessary to maintain the free end of the measuring tape while another person develops the measuring tape. It follows that the hook is inoperative and that at most it can injure the user holding the end of the tape. I1 is however not possible to remove the hook because, on the one hand, some users have the use, and, on the other hand, by tradition, it must be delivered with the measuring tape.
La présente invention a pour but de remédier à ces inconvénients en fournissant un dispositif permettant de verrouiller, en position repliée, le crochet associé à un tel ruban de mesure. The present invention aims to remedy these drawbacks by providing a device for locking, in the folded position, the hook associated with such a measuring tape.
Ce e dispositif est constitué par un tenon saillant de l'un des éléments emprisonnant l'extrémité du ruban et apte à pénétrer dans un trou du crochet, lorsque celui-ci est en position rabattue pour le caler en rotation. This e device is constituted by a protruding tenon of one of the elements trapping the end of the ribbon and capable of penetrating a hole in the hook, when the latter is in the folded position to lock it in rotation.
Ainsi, lorsque l'utilisateur n'a pas besoin de crochet et qu'il le replie contre l'extrémité du ruban de mesure, le crochet est verrouillé dans cette position par engagement du tenon dans le trou qu'il comporte et ne risque plus de blesser l'utilisateur. Thus, when the user does not need a hook and folds it against the end of the measuring tape, the hook is locked in this position by engagement of the post in the hole which it comprises and no longer risks to injure the user.
Selon les formes d'exécution, le tenon peut être muni, à son extrémité, de moyens d'expansion élastique assurant un verrouillage temporaire ou, au contraire, être rivé directement sur le crochet. According to the embodiments, the post can be provided, at its end, with elastic expansion means ensuring temporary locking or, on the contrary, be riveted directly on the hook.
L'invention sera mieux comprise à l'aide de la description qui suit en référence aux dessins schématiques annexés, représentant à titre d'exemple non limitatif, une forme d'exécution de ce dispositif. The invention will be better understood with the aid of the description which follows with reference to the appended schematic drawings, representing by way of nonlimiting example, an embodiment of this device.
Figures 1 et 2 sont des vues de côté en coupe transversale du dispositif, respectivement, lorsque le crochet est en position déployée et lorsque le crochet est en position repliée et verrouillée. Figures 1 and 2 are side views in cross section of the device, respectively, when the hook is in the deployed position and when the hook is in the folded and locked position.
Dans ces dessins, 2 désigne l'extrémité du ruban de mesure qui est emprisonnée entre une plaque graduée 3 et une contreplaque de rivetage 4. La plaque graduée 3 est liée à la contreplaque 4 par deux rivets 5. Elle est munie à son extrémité d'un palier pour un axe transversal 6 sur lequel sont articulés, d'une part, un anneau de tirage 7 et, d'autre part, un crochet 8. Ce crochet, qui peut occupé soit la position déployée représentée à la figure 1, soit la position repliée représentée à la figure 2, est muni de dents 9 saillant de sa face qui fait vis à vis au ruban 2 lorsqu'il est replié. In these drawings, 2 denotes the end of the measuring tape which is trapped between a graduated plate 3 and a riveting plywood 4. The graduated plate 3 is linked to the plywood 4 by two rivets 5. It is provided at its end with a bearing for a transverse axis 6 on which are articulated, on the one hand, a pulling ring 7 and, on the other hand, a hook 8. This hook, which can occupy either the deployed position represented in FIG. 1, either the folded position shown in Figure 2, is provided with teeth 9 projecting from its face which faces the ribbon 2 when folded.
Selon l'invention, l'un des deux éléments prenant en sandwich l'extrémité de la lame 2 et, en l'occurence, la plaque graduée 3, est solidaire d'un tenon 10 traversant le ruban gradué et la contreplaque 4 et saillant de cette contreplaque. Ce tenon est destiné à pénétrer dans un alésage 12 ménagé dans le crochet 8. Le tenon 10 peut assurer le verrouillage du crochet en position rabattue, soit de manière temporaire, par coincement, cas dans lequel il possède un diamètre légèrement supérieur à celui de l'alésage 12, ou par expansion radiale, cas dans lequel il est muni d'une tête fendue avec un bourrelet périphérique formant cran de verrouillage, soit enfin de manière définive par rivetage de sa tête sur le crochet, comme montré à la figure 2. According to the invention, one of the two elements sandwiching the end of the blade 2 and, in this case, the graduated plate 3, is integral with a tenon 10 passing through the graduated ribbon and the plywood 4 and projecting of this plywood. This post is intended to enter a bore 12 formed in the hook 8. The post 10 can ensure the locking of the hook in the folded position, either temporarily, by wedging, in which case it has a diameter slightly greater than that of the bore 12, or by radial expansion, in which case it is provided with a slotted head with a peripheral bead forming a locking notch, or finally definitively by riveting its head on the hook, as shown in FIG. 2.
Dans une variante de réalisation, le tenon fait saillie de la contreplaque 4. In an alternative embodiment, the tenon projects from the plywood 4.
