Definitions

  • the present invention concerns the field of adjustable straps, such as watch strap or belts. More specifically, the present invention concerns a calibration system allowing a fine and precise adjustment of the size of a strap such as watch strap or belt and other similar products.
  • Straps for wrist watches with clasps or buckles are known in the art and they have different shapes.
  • figures la to 1 c illustrates a first example of a first clasp mechanism with a lever 1 , a pin 3, the Sever 1 comprising an axis 4.
  • the strap comprises two ends 5, 6, the lever 1 being fixed to the end 6 via axis 4 and the pin 3 penetrates into hole 51 of the other end 5 of the strap.
  • the pin 3 is freed from its hole 51 and the position, of end 5 may be moved relatively to end 6 of strap.
  • the lever 1 is moved downwards such that the pin 3 penetrates into a hole 51 of the end 5, in order to block the relative movement of the two ends 5, 6.
  • An aim of the present invention is to improve the known clasps and buckles of the prior art.
  • Another aim of the present invention is to provide a clasp that allows a fine and symmetrical adjustment of the size of the strap/belt and also a stable position and adjusted length of the strap/belt once the desired length has been chosen.
  • the system for a fine and precise adjustment of the size of a strap comprise at least a plurality of balls which are driven in rotation thereby acting on an actuating element with at least one pin linked to a movable part of the strap/belt, said actuating element moving in a longitudinal groove such that said rotation of the balls creates a rectilinear motion of the actuating element that moves two ends of a strap/belt relatively to each other to adjust the length of said strap/belt.
  • the adjustment system may comprise a top plate that rotates relatively to the platform.
  • the balls are placed between said top plate and said platform and are in friction engagement with the top surface of the platform and the bottom surface of the top plate such that rotation of the plate relatively to the platform induces a rotation and circular movement of the bails.
  • the bafts are preferably rubber balls. Other materials are also possible in the frame of the present invention.
  • the platform is preferably made of metal or another equivalent or suitable material.
  • the top plate preferably comprises a glass, such as a sapphire glass.
  • the fop plate may not comprise a glass.
  • the actuating element is preferably attached to a chain at one end of said chain, and the other end of said chain is attached to the platform on which the balls are placed. In one embodiment, the actuating element is attached to a loop which encloses the balls. In one embodiment, the !oop is a chain loop.
  • the invention concerns a strap, such as a watch strap, or a belt with an adjustment system as defined herein. in one embodiment, the invention concerns an object in combination with an adjustment system as defined as defined herein or a strap as defined herein.
  • the invention concerns a door knob with a system as described herein.
  • FiguresIA to 1C illustrate a clasp or buckle of the prior art used on a belt or a watch strap.
  • Figures 2A to 2C illustrate side and top views of the principle of an embodiment of the invention
  • FIGS 3A, 3B and figures 4A and 4B illustrate details of an embodiment of the invention
  • FIG. 5A to 5C illustrate another embodiment of the invention
  • Figures 6A to 6C illustrate another embodiment of the invention.
  • the adjustable system attached to a fixed strap or half of a belt comprises mainly (see figures 2A and 2B) a platform 10 which is attached to the belt or strap 6.
  • This platform comprises a longitudinal groove 1 1 in which moves an actuating element 32.
  • the actuating element 32 comprises two pins 33 and 34 which are meant to be introduced into holes 51 of a movable part of the strap/belt 5.
  • the actuating element 32 is attached to a first end 30 of a chain 31 the other end 13 of which is attached to a side of the platform 10.
  • the element may comprise only one pin 33 or 34.
  • Said volume is filled with balls 12 (see figure 2C for example) which are held by friction between the top surface of the platform 10 and the bottom surface of the plate 20.
  • FIG. 5A to 5C illustrate another embodiment of the present invention.
  • the principles exposed above in relation to the first embodiment apply here as well with the same reference numbers used for the same elements, unless described differently.
  • the chain 31 is replaced by a loop 301 which is filled with bails 12.
  • FIGS 6A to 6C illustrate another embodiment of the invention.
  • the loop 301 is replaced by a chain loop 302 which is also filled with balls 12.
  • the chain loop 302 ends are fixed to the eiement 32 at 303 such that when the balls are rotated and move to the right, the chain loop 302 also moves to the right (as illustrated by the arrow in figure 6B) thus pulling the actuating element 32 to the right as well.
  • this allows an adjustment of the belt/strap on which the system is mounted.
  • the system of the invention may be made in any suitable material, for example metals, precious metals, alloys etc.
  • the balls 12 are made of a synthetic material such as rubber.
  • the platform 10 may be made of a precious material, or metal such as gold.
  • the plate 20 may comprise a transparent glass, such as a sapphire glass.
  • the chain 31 is preferably made of metal. The chain may be replaced by an equivalent element that is rigid or not. if the bails 12 are made of steel or another hard material, then the platform 10 and the plate 20 should preferably comprise an inlay for protection purposes.
  • the system according to the invention is used with a watch strap for a wrist watch.
  • the system may be used with other objects, similar or not, such a belts, helmets etc.
  • system of the invention may be used in a door knob. Any other application may be envisaged as well, where a rotational movement is transformed into a longitudinal movement.
  • the examples given in the present specification are only for illustrative purposes and should not be construed in a limiting manner. Other constructions are possible using equivalent means and within the spirit and scope of the present invention.

Abstract

L'invention concerne un système de réglage pour un réglage correct et précis de la dimension d'une sangle, telle qu'un bracelet de montre ou une ceinture, comprenant au moins une pluralité de billes (12) qui sont entraînées en rotation, en agissant ainsi sur un élément d'actionnement (32) ayant au moins une broche (33, 34) reliée à une partie mobile de la sangle/ceinture, ledit élément d'actionnement (32) se déplaçant dans une rainure longitudinale (11) de telle sorte que ladite rotation des billes (12) crée un mouvement rectiligne de l'élément d'actionnement (32) qui déplace deux parties (5, 6) d'une sangle/ceinture l'une par rapport à l'autre pour régler la longueur de ladite sangle/ceinture.
