    The invention relates to an adjustment system for continuously adjusting the size of a strap, such as for example a watch strap or a belt. The system comprises at least one base intended to be fixed to a part of the strap and a rotating part intended to cooperate with an adjustment element which is formed by a barb and is intended to be connected to another part of said strap, such that the rotation of said rotating part relative to said base creates a movement of said barb which is intended to move the two parts of the strap relative to each other in order to adjust the total length of said strap. The movement of the barb is a translation, the barb is intended to cooperate with a hole in a part of said strap, the barb is fixed to said rotating part and comprises a pinion (11) which cooperates with a rack (31 ), said rack being fixed to the base.

    CORRESPONDING REQUEST
    The present application claims the priority of the earlier Swiss patent application No. 0771/15 filed on May 29, 2015 in the name of ROLAND MECHANICAL LUXURY SA, the content of this earlier application being incorporated by reference in its entirety herein. request.
    TECHNICAL AREA
    [0002] The present invention relates to the field of adjustable straps, such as a watch strap or a belt.
    [0003] More specifically, the present invention relates to a system allowing continuous adjustment of the size of a strap, such as a watch strap or a belt.
    STATE OF THE ART
    [0004] Straps for a wristwatch with clasps or buckles are known in the art and have different shapes. Usually, such belt straps consist of a continuous part with two ends which are joined by a buckle or clasp mechanism. One problem with the known embodiment is that it allows only fixed sizes and not a continuously adjustable waistband / strap size.
    In the rest of the present description, the notion of belt or strap will be used interchangeably, the principle of the present invention applying to any equivalent product, the latter being a bracelet or a belt or another similar product and not limited by its end use or application.
    [0006] Mechanisms have been developed in the past to provide an option of fine and continuous adjustment of a strap with moving parts.
    [0007] For example, Figures 1A and 1B show a first example of an adjustable mechanism for a strap. The mechanism comprises a base plate 3 fixed to one end of the strap via the axis 4, a turntable 2 mounted on the base plate 3 and a movable barb 1. The barb 1 is guided in a calibration groove 20 and moved from the position of figure 1A to the position of figure 1B by the rotation of the plate 2 relative to the plate 3. The displacement of the barb 1 in the groove 20 allows a longitudinal movement of the barb as illustrated by the arrows in Figures 1A and 1B which are under the plate 3. As the barb 1 is introduced into a hole in one end of the strap and the other end of the strap is attached to the plate 3, the longitudinal movement of the barb 1 in the groove 20 allows fine adjustment of the size of the strap.
    [0008] Other examples of clasps allowing adjustment of the length of a strap or buckle are for example given in the following documents: EP 1815765, EP 1981365, CH 702523, WO 2008064931, GB730846 and WO 2014/033662.
    Summary of the invention
    An object of the present invention is to improve the clasps and buckles known from the prior art.
    [0010] Another object of the present invention is to provide a system which allows precise adjustment of the size of the strap and also a stable position and an adjusted length of the strap once the desired length has been chosen.
    [0011] The embodiments of the present invention are defined by the independent claims of the present application and the embodiments are defined by the dependent claims.
    BRIEF DESCRIPTION OF THE DRAWINGS
    The present invention is defined by the object of the claims and the accompanying drawings which show:<tb> <SEP> Figures 1A and 1B illustrate a system of the prior art.<tb> <SEP> Figures 2A to 4C illustrate principle views of an embodiment of the invention.
    DETAILED DESCRIPTION
    [0013] The invention and its illustrative and non-limiting embodiments are now explained with reference to the figures.
    The adjustable system attached to a strap or belt according to the invention mainly comprises (see Figures 2A and 2B) a base plate 30 fixed to one end of the strap / belt on which is mounted a rotating plate 14, which carries the barb 10 which is attached to the other end of the strap / belt, for example by introduction into a hole in said strap / belt. As explained with reference to Figures 1A and 1B, the barb 10 has a translational movement which is imparted by the rotation of the plate 14.
    In the present invention, the means allowing this transformation of a rotation into a translational movement are explained with reference to Figures 3A to 4C.
    In Figure 3A, a side view of the movable parts of the adjustment system is illustrated. These parts include the plate 14, a pinion 11, a pin 12, a friction wheel 13 and the barb 10.
    An example of manufacturing said set of moving parts is illustrated in the exploded view of Figure 3B. The plate 14 can be screwed into the barb 10 and include a square profile corresponding to a corresponding square profile of the barb so that a rotation of the plate 14 will also be imparted to the barb 10.
    [0018] Figure 3C illustrates a top view of the adjustment system without the plate 14. It comprises a base 30 with a rack 31, a rolling groove 32 and a friction spring unit 33.
    The rack 31 cooperates with the pinion 11 of the barb 10 so that a rotation of the pinion 11 (effected by a rotation of the plate 14) will move the pinion 11 in a translational movement along the rack 31 guided in the groove 32 by the axis 12 thus ensuring the size adjustment function between a tight position and a loose position. Typically, the tight position is when the barb 10 is close to axis 4 and the loose position is when the barb 10 is moved away from axis 4.
    Figure 3D illustrates a side view of the adjustment system in the clamped position and Figure 3E, a front sectional view of the system without the plate 14 in the same position as Figure 3D.
    Figures 4A to 4C illustrate the adjustment system passing from a loose position (Figure 4A) to a tight position (Figure 4C), each time with a side view and a top view without plate 14, but the passage from one position to another being achieved by a rotation of the pinion 11 along the rack 31, for example by the rotation of the plate 14.
    [0022] Preferably, the friction spring unit 33 comprises a ball mounted on a spring which creates a "clicking effect" upon rotation of the plate so that a user will feel and / or hear the movement of the plate. rotation.
    [0023] The system can be stopped in any position (from loose to tight and vice versa) and remains in a stable position when stopped. This is in particular due to the high friction of the barb 10 in the belt hole, thus preventing its unwanted rotation (and change of the fit size) by pulling on the strap / belt.
    The system according to the invention thus allows a very fine and simple adjustment to the position desired by the user, by the use of simple means.
    The system of the invention can be made of any suitable material, for example metals, precious metals, alloys or others such as synthetic materials, mixture of materials, etc.
    [0026] Preferably, the system according to the invention is used with a watch strap for a wristwatch. However, the system can be used with other objects, similar or not, such as belts, helmet straps etc.
    [0027] The examples given in the present description are only illustrative and should not be interpreted in a limiting manner. Different embodiments of the present invention can be combined depending on the circumstances.
