Definitions

  • the present invention relates to a device for the fine adjustment of the useful length of a wrist strap, such as the wrist strap of a watch, comprising two portions and a clasp for connecting the free ends of said portions to allow said free ends to be connected at a specific useful length.
  • a plurality of solutions have already been proposed to make it possible to provide a modification to the initial adjustment of the useful length of a wrist strap, in particular a wrist strap of a watch.
  • This type of adjustment is advantageous, in particular, in the case of clasps known as clasps with folding clips or arms, in which the ends of the wrist strap remain attached to the free ends of the clips or arms of the clasp articulated to one another, such that the useful length of the wrist strap may only be changed by modifying the initial adjustment. More specifically, this adjustment requires the use of tools and a certain degree of dexterity, such that it is not easily accessible to everyone.
  • one of the arms of the clasp is telescopic and comprises a plurality of openings to allow the hooking elements of the other arm to be fixed to different lengths of the telescopic arm.
  • CH 663 522 and WO 03/015562 both comprise, between the two articulated arms, a small articulated link capable of being flipped over into two positions, one in which its length is added to that of the arms and the other in which it is subtracted from that of the arms, making it possible for the useful length of the wrist strap to be varied between two specific values.
  • the object of the present invention is to remedy, at least partially, the aforementioned drawbacks.
  • the subject of this invention is a device for the fine adjustment of the useful length of a wrist strap, such as the wrist strap of a watch, as claimed in claim 1 .
  • the adjustment device which is the subject of this invention has a plurality of advantages, namely that of permitting a virtually continuous adjustment over a range of several millimeters, typically over a range corresponding to half the width of the wrist strap. This adjustment is carried out without requiring the opening of the clasp, which makes the adjustment device much more simple to use than might be imagined. Due to this particularity, the wearer of the wrist strap is made aware in real time of the effect of the adjustment, which allows the wearer to carry out an accurate adjustment, primarily because this device allows the wearer to modify the useful length by very small increments over an adjustment range comprising three to four times more adjusting positions that the known devices.
  • said device is of extremely simple construction and may be very easily disassembled and reassembled to carry out cleaning if required.
  • FIG. 1 is a lateral view of a clasp with folding clips associated with an embodiment of the adjustment device and connected to the two free ends of a wrist strap;
  • FIG. 2 is a sectional view of the adjustment device itself, sectioned along the line II-II of FIG. 3 ;
  • FIG. 3 is a plan view from above of the adjustment device of FIG. 2 ;
  • FIG. 4 is a sectional view along the line IV-IV of FIG. 3 ;
  • FIG. 5 is a plan view from above of the fixed adjustment member of the adjustment device
  • FIG. 6 is a plan view from above of a first variant of the adjustment device
  • FIG. 7 is a fragmented plan view from above of a second variant of the adjustment device.
  • FIG. 8 is a view along the line VIII-VIII of FIG. 11 ;
  • FIGS. 9 and 10 are views similar to FIG. 8 in two further positions of the adjustment device
  • FIG. 11 is a sectional view along the line XI-XI of FIG. 8 ;
  • FIG. 12 is a partial perspective view of the adjustment device showing the internal face of the first adjustment member.
  • FIG. 1 illustrates a preferred embodiment of the invention in which the adjustment device, the subject of the invention, is associated with a clasp with articulated clips or arms connecting the two free ends of the wrist strap and generally known as a clasp with folding clips or arms or even as a clasp with a folding buckle.
  • Said clasp of the known type comprises, therefore, two curved arms 1 , 2 articulated to one another and held in the folded position by separable hooking means (not shown).
  • One of the portions 3 a of the wrist strap is connected by a fixing pin 4 to the free end of the arm 1 of the clasp, whilst the free end of the arm 2 of this clasp is connected by a pin 5 to the adjustment device 6 which is the subject of the invention.
  • This adjustment device 6 essentially comprises a first adjustment member 7 having the shape of a disc connected to the clasp 1 , 2 by means of the pin 5 of which the ends are fixed in two parallel and diametrically opposed fixing tabs 7 c , which extend perpendicularly below the disc forming the first adjustment member 7 .
  • This pin 5 passes through the free end of the arm 2 of the clasp located between the fixing tabs 7 c of the disc 7 .
  • the first adjustment member 7 of the adjustment device 6 is connected by the two curved arms 1 , 2 of the clasp to the end of the portion 3 a of the wrist strap, thus ensuring a fixed position of this first adjustment member 7 relative to the longitudinal axis of the portion 3 a of the wrist strap.
  • This first adjustment member 7 comprises a circular lateral surface 7 a which is used as a guide surface for a second manual adjustment member 8 , also in the shape of a disc provided with a circular edge having an internal lateral circular guide surface 8 f in engagement with the circular guide surface 7 a .
  • These two circular guide surfaces 7 a , 8 f are held in engagement by two locks 10 , as illustrated by FIG. 4 , permitting the internal lateral circular guide surface 8 f to rotate around the circular guide surface 7 a .
  • This second manual adjustment member 8 also forms a cover for closing the adjustment device 6 .
  • the first adjustment member 7 further comprises guide means which, in this example, are in the form of a radially oriented rectilinear guide opening 7 b , parallel to the longitudinal axis of the wrist strap.
  • Said radially oriented rectilinear guide opening 7 b is in engagement with a connecting member 9 , slidably mounted in said radially oriented rectilinear guide opening 7 b .
  • Said connecting member 9 is further engaged, on the one hand, with an arcuate opening 8 a made through the second manual adjustment member 8 and, on the other hand, with one of the perforations 11 for the preliminary fixing and adjustment of the length, made through the second portion 3 b of the wrist strap.
  • the two ends of the arcuate opening 8 a are located on the same diameter of the manual adjustment member 8 .
  • the arcuate opening 8 a has the general shape of a half-ring, of which the center C is located in the vicinity of this same diameter.
  • the external edge of this opening 8 a comprises teeth 8 b for cooperating with the connecting member 9 for the purpose which will be explained below.
  • the role of the teeth 8 b formed along the external edge of the arcuate opening 8 a is to make it possible to retain the connecting member 9 in different positions, when said member 9 is subjected to a centrifugal force relative to the manual adjustment device 8 . Said force may result in placing the wrist strap under a certain amount of tension.
  • a friction disc 13 is further housed between the two adjustment members 7 and 8 .
  • Said friction disc 13 is a curved spring disc, intended to create friction between the two adjustment members 7 and 8 , to prevent the second manual adjustment member 8 from being able to rotate freely relative to the first manual adjustment member.
  • this friction disc 13 is penetrated by the connecting member 9 and is housed in a circular opening 8 c centered on the center C of the arcuate opening 8 a , such that the friction disc 13 is driven in rotation around the center C, when the second manual adjustment member 8 is driven in rotation, thus continually blocking the arcuate opening 8 a.
  • Further means for transmitting the movement between the second manual adjustment member 8 and the connecting member 9 may be conceived to transform the circular movement of the second manual adjustment member 8 into a movement of the connecting member 9 , guided through the rectilinear guide opening 7 b extending in the longitudinal direction of the wrist strap 3 a , 3 b .
  • a connecting rod 14 could be present, one end thereof being articulated to the second adjustment member 8 ′, with the other end being articulated to the connecting member 9 .
  • the angular positioning of the second adjustment member 8 ′ may be obtained by a catch 15 integral with the first adjustment member 7 , in engagement with internal teeth 8 ′ d formed on the internal face of the edge of the second adjustment member 8 ′.
  • the second adjustment member 8 ′′ comprises internal teeth 8 ′′ e , in engagement with a pinion 16 mounted pivotably on the first fixed adjustment member 7 and meshing with a radially oriented rack 17 , parallel with the radially oriented rectilinear guide opening 7 b and parallel with the longitudinal axis of the wrist strap of the first adjustment member 7 .
  • the connecting member 9 is simultaneously in engagement with the rectilinear guide opening 7 b and with the rack 17 .
  • a catch 18 is in engagement with second teeth 17 a for positioning the adjustment device in different positions.
  • the connecting member 29 is integral with an elongated slide 29 a , mounted in a diametrical slideway 27 b , formed in the first adjustment member 27 .
  • This elongated slide 29 a comprises a projection 29 b , 29 c at each of its ends.
  • the second manual adjustment member 28 is guided in rotation by the circular lateral surface 27 a of the first adjustment member 27 and comprises two drive grooves 28 a , 28 b intended to be brought into engagement respectively and alternately with the projections 29 b , 29 c.
  • the drive grooves 28 a , 28 b each comprise a semi-circular, circular arc-shaped, active portion, the two semi-circular portions of the same radius being aligned relative to the same diameter of the second manual adjustment member 28 and offset along this diameter.
  • This variant with two drive grooves 28 a , 28 b intended to be brought alternately into engagement with two projections 29 b , 29 c of the slide 29 a , makes it possible to double the adjustment range relative to the first embodiment.
  • This adjustment range is shown by the movement of the slide 29 a from its position illustrated by FIG. 8 to that illustrated by FIG. 10 and corresponds to a rotation of 360° of the manual adjustment member 28 .
  • said drive groove 28 b comprises an end 28 b 1 located outside its active semi-circular portion, to be brought into engagement temporarily with the projection 29 c at the moment when the projection 29 b is located in the intersection between the drive grooves 28 a , 28 b , as illustrated by FIG. 9 .
  • the groove 28 b is deeper than the groove 28 a and the projection 29 c is longer than the projection 29 b , such that the problem of the intersection is not posed when the projection 29 c passes over the groove 28 a . It may also be observed in FIGS. 8 to 10 that outside the active portions of the grooves 28 a , 28 b defined above, the width of these grooves 28 a , 28 b increases, so that simultaneous guiding is only permitted using a single groove 28 a , 28 b.
  • the center of the second manual adjustment member 28 comprises a circular opening in which a fixed indicator member 34 is positioned which comprises, on its internal face, a diametrical slideway 34 a in engagement with the slide 29 a .
  • the external face of this fixed indicator member 34 , as well as the external face of the second manual adjustment member 28 may advantageously bear guide marks (not shown) to allow the angular position of the second manual adjustment member 28 to be known relative to the adjusting range which extends over 360°.
  • An internal lateral portion of the second manual adjustment member 28 bears angular positioning means 28 c in the form of notches spaced apart at regular intervals around its axis of rotation and intended to be brought selectively and successively into engagement with a folded portion 35 a formed along a resilient positioning member 35 , formed by a leaf spring housed in the first positioning member 27 , as illustrated by FIG. 12 .
