Definitions

  • the present invention relates to a clasp for connecting two ends of one or more bands, for example the two ends of the strap of a belt. More particularly, the invention relates to a clasp having a removable part.
  • the belt thus allows adjustment of the useful length without opening the clasp, which is an advantage compared to a pin buckle type clasp, in which the pin must be completely removed from the hole in which it is inserted in order to then be able to remove it. insert into another hole.
  • the length adjustment using so-called “automatic” clasps is also finer, allowing the length of the belt to be adjusted more finely, thus making it more comfortable for the wearer.
  • US2015113770 (A1 ) And US9149090B1 are examples to illustrate the general objective of increasing the comfort of the wearer of a belt, for example by allowing easier and finer adjustment.
  • An objective is to provide a clasp allowing the length of a belt to be shortened without opening the clasp and/or without activating an actuator to unlock a stopping mechanism.
  • An objective of the invention is to facilitate the passage of the wearer through a metal detector, used as part of a security check, for example in airports or in access areas to a protected or secure site or building.
  • Belt clasps as described above, are made of metal. To pass a metal detector, it is necessary to remove the belt with its metal clasp in order to avoid a false alarm. As the belt is normally held by the loops of a garment, it can be very inconvenient to remove it, depending on the clothing worn. Generally it is necessary to remove the belt from the loops of pants, which is often an unpleasant operation to undertake in public.
  • the invention seeks to allow finer and/or more precise adjustment, compared to belts using a toothed belt. It is also an objective to provide a clasp which can be used with a higher number of pre-existing belt straps and/or without the need for a strap adapted to the clasp.
  • the invention seeks to offer a belt wearer a greater choice of combinations of different clasps with different belts. For example, a wearer may wish to spontaneously choose a belt and/or clasp color that matches the colors and patterns of their clothing, or colors and patterns that match their current mood.
  • An objective of the invention is also to provide a clasp having a harmonious and aesthetic exterior appearance, presenting, for example, reduced dimensions and/or homogeneous and rounded contours, and preferably devoid of protruding elements, such as for example a side operating lever, likely to get caught on clothing.

  • this mechanism is associated with a body of the clasp.
  • the useful length we generally mean the length of the defined perimeter by the belt or band when the two ends are connected and the relative longitudinal movement between the two ends is blocked by the clasp in at least one direction.
  • the useful length is therefore the length such that it can be adjusted by a user using the clasp.
  • the “absolute length” of a belt refers to the fixed length of the belt band, which in general can only be shortened by cutting the band. Such shortening of the strip is generally carried out near the end opposite the end carrying the rack. It can be done in advance to roughly adapt the belt to the size of a particular wearer. This type of length change is generally not linked to the adjustment of the useful length in accordance with the present invention.

  • the useful length adjustment mechanism allows the length to be adjusted to a value chosen from a plurality of discrete values, like the mechanisms of the embodiments shown in figures 1 to 9B .
  • the fineness of the length adjustment is then preferably determined by the spacing of the teeth of a rack arranged on one of the ends of the strip.
  • Another possibility is to have a mechanism for adjusting the useful length which allows continuous adjustment, without a rack, like the mechanism of the embodiment shown in the figures 11 to 14 described further below.
  • the rack is generally arranged near the "free" end of the band, that is to say the end which can be completely separated from any element of the clasp (except the rack) when the clasp is open.
  • the tooth spacing of the rack may depend on the type and use of the clasp.
  • the teeth are spaced at a distance of 0.2-1.5 cm, advantageously 0.3-1 cm, and preferably 0.35-0.8 cm.

  • the first face 83 is the exterior face which is visible when the belt is worn on clothing
  • the second face 84 is the interior face, which is turned towards the body of the wearer and is therefore not visible when the belt or the wristwatch is worn.
  • the clasp 10 is arranged to allow the complete separation of the first free end 81 from the body 20 of the clasp, which is usual in the case of a belt clasp.
  • Grace at this separation it is possible to put the belt on a piece of clothing by threading the free end 81 through loops provided for this purpose, before joining the free end to the body 20 of the clasp to secure the first and second ends. 81, 82 of the belt.
  • a particularity of the clasp 10 concerns the possibility it offers of detaching, manually and easily, the body 20 of the clasp from the second end 82 of the strip 80, thanks to a coupling device 50 secured to the second end 82 , and a locking mechanism arranged on the body 20 to allow the coupling device 50 to be attached to the body 20.

Instead of a pair of opposite legs 74, it would also be possible to provide a second transverse spacer at the same end of the longitudinal members 71, for example, in order to define the closed contour of a passage for the strip 80, similar to this which has been described above with respect to the channel 46 formed by the pivoting element 40.
  • each of the two lateral sides of the body 20 has a niche arranged to receive the ears 45a and 45b of the pivoting element 40, as visible in the figure 1 . Thanks to the niches 66, the lateral dimensions (in the transverse direction) of the pivoting element 40 do not exceed or only slightly the corresponding lateral dimensions of the frame 70 and the coupling element 22.
  • the entire clasp has a homogeneous appearance, generally longitudinal and thin, with a transverse extension (width) adapted to that of the band 80.

  • the niche 68 is provided for receive the blocking element 41.
  • a rod 69 extended by a spring 75 is housed in each of the blind holes 67. As shown in the figures 4A-4C and visible in the Figure 5 , the rods 69 are supported against a lower face of the blocking element 41, and by this means, urge the pivoting element 40 towards the rest position shown in the figures 1, 2 4B , And 5 has 7 .
  • the body 20, in particular the frame 21, the pivoting element 40, the guide structure 30 and the springs 75 form the device for adjusting the useful length of the belt, whose operating principle will be described with reference to Figures 4B and 4C .

  • the strip 80 is framed by the body 20 and the rack 85 (also shown in the figure 2 ) faces the blocking element 41 of the pivoting element 40.
  • Two springs 75 on which rods 69 are arranged, bias the pivoting element 40 in the counterclockwise direction as shown in the Figures 4B and 4C , which means that the free end of the blocking element 41 is pushed into the gap between two teeth of the rack.
  • the actuating lever 42 is biased towards a rest position, in which it is placed precisely in the notch 73 made to measure to accommodate its free end.
  • the teeth of the rack 85 have an asymmetrical profile and comprise, in profile view as shown in the Figures 4B and 4C , a first sidewall 76 which is shorter (or smaller) and practically vertical (or closer to vertical than horizontal), and a second sidewall 77 opposite the first sidewall, which is longer (or larger) and whose inclination is closer to the horizontal.
  • the blocking element 41 is made in the form of a pad whose end butts directly against the first flank 76 of a tooth, in order to block any movement of the first end 81 in the direction corresponding to an extension of the length useful from the belt.
  • the guide structure 30 is arranged to prevent the strip 80 from moving away from the blocking element 41 beyond a predefined distance, so as to prevent the rack from disengaging from its engagement with the blocking element 41.
  • the actuating lever 42 has been raised to move to the activated position of the adjustment device. This pivoting caused the blocking element 41 to be lowered against the springs 75. In particular, the blocking element 41 is lowered into its niche 68 to free the passage between the guide structure 30 and the body 20 . In the configuration shown in the figure 4C , the blocking element 41 is disengaged from the rack 85, which is why the first end 81 of the strip can now be moved in both directions in the longitudinal direction. It is also possible to completely separate the first end 81 of the clasp, as shown in the figure 1 , for example in order to remove the belt of the garment.
  • the length adjustment device does not prevent the movement of the first end 81 in the direction corresponding to the shortening of the useful length of the belt (towards the right at Figures 4B and 4C ).
  • a user can grab the strip 80 upstream of the clasp (on the left side in the Figures 4B and 4C ) to push the first end 81 so as to shorten the useful length by pushing the strip 80 further through the guide structure(s) 70, 46, 30 of the clasp.
  • the user can grasp the free end 81 as it emerges from the guide structure 30, to the right in the Figures 4B and 4C , to exert traction.
  • the second side 77 of a tooth of the rack will then communicate the force exerted in pushing or pulling to the blocking shoe 41. Due to the orientation of the cooperation surfaces between the shoe 41 and the second side 77 of the asymmetrical teeth , this force causes the lowering of the pad 41 against the springs 75 and therefore causes the pivoting element 40 to pivot slightly in the direction of unlocking, as in the case of activation by a user who has grasped and lifted the lever actuation 42. Thanks to the shapes and/or orientations of the cooperating structures between the rack 85 and the blocking element 41, it is not necessary to activate the activation member 42 to shorten the length useful. These characteristics allow very easy and easy shortening without creating the risk of accidental opening of the clasp.
  • the clasp 10 further comprises a coupling device 50 which is secured to the second free end 82 of the strip 80, said second end being the end opposite the (free) end comprising the rack.

As the body can be detached easily and/or manually from the two ends of the strip 80, thanks in particular to the coupling device 50 at the second end, it can be made of metal, but it can be made of other materials if desired.
  • the coupling device 50 comprises a support 52, said first coupling element 51a, 51b being arranged on said support, said body 20 and said support 52 forming a male-female assembly arranged to guide said coupling device 50 relative to the body 20 during the coupling of said first and second coupling elements 51, 22 by a user.

  • the blocking element On its rear face, facing the frame 321, the blocking element comprises a blind hole 12, designed to receive one end of a cylindrical spring 14, the other end of which rests in a housing arranged between the central part 367 and the frame 321. This spring urges the blocking element towards a limit elevation position, towards the interior face 84 of the strip 87, as visible in the Figures 13A to 13C .
  • the blocking element 349 further comprises, at its two lateral sides, support surfaces 17. These surfaces are located in an oblique transverse plane, facing a pair of pads or plates 341 connected to the element pivoting element 340.
  • the plates 341 are arranged on the transverse element 44 of the pivoting element, similar to the blocking element 41 of the previous embodiments, with the difference that it has two plates and that they are arranged laterally on the transverse 44, in order to leave space between them for the apex 15 of the blocking element 349.
  • the central part of the transverse 44 functions as a stop for the blocking element 349, preventing it to exceed, under the effect of the spring 14, a limit elevation in the absence of a strip 87 inserted in the clasp.
  • a blind hole 367 is also arranged on the upper face of each of the uprights 97, to accommodate a rod 69 extended by a spring 75.
  • the rod 69 rests against the lower face of each of the plates 341, in order to bias the entire pivoting element 340 into the rest position.
  • the arrangement of the blocking element and the pivoting element 340, the other segments and/or parts of the clasp are substantially identical, analogous or very similar to what has been described above with respect to to the previous embodiments, and identical reference numbers are used in the Figures 10-14 when the structure and/or function of a structural element is largely identical to a corresponding element shown in a previous figure, and the person skilled in the art will have no difficulty in understanding the operation from the description of the structure previously given above.
  • the frame 70 and the guide structure 30 of the clasp 130 are structurally almost identical to the corresponding elements of the clasps 10, 110 and 120.
  • the guiding and stabilization of the first end 81 of the strip 87 is obtained by the frame 70, the passage 46 in the pivoting element and the structure 30.
  • the segment 321 of the clasp forming the frame comprises the locking device with its actuating members 23, the opening 325 for inserting the coupling device 350 and for housing it and attaching it detachable manner in the housing 324.
  • the opening 325 is similar to the opening 125 of the clasp 110, but a little more extended in the radial direction.
  • the cross section of the coupling device 350 presents, at the level of its support 362 (cutting plane CC of the Figure 14 ), two axes of symmetry (S1-S1 and S2-S2) as in example (iii) illustrated in Figure 4E .
  • reducing the number of axes of symmetry of the support is not the only way to prevent the risk of incorrect and/or erroneous attachment of the coupling element 51 with the coupling element 322 of the body 320.
  • Other structural adaptations may serve this function.
  • the arrangement of the coupling elements 51 and/or the holes 22a, 22b ( fig. 4D And 8 ) can be used to allow connection in a relative orientation only between the first and second coupling elements 51, 322.
  • the openings 22a and 22b are located downward at the bottom of the housing 124 (shown at the top in the view of the fig. 8 ).

  • openings 22a and 22b are provided like the corresponding openings shown in 4D figures And 8 .
  • the connection and detachment of the coupling device 350 from the second coupling element 322 operates in a manner analogous to what has been described above regarding the other embodiments.

  • Swiveling pivot element 340 causes the lowering of the plates 341, which come into contact with the bearing surfaces 17 of the blocking element to act on the latter and make it pivot downwards, in a clockwise direction at fig. 13A-C .
  • This pivoting separates or at least loosens the contact between the blocking element and the interior face of the band 87, which allows the wearer to pull on the part of the belt upstream of the clasp to remove the first end of the band outside. of the latter, or simply to extend the useful length.
  • the arrangement and/or structure of the blocking element 349 also allows the shortening of the useful length without the need to activate the actuating element 42.
  • the user grasps the strip upstream of the clasp and pushes it into the direction of shortening. In this case too, the force exerted by the user acts on the blocking element. However, in this case, the blocking element is caused to pivot clockwise. In other words, in the direction associated with a widening of the passage 31. The first end 81 is thus further inserted into the clasp and the useful length shortened.

  • the mechanisms of the clasps of the invention are advantageous among other things because a separate lever activation member, for example lateral, forming a protuberance and/or emerging from the general contour of the clasp is absent.
  • the activation member constitutes, is integrated and/or forms part of a cover exposed towards the outside of the clasp and is preferably flat.
  • the activation member 42 is made in the form of a pivoting plate. The absence of a protruding side lever reduces the risk of the clasp catching on clothing, for example.
  • the clasp comprises a cover and/or a cover 48, and the actuating element 42 is integrated into said cover and/or forms at least a part of said cover.
  • the cover preferably defines at least partially the main exterior face 48, the in front and/or the front of the clasp, exposed and thus visible from the outside when the clasp is worn and in the rest position.

  • a cover 48 or part of the latter is formed by the entire actuating element 42.
  • Another modification planned in the context of the invention would be a first coupling element 51 formed by a single protuberance instead of the two protuberances 51a and 51b.
  • the invention envisages the inversion of the male and female parts, respectively, of the male-female assembly, for example so that the female part is associated with the coupling device 50, 150, 250, 350 and the male part to the body 20, 120, 320.
