Definitions

  • the present invention refers to a closing device for watch-straps, bracelets, jewels and similar.
  • the present invention refers to a closing device for watch-straps, bracelets, jewels and similar, of "wrap-over" type, to open which it is unnecessary to separate the ends of the straps.
  • Closing devices of wrap-over type are well known and disclosed, for example in CH-A-646.852, US-A-2.333.048 and CH-A-660.674.
  • CH-A-646.852 discloses a closing device for watch-straps of wrap-over type including all the features defined in the preamble of claim 1.
  • the known closing devices are designed to overcome the notable problem of the other types of closing devices, with buckle for example, to open which the ends of the strap must be separated, with possible fall of same in positioning phase or following accidental opening.
  • the closing devices for watch-straps of "wrap-over" type generally comprise two plates or strips, curved to adapt themselves to the shape of the user's wrist, which are hinged to each other at one end and, at the other end, are fitted with suitable couplable connecting means to which the strap ends are hinged.
  • said plates or strips are positioned one inside the other, to increase thickness.
  • the device is opened by pulling apart the two strips or plates to decouple the connecting means, while it is closed by bringing the strips close together again by rotating them round their hinging axis.
  • the object of the present invention is to provide a closing device for watch-straps, bracelets, jewels and similar which eliminates the above problems.
  • the object of the present invention is to provide a closing device for watch-straps of "wrap-over" type, provided with a clip which consents rapid opening of same without the drawbacks of traditional closing devices.
  • Another object of the present invention is to provide a device as defined above which permits its immediate opening with simple means, of limited cost and reduced dimensions to avoid trouble for the user and adapt itself to the aesthetic characteristics of the watch-strap.
  • a further object of the present invention is to provide a closing device for watch-straps, watch bracelets and similar with jointed arms, for optimal adherence to the substantially oval-irregular profile of the wrist, conforming to it each time to prevent annoying contacts.
  • the closing device for watch straps of the present invention comprises plates and parallel strips hinged to each other and equipped at the other end with couplable connecting means to which the ends of the watch-strap are hinged, said connecting means consisting of a clip comprising two hollow bodies, hinged to the respective ends of the plate and strips and equipped on the opposite base to the fixing base of an opening, and a laminar locking element or hook, partially inserted in the opening of one of the hollow bodies and kept projecting from said hollow body by means of elastic means, said projecting part being insertable and couplable in the cavity of the other hollow body, in closing phase.
  • a small button fixed on said laminar locking element by means of an appendix permits axial displacement of same in release phase.
  • the closing device of wrap-over type of the present invention also comprises parallel strips or couples of strips and plates fixed by hinges to the respective hollow bodies, composed of at least two elements hinged together.
  • said strips or parallel couples of strips may consist of a main box-type containing body comprising a lowered plate and a plurality of elements hinged together, with decreasing dimensions so that they can be inserted one in the the other, each of said elements being equipped with a lowered seat, which, in closing phase, meets the lowered plate of the main body.
  • the closing device for watch-straps, bracelets, jewels and similar of wrap-over type 10 of the present invention comprises a plate 12 generally, if not necessarily, metallic, which is hinged, by a pin 14, to two parallel strips 16, also generally, even if not necessarily, metallic.
  • the distance between the strips 16 is at least equal to the width of the plate 12, so that it, in the closed condition of the device, may be positioned between said two strips.
  • the closing device or clip described below is applied, to which the two branches 18 of the watch-strap shown partially with dashed and dotted line are hinged.
  • the watch-strap 18 may be of any material, e.g. leather, metal, plastic and similar.
  • the closing device i.e. the means which keeps the plate 12 and the strips 16 inserted one in the other as shown in fig. 2, mainly consists of a clip as described below.
  • the clip comprises a first hollow body or groove 20 of essentially parallelepiped shape, which is fixed in any known way to the end of the plate 12 together with a branch 18 of the watch-strap.
  • the small box 20 is open on the base opposite the hinging base of the branch 18 of the watch-strap and, on the upper face, at the open base, it presents a shaped undercut 22 which, in the constructive form considered, presents the bottom end curved, for example of semi-circular shape.
  • the important dimension of the small box 20 is the width while the height and depth are limited to reduce the bulk of the device to a minimum.
  • the small box 20 On its lower face, i.e. the one opposite the face provided with undercut 22, the small box 20 presents two threaded holes 24, only one of them visible in figure 2, in which two small screws 26 are screwed, preferably grub screws.
  • Two small springs 28 are inserted in the small box 20, which form the elastic means for operation of the clip.
  • a locking element or hook indicated as a whole with 30 is partially housed.
  • the hook 30 consists of a plated body 32 of width lower than or equal to the height of the hollow of the small box 20 so that it can be inserted in same and equipped laterally with two through-holes 34 widened in longitudinal direction in each of which one of the small screws 26 is inserted.
  • the front edge 36 of the plated body 32 is curved to form an invitation to the insertion of same in the other portion 42 of the clip.
  • the plated body 32 presents a shaped appendix 30 constructed in a single body with it, suitable to be inserted in the undercut 22 of the first hollow body 20.
  • the length of the appendix 38 is smaller than the depth of the undercut 22 so that the plated body 32 may slide back and forth with respect to the hollow body 20.
  • the width and conformation in cross-section of the appendix 38 prevent transversal movements inside the undercut 22 and therefore of the plated body 32 in the cavity of the hollow body 20.
  • the appendix 38 is equipped in the central part of the free face with a small button 40, obtained in a single piece with said appendix, which is positioned externally and above the hollow body 20 when said plated body 32 is inserted in the cavity of the hollow body 20.
  • the closing device according to the present invention also comprises a second hollow body or small box 42 fixed to the ends of the strips 16 to which the other branch 18 of the watch-strap is hinged.
  • the second hollow body 42 is also open on one base, in particular on that opposite the open base of the first small box 20, so that itcanreceive and couple, as shown in fig. 2, the edge 36 of the plated body 32 which projects from the first small box 20.
  • the closing device of the present invention is extremely easy to assemble.
  • the small springs 28 are inserted in the cavity of the first hollow body 20 then the hook 30, inserting the appendix 38 in the undercut 22 and pressing the small springs 28 in such a way that the threaded holes 24 correspond to the through-holes 34.
  • the bottom of the hollow of the first small box 20 and the rear face of the plated body 32 may preferably be equipped with suitable seats (not shown in figure) to receive the ends of the springs 28.
  • the screws 26 are then applied, which are inserted in the passages 34 of the plated body 32.
  • the plated body 32 is thus partially inserted in the cavity of the first hollow body 20, with the front end 36 maintained outside this cavity by the thrust of the spring 28 and with the possibility of sliding back and forth inside said cavity thanks to the widened shape of the through-holes 34.
  • Each transversal movement of the plated body 32 is blocked by the appendix 38 which fits perfectly into the undercut 22.
  • the closing operation of the device is rapid and easy as it is sufficient to bring the two hollow bodies 20 and 42 into opposite position, lightly pressing the small button 40; the springs 28 push the hook 30 towards the outside of the hollow body 20, inserting the edge 36 of the plated body 32 in the cavity of the second hollow body 42.
  • Insertion is facilitated by the curved shape of said edge 36.
  • the plated body 32 may alternatively have a C-shape with the two lateral branches in contact with the inside lateral walls of the hollow of the second small box 42.
  • the plate 12 and two parallel strips 16 in figure 1 may be divided into at least two elements hinged to each other.
  • the plate 12 is divided into two plated elements 44 and 46 hinged at their ends 48.
  • the two parallel strips 16 are divided into two parts 50 and 52 hinged together at their ends 54.
  • the distance between the parallel strips is such that, in closing phase of the device, the plated elements 44 and 46 are housed in the inner portion delimited by said parallel strips.
  • This structural layout therefore produces a wrap-over closing device extremely mobile as a whole under the stress determined by anatomical variations, constantly capable of adhering in optimal manner to the wrist profile.
  • Figures 4, 5 and 6 illustrate a closing device for watches, bracelets or similar which, besides a perfect adaptability and adherence to the wrist profile, offer further advantages of strength and compactness.
  • the device is composed of four elements, the first of which is the main containing one and the others have dimensions that grow gradually smaller so that, in closing phase, they fit perfectly one in the other.
  • the main containing element at one end 56 of which one of the branches 18 of the watch-strap or bracelet is connected, consists of two arms 62 and 62′, substantially parallel, interconnected by the crosspieces 64, and 64′, having preferentially the same thickness as said arms and of a crosstie 66 of smaller thickness.
  • Said main element is hinged to the free end at the next element 70 which has dimensions which permit the insertion in the cavity delimited by the arms 62 and 62′ of the crosspiece 64.
  • Said second element 70 is equipped, along the two arms, with lowered seats 72, which meet the crosstie 66 at closure of the device 60.
  • the following elements follow the same layout: in particular, the element 74 is housed in the hollow delimited by the arms of the body 70 to which it is hinged in 76 by means of the pins; while the end element 78 is hinged in 80 to the previous element 74.
  • Both said elements 74 and 78 present lowered seats, respectively 82 and 84, equivalent to the preceding 72, designed to meet in closure the crosstie 66 gradually more and more towards the inside and centrally.
  • a small cylinder 58, integral to the end opposite that of the hinging 80 represents a suitable seat for connection of the device 60 with one branch of the watch-strap or bracelet (not illustrated).
  • fig. 6 shows the arrangement of same with device closed.
  • the arms 62 and 62′ and the crosspiece integrally circumscribe the internal elements 70, 74 and 78 inserted precisely one inside the other, while the thickness of the unit is equal to that of said arms.
  • the abovementioned internal elements meet, through the respective seats 72, 82 and 84, the lowered crosspiece 66 present on the main containing element.
  • the connecting means is inserted between the device 60 and the branch of the watch-strap or bracelet 18.
  • the crosstie 66 may be completely or partly conformed in such a way as to determine a slightly elastically forced connection of one or more of the internal elements 70, 74 and 78 equipped with consequently conformed seats.
  • the plates 44, 46 and 78 may be replaced by shaped bars equipped with grooves for precise positioning and/or locking.
