Definitions

  • EXPANDING I j BRACELET ABSTRACT An expandable metal metal bracelet having two 3 c'aimsmnrawmg staggered layers of links includes resilient connecting mem bers, or bails. joining adjacent links each having two limbs which are inserted into a link and a protrusion locked into the body portion of a link, the protrusion and the two limbs lying normally in a common plane but being relatively angularly twisted out of alignment when the links are spread apart.
  • the present invention relates to improvements to expanding each link in a row being connected to two adjacent links in the other row, by means of bails 'or connecting members, said bracelet being in addition provided with means for returning said bails to their position of rest corresponding to the bracelet retracted state.
  • the resilient means adapted to cause the connecting members or bails to return are constituted by springs of various shapes; in particular, it is known to use springs constituted by blades or leaves inserted into the bails and crushed by the latter as they undergo an angular movement under the influence of a traction exerted upon the links, the bail being biassed to its position of rest in view of the spring elastic strain.
  • the present invention provides a specially simple and efficient approachto the resilient return of the connecting members or bails.
  • a bracelet according to the present invention comprises a flat or substantially flat connecting member or bail formed of two limbs longitudinally arranged in the direction of the links axes, each of said limbs being inserted into one of the two superimposed adjacent links connected by said bail, the latter being provided with protru sions or lugs located in the substantially vertical plane of said bail when at their positions of rest, said protrusions or lugs being locked to the body portion of one of said links and being adapted to spread apart due to the resilient direction of the bail plane, whenever said bail is given an angular movement resulting from the links being spread apart.
  • the bail and the return lug or lugs are located in the same plane; the bail connects two superimposed links, one of its longitudinal limbs being engaged into the upper link, whereas its other limb is engaged into the lower limb, said two limbs being thus locked to each other.
  • the links are spread apart, the bail undergoes an angular movement, whereas the return lug, which is locked to one of the links, resists said movement, and the bail and the return lug, due to their mutual distortion are caused to leave their common plane corresponding to their positions of rest.
  • the mutual resilient distortion of the return lug and of the remaining portion of the bail gives rise to a torque by means of which said lug and said bail are biassed toward their initial common plane, thus causing the bracelet to retract.
  • the connecting member or bail is wide open at the center of the lower'longitudinal limb penetrating into the lower link, and said bail comprises a return lug starting from the center of the upper longitudinal limb and directed downwardly until it reaches a level corresponding to that of the open lower limb of the bail, or slightly lower.
  • the bail is open at its upper longitudinal'limb which penetrates into the upper link, and each of the extremities of the bail open limb is extended by means of return lugs, which are directed toward the inner portion of the bail and are adapted to be locked to the bottom portion of the upper link.
  • FIG. 1 is a cross section of a portion of a bracelet according I to the invention.
  • HO. 2 is a cross section along line llll of FIG. 1;
  • FIG. 3 is a plan view of a lower link, one of the connecting members or bails being at rest and the other being open;
  • F l6. 4 is a cross section of a portion. of another embodiment of the bracelet according to the invention.
  • FIG. 5 is a cross section along line VV of FIG. 41, and,
  • FIG. 6 is a plan view of a lower link, one of the bails being at rest and the other open.
  • the bracelet shown in FIGS. 1 to 3 comprises two layers, or rows, of links transversely arranged with respect to the longitudinal axis of the bracelet; it is composed of upper links 1, 1', 1" and lower links 2, 2, 2 the links of one layer being staggered with respect to those of the other layer.
  • the various links are connected by twos, by means of connecting members or bails 3, 3', 3"
  • Each of said bails comprises an upper longitudinal limb 4 inserted into the upper link 1, and connected by means of vertical members 5 and 5' to the symmetrical lower half-limbs 6 and 6' which penetrate into the lower link 2; in addition, bail 3, in its middle portion, comprises aresilient return lug 7, starting from the middle portion of the bail upper limb 4.
  • return limb 7 At rest, return limb 7 is located in a plane which is very near of that of lower half-limbs 6 and 6'; whereas said half-limbs are locked inside link 2, return lug 7, which is located outside link 2 in a recess 8 of the vertical outer wall of the link, abuts against a lower shoulder 9 starting from the bottom of link 2; accordingly, the bail half-limbs 6 and 6' and the return lugs 7 are slightly distorted with respect to their common plane and are thus resiliently locked to link 2, which biases the upper longitudinal limb 4 of the bail toward the wall of upper link 1.
  • the upper links 10, 10 10" are lined with decorating shells 11, 11, 11"; said links are connected to the lower links 12, 12',12"... by means of bails 13, 13', 13" Bail 13 comprises a lower transverse limb inserted into lower link 12 and connected, by means of vertical members 14, 14, to the two upper half-limbs 15, 15 inserted into the upper link.
  • the adjacent extremities of the upper half-limbs are extended by return lugs 16, 16' turned forward the inner portion of the bail and adapted to be located in a recess 17 of the lower bottom of upper link 10. Moreover, the bail upper corners are locked at 18, 18' to a tongue cut into the upper bottom of the upper link 10.
  • Connecting member or bail 13 is thus locked by means of its upper half-limbs to the upper link, and. at their position of rest the return lugs 16, 16' are inserted within their housing under a slight tension, which slightly withdraws them from the vertical plane of bail 13; when the links are being spread apart, the lower links carry with them the bail lower limb which is trapped by said lower links the bails thus assuming an oblique position, whereas the return lugs, which are locked to the upper links, maintain a substantially vertical position; it results therefrom a dispersion of the lugs and a resilient strain of the upper half-limbs 16 and 16, which biases the links toward their position of rest.
