Definitions

the present invention relates to a folding clasp for a bracelet with a central part with side members comprising at each of its ends a leaflet capable of being folded over and made integral with said central part.
a clasp of this type is already known in which, in the folded position, the leaflets in the form of massive pieces of rectangular section are made integral with the central part with side members by clamping with a notch of their free end on cross members disposed between the side members.
the security of closure of such a device leaves something to be desired by the fact that it is relatively easy to disengage the free ends of the leaflets from the crosspieces on which they clamp.
notch tightening requires a relatively large material thickness of the leaflets not allowing the production of a thin clasp.
the object of the present invention is therefore to produce a clasp for a bracelet, in particular for a watch, having a high closing security and capable of being produced in a thin version.
the leaflets are formed of blades whose profiled outer edge fits notch into the inner edge of the complementary profile of the side members, the security of the closure is increased and the clasp can be produced in a thin version.
the clasp consists of a central part 1 with side members 2 and 3 assembled in their middle by a cross member 4.
a leaflet 5 which, in a first embodiment of the invention is formed by two parallel blades 6 and 7 each assembled in a rotary manner to the side members 2 and 3 by a hinge 9 around an axis 8 set in the side members.
the blades 6 and 7 are separated from each other by a spring 10 shown in Figure 4 and mounted around the axis 8 in the hinges 9.
the blades 6 and 7 are welded to spring cylinders 11 and 12 shown in FIG. 3.
the cylinders 11 and 12, each carrying a bar 14, fit into one another and are separated from each other with the bars 14 by a spring 13 mounted inside the cylinders, around the bars.
Figure 3 shows that the outer edge of the blades 6 and 7 has a profile P1, formed for example of the intersection of two inclined planes and that the side members 2 and 3 have in their inner edge a profile P2 of complementary shape.
the profiles P1 and P2 can be provided over the entire length of the blades and the side members or over only part of this length.
the leaflets 5 When the bracelet is open, the leaflets 5 are spread outwards and the blades 6 and 7 are separated from one another by the springs 10 and 13.
the profiles P1 and P2 interpenetrate against the action of the springs, which produces a mutual approximation of the blades 6 and 7, the profile P1 of which is then inserted into the complementary profile P2 of the stringers.
the blades and the side members are then kept nested by the action of the springs. This ensures, in the closed state, a notched fixing of the blades with the side members.
To open the bracelet simply release the leaflets by removing them outwards against the force of the springs.
the clasp according to the invention can be produced in a thin execution by the fact that the notch fixing is produced using profiles included in the thickness of the blades and the longitudinal members of the clasp.
the security of the fixing is all the higher as the profiles P1 and P2 extend over a greater length in the blades and the side members.
the reliability of the clasp is increased by the fact that the springs 10 and 13 are only very slightly stressed. There is therefore practically no risk of destruction of the springs by repeated fatigue.
the notch fixing effect manifests over a significant length of profiles P1 and P2
the effect of the wear on the edges of these profiles is much less significant than in the case of a notched fixing at a single point.
the spring 10 of the hinges 9 is not absolutely necessary and it can without other means be eliminated. It is also obvious that the complementary profiles P1 and P2 can be interchanged, the profile P1 then being provided on the side members 2 and 3 and the profile P2 on the blades 6 and 7. Likewise, any other pair of complementary profiles can be used.
FIG. 5 shows a second embodiment of the clasp according to the invention in which the blades 15 and 16 of the leaflets, similar to the blades 6 and 7 of the first embodiment are connected to a common base 18 to form the branches of a piece in the form of a tuning fork.
the hinge 17 allowing the rotation of the leaflets 5 around the axis 8 is in one piece and has no spring.
the cylinders 11 and 12 also have no spring and, when the bracelet is closed, the pressure exerted on the folded flyers on the central part 1 allows the interpenetration of the profiles P1 and P2 against the elasticity of the branches of the tuning fork, the notched fixing of the branches 15 and 16 with the side members 2 and 3 being ensured, in the closed state, by the elasticity of the branches of the tuning fork.
the profiles P2 are preferably provided over a certain length of the longitudinal members, adjacent to the central cross-member 4 and the profiles P1 of the blades 15 and 16 of the tuning fork on a corresponding part of at least length equal to or preferably greater than that of P2 profiles.
This second embodiment is therefore considerably simpler in design than that of the first embodiment. It has no spring which makes it makes it even more reliable. It also offers the advantage of allowing precise metering of the pressure of the notch fixing.
Figures 6 and 7 show a third embodiment of the clasp according to the invention in which the leaflets are each formed from a single solid blade 19 fixed to the hinge 17 to allow their rotation about the axis 8. The other end of the blade 19 is fixed to a cylinder 20 carrying two bars 14 allowing the attachment of a strand of the bracelet (not shown).
the profiles P2 are provided over a certain length of the inner edges of the side members 2 and 3, at equal distance between the central span 4 and the ends of the side members.
the profiles P1 of the blade 19 are located on a corresponding central part of the edges of this blade and their length is at least equal to or greater than that of the profiles P2.
the third embodiment of the invention is of very simple design.
it allows the production of a clasp in an economical version and it offers the main advantage of eliminating the milling necessary for the separation of the blades 15 and 16 of the tuning fork of Figure 5, milling which is a source of machining difficulties when 'it is made for example in a stainless steel part.
