  The present invention relates to a closure device

  for bracelets, with or without watch, having essentially a thick

  It is extremely small, but at the same time perfectly functional, light, compact, and economical, and looks very beautiful. As for its structural characteristics, this device adapts well to the contours of the bracelet without the presence of projections or points capable of being caught in the fabric of clothing. Maneuvering the device, either by closing or opening, is facilitated by the simplicity of the object and the reduced number of components. These components, in the assembly phase, reduce the time

  of work and the. labor force with significant savings in

  and consequential benefits of an economic nature.

  The invention thus relates to a closing and opening device for bracelets forming an integral part of the bracelet as such and placed at the junction point, that is to say at the closing point.

and opening the room.

  The device is composed of two parts: a part

  at one end of the bracelet, the other part being attached to the ex-

  opposite end. Because the bracelet forms a circle around the arm, the two parts meet at the junction point, where the device

  intervenes to perform the intended function.

  Seen from the outside, the device has only two rectangular plates contiguous to each other longitudinally (but transversely to the bracelet) at the closing point

of it.

  One of the two pads is stably attached to one of the stapling and unhooking ends of the bracelet, while the other pad is hinged to the other staple end of the bracelet. Between these two closing and opening ends of the bracelet is disposed the normal and known safety tab, foldable

  like a wallet. This foldable tongue, once closed the bra-

  celet, is completely covered and concealed.

  This group of two plates comprises the entire device for closing and opening the bracelet, this device being made, in essence, firstly by means of a groove with a curved bottom formed longitudinally along a side of the plate attached to one end of the bracelet and, on the other hand, by means of a curved element intended to engage in said groove, the whole being lockable by means of a hole drilled right through the tongue safety

  at one end thereof, and a closing and locking latch

  cage, having a peripheral groove, provided in a corresponding position

  laying at the other end of the tongue.

  In practice, it is sufficient, to close the bracelet after placing it on the arm, to fold the safety tab, to attach the

  rectangular inserts, and press lightly up and down the

  said pads to ensure that the curved element enters the groove

  longitudinal and the pawl is snapped into the hole of agra-

corresponding fage.

  To release the bracelet simply lift the hinged plate with a fingernail and tilt it around its pivot, thus ensuring not only the release of the plate itself, but also that of the pawl, whose peripheral groove can

  then unhook from the clamping and locking hole.

  The accompanying drawings illustrate the invention to render it

understandable.

  Figure 1 is a perspective view of a bracelet with the device according to the invention, completely closed;

  FIG. 2 is a perspective view of the bracelet, illustrated

  FIG. 1, seen at the moment of putting it on the arm or its

  lift, with the safety tab open around its central hinge; Figure 3 is a side view of the closed safety tab and without a bracelet, but carrying the end plates of the bracelet, that is to say the closing means; Figure 4 is a plan view of the object of Figure 3, i.e. the safety tab; Figure 5 is a side view of the safety tab of Figure 3, in the open position; Figure 6 is a plan view of the tongue of Figure 5, in the open position; Figure 7 is a cross-sectional view of the closed device, taken along line VII-VII of Figure 4 and further on a larger scale; FIG. 8 is a view of the object of FIG.

this time open.

  Outside the bracelet 1, when it is closed (FIG. 1), only two rectangular plates 2 and 3 are seen. When the bracelet is open (FIG. 2), we see a safety tab 4 which is articulated around its central hinge 5 and which is composed of two parts 6 and 7, provided with a hole P pierced p * rt at one end and the other part of a pawl 9 being at the opposite end. It is important to pay attention to Figure 8, given for

  explain in a very simple way the essential functioning of the

  positive according to this invention. In fact, the bracelet, not shown, is attached by its ends respectively to the plates 2 and 3 and more precisely to the flanks 11 and 12 of said plates. The plate 2, fastened integrally to the part 6, is provided on its right side with a longitudinal groove 2 ', the part 6 being furthermore pierced right through the hole 8 at the end near the point of attachment. . The plate 3, fixed by a hinge and pivoting about a pivot 13 of the part

  folded 7 ', door below a pawl 9 provided with a peripheral groove

10.

  To ensure the closing of the device, it is necessary to join the plates 2 and 3 so that the folded portion 7 'of the wafer 3 can enter the groove 2' of the wafer 2, and the

  ratchet 9 with its groove 10 is above the hole 8; thus in

  the parts slightly up and down, these parts, ensuring the

  meture, enter their respective closures.

  Finally, to open the device, it is necessary to exert on the plate 3 a slight traction by rotating it angularly about its pivot 13, so that it is possible to

  clear the groove 2 'and allow the pawl 9 to unhook.

  The light elasticity of parts 6 and 7 is enough to make it flexible and easy

  opening and closing clicks.
