摘要:
The closing device consists of a frame (12) and opposed arms (14) with hook (18) designed to be inserted in the central bolt (20). In the latter, which is bounded below by the base (24) and above by the cross-piece (30) there is arranged in a sliding manner the plate (28) with openings (32), (36) and (34). The latter receives the spring (42) while in the openings (32) and (36) are engaged the hooks (18) of the arms (14). The end (28') of the plate (28) is drawn manually outward and brings about simultaneous unhooking of the arms (14) to which are constrained the band branches. Additional forms of embodiment call for the use of a bolt (60) with pushbutton (68) for simultaneous unhooking of the arms (54) and a bolt (90) with pushbutton (98) which moves opposed shaped plates (94), (94') which constrain the arms (84).
摘要:
The band consists of a plurality of links (20), (22) formed by bringing together four turns (12a), (12b), (12c) and (12d) constrained together by means of pins or equivalent elements inserted in the substantially cylindrical seat which said turns create by partial reciprocal penetration. At least one of said turns and preferably the fourth turn of each link is provided on one side with internal threading into which screws the end (18') of the screw (18) constituting the means of connection between two links (20), (22) and is arranged between the side blocks (30). An alternative form of execution provides that to the branches (42) and/or (44) of the band (40) are connected one or more segments (52) made of metal fabric similarly to the band itself. Said connection is provided by pins inserted in the tubes (54) formed by tube sections (54'), (54''), (54''').
摘要:
To a branch (40) of a metal bracelet applicable to watches is fixed a frame (12) incorporating a movable plate (20); an overturnable plate (14), with end hook (34), is hinged to this frame. Connected with the opposite branch of the bracelet is a fork (10) whose tie (30) is conducted, at closure of the device, to lodge in semicircular seats (26) created in the frame (12). According to a final variant, the closing device consists of two arched sheets (52), (54); on sheet (54) a chamber (66) is obtained in which slides a plate (76) whose front end is coupled below the hook (52') created at one end of the sheet (52).
摘要:
Closing device for watch-straps, bracelets, jewels and similar comprising a plate (12) and pairs of strips (16) hinged together at one end (14) and coupled at the free end to couplable connecting means. These connecting means comprise two hollow bodies (20) and (42) open on the opposite side and a locking element (30) partially inserted in one of the hollow bodies (20) and maintained projecting from said body by means of elastic means (28), said projecting part (36) being insertable and couplable in the cavity of the second hollow body (42). The plate (12) and the strips (16) may be divided into at least two elements hinged together. Alternatively, there may be four elements, a main containing elements and the others becoming gradually smaller so that they may be inserted one in the other.
