摘要:
The present invention relates to the field of chain straps, in particular to an easy-to-disassemble length-adjustable chain strap, including: several middle chain links, wherein one end of each middle chain link is inserted with a connecting needle with an end exposed to the outside of the middle chain link; and one part of each pulling component is fitted into each middle chain link, and the other part of the pulling component is rotatably inserted into one edge link I correspondingly. According to the present invention, the length of the chain strap can be easily and conveniently adjusted by hand without using any tools under normal conditions. The way of adjusting the length of the chain strap is: gently pulling the edge link I outward with fingers and then rotating the same at a small angle to directly disassemble two adjacent middle chain links.

A ceramic watch chain is disclosed. The ceramic watch chain includes a central connecting piece having on both sides thereof a pair of through holes, an outer connecting piece located outside the central connecting piece and having on both sides thereof insert holes corresponding to the through holes, with a fastening groove being formed outside each of the insert holes and having a diameter larger than that of the insert hole, a fastening pin passing through the through holes to be inserted into the insert holes, and a fixing member coupled to a lower surface of the fastening groove. The invention has no pin insert hole on the back of the outer connecting piece of the watch chain, thus providing an attractive appearance, and reducing the manufacturing cost of the watch chain.

The assembly device is intended for the pivoting attachment of at least two components (M1, M2). It comprises a screw (4) intended to be screwed into a first component (M1) and bearing a guide pin (5) guiding the pivoting of a second component (M2). According to the invention, the pin (5) comprises at least one rotation-prevention zone (540) having a shape designed to collaborate with a zone of corresponding shape of the first component (M1), so as to prevent said pin from rotating.

Housing insert for a spacer of a ceramic link for a bracelet, including a housing for receiving a spacer having one end. It includes an external machined portion arranged to cooperate with this housing and an internal machined portion including a substantially cylindrical bearing area, arranged to closely receive this end and having a smaller diameter than that of this end. An equipped link includes such a link and such an insert of this type fixed in this housing. A bracelet including includes a plurality of equipped lateral links into which removably mounted spacers are driven. This bracelet includes intermediate links assembled to pivot freely relative to these spacers or relative to pins pivotably mounted in these equipped links.

Hinged bracelet (100) including a first component (6) hinged with a second component (9) by a hinge (8) along an axis (D).A single-piece, resilient compensation element (1) is imprisoned between said first and second components (6; 9) to prevent any direct contact between said components radial to said axis (D), and to limit the relative angular travel thereof and includes, on either side of a central extensible layer (2), at a first end at least one first extensible and compressible boss (3), and at a second end at least one second extensible and compressible boss (4), said first boss (3) and said second boss (4) projecting relative to said layer (2) and having a larger section than that of said layer (2) in a plane perpendicular to said axis (D).

This bracelet comprises a plurality of articulated elements (1) in which one transverse edge of each element is interlocked in a transverse edge of an adjacent element, a transverse passageway passing at least partially through the adjacent interlocked portions in order to form a bearing (7) in which an articulation member (10) is engaged and is held at least one end of the said transverse passageway. The mid-portion of the said articulation member (10) comprises at least one O-ring placed on the portion of the said articulation member (10) situated inside the said bearing (7) and close to its ends and in jointed contact with the wall of the said transverse passageway.

The bracelet is formed of a plurality of links (4, 5) assembled in an articulated manner by means of pins (8). Each pins passes through the interlocking parts of links in which a cylindrical passage is arranged where a pin can slide relatively freely. In order to ensure the position of the pin once the links have been assembled, a locking element (12) is arranged in a cavity (18) made in one of the links so as to partially intersect the passage in which the pin is arranged. This pin includes a groove (22) which an external part (35) of the locking element penetrates when the element is in the closed position. Pressing on the locking element then rotating it through an angle of 90° releases the external part of the pin groove such that the pin is then released. The pin locking device thus allows the links to be assembled in a reversible manner and the length of the bracelet to be varied by adding or removing at least one link.

A watch chain is disclosed. The watch chain comprises a pin groove formed at a spaced inner surface with a certain depth; a plurality of outer connection pieces which have through holes passing through the inner side of the pin groove in the direction of the back surface; a plurality of central connection pieces which have pin holes at spaced portion with the left and right sides of the same being communicated; a connection pin which passes through the pin hole of the central connection piece and is engaged at the pin groove of the outer connection piece of which both ends are connected with both sides of the central connection piece and with a screw hole being formed at both sides of the connection pin; and a screw which is engaged at the screw hole of the connection pin through the through hole, wherein the central connection piece and the outer connection piece of both sides are engaged so that a connection pin is inserted into the pin groove of the outer connection piece of one side and the pin groove of the outer connection piece of the other side through the pin hole of the central connection piece, and the screw is engaged at the screw hole of the connection pin through the through hole formed at the back surface of the outer connection piece.

A ball chain assembly may be used to form tessellated patterns of ball chains. The ball chains include a series of balls and intermediate links of a breadth less than the breadth of said balls. A chain connector of one-piece construction defines a circular array of ball-receiving sockets. Each of the sockets are sized to receive a ball of one of said chains. A ball of the chain can be inserted into one of the sockets of the chain connector where a link of the inserted ball passes through the slot extending from the socket, such that a chain can be connected to each of the sockets.

The linked bracelet, in particular for a watch, comprises a metal hinged chain passing through a series of ornamental tubular links (4) made of ceramic material, each ornamental link (4) having at least one longitudinal passage (20), in which a metal link and a hinge associated with it are housed and can rest against an inside surface (26) of the base (27) of the ornamental link in the region of the hinge, when the hinge is in a folded position. A front face (23) of each ornamental link (4) has at least one raised section (34) located in the same region of the width of the ornamental link as said inside surface (26) where the hinge or the metal link rests, this raised section being arranged to abut against the opposite front face (24) of the adjacent ornamental link when the hinge is in said folded position. This arrangement balances the vertical force (F) exerted by the chain on the base (27) of the ornamental link at the right place and thus prevents any risk of fracture by transverse bending.
