A decoration member with excellent abrasion resistance and light weight, exhibiting black-based metallic luster derived from metal is provided. A cermet containing a hard phase containing at least two or more of TiCN, TiC, TiN, and MoC 2 in a proportion of 70 mass% or more and 97 mass% or less with the remainder constituted by a binder phase and inevitable impurities is processed into a decoration member, whereby the abrasion resistance and the lightness in weight are achieved. By making the surface roughness of the decoration member equal to the mirror surface state, the decoration member whose abrasion resistance, lightness in weight, and black-based metallic luster satisfy the users can be provided.

A Brunnian link is a link formed from a closed loop doubled over itself to capture another closed loop to form a chain. Elastic bands can be utilized to form such links in a desired manner. A disclosed kit includes a template for mounting an initial band and a hook utilized for attaching additional bands to the initial bands placed on the template. The template includes pins that hold the initial band in place while additional bands are linked onto each other. The kit further includes a clip utilized to attach ends once the desired length is formed.

The present invention relates to a strand (10, 10') of a strap for a timepiece, the strand (10, 10') comprising a plurality of links (14) hinged to one another, as well as a flexible leaf (23) which is arranged such as to be connected to each one of said links (14). The links (14) comprise a central portion (15) and two lateral mountings (16, 16') arranged on either side of the central portion (15). The flexible leaf (23) according to the invention, is configured to cover at least the top or bottom side of the central portion (15) of each link (14) in order for said leaf (23) to form all or almost all of the visible top or bottom portion of the strand (10, 10').

La présente invention concerne un objet décoratif comportant une pluralité de maillons articulés les uns aux autres de façon à permettre à l'objet de prendre au moins une première configuration annulaire où les maillons présentent chacun une face orientée généralement radialement vers l'extérieur et une deuxième configuration compacte, où les maillons sont repliés les uns sur les autres de façon à présenter tous ladite face disposée d'un même côté de l'objet.
摘要:
Le bracelet articulé, notamment pour une montre, comporte une chaîne métallique à charnières traversant une série de maillons décoratifs tubulaires (4) en matériau céramique, chaque maillon décoratif (4) ayant au moins un passage longitudinal (20) dans lequel un maillon métallique et une charnière associée à celui-ci sont logés et peuvent s'appuyer contre une surface intérieure (26) du fond (27) du maillon décoratif dans la région de la charnière lorsque la charnière a une position pliée. Une face frontale (23) de chaque maillon décoratif (4) comporte au moins une bosse (34) située dans la même région de la largeur du maillon décoratif que ladite surface intérieure (26) où s'appuie la charnière ou le maillon métallique, cette bosse étant agencée pour buter contre la face frontale opposée (24) du maillon décoratif adjacent lorsque la charnière a ladite position pliée. Cet agencement équilibre au bon endroit la force verticale (F) exercée par la chaîne sur le fond (27) du maillon décoratif et évite ainsi le risque de rupture par flexion transversale.

The invention concerns a timepiece comprising a watch (10) and a band (16) fixed to its case by solely one of its ends. The band, which constitutes a spring and is shaped to be wound around the wrist, comprises several spring wires (20) and a plurality of links (22, 24) threaded on the wires. To fix the ends of the wires on the case, are provided: integral with the watch case, two horns (14) each pierced with a pair of blind holes (26) and a passage which is perpendicular to the holes and intersects them in their lower part; integral with each end of the wires, a tube (30) inserted in each of the blind holes; and a key (32) inserted in said passage and passing through notches (34) provided at that site in each of the tubes.
