Abstract: An antenna for a wrist transmitter or receiver carried in a wrist instrument is made of a wire mesh enclosed in an elastic fabric sleeve. The antenna wire is composed of a tubular mesh of individual copper conductors which are loosely woven, twisted, or braided in such a way as to permit lateral expansion and also to assume a flat configuration. In a preferred form of the invention, the wire is woven in a manner similar to that of a coaxial cable outer shield conductor. The method of making the expansion band antenna consists of inserting an unexpanded wire mesh within a stretchable elastic fabric sleeve, expanding the mesh within the sleeve, and then flattening the sleeve and wire mesh. The wire mesh may be expanded within the sleeve by allowing a stretched sleeve to relax while holding the unexpanded mesh within it, or it may be expanded laterally within the sleeve by a mechanical or pneumatic tool.

Abstract: Extensible metal assembly, for example bracelet or ring, comprising link members (1) and connecting members (2). Each link member has at its center a cavity (3) which goes right through in the longitudinal direction of the bracelet. The side walls of said cavity have each two holes (4). The connecting member is formed by a flattened tubular envelope. In this envelope there is provided a spring (6) having four S-shaped arms. The ends of those arms form studs (5) which project by pairs on either side of the tube. The tube has a width slightly smaller than that of the cavity (3). The connecting member is arranged on the side of the cavity (3), in the same plan as the rigid element, and pushed into the cavity. Upon passing, two of the studs (5) slide against the edges (8), are retracted into the opening (7) of the tube, and expand into the holes (4), fixing the members together.

Abstract: Disclosed are expansible clasp and module constructions for connecting the free ends of a watch strap together while at the same time providing adequate expansion along the length of the strap to permit removal of the strap over the hand of the wearer without having to disconnect the free strap ends. The expansible clasp and module constructions employ one or more spring-biased sliding members disposed in a housing elongated along the strap length. In the clasp construction, the outer end of the sliding member effects releasable connection to one free strap end while one end of the housing is permanently attached to the other free strap end. The sliding member slides out of the housing against the spring bias in one direction along the strap length for expansion purposes during removal of the strap.
