Abstract: A front closure for a brassiere which is invisible in the connected state of the front flaps of the brassiere has two closure halves each with a semielliptical plate and one with an annular formation and the other with a lug snap fitted into the annular formation. Outwardly of the annular formation and the lug, the plates form sewing flanges which can be stitched through to attach fastener halves to the brassiere halves, e.g. with a zigzag stitching.

Abstract: A jewelry clasp assembly, attached to a pair of chains for displaying pearls, gemstones, gems, beads, slides, or the like, including a pair of rectangular shaped pins slidably engaged into similarly shaped receiving channels within said clasp housing and secured in place by a threaded retaining pin passing through the receiving channels and the rectangular shaped pins. The jewelry clasp so provided allows the uncomplicated addition and removal of slides, beads, and gems to and from a pair of chains, without compromising security from accidental loss.

Abstract: Inserting member 10 used for the retaining device for clothes is formed of a plastic material, and includes a base plate 11 attached to the clothes, an inserting plate 12 having, at one end of base plate 11, a vertical portion 11a extending vertically from the base plate 11, a bent portion 12b bent to a direction parallel to the base plate from the vertical portion 11a, and a parallel portion 12c extending parallel to the base plate 11 from the bent portion 12a, a convex portion 15 provided on the inserting plate 12 at a position opposing to the base plate 11, and a rib 14 provided on an outer surface of the inserting plate 12 for suppressing deflection of the inserting plate 12. Accordingly, a retaining device for clothes formed of plastic, which does not cause any chemical reaction with the chemicals used for clothes and not cause any reaction of a metal detector, which has sufficient characteristics for use and suitable for mass production can be provided.

Abstract: A bone connector including a first joint which is inserted and secured in one of cut bone pieces to be interconnected at the cut end thereof, a second joint which is inserted and secured in the other bone piece at the cut end thereof, and engaging portions provided on the first and second joints to connect the same.

Abstract: A belt strap is provided having a non-circular opening formed through one end portion thereof and a plurality of apertures formed through and spaced along the other end portion thereof. A belt fastener is provided including an adornment assembly for mounting from the outer side of the belt strap about the opening therethrough and a belt length adjusting assembly for mounting on the inner side of the belt strap about the opening formed therethrough. One of the assemblies includes a projection snugly received through the opening and the other assembly includes a threaded shank threadedly engaged in a threaded bore formed in the projection and the two assemblies define abutment surfaces between which portions of the belt strap disposed about the opening are received.

Abstract: The pairer and holder has a nylon loop which has ends thereof joined to swivel couplings. Beads of the couplings are journalled in given chambers in sections of a clasp. Other chambers in the clasp sections have, respectively, a threaded screw, with a projecting end, and a threaded bore. The projecting end of the screw is received in the bore to close the loop. The method of the invention specifies forming holes in sock pairs to receive the projecting end of the screw, and a leading end of the screw-supporting section, whereupon the screw is threaded into the bore. Hence, the holed sock pairs are held together by the pairer and holder.
