Abstract
This invention relates to a cufflink disassemblably coupled of its two pieces, one being a decorative member and another being a keeper element, with the aid of a spring clip. The above assembling and disassembling are made quite easily and quickly by manual one touch fingering at a desired time, and once attached through button holes of the shirt's cuff which may be either one of double type or convertible type it is designed not to slip-off from the cuff, even when the cufflink brushes against a person and/or an object.
Claims7
In a cufflink which is disassemblably assembled of two sub-assembly elements comprising a decorative head element and a link shank element,
- the improvement wherein:
- (a) the decorative head element includes:
- (i) a casing shell having a rear cover plate centrally provided with a through hole and an inside face presented towards the interior of the casing shell;
- (ii) a spectacles frame-shaped spring clip having a pair of laterally spaced, generally U-shaped legs having respective free end portions nearest one another and having respective opposite ends joined by a rim;
- said rim, in the vicinity of said free end portions having an arcuate bridge portion;
- all of said spring clip but for said bridge portion lying generally in a common plane, and said bridge portion extending at an acute angle which intersects said common plane where said bridge portion meets the remainder of said rim;
- (iii) said rear cover plate including limited gap bracket means mounting said spring clip by the jamming of said bridge portion into a limited gap provided by said bracket means, this limited gap being able to receive said bridge portion only when said rim is resiliently torsionally stressed by an amount sufficient to cause said bridge portion to lie substantially in said common plane, whereby said spring clip is resiliently loaded against said inside face of said rear cover plate;
- (iv) said spring clip free end portions being juxtaposed with said hole for normally blanking-off two diametrically-opposed perimetrical segments of the hole;
- and
- (b) the link shank element includes:
- (i) a shank having a head end and a keeper end;
- (ii) a keeper secured to the keeper end of the shank;
- (iii) the head end having a convexly curved head provided with a diametrically opposed pair of grooves which extend angularly of the shank,
- so that when the head of the link shank element is thrust into the hole in the rear cover plate of the decorative head element, the head first deflects the spring clip legs away from the rear cover plate and their free end portions laterally away from one another, until the free end portions snap into the respective grooves as the torsional stresses in said rim force the spring clip legs back against said inside face of said rear cover plate.
