FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to an articulated metal band. More particularly, the invention is directed to an articulated band characterized in that it is devoid of pins and other mechanical devices for physically connecting adjacent segmental sectors or elements of the band to one another. A critical feature of the band of the invention is that it is formed of discrete metal bodies which are magnetically charged. Arrangeable, as desired, in various physical configurations, the charged metallic component elements of the band bond or adhere positively and firmly to one another, magnetically, to provide any of a selectable series of distinct and varied physical configurations or designs.

In one preferred embodiment of the invention, the articulated band assumes the physical form of a closed-loop bracelet. In each of at least two different and distinct designs or physical arrangement of component parts of embodiments of the present invention, the loop structure which constitutes the bracelet defines an uninterrupted, continuous, repetitive and endless pattern.

None of the prior art “magnetic” bracelets is believed to have the versatility of the bracelets of the present invention. None is believed to include a capability of assuming separate and distinct design configurations by a simple and rapid rearrangement of the family of magnetic physical elements employed.

DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

In accordance with the present invention, the aims and objects are achieved by providing an articulated band devoid of pins and other mechanical devices for physically connecting adjacent segmental segments, sectors, or elements to one another. Critical is the fact that the component elements of the band constitute discrete metal bodies or elements each of which is magnetically charged. In preferred embodiments of the invention the component elements of the articulated band are cylinders and discs. The component metal elements bond or adhere firmly to one another, magnetically, to provide any of a selectable series of distinct and varied physical configurations or aesthetic representations or designs. In one preferred embodiment of the invention, the band constitutes a closed-loop bracelet characterized in that it defines a continuous, uninterrupted, repetitive and endless pattern.

Referring now to the drawings, for purposes of disclosure and not in any limiting sense, a preferred embodiment of the invention is shown in FIG. 1 as comprising an articulated metal band 20 . The band 20 is devoid of hooks, pins, or other fasteners, and is in the form or configuration of a closed, endless loop 24 . The loop 24 defines a repetitive and uninterrupted continuous pattern. Referring further to FIG. 1 , the loop 24 of the band 20 is structured of metal components or elements which include cylinders 26 and discs 30 , each magnetically charged. That is, the cylinders are magnetized in a direction at right angles to the longitudinal axes thereof, and the discs 30 are magnetized in a radial direction thereof.

In the embodiment of the invention shown in FIG. 1 , the cylinders 26 and the discs 30 have the same diametric dimension, measuring about ¼ th of an inch. The cylinders 26 have an axial height 32 of about ¼ th inch, and the discs 30 have a height or thickness 34 of about {fraction (1/12)} th inch.

As shown in FIG. 1 , the cylindrical elements 26 define an essentially coplanar array, and are in contact, each cylinder 26 with the next, tangentially, thus completing the uninterrupted circle or closed loop 24 . The discs 30 are arranged in two spaced layers separated by the axial body expanse of the cylindrical elements 26 . That is, the discs 30 include an “upper” layer 38 and a “lower” layer 40 , with the cylinders 26 sandwiched therebetween (FIGS. 6 and 8 ).

In the embodiment of the invention shown in FIG. 1 and FIGS. 6 and 7 , the discs 30 are shown positioned or placed so that each overlies and bridges a pair 42 of the cylindrical elements 26 , which elements 26 contact one another tangentially. Accordingly, the discs 30 also define a lineal, continuous, tangentially-abutting array. As shown, the discs 38 constituting the upper layer, and the discs 40 constituting the lower layer of the band 20 are so disposed or arranged as to form coaxial spaced pairs 46 separated by the vertical or axial expanse of the interposed cylinders 26 . . The axis of each such pair 46 is correlated with or identifiable with a line of tangency 48 of each respective contacting pair 50 of the cylinders 26 . That is, the discs 30 are stepped or displaced arcuately (or annularly) with respect to the sandwiched cylinder elements 26 ( FIGS. 1 and 2 and 6 and 7 ). The extent of this displacement also corresponds to a radius dimension of the discs 30 or of the cylinders 26 .

It will be understood that the loop 24 defining the band 20 may be opened at any selectable juncture of contacting discs 30 or cylinders 26 by exerting a separating force manually. The resulting opened loop 24 may then be closed, for example, about the wrist of an intended wearer, so that the band 20 may be worn as a bracelet. Closure of the temporarily “severed” loop is effective to re-establish, without impairment, the original strong, but temporarily interrupted, magnetic bond forces acting between the band components.

Referring now to FIG. 2 , there is shown an articulated band 60 which is in all material respects the same as the band 20 of FIG. 1 except that it includes a connector or fastener 64 . The latter serves as a functional “insert” and constitutes a convenient mechanism by which the loop 66 formed by the band 60 is closed, and by which the band 60 may be conveniently re-opened, and re-closed, repeatedly.

As shown in FIGS. 3 , 4 and 5 , the connector 64 is bilaterally symmetrical. It includes a pair of block-like principal body portions 70 and 72 facing one another (FIG. 4 ). The height dimension of the block-like body portions 70 and 72 of the connector 64 corresponds to the combined, overall axial height of the cylinder element 36 plus the combined thicknesses of the lower and upper discs 30 (FIGS. 3 and 4 ). The body components 70 and 72 of the connector 64 are formed with inwardly-directed, outwardly-opening, curved walls 74 and 76 defining outwardly-opening recesses 82 and discs 38 constituting the upper layer, and the discs 40 constituting the lower layer of the band 20 are so disposed or arranged as to form coaxial spaced pairs 46 separated by the vertical or axial expanse of the interposed cylinders 26 . . The axis of each such pair 46 is correlated with or identifiable with a line of tangency 48 of each respective contacting pair 50 of the cylinders 26 . That is, the discs 30 are stepped or displaced arcuately (or annularly) with respect to the sandwiched cylinder elements 26 ( FIGS. 1 and 2 and 6 and 7 ). The extent of this displacement also corresponds to a radius dimension of the discs 30 or of the cylinders 26 .

Referring further to FIGS. 3 , 4 and 5 , the block-like body portions 70 and 72 of the connector 64 are integrally formed at body zones 90 and 92 thereof opposite the recessed zones 82 and 84 , with rectangular protrusions 96 and 98 . The latter are centered at the ends 102 and 104 of the body portions 70 and 72 which are opposite the curved surfaces or recesses 82 and 84 . The protrusions 96 and 98 extend laterally a distance corresponding to the radial dimension of the discs 30 (or of the cylinders 26 ), and have a vertical expanse or height corresponding to the axial dimension or height of the cylinder elements 26 . In the structure and arrangement described, each protrusion 96 and 98 is sandwiched and closely embraced at its upper and lower surfaces 108 and 110 and 112 and 114 between upper and lower discs 30 , and abuts a cylinder element 26 of the band 60 laterally (FIG. 4 ). The structure described is further illustrated in the cross-sectional view depicted in FIG. 5 .

FIGS. 6 and 7 illustrate, in a front elevational view and in a top view, respectively, physical positioning and axial orientation of the cylinders 26 and the upper and lower discs 38 and 40 (or discs 30 ) of the embodiments of the invention shown in FIGS. 1 through 5 . Fragmentary front elevational and top views provide, respectively, in FIGS. 8 and 9 , views of the physical arrangement in an alternative embodiment of the invention in which the cylinder elements 26 together with the sandwiching upper and lower discs 38 and 40 (or discs 30 ) are all arranged in a coaxial mode.
