Abstract
A plastic watchband made of individual links, having greater variety in design and secureness of fit is provided. The plastic watch band is joined of a plurality of separate links, each link having an engagement projection on one platform for engaging an enjoining link through an engagement opening on another platform of an adjacent link. A flexible intermediate member is provided between the platforms. The intermediate region is angled relative to the platforms so that the engagement opening is offset relative to the engagement projection.
Claims11
A watchband formed of a plastic material, comprising a plurality of interlocking band elements, each element formed with at least one engaging projection and at least one receiving opening, the engaging projection adapted to be operatively engaged by the receiving opening in an adjacent element to retain the projection therein for forming the watchband, each band element including a first substantially planar platform and a second substantially planar platform, the engaging projection formed on the first platform, and the receiving opening formed on the second platform, the platform being joined by an intermediate portion wherein the intermediate portion is flexible;
- and wherein the intermediate region is formed at an angle relative to the first and second platforms for forming a watchband of relatively uniform width.
An interlocking element for forming a bracelet of a plastic material, comprising:
- a first substantially planar platform and a second substantially planar platform, the first platform and the second platform being joined by a flexible intermediate member;
- at least one receiving opening extending through the second platform;
- at least one engaging projection integrally formed with the first platform and extending therefrom, the projection having a base and a top, the top having a diameter greater than the diameter of the base for forming a lip, the projection being adapted to be operatively engaged by the receiving opening in an adjacent element to retain the projection therein for forming the bracelet;
- the intermediate member being at an angle relative to the first platform and the second platform so that the plane of the first platform is offset relative to the plane of the second platform;
- the upper portion of the receiving opening having a diameter greater than the diameter of the top of the engaging projection, the lower portion of the opening having a diameter greater than the diameter of the top of the projection and the intermediate region of the opening having a diameter less than the top of the projection for forming a shoulder at the intersection of the upper and intermediate portions so that the lip of the projection engages the shoulder of the projection when the projection is inserted into the opening thereby selectively engaging the adjacent element having the projection.
A bracelet formed of a plastic material comprising:
- a plurality of interlocking bracelet elements each element including;
- a first substantially planar platform and a second substantially planar platform, the first platform and the second platform being joined by a flexible intermediate member;
- at least one receiving opening extending through the second platform;
- at least one engaging projection integrally formed with the first platform and extending therefrom, the projection having a base and a top, the top having a diameter greater than the diameter of the base for forming a lip, the projection is adapted to be operatively engaged by the receiving opening in an adjacent element to retain the projection therein for forming the bracelet;
- the intermediate member being at an angle relative to the first platform and the second platform so that the plane of the first platform is offset relative to the plane of the second platform for providing a substantially uniform curved surface of adjacent elements;
- and
- the upper portion of the receiving opening has a diameter greater than the diameter of the top of the engaging projection, the lower portion of the opening having a diameter greater than the diameter of the top of the projection and the intermediate region of the opening has a diameter less than the top of the projection for forming a shoulder at the intersection of the upper and intermediate portions so that the lip of the projection engages the shoulder of the projection when the projection is inserted into the opening thereby selectively engaging the adjacent element having the projection.
A watchband formed of a plastic material, comprising a plurality of interlocking band elements, each element with at least one engaging projection and at least one opening, the engaging projection adapted to be operatively engaged by the receiving opening in an adjacent element to retain the projection therein for forming the watchband and a watchcase formed with an engaging projection adapted to be operatively engaged by the receiving opening in an adjacent element.
A watchband formed of a plastic material, comprising a plurality of interlocking band elements, each element formed with at least one engaging projection and at least one receiving opening, the engaging projection adapted to be operatively engaged by the receiving opening in an adjacent element to retain the projection therein for forming the watchband;
- and
- a selectively openable and closeable clasp assembly, the clasp assembly including a male member operatively engageable with the last element on one side of the watchband and a cooperating female member operatively engagable with the last element on the opposite side of the watchband;
- and
- wherein the male member includes an upwardly projecting hook having a downwardly facing tip for engaging the female member and the female member is formed with an opening for receiving the hook and an adjacent notch for engaging the downwardly facing tip of the hook to secure the clasp in a closed position.
