Abstract
Abstract A clasp for a pair of wristbands on a digital watch having a pager with a radio frequency receiver such that the wristbands comprise an antenna that has its circuit completed and closed into a loop antenna when a user snaps the wristbands together with the clasp. The clasp has a catch shaft welded or soldered to a clasp body such that electrical contact between the antenna in the wristbands is thereby improved.

Claim 1
Independent Claim
361 words
A clasp device for electrically connecting antennae/straps use on portable information transfer devices having a case and combination antenna and user support straps extending outward from opposite sides of the case, each antenna/strap having a soft pliable material formed over a thin conductive material used as a portion of a loop antenna to be completed by the clasp, the clasp comprising: a clasp base electrically connected and mechanically fastened to a first antenna/strap, comprising: a clasp body having two or more protrusions configured to interlock with a plurality of wells formed on one surface of the first antenna/strap and make electrical contact with the conductive material inside the first antenna/strap; a keeper plate positioned to press against the first strap from a side opposite the protrusions and retain the first antenna/strap in position against the protrusions; an antenna/strap anchor claw rotatably mounted on an anchor claw shaft secured to the clasp body, being freely rotated between at least one open position away from the keeper plate and a closed position in pressure contact with the keeper plate so as to press the keeper plate against the first antenna/strap; and a catch shaft immovably secured to the clasp body, spaced apart from and parallel to the anchor claw shaft so as to not interfere with rotation of the anchor claw; a hook unit that interlocks with and fastens in disengageable fashion to the clasp base and electrically connects and mechanically fastens to the second antenna/strap, comprising: an integrated hook body having a first hook extending out and removably hooking around the catch shaft, said body being secured to an end of the second antenna/strap and maintaining electrical contact therewith, a cover hinge shaft mounted on the hook body adjacent a base of the first hook; and a closing cover rotatably attached to the cover hinge shaft such that it rotates freely about the hinge shaft and is positioned over the first hook, said cover having a second hook extending downward from one surface that removably interlocks with a closing cover anchor shaft disposed on the clasp body, and makes the first hook non-removable when the hook unit interlocks with the clasp body.

Claim 3
Dependent Claim
64 words
The clasp of claim 1 wherein said integrated hook body comprises a metallic plate having two fastening ears extending from opposite edges which are bent over outer edges of said second antenna/strap and secured thereto using electrically conductive fasteners extending into contact with the conductive material within, and a hook tongue extending toward the catch shaft over the cover hinge and under the cover.
Claim 4
Dependent Claim
39 words
The clasp of claim 2 wherein said electrically conductive fasteners comprise a pair of metallic screws positioned in threaded apertures that extend through the fastening ears, whereby secure attachment to the second antenna/strap is obtained with a removable body.
Claim 5
Dependent Claim
31 words
The clasp of claim 1 wherein said second hook on the closing cover interlocks with the cover anchor shaft so as to make the hook body non-movable about the catch shaft.
Claim 6
Dependent Claim
16 words
The clasp of claim 1 wherein said closing cover anchor shaft comprises the anchor claw shaft.
Claim 7
Dependent Claim
46 words
The clasp of claim 4 wherein said anchor claw has a surface positioned adjacent said catch shaft when in a closed position which inhibits removal of the first hook and a slot in that surface for insertion of the hook during engagement with the catch shaft.
