Abstract
Abstract A hinged cord locking device is adapted to be clamped onto the support bar of an article to be locked such as one of the frame bars of a bicycle. The cord may be withdrawn from a spring retractable reel, wrapped around a stationary object and the locking bolt on free end of the cord locked in a locking channel in the hinged body portion of the device to thereby affix the article to the object. The hinged body portions rotatably support the two piece cable reel which is positively interlocked with the body portions to prevent removal thereof from the support bar. The locking channel is defined by the two body portions such that insertion of the locking bolt into the channel locks the cord to the body portions, the hinged body portions together and the cable reel to the body portions. When so locked, the locking device cannot be removed by opening or sliding axially off a support bar.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
172 words
A flexible cord locking device adapted to be clamped on a bar comprising co-operating first and second body portions having hinge means for pivotally interconnecting said body portions along one side thereof, said body portions co-operating to define throughout the length thereof a recess through which a support bar upon which the locking device is to be mounted is received, means for securing said body portions in clamped relationship including locking portions on said first and second body portions which co-operate when the body portions are brought together to define a locking channel, a cord reel having separable first and second sections supported on said body portions for rotation relative thereto, a flexible cord secured at one end to said reel and having a lock bolt connected to the free end thereof, releaseable locking means associated with said locking channel and operable to engage and lock said locking bolt when inserted into said locking channel to thereby secure the flexible cord to said body portions and prevent opening of said body portions.
Claim 2
Dependent Claim
172 words
A flexible cord locking device adapted to be clamped on a bar comprising co-operating first and second body portions having hinge means for pivotally interconnecting said body portions along one side thereof, said body portions co-operating to define throughout the length thereof a recess through which a support bar upon which the locking device is to be mounted is received, means for securing said body portions in clamped relationship including locking portions on said first and second body portions which co-operate when the body portions are brought together to define a locking channel, a cord reel having separable first and second sections supported on said body portions for rotation relative thereto, a flexible cord secured at one end to said reel and having a lock bolt connected to the free end thereof, releaseable locking means associated with said locking channel and operable to engage and lock said locking bolt when inserted into said locking channel to thereby secure the flexible cord to said body portions and prevent opening of said body portions.
Claim 3
Dependent Claim
32 words
A flexible cord locking device as defined in claim 1 further including spring means operable to bias said reel to rotate in one direction causing the cord to wrap onto the reel.
Claim 4
Dependent Claim
36 words
A flexible cord locking device as defined in claim 2, wherein said spring means comprises a negator tape spring having one end secured to a spring spool and the other end fixed to said cord reel.
Claim 5
Dependent Claim
52 words
A flexible cord locking device as defined in claim 3, wherein said spring means further includes a housing for said spring spool, means pivotally supporting said housing on said body portions to permit said housing to move out of interference with said body portion as they are pivoted to their open position.
Claim 6
Dependent Claim
38 words
A flexible cord locking device as defined in claim 1 further including means providing a rotatable interlocking connection between said cord reel and said body portion to prevent axial separation of said cord reel from said body portions.
Claim 7
Dependent Claim
34 words
A flexible cord locking device as defined in claim 5, wherein said rotatable interlocking connection comprises a circumferential collar on said cable reel mounted for rotation in a circular groove in said body portions.
Claim 8
Dependent Claim
57 words
A flexible cord locking device as defined in claim 1, wherein said body portions comprise first and second axially spaced hubs, said first hub having said locking portions and an annular groove, and said cable reel having a flange rotatably keyed in said groove to prevent said reel from being removed axially relative to said first hub.
Claim 9
Dependent Claim
38 words
A flexible cord locking device as defined in claim 7 further including a cylindrical sleeve fixedly supported on said first and second hubs, an elongated opening in a portion of said sleeve through which said flexible cord passes.
Claim 10
Dependent Claim
119 words
A flexible cord locking device, adapted to be secured to a bar comprising first and second hubs adapted to be mounted on a support bar at axially spaced locations, bearing means on said hubs, a cord reel having first and second bearing surfaces engageable with said bearing means to provide for rotation of said reel relative to said hubs, means associated with said first bearing surface and said bearing means for interlocking said reel and said first hub to prevent relative axial movement therebetween, a flexible cord secured to said reel and having a locking bolt on the free end, and means providing a locking channel on said first hub into which said locking bolt is received and secured.
Claim 11
Dependent Claim
119 words
A flexible cord locking device, adapted to be secured to a bar comprising first and second hubs adapted to be mounted on a support bar at axially spaced locations, bearing means on said hubs, a cord reel having first and second bearing surfaces engageable with said bearing means to provide for rotation of said reel relative to said hubs, means associated with said first bearing surface and said bearing means for interlocking said reel and said first hub to prevent relative axial movement therebetween, a flexible cord secured to said reel and having a locking bolt on the free end, and means providing a locking channel on said first hub into which said locking bolt is received and secured.
Claim 12
Dependent Claim
29 words
A flexible cord locking device as defined in claim 9 further comprising spring means operatively connected to said cord reel to bias said reel for rotation in one direction.
Claim 13
Dependent Claim
51 words
A flexible cord locking device as defined in claim 10, wherein said first hub provides an arcuate recess defining said bearing means and said spring means includes a spring tape secured at one end to a spool and the other end extending through said recess and secured to said cord reel.
Claim 14
Dependent Claim
78 words
A flexible cord locking device as defined in claim 9, wherein said first and second hubs and said cord reel are each formed of two parts, hinge means interconnecting each of said parts and said means providing a locking channel includes cooperating portions on each part of said first hub such that insertion of said locking bolt therein interlocks said hinged parts of said first hub and prevents removal thereof from or by sliding along the support bar.
