Abstract
Abstract A strain relief device for supporting a cable used with a communications headset of the type worn on a user''s ear. The device provides freedom of movement and relief from strain resulting from the weight of the cable. A transversely bored plunger is slidably mounted in a transversely bored housing with slots provided through these two parts for receiving the cable. The plunger is yieldably urged in a direction to releasably grip the cable in the desired position when the housing is clipped to the user''s wearing apparel. The device facilitates rapid adjustment of cable position by either sliding the cable relative to the housing, or pivoting the housing with respect to the clip. Means are provided to prevent unintended separation of the cable from the device during this adjustment.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
A device for adjustably supporting a cable on the wearing apparel of a user, the device including the combination of: a housing having a cavity defining a closed end and an open end, the housing being formed with a transverse bore for receiving a length of the cable and a slot through a side of the housing extending into the bore on a side thereof remote from the closed end; a plunger slidably mounted in the housing cavity for movement between a cable gripping position and a cable releasing position, the plunger being formed with a transverse bore for receiving the length of cable and a slot on a side of the plunger extending to the plunger bore on a side thereof remote from the housing open end; clip means secured to the housing to releasably engage a portion of said wearing apparel; and, means yieldably urging the plunger to its gripping position to releasably lock the cable between the plunger and housing bores.
Claim 2
Independent Claim
164 words
A device for adjustably supporting a cable on the wearing apparel of a user, the device including the combination of: a housing having a cavity defining a closed end and an open end, the housing being formed with a transverse bore for receiving a length of the cable and a slot through a side of the housing extending into the bore on a side thereof remote from the closed end; a plunger slidably mounted in the housing cavity for movement between a cable gripping position and a cable releasing position, the plunger being formed with a transverse bore for receiving the length of cable and a slot on a side of the plunger extending to the plunger bore on a side thereof remote from the housing open end; clip means secured to the housing to releasably engage a portion of said wearing apparel; and, means yieldably urging the plunger to its gripping position to releasably lock the cable between the plunger and housing bores.
Claim 3
Dependent Claim
39 words
The invention of claim 1 and further characterized in that said clip means is rotatably mounted with respect to said housing for selective adjustment of the angular position of the length of cable with respect to the clip means.
Claim 4
Dependent Claim
48 words
The invention of claim 1 and further including means pivotally mounting said housing on the clip means, and means yieldably holding said housing in gripping relationship on the clip means to permit selective pivotal adjustment of the housing and length of cable with respect to the clip means.
Claim 5
Dependent Claim
52 words
The invention of claim 3 and further characterized in that said housing includes a stud projecting outwardly on a side substantially opposite of said housing slot, said clip means includes an opening mounted over said stud, and said yieldable means includes a locking ring retaining said stud within the clip means opening.
Claim 6
Dependent Claim
48 words
The invention of claim 1 and further including stop means to limit inward displacement of said plunger with respect to said housing to a position where the plunger slot is moved in relation to the housing slot precluding unintended separation of the cable from the cable releasing position.
Claim 7
Dependent Claim
51 words
The invention of claim 5 and further characterized in that said stop means includes a circumferential shoulder on the distal end of said plunger, said shoulder axially spaced from the housing open end in said cable gripping position of the plunger, and engaging said open end in said cable releasing position.
