Abstract
Abstract The adjustable tape measure clip includes a strip of spring steel folded over to form a primary spring with opposing leaves, the inner leaf being adapted for attachment to the case of the tape measure. The inner leaf includes a secondary spring for adjusting the spring force of the primary spring on the leaves of the clip. A mounting screw, which mounts the spring clip onto the case of the tape measure, also engages the secondary spring on the inner leaf to adjust the secondary spring force on the primary spring. As the screw is rotated, the secondary spring varies the primary spring force and thus adjusts the free clip width between the leaves to either increase or decrease the gripping pressure of the clip on the user's apparel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
118 words
A clip for mounting a tool onto the user's apparel, comprising: a spring of a continuous length of metal including a first length for mounting said spring to the tool, a third length for gripping the user's apparel, and a second length between said first and third lengths for elastically attaching said first length to said third length; connecting said first and third lengths; said first length being disposed opposite said third length by said second length; said third length in contact with said first length and pressing upon said first length with a contact pressure; and said first length further having an excitation means for applying a force to said second length to adjust said contact pressure.
Claim 2
Dependent Claim
118 words
A clip for mounting a tool onto the user's apparel, comprising: a spring of a continuous length of metal including a first length for mounting said spring to the tool, a third length for gripping the user's apparel, and a second length between said first and third lengths for elastically attaching said first length to said third length; connecting said first and third lengths; said first length being disposed opposite said third length by said second length; said third length in contact with said first length and pressing upon said first length with a contact pressure; and said first length further having an excitation means for applying a force to said second length to adjust said contact pressure.
Claim 3
Dependent Claim
17 words
The clip of claim 1, wherein said excitation means is a half-elliptical spring in said first length.
Claim 4
Dependent Claim
32 words
The clip of claim 1, wherein said excitation means includes adjustment means adapted for connection to the tool for applying a predetermined force on said excitation means to adjust said contact pressure.
Claim 5
Dependent Claim
25 words
The clip of claim 1, wherein said excitation means is a contoured portion of said first length to slidingly engage a protrusion from the tool.
Claim 6
Dependent Claim
19 words
The clip of claim 1, wherein said first length is contoured to slidingly engage a recess in the tool.
Claim 7
Dependent Claim
104 words
A clip for attaching a tool to a wearer's apparel, comprising: a generally U-shaped spring including a mounting end and a gripping end; said mounting end being attached to the tool; said gripping end being in contact with the tool and having a mounting slot therein; a sliding adjustment plate disposed adjacent the terminus of said gripping end; an adjustment screw extending through said slot and attached to said plate whereby said screw is slidingly received within said mounting slot; and said plate being adjusted between said bearing end and the tool for modifying the force under which said gripping end contacts the tool.
Claim 8
Dependent Claim
104 words
A clip for attaching a tool to a wearer's apparel, comprising: a generally U-shaped spring including a mounting end and a gripping end; said mounting end being attached to the tool; said gripping end being in contact with the tool and having a mounting slot therein; a sliding adjustment plate disposed adjacent the terminus of said gripping end; an adjustment screw extending through said slot and attached to said plate whereby said screw is slidingly received within said mounting slot; and said plate being adjusted between said bearing end and the tool for modifying the force under which said gripping end contacts the tool.
