Abstract
Abstract A locking apparatus secures a portable hand held object such as a tape measure to a support strip such as the belt of a wearer, some other portion of a wearer's clothing, or a wearer's tool pouch. The apparatus is constructed to provide full encirclement of the belt or other support, eliminating the danger of inadvertent dislodgement while permitting one-hand release. The apparatus consists of a plate bent over at one end to form a lip and at the other to form an angled extension, and mounted in a spring-biased manner to the lateral face of the object such that the lip abuts the lateral face while the angled extension extends over the top, leaving the gap between the plate and the lateral face to receive the belt and a further gap between the angled extension and the top surface of the object to permit manipulation by compressing with the heel of one's hand while one's fingers grip the bottom surface of the object.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
37 words
Locking apparatus for releasably securing an object to a support strip, said object having exterior surfaces including a top surface and a lateral face and a spring clip secured to said lateral face, said locking apparatus comprising:
Claim 2
Dependent Claim
37 words
Locking apparatus for releasably securing an object to a support strip, said object having exterior surfaces including a top surface and a lateral face and a spring clip secured to said lateral face, said locking apparatus comprising:
Claim 3
Dependent Claim
113 words
a plate having first and second opposing edges; a lip protruding from one side of said plate along said first edge; an extension along said second edge of said plate, angled with respect thereto toward the same side of said plate as said lip and extending further from said plate than said lip; and means for affixing said plate to said spring clip with said extension extending over said top surface at a gap therefrom and said lip abutting said lateral face thereby holding said spring clip open, whereby pressure on said extension toward said top surface causes separation of said lip from said lateral face to permit insertion of said support strip.
Claim 4
Dependent Claim
113 words
a plate having first and second opposing edges; a lip protruding from one side of said plate along said first edge; an extension along said second edge of said plate, angled with respect thereto toward the same side of said plate as said lip and extending further from said plate than said lip; and means for affixing said plate to said spring clip with said extension extending over said top surface at a gap therefrom and said lip abutting said lateral face thereby holding said spring clip open, whereby pressure on said extension toward said top surface causes separation of said lip from said lateral face to permit insertion of said support strip.
Claim 5
Dependent Claim
23 words
Locking apparatus in accordance with claim 1 in which said affixing means comprises a sleeve on said plate for receiving said spring clip.
Claim 6
Dependent Claim
38 words
Locking apparatus in accordance with claim 1 in which said spring clip is comprised of a tongue of resilient material and said affixing means is comprised of means defining a slot on said plate for receiving said tongue.
Claim 7
Dependent Claim
34 words
Locking apparatus in accordance with claim 1 in which said spring clip is comprised of a tongue of resilient material and said affixing means is comprised of rivets securing said tongue to said plate.
Claim 8
Dependent Claim
56 words
Locking apparatus in accordance with claim 1 in which said spring clip is comprised of a tongue of resilient material and said affixing means is comprised of screws to pass through clearance holes in one of said plate and said tongue and to mate with threaded holes in the other of said plate and said tongue.
Claim 9
Dependent Claim
40 words
Locking apparatus in accordance with claim 1 in which said spring clip is comprised of a tongue of resilient material terminating in an outwardly curved tip, and said plate further comprises a slot permitting passage of said outwardly curved tip.

Locking apparatus in accordance with claim 1 in which said spring clip is comprised of a strip of resilient material curved into an inverted U having first and second sides, with a mounting hole in said first side for screw attachment to said lateral face of said object and an access hole in said second side to permit insertion and removal of a screw through said mounting hole, and said locking apparatus further comprises a hole in said plate positioned to fall into alignment with said access hole and said mounting hole when said plate is mounted to said object.
Claim 11
Dependent Claim
28 words
Locking apparatus in accordance with claim 1 in which said affixing means comprises studs protruding from said plate and keyways in said spring clip to receive said studs.
Claim 12
Dependent Claim
31 words
Locking apparatus in accordance with claim 1 in which said lip has a surface facing away from said plate, said surface being at an acute angle with respect to said plate.
Claim 13
Dependent Claim
142 words
Locking apparatus for releasably securing a tape measure housing to a belt, said tape measure housing having a top surface and a lateral face and a spring clip secured to said lateral face, said locking apparatus comprising: a plate having top and bottom edges; a lip protruding from one side of said plate along said bottom edge; an extension along said top edge of said plate, angled with respect thereto toward the same side of said plate as said lip and extending further from said plate than said lip; and means for securing said plate to said spring clip with said extension extending over said top surface at a gap therefrom and said lip abutting said lateral face, whereby pressure on said extension toward said top surface causes separation of said lip from said lateral surface to permit insertion of a belt.
Claim 14
Dependent Claim
142 words
Locking apparatus for releasably securing a tape measure housing to a belt, said tape measure housing having a top surface and a lateral face and a spring clip secured to said lateral face, said locking apparatus comprising: a plate having top and bottom edges; a lip protruding from one side of said plate along said bottom edge; an extension along said top edge of said plate, angled with respect thereto toward the same side of said plate as said lip and extending further from said plate than said lip; and means for securing said plate to said spring clip with said extension extending over said top surface at a gap therefrom and said lip abutting said lateral face, whereby pressure on said extension toward said top surface causes separation of said lip from said lateral surface to permit insertion of a belt.
Claim 15
Dependent Claim
158 words
A portable object attachable to a belt, comprising: a housing having an external contour including a top surface and a lateral face; a plate having first and second sides and first and second opposing edges; a lip on said first side of said plate along said first edge; an extension protruding from said first side of said plate along said second edge, angled with respect to said plate and exceeding said lip; a resilient tongue on said first side of said plate, offset and substantially parallel thereto to permit passage of a belt between said resilient tongue and said plate; and means for affixing said resilient tongue to said lateral face of said object, urging said lip against said lateral face with said extension extending over said top surface, whereby pressing said extension toward said top surface pivots said lip away from said lateral face to permit insertion of said belt between said resilient tongue and said plate.
