Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
103 words
A latch for use with a strike and comprising a U-shaped channel member having a floor, two parallel sidewalls projecting upwardly from said floor and two flanges extending downwardly and outwardly from the upper edges of said sidewalls and terminating substantially in the plane of said floor, whereby said latch may be positioned on a planar surface with the floor and the outer edges of the flanges in contact with said surface, an elongated handle pivotally mounted to said sidewalls within said channel member, a draw bolt pivotally mounted to said elongated handle, and strike engaging means adjustably mounted on said draw bolt.
Claim 2
Dependent Claim
103 words
A latch for use with a strike and comprising a U-shaped channel member having a floor, two parallel sidewalls projecting upwardly from said floor and two flanges extending downwardly and outwardly from the upper edges of said sidewalls and terminating substantially in the plane of said floor, whereby said latch may be positioned on a planar surface with the floor and the outer edges of the flanges in contact with said surface, an elongated handle pivotally mounted to said sidewalls within said channel member, a draw bolt pivotally mounted to said elongated handle, and strike engaging means adjustably mounted on said draw bolt.
Claim 3
Dependent Claim
39 words
A latch as in claim 1 wherein said handle is in the form of an inverted U-shaped channel with the end of said channel opposite the pivot being open and adapted to receive a tool for operating said handle.
Claim 4
Dependent Claim
108 words
A latch as in claim 1 wherein the handle is adapted to be moved about its pivot to a position in which it lies entirely within the channel of said U-shaped channel member and wherein a lock bar is rotatably mounted atop one side wall of said member, said lock bar being adapted to be rotated to a position extending across said channel to prevent egress of the handle therefrom, said lock bar being located adjacent the position occupied by the pivotal connection between the draw bolt and handle when the handle lies within said channel, whereby movement of the draw bolt about its pivot will be inhibited.
Claim 5
Dependent Claim
35 words
A latch as in claim 2 further including a pair of divergent tabs on the handle extending beyond the end of the U-shaped channel member and adapted to guide a tool into the handle end.
