Abstract
Abstract A hasp cooperable wit a latching member of a latching device employs a convexly shaped spring member to automatically eject or separate the hasp from the latching device when the latching member is moved from latched to unlatched position. The spring member is formed with means for connecting it to the portion of the hasp adapted to receive the latching member in its latched position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
95 words
A hasp cooperable with a latching member of a latching device, the hasp comprising a body member having a substantially U-shaped portion projecting from its underside to provide an opening adapted to receive a latching member in its latched position, and a convexly shaped spring member connected to the substantially U-shaped portion, said spring member having an aperture through which the substantially U-shaped portion is extended, the ends of the spring member being free to slide on the adjacent surface of the body member when the spring member is deformed from its normally convex shape.
Claim 2
Dependent Claim
95 words
A hasp cooperable with a latching member of a latching device, the hasp comprising a body member having a substantially U-shaped portion projecting from its underside to provide an opening adapted to receive a latching member in its latched position, and a convexly shaped spring member connected to the substantially U-shaped portion, said spring member having an aperture through which the substantially U-shaped portion is extended, the ends of the spring member being free to slide on the adjacent surface of the body member when the spring member is deformed from its normally convex shape.
Claim 3
Dependent Claim
26 words
A hasp according to claim 1, wherein the convexly shaped spring member is provided with integral means connecting the spring member to the substantially U-shaped portion.
Claim 4
Dependent Claim
80 words
A hasp according to claim 1, wherein the aperture in the convexly shaped spring member is defined by a pair of longitudinally extending, opposite sides and longitudinally spaced ends, the sides being provided with opposed, inwardly projecting tabs substantially midway of the length of the aperture, the distance between the tabs being slightly less than the thickness of the base of the substantially U-shaped portion and being sprung over the base to connect the spring to the substantially U-shaped portion.
Claim 5
Dependent Claim
27 words
A hasp according to claim 3, wherein the sides of the base are beveled to facilitate the connection of the spring member to the substantially U-shaped portion.
Claim 6
Dependent Claim
23 words
A hasp according to claim 1, including integral means provided by the body member for the connection of the hasp to a support.
Claim 7
Dependent Claim
57 words
A hasp according to claim 1, wherein the body member is provided with a recess on the underside thereof adjacent the substantially U-shaped portion, said recess being adapted to receive supporting means for the hasp, and integral, spaced connecting studs extending from the underside of the body member for connection of the hasp to the supporting means.
Claim 8
Dependent Claim
57 words
A hasp according to claim 3, wherein the body member is provided with a recess on the underside thereof adjacent the substantially U-shaped portion, said recess being adapted to receive supporting means for the hasp, and integral, spaced connecting studs extending from the underside of the body member for connection of the hasp to the supportinG means.
Claim 9
Dependent Claim
33 words
A hasp according to claim 3, wherein the longitudinally spaced ends of the concavely shaped spring member are adjacent the juncture with the body member of the arms of the substantially U-shaped portion.
Claim 10
Dependent Claim
33 words
A hasp according to claim 7, wherein the longitudinally spaced ends of the concavely shaped spring member are adjacent the juncture with the body member of the arms of the substantially U-shaped portion.
