Abstract

Abstract A buckle includes an open rectangular frame having a passage lying in the plane of the frame, together with a locking washer slidably disposed in the passage. Means are provided, in the form of complemental construction on the frame and washer, preventing the locking washer from falling out of the frame at least in one direction. One strap end can be secured to one transverse portion of the frame, while another strap end can be directed through the opening in the frame, around one side of the locking washer, and back through the same opening. The other side of the locking washer can extend through the other side of the frame.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 174 words
A buckle comprising: (a) a generally annular frame including a pair of opposite side members and a pair of opposite transverse members jointly defining a single first opening bounded thereby, there being a frame passage in the plane of the frame extending through only one of said transverse members and said opening in parallel with the length of said side members; and (b) a locking washer slidably disposed in said passage, said washer having a cross-member and a tongue-shaped extension defining opposite portions of said washer with a second opening therebetween, said cross-member dividing said single first opening into a pair of band-receptive passages therethrough, said cross-member and said second opening having a combined extent less than that of the length of said side members, said tongue-shaped extension being extendable through said one transverse member, said locking washer having a wedge-shaped projection on said extension enabling said one transverse member to be temporarily deformed for receiving said projection into said first opening and for thereafter precluding removal of said locking washer from said frame.
Claim 2
Dependent Claim 174 words
A buckle comprising: (a) a generally annular frame including a pair of opposite side members and a pair of opposite transverse members jointly defining a single first opening bounded thereby, there being a frame passage in the plane of the frame extending through only one of said transverse members and said opening in parallel with the length of said side members; and (b) a locking washer slidably disposed in said passage, said washer having a cross-member and a tongue-shaped extension defining opposite portions of said washer with a second opening therebetween, said cross-member dividing said single first opening into a pair of band-receptive passages therethrough, said cross-member and said second opening having a combined extent less than that of the length of said side members, said tongue-shaped extension being extendable through said one transverse member, said locking washer having a wedge-shaped projection on said extension enabling said one transverse member to be temporarily deformed for receiving said projection into said first opening and for thereafter precluding removal of said locking washer from said frame.
Claim 3
Dependent Claim 172 words
A buckle comprising: (a) a generally annular frame including a pair of opposite side members and a pair of opposite transverse members jointly defining a single first opening bounded thereby, there being a frame passage in the plane of the frame extending through at least one of said transverse members and said opening in parallel with the length of said side members; and (b) a locking washer slidably disposed in said passage, said washer having a cross-member and a tongue-shaped extension defining opposite portions of said washer with a second opening therebetween, said cross-member dividing said single first opening into a pair of band-receptive passages therethrough, said cross-member and said second opening having a combined extent less than that of the length of said side members, said tongue-shaped extension being extendable through said one transverse member, said tongue-shaped extension and a portion of said frame passage lying in said one transverse member respectively having lesser thicknesses in a direction normal to that of the sliding of the locking washer, than said cross-member.
Claim 4
Dependent Claim 172 words
A buckle comprising: (a) a generally annular frame including a pair of opposite side members and a pair of opposite transverse members jointly defining a single first opening bounded thereby, there being a frame passage in the plane of the frame extending through at least one of said transverse members and said opening in parallel with the length of said side members; and (b) a locking washer slidably disposed in said passage, said washer having a cross-member and a tongue-shaped extension defining opposite portions of said washer with a second opening therebetween, said cross-member dividing said single first opening into a pair of band-receptive passages therethrough, said cross-member and said second opening having a combined extent less than that of the length of said side members, said tongue-shaped extension being extendable through said one transverse member, said tongue-shaped extension and a portion of said frame passage lying in said one transverse member respectively having lesser thicknesses in a direction normal to that of the sliding of the locking washer, than said cross-member.
