Abstract
Abstract A buckle device for a safety strap for use with skis. The buckle device is comprised of a housing having a cavity therein and a slotlike opening providing communication to the cavity. The upper wall of the cavity is defined by a resilient tab having a push button or the like thereon to facilitate a flexing of the tab downwardly into the cavity. A catch part having generally the thickness corresponding to the width of the slotlike opening in the housing is adapted to be slid through the slotlike opening in the housing so that the free end of the catch part becomes positioned within the cavity in the housing. The catch part has a flexible tab thereon forming a barb or hook which, upon entry into the cavity, will engage a projection in the cavity to prevent a removal of the catch part from the cavity. A depressing of the push button will effect an engagement between the upper wall of the cavity and the barb or hook to locate the barb or hook in alignment with the slotlike opening. Once this alignment has occurred, the catch part can be pulled from the cavity.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
386 words
A buckle for use with a safety strap to effect a securement of a skier to a ski, comprising: a first buckle part having means defining a housing thereon, said housing having spaced side walls and spaced end walls, the spacing between said walls defining a cavity therebetween, means defining a passageway in one of said end walls extending from the exterior of said housing into said cavity, stationary lip means adjacent one side of said passageway and facing inwardly of said cavity, at least one of said side walls adjacent said lip means being defined by a first resiliently flexible tab formed on said housing and anchored thereon adjacent said end wall remote from said end wall having said passageway therein, said first tab being pivotal about the anchor point from a normal position spaced from said lip means into said cavity so that the free end thereof is movable into said cavity past said lip means, the resiliency of said first tab effecting a return thereof to said normal position; and a second buckle part having a flat annular frame with a central opening therein and a second resiliently flexible tab extending into said opening from one edge of said annular frame, said second tab being formed to normally project out of the plane of said annular frame at the free end thereof and being flexible out of the normal position into the plane of said annular frame, said second buckle part being received in said passageway and said cavity with said one edge of said frame being positioned adjacent said one end wall of said housing and said free end of said second tab projecting toward said one side wall of said housing and said free end of said first tab past said lip means, said free end of said second tab engaging said lip means to prevent withdrawal of said second buckle part from said cavity, said first tab being resiliently flexed into said cavity and into engagement with said second tab to effect a movement of said second tab out of said normal position into said plane of said annular frame to position said second tab in alignment with said passageway and out of alignment with said lip means for removal of said second buckle part from said first buckle part.
Claim 2
Dependent Claim
386 words
A buckle for use with a safety strap to effect a securement of a skier to a ski, comprising: a first buckle part having means defining a housing thereon, said housing having spaced side walls and spaced end walls, the spacing between said walls defining a cavity therebetween, means defining a passageway in one of said end walls extending from the exterior of said housing into said cavity, stationary lip means adjacent one side of said passageway and facing inwardly of said cavity, at least one of said side walls adjacent said lip means being defined by a first resiliently flexible tab formed on said housing and anchored thereon adjacent said end wall remote from said end wall having said passageway therein, said first tab being pivotal about the anchor point from a normal position spaced from said lip means into said cavity so that the free end thereof is movable into said cavity past said lip means, the resiliency of said first tab effecting a return thereof to said normal position; and a second buckle part having a flat annular frame with a central opening therein and a second resiliently flexible tab extending into said opening from one edge of said annular frame, said second tab being formed to normally project out of the plane of said annular frame at the free end thereof and being flexible out of the normal position into the plane of said annular frame, said second buckle part being received in said passageway and said cavity with said one edge of said frame being positioned adjacent said one end wall of said housing and said free end of said second tab projecting toward said one side wall of said housing and said free end of said first tab past said lip means, said free end of said second tab engaging said lip means to prevent withdrawal of said second buckle part from said cavity, said first tab being resiliently flexed into said cavity and into engagement with said second tab to effect a movement of said second tab out of said normal position into said plane of said annular frame to position said second tab in alignment with said passageway and out of alignment with said lip means for removal of said second buckle part from said first buckle part.
Claim 3
Dependent Claim
32 words
The improved buckle according to claim 1, including a raised button on said first tab in the area adjacent the free end of said first tab and facing outwardly of said housing.
Claim 4
Dependent Claim
95 words
The improved buckle according to claim 1, wherein in said cavity a first step is provided in one of said side walls and extends between said end walls and terminates at said opening, and wherein said annular frame also has a second step which corresponds in shape with said first step, the maximum thickness of said second buckle part is greater than the minimum size of said passageway in said housing so that said first and second steps must be properly aligned before said first buckle part can become coupled to said second buckle part.
Claim 5
Dependent Claim
31 words
The improved buckle according to claim 3, wherein said first step is provided on the wall of said housing opposite said first tab and lying in a vertical plane of symmetry.
Claim 6
Dependent Claim
22 words
The improved buckle according to claim 3, wherein said first step is provided on the end wall having said passageway therein .
Claim 7
Dependent Claim
35 words
The improved buckle according to claim 3, wherein said cavity is constructed in form of a wedge and wherein said second buckle part has a wedge shape to conform to the shape of said cavity.
Claim 8
Dependent Claim
57 words
The improved buckle according to claim 1, wherein the one of said side walls opposite said first tab and adjacent said passageway has limiting means for limiting the movement of said second tab from said normal position thereof so that said second tab will be assured of alignment with said passageway upon engagement with said limiting means.
