Abstract
Abstract First and second frame members on a stroller partially overlap one another and are generally parallel. A latch member is pivotably connected to the first frame member and biased to a position wherein it embraces an end of the second member. The latch member has a cam surface thereon so that finger pressures may be applied to pivot the latch frame member against the spring bias or so that the end of the second member may contact the surface and pivot the latch member whereby the second member will be snapped to a latched position without finger manipulation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
188 words
A latch comprising a latch member extending between first and second frame members whose end portions overlap one another and which are generally parallel, the first frame member having one end pivotably connected to the second frame member at a location spaced from and adjacent one end of the second frame member, the latch member being pivotably supported on the first frame member and spring biased to a position wherein it embraces said ene of the second frame member, a surface on said latch member where finger pressure may be applied to release the latch member so that said first and second frame members may pivot relative to one another, said surface being a cam surface so that said one end of said second frame member may contact said cam surface to pivot the latch member and then be snapped to a latched position without finger manipulation of the latch member, said latch member being generally U-shaped so as to have legs generally parallel to one another, a loop connected by extensions to said legs so as to define a hole through which the first frame member extends.
Claim 2
Dependent Claim
188 words
A latch comprising a latch member extending between first and second frame members whose end portions overlap one another and which are generally parallel, the first frame member having one end pivotably connected to the second frame member at a location spaced from and adjacent one end of the second frame member, the latch member being pivotably supported on the first frame member and spring biased to a position wherein it embraces said ene of the second frame member, a surface on said latch member where finger pressure may be applied to release the latch member so that said first and second frame members may pivot relative to one another, said surface being a cam surface so that said one end of said second frame member may contact said cam surface to pivot the latch member and then be snapped to a latched position without finger manipulation of the latch member, said latch member being generally U-shaped so as to have legs generally parallel to one another, a loop connected by extensions to said legs so as to define a hole through which the first frame member extends.
Claim 3
Dependent Claim
37 words
A latch in accordance with claim 1 wherein said frame members are at an acute angle with respect to the horizontal with the second frame member being above the first frame member along the overlapping end portions.
Claim 4
Dependent Claim
52 words
A latch in accordance with claim 1 wherein said first frame member is an angularly disposed leg of a U-shaped frame with the bight being a pushing handle of a stroller, said second frame member being a leg of a U-shaped frame whose bight is connected to front wheels of a stroller.
Claim 5
Dependent Claim
32 words
A latch in accordance with claim 1 wherein the spring is trapped between surfaces of the latch member without being physically attached to either the latch member or the first frame member.
Claim 6
Dependent Claim
46 words
A latch in accordance with claim 1 wherein said latch member loop is a limit stop spaced from the location wherein the latch member is pivoted to the first frame member by a distance corresponding approximately to the distance between the pivot and said cam surface.
Claim 7
Dependent Claim
49 words
A latch in accordance with claim 1 wherein said cam surface is positioned so that finger pressure applied in a direction generally perpendicular to the direction in which the spring bias on the latch member is directed will release the second frame member from retention by the latch member.
Claim 8
Dependent Claim
139 words
An article of manufacure for use in coupling first and second frame members together when said frame members partially overlap and are generally parallel comprising a generally U-shaped latch member having a front end and a rear end, said member having a pair of spaced legs, each leg having a hole for pivotably connecting the latch member to a frame member, said latch member having a limit stop extending from its rear end, a cam surface on said latch member, said latch member having a recess beneath said cam surface and open at its front end, said recess being between said cam surface and the axis of said holes, and a spring associated with said latch member for biasing said latch member to a position wherein the limit stop is adapted to contact a surface of a frame member.
Claim 9
Dependent Claim
139 words
An article of manufacure for use in coupling first and second frame members together when said frame members partially overlap and are generally parallel comprising a generally U-shaped latch member having a front end and a rear end, said member having a pair of spaced legs, each leg having a hole for pivotably connecting the latch member to a frame member, said latch member having a limit stop extending from its rear end, a cam surface on said latch member, said latch member having a recess beneath said cam surface and open at its front end, said recess being between said cam surface and the axis of said holes, and a spring associated with said latch member for biasing said latch member to a position wherein the limit stop is adapted to contact a surface of a frame member.
Claim 10
Dependent Claim
18 words
An article in accordance with claim 7 wherein said spring is a coil spring located between said legs.
Claim 11
Dependent Claim
166 words
A latch comprising a latch member extending between first and second generally parallel tubular frame members whose end portions overlap one another in a manner so that their longitudinal axes lie in a common vertical plane, the first frame member having one end pivotably connected to the second frame member at a location spaced from and adjacent one end of the second frame member, the latch member being pivotably supported on the first frame member, a spring biasing said latch member to a position wherein its embraces said end of the second frame member, a surface on the latch member wherein finger pressure may be applied to release the latch member so that said first and second frame members may pivot relative to one another, said surface being a cam surface so that said one end of said second frame member may contact said cam surface to pivot the latch member and then be snapped to a latched position without finger manipulation of the latch member.
Claim 12
Dependent Claim
166 words
A latch comprising a latch member extending between first and second generally parallel tubular frame members whose end portions overlap one another in a manner so that their longitudinal axes lie in a common vertical plane, the first frame member having one end pivotably connected to the second frame member at a location spaced from and adjacent one end of the second frame member, the latch member being pivotably supported on the first frame member, a spring biasing said latch member to a position wherein its embraces said end of the second frame member, a surface on the latch member wherein finger pressure may be applied to release the latch member so that said first and second frame members may pivot relative to one another, said surface being a cam surface so that said one end of said second frame member may contact said cam surface to pivot the latch member and then be snapped to a latched position without finger manipulation of the latch member.
