Abstract

Abstract A portable baby seat has a flexible seat portion hung from a tubular frame for cantilevered mounting on a table edge. A U-shaped horizontal frame member extends through a hollow top seam of the seat's back and sides with end portions of the member extending forwardly for engagement with the top of the table. Each of a pair of lower support arms engage the underside of the table at a point forward of the U-shaped member's engagement. Each support arm is mounted by means of a rotatable sleeve on one of the U-shaped member's end portions. Connected to each sleeve is a curved member having a downwardly extending arm portion, a forwardly extending arm portion, and an upwardly extending end portion. The downwardly extending end portion extends in a direction away from the axis of rotation of the sleeve, while the upwardly extending end portion extends in a direction towards the axis of rotation of the sleeve. The lengths of each of the lower support arms' downwardly extending arm portions is less than one-half of the distance between the sleeves. The length of each of the arms' upwardly extending end portions is less than the length of the downwardly extending arm portions. The baby seat frame folds flat into one plane by inward rotation of the lower support arms.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 539 words
A portable folding baby seat for cantilevered mounting on the edge of and above the plane of a table when in a position of use and for folding into a single plane when in a position of storage, said portable folding baby seat comprising: a flexible seat portion hung from a frame, said flexible seat portion having a generally horizontal bottom and a generally vertical back and sides when said baby seat is in said position of use, and said flexible seat portion being collapsible into a single plane when said baby seat is in said position of storage: said frame comprising: a generally U-shaped member from which said flexible seat portion hangs, said U-shaped member lying in a first plane adapted for positioning above the plane of the table, said U-shaped member including end portions extending forwardly from the top of each side of said flexible seat portion for engagement with the top of said table, and a pair of lower support arms for engagement with the underside of said table at points that are forward from the most forward points at which said end portions of the U-shaped member engage with the top of said table, each of said lower support arms including: an upper sleeve telescopingly and slideably mounted on a respective end portion of said U-shaped member for slideable positioning and rotation along the axis of said member, said sleeve having two open ends and an intermediate, cylindrically shaped tubular section with a uniform inner diameter sufficiently large to permit the sleeve to rotate about and slide along the axis of the U-shaped member, and a curved member having: a downwardly extending arm portion having one end connected to the intermediate portion of said sleeve and having a length less than one-half of the distance between said sleeves, said downwardly extending arm portion extending in a direction away from said axis of rotation of said sleeve, a forwardly extending arm portion connected to said downwardly extending arm portion, and an upwardly extending end portion connected to said forwardly extending arm portion, said upwardly extending arm portion extending in a direction towards said axis of rotation of said sleeve; whereby said downwardly and forwardly extending arm portions and said upwardly extending end portion of each lower support arm lie in a second plane that is rotated so as to be generally perpendicular to the plane of said U-shaped member when said baby seat is in its position of use, and further whereby said second plane is rotated so as to lie in said first plane when said baby seat is in its position of storage; said frame further comprising stops made from a resilient material, such as rubber, secured around the periphery of the U-shaped or sleeve members of the frame and a point forward of the point of connection of the downwardly extending arm portion and the sleeve near the end portions of said U-shaped member and said frame further including means coupled to the U-shaped member for preventing the sleeves which are telescopingly mounted for rotation from being inadvertently removed therefrom while allowing disassembly of the lower support arms from the U-shaped member, as well as removal of the flexible seat portion when detached.
Claim 2
Dependent Claim 539 words
A portable folding baby seat for cantilevered mounting on the edge of and above the plane of a table when in a position of use and for folding into a single plane when in a position of storage, said portable folding baby seat comprising: a flexible seat portion hung from a frame, said flexible seat portion having a generally horizontal bottom and a generally vertical back and sides when said baby seat is in said position of use, and said flexible seat portion being collapsible into a single plane when said baby seat is in said position of storage: said frame comprising: a generally U-shaped member from which said flexible seat portion hangs, said U-shaped member lying in a first plane adapted for positioning above the plane of the table, said U-shaped member including end portions extending forwardly from the top of each side of said flexible seat portion for engagement with the top of said table, and a pair of lower support arms for engagement with the underside of said table at points that are forward from the most forward points at which said end portions of the U-shaped member engage with the top of said table, each of said lower support arms including: an upper sleeve telescopingly and slideably mounted on a respective end portion of said U-shaped member for slideable positioning and rotation along the axis of said member, said sleeve having two open ends and an intermediate, cylindrically shaped tubular section with a uniform inner diameter sufficiently large to permit the sleeve to rotate about and slide along the axis of the U-shaped member, and a curved member having: a downwardly extending arm portion having one end connected to the intermediate portion of said sleeve and having a length less than one-half of the distance between said sleeves, said downwardly extending arm portion extending in a direction away from said axis of rotation of said sleeve, a forwardly extending arm portion connected to said downwardly extending arm portion, and an upwardly extending end portion connected to said forwardly extending arm portion, said upwardly extending arm portion extending in a direction towards said axis of rotation of said sleeve; whereby said downwardly and forwardly extending arm portions and said upwardly extending end portion of each lower support arm lie in a second plane that is rotated so as to be generally perpendicular to the plane of said U-shaped member when said baby seat is in its position of use, and further whereby said second plane is rotated so as to lie in said first plane when said baby seat is in its position of storage; said frame further comprising stops made from a resilient material, such as rubber, secured around the periphery of the U-shaped or sleeve members of the frame and a point forward of the point of connection of the downwardly extending arm portion and the sleeve near the end portions of said U-shaped member and said frame further including means coupled to the U-shaped member for preventing the sleeves which are telescopingly mounted for rotation from being inadvertently removed therefrom while allowing disassembly of the lower support arms from the U-shaped member, as well as removal of the flexible seat portion when detached.
Claim 3
Dependent Claim 41 words
A portable baby seat as defined in claim 1 wherein the length of said upwardly extending end portions of each of said lower support arms is less than the distance of said downwardly extending arm portions of said lower support arms.
