Abstract
Abstract A children''s playseat comprises two inverted U-shaped members whose legs are pivoted together to form a pair of spaced-apart scissor frames. A rigid bearing plate is mounted between the legs at each pivot point. Each plate has one or more tongues at its periphery which extend transversely to the plane of the plate and engage a leg of the scissor frame to prevent the plate from turning relative to that leg. The plate also has one or more other tongues at its periphery which extend in the opposite direction from the first tongue and which engage the other leg of the frame when the scissor frame is opened to its operative position to limit the further opening of the scissor frame. A cup-like housing engages over the plate and leg portions at the site of each pivot point to shield the occupant''s fingers from pinch points at that location.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
A child''s playseat of the type having a pair of generally Ushaped frame members, pivotal connections between the corresponding legs of the frame members and a flexible seat supported by the frame members, the improvement comprising a stop member situated at each pivotal connection between the corresponding legs of said members, said stop member having integral portions thereof overlying the legs and engaging the legs when they are open to a selected angle relative to one another which is appropriate for supporting the seat above the ground, and a rigid housing engaging over the outermost leg and the stop member at the site of each pivotal connection so as to shield the fingers of the playseat''s occupant from pinch-points in the region of that connection.
Claim 2
Dependent Claim
125 words
A child''s playseat of the type having a pair of generally Ushaped frame members, pivotal connections between the corresponding legs of the frame members and a flexible seat supported by the frame members, the improvement comprising a stop member situated at each pivotal connection between the corresponding legs of said members, said stop member having integral portions thereof overlying the legs and engaging the legs when they are open to a selected angle relative to one another which is appropriate for supporting the seat above the ground, and a rigid housing engaging over the outermost leg and the stop member at the site of each pivotal connection so as to shield the fingers of the playseat''s occupant from pinch-points in the region of that connection.
Claim 3
Dependent Claim
30 words
The playseat defined in claim 1 wherein the stop member has a first integral tab overlying one of the legs and at least one integral tab overlying the other leg.
Claim 4
Dependent Claim
23 words
The playseat defined in claim 1 wherein the housing is generally cylindrical and has slotted side walls for accommodating one of the legs.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
133 words
A child''s playseat of the type having a pair of generally U-shaped frame mebers, pivotal connections between the corresponding legs of the frame members and a flexible seat supported by the frame members, the improvement comprising a plate secured between the legs at each pivotal connection, a first tab integral with each plate and extending out in one direction from the plate, a second tab integral with the plate and extending out in the opposite direction from the plate, said tabs engaging the adjacent legs when the legs are opened so that they are substantially perpendicular to one another to prevent further opening of the legs, a rigid cap-like housing engaging over the outer leg and the plate at each pivotal connection and means for securing the housing in place at said connection.
Claim 7
Dependent Claim
