Abstract
Abstract A child's playset comprised of a number of rooms offering different stage settings which may be changed. Each room includes a pair of walls at an angle with respect to each other and a floor having two different heights. The playset is preferably formed by attaching four rooms together at hinges whereby the rooms may be moved with respect to each other to form different shaped playsets. In addition, the rooms may be brought together to form a square wherein a handle extending upwardly from the walls of each room come together to form a central carrying handle for transportation of the playset.

Dependent Claim
161 words
A child's playset comprising: a square base member including a generally horizontally extending floor having a front edge, a rear edge, a first side edge, and a second side edge, said base member also including an encompassing sidewall depending from said edges; a first wall removably secured to said second side edge of said floor, said first wall including a handle member extending upwardly, away from said floor, whereby said playset may be picked up and transported; a second wall removably secured to said floor along a line extending diagonally at least partially across said floor from one corner of said rear edge to the diagonally opposite corner of said front edge; and means affixed to diagonally opposite corners of said square base member to enable at least four playsets to be rotatably held together and rotated with respect to each other about axes perpendicular to said floors whereby said four playsets may be brought together to form an enlarged square.
Claim 3
Dependent Claim
34 words
A child's playset as recited in claim wherein said handle members on adjacent first walls are brought together into abutting relationship at the center of said enlarged square to form a central carrying handle.
Claim 4
Dependent Claim
207 words
A child's playset comprising: a square base member including a generally horizontally extending floor having a front edge, a rear edge, a first side edge, and a second side edge, said floor being divided into two different levels by a wall extending diagonally across said floor along a line from one corner of said rear edge to the diagonally opposite corner of said front edge, said base member also including an encompassing sidewall depending downwardly from said edges. a first wall removably secured in holes formed along said second side edge of said floor; a second wall removably secured in holes formed along said line extending diagonally to partially separate and two different levels of said floor; a first means affixed to said one corner of said rear edge and a second means affixed to said diagonally opposite corner of said front edge for articulately connecting a plurality of a said base members together for relative rotation about an axis perpendicular to said floor; and a handle member extending upwardly from said first wall, away from said floor, whereby a plurality of said playsets may be rotated about associated ones of said first and second means to bring associated ones of said handle members into abutting relationship.
Claim 5
Dependent Claim
207 words
A child's playset comprising: a square base member including a generally horizontally extending floor having a front edge, a rear edge, a first side edge, and a second side edge, said floor being divided into two different levels by a wall extending diagonally across said floor along a line from one corner of said rear edge to the diagonally opposite corner of said front edge, said base member also including an encompassing sidewall depending downwardly from said edges. a first wall removably secured in holes formed along said second side edge of said floor; a second wall removably secured in holes formed along said line extending diagonally to partially separate and two different levels of said floor; a first means affixed to said one corner of said rear edge and a second means affixed to said diagonally opposite corner of said front edge for articulately connecting a plurality of a said base members together for relative rotation about an axis perpendicular to said floor; and a handle member extending upwardly from said first wall, away from said floor, whereby a plurality of said playsets may be rotated about associated ones of said first and second means to bring associated ones of said handle members into abutting relationship.
Claim 6
Dependent Claim
238 words
A child's playset comprising: a square base member including a floor having a front edge, a rear edge, a first side edge, and a second side edge, said floor being divided into two different levels by a wall extending diagonally across said floor along a line from one corner of said rear edge to the diagonally opposite corner of said front edge, said base member also including an encompassing sidewall depending downwardly from said edges; a first wall removably secured in holes formed along said second side edge of said floor; a second wall removably secured in holes formed along said line to partially separate said two different levels of said floor; a first hinge element affixed to said one corner of said rear edge and a second hinge element affixed to said diagonally opposite corner of said front edge for articulately connecting four playsets together whereby said four playsets may be rotated with respect to each other about axes perpendicular to said floors to form different play configurations; and a handle member formed integrally with and extending upwardly, away from said floor, on said first walls secured in each of said four playsets, whereby said handle members on adjacent first walls may be brought together into abutting relationship to form a central carrying handle at the center of an enlarged square formed by said four playsets, when said playsets are rotated together to form an enlarged square.
