Abstract
Abstract A portable playpen embodies a disassemblable base frame having elongated upright members connected thereto and defining upstanding corner posts for a rectangular enclosure in the form of a one piece fabric unit having rectangular panels defining a box-like compartment having a bottom panel joined along its edges to upstanding side panels with adjoining edge portions of adjacent side panels secured to each other. Sleeve-like members are connected to the adjoining edge portions of adjacent side panels and extend outwardly thereof in position to telescope downwardly over an adjacent corner post with such corner post being in spaced relation to the adjoining edge portions of adjacent side panels. Stop members limit downward movement of the sleeve-like members relative to the corner posts.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
161 words
A portable playpen comprising: (a) a disassemblable base frame disposed to rest on a supporting surface, (b) elongated upright members connected to said base frame in position to define upstanding corner posts, (c) a one piece fabric unit having rectangular panels defining a box-like compartment having a bottom panel joined along its edges to upstanding side panels with adjoining edge portions of adjacent side panels secured to each other, (d) sleeve-like members connected to said adjoining edge portions of adjacent side panels and extending outwardly thereof in position to telescope downwardly over an adjacent corner post with each said adjacent corner post in spaced relation to said adjoining edge portions adjacent thereto with said sleeve-like members defining vertically extending web-like members between said corner posts and said box-like compartment so that said box-like compartment is supported inwardly of and in spaced relation to said corner posts, and (e) means limiting downward movement of said sleeve-like members relative to said corner posts.
Claim 2
Dependent Claim
161 words
A portable playpen comprising: (a) a disassemblable base frame disposed to rest on a supporting surface, (b) elongated upright members connected to said base frame in position to define upstanding corner posts, (c) a one piece fabric unit having rectangular panels defining a box-like compartment having a bottom panel joined along its edges to upstanding side panels with adjoining edge portions of adjacent side panels secured to each other, (d) sleeve-like members connected to said adjoining edge portions of adjacent side panels and extending outwardly thereof in position to telescope downwardly over an adjacent corner post with each said adjacent corner post in spaced relation to said adjoining edge portions adjacent thereto with said sleeve-like members defining vertically extending web-like members between said corner posts and said box-like compartment so that said box-like compartment is supported inwardly of and in spaced relation to said corner posts, and (e) means limiting downward movement of said sleeve-like members relative to said corner posts.
Claim 3
Dependent Claim
104 words
A portable playpen as defined in claim 1 in which said disassemblable base frame comprises crossed frame members adapted to extend beneath said bottom panel and having four angularly spaced elongated members detachably connected to a centrally disposed cross member and extending outwardly relative to the center of said bottom panel with said elongated members being bowed outwardly and downwardly relative to the center of said bottom panel to provide four points of contact with said supporting surface beneath said corner posts, with the outermost portions of said elongated members in the form of upturned members which are detachably connected to said corner posts.
Claim 4
Dependent Claim
22 words
A portable playpen as defined in claim 2 in which said upturned members are connected to said corner posts by telescopic connections.
Claim 5
Dependent Claim
46 words
A portable playpen as defined in claim 1 in which the uppermost ends of said sleeve-like members are closed to provide stops in position to engage the uppermost ends of said corner posts and limit downward movement of said sleeve-like members relative to said corner posts.
Claim 6
Dependent Claim
50 words
A portable playpen as defined in claim 1 in which retainer means operatively connects each corner of said bottom panel to the corner post adjacent thereto while said sleeve-like members are telescoped downwardly over said corner posts to thus restrain movement of said bottom panel relative to said corner posts.
Claim 7
Dependent Claim
80 words
A portable playpen as defined in claim 5 in which said retainer means comprises a strap-like loop carried by each corner of said bottom panel in position to encircle the corner posts adjacent thereto, and crossed reinforcing strap-like members carried by said bottom panel in position to cross each other adjacent the center of said bottom panel and extend between oppositely disposed corners of said bottom panel, with said strap-like members being connected at each corner to said strap-like loop.
Claim 8
Dependent Claim
41 words
A portable playpen as defined in claim 1 in which a hem is provided along the upper edges of said side panels to define elongated passageways adjacent said upper edges, and at least one elongated reenforcing member extends through said passageways.
Claim 9
Dependent Claim
29 words
A portable playpen as defined in claim 7 in which a separate elongated reinforcing member extends through said hem provided along the upper edge of each said side panel.
Claim 10
Dependent Claim
34 words
A portable playpen as defined in claim 8 in which said separate elongated reinforcing member is a semi-rigid member of a diameter ranging from approximately 3/8 of an inch to 1/2 of an inch.
Claim 11
Dependent Claim
40 words
A portable playpen as defined in claim 8 in which said separate elongated reinforcing member is removable from its hem and at least one access opening is provided in its hem for inserting and removing said separate elongated reenforcing member.
