A foldable playpen comprising: a) a frame including: i) an upper frame assembly having a plurality of collapsible upper rails and securing means for releasably maintaining said upper rails in a non-collapsed position, ii) a lower frame assembly including: A) first and second auxiliary lower floor support legs, B) pivoting means for pivotally connecting said first and second lower floor support legs at an inner end thereof to permit said legs to be pivoted in a first plane between a first substantially in-line position and a second folded position in which the legs are substantially parallel to each other, C) a plurality of lower floor support rails having inner and outer ends, the inner end of each said lower floor support rail being pivotally connected to one said auxiliary lower floor support leg at a position spaced from said pivoting means for movement in a second plane substantially transverse to said first plane; iii) a plurality of corner legs, each leg having an upper end and a lower end, iv) connecting means for interconnecting said upper rails of said upper frame assembly to the upper ends of said corner legs and for interconnecting the outer ends of said lower floor support rails of said lower frame assembly to the lower ends of said corner legs; and b) a fabric enclosure surrounding a bottom and all sides of said frame.
Claim 3
Dependent Claim
47 words
A foldable playpen according to claim 1, wherein said pivoting means includes an inverted U-shaped bracket encompassing inner ends of said first and second auxiliary lower floor support legs and pivot pin means for pivotally connecting said auxiliary lower floor support legs to said inverted U-shaped bracket.
Claim 4
Dependent Claim
54 words
A foldable playpen according to claim 1, wherein there are four lower floor support rails, two of said lower floor support rails being pivotally connected with said first auxiliary lower floor support leg and the remaining two of said lower floor support rails being pivotally connected with said second auxiliary lower floor support leg.
Claim 5
Dependent Claim
24 words
A foldable playpen according to claim 3, wherein the outer ends of said lower floor support rails are pivotally connected to said connecting means.
Claim 6
Dependent Claim
35 words
A foldable playpen according to claim 1, wherein the inner end of each said lower floor support rail is pivotally connected to one said auxiliary lower floor support leg at a position substantially mid-way therealong.
Claim 7
Dependent Claim
31 words
A foldable playpen according to claim 1, further including bracket means for pivotally connecting the inner end of each said lower floor support rail to said auxiliary lower floor support leg.
Claim 8
Dependent Claim
20 words
A foldable playpen according to claim 1, wherein there are four said upper rails arranged in a substantially rectangular configuration.
Claim 9
Dependent Claim
46 words
A foldable playpen according to claim 1, wherein each said upper rail includes a first rail section and a second rail section, and said securing means including a plurality of securing elements, each securing element pivotally connecting adjacent ends of the rail sections of the same.
Claim 10
Dependent Claim
67 words
A foldable playpen according to claim 8, wherein each said securing element includes a medial saddle member formed by two substantially rectangular plates and a central, inverted U-shaped connector which connects the upper edges of said plates together so as to maintain said plates in a parallel, spaced apart relation, with said adjacent ends of said rail sections being pivotally connected at opposite ends of said plates.
Claim 11
Dependent Claim
38 words
A foldable playpen according to claim 9, wherein the length of said U-shaped connector is less than the lengths of said plates such that said plates permit upward pivotal movement of said rail sections relative to said plates.
Claim 12
Dependent Claim
100 words
A foldable playpen according to claim 9, wherein one of said plates of each said medial saddle member includes a pair of holes therein, and the adjacent ends of said rail sections each include a hole therein, and the adjacent ends of said rail sections each including a hole therein, a button extending through the hole therein and spring biasing means for biasing the button through the hole therein, such that engagement of each said button through one of said pair of holes in said medial saddle member results in releasable locking of said rail sections in said non-collapsed position.
Claim 13
Dependent Claim
29 words
A foldable playpen according to claim 11, wherein each said securing means includes release means for releasing the buttons from said pair of holes in said medial saddle member.
Claim 14
Dependent Claim
92 words
A foldable playpen according to claim 12, wherein said release means includes release slide means for sliding along said medial saddle member, said release slide means including projection means for pushing said buttons out of said holes in said medial saddle member when said release slide means is slid along said medial saddle member, retaining means on said medial saddle member for slidably retaining said release slide mans thereon, and spring means for normally biasing said release slide means such that said projection means is positioned out of engagement with said buttons.
Claim 15
Dependent Claim
50 words
A foldable playpen according to claim 13, wherein said release slide means has a lower surface provided with two hemispherical recesses which are normally aligned with said pair of holes of said medial saddle member to receive said buttons therein and not interfere with the locking engagement by said buttons.
