PORTABLE PLAY PEN BACKGROUND OF THE INVENTION The invention relates to play pens for children in general and in particular to a play pen foldable to a compact unit that may be carried about and quickly opened to usable form.
An important object of the invention is to provide a foldable, portable play pen which can be manufactured and distributed at a reasonable cost.
These objects will become apparent from the following description and the drawing.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawing, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
In the drawing:
FIG. 1 is a perspective view of the play pen in erected, unfolded position;
FIG. 2 is a view from the bottom of the unfolded floor of the pen;
FIG. 3 is a cross-section taken on line 3-3 of FIG. 4;
FIG. 4 is a section taken on line 4-4 of FIG. 3;
FIG. 5 is a cross-section taken on line 5-5 of FIG. 2,
FIG. 6 is a cross-section taken on line 6-6 of FIG. 1 and FIG. 7 shows a carrying case with a hendle for the convenient carrying of the play pen, and
FIG. 8 is a section taken on line 8-8 of FIG. 1.
Referring now to the invention in detail, there is shown in FIG. 1 a play pen 8 constructed in accordance with the objects of the invention. The play pen comprises a floor consisting of triangular sections of rectangular sections 16 of Masonite, beaverboard or plywood, and of spacers such as 40, 42 secured to a fabric sheet 18, so that they may be folded together along their adjacent edges indicated by dotted lines in FIG. 2. A removable padding 19 with a cover 21 is placed over the floor 9. Four tubular posts 10, preferably of aluminum, for lightness, are hingedly secured at their lower ends to pairs of plates 12 which are formed with opposed integral hinge pins 14 extending into the lower ends of the posts. Plates 12 are secured to the corners of the bottom faces of triangular sections 16. When erected the posts 10 are held in a vertical position by means of a slotted slide 20 displaceable on screws 21 and terminating as a lock pin 22, which is ex tended through aligned holes 24 when the play pen is unfolded for use. The bottom ends of posts 10 are provided with semi-spherical resilient bumpers 26 and assymetrically positioned bumpers 27 on the triangular floor sections 15,16, to space the floor sections from a supporting surface while providing rigidity for the latter when they are unfolded.
Two of the triangular sections 15 are each provided with an aperture 28, through which extends a handle 30. The handle 30 is adapted to lie flat on the pad 19, 21 when the play pen is erected, so that it will not interfere with the movements of a child about the floor 9. Handle 30 may be pulled out however, after the posts 10 are unlocked, to pull the floor sections upward in order to fold these together.
Secured to the posts 10 and the peripheral edge of floor 9 is a netting 32, preferably of nylon or other sturdy synthetic material. The upper edge of net 32 is attached at 34 to an annular bumper 36 of suitable fabric enclosing a resilient core 38 of rubber or plastic material secured to the upper portions of posts 10.
In order to conveniently carry the folded play pen 8, there is provided a carrying bag or cover 40 having a zipper 42 and a carrying handle 44.
It will be noted that in addition to the main cut eges such as indicated by dotted lines 40, the triangular sections are also provided with additional cut edges such as 42. The purpose of the additional cuts is to provide spaces between the triangular sections, when folded, for receiving the posts 10.
1. A portable, foldable play pen comprising a floor made of a plurality of flat triangular sections having a base and intersecting sides, a plurality of flat quandrangular sections arranged alternately of said triangular sections, a plurality of flat spacers disposed adjacent intermediate one of the sides of said triangular and said quadrangular sections, means permanently hingedly securing said sections to one another, a plurality of vertically erectable spaced posts hingedly secured to said quadrangular sections, hinge means for said posts, means for rigidly securing said posts in erected position, a netting secured to said posts and to the outer edges of said sections, said netting forming walls of said play pen and bumpers attached to the top portions of said posts and top edges of said netting, said triangular, said quadrangular sections, when folded in accordionlike fashion, forming chambers with spacers for receiving said posts, said hinge means being a pair of angularly disposed plates terminating as hinge pins opposed to one another said plates being secured to said foldable sections, posts having lower end portions provided with a first pair of aligned holes for receiving said hinge plns.
2. The play pen as claimed in claim 1, wherein said means for securing said foldable section is a flexible fabric.
