9 Claims. (Cl. 5-98) This invention relates to a collapsible structure, and more particularly to a foldable play pen of lightweight construction which may be easily transported.

`It is, therefore, an object of this invention to provide a collapsible structure which can be converted with a minimum of effort into a rigid upright assembly.

It is a further object of the invention to provide a collapsible structure that can be folded in a novel manner.

-It is another object of the invention to construct a play pen which can be readily and compactly folded.

VFurther objects and `advantages of this invention will become evident as the description proceeds and from an examination of the accompanying drawing which illustrates one embodiment of the invention and in which similar numerals refer to similar parts throughout the several views.

In the drawings:

`Figure l is a perspective view of a play pen embodying vthe invention, in upright position.

Figure 2 is a fragmentary side view in elevation of the device shown in Figure 1.

Figure 3 Iis a bottom view of the play pen in collapsed position and folded for transporting.

Figure 4 is an enlarged fragmentary side view showing lthe pivotal attachment of the legs to the upper hoop.

Figure 5 is a cross sectional view taken through the upper hoop.

' Figure 6 is a cross sectional view taken through the lower hoop.

Referring now to Figure l, there is shown a play pen constructed in accordance with the objects of the invention. The play pen is provided with an upper annular rigid frame member of aluminum tubing (see Figure 5) shaped as a continuous hoop which may be covered with an annular covering 60. The upper hoop is sup ported by four rigid legs 16 spaced at equal distances about its periphery and pivotally mounted to fold inwardly under its center when the play pen is collapsed.

The legs are constructed of solid rods bent together into a foot 17 and a pair of upper bifurcate portions 1S, 19, so as to form a generally Y-shaped configuration. The bifurcate portions are bent slightly outwardly at 20 above the foot end, inwardly at the

upper extremities

22, 23, and then laterally at their

ends

25, 26. The laterally bent ends of the legs are pivotally attached 'to

brackets

29, 30 depending from the underside of the upper hoop 15. The brackets contain

bores

31, 32 for receiving the laterally bent ends of the legs. The ends of the legs passing through the bores may be peened over to provide enlarged

knobs

35, 36 which prevent the removal of the ends and 26 from the brackets.

The foot 17 of each leg is formed by foldingrthe rodding against itself and securing the two parts at 33 as by welding. A pad 34 of resilient material may be placed on the bottom of each foot so as 'to prevent scratching and damage to a floor. I

y The legs have'a length larger than the radius, but shorter than the diameter of the upper hoop 15. This particular length allows all the legs to be folded and secured together against the bottom wall 45 by a strap, as shown in Figuref, 1

A lower annular rigid frame member of aluminum tubing is shaped as a hoop 40 of slightly smaller diameter than the upper hoop 15. The lower hoop is slidably connected to one bifurcate portion of each leg 16 by U-shaped eyelets 41 projecting from its outer periphery. The lower hoop is therefore free to slide on the legs between the foot ends and the upper laterally bent ends. When the play pen is in upright position, the lower hoop serves to stabilize and impart rigidity 'to the play pen by holding the legs adjacent their foot ends against movement.

The folded foot end 17 of the legs acts as a stop to prevent lower hoop 40 from dropping to a tloor. It will be seen that when the play pen is in upright position the eyelets lil of the lower hoop are supported by the foot end at the junction of the bifurcate portions 1S, 19.

A bottom wall is provided for the play pen, of a circular shaped hard board, such as Masonite, of a slightly larger diameter 'than the lower hoop bill, and rests thereon when the play pen is in upright position. The bottom wall may be secured to the lower hoop by straps 46 which are fastened by snaps 47 mounted to the bottom wall. (See Figure 6.)

In the middle of the ybottom wall is a strap 48 passing through a pair ot" holes 50 and under the bottom, having a snap 49 so that the vstrap may be used to hold the legs together and against the bottom when the play pen is collapsed, as most clearly shown in Figure 3. The strap also serves as a handle which may be used to pull the lower frame member toward the upper frame member when .collapsing the play pen.

Between the upper and lower hoops is secured a side wall of collapsible flexible material, such as a net, preferably of synthetic fiber. As shown in Figure 5, this net is passed over the upper hoop from the inside and held thereto by a drawstring 53 disposed under the hoop. The lower end of the -net passes under the bottom flooring and is held in position by a drawstring 54.

A resilient covering oil, preferably of vinyl plastic, of annular shape with a continuous open side, shown in Figure 5, may be placed over the upper hoop to hold the netting in position. Such a covering also permits rolling of the play pen on the upper hoop when it is to be transported without soiling of the netting.

In order to collapse the play pen from the upright position shown in Figure l, into the position shown in Figure 3, the operator reaches into the play pen, grasps the strap 48, and pulls the bottom wall upwardly, which moves the lower hoop toward the upper hoop. This automatically folds the legs inwardly under the middle of the bottom wall. The bent

upper extremities

22, 23 provide suilicient clearance to allow the legs to fold over the bottom hoop and to -be laid against the bottom wall. The length of the legs being greater than the radius causes them to cross at the middle of the bottom wall so that they may be held together as in Figure 3, by strap 48.

in order to set up the play pen from the folded position in Figure 3, the strap 48 is first loosened to free the legs. The upper hoop is then grasped with both hands and held horizontally. By merely shaking the play pen the legs automatically unfold and the bottom wall drops to the proper position on lower hoop 40, which in turn rests on the stop of foot end 17 of the legs.

In the drawing and specification there has been set forth a preferred embodiment of the invention and although specific terms are employed they are used in a generic and descriptive sense only and not for purposes of limitation. Changes in form and in the proportion ot' parts, as well as the substitution of equivalents are contemplated as circumstances may suggestV or render expedient without departing from the spirit or scope of this invention as further defined in the following claims.
