FOLDING PLAYPEN Filed Sept. 28. 1961 2 Sheets-Sheet 2 INVENTORS MAX A. 5/5654, /PQBEQT l/. JA C055 BY f @5R/AN e BLACK/9AM TTIQNEYS United States Patent O 3,183,528 FOLDING PLAYPEN Robert V. Jacobs, Los Angeles, and Max L. Siegel, Santa Monica, Calif., assignors to Baby Line Furniture Corp., Los Angeles, Calif., a corporation of California Filed Sept. 28, 1961, Ser. No. 141,329 1 Claim. (Cl. 5-99) This invention pertains to new and improved structures of a type commonly referred to as folding playpens or play yards. More specifically it pertains to folding playpens or play yards utilizing features embodied within folding play yards as set forth in the Landry US. Patent 2,489,188, but which constitute an improvement over the play yards referred to in this patent.

In the above-noted Landry patent folding playpens or play yards are set forth which include opposed end walls having their edges or ends connected by means of side walls, and incorporating a floor structure which is pivotally connected to the end walls and the side walls employed. This general type of structure is considered to be advantageous inasmuch as it is of such a nature that it can be conveniently folded into a relatively fiat coniiguration for storage or other purposes. Similarly the general type play yard set forth in the Landry patent can be easily unfolded to an operative or open conhguration with very little diiliculty.

Unfortunately in several regards the structure shown in the Landry patent is not considered to be completely satisfactory for all commercial purposes, although structures as shown in this Landry patent have been manufactured and sold in quantity and unquestionably are of a very `desirable character. Specifically, in structures as shown in the Landry patent it is necessary to provide connecting latches at the adjacent ends of the side walls employed in order to achieve the rigidity in the entire structure necessary for it to be satisfactorily utilized. Obviously these connecting latch means must be connected and disconnected as a structure shown in the Landry patent is being opened or folded. Also, because of the specic locations of the various parts in the Landry patent sliding hinge or equivalent structures must be employed between the side walls and adjacent floor sections in the Landry structure in order to achieve a satisfactory folding action permitting the various sections of the floor shown in this patent to lie substantially flat during the use of a play yard or playpen as set forth in this patent. Such sliding hinges are relatively expensive; in addition, inherently such sliding hinges or equivalent structures are prone to maloperation.

An object of the present invention is to provide new and improved fol-ding playpens or play yards which utilize construetional features as set forth in the Landry Patent 2,489,188, but which diff-er from the structures shown in this Landry patent in that they do not require sliding hinges or equivalent structures as briefly referred to in the preceding paragraph, and in that when in an unfolded or open position they do not require various latch connections or the like in order to be rigid. Related objects of this invention are to provide playpens or play yards of the type indicated in the preceding which are comparatively simple to manufacture `and construct, which can be sold at an economically competitive price and which may be easily folded and unfolded as required during their utilization.

These and various other objects and advantages of this invention will be more fully apparent from a detailed consideration of the remainder of this specification including the appended claim and the accompanying drawings in which:

FIG. 1 is a top plan view of a folding playpen of this invention in an open position;

3,183,528 Patented May 18, 1965 ICC FIG. 2 is a top plan of this folding playpen in a folded configuration;

FIG. 3 is a partial cross-sectional view taken at line 3-3 of FIG. 1

FIG. 4 is a cross-sectional view taken at line 4 4 of FIG. 2;

FIG. 5 is a partial, enlarged top plan view of the playpen shown in the preceding figures in the process of being moved between a folded and open position; and

FIG. 6 is a cross-sectional view corresponding to a view taken at line 6-6 of FIG. 5.

The accompanying drawings are based upon a presently preferred embodiment or form of a folding playpen or play yard of the present invention, but they do not illustrate this presently preferred playpen or play yard in an exact engineering sense so as to show various parts of this playpen at a scale corresponding to the dimensions of parts of it. This is because the accompanying drawings are primarily intended so as to clearly illustrate or explain the features of the present invention, and because these drawings can best accomplish this function by varying slightly from the precise relative sizes and shapes of various parts of the actual playpen upon which the drawings are based.

As an aid to understanding this invention it can be stated in essentially summary form that it concerns folding playpens or play yards, each of which is constructed so as to include opposed end walls, each of which carries two side walls and a center floor section. In a playpen or yard of this invention the extremities of the side walls remote from the end walls are hinged together, and side floor sections are hinged to these side walls and to the center floor sections employed in such a manner that the entire assembly is simultaneously capable of being folded or unfolded as a unit from or to an open or a folded position, and in such a manner that when this assembly is located in an open position the various parts of the playpen or play yard are held together so as to achieve a type of locking action which serves to eliminate the necessity for latches or the like serving to provide rigidity to the structure.

The actual details of this invention will be more fully vapparent from a consideration of the accompanying drawings in which there is shown a folding playp-en or play yard 10 of the present invention having opposed, identically formed end walls 12. Each of these end walls incorporates a framework having vertical parallel end members 14 joined by a bottom member 16 and a top rail 18. In each of the end walls 12 the bottom member 16 is parallel to the top rail 18, and further the

members

14, 16 and 18 are located within a single plane. The flower ends of the

end members

14 and 16 and the rails 18 are cl-osed by a screen-like, flexible net 22; other related structures can be employed for the same purpose.

From a consideration of the drawing it will be realized that when the end walls 12 are located in an open position so as to be spaced from one another that these end members 14 are joined by side walls 24. Each of the side walls 24 includes a U-shaped framework consisting of an end member 26, a bottom member 28 and a top rail 30. The extremities 32 of the end members 28 and the top rails 30 serve as end members for the side walls. Other nets 22 of the same type as the nets 22 previously described join the members 2'6 and 28 and the top rail 30 of two of the side walls 24 which are located next to one another.

In this structure hinges 34 connect the

end members

14 and 26 while other hinges 36 connect the extremities 32 of the end members 26 and the top rails 30 so as to hold the side Walls 24 in alignment with one another as illustrated in FIG. 1 when the playpen 10 is in an open position. The hinges 36 are preferably of a character s, 1 sagen@ 3 n permitting rotation between the side walls-24 only rn an inwardly direction toward the center of tite playpen: 1t). When they are in an open position the extremities 312k abut against one another as illustrated 1n P IG. 1.

In the playpen center iioor sections 38 of a trapezoidal shape having base edges 40, diagonal edges t42 and top edges 44 are located so that the base edges; 4i) are attached to `and extend along the lengthsy of they bottom members 16 of the end walls 12 through the; use of hinges 46. These hinges 45 are all disposed 1n such a manner that their axes of rotation lie within same plane as the axes of rotation of the hinges 34 `connected to the same end walls 12. k

Other hinges 48 connectthe diagonal edgestdz.V of the center oor sections 38 to what may be referrece as the hypotenuse edges 5070i the side oor sections Sie; Each of these -side wall sections 52 has a base edge 541s which extends along the length of and is secured .to one of the bottom members 28 by means of a single hmge 55. The hinges 56 are of the same general category as the rei-Sgt of the

hingesy

34, 36, 45 and 48 employed 1n the playpenfti, they are constructed in such a manner as not topermit any sliding movement between the side oor sections rl52 and the corresponding bottom members 28 ofthe side walls 24.

The side tloor sections 52 are also constructed so as tot include perpendicular edges 58 which extend from the: base edges 54at a right angle t0 these ba'se edges. When; the playpen 10 is in an open kconfiguration as lllustratedj* in FIG. 1 of the drawing the perpendicular edges S8 and; the top edges 44 are all aligned with one'another and abut against one another. Preferably thediagonal edges 42 and the hypotenuse edges 50 are also located against one another in this open position; these

edges

44 and 50 are also preferably located in thistopen position so'as to extend at angles to the end walls 12 and the side walls 24.

The playpen 10 also preferably lncludes a foot pedal 62 which is rigidly secured to one of the center floor sections 3sat about its midpoint so as to extend from it beneath the bottom'member 16 of one of the end Walls 12. vIt may also include a bracket 66 attached to the same center iloor section 38 adjacent to the top edge 44 of this section. When the bracket '66 is used it is employed to rotatably hold a small arm 68 which is `capable of being.

rotated from a position in which it lies in a plane generally parallel to the centerfloor section 38 upon which 1t 1s supported to a position in which it extends from this center iioor section 38 at a right angle so as to be capable of engaging a ioor (not shown) when the playpen 10 is in an openr position for the purpose of supporting the center portion of this floor.

As the'playpen 10 is normally shipped or supplied to a consumer it is in a folded configuration in which the various parts of it are disposed as indicated in FIG. 2 of the drawings. When this playpen 10 is to be used the end walls 12 are moved away from one another 1n such a manner as to remain generally parallel.k When the walls 18 have been moved a sufficient distance so as to provide for a space (not shown) generally between the edges 44 of the center floor sections38 the arm 68 may be rotated so as to extend at a right angle from the section .38 holding it, and may be latched in place. Then the walls 12 are moved further apart .until they are approximately in the position shown in FIG. 1 of the drawings. n

The .playpen 10 is dimensionedso that 1n th1s uposition the distance between the extremities 32 of the bottom member 28 is slightly less than the total distancetor length .of the edges 58 Vand 44 of the .side oor sections 52 and the center oor sections `38 extending across the. entire playpen 10 roughly parallelrto the end walls 12. An this point a very small amount of .pressure can b e applied to any one of the

sections

38 or 52, or to the sidewalls 24 4 so as it@ spring Vthe

sections

38 and 52 to a position cor- :responding to an over center toggle type position in which l fthe edges S8 and 44 extend a comparatively short dis- Stance below a line drawn between the extremities 32 of nhe bottom members 28. When this occurs the base edges 54 of the side Vlioor sections-52 are supported by the lbottom members 28. Further, the action achieved in athismanner locksA the entire playpen-10 so that there :is Anognecessity for securing they side Walls 24 to one an- -other lby latches orthe like Further, at this point the playpen 10 can be folded'to a foldedvconliguration as inrdicated. in FIG. 2 of the drawings by stepping upon the pedal 62 and reversing the series of operations Ydescribed in the preceding.

Those skilled in the art to which this invention pertains 7 twill realize thatthe playpen 10 is a very eicient, effecztive device which constitutes a deinite improvement over prior closely related structures such as are shownin the .aforenoted Landry U.S. Patent No. 2,489,l88. They will :also realize that playpens'such as the playpen 10 may be easily and conveniently used, and that because of the construction features embodied within these playpens there is no necessity for using with them sliding hinges or the like which, as pointed out in the initialportions of this specification, are relatively undesirable in a structure as described. Because of the nature of this invention it is tol be considered as being limited only by the appended cla im forming a part of this disclosure.

We claim:

In a folding play yard having in an unfolded position a jpair, of opposite end Wallmembers, a pair of connecting folding side wall members hingedly pivoted between :said end wall members, a center oor member adjacent reach end wall memberV and hingedly pivoted to its adjacent tend vwall member, and a side iioor member adjacent each side `of each of said center iioor members and hingedly pivoted thereto at adjacent edges, each of said side oor members being hingedly pivoted to the adjacent part of its :adjacent folding side Wall member so that rsaid folding side Wall members and said center and side iloor members lare simultaneously foldable, one by the movement of the Iother, the improvement which comprises:
