13 Claims. (Cl. -99) The present invention relates to playyards or playpens for babies, and more particularly to a foldable playyard or playpen.

The conventional babies playyard or playpen is made of wood and is slatted. It is heavy, awkward, and cumbersome to handle, and sometimes difficult to fold. The baby can easily push his or her toys through the slats in the yard, causing mother much stooping and bending to collect the toys again. Moreover, prior to folding the conventional playyard up, the toys as well as the pad, which is used to cover the floor of the playyard, when the playyard is in use, must be removed from the playyard, and stored somewhere where they are available for In the conventional playyard also the floor ordinarily warps out of shape because one part of the floor has to support the other part thereof.

One object ofthe present invention is to provide an improved babies playyard which will be light in weight while having the requisite strength, which will be easy to carry about and to transport, easy to handle, and which can quickly and readily be folded or unfolded.

Another object of the invention is to provide a playyard which can be folded or unfolded in one motion.

A further object of the invention is to provide a playyard which will be compact when folded and occupy a minimum of space.

Another object of the invention is to provide a playyard so constructed so that the babys toys and the floor pad can be folded intothe playyard itself, obviating any problem of storing them or of looking for them when the playyard is to be used again.

Another object of the invention is to provide a playyard so constructed that the baby cannot push toys out through the sides of the playyard.

A still further object'of the invention is to provide a playyard in which the floor will be self-supporting, and such that it will resist warping.

Other objects of the invention will be apparent hereinafter from the specification and claims when read in conjunction with the accompanying drawings.

In the drawings:

Fig. 1 is a side elevation of a playyard constructed according to one embodiment of this invention, with the playyard opened up in position for use;

Fig. 2 is a side elevation showing the playyard partly folded;

Fig. 3 is an end view taken at right angles to Fig. 1, also showing the playyard in open position;

Fig. 4 is a plan view of the opened playyard, with part of the floor pad broken away to show the floor itself, part of the sleeve, from which the flexible body of the playyard is suspended, being broken away also, to show part of one of the tubular frame members;

Fig. 5 is a fragmentary section taken on the line 5-5 of Fig. 4 looking in the direction of the arrows;

Fig. 6 is. a fragmentary section taken on the line 66 of Fig. 5 looking in the direction of the arrows;

Fig. 7 is a fragmentary section taken generally on the line 77 of Fig. 1, showing the way in which the netting is attached to the upper frame of the playyard at its upper end, and how it is fastened to the floor at its lower end;

Fig. 8 is a fragmentary section on a somewhat enlarged scale taken on the line 88 of Fig. 4 looking in the direc-- tion of the arrows; and

Fig. 9 is a fragmentary plan view of the playyard taken in a plane just above the floor, the covering pad being broken away to show how the flexible body of the playyard is secured to the floor.

The playyard shown in the drawings comprises an upper generally-rectangular shaped frame which is made in two parts, each part being in the form of a U-shaped tubular frame member. The ends of the two U-shaped frame members are in opposed relation and are close to one another. There is a supporting leg pivoted to each end of each U-shaped member. The playyard has a two-part floor. Each floor section is supported by a plurality of inverted channel members that are hingedly connected at their inner ends to the inner ends of the aligned channel members which support the other floor section. The axis of the hinged connection is parallel to the pivotal axes of the supporting legs of the playyard and moves in a vertical plane approximately midway between the points of pivotal connection of the two pairs of supporting legs with their respective frame members. The channel members for the respective floor sections are pivotally supported at their outer ends on bars which are rigidly secured to the two pairs of supporting legs. The body, or perimetric enclosure, for the playyard is flexible and is preferably made of knitted nylon net. It is suspended around the perimeter of the frame and is secured at its lower end around the perimeter of the floor. Its interstices are small enough to prevent the baby from pushing 'a toy through them, yet large enough to permit readily seeing through. To support the frame in open position, a folding brace is pivotally connected at its lower end to each supporting leg and is pivotally connected at its upper end to the associated frame member. The two floor sections are preferably made of different widths. The covering pad is preferably folded in its middle onto the wider floor section, when the playyard is to be folded. This will expose part of the wider floor section. A strap or handle is secured in the wider floor section to be exposed when the covering pad is folded. By grasping this and pulling up the whole playyard will fold, once the folding braces have been broken. Hence the legs, frame, floor, and body can be folded by the simple, single motion of pulling up on the strap in the floor. This strap serves also as a carrying strap or handle for the folded playyard. Due to the flexibility of the body, or perimetric enclosure, the toys and floor pad can be left in the playyard and folded in with the folded playyard.

Referring now to the drawings by numerals of reference, the two U-shaped tubular frame members which together constitute the frame of the playyard are denoted at 10. These frame members are of equal size and are positioned in inverted relation to one another so that the ends of their legs are adjacent and so that their legs are in alignment and their ends confront one another when the playyard is in open position. These frame members are pivotally connected at their ends by means of pivot pins .11 to inverted U-shaped caps 12 and to a pair of supporting legs 14.

Each of the legs 14 is connected by means of a foldable brace or spreader 15 to one of the U-shaped tubular frame members 10. Each brace 15 is made in two

parts

20 and 21 which are pivotally connected together by means of a pin 19. The part 20 of each brace is pivotally connected by means of the pin 16 and U-clip- 17 to the associated leg 14 intermediate the ends of the leg. The part 21 is pivotally connected by means of pin 18 to the associated U-shaped frame member 19 at a point spaced from one end of the frame member. The brace part 26 has a stop ledge 22 stamped thereon, which is adapted to engage against the surface 23 (Fig. 2) of the brace part 21, when the brace is in its extended position, to limit the movement of the brace part 21 on the brace part 29 and hold the brace in extended position. The brace part 21 has an L-shaped stop or look 24 slidably secured there on by means of a pin 25, which engages in the slot 26 in one leg of the lock 24. Each lock 24- is adapted to be engaged under the associated brace part 20, when the brace is extended, as shown in Fig. l, to support the brace in its extended position and prevent involuntary collapse of the playyard. The stops or locks 24 further serve to prevent a child from folding the playyard.

The opposed legs 14 of each pair of supporting legs are connected together adjacent their lower ends by an inverted U-shaped supporting bar 30 whose legs are riveted by means of rivets 31 (Figs. 1 and 3) to the opposed legs 14 at the insides thereof. Mounted on each of the rods 30 and longitudinally spaced from one another therealong is a plurality of inverted channel members. The channel members associated with one of the rods 30 are denoted at 32; and the channel members associated with the other rod 30 are denoted at 33. The

channel members

32 and 33 are of equal length and are arranged in pairs. The two channel members of each pair butt against one another at their proximal ends and are hingedly connected at such proximal ends by means of hinge pins 34, the channel members 32 being formed with ears 34 (Fig. to straddle the channel members 33 at their proximal ends. The hinge pins 34 for the channel members lie and move in a vertical plane intermediate the pivots 11 for the legs 14.

The floor of the playyard is supported by the

channel members

32 and 33. This floor is made in two pieces, one of which 35 (Fig. 4) is considerably wider than the other piece 36. The two sections of the floor are riveted to the

channel members

32 and 33, respectively, by rivets 37. The diiference in width of the two

floor sections

35 and 36 makes the line of break between these two sections offset from the hinge plane of the channel members.

To strengthen the floor, a wire truss rod 40 (Figs. 3 and l) is riveted at its opposite ends, by means of rivets 41 to each of the cross bars 30 beneath the same. To prevent sidewise movement of the rods 40 relative to their respective cross bars 30, there is a V-shaped clip riveted to each of the bars 30 approximately midway the length thereof; but one of the clips 42 is disposed at one side of the longitudinal center line of the playyard, and the other clip 42 associated with the other rod 40 is disposed at the opposite side of the longitudinal center line. This is to avoid interference with the

channels

32 and 33 when the playyard is being folded.

The body or enclosing portion of the playyard is made of a flexible material, such as nylon netting, which is denoted at 45. This netting is shown only fragmentarily in the figures for clarity of illustration. The netting 45 extends all around the playyard inside the legs 14 thereof. It is suspended at its upper end from the U-shaped frame members by means of a fabric sleeve 46, to which it is sewed, or otherwise fastened. The sleeve 46 may be cut away adjacent the pivots 11 of the legs to permit ready folding. The sleeve may be made of plastic or any suitable fabric. At its lower end the netting 45 is sewed or otherwise secured to another sleeve 48, which covers a pair of U-shaped straps 49 (Figs. 7 and 9) that are disposed, similar to the U-shaped frame members 10, in inverted relation with their ends adjacent, and with their ends confronting one another and their legs in alignment when the playyard is open. The strap members 49 are fastened by means of rivets 50 to the respective floor sec- 4

tions

35 and 36. The legs of the U-shaped strap 49, which is attached to section35 of the floor, are somewhat shorter than the width of that floor section but the legs of the U-shaped strap 49, which is attached to the floor section 36, are somewhat longer that the width of the floor section 36 so that they underlie floor section 35 when the playyard is open, as shown in Fig. 9. However, this latter strap 49 is riveted only to floor section 36 so as to permit folding of the floor.

In use, the floor is covered by a foldable pad 55, which is made so as to fold along its middle.

Since the floor sections are of unequal width, and the floor section 35 is wider than the floor section 36, when the pad 55 is folded, it exposes part of the floor section 35. A carrying strap 56 is secured in the section 35 of the floor close enough to the free edge of that section to be exposed, as shown in Figs. 2 and 4-, when the pad 55 is folded. This strap may be made of plastic and inserted through holes 57 (Figs. 4 and 8) in the floor section 35, and may have its ends looped and heat-sealed to secure against the strap being pulled out of the floor section 35. When folded, the playyard can readily be carried by the strap 56. When extended, the playyard can readily be folded by folding braces 15 and then pulling up on the strap 56.

Assuming that the playyard is in the extended, operational position shown in Figs. 1. 3 and 4, to fold the playyard, the floor pad 55 is first folded in the middle over onto floor section 35. This exposes the carrying strap 56. The catches 24- of the braces 15 are slid back to permit the braces to fold. Then by lifting on the carrying strap 56 the whole playyard can be folded into collapsed position for easy transportation. In its collapsed position, the legs 14 at each side will be substantially contiguous, the U-shaped frame members 1t will be folded down alongside the legs, and the floor sections will be folded within the skirt or netting 45 and within the U-shaped frame members 19. The

sleeves

46 and 48 will bend at their middle sufiiciently to permit this fold. The aluminum caps 12 eliminate dangers of the fingers being pinched in folding.

To open up the playyard to position for use, a person needs only to grasp the U-shaped frame members 10, and pivot them upwardly to horizontal position, and set the braces 15 by moving the catches 24 into brace-locking position. During the upward pivotal movement of the U-shaped frame members 10, the legs will pivot apart about their pivots 11; and the floor sections will pivot about the hinge pins 34 to horizontal position. The aluminum caps 12 limit the upward movement of the frame members 11) so that these frame members are horizontal when the playyard is open. After the playyard has been opened up, the pad 55 may be opened up. The playyard is ready for use by the baby.

The legs 14 are preferably tubular and preferably the tops of the tubes which constitute these legs are spun over, instead of being capped, to facilitate folding. The legs 14, caps 12, tubular frame members 10, bars 30,

channel members

32 and 33, and straps 49 are all preferably made of aluminum to reduce the Weight to a minimum. As previously stated, the body or skirt 45 is preferably made of nylon netting for lightness, openness, flexibility and strength, but obviously may be made of other flexible materials also. The

floor sections

35 and 36 are preferably made of pressed board, which is light in weight and low in cost. The supporting

channel members

32 and 33 give the floor sections adequate support.
