This invention relates to a playard. More specifically, this invention relates to a collapsible playard and a collapsible frame structure and latch assembly for the playard.
Various types of collapsible frame structures for a juvenile product, such as a playpen, cot or bed, are known.
One known frame structure, for example, is for a portable playpen. The frame structure includes top rails, a plurality of rods arranged in X-shaped pairs equal in number to the sides of the playard, and a locking hinge arranged between each respective top rail of the playpen and a pivot point of the respective rod pairs.
Another known frame structure, suitable for a playpen or cot, includes four upper frame joints and four lower frame joints pivotably connected to frame legs, where the upper frame joints and lower frame joints are respectively located in the upper and lower corners to form a box structure. The box structure also includes a bottom base frame with four legs radially extending from a central coupling joint that allows the four legs to fold relative to the central joint and that facilitates the collapse of the entire structure.
There is a need in the art for a frame structure that may be unfolded to encompass a relatively large area, yet also provides sufficient protection and containment for a child inside the playard and remains light weight for good portability.
An aspect of the present invention relates to a collapsible frame structure. The structure comprises a plurality of legs; a plurality of cross members arranged in pairs, each pair of cross members extending between respective adjacent legs; a plurality of slider joints, each slider joint slidingly engaging a respective one of the legs and pivotably attached to two adjacent cross members; a plurality of pivot joints, each pivot joint at a respective one of the legs to pivotably attach two adjacent cross members; and at least one latch mechanism configured to selectively engage at least one of the slider joints with a respective leg.

The latch assembly comprises a slider joint slidingly engaging a leg of the playard; a handle pivotably attached to the slider joint; a first latch member configured to be attached to the leg; and a second latch member attached to the handle and configured to engage the first latch member to prevent the slider joint from sliding relative to the leg.
Another aspect of the present invention relates to a collapsible frame structure for a playard. The collapsible frame structure comprises a plurality of legs; a plurality of cross members arranged so that at least one cross member extends between, and is pivotally connected to, respective adjacent legs to form a side of the playard; a plurality of slider joints, each slider joint slidingly engaging a respective one of the legs; a plurality of pivot joints, each pivot joint on a respective one of the legs; and at least one latch mechanism configured to selectively engage at least one of the slider joints with its respective leg, wherein each cross member is mounted to the respective adjacent legs by the slider joint on a first of the respective adjacent legs and by the pivot joint on a second of the respective adjacent legs.
Another aspect of the present invention relates to a playard, the playard comprising a collapsible frame structure which comprises a plurality of legs; a plurality of cross members arranged so that at least one cross member extends between, and is pivotally connected to, respective adjacent legs to form a side of the playard; a plurality of slider joints, each slider joint slidingly engaging a respective one of the legs; a plurality of pivot joints, each pivot joint on a respective one of the legs; and at least one latch mechanism configured to selectively engage at least one of the slider joints with its respective leg, wherein each cross member is mounted to the respective adjacent legs by the slider joint on a first of the respective adjacent legs and by the pivot joint on a second of the respective adjacent legs; and a fabric enclosure mounted to and supported by the collapsible frame structure.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate several embodiments of the invention and, together with the description, serve to explain the principles of the invention.
Reference will now be made in detail to presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. An effort has been made to use the same reference numbers throughout the drawings to refer to the same or like parts.
The playard 10 is illustrated in
The enclosure 14 may be removed from the collapsible frame structure 12 and washed and cleaned. The enclosure 14 may contain a door or opening (not shown) to allow a child ingress into and egress out of the playard 10. The enclosure 14 may also include a number of windows 16, which are transparent or semitransparent, so that a child can see outside of the enclosure 14 through the windows 16. The windows 16 may comprise, for example, cloth that is thin and porous enough to be transparent or semitransparent, plastic, webbing, or mesh.
The collapsible frame structure 12 may be collapsed with or without the enclosure 14 attached. Thus, the collapsible frame structure 12 provides flexibility in not necessarily requiring that the enclosure 14 be detached prior to collapsing the collapsible frame structure 12.
Moreover, the collapsible frame structure 12 may be embodied in any size as desired. Thus, a large playard may be employed for outdoor use, while a smaller playard may be appropriate for indoor use. The collapsible nature of the frame structure 12 allows for ready transport of a playard of any size, even a larger playard.
The collapsible frame structure 12 will now be described with respect to
Each of the legs 18 may comprise a hollow tube and may be made of plastic, metal, such as steel or aluminum, or any other suitable material. Hollow legs 18 are preferred because of their lightweight nature. This provides an advantage when the collapsible frame structure 12 is arranged in the folded arrangement and is carried, thus making the collapsible frame 12, and the playard 10, readily portable. The playard 10 has at least three legs 18, but it can have more, for example six, as shown in FIG. 2. The number of sides of the structure 12 generally is the same as the number of legs. The structure 12 may also be prismatic in shape.
The collapsible frame structure 12 may also include a plurality of feet 20, where each foot 20 is attached to and supports a respective one of the legs 18. The feet 20 may comprise metal, such as steel or aluminum, or plastic.
The collapsible frame structure 12 includes a plurality of cross members 22 arranged and extending, respectively, between adjacent legs 18. Like the legs 18, the cross members 22 may comprise hollow tubes and may be made of plastic or metal, such as steel or aluminum, or any other suitable material. Cross members 22 comprising hollow tubes are preferred because of their lightweight nature.
The plurality of cross members 22 may be arranged in pairs, where each pair of cross members 22 extends between respective adjacent legs 18. Each pair of cross members 22 may be arranged in an X-shape. In addition, each pair of cross members may be pivotally connected at pivots P so that, when the frame structure 12 is collapsed to the folded arrangement, the cross members 22 can pivot relative to each other.
The collapsible frame structure 12 includes a plurality of pivot joints. The pivot joints function to allow the cross members 22 to pivot relative to the legs 18. In this regard, the pivot joints may simply comprise pins to attach the cross members 22 to the legs 18. Another exemplary pivot joint 24 is illustrated in
The collapsible frame structure 12 also includes a plurality of slider joints. The slider joints function to allow an end of a respective cross member to slide up or down a respective leg to allow the frame to be opened or collapsed. Exemplary slider joints include, for example, slider joints 30, 40 as illustrated in
Each of the slider joints 30, 40 slidingly engages a respective one of the legs 18. For example, the leg 18 passes through hole 31, 41 in slider joints 30, 40, respectively. The slider joints 30, 40 also are pivotably attached to at least one adjacent cross member 22. In configurations where the cross members 22 are arranged in pairs, each of the slider joints 30, 40 may be pivotably attached to two adjacent cross members 22, such as shown in FIG. 2. That is, the end of the cross member can be pivotally secured in recesses 33, 43 of an appropriate slider joint 30, 40 by a pin (not shown) that passes through holes 35, 45 in respective walls 34, 44 and through the end of the cross member 22.
As explained above, the slider joints 30, 40 may slide along respective legs 18 so as to move the cross members 22, and hence the collapsible frame structure 12, between the folded arrangement and the fully open arrangement. In this respect, referring to
The legs 18 may have a curved shape, at least between the first and second positions P1, P2 so as to facilitate collapsing the collapsible frame structure 12 into its folded arrangement. The first position P1 and the second position P2 generally correspond to the folded arrangement and the open arrangement, respectively. Alternatively, the legs 18 may be completely straight or have some other shape.
The collapsible frame structure 12 also includes at least one latch mechanism 50. Each latch mechanism 50 is configured to selectively engage at least one of the slider joints 40 with a respective leg 18.
The collapsible nature of the collapsible frame structure 12 provides a frame with good portability. The compact fold of the frame structure 12 allows for the frame structure and playard 10 to be readily carried. In the fully open arrangement, the frame structure 12 along with the enclosure 14 provides a large play space.
Preferably the top rails 60 are flexible, thus reducing the number of steps required to fold or erect the playard 10. Each top rail 60 may comprise, for example, a strip of fabric material or webbing, which is taut in the open arrangement. Alternatively, each top rail 60 may comprise two stiff sections 62 and 64, respectively, with a fold mechanism 66 intermediate end portions 67 and 68 of the rail 60, separating the two stiff sections 62 and 64, so that the stiff sections may fold when the collapsible frame structure 12 collapses. The fold mechanism may comprise, for example, a hinge, a fold latch, or a simple pivot assembly. Examples of appropriate fold latches are disclosed in, for example, U.S. patent application Ser. No. 09/969,498 entitled “TOP RAIL LATCH FOR FOLDING PLAYARD” filed on Oct. 3, 2001 now abandoned, and published on Apr. 3, 2003 as PG publication No: US 2003/0061658 A1, which is hereby incorporated by reference.
Folding and unfolding the frame structure 12 is now explained with respect to

In a playard employing pivot joints 140, each top rail 60 can include top rail webbing 160 and top rail extensions 142 at either end of the webbing 160.
The top rail extensions 142 also include a flange 152. When the playard 10 is in the fully open arrangement, the flange 152 extends from a surface of the head portion 150 in a direction generally corresponding to the respective top rail 60, as shown in FIG. 18. The top rail webbing 160 can be secured to pin 143 or to the top rail extension 142. For example, an end of the top rail webbing 160 can be looped around pin 143 and then sewn, or otherwise secured, to a remainder of the webbing 160. Alternatively, the head portion 150 can include a hollow shaft (not shown) that extends between holes 154 to receive pin 143, and an end of the top rail webbing 160 can be looped around the shaft and then sewn, or otherwise secured, to a remainder of the webbing 160. In another arrangement, the end of the top rail webbing 160 can be sewn or otherwise secured directly to the head portion 150 or to the flange 152 of the extension 142. For example, the flange 152 can include a slot (not shown) therethrough that extends from its upper surface to its lower surface, and an end of the top rail webbing 160 can be threaded through and wound around the slot and sewn to a remainder of the webbing 160. In this manner, the top rail webbing 160 can be secured directly to the flange 152 of the top rail extension 142.
