Description
- None
- The present invention relates generally to play yards for confining infants, often called play pens; however, the teachings herein, while made in the context of a play yard, may also be applied to other similar structures such as beds and bassinets. The term “play yard” is intended to encompass all such structures. These structures generally include a lightweight frame and a soft covering, usually of open mesh fabric so that an infant can be viewed when in the play yard. The frame must be lightweight yet sturdy and safe when it is in a deployed configuration for use as a play yard and when it is in a folded or collapsed configuration for convenient storage. The individual frame members may be manufactured of metal, of high modulus fiber reinforced plastic resin, wood or other similar materials and the individual frame members may have any suitable cross sectional configuration such as solid sections, tubing, channels or rails. As used herein, the terms “vertical” and “horizontal” are approximate terms used for convenience to indicate general directions including those slightly off of true vertical and true horizontal.
- It is highly desirable to be able to fold a play yard for storage essentially by a one hand operation. Some play yards require two hands to unlatch a latch which maintains separate sections of the frame members in alignment when the frame is deployed or to relatively rotate sections of the frame about an axis on which they are generally aligned to unlock a hinge connecting them so that the play yard can be folded for storage.
- One example is U.S. Pat. No. 4,811,437 issued Mar. 14, 1989 to Dillner et al. which discloses latches centrally positioned in each of the top frame rails with which one hand must be sequentially used to fold the top rails. In one embodiment, the user must squeeze and move a latch release upwardly to allow the end sections of the various top rails to pivot downwardly toward the user's hand when releasing the latch. In another embodiment, rotatable tubing sections must be grasped and turned to release the latch. In each instance, numerous operations are required to release all of the latches in the top rails.
- An improved play yard frame structure is therefore desired which may be collapsed for storage primarily by the use of one operation.
- The folding play yard disclosed herein includes a generally horizontal upper frame comprised of upper side members, upper end members and upper corner connectors to which the side members and said end members are pivotally connected. Each of the upper side members and upper end members includes end sections pivotally connected to a latch for maintaining the end sections in horizontal alignment. The play yard also includes a generally horizontal lower frame comprised of a vertically moveable central release mechanism and diagonal braces extending from the central release mechanism to vertically extending members. The lower frame may also include lower side members each having end sections connected to a central hinge. The play yard also includes vertically extending members joining ends of the diagonal braces to the upper corner connectors and latch release means connected to the latches. The latch release means extends from the latches to moveable anchors carried by said vertically extending members, whereby upward movement of the central release mechanism causes movement of the anchors to tension the latch release means and release the latches for folding.
- The anchors may comprise bosses slidably mounted for vertical movement along guide tracks in the vertically extending members, the end sections of the lower side members being pivotally connected to the vertically extending members and engaging the bosses during pivotal movement of the lower side members relative to the vertically extending members to tension the latch release means to release the latches.
- A presently preferred embodiment of the invention will now be described with reference to the accompanying drawings, not to scale.

FIGS. 1 and 2 best illustrate afolding play yard 10 which, when deployed as seen inFIG. 1 , is comprised of a generally horizontal rectangularupper frame 20 havingupper side members upper end members upper corner connectors upper side members upper end members - The play yard also includes a generally horizontal
lower frame 50 which is comprised of a vertically movablecentral release mechanism 60 pivotally connected to fourdiagonal braces release mechanism 60. The lower frame may also include a pair oflower side members central hinge 56. The diagonal braces may comprise rigid structural shapes such as tubes. Vertically extendingmembers lower side members upper side members upper end members FIG. 1 astension springs 38; however, primarily for safety reasons, internally concealed torsion springs, not shown, will ordinarily be used for this purpose. - The latches 40-46 all being the same, only one (44) will be described with reference to
FIGS. 5 and 6 . Each latch is comprised of an invertedU-shaped support 402 having spacedparallel sides support 402 is preferably fabricated of metal or any other suitably rigid material. The two separate sections of anupper side member 24 are connected to the support on opposite sides of thesupport 402 by pins, axles or any other suitable connection for pivotal movement about spaced horizontal axes A and B. Torsion springs, not shown, are preferably connected to the end sections and to thesupport 402 on the axes A and B to bias the end sections of the supper side member in the directions indicated by the arrows to assist in folding the play yard. It will be seen fromFIG. 5 that thetop 408 of thesupport 402 engages the upper edge of the ends of the sections ofmember 24 to prevent upward movement of the latch when the latch is locked to maintain the play yard in the deployed configuration. Thelatch 44 has a pair oflevers sides support 402 for pivotal movement about spaced horizontal axes D, E. In the embodiment shown, the upperfirst ends 414, 416 of the levers are spring biased into engagement with the ends of the end sections of theupper side member 24 of the frame to maintain the play yard in a stable deployed configuration. A lowersecond end 418 of at least one of thelevers 412 is connected to one (94) of latch release means 90-96 such as tension cables, cords, wires or straps, 90-96 for pivoting thelever 412 in a counter clockwise direction (as seen inFIG. 5 ) about its axis D to move the upper first end 416 of thelever 412 out of engagement with the end of theupper side member 24 to release the latch. Acompression spring 422 may be deployed between the upperfirst ends 414 and 416 of thelevers first ends 414, 416 of the levers into engagement with the ends of the end sections of the upper side or end members of theupper frame 20. - The levers are engageable with each other such that pivotal movement of one (412) of the levers about its pivot axis (D) in a first (counterclockwise in
FIG. 5 ) direction caused by tensioning the associated latch release means causes the other (410) one of the levers to pivot in a second (clockwise) direction about its pivot axis (E) to release said latch. Both of the levers include aguide slot 426 which receives apin 422 affixed to the other lever such that movement of one of the levers about its pivot axis in a first direction caused by tensioning the latch release means (94 inFIG. 5 ) causes the other one of the levers to pivot in a second opposite rotational direction about its pivot axis E to release the latch unfolding the play yard. At least onecable guide 430 may be provided extending between and supported by the spacedsides support 402 for receiving the latch release means 94 comprising a wire or cable and, optionally, a cable sheath S (FIG. 6 ). Asecond cable guide 432 may also be provided as shown and, optionally,additional compression springs second ends 418, 420 of the levers and the associatedcable guide FIG. 5 shows thelower springs FIG. 6 for comparison.

Theside members 52 may each have aplug 53 inserted into the end, the plug having alatch lip 55.Anchors 100 for the latch release means are provided in the form of slidably mountedbosses 850 which are mounted in the feet 85-88 for vertical movement along guide tracks 852 formed in the feet 85-88. Afastener 102 is affixed to the lower end of each latch release means 90 and engages the lower surface of theboss 850. Tension on the latch release means urges theboss 850 upwardly in thetrack 852 against a stop in the form of the underside of thelip 55 at the end of thelower side members 52. The end sections of thelower side members 52 are maintained in generally horizontal alignment by thehinges 56 when the play yard is in its deployed configuration. Cable guides 81, similar to the cable guides 430, 432 described above, may be fabricated in thefeet 85 and sized appropriately to receive a cable sheath S if provided. - The latch release means 90-96 are connected at their respective upper ends to one of the latches 40-46 and extend from the latches along the end sections of the upper members 22-28, thence along the upper corner connectors 30-36 where the latch release means are bent to extend downwardly along the vertically extending members 80-84 to the
anchors 100. - As best seen in
FIGS. 1 and 2 , to collapse and fold the play yard from its deployed position to its storage position, the user may simply use a single hand to pull upwardly on a graspingloop 62 or a handle which extends upwardly through an aperture in the floor panel (not shown) of the play yard such that upward movement of therelease mechanism 60 and attached ends of the diagonal braces 70-76 pulls the end sections of thelower side members release mechanism 60. As the lower side members fold upwardly at thehinges 56 thelips 55 downwardly move thebosses 850 to tension the latch release means 90-96 and essentially simultaneously release each of the latches 40-46 permitting the end sections of theupper side members upper end members lower side members lower side members loop 62 permits the play yard to fold to the intermediate position shown inFIG. 2 and thence to a fully collapsed configuration for convenient storage.
