Abstract
A play yard has an oval-shaped upper frame. The upper frame is made of two u-shaped tubes and is supported by two vertical posts at either end of the play yard. The ends of each of the u-shaped tubes of the upper frame are connected to each post so as to be able to rotate about the posts. Located on each post is a slider which can slide up and down the post. Each slider is held in place by a button on each post. Diagonal support braces connect the sliders to each of the u-shaped tubes of the upper frame. When the play yard is in use, the upper frame is supported by the two vertical posts and the diagonal support braces located on either side of the play yard. The lower end of each post is connected to two opposing cantilevered legs at a hub. Each of the legs is substantially u-shaped and is pivotally connected at the hub in order to be able to rotate about the posts.
Description




BACKGROUND OF THE INVENTION




This invention relates to a collapsible play yard. One common design approach is exemplified by U.S. Pat. No. 5,485,655 to Wang. The disclosed play yard has a rectangular upper frame formed of eight frame members pivoted together at their ends, with two members defining each of the four sides of the upper frame. A hinge lock rotationally fixes the two members on each side with respect to each other in a coaxial relationship. The upper frame is supported at its corners on the upper ends of four vertical posts. A rectangular lower frame, also formed with eight hinged frame members, is coupled to the lower ends of the vertical posts. The lower frame supports a segmented rigid floor assembly, and fabric side wall panels are stretched between the upper and lower frame assemblies and the vertical posts. The posts contact a supporting surface (floor or ground), supporting the play yard. The play yard can be collapsed from its deployed configuration to a stored configuration by releasing the hinge locks on the upper frame members, allowing the sides of the upper frame to fold downwardly in a u-shape. The lower frame members are similarly folded upwardly, and the vertical posts urged radially toward each other and the center of the play yard. The play yard folds into a rectangular package with a height defined by the height of the vertical posts.




U.S. Pat. No. 5,867,851 to Mariol discloses a similar play yard frame, except that the upper and lower frames are triangular and there are accordingly three vertical posts.




Play yards similar to the one disclosed in U.S. Pat. No. 5,485,655 have gained wide acceptance in the market place. However, they suffer from some drawbacks. The frames have many parts, making them more difficult and costly to manufacture. The operation of the frame is complicated, requiring the user to independently release four hinge locks on the upper frame and urge the vertical posts manually. The u-shaped fold of the upper frame sides poses a risk of inadvertent collapse of the frame if the child occupant (or a sibling or parent outside the play yard) bears down on the upper frame. There have been reported incidents of children being entrapped in a collapsed upper frame rail. The hinge locks are therefore the subject of much design attention to reduce the risk that they will inadvertently release. One result is that the hinge locks are often difficult and/or non-intuitive to operate. They are often concealed within a fabric sleeve enclosing the upper frame rail, making it even more difficult to discern their operation.




Another common approach to a play yard frame is exemplified by U.S. Pat. No. 3,063,065 to Shaw. The disclosed frame includes two u-shaped upper frame members pivoted to the apex of a triangular vertical support structure. The support structure includes on each side of the frame a central vertical post and a pair of downwardly and outwardly diverging legs. A pair of articulated links are pivoted to the upper frame sides and to the vertical post to support the upper frame. To collapse the frame, the linkages are folded, and the upper frame members rotated downwardly about the vertical support structure. The legs are also pivoted toward the post, producing a relatively flat rectangular folded configuration.




The frame design disclosed in U.S. Pat. No. 3,063,065 also suffers from drawbacks, including a relatively complex fold, and relatively large folded dimensions that are dictated in part by the length of the diagonal legs.




Existing play yard designs, including the designs described above, are typically fairly rigid structures intended not to move or shift when the infant occupant moves about in the play yard. A child occupant is therefore simply confined within the play yard, and derives little play value from the play yard itself.




SUMMARY OF THE INVENTION




The present invention is able to overcome some of the shortcomings of other play yards through a combination of unique design features. One such example is a play yard having an oval-shaped upper frame. The upper frame is made of two u-shaped tubes and is supported by two vertical posts at either end of the play yard. The ends of each of the u-shaped tubes of the upper frame are connected to each post so as to be able to rotate about the posts. Located on each post is a slider which can slide up and down the post. Each slider is held in place by a button on each post. Diagonal support braces connect the sliders to each of the u-shaped tubes of the upper frame. When the play yard is in use, the upper frame is thus supported by two vertical posts and the diagonal support braces located on either side of the play yard. The lower end of each post is connected to two opposing cantilevered legs at a hub. Each of the legs is substantially u-shaped and is pivotally connected at the hub in order to be able to rotate about the posts. The legs each have pairs of foot pads and foot stabilizers.




The play yard may be folded into a planar-like shape by pressing the buttons associated with the sliders and moving the sliders downwardly. Doing so allows for the upper frame to collapse towards the two posts. Similarly, the legs are folded upwardly towards the post. Both the upper frame and the legs are continually folded until the play yard reaches a planar-like configuration.




These design features, among others, help the present play yard achieve a number of advantages. The disclosed play yard has a frame design where inadvertent collapse has been minimized. A stable frame has also been provided to eliminate the risk that the play yard will slip and tip over. The play yard is both comfortable and entertaining for the child. One such entertaining feature is that the play yard may bounce slightly as the child moves about in the play yard. The play yard is also very convenient for parents. It can be used indoors or outdoors and is very easy to collapse, store, and transport.

DETAILED DESCRIPTION OF THE INVENTION




The following is a description of the preferred embodiments of the invention.





FIGS. 1 and 2

are front perspective views of a collapsible play yard


20


in its deployed position. As seen in

FIG. 1

, a zip-up dome canopy


30


may be attached to the play yard


20


. The canopy


30


, like the play yard


20


, is collapsible, and as is seen in

FIG. 2

falls to the outside of the edge of the upper portion of the deployed play yard


20


when it is not in use.




with reference to

FIG. 2

, the side of the play yard


20


is formed from an oval-shaped wall


40


having opaque portions


42


and transparent portions


44


. The opaque portions


42


and transparent portions


44


may be made of, respectively, nylon and mesh. The nylon portions


42


in

FIG. 2

are along the ends of the wall


40


, with the mesh portions


44


located in between the nylon portions


42


. It should be recognized that there are many possible arrangements for the opaque


42


and transparent


44


portions other than disclosed in FIG.


2


. For instance, one half of the wall


40


could be formed solely of an opaque portion


42


, while the other half could be formed solely of a transparent portion


44


. It is also possible to attach an opaque material that is capable of folding to the top of the wall


40


at points adjacent to the transparent portions


44


. Such an arrangement would allow for the transparent portions


44


to be selectively covered or uncovered.




The play yard


20


also has a floor


50


. The floor


50


is suspended to the wall


40


by sewing the nylon outside portion of the floor


50


to the wall


40


. In

FIG. 2

, the floor


50


is oval-shaped and is created by placing an oval-shaped pad on top of the outside portion of the floor


50


. The pad is made by capturing three sections of approximately 5 mm. ({fraction (3/16 )} inch) thick hardboard (two half circles and one center section) between two layers of nylon, and by placing an approximately 19 mm. ({fraction (3/4 )} inch) piece of foam on top of the hardboard and below the top layer of nylon. For cleanliness purposes, a removable sheet may be placed on top of the floor


50


.




The frame


60


of the play yard


20


is disclosed in FIG.


3


. The upper frame, a section of which is shown more particularly in

FIG. 4

, includes two upper frame members


70




a


and


70




b.


The upper frame members


70




a


and


70




b


may be u-shaped and formed of approximately 19 mm. ({fraction (3/4 )} inch) diameter steel tubing. These u-shaped frame members are ultimately placed in a nylon, padded tunnel formed at the top of the wall


40


, and hence act to support the wall


40


and floor


50


, which hang from the upper frame members


70




a


and


70




b.


In the alternative, the upper frame could be formed of single or multiple frame members of various sizes and shapes. For instance, a single u-shaped or oval-shaped tube could be utilized to form an asymmetrically-shaped play yard.




The upper frame members


70




a


and


70




b


are coupled to a pair of posts


80


at upper hubs


90


, which help support the upper frame members


70




a


and


70




b.


The posts


80


disclosed in

FIG. 3

are vertically oriented. The upper hubs


90


shown in

FIGS. 3 and 4

include pivot points


92


where the upper hubs


90


connect to the upper frame members


70




a


and


70




b.


The posts


80


connect to the upper hubs


90


at points


94


. The upper hubs


90


each form a pair of back-to-back devices into which upper frame members


70




a


and


70




b


are fitted. They may be made of nylon (or other plastic) or elastomeric material. The posts


80


can be formed of approximately 22 mm. ({fraction (7/8 )} inch) diameter steel or other material of similar strength, and together in combination with a lower u-shaped member


82


, form a single extended u-shaped member


84


that is the center axis of the play yard


20


. Note that each post


80


may be formed by mechanically connecting portions of the post


80


to one another to form a single post


80


. Alternatively, each post


80


could be an integral structure such that the extended u-shaped member


84


could be a single unitary structure having no mechanical connections. The advantage of having mechanically connected posts


80


is that the play yard can be sold in a smaller package size due to portions of the posts


80


being divided from one another in the packaging. However, such an arrangement requires the consumer to assemble the extended u-shaped member


84


.




In addition to being supported at their proximal ends by the upper hubs


90


connected to the posts


80


, upper frame members


70




a


and


70




b


are also supported at intermediate pivot points


114


by support members


100


. Support members


100


, which are shown in

FIGS. 3 and 4

as diagonal braces, are pivotally connected to sliders


110


that slide up and down the posts


80


. The slider


110


shown in

FIGS. 4 and 5

can be made of nylon or other suitable material. The support members


100


are pivotally connected to sliders


110


at points


112


. When the upper members


100


are in deployed states, each slider


110


locks into position through the use of a release mechanism


116


, which functions to both engage and disengage the sliders


110


from its locked position on post


80


.

FIG. 3

shows that when the play yard is placed on the ground in this deployed state, the posts


80


are preferably substantially vertical to the ground, and the upper frame members


70




a


and


70




b


are preferably held in a horizontal position. Note that the release mechanism


116


disclosed in

FIGS. 4 and 6

is a button, such as those sold under the trademark “VALCO,” but other types of release mechanisms


116


, such as a latch, could be used to hold each slider


110


in place. Similarly, other structures than that disclosed in

FIG. 5

could be used as a slider


110


that is capable of sliding up and down post


80


.




Each post is coupled to a ground-engaging base of the play yard


20


. In particular, a lower hub


120


is connected to each post


80


at the lower end of each post


80


, such lower end being at or near the extreme bottom of the post


80


. The type of hub


120


disclosed in

FIG. 3

is a nylon housing assembly


120


that is formed from an outer


121


and an inner


122


housing assembly. The outer and inner housing assemblies


121


,


122


, define lower


123


, central


124


, and upper grooves


125


. Central groove


124


is offset relative to lower groove


123


and upper groove


125


to provide a detent feature as will be described below. Each inner housing assembly


122


may have two small tabs coupled to its inside and located below floor


50


to help support the floor


50


.




The housing assembly


120


also serves as a hub and fulcrum point for two opposed cantilevered legs


130


. As seen in

FIGS. 2 and 3

, when the play yard


20


is in its deployed state, the ends of the legs


130


, which are pivotally connected to the hub


120


, are located in the lower grooves


123


of the two lower hubs


120


. The offset of grooves


123


relative to central groove


124


in hub


120


acts as a first detent, locking the legs


130


in the deployed position. The legs


130


can be deflected outwardly away from each other to move them from the first detent in groove


123


and then slid along central groove


124


in hub


120


until they spring back into upper grooves


125


, which form a second detent, locking the legs


130


in a folded position. Each leg


130


is substantially u-shaped and can be made of approximately 12 mm. ({fraction (1/2 )} inch) diameter steel substantially u-shaped tubes


132


. The tubes


132


have approximately 457 mm. (18 inch) long sections of approximately 10 mm. ({fraction (3/8 )} inch) diameter spring steel


134


mechanically fastened to each end (partially inside the tube), forming the resultant leg


130


. The deflection of the spring steel


134


ends of the legs


130


helps create a bounce-effect for the frame of the play yard


20


. In order to provide more support for the outer ends of the play yard


20


, the disclosed legs


130


each have an offset bend


136


in the center. The legs


130


disclosed in

FIG. 3

could thus be described as w-shaped in addition to substantially u-shaped. Note that the offset bend


136


is not a necessary feature, and can be more or less pronounced, or eliminated entirely (such that the legs


130


more closely resemble a perfectly u-shaped structure). Note also that, as is the case with the upper frame, the legs


130


can be formed of single or multiple frame members of various sizes and shapes. So, for instance, a single substantially u-shaped or oval shaped tube could be utilized to form an asymmetrically-shaped play yard


120


.




For additional stabilization of the play yard


20


, each leg


130


can also be equipped with pairs of foot stabilizers


137


and foot pads


138


. The foot stabilizers


137


are mechanically attached near each corner of each leg


130


and help prevent the play yard


20


from tipping by providing additional contact points between the legs


130


and the ground. Pairs of foot pads


138


, which can be made of thermal plastic elastomer, are mechanically attached to each leg


130


at the points where the legs


130


come into contact with the ground. The pads


138


help stabilize the legs


130


by providing slip resistance for the product. Rollers or wheels could also be attached to the legs


130


.




The above-described play yard


20


provides a comfortable and entertaining play space for children. The large enclosure of the play yard


20


gives the child plenty of room to rest and play. Additionally, the mesh and opaque portions of the play yard


20


and canopy


30


allow for the circulation of air and elimination of annoying sunlight and bugs. For added enjoyment, toys can be attached or built-in to the inside of the wall


40


of the play yard


20


, and the inside of the wall


40


can be printed with colorful patterns and drawings. Multiple toys can be sewn-on to the wall


40


, and can include soft toy animals, each with a different toy feature such as a squeaker, a rattle, a mirror, and a crinkle sound.




Additional entertainment value is derived from the frame design, which allows the play yard


20


to bounce as the child moves about the play yard


20


. The bounce produced by the play yard


20


depends on many factors, including the length, thickness, and type of materials used to construct the frame. The disclosed play yard


20


is generally designed for children up to 30 pounds. However, the design of, and materials used to construct, the frame could easily be modified so as to allow for a person of greater weight without compromising the features of invention. Preferably, at no time should the floor


50


of the deployed play yard


20


come into contact with the ground. Hence, because the play yard


20


is designed for children up to 30 pounds, the floor


50


of the play yard


20


should be resting on the supports of the legs


130


even when a weight of 30 pounds is placed on an extreme end of the floor


50


. Similarly, the lower hubs


120


should not hit the ground until a weight of 40 pounds is placed on the floor


50


. It should be recognized of course that if desired one could make some relatively simple modifications to the frame structure of the play yard


20


so that the lower hubs


120


and the floor


50


touch the ground at a lesser weight (or no weight at all). Such modifications may decrease the bounce produced by the play yard


20


.




Besides being entertaining for children, the play yard


20


is very convenient for parents. It can be used both indoors and outdoors, and is collapsed very easily and compactly for transportation and storage purposes. The steps required to collapse the deployed play yard


20


shown in

FIG. 1

are easily followed. If closed, the canopy


30


attached to play yard


20


needs to be opened and allowed to fall to the upper outside edge of the wall


40


, as disclosed in FIG.


2


. The release mechanisms


116


, which in this case are buttons, are activated and the sliders


110


moved down the two posts


80


, allowing the upper frame members


70




a


and


70




b


to pivot about pivot points


92


. As the sliders


110


move down the posts


80


and the upper frame members


70




a


and


70




b


pivot, the ends of the members


70




a


and


70




b


farthest from the post (the distal ends) move down and towards the posts


80


. Note that once the release mechanism


116


is activated, the upper frame members


70




a


and


70




b


can be moved by either applying force directly on the sliders


110


or directly on the members


70




a


and


70




b.


As described above, the legs


130


are collapsed by initially slipping the ends of the legs


130


out of the lower grooves


123


of each hub


120


. The legs


130


are then moved upwardly, and in doing so the ends of the legs


130


farthest from the post (the distal ends) move upwardly and towards the posts


80


. The floor


50


folds in the same direction as the legs


130


. If desired, the play yard


20


can be collapsed by performing the above-described steps in varying order. For instance, one could easily begin the collapsing process by first beginning to fold the legs


30


, and next by releasing the release mechanism


116


.




The ends of the upper frame members


70




a


and


70




b,


the legs


130


, and the floor


50


are folded until reaching the position disclosed in

FIGS. 7 and 8

. In this position, the play yard


20


assumes a compact, planar-like configuration that enables it to be easily transported and stored. As seen in

FIGS. 7 and 8

, when the play yard


20


is completely collapsed, the sliders


110


are located at or near the top of the lower hubs


120


; the upper frame members


70




a


and


70




b


are folded between the posts


80


and the floor


50


such that a portion of each of the upper frame members


70




a


and


70




b


is substantially parallel to the posts


80


; and the ends of the legs


130


have moved through the central grooves


124


and are held in place by the upper grooves


125


of the hubs


120


. With reference to

FIG. 7

, straps


140


with VELCRO surfaces can be secured to the bottom outer surface of each end of the floor


50


so as to ensure the floor


50


remains folded after the play yard is collapsed. As seen in

FIG. 8

, the offset bends


136


of each leg


130


approach one another and act as a handle for carrying the collapsed play yard


20


. In order to more easily utilize this handle feature, the folded play yard


20


in

FIG. 7

could be altered so that the offset bends


136


of the legs


130


lie above the ends of the floor


50


. This allows the offset bends


136


to come into closer proximity to one another so as to make it easier to grasp the handle formed by the bends


136


. In the event the distal ends of each leg


130


are not positioned in close enough proximity to act as a handle, carry handles could be added to the folded play yard


20


. The handles could be attached to the bottom of each end of the floor


50


such that when the play yard is folded, each handle is lifted up and around the ends of the legs


130


to carry the play yard


20


. Note that in order to unfold the legs


130


, a force needs to be applied to remove the legs from the upper grooves


125


. A spring can be attached to the inside of each hub


120


so that, after removing the legs from the upper grooves


125


, the ends of the legs


130


automatically spring into lower grooves


123


.




It will be apparent to one of ordinary skill in the art that the invention is not limited to the exact details of construction, design, and operation described above, as modifications can be made to the disclosed structure without departing from the spirit and scope of the invention. Accordingly, the invention is only limited by the appended claims.
