The present invention generally relates to cribs and bassinets and, more particularly, relates to portable and foldable cribs and bassinets.
Bassinets have been used in the care of infants for centuries. Such devices typically include an oblong-shaped basket having a floor, raised walls, and an open top. A mattress and/or other suitable cushioning are typically provided within the basket for enhancing the comfort of the child. The basket is often provided on some form of stand to elevate the level of the basket for ease of use.
As families have become increasingly mobile, it has become increasingly desirable to provide a portable bassinet to accommodate this mobility. However, given the shape of the oblong basket, height of the supporting stand, and structural integrity and weight limitations required of such devices, bassinets do not easily lend themselves to transformation into dimensionally small and light weight units for ease of transportation and/or storage.
A number of foldable playpens and cribs have been created. However, to the extent such structures include a foldable floor, they typically rely on support afforded by the ground on which they rest to maintain a horizontal floor position. If elevated, the ground would provide no support, and the floor would tend to invert given a sufficiently heavy load. Alternatively, centralized support structure must be provided below the foldable floor. Such structure necessarily imposes undesirable size and weight penalties on the device.
In accordance with one aspect of the invention, a bassinet is provided which comprises a frame, a floor, and a flexible sidewall. The frame includes a top member with first and second legs and first and second rims pivotally attached thereto. The frame is foldable from an erected position wherein the rims are parallel to the top member to a folded position wherein the rims are non-parallel to the top member. The floor supported below the rims includes first and second halves connected by a hinge. The first and second halves are foldable downwardly about the hinge, but the hinge prevents folding of the first and second halves upwardly about the hinge. The flexible sidewall connects the first and second floor halves to the first and second rims, respectively. The first and second rims and the sidewalls prevent the first and second halves of the floor from being downwardly folded about the hinge when the frame is in the erected position.
In accordance with another aspect of the invention, a bassinet is provided which comprises a frame, and a foldable floor. The foldable floor is supported by the frame and connected by a center hinge. The center hinge is suspended without any structure directly therebelow.
In accordance with another aspect of the invention, a bassinet is provided which comprises a top member, first and second legs pivotally attached to the top member, first and second rims pivotally attached to the top member, first and second tension bars connecting the first leg to the first rim and the second leg to the second rim, respectively, a flexible wall extending downwardly from the first and second rims, a foldable floor supported in a substantially horizontal plane by the flexible wall below the first and second rims to define a crib space with the flexible wall, and a hinge connecting first and second halves of the foldable floor. The hinge also prevents upward folding of the floor, while the tension bars, rims, and flexible wall prevent downward folding of the floor.
These and other aspects and features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
While the invention is susceptible to various modifications and alternative constructions, certain illustrative embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the scope of this patent to the specific forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions and equivalents falling within the spirit and scope of the appended claims.
Referring now to the drawings, and with particular reference to
Referring again to
As shown best in FIGS. 3 and 7-8, the floor 26 includes a hardened sub-floor 32, on which a cushioned mattress material 34 having buttons 36 rests. The sub-floor 32 is provided in first and second halves 38, 40, which are connected by a unidirectional hinge 42. The hinge 42 can be provided in multiple portions, such as the two, laterally spaced, portions depicted.
Each portion of the hinge 42, as shown in detail in
Referring now to
When the stand 24 is folded from the deployed position shown in
In order to temporarily lock the stand 24 in the deployed position shown in
The combined length of the first and second links 82, 84 and locking clip 86 is slightly greater than the combined distance depicted by the center line β between adjacent rims and legs. Therefore, as the stand 24 is folded from the stowed position of
When the tension bars 81 are in the locked positions shown in
It can therefore be seen that the hinge 42, which prevents upward rotation past horizontal, and the tension bars 38, which prevent downward rotation past horizontal, cooperate to maintain and temporarily lock the floor 26 in a horizontal position when the bassinet 20 is in the deployed position. Such horizontal maintenance is provided without any structure whatsoever being provided directly below the hinge 42, or floor 26, as clearly shown in FIG. 2. Moreover, the hinge 42 cooperates with the floor 26 to provide a continuous, flat bottom surface for the sleeping basket 22, adding to the comfort of the infant when the bassinet 20 is in use.
As accessories to the bassinet 20, a storage basket or bay 100 is provided below the sleeping basket 22. The storage bay 100 is preferably manufactured from fabric to allow for necessary flexibility when moving from the stowed position to the deployed position. The storage bay 100 may include an arcuately shaped bottom 102 with first and second semi-circularly shaped sides 104 and 106. The storage bay 100 may be connected at each of the four resulting corners 108 to the first and second legs 72 and 74.
As shown in
In operation, it can therefore be seen that the bassinet 20 can be easily transformed from the stowed position, shown in
When the bassinet 20 is to be placed back into the stowed position of
From the foregoing, it can be seen that the disclosed bassinet can be easily transformed from a sturdy deployed position to a compact stowed position. In the deployed position, substantial structure is provided to ensure the bassinet is secured and stable, yet no structure is provided directly below the center of the bassinet floor. In the stowed position, the illustrated, bassinet occupies little space and is easily transported. Moreover, through such a design, the disclosed unit can be easily manufactured at relatively low cost and weight.
This application is a continuation of Ser. No. 09/563,139 filed May 2, 2000 now U.S. Pat. No. 6,588,033.
