referring now to the drawings , and with particular reference to fig1 , a bassinet constructed in accordance with the teachings of the invention is generally depicted by reference numeral 20 . as shown therein , the bassinet 20 includes a sleeping basket 22 supported by a foldable stand 24 . as will be discussed in further detail herein , the bassinet 20 is foldable from the deployed or erected position shown in fig1 - 5 , to the stowed or folded position shown in fig6 . when in the deployed position , the bassinet 20 provides a stable and sturdy sleeping basket 22 , and when in the stowed position , the bassinet 20 forms a compact structure for ease of storage and transportation purposes . referring again to fig1 , and with additonal reference to fig2 - 5 , the basket 22 is shown having a floor 26 from which a flexible side 28 upwardly extends to define an oblong - shaped enclosure , with an open top 30 . the flexible side 28 is depicted as one continuous expanse of material having four identifiable sides , but could be provided in multiple sections without departing from the scope and spirit of the invention . as shown best in fig3 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 fig7 and 8 , includes first and second leaves 44 and 46 connected at a pivot 48 . each leaf 44 and 46 includes an elongated base 50 and a raised ledge 52 . the elongated base 50 and raised ledge 52 are provided normal to each other . the second leaf 46 includes a bearing surface 54 at a comer 56 thereof . a pivot rod 58 , connected to the first leaf 44 , matingly fits within the bearing surface 54 to allow for pivotal motion . as shown in fig7 and 8 , and described in further detail herein , it can be seen that the hinge 42 is able to pivot downwardly about pivot 48 from the deployed position shown in fig7 to the stowed position shown in fig8 . however , the contact between the adjacent raised ledges 52 , and the location of the pivot 48 on a bottom surface 60 of the hinge 42 prevents the hinge 42 from being pivoted upwardly about the pivot 48 , the significance of which will be discussed in further detail herein . referring now to fig2 , the illustrated stand 24 has a frame or top member 62 to which first and second rims 64 , 66 ( shown in phantom ) are pivotally attached at pivots 68 . 70 , respectively . first and second legs 72 , 74 are also pivotally attached to the frame 62 , at separate pivots 76 , 78 , respectively ( also shown in phantom ). each of the first and second rims 64 , 66 and first and second legs 72 , 74 are substantially u - shaped in the depicted bassinet 20 . however , persons of ordinary skill in the art will appreciate that other shapes are possible , particularly with regard to first and second legs 72 , 74 , wherein four individual legs could be provided as opposed to the two legs depicted without departing from the scope or spirit of the invention . supporting cross - bars 79 , 80 may laterally span the u - shaped legs 72 , 74 to provide added structural support . when the stand 24 is folded from the deployed position shown in fig1 - 5 to the stowed position shown in fig6 , each of the first and second rims 64 , 66 , and first and second legs 72 , 74 are substantially parallel to one another with the flexible sidewall 28 being collapsed inwardly . in so doing , the resulting width a of the bassinet 20 is minimized and limited to the relatively short expanse of material provided by the frame 62 . accordingly , in the stowed position , the bassinet 20 can be easily transported and / or stored in multiple areas , including beneath a bed , or within a trunk space , for example . in order to temporarily lock the stand 24 in the deployed position shown in fig1 , and to thereby secure the floor 26 in a horizontal plane , a plurality of tension bars 81 are provided . in the depicted embodiment , four such tension bars 81 are provided , two of which connect the first rim 64 to the first leg 72 , and two of which connect the second rim 66 to the second leg 74 . referring specifically to fig2 , the tension bars 81 are shown in detail . each includes first and second links 82 , 84 , which are pivotally connected to a locking clip 86 . as can be seen from fig3 and 4 , each locking clip 86 is channel - shaped and includes a closed side 88 from which first and second lateral sides 90 , 92 extend . an open space 94 is provided opposite the closed side 88 and allows the pivot links 82 , 84 to pass therethrough . such tension bars 81 are of a conventional design , common on such devices as foldable card tables and the like , and are often referred to as over - center locks . 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 fig6 to the deployed position of fig1 - 5 , the user must exert substantial force on the locking clip 86 to force the corresponding tension bar past the center line β . this in turn flexes the rims and legs away from each other to allow for the locking clip 86 to pass over - center . the tension bar 80 is locked in place by engagement of sides 96 , 98 of the pivot links 82 , 84 , respectively , with the closed sides 88 of the locking clips 86 . in so doing , the locking clips 86 are prevented from further outward motion slightly past the center line β , and the stand 24 is temporarily locked into the deployed position . in order to move or transform the stand 24 back into the stowed position the user must exert sufficient force in the direction of arrow γ ( see fig2 ) to pivot the tension bars 80 inwardly . when the tension bars 81 are in the locked positions shown in fig1 - 5 , the tension generated thereby is transferred through the stand 24 such that the first and second rims 64 , 66 are located in planes which are substantially horizontal to ground . since the flexible sidewall 28 is connected to the first and second rims 64 , 66 , and to the first and second floor halves 38 , 40 , this tension is also transferred through the flexible side 28 to the floor 26 to hold the floor horizontal to ground as well . the flexible sidewall 28 is sized to barely stretch between the floor 26 and the first and second rims 64 , 66 when in the deployed position to facilitate this tension transfer . 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 fig2 . 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 fig1 and 3 , a protective upper shield 110 may be provided proximate the first and second rims 64 and 66 and be partially removable therefrom via a suitable fastener , such as a zipper 112 . when the upper shield 110 is secured to the first and second rims 64 , 66 via the zipper 112 , the upper shield 110 is horizontal to the floor 26 and provides an enclosed crib space 114 . the protective shield 110 is preferably manufactured from a mesh - like material to allow for communication between the crib space 114 and ambient air . the flexible sidewall 28 is preferably manufactured from a similar mesh material . to secure the flexible sidewall 28 to the first and second rims 64 , 66 and the floor 26 , a solid fabric material may be employed . in operation , it can therefore be seen that the bassinet 20 can be easily transformed from the stowed position , shown in fig6 , to the deployed position , shown in fig2 , with limited effort by the user . more specifically , starting with fig6 , a user can simply pull upwardly and outwardly upon the first and second rims 64 , 66 at points δ . this motion in turn pulls the first and second rims 66 , 64 into a horizontal position parallel with the frame 62 . since the first and second rims 64 , 66 are attached to the tension bars 81 , which in turn are connected to the first and second legs 72 , 74 , the tension bars straighten and the legs are pulled apart to the position shown in fig2 . if , sufficient force is generated by such motion , the locking clips 86 may pass over - center and into the locked position . alternatively , once the stand 26 is in the deployed position , the user may need to apply additional force to the locking clips 86 to pass the clips 86 over - center and lock the bassinet 20 into the deployed position . when the bassinet 20 is to be placed back into the stowed position of fig6 , the user simply needs to apply sufficient force to the locking clips 86 in the opposite direction , which in turn collapses the first and second rims 64 , 66 downwardly and enables the first and second legs 72 , 74 to be folded inwardly into the parallel configuration of fig6 . the bassinet 20 can then be grasped , as by the frame 62 , or by the first and second legs 72 , 74 for easy transportation and storage purposes . 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 .
a foldable bassinet is disclosed . the bassinet can be transformed from an erected position wherein a floor of the bassinet is substantially horizontal to ground , and elevated therefrom by a stand , to a folded position wherein the bassinet is compacted into a relatively small size . using a uni - directional hinge in the floor of the bassinet , and a plurality of over - center locks , the floor of the bassinet can be locked into the horizontal position easily and effectively , without any structure provided directly below the center of the bassinet floor .
