FIELD OF THE INVENTION
This invention relates to bassinets and more particularly to bassinets which are selectively rockable.
BACKGROUND
Applicant's co-pending application, Ser. No. 10/103,580 filed Mar. 21, 2002, which is incorporated herein by reference as if fully set forth, discloses a bassinet mounted upon a selectively rockable support. The support includes rockable caster assemblies that may be lowered and locked into place for rolling movement to any desired location. The caster assemblies are selectively lockable to prevent movement of the support and to prevent rocking.
The support with the bassinet mounted thereon may further be attached to an adult bed to convert the bassinet into a bedside sleeper. The bassinet of Applicant's earlier application, is not rockable when separated from its support. It is desired to provide a bassinet that is a separate, independent and rockable bassinet when separated from its support.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
FIGS. 1 and 2 show a bassinet assembly 10 comprised of a support frame 20 and a bassinet 50. The support frame 20 comprises a pair of arcuate, members 21, 22 having respective caster housings 23-26 secured at their ends. Each housing has mounted therein a caster assembly moveable between a first position totally enclosed within the housing, enabling the support frame to rock, and a second extended position that permits rolling movement.
The caster assemblies and the mechanism for raising and lowering them as described in the aforementioned co-pending application, Ser. No. 10/103,580 are suitable for use in the present invention. However, other casters with locking and raising/lowering mechanism may be employed.
The housings 23-26 preferably extend beyond the ends of the arcuate tubular members to limit the degree to which the support frame may be tilted, thereby increasing the stability of the support frame.
The support frame has four uprights 27, 28, 29 and 30 that are preferably joined at their upper ends with the central portion CP to form inverted U-shaped members. Alternatively, as shown in FIG. 2, uprights 27-30 respectively may terminate in upper ends that are received within tubular openings 31a through 34a whereas the lower ends are telescoped into hollow cylindrical portions 23a, 24a, 25a and 26a of housing 23, 24, 25 and 26 respectively, as shown in both FIGS. 1 and 2. In place of the central portions CP of FIG. 1, the embodiment of FIG. 2 employs a pair of rails 35 and 36 that are secured within openings 31b-34b and vertically aligned openings 31b-34b of brackets 31-34. The cross rails 37 and 38 are each secured within horizontally aligned openings 31c-32c and 33c-34c. The rails 35, 36, 37 and 38 provide structural strength and rigidity to the support frame.
FIG. 1 illustrates only the bottom board 51 and framework 70 of the infant enclosure 20 (a bassinet in this illustrative embodiment) in order to better understand the features of the present invention. The bottom board 51 is a flat, sturdy board made of a suitable material for supporting an infant, such as plastic, wood or a composition board, for example. The frame 70 is comprised of supports 72 mounted upon board 51 and supporting loop-like rail 71 above the board 51. The swingably mounted curved struts support a hood (not shown). The rail 71 supports a fabric that surrounds the board 51. As shown in FIGS. 2 through 10, the underside of the board is provided with a pair of spaced, substantially parallel rocking members 52, 52 secured to the underside of board 51 by suitable fastening means, such as rivets or bolts, not shown for purposes of simplicity. Since the rocking members 52 are substantially identical in both design and function, only one of them will be described in detail. Making reference to FIG. 3, rocking member 52 has an upper surface 52a which is substantially flat and a bottom surface 52b which is arcuate at the intermediate portion between its end portions 52c, 52d, which are substantially parallel to bottom surface 52a. This parallel arrangement is preferred but not required to obtain the advantages of the invention. Arcuate surface 52b is configured to engage a support surface, such as a floor, and permit rocking when the anti-rocking assemblies 53 are collapsed into the rocking member as will now be described.
Each end 52c, 52d of rocking member 52 defines a hollow recess for respectively receiving a pivotally mounted anti-rocking assembly 53. Anti-rocking assembly 53 is comprised of a hollow rectangular shaped housing 53a having an open side. A pushbutton 53d having a substantially U-shaped cross section is slideably mounted within the opening of housing 53a. A spring (not shown) has one end thereof secured within the hollow interior of push button 53d and the opposite end thereof pressing against the interior surface of housing 53a when pushbutton 53d is mounted therein. Preferably, the spring is normally under compression. Pushbutton 53d has a pair of circular-shaped projections 53e-53f extending outwardly from side 53d-1 and a similar pair of projections 53g-53h extending outwardly from side 53d-2. Projections 53e and 53f are slideably received within a pair of elongated slots 53a-1 and 53a-2 provided in a sidewall of housing 53a and a similar pair of slots 53a-1 and 53a-2 in another sidewall of housing 53a. The projections in pushbutton 53d cooperate with the slots 53a-1 and 53a-2 to limit the range of movement of pushbutton 53d. A pin P or other suitable fastener extends through an opening (not shown) in the rear wall of housing 53a as well as extending through the openings 52e-52f provided in the sidewalls forming the recess 52d to pivotally mount the anti-rocking assembly within the rocking member 52.
The operation of the anti-rocking assembly 53 is as follows:
With the anti-rocking assembly in the erect position shown in FIGS. 3, 6, 7, and 9 the aforementioned coil spring urges push button 53d to extend outwardly and away from the housing 53a and into notch 52g of rocking member 52 to prevent rocking. The free end surfaces S of the anti-rocking assemblies 53 are spaced a distance D (FIGS. 6 and 9) from the underside of support board 51 which is substantially equal to the distance of the center point Cp of arcuate surface 52b from the underside of board 51 so that when the anti-rocking members are in the position shown in FIG. 3 the board 51 is prevented from rocking by making the line L extending between the surfaces S substantially tangential to the center point Cp of arcuate surface 52b. The board 51 is thus prevented from rocking while the rocking member nevertheless provides support at the center point Cp, together with the anti-rocking assemblies, which serve as support legs.
By pressing the button 53d inwardly by a distance sufficient to clear the notch 52g, the anti-rocking assemblies may be pivoted within the recess 52d, as shown in FIG. 9, thereby enabling the support board 51 to be rocked.
If desired, a “half-rocking” condition may be achieved by folding the assemblies 53 on only one side.
The anti-rocking assemblies are moved from the collapsed position to the extended position by applying a downward force (such as finger pressure) in the region R as shown in FIG. 7.
An alternative anti-rocking assembly is shown in FIG. 10 wherein a toggle switch locking device 100, similar to that employed for raising and lowering the casters and shown in detail in co-pending application Ser. No. 10/103,580, may be employed to raise and lower the anti-rocking assemblies.
Rocking members 52 and 54 are each further provided with a pair of mounting members for releasably mounting the bassinet to the support frame. These members are, in one embodiment, identical in design and function. For purposes of simplicity, one such pair of mounting members will be described. Rocking member 52 shown in FIG. 4 is provided with a pair of mounting brackets B1 and B2 integrally joined thereto. The brackets are substantially U-shaped and are each comprised of arms A1 and A2 joined to one another by a center portion C. Arms A1 are integrally joined to the rocking member 52. Making reference to FIG. 5, the inner surfaces of arms A1 and A2 are provided with projections which extend toward one another and are defined by two arcuate concave surfaces S1, S2 which meet at a mid-point P1. Sides A2 have similar concave surfaces S3 and S4 which meet at a mid-point P2.
Brackets B1 and B2, for example, are mounted upon cross-piece 37 by placing the open ends of the U-shaped brackets above cross piece 37 as shown in FIG. 5. As the board 51 is pressed downwardly, arm A2, which is flexible, moves away from arm A1 as the cross rail 37 moves between the points P1 and P2. When the cross piece 37 clears points P1 and P2, arm A2 snaps inwardly, securing the brackets B1 and B2 to the cross rail. Preferably, the brackets of one of the rocker members are inserted onto one of the cross rails and thereafter the second member is mounted in a similar fashion, using the mounted set as a pivot about which the board 51 is swung. The length of the rocking members 52-53 is slightly less than the distance between the inner surfaces of the brackets 31 and 32, enabling the rocker members to fit therebetween.
As an alternative to the mounting brackets described hereinabove, one set of the mounting brackets may be aligned so that their arms extend horizontally and so that the center piece C is integrally joined to the rocker member. The rocker member having these horizontally oriented arms is then mounted first by tilting the support board 52 by an amount sufficient to align the open ends of the brackets having the horizontally aligned arms with the cross rail, such as cross rail 37. When these brackets are snapped into place, the support board may then be swung downwardly using the connected end as a pivot to lock the vertically aligned arms of the remaining rocker member with the remaining cross rail 38.
As a further alternative, a pair of spaced mounting brackets B1′ and B2′ may be pivotally mounted to one of the rocker members. The brackets in the remaining rocker member, which may be similar to the brackets described hereinabove, are integrally joined to the rocker arm and have either horizontally or vertically extending sidewalls. These brackets are mounted first to one of the cross rails and the support board is then swung downwardly using the mounting cross rail of pivot, whereupon the pivotally mounted brackets swing to a vertical position to lock the bassinet to the support frame.
FIGS. 11 through 14 show another alternative embodiment of the present invention wherein the bassinet 50, shown mounted to the frame 20, is provided with a pair of rocking members 60 and 62 which are preferably hollow tubular members formed either of metal or plastic. The intermediate portions of the members 60 and 62 are smoothly arcuate. The ends are bent substantially at a right angle and are pivotally mounted within brackets 61a, 61b and 63a, and 63b. The brackets are provided with a snap-fitting arrangement which locks the rocker members 60 and 62 in the upright or rocking position shown in FIG. 6, as well as the folded down position, shown in FIG. 12.
The underside of board 51 is further provided with two pairs of mounting brackets B1 and B2 having bifurcated arms which extend in a direction substantially parallel to the plane of board 51 and are configured in a manner similar to those shown in FIG. 5 for snap-fittingly locking the bassinet 50 to cross-piece 38.
A bracket 64 is provided with an elongated recess 64a having a curved bottom which conforms to the shape of tubular member 37. A locking member 65 is pivotally mounted to bracket 64 by a suitable pivot pin and is movable between a locking position shown in FIGS. 11 and 12 and an open position which, though not shown, it should be understood that locking arm 65 is rotated either clockwise or counterclockwise through a one-quarter turn so as to be displaced from the elongated groove 64a.
The bassinet 50 is mounted in a manner similar to that described hereinabove, namely the brackets B1 and B2 are aligned with cross-piece 38 and snap-fitted thereto. The bassinet is then swung down to a position where it receives cross rail 37 within groove 64a. The locking arm 65 is then rotated from the open position through a quarter turn to cooperate with recess 64a to embrace tubular member 37.
When the bassinet 50 of FIG. 11 is removed from the support frame 20 and the rocking members, 60, 62 are moved to the upright position shown in FIG. 11, the bassinet may be rocked.
When it is desired to use the bassinet without the rocking feature, the rocker members 60 and 62 are swung to their fold-down positions shown in FIG. 12 whereupon the bassinet is supported by brackets B1 and B2 and locking bracket 64. The length of locking bracket 64 may be increased, if desired, in order to increase the stability of the bassinet when supported by the brackets B1, B2 and 64. Alternatively a pair of legs L1 and L2 may be fixably mounted to the underside of board 51 to further enhance the stability of the bassinet when it is separated from the support frame 20 and is being used with the rocking members folded down.
It should be understood that the infant receiving portion may take any desired form so long it has a bottom or support board, such as a board 51 shown in FIGS. 1 and 11, which will support the weight of the infant and the desired supports.
FIGS. 11 and 12 show one form of bassinet structure which may include a substantially oval shaped frame 70 supported on opposite longitudinal sides of the board 51 by supports S mounted at one end to opposite longitudinal sides of the board and at their opposite ends to the oval-shaped frame 70. A pair of canopy brackets CB are mounted on opposite sides of frame 70 (only one being shown in FIG. 12) to support and swingably mount a pair of gussets G1, G2 which are typically covered with a fabric (not shown) serving as a canopy which may either be set up or folded down. The oval-shaped frame 70 is likewise covered in a suitable fabric (not shown) in a similar fashion, one example being shown in the aforementioned co-pending application Ser. No. 10/103,580.
