       STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH  
         [0002]    Not Applicable.  
         FIELD OF THE INVENTION  
         [0003]    The invention relates generally to infant equipment and, more particularly, to infant beds for coupling to an adult bed.  
         BACKGROUND OF THE INVENTION  
         [0004]    It is well known that there are advantages to having a newborn sleep in proximity to its mother. For example, when the infant is close by, a mother can easily nurse the infant as well as take care of other needs. Close proximity is also a significant benefit for mothers who have undergone a Cesarean section. In addition, research has shown that newborns rely on proximity to their mothers to regulate body heat, breathing, and cardiac rhythms.  
           [0005]    While there have been attempts to provide proximity and convenience to a mother and her infant, known devices, such as bassinets, do not provide the level of closeness that is desirable for many new mothers. Further, conventional devices that attach to a bed can be cumbersome and render it difficult for a mother to get on and off the bed.  
           [0006]    It would therefore, be desirable to provide an infant bed that is slidably engageable to a bed frame for allowing an adult to be close to an infant to easily get on and off the adult bed.  
         SUMMARY OF THE INVENTION  
         [0007]    The present invention provides an infant bed that is positionable alongside an adult bed to which the infant bed is secured. Although the invention is primarily shown and described with reference to a hospital-type bed, it is understood that the infant bed can be coupled to a variety of beds having a frame that can support the infant bed alongside thereof.  
           [0008]    In one aspect of the invention, an infant bed has a top portion and a bottom portion, which can be secured to an adult bed frame. Barriers upwardly extend from the top portion to form an interior region for confining an infant. A coupling mechanism, such as mounting rods extending from the bottom portion of the infant bed, secures the infant bed to the adult bed. In one embodiment, the mounting rods are received by corresponding structural members rigidly extending from the frame of the adult bed. The infant bed further includes a slidable bracket mechanism coupled to the bottom portion of the infant bed for allowing the infant bed to be moved along a length of the adult bed.  
           [0009]    In a further aspect of the invention, a method for maintaining proximity between an infant and an adult includes placing a baby into an infant bed that is movable alongside a length of an adult bed. The infant bed is movable between first and second positions that provide closeness to the infant and facilitate egress from the adult/infant bed assembly. In one embodiment, a coupling mechanism secures a bottom portion of the infant bed to the adult bed and a slidable bracket mechanism enables longitudinal movement of the infant bed with respect to the adult bed.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0018]    [0018]FIG. 1 shows an exemplary embodiment of an infant bed  100  in accordance with the present invention. The infant bed can be secured to an adult bed and adjusted to a desired position along the length of a bed as indicated by arrow  101 . Thus, an adult can move the infant bed  100  to facilitate getting on and off the bed, while maintaining a desired level of proximity with a newborn in the infant bed.  
         [0019]    The infant bed  100  includes a flat bottom  102  from which four barriers  104  upwardly extend to confine an infant within the interior. It is understood that the barriers can comprise a variety of configurations that are suitable to keep an infant within the infant bed. Exemplary barriers include solid walls, railed fences and slotted barricades. It is further understood that the infant bed interior can have different geometric configurations including square, rectangular, circular, ovular and polygonal.  
         [0020]    As shown in FIG. 2, the infant bed  100  is engageable to a bed frame  10 , such as the frame of a hospital bed. The infant bed  100  is well-suited for use with a wide variety of bed frames generally having frame members for supporting a mattress and/or boxspring. The bed frame  10  can include a first pair of opposed frame members  12 , 14  for supporting a mattress along its length and a second pair of opposed frame members  16 ,(not shown) located at the head and foot of the bed frame for supporting the mattress along its width. The bed frame can further include a flat support member  20  that provides a flat surface adapted to support the underside of the mattress.  
         [0021]    [0021]FIG. 3 shows an exemplary mechanism for coupling the infant bed to the hosptial bed frame. The coupling mechanism includes first and second mounting rods  106 , 108  rigidly extending from a base of the infant bed. In one embodiment, the rods  106 , 108  are fixedly coupled to a bottom portion of the infant bed base, as described below, to allow the infant bed to move along a length of the mother&#39;s bed. The rods  106 , 108  are insertable within corresponding first and second structural members  110 , 112  that are securable to the bed frame. The rods can be secured to the structural members using suitable permanent and removable devices including, nuts, bolts, rivets, interference fits, adhesives, welds, lock nuts and pins. In an illustrative embodiment, removable locking pins are used to secure the rods to the structural members. The pins prevent the infant bed from unintentional disengagement from the bed frame while allowing a user to remove the infant bed when desired.  
         [0022]    The structural members  110 , 112  can be affixed to the bed frame using nut, bolt and washer assemblies to secure the members to the frame. In one embodiment, cross members  113  affixed to ends of the structural members are bolted to the bed frame, such as to the support member  20 , in at least one location  115 .  
         [0023]    The position of the infant bed  100  can be adjusted along the length of the hospital bed as shown by the bi-directional arrow  101  shown in FIG. 1. In one embodiment, the infant bed is slidable with respect to the rods  106 , 108 , which are secured to a bottom portion of the infant bed base. A variety of suitable mechanisms can be used to allow the infant bed  100  to slide along the length of the bed. Exemplary mechanisms include brackets, rods, and channels.  
         [0024]    [0024]FIG. 4 (bottom view) shows an exemplary arrangement for allowing the infant bed to slide to a desired location alongside the adult sized bed. The base  102  of the infant bed includes a top portion  150  that is movable with respect to a bottom portion  152  to which the rods  106 , 108  are secured. The base further includes sliding bracket mechanisms  154   a,b  that allow the base top portion  150  to move while the base bottom portion  152  remains in a fixed position relative to the bed frame.  
         [0025]    In one embodiment, opposed first and second base extension members  156   a,b  rigidly extend from bottom edges of the flat bottom of the infant bed. A first inner base member  158   a  is secured to the bottom portion  152  of the base in spaced opposition to the first base extension member  156   a , such the outer and inner base members form a channel. The bottom portion of the base, which is fixed relative to the bed frame, includes opposed structural members  160   a,b  to which the outwardly extending mounting rods  106 , 108  are secured. In one embodiment, the first inner base member  158   a  is connected to the structural members of the base bottom portion. Similarly, the second inner base member  158   b , which is affixed to the structural members  160 , is disposed in spaced opposition to the second base extension member  156   b  so as to form a channel. The bottom portion of the base can further include cross members  162   a,b  for increasing the overall structural integrity of the device.  
         [0026]    The first bracket mechanism  154   a  is adapted for operating in the first channel formed by the first base extension member and the first inner base member. The second bracket mechanism  154   b  is adapted for operating in the second channel formed by second base extension member and the second inner base member. Each bracket mechanism includes first and second track-rail/slider assemblies for coupling to the base extension members. An exemplary track-rail sliding bracket mechanism is identified as Part No. S28T-120/540, which is shown in FIG. 5, available from Rollon Corporation of New Jersey and web site www.rollon.com.  
         [0027]    The track-rail of the first bracket mechanism  154   a  is secured to an inner surface of the first base extension member (top portion of base)  156   a  and the corresponding slider is secured to a corresponding surface of the inner base member (bottom portion of base)  158   a . Similarly, the track-rail and slider of the second bracket mechanism  154   b  are coupled to the respective second base extension member  156   b  and the second inner base member  158   b . The sliders are easily displaceable within the track by means of a ball bearing cage. The slidable bracket mechanisms are disposed within the first and second channels to allow the top portion of the base to slide with respect to the bottom portion of the base. This arrangement allows the infant bed to be slidably positioned alongside the bedframe.  
         [0028]    FIGS.  6 - 7  show an alternative embodiment of an infant bed  200  that is movable alongside an adult bed (not shown) in accordance with the present invention. The infant bed includes a top portion  202  having a area for containing an infant and a bottom portion  204 . In one embodiment, the bottom portion  204  of the infant bed includes opposed first and second members  204   a,b  secured to the top portion  202 .  
         [0029]    The first and second members  204  of the infant bed bottom portion are secured to respective first and second slidable bracket mechanisms  206   a,b , which are also secured to a coupling mechanism, shown as a pair of rigid mounting rods  208   a,b . The mounting rods  208  can be secured to structural members (not shown) extending from the adult bed. The opposed first and second slidable bracket mechanisms  204   a,b  enable the infant bed to move alongside the adult bed.  
         [0030]    In another feature of the invention, the base includes a locking mechanism for securing the infant bed in position along its length of travel. The locking mechanism allows a user to affix the infant bed in a position after it has been moved to a desired position alongside the bed. Exemplary locking mechanisms include pins, bolts, interlocking surface features, and interference devices.  
         [0031]    It is understood that various modifications and substitutions can be made to the embodiments described herein without departing from the present invention. For example, the type and number of devices corresponding to the slidable bracket mechanisms can be readily modified by one of ordinary skill in the art. In addition, a wide variety of devices known to one of ordinary skill in the art can be used for the coupling mechanism securing the infant bed to a bed frame. It is understood that further changes from the particular embodiments shown and described herein will be readily apparent.
