BACKGROUND
The present disclosure relates to beds and in particular to beds that can be varied in size. More particularly, the present disclosure relates to a frame that is configured to support a mattress and that can be reconfigured to support mattresses of various sizes.
SUMMARY
The present disclosure relates to a bed including a mattress-support frame. In illustrative embodiments, the mattress-support frame can be reconfigured in the field by a person to change the size and shape of the frame so that a relatively smaller mattress can be supported on the frame to establish a toddler-bed mode of the bed or a relatively larger mattress can be supported on the frame to establish a twin-bed mode of the bed. It is within the scope of the present disclosure to convert the frame to support mattresses of all sizes.
In illustrative embodiments, a convertible bed includes a mattress-support frame comprising components that can be moved relative to one another by a person in the field to change the width and/or the length of the frame. The convertible bed also includes a releasable lock system for locking movable pieces included each of those components relative to one another to establish, for example, a toddler-bed mode in which the frame has a relatively narrow width and short length that is sized to support a toddler-bed mattress, or, at the option of the user, to establish, for example, a twin-bed mode in which the frame has a relatively wider width and longer length that is sized to support a twin-bed mattress.
In illustrative embodiments, the convertible bed includes a variable-width headboard, a variable-width footboard, and variable-length side walls arranged to lie in laterally spaced-apart relation to one another and to interconnect the headboard and footboard. The convertible bed also includes a variable-width mid-section arranged to interconnect the side walls. In illustrative embodiments, the headboard, footboard, side walls, and mid-section are part of a convertible bed kit that also comprises a set of relatively short toddler-bed slats for underlying and supporting a toddler-bed mattress when a toddler-bed mode of the bed is established and a set of relatively longer twin-bed slats for underlying and supporting a relatively larger twin-bed mattress when a twin-bed mode of the bed is established.
In illustrative embodiments, each of the variable-width headboard, footboard, and mid-section comprise first and second movable segments that can be moved relative to one another when unlocked to vary the width of the headboard, footboard or mid-section. The headboard comprises interlocking E-shaped and Pi-shaped movable headboard segments while the footboard comprises interlocking C-shaped and T-shaped movable footboard segments.
In illustrative embodiments, the convertible bed kit in accordance with the present disclosure also includes a headboard segment-motion lock comprising top and bottom toddler-bed headboard caps and relatively longer top and bottom twin-bed caps. In the toddler-bed mode, the relatively short toddler-bed headboard caps are selected from the kit and mounted by the caregiver on the drawn-together first and second movable headboard segments to lock those segments to one another to establish a narrow-width headboard. Alternatively, in the twin-bed mode, the relatively longer twin-bed headboard caps are selected from the kit and mounted by the caregiver on the spread-apart first and second movable headboard segments to lock those segments to one another to establish a wide-width headboard. Similarly, the convertible bed kit also includes short top and bottom toddler-bed footboard caps and relatively longer top and bottom twin-bed footboard caps for use in locking the movable footboard segments of the footboard together when drawn together to establish a narrow-width footboard or when spread apart to establish a wide-width footboard.
