DESCRIPTION OF THE EMBODIMENTS

(18) In the following description, like reference characters designate like or corresponding parts throughout the several views. Also in the following description, it is to be understood that such terms as forward, rearward, left, right, upwardly, downwardly, and the like are words of convenience and are not to be construed as limiting terms.

(19) Referring now to the drawings in general and FIG. 1 in particular, it will be understood that the illustrations are for the purpose of describing a preferred embodiment of the inventions and are not intended to limit the inventions thereto. As best seen in FIG. 1A, a bed, generally designated 10, is shown constructed according to the present inventions. The bed 10 is convertible between a sofa configuration and one or more bed configurations.

(20) FIG. 1A depicts bed 10 in a sofa configuration. In the sofa configuration shown, bed 10 includes a stationary bed support assembly 12 having a stationary bed frame 14, a back rest 16 and a pair of side arms 20a and 20b. Back rest 16 may be attached to a portion of stationary bed support assembly 12 to support a user's back while bed 10 is in the sofa configuration. For example, as seen in FIG. 3, back rest 16 may be attached to a back rail 66 of stationary bed support assembly 12.

(21) Side arms 16a and 16b attached to frame 14 and can be used to support a user's arm while bed 10 is in sofa configuration. While in a bed configuration, side arms 20a and 20b may also function as a head board and footboard, or vice versa. As seen in FIG. 1A, stationary bed support assembly 12 includes a pair of legs 22a and 22b attached to the front portion of frame 12 for elevation and support. A second pair of legs 24 may also be attached to the back of frame 12. In other embodiments, frame 12 may only include a first pair of legs 22 wherein the back portion of frame 12 is mounted onto a surface such as a wall.

(22) Stationary bed support assembly 12 may support one or more cushions to provide a surface for a user to sit and lay on. For example, the cushion may comprise a mattress 30 positioned on top of stationary bed support assembly 12. In one embodiment, mattress 30 may comprise a pair of two stacked mattresses. Stationary bed support assembly 12 may support mattresses of various sizes. For instance, mattress 30 may be a twin size mattress.

(23) A storage compartment 40 may also be included with bed 10. Storage compartment 40 may comprise one or more drawers underneath stationary bed support assembly 12. Storage compartment 40 may also include handles 42 on a front face to help pull the storage compartment 40 from underneath of stationary bed support assembly 12.

(24) Turning to FIG. 1B, an embodiment of bed 10 is shown wherein storage compartment 40 forms a trundle 44. As seen in FIG. 2A, storage compartment 40 may further include one or more pairs of wheels 46 adapted to facilitate pulling trundle 44 from underneath stationary bed support assembly 12. Wheels 46 may also be included in other embodiments of storage compartment 40; for example, to facilitate pushing or pulling of drawers. As best seen in FIGS. 2C and 5B, storage compartment 40 includes a front 50, a pair of sides 52 and a bottom 54 that forms a recess for receiving mattress 32. A back piece 56 may also be included to help secure mattress 32 within the recess.

(25) FIG. 1C depicts an embodiment of bed 10 shown in a bed configuration. In the bed configuration shown, bed 10 is extended out from its sofa configuration to a king size bed with mattress 32. In some embodiments, mattress 32 may be a non-stored mattress (for example, a pair of stacked mattresses). In other embodiments, mattress 32 may be stored in the storage compartment 40. Mattress 32 may be stored as is within storage compartment 40, or may form a trundle with storage compartment 40 (as seen in FIG. 1B). Mattresses 30 and 32 may vary in size. For example, mattresses 30 and 32 may each comprise a twin size mattress that form a king size bed when placed adjacently with each other.

(26) FIG. 2D provides a view of one embodiment of bed 10 transitioning from a sofa configuration to a bed configuration. Stationary bed support assembly 12 includes a plurality of slats 62 supported at one end by a front rail 64 and at an opposing end by a back rail 66. The plurality of slats 62 are adapted to support mattress 30. Movable bed support assembly 70 includes a plurality of slats 72 supported at one end by a front rail 74 and at an opposing end by a back rail 76. The plurality of slats 72 of movable bed support assembly 70 are positioned parallel with the plurality of slats 62 of stationary bed support assembly 12, and interlock with one another.

(27) Slats 72 of movable bed support assembly 70 overlap with front rail 64 to provide additional structural support for slats 72. In the sofa configuration shown in FIGS. 2B and 5A, slats 62 and 72 both provide support for mattress 30. Conversely, as shown in FIGS. 2C and 5C wherein bed 10 is in a bed configuration with the movable bed support assembly 70 extended, slats 62 are adapted to support mattress 30 and slats 72 are adapted to support mattress 32. In the embodiment shown, slats 62 and slats 72 are substantially the same length. Other embodiments may have slats of varying length to accommodate different mattress sizes.

(28) Movable bed support assembly 70 includes a pair of front legs 78 at its front rail 74 for elevation and support of mattress 32. In some embodiments, movable bed support assembly 70 may also include a pair of rear legs 79 attached to the back portion of its frame for additional elevation and support.

(29) As shown in FIGS. 2B and 2C, the back rail 76 of movable bed support assembly 70 abuts the back rail 66 of stationary bed support assembly 12 while bed 10 in a sofa configuration. Similarly, front rail 74 of movable bed support assembly 70 abuts the front rail of stationary bed support assembly 12. The railings of stationary bed support assembly 12 may serve as a stop to prevent movable bed support assembly 12 from sliding past the backrest 16.

(30) Returning to FIG. 2D, as bed 10 transitions from a sofa configuration to a bed configuration, the back rail 76 moves away from back rail 66 and toward front rail 64 as movable bed support assembly 70 extends away. In the embodiment shown, front rail 64 acts as a stop to prevent movable bed support assembly 70 from completely extending away from stationary bed support assembly 12, wherein front rail 64 abuts back rail 76 of movable bed support assembly 70. In other embodiments, an additional rail may be added to the stationary bed support assembly 12 to prevent movable bed support assembly 70 from extending past a certain distance. For example, an additional railing adapted as a stop may serve as a preset for the correct sizing to accommodate a second mattress 32.

(31) FIG. 6 shows an enlarged view of front rail 64. In the embodiment shown, front rail 64 is scalloped along its top edge. Scallops 80 are positioned directly below slats 72, and facilitates their movement across front rail 64. Addition of scallops 80 enables the movable bed support assembly 70 to smoothly slide forward and backward as bed 10 switches between configurations.

(32) In operation, bed 10 provides the opportunity of having multiple configurations. In one configuration, bed 10 is in a sofa configuration that may be used for either sitting or lying down. As seen in FIGS. 1A and 4A, the movable bed support assembly 70 and storage compartment 40 remain with stationary bed support assembly 12.

(33) In another configuration, as seen in FIGS. 1B and 4B, the storage compartment 40 is adapted for use as a trundle bed that may be extended out while bed 10 is in a sofa configuration.

(34) In still another configuration, as seen in FIGS. 1C and 4C, the movable bed support assembly may be extended out as a king size bed when the mattress stored in storage compartment 40 is placed on top of it. Storage compartment 40 may be extended out with movable bed support assembly in this configuration. Alternatively, movable bed support assembly 70 may be extended out to form a king size bed using a non-stored mattress (e.g. removing a top mattress from a pair of stacked mattresses on stationary bed support assembly 12 when the storage compartment 40 is used for other items, like toys).

(35) The storage compartment and movable bed support assembly may be used for other convertible furniture assemblies. For example, FIG. 7 depicts a bed 10 in a bunk bed configuration, wherein the bed 10 includes a stationary bed support assembly 12, a movable bed support assembly 70, and a storage compartment 40. The stationary bed support assembly 12 includes a stationary bed frame 14, a back rest 16 and a pair of side arms 20a and 20b. The side anus 20a and 20b extend up and further include a bunk bed support assembly 18 to support a second mattress. Back rest 16a may be attached to a portion of stationary bed support assembly 12 to secure a first mattress, and back rest 16b may be attached to the bunk bed support assembly 18 to secure a second mattress.

(36) FIG. 8 provides another example with a sofa 10 having a stationary bed support assembly 12, a movable bed support assembly 70, and a storage compartment 40. The stationary bed support assembly 12 includes a stationary bed frame 14, a back rest 16 and a pair of side arms 20a and 20b. Back rest 16 is attached to a portion of stationary bed support assembly 12 to support a user's back.

(37) Certain modifications and improvements will occur to those skilled in the art upon a reading of the foregoing description. By way of example, movable bed support assembly may comprise two separate frames having its own sets of interlocking slats supported by front and back rails. Multiple frames for movable bed support assembly may be useful for providing additional presets to accommodate a third mattress or second mattresses of various sizes. It should be understood that all such modifications and improvements have been deleted herein for the sake of conciseness and readability but are properly within the scope of the following claims.
