1. Field of the Invention
The present invention relates to furniture and more particularly pertains to a cabinet that can house a folding mattress and allows the mattress to be deployed as a bed.
2. Background of the Prior Art
The broad concept of a cabinet bed is not new. Nevertheless, prior cabinet beds tended to suffer from one or more of several disabilities that limited their usefulness; for example, bulky and un-prepossessing appearance, complicated mechanism and inconvenient operation to deploy into a bed rendering it difficult to fold and unfold the bed and compounding its costs, unstable sleeping platform upon deployment, lack of storage drawers, significant lack of comfort, and other problems.
These disabilities are obvious to the extent that, though the demand for space-saving beds is high, there is a dearth of cabinet beds available today.
U.S. Pat. No. 3,638,249 to Katsigarakis, as well as several other U.S. and foreign patents, suffer from the similar disability of having the front and back panels of the cabinet hinged to a central base from which deployment of the sleeping platform is accomplished, with or without mechanical mechanisms, by folding the front and back panels into a horizontal position to create a mattress platform. This basic method of deployment is such that there can be no functioning storage drawers and that any objects placed on top of the cabinet when in the closed position must be removed prior to deployment into a bed.
U.S. Pat. No. 186,632 to Smith; U.S. Pat. No. 189,303 to Crosby; and U.S. Pat. No. 239,805 to Knapp all describe a cabinet bed in which the front of the cabinet folds out into a horizontal position to create a sleeping platform supported by a ‘foot’ at the end of the front panel. The ‘foot’ is hinged to the front panel and is folded downward and held in place to support the mattress platform at the same height as the base of the cabinet. These suffer from the similar disability of deploying the bed, such that the mattress deploys with the front panel thereby creating additional weight in addition to which, once in the horizontal position, the person deploying the bed must support the weight of both the panel and mattress while ensuring that the ‘feet’ are securely in place.
U.S. Pat. No. 1,170,149 to Gustafson is a cabinet bed that deploys using a two-piece platform that nests into each other. The cabinet mattress platform is supported by a pair of hinged legs that rotate downward to provide support where the two-pieces of the platform nest. Another piece on a hinge and spring rotates out and down to support the foot of the bed. The Gustafson cabinet suffers from a number of disabilities including: a complicated mechanism requiring stop pins and angle irons to prevent the foot from going beyond the vertical position; lack of storage drawers; lack of continuous support of the mattress platform, a mattress platform that deploys close to the floor; and an overall design that requires any number of independent actions to safely deploy the platform and mattress, making it unwieldy and difficult to deploy.
While each of the above mentioned devices may be effective to some degree in providing a folding cabinet bed, none of the references disclose a simple cabinet with few moving parts that can open to reveal a platform bed of any height supporting a variety of mattresses in a variety of sizes and containing storage drawers accessible in an open or closed position.
The present invention provides a solution to the above and other problems by enabling a simply designed folding cabinet bed with a telescoping drawer/bed frame assembly in an attractive piece of furniture that opens into a full-length platform bed of any height off the floor that can be configured to fit a mattress of any size.
It is, therefore, an object of the present invention to enable a folding cabinet bed that avoids the disadvantages of the prior art.
It is another object of the present invention to enable a folding cabinet bed that presents a decorative appearance in the closed configuration. A further related object of the present invention is to enable a folding cabinet bed having a simple design.
It is another object of the present invention to enable a folding cabinet bed with a telescoping frame to support the sleeping platform that closes into a compact configuration within the cabinet and extends to the desired length of the sleeping platform. A related object is to enable a folding cabinet bed having a telescoping drawer/bed frame assembly that is compact and easy to construct. A further related object is to enable a folding cabinet bed having a telescoping drawer/bed frame assembly in which the telescoping rail mechanism can be constructed using readily available hardware such as drawer slides or similar mechanisms, or can be constructed using dadoes with mating runners in and on the rails themselves with a pin-in-dado or other mechanism to ensure that the rails extend to the proper length to accomplish the telescoping and accommodate the mattress platform.
It is another object of the present invention to enable a folding cabinet bed with a telescoping frame in which the telescoping frame can be easily configured to adapt to any desired height for the sleeping platform. A related object of the present invention is to enable a folding cabinet bed with a telescoping frame in which the telescoping rails provide continuous support for the sleeping platform and are configured to support the sleeping platform on both sides and in the middle. A further related object is to enable a folding cabinet bed having a telescoping drawer/bed frame assembly in which the telescoping frame houses drawers that nest into the frame when in the closed position, and that are easily accessible whether the cabinet is closed or in a fully opened position.
It is another object of the present invention to enable a folding cabinet bed that can be securely latched when closed to withstand the outward pressure of the folded mattress. It is a related object of the present invention to enable a folding cabinet bed that has an internal latching mechanism to prevent accidental deployment of the mattress platform.
It is another object of the present invention to enable a folding cabinet bed wherein the interior of the cabinet is configured with an interior stretcher between side panels that can hold the mattress inside the cabinet while the frame and platform are being deployed thus removing the additional weight of the mattress during bed deployment.
It is another object of the present invention to enable a folding cabinet bed having a damper, spring, or other such device that can be easily installed to assist in the deployment of the front panel.
It is yet another object of the present invention to enable a folding, telescoping frame cabinet bed that may be easily and efficiently manufactured and marketed. A related object of the present invention is to enable a folding, telescoping frame cabinet bed that is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such a folding cabinet bed economically available to the buying public.
It is another object of the present invention to enable a folding, telescoping frame cabinet bed comprising an attractive cabinet enclosure and a mattress.
In accordance with the above and other objects, a folding, telescoping frame cabinet bed is described for providing a piece of furniture that opens to a full-length bed in an attractive chest with a small footprint. The invention comprises a cabinet that houses a mattress and allows the mattress to be deployed as a bed. The cabinet is deep and tall enough to enclose a folded mattress and of sufficient width to accommodate standard sizes of mattresses, without a separate mattress platform. Hinges on the bottom of the front wall of the cabinet enable the cabinet to be opened vertically so that the front wall folds down to a sleeping position. A separate extension panel, connected to the front wall, further deploys to create a sleeping platform of desired length to accommodate the mattress. Dampers, springs, or other mechanical devices can be installed to assist in lowering or raising the front cabinet wall. When folded down, the front cabinet wall and extension panel rest on a frame consisting of a plurality of nesting rails attached to the sidewalls and center support of the cabinet that telescope outward. Drawers are provided that nest within the telescoping rails. The rails and drawers are supported by casters to enable the drawers and rails to be extended away from the cabinet to create a level frame to support the sleeping platform. In a closed position, the drawers and rails slide into the cabinet base. The drawers may also include storage space for pillows, bedding, and the like. Latching means holds the cabinet securely closed to withstand the outward pressure of the folded mattress. A safety chain may be provided to prevent the front cabinet wall from falling if accidentally opened.
When closed, the cabinet conceals and protects a mattress and bedding in an attractive false-fronted chest with practical tabletop surface and well-appointed hardware. When opened, the cabinet provides twin, full, queen, or king-size sleeping comfort, complete with headboard. The cabinet front, extension panel, and rails become the sleeping platform. The rails rest on casters on the floor and support the platform off the floor thereby providing further comfort. After use, simply fold the extension panel and front wall into the cabinet, lock the side catches, and push the drawers and rails into the cabinet base.
The various features of novelty that characterize the invention will be pointed out with particularity in the claims of this application.
The above and other features, aspects, and advantages of the present invention are considered in more detail, in relation to the following description of embodiments thereof shown in the accompanying drawings, in which:
a and b illustrates a front and side elevational view of a folding cabinet bed in the closed configuration according to a second embodiment of the present invention.
The invention summarized above and defined by the enumerated claims may be better understood by referring to the following description, which should be read in conjunction with the accompanying drawings in which like reference numbers are used for like parts. This description of an embodiment, set out below to enable one to build and use an implementation of the invention, is not intended to limit the enumerated claims, but to serve as a particular example thereof. Those skilled in the art should appreciate that they may readily use the conception and specific embodiments disclosed as a basis for modifying or designing other methods and systems for carrying out the same purposes of the present invention. Those skilled in the art should also realize that such equivalent assemblies do not depart from the spirit and scope of the invention in its broadest form.
Referring to the drawings,
An extension panel 35 is pivotably attached to the free end of the front wall 15 by hinge 38, as shown in
The cabinet 10 is mounted on a hollow base 37. A drawer 40 is provided in the base 37 below front wall 15 and under the bottom panel 25. At least one handle 43 is provided on the face 46 of drawer 40. The face 46 of drawer 40 extends the entire width of cabinet 10. A platform support structure 48 comprising a plurality of extendable telescoping rails 50 is provided within the base 37 between the sidewalls of the drawer 40 and the cabinet sidewalls 21, 22. The extendable rails 50 can be pulled out of the base 37 in a telescoping fashion approximately perpendicular to the base 37 to hold a bed platform 51, comprising the front wall 15 and extension panel 35, above the floor. In a preferred embodiment, at least three sets of telescoping rails 50 are provided to support the outside portions and center of the bed platform 51. A center support 52 may be provided under the bottom panel 25 between the sidewalls 21, 22.
Support structure 48 further comprises appropriate support mechanisms, such as casters 53, that elevate and carry the telescoping rails 50, and allow them to move easily in and out of the cabinet 10 by opening or closing the drawer 40. In an open configuration, the casters 53 provide support such that front wall 15, extension panel 35, and bottom panel 25 form a common plane above the floor or surface upon which the cabinet 10 is placed. When fully extended, the drawer 40, rails 50, and casters 53 hold up the front wall 15 and extension panel 35.
A pair of latching mechanisms 55 on each of sidewalls 21, 22 maintains the front wall 15 in the closed configuration. Drawer 40 may also be provided with a latching mechanism (not shown) to hold the drawer 40 in the open or closed position. Additionally, a safety chain 58 or strap may be provided to prevent the front wall 15 from falling if accidentally opened.
In a preferred embodiment, the cabinet 10 of the present invention is sized and configured to enable a mattress to be enclosed within such cabinet 10. Cabinet 10 can be configured to hold a single-size, full-size, queen-size, or king-size mattress and may optionally include space for one or more pillows and bedclothes. Such pillows and bedclothes may be stored in compartments 61, 62 in the drawer 40. The stretcher 27 holds the mattress inside the cabinet 10 while the support structure 48 and platform 51 are being deployed thus removing the additional weight of the mattress during bed deployment. Front wall 15 may be decorated to present an attractive appearance for a false cabinet or to mimic a piece of furniture, such as a chest of drawers, credenza, bureau, dresser, and the like.
In use, cabinet 10 can be opened vertically from top to bottom. First, the drawer 40 is pulled out to the full extent enabled by the rails 50. Next, the latching mechanisms 55 are released. If provided, the safety chain 58 is unhooked. Then, front wall 15 folds down and extension panel 35 is folded out to complete the length of the bed. The mattress is exposed and can be opened to a sleeping position. In an open configuration, back wall 18 becomes the headboard of the bed, with top panel 12 overhanging. In such an embodiment, the cabinet 10 need not be moved away from a wall to open the cabinet 10 and extend the bed platform 51 to a full-sized bed. The support structure 48 enables the sleeping platform 51 to be in a raised position above the floor on which the cabinet 10 is placed.
In an alternate embodiment, extension panel 35 need not be pivotably attached to the front wall 15 and, instead, may be slidably connected to the inner surface of the front wall 15, by appropriate slides. When the front wall 15 is folded down to the sleeping platform 51, the extension panel 35 is slid out, parallel to front wall 15. At the end of its travel, extension panel 35 drops down to form a common plane with the front wall 15 on the sleeping platform 51.
a and b show cabinet 10 in an alternate configuration. The enclosure formed by the top panel 12, sidewalls 21, 22, and bottom panel 25 is closed by a pair of doors 65, 66 pivotably attached along a side edge of the doors 65, 66 to a forward edge of sidewalls 21, 22, respectively. A stretcher 27 may be provided between sidewalls 21, 22 at the top of the cabinet 10. Doors 65, 66 may include opening hardware, such as handles 69, 70. The front wall 15 is enclosed by the doors 65, 66. To create a sleeping platform, the front wall 15 is pivotably attached to the front edge of bottom panel 25 by hinge 30 at the bottom of the front wall 15. In a preferred embodiment, a damper, spring, or other such device can be installed to assist in the deployment of the front wall 15. In this configuration, the front wall 15 is sized and configured to fit between sidewalls 21, 22 so that the front wall 15 can fit inside the cabinet 10 in the closed configuration. A safety chain or latch may be provided to prevent the front wall 15 from falling when the doors 65, 66 are opened. Doors 65, 66 may be provided with a latching mechanism (not shown) to hold the doors 65, 66 in the open or closed position.
As in the previous configuration, the extension panel 35 is pivotably attached to the free end of the front wall 15 by hinge 38, as shown in
As described above, extension panel 35 need not be pivotably attached to the front wall 15 and, instead, may be slidably connected to the inner surface of the front wall 15, by appropriate slides. When the front wall 15 is folded down onto the platform support structure 48, the extension panel 35 is slid out, parallel to front wall 15. At the end of its travel, extension panel 35 drops down to form a common plane with the front wall 15.
To deploy the bed, the doors 65, 66 on cabinet 10 can be opened. First, the drawer 40 is pulled out to the full extent enabled by the rails 50 to deploy the platform support structure. Next, the latch or safety chain, if provided, is released. Then, front wall 15 folds down and extension panel 35 is folded out to complete the length of the bed and expose a mattress. The mattress can then be opened to a sleeping position.
