There are many advantages to lofting a bed in circumstances where floor space is scarce, such as in a dormitory situation. It is advantageous to use the same floor space for the bed and for other furniture such as a desk, couch or dresser. It is not possible, however, to loft every bed without making permanent modifications that can blemish the bedframe. Also, not every bed frame is of the exact same dimensions. Therefore, there is a need for a system for lofting a bed that can accept a broad range of existing bed styles and designs without making modifications to the bedframe.
The present invention is a bed loft comprising a pair of end assemblies and at least one support beam. Each end assembly comprises a first post and a second post. The first post comprises at least one support beam prong for insertion into the support beam, at least one end assembly prong for insertion into an end assembly support beam, and a receiver for holding a foot of a bedpost. The second post comprises at least one end assembly support beam for receiving an end assembly support prong and a receiver for holding a foot of a bedpost. The length and width of the bed loft is adjusted by sliding the support beam and end assembly support beam along the support prongs and end assembly prongs, respectively. Locking means fix the position of the support beam and end assembly support beam. In another embodiment of the present invention the first and second posts are further broken down into smaller sections. The height of the loft can be adjusted by adding or subtracting sections. The present invention also discloses a method for assembling an adjustable bed loft.

The third post 14BL is comprised of a third support beam prong 22C, a fourth support beam prong 22D, a fourth end assembly prong 17D, a fifth end assembly prong 17E, a sixth end assembly prong 17F, and a third receiver unit 20C. The support beam prongs 22C, 22D have one end that is rigidly attached to the third post 14BL and one end that is adapted for insertion into one of the support beams 18U, 18L. The support beam prongs 22C, 22D are attached to the front side of the third post 14BL so that they face the back side of the first post 14FL. The end assembly prongs 17D, 17E, 17F have one end that is rigidly attached to the third post 14BL and one end that is adapted for insertion into one of the end assembly support beams 16D, 16E, 16F. The end assembly prongs 17D, 17E, 17F are attached to the right side of the third post 14BL so that they face the left side of the fourth post 14BR.
The fourth post 14BR is comprised of a fourth end assembly support beam 16D, a fifth end assembly support beam 16E, a sixth end assembly support beam 16F and a fourth receiver unit 20D. The end assembly support beams 16D, 16E, 16F have one end that is rigidly attached to the fourth post 14BR and one end that is adapted for receiving one of the end assembly prongs 17D, 17E, 17F. The end assembly support beams 16D, 16E, 16F are attached to the left side of the fourth post 14BR so that they face the right side of the third post 14BL.
Each end of the support beam 18U is adapted for receiving support beam prongs 22A, 22C. Each end of the support beam 18L is adapted for receiving support beam prongs 22B, 22D.
The end assembly prongs 17A, 17B, 17C of the first post 14FL are inserted into the end assembly support beams 16A, 16B, 16C of the second post 14FR. The distance that the end assembly prongs 17A, 17B, 17C are inserted into the end assembly support beams 16A, 16B, 16C is set to match the width of the head board or footboard 6 of the bed frame 2 such that the legs 4A, 4B of the bed frame 2 will rest inside the receiver units 20A, 20B. The locking means 26 is then used to fix the position of the end assembly support beams 16A, 16B, 16C. Thus, when fully assembled the first post 14FL and second post 14FR are rigidly connected to each other at a distance that fits the width of a desired bed frame 2.
The end assembly prongs 17D, 17E, 17F of the third post 14BL are inserted into the end assembly support beams 16D, 16E, 16F of the fourth post 14BR. The distance that the end assembly prongs 17D, 17E, 17F are inserted into the end assembly support beams 16D, 16E, 16F is set to match the width of the head board or footboard 6 of the bed frame 2 such that the legs 4C, 4D of the bed frame 2 will rest inside the receiver units 20C, 20D. The locking means 26 is then used to fix the position of the end assembly support beams 16D, 16E, 16F. Thus, when fully assembled the third post 14BL and fourth post 14BR are rigidly connected to each other at a distance that fits the width of a desired bed frame 2.
The support beam prongs 22A, 22B of the first post 14FL are inserted into a first end of the support beams 18U, 18L. The support beam prongs 22C, 22D of the third post 14BL are inserted into a second end of the support beams 18U, 18L. The distance that the support beam prongs 22A, 22B, 22C, 22D are inserted into the support beams 18U, 18L is set to match the length of the bed frame 2 such that the legs 4A, 4B, 4C, 4D of the bed frame 2 will rest inside the receiver units 20A, 20B, 20C, 20D. The locking means 26 is then used to fix the position of the support beams 18U, 18L. Thus, when fully assembled the end assemblies 12F, 12B are rigidly connected to each other by the support beams 18U, 18L at a distance that fits the length of a desired bed frame 2.
In another embodiment of the invention, the support beams 18U, 18L and end assembly support beams 16A, 16B, 16C, 16D, 16E, 16F can themselves be of a telescoping construction wherein the support beam 18U, 18L or end assembly support beam 16A, 16B, 16C, 16D, 16E, 16F collapses inside itself. This helps with storage and assembly of the universally adjustable bed loft 10. The support beam prongs 22A, 22B, 22C, 22D and end assembly prongs 17A, 17B, 17C, 17D, 17E, 17F may also be of a telescoping construction.
The receiver units 20A, 20B, 20C, 20D are affixed to the top end of each post 14FL, 14FR, 14BL, 14BR, respectively, of each end assembly 12F, 12B. The receiver units 20A, 20B, 20C, 20D provide a platform for the posts of the bed frame 2 to rest upon. The receiver units 20A, 20B, 20C, 20D also have barriers for inhibiting the movement of the legs 4 of the bed frame 2. The operation of the receiver units 20A, 20B, 20C, 20D is shown in further detail in
The posts 14FL, 14FR, 14BL, 14BR may be of square tubing as depicted in
The outside diameter of the support beam prongs 22A, 22B, 22C, 22D is smaller than the inside diameter of the support beams 18U, 18L such that they will fit one inside the other. The shape of the support beam prongs 22A, 22B, 22C, 22D does not have to match the shape of the support beams 18U, 18L. It is only necessary that the support beam prong 22A, 22B, 22C, 22D fit securely inside the support beams 18U, 18L. The support beam prongs 22A, 22B, 22C, 22D and the support beams 18U, 18L can be of any suitable cross section that facilitates the desired telescoping effect, such as circular, square or rectangular. In another embodiment of the present invention, the inside diameter of the support beam prongs 22A, 22B, 22C, 22D can larger than the outside diameter of the support beams 18U, 18L such that the support beams 18U, 18L fit inside the support beam prongs 22A, 22B, 22C, 22D.
The end assembly prongs 17A, 17B, 17C, 17D, 17E, 17F and the end assembly support beams 16A, 16B, 16C, 16D, 16E, 16F operate in a manner similar to the support beam prongs 22A, 22B, 22C, 22D and support beams 18U, 18L. The end assembly prongs 17A, 17B, 17C, 17D, 17E, 17F and end assembly support beams 16A, 16B, 16C, 16D, 16E, 16F need not be of the same diameter or cross section as the support beam prongs 22A, 22B, 22C, 22D and support beams 18U, 18L.
The end assembly support beams 16A, 16B, 16C, 16D, 16E, 16F also serve as steps for climbing the universally adjustable bed loft 10 to gain access to the bed frame 2. The end assembly support beams 16A, 16B, 16C, 16D, 16E, 16F can, therefore, include features to assist climbing, such as having a flat surface for squarely placing a foot or having the surface texture enhanced to facilitate gripping.
The attachment of the support beam prongs 22A, 22B, 22C, 22D and end assembly prongs 17A, 17B, 17C, 17D, 17E, 17F to the fist post 14FL and third post 14BL, and the attachment of the end assembly support beams 16A, 16B, 16C, 16D, 16E, 16F to the second post 14FR and fourth post 14BR can be achieved by using any suitable method. They may be permanently attached with welding methods or removably attached with a threaded fastener system or other mechanical system.

With this embodiment, the height of the universally adjustable bed loft 10 is adjustable. For the tallest height setting, all of the sections 24A, 24B, 24C, 24D, 24E, 24F, 24G, 24H, 24I, 24J, 24K, 24L can be used. For shorter settings, fewer sections 24A, 24B, 24C, 24D, 24E, 24F, 24G, 24H, 24I, 24J, 24K, 24L can be used.
The receiver unit 20A is comprised of a platform 28 and barriers 30. The area of the platform 28 is large enough to accommodate most any sized foot of a bed leg 4. In this embodiment, it is anticipated that the area of the platform 28 be larger than the area of the cross sectional area of the first post 14FL. The platform 28 is also generally flat to accept most bed legs 4A. The platform 28 may also be cupped or lipped for cradling the bed leg 4A. The platform 28 may also be slanted or indented to bias the bed leg 4A against the barrier 30. The platform 28 may also have cushioning material or enhanced surface features to provide a better grip between the platform 28 and bed leg 4A.
Movement of the bed leg 4A is restricted by barriers 30. The platform 28 may have barriers 30 that completely surround the bed leg 4A, or there may only be enough barriers 30 such that the bed frame 2 is immobilized by use of all four receiver units 20A, 20B, 20C, 20D. In one embodiment, as shown in
The barriers 30 should be of sufficient height to ensure immobility of the bed leg 4A during the normal course of usage of the universally adjustable bed loft 10, such as climbing and entering of the bed by a user. The barriers 30 may also have grip enhancing features as the platform 28 does. The receiver unit 20A may include additional features to further secure the bed leg 4A to the receiver unit 20A. For example, the barriers 30 may have holes to accommodate a bolt or screw to fasten the bed leg 4A to the barrier 30. Other clamping or banding means may also be used.
In another embodiment of the invention, the platform 28 is enclosed within the walls of the first post 14FL. The walls of the first post 14FL are then the barriers 30. Portions of the walls of the first post 14FL can be removed to allow for insertion of the bed leg 4A. The area of the platform 28 is then roughly the area of the cross section of the first post 14FL.
The embodiments in
A method for configuring the universally adjustable bed loft 10 to an existing bed frame 2 includes three basic steps. The first step is to assemble the two end assemblies 12F, 12B without locking them in place and then place them flat on the floor at either end of the bed frame 2. The width of the end assemblies 12F, 12B can be adjusted to the precise distance between the bed legs 4A, 4B, 4C, 4D while the end assemblies 12F, 12B are lying on the floor. The locking means 26 can then be engaged to fix the width of the end assemblies 12F, 12B. The second step is to place the two end assemblies 12F, 12B on their sides so that the support prongs 22A, 22B, 22C, 22D are lying along the floor at the ends of the bed frame 2 and connect the two end assemblies 12F, 12B with support beam 18U, 18L. Similar to the end assemblies 12F, 12B, the support beams 18U, 18L can be adjusted precisely to the length of the bed frame 2. The locking means 26 of the support beams 18U, 18L can then be employed to fix the length of the universally adjustable bed loft 10. The last step is to place the universally adjustable bed loft 10 in the upright position. Finally, the bed frame 2 can be set atop an upright universally adjustable bed loft 10.
Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
