Adjustable angle bed frame
An “L-shaped” bed frame assembly, where the head end of the frame is taller than at the foot end, constructed in a manner which enables the user to raise the head of the bed frame by an electric motor, rising up along the taller “rail” at the head of the frame, adjusting the frame to any reasonable angle, while the frame remains flat—not bending in the middle like the older “hospital bed” style—constructed of either the traditional L-shaped flatiron, or a more tubular structural material.
This application claims priority benefit of a U.S. Provisional Application, Ser. No. 60/922,702 filed in the United States Patent and Trademark Office on Apr. 10, 2007 and entitled “Adjustable angled bed frame”.

BACKGROUND OF THE INVENTIONA. Field of the Invention
This invention relates to bed frames and, more specifically, to the class of bed frames that are adjustable, thereby, allowing the user to adjust the bed frame to any reasonable angle. Most adjustable bed frames are designed to operate like the “hospital bed” type frame, raising and positioning the head and shoulders near the head end of the bed and raising and positioning the lower extremities at the knee level. This requires that the mattress and mattress foundation be able to “break”, hinge or bend in one or two places—one in the general area of the user's hips, the other in the general area of the user's knees.
B. Prior Art
The history of adjustable bed frames is deep. However, most adjustable bed frames are of the “hospital bed” type whereby the bed frame can be raised at the head and shoulder level, creating a break in the center of the mattress. Most “hospital bed” type adjustable designs also allow the bed frame to be raised at knee level.
U.S. Pat. No. 3,031,689 issued on May 1, 1962 is one of these devices that elevate the head/shoulders using a pad fixed to one end of a threaded rod that is operated manually to adjust the frame.
U.S. Pat. No. 6,874,178 filed on May 7, 2003 utilizes a “frame-within-a-frame” concept. Yet the bed frame still raises the head and shoulders area causing the mattress to fold in the middle as illustrated in
U.S. Pat. No. 4,084,872 filed on May 9, 1978 provides a titling of the bed at either the head or the foot ends. However, this invention utilizes far more moving parts and electric motors adding unnecessary weight and complex assembly. In addition, this invention does not offer the same quality of sturdiness and support.
BRIEF SUMMARY OF THE INVENTIONAn object of this invention is to provide a bed frame that is a simple departure from “hospital bed”—type frames and other more complicated frames that enable the user to tilt the bed frame at its head end, providing an incline of the bed while allowing the mattress to remain flat.
A primary object of this invention is to provide a home user with an inexpensive, yet truly effective apparatus which provides simple user adjustment of his mattress inclination angle in a residential setting.
A further object of the invention is to provide a light-weight adjustable frame that is less expensive to ship, easier to assemble and easier to maintain.
A further object of the invention is to provide a bed frame that can incline to any reasonable angle using a simple electric motor at the head end of the frame, controlled by the user with an infrared, laser, Bluetooth or radio frequency remote control device.
A further object is to provide an inclined and adjustable bed frame that, when raised, allows the mattress and box spring it supports, to clear and not interfere with the footboard.
A further object is to provide an adjustable bed frame that will attach to any conventional headboard or footboard, of any conventional bed size (single, double, twin, queen, king, etc.)
Another object is to provide an adjustable bed frame specifically designed to be used in the home, offering a more basic functionality for simply lifting and lowering the entire frame at the head end of the bed frame while keeping the foot end of the bed frame practically stationary.
Yet another object is to provide an adjustable bed frame that allows the user to incline the bed frame, relative to the supporting floor, while allowing the mattress and box spring foundation to remain flat.
Still another object is to provide an adjustable bed frame whose construction enables the bed frame to incline using fewer moving parts, fewer motors or cranks, rendering it lighter in weight and maximizing ease of assembly and maintenance.
Therefore, the objective of this invention is to provide the user with a simple and basic mechanism to easily lift and lower the head end of their bed so the bed can be used at any reasonable angle to improve the quality of sleep.
The design and structure of this invention is applicable to any conventional size bed frame (single, double, twin, queen, king and California king) and is designed to connect to any conventional headboard or footboard.
Thus, the bed-frame enables the bed to be raised in a single motion to a variable increased angle, while allowing the bed frame and the mattress to stay flat. The integrated “gliding channels” allow the inner frame to rise at the head end, while allowing the foot end to move slightly toward the head end, thereby, preventing the box spring and mattress from coming in contact or interfering with the footboard.
The advantages and features discussed above and other advantages and features will become apparent from the detailed description of the best mode for carrying out the invention that follows.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention:
In the drawings:
Detailed reference will now be made to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Referring to
This bed frame invention is constructed of either a light-weight, square tubular metal material—the more conventional L-shaped flatiron used today, aluminum tubing, high strength composite tubing or materials, or another ridged, light-weight material to be determined in the future.

At the head end 18 of the bed frame 10 structure is the distinguishing head end riser 20, which forms the frame's L shape, affixed to the base of the bed frame 10 perpendicularly. It is along this axis that the head end 18 of the inner frame 14 is raised and lowered by an electric motor, shaft and support structures (see

The shaft 40 is attached directly to the middle of the inner frame 14 and to the outer edges of the inner frame 14 by support arms 42. This assembly provides the needed support to raise and lower the head end 18 while providing stability at any height or angle. The user can raise the head end 18 of the inner bed frame 14 from one to approximately twelve inches, or any increment therein.
Though other bed frames provide various forms of adjustable tilting, this adjustable bed frame 10 enables a bed to be tilted by raising the head end 18 with far fewer movable parts and far fewer motors and gears than previous inventions in the field.
This bed frame 10 also compensates for the depth of the mattress 28 and boxspring 29 set, when the head end 18 is raised, to avoid interfering with the footboard 26. Furthermore, the design is capable of attachment to any standard headboard 24 and footboard 26. The bed frame 10 may be constructed of a square, tubular-shaped metal or the more common L-shaped flatiron thus making the bed frame lighter in weight and easier to assemble than previous inventions in the field. Aluminum tubing or other high strength metals or composite materials may be used individually or in combination as well for the bed frame 10 or other support components.

The outer frame 12 is supported by four adjustable footers 16. Reference is made to FIGS. 2 and 3A-C. Footer unit 16 is supported by an adjustable screw-type bolt which, in turn is connected to a footer-pad. This mechanism allows the bed frame to be adjusted so it is level to the floor or can compensate for a non-level floor.
As illustrated in
The inner frame 14 is attached to the outer frame 12 by rollers 32. Rollers 32 at the head end 18 attach the inner frame 14 to the L-shape riser 20 via the glide channels 30 enabling it to slide up and down inside the riser 20. The inner frame 14 is attached to outer frame 12 at the foot end 34 by the rollers 32 such that when the head end 18 of the bed frame rises, the foot end 34 stays at the same level as the outer frame 12 but is allowed to travel slightly toward the head end 18 of the frame 12 via the foot end 34 rollers 32 which are attached to gliding channel 30. This dynamic also prevents the mattress set from interfering with the attached footboard.
A further embodiment would include the use of a waterbed mattress. Recent improvements in mattress construction include separate internal compartments and baffles such that a waterbed mattress can be inclined in the same manner as described above for conventional mattresses. The baffles and sealed inner compartments keep the water in the desired locations and prevent such from surging into the lower or foot end of the bed. The frame components including the structure and motor components are functionally the same except they are designed to accommodate higher loads due to the weight of the mattress.

Referring now to FIGS. 14,a remote control unit 80 for the ‘Ribbon Bed’ is shown. It includes a visual display 82 which communicates the inclination angle of the bed frame to the viewer. The remote control allows the user to adjust the bed to the precise sleeping angle to fits his unique needs. The remote is also designed to recall specific inclination angles of the user or users in its electronic memory. Thus one click of a ‘memory’ button 84 will command the inner frame to a predetermined angle for the user. Built in weight on bed sensors 84 (see
Sleeping at a slightly inclined angle is healthier and more comfortable. It more evenly distributes your weight reducing pressure points that can cause back pain. Doctors know that clearer airways and a slightly inclined position dramatically reduces or eliminates snoring. A slightly inclined sleeping angle enables better circulation, therefore reducing or eliminating facial puffiness in the morning. When you lay completely flat, your sinuses have a greater tendency to clog. At a slight incline, airways stay clear
Many people, even younger people complain of acid reflux especially when they're trying to sleep, but increasing the angle of the bed just a few degrees can relieve the burning feeling of acid reflux.
