## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to vibrating beds and, more specifically, to an undulating bed that provides an undulating/rocking motion from side to side and/or front to back. Most beds that provide motorized stimulation utilize vibration to stimulate the user. The present invention provides a plurality of U-shaped springs constrained by spring rails connected through adjustable linkage arms to pivot plates driven by variable RPM motors to create an undulating/rocking side-to-side and/or front to back movement to substantially simulate motion experienced on a boat as a sleep aid to a user.
2. Description of the Prior Art
There are other motorized devices for beds. While these devices may be suitable for the purposes for which they where designed, they would not be as suitable for the purposes of the present invention as heretofore described.
SUMMARY OF THE PRESENT INVENTION
A primary object of the present invention is to provide an undulating bed comprising a bed frame support and padded mattress with an internal spring frame incorporating a plurality of U-shaped springs constrained by two spring frame rails having a free sliding curved member fastened between the spring frame rails supported on a structural frame curved surface support of the bed frame support and a bed frame, housing a pair of variable RPM motors with one motor having adjustable linkage arms exerting a side-to-side force on the padded mattress spring frame rails and the other variable RPM motor having adjustable linkage arms exerting a force fore-to-aft on a front and rear U-shaped spring, so that when the variable RPM motors are energized the padded mattress is provided with undulating/rocking motions likened to the movement experienced on a boat that is intended as a sleeping aid for users.
Another object of the present invention is to provide an undulating bed wherein the spring frame provides a plurality of transverse U-shaped springs beneath the padded mattress.
Yet another object of the present invention is to provide an undulating bed wherein the spring frame further provides a plurality of coil springs fixedly attached onto top portions of the plurality of transverse U-shaped springs serving as the typical mattress spring support.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The following discussion describes in detail one embodiment of the invention. This discussion should not be construed, however, as limiting the invention to those particular embodiments, practitioners skilled in the art will recognize numerous other embodiments as well. For definition of the complete scope of the invention, the reader is directed to appended claims.
Referring to FIG. 1, shown is an isometric view of the present invention in use. The present invention is an undulating bed 10 for simulating an undulating/rocking motion experienced on a boat, which will serve as a sleep aid to a user 12. The undulating bed 10 comprises a padded mattress 14 that sits atop a bed frame support 16. The padded mattress 14 encompasses a spring frame 18 connected through adjustable linkage arms 20 to variable RPM motors 22 housed with the bed frame support 16. The adjustable linkage arms 20 connect to the spring frame 18 in transverse and longitudinal fashion, thereby imparting the undulating/rocking motion to the padded mattress 14.
Referring to FIG. 2, shown is an exploded isometric view, with parts shown in phantom, of the present invention. The undulating bed 10 comprises the spring frame 18 and the bed frame support 16. The spring frame 18 has a pair of spring frame rails 24 with spaced apart apertures 26, each having a plurality of elastic bands 28 fastened under the apertures 26. A plurality of U-shaped springs 30 are also provided, having coil springs 32 fastened onto top portions 34, forming typical user support with leg portions 36 positioned within the spring frame rail apertures 26 and supported by the elastic bands 28. Fastened between the spring frame rails 24 is a free sliding curved member 38 that sits on a structural frame curved surface support 40 of the bed frame support 16. The bed frame support 16 comprises a bed frame 42 and the structural frame curved surface support 40, with the bed frame 42 housing the variable RPM motors 22 connected to pivot plates 44. The adjustable linkage arms 20 are fastened to the spring frame rails 24 and front and aft U-shaped springs 30, thereby simulating the undulating/rocking motion experienced on a boat.
Referring to FIG. 3, shown is an assembled isometric view, with parts shown in phantom, of the present invention. The undulating bed 10 has the padded mattress 14 incorporating the spring frame 18, which is comprised of the plurality of U-shaped springs 30 constrained within apertures 26 of spaced apart spring frame rails 24 and is supported therein by a plurality of elastic bands 28 fastened under each of the spring rail apertures 26. Fastened between the spring frame rails 24 is the free sliding curved member 38 that sits on the structural frame curved surface support 40 of the bed frame support 16. Also attached to the spring frame rails 24 is an adjustable linkage arm 20, extending to the pivot plate 44 driven by the first variable RPM motor 22 with the pivot plate 44 providing side-to-side reciprocating motion for the spring frame rails 24, resulting in an undulating motion imparted on the U-shaped springs 30. The second variable RPM motor 22 is also connected through an adjustable linkage arm 20 to fore and aft U-shaped springs 30, thereby generating an undulating motion fore-to-aft. When the variable RPM motors 22 are simultaneously energized, the pivot plates 44 and adjustable linkage arms 20 produce the undulating/rocking motion, thereby emulating motion similar to that experienced on a boat with such motion intended as a sleep aid. The first pivot plate adjustable linkage arm 20 comprises tension rods 46 and elastic members 48 fixedly attached to the respective spring arm rails 24.
Referring to FIG. 4, shown is a cross sectional view of the present invention. The undulating bed 10 provides the padded mattress 14, housing an assembly of U-shaped springs 30 slidably movable via the pair of spring frame rails 24 reciprocated by variable RPM motors 22. The variable RPM motors 22, located within the bed frame 32, are connected to a gearbox 50 that drives a respective pivot plate 34 and adjustable linkage 20 having adjustable tension rods 46 incorporating elastic members 48. The adjustable tension rods 46 are fastened to the spring frame rail 24 on the left and right, providing lateral movement while the other adjustable tension rods 46 are fastened to a front U-shaped spring 30 and a back U-shaped spring 30 providing fore to aft motion. Working simultaneously, the movement simulates that is experienced on a boat with such movement intended as a sleep aid. A controller 54 energizes and de-energizes the variable RPM motors 22. The controller 54 contains a switch 56 to vary the RPM speed of the variable RPM motors 22.
Referring to FIG. 5, shown is an exploded cross sectional view of the present invention. The undulating bed 10 provides the padded mattress 14 housing an assembly of the U-shaped springs 30 slidably movable within the spring frame rails 24 reciprocated through linkage arms via variable RPM motors 22. The variable RPM motors 22, located within the bed frame 16 are connected through gear boxes 50, driving the pivot plates 44 having the adjustable linkage arms 20. One adjustable linkage arm 20 is connected transversely providing side-to-side motion, while the other is connected longitudinally to a front U-shaped spring 30 and a back U-shaped spring 30, providing fore-to-aft motion, so that simultaneously energizing both variable RPM motors 22 will provide an undulating/rocking motion simulating that is experienced on a boat, which is used as a sleep aid.
Referring to FIG. 6, shown is an elevational view, with parts in section, of a mattress support coil spring of the present invention. The mattress support coil spring 32 is used in the plurality as typical user support springs within the padded mattress 14.
Referring to FIG. 7, shown is a top view of some of the mattress support coil springs positioned on the U-shaped springs. The coil springs 32 are fixedly attached onto the respective top portion 34 of the U-shaped springs 30.
Referring to FIG. 8, shown is an isometric view of a portion of one spring frame rail constraining the leg portions of the U-shaped springs. The spring frame rail 24 has apertures 26 for receiving the leg portions 36 of the U-shaped springs 30 with the elastomeric or polymeric members 52 positioned across the base of each rail aperture 26, thereby individually supporting each of the leg portions 36 of the U-shaped springs 30.
