DETAILED DESCRIPTION

[0021] While this invention is susceptible of embodiments in many different forms, there are shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.

[0022] Referring to the figures, a motorized bed 10 comprises a base frame 14 and an articulating frame 100. One of ordinary skill in art is familiar with this arrangement wherein the articulating frame 100 is movable relative to the base frame 14.

[0023] The base frame 14 is provided with opposing guide rails 18.

[0024] The articulating frame 100 includes a linking frame 104 movably mounted on the base frame 10, a first support frame 108 is pivotally attached to the linking frame 104, support members or beams 112 pivotally join the base frame 10 with the articulating frame 100 via a padded member (not shown), which is joined to the first support frame 108, a second support frame 116 is pivotally joined to the linking frame 104, a third support frame 120 is pivotally mounted to the second support frame 116, additional support beams 124 pivotally join the linking frame 104 with and the third support frame 120.

[0025] The linking frame 104 is outfitted with rollers 126 which extend downwardly. The rollers 126 are received within the opposing guides of the base frame 14 and traverse therein.

[0026] Typical furniture drive motors 128 are pivotally joined to the linking frame 104. These furniture drive motors 128 include a cylinder which extends from a housing in response to an electrical signal and are well known in the art of motorized beds. Opposing ends of each drive motor 128 are pivotally joined to ends of shaped beams or actuator brackets 132. Opposing ends of the actuator brackets 132 are attached to the first support frame 108 and the second support frame 116, respectively.

[0027] The articulating frame 100 further includes a mattress backing 200. The mattress backing has an upper surface 202 on which a mattress (not shown) is supported and an opposite lower surface 204. The mattress backing 200 comprises a plurality of separate panels 208a-d which are supported above the articulating frame 100 by the first support frame 108, the linking frame 104, the second support frame 116, and the third support frame 120, respectively and moving in a direction from a head end of the motorized bed 10 to a foot end of the motorized bed 10. The panels 208a-d are attached to their respective frame members. The panels 208a-d are produced from a substantially rigid material, primarily a wood. One or more of the panels 208a-d has an aperture 212 therein through which a portion of a vibration motor assembly 300 passes. The vibration motor assembly 300 comprises an electric massage or vibration motor 304, a motor mount 308, a cushion 312, and an assembly cover 316.

[0028] The massage or vibration motor 304 is of a type known on the art. It comprises a motor housing 320 and a flange 324. The motor housing 320 has a curved surface, a major portion of a sidewall of which may be a portion of a right circular cylinder truncated by, or resting on, a plane defined by an upper surface 328 of the flange 324, which upper surface 328 itself is truncated or interrupted by its intersection with the housing 320. The flange 324 is outfitted with a plurality of through holes to accommodate fasteners 332 which attach the vibration motor 304 to the motor mount 308. An example of a suitable massage motor 304 is the motor marketed under the name HJM2 by Qingdao Richriver Electrics Co., LTD.

[0029] The motor mounts 308 are used to attach vibration motors 304 to the articulating frame 100. More specifically, a plurality of vibration motors 304 are attached to the panels 208a-d, one vibration motor 304 per panel 208a-d. The motor mounts 308 comprise flexible brackets 336. Fasteners 340 attach the flexible brackets 336 to the lower surface 204 of the articulating frame 100 which corresponds to lower surfaces of the panels 208a-d. The fasteners 340 are preferably wood screws, lag screws, or the like. However, one skilled in the art would readily recognize that the preferred choice of fastener 340 would be primarily dictated by the material to which the flexible brackets 336 are attached. Thus, any type of chemical or mechanical fastener that is compatible with both panels 208a-d and the flexible brackets 336 may be employed. In the preferred embodiment, the panels 208a-d are produced from a wood.

[0030] As best illustrated in FIG. 9, the flexible brackets 336 are produced from a pliable material that is fully flexible at room temperature. The flexible brackets 336 are preferably formed from a fabric, more preferably a fabric of woven strands or strands that is strong enough to support and retain the vibration motors 304 in a desired position relative to the apertures 212 in the panels 208a-d. The strands can be natural but are preferably produced from a polymeric material with an elastic quality that allows the flexible brackets 336 to expand and return to their original dimensions under the forces experienced during intended use.

[0031] The flanges 324 of the vibration motors 304 are attached to the flexible brackets 336 using fasteners 332, and the flexible brackets 336 are attached to the lower surfaces of the panels 208a-d. This arrangement allows the housing 320 of each vibration motor 304 to be oriented upwardly and extend into a corresponding aperture 212 with the flange 324 oriented downwardly relative to the lower surface of the panel. The housing 320 preferably extends into and through the aperture 212 and upwardly such that a portion of the motor housing 320 extends above a plane defined by the upper surface 202 of the mattress backing 200. Thus, the vibration motors 304 are suspended from the lower surface 204 of the mattress backing 200 wherein the flexible brackets 336 are deflectable such that the vibration motors 304 are movable within the aperture 212.

[0032] The motor assemblies 300 further comprise cushions 312 which preferably substantially surround the housings 320 within the apertures 212 such that a portion of each cushion 312 is located between the housings 320 and the mattress backing to prevent contact of the housings 320 with sidewalls 220 of the mattress backing 200 that define an aperture 212 shape the within the aperture and between vibration motor and the mattress backing 200. The cushions 312 are preferably produced from a foam material.

[0033] Covers 316 are provided to conceal and protect vibration motors 304. The covers 316 are generally produced from a fabric and attached to the lower surface of the articulating frame 100 via hook and loop fasteners. The covers 316 preferably fully conceal the vibration motors 304 and the apertures 212.

[0034] As illustrated best in FIGS. 1, 8 and 9, the upper surface 202 of the mattress backing 200 can have a padding 250 supported thereon. The padding 250 covers the apertures 212 and the motor assemblies 300, providing a barrier between a mattress (not shown) and the panels 208a-d.

[0035] The motorized bed 10 may further comprise a mattress retainer 400 as illustrated in FIG. 1. The mattress retainer 400 prevents a mattress (not shown) from unwanted movement from the foot of the bed frame 10.

[0036] While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention, and the scope of protection is only limited by the scope of the accompanying Claims.
