Abstract: A system for producing adjustable articulated beds. These beds use measurements taken from a particular human form applied to the bed construction. All beds made using this system have the following in common: a standard distance of four inches from the top of the intended user's head to the head end of the mattress; a mattress that increases in length as the bed is articulated upward and decreases in length when returning to supine position thus matching the change that occurs to the posterior length of the user with no slippage; standardized articulating mechanisms, to articulate the thighs and legs plus and increases the length of the thigh supporting sections when articulated upward, thus matching the movement of the human form; and standardized orbiculators to articulate the torso.

Abstract: An adjustable bed having a bed frame, an assembly supported by the frame and including base and back portions, and a mattress foundation supported on the base and back portions. A motor when operated moves the back portion from a generally flat orientation to a raised orientation generally about a pivot axis and generally radially out from the pivot axis as it is pivoted to the raised orientation. The head end edge of the back portion travels generally in a vertical straight line up.

Abstract: An adjustable articulated bed manufactured in seven or so components for packing in three or so separate smaller boxes for easy transport. These components can be snap-fit together for easy assembly (and disassembly). The bed includes a bed frame, a power module or carriage and a bedding foundation. The foundation in turn includes a head portion and a body portion both of which are snap-fit securable in position to the power carriage. Pins releasably hold the roller assemblies of the power carriage to side rails of the frame for rolling moving of the carriage on the frame. A motor of the power carriage controllably moves the foundation head portion with respect to the frame and body portion. A drag link pivotally connects the head portion to the head rail of the frame. The drag link can be releasably connected at either end thereof or in the middle, snapping the two parts of the drag link together.

Abstract: An adjustable articulated bed including a bed foundation having a body member and a generally separate head member, a mattress supported on the foundation, an electrical motor coupled to the head member, and a support frame which supports the mattress, foundation and motor. The motor when operated pivots the head edge of the head member upwardly, moves the head member away from the body member along a roller-glide assembly, and together with the pivoting motion moves the entire foundation towards the head edge of the frame. Thereby, the head portion of the mattress does not slide with respect to the foundation head member and the head edges of the mattress and foundation travel up in a vertically straight line thereby remaining in constant close proximity to the wall at the head edge of the bed. Advantageously, the person lying on the bed experiences a similar movement; that is, his shoulders move in a straight vertical line.

Abstract: A lamp mounting structure for use in recessed lighting fixtures comprises a planar portion having an illumination aperture over which a translucent plate may be removably retained. A lamp may be removably retained over said aperture by resilient tabs which extend inwardly beyond the edges of the aperture so as to engage the lamp whether or not such a translucent plate is interposed between it and the planar portion of the lamp mounting structure.

Abstract: A safety device for an adjustable bed having an articulated mattress is shown including a power drive module having adjustable sections that support corresponding sections of the articulated mattress. Multiple winding electrical motors are mounted within the drive module for driving the adjustable sections through linkages. Due to the weight of the articulated mattress and adjustable section, the linkages are always in tension. However, should a foreign object, such as a hand, be placed below the mattress supporting section as it is lowered, the linkage will be exposed to a compression force. A switch is mounted within the linkage to sense the compression force and inhibit the motor winding which lowers the bed. However, the winding which raises the adjustable bed continues to be enabled to permit the bed to be raised and the foreign object removed.

Abstract: An adjustable bed is shown having an adjustable frame which supports an articulated mattress. The frame mounts a single motor which lifts a first adjustable section thereof through a threaded drive shaft. A push linkage connects from the first adjustable section of the frame back to the frame itself where a conversion plate connects the push linkage to a pull linkage. The pull linkage connects to a second adjustable section of the frame. The single motor thus raises the first adjustable section and, through the linkage, the second adjustable section.

Abstract: An adjustable articulated bed which may be disassembled for easy shipping in a small container and which is constructed from a minimum number of components is shown. The bed includes a frame, power drive module which nests within the frame and an articulated mattress. In one embodiment, the power drive module includes all necessary moving parts to form the articulated bed so that any frame may be used. In another embodiment, the power module includes all moving parts but for a pivotal linkage which mounts between the lower leg section of the articulated mattress and the frame. In either embodiment, the power module includes a pair of central support members which are separated by a lateral support. The lateral support is provided with a square cross section that aligns the central support members and drive motors mounted thereon. The pivot points are arranged in the two planes formed by the central support members for increased strength.
