Modular user-assembled adjustable, and high-low adjustable beds

Abstract

In an adjustable bed having juxtaposed between a mattress and a floor an articulated frame, and one or more wired motors operating on the articulated frame so that the mattress resting atop the frame is adjusted in contour, the articulated frame is modular, and ships in two or more modular frame sections each of which is sufficiently small so as to fit upon a standard shipping pallet of 48 by 48. Moreover, and further, the two or more modular frame sections semi-permanently engage by sliding protrusionspreferably steel tubesextending from spaced-parallel frame rails of a one section into a complimentary cavities of the frame railspreferably steel tubes of square cross sectionof a next frame section. This sliding assembly may be done by one adult man, without use of tools. The extensive contact between the telescoping members makes that the connection, and the modular adjustable bed itself, is suitably strong.

3. The adjustable bed of claim 1, wherein the head section of the articulated frame further comprises two longitudinal frame rails separated by at least two lateral members extending between the two longitudinal frame rails.

4. The adjustable bed of claim 3, wherein the foot section of the articulated frame further comprises two longitudinal frame rails separated by at least two lateral members extending between the two longitudinal frame rails; and wherein the first floating inner tube and the second floating inner tube each further comprise a nose combined to an end thereof, and wherein the nose of the first floating inner tube guides a portion of the first floating inner tube into the corresponding sleeve of the pair of sleeves of one of the head section and the foot section, and wherein the nose of the second floating inner tube guides a portion of the second floating inner tube into the corresponding sleeve of the pair of sleeves of one of the head section and the foot section.

5. The adjustable bed of claim 4, wherein each of the first floating inner tube and the second floating inner tube further comprises a first spring pin, and wherein each of the pair of sleeves on the longitudinal frame rails of the foot section have a hole, and wherein the first spring pin of the first floating inner tube and the first spring pin of the second floating inner tube each selectively engages the respective hole to selectively hold each of the first floating inner tube and the second floating inner tube extending from a cavity of the sleeve.

6. The adjustable bed of claim 5, wherein each of the first floating inner tube and the second floating inner tube further comprises a second spring pin, and wherein each of the pair of sleeves on the longitudinal frame rails of the head section have a hole, and wherein the second spring pin of the first floating inner tube selectively engages the hole of each of the pair of sleeves on the one of longitudinal frame rails of the head section and the second spring pin of the second floating inner tube selectively engages the hole of the other sleeve of the pair of sleeves on the other longitudinal frame rail of the head section to combine the first floating inner tube and the second floating inner tube with the head section.

7. The adjustable bed of claim 1, wherein a nose on each of the first floating inner tube and the second floating inner tube has a bull-nose shape to guide the respective first floating inner tube and the second floating inner tube into the corresponding sleeve of the pair of sleeves of either the head section or the foot section.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a diagrammatic perspective view of a base portion of a preferred embodiment of the modular adjustable bed of the present invention, the portion shown being without motors and wiring.

(2) FIG. 2 is a diagrammatic perspective view of the base portion of the preferred embodiment of the modular adjustable bed of the present invention, previously seen in FIG. 1, now split into it head and foot sections that are each boxed and shipped separately, and later assembled together by a purchaser-user without use of tools.

(3) FIG. 3, consisting of FIG. 3a and FIG. 3b, are detailed plan views showing the telescoping attachment mechanism of the heat and foot sections of the partial preferred embodiment of the modular adjustable bed of the present invention, previously seen in FIGS. 1 and 2.

DESCRIPTION OF THE PREFERRED EMBODIMENT

(4) A diagrammatic perspective view of base portion 1 of a preferred embodiment of a modular adjustable bed of the present invention, this base portion 1 being shown being without associated motors and wiring, is contained in FIG. 1. Another diagrammatic perspective view of this same portion 1, now split into a head section 11 and a foot section 12 (that are each boxed and shipped separately, and later assembled together by a purchaser-user without use of tools) is shown in FIG. 2. The portion 1 is substantially constructed of square cross section steel tube. Various attachment points are presented at which the pivoting bed surfaces, and the motors, of the adjustable bed may be conventionally attached.

(5) In accordance with the present invention, two bull-nosed inner tubes 121a, 121b (best seen in FIG. 2) extend from spaced-parallel foot frame section 12 towards corresponding cavities in the complimentary spaced-parallel frame rails 112a, 112b of the head frame section 11. The protruding inner tubes 121 a, 121 b slide longitudinally into the opposed cavities of the head frame section frame rails 112a, 112b, semi-permanently joining the two, head and foot, frame sections 11, 12. The fit is snug, and the connection strong, but the union may readily be accomplished under force of the hands and arms of an adult man.

(6) Detailed plan views showing the telescoping attachment mechanism of the head and foot sections 11, 12 of the partial preferred embodiment of the modular adjustable bed of the present invention are shown in FIGS. 3a and 3b. FIG. 3b is a cut-away cross sectional view taken along aspect line 1-1 of FIG. 3a.

(7) A plastic noseof which nose 121 b of inner tube 121 b is shownon each of the inner tubes 121 a, 121 b serves to guide each tube into the cavity of head section frame rail tubes 112a, 112b. A bolt, of which bolt 123b shown in FIG. 3b is exemplary, may be dropped into holes that become aligned upon sliding connection of the frame rails, therein to strongly hold the sections together. All bolts may be removed from disassembly.

(8) The head and foot sections 11, 12 of the base of the preferred embodiment of the modular adjustable bed of the present invention are the largest sections of the bed. Other parts and sections, such as the planar sections that comprise the sleeping surface of the bed, the motors for the bed and their wiring harness, and the controls for the bed, are all smaller, and lighter, than are the head and foot sections 11, 12. Moreover, it is the interlocking between the head section 11 and the foot section 12 that, in particular, provides strength, stability, and durability to the adjustable bed. Accordingly, the gravamen of the present invention will be found within the quality affixation and union, achieved without tools, of the head and foot sections 11, 12, and it will be understood that beds and adjustable beds of standard design may readily be affixed to the illustrated modular base by practitioners of the design of mechanical beds.

(9) According to these variations, and still others within the skill of a practitioner of the art of design of mechanical beds, and adjustable beds, and modular adjustable beds, the present invention should be considered in accordance with the following claims, only, and not solely in accordance with that particular embodiment within which the invention has been taught.
