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

Abstract

A frame for an adjustable has a head section with two longitudinal frame rails separated by at least two lateral members extending between the two longitudinal frame rails, and two sleeves each having a cavity with one of the two sleeves on each of the two longitudinal frame rails. The frame has a foot section having two longitudinal frame rails separated by at least two lateral members extending between the two longitudinal frame rails, and two sleeves each having a cavity with one of the two sleeves on each of the two longitudinal frame rails, and an inner tube with a nose for each of the two sleeves and for moving between a first position retracted in the cavity of the sleeve and a second position extending from the cavity of the sleeve.

Claims

1. A frame for an adjustable bed comprising: a head section having two longitudinal frame rails separated by at least two lateral members extending between the two longitudinal frame rails, and two sleeves each having a cavity with one of the two sleeves on each of the two longitudinal frame rails; a foot section having two longitudinal frame rails separated by at least two lateral members extending between the two longitudinal frame rails, and two sleeves each having a cavity with one of the two sleeves on each of the two longitudinal frame rails, and in each sleeve a floating inner tube that is articulable in a transverse and lateral manner within both the sleeve of the foot section and the sleeve of the head section to guide each floating inner tube into the corresponding sleeve of the head section to combine the foot section and the head section, and each floating inner tube is movable for each of the two sleeves of the foot section and for moving between a first position retracted in the cavity of each of the two sleeves of the foot section and a second position extending from the cavity of each of the two sleeves of the foot section; and wherein the foot section is selectively combined with the head section with a portion of each inner tube of the longitudinal frame rails of the foot section positioned in each sleeve of the longitudinal frame rails of the head section to selectively combine the head section and the foot section.

2. The frame of claim 1, wherein each inner tube further comprises a first spring pin, and wherein each of the two sleeves on the longitudinal frame rails of the foot section have a hole, and wherein the first spring pin of each inner tube selectively engages the hole to selectively hold each inner tube in the second position extending from the cavity of the sleeve.

3. The frame of claim 2, wherein each inner tube further comprises a second spring pin, and wherein each of the two sleeves on the longitudinal frame rails of the head section have a hole, and wherein the second spring pin of each inner tube selectively engages the hole of the sleeve on the longitudinal frame rail of the head section to combine each inner tube with the head section and simultaneously the first spring pin of each inner tube engages the hole in the sleeve on the longitudinal frame rail of the foot section to hold each inner tube in the second position extending from the cavity of the sleeve so that each inner tube simultaneously combines the head section and the foot section.

4. The frame of claim 3, wherein the first spring pin on each inner tube is bulbous-nose in shape and extends under spring force transversely to each inner tube in a region of each inner tube that is inserted into the sleeve on the longitudinal frame rail of the foot section, and wherein the second spring pin on each inner tube is bulbous-nose in shape and extends under spring force transversely to each inner tube in a region of each inner tube that is inserted into the sleeve on the longitudinal frame rail of the head section.

5. The frame of claim 4, wherein the foot section with each inner tube in the first position is sufficiently small as to fit upon a standard shipping pallet of 48″ by 48″.

6. The frame of claim 5, wherein the head section is combined to the foot section without the use of tools.

7. The frame of claim 1, wherein each inner tube has a bull-nose to guide each inner tube into the corresponding sleeve on the longitudinal frame rails of the head section.

8. The frame of claim 1, wherein each inner tube floats in the corresponding sleeve on each of the two longitudinal frame rails of the head section and 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 121a, 121b slide longitudinally into the opposed cavities of the head frame section frame rails 112a, 112b, semipermanently 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 nose—of which nose 121b of inner tube 121b is shown—on each of the inner tubes 121a, 121b 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.
