Description
CONV~RTIBLE BED CHAIR
Back~round of the Invention Field of the Invention:
This inven-tion rela-tes to convertible chairs of'-the -type using the seat and back cushions to form a horizontal bed.
Description of the Prior Art:
Prior art devices have used a number of different ways to position cushions in horizontal alignment to form a bed.
See for example U.S. Patents 3,867,730 o~ February 25, 1975 to J. Wright; 4,292,697 of Oct. 6, 1981 to A. Alembik;
4,343,508 of Aug. 10, 1982 to D. Heling; 4,378,609 of April 5, 1983 to C. Patterson.
In U.S. Patent 3,867,730, a base frame 10 attached to spaced arms supports three interconnected frame sections, one of which has stringers 21 thereunder and a transverse support member at its forward edge. The stringers slidably engage the base frame.
In the present invention, there are only the spaced arms, a pair of spaced crossbars connecting the arms and a movable seat structure having wheels which is movable into and out of the space between the arms.
~1 f~3 ~ device similar to tha-t of Paten-t 3,867,730 is found in Patent 4,292,6g7 and again in Patent ~,3~3,508.
Patent 4,343,508 has a tubular metal frame supporting a back and seat with a bed extension hinged to the back and movable outwardly away from the seat to form a bed. Folding legs are provided to support the bed extension.
Patent ~,37~,609 disclosures a device comparable with that of Patent 4,3~3,508 except that the bed extension moves forwardly of the device which has a frams formed of a pair of spaced arms, a back portion interconnecting the arms and a comparable front portion interconnecting the arms over which the seat portion is elevated by levers and moved upwardly and outwardly over the same to a bed configuration. None of these prior art patents disclose a simple, inexpensive, novel arrangement of the pair oi spaced arms, the pair of crossbars interconnecting the same and a wheeled seat portion movable generally horizontally in and out of the space between the arms with a portion of the seat portion moving inunder the crossbars and a portion moving over the same.
~pplicant's~convertible bed chair mounts a flat cushion support ~rame on the wheeled support and another on one of the ~2~
crossbars with an intermediate Lrame pivo-ted therebetween and slidably secures a cushion on said cushion support frame.
Descri~tion o~ the Dra~in~rs Figure 1 is a vertical section of -the convertible bed chair in chair configuration with one o~ the arms removed;
Figure 2 is a vertical section o~ the convertible bed chair in a partially open configuration;
Figure 3 is a vertical section of the convertible bed chair in open-bed configuration;
Figure 4 is a top plan view of the convertible bed chair with parts broken away;
Figure 5 is an enlarged de-tail o~ a hinge connecting two of the flat frame portions seen in Figures 1-3; and Figure 6 is an enlarged vertical section o~ a portion o~
the convertible bed chair as seen in Figures 1-3.
Descri~tion of the Preferred Embodiment As seen in Figures 1,2 and 3 o~ the drawings, the con-vertible bed chair comprises a pair of spaced vertically standing arms 10 having front and back portions and each having a pair of feet. Two horizontally spaced transversely extending crossbars 11 are attached at their respective ends to metal plates 12 which in tuln are attached -to the inner sides oI the arms 10 an~ more particularly to reinl'orcing members therein. The croæsbars 11 are the only structure connecting the arms 10 of the conver-tible bed chair. A pair of angularly disposed tubular socke-ts 13 are affi~ed to one of the crossbars 11 and removably receive pins l~ which are pivotly secured by pivots 15 to members 16 which are in turn attached to the opposite lower sides of a firs-t flat frame 17, a].l as best illustrated in ~igure 6 of the draw~
illgS.
The first flat frame 17 is tubular, substantially square in shape, and is hingedly affixed by hinges 18 to a second flat frame 1~ which is formed of tubular members and is also substantially square shaped which in turn is hingedly affixed by hinges 20 to a third flat frame 21 which is formed of tubular members and is of substantially square shape. The third flat frame 21 is pivotally attached by pivots 22 to a horizontally spaced pair of horizontally disposed frames 23 which are integrally formed with vertical frames 24 which in turn are integrally formed with a lower pair of horizontal frames 25. It will be seen that the frames 23, 2~, and Z5, which are interconnected by a crossframe 26 which extends between -the lower horizontal frame members 25 and a -transverse:Ly pos:Ltioned rectangularly shaped front frame 27. Whee]..s a-t 28 are rotatably moun-ted on stub shafts attached to the horizontal frame portions 25 so that the device comprises a wheeled seat support which is of a size and shape enabling it to be moved from the space be-tween the arms 10 as shown in Figure 1 of the drawings to a position forwardly of the front portions of the arms 10 as shown in Figures 2,3, and 4 of the drawings. The shape of the horizontal frame members 23, the vertical frame members 24 and the lower horizontal frame members 25 resembles a reversed C in configuration with the space between the open portion of the C-shape being sufficient to move over the crossbars 11 which extend be-tween the plates 12 attached to the arms 10.
By referring to ~igure 1 of the drawings, the wheeled seat support just described will be seen to be so positioned between the arms 10 and it will be seen that a pair of notched arms 29 are attached to the third flat frame Zl and depend on an angle therefrom and that the notches therein have engaged the forward one of the crossbars 11 and elevated the third flat frame 21 with respect t~-its pivotal relation to the upper horizontally 6~3 disposed frames 23. It will also be seen that a thin flat substantially square body member 30 is attached to the third flat frame 21 as is a vertically disposed rectangular body member 31. A second thin flat body member 32 is attached to the second flat frame 10 and a third thin flat body member 33 is attached to the first flat frame 17. The body members 30, 32 and 33 form a support for a single elongated cushion 34.
By referring to Figures 1,2 and 3 of the drawings, it will be seen that the elongated cushion 34 takes the form of a cushioned seat member when it is in a substantially horizontal position and inclined substantially vertical cushioned back member 34A and a depending angularly disposed section 34B when the convertible bed chair is in chair con-figuration. It will also be seen that the section 34B ofthe cushion 34 has a U-shaped reinforcing frame 35 affixed thereto which sildably engages the thin flat body member 33 as the cushion 34 and more particularly its sections 34A
and 34B change their length as they move from the positions illustrated in Figure 1 of the drawings to the positions illustrated in Figures 2,3, and 4 of the drawings. The ~ ~ -6-U-shpaed reinforcillg frame 35 suppor~;s the extending portion of tlle section 3~B of -the cushion 3~ when -the sarne moves outwardly beyond the thin flat body member 33 as illustrated by the directional arrows in Figures 2 and 6 of the drawings.
By referring now to Figure 6 of the drawings, it will be seen that the first flat frame 17 of the convertible bed chair supports the thin flat body member 33 on which the one-piece cushion 3~ and more par-ticularly its end portion 34B, rests illustrates the U-shaped reinforcing frame 34 in extended relation to the first flat frame 17 as hereinbefore described.
It will occur to those skilled in the art that the thin flat body member 33 also moves relative to the first fIat frame 17 as may be seen by comparing the relative position of the same to the other thin flat members 30 and 32 as seen in Figures 1,2, and 3 of the drawings and that provision is made for controlling the position of the thin flat body member 33 with respect to the first flat frame 17 and comprises an apertured fixture 36 on either side of the flat frame 17 through which an elongated guide rod 37 extends, the ends of the elongated guide rod being offset with respect to the remainder _7_ thereof and secured by fasteners 33 to the flat frame 17.
The construction is necessary to maintairt the respective thin flat body member 33 in desirable operative posi-tion on the first flat frame 17 when the conver-tible bed chair is moved from chair configuration to bed configuration.
In Figure 4 of the drawings, the utility of the U-shaped reinforcing frame 35 is emphasized ln that it is illustrated in extending relation to the first flat frame 17 as necessary to properly support the end portion 34B of the single cushion 34.
Figure 5 shows a substantially enlarged view of the hinges 18 which join the flat frames 19 and 17 respetively. The thin flat body members 32 and 33 are secured to the flat frames 19 and 17 respectively and the thin flat body member 30 is secured to the third flat frame 21. It will thus be seen that a very simple and inexpensive construction has been devised and disclosed herein which is capable of economic r,lanufacture when compared with the prior art devices as there are only the two arms 10, the transversely positioned crossbars 11 and the three flat frames with their thin flat body members necessary to form the entire operable structure which positions the cushions 34 and its sec-tions 34~ and 34~ in either the chair configuration as seen in Figure 1 o~ -the drawings and intermediate position as seen in Figure 2 o~ the drawings or a bed coni'iguration as seen in Figures 3,4 and 6 o~ the drawings.
~lthough but one embodiment of the present invention has been illustrated and described, it will be apparent to those skilled in the art t~at various changes and modiiications may be made therein without departing ~rom the spirit oi' the invention.
