Description
July 28, 1942. A. KRAKAUER FOLDING BED QHAIR Filed June28, 1939 INVENTOR Abraham lfmkauer Patented July 28, 1942 I UNITED STATES ATENT OFFICE FOLDING BED CHAIR Application June 28, 1939, Serial No. 281,572
5 Claims.
This invention relates to folding bed-chairs and the like articles of furniture and particularly to the metallic folding frames thereof whereby the frames may be extended to form a bed and collapsed to form a chair, couch, or the like article.
My invention contemplates the provision of a simple and efiicient folding structure adequately supported in both the folded and extended positions thereof and adapted to be easily and conveniently manipulated by unskilled persons for converting a chair or couch into a bed and vice versa.
The various objects of the invention will be clear from the description which follows and from the drawing, in which,
Fig. 1 is a vertical section of a bed-chair to which my invention has been applied, showing the removable cushions or mattress in dash-dot lines and showing the bed-chair in its chairforming position.
Fig. 2 is a perspective view of the bed-chair as it appears in its bed-forming position but with the cushions removed.
Fig. 3 is a similar view of the same in the chairforming position thereof.
Fig. 4 is a fragmentary vertical section taken on the line 4-4 of Fig. 2, and showing particularly the means for automatically extending and collapsing the folding legs of the frame.
Fig. 5 is a top plan view of the same.
In the practical embodiment of the invention which I have shown by way of example, the chair or couch frame I may be of the usual wood construction and of the desired length to accommodate one or more persons. In what follows, the article of furniture to which the invention is applied will be termed a bed-chair though it will be understood that the invention is equally applicable to a couch long enough to seat two or more persons, in which case the various frames are made long enough for that purpose. The frame I0 is designed to pivotally support the back-forming frame II and the U-shaped frame sections I2 and I3 which are foldable or collapsible into the chair frame into a position to constitute a seat. The back frame II is composed of angle iron members, the frame being provided with the usual combined wire and spring structure I4 constituting a spring support for a cushion or mattress. For pivotally securing the back frame in place so that it may be swung from its back-forming position to its bed-forming position, the back frame is pivoted to the side rails I6 and I! of the chair frame as by means of the pivots I in the form of screws, bolts or the like, each entering the inner surface of one of the side rails IE or IT. A pair of fixed brackets as I8, I9 are secured to the chair rails I6 and I1, respectively, the horizontally extending flanges of said brackets serving to engage the lowermost part of the back below the pivots I5 and to prevent tilting of the back beyond a predetermined position as shown, for example, in Figs. 1 and 3.
The remaining sections I2 and I3 of the bed frame also constitute the seat for the chair (Figs. 1 and 3), and when extended, lie in the same plane as the downfolded back II to form a continuous bed frame as shown in Fig. 2. Said sections are each also preferably made of angle iron members and in the form of U-shaped frames, open at the adjacent ends thereof. The rear section I3 comprises the cross bar and the side rails 2! and 22. Secured in spaced relation and to the face 23 of the bar 20 are the brackets 24 and 25, each having a horizontal flange extending underneath the cross bar 25 of the back II so that when the back is swung to its horizontal position and the section I3 is in its extended position, said cross bar 26 rests upon the then horizontal flanges of said brackets 24, 25 to support the front end of said back.
Secured to each of the side rails 2| and 22 of the section I3 is a preferably Z-shaped bracket 21 having its inner flange secured to the side rail and having its outer flange pivotally secured, as by the pivot 28, to the inner surface of the side rail or wall ll of the chair frame. It will therefore be seen that when the back II is raised into its back-forming position, the section I3 may be swung from its bed-forming position about its pivots 28 through an angle of 180 and into the collapsed or seat-forming position shown in Figs. 1 and 3.
The section I2 is pivoted at its open rear end to the open front end of the section I3 as by means of the pivots 29 which also serve to pivot the folding legs 30 to said sections. Said legs are also made preferably of angle iron and are adapted to have the sections I2 and I3 folded on opposite sides thereof and in opposite directions so that the legs when folded, lie between said sections. This is accomplished by means of a pair of diagonal braces 3| and 32 for each leg, the braces of each pair being pivoted preferably by a common pivot at their lower ends to one of the legs. The upper end of the brace 3| carries the pin 33 slidably mounted in the longitudinal slot to of the side rail 22 of the section I3. Similarly, the upper end of the brace 32 is provided with a pin 35 sliding in the longitudinal slot 36 of the side rail of the section l2. Said legs are preferably interconnected and cross-braced to each other as by means of the diagonal braces 31 and 38, each of which is connected at one end to the lower part of one leg and at its opposite end to the upper part of the other corresponding folding leg (Fig. 2).
It will thus be seen that when the section I3 is swung from its bed-forming position about its pivots 28 in a clockwise direction, as viewed in Fig. 2, the section I 2 is simultaneously swung about the pivots 29 in a counterclockwise direction, so that while the section .13 is reversed in its folded position from that assumed in its extended position, the section i2 is moved rearwardly but remains in the same relative rightside-up position when folded that it assumes when extended, and while it is withdrawn inside of the chair frame If as is shown in Fig. 1.
To support the section [2 so that it serves as a seat when in its folded position and is adequately supported in its extended position to serve as part of a bed, a pair of fixed legs as 39 are secured to the respective side rails of the section 12, being braced, if desired, by means of a suitable fixed brace Ml. Each of the sections I2 and I3 is provided with a suitable bed spring structure M similar, if desired, to the structure [4 in the back.
It will be understood that when the sections I2 and [3 are folded both with respect to each other and with respect to the chair frame, the upper ends of the braces 3| and 32 move outwardly along the respective slots 34 and 36 so that the side rails of said sections assume a position substantially parallel to said legs 3!), the upright flange of the side rail 22 moving into the leg while the upright flange of the corresponding side rail of the section [2 moves outside of the adjacent flange of the leg 30 so that the parts nest to the required extent to form a compact folded structure.
It will also be seen that in the folded position of the parts, shown in Figs. 1 and 3, the fixed legs 39 serve to support the uppermost section [2 whereby said section serves adequately as a seat and is adequately supported by the fixed legs and the fixed pivots 29 against the weight of a user of the bed-chair when said bed-chair is used as a chair. Similarly, the section I3 is supported by its pivots 23 at its front end when folded, and its rear end rests on the brackets I 8, I9 which are properly positioned for that purpose.
In the extended positions of the parts, the back II is supported at its rear end by the pivots l5, and at its front end by the brackets 24, 25 extending from the frame section [3, Said frame section I 3, when extended, is supported by the legs 30 at its front end and by the pivoted brackets 21 at its rear end. The section [2 when extended is supported by the legs 39 at its rear end and by the fixed legs 39 at its front end.
The fixed bars 42 extending between .the pivots 28 and I and secured to the respective side rails l6 and l! of the chair frame serve to brace and fix said pivots and to prevent any change in the relative distance therebetween, thereby to permit easy folding and unfolding of the parts without interference or jamming.
It will be seen that I have provided a folding frame structure simple and easy to operate, economical to produce, and efficient in its operation and therefore well designed to effect the purposes for which it is intended.
While I have shown and described certain specific embodiments of my invention, I do not wish to be understood as limiting myself thereto, but intend to claim the invention as broadly as may be permitted by the state of the prior art and the scope of the appended claims.
I claim:
1.
