Specification of Letters Patent.
latented Nov. 22, 1921.
Application filed February 19, 1921. Serial No. 446,423.
To all whom it may concern. I
Be it known that. I, HENRY A. SCHMIDT,
Long lsland City, in the. county of Queens and State of New York, have invented certain new and useful Improvements in Convertible Bed-Springs,.'ofwhich the following isa specification.
i This invention has relation to furniture, and has for an object to provide a bed spring which is so constructed as to be convertible from a fiat reclining support to an inclined support having seat, back and. leg rest portions so that the occupant may rest thereon in a semi-upright position.
Another object of the invention is to provide a convertiblebed spring of the character mentioned which consists of a main frame adapted to rest in an ordinary bed frame and having auxiliary spring'frames mounted thereon in pivoted relation and adapted, when in alinement to form a flat reclining surface, orwhen adjusted at relative angles to form a seat portion, back and leg rest.
In addition to the foregoing this invention comprehends improvements in the details of construction and arrangement ofparts to be hereinafter described and particularly set forth in the appended claims.
' In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference.
throughout the several views in which they appear,
Figure 1 is a view in perspective of a convertible bed spring constituted in accordance with my invention.
Fig. 2 is a view thereof in side elevation showing the parts in alinement to form a flat surface.
Fig. 3 is a similar view showing the parts positionedto form an inclined surface.
Fig. 4 is a view in side elevation of the auxiliary back rest.
Fig. 5 is a view in side elevation of one main frame bar.
Fig. 6 is a view in side elevation of the leg rest frame.
Fig. 7 is a view in side elevation of the seat frame. I
Fig. 8 is a view in perspective of a frame supporting bracket.
Fig. 9 is a view in side elevation of the actuating lever.
Fig. 10 is a view in side elevation of a link.
F 1g. 11 1s a view n side elevation of an lVith reference to the drawings, l0'indicates the longitudinal members of the main frame, formed preferably of angle iron, and which are connected at one end by means of the bar 11. Located at one end of the main frame is an auxiliaryframe or backrest frame consisting of the side bars 12 connected at one end by the bar 13 and having thelr opposite ends bent at right angles to form the offset portions 14. The latter are pivoted to the sidebars 10 intermediate the ends thereof. Another auxiliary frame termed the seat frame is provided consisting of the side members 15, one end of each of which is pivotally connected to the ends of the bars 12 at the point of flexure of the portions 14. A third auxiliary frame is provided termed the leg rest frame and consisting of the side bars 16 connected at one end by means of the bar 17 and having their opposite ends bent toform offset portions 18, the extremities of which are connected to the ends of the main frame bars 10, and the points of flexure connected to the terminals of the bars 15. These connections are made to the inner sides of the bars 10 and 15. To
reinforce these parts I provide links- 19" which pivotally connect the ends 'o f said bars 10 and 15 but contacfwith the outer faces thereof. An actuating lever 20 is provided which is pivoted at one end to the main frame member 10 on a point between the offsets 14c and '18 while its other end is pivoted to the frame member 15 by means of a bolt 21 which may be tight ened or loosened at will. The extremity of the lever is reduced to receive a removable handle 22. The auxiliary frames are all covered with spring supported reticulated material in the'conventional manner as indicated at 23 to form a supporting surface,
disposed in horizontal alinement as shown in Fig. 2, the offsets Hand 18 being'vertical.
The bars 12 will be supported upon brackets 28 which are mounted upon the main frame bars 10 and which are formed with bifurcated upper terminals to embrace the bars 12. To convert the device into a reclining chair the bolt 21 is loosened and the lever 20 moved forward This may be done by the the under side "of the seat frame to engage a complemental part mounted on the main frame so that the frames may be adjusted by rotation of the screw and thus be held positively in all positions. A socket member 30 is mountedon each side of the seat frame to receive the supporting standard 3lof a table 32, the latter being thus removable when desired.
From the foregoing it will be seen that I I have provideda novel apparatus which may be supported in a bed frame of any conventional form in place of the ordinary bed spring to permit invalids to elevate them selves to a reclining position during the day time and to restore the functions-of a bed for the night. This device may be .made on a small scale for embodiment in babies cribs.
Other uses and advantages will readily occur to those familiar with the art to which this invention appertains.
While have illustrated and described my invention with some degree of particularity I realize that in practice various alterations therein may be made; I therefore reserve the right and privilege of changing the form of the details of construction or'otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claims.
Having thus described my invention what I claim as new and desire to secure by United States Letters Patent is p 1. A convertible bed spring including a main frame, an auxiliary frame having angular ofiset terminals pivoted to the main frame, a second auxiliary frame having offset angular terminals also pivoted to the main frame, and a third auxiliary framepivotally supported upon and between the first 'and second frames. V
2. A convertible bed spring including a main frame, a back rest frame including side bars, right angular portions on said side bars pivoted'to the main frame, a leg rest frame including .side bars, right. angular portions on said side bars pivoted to the main frame, and a third set of side bars pivotally connecting the right angular portions of said frames.
3. A convertible bed spring including a main frame, back rest and leg rest spring frames pivoted thereto, a seat spring frame supported between said first mentioned frames, and a lever pivoted to the main frame and to the seat frame adapted upon oscillation to move said auxiliary frames relative to the main frame.
In testimony whereof I aflix my signature.
