FOLDABLE SEAT Filed April 21, 1948 1N VEN TOR.
A TTORNEY Patented May 30, 1950 UNITED STATES PATENT OFFICE FOLDABLE SEAT Roy E. Burch, Midland, Mich.
Application April 21, 1948, Serial No. 22,365
This invention relates to a foldable seat structure adapted to be associated with backless benches or plank bleachers such as used in football stadiums, grandstands, and similar buildings.
Gne of the prime objects of the invention is to design a very simple, practical, and relatively inexpensive, lightweight, foldable seat structure which can be readily folded into a compact bundle for easy carrying and/or storage, and
which is provided with flexible canvas or cloth seat :and backrest sections to prevent the users clothing from Contact with the surface of the stadium bench or plank, and provide a comfortable backrest, enabling the owner to relax in comfort and enjoy the spectacle or game being played.
A further object is to provide an adjustable seat which can be readily adjusted to suit benches or planks of varying widths and/or size.
Still a further object is to design a lightweight seat which can be readily manufactured and assembled, and which is foldable into a compact bundle for convenient and easy transportation from place to place.
With the above and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claim, it being understood that changes may be made in the form, size, proportion, and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the invention.
In the drawing:
Fig. l is a perspective, elevational View of my foldable sea-t, showing it in place on a, plank such as customarily serves as a stadium seat.
Fig. 2 is a side-elevational view thereof.
Fig. 3 is a fragmentary, side-elevational view illustrating the adjustable leg.
Fig. 4 is a view showing the seat folded for carrying.
Referring now more specically to the drawing in which I have shown the preferred embodiment of my invention. The numeral 5 indicates the plank or raised bench such as found in stadiums in general, and this is usually formed of a single piece of material of standard width, or it may comprise spaced-apart sections of the same general width.
My foldable seat comprises a back frame 6, bowed as clearly shown in Fig. 1 of the drawing, and spaced apart legs 'I and 8 are pivotally connected to the end sections s of this bowed back at a point spaced from the lower ends thereof by means of pins or bolts Ill, the lower end sections 9 of the back frame bearing against the rear edge of the plank, and as clearly shown in Fig. 2.
These legs I and 8 are adjustable as to length, the one end being threaded as at II, and one end I2 of a hook member I3 has threaded engagement therewith, the opposite end I4 being turned inwardly to form substantially U-shaped hooks which fit over the front edge of the plank 5, and lit will be obvious that these legs can be adjusted as desired by threading the member I3 into or out of the legs, and then tightening the locking nut I5 to hold it in set position.
The upper section of the bowed back frame 6 is bent rearwardly as shown at I6 and a cloth or canvas I'I spans said frame and is secured thereto in any approved manner to form a comfortable and. flexible backrest, and looped tabs I3 are provided on this cloth backrest and for a purpose to be presently described.
A similar cloth or canvas strip I9 spans the legs 7 and 8, and forms the seat of the structure, and these members I'I and I9 are readily washable so that a clean, neat appearing structure can be had.
In practice, the structure is set up as clearly shown in Figs. 1 and 2 of the drawing. The hook-shaped end sections I3 of the legs are adiusted to span the support 5 and the structure is then ready for use, providing a comfortable and clean chair which can be easily and quickly set up and/or folded for carrying purposes or folded for storage when not in use.
From the foregoing description, it will be obvious that I have perfected a very simple, practical and inexpensive foldable seat structure, which is convenient in use, and whichr can be folded into a very compact bundle for carrying or storage.
What I claim is:
A foldable seat structure adapted to be mounted on a backless support, and comprising a bowed backframe, a pair of internally threaded adjustable legs pivotally connected to the lower end sections of the bowed back frame at a point spaced from the free ends thereof, longitudinally adjustable U-shaped end hooks forming part of said legs, one end of each U-shaped hook being threaded for engagement with one of said legs, locking means for securing the hooks in adjusted position, a flexible backrest spanning said back frame, and tabs on said flexible backrest and accommodating the free ends of the U-shaped members for securing the seat in its folded position.
