This invention relates to improvements in chairs provided with a normally spring elerated seat, designed primarily to assist weak or convalescent persons to rise from the chair.
The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter* described and pointed out' in the claims. ,ln the drawings.-
Fig. l. is a sectional lview of my improved chair, showing theI seat in elevated position. Fig. 2 is a similar view showing the sent in its lowered position on the chair frame.
Fig. 3 is a sectional view'of a slightly difvferent form of the invention, showing the seat in elevated position. Y Fig. 4 is a similar view of themodiied form, but showing .the seat in lowered position.
The numeral 1 indicates an open chair frame, connected by the usual cross bars 2. The upper side -bars 3 of the frame are pro- .vided with ears 4'and 5, to afford a mounting f for the seat 6. A link 7 is pivoted to the forward ear 4, and the free end is pvoted to an ear 7 on the underside of the seat 6. Pivoted frame by abc-ll ycranklever 8 piroted to anl ear 9 on the chair frame, the long arm l2 of' the lever extending down into the chair frame and is attached to a spring A13, the rear end ol which is secured to t 1e frame.
' ingt In the operation of the construction shown in Figs. 1 and 2, the tension o iJ'the s` ring actrongh the bell crank lever an the link long arm of the bell crank lever lie under the seat, while the spring is put under tension so that 'i pon a person rising, the seat will be elevatet According to the construction shown in 11`igs. 3 and 4, the seat is rocked or tilted` when a person is being seated or rising from the chair.
What I claim as new and desire to secure by United States Letters Patent is: y
1. In a chair, the combination of a frame, a seat above the frame, a bell crank lever pivoted to the top of the frame, means for connecting the upper end of the bell crank lever to the bot-tom of the seat, the lower portion ot' the bell crank lever extending downwardly within the frame, and a spring attached at one end to the lower free end of the bell crank lever and at its opposite end to the rear of the fra-me, said spring being tensioned when the seat is closed on the frame to normally elevate the seat from the frame when the seat .is not in use.
2. In aehair, the combination of a frame, a seat above the frame, a link pivotally attached to an intermediate portion of the seat and the front of the frame, a bell crank lever" disposed at the rear of the link and having one end pivoted to the rear portion of the seat and at its intermediate portion thereof to the frame, and a spring attached at its forward end to the lower end of thebell crank' lever and at` its rear endto the rear of the trame, said spring being ti-nsioncil when the seat is closed on the vframe to normally elevato the sea-t from the frame when the seatis not 1n use.
