H. F. NILES CHAIR Filed June 12, 1939 Patented Feb. 3, 1942 UNITED STATES PATENT OFFICE CHAIR Harry F. Niles, El Cajon, C .f Application June 12, 1939, Serial No. 278,632
4 Claims.
ybottom portion of the chair body being formed upon a circle, with means for holding the back and seat together in different positions around the circular support therefor, whereby various inclined positions may be easily and quickly had with a minimum of adjustments and of effort.
My invention is particularly adaptable for railroad cars, busses, and also for homes and other places where an easy, adjustable chair is desired. i i Another object of my invention is to provide in an adjustable chair, an adjustable seat portion, whereby as the back and seat are togethermoved to a reclining position upon the circular support, the seat, instead of having its front edge raised up too high, can be let down so that the seat portion will be comfortable.
In order to describe my invention in detail, I have illustrated the same onthe accompanying sheet of drawings, which I will now describe. In the drawing:
Figure 1 is a side elevation ing my invention;
Figure 2 is an enlarged vertical sectional view, taken ony the line 2-2 of Fig. 1; and
` Figure 3 is a vertical sectional view taken on the line 3 3, of Fig. 2, showing one adjustment in light broken lines.
Referring now in detail 'to the drawing, my chair as here embodied for explanatory purposes, consists of a supporting base, preferably of sheet metal, and including the two side portions 4, 4, with the curved bed or bottom 5, of spherical form, that is: said bed or bottom 5 curves as a circle from the lower front upwardly to the top of the back of said, supporting base, and also from side to side, it will be noted that said bottom is slightly curved. The upper edges of said side members, are inturned, as at'l, to form inwardly of a chair embodyand moves in the inwardly opening guide and confining channels, and these serve to retain the chair proper in movable relationship to said supporting base.
The chair body is also formed of sheet metal with a back 1 extended from the lowermost front of the supporting base, when the chair is in normal upright position, upwardly around the back of said chair in a true circle to the top of the back portion of the chair, as clearly indicated in Fig. 3. This back member is also curvedtrans- 4an operating lever upturned flange versely, as will be understood from the sectional part thereof, as seen in Fig. 2, under the seat at 1'. Said back member has formed therein a series of indents or notches 8, 8, into which a holding dogV 9 can be turned proper in different positions of adjustment. Said holding dog 9 is mounted on a shaft I0, extended through bearings I I, I I, in the side members 4, 4, and is provided on its outer end with I2, whereby said holding dog can be moved to release or to lock the chair proper in an adjusted position in the supporting base. y
A spring I3; on the shaft III, operates to normally move said shaft and the holding dog to operative position to engage in any of said indents or notches 8, 8.
The back member of said seat or chair is provided with an angle or shelf-like member, as I4, crosswise thereof, and this constitutes a support for the lower end of the cushion back I5, which can be of any suitable cushioning material, and which is extended to the top and hooks over the top of the back member 1, as indicated at I6. Said back member 1 ofthe chair proper, terminates at its opposite sides in side portions, as I1, I1, with a formedbead portion I8, I8, extended slightly above the back of the base and which ts opening channels at 6, 6, Fig. 2.
The seat supporting member I9, is pivotally supported at its rearward end on a shaft 20, having its opposite ends in suitable bearings 2l, 2|, formed on the inner faces of the side members or portions I1, I1. The forward end of said supporting member I9, is supported by a hinged wing or front member 22, hinged at 23, and
adapted to be folded back, as indicated in the dotted line position, Fig. 3, to permit the seat proper to be lowered instead of projecting upwardly so far when the chair proper is moved to its lowermost position. A cushion 24 is shown mounted on the seat supporting member I9, which cushion is held in place at its lower front by an or portion I9'. Thev rear portion of said seat cushion extends under the lower end or toe portion I5' of the back cushion. The supporting wing member 22, when it is up in supporting position, as in full lines, Fig. 3, rests against the lower part of the ange or member I9' as shown.
It will be understood that the supporting base,-
for holding said chairk mobile, with such accuracy that the chair proper canbe moved from one position to the other around a true circle and can be lifted upwardly to remove the seat and back from the base. or, if there is no seat in front, could be moved downwardly and out of the supporting base, by simply turning the holding dog 9 downwardly to let the notches 8, 8 pass over it.
Thus I have provided a simple, practicalk and comfortable adjustable chair which is suitable for car, bus or room, and which can be adjusted from an upright position to a reclining position, with ease and security, and in which the seat proper can also be dropped to conform to a reclining position, as indicated in the light broken lines in Fig. 3, where the chair4 is moved to its low position, and the seat is also droppedl down to its low position.
I claim:
1. An adjustable chair including in combination a supporting base having side members and adapted to receive a chair thereon, a chair proper having a curved back and a seat slidably supported on said base between its side members, means forming a circular way extending from the lower front of said base to the upper rear thereofl and cooperating with means.v on said chair, whereby said chair can-bemoved in a circular movement from an upright position to an inclined position, said seat being hingediy supported between the side yportions of said back, means adjustably supporting the front of said seat whereby it can be lowered to a reclining position, and means for locking said chair in different positions along said circular path of movement. t
2. An adjustable chair including a base having side members and a bottom 'of curved form, said side members having circular guide means formed on their inner faces, a chair proper having a back member provided at its opposite sides with means to interiit with and slide along said circular guide means as said chair proper is moved in a circular path from an upright to a `rear to said back member,
reclining position along said guide means. means for locking said chair in difl'erent positions of adjustment in said circular guide means, a cushion upon the front of the back member of said chair, a seat with cushion h'ingedly connected at its the front of the seatsald means being adapted to let the front side of said seat down when the chair proper is moved to a reclining position.
3. An adjustable chair including a supporting base having sides with circular guide ways curving from the lower fronts upwardly and rearwardly, a chair proper having a curved back'and a seat movable as a unit and provided at its opposite sides with cooperating means for said circular guide ways, whereby said chair can be moved in a circular path from upright position to a reclining position, means interposed between said base and said chair proper for locking said chair in different positions of adjustment in said circular path of movement, the seat of said chair proper being hinged at its rear end to the back member and having a prop pivoted to the front end of the back member and extending upwardly and having its upper end bearing against the underside of the seat at its front end.
4. An adjustable chair including a base hav--v ing sides and a curved bottom extending from the floor upwardly and rearwardly between said sides, a chair back of curved form fitting the curved bottom of said base, interiitting guide means between the sides of said base and the sides of said chair back, to prevent lateral movement, interlocking means between said base and the back of said chair for locking said chair in different positions of adjustment, a seat pivotally connected to the chair back at its rear end, and foldable means under the forward end of said seat for supporting it and for lowering it when said chair is moved down to reclining position, and cushions mounted on said chair back andl said seat.
