NT OFFICE This invention relates to furniture. This invention has utility when incorporated in a reclining chair.
Referring to the drawing: Fig.1 is a side view of a chair embodying the invention herein, said chair being in straight or upright position;
Fig. 2 is a view similar to Fig. 1 with the chair in tilted or reclining position;
Fig. 3 is a plan view through the frame of the chair of Fig. 1, approximately along the line III-III, Fig. 1, looking in the direction of the arrow;
Fig. 4 is a side view of the frame of Fig. 3, parts being broken away; and i Fig. 5 is a view on the line V--V, Fig. 4, looking in the direction of the arrow.
The invention herein comprises a chair which may be tilted from upright to reclining position by body movement of the occupant. It may also be again brought to straight or upright position solely by movement of the occupant. The shift- I ing of the chair is not only easily accomplished.
in .this manner but also remains in the predetermined desired position, allowing freedom of normal movement without throwing the chair out of the desired position.
The chair frame comprises front rail i, outer side rails 2 and rear rail 3. The side rails 2 are fixed with the front and rear rails l, 3. Upwardly extending from the forward portion of this frame are members 4, and upwardly extending from the rearward portion of the frame are members 5.
The members 4 provide supports for arms 6, while the members 5 provide the frame for back 1. This frame may be upholstered in any manner desired with the usual webbing, springs and outer covering 8 to produce the desired style or 1 motif in the piece.
Spaced inwardly from each outer rail 2 is a rail or frame member 9 fixed with the back rail 3 and with the front rail I. The forward ends of the rails 9 may be reinforced in their anchormg with the front rail 9 by means of blocks Ill.
Mounted by the rails 2, 8, are pins II as supports for carriers or rollers l2, there being a pair of such rollers on each side of the chair and spaced apart. The rails 2, 9, are each provided with downwardly extending portions I 3.
Support for the chair is provided by means of a pair of generally triangular shaped blocks M having their apices extending upwardly between the rollers l2; each block providing a pair of downwardly, oppositely extending divergent faces i 5, IS, in which, in the tilting of the chair, these faces provide tracks along which the rollers may shift. These downwardly diverging faces may be treated with a lubricant such as graphite to form a wear-resistant surface against normal wear 5 of the rollers thereupon and also providing a smooth surface for free movement of the rollers.
The angular extent of such faces may vary and, as herein shown, the rearwardly extending faces l6 have a sharper or greater downwardly l0 angular extent than the forward faces !5. The weight of the chair, as carried by this support, is so distributed that, by this difierent angularity, smooth action may be obtained; while in chairs having various distributions of weight, these faces 15 may be so disposed as to give a nicety of balance to the chair.
Mounted in faces iii are pins ll against which the forward roller l2 may abut in limiting the backward or reclining position of the chair, while the forward extent may be limited by legs 88 contacting the chair supporting surface l9. The portions I3 of the side rails extend downwardly to sheath the blocks It to a major extent in order to guard against side sway or side rocking of the supports. The chair may be moved from place to place without the blocks l4 dropping out i therefrom, in that pins 20 laterally extend from adjacent the apices of the blocks over cut-out portions 2| of outer side rails 2. The cut-out portions 2 I are in the region of movement of the rails 2 as to the pins, and as the chair is picked up, the pins 20 engage the upper face 22 of these cut-out regions and are lifted with the chair. In assembling the chair parts, these pins 20 may be placed in the blocks and as the covering 8 is placed over the frame, the pins 20 are thereby prevented from removal outwardly, while the side rails 9 prevent removal inwardly toward the under side of the chair.
The angular extent of the faces l5, I6, with their intersections or supporting member apices disposed between the rollers, may be gaged according to the size and weight of the chair so that an even distribution of weight is had on 45 a line approximately vertical through the supports or blocks. It takes but slight forward or. backward thrusting of the body of an occupant to. cause the chair to assume a reclining position or to be brought upward to an upright position, 50 and the extent of recline is sufficient for comfort .without strain. 7
What is claimed and it is desired to secure by Letters Patent is:
l. A chair comprising a base member, a seat 55 member, and a back for the seat member rising therefrom, one of said members being provided with iront and rear bearings at each side of the chair and nearer the back of said seat than the 5 front, said other member having at each side of said seat, oppositely inclined straight line bearing surfaces engaging said bearings, said rear hearing surfaces being of greater angle to the seat than the front surfaces.
10 2. A chair comprising a base member, a seat member providing a back, said seat member including a front rail and a back rail with a pair of spaced side rail members on each side thereof extending from one to the other thereby to prol5 vide a pair of guides, a roller mounted by and between each pair of side rails in the guides adjacent the central portion of the seat, and a roller mounted by and between each pair of side rails in the guides adjacent the rear of said seat, said 20 base comprising a pair of independent members each having bearing track means in engagement with said rollers including means comprising oppositely inclined front and rear bearing portions upwardly extending between said side rails to be thereby maintained in position by said guides be- 5 tween a pair of rollers on each side of said chair.
3. A chair comprising a base, a seat, a back for the seat rising therefrom, a first pair of rollers fixed to the sides of the seat just forward of the central portion of the seat, and a second pair of 10 rollers fixed to the sides of the seat adjacent the rear, said base having bearing track means at each of the chair sides in engagement with said rollers, said track means comprising oppositely inclined front and rear bearing portions, said rear bearing portions being inclined at a greater angle to the seat than said front bearing portions.
