3 Claims. (Cl. 155-106) This invention relates to chairs and, more particularly, to a pedestal supported reclining chair of the type used in barber shops and beauty parlors.

In accordance with the invention, such a chair is provided with a novel and simplified means for locking the back of the chair in any adjusted position, and with novel linkage means interconnecting the back and an extensible foot rest whereby the foot rest is swingably adjusted and projected or retracted automatically responsive to adjustment of the back of the chair.

For an understanding of the invention principles, reference is made to the following description of a typical embodiment thereof as illustrated in the accompanying drawing. In the drawing:

Figs. 1 and 2 are perspective views illustrating respectively, the upright and reclining positions of the chair;

Fig. 3 is an elevation view of the back of the chair, with the cover removed to show the adjusting mechamsm;

Fig. 4 is a sectional view on the line 44 of Fig. 3;

Fig. 5 is a sectional view on the line 5-5 of Fig. 3;

Figs. 6 and 7 are enlarged sectional views of the adjustment lock illustrating two different positions thereof;

Fig. 8 is a bottom plan view of the chair seat with parts removed to illustrate the linkage; and

Fig. 9 is a phantom elevation view of the chair with the linkage shown diagrammatically.

Referring to Figs. 1 and 2, the invention is illustrated as incorporated in an adjustable height reclining chair 10 of the type used in barber shops and beauty parlors. In this particular example, chair 10 is illustrated as mounted on a swivel base or support 11 of the type whose height is adjustable by hydraulic actuator means operated by a treadle 12. Chair 10 includes a generally U-shape metal frame 13 secured to the underside of seat 15 and shaped to form a foot rail 14, upright portions 16, and arms 17 to which arm rests 18 are secured.

A chair back 20 is pivotally mounted on portions '16 of frame 30, and a foot rest is hinged to the front edge of seat 15, by hinges 26, and has an extension 27 slidably mounted therein. A head rest 28 is adjustably mounted on back 20.

Referring to Figs. 3 through 7, back 20' includes a suitably padded quadrilateral frame 21 of Wood or metal to which a back cover is secured. Back 20 is pivotally supported on upright portions 16 of tubular frame 13 by means of a cross shaft 22 extending through the sides of frame 21 and having brackets 23 secured on its outer ends shaped to conformingly fit portions 16 to which brackets 23 are riveted or bolted. A crank 24 is secured to the midpoint of shaft 22, which latter is held against turning by brackets 23.

A pair of angle irons 31 extend in spaced relation vertically of frame 21 between the upper and lower members thereof. On the lower rail of frame 21, a pair of angle brackets 32 are mounted between angle irons 31, and shaft 22 extends through angle irons 31 and brackets 2,919,746 Patented Jan. 5, 196Q 32. Near the upper end of frame 21, a shaft 33 extends through the side rails of frame 21, through angle irons 31, and through an angle bracket 34 secured to the upper rail of frame 21 between angle irons 31. Shaft 33 has operating handles 30 secured to either end and is formed with a flattened eye 35 (Fig. 5) between one angle iron 31 and the nearer side rail of frame 21.

A bolt 36 extends through eye 35 and has a head 37 engaging the upper side of the eye. A sleeve 38 is slidable on bolt 36 and has a head 39 engaging the lower side of eye 35. The lower end of bolt 36 is threaded and extends through an aperture in the outer end of a locking bar 40. Locking bar 40 is adjustably positioned on bolt 36 by a nut 41 on the bolt, and a spring 42 embracing bolt 36 urges head 39 of sleeve 38 against eye 35 and bar 40 against nut 41.

Bar 40 extends with substantial clearance through an apertured boss 43 on a saddle plate 44 bolted to angle irons 31. The inner end of bar 40 is apertured to loosely embrace a rod 45 slidable through central apertured bosses 46 on plate 44, the plate having an aperture 47 between bosses 46. A coil spring 48 embraces rod 45 between bar 40 and the lower boss 46. A pin 51 connects the lower end of rod 45 to crank 24 and a pin 52 in the upper end of rod 45 limits relative downward movement of the rod.

The adjustment lock arrangement operates as follows. In the position shown in Figs. 3 and 6, the combined action of springs 42 and 48 biases locking bar counterclockwise and holds eye 35 flatly pressed between 37 and 39. In this position, bar 40 is cocked so that the corners of its inner aperture bite into rod 45, as shown in Fig. 6, and thus lock plate 44 and rod 45 against relative movement. If either handle 30 is rotated, eye 35 is turned to pull up head 37 and bolt 36. This swings bar 40 to the position of Fig. 7, so that rod 45 may move freely through the aperture in the inner end of bar 40. Back 20 may thus pivot about rod 22 relative to tubular frame 13, and is locked in adjusted position by releasing handle 30.

Adjustment of back 20 relative to frame 13 and seat 15 effects a corresponding adjustment of the position of foot rest 25 and the extent of projection of its extension 27. Referring to Figs. 8 and 9, seat 15 has a frame including side rails 53 and cross rails 54 of wood or metal, and tubular frame 13 is recurved along side rails 53. A pair of angle irons 55 extend between the side rails and support a plate 56 attached to pillar 11.

A bar 50 is slidably supported on the upper surface of plate 56 and carries a bracket 57 in which is secured a short rod 58. Rod 58 is connected by a universal joint 59 to an angular rod 60 whose outer end is pivotally connected to a bracket 61 secured to the bottom rail of chair back frame 21. Thus, when back 20 is adjusted about rod 22, bar 50 is moved correspondingly, along plate 56, by bent rod 60.

A pair of links 62 have their rear ends pivotally connected to the opposite ends of bar 50 and their forward ends pivotally connected to points intermediate the ends of a pair of links 63 whose rear ends are pivoted to a crossmember 64 adjacent rail 54 and secured in supports 66 at the forward corners of the seat frame. The outer ends of links 63 are pivotally connected to the inner ends of links 67 secured to hinges attached to extension 27.

As back 20 is tilted backward, bar 50 is moved forwardly to cause links 62 to swing links 63 outwardly to the full-line position of Fig. 8. Through links 67, foot rest 25 is swung out and up and extension 27 is projected outwardly. A reverse movement takes place when back 20 is swung toward the upright position of Fig. 1, the linkage then assuming the position shown in broken lines in Fig. 8.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the invention principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
