10 Claims. (Cl. 155-106) This invention relates to reclining furniture. It is particularly directed to a chair comprising a seat portion, a back rest portion, and a leg rest, and provided with means for swinging the leg rest forwardly and upwardly as the seat and back rest portions are moved to reclining position.

This invention is a continuation-in-part of the invention disclosed in the applicants patent application, Serial No. 494,886, filed March 17, 1955, now US. Patent No. 2,838,093, issued June 10, 1958, and entitled Reclining Furniture.

The principal object of the present invention is to provide an article of furniture of the character described in which simplified mechanism is provided for actuating the leg rest when the seat and back rest are moved to the reclining position.

Another object of this invention is to provide a strong, rugged and durable chair or sofa of the character described, which shall be relatively inexpensive to manufacture, easy to manipulate, comfortable in use, easy to assemble, and which shall yet be practical and eflicient to a high degree.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

This invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the construction hereinafter described, and of which the scope of the invention will be indicated in the appended claims.

In the drawings forming a part of this specification and accompanying the same,

Fig. 1 is a vertical cross-sectional view extending from front to rear of an article of furniture embodying the invention, showing one side of the mechanism which controls the movement of the seat and leg rest, and showing said article in upright position;

Fig. 2 is a top plan view of a structure shown in Fig. 1;

Fig. 3 is a cross-sectional view taken on line 3-3 of Fig. 1;

Fig. 4 is a cross-sectional view taken on line 44 of Fig. l; and

Fig. 5 is a view similar to Fig. 1 and showing a modified form of the invention.

Referring now in detail to the drawings, wherein like reference numerals denote corresponding parts throughout the several views, designates an article of furniture such as a chair or sofa, embodying the invention. The same comprises generally a supporting frame 11, a seat 12 pivoted thereto in the manner hereinafter to be described, a back rest 13, and a leg rest 14.

The supporting frame 11 comprises a pair of side walls 15, interconnected by a transverse bracing slat 16. Attached to the front of the side walls 15 is a front frame portion 17 supported on front legs 18. The rear ends of the side walls 15 are interconnected by a rear transverse bracing slat 20 and supported on rear legs 21. The frame may be provided with arm rests (not shown) if desired. The mechanism which interconnects the leg rest 14 with States atent O 2,884,990 Patented May 5, 1959 the seat is the same on opposite sides of the chair-and both are located at the inside of the side walls of the chair. For this reason, the mechanism on only one side will be described.

The back rest 13 is fixed to the rear end of the seat 12, which may be upholstered in any suitable manner as at 25. Said back rest may also be upholstered as at 26 in any suitable manner.

Attached to the inner surface of side wall 15 is a bracket 27 having a web portion 28 fixed as by screws 29 to said wall 15. Extending forwardly from the web 27 are parallel walls 30. Extending rearwardly from one wall 30 is a foot 31, and extending from the other wall 30 is a foot 32. Pivoted to the foot 31 as on pivot pin 33, is a triangular plate 34.

The pivot pin 33 may have a head 35 at one end, and a flanged portion 36 at its other end (see Fig. 4). On the pivot pin 33 and between foot 31 and plate 34 is a nylon disc 37, and between wall 34 and the flanged portion 36 is a second nylon disc 38. These nylon discs serve as friction members and as brakes for slowing the movement of the chair to and from reclining position.

The upper end of the triangular plate 34 is fixed as by screws 39 to the frame 40 of seat 12.

Pivoted to foot 32 of bracket web 27 as at 41, is a lever 42. The lever 42 has an upwardly extending arm 43, the upper end of which is connected as by link 44 to a pin 45 on the triangular plate 34. Lever 42 has an arm 46 having portions 47 and 48 forming an obtuse angle. On portion 48 of arm 46 of lever 42 is a rivet or pin 49. At the under side of the front end of the seat 12 is a block 50. Pivoted to the block 50 as by pivoted pin 51, is one end of a link 52. Said link 52 is formed with an oversized hole or small slot 53 (Fig. 3), receiving pin 49.

Pivoted to wall or foot 32 of bracket 27 and disposed forwardly of the pivot pin 41 is one end of a lever 54. Pivoted to the outer end of said arm 48, as at 55, is a lever 56. The

levers

54 and 56 are interpivoted mediately of the ends thereof, as by pivot pin 57, and cross each other. Pivoted to the outer end of lever 56, as at 57, is the leg rest 14. The leg rest 14 is also connected by a link 59 to the lower end of the lever 54. As the seat is moved from upright to reclining position, the seatv Attached to the arm 47 of lever 42 is one end of :1V chain 60. The other end of the chain 60 is connected to one end of a coil tension spring 61. The other end of the coil tension spring is attached, as at 62, to the triangular plate 34. When the chair is in upright posi-x tion, the spring 61 is slack and so is the chain 60. However, when the chair is moved to reclining position, the spring 61 will become tensioned to cushion the end of the reclining movement, and when a person desires to move from reclining to upright position, the tension 0f the spring 61 will aid the initial movement. The distance between the rivets 51 and 49 remains substantially. constant as the chair moves from upright to reclining po-.

sition. However, a slight variation in the distance is permitted by the oversized rivet opening or slot 53. When the seat is in upright position, the link 52 rests on the rivet 49 and when the chair is in reclining position, the link 52 pulls up on the rivet 49.

The modified chair construction shown in Fig. Sldiffers essentially from the embodiment shown in Figs. 1-4

and described above, in that the link 52 forming part of the mechanism in the first embodiment, is omitted. Also, the lever 56 in the embodiment illustrated in Fig. has a centrally fixed forwardly-extending plate 56a, the forward end of which abuts the underside of the leg rest 14 when the chair is in erect position, thereby serving as a stop when the seat is moved to said erect position, The triangular plate 34a, corresponding to the plate 34 in Fig. l, is provided with a plurality of openings 34b by means of which it can be adjustably secured with respect to the bottom of the seat 12. The lever 42a in Fig. 5 corresponds to the lever 42 in Fig. 1, the only difference being that the lever 42a is of curved rather than angular shape. The chain 60 and spring 61 shown in Fig. 1, are omitted from the embodiment in Fig. 5. The operation of this modified embodiment illustrated in Fig. 5 is the same as that in the first embodiment illustrated in Figs. 1 4, described above. I

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is Well adapted to meet the conditions of practical use.

As other possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings, is to be interpreted as illustrative and not in a limiting sense.
