ROCKABLE RECLINING CHAIR CONSTRUCTION Filed April 20, 1965 4 Sheets-Sheet 4 INVENTOR.

BRUNER T. BARKSDALE BY ATTOR United States Patent 3,295 885 ROCKABLE RECLINING ill-IAIR CONSTRUCTION Bruner T. Barksdale, 901 Lake Drive, Bainbridge, Ga. 31717 Filed Apr. 20, 1965, Ser. No. 449,396 13 Claims. (Cl. 297-34) The present invention relates in general to chairs, and more particularly to chairs of the variety generally known as reclining lounge chairs, which chairs may be adjusted to a variety of selected reclining positions. The present invention also relates to chairs of the type generally known as platform rockers, wherein the main seat portion of the chair is rockable upon a stationary frame.

The chair construction in accordance with the present invention provides a seat and a back portion secured to the seat and pivotable with respect thereto in a continuous manner so as to make possible a continuous adjustment of the reclining position of the chair after the fashion of reclining lounge chairs. In addition, the seat and back combination are pivotally mounted in a resilient manner on a support member secured to the stationary frame of the chair so that it is possible for the chair to rock in the manner of a platform rocker; and since the adjustable back portion of the chair is secured to and supported only by the seat portion of the chair, rocking may be effected for all positions of adjustment on the back portion. In combination with the rocking and reclining features of the chair construction in accordance with the invention there is provided an adjustable foot rest and an automatic actuating mechanism therefor including means for adjusting the elevation of the foot rest in the extended position. The result is a lounge-type chair which is completely adjustable from the vertical position of the back portion to a completely horizontal configuration with rocking thereof provided for all positions of the chair.

One very desirable feature of the instant invention resides in the back portion of the chair being pivotally connected to the seat thereof and spring biased so that the chair in the unoccupied position will normally assume an upright or vertical position of the back portion. A locking mechanism is provided between the back portion and the seat so that pressure against the back portion by the person occupying the chair will not produce a tilting thereof without release of the locking mechanism; however, the locking mechanism is so constructed that upon the release thereof the back may be titlted to any desired position by the normal pressure applied thereto in opposition to the spring bias, and because of the continuous adjusting feature of the locking mechanism, an infinite adjustment of the back portion is made possible. However, as soon as thepressure applied to the back portion is relieved, as when the person occupying the chair rises the locking mechanism will automatically release, allowing the spring bias to return the back portion to the upright or vertical position.

A further advantage resides in the fact that the chair .construction in accordance with the invention is also provided with a foot rest which extends from beneath the seat of the chair between the seat and the frame portion thereof, and is normally spring biased into its forward or extended position. A latch mechanism is provided for the foot rest mechanism so that the foot rest may be retracted and latched out of use against the normal spring bias whenever desired; however, due to the bias of the foot rest mechanism, the foot rest will extend automatically when the latch mechanism is released. This latch mechanism for the foot rest may be connected to the locking mechanism for the reclining back portion of the Patented Jan. 3, 1967 chair so that upon release of the back portion for adjustment to a reclining position the foot rest will automatically be released into the extended position. However, it is also within the purview of the invention to provide the locking mechanism for the foot rest independent from the locking mechanism for the back portion of the chair so that the foot rest may be retained in the retracted position whenever desired.

As a further advantage, the foot rest mechanism is also provided with a height adjusting means which makes possible an adjustment of the vertical position of the foot rest in the extended position. This adjusting means provides for several steps of adjustment so that the foot rest may be positioned in the vertical direction to provide various degrees of elevation thereof.

It is a primary object of the instant invention to provide a rockable reclining chair of extremely simple and sturdy construction characterized by economy of manufacture and versatility in use.

It is another obqect of the instant invention to provide a chair construction provided with a seat and back combination rockably supported on a fixed frame and adjustable with respect to one another between a vertical and a completely horizontal configuration of the back portion.

It is still another object of the instant invention to provide a rocking chair construction provided with a continuously adjustable reclining back portion and an automatically extending foot rest operable either in combination with the reclining back portion or independently thereof.

It is a further object of the instant invention to provide a chair construction capable of rocking upon a fixed frame portion and having a continuously adjustable back portion and an automatically extending foot rest capable of adjustment to a plurality of selected elevations in the extended position thereof.

It is still a further object of the instant invention to provide a chair construction having a reclining back portion and a locking mechanism therefore such that said back portion will lock in any desired position of inclination but will automatically return to the normal upright or vertical position when the chair becomes unoccupied.

By virtue of these and more specific features set forth with particularity in the following specification and claims the invention provides a rockable reclining chair construction which exhibits far superior characteristics to those heretofore attainable with a design of much less simplicity. This will be more fully understood from the embodiment of the invention illustrated by way of example in the accompanying drawings, wherein:

FIGURE 13 is a detailed view of the spring construction for the foot rest retracting mechanism illustrated in FIGURE 12.

Looking now to the drawings, wherein like reference numerals have been used to designate corresponding elements throughout the various views of the drawing, wherever possible, and more particularly to FIGURE 1, Wherein 10 and 11 represent a pair of frame members of any conventional construction serving as the base support for the chair and providing a basic outline which may accommodate a complete upholstering of the chair or may be utilized in its basic form to provide arms and support for the general chair construction. The frame members 10 and 11 are suitably secured to one another in a conventional manner, such as by means of a front face board 12 and a rear support board 13. The combination of frames 10 and 11 and the

support boards

12 and 13 constitute the stationary platfrom for the chair which is suitably reinforced in the conventional manner to provide a rigid structure capable of withstanding forces and weight encountered during normal use of such a device. No particular design for this platform construction is required by the invention so long as the structure strength provided thereby is sufiicient to support the remainder of the chair construction in use.

As seen both in FIGURES 1 and 2, a pivot rod 14 extends between the frame members 10 and 11 and is suitably secured thereto in any conventional manner, such as by brackets 15. The seat 16 of the chair is suitably secured to a pair of metal support members 18 which are in turn pivotally mounted on the support shaft 14 by means of a connecting linkage 19 secured to each of the support members 18. The back portion 17 of the chair is also pivotally mounted on extension 18a of support member 18 so that as a result of the pivotal connection between the support linkages 19 and the support rod 14, the entire seat construction is pivotable about the rod 14, supported by the platform or support frame of the chair.

In order to stabilize the chair in a neutral position, a pair of springs 20 is connected between each of the metal support members 18 and brackets 21 secured to the frame or platform of the chair. Since the seat of the chair is supported entirely upon the pivot rod 14, the support linkage 19 and the pivot rod 14 should be of sufiiciently sturdy construction to accommodate the forces necessary to support a heavy individual; however, by properly balancing the construction upon the pivot rod 14, the springs 20 may be provided of relatively light construction so that an extremely resilient rocking of the chair may be achieved. The seat member 16 is secured to the support member 18 in any suitable manner and the back portion 17 is pivotally secured to the extension 18a of the support member 18, as at 22.

The back portion 17 of the chair is biased in the normal upright or vertical position by a pair of spring members 23 (FIGURES 2 and 3) which extend between brackets 24 secured to the back portion 17, and a cross beam 25, secured to the support member 18. A guide rod 26 is pivotally fastened to the bracket 24 and extends through the center of the spring 23 passing through an aperture in the cross beam 25. A stop member 27 is fastened to the extreme end of the guide pin 26 on the opposite side of the cross beam from the spring 23 so that the upright rest position of the back portion 17 is determined by this stop. Pressure by the person occupying the chair against a back portion 17 will therefore pivot the back portion against the bias of springs 23 to a plurality of positions including the complete horizontal disposition of the back member in line with the seat member 16.

In order to retain the back member 17 in an upright or any intermediate position between the upright position and the horizontal position, a locking member generally designated 30in FIGURE 3 is provided. This locking member shown in detail in FIGURES 4 and 5 consists of a locking bar 31 pivotally mountedto the back portion 17 by a bracket 32. The free end of the blocking bar 31 passes through an aperture in a guide frame 33 which includes a generally U-shaped portion 34 accommodating one end of a latching member 35, the other end of which is secured to the guide bracket 33 by means of a spring 36. An aperture 35a in the locking plate 35 is a generally circular shape (FIGURE 5) dimensioned only slightly larger than the locking bar 31 so that pivoting of the plate 35 within the U-shaped portion 34 in response to spring 36 will cause a binding between the plate and the bar 31 locking the bar 31 in a fixed position. The bias of the spring 36 is further aided by normal pressure against the back portion 17 by the person occupying the chair which produces a downward movement of the locking bar 31 by further increasing the binding grip of the locking plate insuring a firm lock upon the bar. In order to release the bar, the locking plate 35 must be pivoted upward at the end attached to spring 36 until the plate is substantially transverse to the locking bar 31 allowing the bar to slip through the plate. This pivoting of the plate 35 is accomplished by a cam 37 mounted on a pivot lever 38 secured to the cross beam 25. The lever 38 is spring biased in the counter clockwise direction by spring 39, also attached to the cross beam 25 at flange 25a, so that the cam 37 is normally in the inoperative position. A control cable 40 is connected to the end of the lever 38 and serves to rotate the lever in the clockwise direction against the bias of spring 39 forcing the cam surface 37 against the locking plate 35 thereby pivoting the plate to a position transverse to the locking bar 31. The control cable 40 extends, for example, along the back of the chair and into one side frame member, such as frame member 11, where an actuating rod 41 is provided.

Due to the particular orientation of the locking bar 31 and the locking plate 35 any tendency for the back portion 17 to rise to the vertical position in response to bias by springs 23 will cause the locking bar 31 to move in a vertical direction pulling the plate 35 with it and forcing the plate into the substantially transverse position necessary for providing slippage between the bar 31 and the plate 35. As a result, if the person occupying the chair should rise, the back portion 17 will automatically return to the normal upright or vertical position.

In summary, it should be apparent that pressure against the back portion 17 in conjunction with actuation of the control lever 41 will allow the person occupying the chair to force the back portion 17 to a reclined position, and release of the actuating lever 41 will then produce and maintain a locking of the back portion 17 in the desired position as long as pressure is maintained thereon. However, as soon as the person occupying the chair rises, the back portion will assume its previous upright position.

As seen in FIGURES 1, 2, 6 and 7, the chair construction in accordance with the instant invention is also provided with a foot rest 50, which may be extended from the retracted position shown in FIGURE 6 to the extended position shown in FIGURE 2. The foot rest 50 is hinged to a pair of supports 51 which are in turn pivotally secured to a guide rod 52 beneath the seat 16. A pair of guide channels 53 are pivotally mounted on support shaft 54 mounted on the support members 18. The guide rod 52 connected to the foot rest 50 projects at either end into a respective guide channel 53 so that movement of the foot rest 50 from the retracted to the extended position is guided by the guide channel 53. The front end of each guide channel is provided with a support pin 55 which engages a respective pivot link 57 pivotally secured to supoprt rod 56, supported by the support member 18.

In order to extend and retract the foot rest 50 the guide rod 52 is reciprocated back and forth within the support channels 53 by a scissor linkage arrangement 60, seen most clearly in FIGURE 7. The arrangement 60 made up of scissor links 6% and 60b is secured at one end to the guide rod 52 by

links

520 and 52b and is pivotally mounted at the other end to the support rod 54 for the guide channels 53 by pivot levers 61a and 61b. The arrangement 60 is normally biased toward the extended position by connecting the free ends of levers 61a and 61b to a pair of brackets 63 through springs 62 such that the force of the springs 62 will pivot the members 61 forcing the linkage arrangement 60 outward pushing the guide rod 52 and thereby extending the foot rest 50. The foot rest 50 may be retracted against the force of springs 62 by applying a pressure at the end of the foot rest in the inward direction of the chair until the foot rest is urged into the position illustrated in FIG. 6. At this point, a latching mechanism illustrated in detail in FIGS. 9 and 10 serves to secure the foot rest in the retracted positon. A notch 70 is provided at one extreme end of one support member 51; which notch 70 engages in the retracted position of the foot rest with a locking lever 71 pivoted to the guide channel 53 at 72. A spring 73 urges the locking lever 71 in a clockwise direction, as seen in FIG. 9 to engage with the notch 70 locking the support 51 and preventing movement of the foot rest into the extended position in response to spring 62. A control cable 74 connected to the lever 71 serves as a guide rod for the spring 73 and also makes possible an actuation of the lever 71 in the counter-clockwise direction releasing the support 51 to allow the spring 62 to automatically extend the foot rest 50.

Since the links 57 which support the forward end of the pivotable guide channels 53 are also pivotable on the support rod 56, a cranking of the support rod 56 while the foot rest 50 is in the extended position will serve to adjust the elevation of the foot rest. In the alternative,

a pivoting of the foot rest about the upper edged faceboard 12 will produce a cranking of the support rod 56. Therefore, by controlling the cranking of support rod 56 the elevation of the foot rest may be adjusted. This control is accomplished by means of sector gear 80 connected to support rod 56, as seen in FIG. 11. A spring 81 is connected to the linkage 57 associated with each of the guide channels 53 and tends to bias the guide channel to the lower position raising the foot rest 50 to its highest elevation. A lower elevation of the foot rest is achieved by repressing the foot rest, which serves to rotate sector gear 80. The foot rest may then be retained at a given elevation by means of plunger stop member 83, which serves to secure the sector 80 in a given position. The plunger stop member 83 is actuated by means of a control 84 positioned on the upper frame portion of the support frame, within easy reach of the person occupying the chair.

It is seen from the structural arrangement provided by the described embodiment of the invention that since the entire chair mechanism including the feet, back portion, and'foot rest along with the associated operating mechanisms therefore are pivotally supported entirely upon the pivot rod 14, a rocking of the chair upon the platform or support frame will be possible regardless of the position of the back member 17 or the foot rest 50. In addition, the locking mechanism for the back portion 17 makes possible a continuous adjustment of this member and a locking thereof at any selected position from vertical to horizontal by releasing the latch mechanism and applying force against the back member 17 until the desired position is reached. At that time, the locking mechanism is released and a binding between the locking bar 31 and the locking plate 35 produced by the spring 36 and the force continuously applied on the back member 17 will prevent further adjustment of the seat. When the person occupying the seat rises, the force of springs 23 against the back member 17 will automatically release the locking member 30 allowing the back 17 to rise to its normal vertical position.

The foot rest being provided with a pair of biasing sprigs 62, an extension of the foot rest can be achieved by releasing the latch associated therewith either in conjunction with the release of the back locking mechanism or separately, if desired, and the foot rest 50 may also be adjusted with regard to the elevation thereof by a separate adjusting mechanism 84 within easy reach of the person occupying the chair.

A more simplified construction for the foot rest biasing mechanism is illustrated in FIGS. 12 and 13. In this arrangement instead of providing the levers 61 and spring members 62, a spring mechanism is provided at the point of cross-over of the linkages 60a and 60b. A detail of this mechanism is illustrated in FIG. 13. A spring keeper 91 is welded or otherwise suitably secured to the upper scissor link 60b and extends through the center of a coil spring 92 which is secured at one end to the lower scissor link 69a and at the other end to a tension adjustment plate 93. The tension adjustment plate 93 is secured to the spring keeper 91 by means of a fastener 94 so that the lower end of the coil spring 92 which is fastened to the tension adjustment plate 93 is effectively secured to the scissor link 60. This arrangement effectively provides a coil spring connection between the linkages 60b and 60a suitable to bias the scissor linkage in the open or extended position. The adjustment plate 93 may be rotated with respect to linkage 60b to increase or decrease the tension on the spring by loosening the fastener 94.

A retraction of the foot rest 50 will cause a closing of the scissor linkage 60b and 60a effecting a rotation of the coil spring 92 against the bias normally provided by this spring. This arrangement provides a much simpler and more economic construction than illustrated in FIG. 7, requiring a spring of less force than the springs 62 provided in the former construction.

While I have shown and described a specific embodiment in accordance with the instant invention, it is understood that the same is not limited thereto, but is susceptible of many changes and modifications within the spirit and scope thereof, and I therefore do not wish to be limited to the details shown and described herein, but intend to cover such changes and modifications as are encompassed by the scope of the appended claims.
