The present invention relates generally to seating units, and relates more particularly to reclining seating units.
Conventionally, a recliner chair will move from an upright position, in which the backrest is generally upright, to one or more reclined positions, in which the backrest pivots to be less upright. The movement of the seating unit between the upright and reclined positions is typically controlled by a pair of synchronized reclining mechanisms that are attached to the seat, backrest and base of the chair. Many recliners will have an extendable footrest that provides support for the occupant's feet in the reclined position.
One particularly popular recliner is the “three-way” recliner, which has two reclined positions: a “TV position”, in which the footrest or ottoman of the chair is projected forwardly from the chair while the backrest remains substantially upright; and a “fully reclined position”, in which the backrest is less upright (i.e., it has been reclined to a shallower angle relative to the floor. In a “three-way” recliner, the backrest pivots relative to the seat as the chair takes its fully reclined position; this differs from a “two-way” recliner, in which the backrest and seat are rigidly fixed and do not pivot relative to one another as the chair moves to the fully reclined position. Many three-way recliners are constructed such that the backrest and footrest are coupled to one another, such that reclining of the backrest cannot occur unless the footrest is already extended (i.e., the chair is in the TV position). See, e.g., U.S. Pat. No. 4,915,444 to Rogers, Jr. and U.S. Pat. No. 6,540,291 to Hoffman, which illustrate chairs of rather contemporary style with three-way reclining capability.
Nevertheless, some reclining mechanisms are not well-suited for certain chair styles. As an example, some reclining chairs have “T-shaped” cushions (often termed “T-cushions”) that have laterally projecting wings positioned in front of the chair's arms. If the recliner chair is configured such that the seat moves rearwardly relative to the arms when moving to the TV or reclined positions, the wings on the T-cushion can catch on the front of the arms prevent the cushion from moving with the seat, such that the cushion is improperly positioned relative to the backrest. The T-cushion may also be mispositioned if the lower end of the backrest separates significantly from the rear end of the seat.
As another example of a chair that presents some difficulty for reclining mechanisms, some chairs have a “high leg” style in which the arms of the chair are raised several inches off of the underlying surface (typically between about 4 and 9 inches). It is ordinarily undesirable for portions of a reclining mechanism to be visible in the space below the chair when the chair is in the upright position, so the designers are faced with providing a reclining mechanism that folds into a relatively small package.
It would be desirable to provide chairs that address some of these needs.
As a first aspect, embodiments of the invention are directed to an elevated mount chair comprising: a base; a pair of arms; a seat positioned above the base between the arms; a backrest; a first ottoman; a reclining mechanism attached to the base, the seat and the backrest; and a footrest mechanism attached to the seat and the first ottoman, the footrest mechanism being coupled to the reclining mechanism. The seat includes a T-cushion positioned above a seat frame, the T-cushion having lateral wings that are positioned forward of the arms. The reclining and footrest mechanisms comprise a plurality of pivotally interconnected links configured to move the chair between (a) an upright position, in which the backrest is disposed at a first generally upright backrest angle, the seat is disposed at a first generally horizontal seat angle, and the first ottoman is retracted below a forward portion of the seat, (b) a TV position, in which the backrest substantially maintains the first backrest angle, the seat is disposed at a second seat angle that is steeper than the first seat angle; and the first ottoman is extended in front of the seat and is generally horizontally disposed, and (c) a fully reclined position, in which the backrest is disposed at a second backrest angle that is shallower than the first backrest angle, and the first ottoman remains extended in front of the seat. In moving between the upright, TV and fully reclined positions, a front portion of the seat experiences substantially no forward or rearward movement relative to the arms.
As a second aspect, embodiments of the invention are directed to an elevated mount chair comprising: a base; a pair of arms; a seat positioned above the base between the arms; a backrest; a first ottoman; a reclining mechanism attached to the base, the seat and the backrest; and a footrest mechanism attached to the seat and the first ottoman, the footrest mechanism being coupled to the reclining mechanism. The seat includes a T-cushion positioned above a seat frame, the T-cushion having lateral wings that are positioned forward of the arms. The reclining and footrest mechanisms comprise a plurality of pivotally interconnected links configured to move the chair between (a) an upright position, in which the backrest is disposed at a first generally upright backrest angle, the seat is disposed at a first generally horizontal seat angle, and the first ottoman is retracted below a forward portion of the seat, (b) a TV position, in which the backrest substantially maintains the first backrest angle, the seat is disposed at a second seat angle that is steeper than the first seat angle; and the first ottoman is extended in front of the seat and is generally horizontally disposed, and (c) a fully reclined position, in which the backrest is disposed at a second backrest angle that is shallower than the first backrest angle, and the first ottoman remains extended in front of the seat. In the upright position, a lowermost portion of the reclining and footrest mechanisms is between about 5 and 7 inches from an uppermost portion of the seat frame.
The present invention now is described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Like numbers refer to like elements throughout. In the figures, the thickness of certain lines, layers, components, elements or features may be exaggerated for clarity. Broken lines illustrate optional features or operations unless specified otherwise.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. As used herein, phrases such as “between X and Y” and “between about X and Y” should be interpreted to include X and Y. As used herein, phrases such as “between about X and Y” mean “between about X and about Y.” As used herein, phrases such as “from about X to Y” mean “from about X to about Y.”
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and relevant art and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein. Well-known functions or constructions may not be described in detail for brevity and/or clarity.
It will be understood that when an element is referred to as being “on”, “attached” to, “connected” to, “coupled” with, “contacting”, etc., another element, it can be directly on, attached to, connected to, coupled with or contacting the other element or intervening elements may also be present. In contrast, when an element is referred to as being, for example, “directly on”, “directly attached” to, “directly connected” to, “directly coupled” with or “directly contacting” another element, there are no intervening elements present. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed “adjacent” another feature may have portions that overlap or underlie the adjacent feature.
The seating units illustrated and described herein comprise a plurality of pivotally interconnected links. Those skilled in this art will appreciate that the pivots between links can take a variety of configurations, such as pivot pins, rivets, bolt and nut combinations, and the like, any of which would be suitable for use with the present invention. Also, the shapes of the links may vary as desired, as may the locations of certain of the pivots. Moreover, in some instances combinations of pivot points may be replaced by equivalent structures, such as “slider-crank” configurations, like those described in B. Paul. Kinematics and Dynamics of Planar Machinery 4-21 (1979).
Referring now to the figures, a reclining chair, designated broadly at 20, is shown in
Referring to
The seat 110 includes a generally rectangular seat frame 112 that underlies a cushion (not shown). A serpentine seat adapter 114 is mounted to each side of the seat frame 112. A T-cushion 115 with wings 115a rests on and above the seat frame 112 (see
The reclining mechanisms 30 are mirror images of each other about a vertical plane P that bisects the chair 20 between the arms 28 (see
The reclining mechanism 30 is mounted to the base 22 via a mounting bracket 36 that is fixed to the mounting rail 34. A coupling link 38 is attached to the forward end of the mounting bracket 36 at a pivot 40. A three-fingered transition plate 42 is attached at its forward end to the rear end of the coupling link 38 at a pivot 44, and at a central portion to the seat adapter at a pivot 45. A short control link 46 extends upwardly from a pivot 48 with the mounting bracket 36. A tripartite transition link 50 is attached at its rear end to the rearmost finger of the transition plate 42 at a pivot 51 and at a central location to the upper end of the control link 46 at a pivot 52.
A short drawing link 54 is attached at its forward end to the lower portion of the transition plate 42 at a pivot 56. At its opposite end, the drawing link 54 is attached to the lower end of a backpost 58 at a pivot 60. The opposite upper end of the backpost 58 is fixed to the backrest 130. A central portion of the backpost 58 is attached to the seat adapter 114 at a pivot 61. A slide link 62 is attached at its upper end to the seat adapter 114 at the pivot 45; at its lower end, the slide link 62 includes a slot 62a that receives a pin 66a extending from a connecting link 66. The connecting link 66 is attached to the forward end of the transition link 50 at a pivot 68 and extends forwardly therefrom to attach to the footrest mechanism 70 as described below.
The footrest mechanism 70 includes an upper ottoman swing link 72 that is attached to the forward end of the seat adapter 114 at a pivot 74, and a lower ottoman swing link 76 that is attached to seat adapter 114 at a pivot 78. The lower ottoman swing link is also attached to the forward end of the connecting link 66 at a pivot 77. An upper ottoman extension link 80 is attached at its rear end to the lower ottoman swing link 76 at a pivot 82, and is also attached to the upper ottoman swing link 72 at a pivot 83. A lower ottoman extension link 84 is attached to the forward end of the upper ottoman swing link 72 at a pivot 86. Each of the upper and lower ottoman extension links 80, 84 is attached to a main ottoman bracket 96 at pivots 97, 98 respectively. The main ottoman bracket 96 supports the main ottoman 140b.
An inner ottoman bracket 88 is attached to the lower ottoman extension link 84 at a pivot 90 and extends upwardly and slightly rearwardly therefrom. A brace 92 is attached to the inner ottoman bracket 88 at a pivot 93 and to the upper ottoman extension link 80 at a pivot 94. The inner ottoman bracket 88 supports the inner ottoman 140a from underneath.
An outer ottoman bracket 100 is attached to the main ottoman bracket 96 at a pivot 103 and extends forwardly therefrom. A control link 104 extends from a pivot 105 with the forward end of the lower ottoman extension link 84 to a pivot 106 with the outer ottoman bracket 100. The outer ottoman bracket 100 supports the outer ottoman 140c.
The footrest mechanism 70 includes an L-shaped handle 116 that is used to extend the ottomans 140a, 140b, 140c. The handle 116 includes an extension 118 that extends rearwardly, then downwardly, from the shorter “leg” of the handle 116, and also extends slightly forwardly of the shorter “leg.” The forward end of the extension 118 is attached to a drive link 120 at a pivot 122. At its opposite end, the drive link 120 is attached to the upper ottoman swing link 72 at a pivot 124. The rear end of the extension 118 is attached to the seat adapter 114 at a pivot 126.
Referring now to
Also, in the upright position, the slide link 62 and the transition link 50 are oriented with their forward ends (which are attached to the transition plate 42) above their lower ends, with the pin 66a of the connecting link 66 located at the lower end of the slot 62a. As a result, the pitch angle β of the seat 110 is relatively shallow (about 3 to 9 degrees) compared to the underlying surface.
It is also notable that, in this position, the forward portion of the seat frame 112 extends slightly in front of the arms 28. As such, the T-cushion 115 can rest on the seat frame 112 with the “ears” of the T-cushion 115 positioned in front of the arms 28.
It is also notable that, in the upright position, the difference in elevation between the lowermost portion of the reclining and footrest mechanisms 30, 70 (represented by the connecting link 66 and the transition link 50) and the uppermost portion of the seat frame 112 is between about 5 and 7 inches. Because the mechanisms 30, 70 fold into such a small vertical package, the mechanisms 30, 70 are suitable for use with a high leg chair like that shown herein.
To move the chair 20 from the upright position of
Also, the forward movement of the lower ottoman swing link 76 draws the connecting link 66 forward. The motion of the connecting link 66 rotates the slide link 62 counterclockwise about the pivot 64, and also draws the transition link 50 counterclockwise about the pivot 51. These movements draw the transition plate 42 downwardly (controlled by the control link 46). The lowering of the transition plate 42 draws the rear end of the seat 110 lower, thereby increasing the pitch angle δ of the seat 110 (typically to an angle of between about 6 and 12 degrees). This movement also draws the backpost 58 and backrest 130 lower and may tilt the backrest 130 very slightly, although the backrest 130 substantially maintains the first backrest angle α.
