This invention relates generally to seating units, and relates more particularly to reclining seating units with rocking capability.
Recliner chairs and other reclining seating units have proven to be popular with consumers. These seating units typically 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 matching reclining mechanisms that are attached to the seat, backrest and base of the chair.
In recent years, furniture designers have looked for alternatives to rocking chairs that can provide a similarly relaxing repetitive motion. One alternative has been the gliding chair, or “glider”, which includes structure that enables the seat portion of the chair to “glide” forwardly and rearwardly relative to its base to mimic generally the rocking motion of a rocking chair. Often the gliding structure comprises a set of swing links (usually two at the front of the chair, and two at the rear) that are pivotally attached at their upper ends to the base and extend downwardly therefrom to attach to a structure, such as a mounting bracket, that is attached to the seat. In this configuration, the seat is suspended from the base and is free to swing forwardly and rearwardly in a double pendulum-type motion in response to a forwardly or rearwardly-directed force applied by a seated occupant. The gliding path of the chair is controlled by the configuration and mounting of the swing links. These chairs can be constructed to resemble traditional rocking chairs and thus are quite popular.
Reclining capability has been combined with gliding capability in a single unit to provide a chair that both reclines and glides. This chair includes a reclining mechanism that enables it to move between upright and one or more reclined positions, and further includes the aforementioned swing links attached between the base and the seat, armrests, or mechanism itself to enable the chair to glide. Examples of such chairs are illustrated and described in U.S. Pat. Nos. 4,536,029 and 4,544,201, both to Rogers, Jr., the disclosures of which are hereby incorporated herein by reference in their entireties. Other examples are shown in U.S. Pat. No. 7,997,644 to Hoffman et al. and co-pending and co-assigned U.S. patent application Ser. No. 12/941,303 to Murphy et al., the disclosures of each of which is hereby incorporated herein in its entirety.
Although they are already popular seating units, it may be desirable to provide additional functionality to glider-recliners.
As a first aspect, embodiments of the invention are directed to a gliding reclining seating unit. The seating unit comprises: a base; a frame with opposed arms; a gliding mechanism attached to the frame and the base, the gliding mechanism configured to enable the frame to glide longitudinally relative to the base; a seat; a backrest; an ottoman; a reclining mechanism comprising a plurality of pivotally interconnected links and attached to the frame, seat, backrest and ottoman, the reclining mechanism being configured to move the seating unit between (a) an upright position, in which the seat is generally horizontally disposed, the backrest is generally vertically disposed, and the ottoman is generally vertically disposed and positioned below the seat, (b) an intermediate TV position, in which the ottoman is generally horizontally disposed in front of the seat and the backrest and the seat substantially maintain the same relationship as they have in the upright position, and (c) a fully reclined position, in which the angle between the backrest and the seat increases; and a glide stop unit that prevents the frame from gliding rearwardly relative to the base when the seating unit is in the TV and fully reclined positions. The seating unit is actuated for movement from the upright position to the TV position via an occupant of the chair pushing on the arms of the frame.
As a second aspect, embodiments of the invention are directed to a gliding reclining seating unit, comprising: a base; a frame with opposed arms; a gliding mechanism attached to the frame and the base, the gliding mechanism configured to enable the frame to glide longitudinally relative to the base; a seat; a backrest; an ottoman; a reclining mechanism comprising a plurality of pivotally interconnected links and attached to the frame, seat, backrest and ottoman, the reclining mechanism being configured to move the seating unit between (a) an upright position, in which the seat is generally horizontally disposed, the backrest is generally vertically disposed, and the ottoman is generally vertically disposed and positioned below the seat, (b) an intermediate TV position, in which the ottoman is generally horizontally disposed in front of the seat and the backrest and the seat substantially maintain the same relationship as they have in the upright position, and (c) a fully reclined position, in which the angle between the backrest and the seat increases; and a glide stop unit that prevents the frame from gliding rearwardly relative to the base when the seating unit is in the TV and fully reclined positions. The seat moves rearwardly from the upright position to the TV position a sufficient distance that the weight of a seated occupant substantially prevents forward longitudinal movement of the frame relative to the base.
As a third aspect, embodiments of the invention are directed to a gliding reclining seating unit, comprising: a base; a frame with opposed arms, the lowermost portion of the arms being raised from the floor such that the seating unit is a high leg seating unit; a gliding mechanism attached to the frame and the base, the gliding mechanism configured to enable the frame to glide longitudinally relative to the base; a seat; a backrest; an ottoman; a reclining mechanism comprising a plurality of pivotally interconnected links and attached to the frame, seat, backrest and ottoman, the reclining mechanism being configured to move the seating unit between (a) an upright position, in which the seat is generally horizontally disposed, the backrest is generally vertically disposed, and the ottoman is generally vertically disposed and positioned below the seat, (b) an intermediate TV position, in which the ottoman is generally horizontally disposed in front of the seat and the backrest and the seat substantially maintain the same relationship as they have in the upright position, and (c) a fully reclined position, in which the angle between the backrest and the seat increases; and a glide stop unit that prevents the frame from gliding rearwardly relative to the base when the seating unit is in the TV and fully reclined positions. The seating unit is actuated for movement from the upright position to the TV position via an occupant of the chair pushing on the arms of the frame.
The present invention will be described more particularly hereinafter with reference to the accompanying drawings. The invention is not intended to be limited to the illustrated embodiments; rather, these embodiments are intended to fully and completely disclose the invention to those skilled in this art. In the drawings, like numbers refer to like elements throughout. Thicknesses and dimensions of some components may be exaggerated for clarity.
Well-known functions or constructions may not be described in detail for brevity and/or clarity.
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 relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
In addition, spatially relative terms, such as “under”, “below”, “lower”, “over”, “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the exemplary term “under” can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
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 expression “and/or” includes any and all combinations of one or more of the associated listed items.
Where used, the terms “attached”; “connected”, “interconnected”, “contacting”, “coupled”, “mounted” and the like can mean either direct or indirect attachment or contact between elements, unless stated otherwise.
In addition, some components of the seating units described herein (particularly mechanisms thereof) are illustrated herein as a series of pivotally interconnected links or members. Those skilled in this art will appreciate that the pivots between links or other components can take a variety of configurations, such as pivot pins, rivets, bolt and nut combinations, and the like, any of which may be suitable for use with the present invention. Also, the shapes and configurations of the links themselves may vary, as will be understood by those skilled in this art. Further, some links may be omitted entirely in some embodiments, and additional links may be included in some embodiments.
Referring now to the drawings, a chair, designated broadly at 10, is illustrated in
The base 2 includes a pair of leg members 12 that rest on the underlying surface. A mounting bracket 13 is fixed to the upper surface of each leg member 12; cross-members 14 extend between and are fixed to the mounting brackets 13. A second mounting bracket 15 is mounted on top of each mounting bracket 13.
The frame 3 includes arms 18 that have outer panels 17 and inner panels 19. A cross-member 16 spans the rear portions of the arms 18, and spacers 16a span the front portions of the outer and inner panels 17, 19 of each arm, thereby creating a cavity 18a within each arm 18.
The gliding mechanism 7 includes pairs of front glide links 20 and rear glide links 25. Each front glide link 20 is pivotally mounted to the mounting bracket 15 at a pivot 21 and extends downwardly therefrom, and each rear glide link 25 is pivotally mounted to the mounting bracket at a pivot 26. At their lower ends, the front and rear glide links 20, 25 are pivotally mounted at pivots 27, 28 to a mounting bracket 31 that is mounted to the outer surface of the inner panel 19 of each arm 18, such that the glide links 20, 25 reside within the gap 18a of each arm 18.
The gliding mechanism 7 also includes a glide stop unit 200. The glide stop unit 200 comprises an extension member 202 that is mounted to the rear glide link 25 at a middle portion thereof and extends rearwardly therefrom within the gap 18a of the arm 18. A stop member 204 is mounted to and extends transversely between the rear ends of the extension member 202 on opposite sides of the chair 1. In this embodiment, the stop member 204 has a round cross-section, but other configurations may be employed.
The seat 4 comprises a rectangular frame formed of two longitudinal rails 34 and cross-members 35. A seat mounting panel 84 is mounted to the outer surface of each of the longitudinal rails 34.
The arms 18 of the chair 1 are raised off of the floor by the leg members 12 in a style known as “high leg”, in which one or more of the legs of the chair 1 are exposed and clearly visible below the frame 3. Typically, the lower edge of each of the arms 18 is between about 2 and 5 inches from the floor.
Turning now to the reclining mechanism 8, each of the reclining mechanisms 8 is a mirror image of the other reclining mechanism about a vertical plane that extends from the front of the chair 1 to the rear centered between the arms 18. In the interest of brevity, only one reclining mechanism 8 will be described herein, with the understanding that the discussion is equally applicable to the other reclining mechanism 8. Also, the reclining mechanism 8 will be described first with respect to the fully reclined position (

A drive link 168 is attached to the front ottoman drive link 108 at a pivot 172, and extends rearwardly therefrom to a pivot 170 with the frame mounting bracket 60.
Operation of the chair typically begins in the upright position (
In the upright position, the reclining mechanism 8 is folded into a relatively small package below the seat 4 and above the lower edges of the arms 18. This is done in order to hide the reclining mechanism 8 from an observer positioned to the side of the chair 1. The height dimension of the reclining mechanism 8 in the upright position (from the lowermost portion of the mechanism 8 to the seat 4) is between about 5 and 8 inches; this dimension is smaller than that of a typical reclining mechanism because of the high-leg style of the chair 1.
The chair 1 is free to glide along a longitudinal path defined by the front and rear glide links 20, 25 with the chair 1 in the upright position (see
To move the chair 1 to the TV position of
As can be seen in
Also, the rearward movement of the seat 4 relative to the base 2 moves the weight of the occupant of the chair 1 rearwardly. This rearward movement is typically between about 2.5 and 4.5 inches, and in particular between about 3 and 4 inches. Although there is not a structural component of the glide stop mechanism 200 that prevents the seat 4 from gliding forward relative to the base 2, the weight of the occupant is positioned sufficiently rearward that, absent the occupant taking a posture in which he leans forward to the extreme, the seat 4 does not glide forwardly relative to the base 2. In some embodiments, the center of the occupant's weight is positioned rearward of the pivot 28 between the rear glide link 25 and the frame bracket 60. Thus, with an occupant in the TV position the seat 4, the frame 3, the backrest 5 and the ottomans 6a, 6b, 6c are effectively prevented from gliding motion relative to the base 2.
Further, as the seat 4 moves rearwardly, the drive link 168 rotates only slightly, with the net effect that the front ottoman drive link 108 rotates counterclockwise considerably about the pivot 110. This action also extends the front and rear ottoman extension links 118, 112, which in turn rotates the rear ottoman link 104 counterclockwise about the pivot 106. Once rotation of the rear ottoman drive link 104 causes the axis defined by the spring 105 to pass the pivot 106, the spring 105 then urges the rear ottoman drive link 104 toward the TV position. Relative separation of the front and rear ottoman extension links 118, 112 also rotates the main ottoman bracket 122 and the main ottoman 6b to a generally horizontal disposition in front of the seat 4. Extension of the front ottoman extension link 118 and rotation of the main ottoman bracket 122 also draws forward and inverts the front ottoman bracket 128 and the front ottoman 6c. Extension and separation of the front and rear ottoman extension links 118, 112 also forces the rear ottoman bracket 138 and the rear ottoman 6a upwardly and rotates the rear ottoman bracket 138 about the pivot 140. Extension of the ottomans 6a, 6b, 6c ceases when the lower edge of the front ottoman drive link 108 strikes a stop pin 112a on the rear ottoman extension link 112.

Also, although the seat 4 rises, the rear finger 62a and the stop projection 62b remain in a position to contact the stop member 204 of the glide stop unit 200. Consequently, the frame 3, seat 4, backrest 5 and ottomans 6a, 6b, 6c are still prevented from gliding rearwardly relative to the base 2, and the rearward position of the seat 4 inhibits forward gliding motion absent the occupant taking an extreme forward-leaning posture.
The chair 1 can be returned to the TV and/or upright position by the occupant pushing downwardly with his feet on one or more of the ottomans 6a, 6b, 6c or by pulling rearwardly on the arms 18. The links of the reclining mechanism 8 will reverse the various movements described above.
Those skilled in this art will recognize that the reclining mechanism 8 may be employed with a variety of reclining seating units, including sofas and sectional units, including those that have fewer, or even no, ottomans or arms. Also, the reclining mechanism may be employed with seating units that actuate in different ways, such as handles, release levers, and the like.
The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. Although exemplary embodiments of this invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention.
