Abstract
A reclining mechanism for a furniture item includes support structure adapted for attachment to the furniture item, a footrest support bar connected for longitudinal movement with respect to the support structure between extended and retracted positions and actuating structure connected with the footrest support bar. The footrest support bar includes an S-shaped section and is connected to a footrest member for supporting the legs of the seat occupant. The actuating structure moves the footrest support bar along the S-shaped section between the extended and retracted positions to closely approximate a conventional footrest portion of a reclining mechanism, while presenting a simplified construction.
Description




FIELD OF THE INVENTION




This invention generally relates to reclining furniture and, more specifically, to a three-way reclining furniture item having a moveable seat, backrest and footrest.




BACKGROUND OF THE INVENTION




Conventional reclining furniture items, such as chairs, sofas and sectionals, generally have either two-way or three-way mechanisms for allowing the chair to be moved between upright and reclined positions. In a two-way mechanism, the seat is fixed to the backrest as a unitary structure so that the angle between the seat and backrest remains the same during reclining motion. If the piece of furniture has a three-way mechanism, the top of the backrest will angle downwardly and rearwardly relative to the seat as the furniture item moves from an intermediate reclined or so-called T.V. position to a fully reclined position. Likewise, the backrest will move or tilt back up as the furniture item moves from the fully reclined position to the T.V. position. Among the concerns with reclining mechanisms in general are complexity and cost issues. These mechanisms can comprise large numbers of linkages and pivots to give the desired movement to the furniture item. Understandably, the more linkages and pivot connections in a given reclining mechanism, the higher the cost of manufacture and assembly. It has also become conventional practice to design reclining mechanisms with “zero wall proximity” ability. This refers to the ability to place the item of furniture with the top of the backrest against or very close to a wall while still allowing movement of the furniture item into both intermediate and fully reclined positions without encountering interference from the wall. Generally, the addition of this feature to a mechanism has even further complicated the typical three-way reclining mechanism. Another problem associated with reclining mechanisms has been the noise that they produce in moving between the different chair positions. Again, this noise can be associated with the numerous moving linkages in the mechanisms.




There have been many attempts to incorporate rollers in reclining mechanisms in various ways to produce mechanisms allowing different movements. For example, see U.S. Pat. Nos. 3,874,724; 4,072,342; 4,364,603; 4,531,778; and 5,823,614. One area of improvement that would be desirable relates to the footrest linkage of the mechanism. Conventionally, a scissor linkage assembly has been incorporated to extend and retract the footrest. Consumers have become widely familiar and comfortable with the typical footrest movement between the retracted and extended positions. However, the linkage assemblies have high numbers of links and pivots and present exposed pinch points. Certain consumers may also find them unattractive when in the extended position.




Alternative designs have been proposed to simplify the typical footrest scissor linkage, however, none of these alternatives have been fully acceptable. For example, alternative footrest mechanism constructions are shown in U.S. Pat. Nos. 4,506,925 and 4,844,536. In general, the mechanisms shown in these patents substitute bars which carry a footrest between retracted and extended positions using linkages, rollers or both. One major drawback with previous proposals such as these is that the resulting movement of the footrest does not closely approximate the typical movement of a footrest as refined through years of reclining mechanism development. This is believed to be one reason that these alternative footrest constructions have not been accepted in the industry.




In view of various problems with reclining mechanisms, such as three-way reclining mechanisms, it would be desirable to simplify these mechanisms and make them more attractive by significantly reducing the number of linkages in the footrest support and actuation portion, while also reducing costs, noise and potential pinch points associated with the mechanisms. At the same time, it would advantageous to provide a mechanism which fully reclines in a smooth manner without significant effort by the seat occupant and without interfering with a closely adjacent wall located behind the backrest.




SUMMARY OF INVENTION




The present invention improves upon past reclining mechanisms by incorporating a simplified footrest support bar and actuating system that closely approximates the typical arc-shaped movement of an extending and retracting footrest mechanism. In the preferred embodiment, a reclining mechanism is provided for a furniture item to allow movement between upright and reclined positions. More specifically, this may include one upright position and two reclined positions, typically referred to as an intermediate reclined position or T.V. position and a fully reclined position. The reclining mechanism generally includes support structure adapted for attachment to the furniture item, and a footrest support bar connected for longitudinal movement with respect to the support structure between extended and retracted positions. In the preferred embodiment, the support structure includes a track and the footrest support bar is connected for movement along the track. At least one of the track and the footrest support bar includes an S-shaped section. A first end of the footrest support bar is adapted for connection to a footrest member for supporting the legs of a seat occupant. Actuating structure is provided and connected with the footrest support bar and operates to move the footrest support bar along the S-shaped section between the extended and retracted positions.




The actuating structure is operated by a drive mechanism located between the reclining mechanisms. The drive mechanism preferably includes a motor assembly operable to rotate a drive tube. The drive tube is operatively connected to the actuating structure. However, drive mechanisms other than a motor assembly are within the scope of the present invention.




In one advantageous and preferred configuration, the S-shaped section is on the footrest support bar. The S-shaped section of the footrest support bar functions to closely approximate the movement of a conventional footrest mechanism. Also, in furtherance of this advantage, the footrest support bar includes at least one roller attached for rotation thereto and the support structure further includes a track. The roller is mounted for movement along the track between the extended and retracted positions. In the preferred embodiment, the track includes at least one curved section between the first and second ends and, more preferably, the entire track curves upward and then downward from a rear portion to a front portion thereof.




While the support structure may take many forms, it preferably includes a seat supporting member mounted adjacent the footrest support bar in a manner allowing the actuating structure to travel along the track as the footrest support bar moves between the extended and retracted positions. The roller is attached proximate the second end of the footrest support bar and the track includes first and second stops, which may be the ends of the track, with the roller engaging the stops at the respective upright and reclined positions. In a three-way mechanism, the rollers will preferably engage the stops at the upright and intermediate reclined positions. The roller is connected for movement with the actuating structure along the track. At least one additional roller is connected to a front portion of the support structure adjacent the footrest support bar and engages the footrest support bar during movement between the extended and retracted positions. In the preferred embodiment, upper and lower rollers are connected to the front portion of the support structure. These upper and lower rollers will support and guide the footrest support bar during movement between the extended and retracted positions. Many other options, such as a zero wall proximity option, gliding option, swivel option, etc., may also be incorporated into a mechanism of the present invention.




The invention also generally contemplates a method of operating a footrest mechanism in a reclining furniture item as generally described above. The method involves maintaining the footrest in a generally vertical orientation, moving the footrest support bar simultaneously downward and outward, reorienting the footrest into an angled orientation, extending the footrest support bar through an upwardly and outward arc while the footrest moves through the angled orientation, and stopping the footrest support bar with the footrest in the generally horizontal orientation at an upper end of the arc and the footrest support bar extending between the seat and the footrest. The method further involves retracting the footrest support bar through an opposite downward and inward arc while the footrest moves through the angled orientation and moving the footrest support bar upward and inward toward the seat as the footrest approaches the seat. The footrest stops in the generally vertical orientation in a typical position tucked beneath the seat.




The invention further contemplates a reclining mechanism similar to the above-described mechanism but either alternatively or additionally including a footrest member that is connected for biased, pivotal motion with respect to the footrest actuating structure, such as the S-shaped footrest support bar. In one aspect, the footrest member is connected by at least one spring to the footrest actuating structure and the spring is mounted for movement into an over-center position for pivoting the footrest member into a leg supporting position upon extension thereof. In another aspect, the footrest member is pivotally connected to the footrest actuating structure in a pivoting fashion allowing pivoting motion in two directions whereby the front edge of the footrest member is pivotal downward in the leg supporting position and the rear edge of the footrest member is pivotal outward in the retracted position. This allows the footrest to float in a spring-biased fashion in concert with movement of the seat occupant's legs in the extended position. Also, as the footrest member is retracted against the furniture item, the rear edge of the footrest member, which becomes the upper edge in the retracted position, can pivot away from the furniture item in case of object, such as a person's body part, is caught between the footrest member and the remaining portions of the furniture item.




Additional features, objectives and advantages of the invention will be more readily appreciated from the description to follow, taken in conjunction with the accompanying drawings and the various configurations of the invention set forth in the appended claims.

110


causes rotation of the bell crank link


114


located outside of the seat link/plate


22


in the direction of arrow


144


(see FIG.


4


). Rotation of the bell crank link


114


causes the connecting link


118


to pull forwardly. The forward motion of the connecting link


118


causes the drive link


122


to rotate about a horizontal axis at pivot connection


130


. Spring


138


helps pull the drive link


122


forwardly. As the drive link


122


moves forwardly, the secondary drive link


124


pulls forwardly as well, causing the S-shaped footrest support bar


26


to move forwardly.




During movement from the fully upright position shown in

FIG. 1

to the T.V. position shown in

FIG. 2

, the drive link


122


rotates until it abuts a stop


146


which extends outwardly from the seat link or plate


22

.





FIGS. 7 and 8

illustrate the drive assembly


112


referred to above. The drive assembly


112


is located between the two opposed reclining mechanisms


20


. The preferred embodiment of drive assembly


112


is a motor assembly


150


. While many different motor assemblies may be used, one which has proven satisfactory is model 9.25.000.080.30 manufactured by OKIN, Antriebstechnik GmbH & Co. in Gummersbach, Germany.




The motor assembly


150


is pivotally secured at


152


to cross tube


102


by brackets


154


. The motor assembly


150


comprises a motor


152


, a drive housing


156


extending forwardly from the motor


152


and a movable housing


158


which travels the length of the drive housing


156


. A pair of spaced L-shaped brackets


160


are secured to the sides


162


of the housing


158


and to the drive tube


110


.




Upon activation of the motor


152


, a threaded drive shaft inside drive housing


156


rotates, causing the housing


158


which has a threaded nut or block (not shown) therein to travel forwardly along the drive housing


156


. The forward motion of the housing


158


causes the L-shaped brackets to rotate the drive tube


110


in the direction of arrow


164


(see FIG.


7


).

FIG. 7

illustrates the drive assembly


112


when the reclining mechanisms


20


are in the closed and tv positions, the tv position being illustrated in phantom.

are in the fully reclined position.





FIGS. 9A-9C

illustrate the mounting and various possible movements of footrest


16


at the end of footrest support bar


26


. Bracket


34


has a generally planar first portion


43


secured to the underside of footrest


16


and a generally planar second portion


46


extending downwardly therefrom. A spring


44


is connected to the first portion


43


of bracket


34


and further connected to a stud


48


extending from the end portion


28


of footrest support bar


26


. Spring


44


is disposed above pivot


32


between bracket


34


and support bar


26


in essentially an on-center position when footrest


16


is in a retracted position. Spring


44


moves to an over-center position under the weight of a seat occupant's legs as footrest


16


moves to the extended position as shown in

FIGS. 2 and 9C

. Once in this position, footrest


16


can float in accordance with leg movement of the seat occupant in a manner described below.




Footrest


16


is mounted on a support bracket


34


connected for pivotal movement on the end of support bar


26


by way of pivot


32


. As shown in

FIG. 9A

, with footrest


16


in the retracted position, spring


44


is essentially on-center with pivot


32


. As footrest


16


is extended in the direction of arrow


166


, spring


44


moves to an over-center position as shown in

FIG. 9C

thereby automatically flipping footrest


16


into a horizontal leg supporting position.




As further shown in

FIGS. 9A-9C

, a pair of studs


170


,


172


extend outwardly of the second portion


46


of bracket


34


. One of the studs


170


engages a groove


174


formed in the extension


30


. The other stud


172


engages a groove


176


formed in the end portion


28


of the footrest support bar


26


. The engagement of the stud


170


and the groove


174


allows a top edge


16




a


of footrest


16


to rotate outward about pivot


178


in the direction of arrow


168


from the furniture item when footrest


16


is in the retracted, vertically oriented position. Therefore, footrest


16


will pivot away from any object or body part entrapped between footrest


16


and the remainder of the furniture item when moving into the fully upright position. This pivoting motion occurs without interference from the remainder of furniture item


10


(FIG.


1


).




Referring to

FIG. 9C

, the engagement of the stud


172


and the groove


176


allows downward movement of the footrest


16


in the direction of arrow


180


when footrest


16


is in the extended, horizontally oriented position. The extension


30


and footrest


16


rotate about pivot point


32


, the stud


172


traveling in the groove


176


.




Operating furniture item


10


to move between three different positions will be understood generally with reference to

FIGS. 1-6

. In the fully upright position shown in

FIGS. 1 and 4

, footrest


16


is maintained in a generally vertical orientation, but may pivot as shown in FIG.


9


B. To move furniture item


10


to the intermediate reclined or T.V. position shown in

FIGS. 2 and 5

, the seat occupant activated the drive assembly


112


to rotate the drive tube


110


.




As further shown in

FIG. 5

, the above-described movement of actuating structure


113


extends footrest support bar


26


and footrest


16


as best shown in FIG.


2


. Footrest


16


initially moves downward and then moves in an upward arc to the extended position. During extension, footrest


16


is also pivoted about pivot connection


32


to the generally horizontal orientation shown in FIG.


2


. This occurs by the over-center spring action discussed in connection with

FIGS. 9A and 9C

. During the extension of footrest support bar


26


, the S-shape of bar


26


in concert with the shape of slot


38


imparts a natural and comfortable movement to footrest


16


between the retracted and extended positions. To further move mechanism


20


into the fully reclined position shown in

FIGS. 3 and 6

, the seat occupant applies reward pressure against backrest


12


(

FIG. 1

) thereby pivoting backrest link


58


as shown in FIG.


3


. Through the backrest linkage


24


and the connection with base link


88


provided through link


72


, this forces seat link plate


22


and the attached link


94


and rollers


106


,


108


to move in a forward direction. Rollers


106


,


108


travel up tracks


84


,


86


. The full reclining movement is stopped when rollers


106


,


108


reach the ends of respective tracks


84


,


86

While the present invention has been illustrated by a description of a preferred embodiment and while this embodiment have been described in considerable detail in order to describe the best mode of practicing the invention, it is not the intention of applicant to restrict or in any way limit the scope of the appended claims to such detail. As some examples, the various linkage configurations, connections, etc., may differ significantly from mechanism to mechanism. A connection between two elements need not be a direct connection but may be a connection made through other structure. Also, with respect to the S-shaped section of the footrest support bar or the contemplated S-shaped track, although the preferred support bar is shown with an overall gradual, continuously curving S-shape, this term is meant to include other generally S-shaped configurations, including those having straight end portions, for example, or other curving portions. In combination with the curved track, the disclosed configuration is deemed to provide a desirable footrest movement. The configuration also functions well if the track is generally straightened except for a downwardly curved front end portion. Other combinations of curved track and support bar sections, for example, in combination with a linkage assembly may work as well while retaining the general inventive apparatus and method. Additional advantages and modifications within the spirit and scope of the invention will readily appear to those skilled in the art.
