Definitions

  • This invention relatesto.lockingmechanism for reclining chairs and for so-called rocker-recliner chairs,-i.e., reclining chairs which are built on rocking bases. All suchchai'rsinclude aretractable footrest to support the legsof the occupant, and the operation of our locking mechanism is arranged to occur as an incident to extension and retraction of the footrest, and to prevent independent'i'etraction of the footrest while the chair is reclined, but to effect a slight a-nddesirable related retraction thereof as the chair is reclined.
  • the invention is more particularly concerned with a selective locking mechanism which prevents the recline of the chair in advance of the extension of the footrest, and which, in a rocker-recliner chain prevents reclining when the chair isadjusted for rocking, and conversely prevents rocking when-the chair is reclined.
  • the invention contemplates the selection within the profile of the chair of a given common point on the reclining mechanism and on the chair base from which a substantial relative movement will be experienced when the chair is reclined.
  • the rocker-recliner chair it is further contemplated that there will be located within the chair profile not only a given commonpoint from which the reclining mechanism will have a substantial movement relative to the rocker portion of the base when the chair is recline, but also another given point common to the rocker and to the fixed base when the chair is in neutral balance, and from which the rocker will have a substantial movement relative to the fixed base when the chair rocks, neutral balance" meaning the upright sitting of the chair, rocked neither forward nor back.
  • each of the relatively movable chair members e.g., the reclining mechanism and the fixed base of the ordinary reclining chair
  • one of a pair of connected -the"given common point on the rocking and fixed portions of the base may be se lected to coincide in a single point, permitting both links pivoted to the rocker to be unified into a single locking lever connected by one link to the fixed base of the. chair and by a second link to the recline linkage, and shiftable between two alternate positions.
  • each connected link pair permits permits relative movement of its associated chair portions locking lever occupies its alternate position, its other arm andthe link connecting the same to the fixed portion'of the base of the chair are swung into alignment to prevent rocking in either direction from neutral balance, while the locking lever and its link connection to the recline mechanism, having had their common pivot moved into coincidence with the axis of the movement of that mechanism upon recline, permit the reclining movement, and likewise toggle as the reclining movement proceeds.
  • FIG. 1 is an exploded isometric assembly view of the locking linkage of our invention in its more complete form, one of a pair that we prefer to employ, one at each side of the chair, to lock the rocker of a rockerrecliner securely for the recline of the chair when the footrest is extended, and to prevent retraction of the footrest when the chair is reclined, FIG. 1 showing the normal positions of the parts, i.e., with the chair in neutral balance and the footrest retracted;
  • FIG. 2 is a diagrammatic side elevation of the chair showing the locking linkage positioned within the chair profile
  • FIG. 3, 4 and 5 are enlarged fragmentary side elevations of our locking linkage, FIG. .3 showing the same in the position of FIG. 1 to facilitate orientation, and FIGS. 4 and 5 showing the chair rocked backward and forward, respectively, as permitted by the position of the lockinglinkage illustrated in FIGS. 1, 2 and 3;
  • FIG. 6 is a diagrammatic side elevation of the chair showing the footrest extended
  • FIG. 7 is a corresponding fragmentary side elevation of the locking linkage positioned by the extension of the footrest to prevent rocking and to permit the reclining action to proceed;
  • FIG. 8 is a diagrammatic side elevation of the chair both upright and in recline
  • FIG. 9 an enlarged fragmentary side elevation of the locking linkage positioned by the recline to prevent retraction of the footrest.
  • the angle bracket 16 being secured to the rocker 20 and employed as the locking point thereof, moves up and down relative to the fixed base 14 and, because the rocker travels fore and aft on its base while rocking, describes a curvilinear path that is not a circular arc.
  • the lockable member of the reclining mechanism on the other hand, the upstanding boomerang-shaped link 24, is pivoted on the rocker bracket 18, and is independently rotatable thereon during the reclining movement of the chair.
  • the locking members per se of the locking linkage 10 include a rocking, bell-crank lock lever 28 pivoted to the angle bracket 16 on the rocker, a slotted link 30 by means of which one arm 32 of the lock lever 28 is connected to the fixed bracket 12 secured to the base of the chair, and another link 34 by means of which the other arm 36 of the lock lever 28 is connected to the rearwardly extending arm 38 of the boomerang lever 24 which supports the back of the chair.
  • Extension of the footrest with the chair in the upright position, and blocked against rocking has become identified in trade parlance as the TV position, the extension of the footrest being accomplished either by manipulation of a hand lever at the side of the chair, or by a shifting of the chair seat relative to the rocking portion of the base.
  • the connecting link 42 by means of which the lock lever 28 of our locking linkage is positioned to prevent rocking, would be connected for actuation by and coincident to the shifting of the seat on the rocking base, either by more direct connection to the seat, or indirectly, as shown, by operation of the footrest mechamsm.
  • rocker bracket 18 of angle iron Screwed onto the rocker portion 20 of the base is the rocker bracket 18 of angle iron which provides the mounting for the recline linkage by means of which the back of the chair and the seat are mounted for movement relative to each other and to the rocking portion of the base as an incident to recline of the chair.
  • the recline linkage illustrated in FIG. 1 is that which is illustrated, described, and claimed in our co-pending application Ser. No. 374,355, filed June 28, 1973, and is reshown here simply for purposes of illustration.
  • back bracket 26 which-in turn is supported from the aforementioned rocker bracket 18 by means of the link 22 and lever 24, which form a trapezoidal linkage with the back bracket 26 and the rocker bracket 18 to effect a forward lifting of the back bracket 26 (andthe lower end of the back of chair) as an incident to the rearward rotation of the back-bracket upon recline.
  • the seat of the chair is' supported upon the seat bracket 48, which in turn is supported in its forward portions by an overslung link 54 extending upwardly and rearwardly from its pivotalconnection to the rocker bracket 18 to its pivotal connection in the seat bracket 48. Its angularity in the sitting position illustrated is such that when the seat bracket is shifted forv wardly, the link 54 lifts the front end of the seat.
  • the rearward portion of the seat is carried upon a bell crank lever 56 supported from the front, boomerang-shaped back-support lever 24 and controlled in its movement relative thereto during the recilining rota tion of the back by a control link 58 connected to the back bracket 36.
  • That specific reclining chair mecha- The footrest extension mechanism-'0 (FIG. 6)
  • FIG. 1 largely omitted from FIG. 1 except to the extent it shares parts in common with the locking linkage 10, in particular, those parts necessary to operate the locking linkage to prevent rocking coincidentally with the extension of the retractable footrest to its forward position. Still referring to FIG. 1, these include the square cross shaft 46 journalled forwardly on the seat bracket 48 and extending to a seat bracket counterpart on the other side of the chair to unify the action of the footrest extension linkages 50 on opposite sides of the chair.
  • the foorest 60 is extended on a pair of parallel rails 62' which are suitably supported from the underside of the seat of the chair for endwise movement,and are propelled to the extended position by a drive linkage comprising a hand lever operated rear drive link 64 pivoted to the seat bracket 48, a forward drive link 66 secured as an arm to the aforementioned square cross shaft 46 shown in FIG. l, and connected for unison rotation by a connecting link 68.
  • the rocker portion of the base and everything supported by it oscillates up and down and to and fro relative to the fixed base 14, whereas in the reclining mode, the seat and the back, or in any event the back, move relative to the rocker 20 upon which they are mounted.
  • the rocker portion of the base and everything supported by it oscillates up and down and to and fro relative to the fixed base 14, whereas in the reclining mode, the seat and the back, or in any event the back, move relative to the rocker 20 upon which they are mounted.
  • locking linkage of our invention is such that when the footrest is retracted and the chair is in upright sitting position, the linkage permits rocking but prevents recline. On the other hand, when the footrest is extended, the rocking movement is blocked, and the locking linkage conditioned to permit recline. This is the so-called intermediate or TV position, i.e., with footrest extended, rocking function locked, and the chair conditioned for recline.
  • the locking linkage operates to perform a slight but related retraction of the footrest, but prevents independent retraction of the footrest while the chair is reclined.
  • the lower shorter arm 38 of the boomerang-shaped front support lever 24 of the back is in alignment with the rocker bracket 18 when the back is in the upright sitting position, being supported in that attitude by the angle bracket 16 which is secured to the underside of the rocker bracketl8 and extends inwardly therefrom to space its upstanding flange from the vertical flange of the rocker bracket.
  • the ver tical flange of the angle bracket 16 is pierced to receive a shoulder rivet to pivot the rock lever 28 on the rocker portion of the base.
  • the rearwardly-extending shorter arm 38 of the forward back support lever 24 is pierced at a point spaced rearwardly from'its pivotal attachment to the rocker bracket 18, and on an axis which coincides with the pivotal mounting of the lock lever 28 when the chair parts are in the upright position illustrated in FIG. 1.
  • This provides the pivotal mounting for the connecting link 34, which for other purposes yet to be described, is also formed as a bell crank, i.e., having two diverging arms. The one of those arms, 37, standing nearly upright in FIG.
  • I is pivotally connected at its upper end to the similarly upstanding and coextensive arm 36 of the lock lever 28, both said arms being offset toward each other to bridge the angle bracket 16 and the clearance space provided, and being pierced and pivotally connected by a suitable. shoulder rivet.
  • the fixed bracket 12 is formed with a short upstanding mounting flange 76 emplaced against the inner surface of the runner of the base 13, and a taller upstanding plate 78 spaced therefrom adequately to span the angle bracket 16 of the rocker and all of the locking linkage.
  • the plate 78 supports a shoulder bolt 80 on which the slotted end of the connecting link 30 is pivoted, coaxially with the pivot of the lock lever 28 to the angle bracket 16, and with the pivot of the rearwardly extending arm 38 of the forward back-support lever 24 to its connecting link 34. That is to say, when the chair is in neutral balance, the pivot axes of the fixed bracket 12, the lock lever 28 on the angle bracket 16, and that of the connecting link 34 to the rearwardly extending arm 38 of the forward back support lever 24,
  • the mounting flange 76 of the fixed bracket 12 ' is provided with two holes spaced from front to rear, the forward hole being tapped to receive a mounting screw (not shown) passed through a drilled hole in the runner of the base 14.
  • the rearward hole of the mounting flange is pierced oversize and an aligned tapped hole provided in the spaced upstanding plate 78 that supports the pivot bolt 80.
  • a longer mounting screw 82 is passed through the base runner from the outside, through the rear hole in the mounting flange 76, and fitted in the tapped hole .in the upstanding plate 78.
  • This rearward screw may, if desired, be a shoulder screw, or may be surrounded by a sleeve between the two upstanding flanges of the fixed bracket 12, as maybe desirable to enable the screw 82 to provide a stop for the slotted link 30 and the lock lever 28 in the alternate position of adjustment of the latter, at which the rocking'of the chair is prevented and recline permitted (FIG. 7).
  • the coinciding lengths of the arm 36 of the lock lever 28 and the arm 37 of the connecting link 34, shown upstanding in FIG. 1, are also equal to the distance between the two pivots of the shorter arm 38 of the forward back support lever 24, so that when the locking linkage is shifted to its alternate position (FIG. 7), not only will the rocker portion of the base be secured in the neutral balance position of FIG. 1, but the pivot axis of the connection of the lock lever 28 to the connecting link 34 will coincide with the axis of the pivotal connection of the forward back support lever 24 to the rocker bracket 18, and with the parts thus aligned, the forward back support lever 24 may swing freely upwardly to permit the chair to recline.
  • the shifting of the locking linkage between its alternate positions by the swinging of the lock lever 28 is accomplished as already indicated by the same action which extends the footrest and specifically, in the illustrated instance, is effected by the rotation of the square cross shaft 46 journalled in and extending between the seat brackets 48 at opposite sides of the chair.
  • the rotation of the cross shaft 46 is imparted to the short arm 44 secured thereto, the arm 44 being stamped from light plate and pierced with a square hole at one end to receive the shaft 46 and a round hole at the distal end forpivotal attachment by means of a suitable rivet to the rearwardly-extending operating link 42.
  • the operating link 42 is preferably tubular for greater rigidity, and flattened at its ends for connection forwardly to the arm 44 on the cross shaft 46, and rearwardly to the locking linkage 10.
  • the primary function of the operating link 42 is to shift the lock lever 28 between its alternate positions.
  • the link might suitably be connected directly to the lock lever 28 at any convenient point thereon or'extension thereof, depending upon the direction of movement of the conveniently available shifting effort derived from the extension of the footrest.
  • TI-IE OPERATING LINKAGE PER SE lock lever 28 The slotted connecting link 30 and its associated arm 32 of the lock lever 28 are likewise offset toward each other at their distal ends to provide clearance for the flattened rear end of the operating link during rocking movement of the chair.
  • the primary or lever-shifting function of the operating link 42 can occur freelyonly when the chair is in its position of neutral balance, or more precisely, when the pivot on the angle bracket 16 and at the rear end of the lower arm 38 of the forward back-support lever 24 coincide with the pivot on the fixed bracket 12, or nearly so. (The ability of the locking linkage to jack the chair into neutral balance upon attempted extension of the footrest is discussed later herein.)
  • the rotation of the cross shaft 46 by the extension of the footrest moves the operating link 42 forwardly, and rotates the connecting link 34 clockwise as viewed in FIG. 1, carrying with it the lock lever 28, which in turn carries with it the slotted connecting link 30, turning all parts to the position of FIG. 7 coincident with the extension of the footrest. From the position of FIG.
  • the reclining motion may proceed at the occupants discretion, inasmuch as the aligned arm 37 of the connecting link 34 and arm 36 of the lock lever 28 have been moved into alignment with the shorter arm 38 of the forward back support lever 24, and their connecting pivot is aligned with the swing pivot of the back-support lever on the rocker bracket 18.
  • the tubular operating link 42 is moved forwardly as the connecting link 34 rotates clockwise (as seen in FIGS. 1 and 9) with the back support lever 24.
  • This forward 9 movement of the operatinglink 42 relative to the rocker upon-recline enables it to perform a secondary function now to-be described.
  • the same retraction control can be achieved equally in chairs having no movement, or a different movement, of the footrest mechanism relative to the chair upon recline, by attaching the operating link 42of the locking mechanism appropriately to the connecting link 34.
  • FIG. 3 which is a side elevation ofthe locking linkage in the same position illustrated in FIG. 1, the chair is in neutral balance in the upright sitting position, rocked neither forward nor back, although capable of doing so but incapable of reclining.
  • slotted connecting link 30 and its associated arm 32 of the lock lever 28 simply toggle idly in their passage from the position of FIG. 4 to that of FIG. 5, and vice versa, passing on each rocking movement through the neutral position of FIG. 3.
  • the path described by the axis of the lock lever is a compound movement rather than a circular arc, 'wherefore it is accordingly necessary to provide a slot in the link 30 at the pivot bolt 80 to accommodate these slight fore and aft movements of the rocker on the base.
  • CONCLUSION modate to specifically different chairs, or the unified preferred locking linkage might be located forwardly of the rocking fulcrum and its connection to the recline mechanism of the chair made to the seat or to the seat supports if the same move relative to the rocker upon recline.
