Definitions

  • This invention relates to reclining chair fixtures, and more particularly to a three position, high leg type fixture, the term three position meaning that the fixture will support a chair seat and leg rest in any of three rest positions relative to a stationary base, while the term high leg means that in the normal rest position of the chair the leg rest is retracted upwardly beneath the seat so that a substantial clearance is achieved between the floor and the lower surfaces of the seat and leg rest.
  • the leg rest of a reclining chair in order to be comfortable to the occupant, must be a substantial width, and to conceal the leg rest when the chair is in a normal position, practically all high leg fixtures are designed to swing the leg rest into a substantially horizontal downwardly facing position underneath the front portion of the chair seat when the chair is in its normal upright position.
  • the fixture In order to shift the leg rest into a leg supporting position in front of the chair seat, it is necessary not only to project the leg rest forwardly from its retracted position, but also to swing the leg rest in an arc of 180 so that it faces upwardly when in the leg supporting position.
  • the fixture In addition to being capable of the foregoing action, the fixture must be designed so that it is extremely compact when the leg rest is in its retracted position in order that the links of the fixture may be concealed from view.
  • Another object of the invention is to provide a three position high leg reclining chair fixture in which the leg rest is shifted from a retracted position into leg supporting relationship with the chair seat in response to a slight reclining movement of the chair seat.
  • Still another object of the invention is to provide a reclining chair fixture which is extremely compact and easily concealed when the chair is in the normal position.
  • a reclining chair fixture which includes a control link pivoted intermediate its ends upon a fixed base link.
  • a seat link is supported for compound pivotal movement relative to the base link and the rearward end of the seat link is coupled by a connecting link to one end of the control link.
  • the opposite end of the control link is coupled by either of two variant forms of linkage to both the front portion of the seat and to the leg rest. Both forms of linkage are so arranged that as the leg rest is swung into leg supporting relationship with the seat, the reaction of the weight of the occupants legs upon the leg rest is applied to the control link in opposition to the forces applied to the rearward portion of the seat by the occupant.
  • the self balancing action is attained by employing a relatively short lever arm on the control link between its fixed pivot and the connecting link which couples the control link to the rear portion of the seat and providing a relatively long lever arm on the control link between the fixed pivot and that end of the control link coupled to the forward portion of the seat and the foot rest.
  • This disparity in the length of the respective lever arms not only enables the relatively small portion of the weight of the occupant exerted against the leg rest to counterbalance the larger portion of weight exerted by the occupant on the seat, but also greatly magnifies the amount of movement of the leg rest occasioned by a given amount of movement of the chair seat relative to the base.
  • the leg rest is constructed in two parts, one part being located in a substantially horizontal downwardly facing position beneath the front portion of the chair seat when retracted with the other part disposed in a vertical position defining a downward continuation of the chair seat to conceal the front edge portion of the first part.
  • FIG. 1 is a side elevational view of one form of fixture embodying the invention showing the fixture in its contracted position with adjacent portions of the chair indicated in broken line;
  • FIG. 2 is a plan view of the fixture of FIG. 1 in its contracted position
  • FIG. 3 is a side elevational view of the fixture of FIG. 1 showing the fixture in an intermediate reclined position;
  • FIG. 4 is a side elevational view of the fixture in FIG. 1 showing the fixture in its fully reclined position;
  • FIG. 5 is a side elevational view of an alternative form of fixture embodying the invention showing in full line the fixture in its intermediate reclined position and showing in broken line the position of the fixture in its fully reclined position;
  • FIGS. 6A, 6B and 6C are side elevational views showing the relationship between the stationary base, seat unit and foot rest of a chair employing either of the foregoing fixtures respectively in the normal, intermediate reclined and fully reclined position;
  • FIG. 7 is a partial cross-sectional view, generally similar to FIG. 1, showing the front portion of the fixture of FIG. 1 provided with a two-part leg rest;
  • FIG. 8 is a partial side elevational view of the leg rest structure of FIG. 7, showing the structure in the intermediate reclined position;
  • FIG. 9 is a side elevational view, similar to FIG. 8, but showing the leg rest structure of FIG. 7 in the fully reclined position.
  • the preferred form of fixture includes a rigid base link it which is adapted to be fixedly attached to a side frame member such as 12 (FIG. 1) of the stationary base B of a reclining chair by any suitable means such as mounting bolts (not shown).
  • Base link may be cut away at suitable locations such as 14 to accommodate transversely extending cross frame members such as 16 (FIG. 1).
  • a fixed pivot 18 is mounted on base link 10 to pivotally support a rear support link 2t) for movement upon base link.
  • the upper end of rear support link 20 is connected by a pivot 22 to the rearward end of a seat link 24 which is adapted to be fixedly secured as by mounting bolts (not shown) to a side frame member 26 of the seat unit S of the reclining chair.
  • a front fixed pivot 28 supports a front support link 30 for pivotal movement on the base link.
  • a pivot 32 pivotally connects the remote end of link 30 to one end of a second front support link 34 pivotally connected at its opposite end to a front seat pivot 36 on the forward end of seat link 24.
  • a third fixed pivot 38 located on base link it) between front fixed pivot 28 and rear fixed pivot 13 supports a control link 40 for pivotal movement upon base link 19.
  • Control link 49 is mounted at an intermediate location upon pivot 38 and is connected at one end by a pivot 42 to one end of a rear connecting link 44.
  • the opposite end of rear connecting link 44 is connected, to pivot 22, for pivotal movement relative to both rear support link 20 and seat link 24.
  • control link 40 is connected by a pivot 46 to one end of a leg rest control link 48.
  • a leg rest link 5t adapted to be fixedly attached to the leg rest L of the reclining chair, is mounted upon the opposite end of leg rest control link 48 by a pivot 52.
  • a second leg rest control link 54 is connected at one end to a second pivot 56 on leg rest link 54 and is connected at its opposite end by a pivot 58 to a projection 60 on front support link 30 at a location intermediate the ends of support link 30.
  • leg rest control link is likewise connectet to an intermediate location on front support link 33 by a pivot 62 to function as a front connecting link connecting one end of control link 40 to the linkage supporting the front end of seat link 24.
  • Two positive stops are employed to determine the contracted or normal position of the linkage as shown in FIG. 1 and the fully reclined position of FIG. 4.
  • the contracted or normal position of the linkage is established by the engagement between an offset portion 64 on seat link 24 with a projection 66 which defines the extreme forward end of base link 10.
  • a stop pin 68 is fixedly mounted on base link It) to project into the path of the lower end of control 40 to engage the control link when the fixture arrives at the fully reclined position of FIG. 4.
  • the linkage described above supports leg rest L for swinging movement through an arc of substantially upon movement of the chair seat S from the normal or upright position of FIG. 6A to the fully reclined position of FIG. 6C which corresponds to the position of the fixture shown in FIG. 4.
  • the fixture is so designed that it is positively maintained in the positions of FIG. 6A and FIG. 6C by the normal forces applied to the fixture by the occupant of the chair.
  • the intermediate reclined position of FIG. 6B (corresponding to the position of the fixture in FIG. 3) is what is best described as a self balanced position in that it is established by balancing the weight exerted by the chair occupant on the seat unit against the weight of the occupant applied to leg rest L.
  • leg rest L and seat unit S in the intermediate reclined position may vary somewhat for different occupants of the chair, depending upon the relative percentages of the occupants weight which is applied respectively against the leg rest and seat.
  • This self-balancing action is achieved in the fixture by applying the forces respectively exerted upon the chair seat and upon the leg rest to opposite ends of control link 40 in opposition to each other.
  • a force exerted on leg rest link 50 in a generally downward direction is transmitted by leg rest control link 48 to the lower end of control link 40 in a direction tending to rotate control link 4-0 in a counterclockwise direction about fixed pivot 38.
  • a downward force on seat link 24 tends to rotate rear support link 20 in a clockwise direction about pivot 18 thus urging connecting link 44 rearwardly which, through pivot 42, tends to rotate control link 40 in a clockwise direction about pivot 38.
  • the action of the fixture is best appreciated by following relative movement of the various parts of the fixture as the chair is successively shifted from the normal position of FIG. 6A to the semi or intermediate reclined position of FIG. 6B and finally to the fully reclined position of FIG. 6C.
  • leg rest L During the downward and forward swinging movement of leg rest L, the leg rest is further pivoted in a clockwise direction about pivot 56 to swing leg rest L from the downwardly facing position of FIG. 1 into an upwardly facing position as the chair linkage approaches the intermediate reclined position of FIG. 3.
  • the weight of the occupants legs begins to be applied to leg rest link 59 to resist upward movement of the leg rest and eventually a balanced position of the fixture is achieved in which the reaction of the occupants legs against the leg rest are counterbalanced about pivot 33 against the reaction of the occupants weight on seat link 24.
  • pivot 35 partakes of a substantial amount of vertical movement with a relatively small amount of horizontal movement I and thus there is a point during the movement of the chair at which the path of pivot 36 curves sharply upwardly. Since upward movement of pivot 36 is resisted by the weight of the occupant of the chair the sharp upward curve of the path of pivot 3% provides an extreme limit to the degree of reclining of the chair when in its intermediate reclined position and the self balancing action described above occurs as the fixture approaches the point at which the path of pivot 35 curves upwardly.
  • FIG. 5 a modified form of fixture is shown as in cluding a base link 11%) having a rear fixed pivot 112, a front fixed pivot 114 and an intermediate fixed pivot 116.
  • a rear support link 118 is mounted at its lower end upon rear fixed pivot 112 and is coupled at its upper end by a pivot 12!!) to the rearward end of seat link 122 and to the rearward end of a rear connecting link 12 4 in the same fashion that the rear support link 26 of the FIG. 1 embodiment is coupled to the corresponding seat link and connecting link.
  • a double armed control link 1126 is mounted on pivot 116 and is pivotally connected at one end by a pivot 128 to the end of rear connecting link 124, the opposite end of control link 126 being connected by a pivot 13b to one end of a foot rest control link 132, link 132 also functioning as a front connecting link to couple one end of control link 126 to the linkage which supports the front end of seat link 122.
  • a front support link 134 is mounted at its upper end on front fixed pivot 114 and is coupled at its opposite end by a pivot 13s to another front support link 133 mounted on a front portion of seat link 122 by a front seat pivot 14%.
  • front support link 138 is of L-shaped configuration and at the juncture of the two arms of the L, a second foot rest control link 142 is pivotally connected to front support link 138 by a pivot 144.
  • a foot rest link 146 is con- 'nected to the outer ends of both foot rest control links 132 and 142 by respective spaced pivots 14S and 151;.
  • the contracted position of the linkage corresponding to the position of the FIG. 1 em bodiment in PEG. 1, is now shown, but is determined as in the FIG. 1 embodiment by the engagement between seat link 122 and base link 1113.
  • the fully reclined position of the fixture is established by the engagement between a projection of pivot 114 and a portion of the upper edge of control link 1126 which may be recessed as at 152.
  • the leg rest structure may be modified as in FIGS. 7 through 9 so that the leg rest, when in its retracted position, presents a smooth upholstered appearance from the front of the cha r. This is accomplished by dividing the upholstered portions of the leg rest into a main leg rest ML and an auxiliary leg rest AL.
  • the structure of the chair seat S is somewhat modified from the FIG. 1 construction in that the seat S of the PEG. 7 through 9 embodiment is extended a greater distance forwardly from the front end of seat link 24 as by the employment of a Wider front frame member 202 on the seat frame.
  • FIGS. 7 through 9 is identical to the fixture shown and described in connection with FIGS. 1 through 4 and hence the corresponding links in the FIGS. 7 through 9 embodiments are identified by the reference numerals employed in the description of FIGS. 1 through 4.
  • the main leg rest ML is not coextensive with the length of leg rest link 50 as in the FIG. 1 embodiment, but is fixedly secured upon the leg rest link to project from that end of link 50 remote from the chair seat when the leg rest is in leg supporting relationship with the seat.
  • Auxiliary leg rest AL is mounted upon an auxiliary lcg rest support member 264 which is pivotally supported upon leg rest link 50 by pivot 56 which connects link 54 of the fixture to leg rest -3.
  • Support member 26 4- is located upon pivot 56 between link 54 and leg rest link and is formed with a pair of laterally projecting ears or stop lugs 2%, 2.68 which project from member 204 into the path of pivotal movement of link 54 relative to memher 2%.
  • Auxiliary leg rest support member 294 is frictionally gripped between link 54 and leg rest link 50 to a degree sufficient to prevent relative pivotal movement of member 29- 3 about pivot 58 in the absence of the application of some external force to member 204-.
  • member 234 When the fixture is in the normal position of FIG. 7, member 234 is maintained in the position shown in FIG. 7 by the engagement of stop lug 208 with one side of link 54 and by the engagement between a flattened side surface 210 on member 2% and a laterally projecting flange 212 on link 5%.
  • Auxiliary leg rest AL is so constructed that its front surface is aligned with, and forms a downward continuation of, the front surface of seat S.
  • link 54 Upon movement of the chair from its normal position to its semi-reclined position, link 54 is swung about pivot 56 in the manner described above and during pivotal movement of link 54 about pivot 56, link 54 engages the opposite stop lug 206 to rotate member 204 about pivot 54 to shift member 294 into the position shown in FIG. 8 when the fixture is in the intermediate position. In this position, a shoulder 7.14 on member 204 is engaged with the rearward edge of flange 212 on leg rest link 5t Movement of the fixture from the semi-reclined position to the fully reclined position shifts link 54 about pivot 56 to the position shown in FIG. 9.
  • auxiliary leg rest AL is maintained in the illustrated position by the weight of the legs of the occupant of the chair on the upper side of auxiliary leg rest AL. This maintains member 264 against movement about pivot relative to leg rest link 59 and 'maintains shoulder 214 in engagement with the rearward edge of flange 212.
  • auxiliary leg rest Upon return of the fixture to its normal position, auxiliary leg rest is rotated during the final portion of movement of the fixture into its normal position by the engagement between link 54 and stop lug 2% so that the auxiliary leg rest is relocated in the FEG. 7 position upon return of the fixture to its normal position.
