Definitions

  • Multiple position chairs are characterized by their ability to be brought to various tilted body-supporting positions with the leg-rest properly extended.
  • Typical of the multiple position type of chair is the so-called twoposition chair which has a rigid seat and back-rest unit mounted on a support frame for rearward movement through a first motion phase from a sitting position to an intermediate tilted position, and then through a second motion phase to a fully tilted position.
  • a leg-rest is also included in the chair structure and is provided with actuating means adapted to move the leg-rest from a retracted position beneath the seat to an extended, leg-supporting position forwardly of the seat in response to movement of the body-supporting unit during the first motion phase from the sitting position to the intermediate tilted position.
  • the leg-rest actuating means is adapted to maintain the leg-rest extended in proper legsupporting position.
  • the intermediate position of the body-supporting unit is a slightly-tilted active position with the occupants body in a substantially upright attitude suitable for viewing television, talking, reading or the like.
  • the leg-rest has already moved to an extended position for supporting the occupants legs.
  • the body-supporting unit can then, When desired, be tilted further to an inactive fully-tilted position in which the occupants body is supported in a more supine or recumbent position for greater relaxation, and with the leg-rest still extended in position to support the outstretched legs of the chair occupant. 7
  • An object of the present invention is the provision of novel and improved control means for multiple-position reclining chairs in which a single carrier member and a front guide link are employed at the forward end of the seat for providing the two-position movement.
  • Another object of the invention is the provision of control means for multiple-position chairs which produces an effective and eflicient two-position movement wherein the center of rotation of the body-supporting unit shifts from a pair of guide links providing a compound movement, to a single pivot at the rear of the chair providing a simple pivoting movement.
  • a further object of the present invention is the provision of improved leg-rest control means adapted to automatically adjust the level to which the leg-rest is brought, so that in the final movement of the unit to the fuily-tilted position, the leg-rest is lowered from a maximum height to a proper leg-supporting level relative to the forward end of the seat.
  • a body-supporting unit mounted on two guide links for rearward movement to an intermediate tilted position.
  • the front guide link is mounted on a carrier link, the forward end of which is pivotally mounted on the support frame, so that when the rear guide link is blocked at the intermediate tilted position, the carrier link is raised about its pivotal mount by the front guide link, permitting the body-supporting unit to turn about its pivotal connection with the blocked rear guide link.
  • a control link is provided to raise the leg-rest to an extended 2 position, the control link having a sliding engagement with the carrier link so as to provide the downward compensating movement of the leg-rest in the final stages of movement of the body-supporting unit.
  • FIG. 1 is a side elevational view, with parts broken away and shown in section, of a reclining chair incorporating control means made in accordance with theinveution, the chair being shown in an upright sitting position, and the le'grest thereof being shown in a retracted position;
  • FIG. 2 is a side elevational view similar to FIG. 1, but showing the chair in its intermediate tilted position with the leg-rest extendedto a leg-supporting position;
  • FIG. 3 is a similar side elevational view showing the chair parts in a transitory position between the intermediate and fully-tilted positions;
  • FIG. 4 is a similar side elevational view showing the chair in its fully-tilted position.
  • the reclining chair shown therein comprises a base or support frame designated generally by the reference numeral 10 and having spaced side walls 12 interconnected by cross bars or braces 14 and 16.
  • the chair also includes a bodysupporting unit designated generally by the reference numeral 18 and comprising a seat 20 and a back-rest 22 formed rigidly with-each other.
  • the body-supporting unit 18 is movably mounted on the support frame 10 for movement relative thereto from the upright sitting position of FIG. 1 to the active intermediate tilted position of FIG. 2, and then t-oan inactive fully-tilted position shown in FIG. 4.
  • the mounting of the bodysupporting unit 18 on the support frame 10 is accomplished by a pair of guide links 24 and 26.
  • the chair also includes a carrier member or support bar 30, the forward end of .which is mounted by a pivot 32 on the support frame 10.
  • the rear end of said carrier member 30 is connected by pivot 34 to the lower end of the front guide link 24.
  • the upper end of the front guide link 24 is connected by pivot 36 to the seat 20.
  • the rear guide link 26 is mounted at its lower end on the support frame 10 by pivot 38, and at its upper end is connected by pivot 40 to the rear portion of the seat 20.
  • the seat rests upon and is supported by the cross bar 16.
  • the carrier member 30 is in a substantially horizontal position, resting upon the front cross bar 14.
  • the chair also includes a leg-rest 46 which has a rigidly-connected extension bar 48 mounted by pivot 50 on the front end portion of the seat 20, forwardly of the pivot 36.
  • a leg-rest control link 52 is connected by pivot 54 to the leg-rest extension bar 48 at a point spaced beneath the pivotal mount 50 of said extension bar.
  • the lower end of said control link 52 carries a pin 56 which extends into a longitudinal slot 58 in the carrier member 30.
  • the carrier member 30 rests upon the front cross bar 14, the latter preventing said carrier member 30 from pivoting downwardly.
  • the rear guide link 26 is in an upright position and the front guide link 24 is forwardly inclined.
  • the leg-rest 46 is in a retracted vertical position extending downwardly beneath the forward end of the seat 20.
  • the pin 56 carried by the control link 52, is located at the rear of slot 58.
  • the carrier member 30 remains stationary, resting upon the cross bar 14, and thus in effect serves as a fixed portion of the support frame '
  • the pivotal mount 34 of the front'guide link 24 is therefore a fixed pivot, during this first motion phase, for the rearward turning movement of said front guide link 24.
  • the intermediate tilted'position of FIG. 2 is determined by engagement of the rear guide link 26 with a stop member 60 immovably mounted on the support frame 10, the stop member 60 preventing further rearward turning movement of the guide links 24 and 26 relative to the support frame.
  • leg-rest 46 therefore, turns around the fixed pivot 54 and is raised to'its extended position of FIG. 2, wherein it is positioned to support the legs of the chair occupant.
  • the body-supporting unit 18 is only slightly tilted and the occupants body is supported in a substantially upright attitude suitable for reading, viewing television, or the like.
  • the leg-rest 46 is sufiiciently extended to properly support the outstretched legs of the occupant.
  • FIG. 3 This position of FIG. 3 is merely a transitory position between the intermediate and fully-tilted position, and is included herein to show the movement of the linkage parts during the second motion phase.
  • the leg-rest 46 during the second motion phase, is first raised to a maximum level relative to the seat and then lowered slightly, so that in the fully-tilted position of FIG. '4 it is positioned to comfortably support'the legs of the occupant.
  • the points marked A, A, A and A in FIG. 4 indicate the travel of the pin 55 during the rearward movement.
  • the point A is the position of pin 56 in FIGS. 1 and 2, the point A the position of pin 56 in the transitory position of FIG. 3, the point A the location of pin 56 in a further transitory position, and the point A the final position of said pin in the fully-tilted position of FIG. 4.
