Definitions

  • the type of chair to which the present invention relates is one having a back and seat movable from an upright sitting position to a 'reclining position, and a leg rest movable from a retracted position to an extended position where it supports the userls legs.
  • the chair back is adapted to swing downwardly and rearwardly and the seat shif'ts upwardly and forwardly from a normal, sitting position to a more comfortable, reclining position.
  • the leg rest is independently movable from a retracted, inactive position beneath t-he chair seat to an upward and forwardly extended position where it elevatingly support-s the users legs in either the sitting or reclining position.
  • This invention relates generally to lounge chairs, and particularly to an improved reclining chair having an extendable leg rest.
  • the retracted leg rest and the linkage mechanism movably su'pporting the leg rest are concealed by chair frame side panels which reach substantially to the floor.
  • some modern decorating sc-hemes make it desirable that the chair be styled of-the-floor or, in other words, that the chair embody exposed legs supporting the chair frame up otf the floor.
  • the latter chairs do not have deep side panels so that a conventional linkage mech'an-ism would present an unsightly appearance in that t'hey would be largely exposed for view below the bottom of the frame.
  • the leg rest in these previous chairs retracts only to a substantially Vertical position benea'th the front portion of the chair seat.
  • the chair of the present invention provides a clean styling and pleasant appearance and is relatively easy to manipulate so that even when these chairs are fully reclined, the occupant can shift the chair seat and back to the sitting position without exerting a great deal of force.
  • the leg rest linkage and back and seat mechanism are substantially concealed when said leg rest is re-tracted and the overall chair appearance is clean and aesthetically pleasing.
  • the reclining back and forwardly movable seat is smooth in operation, easy to manipulate in any position, is light in weight, is rugged in construction and relatvely inexpensive to manufacture.

  • the linkages 95, 97 be concealed within the chair base 23 and not hang therebelow sufficiently where they can be seen.
  • the leg rest linkages 95, 97 are supported by the seat 41 through the brackets 89 instead of by the chair base frame as is common in the prior art. This elevates location of the entire llinkages 95, 97 within the base frame 23 so that they then protrude only slightly below the frame 23 and are not visible to anyone either sitting or standing in a room in which the chair is located.
