Definitions

  • the invention relates to improvements in and relating to chairs and more particularly to improvements in and relating to elevator chairs particularly reclining elevator chairs having a tiltable back portion, an extendable leg rest portion and actuating means for raising the seat and simultaneously tilting it forwardly to assist a user in rising from the chair.
  • Chairs of this type generally have ground engaging legs which, although essential for fixing the chair in position for safety, particularly when the user is rising from the chair, mean that the chair cannot be readily adjusted in position.
  • This invention is directed towards providing a support frame for an elevator chair which will overcome this difficulty.
  • the invention relates to a support frame for an elevator chair of the type comprising a back portion, a seat portion, and an actuating means for raising and/or tilting the seat portion forwardly to assist a user in rising from the chair, the support frame comprising a base frame, side supports on which at least the seat portion of the chair can be supported, and a linkage extending between the base frame and the side supports to raise the side supports and hence the seat portion on operation of the actuating means, the support frame having castors on which the chair is supported in a lowered position.
  • DE-A-2716821 describes a chair in which a chair seat frame carries castors and the chair and seat frame are raised from a base support when the chair is raised.
  • the invention is characterised in that the castors comprise a first pair of castors mounted at one end of the base frame and a second pair of castors at the opposite end mounted to the linkage or side supports so that only the second pair of castors disengage from the ground as the side supports are raised on operation of the actuating means.
  • castor refers to a wheel, roller or the like element which rides relatively freely over a surface.
  • the second pair of castors are mounted on the side supports.
  • the first pair of castors are mounted to first cleats which are attached to the base frame and the second pair of castors are mounted to second cleats which are attached to the side supports.
  • the base frame comprises a pair of side rails which are interconnected by a rear cross member and an intermediate cross member, the first pair of castors being mounted at the junction between the side rails and the rear cross member.
  • the linkage comprises a pair of upper linkage arms extending between the rear of the base frame and the side supports and a pair of lower linkage arms, forward of the upper linkage arms and extending between the base frame and the side support members.
  • the second pair of castors are mounted at the forward end of the side supports and the side supports are strengthened in the region of the attachment between the side supports and the castors.
  • the side supports comprise a plate member having an inturned lip portion adjacent the forward end thereof to strengthen the support member in the region of the attachment of the castors to the support members.
  • a support frame according to the invention and indicated generally by the reference numeral 1 for an elevator chair 2 of the type comprising a back portion 3, a seat portion 4 and a leg rest portion 5.
  • Actuating means are provided for raising and tilting the seat portion 4 forwardly to assist a user in rising from the chair.
  • the actuating means is provided by a ram 6 operated by an electric motor 7 in response to user input from a push button control unit (not shown).
  • the support frame comprises a ground engaging base frame formed from a pair of side rails 10, 11 which are interconnected by a rear cross member 12 and an intermediate cross member 13. Forward ends of the side rails 10, 11 are turned outwardly at 14, 15 respectively, and are provided with end-caps 16, 17 to which ground engaging legs are mounted.
  • the support frame also comprises a pair of side supports, in this case provided by side support members 20, 21 having support lugs 23, 24 to which the seat portion 3 of the chair 2 is mounted.
  • a linkage extends between the base frame and the side support members 20, 21.
  • the linkage operates on actuation of the ram 6 to raise the side supports 20, 21 and hence the seat portion 3 of the chair 2 to assist a user in rising from the chair.
  • the linkage comprises a pair of upper link arms 30, 31 extending between mounting plates 32, 33 provided at the rear of the base frame and a forward end of the side support members 20, 21.
  • the upper linkage arms 30, 31 are pivotally mounted by pivot connections 34, 35, 36, 37 to the mounting plates 32, 33 and side support members 20, 21 respectively.
  • the linkage also comprises a pair of lower link arms 40, 41 which are pivotally mounted at 42, 43 to upwardly extending flanges 44, 45 provided at opposite sides of the intermediate cross member 13 and are pivotally mounted by pivot connections 46, 47 to the respective side support members 20, 21.
  • Reinforcing cross members 48, 49 extend between the lower linkage arms 40, 41.
  • a pair of rear castors 50, 51 are mounted to cleats 52, 53 respectively which in turn are mounted to the mounting plates 32, 33 at the rear of the base frame.
  • a pair of forward castors 60, 61 are mounted on cleats 62 which in turn are mounted to the side support plate members 20, 21 adjacent the forward end thereof, in use.
  • the side support members 20, 21 are reinforced in the region of the mounting of the cleats 62 by providing an inturned lip portion 65 at the forward end of the plate members 20, 21, in use.
  • the invention provides an improved support frame which allows an elevator chair to be manoeuvred safely while also allowing a user to exit from the chair safely, without any risk of the chair moving as the seat portion is being raised to assist a user in rising from the chair.
