Definitions

  • a further object of the invention is to provide armrest mechanism which can be disconnected for lowering the back for shipping, and easily reconnected for chair installation.
  • Fig. 3 is a left side elevational view, enlarged, of a portion of the chair of Fig. 1 with the cover out of position to illustrate the armrest mechanism in condition for shipping;
  • Fig. 4 is a top perspective view of the armrest mechanism of the invention with the cover out of position, illustrating its condition when the back is in an upright position;
  • Fig. 5 is a view similar to Fig. 4, with the cover removed to show the link portion of the mechanism of the invention;
  • Fig. 8 is a view in perspective of a trigger and spring which are part of the armrest mechanism;
  • Fig. 9 is a bottom perspective view of the mechanism of Fig. 4 •
  • the link 39 as shown in Fig. 3, may have the shoulder bolt 42 removed, whereby the armrests supports 31 and armrests 14 are free to move to the position shown in Fig. 2 for shipping.
  • the link 39 is provided with a relief 45, as shown in Fig. 5, for clearance to allow folding of seat back 12 for shipping or other purposes .
  • the chair 10 may also be provided with removable covers 46, 47, and 48, and which normally conceal plates 36 and 12.
  • the boss 66 has a locking lug 67 extending therefrom, which is urged toward slide 20 by spring 63, which slide has cut-outs 68 and 69 therein for lug 67 engagement to lock the armrest 14 in forward or rear position.
  • the seat back 12 includes a cushion 70 which is filled with a resilient support material of well-known type, and covered with a layer of vinyl 71.
  • the cushion 70 is designed so that it is wider than the shoulders of the largest person (not shown) who is expected to occupy the chair. Accordingly, the patient's upper arms (not shown) engage the cushion 70 for all expected positions of the back 12, and the armrests 14 support the patient's lower arms in the same position relative to the seat back 12, and urge the upper arms toward the back cushion 70.
  • the trigger handles 65 are engaged to rotate against locking springs 63 to urge the lugs 67 out of engagement with cutouts 68, so that armrests 14 can be slid along armrest supports 31 until cutouts 69 are engaged by the lugs 67, and the armrests 14 are in the rearmost position so that the patient can enter or exit the chair without interference from the armrests.
  • the armrests 14 can be slid back to the front position to support the patient's lower arms when in the chair.
  • its mechanism (not shown) is actuated and its position changed. The pivoting of seat back 12 about bolts 35 causes links 39 to move armrest supports 31 whereby the armrests 14 track the movement of seat back 12.
