Definitions

  • This invention relates to an apparatus for use in the design of orthopaedic chairs.
  • a measuring apparatus which, inter alia, may be used in the determination of the contour of a patient's back so that the curvature and posture of the back may be determined quickly and easily.
  • the invention therefore provides an apparatus for use in the design of orthopaedic chairs, the apparatus comprising a chair and a contour measuring device positioned at the rear of the chair, the contour measuring device including a first elongate member having a plurality of rods slidably mounted relative thereto, the rods being arranged in parallel side-by-side relationship along the length of the member in a substantially common plane whereby, in use, each rod is slidable so as to enable the tip of one end of each rod to engage the back of a patient sitting on the chair which tips thereby define a contour of the patient's back.
  • the device according to the invention enables a craftsman to fashion a chair according to the exact requirements of the patient using contour information derived from the apparatus.
  • the apparatus may be used in the design of chairs not primarily for orthopaedic use, for example chairs which are "personalised" to the shape and posture of the user's body.
  • an apparatus 1 which comprises a chair, generally shown as 2, and a contour measuring device generally shown as 2a.
  • the chair 2 has a seat 6 which is telescopically mounted on a support member 3 which is, further mounted on legs 4 having castors 5.
  • a conventional seat height-adjustment means having a lock-nut 4a is provided for retaining the seat at a desired height relative to the ground, the telescopic components of the support member 3 being calibrated so that the height of the seat may be recorded.
  • Attached to the seat 6 is a generally U-shaped frame 7 having a substantially square cross-section.
  • the contour measuring device 2a comprises an upright elongate member 8 mounted at the rear of the chair and having a plurality of holes therein along its length into each one of which holes is slidably mounted a respective rod 9.
  • Each of the rods 9 is calibrated and may be set relative to a datum mark (not shown) on the member 8.
  • the rods 9 are mounted in parallel side-by-side relationship and lie in a substantially common vertical plane so as to be slidable longitudinally either towards or away from the rear of the chair 2.
  • a plurality of screws 9a is also provided (one for each rod 9) on the member 8 which screws 9a releasably lock each rod 9 in the member 8 at any selected position.
  • the member 8 of the contour measuring device 2a is fixed fast to a base 2b which base 2b is slidably mounted on the frame 7.
  • the chair 2 also has a pair of parallel back members 10a pivotally mounted on the U-shaped frame 7 at opposite sides of the rear of the frame, the rake of the member 10a being adjustable by means of a conventional lock-nut 11.
  • the lock-nut 11 is calibrated so that the rake of the members 10a may be recorded relative to a datum point.
  • Joining the members 10a is a webbing 12 which, together with the members 10a, forms the back 10 of the chair.
  • the webbing 12 assumes the contour of the back of a patient 13 sitting on the chair 2.
  • the seat 6 of the chair 2 is adjustable for tilt by a conventional tilting means (not shown) located beneath the seat 6, the tilting means being calibrated so that the angle of tilt of the seat 6 may be recorded.
  • a conventional tilting means (not shown) located beneath the seat 6, the tilting means being calibrated so that the angle of tilt of the seat 6 may be recorded.
  • Attached to each leg of the U-shaped frame 7 is a respective lug 13 each having a slidable member 14 therein.
  • Each slidable member 14 carries an arm rest 15 at its upper end.
  • the height of each arm rest 15 may be adjusted relative to the seat 6 by passing a bolt (not shown) through a hole 13a in each lug 13 which bolt engages with one of a plurality of calibration holes 14a in the member 14.
  • the angle of tilt of the arm rest 15 may also be adjusted by means (now shown) which is calibrated as regards the angle of tilt.
  • the screws 9a are loosened so as to permit all of the rods 9 to slide longitudinally relative to the upright member 8.
  • the patient 13 is now asked to sit comfortably and upright in the chair 2.
  • the seat 6 is adjusted to a comfortable height by means of the knob 4a; the tilt of the seat is adjusted; the rake of the back 10 is adjusted by means of the lock-nut 11; and the height of each arm rest 15 is set on instructions from the patient 13.
  • their relative positions may be recorded.
  • the patient's back rests against the webbing 12 which assumes the contour of the patient's back.
  • the rods 9 are in a sufficiently rearward position in the member 8 not to engage with the patient's back.
  • the member 8 When the patient 13 is comfortable, the member 8 is pushed along the rear of the U-shaped frame 7 so as to be on the extreme left of the frame 7 as viewed in Fig. 3.
  • the rods 9 are pushed in the member 8 in a forward direction towards, the patient's back until the forward tip of each rod 9 rests lightly on the patient's back or the webbing 12 as the case may be. A vertical contour of the patient's back at that location is thus taken, the calibration on each rod 9 is recorded, and the position of the member 8 relative to the frame 7 is also recorded.
  • Each of the rods 9 is now pulled rearwardly and the member 8 is slid to the right as viewed in Fig.
  • the patient 13 may then leave and the measurements given to a craftsman who translates the measurements into a chair which is shaped and contoured in a manner particular to the patient 13.
  • the screws 9a may be used to lock each rod 9 in position so that when the patient 13 leaves the device 1, the sheet may be placed along the contour thus generated and the contour may be then drawn onto the sheet for subsequent use by the craftsman.
  • the upright member 8 has vertically slidably mounted thereon a horizontal second elongate member 80 which is similar to the member 8 except that its base 22b is located centrally thereof.
  • the upright member 8 has a U-section to permit the base 22b of the horizontal member 80 to slide vertically therein.
  • the sliding action of the base 22b in the U-section should require a positive push. In other words, in the absence of a force being applied to the member 80, the latter should remain in a fixed position on the member 8.
  • the rods 9 of the upright member 8 should be pulled rearwardly to permit the member 80 to slide freely on the member 8.
  • the base 2b of the member 8 should be located centrally on the frame 7 when the member 80 is in use.
  • the slidable rods 9 of the horizontal member 80 function in a similar manner to the rods 9 of the member 8, except that in this case they are mounted in parallel side-by-side relationship along the length of the member 80 in a substantially common horizontal plane. If desired, screws may be provided to releasably lock each rod 9 in the member 80.
