  • An upper square-prism-shaped spindle 178 of the gear 1 64 extends through the upper gear box cover 158a and is received within a correspondingly sized and shaped square hole 180 of a gear 182 received on the bridge portion 156.
  • the gear 1 64 and the gear 180 are engaged with each other for rotation about a common longitudinal axis.
  • the gear 182 is in mesh with a gear 184 on the bridge portion 156.

  • a lower square-prism-shaped spindle 188 of the gear 1 68 extends through the lower gear box cover 158b and is received within a correspondingly shaped and sized square hole 190 of the cam wheel 172.
  • the gear 1 68 is engaged with the cam wheel 172 for simultaneous rotational movement about their common longitudinal axis, and such will also bring about rotational movement of the pin 174.
  • Fig. 11 shows an enlarged exploded view of the stepped gear 166 shown in Fig. 10.
  • the stepped gear 1 66 includes a stopper 1 66a, a spring 1 66b, a pin 1 66c, an upper gear 1 66d and a lower gear 1 66e, which collectively form a clutch arrangement.

  • the assembly 100 also includes a
  • MODE CHANGE button (not shown) operable to change the mode of swivelling of the support frame 106. Activation of the MODE CHANGE button will in effect reverse the direction of rotation of the output spindle 176 of the motor 170. Turning again to Fig. 7, a reversal of the direction of rotation of the output spindle 176 of the motor 170 will cause the gear 184 to rotate in a direction opposite to that indicated by the arrow J. The gear 184 will then come in mesh with the quarter-circle rack 144 and travel relative to and along the rack 144 until it reaches the position shown in Fig. 8, where the gear 184 is again just out of mesh with the rack 144.
  • the slot 138 is parallel to the longitudinal axis B-B of the base 102
  • the body 132 of the rear support 112 will move along a path which is parallel to the longitudinal axis B-B of the base 102, thus causing the support frame 106 (and the cradle/bed or chair/seat carried by it) to swivel about the axis C-C.
  • the MODE CHANGE button may be activated again to reverse the direction of rotation of the output spindle 176 of the motor 170, so that the gear 184 rotates again in the direction indicated by the arrow J, whereupon the gear 184 comes into mesh again with the quarter-circle rack 144, travels along the rack 144, thus bringing the movement regulator 134 and movement converter 146 into simultaneous and corresponding swivelling movement about their common longitudinal axis F-F until they have travelled back by 90°, when the gear 184 is again in the position shown in Fig. 7, in which it is just out of mesh with the rack 144.
