of the basin so that a client 39 s neck may be nested into the indentation at each side of the stand 14 sub frame members 22 24 and 26 rigidly mounted to the frame 13 create a structure to which a pair of support frame members 20 are rigidly attached a pair of struts 16 and 18 are pivotally connected at one of their ends to each side of the platform 12 and pivotally connected at their other ends to the support frame member 20 at each side of the support stand frame each pair of struts 16 and 18 frame member 20 and side of platform 12 form a 4 bar linkage so that as the platform is moved between its two extreme positions shown in fig2 and 3 the platform 12 moves along a circular arc without the angular orientation of the basin relative to the stand being altered ie without the basin being tilted in fig3 the forward most position 33 of the basin is indicated by the dashed lines at the top right of the figure a spring attachment strut 28 is rigidly attached to each of the two struts 18 a coil tension spring 30 extends from the rearmost end of each strut 28 to the top end of sub frame member 24 this provides a varying degree of lift to the platform 12 which increases as the position.
