  • Figs. 3 and 4 differ in that in the case of Fig. 3 the heating element body is of lesser diameter, e.g. a standardised 140 mm diameter, in which case the fastener, i.e. rivet 15 passes through the slot 13 of the support base 11 of the support bracket at that end of the elongate slot 13 which is closest to the bending line connecting the base member 1 1 to the support arm 8'.
  • a heating element body of larger diameter e.g. a standard 180 mm element body is accommodated, and in this case the fastener 15 is positioned in the slot 13 at the far end of the slot 13 closest to the centre where the screw 9 is fitted.
  • Fig. 3 the support base 7 (instead of being fitted to the bottom of a table top appliance as in Fig. 1) is secured by a screw 10 onto a horizontal bracket 102 spanning a gap between opposite ends (not shown) of a cooking range and extending centrally across the underside of the mounting system.
  • the spring properties of the resilient support brackets are indicated in Figs. 3 and 4 by showing the relaxed position of the shoulder 12 and of the support arm in dashed lines, whereas the depressed and spring-loaded position occupied in the fully completed and assembled state with the element body in place and pressed against the vitreous ceramic top is shown in solid lines.
  • the support base 7 includes an elongate aperture 7A for the passage therethrough of a bolt 16" which is fastened by means of a nut 16A".
  • the support base 7 comprises lugs 19 serving as guide formations for the lateral containment of the support bracket 8".
  • Fig. 6 shows yet a further modification of the resilient support bracket wherein the radially extending base portion 11' is again radially outwardly directed in respect of the centrally positioned screw 9 and the resilient support arm 8'" is connected by a U-bend 23 to that end of the base portion 11' which is closest to the centre region represented by screw 9.
