Definitions

  • This invention relates to control knobs.
  • knobs are advantageous in that they give the appliance a streamlined look, they are difficult to inadvertently turn ON and they tend to be, to some extent, childproof.
  • a control knob comprising a pair of laterally disposed flap members which are pivoted relative to one another and which are spring biassed so that they normally lie substantially in the same plane, the flap members being rotatable against the spring bias to afford a finger grip portion by means of which the control knob may be operated.
  • the flap members may be rotated to afford the finger grip portion, or they may be rotated to afford access to a finger grip portion.
  • the control knob depicted in Fig. 1 of the drawings comprises a hollow, generally hemispherical body 1, into the opening of which is designed to fit a pair of laterally disposed semi-circular shaped flap members 2.
  • the flap members 2 are provided over approximately half the length of their straight edge with an inward flange 3 in which is a through bore 4 which is aligned with the straight edge.
  • the two flap members 2 are assembled together by means of a pivot pin 5 which extends through the bores 4 in the flap members 2 and which also engages diametrically opposed holes 6 in the body 1.
  • the body 1 may be provided with grooves 6a, as shown in the detail drawing of Fig. 1a, into which the pivot pin 5 may be snapped.
  • a spring 7 which is contained in an enlarged area 8 of the through bore 4, the spring 7 having the effect of biassing the flap members 2 outwards so that they are substantially flush with the outside rim of the body 1.
  • Fig. 2 of the drawings the control knob of Fig. 1 is shown assembled on the spindle 9 of a control device 10 which may, for example, be an energy regulator of an electric cooker, or a gas tap of a gas cooker.
  • the control device 10 may, of course, take any convenient form.
  • the knob is fitted behind a suitable hole 11 in a fascia panel 12 so that the front surface of the knob is substantially flush with the fascia panel 12.
  • the spindle 9 of the control device 10 is conveniently of 'D' shaped cross-section and engages with a corresponding shaped hole 13 in the body 1, an inner boss 14 being formed in the body 1 into which the hole 13 extends.
  • Operation of the control knob is effected by causing the flap members 2 to be pushed rotatively inwards towards each other, using a finger and thumb, against the bias of the spring 7, whereby the flap members 2 form a finger grip portion which may be gripped to effect rotation of the spindle 9 of the control device 10.
  • the flap members 2 assume their normal 'flush' position under the action of the spring 7.
  • the flap members 2 may be made completely flush with the outer surface of the fascia panel 12 by providing that the outer rims of the flap members 2 are recessed to take account of the thickness of the fascia panel 12.
  • control knob is used to effect rotation of the spindle 9 of a control device 10, it is envisaged that it may also be used in conjunction with a linear (slide)-control device.
  • the shape of the flap members 2 may be of any convenient form depending upon the particular application.
  • the flap members 2 are conveniently of semi-circular shape, whereas for linear operation they may be of square or rectangular shape.
  • a rotary control knob with information indicative of its rotary position
  • Figs. 5 and 6 of the drawings there is shown the control knob of Fig. 1 provided with a cylindrical skirt 15 which is formed integrally with the body 1 and on which is provided numerical information 16.
  • Figs. 7 and 8 the control knob of Fig. 1 is shown provided with a radially disposed skirt 17 which is formed integrally with the body 1 and flush with the flaps 2 and on which is provided numerical information 18.
  • the information carrying skirts 15 and 17 are shown as being formed integrally with the body 1 of the control knob, it will be appreciated that they could be separate from the body 1 and attachable to it. It will also be appreciated that the information provided on the skirts 15 and 17 may take any form.
  • Fig. 9 of the drawings there is shown an alternative form of construction of the control knob of F ig. 1, in which the body 1 thereof is provided with an internal, diametrically formed bar 19, the top 20 of which is provided with integrally formed 'living hinges' 21 which connect the flaps 2 to the bar 19, thereby dispensing with the spindle 9 and spring 7 of the control knob of Fig. 1.
  • the operation of the control knob of Fig. 9 is identical to that of Fig. 1.
  • FIGs. 10 to 12 of the accompanying drawings there is shown an alternative form of construction of the control knob of Fig. 1 in which the flaps 2, instead of being pivoted along their straight edges are provided with tangentially disposed outer pivots 23 which, when the flaps 2 are deflected inwards permits access to a diametrically disposed central bar 24 which forms a finger grip for the control knob.
  • the flaps 2 are provided with a tangentially disposed flange 25 having a through bore 26 in which locates a pivot pin 27 which slots into grooves 28 in the body 1 of the control knob.
  • they are each provided with an angled leaf-spring element 29 a lower part 30 of which slides into opposed slots 32 in the body 1 of the control knob, and an upper part 31 of which locates under the respective flap 2 to bias it in the 'flush' position but which enables it to be deflected inwards as required to provide access to the finger grip bar 24.
  • control knob may be mounted on a control spindle 9 and may be located in a hole in a fascia plate 12.
