Definitions

  • the present invention is related to a retractable rotary control knob used in all kinds of electrical household appliances, which protrudes from the control surface when pushed and which may be used for the operation of the components that are commanded by a turning or push-pull rod.
  • the knob is flush fitted to the control panel, i.e. it does not protrude from the surface in the system for aesthetic purposes as well as to prevent usage by children. In work position it projects from the panel level towards the direction wherein it is to be used and operates the component to which it is connected at the back of the panel by means of the turning rod.
  • the turning knob disclosed in the European Patent Application, No EP 9311 0933 describing a control knob according to the preamble of claim 1, consists of a push-pull type control mechanism or knob, an end piece to be connected with the said panel and another part to operate with the control device by being torsioned.
  • This part co-operates with the control element and the said end piece is connected with a body (1) that is axially movable along said part against the action of a spring and coperating torsionally therewith.
  • the part cooperating with the control element is arranged movable relative to the longitudinal axis of the knob, within a cavity in the end part of the knob; there being provided with axial retention means preventing said member from escaping off the cavity while enabling it to undergo said movement.
  • the rotary knob mounted on the external face of a household appliance is integral with an axially slidable control shaft which is moved so that a linkage is provided within a seat.
  • a drive mechanism regulating the sliding motion and stopping of the shaft is provided between the housing and the control shaft.
  • a mark-bearer on which certain characteristics are marked and which slides and rotates and is at the first protruding work (ON) position and the second rest (OFF) position together with the shaft is provided.
  • the mechanism that enables the knob to protrude from the control panel surface consists of at least four parts one of which is spring. These knobs are formed by a part providing the connection between the component being controlled by making a rotary movement through a cavity or pin connection; on this part, a housing (cavity) having a similar mechanism as that of a ball-point pen; the knob cap by which the users give rotary motion to the knob; and a spring between the cap and the part connected to the component, pushing the knob cover towards the intended direction of usage by means of a metal pin that can move inside the cavity of ball point pen.
  • the object of the invention is to realize a control knob by which the intended function is provided by using less components as compared to other similar knob mechanisms and that protrudes outwards the control panel surface enough to enable easy-holding of the knob when pushed and that controls the component to which it is connected on the panel.
  • Figure 1 is the axonometric view of the control knob in the protrubed i.e. working position.
  • Figure 2 is the axonometric view of the control knob at the control panel level, i.e. rest position.
  • Figure 3 is the section of the control knob at the control panel level.
  • Figure 4 is the section of the control knob as protrubed from the panel, ready to be controlled position.
  • Figure 5 is the section of the control knob as protrubed from the panel showing the locking mechanism.
  • Figure 6 is the section of the control knob at the control panel level showing the locking mechanism.
  • the control knob according to the invention consists of three parts, namely a knob cap (1) a knob housing part (2) and a spring (3) enabling the mechanism to move.
  • the shape of knob housing (2) enables a part of it to operate as a component coupling pin (2a).
  • the control knob is connected to the component that it controls by being inserted in it by means of this pin (2a) or by being wound around a pim of the component. When it is on the same level as the control panel surface i.e. at rest position, it is pushed forward in the direction of its rotary axis in order to bring it to a position ready to be controlled by causing it to project from the control panel.
  • the knob cap (1) has a housing on the knob housing part (2) connected to the rotor axis of the component, that enables it to slide along the same axis thus providing its forward and backward movement.
  • the internal structure of the section on the surface of the control panel level (4) of this housing may be in any geometric shape that enables the cap to transmit the rotary movement to the knob housing part (2) including the heart shaped mechanism movement space on one side and the knob cap.
  • This spring applies a constant pressure on the knob cap (1) so that the latter protrudes from the control panel surface (4).
  • a reduction in the number of parts is provided by producing and using the pin (1b) as monobloc with the plastic structure used for the cap whereas it is used as a separate element in similar applications.
  • This cylindrical pin (1b) is connected to the knob-cap (1) by means of its section in the form of a thin rib (1a).
  • This section also has such structural characteristics as flexibility in a degree to enable it to complete its (1b) cycle inside the mechanism movement space (2b) as well as rigidity in a degree to enable it to withstand this motion repeated constantly without breaking.
  • the cylindrical pin (1b) at the end of the thin rib (1a) moves within the mechanism movement space (2b).
  • the humps and obstructions (2d) formed in this space prevents the reversal motion of the cylindrical pin (1b) and provides a one-directional movement.
  • Restraining lugs (2c) are used at the plain surface where the movement space (2b) is and at the end point of the opposing surface in order to prevent the escape of the cylindrical pin (1b) from the housing (2b) by the pushing force of the spring and to provide the positioning of the knob-cap. (1) properly when it protrudes from the control panel surface.
  • Restraining lugs (2c) are used at the plain surface where the movement space (2b) is and at the end point of the opposing surface in order to prevent the escape of the cylindrical pin (1b) from the housing (2b) by the pushing force of the spring and to provide the positioning of the knob-cap. (1) properly when it protrudes from the control panel surface.
  • notches that do not obstruct the axial or rotary movement may also be used.
