Definitions

  • the invention relates to multipart a rotary adjustment knob assembly utilized in cooking devices, particularly in ovens.
  • Domestic ovens generally have a front panel attached to upper side of the body defining a cooking chamber.
  • Front panel is equipped with a control panel or adjustment knobs to set operation parameters. Temperature of the ovens with simple control assembly is adjusted by means of a mechanical thermostat, and the operation configuration of the electric heating elements are performed by a program switch, particularly a mechanic switch. Both thermostat and switch are controlled via shafts extending vertically towards the front panel. Knobs on the front panel are passed through the shafts, allowing the user to adjust the oven function and temperature separately by turning each knob.
  • Rotary knobs comprise an elongated sleeve engaging the shaft and an outer ring to which the sleeve is mounted at a proximal end and adapted to the front thereof to facilitate gripping.
  • TR200501576U discloses a coupling element comprising at least one tab element, which connects the knob body, mounted inside a mounting hole of a display show the previously adjusted settings and with having a channel to be fixed on the channel and/or the hole to prevent retraction of the channel and inside the mounting hole to immobilize the display.
  • the invention comprises a central core member and a support body secured from a proximal edge to the front portion of the core member and radially surrounding the core member to form a coaxial tube structure.
  • Rotary adjustment knob also comprises an outer ring at least partially disposed at the outer periphery of the support body from an inner portion, an axial groove and a guiding post reciprocally engaged between the inner portion and the outer periphery in a radially interlocking manner.
  • Outer ring allows the rotation of the adjustment knob by the user by grabbing. Meanwhile, the axial groove and the guiding post engage each other, preventing the outer ring from sliding on the outer periphery of the support body.
  • the guiding post extends, for example, in the form of a line so as to fill the entire axial groove.
  • the guiding post can partially fill the axial groove, for example in the form of a point.
  • Axial groove can be parallel with the rotation axis directly, or can be configurated in the form of an inclined or curvilinear groove comprising an axial component.
  • a preferred embodiment of the invention a radial groove and corresponding protrusion provided between the inner portion and the outer periphery and engage each other in an axial locking manner on the outer ring on the support body.
  • Radial groove aggravates the removal of the outer ring from the outer periphery of the support body by pulling the outer ring in the axial direction.
  • the radial groove is provided on the outer periphery of the support body, and the corresponding protrusion is provided on the inner portion of the outer ring.
  • Outer ring can be stretched more than the support body due to its wider diameter, allowing the protrusion to be on the inner portion of the outer ring, facililates the assembly thereof.
  • outer periphery comprises the outer periphery is having a radially outwardly extending rear portion stepped at its rear end, and the outer ring is arranged circumferentially along a rear edge to fit into the rear portion step. This particularly facilitate the mounting of the outer ring to support body by front-pushing.
  • Inner diameter of the outer ring is preferably smaller than the rear portion provided with notch, allowing the reclining of the ring by pushing.
  • the guiding post and radial groove are provided adjacent to the rear portion of the outer periphery with a certain distance between each another. Therefore, the outer ring can be mounted to the support body from its rear edge with a close proximity to the notched portion. Therefore, the radial groove is fully seated on the axial groove guiding post and passes through the rear edge, allowing a safe fixing thereof.
  • the guiding post and radial groove extend perpendicular to each other.
  • the guiding post directly resists radial and axial stresses with the radial groove.
  • the core member is in the form of an elongated tube-like structure that completely surrounds the outer periphery of the supporting body coaxially with the outer ring. In this way, by rotating the outer ring, maximum torque transmission can be transferred to a gas adjustment valve or switch shaft that can be mounted from the rear end of the core member or to a pop-out mechanism mounted on.
  • the invention comprises a retaining extension extending inwardly from the front of the support body and engaging a corresponding hole in the proximal edge of a core member arranged abutting the front wall.
  • a retaining extension extending inwardly from the front of the support body and engaging a corresponding hole in the proximal edge of a core member arranged abutting the front wall.
  • Retaining extension supports the core member for torque transmission.
  • retaining extension is a radially distributed multiple arm structure concentric with the core.
  • a preferred embodiment of the invention comprises a tab and a retaining slot provided opposite each other in such a way that allows the inner face of the inner sleeve and the outer part of the core member to be coupled to one another. In this way, the core member is prevented from coming out of the support body by pulling.
  • tab and the retaining slot are aligned concentrically with the radial groove. In this way, when the outer ring and the support body and the core member extend coaxially, the protrusion and radial groove in the tensile direction, as well as the tab and the retainer slot, form resistance against.
  • the outer ring comprises a front wall mounted to hold a cover that extends and leans over the front portion of the support body.
  • the front wall both protects the front portion of the support body and can be in different colors for decorative use as a separate piece.
  • the support body and the outer ring are made of plastic material. This allows the stretch of the flexible plastic outer ring in the distance of the guiding post when the axial groove and the corresponding guiding posts engage each other when threaded onto the body.
  • Figure 1 is a disassembled perspective view on the same axis of a representative application of the rotary adjustment knob in the pop-out structure.
  • Figure 2 is a rear perspective view of the core member in a representative embodiment of the rotary adjustment knob according to the invention before its assembly into the support body.
  • Figure 3 is a perspective view of a representative embodiment of the rotary knob mounted on the shaft.
  • Figure 4 is an inner perspective view of an outer ring on the rotary adjustment knob shown in Figure 1.
  • Figure 5 is the front perspective view of the support body that is adjusted to fit the outer ring shown in the Figure 4.
  • Figure 6 is the cross-sectional view of a representative embodiment of the rotary adjustment knob according to the invention in the assembly stage.
  • a flat lower extension (43) is located below the outer portion (42) towards the proximal edge (41 ).
  • a support body (30) in the form of a cylindrical cover positioned against the core member (40) from a circular inlet portion (36) so as to grip the core member (40).
