Definitions

  • the invention relates to a multi-part handle adapted to a hinged door for an oven.
  • a hinged door on the oven covers an opening leading to the cooking chamber.
  • a handle with a grip part extending lengthwise is fixed onto the outer panel.
  • the gripping part is typically in an extended profile structure to ensure easy grasp.
  • a connection part is used to mount the grip part onto a glass outer panel of the door.
  • the connection part is mounted to the grip part on one side and screwed onto the panel on the other.
  • the opening is covered with a cover.
  • the connecting element and the cover are mounted onto the profile with the help of screws and rivets.
  • EP1965681 B1 relates to a household appliance with a handle where a flat surface is provided at the end of the gripping part, allowing the cover to slide into the grip part and be easily removed. The cover is prevented from coming out of the gripping part.
  • the cover also includes a locking lever extending into the grip part from the head part when the cover is inserted into the socket and a locking pin located at the end part.
  • the locking lever includes a locking socket into which the locking pin is inserted into the socket. The position of the lock socket and the length of the lock lever have been selected to ensure that the locking pin sits in the lock socket when it leans against the extension rod.
  • the object of the invention is to facilitate the assembly of the profile cover to an oven handle with a profile structure gripping extension.
  • the invention is related to a handle for an oven door, comprising a gripping part from an extended hollow profile having mutually free ends.
  • the handle further comprises a flat cap has a plug completely covers the lateral part at the outer periphery of the free end of the gripping part in the assembly position, and the plug has a flexible tab that extends directly from the inner wall of the plug and inserts into a corresponding slot provided in the inner part close to a free end of the gripping part in the assembly position.
  • the flat cap hermetically seals the profile cavity by abutting the outer periphery of the handle. Since the tab extends directly from the inner wall, it easily passes through the inner wall to the slot it reaches when the cap abuts the outer periphery.
  • the cover is the cap made of plastic injection molded in one piece. In this way, a flexible tab extending from the cap is also inherently formed in the cover, which is easily produced with a single molding operation.
  • a ring radially extends and leans against the inner wall from the inner wall of the cap.
  • the ring ensures axial alignment during assembly by passing from the free end to the inner wall as the cover is pushed end-to-end onto the gripping part in the assembly position.
  • the ring can be formed in a closed geometry or, alternatively, in a segmented or open geometry from one end.
  • a filled area extends axially along the gripping part's inner surface and forms an open periphery that rests on the filled area from the ends of the ring.
  • the filled area both increases the structural resistance of the gripping part against bending and creates the necessary thickness for opening a functional slot or hole on the profile.
  • the filling forms a D-like form with the profile section shape, for example, having a circular section.
  • the tab is set perpendicular to the plug at the open periphery of the ring. This way, a compact cover is obtained. In the cover guided to the inner wall in the gripping part with the ring, the tab can flex towards the inner part of the ring during assembly and reach the inner wall to pass through the slot.
  • the tab's extension axis is set at a distance from the center axis of the ring. This way, an area has been created where the tab can flex towards the ring center axis. This allows the tab to advance against the inner wall when it is not seated in its place during assembly and disassembly.
  • the ring is set adjacent to the outer periphery of the plug. It is possible to lean the ring against the inner wall by forming a thin and flat ring. Less material is used, and the internal volume surrounded by the ring is increased.
  • the slot is in the form of a hole that opens throughout on the surface of the gripping part. In this case, a slot can be formed in the gripping part by simply drilling a hole from the outer part at the filling level. There is no need for an additional process at the inner wall.
  • a connecting part that can be adjusted to lean against a flat panel from its back wall and engages from a front wall to the rear face of the gripping part.
  • the connecting part allows the gripping part to be mounted on the front panel of an oven, such as a glass panel.
  • the gripping part is made of aluminum extrusion.
  • the gripping part is strong enough to open the oven door and can be easily produced in a hollow rod structure.
  • the connecting part is prismatic in form, narrower than the width of the gripping part, and its front wall directly adjoins the corresponding rear face.
  • the gripping part is integrated with the connecting part, and the handle has the appearance of a single piece.
  • the gripping part is in the form of a rod, and the connecting part is set at a distance as a pair, aligned with the plug at each free end of the gripping part.
  • the cover closes the inner cavity without extending the gripping part and spoiling its appearance.
  • a preferred embodiment of the invention is an oven with a handle cover suitable for any of those described above.
  • Figure 1 is a front-perspective view of a representative configuration of a handle for an oven door.
  • Figure 2 is a front partial perspective view of the handle shown in Figure 1 with the connection part and the gripping part before assembly.
  • Figure 3 is a cross-sectional view of a representative configuration of the oven handle subject to the invention.
  • Figure 4 is a rear partial view of the handle.
  • Figure 5 is an AA sectional view of the handle.
  • FIG 1 shows a representative structure of a handle for an oven door according to the invention from a front perspective.
  • the handle has a bar structure, made of hollow aluminum extrusion, referred to as the gripping part (10).
  • the two ends of the gripping part (10) form lateral sections (14) with their transverse flatly cut structure.
  • the gripping part (10) is cylindrical and has a D-like cross-section form in its transverse section with a hole passing through it. In this way, the cylindrical wall forms a radially limited filled area (16).
  • the filled area (16) forms a flat wall facing the hollow space throughout the gripping part (10) by providing a partial thickness in the hollow space of the cylindrical gripping part (10).
  • the filled area (16) is obtained through injection from the gripping part (10).
  • the gripping part (10) is obtained by pulling with an injection mold that ensures the internal hole to be D-shaped.
  • the semi-cylindrical external part of the gripping part (10) forms a front part (12).
  • the opposite half of the cylinder, a rear face, is leaning directly against a front wall (24) of a connecting part (20) with the same width.
  • the connecting part (20) is a single-piece prismatic structure made of plastic injection.
  • a connecting part (20) is fixed at both ends of the gripping part (10).
  • the outward-facing lateral wall (26) of the connecting part (20) is flat and aligned with the corresponding lateral section (14) of the gripping part (10) in the same plane.
  • a hole (19) and a slot (17) are opened at the rear face in sequence, adjacent and at a distance to the lateral section (14).
  • the back wall (22) of the connecting part (20) has a hollow form separated by springs and extends from the back face (16) to the front part (12) through a casing (21) that allows a screw passage.
  • the front wall (24) of the connecting part (20) has a concave structure and is fully engaged with the rear face (16) of the gripping part (10).
  • a one-piece cap (30) resembling a cork and produced by plastic injection has been mounted on the handle covering both the gripping part (10) and the free ends of the connecting part (20).
  • the cap (30) includes a flat circular and straight plug (32) and from this narrow diameter, it contains a hollow cylindrical ring (36) that extends concentrically outward from its inner wall (322).
  • the ring (36) is integrated vertically to the inner wall (322) along its circular edge.
  • a 30-degree radial part of the ring (36) is emptied to provide an open section and forms a support wall (361) along its longitudinal edges opposite the open section.
  • a tab (34) in rod form and having a free end where the holder part is located extends vertically integrated into the inner wall (322) of the plug (32).
  • the tab (34) radially extends outward between the support walls (361), where the holder part is located.
  • the tab (34) is positioned between the support walls (361 ) outwardly from the center of the plug (32) and the ring (36).
  • the support walls (361 ) are set to lean against the filled area (16) from their opposite walls when the cap (30) is seated on the lateral section (14) in an assembly position.
