Description

A DOOR HANDLE FOR AN OVEN

TECHNICAL FIELD

The invention relates to a multi-part handle adapted to a hinged door for an oven.

PRIOR ART

A hinged door on the oven covers an opening leading to the cooking chamber. In order for the door to be easily opened by the user, 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. To avoid exposing the lateral walls of the profile, 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.

BRIEF DESCRIPTION OF THE INVENTION

The object of the invention is to facilitate the assembly of the profile cover to an oven handle with a profile structure gripping extension.

To achieve the above objective, 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.

In a preferred embodiment of the invention, 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.

In a preferred embodiment of the invention, 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.

In a preferred embodiment of the invention, 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. In a possible embodiment, the filling forms a D-like form with the profile section shape, for example, having a circular section.

In a preferred embodiment of the invention, 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.

In a preferred embodiment of the invention, 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.

In a preferred embodiment of the invention, 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. In a preferred embodiment of the invention, 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.

In a preferred embodiment of the invention, 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.

In a preferred embodiment of the invention, the gripping part is made of aluminum extrusion. In this case, the gripping part is strong enough to open the oven door and can be easily produced in a hollow rod structure.

In a preferred embodiment of the invention, 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. In this way, the gripping part is integrated with the connecting part, and the handle has the appearance of a single piece.

In a preferred embodiment of the invention, 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. In this case, 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.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter of the invention is described with references to examples without any limitation, only for a better understanding of the subject matter.

Figure 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.

As shown in Figure 2, 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. In the gripping part (10), 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).

In Figure 3, 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. The plug (32) covers the lateral section (14) from the outside in the assembly position.

Figure 4 shows a partial rear perspective of the parts forming the handle, with the connection part in a disassembled state. There is a linear channel (29) on the outward-facing lateral wall (26) of the connecting part (20), extending from the front wall (24) to the back wall (22) at a distance. The channel (29) extends transversely within the connecting part (20). The end of the channel (29) forms a slit-like mouth (28) and can be accessed from the lateral wall (26). The thickness of the gripping part (10) is chosen to be greater than the thickness of the connecting part (20). Thus, when viewed from the front, the front part (12) is visible and the connecting part (20) remains behind the gripping part (10) and is not visible. The casing (21) to which the screw will be attached is located between the inward-facing lateral wall (26) and the center in the connecting part (20). The AA section is shown in Figure 5. A pin (27), an extension integrated into the connecting part (20), passes into the corresponding hole (19) on the gripping part (10). In this way, the connecting part (20) is mounted to align exactly with the lateral wall (26) to the lateral section (14). An expanded slot (25) has been formed at the front end of the casing (21 ), reaching the front wall (24). The slot (25) is aligned with a corresponding counter-opening (17) and allows a connection element, such as a rivet, to sit in the slot (25) to lock over the opening (17). The cap (30) passes to the gripping part (10) in a form where its tab (34) sits in a slot (18) close to the mouth of the lateral section (14). In this case, the plug (32), providing support, is entirely and directly air-tightly covering the lateral section (14). The extension of the cap's (30) ring (36) is set from its inner wall to the gripping part (10). In this situation, the support wall (361) rests from its two opposite edges to the filled area (16), and the tab (34) passes from its free end into the slot (18). During assembly, since the free end of the tab (34) touches the filled area (16), it flexes radially inward and freely moves towards the opening of the ring (36) and, when aligned with the slot (18), it returns to its initial position and locks the cap (30) to the gripping part (10).
