Description

[0001] The present invention relates to a door hinge device for an oven cavity of a cooking oven according to the preamble of claim 1. Further, the present invention relates to a cooking oven according to the preamble of claim 12.

[0002] The oven cavity is closable by a pivoting oven door arranged at the front side of said oven cavity. Usually the oven door is mounted at the oven cavity by two door hinges. One lever of the door hinge is attached in the sidewall of the oven cavity. Another lever is attached in or at the oven door.

[0003] However, it is laborious, if the oven door has to be removed, since the door hinge is fastened by several fixing elements. Further, the fixing elements are often difficult to access. For example, parts of the oven cavity must be removed in order to dismount the door hinge.

[0004] It is an object of the present invention to provide a door hinge device for an oven cavity of a cooking oven, wherein the proper door hinge is easily removable from the cooking oven.

[0005] The object of the present invention is achieved by the door hinge device according to claim 1.

[0006] According to the present invention the door hinge device comprises a holder attached or attachable at a side panel of the oven cavity, and the oven lever of the door hinge is removably inserted in or removably insertable into a guiding assembly of the holder.

[0007] The core of the present invention is the structure of the holder. Said holder can be permanently fastened at the side panel of the oven cavity on the one hand and can include the door lever of the door hinge on the other hand, wherein the door lever is insertable into and removable from the guiding assembly in an easy way.

[0008] According to a preferred embodiment of the present invention the holder is made of a sheet by folding. The folding of the sheet allows low complexity.

[0009] Preferably, the guiding assembly of the holder has a U-shaped cross-section. The guiding assembly may be an integrated part of the holder.

[0010] In particular, the guiding assembly comprises at least one screw for fixing the oven lever. Preferably, the guiding assembly comprises only one screw for fixing the oven lever, which allows a quick installation and removal of the oven door.

[0011] According to a preferred embodiment of the present invention the screw is arranged in a front portion of the guiding assembly. In this case the screw is easily accessible.

[0012] Further, the guiding assembly comprises at least one spring for clamping the oven lever. The oven lever can be fastened by the spring without any further steps.

[0013] Preferably, the spring is arranged in a rear portion of the guiding assembly. In particular, the spring is formed as a U-shaped cut-out. This kind of spring can be realized by low cost of materials.

[0014] Further, the guiding assembly comprises at least one fixation flange for keeping the oven lever in its position. In particular, the fixation flange may act perpendicular to the longitudinal axis of the oven lever. Preferably, the fixation flange is arranged in a rear portion of the guiding assembly.

[0015] The present relates further to a cooking oven with at least one oven cavity and at least one oven door for closing said oven cavity, wherein the cooking oven comprises at least one door hinge device as described above.

[0016] In particular, the oven cavity comprises a front frame with at least one cut-out, wherein the at least one guiding device and/or the at least one oven lever penetrates through said cut-out.

[0017] Typically, the cooking oven comprises a pair of door hinge devices arranged at the two side panels of the oven cavity.

[0018] Novel and inventive features of the present invention are set forth in the appended claims.

[0019] The present invention will be described in further detail with reference to the accompanied drawings, in which

FIG 1

illustrates a perspective view of a door hinge device for an oven cavity of a cooking oven according to a preferred embodiment of the present invention, and

FIG 2

illustrates a perspective view of the door hinge device attached at a side panel of the oven cavity according to the preferred embodiment of the present invention.

[0020] FIG 1 illustrates a perspective view of a door hinge device for an oven cavity 36 of a cooking oven according to a preferred embodiment of the present invention. The door hinge device comprises a door hinge 10 and a holder 18. In FIG 1 a part of the door hinge 10 is inserted in the holder 18.

[0021] The door hinge 10 includes an oven lever 12 and a door lever 14. The oven lever 12 and the door lever 14 are interconnected by a hinge element 16. The door lever 14 is provided for being fastened at and/or in an oven door. The oven lever 12 is inserted in a guiding assembly 20 of the holder 18. The oven lever 12 is insertable along its longitudinal direction into the guiding assembly 20.

[0022] The guiding assembly 20 of the holder 18 is substantially a channel with a U-shaped cross-section. The oven lever 14 comprises a rectangular cross-section, which is marginally smaller than the cross-section of the guiding assembly 20.

[0023] The holder 18 is made of sheet and comprises four parallel folding edges 22. Thus, the holder 18 comprises five sheet sections 24 and 26. Two outer sheet sections 24 are in the same plane and provided for lying against a side panel 38 at a sidewall of the oven cavity 36. Three inner sheet sections 26 form the U-shaped guiding assembly 20. In particular, the sheet is made of metal.

[0024] The outer sheet sections 24 are folded outwardly from the guiding assembly 20. When the outer sheet sections 24 lie against the side panel 38, then the guiding assembly 20 has a rectangular cross-section being marginally bigger than the cross-section of the oven lever 12.

[0025] In a rear portion of the guiding assembly 20 there is a spring 28 in the upper inner sheet section 26. The spring 28 is formed by a U-shaped cut-out. The spring 28 is provided for clamping the oven lever 12 of the door hinge 10.

[0026] In a central inner sheet section 26 of the guiding assembly 20 there is a fixation flange 30. The fixation flange 30 is also in the rear portion of the guiding assembly 20. The fixation flange 30 keeps the oven lever 12 in its position. The fixation flange 30 acts perpendicularly to the longitudinal axis of the oven lever 12.

[0027] The oven lever 12 of the door hinge 10 is fixed at the holder 18 by a screw 32. After the oven lever 12 has been inserted into the guiding assembly 20 of the holder 18, the only step for fastening the door hinge 10 is the tightening of the screw 32.

[0028] The holder 18 comprises bores 34 in the outer sheet sections 24. By said bores 34 and suitable fixing elements, like screws, the holder 18 can be fastened at the side panel 38 of the oven cavity.

[0029] FIG 2 illustrates a perspective view of the door hinge device attached at the side panel 38 of the oven cavity 36 according to the preferred embodiment of the present invention.

[0030] The holder 18 is attached at the side panel 38 of the oven cavity 36, wherein the outer sheet sections 24 of the holder 18 lie against said side panel 38. In this example, there are screw joints between the outer sheet sections 24 and the side panel 38. The oven cavity 36 comprises a front frame 40. The guiding assembly 20 and the oven lever 12 penetrate the front frame 40 through a cut-out 42 in a lower corner of said front frame 40.

[0031] The door hinge 10 and 10' is shown twice in FIG 2. A representation on the left hand side shows the door hinge 10, wherein the oven lever 12 has been inserted into the guiding assembly 20. Another representation on the right hand side shows the door hinge 10' before being inserted into the guiding assembly 20. The inserting direction is represented by an arrow 44.

[0032] The door hinge device according to the present invention allows a quick installation of an oven door in front of the oven cavity 10. Typically, the oven door comprises two door hinges 10. As a first step the oven levers 12 has to be inserted into the corresponding guiding assemblies 20. As a second step the screws 32 has to be tightened in order to fix the oven levers 12 in the guiding assemblies 20 and at the holder 18.

[0033] Although an illustrative embodiment of the present invention has been described herein with reference to the accompanying drawings, it is to be understood that the present invention is not limited to that precise embodiment, and that various other changes and modifications may be affected therein by one skilled in the art without departing from the scope or spirit of the invention. All such changes and modifications are intended to be included within the scope of the invention as defined by the appended claims.
