Abstract

The present invention relates to a cooking hob (10) with at least two one-piece fastening elements (20) arranged at outer portions of the cooking hob (10). The fastening element (20) comprises a first portion (22) being permanently connected or connectable to an upper part (12) of the cooking hob (10). The fastening element (20) comprises a second portion (24) being detachably connected or connectable to a lower part (14) of the cooking hob (10), so that the upper part (12) and the lower part (14) form the cooking hob (10). The second portion (24) of the fastening element (20) comprises at least one spring element (26) at a sidewall of the cooking hob (10) in order to clamp the cooking hob (10) within a cutout (34) enclosing circumferentially the cooking hob (10). At least two fastening elements (20) are arranged at opposite sidewalls of the cooking hob (10). Further, the present invention relates to a one-piece fastening element.

First claim

The invention claimed is:

1. A one-piece fastening element for a cooking hob, comprising:
a first arm permanently attached to an underside of an upper part of the cooking hob;
a second arm detachably connectable to a sidewall of a lower part of the cooking hob, the second arm extending along the sidewall of the lower part of the cooking hob when connected to the upper part of the cooking hob, wherein the second arm comprises:
two end portions, each having a spring element biased away from the sidewall of the lower part of the cooking hob in order to clamp the cooking hob within a cutout enclosing circumferentially the cooking hob, and
a middle portion separated from and between the two end portions,
wherein the first arm of the fastening element and the second arm of the fastening element are formed at about 90 degrees and together form the one-piece fastening element, and
when fastened together by the one-piece fastening element, the upper part and the lower part form the cooking hob.

2. The fastening element according to claim 1 , wherein the first arm of the fastening element is glued to the underside of the upper part of the cooking hob.

3. The fastening element according to claim 1 , wherein the first arm of the fastening element comprises a bending for supporting at least a section of a circumferential side of the upper part of the cooking hob.

4. The fastening element according to claim 1 , wherein the middle portion of the second arm comprises an aperture with which a lug element on the sidewall of the lower part of the cooking hob is engageable.

5. The fastening element according to claim 1 , wherein the spring elements are U-shaped and/or leaf-springs.

6. The fastening element according to claim 4 , wherein the middle portion of the second arm further comprises a buckled appendix acting as a grip such that the middle portion is extendable away from the sidewall by pulling on the buckled appendix, thereby disengaging the lug element from the aperture.

7. The fastening element according to claim 4 , wherein the upper part of the cooking hob is a glass-ceramic panel.

8. A cooking hob comprising:
at least two fastening elements according to claim 1 ;
the upper part of the cooking hob; and
the lower part of the cooking hob,
wherein, a first fastening element and a second fastening element of the at least two fastening elements are permanently attached to the upper part of the cooking hob such that the second arms of the first and second fastening elements are detachably connectable to opposite sidewalls of the lower part of the cooking hob, and
wherein the spring elements of the first and second fastening elements have elastic properties which act in a radial direction away from their respective sidewalls of the lower part of the cooking hob so as to provide an elastic force in opposite directions and clamp the cooking hob within the cutout enclosing circumferentially the cooking hob.
