The invention relates to a height adjustment device according to claim 1.

From the prior art, a worktop with a mounted in the worktop mounting recess is already known, which is limited by an introduced into the worktop stage. To install a hob in the worktop a sealing material is applied to the stage. Subsequently, a lateral boundary of a hob plate of the hob is placed on the sealing material. A vertical position of the hob relative to the worktop is fixed unchangeable by a given configuration. In addition, when introducing the hob in the mounting recess is a danger to pinch a finger between the hob and the worktop.

The object of the invention is in particular to provide a generic device with improved properties in terms of ease of installation. The object is achieved by the features of claim 1, while advantageous embodiments and modifications of the invention can be taken from the dependent claims.

It is proposed a height adjustment device for a hob, with a height adjustment unit, which is provided for a particular reversible change of a vertical position of the hob relative to a countertop, and with at least one fastening element which is provided, the height adjustment unit on the hob, in particular on a Housing unit of the hob to attach. The height adjustment device is especially designed and / or designed for the hob. In particular, the height adjustment device is provided specifically for the hob. The height adjustment device is particularly intended to move the hob in a vertical direction relative to the worktop to change the vertical position of the hob relative to the worktop. In particular, the height adjustment device is provided for changing the vertical position of the hob relative to the work surface to change a potential energy of the hob relative to the worktop, in particular to increase and / or decrease. For example, the height adjustment unit could at least for the most part comprise a metallic material, such as steel. Alternatively or additionally, the height adjustment unit could at least to a large extent be a plastic and / or a glass fiber and / or a textile fiber and / or a composite of said materials. By "at least to a large extent" should be understood in particular to a proportion of at least 70%, in particular at least 80%, advantageously at least 90% and preferably at least 95%. A "vertical position" of an object is to be understood in particular as meaning a position of the object in a vertical direction, which is oriented in particular parallel to a direction of gravity. The vertical direction is aligned in a mounting position, in particular perpendicular to a substrate. The substrate is in particular a floor and / or a floor and / or a footprint. In particular, the vertical direction is aligned perpendicular to a main extension plane of the hob and / or to a main extension plane of the worktop. A "main extension plane" of an object should be understood to mean, in particular, a plane which is parallel to a largest side surface of a smallest imaginary geometric cuboid which just completely encloses the object, and in particular runs through the center of the cuboid. The fastening element could in particular be provided to fasten the height adjustment unit to the hob, in particular by means of a connection which can be released exclusively by means of a tool.

The hob 12 together with the screwed to the hob 12 height adjustment device 10 is inserted into the mounting recess 48.

Subsequent to the pre-assembly step, the vertical position of the hob 12 relative to a worktop 16 is changed by means of the height adjustment device 10. To change the vertical position of the hob 12 relative to a worktop 16, the fastener 18 is rotated starting from the maximum screwed position of the Schraubausnehmung 58, in particular by a distance between the height adjustment unit 14 and the hob plate 34, in particular between the support element 20 and the hob plate 34, to enlarge.

The fastening element 18 is unscrewed from the screw recess 58 until the hob plate 34 is arranged substantially flush with the worktop 16 (see FIG. Fig. 13 ). The hob 12 is in a final vertical position of the hob 12 relative to a worktop 16th

In the final vertical position of the hob 12 relative to a worktop 16 is a gap 38 between the hob plate 34 and the worktop 16, in particular between the hob plate 34 and the step 50 of the worktop 16. The space 38 between the hob plate 34 and the worktop 16th is filled in the final vertical position of the hob 12 relative to a worktop 16 with a sealing material 40 (see. Fig. 14 ). In the present embodiment, the sealing material 40 is partially liquid, in particular viscous. The vertical position of the hob 12 relative to a worktop 16 is fixed by means of the sealing material 40.
