Add-on piece for fastening to a panel element

Abstract

An add-on piece for fastening to a panel element includes a base body, a fastening element, and a guiding element and a mating guiding element which are configured to guide the fastening element with respect to the base body such that during assembling of the add-on piece on the panel element, the fastening element moves away from the base body and comes into engagement with the panel element for fastening the add-on piece to the panel element.

1 . An add-on piece for fastening to a panel element, said add-on piece comprising:
 a base body;   a fastening element; and   a guiding element and a mating guiding element which are configured to guide the fastening element with respect to the base body such that during assembling of the add-on piece on the panel element, the fastening element moves away from the base body and comes into engagement with the panel element for fastening the add-on piece to the panel element.   
     
     
         2 . The add-on piece of  claim 1 , wherein the guiding element and the mating guiding element are configured to guide in a pre-assembled state of the add-on piece the fastening element such that the fastening element is blocked in a releasable manner from moving away from the base body. 
     
     
         3 . The add-on piece of  claim 2 , wherein, when the fastening element is engaged with the panel element in an assembled state of the add-on piece, the add-on piece is movable between the pre-assembled state and the assembled state by moving the fastening element away from the base body, with the fastening element being blocked in the assembled state from moving back to the base body. 
     
     
         4 . The add-on piece of  claim 3 , wherein in the assembled state the fastening element is blocked in a releasable manner from moving back to the base body. 
     
     
         5 . The add-on piece of  claim 3 , wherein the fastening element is displaced in a straight line, when moving away from the base body and/or moving back to the base body. 
     
     
         6 . The add-on piece of  claim 5 , wherein the straight line is inclined with respect to an assembling direction. 
     
     
         7 . The add-on piece of  claim 1 , wherein the base body is movable in an assembling direction towards the panel element for assembling the add-on piece so that the fastening element and/or one of the guiding element and the mating guiding element comes into contact with the panel element to cause the fastening element to move away from the base body. 
     
     
         8 . The add-on piece of  claim 1 , wherein the guiding element is a rail and the mating guiding element has a profile that encompasses the rail. 
     
     
         9 . The add-on piece of  claim 8 , wherein the rail is inclined with respect to an assembling direction. 
     
     
         10 . The add-on piece of  claim 3 , wherein the guiding element and the mating guiding element are configured in one of two ways, a first way in which the guiding element and the mating guiding element latch in a releasable manner with one another for releasably blocking the fastening element to move away and/or block the fastening from moving back, a second way in which the guiding element and the mating guiding element latch in a releasable manner with a further element. 
     
     
         11 . The add-on piece of  claim 1 , wherein one of the guiding element and the mating guiding element is fastened to the base body via a wedge. 
     
     
         12 . The add-on piece of  claim 11 , wherein one of the guiding element and the mating guiding element and/or the wedge is formed as one piece with the base body and/or the other one of the guiding element and the mating guiding element is formed as one piece with the fastening element. 
     
     
         13 . The add-on piece of  claim 1 , wherein the fastening element comprises a first fastening element which is guided by the guiding element and mating guiding element with respect to the base body, and a second fastening element, with the first and second fastening elements being arranged on opposite sides of the base body, and further comprising a further guiding element and a further mating guiding element configured to guide the second fastening element with respect to the base body such that during assembling of the add-on piece on the panel element, the second fastening element moves away from the base body and comes into engagement with the panel element for fastening the add-on piece to the panel element, with the first and second fastening elements moving away from the base body in opposite directions. 
     
     
         14 . The add-on piece of  claim 1 , wherein the base body is formed from two half shells that are connected to one another. 
     
     
         15 . The add-on piece of  claim 1 , wherein the base body comprises a display facility in particular a display, an operating element, in particular a switch or a switch receptacle, a receptacle for a recessible rotary knob, a positioning facility for positioning the panel element with respect to a carcass of the cooking appliance, a communication facility, in particular a WLAN module, a loud speaker facility and/or other fastenings to the appliance, in particular a steam hinge. 
     
     
         16 . A panel system, comprising:
 a panel element; and   an add-on piece comprising a base body, a fastening element, and a guiding element and a mating guiding element which are configured to guide the fastening element with respect to the base body such that during assembling of the add-on piece on the panel element, the fastening element moves away from the base body and comes into engagement with the panel element for fastening the add-on piece to the panel element.   
     
     
         17 . The panel system of  claim 16 , and further comprising a rotary knob, said add-on piece configured as a switch receptacle for receiving the rotary knob. 
     
     
         18 . A cooking appliance, comprising a panel system, said panel system comprising a panel element, and an add-on piece which comprises a base body, a fastening element, and a guiding element and a mating guiding element which are configured to guide the fastening element with respect to the base body such that during assembling of the add-on piece on the panel element, the fastening element moves away from the base body and comes into engagement with the panel element for fastening the add-on piece to the panel element. 
     
     
         19 . The cooking appliance of  claim 18 , constructed in a form of a cooker or baking oven.
