Abstract
A snap-together fastening device includes a holding element and an actuating element. The holding element has one or more fixing arms that are actuatable from a mounting position into a fixing position. The actuating element is pluggable into an opening of the holding element, and has a top end and a bottom end. The actuating element deflects, in its position in which it is plugged into the holding element, at least one fixing arm into a fixing position. In its position in which it is plugged into the holding element an outermost edge of the actuating element, that is in the region of the top end, contacts an inner surface of the at least one fixing arm.
Claims14
A snap-together fastening device for plug-in mounting into an opening, the fastening device comprising:
- a holding element having one or more fixing arms actuatable from a mounting position into a fixing position and a central fastening element configured to connect to an external fastening element;
- and
- an actuating element that is pluggable into an opening surrounding the central fastening element, the actuating element having a top end including an annular element and a bottom end, wherein
- the actuating element deflects, in its position in which it is plugged into the holding element, at least one fixing arm into a fixing position, and
- in its position in which it is plugged into the holding element, a radially outermost edge of the actuating element, that is in the region of the top end below the annular element, directly contacts a radially inner surface of the at least one fixing arm.
A method of producing an integrated fastening structure on or in a sandwich component having a core layer, the method comprising the acts of:
- introducing a holding element of a fastening device into an opening provided in the sandwich component or introducing the holding element directly into the sandwich component, wherein the holding element comprises one or more fixing arms actuatable from a mounting position into a fixing position, and a central fastening element configured to connect to an external fastening element;
- and
- actuating the holding element via an actuating element pluggable into an opening surrounding the central fastening element, the actuating element having a top end including an annular element and a bottom end and deflecting the one or more fixing arms into the fixing position when plugged into the holding element, whereby the one or more fixing arms penetrate with at least one section provided for fixing into the core layer of the sandwich component, wherein
- in its position in which it is plugged into the holding element a radially outermost edge of the actuating element, that is in the region of the top end below the annular member, directly contacts a radially inner surface of the at least one fixing arm.
