Abstract
In order to provide an anchor element for fastening an article to a further article, this anchor element being simple and inexpensive to produce and enabling an article to be fastened to a further article simply and reliably, it is proposed that the anchor element should include a base body that takes a hollow form, at least in certain regions, and surrounds a receiving space for receiving a fastening element, wherein the base body includes one or more elastically yielding spring elements that are formed by one or more wall portions of the base body, and these project into the receiving space in an installed condition of the anchor element.
Claims16
An anchor element for fastening an article to a further article, the anchor element comprising:
- a base body that takes a hollow form, at least in certain regions, and surrounds a receiving space for receiving a fastening element, wherein
- the base body includes one or more elastically yielding spring elements that are formed by one or more wall portions of the base body, and these project into the receiving space in an installed condition of the anchor element,
- one or more of said spring elements each have two side wings,
- one of the side wings is adjacent to an inlet for introducing a fixing element into said receiving space, and
- one other of the side wings is disposed away from the inlet,
- wherein said one or more elastically yielding spring elements of the base body each have two lateral flanks, and
- wherein the flanks form mutually different angles (α (alpha), β (beta)) with a direction of connection of the anchor element,
- wherein the anchor element includes one or more anchoring elements for anchoring the anchor element in an article,
- said one or more anchoring elements being formed by wall portions of the base body which, in an installed condition of the anchor element, starting from the sleeve, project outwards away from the receiving space,
- wherein in a condition that is ready for installation of the anchor element, said one or more anchoring elements, starting from the sleeve, project at least in certain regions into the receiving space, and
- one or more anchoring elements form barbs for anchoring the anchor element in an article.
An anchor element for fastening an article to a further article, the anchor element comprising:
- a base body that takes a hollow form, at least in certain regions, and surrounds a receiving space for receiving a fastening element, wherein
- the base body includes one or more elastically yielding spring elements that are formed by one or more wall portions of the base body, and these project into the receiving space in an installed condition of the anchor element, wherein
- the anchor element includes one or more locking elements for locking one or more spring elements in a pre-stressed condition, wherein
- one or more locking elements are formed by wall portions of the base body, and wherein
- one or more locking elements project into the receiving space and, when a fastening element is inserted into the receiving space, are actuable for the purpose of releasing one or more spring elements.
An anchor element for fastening an article to a further article, the anchor element comprising:
- a base body that takes a hollow form, at least in certain regions, and surrounds a receiving space for receiving a fastening element, wherein
- the base body includes one or more elastically yielding spring elements that are formed by one or more wall portions of the base body, and these project into the receiving space in an installed condition of the anchor element, and
- the anchor element includes one or more fluid receptacles for receiving a fluid, in particular for receiving adhesive.
A fastening device for fastening an article to a further article, including:
- a base body that takes a hollow form, at least in certain regions, and surrounds a receiving space for receiving a fastening element, wherein
- the base body includes one or more elastically yielding spring elements that are formed by one or more wall portions of the base body, and these project into the receiving space in an installed condition of an anchor element,
- the fastening element for inserting and fixing in the anchor element,
- wherein an end of a fastening portion of the fastening element that is remote from an anchoring portion of the fastening element is formed to taper in the direction away from the anchoring portion.
A fastening device for fastening an article to a further article, including:
- a base body that takes a hollow form, at least in certain regions, and surrounds a receiving space for receiving a fastening element, wherein
- the base body includes one or more elastically yielding spring elements that are formed by one or more wall portions of the base body, and these project into the receiving space in an installed condition of an anchor element,
- the fastening element for inserting and fixing in the anchor elements
- wherein an end of a fastening portion of the fastening element that is remote from an anchoring portion of the fastening element is provided with a tool receptacle.
A fastening device for fastening an article to a further article, including:
- a base body that takes a hollow form, at least in certain regions, and surrounds a receiving space for receiving a fastening element, wherein
- the base body includes one or more elastically yielding spring elements that are formed by one or more wall portions of the base body, and these project into the receiving space in an installed condition of an anchor element,
- the fastening element for inserting and fixing in the anchor element,
- wherein two mutually opposite ends of a fastening element are anchorable to a respective article by means of a respective anchor element.
