Embodiment Construction
[0054] figure 1 A first main type of embodiment of the fastening device according to the invention is shown in a sectional view in a first position. The longitudinal axis L runs through the fastening device in a vertical direction; the vertical direction is at the same time the insertion direction. The fastening body part 1 is inserted into the fastening base part 2 which may be one part. The fastening body part 3 has a multi-part (separate part 3') fastening element 3. Specifically, the fixing part 3 is designed to be inserted into the fastening base part 2 .
[0055] The fastening element 3 is suitable for closed and / or frictional fastening of the fastening device in the fastening base 2 . To this end, the fixing part 3 is movable in at least one first direction R1. Currently, there are two first directions R1 since the two separate parts 3' are movable radially outwards. In order to disengage the fixing element 3, the individual parts 3' are respectively movable in a s...

The invention relates to the field of joining technology. More precisely, the invention relates to the field of releasable screw-like joining means. The remotely controllable fastening means for releasably joining components has a longitudinal axis (L) and at least one fastening body (1) for introduction into a fastening substrate (2), wherein the fastening body (1) has an anchor (3) which can be introduced into the fastening substrate (2), and wherein the anchor (3) can be moved in at least a first direction (R1) in order to anchor the fastening means in the fastening substrate (2) in a positively locking and / or frictional manner and can be moved in a second direction (R2) which is opposed to said first direction (R1) in order to release said fastening means, and wherein the anchor (3) is connected to an inner remotely controllable drive (4) which can be driven by fluid, and can be moved by said drive (4) in at least the second direction (R2). The anchor (3) comprises at least two individual parts (3'), and the respectively first direction (R1), in which each of said individual parts (3') can be moved, extends radially away from the longitudinal axis (L), or the first direction (R1) is a rotation about the longitudinal axis (L) and the anchor (3) is a cylinder with an external thread.
Description
technical field [0001] The invention relates to the technical field of installation. More specifically, the invention relates to the field of removable screw-like fastening devices. Background technique [0002] Research status and deficiencies in the field [0003] Fastening devices for the detachable connection of objects have been known for a long time in the form of bolted connections. Herein, a first movable body, presently referred to as a "fastening body", (shown separately) is connected by relative rotational movement to a suitable second body, presently referred to as a "fastening base". The second body may also be movable (movable), or it may be substantially stationary (immobile). [0004] The fastening means can have an external thread (screw). The fastening base has a suitable internal thread. The fastening base can also be movable (nut) and thus be used exclusively for fastening. However, the fastening base can also be arranged in another body or be part ...
