US 6,732,976 B2 · Device for fastening a first part to a second part

Abstract

A device for fastening a first part to a second part, particularly for fastening a lining element in the interior of a vehicle, for example an aircraft, is provided with at least one fastening element connectable with the first part and releasably attachable to the second part. The fastening element is provided with a locking element that is supported on the fastening element so as to be movable between a disengaged position in which the fastening element is able to be set to the second part and to be detached therefrom, and a pre-locking position in which the fastening element is held at the second part. Further, the fastening element comprises an actuating element for moving the locking element between the disengaged position and the pre-locking position. The fastening element is further provided with a first biasing element for biasing the locking element into the pre-locking position thereof, and a trigger element comprising at least one retaining projection for the locking element, the trigger element being supported on the fastening element between a retaining position in which the at least one retaining projection retains the locking element in the disengaged position thereof, and a releasing position in which the at least one retaining projection releases the locking element for moving into the pre-locking position. The trigger element is provided for abutting on the second part upon setting the fastening element to the second part.

A device for fastening a first part to a second part, the device comprising:

at least one fastening element connectable to the first part and releasably attachable to the second part, the at least one fastening element comprising:
a locking element being supported at the fastening element so as to be movable between a disengaged position in which the fastening element is able to be set to the second part and to be detached therefrom, and a pre-locking position in which the fastening element is held at the second part;
and
an actuating element for moving the locking element between the disengaged position and the pre-locking position;
a first biasing element for biasing the locking element into the pre-locking position thereof;
and
a trigger element comprising at least one retaining projection for the locking element,
wherein the trigger element is supported at the fastening element between a retaining position, in which the at least one retaining projection retains the locking element in the disengaged position thereof, and a releasing position, in which the at least one retaining projection releases the locking element for moving into the pre-locking position, and
wherein the trigger element abuts the second part when the fastening element is set to the second part.

A fastening element for releasably attaching a first part to a second part, the fastening element comprising:

a first part retaining portion for retaining the first part;
a basic body having a bore, which connects a first end to a second end of the basic body;
an actuating element being rotatably disposed in the bore of the basic body, such that an upper end of the actuating element projects beyond the second end of the basic body;
a stop being attached to the upper end of the actuating element such that the stop is fixedly attached to the actuating element;
a locking element positioned between the stop and the second end of the basic body, the locking element being rotatably displaced into either a disengaged position or a pre-locking position, the locking element being adapted to fit within an introduction opening of the second part in the disengaged position;
a torsion spring being displaced within the bore about the actuating element, the torsion spring having one end abutting the locking element and a second end fixedly held at the basic body for generating a bias against the locking element such that the locking element is rotatably displaced from the disengaged position to the pre-locking position;
and
a trigger element disposed between the locking element and the second end of the basic body, the trigger element being movable between a retaining position and a releasing position, the trigger element being biased via springs in a direction towards the locking element such that retaining projections, which are formed on the trigger element, contain the locking element in the disengaged position when the trigger element is in the retaining position.
