Abstract

A fastening element for fastening a first component to a second component. The fastening element includes an elastically deformable body and an elongated actuating member. The actuating member is movably guided relative to the body to be selectively movable further into or further out of the body. The body is configured to be elongated by moving the actuating member further into the body and applying a corresponding load onto the body and to elastically deform back by moving the actuating member further out of the body and releasing the load applied thereto. Further, the body is configured to have a smaller outer diameter when correspondingly elongated than when non-elongated and/or deformed back.

First claim

The invention claimed is:

1. A fastening element for fastening a first component to a second component, the fastening element comprising:
a body which is elastically deformable; and
an elongated actuating member, movably guided relative to the body to be selectively movable further into or further out of the body,
wherein the body is configured to be elongated by moving the actuating member further into the body and applying a corresponding load onto the body and to elastically deform back by moving the actuating member further out of the body and releasing the load applied thereto, and the body is configured to have a smaller outer diameter when correspondingly elongated than when at least one of non-elongated or deformed back
wherein the body is formed from an elastic plastic material.

2. The fastening element of claim 1 , wherein the fastening element is configured to be inserted into an opening of one of the first component and the second component or of a housing when the body is elongated, and to make at least a form-fit connection with the one of the first component and the second component or the housing when the body is at least one of non-elongated or deformed back.

3. The fastening element of claim 1 , wherein the actuating member comprises a pin-shaped section insertable or inserted at least in sections into the body and contactable or contacted with an inner side of the body.

4. The fastening element of claim 1 , wherein a longitudinal end of the actuating member facing the body has a contact surface configured to be brought into contact with an inner side of the body.

5. The fastening element of claim 1 , further comprising a guiding member fixed relative to the body and having a bushing section to guide the actuating member therein.

6. The fastening element of claim 5 , wherein the guiding member comprises an interface section arranged outside the body for at least one of gripping by a hand of a user or attaching one of the first component and the second component thereto.

7. The fastening element of claim 1 , wherein the body comprises a first section having a first degree of hardness and an adjoining second section having a second degree of hardness, and the second section has a lesser hardness than the first section.

8. The fastening element of claim 1 , wherein the body comprises a shoulder section radially expanded and a section elongatable by the actuating member.

9. The fastening element of claim 1 , further comprising a housing having an opening and configured to selectively accommodate at least a section of the body, the body being insertable through the opening into the housing when elongated and intersecting with the housing when at least one of non-elongated or deformed back.

10. The fastening element of claim 9 , wherein the housing is configured to be attached to one of the first component and the second component.

11. The fastening element of claim 9 , wherein the housing comprises an accommodation compartment configured to at least partially accommodate the body, and the accommodation compartment is configured to be at least substantially airtightly sealable by the body.

12. The fastening element of claim 1 , wherein the elastic plastic material comprises at least one of a rubber or an elastomer.

13. An aircraft, comprising at least one fastening element according to claim 1 used for fastening a first component to a second component of the aircraft.

14. A fastening element for fastening a first component to a second component, the fastening element comprising:
a body which is elastically deformable; and
an elongated actuating member, movably guided relative to the body to be selectively movable further into or further out of the body,
wherein the body is configured to be elongated by moving the actuating member further into the body and applying a corresponding load onto the body and to elastically deform back by moving the actuating member further out of the body and releasing the load applied thereto, and the body is configured to have a smaller outer diameter when correspondingly elongated than when at least one of non-elongated or deformed back,
wherein the body comprises a first section having a first degree of hardness and an adjoining second section having a second degree of hardness, and the second section has a lesser hardness than the first section.
