Abstract

A fastener for a transport container includes two portions to be connected and wherein the fastener includes a fastener flange arranged in a first cup and a displaceable fastener hook tiltably arranged in a second cup, the hook engaging behind the fastener flange in a closed position, it is provided in that at least one spring is disposed such that the fastener hook is pushed toward the bottom of the second cup into a rest position.

Claims

1. A fastener for a transport container having two portions to be connected, said fastener comprising:

a fastener flange arranged in a first cup and a displaceable fastener hook tiltably arranged in a second cup, said hook engaging behind said fastener flange in a closed position; and

at least one spring disposed such that said fastener hook is pushed toward a bottom of the second cup into a rest position.

2. A fastener as set forth in claim 1 including at least one further spring, a force action of which is directed such that said fastener hook may only engage behind said fastener flange when pressure is applied from outside.

3. A fastener as set forth in claim 1 including a bevel arranged in the first cup, said bevel guiding said fastener hook from the rest position to said fastener flange upon a displacement toward said fastener flange.

4. A fastener as set forth in claim 1 wherein said fastener hook includes a bevel guiding said fastener hook from the rest position to said fastener flange upon a displacement toward said fastener flange.

5. A fastener as set forth in claim 1 wherein said fastener flange is part of an opening of a fastener housing.

6. A fastener as set forth in claim 5 wherein said opening is closed by said at least one further spring which releases said opening upon pressure from outside.

7. A fastener as set forth in claim 6 wherein the force of said at least one further spring is larger than the force applied by said fastener hook to said at least one further spring by the effect of the at least one spring.

8. A fastener as set forth in claim 6 wherein said at least one further spring is a plate spring having an embossment in a region of said opening of said fastener housing.

9. A fastener as set forth in claim 1 wherein said at least one further spring is arranged at said fastener hook such that it closes said fastener hook in its rest position.

10. A fastener as set forth in claim 1 including a bolt serving to displace said fastener hook through an eccentric pivotable by a wing handle and that pins engaging into recesses in said bolt are formed at portions of the wing handle, said portions being bevelled substantially by 90°

.

11. A fastener for a transport container having two portions to be connected, said fastener comprising:

a fastener flange arranged in a first cup and a displaceable fastener hook tiltably arranged in a second cup, said hook engaging behind said fastener flange in a closed position; and

at least one spring disposed such that said fastener hook is pushed toward a bottom of the second cup into a rest position, and that a lifter disposed under said fastener hook co-operates with an embossment at the bottom of the second cup such that said fastener hook is lifted from a locked position for opening the fastener and is lowered into the locked position for closing same.

12. A fastener as set forth in claim 11 wherein said lifter is a further eccentric being rotatable by a bolt.

13. A fastener as set forth in claim 12 wherein said further eccentric has the shape of a spherical calotte.

14. A fastener as set forth in claim 11 wherein said lifter is arranged at said fastener hook.

15. A fastener as set forth in claim 14 wherein said lifter is formed by a chamfering of said fastener hook.

16. A fastener as set forth in claim 11 wherein said fastener flange is part of an opening of a fastener housing.

17. A fastener as set forth in claim 11 wherein the embossment at the bottom of the second cup is a stamping.
