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 comprising:

a first cup adapted to be arranged on one of two portions of a transport container;

a second cup adapted to be arranged on another of the two portions of the transport container, the two portions of the transport container being spaced apart in an open state and movable relative to one another when said fastener is in an unlocked state, said second cup having an embossment comprising a raised portion extending upwardly from a bottom thereof for operative engagement with a fastener hook upon closing the two portions of the transport container;

a fastener housing arranged in said first cup;

a fastener hook being displaceable and being tiltably arranged in said second cup;

a spring disposed in said second cup to bias said fastener hook toward a bottom of said second cup;

said fastener hook being displaced longitudinally toward said fastener housing upon closing the two portions of the transport container and said fastener hook contacting said fastener housing and being operatively engaged with said embossment to cause said fastener hook to tilt and to engage said fastener housing, said fastener hook engaging said fastener housing in a locked state of said fastener;

wherein said fastener hook includes a hook-shaped portion; and

wherein said fastener housing includes an opening to receive said hook-shaped portion of said fastener hook in the locked state of said fastener.

2. A fastener as set forth in claim 1 including a tiltable guiding disposed in said second cup to movably support said fastener hook in a longitudinal direction.

3. A fastener as set forth in claim 2 including a housing disposed in said second cup to support said tiltable guiding.

6. A fastener as set forth in claim 1 including an eccentric disposed under said fastener hook and co-operating with said embossment at the bottom of said second cup.

7. A fastener as set forth in claim 6 including a rotatable bolt connected to said eccentric to rotate said eccentric.

8. A fastener as set forth in claim 7 including a wing handle cooperating with said bolt to rotate said bolt.

4. A fastener comprising:

a first cup adapted to be arranged on one of two portions of a transport container;

a second cup adapted to be arranged on another of the two portions of the transport container, the two portions of the transport container being spaced apart in an open state and movable relative to one another when said fastener is in an unlocked state, said second cup having an embossment at a bottom thereof;

a fastener housing arranged in said first cup;

a displaceable fastener hook tiltably arranged in said second cup and displaceable relative to said fastener housing;

a spring disposed in said second cup to bias said fastener hook toward a bottom of said second cup;

said fastener hook being displaced longitudinally toward said fastener housing upon closing the two portions of the transport container and said fastener hook contacting said fastener housing and being operatively engaged with said embossment to cause said fastener hook to tilt and to engage said fastener housing, said fastener hook engaging said fastener housing in a locked state of said fastener;

a tiltable guiding disposed in said second cup to movably support said fastener hook in a longitudinal direction; and

wherein said housing of said second cup includes at least one further spring disposed in said second cup and supported by said housing and cooperating with said tiltable guiding to serve as an axis for said tiltable guiding.

5. A fastener as set forth in claim 4 wherein said at least one further spring has a spring force larger than a spring force applied by said spring to said fastener hook.

9. A fastener comprising:

a first cup adapted to be arranged on one of two portions of a transport container;

a second cup adapted to be arranged on another of the two portions of the transport container, the two portions of the transport container being spaced apart in an open state and movable relative to one another when said fastener is in an unlocked state, said second cup having an embossment at a bottom thereof;

a fastener housing arranged in said first cup;

a displaceable fastener hook tiltably arranged in said second cup and displaceable relative to said fastener housing;

a spring disposed in said second cup to bias said fastener hook toward a bottom of said second cup;

a lifter disposed under said fastener hook and co-operating with said embossment at the bottom of said second cup, wherein said fastener hook is displaced longitudinally toward said fastener housing upon closing the two portions of the transport container and said lifter engages said embossment and causing said fastener hook to tilt and be lifted from a locked state for opening said fastener and lowered into the locked state for closing same such that said spring causes said fastener hook to maintain contact with said fastener flange in the locked state.

10. A fastener as set forth in claim 9 wherein said lifter comprises an eccentric.

11. A fastener as set forth in claim 10 wherein said eccentric has a shape of a spherical calotte.

12. A fastener as set forth in claim 10 including a rotatable bolt connected to said eccentric to rotate said eccentric.

13. A fastener as set forth in claim 12 wherein said bolt has recesses therein.

14. A fastener as set forth in claim 13 including a wing handle cooperating with said bolt to rotate said bolt.

15. A fastener as set forth in claim 14 wherein said wing handle has cams engaging into said recesses in said bolt.

16. A fastener as set forth in claim 9 wherein said fastener housing includes an opening to receive a portion of said fastener hook in the locked state of said fastener.

17. A fastener as set forth in claim 9 wherein the embossment at the bottom of the second cup is a stamping.

18. A fastener comprising:

a first cup adapted to be arranged on one of two portions of a transport container;

a second cup adapted to be arranged on another of the two portions of the transport container, the two portions of the transport container being spaced apart in an open state and movable relative to one another when said fastener is in an unlocked state, said second cup having an embossment at a bottom thereof;

a fastener housing arranged in said first cup;

a displaceable fastener hook tiltably arranged in said second cup and displaceable relative to said fastener housing;

a spring disposed in said second cup to bias said fastener hook toward a bottom of said second cup;

an eccentric disposed under said fastener hook and co-operating with said embossment at the bottom of said second cup, a rotatable bolt connected to said eccentric to rotate said eccentric, and a wing handle cooperating with said bolt to rotate said bolt; and

wherein said fastener hook is displaced longitudinally toward said fastener housing upon closing the two portions of the transport container and said eccentric engages said embossment and causes said fastener hook to tilt and be lifted from a locked state for opening said fastener and lowered into the locked state for closing same such that said spring causes said fastener hook to maintain contact with said fastener housing in the locked state.
