Locking pin and related locking element
View Patent ↗A locking pin with a stud having locking means and retaining means, wherein the stud has at least two separate stud elements, one of which serves as the locking means and the other as the retaining means. The at least two stud elements are rotationally fixed and are connected releasably in axial direction.
1. A locking pin with a stud having locking means and retaining means, the stud having at least two separate stud elements, one of which serves as the locking means and the other as the retaining means, wherein the at least two stud elements are rotationally fixed and are connected releasably in an axial direction by a releasable clamp, wherein the clamp is connected to the stud elements in such a manner that the stud elements will separate automatically from at least one of the stud elements when a force exerted in an axial direction on the at least two stud elements exceeds a predetermined level.
2. The locking pin of claim 1 wherein each of the at least two stud elements has a groove which engages a segment of clamp, respectively, that points towards the radial interior.
3. The locking pin of claim 1 , where the at least two stud elements have respective connection segments that are not rotationally symmetrical and which form a rotationally fixed connection when engaged with one another.
4. The locking pin of claim 1 , wherein the locking means includes threads.
5. The locking pin of claim 1 , wherein the locking means includes a cross pin.
6. The locking pin of claim 1 , wherein a stud element is at least sectionally hollow.
7. A fastening system, comprising:
a locking pin with a stud having locking means and retaining means, the stud having at least two separate stud elements, one of which serves as the locking means and the other as the retaining means, and wherein the at least two stud elements are rotationally fixed and are connected releasably in axial direction by a releasable clamp, wherein the clamp is connected to the stud elements in such a manner that the stud elements will separate automatically from at least one of the stud elements when a force exerted in an axial direction on the at least two stud elements exceeds a predetermined level; and
a fastener connectable to the locking pin.
8. The fastening system of claim 7 , wherein the locking pin is a screw with external threads and the fastener is a nut with internal threads.
9. The fastening system of claim 7 , wherein the locking pin has a head on one side and a cross pin on the other side, wherein the fastener has a cam contour with a ramp and a recessed holding area opposite thereto.
10. The fastening system of claim 7 , wherein the fastener includes a housing with a cone and a divided nut received within the housing, wherein the segments of nut are axially displaceable relative to the cone against a force exerted by a spring element.
11. The fastening system of claim 7 , wherein the locking pin includes a head on one side and a central opening with interior threads on the other side, wherein the fastener includes a housing having rotationally fixed retaining cam screw therein with exterior threads and a ratchet assembly.
12. The fastening system of claim 7 , further comprising a disk to support a head of locking pin, and wherein the underside of the head and the counter contour of the disk have spherical surfaces.
