Claims (18)

1. 1. A part of a ski fastening system comprising a housing (3; 8) with an axial sleeve (13) passing through it, completely or partially, with an internal diameter (14), in which two pins (1), configured to move in each direction, are arranged with at least one intermediate spring element (2), wherein the pins (1) are configured to slide in the sleeve (13) between a protruding and a retracted position, characterized in that the part of the pins (1), which is open when the pins (1) are in the protruding position, has an external diameter (15) smaller than the internal diameter (14) of the sleeve (13).
2. 2. A part of the fastening system according to paragraph 1, characterized in that the reduced diameter of the pin (1) is unchanged.
3. 3. A part of the fastening system according to paragraph 1, characterized in that the head end of the pin (1) is rounded with a constant radius of curvature.
4. 4. A part of the fastening system according to paragraph 1, characterized in that the head end of the pin (1) has a radius of curvature in the range of 1-3.
5. 5. A part of the fastening system according to paragraph 4, characterized in that the head end of the pin (1) has a radius of curvature of 2.
6. 6. A part of the fastening system according to paragraph 1, characterized in that the pins (1) contain a base (9), wherein the base has a diameter greater than the inner diameter (14) of the sleeve (13).
7. 7. A part of the fastening system according to paragraph 1, characterized in that the sleeve (13), through which the pins (1) pass, consists of inserts (10), which are pressed into the housing (3; 8).
8. 8. A part of the fastening system according to claim 1, characterized in that the housing (3) contains a closable opening (16) that provides access from the side to the part of the sleeve (13).
9. 9. A part of the fastening system according to paragraph 8, characterized in that the size of the opening (16) is sufficient for mounting and dismounting the pins (1) and at least one spring element (2).
10. 10. A part of the fastening system according to paragraph 8, characterized in that the opening (16) is provided with a cover (5).
11. 11. A part of the fastening system according to claim 1, characterized in that the insert (10) is provided with at least one container (11) for lubrication in the form of a hole, opening, groove or recess.
12. 12. A part of the fastening system according to claim 7, characterized in that at least one container (11) for lubricant in the insert (10) is provided at a distance from the outer edge (12) of the insert (11), which is deeper than the pin segment (1) with a reduced diameter.
13. 13. A part of the fastening system according to paragraph 1, characterized in that each pin (1) is provided with at least one sealing ring (4), which completely or partially seals the space between the outer surface of the pins (1) and the inner surface of the sleeve (13).
14. 14. A part of the fastening system according to paragraph 1, characterized in that the insert (10) is made with grooves on the outer surface.
15. 15. A part of the fastening system according to claim 6, characterized in that each pin (1) is provided with at least one sealing ring (4), which completely or partially seals the space between the base (9) of the pins (1) and the inner edge (15) of the insert (10).
16. 16. A part of the fastening system according to claim 6, characterized in that each pin (1) is provided with 2 sealing rings (4, 4'), wherein the first sealing ring (4) is adjacent to the base (9) of the pin, and the second sealing ring (4') is located in a radial, annular groove in the pin, wherein the second sealing ring (4') is provided at a distance from the outer edge (12) of the insert (10), which is deeper than the outermost inner edge of the container (11) for lubricant, when the pin (1) is in a protruding state.
17. 17. A method for servicing a part of the fastening system according to claim 1 or 7, characterized in that one of the pins (1) is pushed so far beyond the normal retracted operating position that the portion of the pin (1) with a reduced diameter enters inside the part of the sleeve (13) or insert (10) that is furthest from the outer surface to form a gap between the pin (1) and the insert (10), along which grease can be pressed and further along the base into the spring (2) in the spring chamber.
18. 18. A method for servicing a part of the fastening system according to claim 17, characterized in that one of the pins (1) is pushed so far from the normal retracted operating position that the part of the pin (1) with a reduced diameter overlaps the part of the insert (10) containing the lubricant reservoir, so that a gap is formed between the pin (1) and the insert (10), through which the grease can be pressed and then pass into the lubricant reservoir (11).
