Adjustment joint, fastening elements and method for installation and position setting using an adjustment joint

Fastening elements for attaching objects and setting their positions, to which fastening elements (K, K1, K2) it is fitted at least one adjustment joint (S1, S2) for adjusting position, which adjustment joint (S1, S2) comprises at least two adjustment parts (S11, S12, S13, S21, S22, S23) arranged so as to be rotatable with respect to each other around (arrow R) a joint axis (A1, A2) and a locking element (S14, S15, S15a, S15b, S15c, S15d) arranged so as to function in the direction (arrow L) of said joint axis (A1, A2) for locking the adjustment parts (S11, S12, S13, S21, S22, S23) into a locked state so that the adjustment parts become immobile with respect to each other, wherein:

• the adjustment joint (S1, S2) is configured so as to be switched from the locked state to a fine adjustment mode by opening the locking element (S14, S15, S15a, S15b, S15c, S15d);
• the adjustment joint (S1, S2) is configured so as to be switched from the fine adjustment mode to a coarse adjustment mode by further opening the locking element (S14, S15, S15a, S15b, S15c, S15d);
• the adjustment joint (S1, S2) is configured so as to be switched from the coarse adjustment mode back to the fine adjustment mode and further from the fine adjustment mode to the locked state by tightening the locking element (S14, S15, S15a, S15b, S15c, S15d);
• fitted in connection with at least one adjustment joint (S1, S2) there are fine adjustment elements (F1, F1a, F1b, F2, F2a, F2b, F2c, F2d, F2e, F2f) for the adjustment of position of the adjustment joint (S1, S2) in the fine adjustment mode;
• and
• the adjustment joint is configured so that adjustments, if any, of the adjustment parts made in the fine adjustment mode and in the coarse adjustment mode are retained upon closing the locking element to cause the adjustment parts to be in the locked state.

A method of installation and setting of position of an adjustment joint, which adjustment joint (S1, S2) comprises at least two adjustment parts (S11, S12, S13, S21, S22, S23) rotatable with respect to each other around (arrow R) a joint axis (A1, A2), and a locking element (S14, S15, S15a, S15b, S15c, S15d) functioning in the direction (arrow L) of said joint axis (A1, A2) for locking the adjustment parts (S11, S12, S13, S21, S22, S23) into a locked state so that the adjustment parts become immobile with respect to each other, wherein:

• the adjustment joint (S1, S2) is switched from the locked state to a fine adjustment mode by opening the locking element (S14, S15, S15a, S15b, S15c, S15d);
• the adjustment joint (S1, S2) is switched from the fine adjustment mode to a coarse adjustment mode by further opening the locking element (S14, S15, S15a, S15b, S15c, S15d);
• the adjustment joint (S1, S2) is switched from the coarse adjustment mode back to the fine adjustment mode and further from the fine adjustment mode to the locked state by tightening the locking element (S14, S15, S15a, S15b, S15c, S15d);
• and
• adjustments, if any, of the adjustment parts made in the fine adjustment mode and in the coarse adjustment mode are retained upon closing the locking element to cause the adjustment parts to be in the locked state.
