A screw joint arrangement and a device comprising at least one screw joint arrangement

Abstract

A screw engagement configuration includes: a first component (100) having at least one screw receiving portion (101); a second component (200) having a hole (201) including a first threaded hole portion (202), a second threaded hole portion (203), and a non-threaded hole portion (204) separating the first threaded hole portion (202) from the second threaded hole portion (203); and a screw (300) including a screw head (301) and a screw shaft (302) having a threaded screw portion (303). The first component (100) is configured close to the second component (200), wherein the first threaded hole portion (202) is close to the first component (100). The screw engagement configuration can be set between a first state in which the second component (200) is fixed relative to the first component (100) and a second state in which the second component (200) is movable relative to the first component (100) by rotation of the screw (300). In the first state, one of the at least one screw receiving portion (101) is aligned with the hole (201), and the screw shaft (302) extends through the at least one screw receiving portion (101) into the hole (201), wherein the threaded screw portion (303) engages the second threaded hole portion (203), such that the first component (100) is clamped between the screw head (301) and the second component (200). In the second state, the screw shaft (302) extends through the first threaded hole portion (202), and the threaded screw portion (303) is positioned in the non-threaded hole portion (204) of the hole (201). A screw joint arrangement comprising: a first member (100) provided with at least one screw receiving portion (101); a second member (200) provided with a bore (201) comprising a first threaded bore portion (202), a second threaded bore portion (203), and a non-threaded bore portion (204) separating the first threaded bore portion (202) and the second threaded bore portion (203); and a screw (300) comprising a screw head (301) and a screw shaft (302) provided with a threaded screw portion (303). The first member (100) is arranged next to the second member (200) with the first threaded bore portion (202) being proximal to the first member (100). The screw joint arrangement is settable, by rotation of the screw (300), between a first state in which the second member (200) is fixed relative to the first member (100), and a second state in which the second member (200) is movable relative to the first member (100).In said first state, one of the at least one screw receiving portion (101) and the bore (201) are aligned, and the screw shaft (302) extends through said one of the at least one screw receiving portion (101) and into the bore (201) with the threaded screw portion (303) engaging the second threaded bore portion (203) such that the first member (100) is clamped between the screw head (301) and the second member (200). In said second state, the screw shaft (302) extends through the first threaded bore portion (202) and the threaded screw portion (303) is positioned in the non-threaded bore portion (204) of the bore (201).
