Abstract
A quick mounting nut (2) movable, at least partially, without being rotated, axially to a threaded bolt (1), with a springing wire clip (4) being located in a nut housing (5) with a continuous coaxial opening (6), with the wire clip (4) at least partially engaging in a bolt thread (3) and having two legs (8, 8′) which spring relative to one another, with the opening (6) having an inner cone (7) which narrows radially from an axial neutral position of the wire clip (4) and with the wire clip (4) being movable axially to a limited extent and contacting at least partially inside the inner cone (7) in its locking position.
Claims9
A quick mounting nut, comprising a housing (5) having a through-opening (6) through which a threaded bolt (1) is extendable;
- and a wire clip (4) located in the through-opening (6) for locking the threaded bolt (1) in the housing and having two legs (8, 8′) springable relative to each other and engaging a bolt thread (3) in a locking position of the wire clip (4), the wire clip (4) being axially displaceable between a neutral position in which the bolt (1) can be inserted into the nut and the locking position, the through-opening (6) having an inner cone narrowing radially from the neutral position of the wire clip (4), and the wire clip (4) contacting, at least partially, an inner surface of the cone (1) in the locking position thereof.
- wherein the wire clip legs (8, 8′) form in a radial plane, a circular arc-shaped middle part (9) engaging the bolt thread (3) at least partially along a bolt thread circumference, and
- wherein the nut housing (5) is formed of at least two shells (13a, 13b), and wherein the nut further comprises locking means (14) for positively connecting the two shells (13a, 13b) without a possibility thereof to rotate relative to each other wherein one of the shells, which is formed as a cover shell (13b), is provided, on an inner side thereof, with a radially expandable coaxial cone sleeve having an outer circumferential groove (23) for receiving the arc-shaped middle part (9) of the wire clip (4) to thereby tensionlessly secure the wire clip (4).
A mounting assembly, comprising a first quick mounting nut formed as a rail nut (20) and having a housing (5) formed of at least two shells (13a, 13b) and having a through-opening (6) through which a threaded bolt (1) is extendable, and a wire clip (4) located in the through-opening (6) for locking the threaded bolt (1) in the housing and having two legs (8, 8′) springable relative to each other and engaging a bolt thread (3) in a locking position of the wire clip (4), the wire clip (4) being axially displaceable between a neutral position in which the bolt (1) can be inserted into the nut and the locking position, the through-opening (6) having an inner cone narrowing radially from the neutral position of the wire clip (4), and the wire clip (4) contacting at least partially an inner surface of the cone (7) in the locking position thereof, and a second quick mounting nut (2′).
