Abstract

The invention relates in first instance to a nut having a first part ( 11 ) which has a first through opening (O 1 ), and having a second part ( 12 ) which has a opening (O 2 ) having an opening contour, the parts ( 11, 12 ) being connected so as to be rotatable about a rotational axis (A) which passes through the openings (O 1 , O 2 ), and the openings (O 1 , O 2 ) being aligned with one another, in addition, the first opening (O 1 ) on its inner face having a profile which extends in the peripheral direction and which is interrupted in the peripheral direction. In order to provide a nut which is quickly mountable on a threaded bolt, and which has a simple design that allows greater security against the nut coming off the threaded bolt, it is proposed that the opening contour of the second opening is non-circular. The invention further relates to a combination of a bolt ( 4 ) having a cross-sectional area with a nut ( 10 ).

First claim

The invention claimed is:

1. A nut comprising:
a first part having a first through opening,
a second part having a second opening, said second opening having an opening contour,
the second part seats within the opening of the first part and the first and second parts being connected to one another so as to be rotatable relative to one another about a rotational axis which passes through the openings and the openings being aligned with one another,
the first opening having a profile on an inner face which extends in a peripheral direction and is interrupted in the peripheral direction,
the opening contour of the second part being non-circular,
the second part is rotatable relative to the first part about the axis of rotation in a limited angular range,
a biasing member engaging the first and second parts to preload the first and second parts into an untwisted position;
wherein one of the parts secures the parts together into a twisted position in a positive-fit manner, and action takes place on said part that secures the parts together into the twisted position in order to enable the parts to move to the untwisted position.

2. The nut according to claim 1 , wherein an extent of the second part in the direction of the rotational axis is shorter than an extent of the first part.

3. The nut according to claim 1 , wherein the twisted position is detent-locked.

4. The nut according to claim 1 , wherein the part that secures the parts together into the twisted position includes a spring loaded pin which engages with the other part.

5. The nut according to claim 1 , wherein the biasing member is a spring.

6. A nut comprising:
a first part having a first through opening,
a second part having a second opening, said second opening having an opening contour,
the second part seats within the opening of the first part and the first and second parts being connected to one another so as to be rotatable relative to one another about a rotational axis which passes through the openings and the openings being aligned with one another,
the first opening having a profile on an inner face which extends in a peripheral direction and is interrupted in the peripheral direction,
the opening contour of the second part being non-circular,
the second part is rotatable relative to the first part about the axis of rotation in a limited angular range,
wherein one of the parts secures the parts together into a twisted position in a positive-fit manner, and action takes place on said part that secures the parts together into the twisted position in order to enable the parts to move to an untwisted position, wherein the twisted position is detent-locked, and
a release part movable relative to the first and/or second part and capable of releasing the twisted position.

7. The nut according to claim 6 , wherein the release part is activated transversely with respect to the direction of extent of the rotational axis, or by rotation about the rotational axis.

8. A nut comprising:
a first part having a first through opening,
a second part having a second opening, said second opening having an opening contour,
the second part seats within the opening of the first part and the first and second parts being connected to one another so as to be rotatable relative to one another about a rotational axis which passes through the openings and the openings being aligned with one another,
the first opening having a profile on an inner face which extends in a peripheral direction and is interrupted in the peripheral direction, the profile is one or a plurality of thread turns,
the opening contour of the second part being non-circular,
the second part is rotatable relative to the first part about the axis of rotation in a limited angular range,
wherein one of the parts secures the parts together into a twisted position in a positive-fit manner, and action takes place on said part that secures the parts together into the twisted position in order to enable the parts to move to an untwisted position.

9. The nut according to claim 8 , wherein the one or plurality of thread turns are in the form of a left-hand thread.

10. A combination comprising:
a bolt having a length and a cross-sectional area; and
a nut having a first part having a first opening, said first opening having an inner profile, the nut having a second part having a second opening, said second opening having an opening contour,
the second part seats within the opening of the first part and the parts being connected to one another so as to be rotatable relative to one another about a rotational axis of the nut, and
the openings being in alignment, and
the cross-sectional area of the bolt having, at least in places, a contour over the length of the bolt which matches the opening contour of the second opening such that the bolt is insertable into the second opening but is not rotatable therein, wherein the bolt has initially in the direction in which the nut is fitted, an insertion portion which is profile-free, the insertion portion having an axial extent which corresponds to an axial extent of the second part.

11. A nut comprising:
a first part having a first through opening,
a second part having a second through opening having an opening contour,
the second part seats within the opening of the first part and the first and second parts being connected to one another so as to be rotatable relative to one another about a rotational axis which passes through the openings and the openings being aligned with one another,
the first opening having a profile on an inner face which extends in a peripheral direction and is interrupted in the peripheral direction,
the opening contour of the second part being non-circular,
the second part is rotatable relative to the first part about the axis of rotation in a limited angular range,
wherein one of the parts secures the parts together into a twisted position in a positive-fit manner, and action takes place on said part that secures the parts together into the twisted position in order to enable the parts to move to an untwisted position.

12. A nut comprising:
a first part having a first through opening,
a second part having a second opening, said second opening having an opening contour,
the second part seats within the opening of the first part and the first and second parts being connected to one another so as to be rotatable relative to one another about a rotational axis which passes through the openings and the openings being aligned with one another,
the first opening having a profile on an inner face which extends in a peripheral direction and is interrupted in the peripheral direction, the profile is one or a plurality of thread turns and one or a plurality of unthreaded portions,
the opening contour of the second part being non-circular,
the second part is rotatable relative to the first part about the axis of rotation in a limited angular range,
wherein one of the parts secures the parts together into a twisted position in a positive-fit manner, and action takes place on said part that secures the parts together into the twisted position in order to enable the parts to move to an untwisted position.

13. A combination comprising:
a nut having a first part having a first through opening, a second part having a second through opening, said second opening having an opening contour, the second part seats within the opening of the first part and the first and second parts being connected to one another so as to be rotatable relative to one another about a rotational axis which passes through the openings and the openings being aligned with one another, the f
