Abstract

A locking ring with a center axis includes a first set of locking elements which extend radially from a first radial distance from the center axis of the locking ring to a second radial distance from the center axis, and which are arranged in a plurality of first groups including at least one locking element each, where the first groups are arranged in a circumferentially equidistant manner around the center axis, and a second set of locking elements, which extend radially from the first radial distance from the central axis to a third radial distance from the central axis, where the third radial distance is smaller than the second radial distance, and which are arranged in a plurality of second groups including at least one further locking element each. A rear view device for a vehicle and a motor vehicle with the rear view device are also described.

Claims18

Dependent claims

A locking ring with a center axis for a rear view device, comprising:

a first set of locking elements which extend radially from a first radial distance from the center axis to a second radial distance from the center axis, and which are arranged in a plurality of first groups comprising at least one locking element each, the plurality of first groups being arranged in a circumferentially equidistant manner around the center axis;
a second set of locking elements which extend radially from the first radial distance from the central axis to a third radial distance from the central axis, the third radial distance being smaller than the second radial distance, and the second set of locking elements being arranged in a plurality of second groups comprising at least one further locking element each, the plurality of second groups being arranged in a circumferentially equidistant manner around the locking ring;
and
a third set of locking elements which extend radially from the second radial distance from the center axis to the third radial distance from the center axis, which are arranged in a circumferentially equidistant manner around the locking ring, and which have a smaller axial extent than the locking elements of the first set of locking elements and the second set of locking elements,
wherein the plurality of first groups and the plurality of second groups are arranged alternately gapless.

2 more elements

A rear view device for a vehicle, comprising:

a base portion comprising a first locking ring having a center axis;
and
a head portion comprising a second locking ring having a center axis, and being pivotable relative to the base portion around a pivot axis,
wherein the center axis of the first locking ring is arranged coaxially with the pivot axis and the center axis of the second locking ring is arranged coaxially with the pivot axis, and at least one of the first and the second locking rings comprises:
a first set of locking elements which extend radially from a first radial distance from the center axis to a second radial distance from the center axis, and which are arranged in a plurality of first groups comprising at least one locking element each, the plurality of first groups being arranged in a circumferentially equidistant manner around the center axis;
and
a second set of locking elements which extend radially from the first radial distance from the center axis to a third radial distance from the center axis, the third radial distance being smaller than the second radial distance, and the second set of locking elements being arranged in a plurality of second groups comprising at least one further locking element each, the plurality of second groups being arranged in a circumferentially equidistant manner around the locking ring,
the plurality of first groups and the plurality of second groups are arranged alternately gapless,
the first locking ring comprises first locking elements of the first set of locking elements and second locking elements of the second set of locking elements,
the second locking ring comprises third locking elements of the first set of locking elements which are complementary to the first locking elements of the first locking ring, and fourth locking elements of the second set of locking elements which are complementary to the second locking elements of the first locking ring,
the second locking ring further comprises fifth locking elements of a third set of locking element, and
in an operational position of the rear view device, the first locking elements are mutually engaged with the fifth locking elements.
