Abstract
An apparatus for adjusting a distance between first and second elements, comprising a first rotation member (200) rotatable between first and second stop positions and a second rotation member (300), wherein rotation of the first member between the first and second stop positions comprises a first rotation stage in which the first rotation member rotates through a first rotation angle and a second rotation stage in which the first rotation member is configured to engage with the second rotation member to rotate the second rotation member through a second rotation angle.
Claims15
A grooming device comprising first and second elements and an adjustment apparatus for adjusting a distance between said first and second elements, said adjustment apparatus comprising:
- a first rotation member arranged for rotation about an axis;
- a second rotation member coaxially arranged with the first rotation member for mutual rotation relative to each other about said axis;
- and
- at least one end stop positioned for determining a range of rotation of the first and second rotation members, said range of rotation extending from a first stop position to a second stop position;
- said first and second rotation members being adapted to cooperate with the at least one end stop such that:
- rotation of the first rotation member away from the first stop position in a first direction will lead to engagement with and driving of the second rotation member until rotation of both the first and second members is stopped at the second stop position by the at least one end stop;
- and
- rotation of the first rotation member away from the second stop position in a second direction opposite to the first direction will lead to re-engagement with and driving of the second rotation member until rotation of both the first and second members is stopped at the first stop position by the at least one end stop;
- said first rotation member being adapted for coupling to at least one of the first and second elements to adjust said distance in response to rotary motion of said first rotation member.
A grooming device comprising a comb element, a hair cutting element, and an adjustment apparatus for adjusting a distance between said comb element and said hair cutting element, said adjustment apparatus comprising:
- a first rotation member arranged for rotation about an axis;
- a drive mechanism coupled to the first rotation member and to at least one of the comb element and the hair cutting element for adjusting the distance between said elements in response to rotatory movement of the first rotation member;
- a second rotation member coaxially arranged with the first rotation member for mutual rotation relative to each other about said axis;
- and
- at least one end stop positioned for determining a range of rotation of the first and second rotation members, said range of rotation extending from a first stop position to a second stop position;
- said first and second rotation members being adapted to cooperate with the at least one end stop such that;
- rotation of the first rotation member away from the first stop position in a first direction will lead to engagement with and driving of the second rotation member until rotation of both the first and second members is stopped at the second stop position by the at least one end stop;
- and
- rotation of the first rotation member away from the second stop position in a second direction opposite to the first direction will lead to re-engagement with and driving of the second rotation member until rotation of both the first and second members is stopped at the first stop position by the at least one end stop.
A method of adjusting a distance between first and second elements of a grooming device over a range corresponding to a range of rotation of the first and second coaxially, arranged rotation members, said range of rotation being determined by at least one end stop and extending angularly from a first stop position to a second stop position said method comprising:
- moving the first element relative to the second element in a first direction by rotating the first rotation member away from the first stop position in a first direction to lead to engagement with and driving of the second rotation member until
- rotation of both the first and second rotation members is stopped at the second stop position by the at least one end stop;
- and
- moving the first element relative to the second element in a second direction by rotating the first rotation member away from the second stop position in a second direction to lead to re-engagement with and driving of the second rotation member until rotation of both the first and second rotation members is stopped at the first stop position by the at least one end stop.
