Abstract
The invention is directed to a power driven hair clipper (HSM), comprising a drive mechanism provided in a housing (1) and a clipper head (S) equipped with a clipper comb (3) and a clipper blade (4, 82) and mounted on said housing (1) for pivotal motion about a pivot axis (Z), wherein the clipper comb (3) is in cooperating relationship with two clipper blades (4, 82), each being adapted to be coupled with a drive member (12) of the drive mechanism according to the pivot position of the clipper head (S) relative to the housing (1).
Claims55
A power driven hair clipper, comprising a drive mechanism provided in a housing (1) and a clipper head (S) comprising a clipper comb (3) in cooperating relationship with first and second clipper blades (4, 82), said clipper head being mounted on said housing (1) for selectable pivotal motion about a pivot axis between at least first and second pivoted positions, whereby alternately one of said first and second clipper blades (4, 82) is coupled with said drive mechanism according to the selected respective pivoted position of the clipper head (S) relative the housing (1), and
- wherein the clipper head is supported on the housing by pivot bearings formed by cooperating bearing elements (16, 17, 18, 19) relatively movable against the pressure of at least one spring element (28, 29).
A power driven hair clipper, comprising a drive mechanism provided in a housing (1) and a clipper head (S) comprising a clipper comb (3) in cooperating relationship with first and second clipper blades (4, 82), said clipper head being mounted on said housing (1) for selectable pivotal motion about a pivot axis between at least first and second pivoted positions, whereby alternately one of said first and second clipper blades (4, 82) is coupled with said drive mechanism according to the selected respective pivoted position of the clipper head (S) relative the housing (1),
- wherein the clipper head (S) is secured to a supporting element (5) mounted on the housing (1) for pivotal motion about the pivot axis, and
- wherein the clipper head (S) is releasably attached to the supporting element (5) by a locking device (9, 10).
A power driven hair clipper, comprising a drive mechanism provided in a housing (1) and a clipper head (S) comprising a clipper comb (3) in cooperating relationship with first and second clipper blades (4, 82), said clipper head being mounted on said housing (1) for selectable pivotal motion about a pivot axis between at least first and second pivoted positions, whereby alternately one of said first and second clipper blades (4, 82) is coupled with said drive mechanism according to the selected respective pivoted position of the clipper head (S) relative the housing (1),
- wherein the clipper comb (3) has two rows of cutting teeth (40, 41).
A power driven hair clipper, comprising a drive mechanism provided in a housing (1) and a clipper head (S) comprising a clipper comb (3) in cooperating relationship with first and second clipper blades (4, 82), said clipper head being mounted on said housing (1) for selectable pivotal motion about a pivot axis between at least first and second pivoted positions, whereby alternately one of said first and second clipper blades (4, 82) is coupled with said drive mechanism according to the selected respective pivoted position of the clipper head (S) relative the housing (1),
- wherein a pivot range of the clipper head (S) is determined by a detent device (RV), and wherein the detent device (RV) is formed by at least one notch (102) and one detent element (101) adapted to be biased by a detent spring element (100).
A power driven hair clipper, comprising
- a drive mechanism provided in a housing (1), and
- a clipper head (S) comprising a clipper comb (3) in cooperating relationship with first and second moving clipper blades (4, 82),
- wherein the clipper comb has two rows of cutting teeth along opposing edges of the comb, the first clipper blade being in cooperating relationship to a first said row of comb teeth, the second clipper blade being in cooperating relationship to a second said row of comb teeth,
- said clipper head being mounted on said housing (1) for selectable displacement between at least first and second operating positions,
- whereby in said first operating position said first clipper blade (4) is coupled with said drive mechanism and said second clipper blade is decoupled from said drive mechanism,
- and in said second operating position said second clipper blade (82) is coupled with said drive mechanism and said first clipper blade is decoupled from said drive mechanism.
A method of engaging one of a plurality of clipper blades of a power driven hair clipper selectively by a user, comprising the steps of
- providing a drive mechanism in a housing, and a clipper head comprising a clipper comb in cooperating relationship with first and second moving clipper blades,
- providing at least two rows of teeth on said clipper comb, said first row of comb teeth being in cooperating engagement with said first clipper blade and said second row of comb teeth being in cooperating engagement with said second clipper blade,
- mounting said clipper head for displacement on said housing,
- moving said clipper head relative the housing to a first operating position,
- coupling, in said first operating position, said first clipper blade with said drive mechanism and decoupling said second clipper blade from said drive mechanism, and then
- moving said clipper head relative the housing to a second operating position,
- decoupling, in said second operating position, said first clipper blade from said drive mechanism and coupling said second clipper blade with said drive mechanism,
- whereby a user can selectively choose said first and second operating positions.
