Abstract

A haircutter ( 1 ) comprises a blade head ( 2 ), a grip, ( 10 ) and a haircutting blade ( 4 ) comprising a cutting edge ( 14 ) accommodated in the blade head ( 2 ). The blade head ( 2 ) comprises two blade head sections ( 201, 202 ) removably coupled to one another by means of a blocking device ( 200 ). The blocking device ( 200 ) comprises a locking mechanism ( 203 ) operable by an operating member ( 204 ). The operating member ( 204 ) is provided by at least part of the grip ( 10 ). Actuating the operating member ( 204 ) causes the locking mechanism ( 203 ) to shift from an operating position to an off position, to allow releasing the coupled blade head sections ( 201, 202 ) from one another.

Claims (27)

1 . A haircutter for trimming and styling hair of the head, comprising:

a blade head and a grip laterally disposed on the blade head, wherein a longitudinal face of the blade head comprises a working section disposed thereat which is recessed from an alignment line of the longitudinal face, and

wherein a haircutting blade comprising a cutting edge is accommodated and disposed in the blade head, so that the cutting edge is at least partially exposed in the working section and not protruding beyond the alignment line, wherein the blade head comprises a first blade head section and a second blade head section removably coupled to one another by means of at least one blocking device,

wherein the blocking device comprises at least one locking mechanism operated by an operating member, and wherein the operating member comprises at least part of the grip, and wherein actuating the operating member causes the locking mechanism to shift at least from an operating position to a release position, to allow releasing the coupled first and second blade head sections from one another, and

wherein the locking mechanism comprises a safety member, which is locked by means of the operating member to the second blade head section so as to assume the operating position, and which, in the operating position, extends at least partially at least from the first blade head section to the second blade head section, the first blade head section comprises a first blade head section through hole through which the safety member extends, so that an end of the safety member is connected with the grip, and another end of the safety member extends into a second blade head section through hole in the second blade head section.

2 . The haircutter according to claim 1 , wherein actuating the operating member causes the locking mechanism to shift from the release position to the operating position, to couple the blade head sections to one another.

3 . The haircutter according to claim 1 , wherein the locking mechanism is operated by means of a rotary motion of the operating member.

4 . The haircutter according to claim 1 , wherein the operating member is provided by an elongated part section of the grip.

5 . The haircutter according to claim 4 wherein the operating member is provided by the grip itself.

6 . The haircutter according to claim 1 , wherein the locking mechanism is configured to secure the second blade head section in a force fit to the first blade head section.

7 . The haircutter according to claim 1 , wherein the locking mechanism is configured to secure the second blade head section in a form fit to the first blade head section.

8 . The haircutter according to claim 1 wherein the locking mechanism is configured to move the second blade head section to the operating position in a linear movement with respect to the first blade head section.

9 . The haircutter according to claim 1 wherein the locking mechanism is configured to move the second blade head section to the operating position parallel to the plane of the first blade head section.

10 . The haircutter according to claim 1 wherein operational attachment of the grip to the first blade head section causes the locking mechanism to simultaneously fix the second blade head section to the first blade head section.

11 . The haircutter according to claim 1 wherein for releasing the second blade head section from the first blade head section, the safety member is released from the second blade head section by means of the operating member.

12 . The haircutter according to claim 1 , wherein the safety member comprises a threaded portion, which is screwed at least into the second blade head section by means of the operating member.

13 . The haircutter according to claim 1 , wherein the safety member is non-rotatably connected with the operating member.

14 . The haircutter according to claim 1 , wherein the safety member is non-rotatably connected with the grip.

15 . The haircutter according to claim 1 , wherein the grip is removably attached to the first blade head section by means of the safety member.

16 . The haircutter according to claim 1 , wherein the grip is removably attached to the second blade head section by means of the safety member.

17 . The haircutter according to claim 1 , wherein the first blade head section through hole is configured unthreaded and/or showing oversize in relation to the other end of the safety member, so that the other end of the safety member is passed through the first blade head section through hole without any screwing motion.

18 . The haircutter according to claim 1 , wherein the safety member comprises a threaded portion at least in sections.

19 . The haircutter according to claim 12 , wherein at least sections of the threaded portion of the safety member are coaxially disposed in the grip.

20 . The haircutter according to claim 1 , wherein the locking mechanism clamps the second blade head section relative to the first blade head section.

21 . The haircutter according to claim 1 , wherein the blocking device comprises at least one biasing device, which is configured to urge the second blade head section away from the first blade head section by means of spring force.

22 . The haircutter according to claim 1 , wherein the blocking device comprises a form grip device including a form grip member in the first blade head section, and a form grip member in the second blade head section, and wherein the form grip members of the first and the second blade head members are clamped to one another by transferring the locking mechanism to the operating position, so that the first and second blade head sections are locked to one another in a form fit.

23 . The haircutter according to claim 22 , comprising an adjusting device for aligning the haircutting blade in the blade head, wherein the adjusting device comprises an adjusting unit in at least partial engagement in a recess in the haircutting blade, and wherein the adjusting unit is provided by one of the form grip members.
