Abstract

A gap between a main body grip portion and a head portion is reduced while securing a tiltable range of the head portion with respect to the main body grip portion. A hair cutting device includes the head portion provided at its upper end surface with a blade head, and the main body grip portion which supports the head portion such that the head portion can vertically float and tilt. A lower portion of the head portion is accommodated in an opened space formed in an upper portion of the main body grip portion, the head portion includes a neck portion whose lower side width in the tilting direction is wider than an upper side width, the neck portion is located at a portion of an opening formed in an upper end surface of the main body grip portion.

Claims

1. A hair cutting device comprising:

a head portion provided at an upper end surface of the hair cutting device with a blade head for epilating hair, and

a main body grip portion which supports the head portion in a manner that the head portion can vertically float and tilt, wherein

a lower portion of the head portion is accommodated in an opened space formed in an upper portion of the main body grip portion, wherein

the head portion is supported in the opened space such that the head portion can vertically float and tilt, and wherein

the lower portion of the head portion includes;

a neck portion having a tapered lower side width movable in the tilting direction that is wider than an upper side width of the neck portion such that the tapered lower side width is located inside of and facing an edge of an opening formed in an upper end surface of the main body grip portion, and

two left and right shaft-bushing portions, each left and right shaft-bushing portion being provided at one of a front surface and a back surface of the head portion and below the neck portion to permit vertical floating and tilting of the head portion, each of the two shaft-bushing portions being configured to rotate about a rotational axis of tilting of the head portion and the rotational axis being provided below the edge of the opening formed in the upper end surface of the main body grip portion.

2. The hair cutting device according to claim 1, wherein the lower portion of the head portion located lower than the neck portion has a width in the tilting direction smaller than the neck portion.

3. The hair cutting device according to claim 1, wherein

the head portion is supported such that the head portion can laterally tilt, wherein

an annular member is mounted on an outer surface of the head portion at a position lower than the neck portion, wherein

the two left and right shaft-bushing portions respectively provided on a front surface and a back surface of the annular member are supported by a bearing formed on an inner surface of the opened space of the main body grip portion such that the two left and right shaft-bushing portions can turn and vertically move, and wherein

spring receivers provided on left and right ends of the annular member receive a push-up spring which biases the head portion upward.

4. The hair cutting device according to claim 3, wherein the annular member is made of a material that is different from material of a hull of the head portion and a hull of the main body grip portion, the annular member is configured as a slide guide member which comes into slide contact with the inner surface of the opened space of the main body grip portion and guides the motion of the head portion with respect to the main body grip portion.

5. The hair cutting device according to claim 2, wherein

the head portion is supported such that the head portion can laterally tilt, wherein

an annular member is mounted on an outer surface of the head portion at a position lower than the neck portion, wherein

the two left and right shaft-bushing portions respectively provided on a front surface and a back surface of the annular member are supported by a bearing formed on an inner surface of the opened space of the main body grip portion such that the two left and right shaft portions can turn and vertically move, and wherein

spring receivers provided on left and right ends of the annular member receive a push-up spring which biases the head portion upward.

6. The hair cutting device according to claim 5, wherein the annular member is made of a material that is different from material of a hull of the head portion and a hull of the main body grip portion, the annular member is configured as a slide guide member which comes into slide contact with an inner surface of the opened space of the main body grip portion and guides the motion of the head portion with respect to the main body grip portion.

7. A hair cutting device comprising:

a head portion provided at an upper end surface of the hair cutting device with a blade head for epilating hair, and

a main body grip portion which supports the head portion in a manner that the head portion can vertically float and tilt, wherein

a lower portion of the head portion is accommodated in an opened space formed in an upper portion of the main body grip portion, wherein

the head portion is supported in the opened space such that the head portion can vertically float and laterally tilt, and wherein

the lower portion of the head portion includes;

a neck portion having a tapered lower side width in the tilting direction that is wider than an upper side width such that the tapered lower side width is located inside of and facing an edge of an opening formed in an upper end surface of the main body grip portion, and

an annular member mounted on an outer surface of the lower portion of the head portion at a position lower than the neck portion, the annular member being operatively connected to the lower portion of the head portion by at least one base which projects from the lower portion of the head portion, wherein

the annular member includes at least two left and right shaft-bushing portions, each left and right shaft-bushing portion being provided on one of a front surface and a back surface of the annular member, respectively, wherein

the at least two left and right shaft-bushing portions are supported by a bearing formed on an inner surface of the opened space of the main body grip portion such that the at least two left and right shaft-bushing portions can turn and vertically move, and wherein

spring receivers provided on left and right ends of the annular member receive a push-up spring which biases the head portion upward.
