Abstract

The invention provides a hair removing apparatus having a body hair treatment head removing a body hair by shaving the body hair, depilating the body hair or cutting the body hair, and a main body grip held by a hand, and in which the body hair treatment head being rotatably coupled to the main body grip in such a manner that the body hair treatment head is freely oscillated with respect to the main body grip. In this structure, the hair removing apparatus is provided with a weight applying means for applying a force opposing to a force by which the body hair treatment head is oscillated by its own weight of the body hair treatment head around a center of rotation of the body hair treatment head.

Claims

1. A hair removing apparatus comprising:

a body hair treatment head removing a body hair, the body hair treatment head including two opposing longitudinal sides, two opposing lateral sides, and a first engagement member;

a main body grip held by a hand;

the body hair treatment head being rotatably coupled to the main body grip in such a manner that the body hair treatment head is freely oscillated with respect to the main body, grip;

a support member provided in the main body grip;

a rotation support portion provided at the support member; and

a weight system that applies a force opposing to an oscillating force by the weight of the body hair treatment head around a center of rotation of the body hair treatment head,

the weight system comprising a weight member provided on at least one of the opposite lateral sides of the body hair treatment head,

wherein the weight member includes a link portion rotatably supported portion,

a weight provided at one end of the weight member, and

a second engagement member provided at the other end of the weight member, the second engagement member engaging with the first engagement member of the body hair treatment head.

2. A hair removing apparatus as claimed in claim 1, wherein the weight system is installed to a longitudinal main body grip side.

3. A hair removing apparatus as claimed in claim 1, wherein the weight member is installed rotatably to a longitudinal main body grip side, the weight is provided in one side of the weight member with respect to a center of rotation of the weight member and the other side is coupled to the body hair treatment head.

4. A hair removing apparatus as claimed in claim 1, wherein the weight member is provided in a side portion of the body hair treatment head in a direction orthogonal to a direction in which the body hair treatment head is oscillated.

5. A hair removing apparatus as claimed in claim 1, wherein the body hair treatment head side is set to an upper side and the main body grip side is set to a lower side, and the weight member is provided in a lower side of the body hair treatment head.

6. A hair removing apparatus as claimed in claim 1, wherein a force of rotation moment applied so as to oppose to a moment of rotation of the body hair treatment head by the weight member is made equal to or smaller than a force of rotation moment generated by the body hair treatment head around a center of rotation of the body hair treatment head.

7. A hair removing apparatus as claimed in claim 1, wherein the weight member is provided in the main body grip side, and a force applied from the weight member is transmitted via a link.

8. A hair removing apparatus as claimed in claim 1, wherein the body hair treatment head is driven by a motor for removing hair.

9. A hair removing apparatus as claimed in claim 1, wherein the hair removing apparatus is constituted by an electric shaver, the body hair treatment head is constituted by a shaving head having a blade comprising an outer blade for cutting the hair and an inner blade brought into inside contact with the outer blade so as to reciprocate, the shaving head is provided with a rotating shaft support portion of the shaving head in an end portion in the reciprocating direction of the inner blade, and a rotating shaft support portion of the weight member is provided in a support table of the main body grip.

10. A hair removing apparatus as claimed in claim 1, wherein a portion coupling the weight member to the body hair treatment head is provided in an opposite side to a rotation support point of the body hair treatment head, with respect to a gravity point of the body hair treatment head.

11. A hair removing apparatus as claimed in claim 1, wherein the first engagement member is a projection and the second engagement member is a long groove.

12. A hair removing apparatus as claimed in claim 1, wherein the first engagement member is a long groove and the second engagement member is a projection.

13. A hair removing apparatus as claimed in claim 1, wherein the first engagement member is a projection and the second engagement member is a long hole.

14. A hair removing apparatus as claimed in claim 1, wherein the first engagement member is a long hole and the second engagement member is a projection.
