Abstract

A scalp massager has a main body provided on the rear end thereof with a grip portion, a base portion, a pair of supporting arms projecting laterally from the base portion and spaced from each other in the longitudinal direction of the base portion, a roller member rotatably mounted between the arms for rotation about an axis substantially parallel to the longitudinal axis of the base portion, the roller member being provided on the outer peripheral surface thereof with a multiplicity of scalp stimulating projections, and compression springs for resiliently biasing the roller member away from the grip portion. The user grips the grip portion and lightly presses the roller member onto his head, and moves the massager back and forth so that the roller member rolls on the scalp with the result that the projections stimulate blood vessels under the scalp so as to enhance the blood stream. The roller member, which is resiliently urged by the compression springs, can gently and uniformly contact the scalp so as to moderately stimulate the head without any risk for the scalp to be damaged.

Claims

1. A scalp massager comprising:

a main body having a base portion with a longitudinal axis and a grip portion rearwardly extending from said base portion with an axis inclined with respect to said longitudinal axis;

a pair of hollow supporting arms projecting forwardly and laterally from said base portion and spaced from each other in the longitudinal direction of said base portion, each arm having a slot;

a roller member rotatably mounted between said arms for rotation about an axis substantially parallel to said longitudinal axis of said base portion, said roller member being provided on the outer peripheral surface thereof with scalp stimulating projection means and said roller member being provided at each longitudinal end with a pin, said pins being slidable along and projecting through said slots, respectively, into said hollow arms; and

resilient means disposed within said hollow arms for resiliently biasing said roller member forwardly.

2. A scalp massager according to claim 1, wherein said roller member has a cylindrical form.

3. A scalp massager according to claim 1, wherein said axis about which said roller member rotates is inclined with respect to the longitudinal axis of said grip portion such as to facilitate the placement of said roller member on the head of the user who grips said grip portion.

4. A scalp massager according to claim 1, wherein said roller member has a barrel-like form.

5. A scalp massager according to claim 4, further comprising a permanent magnet disposed within said roller member.

6. A scalp massager according to claim 1, wherein a retaining pin is disposed within each of said hollow arms, and said resilient means includes a coiled compression spring loaded between said retaining pin and said pin of said roller member.

7. A scalp massager according to claim 6, wherein said coiled compression spring is disposed in a guide frame provided between said retaining portion in each arm and said pin on the adjacent end of the shaft of said roller member.

8. A scalp massager according to claim 1, wherein said projection means include a multiplicity of projections formed on the outer peripheral surface of said roller member.

9. A scalp massager according to claim 8, wherein each of said projections has a pyramidal form with a substantially square cross-section.
