Abstract

PROBLEM TO BE SOLVED: To obtain massaging and spot pressing effects by freely moving a manual massaging device in all directions on the surface of a body. SOLUTION: The manual massaging device comprises a container having a circular opening and a semispherical recessed cavity section formed continuously from the opening, a main ball having an outside diameter smaller than the inside diameter of the opening, and a plurality of auxiliary balls which are interposed between the main ball and the internal surface of the cavity section to rotatably support the main ball. The device also comprises a lid which has a window and closes the opening of the container by partially exposing the rotatably supported main ball from the window.

DISCLOSURE OF THE INVENTION The present invention provides an instrument capable of effectively moving the body surface in all directions by a simple operation to effectively massage, and exerting acupressure effect by applying pressure. This is an issue.

[0004]

According to the present invention, a container having a circular opening and a hollow portion hemispherically recessed from the opening, a main ball having an outer diameter smaller than the inner diameter of the opening, and a main ball in the hollow portion are provided. Manual massage consisting of a plurality of auxiliary balls inserted between the main ball and the inner wall of the cavity for rotatably supporting it, and a lid closing the opening with a window exposing a part of the supported main ball To provide a container.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a sectional view showing a manual massager of the present invention, and FIG. 2 is a lower drawing. As shown in these figures, the hemispherical container 1 has a circular opening 7, and has a hollow portion 6 recessed from the opening 7 in a hemispherical shape.

The cavity 6 accommodates the main ball 3 having an outer diameter D2 smaller than the inner diameter D1 of the opening 7. A plurality of auxiliary balls 4 are inserted between the main ball 3 and the inner wall of the cavity 6, and the plurality of auxiliary balls 4 surround the main ball 3 and rotatably support the cavity 6 at substantially the center thereof.

The lid 2 has a circular disk-shaped window 2a, and the opening 7 is closed so that a part of the main ball 3 is exposed to the outside by a distance A from the window 2a. The window 2a has an inner diameter slightly smaller than the outer diameter of the main ball 3 so that the main ball 3 does not come out. In order to ensure a slight clearance (clearance) between the main ball 3 and the auxiliary ball 4 and the inner wall of the hollow portion 6 and to facilitate the rotation of the main ball 3, the lid 2 and the hemispherical container 1 are separated from each other. A ring-shaped spacer 1a having a thickness L is provided between
Is inserted.

The hemispherical container 1, the ring-shaped spacer 1a and the lid 2 are fixed to each other with an adhesive or a screw. The ring-shaped spacer 1a may be formed integrally with the hemispherical container 1 or the lid 2. The ring-shaped spacer 1 a has the same inner diameter as the opening 7. The edge of the window 2a is tapered so as to follow the shape of the main ball 3. The hemispherical container 1 has a column-shaped handle 5 standing on the top, and the tip of the handle 5 is processed into a hemispherical shape.

Here, the relationship between the inner diameter D1 of the opening 7, the outer diameter D2 of the main ball 3 and the outer diameter D3 of the auxiliary ball is D1 =
D2 + 2 × D3, and the thickness L of the ring-shaped spacer 1a is determined in consideration of the fact that the main ball smoothly rotates in the cavity 6 and a part of it protrudes from the window 2a by the distance A. It Specific numerical examples are as follows: D1 = 60 mm, D2 = 40 mm, D3 = 10 mm, L
= 2 mm, A = 16 mm, the diameter D4 of the handle 5 is 20 mm, and the length S is 90 m.
m. The number of auxiliary balls 4 accommodated in the cavity 6 is 31.

In this embodiment, as materials for the hemispherical container 1, the main ball 3, the auxiliary ball 4, the spacer 1a and the lid 2,
From the viewpoint of mechanical strength, weight, surface lubricity, and workability, polyacetal resin is adopted and manufactured by molding or machining. In this case, the thickness of the hemispherical container 1 is 3 mm and the plate thickness of the lid 2 is 2 mm.

The main ball 3 may be made of a slightly elastic material such as hard rubber. Further, although the container 1 having a hemispherical outer shape is used in this embodiment, the container 1 is not limited to this, and may have a rectangular parallelepiped shape, a cylindrical shape, a prismatic shape, or a semi-elliptical shape. The shape of the handle 5 may be T-shaped or L-shaped.

Next, the method of use will be described. When the user holds the handle 5 with his / her hand and moves the main ball 3 while closely contacting it with the surface of the body, the main ball 3 is freely rotated by the rotation and support action of the auxiliary ball 4 in the container 1. Even if a force is applied to the handle 5, the main ball 3 can be advanced in any direction without giving a frictional force to the surface of the body, and the muscles can be smoothly loosened with a desired force. Furthermore, by stopping and applying pressure, an effect similar to acupressure can be obtained. Further, the same acupressure effect can be obtained by using the top of the handle.

[0013]

According to the present invention, it is possible to provide a manual massaging device capable of freely moving the surface of the body in all directions for massage by simple operation and applying pressure to obtain the acupressure effect. You can
