Massage bead, a pair of shoes and cushion
View Patent ↗A massage bead includes a massage body and at least two sets of extension twisting spring assemblies (ETSAs) arranged below the massage body, each set of ETSAs including a twisting spring and an extension spring. An upper extension twisting arm of the extension spring is connected with the massage body. A lower extension twisting arm of the extension spring is connected with one upper of the twisting spring. The upper extension twisting arm and the extension spring that are arranged in a counterclockwise direction simultaneously relative to the massage body. When the massage body is under pressure, the ETSA is compressed and twisted to generate a rotational pushing force together for pushing the massage body to rotate in the clockwise direction or in the counterclockwise direction, and the pressure disappears so that the massage body and the ETSAs resets automatically when the energy is released.
1 . A massage bead, comprising a massage body, below which at least two sets of extension twisting spring assemblies (ETSAs) are arranged, wherein the massage body is mounted on an external supporting member through the ETSAs;
each set of the ETSAs comprises a twisting spring and an extension spring; each ETSA is located below the massage body and mounted on the external supporting member through the twisting spring, an upper extension twisting arm of the extension spring is connected with the massage body, and a lower extension twisting arm of the extension spring is connected with an upper end of the twisting spring; the upper extension twisting arm, the extension spring and the lower extension twisting arm connected with each other are arranged axially and in a tilted manner and in a clockwise direction or in a counterclockwise direction simultaneously relative to the massage body; and
when the massage body is under pressure, each ETSA is compressed and twisted to generate a rotational pushing force together for pushing the massage body to rotate in the clockwise direction or in the counterclockwise direction, and deformation energy is stored when each ETSA is compressed and twisted so that the massage body resets automatically when energy is released.
2 . The massage bead according to claim 1 , wherein two sets or more than two sets of the ETSAs are arranged uniformly in a circumferential direction around a center of the massage body or arranged below the massage body.
3 . The massage bead according to claim 1 , wherein the twisting springs are arranged below the massage body in a combined manner along a radial direction of the massage body; and
the upper end of the twisting spring is connected with the extension spring, and a lower end of the twisting spring is further provided with an extension arm, each of the extension arms of the twisting springs of the ETSAs being connected with each other.
4 . The massage bead according to claim 1 , wherein the massage body comprises a massage base and a massage structure, and the massage base and the massage structure are two independent structures or the massage base is integrated with the massage structure.
5 . The massage bead according to claim 4 , wherein the massage structure is arranged on an upper end surface of the massage base, and each upper extension twisting arm is connected to inner sides of the massage body, outer sides of the massage body, or/and to the inner sides and the outer sides of the massage base; and
each upper extension twisting arm is fixedly connected or/and non-fixedly connected with the massage body or the massage base.
6 . The massage bead according to claim 4 , wherein a shape of an end surface of the massage structure opposite to the massage base is a hemisphere, a semi-ellipse, a polyhedron, a figure, a symbol, a character, a letter or other preset shapes, or one or/and any combinations thereof.
7 . The massage bead according to claim 4 , wherein materials of the massage structure and the massage base are stone, wood, medicinal material, pure material, composite, or synthetic material, and any combinations thereof.
8 . The massage bead according to claim 1 , wherein a receiving portion corresponding to each of the ETSAs and the massage body is arranged on the external supporting member, so that after the massage body is rotated and pressed downward under a force, the massage bead is placed in the receiving portion or placed above the receiving portion and the twisting spring.
9 . A pair of shoes or a cushion, comprising the massage bead according to claim 1 .
