Massage head and massage apparatus using such a head
A casing defining an internal chamber having a skinfold formed therein when it is applied to a patient's skin, said fold coming into contact with the lower edges of the chamber. The chamber is defined by two lateral walls and by two transverse walls, at least one of said transverse walls being formed of a flap capable of having a pivoting motion, to induce the coming closer and the drawing away from each other of the lower edges of said transverse walls in contact with the skinfold. The flap is hinged in the vicinity of its upper end on the lateral walls. The pivoting of the flap is obtained by means of a geared motor fixedly assembled within said flap, and having its output shaft rotating a cam, received in a cam race fastened to one of the lateral walls of the internal chamber.
1. A massage head comprising a casing defining an internal chamber configured to have a skinfold formed therein when the massage head is applied to a patient's skin, said fold configured to come into contact with the lower edges of the chamber, said chamber being defined by two lateral walls and by two transverse walls, at least one of said transverse walls being formed of a flap capable of having a pivoting motion, to induce the coming closer and the drawing away from each other of the lower edges of said transverse walls configured to be in contact with the skinfold:
wherein said at least one flap is hinged in the vicinity of its upper end on the lateral walls; and
wherein the pivoting of the flap is obtained by means of a geared motor fixedly assembled within said flap, an output shaft of said geared-motor rotating a cam, received in a cam race rigidly attached to one of the lateral walls of the internal chamber.
2. The massage head of claim 1 , wherein the free lower edge of the flap(s) is coated with a material having a high friction coefficient.
3. The massage head of claim 1 , wherein a lateral wall opposite to that receiving the cam races receives an electronic board connected to a connector, accessible at the level of the upper end of said lateral wall.
4. The massage head of claim 1 , wherein said head is formed of two modules, provided with means capable of enabling to reversibly fasten them to each other.
5. The massage head of claim 1 , wherein said head receives a sealing shutter in the upper portion of the internal chamber defined in said head, said shutter being lodged in housings provided for this purpose.
6. The massage device of claim 1 , wherein the free lower edge of the flap(s) is coated with elastomer.
7. A massage device comprising:
a massage head comprising a casing defining an internal chamber configured to have a skinfold formed therein when the massage head is applied to a patient's skin, said fold configured to come into contact with the lower edges of the chamber, said chamber being defined by two lateral walls and by two transverse walls, at least one of said transverse walls being formed of a flap capable of having a pivoting motion, to induce the coming closer and the drawing away from each other of the lower edges of said transverse walls configured to be in contact with the skinfold: wherein said at least one flap is hinged in the vicinity of its upper end on the lateral walls; and wherein the pivoting of the flap is obtained by means of a geared motor fixedly assembled within said flap, an output shaft of said geared-motor rotating a cam, received in a cam race rigidly attached to one of the lateral walls of the internal chamber; and
an electric power source capable of actuating a motor actuating a reducer of the geared-motor.
8. The massage device of claim 7 , wherein said device comprises a vacuum or depression source associated with the massage head, and emerging into the massage head.
