Abstract
A massage unit includes a treatment member; an arm that supports the treatment member; a drive shaft that supports the arm and causes the treatment member to approach and be separated with respect to a treatment target site; a movable portion that causes the treatment member to be operable in a direction of being separated from the treatment target site when the treatment member comes into contact with the treatment target site by a force equal to or greater than predetermined strength; and biasing means for biasing the treatment member in an approaching direction.
Claims24
A massage unit comprising:
- a treatment member;
- an arm that supports the treatment member;
- a drive shaft that supports the arm and causes the treatment member to approach and be separated with respect to a treatment target site;
- a movable portion that causes the treatment member to be operable in a direction of being separated from the treatment target site when the treatment member comes into contact with the treatment target site by a force equal to or greater than predetermined strength;
- and
- biasing means for biasing the treatment member in an approaching direction.
A massage unit comprising:
- a treatment member;
- an arm that supports the treatment member;
- a drive shaft that supports the arm and causes the treatment member to approach and be separated with respect to a treatment target site;
- a motor that drives the drive shaft to rotate;
- a control unit that controls driving of the motor;
- and
- a sensor configured to detect a plurality of levels regarding a rotational speed of the motor,
- wherein data of an aimed rotational speed of the motor corresponding to each level is stored in storage means of the control unit, and
- wherein when the sensor detects that the rotational speed of the motor falls from one level to a different level due to a change of a load from the treatment target site, the control unit newly sets an aimed rotational speed corresponding to the different level and performs controlling so as to cause the rotational speed of the motor to fall.
A massage machine comprising:
- a treatment member;
- an arm that supports the treatment member;
- a drive shaft that supports the arm and causes the treatment member to approach and be separated with respect to a treatment target site;
- a motor that drives the drive shaft to rotate;
- an air cell that expands so as to cause the treatment member and the treatment target site to approach each other;
- an air supply/discharge device that supplies and discharges air with respect to the air cell;
- a control unit that controls driving of the motor and the air supply/discharge device;
- and
- a sensor that directly or indirectly detects a load applied from the treatment target site to the treatment member,
- wherein when the sensor detects that the load increases or decreases to a predetermined value, the control unit causes the air supply/discharge device to discharge or supply air.
A massage machine comprising:
- a massage unit that includes a treatment member, an arm that supports the treatment member, a drive shaft that supports the arm and causes the treatment member to approach and be separated with respect to a treatment target site, a motor that drives the drive shaft to rotate, and an air cell that is able to expand toward the treatment member,
- wherein the massage unit is movable along a user in a height direction.
