DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
Fig.1 (a) (b) shows schematic structure of the massage machine of this embodiment. The massage machine 10 of this embodiment is for the leg which supports the body part (in this embodiment leg K in this embodiment) which becomes a pair in the user's body independently in the two accommodating parts 11 which make concave shape. A total of two support portions 12 are provided.

  The base portion 13 constituting the leg support portion 12 is supported by coil springs 14 provided on the left and right wall portions 11a of the two accommodating portions 11 so as to be movable on substantially the same axis L in the left-right direction. A support main body portion 15 constituting the leg support portion 12 is fixed to the upper portion of the base portion 13, and the support main body portion 15 is formed to have a concave shape that protrudes downward. Air bags 16 that can be inflated and contracted are provided on the left and right inner wall surfaces 15 a of the support main body 15. The airbag 16 is inflated and contracted by a control unit 18 that controls driving of the air pump 17.

  On the other hand, on the lower side of the leg support portion 12, a linear motor 20 is provided as a swing driving means for swinging the leg support portion 12 in the left-right direction. The linear motor 20 is controlled by the control unit 18 and includes an electromagnet 21 fixed to the bottom 11b of the housing unit 11 and two magnets 22a and 22b having different magnetic poles.

  The electromagnet 21 includes a core 21a and a coil 21b wound around the core 21a. Power supply from a power source (not shown) to the coil 21b is controlled by the control unit 18, and the upper surface side is based on the power supply. Magnetic poles are formed on the surface. The magnets 22 a and 22 b face the electromagnet 21 in the vertical direction (up and down direction) and are arranged in parallel in the left and right direction of the lower surface of the base portion 13. For this reason, when power is supplied via the control unit 18 by the coil 21b of the electromagnet 21, the electromagnet 21 is magnetized and attracted by one of the two magnets 22a and 22b and repulsive by the other side. And the magnets 22a and 22b are moved in the left-right direction. As a result, the leg support 12 provided with the magnets 22a and 22b is oscillated (translated) in the left-right direction.

  In the massage machine 10 configured as described above, for example, a plurality of massage courses for performing a predetermined operation are set, and a swing operation of 2 Hz or more for a certain period is performed in at least one massage course. Here, this inventor performed evaluation experiment about the difference of the massage effect obtained in various massage operation | movement. In addition, the massage operation only by the grip / release operation (expansion / contraction operation) by the airbag 16, the massage operation only by the swing operation for swinging the leg support portion 12 in the left-right direction, the above-described grip / release operation and swing operation. An evaluation experiment is conducted on the massage effect of the three types of massage operations of the combination operation. In addition, with regard to the swinging operation, an experiment was performed on four types of operating frequencies of 2 Hz, 3 Hz, 4 Hz, and 6 Hz. 3 (a) and 3 (b) show the experimental results of each massage operation, and FIG. 3 (a) shows the difference in massage effect for the “feeling of comfort” by each massage operation. b) shows the difference in the massage effect with respect to “feeling of relaxation” by each massage operation.

  In addition to the above-described evaluation experiment, the present inventor has also separately conducted an evaluation experiment on the difference in massage effect obtained by the difference in swinging motion (see FIG. 4). Specifically, it is an evaluation experiment for a difference in “feeling of unraveling” which is a massage effect when changing from 1 Hz to 6 Hz in 1 Hz increments.

  As can be seen from FIG. 4, the difference between 1 Hz and 2 Hz is the largest, and it can be seen that a good massage effect can be obtained in a relatively high-speed rocking motion of 2 Hz or more. Further, as can be seen from FIG. 3A, by setting the oscillation frequency of the oscillation operation to 2 Hz or more, a massage effect higher than the massage effect only by the gripping / release operation can be obtained. Furthermore, as can be seen from FIGS. 3A and 3B, a more suitable massage effect can be obtained by a combined operation of the swinging operation and the gripping / opening operation. Further, by performing gripping / release operations in addition to swinging operations, it is possible to diversify the massage operations, thereby contributing to the maintenance of the user's motivation.

  Further, in the massage machine 10 configured as described above, the user's leg K is gripped by the inflation operation of the airbag 16 as shown in FIGS. The control unit 18 controls the gripping state and the open state in which the user's leg K is opened by the contraction operation of the airbag 16 as appropriate. Here, for example, when performing a swinging operation with a relatively low swinging frequency of 1 Hz or less, the swinging operation is performed with the airbag 16 contracted and the leg K opened. With such a configuration, when the user swings at a low frequency of about 1 Hz or less, if the user's leg K is gripped, the swing of the swinging motion can be reliably transmitted to the body. Compared with the open state, the swinging state of the leg K tends to deteriorate. For this reason, when the operation has a low oscillating frequency as described above, the entire leg portion K of the user sways in the inner wall surface portion 15a of the support main body portion 15 by operating in an open state. K's thigh, knee circumference and lower leg massage can be performed.

  On the other hand, when the swinging frequency of the leg support portion 12 is a relatively high speed swinging operation of 2 Hz or more, the air pump 17 is controlled by the control unit 18 to inflate the airbag 16 so that the leg K is moved. The frequency of the swinging operation is changed in the gripped state. This is because when the gripping state is set, the swinging motion of the leg support 12 is reliably transmitted, and a massage centered on the toe (ankle) on the gripping side is performed. When the airbag 16 is contracted and the leg K is opened, when the swinging operation is performed at a relatively high speed with a swing frequency of 2H or more, the leg K cannot follow the swinging motion, and the leg The hitting operation in which the airbag 16 in the contracted state contacts the side surface of the portion K can be performed.

  In addition, since each support main body 15 is configured to be swingable in the reverse direction on the same axis L in the left-right direction, the support main body 15 (leg support 12) is swung so as to be opposite to each other. By operating, the movement (vibration) of the massage machine 10 due to the swinging operation can be suppressed. In addition, since the coil spring 14 is configured to resonate, a sufficient swinging operation can be realized even if the power supplied to the coil 21b constituting the electromagnet 21 is suppressed.

Next, characteristic effects of the present embodiment will be described.
(1) The leg support portion 12 includes a plurality of support body portions 15 that independently support a pair of body parts (leg portions K) within the user's body. 12, each support main body 15 is configured to be swingable in different directions by the linear motor 20. The control unit 18 is configured such that the swing frequency of the swing operation of each support body 15 by the linear motor 20 can be changed to 2 Hz or more. In this way, by swinging so that the swing frequency is 2 Hz or more, it is possible to give a suitable massage effect that further stimulates the muscles of the leg K of the user and loosens the muscles. 3 (a) (b) and FIG. 4).

  (2) Further, since each of the two support main body portions 15 provided in the leg support portion 12 is configured to be swingable in different directions, diversification of the swing operation as a massage operation can be achieved. Therefore, it can contribute to a user's motivation maintenance.

  (3) The support main body portions 15 of the leg support portions 12 are swung on the same axis L, and the linear motor 20 is moved by the control portion 18 so that the swing directions of the support main body portions 15 are opposite to each other. Be controlled. In other words, by reversing the swing direction of each support main body 15 that can swing on the same axis L, the acceleration that can occur in the entire massage machine 10 can be offset, and vibration and noise caused by the vibration Can be suppressed.

  (4) The leg support portion 12 is provided with an airbag 16 that repeatedly holds and releases at least a portion of the user's body (leg portion K). For this reason, in addition to the massage effect by rocking | fluctuation operation | movement, the massage effect by the expansion / contraction operation | movement of the airbag 16 can be provided. Further, it is possible to increase the variation of the operation by combining the swinging operation with the gripping and releasing operation.

  (5) The leg support portion 12 is provided with a coil spring 14 for resonating each support body portion 15 during the swinging operation. The swing operation of the leg support 12 (each support main body 15) by the linear motor 20 can be easily performed.
