  The massage apparatus 10A according to the present embodiment is mainly used for beauty, and specifically, used when performing massage on the user's stomach, face, neck, head, and the like. The massage device 10A is generally configured to include the grip portion 1, the massage head 5, the rotation biasing mechanism 6, and the like.

  As shown in FIG. 1, the grip portion 1 has a grip portion main body 2, an inner 3, an outer 4, and the like. The grip part main body 2 is a part gripped by the user when performing massage at the massage position. The grip portion main body 2 has a cylindrical shape, and thus a through hole 22 is formed inside. Further, a step portion 23 is formed on the outer periphery of the upper end portion (the end portion on the arrow X2 direction side in the drawing) of the grip portion main body 2.

  By the way, the massage apparatus 10A according to the present embodiment is configured to be able to store a cosmetic container (for example, an aerosol container) loaded with, for example, a cosmetic or the like in the grip portion main body 2. When a cosmetic container is attached to the massage apparatus 10A, the cosmetic can be discharged to the massage position in accordance with a massage operation described later. In the following description, for convenience of explanation and illustration, a case where a cosmetic container is not attached will be described as an example.

  The inner 3 is configured to include an inner main body 31, a flange portion 32, a mounting portion 33, and a nozzle portion 34. The inner main body 31 is generally shaped like a bottomed cylinder. A flange portion 32 and a mounting portion 33 are formed in the vicinity of the lower end portion (the end portion in the arrow X1 direction) of the inner main body 31.

  The mounting portion 33 is configured to be fitted into the through hole 22 of the grip portion main body 2. Further, when the mounting portion 33 is fitted into the grip portion main body 2, the hook portion 32 is inserted until it comes into contact with the upper side end portion (X2 direction side end portion, the peripheral edge portion of the through hole 22) of the grip portion main body 2. . The inner portion 3 is positioned with respect to the grip portion main body 2 by the flange portion 32 coming into contact with the upper end portion of the grip portion main body 2.

  In addition, a nozzle portion 34 is formed at an upper end portion (X2 direction side end portion) of the inner main body 31. The nozzle portion 34 has a small diameter with respect to the inner main body 31, and thus a stepped portion 37 is formed at the boundary portion between the nozzle portion 34 and the inner main body 31.

  As shown in FIG. 5, a hole 35 is formed in the nozzle portion 34. The hole 35 functions as a passage for cosmetics discharged from the cosmetic container when the cosmetic container is mounted.

  The outer 4 has a substantially cylindrical shape and is disposed so as to cover the inner 3. The outer 4 is configured to include an outer main body 41, a fixing portion 42, a head receiving portion 43, and an engagement pin 45.

  The inner diameter of the outer main body 41 is set larger than the outer diameter of the inner main body 31 described above. Therefore, a cylindrical gap 9 is formed between the inner surface of the outer main body 41 and the outer surface of the inner main body 31.

  The fixing portion 42 is formed at the lower end portion (the end portion on the X2 direction side) of the outer main body 41. The fixing portion 42 is fitted into the stepped portion 23 of the gripping portion main body 2, whereby the outer 4 is fixed to the gripping portion main body 2. At this time, the fixing portion 42 is fitted to the step portion 23 after the inner 3 described above is attached to the grip portion main body 2.

  A stepped portion 42 a is formed at the boundary of the outer main body 41 on the inner wall of the fixed portion 42. When the outer 4 is fixed to the grip portion main body 2, the stepped portion 42 a engages with the flange portion 32 of the inner 3 and presses it toward the grip portion main body 2. Therefore, by fixing the outer 4 to the grip portion main body 2, the inner 3 is also fixed to the grip portion main body 2.

  The head receiving portion 43 is formed at the upper end portion (end portion on the X1 direction side) of the outer main body 41. The head receiving portion 43 is accommodated such that a head portion 52 described later is movable (movable in the X1 and X2 directions).

  The engagement pin 4 (corresponding to the engagement member described in the claims) constitutes the rotation urging mechanism 6 and is disposed on the outer main body 41. The engagement pin 45 protrudes inward from the inner wall of the outer main body 41.

  The massage head 5 (corresponding to a head portion described in claims) is configured such that an outer cylindrical portion 51, a head portion 52, and an inner cylindrical portion 58 are integrally formed. In the present embodiment, the massage head 5 is made of TPU (thermoplastic polyurethane elastomer). This TPU has a characteristic that has both elasticity like rubber and toughness like hard plastic. The material of the massage head 5 is not limited to TPU, and various materials such as metal, wood, glass, stone, and rubber can be used as long as they have a predetermined hardness described later.

  The outer cylinder portion 51 is movably inserted between the inner 3 and the outer 4 described above. That is, as described above, the cylindrical gap 9 is formed between the inner surface of the outer main body 41 and the outer surface of the inner main body 31, but the outer cylindrical portion 51 is movable in this gap 9 (in the X1 and X2 directions). To be inserted). Therefore, the massage head 5 is guided by the inner 3 and the outer 4 and moves in the directions of arrows X1 and X2 in the figure. Further, a cam groove 55 </ b> A that constitutes a rotation urging mechanism 6 described later is formed on the surface of the outer cylindrical portion 51.

  The diameter of the head part 52 is set larger than the diameter of the outer cylinder part 51. The head portion 52 is movably mounted inside the head receiving portion 43 of the outer 4. The upper surface of the head portion 52 is a contact surface 53 that comes into contact with a massage position (user's skin) when performing massage using the massage device 10A.

  The contact surface 53 has a plurality of convex portions 54 and 56 (detailed in FIG. 4). In the present embodiment, convex portions 56 are formed at the center position of the circular contact surface 53, and four convex portions 54 are formed concentrically at intervals of 45 ° with the convex portion 56 as the center. A hole 57 is formed at the center position of the convex portion 56.

  When the contact surface 53 is pressed to the massage position when the massage device 10A is used, the convex portions 54 and 56 are pressed against the massage position, thereby preventing slippage between the massage position and the contact surface 53. To do. Thereby, the twist effect mentioned later can be made to act effectively on a massage position.

The inner cylinder part 58 is formed inside the outer cylinder part 51 and is formed to extend downward (toward the X1 direction) from the back surface of the contact surface 53. The nozzle part 34 formed in the inner 3 is inserted into the inner cylinder part 58 . At this time, the nozzle part 34 is configured to be movable to the inner cylinder part 58.

  When the massage head 5 is attached to the inner 3 and outer 4, as shown in FIG. 5, the spring 7 is attached to the outer peripheral position of the inner cylinder portion 58, and the sponge 8 is attached to the inside of the inner cylinder portion 58. Is done. The spring 7 constitutes the rotation urging mechanism 6 and has a function of urging the massage head 5 in the X2 direction with respect to the inner 3. Further, the sponge 8 has a function of closing the hole 57.

  Next, the rotation urging mechanism 6 will be described. The rotation urging mechanism 6 has a function of rotating the massage head 5 by pressing the massage head 5 to the massage position. The rotation urging mechanism 6 includes an engagement pin 45, a cam groove 55A, a spring 7, and the like.

  As described above, the engaging pin 45 is disposed on the outer main body 41 of the outer 4, and a tip portion thereof protrudes inward from the inner wall of the outer main body 41. The cam groove 55 </ b> A is formed on the surface of the cylindrical portion 51. The shape of the cam groove 55A is a shape (spiral shape) extending from the upper right direction to the lower left direction as shown in FIG. As shown in FIG. 3, the engaging pin 45 is configured to engage with the cam groove 55A. Therefore, the engaging pin 45 and the cam groove 55A cooperate to constitute a cylindrical cam.

  In the present embodiment, the spring 7 uses a coil spring, and is disposed between the back surface of the contact surface 53 and the inner 3 (specifically, the stepped portion 37) as shown in FIG. Due to the elastic force of the spring 7, the massage head 5 is biased with respect to the inner 3 in the direction of the arrow X <b> 2.

  Next, the operation of the massage apparatus 10A configured as described above will be described with reference to FIGS. 3A, 4A, and 5A show a state before the massage device 10A is pressed to the massage position of the user (hereinafter referred to as a pre-press state), and FIG. (B), FIG. 4 (B), and FIG. 5 (B) have shown the state (henceforth a press state) which pressed 10 A of massage apparatuses to the user's massage position.

  In the state before pressing, the spring 7 is in an extended state, and the massage head 5 is in a state of moving in the arrow X2 direction with respect to the inner 3 and outer 4. In the state before pressing, the head portion 52 of the massage head 5 is in a state of protruding from the head receiving portion 43 of the outer 4.

  Even in the pre-press state, the spring 7 biases the massage head 5 in the direction of the arrow X2, but a locking mechanism (not shown) is provided between the outer 4 and the massage head 5. FIG. The movement of the massage head 5 in the X2 direction is further restricted from the positions shown in FIGS. 4A, 4A, and 5A.

  When the user grips the grip portion 1 of the massage device 10A and presses (presses) the massage head 5 to the massage position from this pre-pressing state, the massage head 5 resists the elastic force of the spring 7 and moves to the arrow X1. Start moving in the direction.

  At this time, the engagement pin 45 constituting the rotation urging mechanism 6 is engaged with the cam groove 55A. For this reason, with the movement of the massage head 5 in the X1 direction, the engagement pin 45 relatively advances in the cam groove 55A. Since the cam groove 55A has a shape (spiral shape) extending from the upper right to the lower left as described above, the engagement pin 45 moves relatively in the cam groove 55A, so that the massage is performed. The head 5 is rotated. Thus, in the massage apparatus 10A according to the present embodiment, when the massage head 5 moves in the X1 direction, the massage head 5 rotates in the direction of the arrow A1 in the drawing along with this movement.

  When the massage device 10A is used, the contact surface 53 of the massage head 5 is in a state of touching the user's massage position (user's skin). Therefore, as the massage head 5 moves in the X1 direction and the contact surface 53 rotates as in the present embodiment, the massage position is pressed and twisted by the massage head 5.

  Thus, according to the massage apparatus 10A according to the present embodiment, two massage processes of pressing the massage position and torsion can be performed at the same time, so that it is more effective than a conventional massage that simply presses. It becomes possible to perform a simple massage.

  When the massage device 10A is moved away from the massage position from the pressed state, the spring 7 is elastically restored, the massage head 5 expands in the X2 direction and rotates backward (rotates in the A2 direction) to return to the pre-press state again.

  By the way, the amount of twist at the massage position by the massage device 10A is determined by the amount of rotation of the massage head 5 (contact surface 53). In the present embodiment, the rotation angle of the massage head 5 (contact surface 53) that rotates with the movement in the X1 direction is set to 5 ° or more and 180 ° or less. This is because when the rotation angle of the contact surface 53 is less than 5 °, the amount of twist is small, and the massage effect due to twist cannot be sufficiently exhibited. Further, if the rotation angle of the contact surface 53 exceeds 180 °, the massage position is excessively twisted, and an effective massage effect cannot be obtained.

  Moreover, in order to improve the usability of the massage device 10A, it is necessary for the massage head 5 to rotate smoothly when the user presses the massage device 10A to the massage position. Moreover, in order for the massage head 5 to rotate smoothly, it is necessary to optimize the spring constant of the spring 7. In this embodiment, the spring constant of the spring 7 is set to 0.1 N / mm or more and 0.5 N / mm or less.

  This is because when the spring constant of the spring 7 is less than 0.1 N / mm, the massage head 5 moves and rotates with a light pressing force. This is because slipping occurs between the position (the user's skin) and effective torsion is not performed.

  Further, when the spring constant of the spring 7 is set to a value exceeding 0.5 N / mm, the massage head 5 does not easily move in the X1 direction even when the massage device 10A is pressed to the massage position. The amount of rotation becomes smaller. For this reason, it is because a massage position cannot fully be twisted and the massage effect by twist will reduce.

  In addition, in order to realize massage with good torsion, it is necessary to optimize the relationship between the amount of movement of the massage head 5 in the X1 direction and the rotation angle of the contact surface 53 during use. That is, if the rotation angle of the contact surface 53 is small even though the movement amount of the massage head 5 in the X1 direction is long, the massage effect by torsion is reduced. On the contrary, if the rotation angle of the contact surface 53 is large with respect to the movement amount of the massage head 5 in the X1 direction, slipping may occur between the skin and the contact surface 53, or the skin at the massage position may be excessively twisted. As a result, the usability deteriorates.

Therefore, in this embodiment, when the massage head 5 moves 20 mm in the X1 direction, the massage head 5 (contact surface 53) is set to rotate by 45 ° . With this configuration, it is possible to optimize the balance between the acupressure effect associated with the movement of the massage head 5 in the X1 direction and the massage effect due to the torsion associated with the rotation of the step portion 23.

  In addition, the rotation angle with respect to the movement amount of the massage head 5 in the X1 direction is not limited to the above-described embodiment, and can be appropriately adjusted. For example, in this embodiment, the rotation angle can be set in a rotation range of 5 ° to 180 ° by moving the massage head 5 by 20 mm.

  FIG. 6 shows a massage device 10B which is a modification of the massage device 10A shown in FIGS. In FIG. 6, configurations corresponding to the configurations of the massage device 10 </ b> A illustrated in FIGS. 1 to 5 are denoted by the same reference numerals, and description thereof is omitted.

  The massage device 10A described above is configured such that when the massage head 5 is pressed to the massage position, the massage head 5 rotates only in the direction indicated by the arrow A1 in the drawing. That is, 10 A of massage apparatuses were set as the structure which twists the skin which the contact surface 53 contacts in a massage position only to one direction.

  On the other hand, the massage apparatus 10B according to the modification is configured such that the massage head 5 rotates in both directions A1 and A2 when the massage head 5 is pressed (pressed) against the massage position. To do.

In the massage device 10A described above, a cam groove 55A that extends from the upper right to the lower left is formed in the outer cylindrical portion 51 of the massage head 5. On the other hand, this modification is characterized in that a lateral V-shaped cam groove 55B is formed. The cam groove 55B has a cam portion 55B-1 extending obliquely downward with the position P as the center, and a cam portion 55B-2 extending obliquely upward with the position P as the center.

  In the pre-pressing state, the engagement pin 45 is engaged with the cam portion 55B-1 located below the position P (X1 side). Therefore, when the massage device 10B is pressed to the massage position from the pre-press state, the engagement pin 45 relatively moves in the cam portion 55B-1, and thus the massage head 5 rotates in the A1 direction. When the engagement pin 45 passes the position P and reaches the cam portion 55B-2, the rotation direction of the massage head 5 is reversed and rotates in the A1 direction.

  As described above, in the massage device 10B according to this modification, while the massage head 5 moves in the X1 direction until the massage head 5 is in a pressed state, the massage head 5 is rotated in two directions: rotation in the A1 direction and rotation in the A2 direction. Can be rotated. Thereby, compared with the massage apparatus 10A in which the massage head 5 (contact surface 53) rotates only in a single direction, the massage effect by twisting can be further enhanced.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific embodiments described above, and various modifications are possible within the scope of the gist of the present invention described in the claims. It can be modified and changed.

  For example, in the above-described embodiment, an example in which the engagement pin 45 is provided in the outer 4 and the cam grooves 55A and 55B are formed in the massage head 5 is shown. However, a cam groove is formed on the inner wall of the outer 4 (outer body 41), and an engagement pin that engages with the cam groove is provided in the massage head 5, and the same as in the above-described embodiment. An effect can be obtained.

  Moreover, in above-described embodiment, the structural example which provided only one massage head 5 with respect to the outer 4 was shown. However, the number of massage heads 5 disposed on the outer 4 is not limited to one, and a plurality of massage heads can be disposed.

  At this time, the direction of the massage head that rotates by being pressed against the skin does not have to be the same in all the massage heads, and can be set so that the rotation direction is different in each massage head. Furthermore, the spring constant of the spring can be changed for each massage head, or the amount of rotation when moving in the X1 direction can be changed. Thereby, it is possible to perform a plurality of different types of massages with one massage device, and to further improve the massage effect.
