Description

  The present invention relates to a power-driven massage device, and more particularly to a massage device that massages the scalp and the like.

Conventionally, as this type of massage device, there is a drive unit and a treatment unit operated by the drive unit, and the positional relationship of the peripheral edge of the substrate of the treatment unit with respect to the drive unit is fixed to the drive unit And a reciprocating drive means for bending the substrate in a direction intersecting the surface of the substrate, and the treatment portion is made of a flexible material, and the substrate. What is comprised with the some protrusion provided by protruding in the board | substrate is known. Then, the massage device bends the plurality of protrusions provided on the substrate repeatedly as the substrate is bent by bending the substrate of the treatment portion by the reciprocating drive means during the massage. The scalp can be massaged in a complex manner so that the scalp can be rubbed, rubbed and struck by the protrusions that open and close each other. Then, when the treatment unit has a central axis as the amplitude direction in the maximum amplitude portion of the substrate, the plurality of protrusions face the central axis and are connected to the substrate from a proximal end side to a distal end side. A triangular pyramid-shaped first protrusion provided with an opposing surface formed in a substantially triangular shape so as to become gradually thinner. (For example, patent document 1). As shown in FIGS. 6 and 7, this is because the substrate 103 in the treatment unit 102 driven by the driving unit 101 is deformed between a curved convex state where the substrate 103 is bent downward and a curved concave state where the substrate 103 is bent upward. When repeating, a plurality of types of protrusions 104, 105, 106 move with the bending of the substrate 103, and the scalp S can be massaged by the protrusions 104, 105, 106. Of the plurality of protrusions, the first protrusion 106 is located between the narrow distal end side and the wide proximal end side when the scalp or the like is massaged. By moving, it is possible to perform massage and the like performed with a fingertip.

  However, in the prior art, since the contact pressure of the first protrusion with respect to the scalp is relatively large, there is a possibility that it cannot be softly contacted. That is, when the scalp or the like is massaged using such a conventional massage device, the user may feel a slight pain on the scalp or the like. This is due to the fact that the first protrusion has a triangular pyramid shape, so that its tip is hardly elastically deformed.

  An object of the present invention is to solve the above-mentioned problems and to provide a massage device capable of performing a gentle and effective massage closer to a human finger when performing massage such as a scalp.

  The invention of claim 1 has a drive unit and a treatment unit operated by the drive unit, and the treatment unit is provided on a substrate made of a flexible material and protruding from the surface of the substrate. The driving unit is provided with a frame that detachably holds the peripheral edge of the substrate in a state in which the positional relationship with the driving unit is fixed, and in a direction intersecting the surface of the substrate. In the massage apparatus provided with the reciprocating drive means for bending the substrate, the plurality of protrusions have a plurality of first protrusions provided with treatment surfaces facing inward, and the amplitude direction in the maximum amplitude portion of the substrate is determined. When the central axis is used, the treatment surface of the first protrusion is formed in a convex curved shape so that the distal end side is separated from the central axis with respect to the base end connected to the substrate, and the outer side of the first protrusion is Form a facing depression And in a massaging apparatus being characterized in that the distal end side is easily elastically deformable formed in the first protrusion.

  According to a second aspect of the present invention, a second protrusion configured to be less deformable than the first protrusion is provided between the first protrusions, and the height of the first protrusion is increased in the central axis direction. The massage apparatus according to claim 1, wherein the massage apparatus is formed higher than a height of the second protrusion.

  According to the first aspect of the present invention, when the scalp or the like is massaged, the depressed portion is formed in the first protrusion that comes into contact with the scalp or the like, so that the tip side of the first protrusion is easily elastically deformed. Since this is possible, when the treatment surface is pressed against the scalp or the like as the substrate is bent, the distal end side of the first protrusion is elastically deformed appropriately. As a result, the contact pressure of the first protrusion on the scalp can be relieved, so that a gentle and effective massage can be performed on the scalp and the like as with a fingertip.

  Further, according to the invention of claim 2, even if the treatment portion is pressed against the scalp or the like until the distal end side of the second protrusion comes into contact with the scalp, the massage device body and the scalp are deformed by the second protrusion that is not easily deformed. Is kept within an appropriate range. Accordingly, the first protrusion can be prevented from being pressed too much against the scalp or the like.

  Preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments described below do not limit the contents of the present invention described in the claims. In addition, all of the configurations described below are not necessarily essential requirements of the present invention.

  1 to 5 show a first embodiment. In this example, the upper and lower sides are defined based on the posture shown in FIG. Reference numeral 1 denotes a massage device according to the present invention. The massage device 1 includes a massage device body 2 as a drive unit and a treatment unit 3 that is detachably held on the lower side of the massage device body 2. And this treatment part 3 is comprised by the board | substrate 4 and the 1st processus | protrusion 5, the 2nd processus | protrusion 6, and the 3rd processus | protrusion 7 which were integrally provided by projecting to the downward side which is the direction which cross | intersects the lower surface of this board | substrate 4. Has been. The substrate 4 is elliptical in plan view and is formed of an elastomer having flexibility and elasticity. And the edge 4A of the said board | substrate 4 is being fixed to the lower edge side of the said massage apparatus main body 2. As shown in FIG. The term “fixed” as used herein includes a state in which connection is allowed with some movement. In this embodiment, the edge 4A of the substrate 4 extends along the lower surface of the massage device body 2. By being fitted to a fixing frame 8 made of the formed groove, both are detachably connected over the entire circumference.

  The massage device body 2 has a case body 2A having an opening on the bottom side and a size that can be grasped with one hand, and a bottom surface portion 2B that closes the opened bottom side of the case body 2A. The bottom surface portion 2B includes a bottom plate 9 and a cover body 11. The bottom plate 9 is formed in an elliptical shape in plan view, and its outer periphery is fixed to the bottom edge of the case main body 2A. The bottom plate 9 has a circular shape penetrating in the vertical direction in the center portion of the bottom plate 9. A window hole 10 is formed, and the cover body 11 that covers the window hole 10 and can be expanded and contracted is provided. The cover 11 is provided so as to seal the window hole 10 in a watertight manner by a bellows-like film made of a flexible material such as rubber, synthetic rubber, or elastomer. And inside the said massage apparatus main body 2, the reciprocating drive means 12 which reciprocates the center part of the said board | substrate 4 to an up-down direction is provided. The reciprocating drive means 12 includes a motor 13 as a drive source provided on the bottom plate 9, a crank mechanism 15 connected to a motor shaft 13 A of the motor 13 via a reduction gear mechanism 14, and the crank mechanism 15 A connecting rod 16 having one side connected to the eccentric shaft 15A is provided. Note that a connection relay member 17 is integrally attached to substantially the center of the cover body 11. The connection relay member 17 sandwiches and fixes the cover body 11 between the upper surface side and the other side of the connecting rod 16, and is provided with a hook 17A on the lower surface side. A hook receiving portion 4B provided on the central upper surface is detachably connected. Therefore, the connection relay member 17 is reciprocated in the vertical direction by converting the rotational motion of the motor 13 into the reciprocating motion by the crank mechanism 15 and the connecting rod 16. Thereby, the position where the hook receiving portion 4B is provided becomes the maximum amplitude portion in the substrate 4, and the amplitude thereof is twice the eccentric distance F from the central axis of the crank mechanism 15 to the eccentric shaft 15A (2F). ) Further, a virtual center axis X is formed in the vertical direction through the hook receiving portion 4B and the connection relay member 17. In addition, a battery 18 for supplying electric power to the motor 13 is provided inside the massage apparatus body 2, and the motor 13 is operated on the upper surface side surface of the massage apparatus body 2. The switch 19 is provided.

  The treatment unit 3 will be described in detail. The first protrusion 5 and the second protrusion 6 are formed on an elliptical outer outer ring O arranged along the edge 4A of the substrate 4 with the center axis X passing through the substantial center of the substrate 4 up and down. It is provided along. Further, the third protrusion 7 is provided along a circular virtual inner ring I disposed inside the virtual outer ring O.

  The first protrusions 5 provided at intervals along the virtual outer ring O are provided at a plurality of intervals so as to face each other about the central axis X. In this example, a total of eight first protrusions 5 are provided by providing a group of four elliptical arcs arranged in two locations so as to be axially symmetric. The treatment surface 20 of the first protrusion 5 is formed with a rounded tip 21 side. On the other hand, the treatment surface 20 of the first protrusion 5 has a substantially constant width W from the intermediate portion to the base end 22 or is slightly narrower on the base end 22 side. The treatment surface 20 recedes in a curved convex shape from the proximal end 22 side to the distal end 21 side so that the distal end 21 side is longer than the proximal end 22 side by a distance L from the central axis X. . That is, as shown in FIG. 4, the treatment surface 20 has a slope that decreases from the proximal end 22 toward the distal end 21.

  A depressed portion 5 </ b> A is formed on the outer side of the first protrusion 5 on the tip 21 side, that is, on the opposite side of the treatment surface 20. In addition, a pair of support walls 5B are formed outward in the middle portion of the first protrusion 5, that is, on both side edges between the distal end 21 and the proximal end 22. Further, the proximal end 22 side of the first protrusion 5 is a cylindrical portion 5C, and the distal end 21 side of the cylindrical portion 5C is closed by an end plate portion 5D. Accordingly, the first protrusion 5 is provided by extending the distal end 21 side of the treatment surface 20 on the distal end side of the cylindrical portion 5C whose distal end is closed by the end plate portion 5D, and an intermediate portion of the treatment surface 20 It has a structure in which a pair of support walls 5B are provided on both side edges. And since the said support walls 5B are not connected, these support walls 5B do not support each other. Accordingly, when a load is applied to the treatment surface 20, the distal end 21 side of the treatment surface 20 bends, and the support walls 5 </ b> B provided on both side edges of the treatment surface 20 also bend. Note that the distal end 21 of the treatment surface 20 where the support wall 5B is not provided is easily bent by a light force, and the intermediate portion of the treatment surface 20 provided with the support wall 5B is slightly difficult to bend. The proximal end 22 side of the treatment surface 20 which is the shape portion 5C hardly bends. That is, the treatment surface 20 is more easily bent on the distal end 21 side than on the proximal end 22 side. The thickness of the treatment surface 20 itself, the size and thickness of the support wall 5B, and the like are factors that determine the ease of bending of the treatment surface 20.

  The second protrusion 6 is formed integrally with the substrate 4 between the ends of the first protrusion 5 group arranged in an elliptical arc shape. In the embodiment, a pair of the second protrusions 6 are provided on the virtual outer ring O and opposite to both ends in the long axis direction of the substrate 4. The height H1 (from the base end 22 to the tip 21) of the first protrusion 5 in the central axis X direction is higher than the height H2 (from the base end 22 ′ to the tip 21 ′) of the second protrusion 6. Is also formed high. The second protrusion 6 has a cylindrical shape in which the side facing the central axis X is cut out into a convex curved surface, and the facing surface 20 ′ facing the central axis X has the same shape as the treatment surface 20. It has become. The second protrusion 6 is integrally formed in a convex shape with substantially the same thickness as the plate-like substrate 4, and for this reason, a hollow portion 24 is formed inside the second protrusion 6. Is formed. And unlike the said 1st protrusion 5, since the said 2nd protrusion 6 is not formed in the recessed part, since the said opposing surface 20 'is supported by another part, even if a load is added, it hardly deform | transforms. Further, since the second protrusion 6 itself is formed at both ends of the substrate 4 in the long axis direction, it does not move greatly even if the substrate 4 is bent.

  Further, the plurality of third projections 7 provided at intervals along the virtual inner ring I have a cylindrical shape with a slightly narrower tip side and a rounded tip side, and the height in the direction of the central axis X H3 is formed to be lower than the height H1 of the first protrusion 5 and the height H2 of the second protrusion 6.

  Next, the effect | action is demonstrated about the said structure. When massaging the scalp S, the user first holds the massage device body 2 and operates the switch 19. When the switch 19 is operated, electric power is supplied from the battery 18, whereby the motor 13 is operated and the motor shaft 13A is rotated. Along with this rotation, the crank mechanism 15 connected to the motor shaft 13A via the reduction gear mechanism 14 rotates, and this crank mechanism 15 and the connecting rod 16 connected to the eccentric shaft 15A of the crank mechanism 15 are rotated. Rotational motion of the motor shaft 13A is converted into reciprocating motion, and the connection relay member 17 connected to the connecting rod 16 reciprocates up and down. Then, the substrate 4 is bent in the same manner as in the prior art so that the hook receiving portion 4B connected to the connection relay member 17, that is, the center of the substrate 4 becomes the maximum amplitude portion. The deformation at the maximum amplitude position is twice as large as the eccentric distance F from the central axis of the crank mechanism 15 to the eccentric shaft 15A (2F). Become. Then, by repeating the deformation between the curved convex state where the substrate 4 is bent downward and the curved concave state where the substrate 4 is bent upward, the projections 5 provided integrally with the substrate 4 are provided. 6 and 7 also open and close each other by repeatedly falling and getting up.

  Then, the user presses the treatment portion 3 on which the projections 5, 6, and 7 operate in this manner against the scalp S. At this time, the height H1 of the first protrusion 5 in the no-load state is higher than the height H2 of the second protrusion 6 so that the tip 21 'of the second protrusion 6 comes into contact with the scalp S. Further, when the treatment portion 3 is pressed, the tip 21 side of the first protrusion 5 is elastically deformed. As described above, since the recessed portion 5A is formed outside the treatment surface 20 of the first protrusion 5, the support walls 5B supporting the treatment surface 20 are not connected to each other. This is because the distal end 21 side of the treatment surface 20 is configured to be elastically deformable with a relatively light force. Then, the substrate 4 is repeatedly bent between the curved convex state and the curved concave state, so that the first protrusion 5 is repeatedly brought up and down in a state where the first protrusion 5 is in contact with the scalp S and is bent. The scalp S is massaged so as to be grasped by the one protrusion 5. At this time, the first protrusion 5 is receding in a curved convex shape from the base end 22 side to the tip end 21 side so that the tip end 21 side is separated from the central axis X rather than the base end 22 side. When the first protrusion 5 is repeatedly tilted while being elastically deformed, the treatment surface 20 in contact with the scalp S can be squeezed so that the scalp S slides from the intermediate portion to the tip 21 side. The treatment surface 20 of the first protrusion 5 is formed such that the proximal end 22 side is less likely to be elastically deformed than the distal end 21 side, so that the treatment is performed when the first protrusion 5 is raised. While the surface 20 has a portion slightly closer to the base end 22 than the distal end 21 slightly hits the scalp S, the treatment surface 20 has a portion closer to the distal end 21 in a state where the first protrusion is tilted. Softly hits the scalp S. As described above, the tip 21 of the treatment surface 20 is elastically deformed, so that the contact pressure of the treatment surface 20 to the scalp S can be reduced, and gentle and effective massage as performed with a fingertip can be performed. .

  On the other hand, since the second protrusions 6 are formed at both ends of the long axis direction of the substrate 4 as described above, even if the substrate 4 is bent, the second protrusions 6 are almost moved with a slight swing. In addition, it hardly elastically deforms itself. However, although the second protrusion 6 itself that hardly moves and hardly elastically deforms hardly massages, the distance between the massage device body 2 and the scalp S is maintained within an appropriate range by the second protrusion 6. It is prevented that the treatment part 3 is pressed against the scalp S more strongly than necessary. If the second protrusion 6 is not provided, the massager body is pressed against the scalp S more strongly than necessary, and the massaging device main body is caused by a reaction accompanying the rising and falling of the first protrusion 5. 2. As a result, the user's hand that vibrates greatly vibrates in the direction of the central axis X, or conversely, the head against which the treatment unit 3 is pressed is greatly shaken, and the first projection 5 There is a possibility that massage is not performed well. However, since the second protrusion 6 is provided, an interval between the massage device body 2 and the scalp S is maintained within an appropriate range, so that the treatment unit 3 is stronger than necessary with respect to the scalp S. Since the hand of the user holding the massage device main body 2 and the head against which the treatment unit 3 is pressed are not greatly shaken without being pressed, the massage by the first protrusion 5 is favorably performed. Become.

  The third protrusion 7 repeats approaching (or abutting) and separation with respect to the scalp S due to the bending of the substrate 4. That is, the third protrusion 7 is only close to or in contact with the shape of the user's head. If the third protrusion 7 is not provided, the center of the substrate 4 may directly collide with the scalp S depending on the shape of the user's head. However, even in such a case, since the third protrusion 7 is provided, when the third protrusion 7 collides with the scalp S, it can be easily bent and the impact can be reduced. The hand of the user having the massage device body 2 and the head against which the treatment unit 3 is pressed are not greatly shaken, and the massage by the first protrusion 5 is performed well.

  As mentioned above, in the said Example, the treatment part 3 which consists of the board | substrate 4 which has flexibility, and the some protrusion 5-7 provided in the board | substrate 4 so that the surface of this board | substrate 4 may be crossed is driven. The reciprocating drive means 12 in the massage apparatus body 2 as a unit and the reciprocating drive means 12 in the massage apparatus body 2 are detachably held in a state where the positional relationship with respect to the massage apparatus body 2 is fixed. The massaging device 1 for massaging the scalp S and the like by the projections 5 to 7 by repeatedly bending the substrate 4 in a direction intersecting the surface thereof, with the amplitude direction at the maximum amplitude portion of the substrate 4 being the center When the axis X is taken, the plurality of first protrusions 5 are provided with an inward treatment surface 20 formed in a convex curved shape so that the distal end 21 side is separated from the central axis X with respect to the base end 22, and By forming the recessed portion 5A facing outward on the first protrusion 5, the tip 21 side of the first protrusion 5 can be easily elastically deformed, so that the contact pressure on the treatment surface 20 is reduced. It is possible to perform a gentle and effective massage on the scalp S and the like as with a fingertip.

  In addition, a second protrusion 6 is provided between the first protrusions 5 and is configured to be less deformable than the first protrusion, and the height H1 of the first protrusion 5 is set to the first axis 5 in the direction of the central axis X. By forming the second protrusion 7 higher than the height H2, even if the treatment part 3 is pressed against the scalp S or the like until the tip 21 'of the second protrusion 6 contacts the scalp S, the second protrusion is difficult to deform. Since the gap between the massage device main body 2 and the scalp S is maintained within an appropriate range by the protrusions 6, the first protrusion 5 can be prevented from being pressed too much against the scalp S or the like.

  In addition, a pair of support walls 5B are formed outward on both side edges in the middle portion of the treatment surface 20, and the treatment surface 20 is reinforced by the support walls 5B, so that the distal end 21 side of the treatment surface 20 is It is possible to avoid a case where a sufficient massage effect cannot be obtained due to excessive bending.

  Moreover, the treatment surface 20 is receding in a curved convex shape from the proximal end 22 side to the distal end 21 side so that the distal end 21 side is separated from the central axis X rather than the proximal end 22 side. When the first protrusion 5 repeats ups and downs while being elastically deformed, the facing surface 20 that comes into contact with the scalp S can be squeezed so that the scalp S slides from the middle part to the tip 21 side.

  Further, since the first protrusion 5 is provided in an annular shape with a plurality of intervals around the central axis X, the first protrusion 5 can be disposed so as to surround the scalp S.

  In addition, the massage apparatus of this invention is not limited to the above Example, A various deformation | transformation implementation is possible within the range of the summary of invention. For example, in the above embodiment, the depressed portion is provided on the outer side of the tip end side of the first protrusion, but the depressed portion may be provided on the outer side of the entire first protrusion. Moreover, in the said Example, although a 2nd protrusion has an opposing surface of the shape similar to the treatment surface provided in the 1st protrusion, such an opposing surface does not need to be provided.

  As described above, the massage device according to the present invention can be applied to a device used for a part other than the scalp in addition to a device used for massaging the scalp.
