  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. Reference numeral 1 denotes a brush device that also serves as a massage device, and a brush portion 2 is provided on the lower side of the brush device 1. The brush portion 2 includes a substrate 3 and a plurality of protrusions 4 that are integrally provided so as to protrude toward the side surface 3A of the substrate 3. The substrate 3 has a disk shape with the axis A as the center, and is formed of a soft synthetic resin having flexibility. And the edge 3B of this board | substrate 3 is being fixed to the whole inner periphery of the frame 5 of the said brush apparatus 1. FIG. The plurality of protrusions 4 are formed in a single body with the substrate 3 so as to be substantially axially symmetric with respect to the axis A as well as having a base shape with the base end 4A slightly thicker. Further, each of the protrusions 4 is formed so as to protrude so that the axis D intersects the one side surface 3A of the substrate 3 substantially perpendicularly. Note that the base end 4 </ b> A of the protrusion 4 does not depend on the bending of the substrate 3, and remains substantially perpendicular to the one side surface 3 </ b> A of the substrate 3. The frame 5 is made of an inflexible hard synthetic resin, and is formed in an annular shape around the axis A with the entire circumference of the edge 3B of the substrate 3 being fixed. In the figure, B is the width direction of the substrate 3, the substrate 3 is widely formed in the width direction B intersecting perpendicularly to the axis A, and the plurality of protrusions 4 are spaced from each other by a distance C. Is placed.

  In addition, a cover 6 constituting a driving unit is provided integrally with the frame body 5 so as to cover the upper side of the substrate 3. A reciprocating drive means 7 for reciprocating the center of the substrate 3 along the axis A in the vertical direction is provided in the cover 6. The reciprocating drive means 7 is attached to a motor 8 as a drive unit provided integrally with the frame 5 via an attachment receiving member 6 A such as a bracket in the cover 6, and a motor shaft 8 A of the motor 8. The crank mechanism 9 and the eccentric shaft 9A of the crank mechanism 9 are connected to one side 10A so as to be rotatable, and the other side 10B is swung with respect to the approximate center of the other side surface 3C of the substrate 3. The connecting rod 10 is connected freely. The motor 8 has a speed reduction mechanism (not shown), and rotates the motor shaft 8A by decelerating the rotation at a predetermined speed reduction ratio. The eccentric distance between the motor shaft 8A of the motor 8 and the eccentric shaft 9A of the crank mechanism 9 is F. Therefore, when the motor shaft 8A of the motor 8 rotates, the rotation of the motor shaft 8A is converted into a reciprocating motion by the crank mechanism 9 and the connecting rod 10, and the central portion of the substrate 3 is moved to the axis A by the connecting rod 10. Reciprocate up and down. As described above, since the edge 3B of the substrate 3 is fixed to the frame body 5, even if the center of the substrate 3 reciprocates up and down along the axis A, the edge 3B Do not move. Accordingly, the substrate 3 is deformed between the curved concave state bent upward and the curved convex state bent downward as shown in FIGS. 4 and 5 by the rotation of the motor 8. Further, a battery case 11 for accommodating a battery (not shown) is provided in the cover 6, and a switch 12 for operating the motor 8 is provided on the surface of the cover 6.

  Next, the effect | action is demonstrated about the said structure. When washing hair, the user first holds the brush device 1 and presses the tip 4B of the protrusion 4 of the brush portion 2 against the scalp G. At this time, the tip 4B of the protrusion 4 is pressed against the scalp G with a light force. Next, when the switch 12 is closed, power is supplied from a battery (not shown), so that the motor 8 operates and the motor shaft 8A rotates. Along with this rotation, the crank mechanism 9 attached to the motor shaft 8A rotates, and the crank mechanism 9 and the connecting rod 10 connected to the eccentric shaft 9A of the crank mechanism 9 rotate the motor shaft 8A. Is converted into a reciprocating motion, and the substrate 3 connected to the connecting rod 10 reciprocates at the center along the axis A. The deformation with an amplitude of 2F is repeated between the bent curved convex states.

  As shown in FIG. 4, when the eccentric shaft 9A of the crank mechanism 9 is above the motor shaft 8A, the substrate 3 is pulled upward by the connecting rod 10 so that the substrate 3 is located with its center at the top. It will be in the bent curved concave state. Of the protrusions 4 formed integrally with the substrate 3 so as to be orthogonal to the one side surface 3A of the substrate 3, at least the base end 4A is accompanied by the bending of the one side surface 3A of the substrate 3. Thus, by moving integrally while maintaining an orthogonal state with the one side surface 3A, the tips 4B of the plurality of projections 4 are closed, that is, the axes D at least at the base ends 4A of the plurality of projections 4 are inward. It will move in the direction. In fact, as described above, the tip 4B of the projection 4 is always in contact with the scalp G because the tip 4B of the projection 4 is pressed against the scalp G with a light force. As a result, among the protrusions 4 formed of a soft synthetic resin having flexibility, at least the base end 4A formed thick at the protrusions 4 formed on the outer peripheral side of the substrate 3 is slightly bent. However, it is substantially not deformed and maintains a state substantially orthogonal to one side surface 3A of the substrate 3, while the thin tip 4B side comes into contact with the scalp G in a largely bent state. . Then, the motor 8 rotates in this way and the substrate 3 of the brush portion 2 bends upward, so that the protrusion 4 moves inward while in contact with the scalp G. At the same time that the scalp G is massaged by the tip 4B of the protrusion 4, not only the scalp G but also the hair H is washed by a hair wash or the like. As described above, the pressing force of the brush portion 2 to the scalp G and the tip 4B of the protrusion 4 bend in accordance with the movement of the protrusion 4, so that the scalp G is softly massaged with a touch. And will be washed.

  Thereafter, when the eccentric shaft 9A of the crank mechanism 9 is rotated downward from the top dead center, the substrate 3 is pushed and deformed gradually by the connecting rod 10, and as shown in FIG. It becomes the curved convex state bent downward. In this process, at least the base end 4A of the protrusions 4 moves integrally with the one side surface 3A substantially in an orthogonal state with the bending of the one side surface 3A of the substrate 3, thereby The protrusions 4B of the plurality of protrusions 4 open, that is, move so that the axes D of at least the base ends 4A of the plurality of protrusions 4 face outward. In fact, as described above, the tip 4B of the projection 4 is always in contact with the scalp G because the tip 4B of the projection 4 is pressed against the scalp G with a light force. As a result, among the protrusions 4 formed of the soft synthetic resin having flexibility, at least the base end 4A formed thick at the protrusion 4 formed at the central portion of the substrate 3 is slightly bent. However, it is substantially not deformed and maintains a state substantially orthogonal to one side surface 3A of the substrate 3, while the thin tip 4B side comes into contact with the scalp G in a largely bent state. . Then, the motor 8 rotates in this way and the substrate 3 of the brush portion 2 bends downward, so that the protrusion 4 moves outward in a state of being in contact with the scalp G. The scalp G is massaged so as to be spread by the tip 4B of the protrusion 4, and at the same time, not only the scalp G but also the hair H is washed by a hair washing agent or the like. As described above, the pressing force of the brush portion 2 to the scalp G and the tip 4B of the protrusion 4 bend in accordance with the movement of the protrusion 4, so that the scalp G is softly massaged with a touch. And will be washed.

  In this way, the rotational force of the motor 8 is converted into a reciprocating motion by the crank mechanism 9 and the connecting rod 10, and the substrate 3 of the brush portion 2 is repeatedly bent in a state where the protrusion 4 is kept in contact with the scalp G. Then, by repeatedly closing and opening the plurality of protrusions 4 integrally provided on the substrate 3, the scalp G is stimulated to be gripped or spread by the plurality of protrusions 4 and massaged. The hair H as well as the scalp G is washed by the friction of the tip 4B of the projection 4 with the scalp G due to the movement of the plurality of projections 4 and the action of the hair washing agent.

  As described above, in the embodiment, the plurality of protrusions 4 are substantially symmetrical about the axis A of the substrate 3 on one side surface 3A of the flexible substrate 3 of the brush portion 2, and the The projection 4 is formed integrally with the substrate 3 so that the axis D of the projection 3 is orthogonal to the side surface 3A of the substrate 3, the edge 3B of the substrate 3 is fixed to the frame body 5, and the motor 8 as a drive unit is provided. When operated, the substrate 3 connected to the reciprocating drive means 7 is moved along the axis A between the curved concave state bent upward and the curved convex state bent downward. By repeatedly deforming, the plurality of protrusions 4 provided on the substrate 3 are repeatedly opened and closed, and the operation of grabbing and spreading the scalp G is repeated, and the scalp G is massaged and the scalp G and the hair H are Cleaning can be performed.

  Moreover, in the said Example, since the edge 3B perimeter of the said board | substrate 3 is being fixed to the said frame 5, the curved deformation of the said board | substrate 3 can be performed uniformly, and the massage of the scalp G and scalp G are evenly distributed. And hair H can be washed well.

  Moreover, in the said Example, since the base end 4A of the said protrusion 4 is formed thicker than the front-end | tip 4B, it is not dependent on the bending of the said board | substrate 3, but the axis line of the protrusion 4 with respect to the one side 3A of the said board | substrate 3 By maintaining the state where D is orthogonal, the plurality of protrusions 4 can be repeatedly opened and closed even when the brush portion 2 is operated by pressing the tip 4B of the protrusion 4 against the scalp G. And scalp G and hair H can be cleaned.

  Further, since the tip 4B of the projection 4 is formed to be narrower than the base end 4A, the tip 4B of the projection 4 bends when pressed against the scalp G. And hair H can be washed.

  Furthermore, by constituting the reciprocating drive means 7 with a motor 8, a crank mechanism 9 and a connecting rod 10, complicated movements of the plurality of protrusions 4 provided on the brush portion 2 can be easily realized. .

  FIG. 6 shows a second embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. In the second embodiment, the reciprocating drive means 7 is connected to a plurality of locations on a single substrate 3 that is formed of a flexible soft synthetic resin and is provided with a plurality of protrusions 4 integrally. It can be bent by reciprocating repeatedly. In this way, by connecting the reciprocating drive means 7 to a plurality of locations on the single substrate 3, even when the area of the substrate 3 is large, the substrate 3 can be flexed well. The scalp G can be massaged and the scalp G and hair H can be cleaned well by the large number of protrusions 4.

  7 to 8 show a third embodiment. The same reference numerals are given to the same portions as those of the respective embodiments, and the detailed description thereof will be omitted. In Example 3, the example which uses 1A of massage apparatuses is shown, This massage apparatus 1A makes the same structure as the brush apparatus 1 of each said Example, Comprising: It has the said brush part 2 which is a treatment part.

  And when massaging the affected part K, such as an arm, a shoulder, and a waist, a user hold | grips the said massage apparatus 1A and presses the front-end | tip 4B of the processus | protrusion 4 of the said brush part 2 against the affected part K first. At this time, the tip 4B of the protrusion 4 is pressed against the affected part K with a light force. Next, when the switch 12 is closed, the rotating motion of the motor shaft 8A is converted into a reciprocating motion by the connecting rod 10 as described above, and the substrate 3 connected to the connecting rod 10 is centered on the axis. By reciprocating along A, the crank mechanism 9 is repeatedly deformed so that the amplitude becomes 2F between the curved concave state bent upward and the curved convex state bent downward, as shown in FIG. When the eccentric shaft 9A is located above the motor shaft 8A, the substrate 3 is pulled up by the connecting rod 10, so that the substrate 3 is bent upward with its center at the top, and thus the motor 8 is rotated and the substrate 3 of the brush part 2 bends upward, so that the protrusion 4 moves inward while in contact with the affected part K. At this time, the affected part is moved by the tip 4B of the protrusion 4 K is grabbed It is massage.

  Subsequently, when the eccentric shaft 9A of the crank mechanism 9 is rotated downward from the top dead center, the substrate 3 is pushed by the connecting rod 10 to be gradually deformed, and as shown in FIG. In this way, the motor 8 rotates and the substrate 3 of the brush portion 2 bends downward, so that the projection 4 is in contact with the affected area K. At this time, the affected part K is massaged so as to be spread by the tip 4B of the protrusion 4.

  In this manner, the tip 4B of the projection 4 bends in accordance with the pressing force of the brush portion 2 against the affected portion K and the movement of the projection 4, so that the affected portion K is massaged with a feeling that it is softly rubbed.

  In this embodiment, the frame 5 is provided so as to hold the entire periphery of the substrate 3, and at least the base 4A of the protrusion 4 has a substantially constant angle with respect to the substrate 3 regardless of the bending of the substrate 3. Further, at least the tip 4B of the protrusion 4 is made of a flexible material, and the reciprocating drive means 7 is provided with a motor 8 which is an electric motor provided in the drive section, and the motor 8 directly. Alternatively, since the crank mechanism 9 that is indirectly connected and the connecting rod 10 that connects the one side 10A to the crank mechanism 9 and the other side 10B to the substrate 3 are provided, the same as in the above embodiments. Has an effective action and effect.

  9 and 10 show a fourth embodiment. The same reference numerals are given to the same portions as those of the respective embodiments, and the detailed description thereof will be omitted. In Example 4, the brush device 1 or the massage device 1A includes projections 4 ′ and 4 ″ having different lengths and / or thicknesses in addition to the projections 4, and the substrate 3 is substantially oval in a plane. It is formed into a shape. Further, as shown in FIG. 9, the brush device 1 is integrally provided with a handle portion 13.

  The protrusion 4 ′ is shorter than the protrusion 4, and the base end 4 A of the protrusion 4 ′ is thicker than the base end 4 A of the protrusion 4. Therefore, the protrusion 4 ′ is less flexible (easily bent) than the protrusion 4, and maintains a state almost orthogonal to the one side surface 3 </ b> A of the substrate 3 in use. The protrusion 4 ″ is shorter than the protrusions 4 and 4 ′, and the base end 4 A of the protrusion 4 ″ is formed to have substantially the same thickness as the base end 4 A of the protrusion 4. Accordingly, the protrusion 4 ′ is less flexible than the protrusion 4 by a short amount, and the bending of the tip 4 B is smaller than that of the protrusion 4 when receiving the same force during use. The protrusions 4 ′ and 4 ″ have the same configuration as the protrusion 4 except that the lengths and / or thicknesses are different. A plurality of the protrusions 4, 4 ′, 4 ″ are integrally projected on the side surface 3 A side of the substrate 3. A plurality of the protrusions 4 are provided on the peripheral side of the one side surface 3A of the substrate 3, and the protrusion 4 'is formed in a substantially ring shape around the axis A at the center surrounded by the protrusions 4. A plurality of (in this example, 8) protrusions 4 and a plurality (in this example, 6) of the protrusions 4 in a substantially ring shape centered around the axis A at the center surrounded by the protrusions 4 '. "" Is arranged. By arranging in this way, the height of the projections 4, 4 ′, 4 ″ is set to decrease from the periphery of the one side surface 3A of the substrate 3 toward the central axis A. When the curved convex portion such as the scalp G is massaged and washed, the tips of the protrusions 4, 4 ′, 4 ″ can easily follow the portion.

  As described above, when the switch 12 is closed, the center of the substrate 3 reciprocates along the axis A, so that the curved concave state bent upward and the curved convex state bent downward. The deformation in which the amplitude becomes 2F is repeated. In this case, when the substrate 3 goes from a flat state to a curved concave state bent upward, the scalp G is placed in a state where the projections 4 provided on the peripheral side of the substrate 3 are in contact with the scalp G. The tip 4B moves inward while being bent, and moves inward while the projections 4 ′ and 4 ″ on the center side are in contact with the scalp G. At this time, the tip 4B is mainly gripped by the tip 4B of the projection 4. At the same time, the hair H as well as the scalp G is washed with a hair wash or the like. Subsequently, when the substrate 3 returns to a flat state and then moves toward a curved convex state bent downward, the protrusion 4 provided on the peripheral side of the substrate 3 is in contact with the scalp G. The scalp G moves outward while the tip 4B is bent, and the thick protrusion 4 'on the center side abuts the scalp G, and then the tip 4B hardly bends in this contact state along the scalp G. Further, after the thin and short projection 4 ″ at the center contacts the scalp G, the tip 4B moves outward while being slightly bent in this contact state, and the projections 4, 4 ′, 4 ″. At the same time, the scalp G is massaged so that the scalp G is pushed and spread by the tips 4B, 4B, 4B, and at the same time, not only the scalp G but also the hair H is washed.

  In this way, the pressing force of the brush part 2 to the scalp G and the tip 4B of the surrounding projection 4 bend in accordance with the movement of the projection 4, so that the scalp G is massaged with a touch that is softly swollen. The protrusions 4 ′ and 4 ″ on the center side move along the scalp G while being slightly bent. Thus, in this embodiment, the protrusions 4 and 4 ′ and 4 ″ are long and / or thick. Therefore, different massage effects can be obtained depending on the locations where the protrusions 4, 4 'and 4' 'are in contact. Further, since the height of the protrusions 4, 4 ′, 4 ″ is set to decrease from the periphery of the one side surface 3A of the substrate 3 toward the center, for example, on the curved convex portion of the top of the scalp G. Since the protrusions 4, 4 ′, 4 ″ are easy to follow, the massage effect on the curved convex portion is excellent.

In addition, this invention is not limited to the above Example, A various deformation | transformation is possible within the range of the summary of invention. For example, in each of the above embodiments, the plurality of protrusions are formed so as to intersect substantially perpendicularly to the surface direction of the substrate, but the plurality of protrusions are slightly inclined with respect to the surface direction of the substrate. You may make it cross. In the second embodiment, the plurality of connecting rods in the reciprocating drive means are set to the same phase, but these phases may be appropriately shifted . Further, in the above embodiments, the shape of the substrate in the brush portion alone was a planar, it is desirable that the shape of the substrate in the brush portion alone has a shape which is convex from the beginning downwardly. This is because, when the flat plate-like substrate is pushed downward by the connecting rod, the connecting rod is swingably connected to the substrate, so that the substrate is pushed obliquely when the connecting rod moves downward. Because it becomes. On the other hand, if the shape of the substrate in the brush unit alone is convex downward from the beginning, and more preferably, if the convex shape is bent to the lowest corresponding to the bottom dead center of the reciprocating drive means, the reciprocating drive When the means moves from the bottom dead center to the top dead center, the substrate is pulled up by the connecting rod, and when the reciprocating drive means moves from the top dead center to the bottom dead center, the restoring force of the substrate The substrate is pushed by the connecting rod at the same time as the substrate returns to the convex state, and the substrate, and thus the brush part, is restored almost uniformly and convex downward, so that the scalp massage etc. It can be done well. The affected area also includes the scalp.

  As described above, the brush device and the massage device according to the present invention can be applied to other uses such as massage and cleaning of the body surface in addition to the scalp.
