[0003] [Patent Document 1] JP 2023-66572 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the massage device of Patent Document 1, the direction of reciprocation of the massage head is perpendicular (at a right angle) to the surface of the body being treated, so for example, when the massage head is brought into contact with the head, it creates vibrations that feel like hitting the head. Because the skin on the head is thin, there is a problem that it is difficult to obtain an effective massage that feels like hitting.

[0005] An object of the present invention is to provide a massager and a massage head of the massager that are capable of comfortably massaging the head of a user. [Means for solving the problem]

[0006] One aspect of the present invention provides a massager comprising a columnar main body extending in a first direction and having a gripping portion on one side in the first direction, a protrusion protruding from the main body, and a massage head attached to the tip of the protrusion so as to be able to vibrate back and forth, wherein the massage head has an attachment portion attached to the protrusion, a base portion extending from the attachment portion toward the opposite side of the main body, and a plurality of protrusions protruding from the base portion to one side of the main body.

[0007] According to one aspect of the present invention, the massage head can massage the scalp by rubbing (sliding) the protrusions, which is comfortable. Compared to impact-like vibrations, the scalp can be moved more widely, and a wider area can be massaged. Effect of the Invention

[0008] The massager and massage head of the massager of the present invention can provide a comfortable massage to the user's head. [Brief description of the drawings]

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the following description is essentially merely illustrative and is not intended to limit the present invention, its applications, or its uses. The drawings are schematic, and the ratios of dimensions, etc., differ from the actual ones.

[0011] The present invention relates to a massager 1 and a massage head 20 of the massager 1. In the following description of the embodiments, terms indicating directions such as "upper", "lower", "left", "right", "front", "back", "height", "width", and "front-rear" refer to directions when the massager 1 is viewed from the front side (the massage head 20 side) unless otherwise specified. Furthermore, the terms "upper-lower direction" and "front-rear direction" used in the following description correspond to the "first direction" and "second direction" in the claims, respectively.

[0012] As shown in Fig. 1, the massager 1 has a main body 11, a protruding portion 12, and a massage head (hereinafter, sometimes referred to as a head) 20. The main body 11 is cylindrical. The main body 11 has a gripping portion 11a provided on one side (lower side) in the up-down direction D1. The main body 11 houses a driving mechanism (not shown) such as a motor and a battery for vibrating the head 20 back and forth between a protruding position P1 and a retracted position P2.

[0013] The protrusion 12 extends in a front-rear direction D2 that is substantially perpendicular (orthogonal) to the up-down direction D1 (first axis D1) of the main body 11 (extending parallel to the second axis D2). In this embodiment, it extends (parallel) along the front-rear direction D2. Note that the term "substantially perpendicular" as used herein includes an intersection at an angle slightly deviated from 90 degrees, and may be, for example, 88 degrees or more and 92 degrees or less. The protrusion 12 is located above the grip 11a (the other side of the up-down direction D1). The protrusion 12 extends forward from the main body 11. The protrusion 12 contains a link member or the like for converting the rotational motion of the drive mechanism into linear motion and transmitting it to the head 20. The protrusion 12 protrudes from the main body 11 by an amount L1 set to 30 mm or more and 45 mm or less. The protrusion amount L1 is the distance from the outer circumferential surface of the main body 11 to the tip 12a of the protrusion 12 in the front-rear direction D2.

[0014] A connecting member 12b is housed inside the protruding portion 12. The connecting member 12b is connected to the link member and has a head 20 attached to its tip. The connecting member 12b is slidable in the front-rear direction D2 (the same direction as the protruding direction of the protruding portion 12) relative to the protruding portion 12. By driving the link member, the connecting member 12b can protrude and retract in the front-rear direction D2 relative to the tip portion 12a of the protruding portion 12.

[0015] The head 20 is removably attached to the tip 12a of the protruding portion 12 so as to be capable of reciprocating motion. More specifically, the head 20 is removably attached to the tip of the connecting member 12b. The head 20 is also attached to the tip of the connecting member 12b so as to be rotatable about the front-rear direction D2 (the protruding axis L12 of the protruding portion 12). The head 20 is adapted to protrude and retract relative to the protruding portion 12 as the connecting member 12b protrudes and retracts. The massager 1 is used by reciprocating the head 20 while pressing it against the part of the user to be massaged (treated). In this embodiment, the head 20 is brush-shaped, and the part to be massaged (part to be massaged) is the head.

[0016] The area to be massaged by the massager 1 (head 20) may be, for example, the head, shoulders, chest, back, abdomen, buttocks, thighs, lower legs, upper arms, lower arms, face, hands, fingertips, etc.

[0017] As shown in FIG. 2, the head 20 has an attachment portion 21 attached to the protruding portion 12, and a brush main body portion 22 extending forward from a tip end 21a of the attachment portion 21.

[0018] The mounting portion 21 is made of synthetic resin and has a hollow cylindrical shape. The mounting portion 21 extends in the front-rear direction D2. The mounting portion 21 is disposed coaxially with the protruding portion 12. A circumferential groove 21b is formed on the outer periphery of the mounting portion 21, and an annular rubber member 21c is attached to the circumferential groove 21b. The connecting member 12b of the protruding portion 12 is connected to the outer periphery of the mounting portion 21.

[0019] The brush body 22 extends forward (opposite the body 11) from the tip 21a of the attachment portion 21. The length direction D3 of the brush body 22 is inclined upward as it approaches the front side in a side view (viewed in the width direction perpendicular to the up-down direction D1 and the front-rear direction D2). In other words, the brush body 22 is formed in an upwardly inclined forward shape that is inclined upward from the base end 22a toward the tip 22b. The brush body 22 has an upper edge line 22c that is approximately parallel to the length direction D3.

[0020] The inclination angle α1 of the brush body 22 with respect to the front-rear direction D2 may be set to 10 degrees or more and 40 degrees or less. More preferably, the inclination angle α1 may be set to 15 degrees or more and 30 degrees or less, and is set to 17 degrees in this embodiment. In this embodiment, the inclination angle α1 of the brush body 22 is the inclination angle of the brush body 22 with respect to the front-rear direction D2, and may be, for example, an angle between the front-rear direction D2 and the length direction D3, or an angle between the front-rear direction D2 and the upper edge line 22c. Alternatively, the inclination angle α1 may be an angle between the brush longitudinal axis L22 of the brush body 22 (which coincides with the length direction D3 in the illustrated example) and the front-rear direction D2 in a side view. Alternatively, the inclination angle α1 can be said to be an angle between the brush longitudinal axis L22 and the protrusion axis L12 of the protrusion 12 (which coincides with the front-rear direction D2 in the illustrated example) in a side view.

[0021] 2 to 5, the brush body 22 will be described. The brush body 22 has a base portion 23 formed integrally with the attachment portion 21, and a brush protrusion portion 24 attached to the lower surface 23d side of the base portion 23.

[0022] 2 and 3, the base portion 23 is made of synthetic resin. The base portion 23 is a plate member having a predetermined thickness in the up-down direction D1. The base portion 23 has a long axis extending along the length direction D3, and is substantially elliptical in bottom view. The base portion 23 is formed so that its width narrows from the base end portion 23a located on the mounting portion 21 side toward the tip end portion 23b. The upper surface 23c and the lower surface 23d of the base portion 23 extend substantially parallel to the length direction D3. In this embodiment, the upper surface 23c of the base portion 23 constitutes the upper edge line 22c of the brush body portion 22.

[0023] At a position of the base end 23a corresponding to the mounting portion 21 (the center of the base portion 23 in the width direction), a bulging portion 23e bulging upward from the upper surface 23c and a disk-shaped vertical wall portion 23h extending downward to connect to the tip portion 21a of the mounting portion 21 are provided. The bulging portion 23e forms a recess when viewed from below. The bulging portion 23e is formed so that its width narrows from the base end 23a side toward the tip portion 23b. The bulging portion 23e is formed integrally and continuously with the front end of the mounting portion 21. The outer diameter of the vertical wall portion 23h is larger than the outer diameter of the mounting portion 21 and is formed so as to roughly match the outer diameter of the connecting member 12b.

[0024] The base portion 23 has a peripheral wall portion 23f extending downward from the outer periphery of the lower surface 23d. The peripheral wall portion 23f is provided along substantially the entire periphery of the base portion 23. The lower surface 23d of the base portion 23 is provided with lattice-shaped ribs 23g, which increase the rigidity of the base portion 23. The height of the ribs 23g (the amount of protrusion downward from the lower surface 23d) is formed to be lower than the peripheral wall portion 23f.

[0025] As shown in FIG. 2, the inclination angle α1 may be the angle of the base portion 23 with respect to the front-to-rear direction D2, or more specifically, the angle formed between the upper surface 23c and / or the lower surface 23d of the base portion 23 and the front-to-rear direction D2 in a side view.

[0026] 2 and 4, the brush protrusion portion 24 is made of silicone rubber. The brush protrusion portion 24 has a brush base 24a attached to the base portion 23, and a plurality of protrusions 25 protruding downward from the brush base 24a. The brush base 24a and the protrusions 25 are integrally formed. In other words, the brush protrusion portion 24 is composed of a single part. The brush base 24a is fixed to the lower surface 23d side of the base portion 23.

[0027] As shown in FIG. 2, the brush base 24a is disposed on the front side of the vertical wall portion 23h. The brush base 24a is a plate member having a predetermined thickness in the up-down direction D1. The upper surface 24d and the lower surface 24e of the brush base 24a extend substantially parallel to the length direction D3. The brush base 24a has a shape corresponding to the base portion 23. The brush base 24a has a major axis extending in the front-rear direction D2, and is substantially elliptical in plan view. The brush base 24a is formed so that its width narrows from the base end portion 24b located on the mounting portion 21 side toward the tip end portion 24c.

[0028] 2 and 4, a padding portion 24f that bulges downward from the lower surface 24e is provided at a position of the base end portion 24b corresponding to the attachment portion 21. The padding portion 24f has a semi-conical shape that gradually narrows from the base end portion 24b toward the tip end portion 24c.

[0029] As shown in Fig. 5, the base end 24b of the brush base 24a is provided with a recess 24g whose periphery is recessed toward the tip end 24c, and the vertical wall 23h (shown in Fig. 3) is fitted into the recess 24g. The rear surface 24j of the padding 24f abuts against the front surface 23i of the vertical wall 23h (shown in Fig. 2).

[0030] As shown in Fig. 5, a stepped portion 24h is formed along the periphery of the brush base 24a on the upper surface 24d side of the brush base 24a. The stepped portion 24h is provided at a position corresponding to the peripheral wall portion 23f (shown in Fig. 3) of the base portion 23. The amount of depression of the stepped portion 24h with respect to the upper surface 24d of the brush base 24a is approximately equal to the difference in height between the peripheral wall portion 23f of the base portion 23 and the rib 23g (shown in Fig. 3).

[0031] As shown in FIG. 2, when the brush protrusion portion 24 is assembled to the base portion 23, the lower surface of the peripheral wall portion 23f abuts against the upper surface of the stepped portion 24h, and the lower surface of the rib 23g of the base portion 23 abuts against the upper surface 24d of the brush base portion 24a.

[0032] As shown in Fig. 5, the upper surface 24d of the brush base 24a is formed with a lattice-like partitioned hollowed-out portion 24i. The hollowed-out portion 24i is a plurality of recesses formed by depressing the upper surface 24d downward. This reduces the weight of the entire head 20 compared to a case in which the hollowed-out portion 24i is not provided.

[0033] As shown in FIG. 2, the inclination angle α1 may be the angle of the brush base 24a with respect to the front-to-rear direction D2, or more specifically, the angle formed between the upper surface 24d and / or the lower surface 24e of the brush base 24a and the front-to-rear direction D2 in a side view.

[0034] As shown in Fig. 2, the multiple protrusions 25 protrude downward and toward the side from the lower surface 24e of the brush base 24a. Each protrusion 25 extends in a direction perpendicular to the lower surface 24e of the brush base 24a. In other words, the height direction D4 of each protrusion 25 is a direction perpendicular to the surface of the brush base 24a. The height direction D4 of the protrusions 25 is generally perpendicular to the base portion 23. In further words, the height direction D4 is generally perpendicular to the length direction D3 (the brush longitudinal axis L22) in a side view. Here, "approximately perpendicular" refers to a range of 88 degrees or more and 92 degrees or less.

[0035] 4, each protrusion 25 is a pyramidal protrusion in which the area in a bottom view, i.e., the cross-sectional area in a cross section perpendicular to the height direction D4, gradually decreases with increasing distance from the brush base 24a, and in this embodiment, the protrusion is conical. In this embodiment, the height of the multiple protrusions 25 (the amount of protrusion from the lower surface 24e of the brush base 24a) is approximately constant.

[0036] The multiple protrusions 25 are arranged such that the tops 25a of adjacent protrusions 25 are offset from each other in the front-rear and width directions. This makes it possible to arrange more protrusions while avoiding interference between the protrusions 25, compared to when the tops 25a of the protrusions 25 are arranged side by side in the width direction.

[0037] 2, an imaginary line 25b connecting the apexes 25a of the projections 25 in the longitudinal direction D3 is generally parallel to the lower surface 24e of the brush base 24a in a side view. Therefore, the inclination angle α1 may be the angle between the imaginary line 25b connecting the apexes 25a in a side view and the front-rear direction D2 (the second axis D2).

[0038] In addition, although not shown, in another embodiment, the brush longitudinal axis L22 of the brush body 22 may be parallel to the protrusion axis L12 of the protrusion 12 in a side view. In other words, the inclination angle α1 may be 0 degrees or more and 10 degrees or less. In other words, in the present invention, the inclination angle α1 may be any angle as long as it is 0 degrees or more and 40 degrees or less.

[0039] The present invention is free to change the design, and the protrusion 12 may be provided in an upwardly inclined forward direction from the main body 11. The brush longitudinal axis L22 of the brush main body 22 may be provided parallel to the protrusion axis L12 of the protrusion 12 inclined forward and upward.

[0040] In other words, in the present invention, as shown in Fig. 1, the angle θ between the longitudinal axis La of the grip portion 11a and the protruding axis L25 of the protrusion 25 in a side view is set to 0 degrees or more and 40 degrees or less, preferably 10 degrees or more and 40 degrees or less, and more preferably 15 degrees or more and 30 degrees or less. If it is less than the lower limit, the grip portion 11a will be too close to the user's head, making it difficult to use. If it exceeds the upper limit, it will be necessary to raise the arm holding the grip portion 11a significantly upward, making it difficult to use.

[0041] In other words, in the present invention, the angle between the brush longitudinal axis L22 and the longitudinal axis La of the grip portion 11a is preferably 90 degrees or more and 130 degrees or less, more preferably 100 degrees or more and 130 degrees or less, and even more preferably 105 degrees or more and 120 degrees or less. If it is less than the lower limit, the grip portion 11a will be too close to the user's head, making it difficult to use. If it exceeds the upper limit, it will be necessary to raise the arm holding the grip portion 11a significantly upward, making it difficult to use.

[0042] The above configuration provides the following effects.

[0043] (1) In a massager 1 having a columnar main body 11 extending in a vertical direction D1 and having a gripping portion 11a on its downward side, a protrusion 12 protruding from the main body 11, and a massage head 20 attached to the tip 12a of the protrusion 12 so as to be capable of reciprocating vibration, the massage head 20 has an attachment portion 21 attached to the protrusion 12, a base portion 23 extending forward from the attachment portion 21, and a plurality of protrusions 25 protruding from the base portion 23 downward of the main body 11.

[0044] According to one aspect of the present invention, the massage head 20 can be comfortably massaged by rocking (sliding) the tips of the projections 25 as if rubbing the scalp. Conventional massage heads vibrate like hitting the head when trying to bring the massage head into contact with the head, and since the skin is thin, it is difficult to obtain a massage effect. However, according to one aspect of the present invention, the scalp can be moved more than with conventional vibrations like hitting, and a wide range can be massaged. The massage head 20 can comfortably massage the user's head, and is easy to bring into contact with the head.

[0045] (2) The massage head 20 is inclined upward as it approaches the front side.

[0046] According to this configuration, the massage head 20 is inclined in a direction away from the gripping portion 11a of the main body 11, so that the space S between the massage head 20 and the gripping portion 11a can be enlarged in the massager 1 shown by the solid line, compared to the case where the massage head 20 extends along the front-rear direction D2 as shown by the two-dot chain line in FIG. 6. As a result, even when the massage head 20 is abutted against the head H, the hand of the user holding the gripping portion 11a is unlikely to interfere with the head H. The massage head 20 is attached so as to extend in the front-rear direction D2 perpendicular to the main body 11 and vibrates back and forth along the front-rear direction D2, so that it is easy to massage the massage target parts other than the head H. In addition, the inclination allows the protrusions 25 to be pressed against the surface of the body to be treated, such as the scalp, while rubbing it.

[0047] (3) The massage head 20 is inclined with respect to the front-to-back direction D2 which is generally perpendicular to the up-down direction D1, and the inclination angle α1 of the massage head 20 with respect to the front-to-back direction D2 is the angle of the base portion 23 with respect to the front-to-back direction D2 and is set to be greater than or equal to 10 degrees and less than or equal to 40 degrees.

[0048] This configuration allows the inclination angle α1 of the massage head 20 to be appropriately set. When the inclination angle α1 is 10 degrees or more, the space S between the massage head 20 and the gripping part 11a can be further secured compared to when the inclination angle α1 is less than 10 degrees. When the inclination angle α1 exceeds 40 degrees, it becomes difficult to bring the massage head 20 into contact with the head H, and the arm must be raised significantly.

[0049] (4) The multiple protrusions 25 are pyramidal protrusions whose cross-sectional area in a bottom view gradually decreases with increasing distance from the base portion 23, and the height direction D4 of the pyramidal protrusions is approximately perpendicular to the base portion 23.

[0050] According to this configuration, the projections 25 can be brought into contact with the head more easily than when the height direction D4 of the projections 25 extends in the vertical direction.

[0051] (5) A massage head 20 is attached to the protruding portion 12 of a massager 1 having a columnar main body portion 11 extending in the vertical direction D1 and having a grip portion 11a on the downward side, and a protruding portion 12 protruding from the main body portion 11, the massage head 20 having an attachment portion 21 attached to the protruding portion 12, a base portion 23 extending forward from the attachment portion 21, and a plurality of protrusions 25 protruding downward from the base portion 23.

[0052] According to this configuration, similar to the massager 1, it is possible to massage the user's head comfortably.

[0053] (6) The base portion 23 inclines upward as it moves forward from the attachment portion 21.

[0054] According to this configuration, similarly to the massager 1, a massage can be performed by rubbing the protrusions 25 against the surface of the body to be treated, such as the scalp, while being pressed against the surface of the body to be treated, due to the inclination.

[0055] In the present embodiment, the protrusion 25 is described as being conical, but the present invention is not limited to this. For example, the protrusion 25 may be cylindrical.

[0056] In this embodiment, the brush main body 22 has been described as having a configuration in which the base portion 23 and the brush protrusions 24 are separate bodies, but the base portion and the brush protrusions may be integrated.

[0057] The present invention is not limited to the configurations described in the above embodiments, and various modifications are possible.
