[Figure 6] This is an overall longitudinal cross-sectional view of the acupressure device according to the second embodiment. [Figure 7] Figure 6 is a first overall longitudinal cross-sectional view showing the operating state of the acupressure device. [Figure 8] Figure 6 is a second overall longitudinal cross-sectional view showing the operating state of the acupressure device. [Modes for carrying out the invention]

[0017] The acupressure device according to the embodiments (the first and second embodiments) is a device mainly for efficiently transmitting a pressing force approximate to finger pressing to a predetermined part of the user's body other than the face, such as meridians (acupoints), to relieve tension in said part. When muscles at a predetermined part of the body are stimulated, increased blood flow and promoted blood circulation in the muscles are induced, and effects such as fatigue recovery, improvement of swelling, and body slimming are expected.

[0018] Fig. 1 is an overall perspective view of the acupressure device 1 according to the first embodiment, and Fig. 2 is an overall side view of the acupressure device 1 according to the first embodiment. The acupressure device 1 includes a main body portion 2 and an acupressure pin 3 protruding from one end side 4 of the main body portion 2 and slidably moving forward and backward relative to the main body portion 2. The acupressure pin 3 abuts against a predetermined part of the user's body, and said part is pressed. In the embodiment, the tip end 6 of the acupressure pin 3 is hemispherical, which makes it less likely to cause pain when pressing (abutting) against the body surface.

[0019] The main body portion 2 has a circular cross section, and the main body portion 2 is mainly integrated by joining three members. The main body portion 2 has an arrangement configuration of a first cylindrical portion 10, a second cylindrical portion 20 directly above in the drawing, and a third cylindrical portion 30 further directly above in the drawing, from the side closer to the acupressure pin 3. An internal space is formed in each of the first cylindrical portion 10, the second cylindrical portion 20, and the third cylindrical portion 30, and necessary members are accommodated therein (see Figs. 3 to 5).

[0020] In the main body portion 2, the third cylindrical portion 30 is disposed on the other end side 5 opposite to the one end side 4 where the acupressure pin 3 is provided. The third cylindrical portion 30 is provided with a grip portion 31. When the user grips the acupressure device 1 and tries to press the acupressure pin 3 against a predetermined part of the body, the user grips the grip portion 31. The grip portion 31 has a chamfered shape, and has low resistance when gripped by hand.

[0021] Furthermore, the grip portion 31 is provided with an expanded diameter portion 32 that protrudes from the main body portion 2 (first cylindrical portion 10, second cylindrical portion 20). The presence of the expanded diameter portion 32 fills the space formed by the palm of the hand when the user curls their hand. As a result, when the user curls their hand to grip the acupressure device 1, the grip of the main body portion 2 becomes easier to hold. In particular, ensuring the stability of the main body portion 2 of the acupressure device 1 is important because the user firmly grips the grip portion 31 and applies force to press the acupressure pins 3 of the acupressure device 1 towards a designated part of the body. Therefore, the expanded diameter portion 32 of the grip portion 31 conforms to the shape of the hand when it is curled during use, contributing to the ease of holding, stability, and maneuverability of the acupressure device 1.

[0022] Figure 3 is an overall longitudinal cross-sectional view of the acupressure device 1 according to the first embodiment. As can be seen from Figure 3, the acupressure pin 3 protrudes from one end 4 of the first cylindrical portion 10 of the main body 2. The acupressure pin 3 is inserted into the pin hole 12 of the first cylindrical portion 10. The acupressure pin 3 is slidable back and forth relative to the user's body (body surface) that is the target of the pressure.

[0023] The inner end 7 of the pressure point pin 3 is located within the first space 13 of the first cylindrical portion 10, and a contact pin 11 is provided that abuts against the pressure point pin 3. A first spring 41 is provided that biases the contact pin 11 toward the pressure point pin 3. In the illustrated embodiment, the contact pin 11 is slender and has a frustoconical shape, and the first spring 41 is positioned to surround the contact pin 11 on its side surface. The contact portion 15 of the contact pin 11 is the bottom of the frustoconical shape, and the contact portion 15 abuts against the inner end 7 of the pressure point pin 3. The first spring 41 contacts the upper end of the first space 13 of the first cylindrical portion 10, and at the same time, the first spring 41 also contacts the contact portion 15 of the contact pin 11. As a result, the contact pin 11 is pressed downward toward the first cylindrical portion 10 by the biasing force of the first spring 41. As a result, the acupressure pin 3 is constantly biased to protrude from the main body 2 (first cylindrical part 10).

[0024] The tip 16 of the contact pin 11, which is the opposite side of the contact portion 15 of the contact pin 11 and is the tip of the frustocone, can enter the restricting portion 17 of the first cylindrical portion 10. The restricting portion 17 is a cylindrical hole structure intended to restrict the sliding direction of the contact pin 11. Because the tip 16 of the contact pin 11 enters the hole of the restricting portion 17, the axis in the direction of movement (up and down) when the contact pin 11 moves forward and backward (up and down movement in the figure) becomes less likely to wobble. In addition, a tapered portion 14 is formed around the restricting portion 17 formed in the first cylindrical portion 10. The tapered portion 14 is a conical inclined surface. When the contact pin 11 rises (upward in the figure), the tip 16 of the contact pin 11 may temporarily come into contact with the inclined surface of the tapered portion 14, and the tip 16 is guided into the hole of the restricting portion 17 while moving along the inclined surface of the tapered portion 14. Therefore, when the contact pin 11 rises, the tip 16 of the contact pin 11 can be reliably entered into the hole of the restricting portion 17.

[0025] The situation in which the tip 16 of the contact pin 11 is guided into the restricting portion 17 is further explained as follows. An inclined surface of the tapered portion 14 is formed up to the hole in the restricting portion 17. The first spring 41 is compressed so that the tip 16 of the contact pin 11 is pressed against the inclined surface of the tapered portion 14. The first spring 41 is compressed, and the compression continues, guiding the tip 16 of the contact pin 11 into the hole in the restricting portion 17. At the moment the tip 16 enters the hole in the restricting portion 17, the resistance to the tip 16 disappears, and accompanied by the biasing force due to the compression accumulated in the first spring 41, the tip 16 of the contact pin 11 enters the hole in the restricting portion 17 in one go. In other words, the anti-retraction action of the acupressure pin 3 involves both a gradual retraction in the initial stage and a rapid retraction in the next stage.

[0026] A biasing block 21 is provided within the second space 23 of the second cylindrical portion 20, which is connected to the upper part of the first cylindrical portion 10, to bias the lower contact pin 11 and the pressure pin 3. A second spring 42 is provided within the third space 33 of the third cylindrical portion 30, which is connected to the upper part of the second cylindrical portion 20, to bias the biasing block 21 toward the pressure pin 3 side (downward in the figure). In the pressure device 1 of this embodiment, an inner cylindrical portion 24 is provided that covers the second space 23 and the third space 33 from the second cylindrical portion 20 to the third cylindrical portion 30. The biasing block 21 and the second spring 42 are housed inside the inner cylindrical portion 24.

[0027] In the acupressure device 1 of this embodiment, the contact pin 11, the first spring 41, the biasing block 21, and the second spring 42 are housed inside the main body 2. That is, the drive parts related to the acupressure pin 3 are not exposed to the outside. Therefore, problems such as the drive parts getting caught on the user's hand or clothing getting caught are avoided, and safety is enhanced. In addition to the coil springs (string springs) of the illustrated embodiment, the first spring 41 and the second spring 42 may also be replaced with bamboo shoot springs or the like. The acupressure device 1 is equipped with springs of optimal performance and shape according to the biasing force such as the pressing force of the acupressure pin 3.

[0028] The biasing block 21 functions as a weight member 22 and is a metal member with an appropriate mass that generates an accelerating force during vertical movement. The biasing block 21 connects with the contact pin 11 when biasing the contact pin 11 (see Figure 5). Thereafter, receiving the biasing force of the second spring 42, the downward load of the biasing block 21 and its downward inertia are transmitted to the contact pin 11 side.

[0029] Furthermore, the biasing block 21 has an entry hole 26 formed as a connecting part. The entry hole 26 of the connecting part receives the tip 16 of the contact pin 11, making the connection between the biasing block 21 and the contact pin 11 more secure.

[0030] The operation of the acupressure device 1 according to the first embodiment will now be explained using the longitudinal cross-sectional views in Figures 4 and 5. The cross-sectional view in Figure 4 shows the beginning of use of the acupressure device 1. The user grasps the bulging portion 32 of the grip portion 31 of the acupressure device 1 with their hand, brings the acupressure pin 3 into contact with a predetermined part of the body, and presses the desired predetermined part of the body with appropriate force. At this point, the acupressure pin 3 retracts into the first cylindrical portion 10 of the main body portion 2 (moves upward in the plane of the paper and rises). In conjunction with the movement of the acupressure pin 3, the contact pin 11 also retracts into the first cylindrical portion 10 (moves upward in the plane of the paper and rises). At this time, the first spring 41 that biases the contact pin 11 is compressed more than its initial state (see Figure 3).

[0031] The tip 16 of the contact pin 11 may, in some cases, come into contact with the inclined surface of the tapered portion 14, and the tip 16 is guided into the hole of the restricting portion 17 while moving along the inclined surface of the tapered portion 14. Then, the tip 16 protrudes from the hole of the restricting portion 17. At this time, due to the inertia associated with the mass of the biasing block 21 (weight member 22), the biasing block 21 tries to remain in its original position (see Figure 3). At this point, the user is pressing the acupressure device 1 with their hand toward a predetermined part of their body. Therefore, the second spring 42 is compressed between the inertia generated in the biasing block 21 (the force that tries to keep it in place) and the downward movement of the third cylindrical portion 30 of the main body 2.

[0032] The cross-sectional view in Figure 5 shows the acupressure device 1 in use. As explained in Figure 4, the second spring 42 is compressed. Subsequently, the second spring 42 rebounds against the compression. Due to the rebound of the second spring 42, the biasing block 21 (weight member 22) is finally pushed back by the second spring 42 and moves forward (moves downward in the plane of the paper, descending). At this time, the tip 16 of the contact pin 11 enters the entry hole 26 of the joint formed in the biasing block 21 (weight member 22), and the two are connected.

[0033] Therefore, the biasing force of the second spring 42 attempting to extend, the mass of the biasing block 21 (weight member 22) itself, and the inertia of the biasing block 21 as it moves under the biasing force of the second spring 42 are all transmitted to the contact pin 11 at once. As a result of the combination of these forces, an impact occurs on the contact pin 11 in the forward direction (downward on the plane of the paper, downward direction). In other words, when the second spring 42 is compressed, the contact pin 11 and the pressure pin 3 are pressed by the inertia of the biasing block 21 accompanying the biasing force of the second spring 42. The inertia of the biasing block 21 is reliably transmitted toward the contact pin 11 through the connection between the entry hole 26 of the joint and the tip 16 of the contact pin 11, and the contact pin 11 and the pressure pin 3 are pressed in the forward direction (downward on the plane of the paper, downward direction). Since the contact pin 11 and the pressure pin 3 are in direct contact, the impact generated from the biasing block 21 to the contact pin 11 is directly transmitted to the pressure pin 3.

[0034] Figure 6 is an overall longitudinal cross-sectional view of the acupressure device 1x of the second embodiment, and Figures 7 and 8 are overall longitudinal cross-sectional views showing the operating state of the acupressure device 1x of the second embodiment. In the acupressure device 1x of the second embodiment, the same reference numerals are used for structures and parts that are common to the acupressure device 1 of the first embodiment described above. In the acupressure device 1x of the second embodiment, the first cylindrical portion 10 is composed of two members: a front first cylindrical portion 10a and a rear first cylindrical portion 10b. The front first cylindrical portion 10a and the rear first cylindrical portion 10b are integrated by screwing together the threaded portion 51 of the front first cylindrical portion 10a and the threaded groove portion 52 of the rear first cylindrical portion 10b. Furthermore, the second cylindrical portion 20 is fixed to the first cylindrical portion 10 by screwing the threaded portion 53 formed on the rear first cylindrical portion 10b with the threaded groove portion 54 of the second cylindrical portion 20, and the third cylindrical portion 30 (grip portion 31) is fixed to the first cylindrical portion 10 by screwing the threaded portion 53 on the rear first cylindrical portion 10b with the threaded groove portion 55 inside the third cylindrical portion 30 (grip portion 31), thereby firmly integrating the components that make up the exterior of the acupressure device 1x in the second embodiment.

[0035] As can be seen from Figure 6, the acupressure pin 3 protrudes from one end 4 of the first cylindrical portion 10 (front first cylindrical portion 10a) of the main body portion 2. The acupressure pin 3 is inserted into the pin hole 12 of the first cylindrical portion 10. The acupressure pin 3 is slidable back and forth relative to the user's body (body surface) that is the target of the pressure.

[0036] The inner end 7 of the pressure point pin 3 is located within the first space 13 of the first cylindrical portion 10, and a contact pin 11 is provided that abuts against the pressure point pin 3. A first spring 41 is provided that biases the contact pin 11 toward the pressure point pin 3. In the illustrated second embodiment, the first spring 41 is positioned around the contact pin 11 on its side surface. The contact portion 15 of the contact pin 11 is the bottom, and the contact portion 15 abuts against the inner end 7 of the pressure point pin 3. The first spring 41 contacts the upper end of the first space 13 of the first cylindrical portion 10 (rear first cylindrical portion 10b), and at the same time, the first spring 41 also contacts the contact portion 15 of the contact pin 11. As a result, the contact pin 11 is pressed downward toward the first cylindrical portion 10 by the biasing force of the first spring 41. As a result, the acupressure pin 3 is constantly biased to protrude from the main body 2 (first cylindrical part 10).

[0037] On the opposite side of the contact portion 15 of the contact pin 11, that is, within the first cylindrical portion 10 (rear first cylindrical portion 10b), around the tip portion 16 of the contact pin 11, which is the tip of a frustocone, a regulating ring 18 is provided to restrict the direction of movement of the contact pin 11. A regulating portion 17 is formed in the regulating ring 18, and the tip portion 16 of the contact pin 11 can enter the regulating portion 17. The regulating portion 17 is a cylindrical hole structure intended to restrict the sliding direction of the contact pin 11. Since the tip portion 16 of the contact pin 11 enters the hole in the regulating portion 17, the axis in the direction of movement (vertical direction) when the contact pin 11 moves forward and backward (up and down movement in the figure) becomes less likely to wobble.

[0038] Furthermore, a tapered portion 14 is formed around the restricting portion 17 formed within the first cylindrical portion 10 (rear first cylindrical portion 10b). The tapered portion 14 is a conical inclined surface. When the contact pin 11 rises (upward as shown in the figure), the tip portion 16 of the contact pin 11, depending on its length, may come into contact with the inclined surface of the tapered portion 14, and the tip portion 16 is guided into the hole of the restricting portion 17 while traveling along the inclined surface of the tapered portion 14. Therefore, when the contact pin 11 rises, the tip portion 16 of the contact pin 11 can be reliably entered into the hole of the restricting portion 17.

[0039] The situation in which the tip 16 of the contact pin 11 is guided into the restricting portion 17 is described as follows, similar to the case of the acupressure device 1 of the first embodiment. The inclined surface of the tapered portion 14 is formed up to the hole in the restricting portion 17. Depending on the length of the tip 16 of the contact pin 11, the first spring 41 is compressed as the tip 16 is pushed against the inclined surface of the tapered portion 14. The first spring 41 is compressed, and the compression continues, guiding the tip 16 of the contact pin 11 into the hole in the restricting portion 17. At the moment the tip 16 enters the hole in the restricting portion 17, there is no resistance to the tip 16, and accompanied by the biasing force due to the compression accumulated in the first spring 41, the tip 16 of the contact pin 11 enters the hole in the restricting portion 17 in one go. In other words, the anti-retraction action of the acupressure pin 3 involves both a gradual retraction in the initial stage and a rapid retraction in the next stage.

[0040] The upper part of the first cylindrical portion 10 (rear first cylindrical portion 10b) is provided with a biasing block 21 that biases the lower contact pin 11 and the pressure point pin 3. Furthermore, a second spring 42 that biases the biasing block 21 toward the pressure point pin 3 (downward in the figure) is provided in a cylindrical third space 33 formed inside the threaded portion 53 of the rear first cylindrical portion 10b. In the pressure point massager 1x of the second embodiment, the biasing block 21 and the second spring 42 are housed in the cylindrical third space 33 formed inside the threaded portion 53 of the rear first cylindrical portion 10b.

[0041] In the acupressure device 1x of the second embodiment, the contact pin 11, the first spring 41, the biasing block 21, and the second spring 42 are housed inside the main body 2. In other words, the drive parts related to the acupressure pin 3 are not exposed to the outside. Therefore, problems such as the drive parts getting caught on the user's hand or clothing getting caught are avoided, and safety is enhanced. Note that in addition to the coil springs (string springs) of the illustrated embodiment, the first spring 41 and the second spring 42 may also be replaced with bamboo shoot springs or the like. The acupressure device 1 is equipped with springs of optimal performance and shape according to the biasing force such as the pressing force of the acupressure pin 3.

[0042] The biasing block 21 functions as a weight member 22 and is a metal member with an appropriate mass that generates an accelerating force during vertical movement. The biasing block 21 connects with the contact pin 11 when biasing the contact pin 11 (see Figure 7). Thereafter, receiving the biasing force of the second spring 42, the downward load of the biasing block 21 and its downward inertia are transmitted to the contact pin 11 side. Furthermore, an entry hole 26 is formed in the biasing block 21 as a connecting part. The entry hole 26 of the connecting part receives the tip 16 of the contact pin 11, making the connection between the biasing block 21 and the contact pin 11 more secure.

[0043] The operation of the acupressure device 1x in the second embodiment will now be explained using the longitudinal cross-sectional views in Figures 7 and 8. The cross-sectional view in Figure 7 shows the beginning of use of the acupressure device 1. The user grasps the bulging portion 32 of the grip portion 31 of the acupressure device 1 with their hand, brings the acupressure pin 3 into contact with a predetermined part of the body, and presses the desired predetermined part of the body with appropriate force. As a result, the acupressure pin 3 retracts into the first cylindrical portion 10 (front first cylindrical portion 10a) of the main body portion 2 (moves upward in the plane of the paper and rises). In conjunction with the movement of the acupressure pin 3, the contact pin 11 retracts into the first cylindrical portion 10 (rear first cylindrical portion 10b) (moves upward in the plane of the paper and rises). At this time, the first spring 41 that biases the contact pin 11 is compressed more than its initial state (see Figure 6).

[0044] The tip 16 of the contact pin 11 slides without wobbling due to the restricting portion 17 on the inner circumference of the restricting ring 18, and the tip 16 protrudes from the restricting ring 18. At this time, due to the inertia associated with the mass of the biasing block 21 (weight member 22), the biasing block 21 tries to remain in its original position (see Figure 3). At this point, the user is pressing the acupressure device 1 with their hand toward a predetermined part of their body. Therefore, the second spring 42 is compressed between the inertia generated in the biasing block 21 (the force that tries to keep it in place) and the downward movement of the third cylindrical portion 30 of the main body 2.

[0045] The cross-sectional view in Figure 8 shows the acupressure device 1x in use. As explained in Figures 6 and 7, the second spring 42 is compressed. Subsequently, the second spring 42 rebounds against the compression. Due to the rebound of the second spring 42, the biasing block 21 (weight member 22) is finally pushed back by the second spring 42 and moves forward (moves downward in the plane of the paper). At this time, the tip 16 of the contact pin 11 enters the entry hole 26 of the joint formed in the biasing block 21 (weight member 22), and the two are connected.

[0046] Therefore, the biasing force of the second spring 42 attempting to extend, the mass of the biasing block 21 (weight member 22) itself, and the inertia of the biasing block 21 as it moves under the biasing force of the second spring 42 are all transmitted to the contact pin 11 at once. As a result of the combination of these forces, an impact occurs on the contact pin 11 in the forward direction (downward on the plane of the paper, downward direction). In other words, when the second spring 42 is compressed, the contact pin 11 and the pressure pin 3 are pressed by the inertia of the biasing block 21 accompanying the biasing force of the second spring 42. The inertia of the biasing block 21 is reliably transmitted toward the contact pin 11 through the connection between the entry hole 26 of the joint and the tip 16 of the contact pin 11, and the contact pin 11 and the pressure pin 3 are pressed in the forward direction (downward on the plane of the paper, downward direction). Since the contact pin 11 and the pressure pin 3 are in direct contact, the impact generated from the biasing block 21 to the contact pin 11 is directly transmitted to the pressure pin 3.

[0047] As can be understood from the series of explanations, in addition to the force applied when the acupressure device 1, 1x is pressed against a designated part of the body, an impact force generated from within the acupressure device 1, 1x is also applied. Therefore, the shock wave is more easily transmitted through the acupressure device 1 to the deep muscles of the body, and the effect of the massage is further enhanced.

[0048] There are no particular restrictions on the areas to massage using the acupressure device 1, 1x. For example, (1) in the case of the pectoralis minor (pectoralis major), the stimulation point is on the extension of the line below the clavicle where it meets the shoulder bone. (2) in the case of the rectus abdominis (end of the rib cage), the stimulation point is from the end of the bone on the solar plexus side to the end of the flank. (3) in the case of the gluteus maximus and gluteus medius, the stimulation point is the slightly indented area diagonally above the top of the crease of the buttocks.

[0049] The acupressure devices 1 and 1x are sized and shaped to fit comfortably in the hand, allowing the user to easily, safely, and efficiently stimulate specific points on the body. Through the acupressure devices 1 and 1x, muscle massage through pressure and shock waves generated by the movement of the second spring 42 and biasing block 21 are applied to the acupressure pin 3. As a result, vibrations that cannot be formed by mere pressure from the device alone are transmitted as stimulation to specific points on the body. In addition, the acupressure device 1 does not use electricity for electrical stimulation or motor drive, and can apply pressure and stimulation to the body through the user's movements and the action of components such as springs and weights. This results in excellent durability of the acupressure device 1 itself and a simplified internal mechanism. [Explanation of symbols]
