Description

[Technical field]

[0001] The present invention relates to a massage device that applies vibrations to the body of a user. [Background technology]

[0002] Massage devices that apply vibrations to the user's body to massage have been known for some time. By applying vibrations to the body using such a massage device, it is possible to obtain effects such as relieving muscle stiffness and promoting blood circulation. One of the massage devices that applies vibrations to the body in this way is disclosed in, for example, Utility Model Registration No. 3237623.

[0003] Since small massage devices are portable, they can be easily used in various places around the home, and can also be used on the go. Furthermore, since small massage devices can be held in the hand, they can be used to massage various parts of the body by applying vibrations.

[0004] Also, there are known small massage devices that can be used by changing several types of attachments with different shapes, hardness, etc. Massage devices that allow exchange of attachments can apply vibrations using attachments suitable for each part of the body, thereby improving the effect of the massage. Furthermore, since the attachments can be changed according to the user's physical condition and mood on that day, it is expected that the user's satisfaction will be increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the following examples, and various modifications are possible as long as they have substantially the same configuration as the present invention and provide similar operational effects. EXAMPLES

[0013] Fig. 1 and Fig. 2 are respectively a perspective view and a side view showing a massage device according to the present embodiment, and Fig. 3 is a view showing a schematic bottom surface of the massage device according to the present embodiment.

[0014] In the description of the massage device, the front-rear direction of the massage device is the direction along which the attachment shown in Fig. 7 vibrates when the attachment is connected to the device main body. For example, in Fig. 2, the front-rear direction of the massage device is the left-right direction on the paper. In this case, in the front-rear direction, the direction in which the attachment is pulled when removing it from the connection part of the device main body, which will be described later, is the front, and the direction in which the attachment is inserted into the connection part and attached is the rear.

[0015] The up-down direction of the massage device is the direction along which a grip part (described later) of the massage device extends, and is the up-down direction on the paper surface of Fig. 2. The left-right direction of the massage device is the direction perpendicular to the front-rear direction and the up-down direction, and is the front-rear direction on the paper surface of Fig. 2.

[0016] The massage device 1 of this embodiment is a small massage device 1 that can be held and used by a user in one hand. The massage device 1 has a device main body 10 and a plurality of attachments 60 that are removably attached to the device main body 10.

[0017] The device main body 10 has a substantially T-shape in a side view (FIG. 2) of the massage device 1. The device main body 10 has an intersection 11 which is the starting point of the three branches, a forward extension portion 12 which extends forward from the intersection 11, a grip portion 13 which extends downward from the intersection 11, and a motor housing portion 14 which extends upward from the intersection 11 and houses a motor 23 therein. The grip portion 13 is a portion which a user mainly holds with his / her hand when using the massage device 1.

[0018] In this embodiment, the forward extension 12, the grip portion 13, and the motor housing portion 14 are each formed to have a thickness that is easy to grip with a human hand. In particular, the base end portion 12a of the forward extension 12 on the side that connects to the intersection portion 11, the grip portion 13, and the motor housing portion 14 are each formed to have the same or approximately the same thickness.

[0019] When using the massage device 1, the user can hold the grip portion 13 with his / her hand and bring the attachment 60 connected to the device main body 10 into contact with a part of the body. Furthermore, in this embodiment, the above-mentioned parts of the device main body 10 are formed with a thickness that makes them easy to hold with a human hand, so that the user can easily hold various parts of the device main body 10. This makes it easier for the user to hold the massage device 1 in an appropriate position with one hand depending on the part of the body to which the attachment 60 is to be brought into contact, and makes it easier for the attachment 60 to be brought into contact with the body with an appropriate force. This improves the ease of use of the massage device 1.

[0020] The device main body 10 of this embodiment has a cover case 21 with a space inside, a connection part 30 provided in the forward extension part 12, an operation part 40 provided on the bottom part of the grip part 13, and a control part (not shown) provided in the cover case 21 and performing various controls of the massage device 1.

[0021] Inside the cover case 21, there are provided a first space 22 (see Figs. 4 and 5) formed in the front-rear direction across the intersection 11 and the forward extension 12, a second space formed in the grip portion 13, and a third space formed in the motor housing portion 14. In the first space 22 of the cover case 21, a transmission portion 50 that converts the rotational motion of the motor 23 into linear reciprocating motion and transmits it to the connection portion 30, and the connection portion 30 that connects the attachment 60 are installed and housed. A rechargeable battery is fixed in the second space. The motor 23 is fixed in the third space.

[0022] The transmission unit 50 of this embodiment has an eccentric rotating unit (not shown) connected to the rotating shaft 23a of the motor 23, a rod unit 51 that holds the eccentric rotating unit at its base end (rear end) and is formed long in the front-rear direction, and a connecting pin 52 (see FIG. 5) that is rotatably held at the tip end (front end) 51a of the rod unit 51. The connection unit 30 is connected to the tip end 51a of the rod unit 51 via the connecting pin 52.

[0023] The rotating shaft 23a of the motor 23 is connected to the eccentric rotating part of the transmission unit 50 at a position offset from the position of the central shaft of the eccentric rotating part. Therefore, when the motor 23 is operating, the rotating shaft 23a of the motor 23 rotates, and the eccentric rotating part performs a rotational operation while moving in the front-rear and left-right directions around the rotating shaft 23a of the motor 23.

[0024] In the rod portion 51 of the transmission unit 50, when the motor 23 is operating, the base end (rear end) 51b that holds the eccentric rotation portion of the rod portion 51 rotates while moving in the front-rear and left-right directions, just like the eccentric rotation portion. This allows the tip portion 51a of the rod portion 51 that holds the connecting pin 52 of the rod portion 51 to perform a linear reciprocating motion along the front-rear direction.

[0025] Since the transmission unit 50 has the above-mentioned structure, it can convert the rotational motion of the motor 23 into linear reciprocating motion and transmit it to the connection unit 30, so that the vibration attachment 80 (FIG. 7) connected to the connection unit 30 can be smoothly vibrated in the front-rear direction. Note that in the present invention, the structure and transmission method of the transmission unit are not particularly limited as long as it is possible to convert the rotational motion of the motor into linear reciprocating motion and transmit it.

[0026] The connection part 30 of the device main body 10 is formed to detachably connect one attachment 60. Specifically, as shown in Fig. 4 and Fig. 5, the connection part 30 has a first connection part 31 to which the connecting pin 52 of the transmission part 50 is fixed, a second connection part 32 disposed inside the first connection part 31 and held by the first connection part 31, and a third connection part 33 provided in front of the second connection part 32.

[0027] When the motor 23 is operating, the connection portion 30 (the first connection portion 31, the second connection portion 32, and the third connection portion 33) can perform a linear reciprocating motion along the front-rear direction together with the tip portion 51a of the rod portion 51. In addition, in Figs. 4 and 5, in order to easily show the connection portion 30 of the device main body portion 10, only a part of an insertion shaft portion (insertion portion) 61 (to be described later) of the attachment 60 is illustrated. In this embodiment, the second connection portion 32 and the third connection portion 33 may be directly or indirectly fixed to the cover case 21 so as not to perform a linear reciprocating motion when the motor 23 is operating.

[0028] The first connection part 31 can hold the insertion shaft part 61 of the attachment 60 by inserting the insertion shaft part 61 into the inside of the first connection part 31. Furthermore, the first connection part 31 can vibrate the vibration attachment 80 in the front-rear direction by performing a linear reciprocating motion while holding, for example, the insertion shaft part 61 of a vibration attachment 80 (FIG. 7) in the first connection part 31. The second connection part 32 is disposed inside the first connection part 31 and is connected to the first connection part 31 and the third connection part 33.

[0029] The third connection part 33 has a disk-shaped bottom plate part 33a held by the second connection part 32, and a connection main body part 33b extending forward from the bottom plate part 33a. The connection main body part 33b of the third connection part 33 has a substantially rectangular prism shape that is substantially trapezoidal (particularly, substantially isosceles trapezoidal) when the third connection part 33 is viewed from the front side of the device main body part 10. The connection main body part 33b is formed corresponding to the shape of an auxiliary tube part 74 of the stimulation attachment 70, which will be described later, and is inserted and accommodated in the auxiliary tube part 74 of the stimulation attachment 70 when, for example, the stimulation attachment 70 (FIG. 6) is connected to the device main body part 10.

[0030] A front end surface (tip surface) of the connection body 33b is provided with a plurality of insertion holes 33c into which the energizing pins 75 of the stimulation attachment 70, which will be described later, are inserted. For example, in the case of this embodiment, four insertion holes 33c are provided on the front end surface of the connection body 33b. Inside the connection body 33b, there are provided an electric circuit section (not shown) that transmits power from a rechargeable battery to the stimulation attachment 70 via the energizing pins 75, and a detection section (not shown) that detects that the stimulation attachment 70 is connected to the device body 10 when the energizing pins 75 of the stimulation attachment 70 are inserted into the insertion holes 33c of the connection body 33b. In the present invention, the configuration of the detection section is not particularly limited.

[0031] As shown in FIG. 3, the operation section 40 of the massage device 1 has one operation button 41 arranged on the bottom surface of the grip section 13, four operation lamps 42 arranged around the operation button 41, and a plug insertion port 43.

[0032] The operation button 41 is disposed at the center of the bottom surface of the grip portion 13. For example, when the user presses the operation button 41 for a long time, the power of the massage device 1 can be switched ON / OFF. Also, when the operation button 41 is pressed briefly while the power is ON, the strength level of the operation performed by the attachment 60 can be changed in stages.

[0033] In the massage device 1 of this embodiment, for example, when a stimulation attachment 70 (see Figure 6) that applies electrical stimulation (EMS) to the user's muscles is connected to the connection part 30 of the device main body 10 (i.e., when the stimulation mode described below is being executed), the operation button 41 is set so that when the operation button 41 is pressed while the power is on, the strength of the electrical stimulation applied to the muscles from the stimulation attachment 70 can be changed in four stages.

[0034] In addition, when a vibration attachment 80 (see Figure 7) that imparts vibrations to the user's body is connected to the connection part 30 of the device main body 10 (i.e., when the vibration mode described below is being executed), the operation button 41 is set so that the level of vibration imparted to the user's body from the vibration attachment 80 can be changed in four stages by pressing the operation button 41 with the power turned on.

[0035] That is, although the massage device 1 of this embodiment is formed with only one operation button 41 that is operated to change the level of the operation (strength of electrical stimulation and level of vibration) performed by the attachment 60, the control unit of the massage device 1 can detect the type of the attachment 60 connected to the device main body 10 as described below. Therefore, the single operation button 41 of this embodiment can change the level of operation (strength of electrical stimulation and level of vibration) in stages for each different function of each attachment according to the attachment connected.

[0036] In the operation unit 40 of this embodiment, the four operation lamps 42 are parts that display the level (strength) of the operation performed by the attachment 60, and are formed so that, for example, the number of lamps that are turned on is changed depending on the difference in vibration level. The plug insertion port 43 of the operation unit 40 is a part where, for example, a connection plug of a charging cord of a power source (not shown) is inserted and connected. By inserting a connection plug into this plug insertion port 43, electricity can be supplied from the power source to the rechargeable battery housed in the grip portion 13, thereby charging the rechargeable battery.

[0037] The control unit (not shown) of the massage device 1 has a motor control unit (not shown) that controls the drive of the motor 23, an electrical control unit (not shown) that controls the application of current to the electrode unit 72 (described later) of the stimulation attachment 70, and a detection unit (not shown) that detects that the stimulation attachment 70 has been connected to the connection unit 30 of the device main body 10.

[0038] In the control unit of this embodiment, when, for example, a stimulation attachment 70 is connected to the connection portion 30 of the device main body portion 10, the detection portion of the control unit can detect the connection of the stimulation attachment 70 and select and execute a stimulation mode in which the stimulation attachment 70 generates electrical stimulation in the user's muscles.

[0039] That is, by selecting the stimulation mode as described above, the control unit can maintain the motor 23 stopped and perform various controls including the supply of power to the stimulation attachment 70 according to the conditions selected by the operation button 41 of the operation unit 40. As a result, the stimulation attachment 70 of the massage device 1 can provide an electrical stimulation to the user.

[0040] On the other hand, in the control unit of this embodiment, when the vibration attachment 80 is connected to the connection portion 30 of the device main body 10, the detection portion of the control unit does not detect the connection of the stimulation attachment 70, so that instead of the stimulation mode described above, a vibration mode can be selected and executed in which the vibration attachment 80 is vibrated to impart vibrations to the user's body from the vibration attachment 80.

[0041] In other words, when the vibration mode is selected in the control unit (in other words, when the stimulation mode is not selected), the motor control unit drives the motor 23 according to the conditions selected by the operation button 41 of the operation unit 40, without control by the electrical control unit, thereby enabling the vibration attachment 80 to impart vibration to the user's body.

[0042] As described above, the control unit of this embodiment is configured to be able to detect that the stimulation attachment 70 has been connected to the connection unit 30, and can therefore detect whether the attachment 60 connected to the connection unit 30 is the stimulation attachment 70 or something other than the stimulation attachment 70, and can appropriately select and execute an operating mode that can be performed by the attachment 60 depending on the detection result.

[0043] Next, the attachment 60 to be connected to the device main body 10 will be described. The attachment 60 of this embodiment includes at least a stimulation attachment 70 shown in FIG. 6 and a vibration attachment 80 shown in FIG.

[0044] The stimulation attachment 70 shown in Figure 6 has a pair of left and right electrode portions 72, a base portion 73 supporting the two electrode portions 72, an electrical circuit portion (not shown) provided within the base portion 73, an insertion shaft portion 71 extending from the base portion 73, an auxiliary tube portion 74 arranged within the insertion shaft portion 71, four conductive pins 75 extending into the auxiliary tube portion 74, and an electrical control portion (not shown) that controls the application of current to the electrode portions 72.

[0045] The stimulation attachment 70 is attached to the connection part 30 by inserting the insertion shaft part 71 into the connection part 30 of the device body part 10 from the front side and accommodating it inside the first connection part 31. Furthermore, the stimulation attachment 70 attached to the connection part 30 of the device body part 10 can be easily removed by, for example, grasping the stimulation attachment 70 with a hand and pulling it strongly forward to pull the stimulation attachment 70 out of the connection part 30 of the device body part 10.

[0046] The two electrode units 72 are connected to an electric circuit unit (not shown) provided in the base unit 73, and the electric circuit unit is provided with a means for applying an electric current (alternating current) to the two electrode units 72. This allows the stimulation attachment 70 to stably pass an electric current through the two electrode units 72. Furthermore, the electric circuit unit applies an electric current while both of the two electrode units 72 are in contact with the user's skin, so that the user's muscles can be stably stimulated with electric stimulation. As a result, the user's muscles can easily contract due to the electric stimulation, and a muscle training effect can be obtained.

[0047] In the present invention, the electric circuit section that passes a current through the electrode section 72 is not particularly limited, and may have a conventionally known structure that includes a coil, a resistor, a capacitor, etc. In addition, in the present invention, the structure and method for applying electrical stimulation to the user's muscles from the two electrodes of the stimulation attachment are not particularly limited.

[0048] The insertion shaft portion 71 of the stimulation attachment 70 has a cylindrical shaft bottom portion 71a connected to the base portion 73, and a cylindrical portion 71b extending straight in a cylindrical shape from the shaft bottom portion 71a toward one side (rearward). A space surrounded by the bottom surface of the cylindrical bottom portion and the inner peripheral surface of the cylindrical portion 71b is provided inside the cylindrical portion 71b.

[0049] The auxiliary cylinder portion 74 of the stimulation attachment 70 is provided in the insertion shaft portion 71 and integrally with the insertion shaft portion 71. The auxiliary cylinder portion 74 is disposed parallel to the cylindrical portion 71b from the shaft bottom portion 71a of the insertion shaft portion 71 toward the rear. In a rear view (not shown) of the stimulation attachment 70 seen from the rear, the auxiliary cylinder portion 74 has a cylindrical shape that is substantially trapezoidal (particularly, substantially isosceles trapezoidal) so that the third connection portion 33 of the device main body portion 10 can be inserted inside.

[0050] By forming the auxiliary tube portion 74 in this manner, when connecting the stimulation attachment 70 to the device main body portion 10, the third connection portion 33 of the device main body portion 10 can be inserted into the auxiliary tube portion 74, so that the stimulation attachment 70 can be attached to the device main body portion 10 in a constant orientation and posture.

[0051] Within the auxiliary cylinder 74, four conductive pins 75 protrude rearward from the shaft bottom 71a of the insertion shaft 71 in parallel with the cylindrical portion 71b of the insertion shaft 71 (only two of the four conductive pins 75 are shown in FIG. 6). These four conductive pins 75 are each connected to an electric circuit of the stimulation attachment 70. The four conductive pins 75 are disposed in correspondence with the positions of the four insertion holes 33c provided in the third connection portion 33 of the device body 10.

[0052] As a result, when the third connection part 33 of the device main body 10 is inserted into the auxiliary cylinder part 74, the four conductive pins 75 of the stimulation attachment 70 can be inserted into the four insertion holes 33c of the third connection part 33, respectively. Furthermore, by inserting the four conductive pins 75 into the insertion holes 33c of the third connection part 33 in this manner, the control part of the massage device 1 can detect that the stimulation attachment 70 has been connected to the connection part 30 of the device main body 10, and therefore the control part can stably select and execute the stimulation mode.

[0053] Furthermore, by inserting the four conductive pins 75 into the insertion holes 33c of the third connection part 33, the power of the rechargeable battery housed in the device main body 10 can be supplied to the electric circuit part of the stimulation attachment 70 via the third connection part 33 and the four conductive pins 75. Also, the control part of the massage device 1 (for example, an electric control part included in the control part) can control the current applied to the two electrode parts 72, and the stimulation attachment 70 can apply an electric stimulation to the user according to the condition selected by the operation button 41 of the operation part 40.

[0054] On the other hand, the vibration attachment 80 shown in Fig. 7 is formed as a spherical attachment having a spherically formed attachment main body 82 and an insertion shaft 81 extending rearward from the attachment main body 82. The insertion shaft 81 of the circular vibration attachment 80 has a cylindrical shaft bottom 81a connected to the attachment main body 82, and a cylindrical portion 81b extending straight from the shaft bottom 81a toward the rear in a cylindrical shape, substantially similar to the insertion shaft 71 of the stimulation attachment 70. A space is provided inside the cylindrical portion 81b.

[0055] The circular vibration attachment 80 is attached to the connection part 30 of the device body 10 so as to be capable of vibrating in the front-rear direction by inserting the insertion shaft part 81 into the connection part 30 of the device body 10 from the front side and accommodating it inside the first connection part 31. Furthermore, the vibration attachment 80 attached to the connection part 30 of the device body 10 can be easily removed by, for example, grasping the vibration attachment 80 with a hand and pulling it strongly forward to pull the vibration attachment 80 out of the connection part 30 of the device body 10.

[0056] In addition to the stimulation attachment 70 and the circular vibrating attachment 80 described above, the attachments of the present invention may include other vibrating attachments, such as a conical vibrating attachment in which part of the attachment has a pointed shape that is close to a cone, or a U-shaped vibrating attachment in which part of the attachment has a three-dimensional shape that is approximately U-shaped.

[0057] According to the massage device 1 of this embodiment as described above, for example, when a user connects the stimulation attachment 70 to the connection part 30 of the device main body part 10 and operates the massage device 1, the conductive pin 75 of the stimulation attachment 70 is inserted into the insertion hole 33c of the third connection part 33 of the device main body part 10, so that the control part of the massage device 1 can detect that the stimulation attachment 70 has been connected to the connection part 30.

[0058] As a result, the control unit of the massage device 1 selects and executes a stimulation mode that generates electrical stimulation in the user's muscles as described above, and can supply power from the device main body 10 to the stimulation attachment 70 according to the conditions selected by the user using the operation buttons 41 of the operation unit 40. Furthermore, a current can be applied to the two electrode units 72 from the electric circuit unit of the stimulation attachment 70.

[0059] Therefore, by contacting the two electrode sections 72 of the stimulation attachment 70 with the skin of the body, the user can apply electrical stimulation to the user's muscles under conditions selected by the operation button 41 from the electrode sections 72 of the stimulation attachment 70, thereby training the muscles. In addition, by pressing the operation button 41, the user can easily change the strength of the electrical stimulation applied to the muscles.

[0060] On the other hand, when the user connects the vibration attachment 80 to the connection part 30 of the device main body 10 to operate the massage device 1, the conductive pin 75 is not inserted into the insertion hole 33c of the third connection part 33 of the device main body 10, so the control part of the massage device 1 does not detect the connection of the stimulation attachment 70 (in other words, it considers the stimulation attachment 70 to be in a state where it is not connected), and selects and executes a vibration mode that imparts vibrations to the user's body.

[0061] This allows the control unit (particularly the motor control unit) of the massage device 1 to drive the motor 23 according to the conditions selected by the user with the operation button 41 of the operation unit 40. Therefore, the rotational motion of the motor 23 is converted into a reciprocating motion by the transmission unit 50 and transmitted to the connection unit 30, whereby the vibration attachment 80 connected to the connection unit 30 can impart vibration to the user's body. This allows the user to obtain effects such as relieving muscle stiffness and promoting blood circulation in the area where the vibration attachment 80 comes into contact with the body due to the vibration of the vibration attachment 80.

[0062] That is, according to the massage device 1 of this embodiment, by using one device main body 10 and at least two attachments 60, it is possible to perform two different operations (functions): imparting electrical stimulation with the stimulation attachment 70 and imparting vibration with the vibration attachment 80. Also, in this embodiment, the function of the massage device 1 can be easily changed by simply replacing the attachments 60 (the stimulation attachment 70 and the vibration attachment 80) connected to the connection part 30 of the device main body 10.

[0063] Therefore, the massage device 1 of this embodiment can broaden the range of options available to the user regarding how to use the massage device 1. Also, the user can easily select the function he or she wants to use at any given time from the different functions of the two attachments 70 and 80. Therefore, the massage device 1 of this embodiment can improve added value compared to conventional general massage devices.

[0064] In particular, in the massage device 1 of this embodiment, when the stimulation attachment 70 is connected to the connection part 30 of the device main body 10, the control part of the massage device 1 can stably detect that the stimulation attachment 70 is connected to the connection part 30 of the device main body 10, as described above. This allows the control part of the massage device 1 to smoothly execute the stimulation mode. Furthermore, in this case, the control part does not operate the motor 23, so that the stimulation attachment 70 can be reliably prevented from being reciprocated by the motor 23.

[0065] On the other hand, when the vibration attachment 80 is connected to the connection part 30 of the device main body 10, the control part of the massage device 1 does not detect that the stimulation attachment 70 is connected to the connection part 30. This allows the control part of the massage device 1 to smoothly execute the vibration mode and also reliably prevents power from being supplied to the vibration attachment 80.

[0066] Furthermore, in the massage device 1 of this embodiment, as described above, the control unit is configured to be able to select and execute either the stimulation mode or the vibration mode, so that with just one operation button 41 provided on the operation unit 40 of the device main body 10, it is possible to gradually change both the strength of the electrical stimulation of the stimulation attachment 70 in the stimulation mode and the vibration level of the vibration attachment 80 in the vibration mode.

[0067] That is, in the massage device 1 of this embodiment, the operation button 41 for the strength of the electrical stimulation and the operation button 41 for the vibration level can be integrated into one. This allows the massage device 1 to be formed in a simpler shape, which is expected to have the effect of improving the design of the massage device 1 and the appearance quality of the massage device 1. Furthermore, the number of parts that form the device main body 10 can be reduced, which can reduce manufacturing costs.

[0068] In the massage device 1 of this embodiment, the control unit of the massage device 1 is configured to select and execute one of two operation modes, a stimulation mode by the stimulation attachment 70 and a vibration mode by the vibration attachment 80. However, in the present invention, one or more attachments having different functions may be additionally prepared, and the control unit of the massage device may be configured to select and execute one of three or more operation modes.
