BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tapping massage machine that is applied to stiff shoulders and the like.

0002

[Prior Art] Conventionally, a tapping ball, which is a tapping member, is connected to a plunger of an electromagnetic solenoid, and each time a voltage is applied to the electromagnetic solenoid, that is, per one tapping operation,
By applying a pulse voltage of
The beating strength (pounding force) depends on the length of the voltage application time.
There were some that made it variable (for example, the
No. 822, JP-A-55-141241, JP-A-60-
No. 48747, Utility Model Application No. 51-2458).

That is, in this tapping massage machine, when the application time t1 of the applied voltage P1 shown by the solid line in FIG. 5 is short, the tapping force Q1 is weak as shown in FIG. When t2 is long, the striking force Q2 becomes strong as shown in FIG. Therefore, in order to obtain sufficient tapping force (feel in use), the voltage application time is lengthened to increase the rate of change of the tapping force over time and the tapping force (peak value).

[0004] Furthermore, by making the striking strength variable in conjunction with the striking speed, and weakening the striking strength as the striking speed increases, the same feeling of use can be provided even if the striking speed is changed. There was something (Tokuko Sho 55-2686
No. 2) is basically the same as above.

[0005]

[Problems to be Solved by the Invention] However, if the voltage application time is increased in order to obtain sufficient tapping force (feeling of use) in one tapping operation, the rate of change of the tapping force with respect to time becomes large, and the tapping force peaks. Since the value becomes too large, the user feels pain rather than a sufficient feeling of tapping, and this causes problems such as damage to tissues such as the muscles and skin of the area to be hit, and a reduction in the effectiveness of the tapping massage.

[0006] Accordingly, an object of the present invention is to provide a tapping massage machine that can give the user a sufficient tapping sensation without causing the user to feel pain with a single tapping operation.

[0007]

[Means for Solving the Problems] The tapping massage machine of the present invention includes an electromagnetic solenoid having a movable part formed by connecting a tapping member that contacts a part to be hit to a plunger, and a pulse voltage that drives the plunger to the electromagnetic solenoid. The device includes a drive means for supplying the solenoid, and a weight member provided on the movable portion so as to be interlocked with a delay in the operation of the movable portion.

[0008]

[Operation] According to the structure of the present invention, when the driving means is operated to apply a pulse voltage to the electromagnetic solenoid, the striking member, which attracts the plunger of the movable part, is driven for each pulse voltage and strikes the striking part. The striking member retreats each time the pulse voltage stops. Further, the weight member applies a striking force to the struck part with a slight delay from the previous striking force through the striking member operated by its inertia with a slight delay with each movement of the movable part. For this reason, it is possible to lengthen the application time of the striking force without increasing the peak value of the striking force too much in one striking operation. Therefore, compared to conventional methods, the rate of change of the hitting force over time and the peak value of the hitting force do not increase, so the user does not feel any pain, and the muscles and skin of the area being hit are not increased. A sufficient tapping feeling can be given to the user by one tapping action without damaging tissues, and the massage effect can be improved.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. 1 and 2. That is, this tapping massage machine includes an electromagnetic solenoid 1, a head cover 2 that covers the electromagnetic solenoid 1, a tapping member 3 that is a tapping ball attachment connected to the electromagnetic solenoid 1 near the head cover 2, the head cover 2 and the electromagnetic solenoid 1. It is composed of a connecting spring 4 that supports the handle 5, and a handle 5 that includes a driving means 28.

First, the electromagnetic solenoid 1 has an excitation coil 12 wound around the outer periphery of a cylindrical coil frame 11 and a yoke 13 outside the excitation coil 12 as main fixing members. A movable iron core 15 is housed in a movable iron core 15 for reciprocating movement, and a movable iron core 15 is coupled to one end of the movable iron core 15,
It consists of a drive rod 17 inserted through a through hole 16 in the center of the yoke 13.

An elastic body such as rubber is formed between the flange 18 protruding from the side of the rear end of the movable core 15 and the upper surface of the yoke 13 and absorbs the impact of the flange 18.
A sound insulating elastic body 19 through which 5 is inserted is interposed. A cylindrical iron core 2 fitted into the inner peripheral edge of the through hole 16 of the yoke 13
0 is stored in the lower part of the hole of the coil frame 11, and the iron core part 20
A guide bush 21 into which the drive rod 17 is inserted so as to be reciprocally movable is installed in the guide bush 21 to constitute a sliding portion of the plunger 14.

Further, two extending plate portions 22 that are vertically opposed to each other are integrally formed outwardly extending from the joint portion of the central portion of the yoke 13, and these two extending plate portions A connecting member 4, which will be described later, is sandwiched between the members 22. A striking member 3 is fixed to the tip of the driving rod 17 of the plunger 14 and can freely come into contact with a part to be beaten such as the shoulder or waist.
is configured. Further, the lower end of the yoke 13 has a soundproof elastic body 23 for absorbing the impact sound of the striking member 3, and a return spring body 24 for biasing the striking member 3 with a spring.

Furthermore, a storage member 32 is attached to the rear end of the plunger 14, and a weight member 3 is attached to the inside of the storage member 32 at a position facing the rear end of the movable iron core 15 via a push spring 31.
0 is attached, and the weight member 30 is pressed against the rear end portion of the movable iron core 15 by the push spring 31. Therefore, weight member 3
0 is interlocked with the movement of the movable part 34 with a delay due to its inertia. An elastic body 33 for absorbing the impact of the weight member 30 is attached to the rear end of the movable core 15 with adhesive or the like.

The connecting member 4 is a magnetic connecting member having a long and narrow plate shape and having a predetermined spring constant, and a connecting hole having the same positional relationship as the extending plate portion 22 of the electromagnetic solenoid 1 is bored at its tip. The leading end portion is interposed between the extending plate portions 22, and a rivet 25 is inserted into each connecting hole, and the two are connected and fixed by rivet connection. The handle part 5 has a power switch 26 and a power cord 27 installed therein, and a driving means 28 is housed therein, and the other end of the connecting member 4 is connected and fixed to the front part. The driving means 28 is connected to a commercial power source and intermittently supplies a pulse voltage to the electromagnetic solenoid 1 in order to perform a tapping operation every time a pulse voltage is applied.

The operation of this electromagnetic solenoid 1 will be explained first. That is, when the power cord 27 is connected to a commercial power supply, the handle part 5 is held in the hand, and the beating member 3 is brought into contact with the part to be beaten, such as the shoulder or waist, the plunger 14 will move as shown in FIG.
slides from the state shown by the solid line to the position shown by the imaginary line. Next, when the power switch 26 is turned on, a pulse voltage is applied to the excitation coil 12 of the electromagnetic solenoid 1, and a pulse current is supplied to the excitation coil 12. This causes the plunger 14, which has a small mass and small inertia, of the electromagnetic solenoid 1 to move into the iron core. The tapping member 3 protrudes outward from the electromagnetic solenoid 1, and the pushing force (pushing amount) to the hitting portion due to this operation is applied to the hitting portion as a tapping force, and a tapping operation is performed. Further, since a pulse voltage is applied to the excitation coil 12, after the pulse voltage ends, the plunger 14 is pushed back by the returning force (load) of the struck part, returning to the state before the pulse voltage was applied to the excitation coil 12. return. On the other hand, during the tapping operation, the fixed part of the electromagnetic solenoid 1, which has a large mass and large inertia relative to the plunger 14, moves up and down to some extent with respect to the part to be hit due to the reaction force of the tapping force. By applying a pulse voltage to the electromagnetic solenoid 1, the plunger 14 pushes the part to be struck via the striking member 3, thereby performing a series of striking operations.

[0016] Also, the delay-linked operation of the weight member 30 will be explained. That is, before a pulse voltage is applied to the excitation coil 12 of the electromagnetic solenoid 1, the plunger 14 of the electromagnetic solenoid 1 is in the state shown in FIG. 2(a) (imaginary line in FIG. 1). Next, when a pulse voltage is applied to the excitation coil 12 of the electromagnetic solenoid 1 and a pulse current is supplied to the excitation coil 12, the attraction operation of the plunger 14 by the electromagnetic solenoid 1 is performed as shown in (b) and (c) of FIG. The plunger 14, which has a small mass and is small in size, pushes the striking member 3, and this pushing force (pushing amount) is applied as a striking force to the striking part through the striking member 3, and a striking operation is performed. On the other hand, the weight member 30 interlocked with the plunger 14 moves away from the elastic body 33 on the upper side of the movable core 15 due to its inertia, as shown in FIGS. 2(b) and 2(c), and causes the push spring 31 to bend. As a result, the plunger 14 is pushed back in the opposite direction to reduce the peak value of the striking force, and then when the pulse voltage to the excitation coil 12 disappears and the plunger 14 starts to be pushed back by the returning force (load) of the struck part, Or, when being pushed back, as shown in FIG. 2(d), the weight member 30 is delayed and collides with the movable core 15 via the elastic body 33, and by pushing the plunger 14 again in the direction of the struck part, an additional striking force is generated. will be applied to the struck portion. In this way, the weight member 30 that is delayed and interlocked with the movable iron core 15 makes it possible to lengthen the application time of the striking force without increasing the peak value of the striking force during one striking operation. Therefore, as in the conventional example, 1
In order to perform the tapping action repeatedly, the rate of change of the hitting force over time and the peak value of the hitting force are simply increased, causing the user to feel pain or damaging tissues such as the muscles and skin of the area being hit. The massage effect can be improved because the user can be given a sufficient tapping feeling with one tapping motion like a masseuse without having to do much.

[0017] In addition, even in one of the masseuse's tapping techniques, the fist is not tightly clenched, but rather the palm and thumb are lightly clenched to make a difference in the amount of time the palm and thumb hit the area to be hit, and the hitting force is as shown in Figure 3. In this way, the peak value of the hitting force is not made too large, and the application time t3 of the hitting force is lengthened to provide sufficient hitting force (hitting feeling) Q3, Q4 to the part to be hit. It has come close.

A second embodiment of the invention is shown in FIG. That is, in this tapping massage machine, a hollow part 35 is provided in the tapping member 3, and a weight member 30, which is an example of a plurality of small iron balls, is housed in about half the space of the hollow part 35. This embodiment also has the same effect as the first embodiment because it is delayed and interlocked with the movement of the movable part 34 due to the inertia of the weight member 30. Moreover, according to this embodiment, since the weight member 30 is housed within the beating member 3, the size can be reduced.

Note that the push spring 31 of the first embodiment may be omitted. Further, in this embodiment, the present invention is a handy massage machine that is held in the hands of the user, but it may be applied to other large massage machines such as chairs and beds.

[0020]

[Effects of the Invention] The tapping massage machine of the present invention includes an electromagnetic solenoid having a movable part formed by connecting a tapping member that contacts a part to be hit to a plunger, and a pulse voltage that drives the plunger supplied to the electromagnetic solenoid. Since it includes a driving means and a weight member provided on the movable part so as to be interlocked with a delay in the operation of the movable part, each pulse voltage can be adjusted by operating the driving means and applying a pulse voltage to the electromagnetic solenoid. Each time the plunger of the movable part is attracted, the striking member is driven to strike the struck part, and with a slight delay after each movement of the movable part, the weight member moves to the struck part through the inertia of the striking member. Apply the striking force of the weight member a little later than the striking force. For this reason,
In one tapping operation, the application time of the tapping force can be increased without increasing the peak value of the tapping force too much. Therefore, compared to conventional methods, the rate of change of the hitting force over time and the peak value of the hitting force do not increase, so the user does not feel any pain, and the muscles and skin of the area being hit are not increased. This has the effect that it does not damage tissues, provides a sufficient tapping sensation to the user with a single tapping action, and improves the massage effect.
