Description

  The present invention relates to a body trimming device (acupuncture device) having a mechanism for applying not only a human pressing force of a user or the like but also an instantaneous force generated mechanically to an acupuncture point of an affected area.

  In particular, when the pressing part of the body trimming device is pressed against the affected part and used, the force action is such that it first moves backward while resisting the elastic force and returns to a predetermined state when it is retracted to a predetermined state. A member is provided, and an instantaneous force generated during the returning operation is applied to the affected part from the pushing part.

  In the present specification, the side of the pusher that acts on the affected part is described as “front” or “bottom” of the trimming instrument, and the opposite pressing operation side is “back” or “top” of the trimming instrument. .

  A conventional acupuncture point pushing device (manipulator for body treatment) of the affected part is of a type in which the pushing part is pressed against the affected part only by the force of the person who operates it.

In addition, if the pressing force at this time exceeds a predetermined pressure, the acupuncture point can be pushed with a constant pressing force by using a mechanism in which the pushing portion moves backward, that is, the acupoint pushing that prevents the pressing force from being applied more than necessary. Appliances have also been proposed (see Patent Document 1).
JP 2003-70875 A

  Such a conventional acupoint pushing device (manipulative device) presses the affected area only by the operator's force.

  Therefore, the pressing force against the affected part does not occur instantaneously, and the affected part is pressed in a relatively gradual (at least not instantaneous) time, so there is room for improvement in terms of the effectiveness of the acupoint pressing. It was.

  The present invention applies an instantaneous force (instantaneous wave) based on a mechanical operation to the affected part in a stage where the predetermined pressed state is applied, in addition to pressing the affected part with the operator's power, thereby The purpose is to increase the efficacy of the device (acupuncture device) on the affected area.

When the transition from the initial state where the opposed position to the rear end portion of the shaft portion in the movement is shifted from the concave portion to the instantaneous force generation state that matches the concave portion, the first elasticity A force acting member (for example, an instantaneous force generating member 24 to be described later) that returns to the front in a form in which the concave portion is guided to the shaft portion by the action of force;
A first elastic member that exhibits the first elastic force (for example, a spring spring 8 described later);
A central hole portion through which the shaft portion passes, and a part of the annular front surface portion around the concave portion of the force acting member abut on the outer edge side from the central portion side where the central hole portion is formed.

The force acting member is
In the initial state,
The annular front surface portion of the force acting member front side portion including the annular rear surface portion and the annular front surface portion around the concave portion is pressed by the central portion side portion of the slope-shaped surface region where the upward slope is formed; and When the annular front surface portion comes into contact with the large-diameter inner peripheral surface,

By moving to
The displacement between the longitudinal direction of the force acting member and the longitudinal direction of the shaft portion is eliminated, and the concave portion of the force acting member and the rear end portion of the shaft portion face each other and move to a position where they match. The structure to be taken is taken.

The feature of the body trimming instrument of the present invention is that the front barrel 3 and the like are relatively advanced toward the affected part in a state where the pushing part 1 is applied to the affected part.
(1) The rear end side of the instantaneous force transmitting member 4 and the front end of the instantaneous force generating member 24 which are displaced from the central axis in the front-rear direction of the entire body trimming instrument (hereinafter simply referred to as “instrument central axis” as necessary). And the instantaneous force generating members 7 and 24 are retracted against the elastic force of the steel spring 8 (see FIGS. 1 (b) and 2 (b)),
(2) When the longitudinal direction of the instantaneous force transmitting member 4 or the instantaneous force generating member 24 substantially coincides with the instrument central axis, that is, the small diameter portion 4e of the instantaneous force transmitting member or the rear end surface of the shaft portion 21 is the instantaneous force generating member. When opposed to the concave portions 7a, 24a of 7, 24, the instantaneous force generating members advance at a stretch by the elastic force of the spring springs 8, respectively, and the rear end surfaces of the instantaneous force transmitting member 4 (small diameter portion 4e) and the shaft portion 21. [See Fig. 1 (c), Fig. 2 (c)],
(3) The instantaneous wave accompanying this collision is applied to the affected part via the push part 1,
This is what I did.

  Thereby, the instantaneous wave based on the operation of the internal mechanism of the body trimming tool, not the force of the user of the body trimming tool, is reliably applied to the affected part with a predetermined strength, and the body trimming effect can be enhanced.

  In the case of the instantaneous force generating mechanism shown in FIG. 1 (a), the shaft 2 and the instantaneous force transmitting member 4 are each urged forward by the action of the spring spring 5, and the instantaneous force transmitting member 4 has a central axis in the front-rear direction. The rear end side is biased so as to deviate from the instrument center axis as shown in the figure.

  Due to this urging force, the shaft portion 2 transitions to a state where the head 2a abuts against the inner bottom surface portion (portion following the hole portion) of the front shaft cylinder 3, and the instantaneous force transmission member 4 has a small diameter portion 4e whose center diameter tube 4 6 is brought into contact with the cylindrical inner peripheral surface 6b.

  Further, the instantaneous force generating member 7 is urged forward by the action of the spring spring 8, and the annular tapered bottom surface 7 b transitions to a state in which it abuts on the rear tapered surface 6 c of the middle barrel 6.

  The shape of the spring spring 5 is such that when the front end portion of the spring spring 5 is placed on a horizontal plane, the whole is inclined (not upright), and when assembled, the front end portion is fitted to the large diameter portion 4c of the spring receiving shaft 4b. The shape is such that

  With this shape, the instantaneous force transmission member 4 is urged to abut against the inner peripheral surface 6b as described above. In addition, the spring bearing shaft 4b of the instantaneous force transmission member 4 shown in the figure is in a form standing upright on the seat portion 4a.

  The spring receiving shaft 4b is inclined with respect to the seat portion 4a (not upright as shown), and the steel spring 5 is in a normal coil spring shape (ie, a shape that is upright when placed on a horizontal surface). By doing so, the small diameter portion 4e may come into contact with the cylindrical inner peripheral surface 6b of the middle shaft cylinder 6.

Here, when the front barrel 3, the middle barrel 6, the tail plug 9, the top cover 10, and the like (hereinafter referred to as “housing”) are further pushed in with the pushing portion 1 applied to the affected area, FIG. 1. As shown in (b) and FIG.
(21) The instantaneous force transmission member 4 is relatively retracted in the housing against the elastic force of the spring spring 5, and the instantaneous force generation member 7 also has an annular tapered bottom surface 7b at the small diameter portion 4e of the instantaneous force transmission member. Retreats against the elastic force of the spring spring 8 by being pushed,
(22) In the instantaneous force transmission member 4, the taper portion 4d is guided to the front taper surface 6a of the central shaft cylinder 6 with this retreat, so that the rear end of the small diameter portion 4e becomes the concave portion 7a of the instantaneous force generation member 7. As you approach, you get up,
(23) Then, when the rear end of the small diameter portion is opposed to the concave portion 7a of the instantaneous force generating member 7, that is, when the central axis in the front-rear direction of the instantaneous force transmitting member 4 is moved to a position substantially coincident with the instrument central axis, The instantaneous force generating member 7 that has been retracted until then moves instantaneously forward based on the elastic force of the steel spring 8 such that the concave portion 7 a is guided by the small diameter portion 4 e of the instantaneous force transmitting member 4.

  By this movement, the instantaneous force generating member 7 collides with the small diameter portion 4e of the instantaneous force transmitting member 4, and the instantaneous force generated at that time is applied to the affected part in the form of an instantaneous wave via the shaft portion 2 and the push portion 1. . Since the instantaneous wave applied to the affected part penetrates the human body for a long time, the therapeutic effect can be improved.

  When the trimming instrument after application of the instantaneous force described above, that is, the trimming instrument in the state of FIG. 1C, is separated from the affected part, the shaft part 2 and the instantaneous force transmission member 4 of FIG. Return to the initial state.

The basic difference between the instantaneous force generation mechanism of FIG. 2 and that of FIG. 1 is that in the stationary mode of FIG.
-The longitudinal force central axis of the instantaneous force transmission member (shaft portion 21) is aligned with the instrument central axis, and the longitudinal central axis (direction) of the instantaneous force generation member 24 is shifted from the instrument central axis.
A position control ring 23 is provided as a member for shifting the center axis in the front-rear direction of the instantaneous force generation member 24.
That is.

  That is, in the case of the instantaneous force generation mechanism shown in FIG. 2A, the shaft portion 21 and the instantaneous force generation member 24 are urged forward by the action of the springs 25 and 8 respectively. Further, the position control ring 23 and the instantaneous force generating member 24 are urged toward each other by the action of these peeling springs.

  The instantaneous force generation member 24 is biased by the spring spring 8 and the annular tapered bottom surface 24b abuts against the slope-shaped top surface 23a of the position control ring 23 so that the radial direction (= direction orthogonal to the instrument central axis). ) And is initially set in such a manner that its center axis in the front-rear direction is deviated from the instrument center axis as shown in the figure.

  In the stationary mode in which the elastic force pushing portion 1 is not pressed against the affected part or the like, the shaft portion 21 and the instantaneous force generating member 24 do not come into contact with each other, and the instantaneous force generating member is stable at a lower position on the slope-shaped top surface 23a. is doing.

  Note that the instantaneous force generating member 24 may be tilted as shown in the figure by omitting the position control ring 23 and using a member having the same oblique property as the steel spring 5 of FIG. 1 instead of the steel spring 8. . In this case, for example, a spring spring is fixed to the instantaneous force generating member 24.

Here, when the casing is further pushed in with the pushing part 1 applied to the affected part, as shown in FIGS. 2 (b) and 2 (c),
(31) First, the shaft portion 21 is relatively retracted against the elastic force of the spring spring 25, and the rear end surface of the shaft portion 21 is brought into contact with the annular tapered bottom surface 24b of the instantaneous force generating member 24.
(32) The shaft portion 21, the position control ring 23, and the instantaneous force generating member 24, which are integrated as a result of this contact, are relatively retracted against the elastic force of the spring spring 8, and the instantaneous force transmitting member 24 With this retreat, the annular taper rear surface 24c is guided to the taper inner peripheral surface 22a of the middle shaft cylinder 22, so that the concave portion 24a rises so as to approach the rear end surface of the shaft portion 21,
(33) When the rear end surface and the concave portion 24 are opposed to each other, that is, when the center axis in the front-rear direction of the instantaneous force generating member 24 is moved to a position substantially coincident with the instrument central axis, The force generating member 24 and the position control ring 23 are instantaneously moved forward based on the elastic force of the steel spring 8 in such a manner that the concave portion 24 a of the member is guided by the shaft portion 21.

  Due to this movement, the instantaneous force generating member 24 collides with the rear end surface of the shaft portion 21, and the instantaneous force generated at that time is applied to the affected part through the push portion 1 in the form of an instantaneous wave.

  When the trimming instrument after applying the instantaneous force, that is, the trimming instrument in the state shown in FIG. 2C, is separated from the affected area, the shaft portion 21 moves forward by the action of the spring spring 25, and the action of the spring springs 25, 8 is inherent. The instantaneous force generating member 24 that is in contact with the position control ring 23 rotates in the downward direction of the drawing while following the slope-like top surface 23a of the ring, and returns to the initial state of FIG. .

  At the stage where the forward movement of the shaft portion 21 is finished, the rear end surface thereof is separated from the annular tapered bottom surface 24b of the instantaneous force generating member 24. Therefore, the instantaneous force generating member is also rotated downward in the drawing. Performed smoothly.

  As shown in FIG. 3 (b), it is also possible to use in a state where the screw connection between the middle shaft cylinders 6, 22 and the tail plug portion 9 is stopped halfway. Thereby, the full length of the trimming instrument in use can be changed, and the magnitude of the instantaneous force can be adjusted.

  The trimming instrument of FIG. 4 uses a tail plug portion 31 with a handle portion 31a. That is, the top cover portion 10 in the case of FIGS. 1 to 3 is omitted. As a result, for example, the handle 31a is firmly pressed with the entire thumb or the like by holding the outer peripheral surface of the trimming instrument, or the handle 31a is hung on a hook or the like when the trimming instrument is not in use. can do.
