Detailed Description

Hereinafter, embodiments will be described with reference to the drawings.

As shown in fig. 1, the facial muscle exerciser 21 of the present embodiment is held by the lips of the user, and the user shakes the facial muscle exerciser 21 up and down to exercise the facial muscles such as the orbicularis oris muscle of the user and the buccinator muscle and the laughing muscle connected to the orbicularis oris muscle.

As shown in fig. 3, 4, and 8, the facial muscle exerciser 21 includes a linear band plate-shaped elastic plate 22 formed of a plate spring made of a steel plate. As shown in fig. 9 and 11, a core 27 made of a hard resin such as polypropylene is fixed to the center portion of the elastic plate 22 in the longitudinal direction by insert molding using the elastic plate 22 as an insert. The core 27 is formed with a protruding portion 272 protruding from one end edge of the elastic plate 22. A mouthpiece 28 formed in a hollow shape is detachably attached to the protruding portion 272 of the core 27, and a holding portion 24 held by the lips is formed by the mouthpiece 28 in the attached state.

As shown in fig. 3, 6, and 8, the entire elastic plate 22 and the core 27 except for the projection 272 are molded with the coating layer 23, and the coating layer 23 is formed of a synthetic resin such as urethane. The coating layer 23 is made of a synthetic resin softer than the core 27. A pair of through holes 222 are formed in both end portions of the elastic plate 22. The inner through-hole 222 serves to allow the synthetic resin to enter when the coating layer 23 is formed and to reinforce the combination of the elastic plate 22 and the coating layer 23. As shown in fig. 5 and 6, the bush 26 is forcibly fitted into the outer through hole 222 and protrudes from both front and back surfaces of the elastic plate 22. However, the bush 26 has a height not exposed from the surface of the coating layer 23. Small holes 224 are formed at both ends of the elastic plate 22. The small hole 224 also serves to allow the entry of synthetic resin and reinforce the elastic plate 22 and the coating layer 23 in combination.

The elastic plates 22 and the coating 23 on the left and right sides of the core 27 form a pair of left and right arms 31. The weighted portions 25 are provided at the distal end portions of the coating layers 23 on the arms 31, respectively.

As shown in fig. 1, by holding the holding portion 24 with the lips and shaking the whole of the facial muscle exerciser 21 up and down, the both arms 31 are vibrated up and down by the load of the weight portion 25, the elasticity of the elastic plate 22, and the like, resonating with the shaking. Here, resonance means: when vibration of the number of vibrations within a predetermined range is applied to the holding portion 24, the arm 31 largely vibrates. It is particularly preferable that the end of the arm 31 is bent to a position higher than the height of the holding portion 24. Thereby, the load acts on the facial muscles of the user holding the holding portion 24, thereby exercising the facial muscles.

As shown in fig. 9 to 13, a concave-convex portion 271 for locking and holding the mouthpiece 28 is formed on the outer peripheral surface of the core 27. The mouthpiece 28 is formed of a soft synthetic resin such as polyurethane which is softer than the core 27 and is less likely to slip. An uneven portion 281 engageable with the uneven portion 271 of the core 27 is formed on the inner peripheral surface of the mouthpiece 28. A recessed portion 282 is formed at the upper and lower portions of the central portion of the outer peripheral surface of the mouthpiece 28 so as to be held by the lips. As shown in fig. 13, the outer peripheral surface of the mouthpiece 28 at the portion of the recessed portion 282 is formed in an elliptical shape having a major diameter extending in the left-right direction. Therefore, since the curvature at 2 positions above and below the recessed portion 282 is smaller than the curvature at 2 positions on the left and right sides and is flat, the mouthpiece 28 is easily held. A recess 283 is formed on the outer peripheral surface of the distal end portion of the mouthpiece 28. A spherical convex portion 284 is formed on the outer peripheral surface of the distal end surface of the mouthpiece 28.

A pair of edge portions 285 are formed on the base end of the mouthpiece 28 on both front and back sides of the arm 31. The edge portion 285 protrudes from the other part of the mouthpiece 28, and as shown in fig. 9, when the facial muscle exerciser 21 is placed on an installation surface 100 such as the upper surface of a table, the edge portion 285 contacts the installation surface 100, and the mouthpiece 28 is inclined upward. Therefore, the portion of the mouthpiece 28 held by the lips can be prevented from contacting the setting surface 100, and can be kept clean.

By preparing a plurality of kinds of mouthpiece 28 having different outer dimensions and the like, the user can select an appropriate mouthpiece 28 according to the size, shape and the like of the mouth, and fit the mouthpiece to the outside of the core 27. The mouthpiece 28 is softer than the core 27, and has a hardness of, for example, 60 degrees on a durometer based on type a in accordance with JISK 6253.

As shown in fig. 5 and 14, holding holes 29 are formed at both end positions of the coating layer 23. The two weighted portions 25 are constituted by weights 30 detachably mounted in the holding holes 29. A plurality of weights 30 of different weights are prepared so that a weight 30 of an arbitrary weight is selected according to the degree of exercise or the like required by the user, and is detachably mounted in the holding hole 29.

A cover 51 is attached to the facial muscle exerciser 21 of this embodiment, and the cover 51 constitutes a set of facial muscle exerciser together with the facial muscle exerciser 21.

As shown in fig. 2 and fig. 15 to 17, the cover 51 is made of transparent or translucent synthetic resin such as polypropylene, polyethylene, or polyamide resin, and a pair of cover plates 53 and 54, which are halved, are provided by an integral hinge 52 at the center. The cover plates 53 and 54 are configured as a main body on one side and a cover on the other side, but in the present embodiment, the cover plate 53 on the lower side in fig. 15 is configured as a main body and the cover plate 54 on the upper side is configured as a cover. The 2 cover plates 53 and 54 are each formed in a concave shape, and a housing space 511 is formed therebetween. The holding portion 24 of the facial muscle exerciser 21 and the central portion of the coating layer 23 are housed in the housing space 511, and the portions are covered with the cover 51. A locking claw 55 is formed on one cover plate 53, a receiving portion 56 for engaging the locking claw 55 is formed on the other cover plate 54, and when the cover plates 53, 54 are closed, the cover 51 is held in a locked state by the engagement of the locking claw 55 and the receiving portion 56. A recess 58 is formed on the side wall of the 2 cover plates 53, 54. When the two cover plates 53, 54 are locked, the two recesses 58 form an opening 59 for passing the arm 31 while avoiding interference with the arm 31, and a gap 60 is formed between an edge of the opening 59 and an outer peripheral surface of the arm 31. The edge portion is formed in an arc-shaped cross section so that the opening 59 does not form a boundary, or is formed thick so that the contact area with the arm 31 is increased, or is formed thick and has an arc-shaped cross section, thereby preventing scratches and marks from being left on the arm 31.

Hereinafter, a method of using the facial muscle exerciser 21 configured as described above will be described.

As shown in fig. 2, when the facial muscle exerciser 21 is not in use, a cover 51 is attached to the central portion of the facial muscle exerciser 21 so as to cover the holding portion 24. Therefore, the lip-held portion can be kept clean. Since the cover 51 has a shape substantially along the outer surface of the mouthpiece 28, the facial muscle exerciser 21 in the attached state of the cover 51 can be housed in a dedicated case and can be carried and kept.

When the facial muscles are exercised by the facial muscle exerciser 21, the cover 51 is detached. In addition, according to the exercise degree required by the user of the facial muscle exerciser 21, a mouthpiece 28 having a desired outer size is previously mounted on the core 27, and a weight 30 of a desired weight is mounted in the holding hole 29 of the 2 weight parts 25. In this state, the face is swung up and down with the recessed portion 282 of the holding portion 24 being held in the lips. In this way, in a state where the weight of the facial muscle exerciser 21 is applied to the lips, the 2 weight parts 25 resonate vertically via the elastic plate 22 formed of a plate spring, and the vibration is transmitted to the holding part 24. Thereby, a load is applied to the facial muscles through the lips, thereby exercising the facial muscles.

In this case, the engagement portion 24 projects from the side edge of the arm 31 and is disposed at a position displaced outward from the side edge. Therefore, the facial muscle exerciser 21 is held by the lips in a one-armed state, and the load on the lips is increased. Therefore, the load based on resonance effectively acts as a load to the facial muscles, so that the facial muscles can be effectively exercised. At this time, since the recess 282 is formed in a laterally long elliptical cross section, the mouthpiece 28 can be held in a state where the lips are opened. By holding the mouthpiece 28 in a state where the lips are opened, the load due to resonance can be transmitted to the entire orbicularis oris muscle. Since the orbicularis oris muscle is connected to an expression muscle such as laughing muscle, the laughing muscle can be exercised by the orbicularis oris muscle, and effective exercise can be performed.

In the facial muscle exerciser 21 of this embodiment, the elastic plate 22 is molded in the coating layer 23 of synthetic resin, so that when the arm 31 is bent and resonates, movements other than the vertical vibration of the arm 31 intended for exercise, for example, twisting and micro-vibration of the elastic plate 22 can be suppressed. Therefore, it is possible to reduce the transmission of the obstructive motion to the lips of the user, and to use the facial muscle exerciser 21 comfortably. Instead of molding the entire elastic plate 22, a plate or sheet of synthetic resin may be fixed to both the front and back surfaces or to one of the front and back surfaces by bonding or the like.

The mouthpiece 28 is made of rubber having a moderate hardness and not easily slipping. Therefore, it is easy to hold and can transmit the load generated by the vibration of the arm 31 to the lips. If the mouthpiece 28 is too hard, the mouthpiece 28 will not fit into the lips and will not be easily held. In contrast, if the mouthpiece 28 is too soft, since it is difficult to maintain the facial muscle exerciser 21 in a stable state even if it can be held, and the vibration of the arm 31 is absorbed, the load for exercise is reduced.

When different users use the facial muscle exerciser 21, the mouthpiece 28 having different outer dimensions is detachably attached to the core 27, so that even users having different sizes and shapes of the mouth can use 1 of the facial muscle exerciser 21 in common.

The facial muscle exerciser 21 can change the weight 30 in the holding hole 29 of the weight unit 25 to another weight 30 having a different weight depending on the strength of the facial muscle and the degree of exercise.

After the exercise is completed, the mouthpiece 28 may be detached from the core 27 and may be washed as necessary, and the washed mouthpiece 28 is reattached to the mouthpiece 28. Therefore, the mouthpiece 28 can be kept clean and very hygienic. Thereafter, the cover 51 is mounted to the facial muscle exerciser 21 in such a manner as to cover the mouthpiece 28.

As described above, by covering the mouthpiece 28 with the cover 51, the mouthpiece 28 can be maintained in a clean state when the facial muscle exerciser 21 is carried or stored. In addition, by housing the separate mouthpiece 28 detached from the core 27, the mouthpiece 28 can be kept in a clean state when the mouthpiece 28 is carried or stored.

Hereinafter, a method of manufacturing the facial muscle exerciser 21 according to the present embodiment will be described.

First, the core 27 having the elastic plate 22 as an insert is injection molded at the center portion of the elastic plate 22 shown in fig. 7.

Next, the bush 26 is forcibly fitted into the pair of through holes 222 on both end sides of the elastic plate 22. Thus, the bush 26 is protruded on both front and back surfaces of the elastic plate 22.

Thereafter, as shown in fig. 6, the elastic plate 22 is set in the mold 101, and the synthetic resin to be the coating layer 23 is injected into the mold 101. In this case, the injection pressure of the synthetic resin at the initial stage of injection does not act on the elastic plate 22 uniformly, and the pressure acts on the elastic plate 22 periodically and non-uniformly. Therefore, there is a case where the elastic plate 22 is bent, and scratches or the like due to the edge of the edge or the like are formed on the molding surface of the die 102 of the molding die 101. However, in the present embodiment, when the elastic plate 22 is already bent, the elastic plate 22 can be brought into contact with the molding surface of the die while avoiding the bush 26 from coming into contact with the molding surface of the die.

Therefore, the formation of a scratch on the molding surface of the die 102 can be prevented. In a state where the filling of the synthetic resin into the die cavity 102 is completed, since the injection pressure is uniformly applied to the entire elastic plate 22, the elastic plate 22 is restored to its original shape by the bending thereof, and the elastic plate 22 linearly extends in the die cavity 102. Thus, after the forming is completed, the elastic plate 22 is cast into a fixed position within the formed coating layer 23.

However, in the facial muscle exerciser 21 of the present embodiment, when the holding portion 24 is held by the lips and shaken up and down, the arms 31 on both sides are bent and resonate. In this case, in the present embodiment, the length of the arm 31, the weight of the weight portion 25, and the elastic coefficient of the arm 31 including the elastic plate 22 are set so that the engagement portion 24 resonates with the arm 31 when vibrating at a vibration frequency of less than 6.50 hertz (Hz). Therefore, the user can hold and resonate the arm 31 with the lips, and can exercise effectively with the load. On the other hand, in the case where the number of vibrations exceeding 6.50Hz, that is, the engagement portion 24 reciprocates at short intervals, the arm 31 does not resonate, and therefore, the same state as the state where the rigid body which is not bent vibrates is obtained, and the load due to the resonance of the arm 31 is not transmitted to the lips, and thus, an effective exercise effect cannot be obtained.

In the facial muscle exerciser 21 of the present embodiment, the downward deflection of the arm 31 in the resting state, i.e., the downward deflection a of the tip end of the arm 31 with respect to the length b of the arm 31 shown in fig. 17, is set to exceed 4.8 percent (%). Therefore, when the holding portion 24 is vibrated up and down, the arm 31 is appropriately bent and vibrated. Therefore, the user can obtain an effective exercise effect. On the other hand, when the deflection is 4.8% or less, that is, when the arm has high rigidity and is not easily bent, resonance is not easily generated, and thus it is difficult to obtain an effective exercise effect.

In the facial muscle exerciser 21 of the present embodiment, the load applied to the holding portion 24 when resonance acts on the arms 31 is set to be less than 7.4 newtons (N). Therefore, when the arm 31 resonates by swinging the holding portion 24 up and down, an appropriate load acts on the user, and an effective exercise effect can be obtained. On the other hand, if the load is 7.4N or more, the load is too high, and it becomes difficult to rock the arm 31.

Hereinafter, the results of verifying the operation of the facial muscle exerciser 21 according to the embodiment will be described based on tables 1 to 6. In this verification, various kinds of elastic plates 22 shown in fig. 20(a) and described later are used. A projection 223 is formed at a middle portion in the longitudinal direction of the elastic plate 22. A variety of weight parts (not shown) to be described later are detachably attached to both ends of the elastic plate 22 by bolts, pins, or the like.

In table 1, 3 kinds of elastic plates 22 having a thickness of 0.6 millimeters (mm), 0.8mm, 1.0mm, and 7 kinds of elastic plates 22 having a length of 300mm, 400mm, 500mm, 600mm, 700mm, 800mm, 1000mm were prepared, and thus 21 kinds of elastic plates 22 were prepared in total. Then, 5 kinds of weight-added parts having weights of 6.0 milligrams (g), 11.5g, 23.5g, 48.0g, and 92.0g were prepared and attached to both ends of the 21 kinds of elastic plates 22, respectively, to prepare 105 kinds of samples 120 (see fig. 20 (b)). As shown in fig. 20(b), the projecting portion 223 of the elastic plate 22 was held by a pine type vibration tester 103 manufactured by itai sperm machine corporation, and various vibrations having an amplitude of 20mm in the vertical direction were applied to the sample 120, and the number of vibrations applied per second when the elastic plate 22 generates the maximum amplitude on the left and right sides was shown in table 1. The value of the number of vibrations to be applied when resonance occurs is determined based on the display of the display unit of the controller 105 of the vibration testing machine 103. The presence or absence of resonance is determined by visual inspection. Then, the above-mentioned various samples 120 were detached from the vibration testing machine 103, the mouthpiece 41 having the same size and hardness as those of the holding portion 24 was attached to the protrusion 223 of the elastic portion 22, and a body feeling test was performed on the sample 120 by 10 subjects, and the results were ranked in 4 ranks as shown in table 2. The 4 levels are arranged according to the result that 6 or more subjects feel resonance, that is, resonance is not generated (level 4), resonance is not generated easily (level 3), resonance is generated easily (level 2), and resonance is generated easily (level 1). The phrase "not to resonate" means that the arm 31 cannot resonate, and the phrase "not to resonate easily" means that the resonance is required to be known although the vibration is sensed. In addition, "-" in table 1 indicates that the number of vibrations could not be measured by the controller 105 of the vibration tester 103. Therefore, even if the number of vibrations per second is 1.17 or less, it can be confirmed that there is the elastic plate 22 in which the arm of the elastic plate 22 resonates.

(Table 1)

Resonance frequency (Hz)

(Table 2)

The resonance frequency (Hz) is easy to generate resonance level

As is apparent from tables 1 and 2, in the case of using the sample 120 in which the arm of the elastic plate 22 can resonate when the mouthpiece 41 is vibrated at a vibration frequency of less than 6.50 hertz (Hz), the arm can resonate, although the user does not easily resonate, and thus the present invention can be used for exercising the facial muscles. In the case of using the sample 120 in which the arm of the elastic plate 22 can resonate when the mouthpiece 41 is vibrated at a vibration frequency of less than 5.00Hz, the user is preferable because the arm is likely to resonate. In particular, in the case of using the sample 120 in which the arm can resonate when the mouthpiece 41 is vibrated at a vibration frequency of less than 3.50Hz, it is preferable because the user can more easily resonate the arm.

In the above-described conditions, in the case of using the sample 120 in which the arm can resonate when the mouthpiece 41 is vibrated at a vibration frequency exceeding 4.67Hz, the arm is not easily resonated by the user, but can resonate, and therefore, the sample can be used for exercising the facial muscles. In the case of the sample 120 in which the arm can resonate when vibrated at a vibration frequency exceeding 4.33Hz using the mouthpiece 41, the user can easily vibrate the arm, and therefore, the sample can be used for exercising the facial muscles. In particular, in the case of using the sample 120 in which the arm is resonated by the mouthpiece 41 at a vibration frequency of 1.17Hz or more, the arm is likely to resonate, which is preferable.

Even if the number of vibrations is less than 1.17Hz, resonance may occur, but the number of times the arm vibrates per second is reduced, which is not preferable because the exercise effect is reduced. Although resonance is less likely to occur when using the sample 120 in which the arm can resonate at a frequency of 6.33Hz or less using the mouthpiece 41, the user can resonate the arm and thus can exercise facial muscles. The sample 120 is preferably a sample in which the arm resonates when the mouthpiece 41 vibrates at a frequency of 4.67Hz to 3.50 Hz. In the sample 120, it is particularly preferable that the mouthpiece 41 vibrate at a frequency of 3.33Hz to 1.17Hz to cause the arm to resonate. In the sample 120, it is preferable that the mouthpiece 41 vibrate at a frequency of 1.17Hz to 3.40Hz to cause the arm to resonate. The sample 120 may be a sample in which the arm resonates when the mouthpiece 41 vibrates at a frequency of 1.17Hz to 4.80 Hz. Even in the sample 120 in which the arm resonates when vibrated at a frequency of 1.17Hz to 6.40Hz using the mouthpiece 41, exercise can be performed.

From another point of view, the sample 120 that can resonate the arm when the mouthpiece 41 vibrates at a vibration frequency in the range of 6.33Hz to 1.17Hz can be used for exercise, and the arm can resonate when the holding portion 24 vibrates at a vibration frequency in the range of 6.33Hz to 5.0 Hz. It is also preferable that the sample 120 be capable of resonating the arm when the mouthpiece 41 is vibrated at a frequency in the range of 6.33Hz to 3.50 Hz. More preferably, the sample 120 is one in which the arm can resonate when the mouthpiece 41 is vibrated at a frequency in the range of 4.67Hz to 1.17 Hz.

Table 3 shows 90 kinds of samples 120 prepared by combining 3 kinds of elastic plates 22 having a thickness of 0.6mm, 0.8mm and 1.0mm, and 6 kinds of total 18 kinds of elastic plates 22 having a length of 400mm, 500mm, 600mm, 700mm, 800mm and 1000mm, and 5 kinds of weight-added parts having a weight of 6.0g, 11.5g, 23.5g, 48.0g and 92.0 g. As shown in fig. 18, the deflection amount a of the left and right arms of the elastic plate 22 in the natural state was measured in mm units, and the ratio of the value to the length b of the arm of the elastic plate 22, that is, the deflection amount was shown in table 3. These various samples 120 were subjected to a somatosensory experiment by 10 subjects in the same manner as described above, and the results were ranked in 4 ranks in table 4 in the same manner as described above in table 2.

(Table 4)

Natural state deflection easily produces resonance grade

Therefore, in the sample 120 in which the deflection of the arm in the stationary state exceeds 4.8%, the user can cause the arm to resonate. In the case of the sample 120 having a deflection exceeding 8.1%, the arm is likely to resonate, which is preferable. When the deflection exceeds 15.0%, the arm is particularly likely to resonate, which is preferable. Although resonance is not easily generated at a deflection of less than 8.3%, it can be made to resonate. When the deflection is less than 15.2%, resonance tends to occur, and therefore, this is preferable. When the deflection is less than 60.8%, resonance is particularly likely to occur, and therefore, this is more preferable.

From other points of view, resonance can occur when the deflection is in the range of 5.0% to 60.8%. Specifically, it was shown that resonance could be generated when the deflection was in the range of 5.0% to 8.1%, resonance could be easily generated when the deflection was in the range of 8.3% to 60.8%, resonance could be easily generated when the deflection was in the range of 8.3% to 15.0% and in the range of 48.8% to 60.8%, and resonance was especially easily generated when the deflection was in the range of 15.2% to 48.8%. As described above, although resonance is likely to occur when the deflection is 60.8%, if the deflection is far beyond 60.8%, it is estimated that the motion of the mouthpiece 41 is not easily transmitted to the elastic plate 22 and the arm is not likely to resonate. The arm is easily resonated even when the deflection is in the range of 15.1% -60%. Resonance is liable to occur even when the deflection is in the range of 8.2% -60.0%. Resonance can be generated even when the deflection is in the range of 4.9% -60.0%.

In Table 5, as described above, based on 3 kinds of elastic plates 22 having a thickness of 0.6mm, 0.8mm and 1.0mm and 6 kinds of total 18 kinds of elastic plates 22 having a length of 400mm, 500mm, 600mm, 700mm, 800mm and 1000mm, and 5 kinds of weight-added parts having a weight of 6.0g, 11.5g, 23.5g, 48.0g and 92.0g were combined to prepare 90 kinds of samples 120. As shown in fig. 20(b), the protruding portion 223 of the elastic plate 22 is sandwiched from above and below by the vibration tester 103, and the elastic plate 22 is vibrated up and down by the vibration tester 103 under the same conditions as those in table 1. At this time, the maximum load acting on the sample 120 is detected by the deflection sensor 104, and the detected data is analyzed by the controller 105 and displayed in newton (N) units. Model number of Strain gauge TYPE as a flexure sensor manufactured by tokyo institute of measuring instruments ltd: FLA-5-11-3L was used. Incidentally, the load acting on the sample 120 is affected by the load of the elastic plate 22 and the weight portion, the repulsive force of the elastic plate 22, and the acceleration applied by the vibration. The controller 105 sets the output of the deflection sensor 104 in the stationary state to zero as a reference value, and measures the load applied to the protrusion 223 of the elastic plate 22 from the deflection amount. The amount of action of the gravity applied to the elastic plate 22 was added, and the maximum value of the load calculated in this manner was included in table 5. Each sample 120 was subjected to a somatosensory experiment by 10 subjects in the same manner as described above, and the results were ranked as: the resonance cannot be generated (level 3), but the resonance is not easily generated but can be generated (level 2), and 3 levels of the resonance (level 1) are easily generated. Table 6 shows the rank.

(Table 5)

Load (N)

(Table 6)

Easy load swing rating (N)

As a result, the user can resonate the arm in the sample 120 in which the arm resonates with a load of less than 7.4N, and particularly, the user easily resonates the arm in the sample 120 in which the arm resonates with a load of less than 3.9N. In the case of the sample 120 in which the arm resonates with a load of less than 1.5N, although it is assumed that the arm easily resonates, the verification is not performed because the capability of the detector is exceeded.

From another point of view, in the case of the sample 120 in which the arm resonates within a range of 3.9N to 7.1N with the load applied to the mouthpiece 41, the user can resonate the arm, and in the case of the sample 120 in which the arm resonates within a range of 1.5N to 3.8N with the load, the user is particularly likely to resonate the arm. The user can vibrate the arm even when the arm resonates with a load in the range of 1.5N-3.85N. When the load is less than 1.5N, the arm can resonate, but the load amount is small and the exercise effect is small.

Therefore, if various conditions such as the length of the arm 31 of the facial muscle exerciser 21, the weight of the weight 30, and the like are set arbitrarily, the facial muscle exerciser 21 showing various behaviors which are counted in tables 1 to 6 will be embodied. Such a facial muscle exerciser 21 can obtain the same effect as the verification result.

However, the effect of 67 men and women aged 20 to 70 was verified by using the facial muscle exerciser 21 of the present embodiment continuously for 8 weeks 2 times a day for 30 seconds each time. The conditions and results of this verification are shown in fig. 21-26. The total length of the facial muscle exerciser 21 used in the verification was 540mm, the length of the elastic plate 22 was 380mm, the thickness was 6mm, the thickness of the coating layer 23 of thermoplastic polyurethane was 6mm, and the weight of the weight 30 was 92 g. The face of the subject was photographed before, i.e., before and after the verification test was completed, i.e., after use, and the photographic images were analyzed by using software of "Mirror" model manufactured by CanfieldScientific, usa as 2-dimensional skin surface analysis software to measure the change state before and after the verification test, and the results thereof were plotted.

Fig. 21(a), (b) and 22 show experimental results for verifying the elevation of the mouth angle of the subject. That is, the distance 106 between the corners of the mouth and the pouches of 67 subjects in the photographs before and after use was measured, and the change in the distance 106 before and after use was calculated. The results of calculation of the 67 names before and after use were averaged, and the results are plotted in fig. 22. As is apparent from fig. 22, the exercise effect is recognized since the distance 106 is shortened by 0.6mm on average after use with respect to before use and the angle of mouth is raised.

Fig. 23(a), 23(b), and 24 are experimental results for verifying cheek elevation. That is, a horizontal line 107 passing through the intertragic notch and a horizontal line 108 passing through the corner of the mouth were set in the side face photographs of 67 subjects before and after use, the longest point 110 on the cheek contour with the intertragic notch as the starting point 109 between the 2 horizontal lines 107, 108 was determined, and the before-use and after-use states with respect to the distance from the starting point 109 to the longest point 110 were measured. However, 9 cases in which the intertragic notch and the cheek contour were not obvious were excluded from the verification subjects, and 58 data items were averaged. In this case, the exercise result, i.e., the position of the longest point 110, is moved upward. Then, the change between the 67 samples before and after use was calculated and plotted in fig. 24. As is apparent from fig. 24, since the distance after use is shortened by approximately 0.7mm on average relative to that before use, the exercise effect is recognized.

Fig. 25(a), (b) and 26 are experiments to verify the face line tightening effect. That is, a horizontal line 111 passing through the root of the nasal prong was set in 67 front photographs before and after use, and a face contour 112 below the horizontal line 111 was set. Then, the area between the horizontal line 111 and the face contour 112 before and after use is calculated and the change thereof is calculated, and it is made into a graph in fig. 26. However, in this case, 11 names in which the face contour 112 is not obvious are excluded from the verification target, and the data of 56 names are averaged. As is evident from fig. 26, a reduction in area of approximately 0.7 square centimeters before use relative to an average reduction after use is recognized.

As described above, since the size of each portion of the face is made short by using the facial muscle exerciser 21, the rejuvenation effect is recognized.

(other embodiments)

Hereinafter, other embodiments of the present invention will be described focusing on differences from the above embodiments.

The embodiment shown in fig. 19 is a facial muscle exerciser 21 in which the weight 30 in the above-described real-time mode is omitted. Large-area portions 122 are formed at both ends of the elastic plate 22, and the large-area portions 122 serve as a load-bearing function in place of the weight 30. In this configuration, although not shown, the through hole 222 of the elastic plate 22 and the bush 26 are provided, and the bush 26 is preferably provided at the distal end portion of the large area portion 122.

In the embodiment of fig. 19, since the number of parts is reduced, the configuration is simplified.

(modification example)

The above embodiment may be modified and embodied as follows.

The elastic plate 22 is exposed without providing the coating layer 23 covering the elastic plate 22, and the weight 30 constituting the weight portion 25 is directly fixed to the elastic plate 22. In this case, the weight 30 is fixed by using a bolt or fitting a protrusion formed on the weight 30 into a hole of the elastic plate 22. The weight 30 may be wound, bent, or formed to have a large area so that the weight 30 becomes the weight required for the elastic plate 22.

The material of the elastic plate 22 may be changed to another material, for example, carbon fiber, FRP (fiber reinforced plastic), or the like, instead of the steel plate.

The coating layer 23 of the elastic plate 22 may also be omitted.

As shown by double-dashed lines in fig. 1, relaxation members 32 are provided at both end positions of the elastic plate 22 in the vicinity of the holding hole 29. The relaxation member 32 is formed of a synthetic resin harder than the coating layer 23, and is placed in the coating layer 23 so as to have a surface continuous with the surface of the coating layer 23. Pins, not shown, projecting from the inner surface of the relaxation member 32 are fitted into the small holes 224 at both ends of the elastic plate 22, thereby fixing the relaxation member 32. The relaxation member 32 relaxes the concentrated stress acting on both ends of the elastic plate 22, thereby preventing the occurrence of cracks or the like of the coating layer 23.

As the coating layer 23 of the elastic plate 22, a synthetic resin plate may be bonded to one or both of the front and back surfaces of the elastic plate 22, a synthetic resin may be injection-molded in a thin plate shape on one or both of the front and back surfaces, or a tape may be applied to the elastic plate 22.
