(First embodiment)

As shown in Fig. 1, the face muscle trainer 21 of the first embodiment uses a user's lips to bite, and the user shakes the face muscle trainer 21 up and down, thereby absorbing the user's orbicular muscles and The facial muscles of the buccal muscles, the laughing muscles, the big muscles, the small muscles, etc., which are connected to the orbicularis muscles, are trained.

As shown in FIGS. 3, 4, and 8, the face muscle trainer 21 is provided with a linear plate-shaped elastic plate 22 including a leaf spring made of a steel plate. As shown in FIGS. 9 and 11, a core body 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 molding the elastic plate 22 as an insert. The core 27 is formed with a projection 272 that protrudes from the edge of one side of the elastic plate 22. An interface member 28 formed in a hollow shape is detachably attached to the protruding portion 272 of the core body 27, and the engaging member 24 for biting the lip is formed by the interface member 28 in the mounted state.

As shown in FIGS. 3, 6, and 8, the entire elastic plate 22 and the portion of the core 27 other than the protruding portion 272 are molded by a covering material 23 containing a synthetic resin such as polyurethane. The covering member 23 is composed of a softer core 27 and a softer one. A pair of through holes 222 are formed on both end sides of the elastic plate 22, respectively. The through hole 222 on the inner side allows the synthetic resin to enter during the molding of the covering member 23, and functions to strengthen the combination of the elastic plate 22 and the covering member 23. As shown in FIGS. 5 and 6, the bushing 26 is fitted in the through hole 222 on the outer side, and protrudes from both the front and back sides of the elastic plate 22. However, the bushing 26 is formed at a height that is not exposed on the surface of the covering member 23. Small holes 224 are respectively formed at both ends of the elastic plate 22. The small hole 224 also allows the entry of synthetic resin to enhance the bomb The function of the combination of the plate 22 and the covering material 23.

Further, a pair of right and left arms 31 are formed by the elastic plates 22 and the covering members 23 on the left and right sides of the core body 27. A weight portion 25 is provided on the arm 31 and at the front end of the covering member 23, respectively.

Next, as shown in FIG. 1, by using the lip bite-holding portion 24 and rocking the face muscle trainer 21 as a whole, the arms 31 are generated by shaking according to the load of the weight portion 25 and the elasticity of the elastic plate 22. The resonance further vibrates up and down. Here, the resonance means that the vibration of the number of vibrations within the predetermined range is applied to the holding portion 24, and the arm 31 largely vibrates. In particular, it is more preferable to bend the end portion of the arm 31 to a position higher than the height of the holding portion 24. Thereby, the load acts on the facial muscles of the user who bites the holder 24 to train the facial muscles.

As shown in FIGS. 9 to 13, a concave-convex portion 271 for locking and holding the interface member 28 is formed on the outer peripheral surface of the core body 27. The interface member 28 is formed of a soft synthetic resin such as polyurethane which is softer than the core 27 and which is not easily slidable. An uneven portion 281 that can be engaged with the uneven portion 271 of the core body 27 is formed on the inner peripheral surface of the interface member 28. A recessed portion 282 for lip biting is formed below the central portion of the outer peripheral surface of the interface member 28. As shown in FIG. 13, in the portion of the recessed portion 282, the outer peripheral surface of the interface member 28 is formed in an elliptical shape having a long diameter extending in the left-right direction. Thereby, the curvature of the upper and lower positions of the depressed portion 282 is smaller and flatter than the two positions on the left and right sides, and thus it is easy to bite. A concave portion 283 is formed on the outer peripheral surface of the front end portion of the interface member 28. A spherical convex portion 284 is formed on the front end surface of the interface member 28.

A pair of flanges 285 on the front and back sides of the arm 31 are formed at the base end of the interface member 28. The flange 285 protrudes from the other portion of the interface member 28, as shown in FIG. 9, on the setting surface 100 for placing the face muscle trainer 21 on the table or the like. At this time, the flange 285 is in contact with the above-described setting surface 100 such that the interface member 28 faces obliquely upward. Thereby, the portion of the interface member 28 for the lip bite can be prevented from coming into contact with the setting surface 100, and can be kept clean.

The interface member 28 having a plurality of different outer dimensions and the like is prepared, and the user can select an appropriate interface member 28 according to the size and shape of the mouth, and perform fitting with respect to the outer side of the core body 27. The interface member 28 is softer than the core 27, and its hardness is, for example, 60 degrees in a durometer according to Type A of JIS (Japanese Industrial Standard) K6253. Further, the body of the face muscle trainer 21 other than the weight 30, that is, the body composed of the elastic plate 22, the covering member 23, the core body 27, and the interface member 28 has a weight of about 50 to 500 g (g). Further, the weight of the weight 30 is about 3 to 120 g.

As shown in FIGS. 5 and 14, retaining holes 29 are formed at both ends of the covering member 23. The two weight portions 25 are formed of weight blocks 30 that are detachably attached to the respective holding holes 29. Further, a plurality of weights 30 having different weights are prepared, and the weight 30 of any weight is selected according to the degree of training required by the user, and is detachably attached to the holding hole 29.

The face muscle trainer 21 of the present embodiment is provided with a cover 51 which together with the face muscle trainer 21 constitutes a face muscle trainer assembly.

As shown in Fig. 2, Fig. 15, Fig. 16, and Fig. 18, the casing 51 is made of a synthetic resin such as transparent or translucent polypropylene, polyethylene, or polyamide resin, and is provided via a central one body hinge 52. A half-divided cover piece 53, 54. The cover sheets 53, 54 are formed by one of the main bodies, and the other constitutes a cover. In the present embodiment, the cover piece 53 on the lower side of Fig. 15 is used as the main body, and the upper cover piece 54 is used as the cover. The two cover sheets 53, 54 are each formed in a concave shape, and a housing space 511 is formed between the two. Moreover, the holding portion 24 of the face muscle trainer 21 and the central portion of the covering member 23 It is housed in the accommodating space 511, and this portion is covered by the cover 51. A locking claw 55 is formed on one of the cover pieces 53 , and a support portion 56 for engaging the locking claws 55 is formed on the other cover piece 54 . When the cover pieces 53 , 54 are closed, The cover 51 is held in a closed state by the engagement of the locking claw 55 and the support portion 56.

A recess 58 is formed in a side wall of the two cover sheets 53, 54. Moreover, the two recesses 58 are formed in the opening 59 of the cover sheets 53, 53 to avoid interference with the arm 31 for passing the arm 31 thereof, and at the edge of the opening 59 and the periphery of the arm 31. A gap 60 is formed between the faces. Further, in the opening 59, the edge portion of the opening 59 is formed in an arc shape in a cross section so as not to have an edge, or the edge portion is formed thicker so that the contact area with the arm 31 is wider, or the edge portion is formed. It is thickened and formed in an arc shape in cross section, whereby damage to the arm 31 can be prevented.

Next, a method of using the face muscle trainer 21 configured as described above will be described.

As shown in FIG. 2, when the face muscle trainer 21 is not in use, a cover 51 is attached to a central portion of the face muscle trainer 21 to cover the holding portion 24. Thereby, the portion for the lip bite, that is, the holding portion 24 can be cleanly maintained. In addition, since the cover 51 is formed substantially along the outer surface of the interface member 28, the face muscle trainer 21 in the installed state of the cover 51 can be housed in a dedicated case, thereby carrying and storing the face muscle trainer. twenty one.

When the face muscles are trained by the face muscle trainer 21, the cover 51 is removed. Further, according to the degree of training required by the user of the face muscle trainer 21, the interface member 28 of the desired outer size is mounted in advance on the core 27, and the required weight is installed in the holding hole 29 of the two weight portions 25. Weight block 30. In this state, the depressed portion 282 of the holding portion 24 is bitten to the lips and the face is shaken downward. move. As a result, in the state where the weight of the face muscle trainer 21 acts on the lips, the two weight portions 25 resonate up and down via the elastic plate 22 including the leaf spring, and the vibration is transmitted to the holding portion 24. Thereby, the load is applied to the facial muscles via the lips, and the facial muscles are trained.

In this case, the grip portion 24 protrudes from the side edge of the arm 31 and is disposed at a position displaced outward from the side edge. Therefore, the face muscle trainer 21 is bitten to the lips in a single holding state, so that the load on the lips is increased. Thereby, the load generated by the resonance acts effectively as a load on the facial muscles, thereby effectively training the facial muscles. At this time, since the recessed portion 282 is formed in a horizontally elliptical cross-sectional shape, the interface member 28 can be held in a state in which the nozzle is opened in a circular shape. By holding the interface member 28 in a state in which the mouth is circularly opened, the load generated by the resonance can be transmitted to the entire orbicularis muscle. In addition, since the expression muscles such as the laughing muscles are connected to the orbicularis muscles, it is also possible to train the laughing muscles and the like via the orbicularis muscles, thereby enabling efficient training.

In the face muscle trainer 21 of the present embodiment, the elastic plate 22 is molded by the covering material 23 of the synthetic resin. Therefore, when the arm 31 is bent and resonated, the movement of the arm 31 to be obtained for training can be suppressed, For example, the distortion or microvibration of the elastic plate 22. Thereby, the movement which hinders the transmission of the lips of the user can be reduced, and the face muscle trainer 21 can be comfortably used. Further, instead of molding the entire elastic plate 22, the synthetic resin sheet or sheet may be adhered to one side of the front and back sides or one of the front and back sides by adhesion or the like.

The interface member 28 has rubberiness that is not easily slid and moderate in hardness. Therefore, it is easy to bite and the load generated by the vibration of the arm 31 can be transmitted to the lips. If the interface member 28 is too stiff, the interface member 28 is not adapted to the lips and is not easily bitten. On the contrary, if it is too soft, even if it can bite, it is not easy to face the face muscle trainer in 21 dimensions. It is in a steady state, and the vibration of the arm 31 is absorbed, and the load for training is reduced.

In the case where the face muscle trainer 21 is used by a different user, the interface member 28 on the core 27 is exchanged for other interface members 28 having different outer dimensions, etc., even for users whose mouths are different in size and shape. It is also possible to share a face muscle trainer 21.

Moreover, depending on the strength of the facial muscles or the degree of training, the weights 30 in the holding holes 29 of the weight portion 25 can be exchanged for other weights 30 of different weights.

After the training is completed, the interface member 28 can be removed from the core body 27 as needed for cleaning, and the cleaned interface member 28 can be mounted to the core body 27 again. Thereby, the interface member 28 can be cleanly and hygienically held. The cover 51 is then mounted on the exerciser 21 to cover the interface member 28.

As described above, by covering the cover member 28 with the cover member 51, the interface member 28 can be maintained in a clean state when carrying or storing the exerciser 21. Further, by accommodating the separate interface member 28 detached from the core body 27 in the casing 51, the interface member 28 can be kept in a clean state when the interface member 28 is carried or stored.

Hereinafter, a method of manufacturing the face muscle trainer 21 of the present embodiment will be described.

First, the core body 27 is injection-molded into the central portion of the elastic plate 22 shown in Fig. 7 by using the elastic plate 22 as an insert.

Then, the bushing 26 is fitted into the through hole 222 in one of the both end sides of the elastic plate 22. Thereby, the bushing 26 protrudes from the front and back sides of the elastic plate 22.

Then, as shown in FIG. 6, the elastic plate 22 is set in the molding die 101, and the synthetic resin as the coating material 23 is emitted into the mold 101. At this time, at the initial stage of the injection of the synthetic resin, the injection pressure thereof is unevenly applied to the elastic plate 22, and the pressure is applied. The force temporarily acts unevenly on the elastic plate 22. Therefore, the elastic plate 22 may be bent, and scratches or the like may be caused to the molding surface of the cavity 102 of the molding die 101 due to the edge of the end edge or the like. However, in the present embodiment, when the elastic plate 22 is bent, the bushing 26 abuts against the molding surface of the cavity, and the abutment of the elastic plate 22 can be avoided.

Thereby, it is possible to prevent the occurrence of scratches on the molding surface of the cavity 102. In a state in which the synthetic resin is filled in the cavity 102, since the injection pressure uniformly acts on the entire elastic plate 22, the bending of the elastic plate 22 returns to the original shape, and the elastic plate 22 linearly extends in the central portion of the cavity 102. . Thereby, after the molding is completed, the elastic plate 22 is molded at a predetermined position in the formed covering material 23.

In the face muscle trainer 21 of the present embodiment, when the grip portion 24 is bitten by the lips and vibrated up and down, the arms 31 on both sides resonate while being curved. In this case, in the present embodiment, the length of the arm 31, the weight of the weight portion 25, the elastic modulus of the arm 31 including the elastic plate 22, the spring constant, and the like are set such that the holding portion 24 is less than 6.50 Hz. When the vibration number of (Hz) vibrates, the arm 31 can resonate. Therefore, the user can bite the lip to resonate the arm 31, and the load can be used for effective training. On the other hand, in the case of the vibration number exceeding 6.50 Hz, that is, when the holding portion 24 is slightly reciprocated, since the arm 31 does not resonate, the resonance of the arm 31 is the same as the state in which the rigid body which is not bent is vibrated. The resulting load is not transmitted to the lips and does not provide effective training.

Further, in the face muscle trainer 21 of the present embodiment, the bending rate of the arm 31 in the stationary state toward the lower side, that is, the bending amount of the length b of the arm 31 as shown in Fig. 17 toward the lower end of the arm 31 is shown. a 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. Thereby, the user can obtain effective training effects. In contrast, the bending rate is 4.8%. In the case where the rigidity of the arm is high and it is not easy to bend, since it is difficult to resonate, it is difficult to obtain an effective training effect.

Further, in the face muscle trainer 21 of the present embodiment, the load applied to the grip portion 24 when the resonance acts on the arm 31 is set to less than 7.4 Newtons (N). Therefore, when the holding portion 24 is vibrated up and down to resonate the arm 31, an appropriate load can be applied to the user, and an effective training effect can be obtained. On the other hand, when the load is 7.4 N or more, the load is too high and vibration is difficult.

Hereinafter, the results of verification of the action of the face muscle trainer 21 of the embodiment will be described based on Tables 1 to 6. In this verification, a plurality of elastic plates 22 which will be described later in Fig. 20(a) are used. A protruding portion 223 is formed in an intermediate portion of the elastic plate 22 in the longitudinal direction. Further, various weights (not shown) to be described later are detachably attached to both ends of the elastic plate 22 by screws or chucks.

In Table 1, three types of thicknesses of 0.6 mm (mm), 0.8 mm, and 1.0 mm, and lengths of 300 mm, 400 mm, 500 mm, 600 mm, 700 mm, 800 mm, and 1000 mm are prepared, and a total of 21 types of elastic plates 22 are prepared. . Further, five types of weights of 6.0 g (g), 11.5 g, 23.5 g, 48.0 g, and 92.0 g were prepared, and the weights were attached to both ends of the 21 types of elastic plates 22 to prepare 105 types. Sample 120 (see Fig. 20(b)). Then, as shown in Fig. 20 (b), the protruding portion 223 of the elastic plate 22 is sandwiched by a loose flat vibration testing machine 103 manufactured by Ito Seiki Co., Ltd., and various vibrations having an amplitude of 20 mm in the vertical direction are applied to the sample 120. The number of applied vibrations per second when the maximum amplitude is generated on the arms on the left and right sides of the elastic plate 22 is described in Table 1 above. The value of the number of applied vibrations at the time of resonance is determined in accordance with the display of the display unit (not shown) of the vibration tester 103 described above. In addition, the presence or absence of the resonance system depends on the visual observation.

Then, the various samples 120 described above are removed from the vibration tester 103, and the interface member 41 is attached to the protruding portion 223 of the elastic plate 22. The interface member 41 has the same size and hardness as the above-described holding portion 24, and corresponds to the holding portion 24. The sample 120 was subjected to a somatosensory test using 10 subjects, and as shown in Table 2, the results were divided into 4 grades. The four grades are obtained based on the results of the feelings of six or more subjects, that is, resonance (level 4), resonance (level 3), resonance (level 2), and resonance are particularly likely to occur. (Grade 1). "There is no resonance" means that the arm 31 cannot be resonated, and "resonance is unlikely to occur" means that it is felt that resonance can occur but resonance is required to generate resonance. Furthermore, "unmeasurable" in Table 1 indicates that the frequency of resonance cannot be judged because it is outside the measurement range of the measuring machine. Thereby, it was confirmed that the arm of the elastic plate 22 can resonate even if the number of vibrations per second is 1.17 or less.

As is apparent from Tables 1 and 2, in the case where the above-mentioned interface member 41 vibrates at a vibration number less than 6.50 Hz, the arm of the elastic plate 22 can resonate with the sample 120, the user is less likely to be generated. Resonance, but can make the arm resonate, so that the facial muscles can be trained.

Further, in the case where the arm 120 can resonate when the interface member 41 vibrates at a vibration number less than 5.00 Hz, the user can easily resonate the arm. More preferably, the user can more easily resonate the arm when the arm is capable of resonating the sample 120 when the interface member 41 vibrates at a vibration number less than 3.50 Hz.

Further, under the above conditions, in the case where the arm can resonate when the interface member 41 vibrates at a vibration number exceeding 4.67 Hz, the user does not easily resonate the arm but can resonate. Face muscle training.

In the case where the arm can resonate the sample 120 when the interface member 41 vibrates at a vibration number exceeding 3.33 Hz, the user can easily resonate the arm, thereby allowing the face muscle to be trained. Further, it is particularly preferable that the arm is more likely to resonate when the arm 120 is capable of resonating when the interface member 41 vibrates at a vibration number of 1.17 Hz or more. Even if it is less than 1.17 Hz, it can resonate. However, since the number of vibrations per second of the arm is small, the exercise efficiency is lowered, which is not preferable.

In the case where the arm 120 is capable of resonating when the interface member 41 vibrates at a vibration number of 6.33 Hz or less, the resonance is less likely to occur, but the user can resonate the arm and can train the face muscle.

Further, it is preferable that the arm 120 can resonate when the interface member 41 vibrates at a vibration number of 3.50 Hz or more and 4.67 Hz or less. Particularly preferably, the arm can be generated when the interface member 41 vibrates at a vibration number of 1.17 Hz or more and 3.33 Hz or less. Resonance sample 120.

It is also preferable that the sample 120 which resonates when the interface member 41 vibrates at a vibration number of 1.17 Hz or more and 3.40 Hz or less. It is also possible to use a sample 120 in which the arm can resonate when the interface member 41 vibrates at a vibration number of 1.17 Hz or more and 4.80 Hz or less. The training can also be performed in the sample 120 in which the arm can resonate when the interface member 41 vibrates at a vibration number of 1.17 Hz or more and 6.40 Hz or less.

Further, when viewed from another viewpoint, the sample 120 which can resonate when the arm member vibrates at the number of vibrations in the range of 1.17 Hz or more and 6.33 Hz or less can be used for training. The arm generates resonance when the interface member 41 vibrates with a vibration number in the range of 5.0 Hz or more and 6.33 Hz or less.

It is also preferable that the arm can resonate when the interface member 41 vibrates at a vibration number in the range of 3.50 Hz or more and 6.33 Hz or less. Further, it is preferable that the arm can resonate when the interface member 41 vibrates at a vibration number in the range of 1.17 Hz or more and 4.67 Hz or less.

In Table 3, the sample 120 is set to have 18 types of elastic sheets 22 having a total thickness of 0.6 mm, 0.8 mm, and 1.0 mm, and a total length of 400 mm, 500 mm, 600 mm, 700 mm, 800 mm, and 1000 mm. A sample of 90 types combined with weights of 5 types of weights of 6.0 g, 11.5 g, 23.5 g, 48.0 g, and 92.0 g. Further, as shown in FIG. 17, the amount of bending a of the right and left arms of the elastic plate 22 in the natural state is measured in units of mm, and the value is expressed as a ratio with respect to the length b of the arm of the elastic plate 22, that is, the bending rate. 3. Then, in the same manner as described above, the skin test of each of the samples 120 was performed by 10 subjects, and the results were the same as in Table 2, and the results were classified into four grades in Table 4.

Thereby, in the case of the sample 120 in which the bending rate of the arm in a stationary state exceeds 4.8%, the user can resonate the arm. Further, in the case of the sample 120 having a bending ratio of more than 8.1%, it is preferable that the arm is easily resonated. More preferably, in the case of the sample 120 having a bending ratio of more than 15.0%, it is easier to cause the arm to resonate. Further, when the bending rate is less than 8.3%, resonance is unlikely to occur, but the arm can be resonated. to When the bending rate is less than 15.2%, resonance tends to occur, which is preferable. It is particularly preferable that the resonance becomes particularly prone to resonance when the bending rate is less than 60.8%.

If observed from other viewpoints, resonance can occur when the bending rate is 5.0% to 60.8%. Specifically, the following results are shown, that is, resonance can be generated when the bending rate is 5.0% to 8.1%, and resonance can be easily generated when the bending rate is 8.3% to 60.8%, and the bending rate is 8.3. Resonance is easy to occur in the case of %~15.0% and 60.8%, and resonance is particularly likely to occur in the case of 15.2% to 48.8%. As described above, it is presumed that resonance is likely to occur when the bending rate is 60.8%. However, if the bending rate greatly exceeds the value of 60.8%, the movement of the interface member 41 is less likely to be transmitted to the elastic plate 22, and resonance is less likely to occur.

In the same manner as described above, the sample 120 is set to have three types of thicknesses of 0.6 mm, 0.8 mm, and 1.0 mm, and total lengths of 400 mm, 500 mm, 600 mm, 700 mm, 800 mm, and 1000 mm, which are 18 types. The elastic plate 22 is a 90-type sample which is combined with five types of weights of 6.0 g, 11.5 g, 23.5 g, 48.0 g, and 92.0 g. Then, as shown in Fig. 20 (b), the protrusion 223 of the elastic plate 22 is sandwiched from above and below by the vibration tester 103, and the elastic plate 22 is made by the vibration tester 103 under the same conditions as those in the above Table 1. Vibration up and down. At this time, the maximum load acting on the sample 120 is detected by the strain sensor 104. As the strain sensor, the product name Strain Gauges TYPE: FLA-5-11-3L of the Tokyo Instruments Research Institute Co., Ltd. was used. Incidentally, the load acting on the sample 120 is affected by the load of the elastic plate 22 and the weight, the repulsive force of the elastic plate 22, and the acceleration applied by the vibration. Further, the testing machine 103 sets the output of the stationary state strain sensor 104 to the reference value 0, and applies to the protruding portion 223 of the elastic plate 22 according to the strain amount of the elastic plate 22 detected by the strain sensor 104. The load is measured. and The maximum value of the load calculated in this manner is shown in Table 5 in addition to the portion of the force applied to the elastic plate 22. Then, using each sample 120, the somatosensory test was performed by 10 subjects in the same manner as described above, and the result was divided into irresistible resonance (level 3), resonance was not easy but resonance (level 2), and resonance was easy (gradation) 1) 3 levels. Table 6 shows this rating.

As a result, in the case where the arm can resonate with the sample 120 when the load is less than 7.4 N, the user can resonate the arm, in the case where the arm can resonate with the sample 120 when the load is less than 3.9 N. It is especially prone to resonance. Furthermore, it is presumed that resonance is likely to occur in the case of the sample 120 in which the arm can resonate when the load is less than 1.5N.

If viewed from other viewpoints, the user can resonate the arm with the arm at the load in the case where the arm can resonate with the sample 120 in the range of 3.9 N to 7.1 N applied to the interface member 41. Can be generated in the range of 1.5N~3.8N In the case of the sample 120 of resonance, it is particularly easy to resonate the arm. In the case where the arm is capable of generating a resonance sample 120 in the range of 1.5 N to 3.85 N, the arm can also resonate. When the load is less than 1.5N, the arm can be resonated, but the load is small and the exercise efficiency is small.

By arbitrarily setting various conditions such as the length of the arm 31 of the face muscle trainer 21 and the weight of the weight 30, the face muscle trainer 21 which displays various conditions described in Tables 1 to 6 can be specified. Chemical. Such a face muscle trainer 21 can obtain the same effect as the above verification result.

Further, Table 7 describes the spring constant (g/mm) of the elastic plate 22 used in the above various tests, and the elastic plate 22 is set to have three types of thicknesses of 0.6 mm, 0.8 mm, and 1.0 mm, and has a total length of 300 mm. The total of 7 types of 400mm, 500mm, 600mm, 700mm, 800mm, and 1000mm is 21 types. As is apparent from Table 7, the lowest spring constant is 0.23 g/mm, and the highest spring constant is 39.35 g/mm. However, it is not limited to these spring constants, and any spring constant can be set. Further, the face muscle trainer can be specifically implemented using the spring constant of Table 7 or the elastic plate 22 of any spring constant. The arbitrary spring constant is a spring constant that fills in the value between the respective values of the spring constants of Table 7, or a spring constant that exceeds the value of the maximum spring constant value of Table 7 or a spring constant that is less than the value of the minimum spring constant value.

Figures 27 to 32 show the verification conditions and results. The face muscle trainer 21 for verification is composed of the body of the face muscle trainer 21 except the weight 30, that is, the elastic plate 22, the covering member 23, the core body 27, and the interface member 28, and the weight of the body is 120 g. The total length is 540 mm, the length of the elastic plate 22 is 380 mm, the thickness is 0.6 mm, the thickness of the thermoplastic 23 covering material 23 is 6 mm on average, and the weight of the weight 30 is 18 g, 23 g, and 28 g. In addition, before the use of the verification test, and after the use of the verification test, the face of the subject was photographed, and the two-dimensional skin surface analysis software, the trademark name "Mirror" manufactured by Canfield Scientific, USA, was used. The image measurement verifies the state of change before and after the test and the results are graphed.

Fig. 27 (a) (b) and Fig. 28 are diagrams for verifying the mouth angle of the subject. That is, in the photos before and after use, the mouth angles of 67 subjects were measured. The distance 106 between the ends of the eyes is used to calculate the change in distance 106 before and after use. Then, the calculation results of 67 before and after use were averaged and plotted in Fig. 28. As can be seen from Fig. 28, the distance 106 was shortened by about 0.6 mm on average after use, and the mouth angle was raised to confirm the training effect.

Fig. 29 (a) (b) and Fig. 30 are diagrams for verifying the riser of the cheek portion. That is, in the photo of the face of the face before and after use of 67, the horizontal line 107 passing through the tragus between the tragus and the horizontal line 108 passing through the corner of the mouth are set, and the inter-screen notch is determined between the two horizontal lines 107 and 108. As the longest point 110 on the cheek contour of the starting point 109, the state from the starting point 109 to the longest point 110 is measured before and after use. However, the nine people who were unclear in the outline of the screen and the outline of the cheek were excluded from the verification object, and the data of 58 were averaged. In this case, as a result of the training, the position of the longest point 110 moves upward. Then, the change of 67 before and after use was calculated, and a graph was made in FIG. As can be seen from Fig. 30, the above distance was shortened by about 0.7 mm on average after use, and the training effect was confirmed.

Fig. 31 (a) (b) and Fig. 32 are diagrams for verifying the tightening effect of the face line. That is, in the front photograph of 67 before and after use, the horizontal line 111 passing through the root of the nose pad is set, and the contour 112 of the face on the lower side of the horizontal line 111 is set. Then, the area between the above-mentioned horizontal line 111 and the contour 112 before and after use is calculated, and the change is calculated, and a graph is formed in FIG. However, at this time, the 11 photos of the outline 112 of the face were excluded from the verification object, and the data of 56 were averaged. As can be seen from Fig. 32, it was confirmed that the area of the average of about 0.7 cm ² was reduced after use with respect to use.

As described above, by using the face muscle trainer 21, the size of each part of the face is shortened, and the effect of resisting the old spring is confirmed.

Further, a large-area portion 122 is formed at both end portions of the elastic plate 22, and a load function in which the weight portion 30 is replaced by the large-area portion 122 is provided. In the case of this configuration, although not shown, it is preferable that the elastic plate 22 is provided with the through hole 222 or the bushing 26, and the bushing 26 is provided at the front end portion of the large-area portion 122.

In the present embodiment, the number of components is reduced and the structure is simplified.

(Third embodiment)

Next, a third embodiment of the present invention will be described with reference to Figs. 21 to 26, focusing on differences from the above embodiments.

As shown in FIGS. 21 and 22, a large-area portion 122 including the covering member 23 is formed at both end portions of the covering member 23. The elastic plate 22 is formed to reach the length of the central portion of the large-area portion 122. The elastic plate 22 is formed such that its thickness dimension and width dimension gradually decrease as it goes from the central portion toward the front end in the longitudinal direction.

As shown in FIGS. 22 and 23, a weight piece 330 including a metal plate is embedded in both ends of the large-area portion 122 of the face muscle trainer. A first through hole 331 and a pair of second through holes 332 are formed in the weight piece 330, and the second through hole 332 is located in the covering member 23. The synthetic resin constituting the covering member 23 enters the second through hole 332 to secure the bonding strength between the weight piece 330 and the covering member 23. A notch 333 is formed on both sides of the front and back sides of the weight piece 330, and the first through hole 331 is located in the notch 333.

A synthetic resin clip 334 is formed in the notch 333, and the clip 334 is colored differently from the cover 23, and the outer surface and the cover 23 are colored. The outer surface is continuous. As shown in FIGS. 24 to 26, in the clip 334, the pair of holding pieces 335 are coupled via the connecting portion 338, and the holding piece 335 as a whole is formed in an acute angle on the side surface. A clamping protrusion 336 is formed at a root portion of the two clamping pieces 335, and the weight piece 330 is held by the clamping protrusions 336. A fitting protrusion 337 is formed on the inner surface of the front end of the two holding pieces 335, respectively. The fitting projection 337 is fitted into the first through hole 331 of the weight piece 330. The clip 334 is fixed to the weight piece 330 by the fitting.

The face muscle trainer 21 having the above configuration is used in the same manner as the face muscle trainer 21 of the above-described embodiment.

Further, in the third embodiment, the following effects are obtained.

(1) Since the weights other than the main body as in the first embodiment are not provided, the number of parts is small, and the manufacturing cost can be reduced.

(2) A weight piece 330 is embedded at both ends of the arm 31. Thereby, the weight of the weight piece 330 can be used to greatly vibrate both ends of the arm 31, and the training can be performed efficiently.

(3) A space is provided between both ends of the arm 31 and the weight piece 330. Therefore, the synthetic resin in the space portion is easily bent, and both ends of the arm 31 are easily vibrated by the bending, and the training can be effectively performed by using this characteristic. Further, a space is provided between both ends of the arm 31 and the weight piece 330, so that even if the weight piece 330 or the surrounding material 23 around the weight piece 330 is subjected to small vibrations which are not related to training due to the movement of the weight piece 330, a part of the vibration Or most of it can still be absorbed by the covering material 23 of the above-mentioned interval. Thereby, the bending motion of the arm 31 becomes more elastic and can be easily used.

(4) Since the thickness dimension and the width dimension of the elastic plate 22 are gradually decreased toward the front end from the center portion in the longitudinal direction, both end portions of the elastic plate 22 are easily bent. Thereby, both ends of the arm 31 can be largely vibrated, and the elasticity of both ends of the elastic plate 22 can be effectively utilized for training.

(5) At the time of molding of the covering member 23, the weight piece 330 is held in a hollow state by a neutron chuck in a molding die (not shown). Then, a notch 333 exposing the weight piece 330 is formed at both ends of the covering member 23 by demolding with the end of molding. Thereby, the notch 333 can be simply used to mount the clip 334 as a design highlight.

(variation)

Furthermore, the above embodiment may be modified and implemented as follows.

The covering member 23 covering the elastic plate 22 is not provided, and the elastic plate 22 is exposed, and the weight 30 constituting the weight portion 25 is directly fixed to the elastic plate 22. In this case, the fixing of the weight 30 is performed by using a screw or fitting a projection formed on the weight 30 into the hole of the elastic plate 22. Further, the weight 30 may be configured by winding, bending, or setting the weight 30 to a large area so that the end portion of the elastic plate 22 has a desired weight.

Instead of the steel sheet, the material of the elastic sheet 22 may be changed to other materials such as carbon fiber or FRP (glass fiber reinforced plastic).

As described above, the material of the elastic plate 22 is changed to another material such as carbon fiber or FRP (glass fiber reinforced plastic) instead of the steel sheet, and the covering material 23 is omitted.

The covering material 23 of the elastic plate 22 is omitted.

As shown by the two-dot chain line in FIG. 1, the cushioning member 32 is provided at both ends of the elastic plate 22 in the vicinity of the holding hole 29. The cushioning member 32 is made of a synthetic resin which is harder than the covering material 23, and is embedded in the covering member 23 so as to have a surface continuous with the surface of the covering member 23. Further, the pin (not shown) protruding from the inner side surface of the cushioning member 32 is fitted to the small hole 224 at both ends of the elastic plate 22 to fix the cushioning member 32. The cushioning member 32 is for buffering the concentrated stress acting on both ends of the elastic plate 22 to prevent the turtle of the covering material 23 Cracked and so on.

As the covering material 23 of the elastic plate 22, a synthetic resin plate is adhered to one side or both sides of the front and back sides of the elastic plate 22, and the synthetic resin is projected into a sheet shape on one or both sides of the front and back, or the tape is wound around Elastic plate 22.
