Definitions

  • the present invention relates to a facial muscle training tool used for training facial muscles of a human face such as the orbicularis oris muscle.
  • a facial muscle training tool of this type conventionally has such a structure as one disclosed in Patent Document 1 for example.
  • an orally held portion to be held with lips is provided on both the front and back surfaces of a central portion of a strip-shape elastic plate.
  • a weight is fixed to each of opposite end portions of the elastic plate. With the orally held portion held with lips, the facial muscle training tool is shaken entirely up and down. By doing so, the repulsive force of the elastic plate resulting from the weight of each weight portion is transmitted to the orally held portion to train facial muscles.
  • Patent Document 1 Japanese Registered Design No. 1223289
  • Patent Document 1 discloses the entire shape of the facial muscle training tool. However, Patent Document 1 does not describe properties that the facial muscle training tool must have for training facial muscles properly. Hence, in some cases, a beneficial training function cannot be achieved by this conventional facial muscle training tool.
  • the present invention is intended to provide a facial muscle training tool capable of achieving a beneficial training effect.
  • the facial muscle training tool includes an elastically deformable portion and an orally held portion to be held with lips.
  • the orally held portion is provided at a middle position of the elastically deformable portion in a longitudinal direction of the elastically deformable portion.
  • the elastically deformable portion vibrates in resonance with vibration of the orally held portion in a vertical direction at a frequency of less than 6.50 hertz.
  • the present is capable of achieving a beneficial training effect.
  • a facial muscle training tool 21 is used for training the facial muscles of the user such as an orbicularis oris muscle, and a buccinator muscle, a risorius muscle, a greater zygomatic muscle, and a lesser zygomatic muscle connected to the orbicularis oris muscle by being held with the lips of the user and being swung up and down by the user.
  • the facial muscle training tool 21 includes an elastic plate 22 having a linear strip plate shape formed of a plate spring made of a steel plate.
  • a core 27 made of hard plastic such as polypropylene is fixed to a central portion of the elastic plate 22 in its longitudinal direction by means of molding using the elastic plate 22 as an insert.
  • the core 27 has a protruding portion 272 protruding from one edge of the elastic plate 22.
  • a hollow mouthpiece 28 is attached detachably to the protruding portion 272 of the core 27. While being attached to the protruding portion 272, the mouthpiece 28 forms an orally held portion 24 to be held with lips.
  • the elastic plate 22 in its entirety and a portion of the core 27 except the protruding portion 272 are molded using a covering 23 made of synthetic plastic such as polyurethane.
  • the covering 23 is made of a softer material than the core 27.
  • a pair of through holes 222 is formed in positions near each of opposite end portions of the elastic plate 22.
  • the inner through hole 222 functions to connect the elastic plate 22 and the covering 23 more tightly by allowing entry of the synthetic plastic during molding of the covering 23.
  • a bushing 26 is fitted in the outer through hole 222 to protrude from both the front and back surfaces of the elastic plate 22.
  • the bushing 26 is formed into a height that prevents exposure of the bushing 26 to the surface of the covering 23.
  • a small hole 224 is formed in each of the opposite ends of the elastic plate 22. The small hole 224 also functions to connect the elastic plate 22 and the covering 23 more tightly by allowing entry of the synthetic plastic.
  • the elastic plate 22 and the covering 23 on both the right side and the left side of the core 27 form a pair of right and left arms 31.
  • a weight portion 25 is provided at a tip portion of the covering 23 of each of the arms 31.
  • the orally held portion 24 is held with the lips and the facial muscle training tool 21 is entirely swung up and down. Then, both of the arms 31 are vibrated up and down in resonance with the swinging motion based on the load of the weight portion 25, the elasticity of the elastic plate 22 and the like.
  • the resonance vibration refers to large vibrating motion of the arms 31 resulting from application of vibration of a frequency within a predetermined range to the orally held portion 24.
  • the core 27 has an outer peripheral surface where a concave-convex portion 271 is formed for hooking and holding the mouthpiece 28.
  • the mouthpiece 28 is formed of soft synthetic plastic such as polyurethane that is softer and less slippery than the plastic for the core 27.
  • the mouthpiece 28 has an inner peripheral surface where a concave-convex portion 281 is formed that can be fitted to the concave-convex portion 271 of the core 27.
  • a depression 282 to be held with lips is formed at both the upper and lower central portions of the outer peripheral surface of the mouthpiece 28.
  • the outer peripheral surface of the mouthpiece 28 in a portion corresponding to the depression 282 is formed into an ellipse having a major diameter extending in the right and left direction.
  • the curvature of the depression 282 is smaller in two vertically separated positions than in two horizontally separated positions, so that the depression 282 is flat in the two vertically separated positions. This allows the depression 282 to be orally held easily.
  • a concave portion 283 is formed in the outer peripheral surface of a tip portion of the mouthpiece 28.
  • a convex portion 284 having a spherical surface is formed at a front end surface of the mouthpiece 28.
  • a pair of flanges 285 to be positioned on both the front and back sides of each arm 31 is formed at the base end of the mouthpiece 28.
  • the flanges 285 protrude further than the other portion of the mouthpiece 28.
  • the flanges 285 contact the installation surface 100 to point the mouthpiece 28 in an obliquely upward direction. This prevents a portion of the mouthpiece 28 to be held with lips from contacting the installation surface 100, so that the mouthpiece 28 can be kept clean.
  • mouthpieces 28 different in outer dimensions and the like are prepared.
  • the user is allowed to select an appropriate mouthpiece 28 according to the size or the shape of the mouth of the user, for example, and to fit the selected mouthpiece 28 to the core 27 from outside.
  • the mouthpiece 28 is softer than the core 27 and has hardness of 60 degrees measured using a type A durometer conforming to the JIS (Japanese Industrial Standards) K6253, for example.
  • the body of the facial muscle training tool 21 except the weight 30, specifically, the body including the elastic plate 22, the covering 23, the core 27, and the mouthpiece 28 has a weight from about 50 to about 500 grams (g).
  • the weight 30 has a weight from about 3 to about 120 g.
  • a holding hole 29 is formed in a position at each of the opposite ends of the covering 23.
  • Each weight portion 25 is configured with the weight 30 attached detachably to the holding hole 29.
  • Various types of weights 30 having different weights are prepared.
  • a weight 30 of an arbitrary weight is selected according to a training level requested by the user, for example, and attached detachably to the holding hole 29.
  • the facial muscle training tool 21 of the present embodiment is accompanied by a cover 51 that constitutes a facial muscle training tool set together with the facial muscle training tool 21.
  • the cover 51 is made of transparent or semi-transparent synthetic plastic such as polypropylene plastic, polyethylene plastic, or polyamide plastic.
  • the cover 51 has two halves including a cover piece 53 and a cover piece 54, via an integral hinge 52 at the center.
  • One of the cover pieces 53 and 54 forms a body and the other forms a lid.
  • the cover piece 53 on the lower side of Fig. 15 is the body and the cover piece 54 on the upper side of Fig. 15 is the lid.
  • Both the cover pieces 53 and 54 are formed in a concave shape to form accommodation space 511 between the cover pieces 53 and 54.
  • the orally held portion 24 and the central portion of the covering 23 of the facial muscle training tool 21 are accommodated in the accommodation space 511 and covered by the cover 51.
  • the one cover piece 53 has a latching pawl 55 and the other cover piece 54 has a receiving portion 56 to which the latching pawl 55 is to be fitted. If the cover pieces 53 and 54 are closed, the latching pawl 55 and the receiving portion 56 are fitted to hold the cover 51 in a closed position.
  • Concave portions 58 are formed in the respective side walls of the cover pieces 53 and 54. When the cover pieces 53 and 54 are closed, the concave portions 58 form openings 59 for letting the arms 31 pass through while preventing interference with the arms 31.
  • a gap 60 is formed between a marginal portion of each opening 59 and the outer peripheral surface of the corresponding arm 31.
  • the marginal portion of the opening 59 may be formed into an arc in cross section.
  • the opening 59 may be increased in thickness at the marginal portion or may be increased in thickness and formed into an arc in cross section at the marginal portion. In this way, the occurrence of a scratch or a scar in the arm 31 can be prevented.
  • the cover 51 is attached to the central portion of the facial muscle training tool 21 to cover the orally held portion 24. This can maintain the cleanliness of the orally held portion 24 to be held with lips. Further, the shape of the cover 51 substantially conforms to the outer surface of the mouthpiece 28. Thus, the facial muscle training tool 21 to which the cover 51 is attached can be housed in a dedicated case for carrying or storage.
  • the cover 51 is detached.
  • a mouthpiece 28 having necessary outer dimensions conforming for example to a training level requested by the user of the facial muscle training tool 21 is attached in advance to the core 27.
  • the weight 30 of a required weight is attached to the holding hole 29 in each weight portion 25.
  • the user puts the depression 282 of the orally held portion 24 between lips and swings his or her face up and down.
  • the weight portions 25 are vibrated up and down in resonance through the elastic plate 22 made of the plate spring. This vibration is transmitted to the orally held portion 24.
  • a load is applied to facial muscles through the lips to train the facial muscles.
  • the orally held portion 24 protrudes from a side of the arms 31 to be located in a position displaced outwardly from this side.
  • the facial muscle training tool 21 is held with the lips in a cantilever style to increase the weight to be bored on the lips.
  • the load resulting from the resonance vibration acts efficiently as the load on the facial muscles to train the facial muscles effectively.
  • the mouthpiece 28 can be held while the mouth is opened widely. Holding the mouthpiece 28 with the mouth opened widely allows the load resulting from the resonance vibration to be transmitted to the entire orbicularis oris muscle.
  • the orbicularis oris muscle is connected to muscles of facial expression such as the risorius muscle. This allows training of the risorius muscle and the like through the orbicularis oris muscle to allow efficient training.
  • the elastic plate 22 is molded using the covering 23 made of synthetic plastic.
  • the covering 23 made of synthetic plastic.
  • motions such as distortion or subtle vibration of the elastic plate 22 can be suppressed.
  • distracting motions are less likely to be transmitted to the lips of the user, so that the facial muscle training tool 21 can be used comfortably.
  • a plate or a sheet of synthetic plastic may be fixed for example with an adhesive to both or one of the front and back surfaces of the elastic plate 22.
  • the mouthpiece 28 has rubber properties of not being slippery and having proper hardness. Thus, the mouthpiece 28 is easy to hold orally and can be used for transmitting a load resulting from the vibration of the arms 31 to the lips. If the mouthpiece 28 is too hard, the mouthpiece 28 does not conform to the lips and is hard to hold orally. Conversely, if the mouthpiece 28 is too soft, even with the mouthpiece 28 held orally, the facial muscle training tool 21 cannot easily be maintained stably. Additionally, the mouthpiece 28 absorbs vibration of the arms 31 to reduce a load for training.
  • the mouthpiece 28 on the core 27 is changed to a different mouthpiece 28 of a different outer shape and the like. By doing so, one facial muscle training tool 21 can be shared between users having different mouth sizes or different mouth shapes.
  • the weight 30 in the holding hole 29 of the weight portion 25 can be changed to a different weight 30 of a different weight according to the strength of facial muscles or a training level.
  • the mouthpiece 28 is detached from the core 27, if necessary, and can be cleaned.
  • the cleaned mouthpiece 28 is attached to the core 27 again. This can maintain the cleanliness of the mouthpiece 28 and works advantageously in terms of a hygienic aspect.
  • the cover 51 is attached to the training tool 21 so as to cover the mouthpiece 28.
  • the cleanliness of the mouthpiece 28 can be maintained during carrying or storage of the training tool 21.
  • the cleanliness of the mouthpiece 28 can be maintained during carrying or storage of the mouthpiece 28.
  • a method of manufacturing the facial muscle training tool 21 of the present embodiment will be described below.
  • the core 27 is formed by injection molding at the central portion of the elastic plate 22 shown in Fig. 7 using the elastic plate 22 as an insert.
  • the bushings 26 are fitted in the two through holes 222 formed in positions near the opposite ends of the elastic plate 22. As a result, the bushings 26 protrude from both the front and back surfaces of the elastic plate 22.
  • the elastic plate 22 is placed in a molding die 101 and synthetic plastic to become the covering 23 is injected into the die 101.
  • the pressure of the injection does not act uniformly on the elastic plate 22 but it temporarily acts non-uniformly on the elastic plate 22.
  • the elastic plate 22 is curved to cause risk such as an abrasion on a molding surface of a cavity 102 of the molding die 101 due to a sharp edge at the curved end of the elastic plate 22, for example.
  • the bushing 26 abuts on the molding surface of the cavity to prevent abutting contact of the elastic plate 22 with the molding surface.
  • the facial muscle training tool 21 of the present embodiment if the orally held portion 24 is held with the lips and shaken up and down, the arms 31 vibrate in resonance while warping.
  • the length of each arm 31, the weight of the weight portion 25, the modulus of elasticity, spring constant and the like of the arms 31 including the elastic plate 22 are set such that the arms 31 vibrate in resonance if the orally held portion 24 vibrates at a frequency of less than 6.50 hertz (Hz). This allows the user to hold the orally held portion 24 with the lips to vibrate the arms 31 in resonance and to do training effectively using a resultant load.
  • the rate of downward warpage of each arm 31 in a resting state is set to exceed 4.8 percent (%) relative to the length b of each arm 31 shown in Fig. 17 .
  • the arms 31 vibrate while warping properly in response to vertical vibration of the orally held portion 24.
  • the rate of warpage is 4.8% or less, specifically, if then arms ae rigid and hard to warp, the arms are hard to vibrate in resonance. In this case, it is difficult to achieve beneficial training effect.
  • the load to be applied to the orally held portion 24 in response to resonance vibration acting on the arms 31 is set to less than 7.4 newtons (N).
  • N 7.4 newtons
  • elastic plates 22 having three thicknesses were prepared including 0.6 millimeters (mm), 0.8 mm, and 1.0 mm. Further, elastic plates 22 having seven lengths were prepared including 300 mm, 400 mm, 500 mm, 600 mm, 700 mm, 800 mm, and 1000 mm. Thus, 21 types of elastic plates 22 were prepared in total. Further, weights having five weights were prepared including 6.0 grams (g), 11.5 g, 23.5 g, 48.0 g, and 92.0 g. These weights were attached to the opposite ends of the aforementioned 21 types of elastic plates 22 to prepare 105 types of samples 120 (see Fig. 20B ). As shown in Fig.

  • These samples 120 were tested by 10 test subjects using their feelings. As shown in Table 2, results thereof were graded into four ranks. These four ranks are based on results of the following determinations made by six or more test subjects: being unable to generate resonance vibration (rank 4); generating resonance vibration is not easy (rank 3); generating resonance vibration is easy (rank 2); and generating resonance vibration is particularly easy (rank 1).

  • elastic plates 22 having three thicknesses namely 0.6 mm, 0.8 mm, and 1.0 mm, were prepared. Further, the elastic plates 22 were prepared that had six total lengths, namely 400 mm, 500 mm, 600 mm, 700 mm, 800 mm, and 1000 mm. Thus, 18 types of elastic plates 22 were prepared in total. Further, weights having five weights, namely 6.0 g, 11.5 g, 23.5 g, 48.0 g, and 92.0 g, were prepared.

Resonance vibration can be generated easily if the warpage rate is from 8.3 to 60.8%. Resonance vibration can be generated easily if the warpage rate is from 8.3 to 15.0% and 60.8%. Resonance vibration can be generated particularly easily if the warpage rate is from 15.2 to 48.8%. As described above, resonance vibration can be generated easily if the warpage rate is 60.8%. However, if the warpage rate largely exceeds this numerical value of 60.8%, the motion of the mouthpiece 41 is difficult to transmit to the elastic plate 22. In this case, generating resonance vibration is assumed to be difficult.

  • the facial muscle training tool 21 used for the examination was configured with the body of the facial muscle training tool 21 excluding the weight 30, specifically formed of the elastic plate 22, the covering 23, the core 27, and the mouthpiece 28.
  • the body had a weight of 120 g and a total length of 540 mm.
  • the elastic plate 22 had a length of 380 mm and a thickness of 0.6 mm.
  • the weight of the weight 30 was any of 18 g, 23 g, and 28 g. Photographs of the faces of the test subjects were taken before the examination test, that is, before use of the facial muscle training tool 21, and after the examination test, that is, after use of the facial muscle training tool 21. These photographic images were examined using the software "Mirror" for two-dimensional skin surface analysis, which is a trademark of Canfield Scientific Inc., U.S.A., to measure the changes between before and after the examination test. Results of the measurement are shown graphically.
  • Figs. 21A, 21B , and 22 show examination on the lift of the corners of mouths of the test subjects.
  • a distance 106 between the corner of the mouth and the corner of an eye of each of the 67 test subjects was measured in a photograph taken before use and a photograph taken after use. Then, change in the distance 106 between before and after use was calculated. Calculation results of the 67 test subjects obtained before use and those obtained after use were averaged and are shown graphically in Fig. 22 .
  • the distances 106 were reduced about 0.6 mm on average compared to the distances 106 before use, which shows lift of the corners of mouths. Thus, the training effect was recognized.
  • Figs. 23A, 23B, and 24 show examination on the lift of cheeks.
  • a horizontal line 107 passing through the intertragic notch of the ear and a horizontal line 108 passing through the corner of the mouth were set.
  • a longest length point 110 on the contour at the cheek, measured from the intertragic notch as the origin 109, was determined between the horizontal lines 107 and 108.
  • the distance between the origin 109 and the longest length point 110 was measured in a state before use and in a state after use.
  • Nine test subjects whose intertragic notches or contours at cheeks could not be identified clearly were excluded from the examination. Data pieces about the 58 test subjects were averaged.
  • Figs. 25A, 25B, and 26 show examination on face line firming effect.
  • a horizontal line 111 passing through the base of the wings of the nose was set, and a contour 112 of the face below the horizontal line 111 was set.
  • the area between the horizontal line 111 and the contour 112 was calculated in a state before use and a state after use. Changes between before and after use were calculated are graphically shown in Fig. 26 .
  • using the facial muscle training tool 21 reduces dimensions of every part of a face, so that it is assumed to achieve rejuvenating effects.
  • the weight 30 of the first embodiment is omitted.
  • a large-area portion 122 is formed at each of the opposite end portions of the elastic plate 22.
  • the large-area portion 122 functions to apply a load instead of the weight 30.
  • this structure preferably includes a through hole 222 and a bushing 26, and the bushing 26 is preferably provided at the tip of the large-area portion 122.
  • the parts count is reduced to achieve a simplified structure.
  • a large-area portion 122 made of the covering 23 is formed at each of the opposite end portions of the covering 23.
  • the elastic plate 22 is formed into such a length that the elastic plate 22 reaches a central portion of the large-area portion 122.
  • the elastic plate 22 is formed such that its dimensions in thickness and width are gradually reduced from the central portion toward the tip of the elastic plate 22 in its longitudinal direction.
  • a weight piece 330 made of a metal plate is embedded in each of the opposite ends of the facial muscle training tool at the large-area portion 122.
  • the weight piece 330 has one first passage hole 331 and a pair of second passage holes 332.
  • the second passage holes 332 are located in the covering 23.
  • the synthetic plastic forming the covering 23 enters the second passage holes 332 to ensure strength of coupling between the weight piece 330 and the covering 23.
  • the weight piece 330 has a notch 333 formed in both the front and back surfaces thereof and at each of the opposite ends of the covering 23.
  • the first passage hole 331 is located in the notch 333.
  • An ornamental clip 334 made of synthetic plastic is fitted in the notch 333.
  • the ornamental clip 334 is tinted in a color different from the color of the covering 23. Further, the outer surface of the ornamental clip 334 is continuous with the outer surface of the covering 23.
