Description of the Invention: [Technical Field of the Invention] The present invention relates to a stretch mat which can be easily obtained by a part of the body. [Prior Art] For example, a stretch cushion that is bulged upward in a curved shape can stretch the spine or the waist by placing the spine or the waist on the back, thereby appropriately exerting the stretch effect. As such a stretch mat, for example, a configuration of Patent Document 1 is proposed. [Prior Art Document] [Patent Document 1] Japanese Laid-Open Utility Model No. 3034398 SUMMARY OF THE INVENTION [Problems to be Solved by the Invention] The above-described conventional stretch mat is formed by bending a spine or a waist by a corresponding curved shape thereof. Get a stretch. However, the effect of stretching is only a so-called shape effect caused by a curved shape, and the effect thereof is limited. Therefore, a stretch mat for obtaining a higher stretch effect is required. The present invention proposes a stretch mat which can easily obtain a high stretch effect. [Means for Solving the Problem] The present invention is a mat for stretching, comprising: a non-ground portion formed on the back surface by 201215353 and extending over the entire width direction; and an upper surface facing the unground portion a bulge in the longitudinal direction, a portion for resting a part of the body and extending the body; a cushion body formed by an internal space formed between the ungrounded portion and the stretched portion; configured to be disposed on the body of the cushion The inner gap, the vibrating mechanism of the vibrating stretch portion, and the stretch portion of the mat main body are formed with a valley-shaped avoiding portion that is recessed in the longitudinal direction over the entire length of the stretched portion in the center in the width direction, and two of the valley-shaped avoiding portions. On the side, a body contact portion that comes into contact with a part of the body is formed, on which an innumerable small protrusion is formed on the entire body, and vibration is applied to the body via the small protrusion. Further, since the stretch mat is usually placed on the floor or the like, it has a portion on the back surface of the mat body that contacts the floor or the like (hereinafter referred to as a ground portion). In the related configuration, by vibrating the stretch portion in a state in which a part of the body is placed, vibration is transmitted from the small protrusion to the body, and the effect of stretching the body and the vibration is simultaneously generated, and the mutual effect can be large. The amplitude increases the stretch effect. In other words, by placing a part of the body on the stretched portion, it is possible to stretch a part of the muscles or the like according to the weight of the body, and to impart stimulation to the muscles or tendons by vibration. Therefore, it is relatively easy to obtain a blood circulation improvement effect, an internal muscle culture effect, a bone correction effect, etc., particularly for a woman with a weak muscle strength or a senior person, a stiff body, etc., because the muscle or joint is not excessively painful. A higher stretch is obtained, so the usability is higher. Here, since the vibration mechanism is disposed in the gap between the ungrounded portion and the stretched portion, the vibration generated by the vibration means is easily transmitted to the stretched portion, and the -6-201215353 is easy to stabilize the vibration stretched portion. However, if it is configured such that the stretch portion is disposed above the ground portion that contacts the floor or the like, and the vibration mechanism is provided in the gap therebetween, the vibration of the vibration mechanism is reduced due to contact with the ground portion of the floor, and thus it is difficult The required vibration is stably transmitted to the stretch. In the configuration of the present invention, since the vibration mechanism is provided between the ungrounded portion and the stretched portion, the vibration of the small amplitude can be stably and accurately transmitted to the stretched portion and vibrated. Further, the stretch pad of the present invention can stretch the spine, the waist, the head and neck, etc., not only by lying on its back, but also by stretching the sole or the calf muscle by standing on its stretched portion. In this way, you can stretch various parts of the body. In the stretch mat of the present invention, the stretched portion of the mat main body has a valley-shaped avoiding portion that is recessed in the longitudinal direction at the center in the width direction, and both sides of the valley-shaped avoiding portion come into contact with a part of the body. Body contact. Regarding the constitution, if lying on the stretched portion, the gluteal avoidance portion does not directly support the vertebral bone, but supports both sides of the spine bone resting on the body contact portion. Thus, at the time of vibrating the stretch portion, the vibration does not directly stimulate the spine, so excessive load does not act on the spine. Therefore, the ridge can be stretched while reducing the load on the spine bone, whereby the high stretch effect of the present invention described above can be obtained. Also, for example, when the foot is stretched, the high stretch effect of the present invention can be obtained by placing the foot on the body contact portion. Here, the body contact portion of the stretch portion is formed with an innumerable small projections on the entire upper surface thereof. 201215353 This configuration, by placing a part of the body on the body contact portion, can stimulate a part of the body by numerous small protrusions. Moreover, since the vibration is easily transmitted to the inside of the body by the numerous small projections, the above-described stretching effect can be further enhanced. Further, as the small projection, it may be appropriately set to a slightly conical shape, a flat conical shape, a cylindrical shape, a hemispherical shape, or the like. The small protrusions are in direct contact with a part of the body, and it is therefore preferable to use a hemisphere which is configured to be less prone to excessive pain. The vibration mechanism is proposed to generate micro-vibration with an amplitude of 0.1 mm to 5 mm at the small projection. If the amplitude is less than 1 mm, the microvibration is hardly felt. However, if the amplitude is 5 mm or more, the amplitude is too large, which is almost the same as that of the conventional massager. The present invention is set to the above range by stretching the muscle in a minute unit and obtaining a stretching effect. The best amplitude for the higher stretch is 0.5mm~2mm»The frequency of this amplitude is proposed to be 50~300Hz. As a vibration mechanism for generating the above-described microvibration, a plurality of vibration motors that are electrically connected in parallel are proposed, and a power supply means for supplying electric power to the vibration motor is provided. In the present configuration, the same voltage is applied to a plurality of vibration motors. For example, even when a motor of the same specification is used, there is a tolerance between each product, and thus the number of rotations of each vibration motor is slightly different. A vibration with a slight difference in amplitude or period. Therefore, by the overlapping of these complex vibrations, a small vibration (hereinafter referred to as microvibration) of an amplitude of 0.1 mm to 5 mm is generated. By the vibration of the stretched portion by the micro-vibration, the effect by the vibration is further improved, and the effect of the present invention, which is improved in the stretch effect, is further improved. Further, the vibration is generated as irregular vibration due to a slight difference in the number of rotations between the vibration motors. By this irregular vibration, it is easy to maintain the feeling of the vibration, and a part of the body can be continuously felt in a stretched state, so that the stretching effect can be further improved. However, it is assumed that when a motor is used, since it is continuously vibrated, it is accustomed to the vibration and it is not easy to recognize the portion in the stretch. In order to cause microvibration to occur, a single vibration motor may be used. Further, since it is micro-vibration, it can stand stably above the stretched portion. Therefore, as described above, the stretch of the foot also has an advantage that a stable high effect can be obtained. In the present configuration, since the vibration motor is attached to the drive shaft of the motor, the weight is coupled to the drive shaft center by the weight. Here, it is proposed that a plurality of vibration motors are arranged in parallel in the longitudinal direction in the internal space of the mat body. The plurality of vibration motors are arranged side by side in the longitudinal direction, and the stretched portion is easily vibrated in the longitudinal direction as a whole. Therefore, the difference in the degree of vibration (vibration intensity, etc.) of the entire stretch portion can be reduced as much as possible, so that the same degree of vibration effect can be imparted to the body part placed on the stretched portion. [Effects of the Invention] As described above, the stretch mat of the present invention has a stretched portion that is undulated in a direction opposite to the ungrounded portion provided on the back surface, and an internal space between the ungrounded portion and the stretched portion. It has a vibrating mechanism and transmits vibration through a myriad of small protrusions, so that it can be stimulated by vibration while stretching a part of the body by the stretch of the -9-201215353, so that high mutual stretch can be achieved by these mutual effects. effect. Furthermore, since it does not cause excessive load on muscles or joints, and it is relatively easy to obtain an effect of improving blood circulation or inner muscles, it is more useful for those with weaker muscles or stiff bodies. Further, since the body contact portion of the stretch portion is provided with a plurality of small projections on the entire upper surface thereof, a part of the body resting on the body contact portion can be stimulated by the numerous small protrusions, and the vibration is easily transmitted to the body. Therefore, the effect of the present invention which can attain a high stretching effect is further improved. In the above-described stretch mat, the stretched portion of the mat main body includes a valley-shaped avoiding portion that is recessed in the longitudinal direction, and both sides of the mat-shaped avoidance portion serve as body contact portions, and thus are placed on the stretched portion for stretching. The ridge avoidance portion can stretch the spine without excessively stimulating the spine bone. Moreover, the vibration mechanism can be used to make the micro-vibration having an amplitude of 0.1 mm to 5 mm occur in the small protrusion, thereby giving a higher stretching effect. High stimulation. This optimum amplitude is 0.5 mm to 2 mm. When a vibration device that generates microvibration having an amplitude of 0.1 mm to 5 mm is formed by a plurality of vibration motors that are electrically connected in parallel, microvibration is likely to occur due to a tolerance between each motor. The vibration and the effect of the present invention in which the above-described high stretch effect can be obtained are further improved. Here, when the plurality of vibration motors are arranged side by side in the longitudinal direction of the cushion main body, the difference in the degree of vibration of the entire stretched portion can be made as small as possible, so that the stretch can be placed on the stretch. [Embodiment of the same part of the body part of the vibration effect] -10- 201215353 [Embodiment] [Embodiment for Carrying Out the Invention] Embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 to 4, the stretch mat 1 of the present embodiment is configured to have a stretch portion 11 which is swelled upward in an undulating manner, and is provided by a plurality of stretches provided in the inner space thereof. The power supply line 35 for supplying power to the vibration motor is connected to the external power supply 41. Further, in the present embodiment, the vertical direction in the second drawing is the wide direction, and the horizontal direction is the vertical direction. The stretch mat 1' is provided as shown in the first to sixth embodiments, and the mat main body 3 having the stretch portion 11 and the base body 4 joined to the lower side of the stretch main body 3 are integrally formed. Here, the main body 3 and the base body 4 are stretched and joined together by a plurality of screws not shown. In this embodiment, the base 4 is formed of a plastic sheet. Further, the comfort main body 3 is formed of a shell-shaped main body 3a of a plastic thin plate and a rubber cover 3b covering the upper surface of the shell-shaped main body 3a. Here, the shell-like main body 3a forms the basic shape of the stretch main body 3, and the cover 3b is formed to face the upper surface of the shell-like main body 3a. Then, the stretch main body 3 is constructed by being joined to the body by the cover member 3b on the shell-shaped main body 3a. The base 4 includes a non-ground portion 2 1 that is bent upward in the width direction thereof, and ground portions 22 and 23 that are provided on both sides in the longitudinal direction of the unground portion 21. When the base 4 is placed on the floor, the ground portions 22, 23 are placed on the floor surface, and the unground portion 21 is off the ground. Further, in the ungrounded portion 21 of the base 4, three curved ribs 26 -11 - 201215353 projecting upward are arranged in parallel in the longitudinal direction (see Fig. 5, Fig. 6). The rigidity of the unground portion 21 is increased by the curved ribs 26. The above-described stretch main body 3 includes support extending portions 12 and 13 joined to the respective ground portions 22 and 23 so as to cover the ground portions 22 and 23 of the base 4 from above; and between the support extending portions 12 and 13 The stretched portion 11 is connected. Here, the stretch portion 11 is provided to face the unground portion 21 of the base 4, and is formed in a curved shape that is undulated in the longitudinal direction. Further, the height of the swelled portion 11 raised upward is higher than the ungrounded portion 21 of the base 4. Further, side portions 15 and 15 that close the both sides are formed on both sides in the width direction of the stretch portion 11. The stretch main body 3 is formed in a box shape having a downwardly recessed lower opening according to the stretch portion 11, and the lower opening is closed by the unground portion 21 of the base 4. That is, by joining the stretch main body 3 and the base 4, an internal gap 9 is formed between the stretched portion 11 and the ungrounded portion 21 (see FIGS. 5 and 6). Inside the stretched portion 11 constituting the shell-shaped main body 3a of the stretch main body 3, a plurality of projecting ribs 16 projecting inward are formed at positions facing the curved ribs 26 of the ungrounded portion 21, and the stretched body is joined. In the state of the base body 3 and the base 4, the protruding ribs 16 and the curved ribs 26 abut. By thereby protruding the ribs 16, the rigidity of the stretched portion 11 is increased. Further, the stretched portion 11 of the stretch main body 3 is formed with a concave valley-shaped avoiding portion 18 in the longitudinal direction at the center in the width direction. Further, body contact portions 19, 19 are formed on both sides in the width direction of the valley-shaped avoiding portion 18. That is, the dilating portion 1 1 is composed of a valley-shaped avoiding portion 18 and body contacting portions 19 and 19. Here, the outer surface (upper surface) of the body contact portions 19, 19 is provided with an innumerable small projections 20 in its entirety. This small projection 20 is formed on the cover 3b constituting the outer surface of the stretch main body -12-201215353, and is elastic because it is made of rubber. Further, the support extending portion 12 of the stretch main body 3 is formed such that its outer peripheral edge portion is formed in a upwardly convex shape, and the region surrounded by the outer peripheral edge and the stretched portion 11 is slightly concave. Further, four vibration motors 31 (see FIG. 5) are disposed in the internal space 9 of the mat body 2 formed by joining the stretch main body 3 and the base 4, and the four vibration motors 3 1 are Parallel electrical connection. The vibration motor 31 is fixed to the base body 4 between the curved ribs 26 and 26 formed on the unground portion 21 of the base 4, and is arranged side by side in the longitudinal direction. The four vibration motors 3 1 are arranged linearly in the longitudinal direction. The wiring relating to the vibration motor 31 is omitted in the fifth and sixth figures. Here, the vibration motor 31 is a motor of the same specification, and the weights 33 attached to the respective drive shafts are also the same. The weight 33 is attached to the front end of the drive shaft at a position offset from the axis, and the vibration motor 31 vibrates by the rotation of the drive shaft. Further, even in the case of a motor of the same specification, there is a manufacturing tolerance, and thus a slight difference in the rotation speed or the like occurs. Therefore, even if the four vibration motors 31 are electrically connected in parallel and the same voltage is applied, the number of rotations of the respective vibration motors 31 is not completely the same. Therefore, the vibration generated by each of the vibration motors 31 has a slight difference in amplitude or period, and is mutually buffered to become an overall microvibration. The microvibration thus generated is transmitted to the stretch portion 11 of the stretch main body 3 via the unground portion 21 of the base 4, and the stretch portion 11 is vibrated. Further, this microvibration is transmitted to the stretch portion 11 via the above-described curved rib portion 26 and the projecting rib portion 16. This microvibration proposes a microvibration having an amplitude of 0.1 mm to 5 mm. In the amplitude below -13- 201215353 0.1 mra, microvibration is not felt very much. If it is 5 mm or more, the amplitude is too large and there is almost no difference from the conventional massager. The present invention stretches muscles in a minimum unit to achieve a stretching effect, so it is set to the above range. Furthermore, the optimum amplitude for the higher stretching effect is 5 mm to 2 mm. This vibration is proposed to have a frequency of 50 to 300 Hz. Further, a control board (not shown) for controlling the supply of electric power to each of the vibration motors 31 is disposed inside the side surface portion 15 of the stretch main body 3 (internal space 9). On the outer side of the side portion 15, an insertion port 36 into which the plug of the power supply line 35 can be inserted is provided, and the insertion port 36 is connected to the control substrate. Thereby, the power source obtained from the power source line 35 connected to the external power source 41 (plug) is supplied to each of the vibration motors 31» via the control board. In the present embodiment, the shell-shaped body 3a of the stretched portion 1 1 and A pressure sensor (not shown) is disposed between the cover 3b, and the pressure sensor is connected to the control substrate. The control board is configured to effectively control the supply of electric power to each of the vibration motors 31 when the pressure input from the pressure sensor is equal to or greater than a predetermined value. That is, even if the power cord 35 is connected to the external power source 41, a part of the body is placed on the stretch portion 1 1 and the stretch portion 11 does not vibrate if no weight is applied. As a result, unnecessary power consumption can be controlled. Further, a power switch (not shown) for performing a ΟΝ/OFF operation is disposed in the side surface portion 15 of the stretch portion 11 in the vicinity of the insertion port 36, and a lamp having a strong vibration is displayed, and a lamp or the like is displayed, which are connected to the above. The substrate is controlled and controlled by it. In the present embodiment, the power supply mechanism of the present invention is constituted by a control substrate (not shown) and a power supply line 35. -14- 201215353 Next, the use of the above-described stretch mat 1 will be described. The stretch mat 1 is placed on the floor, and as shown in Fig. 1, the power cord 35 is connected to the external power source 41. Then, in a state where the power switch is turned ON, for example, the back ridge is placed on the stretch portion 11 of the stretch mat 1 to be lying on its back. Thereby, the spine is stretched corresponding to the stretch portion 11. Further, since the body weight falls on the stretch portion 11, electric power is supplied to each of the vibration motors by the pressure sensor of the pressure sensor. Thereby, each of the vibration motors 31 is driven, and the generated micro-vibration is transmitted to the stretch portion 11, and the stretch portion 11 is slightly vibrated. Here, since the unground portion 21 to which the vibration motor 3 1 is attached is not in contact with the floor, the micro-vibration generated by the vibration motor 31 is easily and stably transmitted, and the curved rib portion 26 of the unground portion 21 is passed through. And the protruding rib 16 is transmitted to the stretch portion 11. Thereby, the stretch portion 11 is slightly vibrated. Thus, by the vibration of the stretch portion 11, vibration is applied to the back ridge extending in the stretch portion 11, so that the stretching effect can be improved. In particular, since the stimulation caused by the micro-vibration is applied while stretching the ridge, the blood circulation improvement effect, the internal muscle culture effect, and the bone correction effect can be effectively obtained. Furthermore, since the innumerable small protrusions 20 are formed on the body contact portions 19 and 19 of the stretched portion 11, the spine can be stimulated by the small protrusions 20 while the microvibration acts on the spine via the small protrusions 20, So it is easy to stimulate inside the body. Therefore, the aforementioned blood circulation improvement effect is further improved. Further, due to a slight difference in the number of rotations between the respective vibration motors 31, the above-described microvibration is caused to generate irregular vibration. By this irregular vibration, it is easy to maintain the sensitivity to the vibration, and the body part in the stretch can be continuously felt, -15-201215353, so that the stretching effect can be further improved. Further, since the valley-shaped avoiding portion 18 by the stretch portion π can avoid contact with the spine bone, the spine bone is not directly stimulated. Therefore, by the aforementioned microvibration, excessive load can be suppressed from acting on the backbone bone. Further, in the configuration of the present embodiment, since the rubber cover 3b is disposed on the surface of the stretch portion 11, the effect of reducing the excessive load by the elastic property is excellent. Thereby, the above stretching effect can be effectively improved. As described above, the stretch mat 1 of the present embodiment exerts a stimulus generated by vibration while stretching a part of the body, so that the stretching effect can be improved. However, although the illustration of how to stretch the spine is exemplified, it is also possible to stand on the slope of the stretched portion 11 and stretch the calf muscle while stimulating by vibration. Further, it is also possible to sit on the support extension 12 of the stretch main body 3 to stimulate the pelvis by the stretch portion 11. Further, it is also applicable to various methods of use, and the same high stretch effect can be obtained. According to the stretch mat 1 of the present embodiment, a high stretch effect can be obtained because an excessive load is not applied to muscles or joints or the like. Therefore, it is suitable for women with weak muscle strength or elderly people, or those with stiff body, and thus has the advantage of easily obtaining a higher stretching effect. In the above-described embodiment, four vibration motors are arranged in parallel. However, the vibration motor may be appropriately set to two or three or five. Further, the installation position can be appropriately set. The present invention is not limited to the above-described embodiment, and other configurations can be appropriately changed as long as they are within the scope of the invention. For example, a charging battery may be disposed inside the mat body, and the charging battery may be charged by the power cord -16-201215353.
