Description

  The present invention relates to a stretch board for stretching or massaging a sole, an arch or a calf, or performing a toe exercise.

  The foot is the only body that touches the ground and supports the body, and has a function of inducing movement of the body. The human body is a standard body that forms a skeleton with 208 bones. Among them, the bones of the legs are composed of 26 legs on one leg and 52 legs on both legs, excluding the legs. It accounts for one part.

  The foot includes a foot part (front foot part, middle foot part, rear foot part) and an ankle joint, and the foot part and the ankle joint are connected by 20 or more ligaments in large and small, and these are moved by muscles. In this way, it has a function to support an upright body and a motor function such as walking.

  A person is not in contact with the ground with two legs (two points), but stands on three points on the sole of the foot, a total of six points, to support the body. That is, the foot has three points: the first metatarsal bone near the ribs and the big toe and the fifth metatarsal bone near the toes, and the inner arch from the ribs to the first metatarsal, Three foot arches (archs) of the front arch are formed from the outer arch over the 5 metatarsals and from the first metatarsal to the fifth metatarsal, with the ligaments and muscles holding the curves of the sole arch , Maintain the correct posture and balance the ground properly.

  In ancient times, samurai, especially during the Sengoku period, wore a footpad (forefoot) and a sandaled shoe (length: about 13 cm), and firmly grasped the ground with the footpad. There is a history of fighting by efficiently inducing movement.

  However, in modern times, the function of the forefoot is often ignored, and high heels place great importance on aesthetics, and the tip is so thin that the toes from the thumb to the little finger are deformed to form a hallux valgus. Also, because of the high heels, it affects the whole body such as lower limbs and pelvis to balance upright position. In addition to this, recently, it has become a highly cushioning shoe to ease the impact of the sole, ignoring the function of supporting the body with three sole arches, mimicking the result of promoting flat feet .

  Conventionally, for the health of the sole, various stretch devices have been proposed as proposed in Patent Documents 1 to 6.

  Various proposals have been made on these stretching devices, such as those that stimulate the soles like a bamboo bamboo stepping, and those that balance the posture while adjusting the inclination of the footrest to widen the range of motion of the ankle joint.

  However, stimulating the sole, such as a bamboo footstep, has a certain effect, but if it is performed excessively, it directly compresses the nerves and blood vessels that pass through the sole, which is counterproductive. In addition, flat feet are caused by ligaments and muscles that form arches and muscle weakness and weak muscle strength. Even if you forcibly form arches and stretch by stepping on bamboo, you cannot expect much effect in correcting flat feet. Furthermore, it is not expected to maintain the soundness of the sole arch, although there is an effect of improving the flexibility of the ankle joint by inclining the footrest.

  As mentioned above, there are 26 bones on one foot and 52 bones on both feet, and these bones are intricately connected by ligaments and muscles. For the treatment of hallux valgus, the front foot, especially the foot Even if the thumb is expanded and corrected, the sole arch is further broken and the reverse effect is obtained.

  Thus, it is important that three sole arches are maintained and formed in a healthy manner on the soles. Restoring the soundness of the sole arches can correct flat feet, hallux valgus, etc. and posture correction. However, in the past, the presence or absence of the arch has been studied, but the soundness of the three sole arches is not considered at all.

  Accordingly, an object of the present invention is to provide a stretch board capable of solving the above-described problems and recovering the soundness of the sole arch.

  In order to achieve the above object, the present invention includes a footboard on which a footrest portion on which a foot is placed is formed, and a ventboard that is slidably engaged with the footboard and adjusts the inclination angle of the footrest portion. The stretch board is characterized in that a toe bar is formed near the top of the step platform.

  The footboard is preferably composed of a support plate and an elastic sheet to be affixed on the support plate, and the toe bar is preferably formed integrally with the elastic sheet.

  The toe bar is formed near the top of the step portion of the elastic sheet, has a concave groove in the center, and is formed of a protrusion on a semi-cylinder having a height of 10 to 20 mm in the left-right direction from the concave groove. It is preferable.

  It is preferable that the protrusions of the toe bar are formed so that the width thereof is gradually reduced in the left-right direction from the concave groove side at the center.

  It is preferable that the protruding body is formed to be inclined 7 to 10 degrees rearward from the concave groove at the center.

  It is preferable that a large number of micro cylindrical projections are formed on the surface of the elastic sheet.

  The present invention provides a toe bar near the top of the footboard of the foot boat with adjustable tilt angle. By using this toe bar, exercise of towel gathering movement of the toes and stretching of the foot arch is possible. It demonstrates the excellent effect of effectively strengthening the ligaments and muscles of the sole arch.

It is the whole stretch boat perspective view of the present invention. It is a top view of FIG. It is a bottom view of FIG. FIG. 4 is a waist cross-sectional view showing details of the connecting portion in FIG. 3. FIG. 2 is a front view of FIG. 1, in which (a) shows a state in which the tread is inclined by 16 degrees, (b) shows a state in which it is inclined by 23 degrees, and (c) shows a state in which it is inclined by 30 degrees.

  Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  1 to 5, a stretch boat 10 of the present invention includes a foot board 11 on which a foot is placed, a vent board 12 that is slidably engaged with the foot board 11 and adjusts an inclination angle of the foot board 11, After adjusting the angle of the footboard 11, it is basically composed of an angle adjusting and fixing means 13 for fixing the vent board 12 to the foot board 11.

  The footboard 11 includes a support plate 14 made of a synthetic resin and an elastic sheet 15 such as a synthetic rubber attached on the support plate 14, and further includes a support plate 14 and an elastic sheet 15 with a rear side on the floor side. A step 11a that is in contact with the surface F and is inclined upwardly from the floor F is formed, and a curved surface portion 11b having a circular arc shape that is continuous from the top 11c of the step 11a is formed.

  In order to prevent deformation of the support plate 14 on the back surface of the support plate 14, a reinforcement frame 16 formed in a steel beam shape is provided, and the rear end of the reinforcement frame 16 in contact with the floor F is Rubber pads 17 and 17 are respectively provided (see FIG. 3).

  The bent board 12 is formed of the same synthetic resin as the support plate 14, and has a curved surface portion 12b formed with the same curvature as the back surface of the support plate 14 of the curved surface portion 11b, and extends from the curved surface portion 12b so as to incline forward. It is formed by a front edge portion 12a in contact with F.

  Both sides of the curved surface portion 12b of the vent board 12 are fitted into U-shaped guides 18 provided on the reinforcing frame 16 so that the vent board 12 and the support plate 14 can move slidably. A concave portion 19 is formed at the center of the curved surface portion 11b of the support plate 14, and a concave portion 20 is formed on the curved surface portion 12b of the vent boat 12 so as to fit the convex portion on the back surface of the support plate 14 formed by the concave portion 19. It is formed so as to further guide the sliding of the board 12 and the support plate 14.

  The concave portion 19 formed in the center of the curved surface portion 11b of the support plate 14 receives the spine that is convex from the back when the stretch boat 10 is used for stretching the spine, so that the entire back is uniformly formed on the elastic sheet 15. There is also a hitting action.

  Rubber pads 21 and 21 are provided on the back surface of the front edge portion 12a of the vent board 12 in contact with the floor surface F (see FIG. 3).

  As shown in FIGS. 3 and 4, the angle adjusting / fixing means 13 is arranged so that the screw 22 penetrates the screw 22 provided to project from the back surface of the support plate 14 and the curved surface portion 12 b of the vent boat 12. The formed long groove 23 and the curved surface portion 12b of the bent boat 12 are provided to cover the periphery of the long groove 23 and the same long groove 24 as the long groove 23 is formed, and the floor surface F of the step 11a of the footboard 11 is formed in the long groove 24. A metal guide plate 26 formed with a latch hole 25 for holding the angle with respect to three positions of low, medium, and high (16 degrees, 23 degrees, and 30 degrees), and screwed into the screw 22 and the metal guide plate 26 The angle adjustment knob 28 is formed with a latch protrusion 27 that fits into the latch hole 25.

  The sliding and angle adjustment of the foot boat 11 and the vent board 12 by the angle adjusting / fixing means 13 is performed by turning and loosening the angle adjusting knob 28 screwed into the screw 22 so that the curved surface portion 12b of the vent board 12 is moved to the foot boat 11. When the screw 22 is positioned in the latch hole 25 and the angle adjustment knob 28 is tightened, the latch protrusion 27 engages with the latch hole 25 to slide. In this state, the angle adjustment knob 28 is further screwed to fix the curved surface portion 12b of the vent board 12 and the curved surface portion 11b of the foot boat 11.

  The curved surface portion 12b of the vent board 12 is provided with an angle memory 29 for confirming the low / medium / high angular positions.

  Now, the toe bar 30 is integrally formed on the elastic sheet 15 of the footrest part 11a of the footboard 11 so as to be located near the top part 11c. The toe bar 30 has a groove 31 formed in the center, and is formed of a semi-cylindrical protrusion 32 having a height of 10 to 20 mm in the left-right direction from the groove 31. It is formed so as to incline 7 to 10 degrees backward from the concave groove 31 in the center. Since the protrusion 32 is on the toe side and the left and right ends are on the toes, the toe side is thick (for example, 20 to 25 mm) and high in height (for example, 15 to 20 mm). The little finger side is formed with a narrow width (for example, 20 to 15 mm and a low height (15 to 10 mm)).

  In addition, on the surface of the elastic sheet 15, a large number of minute cylindrical protrusions 33 are formed for preventing slipping and stimulating the soles.

  Next, training using the stretch board of the present embodiment will be described.

  First, as shown in FIG. 5, the angle of the step 11a of the footboard 11 is 16 degrees shown in FIG. 5 (a), 23 degrees shown in FIG. 5 (b), and FIG. 5 (c). The angle adjustment / fixing means 13 is adjusted to any one of 30 degrees.

  After adjusting to the desired angle, the foot calf 11 can be placed upright on the toes 11a of the footboard 11 with the toes placed on the toe bar 30 as shown in FIG. 5 (a). You can stretch. At this time, by putting the toes on the toe bar 30, the weight is applied to the base of the heel and toes (inner tarsal globules), and together with the calf stretch, the inner arch, outer arch, and front arch 3 While stimulating the sole arches, the ligaments and muscles that hold these arches can be strengthened.

  In this state, the so-called goo choki par (holding the toes (rock), widening the toes), grabbing and releasing the toe bar 30 with the toes, grabbing and releasing from the toes to the little toes ( paper) ・ Janken exercises and towel gathering exercises (scissors) that open and move the toes and other toes separately (gripping towels on the floor, grabbing this towel with the toes and folding them in gathers) The muscles that move these can be strengthened.

  In addition, by placing the center of the arch (inner arch, outer arch) on the toe bar 30 and performing the stepping exercise, you can moderately stimulate the foot sole, massage and correct the arch, and either the left or right side The front arch can be stretched and corrected by stepping on the inner tarsal sphere so as to straddle the groove 31 and the ridge 32 of the toe bar 30.

  In addition, while sitting on a chair, exercise the muscles of each part of the foot by placing the foot on the stepping platform 11a so as to straddle the toe bar 30 and grasping or releasing the toes to perform a towel gather exercise. Can strengthen these muscles and improve flat feet, hallux valgus, etc.

  In particular, the step part 11 a is formed of an elastic sheet 15, and a large number of minute cylindrical protrusions 33 are formed on the surface of the elastic sheet 15. Since the cylindrical protrusion 33 can be firmly gripped and the force when gripping the elastic sheet 15 with the minute cylindrical protrusion 33 is reliably transmitted as a toe sensation during the towel gather movement by the toes, it is more effective. Exercise the muscles of the soles.

  The stretch board 10 according to the present invention can perform a forward bending exercise while sitting on the stretch board 10 and a whole body stretch with the back facing the stretch board 10 in addition to the exercise of the foot.
