(1) Structure of the slide base 4 and the tilting plate 6 etc. FIGS. The base 1 is a rectangular wood or resin plate. On the surface of the base 1, two parallel metal or resin slide grooves 2, 2 ( (Regulatory mechanism) is formed. Stops 3 are formed at both ends of the slide grooves 2 and 2 without penetrating to the edge of the base 1.

  A rectangular wood or resin plate-like slide table 4 (slide body, slide tilt body) is placed on the base 1, and four roller wheels 5 ( A restriction mechanism is attached. The distance between the four roller wheels 5 in the width direction of the slide table 4 is equal to the distance between the slide grooves 2 and 2, and the four roller wheels 5 rotate in the slide grooves 2 and 2 of the base 1. It can be moved back and forth.

  The base 1 is placed on a floor or the like substantially along a horizontal plane, so that the slide base 4 is reciprocated in a substantially horizontal direction. Further, since the four roller wheels 5 are regulated so as to reciprocate only in the slide grooves 2, 2, the direction of reciprocation of the slide base 4 is regulated only in one direction.

  Since the stoppers 3 are formed at both ends of the slide grooves 2 and 2, the slide table 4 does not protrude from the base 1. The lengths of the base 1 and the slide grooves 2 and 2 are about 1 m to 2 m, which is longer than a change when a person with a large height flexes and stretches the lower leg. On the base 1, a buttocks of a person who performs complete lower limbs may be placed.

  A rectangular plate-like wood or resin tilting plate 6 (tilting body, sliding tilting body) of approximately the same size as the slide table 4 is erected and attached via a hinge 7 at substantially the center of the slide table 4. ing. By this hinge 7, the tilting plate 6 can be rotated with respect to the slide table 4 along the reciprocating direction of the slide table 4 to change its direction.

(2) Structure of the footrest part 12 etc. FIG.2 and FIG.3 shows the footrest part 12 grade | etc.,. A long hole 11 is penetrated below the center of the tilting plate 6, and the long hole 11 is elongated along the longitudinal direction of the tilting plate 6 and the reciprocating direction of the slide base 4. A footrest 12 made of resin or the like is attached to one surface of the tilting plate 6, and the back of one foot of a person who performs leg improvement is in contact with the footrest 12.

  The footrest portion 12 has a shape of a shoe sole, and the heel portion extends along the side surface of the foot so that the edge of the shoe sole extends to form an extension portion 13, and wraps the entire heel. Moreover, the heel does not directly contact the upper surface of the slide table 4, and the heel is prevented from rubbing on the upper surface of the slide table 4.

  Here, the “heel” refers to the lower surface portion of the foot corresponding to the tarsal bone of the three parts of the human foot bone, the metatarsal bone, and the tarsal bone, and the side surface portion connected thereto. Note that “arch” refers to the lower surface portion of the foot that hits the five metatarsals and the side portion connected to it, and “toe” refers to the lower surface portion of the foot that hits the five phalanges, and the side surface portion and the upper surface portion connected thereto. .

  A hole is formed in the center of the heel portion of the footrest portion 12, and a bolt 14 is inserted from the hole to the elongated hole 11. A washer and a nut 15 are screwed onto the tip of the bolt 14, and the footrest The part 12 is attached so as not to be detached from the tilting plate 6.

  The bolt 14 and the nut 15 are slidable in the elongated hole 11, and as a result, the footrest portion 12 is centered on the foot along the direction connecting the toe and the heel of the foot with respect to the tilting plate 6. It is attached so that it can reciprocate along a linear direction or along the centerline direction of the footrest part 12. FIG.

  This makes it possible to absorb changes in the front and back or up and down directions of the legs, ankles, knees, hips and the like each time the lower limbs are bent and extended, and to prevent them from being subjected to excessive force. The length of the long hole 11 is several cm or 5 to 10 cm, and the tilting plate 6 is allowed to change between 5 degrees and 120 degrees, preferably 20 degrees to 100 degrees with respect to the slide table 4. ing.

  In addition, the length of the elongated hole 11 is determined with a margin so that the extended portion 13 of the footrest portion 12 can always come into contact with the upper surface of the slide base 4 in the change of the angle, and the foot is moved with respect to the tilting plate 6. This section 12 can reciprocate with a margin.

  Therefore, while the tilting plate 6 changes its direction with respect to the slide table 4 substantially along the reciprocating direction of the slide table 4, the extended portion 13 at the end of the footrest 12 is connected to the slide table 4. It will always be in contact.

  Further, since the footrest portion 12 is attached to the tilting plate 6 only at one position of the bolt 14 and the nut 15, the footrest portion 12 is configured with the bolt 14 and the nut 15 as the rotational axis / rotation center. Is rotatable with respect to the tilting plate 6.

  Since the positions of the bolts 14 and the nuts 15 are the center of the heel and the center of the lower leg, the footrest 12 can be rotated with respect to the tilting plate 6 around these. This makes it possible to absorb changes in the left and right orientations of the legs, ankles, knees, hips, and the like each time the lower limbs are bent and extended, and to prevent excessive force from being applied thereto.

  A portion of the upper surface of the slide table 4 where the extended portion 13 of the footrest portion 12 hits is recessed to form a contact portion 16. The extended portion 13 is not polished by the contact portion 16, and the upper surface of the slide table 4 is not polished.

  The edge surface of the tilting plate 6 with the hinge 7 is not at right angles to the front surface or the back surface of the tilting plate 6 but is about 60 to 80 degrees. Thereby, the angle when the tilting plate 6 stands with respect to the slide table 4 described above is allowed to change between 120 degrees and 100 degrees. This angle may be 30 to 90 degrees, or 45 to 85 degrees.

  The front end of the bolt 14 and the nut 15 protrude from the back surface of the tilting plate 6. Since the protruding tip of the bolt 14 and the nut 15 abut on the upper surface of the slide table 4, the back surface of the tilting plate 6 does not overlap the upper surface of the slide table 4 and maintains a constant inclination. This prevents the toe on the footrest 12 from being extended more than necessary, or the toe does not float from the tip of the footrest 12, and the effect of improving the lower limbs is not reduced.

  The angle when the tilting plate 6 is tilted with respect to the slide table 4 is 5 to 20 degrees. This angle may be 5 to 30 degrees, or 5 to 40 degrees. The minimum angle of the tilting plate 6 with respect to the slide table 4 may be 0 degrees instead of 5 degrees. In this case, the long hole 11 may be formed in a two-step shape, and the tip of the bolt 14 and the nut 15 may be accommodated in the step.
