It should be noted that the embodiments of the constituent elements of the present invention are not limited to the following embodiments, and can take various forms as long as they fall within the technical scope of the present invention. In the figure, U means upward direction and D means downward direction.

The main components of the ankle and toe exercising device 1 according to the present invention are a housing 10, a footrest plate 20, a flat plate 30, a bar member 40 and a driving mechanism 50. As shown in FIG. Each component will be described in detail below.

As shown in FIGS. 1 and 2, the housing 10 is composed of a bottom plate 12 which is a rectangular plate material and a box 13 having an open bottom surface. be done.

A swing shaft 21 is laid across the front side plate and the rear side plate of the housing 10 . A footrest plate 20 is attached to the swing shaft 21 so as to be swingable.

A cushion material 14 is attached to a portion of the top surface 11 of the housing 10 that the user's heel hits.

A long hole 15 is provided in the top surface 11 of the housing 10 so that the top surface 11 does not become an obstacle when the mounting plate 20 swings.

The footrest plate 20 is a substantially square plate material, and as shown in FIGS. 6 and 7, a pair of projecting portions 23, 23 are provided above the left and right ends thereof. A flat plate 30 is fitted between the pair of projections 23, 23 so as to be swingable around a swing shaft 31. As shown in FIG.

As shown in FIG. 6, a belt 22 is attached to the footrest plate 20 over its left and right ends. Crossing belts 32 are also attached to the flat plate 30 near its left and right ends.

A driving mechanism 50 is installed on the bottom plate 12 that constitutes the housing 10 .

The driving mechanism 50 drives the rack 51 so as to be movable in the horizontal direction in FIG. Note that the tooth portion of the rack 51 is present at a portion located inside the casing 52 . A pinion meshing with the rack 51 is present in the casing 52. The pinion is connected to the drive shaft of the motor in the casing 52, and is therefore driven to rotate in forward and reverse directions by the drive shaft. It is a thing.

As shown in FIG. 1 and the like, the rack 51 is fixed with a rod 53 having an engaging portion 54 at its upper end that is engaged with the lower portion of the footrest plate 20 . The locking portion 54 is a plate member curved in an arc shape. As shown in FIG. 4, when the rack 51 moves leftward, the upper edge of the locking portion 54 is locked to the lower end of the footrest plate 20, and the footrest plate 20 swings in the A direction. As shown in FIG. 5, when the rack 51 moves rightward, the lower edge of the locking portion 54 is locked to the lower end of the footrest plate 20, and the footrest plate 20 swings in the B direction.

The drive mechanism described above is an example. A disk-shaped gear provided in the mesh may be meshed. Alternatively, a drive mechanism may be used in which the footrest plate 20 is fixed and connected directly to the drive shaft of the motor. A flexible bar member 40 is provided.

The rod member 40 is composed of a tubular body 41 and a rod body 42 . The rod 42 is provided so as to slide in and out of the hollow portion of the cylindrical body 41 . As a result, the bar member 40 can be expanded and contracted. The reason why the rod member 40 is telescopic is that the flat plate 30 cannot swing unless it is telescopic.

A lower end portion 41a of the cylindrical body 41 is ring-shaped. As shown in FIGS. 3 to 5, a gate-shaped shaft 11a provided on the top surface 11 is loosely inserted into the ring-shaped portion of the lower end portion 41a. Due to such a structure, the cylindrical body 41 can freely swing about the shaft 11a.

An upper end portion 42a of the rod 42 is ring-shaped. As shown in FIGS. 3 to 5, a gate-shaped shaft 30a provided on the flat plate 30 is loosely inserted into the ring-shaped portion of the upper end portion 42a. Due to this structure, the rod body 42 can freely swing about the shaft 30a.

As shown in FIG. 4, a donut-shaped flange 41b is provided on the peripheral surface of the hollow portion of the tubular portion 41, and a disk-shaped flange 41c is provided below the hollow portion of the tubular portion 41. is provided. On the other hand, the lower end of the rod 42 is provided with a disk-shaped bottom portion 42b. The bottom 42b of the rod 42 is movable between the flanges 41b and 41c.

The reason for this structure is that, as shown in FIG. 4, the bottom portion 42b abuts against the flange portion 41b so that the rod 42 cannot extend upward any more, thereby allowing the flat plate 30 to move upward. This is for swinging in the B direction. Similarly, as shown in FIG. 5, the bottom portion 42b abuts against the flange portion 41c to prevent the rod 42 from extending further downward, thereby swinging the flat plate 30 in the direction A in the drawing. to move it.

In FIGS. 4 and 5, the portions of the rod 42 that are inside the cylindrical body 41, the flange 41b, the flange 41c, and the bottom 42b are not visible. It is drawn with a solid line for the sake of simplicity.

The ankle and toe exercising device 1 shown in each figure swings only the foot and toes of one side, but the housing 10 has a wide width and the configuration of the present invention other than the housing 10 By arranging two members side by side, it is possible to perform bending and stretching exercises for both legs at the same time.
