With these two connecting arms 14, 14, the movable plate 12 is placed on the abutting portions 13t of the four guide posts 13 above the base 11, and is guided by these guide posts 13 to move up and down. Parallel movement becomes possible.

FIG. 3 is an explanatory side view showing a state in which the movable plate is placed above the base in the embodiment shown in FIG. 2, omitting the illustration of the guide posts.
FIG. 4 is an enlarged view of a main portion of FIG. 3, and is an explanatory view illustrating the relationship between the eccentric cam and the rotating wheel.

These two figures will explain the operation of the heel dropper according to the present invention.
First, the power is turned on to the electric motor 20, which is a rotation driving machine.
When the electric motor 20 is powered on, the rotation shaft 20j of the electric motor 20 also rotates, and the rotation direction is changed by 90 degrees by the gear box 30, which is a power transmission unit, to rotate the rotation shaft 15j.

When the rotating shaft 15j rotates, the three eccentric cams 15 fixed thereto rotate.
The notches of all three eccentric cams 15 are arranged identically so that they can be synchronized, and vertical movement of the movable plate can be parallel movement.
3 and 4 show the state where the longest radius portion 15m of the eccentric cam 15 is in contact with the rotating wheel 16, so the movable plate 12 is positioned at the uppermost fulcrum.
As the eccentric cam 15 rotates to the right, the rotating wheel 16 drops downward at once. The reason why the rotating wheel 16 is arranged at the position of the eccentric cam 15 is that the rotating wheel 16 rolls down at once when the eccentric cam 15 rotates.

When the eccentric cam 15 continues to rotate clockwise from the state in which the rotating wheel 16 has dropped to the lowest fulcrum, the rotating wheel 16 is gradually pushed upward. As a result, the movable plate 12 gradually moves upward in parallel.

When the eccentric cam 15 reaches the positions shown in FIGS. 3 and 4, the rotating wheel 16 reaches the uppermost fulcrum, and then drops again to the lowermost fulcrum. Hereinafter, the above operation will be repeated.
In the above embodiment, four guide posts are provided. Therefore, when the abutting portion of the guide posts is arranged above the lowest fulcrum of the eccentric cam, the lowest fulcrum is the guide post. becomes the abutting part of the

Based on the above operation, the user, who is on the movable plate 12 of the heel dropper according to the present invention, places the soles of both feet on the movable plate 12 to use the movable plate 12. A parallel movement is performed up and down, and a heel dropping motion is performed particularly when falling from the highest fulcrum to the lowest fulcrum.

On the other hand, even a handicapped person sitting in a wheelchair or the like can ride on the movable plate using the auxiliary plate in the wheelchair, and then turn on the power to the electric motor. This means that the heel dropping exercise can be performed.

Although the embodiments of the present invention have been described above, various design changes are possible in the present invention.
No particular explanation was given about the switch section for turning on the power to the electric motor. or buttons for selecting other settings.

The vertical and horizontal sizes and thicknesses of the base and the movable plate can also be set as appropriate.
The height of the front handrail and the height and length of the side handrails can also be set appropriately.
The height of the guide post can be changed, and the height of the contact portion can be changed freely. These height adjustments can be automatically performed and can be operated by a switch section.

By changing the height of these guide posts, it is possible to adjust the vertical translation distance of the movable plate.
As for the eccentric cam and the rotating ring that abuts thereon, two are provided on one side edge of the base and two are provided on the other side of the base. Two pieces may be provided on the other side edge side, four pieces each in total, or more pieces may be provided freely.

The connecting arms are also provided on the back side of both side edges of the movable plate. By adopting the configuration, it can be implemented without providing a connecting arm.
The point is that the positions of the eccentric cam and the rotating ring should match and they should be able to move in parallel.

Also, the size of the eccentric cam and the size of the rotating ring can be freely designed.
Although the base and the movable plate are made of wood in the above embodiment, they can be made of other materials such as synthetic resin or metal.
As for the handrail, we used a metal tubular body, but other materials can be freely selected.

As described above, in the present invention, it is possible to provide an automatic machine that realizes the heel drop exercise, which can be easily used by an elderly person or a handicapped person sitting on a wheelchair. It was possible to provide a heel dropper which is a very convenient health device that facilitates heel drop exercise.
