JPS6025271Y2 - Pedal crank type walking exercise device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The object of the present invention is to provide an exercise equipment that can provide large bending and stretching movements to the legs using a pair of pedal crank mechanisms similar to those of a bicycle.

Examples will be described below.

1' and 1# are pedals like those used on bicycles,
2' and 2'' are curved presser metal fittings for inserting and holding the toe of the foot, and both ends thereof are holding metal fittings 12 for the rubber body 11 of the pedal.
is welded to.

The pedals 1', 1'' are free to rotate about their axis of rotation 3', 3''.

Furthermore, cranks 4 and 5 are fixed to the rotating shafts 3' and 3'', which are perpendicular to the respective rotating shafts.

The crank 4 can fit and slide inside the cylinder of the crank 5.

6 is a set screw for fixing the cranks 4 and 5 to each other.

Figure 4 explains how to use it.

First, place the tool on the ground, and start by placing the tip of your left foot on pedal 1' and the tip of your right foot on pedal 1''.

First, the pedal 1'' is carried by the tip of the right foot along the dotted circular curve A in the direction of the arrow.

Next, use the tip of your left foot to carry the pedal 1' along the dotted curve opening.

In this way, the user walks by alternately moving his or her feet at crank lengths with pedal intervals of 1' and 1''.

The feature of this walking device is that unlike a bicycle, the movement of the toes is in a semicircle with the diameter of the crank length, so the distance of movement of the toes at one time is large, and the flexion of the feet is also extremely large. , and the diameter of the bend is such that the foot must be stretched straight, which has the effect of giving the foot sufficient repeated bending and stretching movements.

The stride can be made suitable for adults and children by adjusting the crank length using the set screw 6.

Note that since the pedal is grounded to the ground by the rubber body 11 of the pedal, there is little shock.

Figure 5 shows a double crank type in which cylinders 5' and 5'' are connected to a horizontal shaft 8 perpendicular to the cylinders 5' and 5'' like a bicycle, in order to enable stable training for beginners. A movable sleeve 9 is provided, and a handle 10 perpendicular to the sleeve 9 is fixed, and the handle 10 can be moved by hand.
If you walk with your hands held together, you can easily maintain your body stability.
