Description

[Detailed description of the invention]

[0001]

[Industrial application] This invention is based on the concept that when pedaling, the pedal stepping plate swings back and forth and up and down, so that the arch can be massaged while pedaling, and the torque of the pedaling pedal can be efficiently reduced. The present invention relates to a tread plate swinging device that can transmit a signal to a pedal.

[0002]

2. Description of the Related Art Conventionally, a pedal of a bicycle or the like is rotatably attached to a crank. The pedal that transmits the torque of the foot to the crank performs a turning motion while being in contact with the sole of the foot. In the course of the turning movement, a projection is provided on the surface of the pedal in order to make it easier for the foot to be caught on the pedal and to prevent slippage.

[0003]

However, the above-mentioned projections are provided solely for the purpose of preventing slippage, and do not provide a sole massage effect. It is an object of the present invention to provide a massage effect such as acupressure of the sole and kneading during the pedal operation.

[0004]

Accordingly, the present invention is directed to a support plate 2, 2 provided on the left and right sides of a pair of girder plates 1, 1 opposed to each other at regular intervals.
At the center, a bearing shaft 7 having two eccentric cams 8a and 8b formed in the longitudinal direction is attached, and a pair of L-shape and inverted L-shape divided to the bearing shaft 7 is provided. In addition to loosely fitting the treads 4a and 4b, horizontally long fitting holes 6 and 6 are formed in the beam direction of the treads 4a and 4b.
The support shafts 2 and 2 are loosely fitted in the fitting holes 6 and 6, and the pedals 4a and 4b swing back and forth and up and down by pedaling.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, step plates 4a and 4b to be described below are interposed between beam plates 1 and 1 arranged at regular intervals. The housing 3 is formed by being mounted via the support shafts 2 and 2 respectively.

[0006] Stepping plate 4 housed in housing 3
a and 4b will be described. The tread plates 4a and 4b are provided in pairs with each of the tread plates being partly omitted. Here, the chipping means a joint that is formed by cutting each half and combining them to form a united shape. Specifically, an L-shaped and an inverted L-shaped combination Can be exemplified. As another example, a pair of treads divided into a combination of irregularities can be exemplified. In addition, each step board 4
A number of projecting bosses 5 are provided on the upper surfaces of a and 4b.

In the direction between the beams of the tread plates 4a, 4b, the support shaft 2,
2 is provided with a horizontally long fitting hole 6 to be inserted. Further, through holes 9a and 9b for fitting eccentric cams, which will be described below, are provided in portions where the step plates 4a and 4b are formed with a gap.

FIG. 3 shows a rotary shaft 7 provided with two eccentric cams 8a, 8b to be inserted into through holes 9a, 9b formed in portions where the above-mentioned tread plates 4a, 4b are incomplete.
In the illustrated example, the eccentric cams 8a and 8b have a phase difference of 180 °.

The shaft 7 is pivotally supported at the tip of the arm of the crank of the bicycle, and the tread plates 4a and 4b are incorporated into the housing 3 via the shaft 7.

FIG. 4 shows a change in the position of the pedal due to the turning of the crank 10 of the bicycle, and the operation state of the tread plate at the changed position of the pedal.
In FIG. 4, when the pedal is at the position indicated by a-2, the tread plate is in the operation state indicated by a-1.
-2, c-2, and d-2, the tread is b
The operation state shown in -1, c-1, and d-1 is set.

If the position of the pedal shown in FIG.
At -1, the eccentric cam 8a indicated by a dashed line is in a state of protruding upward. On the other hand, the eccentric cam 8b shown by the solid line projects downward. This is because the eccentric positions of the two eccentric cams are different by 180 degrees.

The rotation of the shaft 7 causes the eccentric cams 8a and 8b to move the tread plates 4a and 4b up and down and back and forth, respectively, and this state is as shown in FIGS. .

The above and below and up and down movements of the treads 4a and 4b respectively move the treads 4a and 4b up and down in steps, or move in the back and forth direction.

Thus, the synthesizing operation of the treads 4a and 4b is transmitted to the sole of the pedaling foot via the boss 5,
It produces a massage effect.

Although the above description is about the use of a bicycle pedal, the present invention relates to a foot-type health appliance (for training,
FIG. 5 illustrates this example, wherein A is a plan view and B is a side view. Hereinafter, this will be described.

Reference numeral 11 denotes a housing 11 supported on support legs 11a.
b, which is provided with a seat 12, a handle 13 and a pedal device 14. Then
The configuration of the tread plate 14a of the pedal device 14 is the above-described configuration using the eccentric cam, and can be swung back and forth and up and down.

With this device, the pedal device 14 can be automatically rotated via a motor 15 and a clutch 16 built into the housing 11b and a reduction mechanism 17 using a worm and gears. The operator operates the operation button and lever 18 provided on the handle with the handle 13 held by the hand, and the crank 10 is automatically rotated to allow the sole on the foot plate 14a to be operated. Massage.

In the above, training is performed by using a normal bicycle when the clutch 16 is disengaged. On the other hand, when the clutch 16 is engaged, the motor 15 uses a dynamo, so that the load resistance can be appropriately changed. It is possible to carry out leg training.

[0019]

[Effects of the Invention] As described above, the present invention makes it possible to naturally massage a leg or the like by using a pedal while running while using a bicycle outdoors. However, rehabilitation and training indoors It can also be used effectively as a health appliance for children.
