きない。Problems that the invention aims to solve With the conventional chain-based interlocking system, there is no slippage during drive, but with the belt-linked system,
If there is slack in the tension of the belt, it has the disadvantage of causing slips. If the tension of the belt is tightened to eliminate slips, rotational resistance will be large and smooth transmission will not be possible.

動調整装置にある。Means for Solving the Problem In a belt-linked petal-driven fitness machine in which a belt is stretched between a pulley mounted on the crankshaft and a small-diameter pulley mounted on the axle of the adjustment wheel, the elbow 6a is attached to the frame rod 7. Rolling wheels 8 and 9 are attached to both ends of an L-shaped lever 6 that is pivoted on a support shaft 11, and the elbow portion 6
One wheel 8 having a larger distance from the support shaft 11 of a
on the upper surface of the upper stage side of the tension belt 5, and the other wheel 9 with a smaller interval on the lower surface of the lower stage side, respectively.
It is characterized by utilizing the elasticity of a torsion coil spring 10 wound around the support shaft 11 of the elbow part 6a of the shaped lever 6 to abut against the belt 5 without loosening it.
This is in the belt tension automatic adjustment device of a belt-linked petal-driven health machine.
作 用

するので緊張し、転車９をバネ１０の弾圧作用に
抗して押し上げ、レバー６を回動させ、転車８を
上段側ベルトに上方から押圧し、両方向から張架
ベルト５を緊張させるものである。Since the main function is configured as described above, when the pedal is stepped on to ensure a healthy start, the pulley 1 pulls the lower belt of the belt 5 from the direction of its rotation, causing tension and causing the rolling wheel 9 is pushed up against the elastic action of the spring 10, the lever 6 is rotated, the wheel 8 is pressed against the upper belt from above, and the tension belt 5 is tensioned from both directions.

さによつて変わり、本案では上段側の転車８の間
隔が大きくとられているから拡大回動し、ベルト
の上段側を大きく押さげるのである。 In particular, since the lower side of the belt transmits the rotational force of pulley 1 to pulley 4 through the amount of friction or engagement force between the two, the rolling wheels on the lower side move up and down depending on the tension of the belt, and this rotation The movement varies depending on the length of the spindle 11 of the L-shaped lever 5 and the length at which each wheel is located.In this case, since the distance between the wheels 8 on the upper stage side is large, the rotation is expanded, and the upper stage of the belt It pushes down the sides a lot.
プーリー１の駆動力が軽くなると、ベルト５の
下段側ベルトの緊張が解除されるから、バネ１０

度のテンシヨンが加えられる。 When the driving force of the pulley 1 becomes lighter, the tension on the lower belt of the belt 5 is released, so the spring 10
The belt 5 returns to the pressure contact due to the elastic action of the belt 5, and an appropriate tension is applied to the belt 5.

Reference numeral 1 denotes a large-diameter V-pulley mounted on a crankshaft 2, and a V-belt 5 is stretched between this pulley and a small-diameter V-pulley 4 mounted on the axle of an adjustment wheel 3. 6 is an L-shaped lever with an elbow 6a rotatably supported by a support shaft 11 on a frame rod 7, and wheels 8 and 9 are attached to both ends of the lever.
The lever part 6b on the side where the wheel is attached is made longer, and the distance between the wheel 8 and the support shaft 11 is set to L1 , and the other wheel 9
The lever portion 6c on the side where the lever is loosely attached is shortened, and the distance between the wheel 9 and the support shaft 11 is set smaller than L1 .
The wheel 8 is placed on the upper surface of the upper stage side of the tension belt, and the wheel 9
is arranged on the lower surface of the lower belt as shown in the figure, and is wrapped around the support shaft 11 of the elbow 6a of the lever 6, with one end fixed to the frame rod 7 and the other end attached to the back of the lever part 6c of the lever 6. The rolling wheels 9 and 8 are brought into pressure contact with the belt surface by the spacing L 1 :L 2 of the lever parts 6b and 6c by the elasticity of the torsion coil spring 10 pressed against the belt 5, and the belt 5 is pressed against the V pulleys 1 and 4 without slack. It was designed to be hung up.

ならしめる効果がある。 In particular, when a high load is applied to the belt at the time of starting the pedal, or under other conditions, the rolling wheels rotate in relation to the load, tensioning the tension belt. The supporting L-shaped lever is long on the upper side and short on the other lower side, and the lower side of the belt is set to transmit rotational force, and is attached to the wheel L-shaped lever with the smaller rotation stroke. Because it rotates the L-shaped lever against the elasticity of the spring,
As the rotation stroke of the upper wheels of the belt increases, the upper side of the belt is pushed down, and the higher the load is applied, the more the tension belt is tightened by both wheels, causing slippage or tooth skipping between the belt and pulley. This has the effect of preventing dangerous idling and ensuring reliable transmission.
