DESCRIPTION

CONVERTER MECHANISM OF THE MOVEMENT OF TILTING STEPS (PUSH-PULL) INTO A UNIDIRECTIONAL ROTATING MOVEMENT OF

AN OUTPUT AXIS

The present invention refers to a new mechanism that converts two way pedal movements (to) and (fro), into one-way direction of rotation on an output axle shaft.

The mechanism was mainly created to drive pedal powered diversion vehicles, and other apparatus.

The mechanism incorporates, on its composition, two innovating features that give it a larger versatility, easier handling, and better outcome and comfort.

Function addition of rotations: due to an arrangement on its planetary gears system, the mechanism provides a rotations ratio in-out, that doubles the number of rotations, conventionally obtained, with the same angle of the pedal torque, and size of gears on a similar planetary gear system.

Function of gradual increase of rotations: the device makes it also possible to increase gradually, through the pedal (to) power movement, with angles of 10° to 180°, into high values of rotation, on its output axle shaft. On this function, the rotations are gradually increased due to the rotations provided by each pedal stroke to be added to the rotations of the output axle, which continues to rotate, driven by the load on the rotating output axle, with which it is consistent. The increase of speed given by each pedal stroke depends on the skill and power applied to the pedals by its human operator.

The device permits the reciprocal pedaling, the step by step pedaling, where one foot is steady while the other foot does the up and down moves, or even the pedaling (to) and (fro) with the two pedals simultaneously.

The output axle shaft which can make the wheels of a vehicle to rotate, the helix of a boat or other device, is locked on a backward state of rotation.

In order to have a better understanding of how the mechanism works, so far as its composition, its operation and practical applications are concerned, the following description is illustrated by the appended drawings, only with an exemplifying purpose.

The 1 to 7 figures show the frontal and sideward views of the mechanism and the parts that incorporate it, with the purpose to help to explain how it works.

Examples of how the mechanism works

Having as a point of reference the drawing of the Fig. 7/7, which incorporates all the parts of the entire mechanism, we see that the pedal crank (15) and the pedal (17) are rigidly connected through the axis (22), to the annulus (1 ).

On this way whatever the movement of the pedal, it will be the same on the annulus (1 ).

On the active pedal stroke (to), the pedal and the annulus (1 ) rotate on the direction right-left, being so the active power direction of rotation of the annulus (1 ). The annulus (1 ), have on its interior cogs meshed with the planets (2) and (3), which on its turn rotate on the right-left direction.

The planets (2) and (3) are meshed also to the sun wheel (4) which is rigidly connected to the output axle (10), and so as the planets (2) and (3) rotate on the direction of the annulus (1 ), that is right-left, they make the sun wheel (4), and the output axle (10), rotate on the left-right direction.

If we admit that the annulus (1 ), has 100 cogs inside, and the sun (4), has 40 cogs, it would mean that 1 revolution of the annulus (1 ), would provoke 2,5 revolutions on the sun (4), and the output axle (10).

Addition of rotations

Given that the annulus (1 ), is also meshed through its diagonal outer top side, through the cog wheels (05) and (5), to the cog wheel (7), that means that one rotation of the annulus (1 ), on the direction right-left, provokes one rotation of the cog wheel (7), on an inverted way, that is left- -right.

The cog-wheel (7), is coupled, through the free-wheel (8), and on its traction way, to the planet carrier (6), on the left-right direction, and on the carrier (6), are connected the axes (11 ) and (12), of the planets (2) and (3). On this way, the planets (2) and (3), rotate on the direction right-left, and their axes (11 ) and (12), on the direction left-right, and at the same time, which results that the planets (2) and (3) rotate at about the double speed of the basic relation in-out 1 -2,5, which means that one revolution of the annulus (1 ), causes the sun wheel (4) and the output axle (10) to

rotate about 100% faster, that is, 1 revolution of the annulus (1 ), provokes 5 rotations of the output axle (10).

This means that the sun wheel (4), and the output axle shaft (10), rotate now about 6 rotations for each rotation of the annulus (1 ), due to the effect of addition of rotations, provoked by the movement of the axes (11 ) and (12), and the planets (2) and (3), dragged by the planet carrier (6), and the cog- wheel (7), on the opposite direction of the annulus (1 ).

In order that on the return movement of the pedal (17), the annulus (1 ), and the cog-wheel, don't exercise rotating, power over the planet carrier (6), there is a free-wheel (8), between the lateral side of the cog-wheel (7), and the axis of the planet carrier (6).

On this way the cog-wheel (7) drags the planet carrier (6), on the direction right-left of the annulus (1 ), and the planets carrier (6), is released from the cog-wheel (7), on the left-right rotation of the annulus (1 ).

On the other hand, the rotation of the output axle (10), and the sun-wheel (4), due to its inertia of rotation, originate the sun wheel (4) to drag the planets (2) and (3), in the interior of the annulus (1 ), on the right-left direction, without those to exerting any traction upon the annulus (1 ).

However, if meanwhile, the annulus (1 ), rotates on the right-left direction, it originates the planets (2) and (3), to rotate with additional speed to its free rotation inside the annulus (1 ), originated by the rotation of the output axle (10), and the sun wheel (4), when this is superior to the rotation of the planets carrier (6), which is dragged by the cog wheel (7), at the inverted speed of the annulus (1).

The mechanism is formed of two alike planetary groups, assembled on the opposite ends of the frame (20) of the mechanism, and for convenience sake, the description of it has been done, up to now, refers only to one of these two planetary groups, remaining easily understood how the other planetary group works.

Gradual increase of rotations

The gradual increase of rotations is a phenomenon that takes place with each pedal (to) and (fro) movement, when observed the conditions that determine the procedure to the increase of rotations.

Taking as a reference, as example of demonstration, the frontal view of the mechanism we suppose that:

1 - The active power movement of the pedal (to), is on the direction of rotation right-left, which makes de planets (2) and (3), rotate on the same direction, and simultaneously the sun wheel (4), and output axle to rotate on the left-right direction, and on the same manner, with the equivalent direction, the axes (11 ) and (12) of the planets (2) and (3), which goes solidary with the planets carrier (6), which axes (11 ) and (12), on its turn drag the planets (2) and (3), inside the annulus (1 ), on the direction left- right.

2 - Due to the inertia provoked by the load moved by the axle (10), this drags the planets (2) and (3), and continue their course of rotation inside the annulus (1 ).

3 - Due to the action of the free-wheel (8), the annulus (1 ), remains free, and is not dragged by the planets (2) and (3), being able to make its return (fro) freely.

4 - While the planets (2) and (3), are rotating freely in the interior of the annulus (1 ), if the annulus (1 ) starts rotating on the direction (to), right-left it only exerts traction over the planets (2) and (3).

If its rotation speed is superior to the rotation of the planets (2) and (3), which move freely on the direction left right, but rotate on the direction right-left, on the inside of the annulus (1 ).

5 - In order that the annulus (1 ), may have immediate power traction over the planets (2) and (3), the sun (4) and the output axle (10), the annulus (1 ) and the planets (2) and (3), must rotate at about the same speed. In order that the annulus (1 ), on its rotation movement of return (fro), should rotate with the same, or close speed, of the planets (2) and (3), and their axes (11 ) and (12), and that its rotation be reversed immediately to the right-left direction, (to), which will provoke full traction over the planets (2) and (3), and increasing with this procedure the rotation of the planets (2) and (3), which on its turn will increase the existing rotation of the sun (4) and the output axle (10).

6 - One pause between the return (fro) and (to) movement of the pedal will lessen the increase of rotations, being this action described on point 4.

7 - On this way the conditions necessary to provoke the gradual increase of rotations, are basically as follows: - a quick return of the pedal (fro), followed by an immediate and fast pedal (to) stroke done by the same pedal.

As it is understood from the anterior description, this mechanism can have application to other different types of machines or devices.

There are also possible alterations on the described model presented, without any limitations of its character, since that the same are not out of the character and field of the claims.
