Definitions
- the muscular propulsion of a vehicle requires the transformation of the alternative movements of the limbs, arms. or legs of the human body in a unidirectional rotation of the rotary drive member.
- One of the most well-known means of transformation is the crankset used on bicycles, which is simply a system for driving a wheel by two cranks offset by 180 ° relative to each other. The torque resulting from the application of a force on these cranks varies as a function of the angular position of the cranks relative to the direction of the force exerted.
- the crankset is indeed a mechanism for transforming alternative movements of the legs or arms into a continuous rotary movement insofar as the drive is obtained only during a half-rotation of each crank following the extension of the respective legs.
- the movement of the legs is not a simple extension movement, since the feet follow the rotation of the pedals so that the legs perform a real connecting rod movement.
- This movement is especially suitable when the position of the body is substantially vertical or when the body is leaning forward like on a bicycle.
- this connecting rod movement is less easy to execute from a seat with the body tilted backwards. In addition, in this tilted back position, the body weight cannot be used to strengthen muscle action.
- crankshaft is provided with a connecting rod intended to be actuated by an oscillating lever.
- additional energy supply which can be obtained by this system is low.
- it has the drawback of associating two drives, one using a rotation, the other an oscillation, and that the synchronization of the two movements is physiologically difficult to achieve.
- the object of the present invention is to remedy, at least partially, the drawbacks of the above-mentioned solutions.
- the subject of this invention is a muscular propulsion device, in particular for a vehicle having at least three support points, comprising a pair of levers, articulated around a common axis, two flexible transmission elements fixed by one of their respective ends to the respective levers at a certain distance from the pivot points of these levers and at their other ends to respective return springs, each of the transmission elements being connected to the drive shaft of the vehicle by a fiber wheel mechanism.
- This device is characterized by the fact that said return springs consist of two blades wound in a spiral, one of the respective ends of which is integral with the second end of one of said transmission elements, while the other of these ends is integral with the hub of a freewheel mounted coaxially with said drive shaft, the whole being arranged so that the restoring force exerted on said transmission element is substantially constant.
- Figure I very schematically illustrates the propulsion device according to the invention which essentially comprises two levers and the articulated about a common axis 2 and which end with pedals 3.3a.
- Each lever I, Ia is connected to a drive shaft 4 via a cable 5.5a and a return spring 6.6a.
- These springs consist of blades wound in a spiral around the shaft 4 in the rest position and fixed to this shaft by one of their ends, while the other end of each spring is fixed to one of the cables 5.5a.
- These cables are fixed to the levers 1,1a by means of respective slides 7,7a.
- FIGS. 9 and 10 illustrate the detail of the fixing of the cable 5 to the lever I. It can be seen that the cable 5 must constantly make an acute angle with the tangent to the curvature of the lever 1 passing through the anchoring point of the cable 5 This acute angle ensures a force which constantly tends to pull the slider 7 towards the end of the lever I. Cables 8, 8a retain the respective sliders 7, 7a passing around the pivot axis 2 of the levers 1, 1a and are fixed to the chassis of the vehicle by an adjustment member 9 illustrated in more detail in FIGS. 9 and 10. As can be seen, this adjustment member 9 has an operating handle 9a, integral with a pawl 9b in engagement with a rack 10 secured to the vehicle frame under the action of a spring II.
- the displacement of the pawl 9b along the rack 10 makes it possible to modify the length of the cables 8, 8a between the axis 2 of the levers I, la and their respective anchoring points to these levers. Consequently, the anchoring points of the cables 5, 5a relative to the axis of the levers 1, 1a are adjustable by this means. As a result, the ratio between the angular displacement of the levers and the number of turns of the drive shaft 4 is variable.
- FIGS. 2 and 3 illustrating a vehicle whose propulsion device is based on the principle of that illustrated diagrammatically in FIG. 1.
- the entire propulsion device with its mechanism for changing the transmission ratio is mounted, in this example, on a three-wheeled vehicle 12a, 12b and 12c, two of which are at the front and one at the rear, mounted on a frame 13 carrying a seat 14 and a backrest 15.
- the propulsion device of the figure is associated with a second pair of levers 16 and 16a articulated around an axis 17 parallel to the axis 2. These levers are articulated furthermore to two respective control rods 18, 18a which terminate in handles i9, respectively 19a.
- FIG. 4 illustrates the detail of the connection mechanism between the levers 1, 1a on the one hand, and 16, 16a on the other hand.
- the levers 16 and 16a are integral with two respective shafts 20, 20a coaxial with the axis 17 and independent of each other.
- the shaft 20a is integral with a freewheel clutch member 21a associated with a pinion 22a, pivoted around the shaft 20a.
- the shaft 20 is integral with a freewheeling clutch member 21 associated with a pinion 22 pivoted around the shaft 20.
- Each of the pinions 22 and 22a is engaged with a pinion 23 respectively 23a coaxial with the hinge axis 2 of the levers 1, 1a, these pinions 23, 23a being integral with these respective levers. It follows from this arrangement that, the driving stroke of the levers 1, the occurring when sator pushes with the feet (see fig. 2) on the 3, 3a, the one-way clutch between the pinions 22, 22a of a and 23, 23a on the other hand must be chosen so that the pinions 22, 22a are driven by the clutch members 21, 2la 'when a pull of the arms is exerted on the levers 16, 16a by means of the rods 18 respectively 18a.
- the pinions 22, 22a being in direct engagement with the pinions 23 respectively 23a, they therefore rotate in opposite directions to one another, so that the levers l, la are motors during an extension of the legs , while the levers 16, 16a are when pulling the arms.
- This movement corresponds substantially to that of a rower.
- two possibilities are offered, in one case, the movements of the left members are in phase with those of the right members, in the other case, they are out of phase, thanks to the device illustrated in FIG. 5.
- the drive mechanism described therefore offers great flexibility in the choice of movements.
- the freewheeling connection between the levers 1, the on the one hand and 16, 16a on the other hand makes it possible to use either the legs or the arms separately, or even the legs and the arms simultaneously.
- the respective movements left and right limbs can be alternated in particular the support 25 is angularly blocked or, if this support 25 is unlocked, the movements of the legs and those of the arms can be in phase like the movements of a rower. It is this latter case which makes it possible to obtain the maximum instantaneous energy while the phase shifted movements make it possible to obtain a substantially continuous energy production.
- FIG. 6 illustrates the energy transmission mechanism of the levers 1, 1a, 16, 16a on the rear wheel 12.
- the springs 6, 6a are fixed by one of their ends to a freewheel clutch member, of which one 30 is visible in section in FIG. 6.
- This member is associated with the hub of the wheel 12c, the clutch between the member 30 and this hub being chosen so that the drive of the hub occurs when a traction is exerted on the return spring 6.
- the advantage of this arrangement lies essentially in the fact that a spring such as the spring 6 has properties similar to a clockwork movement mainspring, the essential difference residing in the fact that it works in the opposite direction, that is to say, it arms when you unwind it and disarms when you wind it. This difference comes only from the shape initially given to this spring.
- the clockwork movement spring is capable of delivering a substantially constant force over the major part of its disarming curve. Consequently, the return force of the springs 6, 6a is very little dependent on the travel of the cable anchoring points 5, 5a on the levers 1, la.
- the return force practically does not increase as a function of the length of the stroke of the element flexible transmission. Consequently, the loss of energy can be considerably reduced, in particular when the transmission ratio is high, that is to say when one chooses a long travel of the cables 5, 5a, using the adjustment member 9.
- the two levers 1 and 1 are made kinematically integral one by blocking the tenon 26 by the lever 28, the energy the reinforcement of the respective return springs 6,6a is partially operated by the other lever when disarming the same spring.
- rods 18 and 18a can be oriented around their respective longitudinal axes and act on respective cables mounted in sheaths 31, 31a respectively like the bicycle brake cables and which are fixed. to levers 32, respectively 32a connected by a rod 33 and integral with the axes of articulation of the orientation arms 34a, 34b of the wheels 12a respectively 12b.
- the variant of FIG. 11 differs from the embodiment described above, essentially as regards the connection of the drive by the arms with the pedal drive levers. This variant mainly aims to make the construction lighter.
- the drive by the arms comprises a tubular guide member 40 in which two rods of semi-cylindrical sections are slidably mounted, each being integral with a lateral handle, one of which 41 is visible in FIG.
- Each rod housed in the guide member 40 is connected to one of the pedal levers 1 ', 1'a quite similar to those of the embodiment previous, by a 42.42a cable passing around a double 43, pivoted on a flange 44 secured to the chassis 45 and fixed anchoring element 46, respectively 46a.
- the cables 8 ', 8'a are used, as in the previous embodiment to adjust the position of the slides 7', 7'a along the levers for this purpose are attached to their other extremities at 9 'slidingly mounted along the tubular guide member.
- the vehicle drive mode is completely identical to that of the previous embodiment and therefore does not need to be described.
- the propulsion device described can be used for any type of vehicle having at least three support points.
- This device can also be adapted to an instrument intended for indoor muscle training.
- only the rear wheel 12c is necessary, this wheel being engaged with a member intended to create a certain resistance, in order to simulate the conditions of propulsion of a vehicle.
- the vehicle can be simplified, in particular the front wheels and the vehicle guiding device illustrated in FIGS. 2 and 3 can be omitted.
