Abstract

A multi-axial lever system is made by a system of three mobile levers (3, 6, 7). Two levers (3, 7) are pointed on a fixed part (4) with one lever (6) in connection between the others, pivoting in both. As the multi-axial lever system can transform a force exerted in one direction into another very different direction so the system can be used in a lot of appliances like tools, liquid and gas pumping bombing systems, pressing tools, vacuum bombs, cutters, stretchers, crabs, jacks and others.

Description

"MULTI-AXIAL LEVER SYSTEM"

The multi-axial lever system is a kind of lever coupling that transform the force done in one of it's extremity lever into another force greater in intensity in the other extremity lever, or the opposite effect

(X pursuant to in what extremity lever it's exerted

The size and structural composition, proportion or manner it is built, including the fixed part (4) shown in figure 1 , and the points of attachment of each pivoting lever, the multi-axial lever system can transform a force exerted in one direction into another very different in other direction. The

(o size of all the frame can vary hardly. It can use simple, double or multiplied numbers of levers for each said in the figure 1. (3), (4), (6), (7). The figure 3 shows the system using a double lever (24) in the place of the lever (6) seeing in the figure 1. The lever (3) in figure 1 give place to a not reinforced lever (25). The fixed part (4) shown in figure 1 was changed i 5 by a double support tower (26), to receive the pivoting levers (25) and (27). The weight is placed in the lever (27). One can change the size of the multi-axial lever system in all the frame or modify the relationship between the levers size. Some size changes can be done by adjustment apparatus, such as telescoping tubes, shown in figure 4, in order to io lengthen or shorten the arm reach. In this cases, the biggest tube (31), where pop pins (30) are attached adjust the length of the smaller one(32). The fixing points (5) and (22) from the levers (3) and (7), shown in figure 1 can be obtained by different places and structures, like pieces appendixes and others. ^•3, The multi-axial lever system can be used in lots of appliances, among all, tools, liquid and gas pumping bombing systems, pressing tools, vacuum bombs, cutters, stretchers, crabs, jacks, and others. As seen in figure 5, these kinds of pliers, where the called receiving lever (33), has a pivoting point (39) for the lever (37), that connects with the intermediate lever (35), and another to the mobile lever (36) and the mobile lever (34) has a pivoting point for the intermediate lever (40), coupling them one to another, and resulting in a big force gain. Figure 6 has some cutting (42), pressing (41) pliers applications.. Both functions ^ can be seen in pliers types in the figure 7, that shows an adjustable one, proportioned by a articulated point (43). This points can be constructed in the multi-axial lever system pliers by various manners, as like by a window made in the receiving lever (33), and the eccentric pin placed in the lever (37) body. By compressing the point (44) in the lever (45), the

(O system is in action in figure 8 comprising the liquid or gas inside the cylinder (46), that is fixed to the arm (47) with a clamp iron (48), using the piston (49). There is a lever adaptation (50) for changing the curving force in a rectilinear force with little rotation of the lever (51). It does exists too much ways to fix the system base (54), including the used in this

I example, in a desk (52) with screws (53) Some valves (55) was drawing for illustration. In figure 9 the system was used in a pressing tool. The piece (56), the form (57) and the pattern (58), mounted over a desk (59) can substitute hydraulic mechanisms by using the system for light works, as seen too in figure 10. The possibility of connecting the system to other O mechanisms, like electric motors is seen in figure 11. The motor (63)force transmitted by the belt (64) that speeds the pulley transferring the force to the lever (66) using the lever (67). In this model the supporting arm (68) show an appendix (71).turning the lever (66) back, elevating the mechanical advantage to the lever (69). The generating force reaches the s2 ₎" second pulley, that can transmit it to lots of other applications. In the car elevator tool of the figure 12 by applying a force with the hand in the point (74), the metal sheet (79) push the car upwards, with little spin of the pivot (80). In application shown in figure 13, a great backward changing of the pivoting point (83) of the lever (84) was obtained putting the it in a different support arm from the lever (86) that has its pivoting point (85) in the support (87). This conception drawing is very different from others elucidated in this patent. In addition, the lever (86) is now firmly attached to a ratch (88) that is stopped by the action of the pin (89), and can x receive other apparatus to a lot of more functions, among all, , The intermediate lever (91) is both extremity pivoting.

There is no knowledge in the actual technical stage about a similar mechanism.

The utilization of the multi-axial lever system can be done, too, in _t o gymnastics exercising machines, as shown in figure 1. Some research prove that the use of the system in physiotherapy can contemplate the specificity of some movements, like in the extension of the knee. The quadriceps muscle has the property of having more force in the 90 degrees angle, for example than in the 180 degrees. This can induce the ^ professional of the physical rehabilitation in work the knee above or down its capacity. There is a great number of studies comporting the theory of the specificity movement law. for enhancing the physical performance in ballistics sports. Jumps, for example, can be perfectly worked in this machine. The invention can be better comprising for seeing the figure 1 that shows a lateral view of the machine. The system was already explained. This machine can offer much kinds of exercises, depending on the apparatus. The intermediate lever can be made of different formats, like "H" as seen in figure 14, and the machine can receive sensors of any l<, kind, including those of velocity, force, metabolism, oxygen consume, cardiac frequency, electric resistance, magnetic resistance, as show in figure 15, and other systems for controlling and stopping movement as shown in figure 16, where a sleeve artifact (94) can block the lever movement by obstructing the rack(97) Various protection articles can be used in this machine for preventing from accidents. In figure 17 there is an example of a grating. The platform (12) of figure 1 can be designed in a great variety of ways, as shown in figure 18 and 19. The iron cable (15) can adopt various accessories , permitting exercising various muscular groups, among them, with the use of handle (20), bars, puling (not represented in the figures). Interceptions of the iron cable can be done in any height, for sitting, stand up and innumerable positions exercise types and machines.
