Abstract
A system (100) for leveraging force comprises a main crosspiece (2) having at least one first end (2a) and an opposite at least one second end (2b) end. The main crosspiece (2) is interconnected by means of an axle (5) with a static wheel (1) at a location (2c), in between the first end (2a) and second end (2b) of the main crosspiece (2), the static wheel (1) is characterized by a first diameter (D). The second end (2b) of the crosspiece (2) is configured to provide an output force Fout at second end (2b) correlated to (L/l)Fin, where Fin is an input force applied to the driving wheel (4), L is a distance between second end (2b) and the main axle (5) and Lis a distance between the first end (2a) and the main axle (5).
Claims6
A system (100) for leveraging force comprising a main crosspiece (2) having at least one first end (2a) and an opposite at least one second end (2b), said main crosspiece (2) is interconnected by means of an axle (5) with a static wheel (1) at a location (2c), in between said first end (2a) and second end (2b) of said main crosspiece (2), said static wheel (1) has a center and is characterized by a first diameter (D);
- a driven wheel (3), characterized by a second diameter (d), is interconnected, by means of a hinge (6) with said main crosspiece (2) at said at least one second end (2b);
- said first diameter (D) is configurable to be smaller, equal to, or greater than said second diameter (d);
- a surface of the driven wheel (3), and a driving wheel (4), is in non-slipping communication with a surface (1b) of said static wheel (1);
- said second end (2b) of said crosspiece (2) is configured to provide an output force Fout at second end (2b) correlated to (L/l) Fin, where Fin is an input force applied to said driving wheel (4), L is a distance between second end (2b) and said axle (5) and 1 is a distance between said first end (2a) and said axle (5), wherein output force Fout is not coaxial with the center of the static wheel (1), and wherein the correlation between Fin and Fout accounts for the structural dimensions of the driving wheel (4).
A method of leveraging force comprising steps of
- a. providing a main crosspiece (2) having at least one first end (2a) and an opposite at least one second end (2b),
- b. interconnecting said main crosspiece (2) by means of an axle (5) with a static wheel (1) at a location (2c), in between said first end (2a) and said second end (2b), said static wheel (1) has a center and is characterized by a first diameter (D);
- c. interconnecting a driven wheel (3), characterized by a second diameter (d), by means of a hinge (6) with said main crosspiece (2) at said at least one second end (2b);
- d. configuring said first diameter (D) to be smaller, equal to or greater than said second diameter (d);
- e. communicating in a non-slipping manner a surface of a driving wheel (4) with a surface (1b) of said static wheel (1);
- said second end (2b) of said crosspiece 2 is configured to provide an output force Fout at second end (2b) correlated to (L/l) Fin, where Fin is an input force applied to said driving wheel (4), L is a distance between second end (2b) and said axle (5) and 1 is a distance between said first end (2a) and said axle (5), wherein output force Fout is not coaxial with the center of the static wheel (1), and wherein the correlation between Fin and Fout accounts for the structural dimensions of the driving wheel (4).
