Technical Field :-
[0002] The present invention named as "Lever-arms swinging in non-vertical plane, pulled by non-vertical cable extending at right angle to lever-arm" relates to Fluid mechanics branch of physical-sciences.

Background:-
[0003] Nowadays we are using many types of means for mechanical advantage like chain hoist hanged from a column, lever-arms swinging in vertical plane, and the set of pulleys and chains, etc...

Present problems:-
[0004] Nowadays, the above said type of means for mechanical advantage are costly when used as the onsite fixed means for mechanical advantage because those require construction of columns or portal frames capable of resisting shear stresses and bending moments induced on them. We are in need of simple low cost means for mechanical advantage.

Objectives of the invention:-
[0005] Objective of the invention is to develop 'a low cost stationary means for mechanical advantage suitable for using it as stationary means for mechanical advantage in industries and also in other utilising devices.

Summary of the Invention:
[0006] The present invention named as "Lever-arms swinging in non-vertical plane, pulled by non-vertical cable extending at right angle to lever-arm" consists of one or more lever-arms. For higher mechanical advantage, set of two or more interconnected lever-arms is used. Each one lever-arm is anchored to horizontally rotatable hinge (20) allowing swinging of lever-arm in horizontal plane. The 'effort arm (90)' is attached to a chain extending horizontally to a pulley supported over a column or on opening of a vertical pit or bore (170). The chain passing over the pulley is extended downwards, and turned extended vertically into the deep pit or bore (170). The chain's vertically hanging part is attached with objects having sufficient weight at its lower end. The downward pulling force exerted by the hanging loads (180) on the chain is transmitted through the horizontal top part of the chain as horizontal pulling force to the effort arm (90) of the lever-arm. The said lever-arms are used as the means for mechanical advantage to convert momentum of 'hanging load (220) moving longer distance' into 'a heavy force moving short distance', and the magnified force is transmitted through resistance arm (100) to apply on the objects attached at outer end of the resistance arm (100).
[0007] The lever-arm's fulcrum is a rotatable anchoring hinge (20) capable of resisting horizontal pulling forces and vertical loads and moments induced in it. The said hinge (20) is anchored to a pedestal extending into the ground and its footing is provided with outward cantilevering projections along its vertical faces or at its bottom side, and at both of bottom face and vertical sides also to resist horizontal pulling forces and moments exerted on the pedestal.
