Abstract

The arms of the leverage are basically arranged to form a scissor-type movement. This feature is generally used in cases where a wiper action over a wide area is required. In prior designs rotatry joints were used which have a prerequisite of the pivots being placed accurately in parallel position to each other, or else jamming and excessive wear and tear occurs. The present design envisages the relationship between number of rotary joints, ball joints, number of elements and number of degrees of freedom according a specific equation hereby permitting a great number of combinations of the above elements. The mechanism is functional and working without excessive additional plays in the joints.
