1. A single point torque adjusting mechanical assembly, for assisting musculoskeletal activities, characterized in that the said assembly comprising of:
an upper element (101′);
a lower element (102′);
a resilient means (105′) with fixed end and free end (119′);
a flexible inextensible element or rope (114′);
a hinge pin (110′) and a shaft (118′);
a load/torque adjusting means (108′) having a single point at its free end (116′);
wherein the assembly varies the torque non-linearly by adjusting a lever arm length such that fixed end of the resilient means 105′ need not be displaced;wherein the upper element (101′) is moveably secured with lower element (102′) by the hinge pin (110′) and shaft (118′), and one end of the load adjusting means (108) is moveably connected with a secured end of upper element (101′),
wherein the flexible inextensible element or rope (114′) is moveably secured with/between the free end (119′) of the resilient means (105′) and hinge pin (110′) and such flexible inextensible element (114′) passes through the free end (116′) of the load adjusting means (108′), wherein the length of the flexible inextensible element or rope (114′) is equivalent or equal to sum of distance between the hinge pin (110′) and the free end (116′) of load adjusting means (108′) and distance between free end (116′) of load adjusting means (108′) and the free end (119′) of the resilient means (105′), wherein the sum of such distance remains constant; and
wherein the said load adjusting means (108′) slides over lower end of the upper element (101′) and the lower element (102′) to change lever arm length to produce non-linear variable counter torque.
