The invention elasticity (flexure mechanism) which can be used for a variety of purposes, such as for human, animal or mechanical devices and products of industrial, medical and training relates to a joint device. When referred to generally as a joint function of 1) transmit power of one side to the other; 2) if necessary converting the direction of the force to which the transmission; 3) movement on the one side and the other space outhouse that is a three-way and 3-way rotary linear motion exercise a certain direction and position can be restored during exercise; 4) form a structure of one side and the other one during the coupling; 5) while operating in one of the structures, the external force applied to peacetime eopeun, applying a separate external power above a certain intensity; 6) Once separated again comprises six functional characteristics such as to be re-combined to exert its original function. The joint function has been applied extensively in the animal, human, machinery and other industrial products.
Of the present invention it is more specifically to warping and of by the elastic force of the rotating means is installed into the joint means of the X-axis, Y-axis and Z-axis which linear movement in one direction is possible, and also altitude, azimuth and axial rotation of the elastic means and which in one direction of rotation this function, which is a rotating means in proportion to the force exerted by the elastic force of the elastic means is configured to be engageable or departure from the elastic joint means (flexure mechanism) joint device. The invention as well as to accurately reproduce the six joint function described above, is a separate one side of the joint and the other end mounted easily and conveniently inserted and to exert all of the original joint function. In particular, the move in proportion to the amount of force delivered is applied through the user around the joints of the installation object depicting a human body, when the more constant intensity force is applied, dislocation of course, applied to an easy joint device detachable relative to the amount of force the offer by, provides elasticity (flexure mechanism) joint device capable of contributing to a variety of application fields, such as those listed above for medical surgery, industrial products, such as animal, human, machine and industrial robot or rehabilitation.
