Device for aiding plantar flexor muscles

A muscle assist device comprising:

• a support clamp (1),
• a foot clamp (3), and
• at least one actuation mechanism (10) which attaches the support clamp and the foot clamp through an elastic element (2);
• wherein the at least one actuation mechanism (10) comprises an actuator with a linear actuation (26);
• a latch mechanism (25) having a toothed annular surface coupled to the linear actuation;
• a retractable rotating element composed of a toothed drum (24) and an elastic spiral element (23);
• wherein the toothed drum has an annular groove and the toothed drum corresponds to the toothed lock type mechanism;
• a rope (28) wound in the annular groove of the toothed drum with one end attached to the elastic element (2);
• and a casing (21, 27) for containing the elements of the drive mechanism;
• a control system comprising at least one sensor configured to detect the movement of the user's walk, a microcontroller configured to receive data from the at least one sensor and send a signal to the actuator with a linear drive to activate or deactivate the locking mechanism, and a battery to supply power to the control system. The support clamp (1) comprises at least an adjustable strap that embraces the front part of a calf in a transversal manner and supports the actuation mechanism in the rear part of the calf. The foot clamp (3) comprises a foot clamp structure (20) connected with a support sole (15) for the rear and lower part of the shoe that embraces and is fixed to part of a shoe externally, in order to be attached to conventional footwear and where the foot clamp structure has a protrusion (17) on its back where the elastic element (2) is placed.
