Document Type and Number:
WIPO Patent Application WO/2018/205894
Kind Code:
A1
Abstract:
Disclosed is an auxiliary device system for swimming. The system comprises a variable tail fin fixed rod (7), a variable tail fin device and a balanced force application device. The variable tail fin fixed rod (7) is arranged in parallel with shanks of a swimmer and is fixed with same. One end, towards the feet of the swimmer, of the variable tail fin fixed rod is connected to the variable tail fin device, and one end, towards the thighs of the swimmer, of the variable tail fin fixed rod is connected to the balanced force application device. Secondary tail fins (2) at left and right sides of the variable tail fin device are respectively arranged at left and right sides of the variable tail fin fixed rod and are respectively connected to the variable tail fin fixed rod (7) by means of respective main and secondary fin hinge structures (3). Left and right variable fin pedals (6) above the secondary tail fins (2) at left and right sides are respectively hinged to the variable tail fin fixed rod (7) by means of ankle hinge structures (5). The auxiliary device system for swimming may also comprise a tail fin electric control device and a rod body electric control device. The left and right variable fin pedals are respectively connected to the secondary tail fins (2) at left and right sides and knee and hip elastic components by at least one of respective linkage components by means of electrically controlled force transfer or purely mechanical force transfer.
