Title:
ONSHORE BREASTSTROKE LEARNING MACHINE AND TRAINING TIME INCREASING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/056937
Kind Code:
A1
Abstract:
An onshore breaststroke learning machine, comprising an upper limb movement mechanism (1), a trunk movement mechanism (2), and a lower limb movement mechanism (3). The upper limb movement mechanism (1) comprises upper limb tracks (11), arm pull slider assemblies (12), a motor induction switch (13), and a lower limb stopper induction switch (13). Each arm pull slider assembly (12) slides to the initial position of the arm pull state along the corresponding upper limb track (11), and the motor induction switch (13) sends a signal to control the trunk movement mechanism (2) to act. When the arm pull slider assemblies slide to the upper limb withdrawing positions, the lower limb stopper induction switch (13) sends a signal to control the lower limb movement mechanism (3) to complete a leg drive movement. The lower limb movement mechanism (3) comprises lower limb tracks (31), leg drive slider assemblies (32), foot hitching plates (33), first connectors, and lower limb stoppers (35). The leg drive slider assemblies (32) slide to the lower limb withdrawing positions along the lower limb tracks (31), the lower limb stoppers (35) receive the signal of the lower limb stopper induction switch (13), and the sliding is allowed or stopped. Also provided is a training time increasing device. By means of the onshore breaststroke learning machine, the standard breaststroke movement gesture and the coordination of the movement time can be ensured.
