| Popis: | 96 Swimming is one kind of sports and exercises, which is very good to health and feasible for all people. So far, there is no learning or exercising device for swim. In addition, the outdoor swimming pools are not enough and their opening hours are limited as well. It is, therefore, inconvenient for the beginners and the exercisers. This paper presents a conceptual design of learning device for freestyle swimming. It could guide the required coordinated motion of hands and feet for the beginner. Firstly, we analyzed the paths of hands’ motion and path for freestyle from a motion picture with PhotoImpact software. The results of this analysis are used to synthesize the required cam mechanisms to guide the users to follow the motion of hands and legs. This design uses Pro/ENGINEER software to design parts and assemble those parts into the device. The feasibility of this completed device, which consists of cams, has been confirmed through the dynamic simulation in Pro/ENGINEER software. Regarding the exercising device of swimming, all available existing devices or in the patents do not provide the correct path of hands and legs in freestyle swimming for the users. Even though providing correct paths for exercising device is not so important, this function could be useful for the user to improve their swimming skill, and therefore it could optimize the exercising device’s function. The other purpose of this study is to design an exercising device in accordance with the paths obtained and the loads of freestyle swimming. A novel design of exercising device has been presented. Through the dynamic simulation in Pro/ENGINEER, its feasibility has been confirmed. |
