陆上蛙泳学习机及增加训练时间装置 技术领域
本发明涉及健身器技术领域，尤其涉及一种陆上蛙泳学习机及增加训练时间装置。

蛙泳是游泳初学者的学习项目。人工教学蛙泳时，由于学习动作的标准性及动作时间的协调性难以在短时间内完全掌握，学习期间特别容易呛水，延长初学者的学习时间，或者造成初学者恐惧心理，放弃学习游泳，费时失事。
除了人工教学蛙泳，现有技术的一种游泳学习机，是陆上的柱子连接的配有安全带的吊篮，吊篮固定在人的胸部，把人吊起悬浮在水中，手脚在水中模拟各种游泳动作。该技术方案的缺点是虽然保证了人不至于呛水，但是手脚游泳姿势的标准性正确与否不能快速反馈给自己，从而和人工教学一样，并不能得到有效快速地改善。

其中，上肢运动机构1，包括上肢轨道11、划水滑块总成12、电机感应开关13和下肢止位器感应开关14；划水滑块总成12沿上肢轨道滑行11，在上肢划水状态起始位置处，也即上肢与下肢伸直成一条线时左右手臂的外侧处，上肢轨道11设置电机感应开关13，控制躯干运动机构2动作；在上肢收手臂位置处，上肢轨道11设置下肢止位器感应开关14，控制下肢运动机构能够完成一次完整的蹬腿动作，。划水滑块12总成包括四个万向轮或万向球121、滑块板122、 十字轴123和翻动板124，上肢轨道11为U型槽，见图3；滑块板122上板面设置一对间隔设置的L型连接件1221、1222，翻动板124的下板面设置一对间隔设置的L型连接件1241、1242，十字轴123分别贯穿L型连接件1221、1222和L型连接件1241、1242上的轴孔从而转动连接滑块板122和翻动板124，方便手臂划水时，手腕扭转差的释放。四个万向轮或万向球121设置在滑块板122的下板面，在上肢轨道11的U型槽内运行。
躯干运动机构2，包括承托台板21、铰链22、翘动板23、调速电机24、偏心轮25和摇杆，承托台板21固定在台架上，承托台板21通过铰链连接翘动板23的一端，翘动板23的另一端通过摇杆与偏心轮25连接；调速电机24位于翘动板23的上方，接收电机感应开关13的信号驱动偏心轮25带动翘动板23上下活动，模拟蛙泳躯干在水面上下起伏的换气动作。
翘动板23与偏心轮25的另一种连接方式为：偏心轮25一侧面轴心连接电机24，偏心轮25的另一侧面轮的边缘设有一个与之转动连接的连接块26，一根软绳28穿过连接块26上的通孔27，两端固定连接在翘动板23的另一端上。
躯干运动机构2的另一个实施方式为：躯干运动机构2包括可调速电机201、伸缩杆202和躯干支撑板203；三者顺序连接，可调速电机201驱动伸缩杆202带动躯干支撑板203上下活动，模拟蛙泳躯干在水面上下起伏的换气动作。
下肢运动机构3，包括下肢轨道31、蹬腿滑块总成32、足部系留板33、钢丝绳34和下肢止位器35；蹬腿滑块总成32通过钢丝绳34柔性连接足部系留板33以释放蹬腿滑块总成32在下肢轨道31中滑动中产生的转动，和蹬腿滑块总成32与足部系留板33之间产生的转动差，蹬腿滑块总成32；在下肢收腿位置处，下肢轨道31设置下肢止位器35，下肢止位器35接收下肢止位器感应开关14的信号，通过或阻止蹬腿滑块总成32滑动，用于避免不适时机的收腿动作。
蹬腿滑块总成32包括一对同一轴线并行设置的导轮321、一对导轮连接板322、轴323、带轴承安装座的装衬垫件324和轴承325；导轮连接板322上间 隔设置上轴孔3221和下轴孔3222，一对导轮连接板322分别放置在一对同一轴线并行设置的导轮321的两侧，轴3231、3232分别通过导轮连接板322的上轴孔3221和贴近导轮连接板322的导轮321的中心轴孔进行连接；置于一对导轮连接板322之间的装衬垫件324上设置一通孔3241，轴3233通过一对导轮连接板322的下轴孔3222和通孔3241进行紧固连接。轴承325通过轴承安装座安装于装衬垫件324，轴承325连接钢丝绳34一端，钢丝绳34的另一端连接足部系留板33。下肢轨道31为与导轮321相配合的双导轨；所述双轨道之间焊接吊装片4，用以悬空吊装下肢轨道31，使所述足部系留板在所述下肢轨道的下方运动。
蛙泳配合动作要领：划手腿不动，收手再收腿，伸手再蹬腿，并拢伸直漂一会；换气动作：划水头部慢抬起，伸手滑行慢呼气；如图8。本实施例中，
蛙泳初学者在使用该设备时，双臂放在上肢轨道11的上方，双腿放在下肢轨道31的下方。手按压在翻动板124上，躯干由翘动板23或躯干支撑板203承托，脚系在足部系留板33上。
蛙泳初始准备动作：对应图8中的动作步骤1，双手臂伸直，双腿伸直。
划手腿不动：对应图8中的动作步骤2、3，步骤2是上肢划水状态起始位置，上肢向左右手臂的外侧划水，划水滑块总成12触发该位置的电机感应开关13，电机感应开关13发出信号控制驱动调速电机24、201带动翘动板23或躯干支撑板203缓缓向上运动，模拟蛙泳者由水面下向水面上抬头的准备吸气动作。此时，蹬腿滑块总成32处于自由状态。
收手再收腿：对应图8中的动作步骤4、5；步骤4是收手动作步骤，即上肢收手臂位置处，对应划水滑块总成12沿上肢轨道11运动至该位置，下肢止位器感应开关14发送信号控制常态为关闭状态的下肢止位器35打开。此时，对应步骤5，蹬腿滑块总成32通过设置有下肢止位器位置处的下肢轨道31，开始收腿，完成一次完整的收腿动作。如果上肢划水动作还未完全到步骤4的收 手动作，下肢止位器感应开关14无法控制下肢止位器35打开，蹬腿滑块总成32无法通过设置有下肢止位器35位置处的下肢轨道31，从而限制收腿动作，达到手臂和腿在动作时间的协调性。在上肢收手臂位置处，调速电机24、201带动翘动板23或躯干支撑板203缓缓向下运动，模拟蛙泳者躯干由水面上向水面下缓缓低头的准备呼气动作。伸手再蹬腿：对应图8中的动作步骤6、7，即划水滑块总成12沿上肢导轨11向正前方滑动，由于收手再收腿造成的时间差，从而再进行蹬腿滑块总成32滑动蹬腿动作。
并拢伸直漂一会：对应图8中的动作步骤8，双手臂伸直，双腿并拢，划水滑块总成12滑向最前方，蹬腿滑块总成32滑向最后方，使上肢与下肢伸直成一条线，漂浮一会。伸直手臂的位置，调速电机24、201停转，等待下次划水滑块总成12触发电机感应开关13，进行下一次划水动作。
上肢轨道11和下肢轨道31运动轨迹可根据三维软件建立蛙泳的手腕和脚腕的运动轨迹模型，经过运动仿真和实验最终确定轨道的形状。利用划水滑块总成12和蹬腿滑块总成32模拟实现手腕和脚腕划水和蹬腿的动作，保证泳姿动作的准确性。
在另一实施例中，配合上述陆上蛙泳学习机使用的增加训练时间装置4，包括吊装于所述躯干运动机构上方的偏心轮41和电机42，偏心轮41通过第五连接件43与训练者所带的头盔5连接，其中，第五连接件43可以为摇杆、绳索或索具等，电机42驱动偏心轮41与翘动板23或躯干支撑板203的起伏同步转动，也即偏心轮41和偏心轮25同步同转速完成训练者胸部及头部协调一致吊起上扬、放下及复位动作，以降低训练者胸部在所述躯干运动机构上的压力。
为了更加准确地完成吸气及呼气，在偏心轮旁安装一个感应开关及声音提示喇叭，对应在吸气及呼气时做出声音提示。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
