牵拉角自调节环形绳索训练器10
参考图1、2、7、8和13，本发明是一种环形绳索训练器10，其包括直立框架100、动态头部组件200、阻力组件240和环形绳索260。动态头部组件200自旋转以保持动态头部组件200中的辊(未被总体编号)与环形绳索260的牵引角的适当对准。
参考图1、2、7和8，直立框架100包括与地面接触的纵向x和侧向y延伸的基座102、横向z/竖直延伸的支柱104、和优选地纵向x/水平延伸的吊杆106。
动态头部组件200在地面上方一段距离处被支撑在框架100上，优选地在横向z高度处，所述高度将动态头部组件200的驱动轴线245定位在地面上方至少8英尺处。
参考图5、6、11、12、13和14-27，动态头部组件200包括辊组件210，所述辊组件210具有(i)驱动辊211，(ii)松弛侧引导辊212，它用于将进入的环形绳索260引导到驱动辊211上，和(iii)张紧侧引导辊213，它用于在环形绳索260脱离驱动辊211时引导环形绳索260。
驱动辊211键接到侧向y延伸的驱动轴244以便绕侧向y延伸的驱动轴线245旋转。驱动辊211优选地具有在驱动辊211的轴向中间平面处测量的3英寸和12英寸之间的直径。
引导辊212和213彼此纵向x间隔固定距离以在引导辊212和213的最外圆周225之间限定固定距离的纵向x间隙229。这个纵向间隙229优选地小于在驱动辊211的轴向中间平面处测量的驱动辊211的直径，并且最优选地被设计尺寸用来提供并保持环形绳索260在驱动辊211上的至少200°的接触包角α。
参考图4、10和13，引导辊212和213被构造且布置用来独立于驱动辊211绕驱动轴244的驱动轴线245作为一个单元一起枢转。更具体地，引导辊212和213安装到辊组件外壳227，而辊组件外壳227以可旋转的方式安装在驱动轴244上以便绕驱动轴线245旋转且绕驱动辊211旋转。引导辊212和213可以静态地或以可旋转的方式安装到辊组件外壳227。
将图1-图6(被垂直拉动)与图7-图12(以倾斜角度被拉动)比较，相对于竖直方向以倾斜的角度向下拉动环形绳索260实现所述一对引导辊212和213绕驱动轴244的驱动轴线245以与所述倾斜角度相称的角度枢转。所述一对引导辊212和213绕驱动轴244的驱动轴线245以与所述倾斜角度相称的角度的这种枢转保持环形绳索260在驱动辊211上的恒定接触包角α，即使当相对于竖直方向的所述倾斜角度大于10°时。
参考图1、2、7、8、14和15，环形绳索260被夹带或卷绕在驱动辊211周围，自由端部261被布置成靠近地面并且限定松弛侧262和张紧侧263，松弛侧262在使用期间向着驱动辊211返回，张紧侧263在使用期间被锻炼者拉离驱动辊211。自由端部261可以通过布置在地面附近的偏置滑轮(未示出)被置于恒定张力下，或者被允许从动态头部组件200自由悬挂。
参考图13、16、20、24和26，制动机构242对驱动轴244的旋转施加阻力，并且因此对驱动辊211施加阻力。可以使用用来提供这种阻力的各种熟知装置的任何装置，特别地但不排他地包括制动电机、发电机、无刷发电机、涡流系统、磁系统、交流发电机、紧固带、摩擦辊、流体制动器等等。能够基于加速度或行进速度提供渐进的阻力的制动机构242通常是优选的。
制动机构242被固定到并且保持在阻力组件外壳247内，所述阻力组件外壳静态地附接到框架100。驱动轴244以可旋转的方式安装在阻力组件外壳247上并且延伸穿过阻力组件外壳247以便绕驱动轴线245旋转。
环形绳索训练器10优选地包括阻力调节机构250，所述阻力调节机构用于调节施加到驱动辊211的旋转的阻力的水平。参考图1、2、3、4、7、8、9、10、13、14、15、18和19，合适的阻力调节机构250的一个实施例包括杆251，所述杆可操作以旋转入多个枢轴位置中的一个，以便与制动机构242相互作用，以增加或减小阻力。牵拉链252可以附接到杆251的远端部。
