Description

重量训练滑车
本申请是申请日为2017年2月2日、申请号为201780021931.1(国际申请号PCT/US2017/016228)、发明名称为“重量训练滑车”的发明专利申请的分案申请。
背景技术
重量滑车已经成为室内健康和健身俱乐部中越来越受欢迎的锻炼设备,其中许多俱乐部具有有限的开放空间。重量滑车,也被称为阻挡滑车,通常在一个或多个滑板上支撑重物,该滑板对滑车的运动施加摩擦阻力。在美国专利申请公开2014/0073492中描绘了一种示例性传统重量滑车。重量滑车最初是为户外使用而设计的,其中极少关注空间和由于滑板抵抗地面的摩擦滑动造成的损坏。从室外到室内使用的转变带来了一些挑战,挑战包括需要大量的开放空间和能够承受滑板在地板上反复摩擦滑动的磨蚀效应的地板的安装结构。
在美国专利3,326,553(三轮滑移转向版本)和6,942,585(单轮版本)中描述了阻挡滑车的轮式版本,其中基本消除了摩擦打滑,但是其以推动滑车时的稳定性损失为代价,因此需要机载操作员来操纵美国专利3,326,553的滑车,或者需要额外的空间来适应美国专利6,942,585的滑车的不受控制的不稳定性。
因此,需要一种重量滑车,其设计成在狭窄的室内空间中安全无损地使用。
此外,传统的重量滑车在使用过程中倾向于向前倾斜,其中使用者将滑车的工作端部(即,由锻炼者接触的端部)抬离地面,从而导致牵引力下降。尽管期望某些有限的训练锻炼,例如需要施加提升力矢量的适当阻挡技术的教导,但这种牵引力的可变下降通常是不利的,因为它降低了滑车的阻力练习值。
因此,还需要一种重量滑车,其在正常和预期使用期间保持与地面完全且牢固地阻力接触。

构造
参考说明性附图,本发明涉及一种重量训练滑车100(下文称为“滑车”),其特征在于以下一项或多项:(A)可旋转轮130与地面接触,(B)弯曲的推动手柄140配置和布置成(i)在推动手柄140上提供手部握持部143的舒适且自然的间隔,(ii)提供在推动手柄140上的手部握持部143的相对于竖直方向的舒适且符合人体工程学的向内α度角,以及(iii)提供在推动手柄140上的手部握持部143的向下β度角,以便限制当使用者推动滑车100时所产生的向上力矢量的量,并且优选地配置和布置成产生向下力矢量以便防止或限制将滑车100的工作端部抬离地面,以及(C)牵引钩160安装在滑车100上以提供至少30cm的间隙,从而限制当使用者拉在牵引钩160处附接到滑车100的牵引绳(未示出)时所产生的向上力矢量的量,并且优选地配置和布置成产生向下力矢量以便防止或限制滑车100的牵引端部抬离地面。
轮式滑车
轮式滑车100包括底盘110、至少两个固定方向轮130、推动手柄对140和至少一个制动机构200。轮式滑车100优选地包括(i)四个固定方向轮130,其安装在轴对120上以便形成串轴四轮式重量训练滑车100,以及(ii)至少一个并且优选地两个重量板臂150。
轮式滑车100具有在纵向x上间隔开的第一端部101和第二端部102,以及在侧向y上间隔开的第一侧103和第二侧104。
图1至图5中描绘的优选的底盘110是金属结构,其具有在纵向x上为长形且在侧向y上间隔开的第一侧导轨117和第二侧导轨118,所述第一侧导轨117和第二侧导轨118通过横梁119刚性地互连,其限定具有第一纵向端部111和第二纵向端部112、第一侧面113和第二侧面114、以及横向顶部115和横向底部116的底盘110。
轮130是固定方向轮130,其可旋转地安装到底盘110以用于将底盘110的底部116支撑在表面上方一定距离(下文称为“间隙”)。至少两个轮130的固定方向和纵向间隔约束底盘110沿着基本线性的纵向x路径在表面上往复行进。
当采用两个轮130时,它们优选地在滑车100的正中矢状平面中在纵向x上对准。当采用三个轮130时,它们优选地在等腰三角形的角部处间隔开,其中两个轮130在滑车100的一个端部101附近在侧向y上对准,并且第三个轮在滑车100的另一端部102附近定位在中央。当采用四个轮130时,如图1至图5所示,轮130以在侧向y上间隔开的对131和132分别安装在两个在侧向y上延伸的轴121和122中的每一个轴上,其中轴121和122分别安装在滑车100的每个纵向端部101和102附近,以及在每个轮对131和132中的轮130安装在滑车100的相对的两侧103和104附近。四个轮的实施例通常是优选的,因为它提供了增强的稳定性、沿纵向x路径的增强的线性行程,并且便于沿着线性行进路径在两个方向上进行锻炼。或者,四个轮的实施例可以采用一对在滑车100的纵向端部101和102附近在纵向x上对准且在侧向y上居中的轮130,在竖向z上抬升或在竖向z上对准的支轮(outrigger wheel)130从滑车100的每侧103和104延伸。
轮130优选地是充气轮130,其具有良好牵引力以便在锻炼期间限制与轮130的期望旋转相反的不期望的轮130在地板上的滑动。
至少一对在侧向y上间隔开的推动手柄140靠近推动手柄140的近端140p附接,靠近底盘110的一个端部111或112以便由使用者握持以推动滑车100。如图1至图5所示,滑车100优选地包括两对推动手柄141和142,其中第一对推动手柄141固定到底盘侧导轨117和118的第一端部117a和118a,第二对推动手柄142固定到底盘侧导轨117和118的第二端部117b和118b。这允许使用者通过沿纵向x行进路径在任一方向上推动滑车来进行锻炼。
一个或多个重量板臂150可以设置在底盘110上以用于将重量板(未示出)安装到底盘110的顶部115上,从而增加由滑车100提供的锻炼阻力,更重要的是,抵消由使用者施加的任何向上提升力矢量,该向上提升力矢量将倾向于抬起滑车100的一个端部从而将离使用者最近的轮130抬离地板。如图1至图5所描绘的,优选实施例具有沿着滑车100的正中矢状平面定位的第一重量板臂151和第二重量板臂152,每个重量板臂固定到靠近底盘110的每个端部111和112的横梁119。橡胶缓冲器153可以靠近每个臂151和152设置在底盘115的顶部上,以用于在将重量板添加到臂150或从臂150移除重量板时缓冲和保护底盘110。
通常参考图1至图5,制动机构200附接到底盘110并与至少一个轮130连通,优选地与安装在同一轴120上的轮对130连通,以用于沿纵向x行进路径施加抵抗轮130的旋转的双向控制可变阻力。可以为每个轮130或每个轴120提供单独的制动机构201和202,并且当滑车100在每个端部101和102处设计有用于双向阻力行程的推动手柄140时这是优选的。已知许多类型的阻力设备,诸如制动马达、发电机、无刷发电机、涡流系统、磁系统、交流发电机、可紧带、摩擦辊、流体制动器等,其中任何一种都可以有效地用于本发明。通常优选能够基于行进的加速度或速度提供渐进阻力的制动机构。
更详细地并且参考图6,优选的制动机构200是涡流制动器200,其安装到底盘110的第一侧导轨117以用于对第一轴121的旋转施加阻力。在图6中以完全组装的状态描绘并且在图6A至图6D中逐个组件地描绘的涡流制动器200包括:(i)安装板210,其刚性地附接到底盘110(图5),(ii)驱动链轮220,其可与第一轴121的一部分一起旋转并固定到其上,第一轴延伸穿过安装板210中的孔211(图6),(iii)滑轮组件230(图6A),具有滑轮234和从动链轮233,所述滑轮234和从动链轮233经由内部轮毂231和链轮安装件232可旋转地安装到从安装板210突出的第一安装柱212上,经由驱动链239与驱动链轮220可旋转地驱动连通(图6),(iv)涡盘组件240,其包括涡盘242,涡盘经由具有轴241’和安装板241”的盘安装件241可旋转地安装到从安装板210突出的第二安装柱213上,经由驱动带249与滑轮组件230可旋转地驱动连通(图6C),(v)驱动带张紧组件250,其固定在安装板210中的调节狭槽214内以用于可调节地张紧驱动带249(图6B),以及(vi)磁性定子组件260,其固定到安装板210以用于手动(如图所示)或自动(未示出)地经由如图6D所示的安装板210中的调节狭槽215或如图7所示的多止动杆265相对于涡盘组件240的涡盘242重新定位磁体261,从而根据需要增加或减少阻力。
在优选实施例中,制动机构200可调节成中性阻力设置,由此滑车100有效地从锻炼滑车转换成运输车。空档设置便于滑车100从一个位置移动到另一个位置,诸如在存储位置和使用位置之间来回运输。当处于中性阻力设置并且配备有可移除的筐时,滑车100有效地用于将物品(诸如待被用于锻炼的附加锻炼设备)从一个位置运输到另一个位置。空档设置优选地对轮的旋转施加一些适度的阻力,其不会明显地干扰滑车100的运输,但是对于防止或至少减慢重力引起的滑车100的运动是有效的。
可以在每个制动机构201和202的组件上提供保护护罩270。
弯曲的推动手柄
参考图8至图11,每对在侧向y上间隔开的推动手柄140优选地是弯曲的以便提供:(A)握持部143,其靠近推动手柄140的远端140d,朝向彼此向内成角α并且朝向底盘110向下成角β,和/或(B)在成对的推动手柄140的轴向中心之间在侧向y上延伸的间隙149,所述间隙在侧向y上的宽度沿着成对的推动手柄140的更靠近底盘110的第一长度1481增加,并且沿着成对的推动手柄140的远离底盘110的第二长度1482减小,从而在第一长度1481内在成对的推动手柄140之间限定最大间隙1491以及在第二长度1482内在成对的推动手柄140之间限定最小间隙1492
握持部143的向内成角α提供了更自然的符合人体工程学的旋转握持位置,而握持部143的向下成角β使得当使用者正在由向上指向的力矢量推动滑车100时所产生的竖向力矢量中的至少一些力矢量重新定向成向下指向的力矢量,从而防止或至少限制滑车100的工作端部抬离地面。
握持部143均优选地具有至少10°的向内成角α,其优选地在15°和30°之间,以及至少10°的向下成角β,其优选地在15°和30°之间。
每个成对设置的推动手柄140的曲状角优选地提供间隙149的在侧向y上的宽度的从最小宽度1492到最大宽度1491的至少20%的变化(例如,对于20cm的最小宽度1492,最大宽度1491至少为24厘米)。间隙149的在侧向y上的宽度的这种变化优选地在20%和40%之间。
此种弯曲的推动手柄140适用于大多数类型的锻炼滑车100,包括骑行在滑板530上的典型的摩擦滑车和本文所述的轮式滑车。
升高的牵引绳钩
参考图8至图10,在侧向y上间隔开的推动手柄140的每对推动手柄141和142可以通过横向构件145互连,横向构件位于底盘110上方的一纵向x距离处。该横向构件145提供成对的推动手柄140的稳定性和用于将牵引绳(未示出)附接到滑车100的升高位置这两者。牵引钩160优选地从每个横向构件145的在侧向y上中心向外纵向x延伸,以便于牵引绳(未示出)的临时附接。横向构件145,特别是当定位在成对的推动手柄140的非常远端140d时,可以由推动滑车100的使用者握持以作为替代的握持位置。
横向构件145并且由此牵引钩160优选地定位成使得在牵引钩160和地面之间提供至少30cm的间隙。牵引钩160的此种升高的定位用于限制当使用者牵拉在牵引钩160处附接到滑车100的牵引绳(未示出)时产生的向上力矢量的量,从而限制并可能消除滑车100的牵引端部抬离地面。
尺寸
下面提供对滑车100的值和/或性能具有某些意义的各种可接受的、优选的和最优选的尺寸。

使用
可以通过以下步骤方便且安全地在小至1.2米宽和5米长的狭窄空间中使用滑车100:(i)将制动机构200设定至所需的阻力,(ii)站立在滑车100的第一端部101,(iii)向前倾斜并握持第一对推动手柄141,(iv)沿纵向路径在第一纵向x方向上推动滑车100,(v)围绕滑车100行走至滑车100的第二端部102,(vi)向前倾斜并握持第二对推动手柄142,(vii)沿着纵向路径在第二纵向x方向上往回推动滑车100,(viii)围绕滑车100往回行走至滑车100的第一端部101,以及(ix)根据需要多次重复步骤(iii)-(viii)。
