Abstract

一种跨步锻炼设备，包括具有两条以一不变的半径弧向上弯曲的延伸平行的轨道和两块可旋转地支撑在轨道上并在其上作往复运动的脚踏板。半径弧一般是相应于当人腿绕臀部旋转时腿的自然摆动弧。当操作者站在脚踏板上，沿着向上弯曲的轨道，向后和向前往复运动脚踏板时，操作者的躯体在底架上保持在一个稳定和平衡的位置。在躯体运动上的减少实际上消除了由于躯体向上和向下运动引起的在腿关节，特别是膝和臀关节上的应变，另外基本上消除了由于在腰达到了所限程度和弯曲引起的应变。

Description

具有向上弯曲轨道的跨步锻练器
本发明涉及一种锻练器，特别是一种具有模拟自然走路的跨步锻练器。
走路，缓步和越野滑雪已经被发现为锻练身体的有效活动，特别是对于腿、听力和呼吸器官。然而，这些活动主要是户外活动，受到了不利天气和地理条件的严重限制，这些传统的户外活动所受到的限制在某些方面已经通过发展模拟特殊锻练活动的室内锻练设备而得到消除。关于这一点，走路，跨步和越野滑雪设备的多种变型在现有技术中是已知的。就这点而论，Dalebout的美国专利No.4850585；Hix的No.4654200；Bull等的No.4940233和Friedebach的No.4804178是特别与本发明有关的。
Friedebach的专利公开了一种越野滑雪设备，它包括一对平行的水平轨道及一对活动地支撑在轨道上的脚踏板。Friedebach的越野滑雪设备进一步包括一带状机构，它能使脚踏板在相反的方向上协调一致的运动。另外，该滑雪设备包括两个独立的手持杆，它向后和向前旋转以模拟滑雪杆的运动。在使用中，操作者站在脚踏板上，当同时推拉手持杆时，脚踏板来回摆动。Friedebach的越野滑雪设备可以提供有意义的需氧锻练，业已发现在操作者的背部和腿关节承受了很大的应力。脚沿着水平轨道往复运动引操作者的躯干向上和向下运动，使得每一跨步时，操作者连续地升起他或她的体重。同时，躯干的上下抬升运动增加了在腿关节上的应力，特别是臀和膝关节的应力。更进一步，手持杆的推拉迫使操作者向上弯曲从腰到达不必受力的背部肌肉。因此，具有背部、膝或臀部问题的人常常发现它不舒服，费力或甚至不可能去应用雪撬型的锻练机。
Dalebout，Hix和Bull等的专利公开了一种设备，它们通常被认为是作为跨步型的锻练器，典型的跨步型锻练器包括一对彼此隔开的垂直框架部件和一对枢轴地安装在垂直框架部件上的摇摆腿部件。在使用中，操作者站在安装于摇摆腿部件端部的平台上，在垂直框架部件之间摇摆运动时，他或她的腿作往后和向前的往复运动。在跨步型锻练器中，腿的摇摆运动提供了与Friedebach越野滑雪锻练器大体相同的需氧有利条件；然而，跨步锻练器使得使用者在一个更稳定的位置下平衡，减少操作者的躯体向上和向下运动及减少在背部和腿关节的过分疲劳。当跨步型锻练器包括手持杆时，杆通常是绕一个点旋转，不要求操作者在运动中弯曲或伸手。虽然跨步锻练器已被发现在提供低应力需氧锻练上是很有效的，但它们存在了几种设计问题，因而阻止了它们的广泛销售及使用。跨步锻练装置一般要求比较强的框架部件和比较强的轴承以适应在枢轴机构上的操作者的重量。结果，这些机构对在家庭使用来说体积太大和太重了。
而且，重的结构使得跨步锻练器在同其他不贵的锻练设备的竞争中显得太昂贵。因此，跨步锻练器通常仅在公共康复中心才能找到，大尺寸锻练设备需具有相当大的资金以购买和维修这些机器。另外，已经发现在现有技术跨步锻练器的设计中，跨步型锻练器的垂直框架部件阻止锻练者从侧边位置进行安装，从而产生了安全危险问题现有的跨步锻练器设计成操作者必须从后部安装机器。当操作者第一步踏在平台上，平台就趋向于向前旋转，在以相对的脚向上踏之前，操作者失去平衡。所以，可以看出不熟练的操作者安装机器时可以被扔离平衡状态，跌到地板上。
本发明提供一个新颖的和便宜的跨步型锻练器，它克服了现有技术的一些缺点。简单地说，本跨步锻练器包括一个底架，该底架具有一对伸长的平行轨道，轨道以一连续的弧度向上弯曲，还包括一对可旋转地被支撑在向上弯曲轨道上的脚踏板，以便作往复运动，以及一个用来使脚踏板在相反方向上协调运动的滑轮机构。轨道向上的弯度一般是相应于人腿自然摆动的弧度，以便当操作者站在踏板上，在轨道上来回往复运动时，操作者的驱体在底架上保持在一个稳定和平衡的位置。
本发明的一个目的是提供一种模拟自然走路的锻练设备。
本发明的另一个目的是提供一种锻练设备，它调节使用者的心血管系统，没有与传统的锻练机相关联的肌肉和关节扭伤。
本发明的另一目的是提供一种跨步锻练器，具有向上弯曲轨道的底架，轨道弯曲与腿自然摆动弧度相一致。
本发明的另一目的是提供一种跨步锻练器，能使使用者的驱体保持在轨道上的一个稳定和平衡的位置。
本发明的进一步的目的是提供一种跨步锻练器，它设计是简单的，结构是容易的以及制造成本是不贵的。
结合说明书附图来考虑，说明书所表明的另外的发明目的，特征和本发明的优点将变得更加明显。
在附图中，说明了为实现本发明的最好方式：
图1是本发明跨步锻练器的透视图；
图2是用于说明本发明目的而带有底架覆盖物及移去手持柄的顶透图；
图3是它的前视图；
图4是图1中的线4-4的横截面图；
图5是图1线5-5的横截面图；
图6是本锻练设备的第二个实施例的透视图。
现在参照附图对本发明的跨步锻练器作说明，在图1-5中用10表示该锻练器。在下文将作更完整描述。本发明提供一种便宜的跨步锻练器10，它在有氧地状态下调节操作者的心血管系统，没有通常与传统的锻练机相联系的肌肉和关节应力。跨步锻练器10一般包括以12表示的弯曲的底架，以14表示的可活动地支持在底架12上的两个踏板，以及以16表示(图12)的滑轮装置，它可以使脚踏板14在相反方向上协调一致的运动。更明确地说，底架12包括一个完整成形的吹模体，它有靠模底边18，为了把底架12支撑在一个平面上的有间隔的腿19和一靠模上边20。靠模上边20包括两条伸长的平行的轨道22，它以一连续的弧度向上弯曲。轨道向上弯曲的程度一般相应于人腿绕其臀部关节旋转时自然摆动弧度。在这方面，轨道更可取的是采用一不变的半径的弧度，然而，如果希望的话，可以稍微的不圆。轨道22的每一个包括中央脊24和两条在脊24每边的有间隔的槽沟26，脊24适合于支撑脚踏板14(见图5)。靠模上边20进一步包括一延伸的中央脊27(也见图5)，它在两个轨道22之间延伸。把底架12作为一个完整的成形部件在这里作专门描述，很明显底架12也可以由管状金属元件来建造，在那里，向上弯曲的轨道是由平行的铁轨来成形的。
脚踏板14一般是U形(图5)的，它包括一水平的板架28，供操作者的脚踏在其上，两个向下延伸的板腿30和四个可旋转地安装在板腿30的滑轮32。脚踏板14的板架28放在各自轨道22的中央脊24上，使得轮32骑在脊24两边的有间隔的槽沟26内。因此，可以看出脚踏板14能沿着轨道22的长度方向来回运动。
滑轮机构16被固定于两个脚踏板14上，在使用中，它能使踏板在相反方向上协调一致地运动。滑轮机构16包括两个滑轮34，它们分别安装在中央脊26的前后端所形成的凹地内，绳索以38(图2)表示，它被固定于脚踏板14并绕滑轮34延伸以形成一连续回路。更明确地说，附于脚踏板14之一后端的第一绳带部分40，绕后滑轮34延伸并附到另一踏板14的后端。同样，附于第一踏板14前端的第二绳带部分42绕前滑轮34延伸并附到另一踏板14的前端。所以，可以看到，当踏板14之一在它的轨道内向前运动时，另一踏板14在它的轨道内向后运动。为了从视觉上隐蔽滑轮34和绳带部分40及42，并防止在使用中操作者的脚被绳带40和42缠住，底架12用覆盖物44盖住，覆盖物放松地安装在中央脊26上面。覆盖物44也保留有绳带40和42，以致它们与底架12的弯曲形状相一致。
跨步锻练器10进一步包括用46表示的一副手柄杆，它们连接到底架12的前端。手柄杆46包括两根向下延伸的臂48，它们是可旋转地与底架12的侧边相连，一水平的杆体50用来支持一个电显示装置52是有效的。延伸臂48的枢轴连接使得手柄杆能向下旋转，结果，整个锻练设备10可以更容易地被运输和贮藏。为了保持手柄杆46处在一个稳定和垂直的位置，底架12的侧边包括两处三角形凹槽53，它们对于接受安装到延伸臂48的环形支持件54是有效的。手柄杆46的臂杆48进一步包括橡胶或泡沫衬垫作成的手柄56，用于使操作者在使用过程中握紧。电显示装置52对于测量时间，卡路里或与设备10使用有关的其它情报是有效的。
在使用中，操作者站在脚踏板14上，紧握住手柄杆46上的橡胶衬垫手柄56，并沿着向上弯曲的轨道22来回运动踏板。因为手柄杆46能在使用中帮助保持平衡，现已发现，本跨步锻练器10对站在底架上的使用者有很好的平衡作用以致在使用过程中使用手柄杆46实在是没有必要。就此而论，为了增加这种锻练的有氧益处，当走路时，操作者可以象平常一样摆动他们的臂，从而，利用了手的重量。轨道22向上弯度应适应于操作者腿的自然摇摆弧度，保持操作者的驱体处于底架12上的稳定和平衡位置。弯曲的轨道22使操作者的腿自然地绕他们的臀关节旋转，不要求每一次跨步腿向上带动身体或驱体。因为不要求操作者连续地抬起腿，所以实际上在腿关节，特别是踝，膝和臀关节没有应力。另外，躯体的稳定位置实际上消除了传统的越野滑雪机通常与反复弯曲和反复伸手相联系的背部应变。这种混合的影响在实际上消除了操作者背部和腿的身体应力，提供了一个有效的有氧锻练。同时要指出，本跨步锻练器10为了平衡他们的重量允许使用者从一边到那边进行安装，结果，当安装设备10时，脚踏板不向前和向后滑。
跨步锻练器的第二个实施例是，由图6的58表示。在第二个实施例58中，手柄杆46被两根可转动的手持杆60代替。手持杆60借助可旋转联接器(未表示出来)安装到底架12的侧边，它们具有为调节手持杆60的运动阻力强度的常规的阻力装置。手持杆60提供一装置用于在锻练器10使用过程中同时使身体向上。操作者简单地紧握手持杆60，在与脚踏板14相反方向往复摇动它们。为了在第二个实施例58中支撑电显示装置52，锻练器10提供了一根柱状支撑62，它固定于底架12的前部。
因此，可以看出，本发明提供一个十分不寻常的和有效的跨步锻练器用以锻练操作者心血管系统，没有通常与常规锻练设备相联系的肌肉和关节应力。轨道22的向上弯曲半径有效地保持操作者的驱体在底架12上面的稳定和平衡位置，因此减少背部和腿部的应变。而且，本跨步锻练器允许侧面进行安装比现有技术后部安装更容易和更可靠。进一步说，本锻练设备10制造价格便宜，操作简单和有趣，而且它可折叠便于运输和贮藏，这些值得注意的特点是现有的锻练设备所没有呈现出来的。对于这些理由，本发明代表了该技术领域的重要发展，有重大的商业价值。
在这里所表示和描述的是具体体现本发明的某些特定结构，对于该技术领域来说是明显的，在不违背本发明的根本概念的精神和范围内可作各种部分的变型和安排，对于这里所表示和描述的特定形式同样是不受限的，除了用Y表示附属权利要求范围之外。
