Abstract

用于躺椅的机动化的倾斜机构允许将椅子置于零重力位置。底架包括2个相对于彼此枢转的子框架，以提供简易的倾斜机构。

Description

机动化的零重力椅子
技术领域
本发明涉及机动化的躺椅，具体涉及可以放置在零重力位置的椅子。
背景技术
机动化的躺椅是众所周知的，每月生产数万把椅子。通常，椅子将具有两个驱动机构，第一个驱动机构用于使椅子靠背倾斜，第二个驱动机构用于使脚凳伸出。这些机构还可以与座位底部相互作用，以提供较小的倾斜度变化。这种机动化的椅子已经在世界各地的家庭中得到广泛接受，并且尤其受到老年人或体弱者、特别是患病人士的青睐。类似的具有使靠背相对于底座独立地倾斜的另外的驱动机构的椅子也很流行用于肥胖治疗用途。
可移动到心脏休息位置或特伦德伦伯位置——在该位置，腿被抬高至与心脏平齐或高于心脏——的零重力椅子被广泛用于临床甚至家庭情况中，以减轻腿部中的血液滞积并改善或增加血液/流体循环。通常，这种椅子的家用版本是手动操作的，其中机动化的操作仅限于大型、昂贵和笨重的临床椅子。
希望将零重力特征结合到家用的机动化躺椅中以使大量的老年人、体弱者或肥胖人士受益。这样的椅子的已知示例通常使椅子相对于单独的底架倾斜，如此引起不必要地复杂，因此对于大众来说是昂贵并且难以企及的。
本发明的目的在于提供一种机动化躺椅，其具有简单的倾斜功能以减轻上述问题，或者至少为公众提供一种有用的替代方案。
发明内容
在第一方面，本发明提供了一种用于椅子的倾斜机构，其包括与地面接触并连接到椅子的靠背、座位和脚凳的第一子框架，以及与地面接触并枢转地连接到第一子框架的第二子框架，其中第一子框架和第二子框架相对于彼此的枢转使得实现椅子的靠背、座位和脚凳的倾斜。
优选地，第一子框架和第二子框架经由轮子与地面接触。
优选而言，第一子框架和第二子框架通过驱动连接在第一子框架与第二子框架之间的线性致动器的电动机相对于彼此枢转，并且椅子的靠背、座位和脚凳的倾斜将椅子置于零重力位置。
椅子可以是老人椅或肥胖者椅。
应当注意，上述任何一个方面可以包括任何上述其它方面的任何特征，并且可以适当地包括任何以下描述的实施例的任何特征。
附图说明
本发明的优选特征、实施例和变型可以从下面的详细说明中分辨，该详细说明为本领域技术人员提供了足够的信息以执行本发明。该详细描述不应被视为以任何方式限制前面的发明内容的范围。详细说明将参考如下多个附图。
图1A和1B示出了处于中间位置的结合了本发明的躺椅的透视图和侧视图。
图2A和2B示出了处于倾斜位置的结合了本发明的躺椅的透视图和侧视图。
图3A和3B示出了处于中间位置的本发明的倾斜机构的透视图和侧视图。
图4A和4B示出了处于倾斜位置的本发明的倾斜机构的透视图和侧视图。
附图部件
附图包括以下附图标记：
10 躺椅
12 靠背
14 座位
16 脚凳
20 底架
30 后子框架
32 后轮
40 前子框架
42 前轮
50 驱动机构

具体实施方式
本发明的以下详细描述参照了附图。在全部附图和以下描述中，将尽可能使用相同的附图标记来指代相同和相似的部件。为了清楚或说明的目的，附图所示的某些部件的尺寸可能已被修改和/或放大。
本发明提供了一种用于躺椅的简易机动化倾斜机构，其允许将躺椅放置在零重力位置。与使椅子的主体相对于底架枢转的已知机构不同，本发明提供了一种底架，该底架包括相对于彼此枢转的2个子框架，从而为典型的老人椅和肥胖者椅提供了简易的倾斜机构。
图1A和1B示出了处于中间位置的结合了本发明的躺椅10的透视图和侧视图。图2A和2B是处于倾斜位置的结合了本发明的同一把椅子。椅子的靠背12、座位14和脚凳16用虚线示出以揭示内部机构。这些附图并非旨在提供该机构的细节，而是传达了如何将本发明结合到本领域技术人员应认识的典型的机动化躺椅机构中。所示的机构的现有技术部分通常用于老人椅，并且可以具有一个或两个驱动电机以及相关联的连杆机构，以实现倾斜和脚凳伸展功能。本发明同样针对肥胖者椅，该肥胖者椅通常具有另外的电机以独立地使椅子的靠背倾斜。本发明包括底架20，该底架20包括后子框架和前子框架以及使子框架相对于彼此枢转并因此实现倾斜功能的驱动机构。始于图1A中的中间位置，脚凳16首先伸展，然后靠背12、座位14和脚凳16联动(in unison)倾斜以获得零重力位置。
在图3A和3B的透视图和侧视图中，本发明的机构被单独示出处于中间位置。该机构是包括可枢转地连接到前子框架40的后子框架30的框架20以及用于使子框架相对于彼此枢转的驱动机构50。各种几何形状可以用于框架。优选地，子框架是由管状钢或扁钢制成的简单矩形件，其中一个子框架比另一个子框架窄，使得它们可以嵌套在一起。在该优选实施例中，前子框架40比后子框架30窄，并且两个框架的侧轨沿着它们的侧面部分地枢转连接。后轮32安装在后子框架上，而前轮42安装在前子框架上。在图3A和3B所示的中间位置，两个子框架位于同一平面中，以提供可将其余椅子部件安装到其上的水平底座。大部分椅子部件——即靠背、座位和脚凳以及相关的硬件和驱动机构——直接或通过各种支架间接地安装到后子框架30上，其中椅子的座位与后子框架基本平行，使得当后子框架相对于前子框架旋转时，这些椅子部件与后子框架一起移动以实现倾斜位置。将大部分椅子部件有效地连接到后子框架并使前子框架旋转的布置结构同样适用于老人椅或肥胖者椅的内部。
图4A和4B分别单独示出了处于倾斜位置的本发明的机构的透视图和侧视图。通过使前子框架40和后子框架30围绕它们的相互枢转点旋转来实现倾斜。用于倾斜的动力由驱动机构50提供，该驱动机构包括电动机52和线性致动器54。该驱动机构作用在后子框架的横向构件与前子框架的横向构件之间，要么将它们拉在一起，要么将它们推开，以实现子框架的旋转并从而实现座位的倾斜。倾斜依赖于子框架既接触地面又随着子框架枢转，接触点相对于彼此移动。轮子32和42最佳地促进了这种移动。轮子可以是传统的轮子、脚轮或滚轮；甚至可以代之以在任一端或两端使用子框架的低摩擦端。轮子是优选的，因为它们还允许椅子易于移动。
现在，读者将理解本发明，本发明提供了一种用于使躺椅倾斜以实现零重力位置的简易机构。
在不脱离本发明范围的情况下，可以很好地对本发明实现进一步的优点和改进。尽管已经以被认为是最实用和优选的实施例示出和描述了本发明，但是应该认识到，在本发明的范围内可以与本发明有所不同，其不限于本文公开的细节，而是包括在权利要求书的全部范围内，以包括任何和所有等效的装置和设备。在说明书全文中对现有技术的任何讨论决不应该被认为是承认这种现有技术是众所周知的或形成了该领域中的公知常识的一部分。
在本说明书和权利要求书中(如果有的话)，用词“包括”及其派生词——包括“包含”和“具有”——包括每个述及的整数，但是不排除包括一个或多个其它整数。
