Description
技术领域
本发明涉及一用于移动家具件等的自定向的脚轮。
背景技术
已知的自定向的脚轮,尤其是所谓的双轮型的脚轮,由安装成两轮可围绕一轴转动的两个轮子构成。该轴被支承在一轴座内,轴座形成在位于两轮之间的一支承结构内,支承结构通常包括一种半圆柱形的外壳,它在一上部区域内覆盖住轮子。
一垂直的圆柱形凹陷形成在支承结构内,其向上敞开并相对于轴偏移,对于脚轮的自定向(枢转)其为垂直的枢轴起作一转动座,它设计成插入和保持在轮子所配装在其上的家具件的座内。
所述类型的自定向脚轮具有的缺点在于,用于脚轮的自定向的枢轴经常可造成过分的和不愉快的噪音,特别是当脚轮滚过一粗糙的地面或如果用来接纳枢轴的家具件的座是形成在一金属体内。这在椅子或扶手椅子中可特别地看到,它们设置有带有径向臂的金属底座,其中,脚轮配装在臂的端部处。由于底座的对应的凹陷内的枢轴具有不可避免的游隙,这种缺点甚至存在于新式的脚轮中,当这种游隙由于使用而趋于必然的增大时,这种缺点就变得严重起来。
发明内容
本发明的目的是避免现有技术的自定向脚轮中存在的上述的缺点,通过提供一简单和有效的解决方案来实现该目的,该方案对目前市场上出售的脚轮的结构不需作大的变化,因此,经济上具有优点。
该目的用一自定向的脚轮来实现,它由至少一个可在轴上转动的轮构成,该轮通过一设置有一垂直的圆柱形凹陷的支承的座被水平地驱动,该凹陷向上敞开并相对于轴沿轴向偏移,其中,脚轮的枢转枢轴可随第一部分转动,并设置有一可插入在配装脚轮的家具件的一座内的第二部分,其中,所述第二部分具有一直径减小的端部杆以便形成一台肩,一轴套沿轴向固定在所述杆上,并与所述台肩一起形成一环形槽,其用来没有轴向游隙地容纳一弹性环,通过扩展该弹性环适于压靠在所述凹陷的壁上。
附图的简要说明
从以下对脚轮的优选的但不排外的实施例的详细的描述,本发明的其它的特征和优点将会变得更加明白,脚轮借助于附图中的非限制的实例示出,其中:
图1是设置有根据本发明的创新的自定向双轮型脚轮的立体图;
图2是图1的脚轮的侧视图;
图3是图1的脚轮的前视图;
图4是图1的脚轮的平面图;
图5是用于脚轮枢转的枢轴的视图;
图6是图5的枢轴的分解的视图;
图7是图5的枢轴的截面图;
图8是图5的枢轴的轴向视图;
图9是根据另一实施例的枢轴的立体图;
图10是图9的枢轴的分解的视图;
图11是枢轴的端部的截面图。
具体实施方式
参照图1至8,标号1一般地表示一自定向型的普通双轮脚轮,它包括一用于两个轮子3的支承结构2,轮子安装成可在公共轴S上转动,轴S具有一水平轴线A并通过结构2的座被驱动。
结构2由塑料或金属材料制成,它具有一凹陷4,凹陷具有一垂直轴线,位于两个轮子3之间,并容纳一枢轴5,借助于枢轴5脚轮可枢转地配装在家具件上,例如,一设置有带有径向臂的底座的椅子,在其端部处设置有用于配装脚轮的座。
如图5至8中更为清晰地所示,用来枢转脚轮的枢轴5结构上呈圆柱形,并包括一下部6和一上部7,它们通过一环形的突缘8彼此分离。一环形槽9设置在下部6内,而一锥形内腔10设置在下部6的端部内。
下部6插入在凹陷4内,其中,为了轴向地保持枢轴5,设置有一内部的轴环,它通过加力而与槽9接合。一钢球(未示出)方便地布置在凹陷4的底部,并通过在内腔10内的接合,对承载在脚轮上的载荷起作一支承点。
枢轴5的上部7包括一靠近环形突缘8的锥形连接区域11,它朝向所述突缘展开,以及一直径减小的区域,它形成一端部杆12。端部杆12通过一台肩13与上部7的其余部分分离。此外,一盲孔14沿轴向形成在杆12的自由端,并被环形唇形物15所包围。
一由塑料材料制成的轴套16施加到杆12,其长度应这样:一旦它布置在杆12上,则连同台肩13一起形成一环形槽17。一敞开的和弹性的(即,弹性地扩展)的金属环18布置在槽17内,它具有一圆形截面,在扩展的状态下具有的外直径略微地大于上部7的直径,而一内直径至少等于杆12的直径。
环18通过轴套16锁定在槽17内,轴套16又通过一环形突脊保持在杆12上,突脊通过向外折叠唇形物15而获得。轴套16带有略微的过盈施加到杆12,其位置设定为:环18在槽内没有轴向的游隙,但当所述枢轴插入家具(椅子)件的座内时,环同时能沿径向闭合在枢轴上。
有利地是,通过由唇形物15实施的固定作用,有助于轴套16锁定在杆12上,这样,即使在伸展的使用中和更加不利的操作条件中,也能确保脚轮噪音减小的效果。
应该指出的是,环18的减小噪音的作用发生在径向和轴向。一旦枢轴5已经插入其在家具(椅子)件的座内,借助于环的较大的径向直径,环18压靠在所述座的壁上,这样,与借助于脚轮从枢轴传输到底座的横向振动相对立。同时,这也是本发明理念的基本优势,借助于沿轴向施加在环18上的锁定作用(它由抵靠台肩13的唇形物15锁定),轴套16防止其任何轴向的运动,因此,防止振动的发生。
在其实用的实施例中,本发明易于作出多种改型和变体,所有的改型和变体均在该发明理念的范围之内。因此,例如,弹性环18可具有一方形、长方形或椭圆形的截面。有利地是,弹性环18具有彼此轴向偏移的相对端(它们形成其间隙),这样,一旦环已经插入槽17内,其中一个端部压靠在轴套12上,另一端压靠在台肩13上。
图9至11示出脚轮的一实施例,其中,杆12不设置有一盲孔14,通过在杆12的外边缘装头,获得用来保持轴套16的唇形物15,这样,形成一从杆12向外突出的轴环,通过沿轴向作用在轴套16上,保持环18受压。
