    • An upright surface treating appliance includes a main body having a user operable handle, and a support assembly for allowing the appliance to be rolled along a surface using the handle. The support assembly includes a yoke and a pair of wheels rotatably connected to the yoke, the yoke being shaped so that a section of the yoke lies between the rims of the wheels. A surface treating head is connected to the yoke. The main body is pivotably connected to the yoke for movement about a pivot axis passing between the wheels, and so that a part of the main body is located between the rims of the wheels. As the main body is pivoted about said axis from an upright position to a reclined position, the spacing between said section of the yoke and said part of the main body increases, and so a shield is provided for covering the gap so formed between said section of the yoke and said part of the main body to prevent dirt and dust from passing into the support assembly through the gap.
    • 立式表面处理装置包括具有用户操作手柄的主体和用于使用手柄沿着表面滚动器具的支撑组件。 支撑组件包括轭和可转动地连接到轭的一对轮,轭被成形为使得轭的一部分位于轮的轮缘之间。 表面处理头连接到轭。 主体可枢转地连接到轭,用于围绕通过车轮的枢转轴线运动,并且使得主体的一部分位于车轮的轮缘之间。 当主体围绕所述轴线从直立位置枢转到倾斜位置时,轭的所述部分与主体部分之间的间隔增加,因此设置屏蔽件以覆盖形成在所述部分之间的间隙 的轭和所述主体的一部分,以防止灰尘和灰尘通过间隙进入支撑组件。

    • A support assembly for a surface treating appliance includes a roller having one or more tires, wherein the one or more tires are fused to the roller. The roller can include a polymer such as polypropylene and may also include a glass filled impact modified copolymer such as a 20% glass filed impact modified copolymer. The tires can include a thermoplastic elastomer such as a modified polymer including a mixture of polypropylene and an ethylene propylene diene monomer. The thermoplastic elastomer may have a hardness of from 55 to 95 Duro measured on the A scale, more specifically from 70 to 79 Duro on the A scale or from 80 to 95 Duro on the A scale.
    • 用于表面处理设备的支撑组件包括具有一个或多个轮胎的辊,其中所述一个或多个轮胎与辊熔合。 辊可以包括聚合物如聚丙烯,并且还可以包括玻璃填充的冲击改性共聚物,例如20%玻璃冲击改性共聚物。 轮胎可以包括热塑性弹性体,例如包括聚丙烯和乙烯丙烯二烯单体的混合物的改性聚合物。 所述热塑性弹性体可具有在A刻度上测得的55至95Duro的硬度,更具体地,在A刻度上为70至79Duro,或在A刻度上为80至95Duro。
