    • A step stool nestable for stacking is formed vertically tapered with the smaller end closed to form a horizontal stepping surface. The interior of the shell has attachment surfaces faces upon which the casters are attached for use.Initially the casters are mounted on the undersurface of the closed end to permit stacking of the stools for bulk transport or shipment in quantities. Upon separating the stools in the stack, the user removes the platform and casters from the undersurface of the closed end and attaches them to attachment surfaces in the shell. In the disclosed embodiment a platform member is attached to the shell and the casters mounted on the platform member. In the disclosed embodiment, the casters and platform member are enclosed in a container and releasably secured to the undersurface of the closed end of the shell for stacking.
    • 可堆叠堆叠的台凳形成为垂直渐缩,较小的一端封闭形成水平的踏面。 壳体的内部具有附接表面,脚轮连接在该表面上用于使用。 最初,脚轮安装在封闭端的下表面上,以便堆放大量的散装运输或大量运输。 在分离堆叠中的粪便时,使用者将平台和脚轮从封闭端的下表面移除并将其附接到壳体中的附接表面。 在所公开的实施例中,平台构件附接到壳体和安装在平台构件上的脚轮。 在所公开的实施例中,脚轮和平台构件被封装在容器中并且可释放地固定到壳的封闭端的下表面以进行堆叠。

    • A portable, collapsible radiant heater includes a base and a support mounted to the base. The support has a collapsed position wherein the base is configured to at least partially receive the support, and an extended position wherein the support extends upwardly from the base. A heater-head for generating radiant heat is connected to the support. A reflector is mounted to one of the heater-head and the support. The reflector at least partially surrounds the heater-head for downwardly reflecting radiant heat generated by the heater-head. The reflector and heater-head are reciprocally movable between the collapsed position wherein the reflector and heater-head are in close proximity to the base and the extended position wherein the reflector and heater-head are distant from the base.
    • 便携式,可折叠辐射加热器包括基座和安装到基座的支撑件。 支撑件具有折叠位置,其中基部构造成至少部分地容纳支撑件,以及延伸位置,其中支撑件从基部向上延伸。 用于产生辐射热的加热器头连接到支撑件。 反射器安装在加热器头和支架之一上。 反射器至少部分地围绕加热器头部,用于向下反射由加热器头产生的辐射热。 反射器和加热器头在折叠位置之间往复运动,其中反射器和加热器头靠近基座和延伸位置,其中反射器和加热器头远离基座。

    • The present invention relates to a portable sprayer for applying a diluted product to a surface to be treated. The sprayer includes a housing including an inlet for supplying pressurized water to the sprayer, a first water only outlet, and a second diluted product only outlet. A mixing chamber is located within the housing. The mixing chamber is dimensioned to securely hold the product and is in fluid communication with the second outlet. A first flow passage extends through the housing. The first flow passage is in selective fluid communication with the inlet and the first outlet. A second flow passage extends through the housing. The second flow passage is in selective fluid communication with the first flow passage and the mixing chamber. A wall of the second flow passage is configured to direct the pressurized water flowing through the second flow passage into the mixing chamber to evenly dissolve the product and provide a generally consistent product to water ratio.
    • 本发明涉及一种用于将稀释产物施加到待处理表面的便携式喷雾器。 喷雾器包括壳体,该壳体包括用于向喷雾器供应加压水的入口,仅第一水出口和仅第二稀释产物出口。 混合室位于壳体内。 混合室的尺寸设计成可靠地保持产品并与第二出口流体连通。 第一流动通道延伸穿过壳体。 第一流道与入口和第一出口选择性地流体连通。 第二流动通道延伸穿过壳体。 第二流动通道与第一流动通道和混合室选择性地流体连通。 第二流动通道的壁被构造成将流过第二流动通道的加压水引导到混合室中以均匀地溶解产品并提供大致一致的产品与水的比例。
