    • A finial support arrangement is provided for window coverings and the like, including a hollow ended support rod or tube, a support sleeve lodged within the rod, and a decorative finial supported in and by the sleeve. The finial includes a support post that is force or interference fitted into the sleeve. The sleeve, in turn, is force or interference fitted into the tube. The sleeve is made of a material that is softer than the support post and may be deformed during insertion of the post. The arrangement is particularly useful for supporting cast or wrought metal finials in rigid support tubes or rods, and alleviates the need for close tolerances on either the tube interior diameter or the support post outer diameter that would otherwise be needed to provide the desired interference fit.
    • 为窗帘等提供了一种完整的支撑装置,包括一个中空的末端支撑杆或管子,一个支撑套筒,该支撑套筒装在杆内,以及一个由套筒支承的装饰性的金属件。 最终包括一个支撑柱,其是装配到套筒中的力或干涉物。 套筒又是力或干涉装配在管中。 套筒由比支撑柱更软的材料制成,并且在插入柱时可能会变形。 该布置对于在刚性支撑管或杆中支撑铸造或锻造金属部件是特别有用的,并且减轻了在管内径或支撑柱外径处的紧公差的需要,否则将需要其提供所需的过盈配合。
