    • A method and apparatus for concealing a lift mechanism associated with a lift chair is provided. The lift chair includes a seating unit and a support frame. The apparatus is a piece of elastic material that includes a front panel, rear panel and a pair of side panels that are shaped to extend between the support frame and the seating unit. In particular, the side panels are tapered as they extend from the rear panel to the front panel. In concealing the lift mechanism, the front and rear panels extend around a front and rear bar respectively to conceal a top portion of the lift mechanism. In addition, front and rear panels may be coupled to one another by a coupling mechanism, such as a zipper. Further, a pull cord selectively secures the skirt to the bottom portion of the support frame.
    • 提供一种用于隐藏与升降椅相关联的升降机构的方法和装置。 升降椅包括座位单元和支撑架。 该装置是一块弹性材料,其包括前面板,后面板和成形为在支撑框架和座椅单元之间延伸的一对侧板。 特别地,当它们从后面板延伸到前面板时,侧板是渐缩的。 在隐藏提升机构时,前面板和后面板分别围绕前后杆延伸以隐藏升降机构的顶部。 此外,前面板和后面板可以通过诸如拉链的联接机构彼此联​​接。 此外,拉绳选择性地将裙部固定到支撑框架的底部。

    • A drop-in spring unit seat assembly includes a top grid spaced from a bottom grid having conical springs positioned therebetween. The conical springs are snap-fit for attachment to the top grid and/or bottom grid and require no mechanical fasteners nor complicated tools for such attachment. A pair of opposed detents are formed in the top and/or bottom turns of the spring and/or the detents formed in grid wires extending on the top and/or bottom grid. The opposed detent in the springs snap-fit engage with the depressions in the grid wires and a plurality of springs are interposed between the top grid and bottom grid to form the spring unit assembly. In selected embodiments, the spring unit includes multiple bottom grids attached via springs to a single top grid. The assembled spring unit can be dropped into a chair, seat or other article of furniture for attachment to and support by a pair of spaced frame members of the chair or other article of furniture.
    • 落入弹簧单元座椅组件包括从底部格栅间隔开的顶部格栅,其中具有定位在其间的锥形弹簧。 锥形弹簧卡扣配合以附接到顶部格栅和/或底部格栅,并且不需要机械紧固件或用于这种附接的复杂工具。 在弹簧的顶部和/或底部转弯处形成一对相对的棘爪,和/或在顶部和/或底部网格上延伸的栅格线形成的棘爪。 弹簧中的相对的卡定配合与栅格线中的凹陷接合,并且在顶格栅和底格之间插入多个弹簧以形成弹簧单元组件。 在选择的实施例中,弹簧单元包括通过弹簧连接到单个顶部格栅的多个底部网格。 组装的弹簧单元可以落入椅子,座椅或其他家具用品中,以附接到椅子或其他家具制品的一对隔开的框架构件并由其支撑。

    • A bedding or furniture spring product comprising a plurality of coil springs arranged in linear rows and columns. Each of the coil springs is preloaded by an endless strip of fabric, the strip of fabric encircling the exterior of one of the coil springs. The interior surface of the strip of fabric may be coated with a non-slip material so as to prevent the strip from falling or moving off the coil spring. Alternatively, the coil spring itself may be coated with a non-slip material. The strip of fabric leaves a portion of the end turns of the coil springs uncovered enabling the coil springs to be secured to a wire grid as for example by being wrapped around or clipped or laced to wires of the grid assembly. Alternatively, traditional hand 8-way tie may be used to connect the precompressed coil springs together and to a frame.
    • 一种床上用品或家具弹簧产品,包括以线性行和列排列的多个螺旋弹簧。 每个螺旋弹簧由织物的环形带预加载,织物条环绕着一个螺旋弹簧的外部。 织物条的内表面可以用防滑材料涂覆,以防止条带掉落或从螺旋弹簧移开。 或者,螺旋弹簧本身可以涂覆有防滑材料。 织物条带留下螺旋弹簧的端部匝部的一部分,使得螺旋弹簧能够固定到线栅上,例如通过缠绕或夹紧或缝合在电网组件的导线上。 或者,可以使用传统的手动8针系带将预压缩螺旋弹簧连接到框架。
