    • The invention relates to lifting devices for raising and lowering audio equipment. Technical result consists in providing a simple and reliable winch structure, increased service life of the winch and enhanced accuracy of audio equipment positioning. The technical result is achieved by a winch for audio equipment, comprising a cable and a housing that contains a drive and a drum, wherein a first part of the drum is designed for spooling a first portion of the cable, a second part of the drum is designed for spooling a second portion of the cable and presents a reel that has, disposed on the central bushing, a barrel for spooling the second cable portion, and two side plates, and an external annular wall is provided between the side plates of the reel, the diameter of the external annular wall being greater than that of the barrel of the reel; wherein one end of the first cable portion is designed to be connected to the audio equipment being suspended, and the second end of the first cable portion is fastened to the first part of the drum and connected to the second cable portion; one end of the second cable portion is connected to the first cable portion and is inserted into the reel, being fastened in the region of its annular wall, and the second end of the second cable portion is led out of the reel, being fastened in the region of the barrel of the reel, and is designed to be connected to an external signal path; wherein inner surface of the reel side plates is coated with a sliding material; the cable inside the reel has a coating that provides sliding of the cable relative to adjacent coils and relative to the sliding material covering the reel side plates.

    • In accordance with the present invention, a portable riser unit (30) for supporting persons or objects above the ground, a floor, a stage or the like is provided. The riser (30) broadly comprises a base (32), generally rectangular step members (80, 82), and hinge joints (36) for pivotally, hingedly connecting the step members (80, 82) to the base. The base (32) has an integrally formed, convoluted internal or interior support and baffle wall structure and may be filled with an appropriate low density, high volume material. Each step member (80, 82) also may be of this construction; however, the step members (80, 82) may or may not have an internal support wall. The step members (80, 82) are operably coupled to the base (32) by double axis hinges including hinge blocks received in complementary hinge wells in the base (32) and step members (80, 82). The hinges are self-leveling to present a substantially smooth, level riser support surface in every possible configuration. The riser may be molded of a plastic material and includes integral hand grips (98) to facilitate moving step members (80, 82) or the entire riser (30). By manipulating the step members (80, 82), the riser (30) may be re-shaped into a variety of operable configurations. The invention also encompasses connector keys for connecting two or more risers (30) into a riser assembly.
    • 根据本发明,提供了一种用于支撑地面上的人或物体的便携式立管单元(30),地板,台架等。 提升器(30)广泛地包括基部(32),大体上矩形的台阶构件(80,82)和用于将台阶构件(80,82)铰接地连接到基座的铰链接头(36)。 基座(32)具有整体形成的,卷曲的内部或内部支撑和挡板结构,并且可以填充适当的低密度大体积材料。 每个步骤构件(80,82)也可以是这种结构; 然而,台阶构件(80,82)可以具有或不具有内部支撑壁。 台阶构件(80,82)通过双轴铰链可操作地联接到基座(32),双轴铰链包括接收在基座(32)和台阶构件(80,82)中的互补铰链井中的铰链块。 铰链是自流平的,以在每种可能的构造中呈现基本平滑的液位立管支撑表面。 提升器可以由塑料材料模制,并且包括一体的手柄(98),以便于移动步骤构件(80,82)或整个提升管(30)。 通过操纵台阶部件(80,82),提升管(30)可以重新形成各种可操作的构型。 本发明还包括用于将两个或多个立管(30)连接到提升管组件中的连接器键。
