摘要： The convertible child high-chair and step stool can include a frame having a front leg stand and a rear leg stand. A height adjustment mechanism can be coupled to the front leg stand or the rear leg stand and can be adjustable along the vertical axis of the front leg stand or the rear leg stand from a raised position to a lowered position. The apparatus can also include a booster seat and removable platform step. In the raised position, the booster seat can be coupled to the height adjustment mechanism to provide a high chair. In the lowered position, the booster seat can be removed and the removable platform step can be coupled to the height adjustment mechanism and the frame to provide a step stool. The apparatus can also include wheel assemblies coupled to the frame that limit the potential for tip hazards in the step stool configuration.

摘要： A slip resistant step stool includes a step surface with four legs extending downward. A slip resistant surface is bonded to the step surface. The slip resistant surface may be disposed in a pocket and have a ridge surrounding it. The slip resistant surface can be a thermoplastic elastomer. The stool can be manufactured by inserting the slip resistant surface in a mold adapted to form a step stool, then injecting molten resin into the mold, thereby bonding the resin to the slip resistant step stool.

摘要： In accordance with the present disclosure, a portable riser unit for supporting persons or objects above the ground, a floor, a stage or the like is provided. The riser broadly comprises a base, generally rectangular step members, and hinge joints for pivotally, hingedly connecting the step members to the base. The base 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 also may be of this construction; however, the step members may or may not have an internal support wall. The step members are operably coupled to the base by double axis hinges including hinge blocks received in complementary hinge wells in the base and step members. 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 to facilitate moving step members or the entire riser. By manipulating the step members, the riser may be re-shaped into a variety of operable configurations. The invention also encompasses connector keys for connecting two or more risers into a riser assembly.
摘要翻译： 根据本公开，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，地板，台架等。 提升器广泛地包括基部，大体上矩形的台阶部件和用于将台阶部件枢转地铰接地连接到基部的铰链接头。 基座具有整体形成的，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。 每一步成员也可以是这样的结构; 然而，台阶构件可以具有或不具有内部支撑壁。 台阶构件通过双轴铰链可操作地联接到基座，包括接收在底座和台阶构件中的互补铰链井中的铰链块。 铰链是自流平的，以在每个可能的构造中呈现基本平滑的液位立管支撑表面。 提升管可以由塑料材料模制，并且包括一体的手柄，以便于移动步骤构件或整个提升管。 通过操纵台阶构件，提升管可以被重新形成各种可操作的构造。 本发明还包括用于将两个或多个立管连接到立管组件中的连接器键。

摘要： An aerobic step/bench exercise device includes a base having a horizontal platform with downwardly extending sides. The lower surface of the base includes a plurality of spaced leg receiving openings. Each of the openings has at least one notch extending upwardly from the lower surface into which a lateral projection from a respective leg would be inserted to control the extent to which a leg may be inserted into its respective opening.

摘要： An adjustable utility bench includes an elongated planar support platform. A mounting unit is secured to each end of the platform and includes a pair of legs hingedly mounted to the platform. The legs are interconnected by a brace so as to be jointly movable from its perpendicular position during use to its folded parallel position during storage. An extension is adjustably secured to each leg to vary the height of the platform.
