Abstract: A machine for exercising and rehabilitating the rotator cuff muscles that allows the user to easily isolate and manipulate, from a standing position, the internal and external rotation of the Rotator cuff with an outstretched arm, at any angle, to strengthen the Rotator Cuff muscles. Additionally it allows the user to strengthen the Pronation, Supination, Radial Deviation and Ulnar Deviation of the wrist.The aforementioned machine is comprised of a main rotating handle apparatus that consists of a gear joint, a ratchet mechanism and an angle adjustment pin. The handle is secured to linear rails that allow for height adjustment. The main rotating handle apparatus is connected to a stack of weights for resistance via a rubber coated steel cable and pulleys as well as connected to two counter weights via rubber coated steel cables and pulleys that relieve the weight of the handle for ease of adjustment.

Abstract: A conventional extension ladder modified to incorporate a foldable-platform-equipped trolley that can be raised and lowered with an electrically-powered winch. An open-channel guide rail is secured to each side of each section of the extension ladder, the guide rails extending the entire length of each section. Each side of the trolley is equipped with upper and lower sets of rotatable guide wheels. Each set comprises three guide wheels in stacked alignment. The trolley always runs on at least one pair of guide rails on opposite sides of the ladder, and may be running on both pairs of guide rails when it is positioned in the region of ladder section overlap. The trolley is equipped with upright posts to which a hand rail is secured. Extendable standards on the ladder base provide additional stability, and a pair of large wheels enhance ladder mobility.

Abstract translation: 一个常规的延伸梯被修改为结合了可以用电动绞盘升高和降低的可折叠平台的手推车。 开放通道导轨固定在延伸梯的每个部分的每一侧，导轨延伸每个部分的整个长度。 手推车的每一侧都装有上下两组可转动的导轮。 每组包括三个导向轮堆叠对齐。 手推车总是在梯子的相对侧上至少一对导轨上运行，并且当它们位于梯子部分重叠的区域时，它们可以在两对导轨上运行。 手推车装有立柱，扶手固定在该立柱上。 梯形底座上的可扩展标准提供了额外的稳定性，一对大的车轮增强了梯子的移动性。
