    • Apparatus for aiding removal and replacement of a spa cover. The apparatus includes at least one lifting assembly secured relative to the spa tub, each having a lifting arm mounted for rotation relative to the spa tub and including a cover-engaging end coupled to the spa cover and a pivot end mounted for pivotal movement about a pivot axis. The lifting arm is rotatable through a range of motion about the pivot axis between a covering position and an uncovering position. A lifting system is provided for exerting a lifting force on the arm tending to lift the arm as the arm moves from the covering position toward the uncovering position, and for exerting a resistance force on the arm tending to resist movement of the arm from the uncovering position toward the covering position. The lifting system includes a link lever having a pivot end pivotally mounted to the lift arm at a link pivot location disposed between the arm pivot end and the cover-engaging end. A slider end of the link lever is constrained for sliding movement along a slider path of travel. A spring structure is connected to the link lever at a spring pivot location between the link lever pivot end and the slider end. The spring structure is also connected to the lift arm at a spring connection point, and is under compression when the lift arm is at the covering location.
    • 帮助移除和更换水疗护理的设备。 该装置包括至少一个相对于SPA浴盆固定的提升组件,每个升降组件具有安装成相对于SPA浴盆旋转的提升臂,并且包括联接到温泉护罩的盖接合端和安装成围绕 枢轴。 提升臂可以在覆盖位置和露出位置之间绕关于枢转轴线的运动范围旋转。 提供一种提升系统,用于当臂从覆盖位置朝向露出位置移动时,在臂上施加提升力,以便在臂上移动时提升臂,并且在臂上施加阻力以防止臂从露出部移动 朝向覆盖位置的位置。 提升系统包括连杆,该连杆具有枢转端,该枢转端枢转地安装在提升臂处,该连杆枢转位置设置在臂枢转端和盖接合端之间。 连杆的滑块端被限制用于沿滑动滑动路径移动。 弹簧结构在链节杆枢转端和滑块端之间的弹簧枢转位置处连接到连杆。 弹簧结构还在弹簧连接点处连接到提升臂,当提升臂处于覆盖位置时,弹簧结构被压缩。
