    • A connector assembly for resiliently actuated coupling of a first component of cylindrical configuration to a second component with a cylindrical recess utilizes a pair of interfitting inner and outer annular ring elements having first and second axial ends and axially extending overlying body portions. The first ends extend inwardly of the recess and the second ends are in surface contact with the circumferential surface of the cylindrical component. Each ring elements has a radially extending flange on one of its ends which extends along the ends of the other ring element into close surface relationship with one of the components. Resiliently deformable annular elements are disposed between the radial flange of each of the ring elements and the body portion of the other ring element, and adjustable elements on the two ring elements effect axial movement of the ring elements relative to each other to effect deformation of the resiliently deformable elements, thereby producing tensioning forces between the deforming elements and the component in surface contact therewith to secure the components in assembly.
    • 用于弹性致动的圆柱形构造的第一部件与具有圆柱形凹槽的第二部件的连接器组件利用一对相互配合的内外环形元件,其具有第一和第二轴向端部以及轴向延伸的上部主体部分。 第一端部延伸到凹部的内部,第二端部与圆柱形部件的圆周表面面接触。 每个环形元件在其一个端部上具有径向延伸的凸缘,其沿着另一个环形元件的端部延伸成与其中一个部件紧密的表面关系。 弹性变形的环形元件设置在每个环形元件的径向凸缘和另一个环形元件的主体部分之间,并且两个环形元件上的可调节元件实现环形元件相对于彼此的轴向运动,以实现 弹性变形元件,从而在变形元件与表面接触的部件之间产生张紧力,以将部件固定在组装中。

    • A boat trailer step assist includes a first and second support arm in pivotal relation to one another which provide steps that assist a user in entering or exiting a boat when trailered or in the process of being trailered. The support arms are arranged at an angle relative to the trailer tongue, with the first step at the level of the trailer tongue. When not in use, the second support arm pivots downward for compact stowage. When deployed, the support arms are in alignment with one another. A grab handle may be provided to assist the user in climbing or descending the steps.
    • 船拖车踏板辅助包括彼此枢转关系的第一和第二支撑臂,其提供当被执行或在被执行过程中帮助用户进入或离开船的步骤。 支撑臂相对于拖车舌片以一定角度布置,第一步骤处于拖车舌头的高度。 当不使用时,第二支撑臂向下枢转以进行紧凑的堆放。 当展开时,支撑臂彼此对齐。 可以提供抓握手柄来帮助使用者攀爬或降下台阶。
