    • A breakaway basketball goal assembly (20) includes a first mounting plate (30) for stationary mounting to the front of the backboard (22) and a second mounting plate (42) pivotally mounted to the first mounting plate and rigidly connected to the rim (24). The rim can pivot up or down in response to respective up and down forces, with the required downward force being greater, to provide differential breakaway. Left and right pivoting are also provided, to afford four way pivoting. Strength-increasing walls 102, 104, 106 are provided for the first mounting plate to prevent bowing away from the backboard and additionally serve the function of providing a protective finger pinch shroud. A universal structure selectively provides a choice between breakaway and non-breakaway applications without changing the manufacturing operation producing the goal assembly, to reduce cost.
    • 分离式篮球目标组件(20)包括用于固定地安装在背板(22)的前部的第一安装板(30)和枢转地安装到第一安装板并刚性地连接到轮辋的第二安装板(42) 24)。 轮辋可以响应于相应的上下力而向上或向下枢转,所需的向下的力更大,以提供差异的分离。 还提供左右旋转,以提供四路枢转。 为第一安装板提供强度增加壁102,104,106以防止从背板弯曲,另外还起到提供保护性手指夹紧罩的功能。 通用结构选择性地提供分离和非分离应用之间的选择,而不改变产生目标组件的制造操作,以降低成本。

    • A moisture activated wiper sensor has all necessary electronic and optical components for detecting moisture and performing signal processing in a single module which mounts to a vehicle windshield. The packaging of the optical components and associated electronic circuitry in an acceptably small housing is achieved by use of insert-molded lenses and infrared emitters and detectors mounted on separate printed circuit boards called wing boards. Wing board supports molded into the housing assure proper orientation of the wing boards relative to the lenses. Flexible cables connect the wing boards to a main circuit board.
    • 水分激活的刮水器传感器具有用于检测湿气并在安装到车辆挡风玻璃的单个模块中执行信号处理的所有必要的电子和光学部件。 光学部件和相关联的电子电路在可接受的小壳体中的封装通过使用嵌入式透镜和安装在称为翼板的分开的印刷电路板上的红外发射器和检测器来实现。 翼板支撑模制到壳体中,确保翼板相对于透镜的适当取向。 柔性电缆将翼板连接到主电路板。

    • An elevator system for a basketball backboard comprising, in combination, a parallelogram frame and a backboard connected to the frame. A ratchet and pawl arrangement is connected between one of the arms and one of the vertical surfaces of the parallelogram frame so that a first vertical surface is freely movable upward relative to a second vertical surface and is held in a selected vertical position when the vertical lifting force applied to the first vertical surface is removed. The ratchet includes a plurality of ratchet teeth connected to and movable with one arm relative to the first vertical surface. The pawl is pivotally connected to the first vertical surface and disposed for engagement with the ratchet teeth to hold the first vertical panel in a selected vertical position when the vertical lifting force is removed. Also provided is a structure for biasing the pawl toward selective engagement with the ratchet teeth, the engagement depending upon the vertical position of the first vertical surface relative to the second vertical surface. A bell crank lever is pivotally connected to the first vertical surface and operatively associated with the ratchet and pawl arrangement, with a structure for connecting the bell crank lever to the pawl that is responsive to pivotal movement of the bell crank to move the pawl out of engagement with the ratchet teeth.
    • 一种用于篮球背板的电梯系统,其组合包括连接到所述框架的平行四边形框架和背板。 棘轮和棘爪布置连接在一个臂和平行四边形框架的一个垂直表面之间,使得第一垂直表面相对于第二垂直表面可自由地向上移动,并且当垂直提升时保持在选定的垂直位置 施加到第一垂直表面的力被去除。 棘轮包括多个棘轮齿,其连接到一个臂并且可相对于第一垂直表面移动。 棘爪枢转地连接到第一垂直表面并且设置成与棘轮齿接合,以在垂直提升力被移除时将第一垂直面板保持在选定的垂直位置。 还提供了一种用于将棘爪偏压成与棘齿选择性接合的结构,该结合取决于第一垂直表面相对于第二垂直表面的垂直位置。 钟形曲柄杆枢转地连接到第一垂直表面并且可操作地与棘轮和棘爪装置相关联,具有用于将钟形曲柄杆连接到棘爪的结构,其响应于钟形曲柄的枢转运动以将棘爪移出 与棘轮啮合。
