摘要： A breakaway net attachment system for detachably mounting a basketball net to the rim of a basketball goal with resilient net clips. The net clips include a base portion attachable to the rim and a retainer portion for detachably retaining the net in association with the rim. The rim preferably includes a plurality of studs or apertures located along an undersurface thereof for engaging within apertures or projections provided on the clips, whereby the clips are retained in engagement with the rim. In some embodiments, the clips are provided with flexible fingers for retaining the net wherein the fingers will release the net in response to a predetermined force being applied to the net. In further embodiments, the clips are adapted to be pulled off of the rim when a predetermined force is applied to the net.

摘要： A basketball net clip for a breakaway net attachment system that detachably mounts a basketball net to the rim of a basketball goal at predetermined locations along the rim. The net clips are resilient and include a base portion attachable to the rim and a retainer portion for detachably retaining the net in association with the rim. The rim preferably includes a plurality of studs located along an undersurface thereof for engaging within apertures formed in the clips whereby the clips are retained in engagement with the rim. In one embodiment, the clips are provided with fingers for retaining the net wherein the fingers will release the net in response to a predetermined force being applied to the net. In a further embodiment, the clip is adapted to be pulled off of the rim when a predetermined force is applied to the net.

摘要： 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.
摘要翻译： 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。
