    • A molded frame backboard assembly for supporting a rebound member between separately formed front and rear frames such that the peripheral edge of the rebound member is encapsulated within the frame. The rear frame preferably is formed as one piece of plastic material having sufficient strength and rigidity to support the rebound member and may include an internal reinforcing structure integrally molded therewith. The front frame preferably is molded from plastic and has a large central opening providing substantially unobstructed access to the rebound surface of the rebound member. The rear frame includes a recess that locates the rebound member in a predetermined position within the rear frame. The front and rear frame members include cooperating alignment structures that enable the front frame to be easily located on and attached to the rear frame after the rebound member has been positioned within the rear frame.
    • 一种用于在单独形成的前框架和后框架之间支撑回弹构件的模制框架背板组件,使得回弹构件的外围边缘被封装在框架内。 后框架优选地形成为具有足够的强度和刚度的一片塑料材料,以支撑回弹构件,并且可以包括与其一体模制的内部加强结构。 前框架优选地由塑料模制而成,并且具有大的中心开口,基本上无阻碍地进入回弹构件的回弹表面。 后框架包括将回弹构件定位在后框架内的预定位置的凹部。 前框架构件和后框架构件包括协作对准结构,其使得在回弹构件已经定位在后框架内之后,前框架能够容易地定位在后框架上并附接到后框架。

    • 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.
    • 一种分离的网附件系统,用于将篮球网可拆卸地安装到具有弹性网夹的篮球场的边缘。 网夹包括可附接到轮辋的基部和用于可拆卸地保持与轮缘相关联的网的保持器部分。 边缘优选地包括沿着其下表面定位的多个螺柱或孔,用于接合设置在夹子上的孔或突起内,由此夹子保持与轮缘接合。 在一些实施例中,夹子设置有用于保持网的柔性指状物,其中手指将响应于施加到网的预定力而释放网。 在另外的实施例中,当预定的力施加到网上时,夹子适于被拉出边缘。

    • A basketball goal (14) and backboard (2) assembly are provided for shipment in a carton (120) having a girth plus longest dimension less than or equal to 108 inches, for shipment by common carrier. A backboard (2) is provided with reduced outside dimension for saving material cost, particularly fiberglass, yet still affording 92% of the playing surface area of a conventional board. Support bracket hardware (30) is provided with significantly reduced shipping height requirements, yet providing precise 90.degree. mounted orientation of the rim (20) relative to the backboard (2), by slight deformation of interlocking bosses (78, 80) in mating nested relation upon tightening of bolts (62 and 68) through mounting apertures (58, 60, 64, 66) subject to tolerance deviation which may otherwise deviate the position of the rim (20) from horizontal, particularly at the forward edge.
    • 提供篮球目标(14)和背板(2)组装,用于在具有小于或等于108英寸的围长加最长尺寸的纸箱(120)中装运,以由公共运输工具装运。 背板(2)具有减小的外部尺寸以节省材料成本,特别是玻璃纤维,仍然提供传统板的92%的游戏表面积。 支撑支架硬件(30)具有显着降低的运输高度要求,同时通过互锁嵌套(78,80)的轻微变形,提供边缘(20)相对于背板(2)的精确90°安装方向 通过安装孔(58,60,64,66)拧紧螺栓(62和68)而受到公差偏差的关系,否则可能会将轮辋(20)的位置从水平方向偏离,特别是在前缘。
