    • A basketball goal assembly (10) includes a base (11), a pole assembly (12) carried by the base (11), a rim assembly (14) pivotally carried by the pole assembly (12) and a backboard (13) carried by the pole assembly (12). The pole assembly (12) has a front face (21) having a recess (27) therein. A lug (36) on the rim assembly (14) is received in the recess (27) to hold the rim assembly (14) in a useable condition. Upon a downward force on the rim assembly (14), the rim assembly (14) breaks away from the pole assembly (12) as the lug (36) comes out of the recess (27). A yoke (59) extends between the base (11) and the pole assembly (12) to assist in supporting the pole assembly (12). However, the yoke (59) may be removed from the pole assembly (12) and the base (11) and positioned in a compartment (64) formed in the base (11). The pole assembly (12) may then be rotated to be generally flat with the base (11) and to be positioned over the yoke (59). A scoring system (44) may also be provided on the pole assembly (12).

    • An oscillating sprinkler comprises a fixed base assembly (12) and an upper housing (14) from which water distributing arms (16, 18, 20, 22) extend. A bearing member (66) depends from the upper housing (14) and is seated within the base assembly (12). An upper surface (26) of the base housing (12) comprises an undulating cam surface and bend portions (110) of the arm members act as cam followers. Bend portions (110) engage cam surface (26) and cause a reciprocal tilting of the upper housing (14) about the bearing member (66) as the upper housing (14) rotates about the base assembly (12). Water ejected from orifices (114) in the arm members (16, 18, 20, 22) act to propel the upper housing along its rotational path. A cap member (144) is rotationally mounted to the top of the upper housing (14) and pressurized water ejected through orifices (148) in the cap member (144) act to rotate the cap member in a direction opposite to the direction in which the upper housing rotates.
    • 摆动喷洒器包括固定基座组件(12)和上部壳体(14),水分配臂(16,18,20,22)从该上部壳体延伸。 轴承构件(66)从上壳体(14)延伸并且位于基座组件(12)内。 基座壳体(12)的上表面(26)包括起伏凸轮表面,并且臂构件的弯曲部分(110)用作凸轮从动件。 随着上壳体(14)围绕基座组件(12)旋转,弯曲部分(110)接合凸轮表面(26)并且使得上壳体(14)围绕轴承构件(66)相互倾斜。 从臂构件(16,18,20,22)中的孔(114)排出的水用于沿其旋转路径推动上壳体。 帽构件(144)旋转地安装到上壳体(14)的顶部,并且通过帽构件(144)中的孔(148)喷射的加压水用于使盖构件沿与其中的方向相反的方向旋转, 上壳体旋转。
