    • A light reflector includes a plurality of opaque, generally triangular panels connected together to form a three dimensional geometric figure surrounding an inside space. Each panel has a reflective surface facing the inside space and each corner of each of the panels is adjacent a corner of an adjacent panel. The panels are spaced apart from each other by rectangular, open areas. An artifical light source is placed inside the inside space. The reflective surfaces relect light from the artificial light source and direct reflected light toward the rectangular open areas. Plants are situated adjacent the rectangular open areas and receive light emanating therefrom.
    • 光反射器包括连接在一起以形成围绕内部空间的三维几何图形的多个不透明的,大致三角形的面板。 每个面板具有面向内部空间的反射表面,并且每个面板的每个角部邻近相邻面板的拐角。 面板通过矩形开放区域彼此间隔开。 人造光源放置在内部空间内。 反射表面反射来自人造光源的光,并将反射光直接朝向矩形开放区域。 植物位于矩形开放区域附近并且接收从其发出的光。

    • A clamp 10 for holding two elongate members 23a, 23b so that they extend at a preset angle from each other, comprising: two clamp portions 12, 14 each having co-operating engaging surfaces 16a, 16b, each clamp portion having an axial bore 18a, 18b extending perpendicularly to the engaging surfaces and a receiving portion for holding one of the elongate members; a stem or rod 19, passing through the bore of the clamp portions and attached at one end to a lever or handle 20 for rotating the stem in the bore, and a cam acting between the stem and at least one of the clamp portions so that the clamp portions can be moved from a position in which the engaging surfaces are not engaged to a position in which the engaging surfaces co-operatively engage by rotating the lever by approximately 90°. An umbrella assembly 40 comprising an umbrella head and a pole 42 for supporting the umbrella head, the umbrella head having a runner slidably mounted on a shaft portion of the umbrella head and stretchers extending radially from the said runner to the ribs, and a clamp 10, 10′, 10″ for releasably attaching the umbrella head to the pole.
    • 用于保持两个细长构件23a,23b使得它们彼此以预设角度延伸的夹具10包括:两个夹持部分12,14,每个夹具部分12,14具有配合的接合表面16a,16b,每个夹持部分具有 垂直于接合表面延伸的轴向孔18a,18b和用于保持细长构件之一的容纳部分; 杆或杆19穿过夹具部分的孔并在一端附接到杠杆或手柄20上,用于将杆旋转到孔中,以及凸轮,其作用在杆与至少一个夹紧部之间,使得 夹紧部分可以从接合表面未接合的位置移动到接合表面通过使杠杆旋转大约90°来共同接合的位置。 伞组件40,其包括伞头和用于支撑伞头的杆42,伞头具有可滑动地安装在伞头部的轴部上的滑道和从所述跑步者径向延伸到肋的拉杆,以及夹具10 ,10',10“,用于将伞头可释放地连接到杆上。
