发明名称 Picket fence
摘要 A picket fence has a plurality of light weight plastic fence pickets that can be snapped together with other like fence pickets to form either a solid fence or a fence having a space between upright members. Each fence picket includes a rigid member and a plurality of substantially horizontal members fixedly attached to the upright member. The fence pickets are held together by a plurality of pegs located on the portion of the horizontal member adjacent to the upright member and a plurality of apertures through each of the horizontal members. The pegs have a stem and a button top of substantially the same size as the aperture. The peg of the fence picket passes through the aperture of another fence picket and the button top of the peg holds the pickets together. The button tops may be slightly larger than the apertures and the horizontal members may be mildly flexible to enable the button tops to be pushed through the aperture.
