Abstract: Disclosed herein is a playpen sun cover designed to fit over an existing playpen and have adjustability both to accommodate to different sized playpens and also to enable the adjustment of the angle of pitch of the sides of the roof thereof. The device includes coupling devices which enable it to be rigidly affixed to the playpen and includes two roof halves pivotally connected together at a pivot. In order to enable the pitch of the cover to be adjusted while the cover is installed on a particular playpen, each of the elongated legs thereof includes a telescoping feature enabling each leg to be extended in length so as to facilitate changes in the pitch thereof. The roof material is elongated lengthwise sufficiently to enable the pitch of the cover to be adjusted through a wide range of variations while maintaining the entirety of the playpen suitably covered thereby.
