Like reference numerals indicate like parts in both views. I

As usual in the present type of playground sand boxes, the box or containerl is of an open top, shallow, and rectangular shape, preferab formed of plate metal and supported a short distance above the ground by The material part of this invention, in connection with the above described sand box structure, com rises a plurality of vertical guide posts 3, xedl attached at their lower ends to the sides 0 the sand box 1, to provide a supporting means for a roofing or shade member now to e described.

In the preferred construction shown in the drawing the roofimgmember, above referred to, comprises a plurality of transverse rafter tuting a ske eton support-for -a roofing or covering 7, preferably formed of weather proof fabric.

In the present construction the roof structure above described, is vertically adjustable on the posts 3 by means of guide sleeves 8, secured to the sides of the rafter bars 4 aforesaid. Such guide sleeves 8 are of an angle formation, the horizontal webs of which are arranged at the bottom of the sleeves and formed with guide orifices which in connection with guide orifices formed in the ridge pole 5, provide effective guiding means for the roof structure in the vertical movement of the same upon the guide posts 3, and with the roof structure in its elevated condition shown in Fig. 1, it is maintained in such position by holding pins 9 passing transversely through the posts 3, immediately beneath the aforesaid horizontal webs of the guide sleeves 3, as shown.

With the roof structure in its lowered position, it rests on the top of the sand box 1, with its pliable roof covering 7 overlapping the margins of the box to protect the contents of the same from the weather, but more especiallyto prevent ingress of cats or other animals to the contents of the box and prevent the defilement of such contents with ex- .crements from said animals.
