摘要：A pivotable cart is disclosed which has a first and second support members forsupporting a rolled material. The first and second support members are pivotablerelative to each other to a storage position. In the pivoted storage position, the cartrequires a minimum amount of space. The cart may be easily pivotable outwardly to a useposition where it will adequately support an elongate rolled material. The supportmembers are preferably identical, and connected to a pair of spaced wheels such that thesupport members pivot about the wheel axis relative to each other. A chain prevents thetwo support members from pivoting relative to each other beyond a predeterminedamount. Further, the support members each include a support surface having a generallyV- shape with an apex aligned with an apex of the other support member to provide aditch for support of the coiled material. The apex on each of the support members arespaced laterally inwardly from a cross member connecting the support structure to awheel bushing. In this way the weight of the carpet is borne laterally between the crossmembers such that the cart adequately supports the weight.
