ABSTRACT:
The supports of the present invention further comprise a frame strut extending across a lower portion of the support frame. Two openings are defined in the frame strut which are adapted to receive ends of an expansion limiter piece. This limiter piece is generally V-shaped and has connection means at the end of each of the V legs for connection to frame struts of adjacent hose supports. The vertex of the limiter piece is located proximal to a vertex formed by the hinge of adjacent hose supports. At the vertex of the limiter piece and at locations near the connection means, living hinges are formed so that a user will experience relatively little resistance to opening, accordion-style, the invention hose supports.
