Abstract
Abstract A utility type cart designed for towing by hand or behind a bicycle which can be quickly converted without the use of tools from a wheeled vehicle into a sled-type unit for use on snow. A pair of wheels are mounted on a pivotably attached tow bar member joined to the tow bar handle, such that rotation of the handle about the top of the cart, from one end of the cart to the other end, acts to elevate or depress the wheels above or below the level of the cart bottom.

Claim 1
Independent Claim
353 words
A utility cart designed to be alternately towed either on wheels or on snow runners with the wheels raised above the bottom of the cart body, comprising a cart body formed with a bottom panel joined to two side panels and two end panels fitted with sled-like runners attached to the undersurface of the bottom panel of the cart body, with an assembly of two wheels each rotatably fitted to an end of a Ushape frame that is pivotably mounted to each of the two side panels of the cart body, said frame being of a size to extend about the side panels and alternately extend about either the first end panel or the second end panel of the cart body, depending upon the pivoted position of the frame, with the wheels that are attached to the frame ends oriented so that the bottom of the wheels lie below the plane of the undersurface of the sled-like runners when the frame is pivoted to extend about the said first end panel, and with said wheels oriented so that the bottom of the wheels lie above the plane of the bottom panel of the cart body when the frame is pivoted to extend about the said second end panel, said frame integrally fastened to a tow bar that extends from the general mid-section of the frame in a direction away from the cart body, together with a telescopic member fastened to one end to the assembly of the tow bar and frame, which telescopic member may be latched at its other end alternately to a bracket fastened to the first end panel or to a similar bracket fastened to the second end panel, for securing the two bar and frame assembly in either one or two positions for either towing the cart with the first end panel in the forward position with the wheels engaging the ground surface below the cart bottom or alternately towing the cart with the second end panel in the forward position and with the wheels upraised so that the sled-like runners contact the ground surface below the cart bottom.
