Abstract

Abstract A collapsible tow cart for transporting a load of beach items over sandy terrain to a beach site. The cart whose structure, save for the wheels, is fabricated of light weight metal tubing, has three basic components: the first of which is a rectangular main frame having parallel sides and upturned ends to define a carrying bed for the beach items. Perpendicular to the main frame and attached to the front thereof in a T-formation are the parallel sides of a rectangular cross frame whose down-turned ends are V-shaped. The apexes of these ends lie below the main frame and are joined by a transverse axle. Mounted on this axle in the open region between the ends of the cross frame and the sides of the main frame are two identical balls which function as cart wheels. The third component is a rectangular loop whose parallel sides are pivotally connected at a point adjacent the lower end thereof to the corresponding sides of the main frame at the rear thereof, whereby in the erect state of the loop, the lower end functions as a ground rest and the upper end as a handle to pull the cart, the loop being foldable over the main frame to collapse the cart.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 288 words
A collapsible tow cart for beach use and similar applications comprising: A a generally rectangular main frame having parallel beams and upturned front and rear ends to provide a loading bed; B a generally rectangular cross frame attached across the front of the main frame in a T-formation, said cross frame having parallel beams which are connected to the beams of the main frame at their points of intersection and having down-turned V-shaped ends whose apexes lie below the main frame and are joined by a transverse axle, the rear beam of the cross frame being attached to the upper face of the main frame beams to form a ledge, the front beam being attached to the under face of the main frame beams, the space between the ledge and the upturned front end of the main frame being sufficient to accommodate a cold chest; C two identical wheels mounted on said axle in the open region between the ends of the cross frame and the beams of the main frame; and D a rectangular loop having parallel beams pivotally connected to the beams of the main frame within the rear thereof at a position spaced from the upturned rear end at a point adjacent the lower end of the loop whereby when the loop is erected, the lower end functions as a ground rest and the upper end as a cart handle, such that when the cart is drawn, the loop abuts the upturned rear end of the main frame and is at an angle to the main frame, the loop being foldable over the main frame to collapse the cart, the space between the ledge and the erected loop being sufficient to accommodate folded beach chairs.
Claim 2
Dependent Claim 288 words
A collapsible tow cart for beach use and similar applications comprising: A a generally rectangular main frame having parallel beams and upturned front and rear ends to provide a loading bed; B a generally rectangular cross frame attached across the front of the main frame in a T-formation, said cross frame having parallel beams which are connected to the beams of the main frame at their points of intersection and having down-turned V-shaped ends whose apexes lie below the main frame and are joined by a transverse axle, the rear beam of the cross frame being attached to the upper face of the main frame beams to form a ledge, the front beam being attached to the under face of the main frame beams, the space between the ledge and the upturned front end of the main frame being sufficient to accommodate a cold chest; C two identical wheels mounted on said axle in the open region between the ends of the cross frame and the beams of the main frame; and D a rectangular loop having parallel beams pivotally connected to the beams of the main frame within the rear thereof at a position spaced from the upturned rear end at a point adjacent the lower end of the loop whereby when the loop is erected, the lower end functions as a ground rest and the upper end as a cart handle, such that when the cart is drawn, the loop abuts the upturned rear end of the main frame and is at an angle to the main frame, the loop being foldable over the main frame to collapse the cart, the space between the ledge and the erected loop being sufficient to accommodate folded beach chairs.
