Abstract

A lightweight portable article carrying cart. The cart comprises a main frame made up of two upright tubular members and rod-like braces to maintain them in parallel space relationship. The main frame is provided with a pair of wheels and a lower load carrying platform shiftable between a load carrying position and a stowed position. The main frame is provided with a telescoping handle assembly comprising a telescoping three piece tubular assembly supported by each of the main frame tubular members. The upper ends of the three piece tubular assemblies are joined by a grip. The tubular members of the three piece tubular assemblies are provided with locking detents which lock the handle assembly in its extended position. The handle assembly carries a single release bar shiftable between a normal position and a depressed, unlatching position. When the bar is shifted from its normal position to its unlatching position by the cart operator's hand or foot, the telescoping handle assembly can be shifted from its extended to its retracted position. The release bar is biased to its normal position and returns thereto automatically. The cart can be provided with an auxiliary rear wheel assembly so that the cart is supported by four wheels when carrying a load having a high center of gravity. The cart may also be provided with an upper article carrying tray, an upper undercarriage which can be rolled beneath a preloaded tray which can thereafter be secured to the cart, and a lower auxiliary wheeled platform for heavy, low center of gravity loads. All attachments can be affixed to and removed from the cart with a minimum of manpulative steps and without the use of tools.
