Abstract: The present invention relates to a portable bag distending and supporting apparatus for holding a bag, such as a plastic leaf collector or trash collector, with the receiving end thereof in open position essentially perpendicular to a horizontal surface, thus to permit leaves and trash to be raked or swept into the interior of the bag. The device is characterized by a support mechanism which holds the receiving end of the bag against tilting without requiring the use of stakes or spikes embedded in the ground, the support apparatus in addition functioning at least partially to extend the bag in a lengthwise direction to facilitate filling. The device is further characterized by being constructed of inexpensive components which may be readily assembled by the user, thus reducing the bulk of the apparatus in shipping.
