Abstract
A portable snow shovel that includes a unique collapsible mechanism. One embodiment of the shovel includes both an expanded and collapsed state. The shovel includes a blade member and an elongated shaft member. The elongated shaft member is slidably engaged to the blade member through a recess that extends through the blade member. The elongated shaft member is able to translate with respect to the blade member between the extended and collapsed states. The collapsed state relates to a configuration in which the elongated shaft member is extended through the recess and over the blade member a particular amount. The extended state relates to a configuration in which the elongated shaft member is extended through the recess and away from the blade member a particular amount.
