Wheels, or castors, are attached to the legs of what are commonly called collapsible shelters. The wheels, or castors, can be added to some or all of the legs, of which there are normally four. The wheels, or castors, can be of any type and attached in any fashion, i.e., bolted, clamped, welded, screwed, snapped in, grooved, pressed, glued, spring activated, telescopic, drop-down, rotational, slide, etc. 1. A faster method that allows one person , by them self , to easily set up , teardown , or move a collapsible shelter where:a. wheels are attached (in any manner) to the feet, or bottom portion of the legs of a new or existing collapsible shelter that allows those legs to slide freely and without the friction and the torque that is normally associated with the current design found in collapsible structures as they are set up, tore down, or moved.2. By adding wheels as in claim 1 , a safer method of setting up claim 1 , tearing down claim 1 , or moving a collapsible shelter that greatly reduces the propensity of the scissor mechanism portion of the structure to pinch the person performing the above action/s by reducing friction and stress on the structure.3. By adding wheels as in claim 1 , a method of adding useful life to a collapsible shelter by reducing undo tension and torque that tends to bend or damage the fragile scissors mechanisms and thus compromising or eliminating the structures ability to open and close properly. 1.

No. 7,604,212) and elevated canopies have been in use since at least 1986 (see U.S. Pat. No. 4,607,656). These units almost always have four legs. Usually a metal foot can be spiked to the ground in order to stop the unit from blowing away in gusty ...
