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. |
