Abstract
A folding tent frame for collapsible tents includes upright pole sets, fixed couplers, stoppers, movable couplers and traverse frame members. Specifically, each stopper is provided on the uppermost pole of the upright pole set at a position lower than the fixed coupler so as to prevent the lower pole of the upright pole set from moving up beyond the stopper and so that the movable coupler is slidable over the stopper and the lowest pole of the upright pole set, and is kept from moving up beyond the stopper. The lower pole is larger than the upper pole in cross section. The structure of this folding tent frame provides improved strength and stability.
Claims18
A folding tent frame, comprising:
- a plurality of telescopically expandable sets of upright poles, each set of upright poles having at least two poles, a lower pole and an upper pole, each pole having a top and a bottom, the upper pole being smaller than the lower pole in cross section;
- a fixed coupler mounted to the top of each upper pole;
- a stopper mounted on each upper pole at a position lower than the fixed coupler, said stopper preventing the lower pole from moving up and being juxtaposed completely over the upper pole;
- a movable coupler slidable on the stopper and the lower pole and prevented by the stopper from moving up past the stopper;
- a plurality of traverse, foldable, scissoring frame members each joined to a fixed coupler and a movable coupler;
- and
- a wheel disposed on a pole directly above the lower pole so that the wheel is projectable from the lower pole and contactable with the ground when the poles are withdrawn.
