Patent attributes
A frame for automatic umbrella style canopy tents and a tent including the frame are disclosed. In the tent frame, the spreaders, which expand or collapse the upper ribs in radial directions, are configured as extendible members, thus reliably locking the tent frame in an expanded state and securely maintaining a pitched state of the tent. In the tent frame of the present invention, each of the spreaders includes a first spreader part coupled to the upper rib and a second spreader part which is coupled to a spreader holder and into which the first spreader part is inserted such that the first spreader part is extendible, with a spring installed in the second spreader part and causing the first spreader part to be extended. A repulsive force, which acts both on the first and on the second spreader parts due to the restoring force of the spring when the tent is pitched, restricts the movement of the spreader holder, thus securely maintaining a locked state of the tent frame, so that the pitched tent can be prevented from being undesirably closed.
