A vent of foldable tent frame

Abstract

The present invention provides a foldable tent frame with a double-roof vent typically comprised of poles, stay bars and roof cross braces hinged on a tip hub, all of them construct the main body of the tent, a small ventilation roof-boom frame connected on the top center of the main body of the tent; said ventilation roof-boom frame is consisted of a central stem, side struts, upper bracing ribs and central rib-hub; said central stem is fastened on the up side of the tip hub with the low end vertically, and fastened on the bottom side of the rib-hub with the top end; each side strut is hinged on one side of the corresponded roof brace with the low end, and hinged on the same side of the coordinated upper bracing rib with the top end; all the upper bracing ribs are hinged on the central rib-hub with the tip ends respectively. This structure can make the whole tent mount and disassemble conveniently and rapidly, and guarantee the tent use normally.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a tent, and more particularly to a double-roof vent of foldable tent frame. [0003] 2. Description of Prior Art [0004] In accordance with the conventional technology, the foldable tent frame with top vent is typically comprised of poles, stay bars and roof cross braces hinged on a tip hub, all of them construct the main body of the tent, a small ventilation roof boom frame plugged on the top center of the main body of the tent, coordinating to it the awning of the tent having a ventilation hole built upon the central portion, and a top shield built upon the ventilation hole for covering on the ventilation roof-boom frame by tying connection with ropes, so that said ventilation roof-boom frame can pass through the ventilation hole to be covered exactly by the top shield as putting on the awning over the tent frame to form a double-roof vent at the top center of the tent to get good ven...

AI Technical Summary

Benefits of technology

[0009] As utilizing above-mentioned project, due to the ventilation roof-boom frame is integrated into the main body of the tent frame as a whole one, the ventilation roof-boom frame is pitched up or folded up along with the main frame of the tent without individually mounting or disassembling it, hence the tent applying the present invention can be efficiently pitched up or folded to a compact configuration conveniently and rapidly; and avoids losing the separated part, and guaranteed to be used normally.

Problems solved by technology

But, said ventilation roof-boom frame is designed to in separated part from the main body of the tent, so in assembling, firstly need to pitch up the whole tent frame, then mount the roof-boom frame on the top center, so that the operations of pitching and collapsing the tent become more complicated, especially to the bigger size and higher tent, mounting and disassembling the roof-boom frame is more inconvenient.

And the individual roof-boom frame and the main body of the tent are easy to be lost as in disassembling and storing, so that it affects to the normal use.
