Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a tent, and more particularly to a double-roof vent of foldable tent frame.

2. Description of Prior Art

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 ventilation effect, therefore the tent with the double-roof vent is welcome by the customers.

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.

OBJECTS AND SUMMARY OF THE INVENTION

It is therefore a main object of the present invention to provide a foldable tent frame with a double-roof vent that can be efficiently pitched up or folded to a compact configuration conveniently and rapidly, and guaranteed to be used normally.

For achieving the above-mentioned object, the present invention provides a foldable tent frame with a double-roof vent, which 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 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.

The foldable tent frame with a double-roof 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 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 via a pivot bearing, 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 top ends eccentrically and respectively so that the upper bracing ribs are closed between the roof cross braces and the side struts in folded state for folding to a minimalist volume.

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.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 1 to FIG. 3, a foldable tent frame with a double-roof vent provided by the present invention is typically comprised of poles 1, stay bars 2 and roof cross braces 3 hinged on a tip hub 4, 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 5, side struts 6, upper bracing ribs 7 and central rib-hub 8, wherein said central stem 5 is fastened on the up side of the tip hub 4 with the low end vertically, and fastened on the bottom side of the rib-hub 8 with the top end; each side strut 6 is hinged on one side of the corresponded roof brace 3 with the low end, and hinged on the same side of the coordinated upper bracing rib 7 with the top end; all the upper bracing ribs 7 are hinged on the central rib-hub 8 with the top ends respectively. Therein, for avoiding each member bar interferes in folded state and folding to as smallest as possible in volume, said each side strut 6 is hinged on one side of the corresponded roof brace 3 with the low end via a pivot bearing 9, and hinged on the same side of the coordinated upper bracing rib 7 with the top end; all the upper bracing ribs 7 are hinged on the central rib-hub 8 with the top ends eccentrically and respectively so that the upper bracing ribs 7 are closed between the roof cross braces 3 and the side struts 6 in folded state for folding to a minimalist volume.

As tending to fold the tent frame, just need to follow the way of folding the conventional tent frame to fold the present invention, such like in the state shown in FIG. 1, close the poles 1 of the main body to bring the stay bars 2 and the roof cross braces 3 to close, cooperating to FIG. 4 and FIG. 5, meanwhile the side struts 6 will draw the upper bracing ribs 7 under the driving coming from the roof cross braces 3 to close together until the ventilation roof-boom frame is completely folded along with the main body folding to finish folding the whole tent, as shown in FIG. 6.

As tending to pitch up the tent frame, also need to follow the way of pitching the conventional tent frame to pitch the present invention, such like in the state shown in FIG. 6, draw out each pole 1 to bring the stay bars 2 and the roof cross braces 3 to spread out, cooperating to FIG. 4 and FIG. 5, meanwhile under the drive of the roof cross braces 3, the side struts 6 will push up the upper bracing ribs 7 until the ventilation roof-boom frame is completely extended out along with the main body stretching to finish pitching the whole tent, as shown in FIG. 1.
