Trut frame of a tent

Abstract

The present invention provides a tent frame typically comprised of poles and roof braces, and cross bracing struts located between two adjacent poles, and center bracing struts hinged on between the roof brace and the sliding hub of the pole, wherein each roof brace is supported with a center bracing strut, the top end of the center bracing strut is hinged on the roof brace, and the low end is hinged on the cross bracing strut approaching the sliding hub end. The tent frame is more stable and easy to be folding up.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a tent frame. [0003] 2. Description of Prior Art [0004] In accordance with prior art, the conventional structure of foldable tent, as shown in FIG. 1 and FIG. 1A, is typically comprised of four poles 1′ and roof cross braces 2′, between two adjacent poles 1′ proper number of cross bracing struts 3′3″ are located, wherein the cross bracing struts 3′, as shown in FIG. 1, can be directly connected to said adjacent poles 1′ respectively with the both ends by one hinged on a static hub 7′ located on the tip end of one pole 1′, and another end hinged on sliding hub 5′ fitting on another pole 1′ (as shown in FIG. 3), or three pair of cross bracing struts 6′ are set upon, as shown in FIG. 2 (for meeting to the necessary of big scale frame tent); on the other side, a center bracing strut 4′ supporting the roof brace 2′ is hinged on between the roof brace 2′ and the sliding hub 5 with the both...

AI Technical Summary

Benefits of technology

[0008] It is therefore a main object of the present invention to provide a stable tent frame that can be pitched up and folded up easily and smoothly.

[0013] As utilizing above-mentioned project, because the low end of the coordinated center bracing strut is hinged on the cross bracing strut, the center bracing strut is not located in the plane structured by the roof brace and the pole, so that when pitching or folding up, the center bracing strut not only generates support force in the plane structured by the roof brace and the pole, but also exerts side support force to the roof brace so as to keep the roof brace stable without any swinging as in unfolding state, especially to large size of frame tent the support is more stability.

[0014] On the other hand, as folding up, the cross bracing strut can directly draw the center bracing strut bending to the inward, but not via the sliding hub, so the sliding hub bears less force, meanwhile exert more force on the roof brace so as to facilitate to fold up more easily. And the requirement of the material of the sliding hub is relatively reduced, and the production cost is gone down too.

Problems solved by technology

But there are some shortcomings existing in said tent frame as follows: 1. because said center bracing strut 4′ are in a plane structured with said roof cross brace 2′ and said pole 1′, so as pitching or folding up, said center bracing strut 4′ just only exerts supporting effect in this plane, but not generate side supporting force to the roof brace 2′, hence the whole unfolded frame is not stable as expected, especially to the large size tent, this problem is more obviously, due to the more load exerting on the center bracing strut 4′ via the roof brace 2′, the single pressure in this plane often makes the center bracing strut 4′ swing so as to be unstable.
