Abstract
The present invention discloses a large-scale inward heel type strut frame for tent, comprising four main poles (1), top brace bars (2), X-bracing linkage groups (3) arranged between each two adjacent pair of poles, each group having two slanting brace linkages crosswise hinged together, and movable sliders (4) movably arranged on the oles, each of which is hinged together with one slanting brace linkage of the adjacent X-bracing bar group; wherein, for the slanting brace linkage of the X-bracing linkage hinged with the movable slider, the length from the junction thereof to the hinge point of the movable slider is greater than that from other junctions thereof to end hinge points.
As a result, after the strut frame is supported and raised, the poles incline inwards which provides stable support, while after being collapsed, the poles can stand vertically so as not to occupy storing space.

Description
AN INTROVERTED TENT FRAME OF LARGE FRAME TENT
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to a tent frame, and more particularly to an intro-s verted tent frame structure in large frame tent.
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to a tent frame, and more particularly to an intro-s verted tent frame structure in large frame tent.
2. Description of Prior Art In accordance with prior art, the conventional large frame tent is similar with the small frame tent in the structure, as shown in Fig. 1 and Fig. 1A, it is typically com-prised of four poles and roof cross braces, between two adjacent poles proper number sets of cross braces are located for facilitating to pitching or striking.
Evidently, the dif ference between them is that there are at least two sets of cross braces set upon the two adjacent poles, after pitching up, the four poles stand on the ground rightly, the two or three sets of cross braces connecting over two adjacent poles are stretched out fully, then over with awning on the located frame to finish a frame tent up.
Obviously said 1 S four poles of the large frame tent bearing the load is much more than a small one, so the so big load exerting on the poles often makes the poles swing, even occur the tent un-stable, especially to the vertical poles.
For overcoming said problem, an introverted tent frame came out, as shown in Fig. 2, after pitching the tent up, the four introverted poles bearing the vertical load make the whole frame more stable than the conventional vertical poles without any swinging. For achieving the introverted poles, the cross brace set is shown in Fig. 2A, in which the hinged immovable ledge of the sliding hub fitting on the pole is stretched out longer than the prior art (comparing to Fig. 1A), so that a bracing strut 31' of said cross brace set 3' is hinged on the outer end of the hinged immovable ledge 41', therefore as 2~ pitching the tent up, the poles are pushed by the sliding hub 4', and tilted out at the feet to form the introverted state at the top end. But this project also has shortcoming: due to the longer hinged immovable ledge 41', the folded framework of the tent appears to in-troverted shape keeping into trapezium small head and big foot, so the volume of folded framework is still bigger than desired, inconvenient for storing.
OBJECTS AND SUMMARY OF THE INVENTION
It is therefore a main object of the present invention to provide an introverted tent frame of large frame tent, in which the poles appears introverted state as pitched up, and appears vertical state as folded up.
For achieving the above-mentioned object, the present invention provides an introverted tent frame of large frame tent, which is typically comprised of four poles and roof bracing struts, between two adjacent poles there are cross inter-pivoted brace sets set upon, said inter-pivoted brace set includes two cross bracing struts;
on the other side, a sliding hub fitting on the pole in movable connection is connected to a bracing strut of the brace set in hinging connection; wherein, on the bracing strut hinged on the sliding hub, the distance from the cross pivoted point to the hinged point of the sliding hub is longer than the distance from the cross pivoted point to the other hinged point of the other bracing strut in the brace set.
In said introverted tent frame of large frame tent, there are at least two cross brace sets between two adjacent poles.
Said bracing strut hinged on the sliding hub is kept that the distance from the cross pivoted point to the hinged point of the sliding hub is longer 2 to 8 cm than the distance from the cross pivoted point to the hinged point of other bracing strut in this set.
As utilizing above-mentioned project, due to the longer distance of the bracing strut hinged on the sliding hub than others, as pitching up the tent, the sliding hub is tilted under the pushing coming from the bracing strut hinged on the sliding hub, further to introvert the pole to stretch out at the foot, so that the whole framework appears in-troverted state for meeting the stable support goal.
As folding up, due to closing bracing struts of the brace sets, the poles is brought to close together, in this time, the longer bracing strut pushes the sliding hub sliding along the pole continuously until the pole is turned to vertical state, so the folded framework appears to square structure, therefore the volume of the folded tent is smaller than the prior art, and save space as storing.

Wherein, said four poles 1 can be telescoped along the axils for further reducing the folded volume; on each pole 1 a sliding hub 4 is attached on in sliding fit, and a radial hinged immovable ledge 41 is extended out from the outside wall for hinging a bracing strut 31 of the cross brace set 3 on;
on the tip end of each pole 1 a static hub 5 is fixed on for hinging the another bracing strut 32 of the cross brace set 3.
Said cross inter-pivoted brace set 3 includes two cross inter-pivoted bracing struts 31 32, and they are respectively hinged on the static hub 5 and the sliding hub 4 with one ends, or pivoted on the another cross brace set 3 end by end.
The difference is that on the bracing strut 31 hinged on the sliding hub 4, the dis-I S tance L 1 from the cross pivoted point to the hinged point on the sliding hub 4 is longer than the distance from the cross pivoted point to the hinged point of another bracing strut 32 of the cross brace set 3, the difference is selected in the range from 2 to 8 cm.
Referring to Fig. 4, as folding up, because the cross bracing sets 3 are closed up, the poles 1 is brought to close to the center too, in this time, the longer bracing strut 31 pushes the sliding hub 4 sliding along the pole 1 continuously until the pole 1 is turned to vertical state, so the folded framework appears to square structure, therefore the vol-ume of the folded tent is smaller than the prior art, and save space as storing.
In the present invention, the number of the cross brace sets depends on the size of the frame tent, as shown in Fig. S; there are three sets 3 setup on between two adja-cent poles 1. it can be another choice, for example, one coordinating sides possess three cross brace sets, and another coordinating sides possess two cross brace sets to structure a rectangular shape frame tent.
Evidently, the dif ference between them is that there are at least two sets of cross braces set upon the two adjacent poles, after pitching up, the four poles stand on the ground rightly, the two or three sets of cross braces connecting over two adjacent poles are stretched out fully, then over with awning on the located frame to finish a frame tent up.
