Description

FOLDING TENT REINFORCEMENT

The present invention relates to a tent structure, especially a foldable tent frame. To assemble a conventional tent, two or more people are needed to collaborate and finish the assembly, which is not practical. As a result, it is necessary to improve its structure. According to Figure 1, Chinese Patent No. 23238607.9 has proposed a foldable tent frame, which comprises four upper poles 1 ', two intermediate poles 2', two lower poles 3 ', a connecting rod 4', an intermediate connecting support 5 ', a lower connection support 6', a rotary hook 7 ', and a plurality of loops 8'. The four upper poles 1 'are symmetrically connected to the connecting rod 4'. The two intermediate poles 2 'are symmetrically connected to the intermediate connecting support 5'. The two lower masts 3 'are symmetrically connected to the lower connection support 6'. The intermediate connecting support 5 'and the lower connection connector 6' are coordinated with the connecting rod 4 '. The rotary hook 7 'is arranged on the lower support 6'. The loops 8 'are disposed on the joints of the upper poles 1'. The two intermediate poles 2 'of the conventional tent frame are articulated to the intermediate portion of the upper poles 1'. After deployment of the tent, the rotary hook 7 'is adapted to fix the tent frame, which adds a working procedure in use. The main objective of the present invention is to provide a foldable tent frame whose structure 1 and assembly are simple, and have a better rigidity. The present invention relates to a foldable tent frame, characterized in that it comprises an upper connection support, a guide mast, a plurality of poles, a plurality of first support poles, an intermediate connection support, a a plurality of second support posts, and a lower connection support; each mast having an inner end articulated to the upper connection support, the guide post having an upper end attached to a lower surface of the upper connection support and a lower portion extending downwardly; each first support mast having an inner end articulated to the intermediate connection support and an external end hinged to the inner end of one of the plurality of masts, the intermediate connecting support having an intermediate guide hole for the insertion of the mast a guide, the intermediate connection support being thus able to move upwards or downwards along the guide-mast; each second support pole having an inner end hinged to the lower connection support and an outer end articulated to an intermediate portion of one of the plurality of masts, the lower connection bracket having an intermediate guide hole for insertion of the guide pole, the lower connection support being thus able to move upwards or downwards along the guide mast. According to a preferred feature, the foldable tent frame further comprises internal hinge joints, each inner hinge joint being L-shaped and having an inner end articulated to the upper connection support, an outer end connected to the inner end of the one of the plurality of masts, and a transverse projection, the outer end of each first support mast being articulated to the transverse projection. According to a preferred feature, the folding tent frame further comprises intermediate hinge joints, each intermediate hinge joint being attached to the intermediate portion of one of the plurality of masts and having a transverse projection, the outer end of each second support mast being hinged to the transverse projection. According to a preferred characteristic, the plurality of poles is four in number, the plurality of first support poles is two in number, and the plurality of second support poles is four in number.

As a result, each first support mast has its internal end hinged to the intermediate connection support and its external end hinged to the inner end of one of the plurality of poles. The first support posts provide an outward support action between the intermediate tie support and the masts to ensure that the tent will not be folded automatically after the tent is deployed, without the use of tent frame hooks. conventional. The present invention is simple in structure and assembly, and has a better rigidity because there are four second support poles. In addition, the present invention improves the tent frame so that a person can deploy and fold the tent, which is very convenient.

To better illustrate the object of the present invention, will be described below an embodiment with reference to the accompanying drawings. On these drawings. Figure 1 is a perspective view of a conventional tent foldable frame;

Figure 2 is an exploded view of an embodiment of the present invention;

Fig. 3 is a sectional view of an embodiment of the present invention;

Figure 3a is a sectional view of an intermediate connection support of the embodiment of the present invention;

Figure 3b is a sectional view of a lower connection support of the embodiment of the present invention;

Figure 4a is a schematic view of the embodiment of the present invention in a fully deployed state;

Figure 4b is a schematic view of the embodiment of the present invention in a partially deployed state; and Figure 4c is a schematic view of the embodiment of the present invention in a folded state. According to Figure 2, a foldable tent frame 30 according to one embodiment of the present invention comprises an upper connection support 1, a guide pole 2, four poles 3, two first support poles 4, internal hinge joints 5 , an intermediate connection support 6, four second support poles 7, intermediate hinge joints 8, and a lower connection support 9. Each mast 3 has an internal end hinged to the upper connection support 1. The guide mast 2 has an upper end attached to a lower surface of the upper connecting support 1 and a lower part extending downwards. Each inner hinge joint 5 is L-shaped, and has an internal end hinged to the upper connection support 1, an outer end connected to the inner end of one of the four masts 3, and a transverse projection 51. Each first support pole 4 has an external end hinged to the transverse projection 51 and an inner end hinged to the intermediate connecting support 6. The outer ends of the two first support posts 4 are articulated to the inner ends of the two symmetrical masts 3 of the four masts 3. The support Intermediate connection 6 has a guide hole 61, according to Figure 3a, for the insertion of the guide-mast 2, so the intermediate connecting support 6 is able to move up and down along the mast. guide 2. When the intermediate connecting support 6 is moved up or down along the guide mast 2, the first support posts 4 are connected to fold or to extend the mast 3. Each hinge joint 8 is attached to an intermediate portion of one of the masts 3, and has a transverse projection 81. Each second support mast 7 has an external end hinged to the transverse projection 81, so the four second masts of support 7 have their outer ends articulated to the intermediate part of the four masts 3. Each second support post 7 has an internal end hinged to the lower connection support 9. The lower connection support 9 has an intermediate guide hole 91, according to the 3b, for insertion of the guide post 2, therefore, the lower connecting support 9 is able to move up or down along the guide post 2. According to FIG. 4a, the intermediate support of FIG. connection 6 and the lower connection support 9 are fixed to the guide post 2 movably. When the intermediate connecting support 6 and the lower connecting support 9 are moved upwards along the guide mast 2 to abut against the upper connection support 1, the tent is in a fully deployed state. According to FIG. 4b, the intermediate connecting support 6 is moved downwards along the guide mast 2 and the lower connecting support 9 is released from the guide mast 2 to fold the tent gradually. According to FIG. 4c, the intermediate connection support 6 is moved farther downwards along the guide mast 2 and the lower connection support 9 is distant from the upper connection support 1, so the tent frame is completely folded . Although some embodiments of the present invention have been described in detail for purposes of illustration, various modifications and improvements may be made within the scope of this invention.
