Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a tent, and more particularly to an umbrella-style top localization mechanism of bell folding tent frame.
  • 2. Description of Prior Art
  • In accordance with the conventional bell tent in umbrella-style, as shown in FIG. 1, a top rib-hub 1 is set upon the central tip end hinging to radial foldable rib set 2 including several folding member bars in each, said member bars in each foldable rib set 2 are connected by connectors one by one for facilitating to fold-up. Said top rib-hub 1 is fixed on the tip end of a pole 3, on which a low sliding rib-hub 4 is fit in moving connection, a radial struts 5 are used for connecting the low sliding rib-hub 4 to the first segment of the folding rib set 2 in hinging connection with the both ends respectively. A spring 6 is put on the stem of the pole 3 and set up between said top static rib-hub 1 and said low sliding rib-hub 4, so that the spring 6 is in compression state as folding up, and as pitching up the tent, the radial rib set 2 is braced up under the restoring force of the spring 6 automatically.
  • But in this case, the pole 3 and said struts 5 and the low sliding rib-hub 4 are below the foldable rib set 2 and covered in the inside occupying a certain space of the tent so that the real valid space of the tent is reduced.
  • Referring to FIG. 2 and FIG. 3, another prior art is shown, in which the top static rib-hub 1 is located on the central top hinged with the struts 5, the pole 3 is connected to the bottom side of the top static rib-hub 1 with the tip end in dead joint, as the same the low sliding rib-hub 4 is fit on the pole 3 in moving connection, said low sliding rib-hub 4 is used for hinging to the radial foldable rib set 2 including several folding member bars in each, said member bars in each foldable rib set 2 are connected by connectors one by one for facilitating to fold-up. And the outer end of said struts 5 is hinged on the first segment of the foldable rib set 2. Spring 6 is put on the stem of the pole 3 and set up between said top static rib-hub 1 and said low sliding rib-hub 4, so that the spring 6 is always in stretching state whatever the tent is pitched up or stroke up. On the other hand, an elastic pawl 7 is built upon the pole 3 approaching to the bottom end, coordinating to it, the low sliding rib-hub 4 has a locking hole 41 drilled on the low portion for catching up said elastic pawl 7 to locate the low sliding rib-hub 4 on the pole 3.
  • As the same, as folding up, just need to press down the elastic pawl 7 locking on the locking hole 41 of the low sliding rib-hub 4 lightly to release the lock so that the low sliding rib-hub 4 can be pushed up closing all the radial foldable rib sets 2 to the pole 3; as pitching up the tent frame, just need to pull down the low sliding rib-hub 4 along the pole 3 until the locking hole 41 of the low sliding rib-hub 4 is launched by the elastic pawl 7, meanwhile cooperating to the struts 5 hinged on the top static rib-hub 1, all the radial foldable rib sets 2 are braced up. So the bell tent is to be pitched up or folded up easily and simply, and the pitch-up tent is so stable under the supporting coming from the struts 5, and the use function is fully brought up. On the other hand, the main supporting framework composed of the foldable rib sets 2 is below the struts 5, so that the pitch-up tent has a smooth inside surface in a full dome, and evidentially bigger space.
  • According to above description, we can find shortcoming existing in the conventional bell folding tent, such as because said spring 6 is set up between the top static rib-hub 1 and the low sliding rib-hub 4, and fixed on them with the both ends respectively, as in folding state, the low sliding rib-hub 4 is pulled up so close to the top end by the spring 6 that the user needs to exert bigger force to pull it down overcoming the elastic force of the spring 6 until the locking hole 41 is launched by the elastic pawl 7 as tending to pitching it up, therefore this operation will bring to inconvenient to the user.
    • OBJECTS AND SUMMARY OF THE INVENTION
  • It is therefore a main object of the present invention to provide a top localization mechanism of bell folding tent that not only provides a bigger inner space, but also facilitates to operate in pitch-up process saving labor.
  • For achieving the above-mentioned object, the present invention provides a resolution, in which a top static rib-hub is set upon the tip center of the frame, and hinged to radial struts respectively, and fixed on the tip end of a pole holding a low sliding rib-hub on the stem vertically, and said low sliding rib-hub is hinged to a proper number of radial foldable rib sets; wherein, said pole has a hollow inner and two opposite guide slots, thereby setting a slider in the inner hollow of the pole, a set pin penetrates through the slider and said opposite guide slots to be fixed on the low sliding rib-hub with the both ends; a spring is set up in the hollow inner of the pole between the top static rib-hub and the slider, and is in compression state as folding up the tent frame.
  • Said pole has a location mechanism at the lower portion for locating the low sliding rib-hub on.
  • As utilizing above-mentioned project, due to the struts on upper and the main framework on below, the pitch-up tent appears to smooth inner surface in a full dome with a bigger space. And because the spring is in compression state as the tent is in folding state, the low sliding rib-hub is located on a lower position under balance force coming from the spring, so that the user just need to hold two radial foldable rib sets to shake slightly, the low sliding rib-hub will slide down under the restoring force coming from the spring to spread all the radial foldable rib sets out, in this time, just pull the low sliding rib-hub down continuously sliding along the pole lightly to get the locking position so that the elastic pawl launches into the locking hole in lock state, meanwhile the whole tent frame is pitched up completely, the all operation is easy and simple.
