Description

  The present invention relates to a tent structure and to a push pole type tent frame.

  With the spread of private cars, going out by car has become a new style of travel. In order to enhance the convenience of going out by car, products used for cars attached to cars began to be developed, and car tents were born in such an environment.

  A car tent is a tent that can be installed on the hood of a car. When in use, it does not touch the ground like other tents, making it difficult for moisture on the ground to enter and is relatively comfortable.

  In general, a tent frame of a conventional vehicle tent is configured by connecting a large number of frame poles. For the convenience of folding the tent, each frame pole is movably connected through a joint or the like. In order to expand the tent, a fixed structure will be installed. When the tent is expanded or folded, it is often necessary to operate each joint or fixed structure. Therefore, the operation process is troublesome, takes a relatively long time, and is very inconvenient to use.

  In response to the above situation, semi-automatic or fully automatic folding / expanding hood tents for vehicles have been developed. As shown in FIG. 1, the automatic tent filed by the present applicant disclosed in Patent Document 1 controls sliding on the base of the bottom end of the central support pole 23 ′, and the free end of the tow rope 31 ′ is centered. It is connected to the bottom end of the support pole 23 'and drives the winding or quick release of the rope reel 32' using a driving device to realize folding or unfolding with respect to the tent.

A push pole type tent frame according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 2-7, the tent frame of one Embodiment of this invention is provided with the base 1, the tent frame pole 2, and the control mechanism.

  The base 1 has a frame structure and can be installed on the ground or fixed to the hood of an automobile.

  The tent frame pole 2 includes two sets of support pole units 20 installed in parallel on the left and right sides of the base 1, and a reinforced horizontal pole 24 is connected between the two sets of support pole units 20. The two sets of support pole units 20 each include a support pole 21, an upper support pole 22, and a lower support pole 23 that are movable and connected to each other in order. The opposite end of the support pole 21 is movably connected to the front end of the base 1, and the opposite end of the lower support pole 23 is movably connected to the rear end of the base 1. The base 1, the support pole 21, the upper support pole 22, and the lower support pole 23 form a shape similar to a triangle when the tent frame is deployed.

  The control mechanism includes a telescopic push pole mechanism 3 that is movably connected to the two sets of support pole units 20 and includes a driving device. One end of each telescopic push pole mechanism 3 is movably connected to a position close to the rear portions of the left and right sides of the base 1, and the opposite end is movably connected to the upper support pole 22 or the lower support pole 23.

  Each telescopic push pole mechanism 3 includes a seat pole 31 and a push pole 32 that performs telescopic motion in the seat pole 31, and further includes a drive device 33 that drives the push pole 32 and moves the seat pole 31. The driving device 33 in this embodiment is installed below the seat pole 31. The drive device 33 is a motor.

  The lower end of the seat pole 31 is movably connected to the bottom base 1 through the fixed base 34. The upper end of the push pole 32 can be movably connected to the upper support pole 22 or the lower support pole 23 through the connecting base 35, and can be movably connected to a movable connection module in which the lower support pole 23 and the upper support pole 22 are movably connected. .

  The tent frame pole 2 further includes a sub support pole 25. The sub-support pole 25 is a U-shaped curved pole, and both ends of the sub-support pole 25 are movable in one direction on the upper support pole 22 or movable on a movable connection module in which the lower support pole 23 and the upper support pole 22 are movably connected. Connecting. In this way, the tent apex portion after the tent frame is developed is rounded. As used herein, “movable connection in one direction” means that the sub-support pole 5 has a constant angle in the counterclockwise direction relative to the upper support pole 22, such as the included angle close to 90 degrees in the present embodiment. This means that only deployment is possible. If the deployment angle is excessive, the effect of tightly tensioning the tent apex cannot be achieved.

  As shown in FIGS. 2 and 3, when the tent frame of the present invention is in the folded state, each pole is in contact with the base 1. The push pole 32 of the telescopic push pole mechanism 3 is housed in the pole 31.

  At the time of deployment, when the dynamic drive device 33 is operated, the push pole 32 is driven and extends outward with respect to the seat pole 31. According to the extension of the telescopic push pole mechanism 3, as shown in FIGS. 4 and 5, the lower support pole 23 and the upper support pole 22 are lifted upward together, and at the same time, until the push pole 32 moves to a predetermined position. Lift the support pole 21 upward. Thus, each support pole of the tent frame is fully expanded (see FIGS. 6 and 7).

On the other hand, when the tent is folded, the drive device 33 is activated and operated in reverse. The push pole 32 is pulled and moved so as to be stored in the seat pole 31. As a result, the push pole 32 loses its push-up action with respect to the lower support pole 23 or the upper support pole 22, and each pole is directed downward by the action of gravity until each support pole is completely folded. Thus, the tent is in a folded state.

  In the present invention, the expansion / contraction of the tent frame is performed by using the drive of the length change of the telescopic pole through the telescopic push pole mechanism 3 having the driving device 33 movably connected to the two support pole units 20 of the tent frame. The structure of the tent frame to control the change and thus use on the hood of the car becomes simpler.

  In addition, the structure of the telescopic pole not only has a shorter movement route than the conventional pulling rope, but also has superior structural strength, effectively guaranteeing the stability and reliability of the performance of the push pole type tent frame. be able to.

  By summing up the descriptions of the above embodiments, the operation, use, and effects of the present invention can be fully understood. However, the embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the claims of the present invention. In other words, all simple changes and modifications having the same effect shall fall within the scope of the present invention based on the content of the claims and the description of the present invention.
