Description

Frame structure of auto-umbrella type tent

The present invention relates to a frame structure of an umbrella-type automatic tent that allows the tent cloth body and the tent frame to be unified and folded quickly and easily using the principle of the umbrella.

In general, tents are used during outdoor activities in nature. Recently, automatic tents that can be automatically installed and dismantled without assembling structures such as poles are widely used.

Such automatic tents are also commonly used as folding tents or bellows-type tents, which are simply unfolded to form a dome by simply throwing a tent into the place of installation, and simply folding the tent without disassembling the members. It can be called a tent that greatly increases the user's convenience because the volume can be minimized only by folding and completing the installation and dismantling of the tent within a short time.

Examples of such automatic tents include those disclosed in Korean Utility Model Registration 0223717, Utility Model Registration 0339799, Utility Model Registration 0344232, and Korean Utility Model Registration 20-0359030 (designated name: umbrella type automatic tent frame). These are the so-called umbrella (folding) tents, which have a structure and operation similar to that of umbrellas to enable the installation and dismantling of tents, which resemble the shape of an umbrella and thus form a folding structure at the top of the frame. A plurality of main pole poles are radially bound so that they can be rotated. A center pole is connected to the lower part of the main shaft so that the support shaft moving up and down along the center pole is penetrated. The main pole pole and hinge are connected to the support shaft. The supporting pole is radially bound so that it can rotate, and the top of the tent cloth The bottom bottom edge of the tent and the bottom end of the main pole are tied together, and the tent frame and tent cloth body are integrated. In particular, as an important common point of the above-mentioned pre-registration designs, as shown in Figure 11 to apply the principle of the automatic umbrella to more easily open and fold the tent springs having a straight elastic resilience to the center of the tent (1) 3) by using the elastic restoring force of the spring (3) in the vertical movement of the slide actuator (4) to the tent structure is automatically unfolded.

Accordingly, the above-described designs, when the tent is applied to the center side to retract the pole 7 when the tent is folded, the hollow slide actuator 2 compresses the spring 3 along the center stage 1. As the pole is lowered, the pole 7 and the support 6 are placed in a straight line in a substantially vertical direction and folded like an umbrella. When the tent is installed, the slide actuator 2 is pushed by the elastic force of the compressed spring 3. The pole pole 7 is extended in the horizontal direction so that the tent is installed. In this way, the installation of the tent is completed, so that the elastic means 3 are in a relaxed state.

However, all the above-described prior art uses the spring as a means for the automatic unfolding of the tent has been raised the following problems.

When the tent is thrown into the installation place to install the folded tent, the binding force on the compressed spring 3 is released and the slide actuator 2 is raised by the elastic force of the spring, thereby folding the pole 7 The tent is installed in the form of a dome, the spring (3) is in a relaxed state under this state, the tent is not maintained in a tight installation state, the tent cloth (8) is fluttered in the wind, the noise is severe, The installed tent is not strong and not only has a lot of rumble, but also has the disadvantage that there is no function to properly adjust the tension of the tent cloth (8) according to the situation.

On the other hand, as shown in Fig. 12 showing the design disclosed in Korean Utility Model Registration No. 20-0359030, the cylindrical body in the radially connected to the outer periphery of the cylindrical body (10, 13), respectively, to the outer periphery of the cylindrical body (10, 13) The opening grooves 17 and 18 of the pole poles 11 and 12 are fitted to the two projections 15 and 16 protruding at each incision of each of the incisions (10) and (13). The method has a high possibility that the poles 11 and 12 are easily detached from the protrusions 15 and 16 by the action of an external force, so that the tent may collapse, and instead of the protrusions 15 and 16, the cylindrical bodies 10 and 13 may be used. The outer periphery of) is wrapped around the wire, but the pole poles (11, 12) through the wire through the body threaded through all the poles that are arranged radially when twisting both ends of the wire has been widely used, In this case, if the pole is damaged and needs to be replaced, unscrew the wire and remove the whole pole. I have had the inconvenience of having to be re-assembled.

In summary, the existing automatic tents are mostly made of steel wire or FRP poles, so they are vulnerable to rain when the tents are installed, especially when they are folded, they are bulky and not easy to carry. It is pointed out that most of the existing automatic tents require semi-automatic operation such as pulling a string from the top or pushing them down from the bottom when installing the tent. In this case, the fabric of the tent is inflated, which shortens the life of the fabric. In this case, it is necessary to reduce the tension of the tent in consideration of the expansion of the fabric. Need to be kept taut, but in the prior art the weather There was no ability to adjust the tent tension depending on the situation.

Accordingly, the present invention has been proposed in view of the above points, and its purpose is to automatically maintain the tent after the tent is automatically installed, or to adjust the tension of the tent to suit the weather conditions. To provide a structure.

In this case, the slide hollow shaft member 105 and the nut member 108 have a polygonal cross-sectional structure (for example, an octagonal shape that is close to a circular shape) so that the nut member 108 does not drift together with the screw shaft 107. (The central hollow shaft member 103 also has the same polygonal shape), so that the nut member 108 is lowered by the elastic means 110, for example, the support member 109 when the nut member 108 is lowered. The lower end of the screw shaft 107 extending below the support member 109 is provided with a stopper 134 having a larger diameter than the hole of the support member 109. The rise of the slide hollow shaft member 105 is limited to a certain height.

In addition, one or more first and second extension poles 135 and 136 are connected to the ends of the main pole poles 104 by using connecting portions 137 and 138 having a structure allowing folding and unfolding. Reference numeral 138 is a substantially similar structure except for some differences in appearance from the connection part 132 of the support pole 106, so the detailed structure of the connection part 137 will be described below.

As shown in FIG. 8D, the connecting portion 137 is provided with a fixing member 141 having a slide space 140 between both side walls 139 and 139, and a folding and unfolding with respect to the fixing member 141. Consists of a movable member 142 connected in a rotational hinge structure, the hinge pin 143 is installed across the side walls 139, 139, the hinge pin 143 is the movable member 142 Is fastened through the long hole 144 formed in the, the movable member 142 can be moved along the slide space 140 within the length range of the long hole 144, the movable member 142 is When the rod is pushed in a straight direction to enter the slide space 140 deeply, the hinge pin 143 is caught by the left end of the long hole 144 based on the illustrated state, in which the movable member 142 is The pivoting operation around the hinge pin 143 is not allowed, and this state is the tent 100 Becomes a stretched state is installed (see Fig. 2, Fig. 8b).

Meanwhile, when the tent 100 is folded, the movable member 142 is pulled out, whereby the movable member 142 is moved so that the hinge pin 143 is located at the right end of the long hole 144. State (see Fig. 8A).

In this state, since the movable member 142 is pivotable with the hinge pin 143 as the center point, when the movable member 142 is bent with respect to the fixing member 141, the movable member 142 is bent as shown in FIG. 8C. The connection part 137 is folded as shown in FIG. 1 so that the extension poles 135 and 136 are collected side by side.

The fixing member 141 and the movable member 142 are provided with elastic pieces 145 and 146 having arrowhead shapes, respectively, and the elastic pieces 145 and 146 are connected to the connecting members 147 and 148. (The connecting members 147 and 148 have the same structure as the connecting member 120 shown in Fig. 7), and the pole poles 135 and 136 are fitted to the connecting members 147 and 148, respectively. It consists of a structure for connecting.

Here, the elastic connector spring 149 is further provided with an elastic plate spring 149 as shown in Figs. 9 (a, b), so that the hinge pin 143 is always provided with a long hole 144. Configuring the force to push on the right side of the pole helps to fold or unfold the poles automatically. Accordingly, when the poles are folded, the second extension pole 136 can be easily folded as shown in FIG. 9A by the force of the elastic plate spring (made of thin elastic plate or elastic steel wire having a diameter of about 1.5 mm). When installed, the force is applied to the spring 149 by the elasticity of the tent cloth 150, and as shown in FIG. 9B, the lock becomes a state where the pole is not folded so that the tent can be firmly held.

Therefore, the connection part 137 is preferably provided with a locking configuration (143, 144, 149), while the connection parts (132, 138), if there is a locking configuration, rather the problem that the poles are folded and does not have a locking configuration.

Hereinafter, the operation process of the present invention will be described in detail.

Frame structure 101 of the automatic umbrella type tent 100 of the present invention is put in a separate case cover in a folded state as shown in Figure 1 is stored to be kept in a folded state minimum volume, when installing the tent 100 Peel off the case cover, and throw the tent 100 in the installation place, the tension regulator 102 is released to restrain the tent 100 is unfolded.

That is, in the state in which the tent 100 is folded and wrapped, the slide hollow shaft member 105 is lowered so that the two cylindrical bodies 112 and 128 are in contact with each other, and the elastic means 110 is in close proximity to each other. 109 and the nut member 108 is in the maximum compressed state, the slide hollow shaft member 105 is pushed by the elastic force action of the elastic means 110 that was compressed at the moment the external force forcing the folding is removed. It will be lifted up.

As the slide hollow shaft member 105 rises, both side cylindrical bodies 112 and 128 are opened, and the support pole 106 in the substantially vertical direction pulls the main pole pole 104 to pull the main pole pole 104. It will be raised close to the horizontal, the support pole 106 and the main pole 104 to form a triangular structure is to install the tent 100 as shown in Figs.

However, in the state in which the tent 100 is installed, the compression spring 110, which is an elastic means, is elongated as shown in FIG. 3, and thus the tent cloth 150 is maintained in tension because the main pole 104 cannot be pulled with a strong force. In the following there is a problem that the tent cloth 150 is so weak that the tension received from the compression spring 110, the tent is rocking.

At this time, the present invention is to adjust the tension of the tent cloth 150 to an appropriate level through the adjustment of the tension adjusting unit 102. To this end, the nut member 108 is lowered to rotate the handle 133 of the screw shaft 107 to compress the compression spring 110, the nut member 108 is lowered to the compression spring 110 ), The slide hollow shaft member 105 is first lifted by the elastic force to expand the compression spring 110, and the stopper 134 at the lower end of the screw shaft 107 is caught by the support member 109. When supported, the slide hollow shaft member 105 stops further rising, and afterwards, the compression spring 110 is compressed by the descending nut member 108, and this compression force strongly increases the main pole pole 104. By pulling the slide hollow shaft member 105 to fall up and down while pulling to maintain the tent cloth 150 in a tense state.

However, if it is determined that due to the very hot weather caused the expansion of the tent cloth 150 and the excessive tension acts on the tent cloth 150, in this case by rotating the screw shaft 107 of the tension control unit 102, the nut member 108 As a result, the elastic force of the compression spring 110 that extends is lowered, thereby reducing the tension acting on the tent cloth 150 to prevent the tent cloth 150 from being damaged by excessive tension.

However, if the temperature of the tent fabric 150 occurs due to low morning or rainy weather, at this time, the nut member 108 is lowered to compress the compression spring 110, and accordingly the elastic force of the spring Due to the increase, the tent cloth 150 is kept taut.

On the contrary, when the tent 100 is dismantled, first, the nut member 108 is raised so that the compression spring 110 is stretched, and the force pole is applied to hold and hold the main pole poles 104 on both sides that are horizontally spread. The slide hollow shaft member 105 is lowered in conjunction with the downward movement of the 106, and when the cylindrical bodies 112 and 128 on both sides approach each other, the main pole pole 104 is shown as shown in FIG. ) And the support poles 106 are gathered neatly and folded state, wherein the compression spring 110, which is an elastic means, is compressed to accumulate elastic force therein and then automatically expands the tent when the tent 100 is installed. It is a circle, and the tent is folded and stored in the case.

On the other hand, in the embodiment of Figure 1 is installed so that the tension adjusting unit 102 is located outside the tent 100, in the case of another embodiment of the present invention shown in Figure 10 the tension adjusting unit 102A is a tent ( It is installed to be located inside the 100A), the external installation method is suitable when the height of the tent is low, the installation method inside the tent is suitable when the height of the tent is high. However, in the tension adjusting unit 102A of FIG. 10, the vertical hollow positions of the slide hollow shaft member 105A and the central hollow shaft member 103A are opposite to those of FIG. 3, and the main pole pole 104A is the central hollow shaft member ( 103A) is connected to the lower end, except for the difference that the support pole 106A is mounted to the lower end of the slide hollow shaft member 105A, the technical configuration is substantially the same as the embodiment of FIG.
