Of course, the inner diameter of the first pipe portion 137 and the second pipe portion 138 may be the same or different. The second pipe portion 138 of the second member 136 is provided with a ball biting in the spiral groove 132 of the first member 131, which will be described in more detail later. Of course, helix may be installed instead of the ball.

That is, the second member 136 moves closer to or away from the body 110 while moving along the first member 131 according to the rotation direction of the first member 131.

The first member 131 and the second member 136 as described above may be replaced in some cases. In addition, the number of poles 130 can be adjusted to less than five or six or more if necessary.

At the end of the second member 136, the folding member 150 is installed through the connector 140. The connector 140 may be used in any other form as long as the folding member 150 is connected to the second member 136 so as to be folded in one direction. Folding member 150 is to be folded in one direction, that is, upward in the unfolded state. Although this folding member 150 is not necessarily required, it is preferable to install the folding member 150 in order to reduce the size of the framework in the folded state. A ring 152 is installed at the end of the folding member 150. The ring 152 is to be able to prevent the second member 136 is rotated by binding to the necessary portion when the folding frame apparatus 100 according to the present invention is used in the skeleton, such as a tent.

The body 110 as described above is equipped with a rotation driving means 160. The rotation driving means 160 is for rotating the first members 131 of the pawl 130 at the same time, and includes a driving bevel gear 161 mounted to the first gear groove 112. The driving bevel gear 161 has gears 164 formed along the upper edge thereof, and a rotating shaft 162 extending downward from the center of the bottom thereof is coupled to the through hole 114 to protrude outward. The rotational power input unit 163 is coupled to 162 and fixedly integrally with the rotational power input unit 163 through the screw member 165. The rotational power input unit 163 here is in the form of a handle for manually rotating the drive bevel gear 161. In some cases, it may be configured in the form of inputting the rotational force by using a power such as a motor. The stopper 163b is coupled to the rotational power input unit 163 through a screw hole 163a. The stopper 163b is for preventing the driving bevel gear 161 from rotating in a specific state such as a tent installed by being coupled to a groove or a hole 112a formed in the bottom surface of the first body 111. The stopper 163b is not necessarily required when the reaction force of the pawl 130 is small or has a reverse rotation prevention function at another part, but is preferably provided. Of course, the stopper 163b may be configured in any other structure such as a push button method of a ballpoint pen.

The driven bevel gears 166 are installed in the second gear groove 113 and the third gear groove 122. These driven bevel gears 166 are rotated at the same time by the rotation of the driving bevel gear 161, and have a hemispherical shape as a whole, and gears 167 are formed along the edge of the cross section. The driven bevel gear 166 is screwed with a first member 131 as one component of the pole 130. The connection form of the driven bevel gear 166 and the first member 131 may be changed to another form, and may be formed integrally with the first member 131 in some cases. Here, the driven bevel gear 166 is formed in a hemispherical shape to be able to swing smoothly without shaking in the range of about 90 degrees with the pole 130 connected to it. Of course, in some cases, the driven bevel gear 166 may be left as it is, and the first member 131 may be foldably connected, but in this case, the arrangement diameter of the poles 130 in the folded state is increased. This is also the case when using a general bevel gear and a universal joint. The rotary drive means 160 and the body 110 can be seen as one rotary drive module having a function of simultaneously rotating those connected to the driven bevel gear 166. This rotary drive module can be used in other devices.

5 is an enlarged cross-sectional view showing the inner coupling structure of the pole.

As shown in FIG. 5, the pole 130 has a fin-shaped first member 131 having a spiral groove 132 formed along an outer circumferential surface thereof and a tubular second member coupled to an outer circumferential surface of the first member 131. 136. The second member 136 is installed at one end of the first pipe part 137 and the first pipe part 138 having a small outer diameter, and the second pipe part having a thickness and an outer diameter greater than the first pipe part 137 and a ball 139 is installed. (138). The ball 139 forms a hole 139a which communicates with the inside of the second pipe part 138, and after inserting the ball 139 and the spring 139b in this order, the hole (139c) from the outside into the hole ( 139a) may be installed in a blocked form. It is preferable to install two or more balls 139. Preferably, the ball 139 is installed in an appropriate number in consideration of the size of the spiral groove, the smooth operation of the rotation driving means, and the reverse rotation of the driving bevel gear due to the reaction force of the pole. It is.

The pitch of the spiral groove 132 can be adjusted as needed, but when the pitch is increased, the moving distance of the second member 136 by the first rotation is increased instead of entering a lot of force to rotate the rotary power input unit 163 once. Grows On the other hand, when the pitch of the spiral groove 132 is reduced, less force is required to rotate the rotational power input unit 163, but the movement distance of the second member 136 by one rotation becomes smaller.

6 is a perspective view of an expanded state of the tent according to the present invention, Figure 7 is an enlarged perspective view of a folded state of the tent according to the present invention.

As shown in FIG. 6, the tent 200 according to the present invention includes a body 110 provided with the rotation driving means 160 described above, and poles 130 installed at predetermined angles on the body 110. . The pole 130 is connected to the driven bevel gear 166 inside the body 110 and has a tubular shape that can accommodate the first member 131 and the first member 131 having the spiral groove 132 on the outer circumferential surface thereof. As described above, a second member 136 having a ball 139 bited into the spiral groove 132 is formed therein. The folding member 140 is installed at the lower end of the second member 136. The folding member 150 is connected to the second member 136 through the connector 140 so as to be folded upward in an unfolded state. A ring 152 is formed at the end of the folding member 150. The connecting line 170 is inserted into the ring 152. This limits the bottom diameter of the tent 200 and serves to prevent the second member 136 from rotating. To prevent the rotation of the second member 136 and the folding member 150 may be used in other forms.

The fabric 180 surrounding the space in the form of the pole 130 is formed inside the pawl 130 and the folding member 150 through the pawl 130 and the folding member 150 and It is connected to the body portion 110. The ring portion 182 may be configured in the form of a tube.

The folded state of the tent 200 as shown above is shown in FIG. As can be seen in Figure 7, the tent 200 according to the present invention can be folded in the form of a small bar, only the rotational power input unit 163 is exposed to the outside in the folded state, the rest by the bottom of the fabric 180 Obscured

Referring to the process of hitting and folding the tent 200 according to the present invention described above are as follows.

First, the pawl 130 and the folding member 150 are unfolded in a state as shown in FIG. 7. Accordingly, the driven bevel gear 166, which has been erected, is also placed horizontally while standing, and the gear 167 formed at the edge of the cross section thereof is bitten by the gear 164 of the driving bevel gear 161. At this time, the pole 130 and the folding member 150 is bent like a bow by the weight of its own and the weight of the fabric 180, the end side of the folding member 150 sags downward. In this state, when the rotational power input unit 163 is rotated in one direction, the driving bevel gear 161 is rotated, and the driven bevel gears 166 that are being bitten by the driving bevel gear 161 are also simultaneously rotated in the same direction. Accordingly, the first members 131 connected to the driven bevel gears 166 are simultaneously rotated in the same direction. The second member 136 and the folding member 150 is in a state where the rotation is prevented by the connecting line 170 connected to the end of the folding member 150.

Accordingly, the second member 136 moves away from the body 110 along the first member 131, so that the length of the pole 130 becomes longer. Since the end of the folding member 150 is limited in diameter by the connecting line 170, the pawl 130 and the folding member 150 is gradually bent, and eventually the state as shown in FIG. After fully unfolding the tent 200, the stopper 163b is operated as necessary to prevent the driving bevel gear 161 from rotating.

That is, in the tent 200 according to the present invention, after the pole 130 and the folding member 150 are opened, the tent 200 is installed by simply rotating the rotational power input unit 163.

The process of folding the tent 200 consists of the reverse process of the process of hitting the tent 200. That is, in the state of FIG. 6, when the lock state of the stopper 163b is released and the rotational power input unit 163 is rotated in the opposite direction from the beginning, the driving bevel gear 161 and the driven bevel gears 166 are opposite to the first. Direction, and the first member 131 is also rotated in the opposite direction from the beginning. Since the first member 131 and the folding member 150 are prevented from being rotated by the connecting line 170, the second member 136 moves toward the body 110 by riding the first member 131 to form the pole 130. ) Length decreases gradually. When the folding member 150 is folded in the state where the length of the pool 130 is sufficiently reduced, and each pole 130 is erected, it becomes a state as shown in FIG. In the state as shown in Fig. 7, it is possible to carry or store the bag by tying its upper end with a string.

That is, the tent 200 according to the present invention does not have a connection or disassembly of accessories, there is no fear of missing parts, it is very easy to hit or fold the tent 200.

As can be seen from the above description, the hemispherical gear according to the present invention allows the second gear groove and the third gear groove formed on the body to be rotated or swinged in place while allowing the pole to be folded or unfolded smoothly. To make it happen. In addition, the hemispherical gear according to the present invention allows the folding bevel gear and the volume of the tent using the same by allowing the bevel gear itself to swing to reduce the diameter of the poles are arranged in the same direction by folding the driven bevel gear itself To reduce it.

Since the length of the pole according to the present invention is adjusted by the rotational motion of the first member to avoid the hassle of removing the pole when hitting or dismantling the tent, etc., the length of the plurality of poles at the same time Allows adjustment In particular, the pole according to the present invention when the ball is installed inside the operation is made very smoothly.

Folding frame apparatus and tent using the same according to the present invention can be folded or unfolded as it is without disassembling or assembling parts, so there is little risk of missing parts, and can be folded or unfolded by rotating the rotating power input unit, which is very easy to use. It is convenient. In addition, it is easy to transport and store because of its small volume and small bar shape when folded.
