Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a folding tent, and particularly to a simple assembly structure for a gathering tent that can be assembled in a plaza or the like to allow a large number of people to gather.

[Prior Art] A so-called gathering tent is used to construct an event space where a large number of people can gather by assembling it in a plaza, etc. Therefore, it is always easy to assemble and disassemble and store it in a short time. It is desirable to have something that is easy to do.

However, in the past, members constituting a gathering tent were constructed by connecting multiple frames to each other, and then tying tent cloth onto the frames with strings. It required time and effort. In addition, the frame, which is a component part, must be provided with various lengths, and furthermore, because of its large size, it is not possible to tension the tent cloth with sufficient tension.

Furthermore, as mentioned above, since there are a large number of parts such as frames, parts may be damaged or lost during storage and transportation, and parts must be repaired or replenished during assembly.

For the reasons mentioned above, in recent years there has been a great demand for a tent that can be assembled in a very simple manner and in a short time.

[Problems to be solved by the invention] The present invention was devised to eliminate the above-mentioned drawbacks of the conventional technology and to satisfy the demands of recent years. To provide a large folding tent which can be carried out in an extremely short time and with simple work and whose weight is reduced compared to conventional ones.

[Means for Solving the Problems] The folding tent of the present invention includes a first pipe that stands approximately perpendicular to the ground, and a second pipe that is telescopically fitted coaxially to the first pipe. a tube, a plurality of bones that are pivotally supported on the outer wall of the first tube so as to be swingable up and down, and extend radially from the first tube; supported and extending radially from the second canal, each end of each of which has the same number of cores as the pivotally supported cores, and extending from the top of the second canal to the end of each of the core bones; a tent cloth provided therein, a threaded rod extending along the axis within the first tube, the threaded rod being supported so as to be immovable in the axial direction and rotatable about the axis; The tube is provided with a female thread, and the female thread is screwed into the threaded rod, and the first tube is provided with a drive means that engages with the threaded rod and rotates the threaded rod.

[Operation] With the above configuration, by driving the driving means, the second pipe is moved in the axial direction due to the threaded relationship between the threaded rod and the female threaded portion of the second pipe, and the second pipe is moved in the axial direction. By moving the second tube so as to contract downward relative to the first tube, the coronal bone and the main bone are pivoted to each other, so that the main bone opens radially. This opens the folding tent and at the same time stretches the tent cloth under tension. When the second tube is spirally moved in the direction of extension with respect to the first tube, the master rib is retracted inwardly by the coronal bone, thereby closing the collapsible tent.

[Example] The present invention will be described below based on an example shown in the drawings.

In FIG. 1, the reference numeral 10 indicates a first pipe, and this first pipe is erected on the ground. In order to erect this first tube 10 on the ground, in this embodiment, a plurality of L-shaped leg tubes 12 are inserted into the lower end opening of the first tube.
The second leg portions 14 horizontally extend radially from the first tube 10, so that the first tube 10 can be reliably installed on the ground. Note that reference numeral 16 indicates a tube for bundling and fixing the portions of the leg tubes 12 inserted into the first tube 10.

At the upper end opening of this first tube, the first tube 10
A second tube 18 having a smaller diameter is slidably inserted therein. A plurality of brackets 22 are attached to the upper end of the second tube 18 via upper lathe tubes 20 fixed to its outer wall. This bracket 22
A plurality of ribs 24 are provided on the shaft 24 via pins 26 so as to be able to swing up and down. A coil spring 30 is attached to the upper end opening of the second pipe 18 via a branch pipe 28, and a coil spring 32 is interposed between the coil spring 30 and the upper end of the second pipe 18. This formation 30 is biased upward. A tent cloth 34 is stretched over the ends of the main ribs 24 that extend radially with the ridge 30 as the apex, and the tent cloth 34 is stretched under tension due to the biasing force of the coil spring 32.

In addition, at the upper part of the first pipe 10, there is a bottom wheel pipe 36.
are fixed, and the lower raceway tube 36 is provided with the same number of brackets 38 as the brackets 22.
A coronal bone 42 is pivotally supported on each bracket 38 via a pin 40 so as to be able to swing up and down, and the end of each columbar bone 42 is connected via a pin 44 to a substantially central portion of each corresponding main bone 24. is supported by. Reference numeral 46 is a bracket fixed to the main rib 24.

As shown in detail in FIG. 2, the threaded rod 5 extends along the axial direction from the bottom of the first tube 10 to the portion where the second tube 18 is inserted into the first tube 10.
0 is extended. A partition wall 52 is fixed at the lower part of the first pipe 10, and the lower end of the threaded rod 50 is fixed immovably in the axial direction by the partition wall 52, and also fixed in the axial direction. is rotatably supported. This threaded rod 50 extends further down the partition wall 52, where a bevel gear 54 is integrally attached. Another bevel gear 56 that meshes with this bevel gear 54 is rotatably supported on the wall surface of the first tube 10, and a rotating shaft 58 of this other bevel gear 56 passes through the first tube 10 in the diametrical direction. . A snap ring 60 is provided at one end of the rotating shaft 58 to prevent it from coming off, and a lever 62 extending perpendicularly to the shaft 58 is connected to the other penetrating protrusion. code 64
is a gripping part of this lever 62, and this gripping part 6
When the worker rotates 4, the bevel gear 5
6. The threaded rod 50 is adapted to rotate around its axis via the bevel gear 54. Reference numeral 66 is a nut integrally fixed to the threaded rod 50 to prevent the threaded rod 50 from falling off.

Further, a bottom plate 66 is fixed to the lower end of the second pipe 18 inserted into the first pipe 10.
A nut 68 forming an internally threaded portion is integrally fixed to the center of the nut 6 . This nut 68 is screwed onto the threaded rod 50, and therefore, the threaded rod 50
rotates while being prevented from moving in the axial direction, the threaded relationship causes the second tube 18 to rotate along the axial direction.
It functions to move spirally. Reference numeral 70 denotes a sliding member provided at the lowest end of the second tube 18, and this sliding member 70 slides along the inner wall of the first tube 10 and moves in the axial direction of the second tube 18. It is designed to facilitate the movement of people.

Next, the operation of the above configuration will be explained.

FIG. 3 shows this folding tent in a closed state. When the operator rotates the grip portion 64 of the lever 62 in the state shown in FIG. 3, the threaded rod 50 rotates around its axis. In response to this rotation, the nut 68 integrally provided on the second tube 18 is screwed onto the threaded rod 50, so that the second tube 18 is rotated in the direction and amount of rotation of the threaded rod 50. Accordingly, it spirally moves in the axial direction. When the second tube 18 spirally moves downward from the state shown in FIG.
Both bones 24, 42 are moved to open, and eventually become fully open as shown in FIG. Here, at the top of the tent cloth 34, the pitcher 30 is always urged upward by the coil spring 32, so that the tent cloth 34 is always in a tense state.

In addition, when using this foldable tent as a collective tent, at least
It is best to set the length of 4 to about 2.5m. Even if such a large folding tent is constructed, its strength is limited because, for example, the first pipe and the second pipe are connected to each other in a telescoping type telescopic state, and opening and closing is also possible by using the threaded rod 50 with the lever 62. Since this is done using spiral movement due to the rotation of the machine, there are no problems with its strength or the force required for operation.

FIG. 4 shows an example in which an extremely large collective tent is constructed by connecting a plurality of foldable tents having the above structure to each other by using a tent cloth 34 which is approximately rectangular when viewed from above. It shows. Even in this case, each folding tent can be opened and closed simply by rotating the grip 64 or lever 62, which is the driving means, so it can be constructed with extremely simple operations. can.

[Effects] As explained above, according to the present invention, there is no strength problem even when used as a large tent, such as a group tent, and the opening and closing operations can be performed extremely easily and in a short time with a small force. It also meets the requirements of a collective tent, which has been highly desired in the past, such as being easy to store and transport.
