Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a tent that can be easily and quickly assembled and folded.

[Conventional technology]

The conventional tent has tent 3 as shown in Figure 6.
The upper ends of the struts 32 are stuck into both ends of the ridgeline of the strut 32, one end of the rope 33 is secured to the upper end of the struts 32, and the other end of the rope 33 is secured to the pegs 34 and stretched.

[Problem that the invention attempts to solve]

Because the pillars were located in the center of the doorway, which was located in the triangular wall at one end of the awning, there was a problem that the doorway became narrow.

In addition, since a person had to enter the tent and pierce the top of the tent, it was time consuming and the tent could not be pitched by one person.

Furthermore, when the pillars are used, they are added to make them longer, and when they are not used, they are disassembled and made shorter, which is a time-consuming problem.

There was also the problem that if the pegs came loose, it would fall over.

[Means for solving problems]

In order to solve the above problems, this invention includes an upper wheel having a through hole in the center, an upper end rotatably attached to the upper wheel, and arranged radially.
A large number of spines that can be bent upward and outward from the straight extended state, both ends of which are rotatably attached to the lower wheel and above the bent joint of the spine, are attached to the lower side of the upper wheel. A connecting bone whose supporting bones at both ends become lower when the lower wheel is stopped, a rope that is inserted through the through hole and whose lower end is locked to the lower wheel, and a rope that protrudes from the center of the upper surface of the lower wheel so as to pass through the through hole. A protruding shaft, a threaded part provided on the outer circumference of the protruding shaft, a cap connected to the upper end of the rope and screwed into the threaded part, the center of the upper surface on the upper wheel, and the lower edge on the lower end of the support bone. It consists of an awning with an attached entrance and exit, and a bottom sheet whose periphery is connected to the entire lower edge of the awning.

[Effect]

Grasp the cap and pull the rope upwards to pull up the lower wheel.

As a result, the lower wheel side of the connecting bone is raised, and the awning and bottom sheet are automatically expanded while pushing open the supporting bones.

At this time, the upper end of the upper wheel comes into contact with the lower end of the upper wheel and stops, and the protruding shaft passes through the through hole.

Then, a cap is screwed onto the projecting upper end side of the projecting shaft to prevent the lower wheel from descending and maintain the assembled state of the tent.

Furthermore, in order to fold the tent, first remove the cap, then press down on the protruding shaft with the pair, the lower wheel descends and the lower wheel side of the connecting bones descends, so the supporting bones are pulled together.

In addition, the length of the spine is shortened by inverting the lower side upward from the mid-fold joint, and then folded to make it less bulky.

〔Example〕

In the figure, reference numeral 1 denotes an upper wheel having a through hole 2 in the center through which the upper and lower surfaces penetrate, and this upper wheel 1 has a radial arrangement having a bent joint 3 whose lower end flips upward and outward from the straight extended state. The upper end of the support bone 4 is rotatably attached.

Reference numeral 5 denotes a lower wheel, and both ends of a connecting bone 6 are connected to this lower wheel 5 and above the joint portion 3 of the support bone 4 so as to be freely rotatable.

When the upper surface of the connecting bone 6 is brought into contact with the lower surface of the upper wheel 1 and the lower wheel 5 is stopped, the supporting bone 4
The connecting point on the lower wheel 5 side is inclined to be slightly higher than the connecting point on the support bone 4 side so as to maintain the pushed-open state.

A rope 7 is inserted through the through hole 2 and has its lower end fixed to the lower wheel 5.

Reference numeral 8 designates a protruding shaft that projects from the upper surface of the lower wheel 5 so as to penetrate into the through hole 2 when the lower wheel 5 is stopped by contacting the upper wheel 1.

Note that by making the upper end surface of the protruding shaft 8 semispherical as shown in the figure, the protruding shaft 8 can be smoothly inserted into the through hole 2.

Reference numeral 9 denotes a threaded portion provided on the outer circumferential surface of the protruding shaft 8 that protrudes from the through hole 2 .

Further, a cap 10 screwed into the threaded portion 9 is connected to the upper end of the rope 7.

The above cap 10 is attached to a nut plate 1 as shown in the figure.
After inserting the rope 7 into the central through hole 12 of the nut plate 1, a knot 13 is provided at the end of the rope 7, and the nut plate 1 is attached.
1 is prevented from coming off, and a nut plate 11 is screwed into the internal threaded portion 10' of the cap 10 to connect it to the rope 7, thereby preventing rainwater from entering.

Note that a weight 1 is attached to the lower end of the rope 7 as shown in the figure.
4, the rope 7 can be automatically lowered when the lower wheel 5 is pulled up and the tension on the rope 7 is released.

Reference numeral 15 is an awning in which the center of the upper surface is attached to the upper potter's wheel 1, the middle part is attached to the support bone 4, and the lower edge is attached to the lower end of the support bone 4.The circumferential edge of the bottom sheet 16 is sewn around the entire lower edge of the awning 15. etc. are connected.

As shown in the figure, the annular protrusion 17 on the upper surface of the upper wheel 1 and the annular step 18 on the lower surface of the cap 10 are fitted together, and the upper wheel 1 and the cap 10
Since the awning 15 is sandwiched between the two, it is possible to prevent rainwater and wind from entering.

Further, as shown in the figure, a through hole 1 for passing a rope 7 through which the center of the upper end surface of the protruding shaft 8 and the lower surface of the lower wheel 5 communicate with each other.
9 is provided, and a large diameter recessed portion 20 is provided on the lower surface of the lower potter's wheel 5.
A recessed hole 21 is formed upwardly from the center of the bottom surface of the recessed part 20.
are provided respectively, and a rubber cylindrical body 2 is provided in the recessed part 20.
2, fit the tube shaft 23 into the recessed hole 21,
The flange 24 provided at the lower end of the tube shaft 23 is fitted into the cylindrical body 22 so that the lower surface of the flange 24 is positioned above the lower edge of the cylindrical body 22. Even if there is a collision, the bottom sheet 16 can be prevented from being damaged by being cushioned by the cylindrical body 22.

In the figure, reference numeral 25 denotes an auxiliary sheet for fitting the central through hole 26 into the cap 10, and ropes 27 extending from the squares of this auxiliary sheet 25 are fixed to pegs. Reference numeral 28 denotes an entrance/exit provided in the awning 15 so as to be opened/closed by disengaging and interlocking the interlocking teeth by sliding a slider.

〔effect〕

As described above, according to the tent according to this invention, by pulling the rope and pulling up the lower wheel below the upper wheel, each vertex is pushed open via the connecting bones that rotate in the direction of collapse. The awning and bottom sheet can be automatically expanded.

This eliminates the need to use poles or attach ropes to pegs, allowing one person to easily and quickly pitch the tent.

In addition, since the cap is screwed onto the protruding shaft that penetrates the through hole and protrudes upward to prevent the lower wheel from falling, it is possible to prevent the tent from collapsing as the protruding shaft is pushed down. At the same time, the cap prevents rainwater and wind from entering.

Furthermore, since a bending joint is provided in the middle of the spine, the length can be shortened and folded.

In addition, when the lower wheel is stopped at the lower side of the upper wheel, the connecting point on the lower wheel side is slightly higher than the connecting point on the supporting bone side of the connecting bones, so the condition of pushing the supporting bones apart is prevented. can be maintained.

Therefore, even if the tension on the rope is released, the protruding shaft can be prevented from coming out of the through hole.
