Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column for a tent.

[0002]

2. Description of the Related Art When a tent is stretched outdoors, it is necessary to take measures when the tent is blown by the wind. Conventionally, the tip of a rope fastened to the tent is tied to a peg called a peg, I was driving pegs into the ground.

[0003]

[Problems to be solved by the device] However, recently
The ground is solidified with asphalt or concrete
Because it is often impossible to drive pegs
In addition, there was a problem that the installation of the tent became unstable.
It is

[0004]

[Means for Solving the Problems] The present invention is flexible such as rubber.
Of the suction plate 1 in the shape of an inverted dish made of a material that has elasticity
Cylinder 2 is mounted upright in the center of the upper surface and is integrated by suction.
Ventilation hole with valve 5 on the bottom surface concave part 3 and cylinder internal space 4
And the lower part of the main body 7 of the tent
Is slidably fitted in the cylinder 2, and the column main body 7
At the lower end of the cylinder, insert it into the cylinder 2 and support it by wind pressure.
When the pillar body 7 is lifted up, the pillar body 7
By sliding the inside of the da
Intake air into the cylinder inner space 4 through the ventilation hole 6
A piston portion 8 for reducing the pressure inside the suction plate inner surface concave portion 3 is provided.
By providing a tent strut characterized by
It is intended to solve such a problem .

[0005]

Embodiments will be described below in detail with reference to the drawings. First, FIG. 1 shows a state in which a tent is installed, and the columns are firmly and closely fixed by a suction plate 1. Next, FIG. 2 shows the lower end of the column, which is a main part, and is made of a flexible and elastic material such as rubber and has an inverted dish shape.
Cylinder 2 to the upper surface central portion attached integrally in a state of standing, the vent holes 6 communicating with the cylinder inner space 4 and the suction cup bottom surface recess 3 on the bottom surface of the cylinder 2 is bored, this passage A valve 5 is attached to the opening of the pore 6 to the cylinder inner space 4, while a leather packing 10 is screwed to the outer peripheral surface of the lower end flange portion 9 of the pipe-shaped strut main body 7 so that the piston portion 8 is formed. This piston portion 8 is vertically slidably inserted into the cylinder 2, and a coil spring 11 is interposed between the lower surface of the piston portion 8 and the bottom surface of the cylinder 2 so that A stopper / cap 12 is fitted in the upper end opening, and the cylinder 2
Another vent hole 13 is formed on the lower side wall of the suction cup 1 for communicating the outside of the suction cup 1 with the cylinder inner space 4, and a valve 14 is attached to the opening of the ventilation hole 13 to the outside of the suction cup 1. It was done. Further, FIG. 3 shows the lower end portion of the column similarly to the other embodiments, and has a configuration in which the coil spring 11, the vent hole 13, and the valve 14 are removed from the configuration of the above embodiment.

[0006]

[Operation and effect of the device] The weight of the tent under normal conditions
Therefore, the lower end piston portion 8 of the strut body 7 is a coil spring.
Located in the lower end of the cylinder 2 with the lug 11 compressed
I have. When the tent is fanned by the wind, the pillar body 7 floats up.
At this time, the piston part 8 moves upward in the cylinder 2.
The valve 5 opens by sliding in the direction of
Is sucked into the cylinder internal space 4 through the ventilation hole 6,
Since the pressure inside the suction cup inner surface recess 3 is reduced, the suction cup 1 is closely attached.
The strength of the stanchion becomes stronger, and the fixed state of the stanchions becomes more stable and the wind pressure is improved.
You can endure it. Depending on the weight of the tent when the wind stops
The pillar main body 7 and the piston portion 8 descend and move as described above.
It will return to the normal state . In addition, when the piston part 8 descends
The air in the cylinder inner space 4 passes through the ventilation holes 13
Exhausted to the department. Since the present invention is as described above,
When the wind is fanned by the wind, the
The suction cup exerts a stronger suction function to lift up the column.
The present invention can reliably prevent
This will solve the above problems satisfactorily
It is effective .

Claims (1)

(57) [Scope of utility model registration request] 1. A flexible and elastic material such as rubber
Place the cylinder 2 directly on the center of the upper surface of the reverse dish-shaped suction plate 1
Mounted vertically in one piece, inside the suction cup bottom recess 3 and cylinder
The space 4 is communicated with the ventilation hole 6 with the valve 5 and
Sliding the lower part of the main body 7 of the tent into this cylinder 2.
It can be freely inserted and the inside of the cylinder 2 can be
When the column main body 7 floats up due to wind pressure etc.
Slide up in the cylinder together with the strut body 7
The air in the concave portion 3 on the inner surface of the suction plate is thus evacuated through the ventilation hole 6.
It sucks into the interior space 4 of the binder and reduces the inside of the concave part 3 of the suction cup.
A column for a tent, which is provided with a piston portion 8 for pressing.
