Abstract

To provide a single-flow tent simplifying an attachment work of a metal frame and an awning during setting of the single-flow tent, reducing a burden of operators and users and strong against wind and rain.SOLUTION: In a single-flow tent, internal pressure due to blow-in of wind is released while preventing rainwater intrusion by doubling a tent fabric of an awning four sides hanging part at four corners, and the single-flow tent is attached firmly to a metal frame group by a tension tool allowing a wire in a fabric band penetrating into a ceiling part of the awning in an X-shape to be opened and closed in a single operation.SELECTED DRAWING: Figure 1

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single-flow tent capable of reducing the wind pressure on the tent and saving the labor of installing the tent.

Conventional tents of various types are fixed with stakes or weights so that they are not blown away by wind pressure. A method of tightening multiple points on the inner beam is generally adopted.

The wind that blows in from the outside accumulates in the canopy, and in strong winds, the parts may be damaged, and the entire tent may fly up, causing damage to surrounding equipment and injury. Also, since there are many connection points, it is difficult to remove the awning suddenly.

On the other hand, in order to withstand wind and rain, the frame must be strong and heavy, and the awning must be attached at many points, requiring a great deal of man-hours to install and remove it. sometimes even require

In view of the above-mentioned problems, it is an object of the present invention to provide a single-flow tent that simplifies the construction work, reduces the burden on workers, withstands wind and rain, and prevents rainwater from accumulating on the ceiling.

In order to solve the above-mentioned problems, the tent according to claim 1 consists of a metal frame group composed of beams and pillars, braces that connect and reinforce them, and flints, and an awning. and a line tensioning device for tensioning the wire and connecting the awning and the frame group.

3. The line inside the cloth band of the awning for tent according to claim 2 extends out from each end of the cloth band, puts a ring on both ends, hooks one end to the hook provided on the fire strike, and attaches a tensioning tool to the other end. It is characterized in that the awning is connected to the frame simply and firmly by connecting it and pulling it in a cross shape between the fire strikes in the diagonal position.

In addition, the hanging parts of the four sides of the awning described in claim 2 do not cut off the four corners of the original fabric of the awning, but simply make cuts and double the fabric at the corners to prevent rainwater from entering and to ventilate. Characterized by

The above-mentioned ventilation structure and the one-touch opening and closing mechanism of the above-mentioned wire tensioning device can prevent danger in strong winds, save labor in setting up and dismantling the tent, and reduce the cost of fixing weights and piling.

The wind that blows into the tent is discharged from the four sides of the banner, reducing the pressure load on the frame group and reducing the weight of the frame.
In particular, single-flow tents have a wider hanging curtain area than gabled (generally called house) and square hipped roof tents, which are widely distributed, and the ventilation effect is overwhelmingly large.

(A) is a perspective view of the tent according to the present embodiment in a completed assembled state, (B) is a front view from the height direction of the frame, and (C) is a plan view of the frame seen from the upper surface before raising the pillars. , (D) is a schematic diagram of a wire tensioning mechanism, and (E) is a plan view showing a method of cutting the awning 1 and closing the four corners.

An embodiment of the present invention will be described below with reference to FIG. First, as a frame assembly procedure, lay the pillars 3 radially on the ground as shown in (C), fold them upward at the center folding metal fittings 5, and attach them to the upper beam supports 3-1 at both ends of the beam 2-1 by about 90°. °The short pipes welded downward are inserted, but the beams on the front and back are long, and for convenience of transportation and handling, the three pipes on the left and right and in the middle are connected with two folding metal fittings 5. There are, and these are used by extending them in a straight line.
By the way, the folding metal fitting 5 has a structure in which one side of the folding metal fitting 5 can be folded around the pin shaft inside the U-shaped iron plate cover.

As seen in FIG. 1(C), the left and right beams 2-2 are similarly extended at the center and inserted into the upper ends of the front and rear pillars.

Next, the two-dot chain line in (C) is an imaginary line when the awning is put on, and the hollow cloth belt shown in (D) 8 is welded diagonally to the back of the awning, and the wire 8 is passed through it. be. After hooking the ring 9 on one end of the wire to the hook 6-1 welded to the lower surface of the two stilt beams 6 on the tall side among the 4 stilt beams 6 provided at the four corners of the frame, raise all the pillars, and A bracket 4 is hung between the pillar 3 and each beam 2 to complete the frame group.

FIG. (D) is a schematic diagram of a method of stretching the cloth band 7, the wire 8, and the rings 9 at both ends in an X-shape between the four corners of the awning with a tensioning tool 10. FIG. As described above, after raising the entire tent in the state shown in FIG. 1 is hooked on the left and right flint beams 6 on the lower side and the lid 10-3 is closed, the wire is tightened, and the frame group and the tent are integrated without looseness. The J-shaped straight portion of the hook 10-1 is a male screw and is fitted with a nut under the main body 10 of the tensioning device so that the degree of tension can be adjusted.

FIG. (E) shows the manufacturing method of the awning 1 . First, cut it into the shape shown in the figure, make a cut along the line 1-2, and fold it at the two-dot chain line to form a banner 1-1 on the four sides, with two overlapping corners. Next, the male hook 1-4 and the female hook 1-5 are put together inside. The four corners are the same, the cloth band 7 is welded to the back of the ceiling surface, and the wire 8 is passed through to complete the awning.

In the tent according to the present invention, the wind pressure treatment has already been completed by fixing the four corners as described above. In the interior of the ceiling, it is also possible to attach auxiliary connectors for connecting the periphery of the ceiling and the frame beams.
