Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tarp that is used as camping equipment that is easy to set up.

(Conventional Technique v#) Among camping equipment carried on drives etc., a tarp is easier to set up than a tent, as shown in Figure 7. Pillar (b)
It consists of a waterproof sheet (a) when installing.
Spread out the waterproof sheet (a), and with the tip of the support (b) supported on the support part provided on the waterproof sheet (a), attach the multiple support (
After erecting the support pole (b), a rope (c) is stretched between the pole (b) and a stake that has been set in the ground in advance, and the waterproof sheet (a) is then stretched. Therefore, in the erected state, the waterproof sheet (a) is supported by the pillars (b) at various sides and in the center, resembling a flat roof, which not only protects from the rain but also serves as a sunshade.

(Problem to be Solved by the Invention) However, in this type of tarp, since the waterproof sheet (a) is stretched flat, when a strong wind blows, the waterproof sheet (a) is agitated by the second wind. ) could come off from the support (b), or in severe cases could lead to collapse. Also,
Since a large number of posts (b) are used and they can also be erected in the center of the tarp, these posts (b) get in the way, narrowing the space and impairing convenience.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a tarp that has excellent resistance to wind and rain, is convenient, and has a small number of parts and is easy to assemble.

(Means for Solving the Problems) In order to achieve the above object, the tarp according to the present invention has an odd-numbered angular shape of approximately 3 or more in plan view, and the bulge gradually increases from each vertex toward the center, and each side A waterproof sheet that forms an obtuse angle inward when the center side is expanded, and a cylindrical shape that is formed between each vertex of the waterproof sheet and the opposite side, the side side of which is closed but the vertex side is open. and a strut insertion portion, which is inserted through each of the openings of the strut insertion portion, each one end of which abuts each of the closed portions, and each other end of which protrudes from the opening to serve as a leg portion;
The waterproof sheet is curved due to elastic deformation to extend the waterproof sheet in a dome shape.

(Function) With the above configuration, when setting up the structure, the waterproof sheet is spread out and one end of the support is inserted through the opening of each support insertion portion. At this time, the struts are inserted along the waterproof sheet whose bulge gradually increases from each vertex toward the center, so that it is curved due to elastic deformation and applies tension to the waterproof sheet. Then, a waterproof sheet is stretched in a dome shape at a position where one end of the pillar abuts the closed portion of each pillar insertion portion.

At this time, since the other end of each pillar projects from the opening and serves as a leg, the tarp can be set up and put into use by grounding the leg. In this state, the center side of each side cut into a substantially concave shape becomes the entrance of the tarp.

Furthermore, one end of the struts is not grounded and the other end is used as a leg, and there is no strut in the center of the tarp, so the number of struts used is reduced and a large space can be taken up.

(Example) Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a plan view of a tarp according to the present invention.

This tarp (1) has struts (
10), and the waterproof sheet (2) is stretched in a dome shape.

The waterproof sheet (2) is formed into a substantially triangular shape in plan view by sewing together six pieces of hagi (3). This clover (3) is
As shown in Figure 2, a synthetic fiber such as nylon taffeta coated with urethane has a short side (3a) and one long side (3b) that are curved, and the other long side (3c) is curved. Obtain it by cutting it into a straight line and a triangular shape on the long side. First, the short sides (3a) of the two hagi (3), (3) are sewn together, and then three of the pair of hagi (3), (3) are prepared and the long sides of each hagi (3), (3) are sewn together. By suturing one side (3b), the bulge gradually increases from each vertex (2a) toward the center (C), and the center of each side (2b) forms an obtuse angle (2). form.

The pillar insertion parts (4), (5), and (6) are cylindrical and made of the same material as the waterproof sheet (2), and are opposite to each vertex 2a) of the waterproof sheet (2). side (2b
) is provided between the center of the First pillar insertion part (4)
are sewn along the sewn portion on the back side of the waterproof sheet (2), making it easier to stretch the waterproof sheet (2) using struts (10), which will be described later.

In addition, the second and third pillar insertion parts C5), (6)
are sewn along the seam portions on the upper side of the waterproof sheet (2) in the same way as above, but each strut insertion portion (5)
, (6) have been removed to facilitate the insertion of the strut (10) and to prevent the overlapping portion from becoming too high. Then, the first to third pillar insertion portions (
4), (5), (6), the opening is sutured only on each side (2b) side to create the closed part (4b), (5b), (
6b), and each vertex (2a) side has an opening (4a),
(5a) and (6a), the struts (lO) are inserted through these openings.

Further, a band-shaped fastening piece (7) having a ring (7a) and a hole (7b) is attached to each vertex (2a) side of the waterproof sheet (2), and the ring (7a) The support (10) is inserted through the hole (7b), and the string (7c) is inserted into the hole (7b).
is threaded through it, and this string (7c) is to be tied to the peg (11). In addition, the waterproof sheet (2
) on the upper surface side of the first to third pillar insertion parts (4
), (5), and (6), a ring-shaped stopper (8) is attached to the middle part, and this stopper (8)
A rope for fixing the installed tarp (1) can be tied to it. (9) is a hooking member for hooking a lamp or the like attached to the back side of the waterproof sheet (2).

The support column (10) is a duralumin pipe, and is made elastic and bendable by connecting a plurality of short pipes with a tensioning rope.

Three pillars (10) are prepared, but when assembled, they are slightly longer than the pillar insertion parts (4), (5), and (6), and the pillars (10) are inserted into these pillar insertion parts. The other protruding end portion is a leg portion (10b). Further, as shown in FIG. 6, a belt (12) is stretched over this leg (1, Ob). This belt (
12) is a combination of three pieces, with a length adjustment part (
12a) is provided, and an insertion hole is formed at the end, and the leg part (10b) is inserted through this insertion hole to adjust the adjustment part (12a).
By adjusting 12a), the height of the tarp (1) can be freely changed.

To explain how to set up the tarp (1) configured as above, first, select an appropriate location, spread out the waterproof sheet (2), and place pegs in the ground using each vertex (2a) as a guide. (11) is poured.

Next, attach one end (10a) of the assembled support column (10) to the first
Insert through the opening (4a) of the column insertion part (4). At this time, the pillar (lO) is moved from the apex (2a) side to the central part (C
) A waterproof sheet that gradually expands toward ) (2)
As it is penetrated along the column, the support column (10) bends due to elastic deformation, but the waterproof sheet (2) gradually expands. And the closing part (4b) of the first pillar insertion part (4)
At the position where one end (10a) of the strut (10) abuts, the other end (j
ob), tension is applied to the waterproof sheet (2). Next, the second and third pillar insertion parts (5)
, from the openings (5a) and (6a) of (6)
10) one end (10a) is inserted into the closing part (sb),
(6b) and the ring (7) of the fastening piece (7).
When the other end (10b) of the support column (10) is inserted through a), the waterproof sheet (2) is stretched in a dome shape as shown in Fig. 6. (Enlarge to the size shown). At this time, the other end (10b
) project from the openings (4a), (5a), and (6a) and serve as legs, so the tarp can be placed on the ground by grounding these legs (10b).

Thereafter, by tying the strings (7c) of the fastening pieces (7) to the pegs (11), the tarp (1) can be firmly set up. In this state, each side (2b) of the waterproof sheet (2)
is almost concave toward the center.

This can be used as an entrance/exit (1a). In addition, there is no support (10) in the center of the tarp (1), and the other end of each support (10) is used as a leg (10b), and one end (10a)
Since it is not grounded, a large space can be taken up and the number of columns (10) used can be reduced.

(Effects of the Invention) As explained above, in the tarp according to the present invention, each side of the waterproof sheet is formed into a substantially concave shape.

A cylindrical post insertion part is provided between each vertex and the opposite side, and the waterproof sheet is stretched in a dome shape using three posts that are inserted through this post insertion part, making it easy to set up. It is extremely easy to use, has a simple structure, and has the advantage of being able to be stored compactly. Furthermore, when the waterproof sheet is stretched, one end of each of the three pillars is not grounded, and each other end is used as a leg, so the number of pillars can be reduced by half. In addition, since there is no support in the center of the dome-shaped tarp, you can take up more space and reduce air resistance.
Another advantage is that the steel ring does not easily break when whipped by strong winds. Furthermore, since the center side of each side is cut into a substantially concave shape, this side can be used as an entrance and exit, and has excellent effects such as good ventilation and increased stability.
