Description

The present invention relates to a tarp that is installed in a camp or the like to prevent sunlight, wind, rain, etc.

In outdoor life such as camping, tarps are used to prevent sunlight, rain, wind, etc. There is a non-self-supporting type of tarp that can be stored compactly and is lightweight, but when it stands, it hits a peg on the ground and pulls it with a rope to support the support and prevent it from falling over. However, it is difficult and time-consuming to set up by one person, and it cannot be set up unless the pegs are struck on the ground. In addition, it is necessary to secure a pegging point, which is a problem that cannot be dealt with in a narrow section.
In response to such problems, various self-supporting tarps have been proposed that can stand in a smaller space than the non-self-supporting type without hitting a peg (for example, Patent Documents 1 and 2).

However, if the tarp is self-supporting, it becomes heavy as in Patent Documents 1 and 2. For example, in Patent Document 1, the skeleton structure is fixed to the columns 2a to 2d by the side frame 3 of another member, the upper part is heavy, the skeleton itself including the columns must be strong, and the capacity is large even when folded during transportation. Moreover, there was a drawback that it became heavy.
Further, there is a problem that the center of the awning (waterproof sheet) hangs down, and in order to solve this problem, for example, as described in claim 3 of Patent Document 3, "... intervening between the upholstery member and the back surface of the waterproof sheet". However, a short strut that pushes up the central portion of the waterproof sheet upward was required.

The present invention solves the above-mentioned problems, and is a self-supporting tarp, which is not bulky in terms of capacity, is lightweight and easy to carry, and also has a problem that the center of the awning hangs down without a separate member. The purpose is to provide a tarp that can be eliminated.

In order to achieve the above object, the gist of the first invention is that an elastic rod-shaped beam member that erects a strut on the ground at each corner of a polygon in a plan view and connects to the upper end of each strut via a joint is the plane. The turret (1) formed three-dimensionally by engaging the intersections of the beam members with the hub joint at the center of the visual polygon, and the joints or the upper portions of the columns are integrated with each other. The locked body (6) is formed into a ring shape by a string material having a length shorter than the total length, which is hooked on each locking body integrated with the turret body and connected in a ring shape along the plan view polygon. Or, when a portion in which one end side of a plurality of cords is bundled is arranged in the center, the length from the center to the other end of each cord is set from the center to each locking body. A string-like body (7) made of a first string-like body (7A) shorter than the distance and a cloth-like awning (8) covering the upper surface of the turret are provided, and the first string-like body (7A) is provided. ) Is hooked on each locking body to form an annular shape, or the other end portion of each string material in which one end side of the first string-shaped body (7A) is bundled is locked to each locking body. When each of the string members is stretched in a radial pattern, the string member elastically deforms the beam member in an arc shape and pulls the column member so as to make the plan-view polygonal shape formed by the column member one size smaller. It is in the tarp that is characterized by that. The second invention , the tarp, is the first invention in which the string-like body (7) is attached to each of the locking bodies on one end side in place of the first string-shaped body (7A), and the locking tool is provided. These cords were separated so that the length of each cord to the other end of the attachment was shorter than the length from the locking tool to the center or the length to the adjacent locking body. It is composed of a second string-like body (7B), and each of the locking tools of the second string-like body (7B) is locked at one place in the center or is locked to an adjacent locking body. Therefore, the string member elastically deforms the beam member in an arc shape, and pulls the support column so as to make the plan view polygonal shape formed by the support column one size smaller. The third invention , the tarp, is the second invention, in which the string-like body (7) replaces the first string-like body (7A) with one of the locking bodies on the diagonal line of the plan view polygon. These cords are separated from each other by attaching one end side and shortening the length of each cord to the other end to which the locking tool is attached, which is shorter than the length to the other locking body on the diagonal line. It is composed of a configured third string-like body (7C), and each of the locking tools of the third string-like body (7C) is locked to the other locking body, so that the string member is the beam member. Is elastically deformed in an arc shape to pull the support column so as to make the plan view polygon formed by the support column one size smaller. The fourth invention , the tarp, is the first to third inventions , characterized in that the polygon in a plan view is made rectangular and the center thereof is an intersecting portion where the diagonal lines of the rectangle intersect. The fifth invention , the tarp, is the first or second invention , characterized in that the plane-viewing polygon is a plane-viewing regular polygon and is an equilateral triangle, a square, a regular pentagon, or a regular hexagon. The sixth invention , the tarp, is the first to fifth inventions , wherein the central axis of the support column to which the upper end portion is integrated or attached to the joint and the central axis of the beam member to which one end side is connected to the joint are formed. It is characterized in that it intersects in an inverted L shape and the internal angles of the support column and the beam member are set to be obtuse.

The tarp of the present invention is a self-supporting type that can maintain stability, is lightweight and can be made compact without taking up space, can be stored and carried, and can solve the problem of the center of the awning hanging down without a separate member. It works well.

An explanatory view in which each locking tool is hooked and locked to the four locking bodies of FIG. 4 and the beam member is elastically deformed in an arc shape. FIG. The perspective view of the joint, (b) to (d), is a perspective view of the hub joint instead of (a). In addition, each figure is shown as a simplified drawing, and components and members which are not directly related to the present invention are omitted. Further, in order to make the drawings easier to understand, FIGS. The illustration of the support column 2 with the joint 3 and the locking body 6 is omitted.

The tarp includes a turret body 1, a locking body 6, a string-like body 7, and a tent 8. The turret 1 includes a support column 2, a joint 3, a beam member 4, and a hub joint 5. The elastic rod-shaped beam member 4 that erects the column 2 on the ground GL at each corner of each vertex region of the polygon in plan view and connects to the upper end portion 21 of each column 2 via the joint 3 is a polygon in plan view. It is a skeleton structure that is three-dimensionally formed by engaging a portion that intersects at the center (here, the central portion) of the inside and where each beam member 4 intersects with a hub joint 5 that is a connecting joint. In the hub joint 5, the number of cylindrical portions of the intersecting beam members protrudes radially from the center according to the number toward the center. The turret 1 of the present embodiment has a rectangular shape in a plan view as shown in FIG. 1, and is a hexahedral space-forming frame that can function as a tarp with a feeling of liberation that can be spent comfortably.

The columns 2 of the turret 1 are poles having rigidity that can be maintained upright on the ground GL at the four corners of a rectangular shape in a plan view including a square, and four poles having a length that allows the awning 8 to be arranged at a required height are prepared. Each support 2 is one, but the divided components may be connected like a fishing rod.

The beam member 4 is an elastic rod-shaped member made of aluminum, synthetic resin, or the like. The rod shape of the rod-shaped beam member 4 in the present invention includes a pipe shape as well as a shaft shape. The beam member 4 has a shape elasticity that tends to return to its original shape even if it is made straight as shown in FIG. 2 and deformed into an arc shape by applying an external force as shown in FIG. Here, the beam member 4 has a length that bridges the upper end portions of the columns 2 that face each other diagonally in a square shape with a joint 3 via a joint 3. Specifically, as shown in FIG. 2, the central shaft 2f of the support column 2 to which the upper end portion 21 is attached to the joint 3 and the central shaft 4f of the beam member 4 to which one end 41 side is connected to the joint 3 intersect in an inverted L shape. Moreover, the internal angle θ of the support column 2 and the beam member 4 is set to be an obtuse angle. The beam member 4 has a smaller cross-sectional diameter and is lighter than the support column 2 in order to facilitate elastic deformation. One end 41 side of the beam member 4 is inserted and fixed to the beam member side tubular portion 3b of the joint 3 with the support column 2 in which the upper end portion 21 of the support column is inserted into the column side cylinder hole 30 of the joint 3. Although a separate joint 3 is attached to the support column 2, the joint 3 may be integrated with the upper end portion 21 of the support column 2. A gate-shaped frame body formed by bridging the upper end portions 21 of the columns with a pair of joints 3 with a single beam member 4 in a square shape becomes one unit, and two sets thereof are arranged. Then, as shown in FIG. 1, the two beam members 4 intersect at the center of the rectangular shape in a plan view formed by connecting the four columns 2, and the hub joint 5 is engaged with the intersecting portion to form the turret 1. ..

In the present embodiment, as shown in the drawing, the two beam members 4 intersect in a crossing shape so as to form a rectangular diagonal line, and the hub joint 5 engages with the intersecting portion. The hub joint 5 is a connecting member in which two metal cylinders are brought into contact with each other substantially orthogonally as shown in FIG. 6A, and the contact portion is welded to a joint portion 59. The central portion of the two beam members 4 penetrates the tubular hole 50 of the hub joint 5, and both ends of the beam member 4 are connected and fixed to the upper end portion 21 of the column via the joint 3. It suffices for the hub joint 5 to be able to engage and hold the intersection of the beam members 4 in the intersecting state, and the hub joint 5 as shown in FIGS. 6 (b) to 6 (d) can also be used. In FIG. 6 (b), the two shaft bodies are orthogonal to each other to form a connecting portion, and a tubular hole 50 is formed from the shaft end faces on all sides to near the center of the shaft body, but does not penetrate. In such a case, the length of the beam member 4 is about half that of the beam member 4 of FIG. 2 (a). A beam member having a length that connects one end side of two beam members 4 to a joint 3 attached to the upper end portion 21 of the opposite column, connects the other end side with the hub joint 5 in the middle, and bridges in a square shape. It becomes 4. FIG. 6 (c) shows a hub joint 5 in which the tubular body 5a of FIG. 6 (a) is replaced with a ring 5b having a ring hole 51, and FIG. 6 (d) shows the tubular body 5a of FIG. It is a hub joint 5 instead of. The intaglio piece 5c in which the side plate portions 522 are erected on both sides of the bottom plate portion 521 forms a concave groove 52 in which the lower side of the lower concave plate piece and the upper side of the upper concave plate piece open to engage the beam member 4. Match. The protruding portion 523 prevents disengagement after engagement.

However, the turret 1 only engages a plurality of beam members 4 at one location of the hub joint 5, and is prone to wobbling at that location and lacks a sense of stability as a skeleton. Therefore, in the present invention, the locking body 6 and the string-shaped body 7 are stably maintained as the turret 1 of the self-supporting tarp in addition to the essential constituent requirements.

The locking body 6 is a hook receiving portion for the string-shaped body 7 integrated with each joint 3 of the turret body 1 or each upper portion of the upright support column 2. Here, the beam member 4 connecting the locking body 6 made of the short ring body 61 as shown to the outer surface of the cylinder of the support column side tubular portion 3a related to the joint 3 with the projecting direction of the locking body 6 connected to the joint 3. It is fixed and integrated so as to coincide with the central axis 4f direction of. Each of the four locking bodies 6 is located at the same height when the support column 2 with the joint 3 is erected on the ground GL as shown in FIGS. 1 and 4, and the four locking bodies 6 from the joint 3 are used. It is arranged so as to face the center of the rectangular shape in the plan view (see FIG. 9).

In the string-like body 7, when a portion in which one end side of a plurality of string members 71 is bundled is arranged in the center, the length from the center to the other end of each string member 71 is set from the center to each engagement. It is the first string-like body 7A shorter than the distance to the stop body. As shown in FIG. 1, the turret body 1 is three-dimensionally formed, and a portion connecting one end side of a plurality of string members 71 is formed with the locking body 6 at the center of the plan view polygon formed by each of the locking bodies 6. It is a string-shaped object as shown in FIGS. 1 and 3 in which the length from the center to the other end of each string member 71 is shorter than the distance from the center to each locking body 6 when placed on the same horizontal plane. .. In the present embodiment, the columns 2 and the locking body 6 are arranged at each corner where the vertices of the plan view rectangle are located, and the center of the plan view polygon is an intersection where the diagonal lines of the plan view rectangle intersect. In FIG. 3, in which the binding portion 79 of the string-shaped body 7 is aligned with the center of the rectangular shape in a plan view (intersection of diagonal lines), the double value L2 of the length from the center to the other end side of each string member 71 faces each other. The distance between the locking bodies 6 is set to be shorter than the distance L1 on the diagonal line. Instead of this, as shown in FIG. 9 (details will be described later), a string-like body 7A formed in an annular shape by a string material 71 having a length shorter than the total length, which is hooked on each locking body 6 and connects each support column 2 in a square ring shape. There may be.
In the present embodiment, one end side of four string members 71 is tied to form a binding portion 79, and a J-shaped metal locking tool 72 as shown in FIG. 1 is attached to the other end of each string member 71. Let it be a string-shaped body 7A. Then, the beam member 4 is elastically deformed in an arc shape to make the plane view polygon formed by the support 2 of the original turret 1 one size smaller, and the locking tool 72 which is the other end of each string member 71 is turret 1 Each of the locking bodies 6 is hooked and locked, and each string member 71 is radially stretched (FIGS. 4 and 5). The beam member 4 is elastically deformed in an arc shape by hooking each locking tool 72, which is the other end portion of each string member 71, on each locking body 6 and stretching the string member 71 in a radial pattern, and each column 2 Is pulled to the center to make the plane view polygon formed by connecting the columns 2 one size smaller.

The awning 8 is a cloth-like member for a tarp that covers the upper surface of the turret 1. The curtain body 81 has a rectangular size that can cover the upper surface of the turret 1, and the awning 8 is water-repellent, and is provided with strings 82 for attaching to the turret 1 at four corners.

The turret 1, the locking body 6, the string-like body 7, and the awning 8 are aligned, and the tarp is assembled as follows, for example.
First, the upper end portions 21 of the four columns 2 are inserted and fixed into the column side cylinder holes 30 of the joint 3, respectively. Next, the two beam members 4 are inserted into the hub joint 5 and engaged with each other, and after adjusting so that they intersect at the center, both ends of the beam member 4 are placed in the beam member side cylindrical holes 31 of the joint 3. It is a turret body 1 as shown in FIG. 1, which is inserted and fixed, and the columns 2 are erected on the ground GL at each corner of the rectangular view in a plan view.
Subsequently, the awning 8 is put on the upper surface side of the turret 1, the attachment string 82 is tied to the upper end of the support column 2 or the locking body 6, and the awning 8 covers the upper surface of the turret 1.

After that, an operator enters the hexahedral space of the turret 1 and hooks and locks each locking tool 72 of the string-shaped body 7 to each locking body 6 as shown in FIG. Here, the length of the string member 71 is set to be shorter than the length required for hooking the string-shaped body 7 to each locking body 6. Therefore, the beam member 4 is elastically deformed in an arc shape, the plan-view polygon formed by connecting the columns 2 constituting the original turret 1 is made one size smaller, and the locking members 72 of the string-shaped body 7 are respectively reduced. Hook on the locking body 6. Then, as shown in FIG. 5, each string member 71 pulls each support column 2 and beam member 4 toward the string-like body 7 side and tensions them, resulting in a tensioned state. The restoring force due to the tension applied to the string-shaped body 7 and the elastic deformation of the beam member 4 in an arc shape exerts the coupling force of each of the support columns 2, the beam member 4, the locking body 6, and the string-shaped body 7. The skeleton of the turret 1 which may be raised and integrated, and which may wobble, is stably fixed, and a self-supporting desired tarp is assembled and completed. As for the elastic deformation of the beam member 4, the turret 1 is assembled so that the central portion of the beam member 4 protrudes upward as shown in the drawing.

(2) Embodiment 2
This embodiment is a tarp as shown in FIGS. 7 to 11. Similar to the first embodiment, the number of columns 2 is four. A rubber plate 23 is provided at the lower end portion 22 of the support column.

The joint 3 is a joint 3 in which the column side cylinder 3a intersects the boundary portion between the beam member side cylinder 3b and the protrusion 3c in a T shape. Further, when the beam member 4 is attached to the support column 2 with the joint 3 standing on the ground GL to assemble the turret body 1, the beam member side tubular portion 3b of the joint 3 is larger than 0 ° and from 15 ° as shown in FIG. It also has a small elevation angle α, and is a joint that ascends and inclines toward the beam member 4 side.
The locking body 6 is a hook piece 62 as shown in FIG. 11 fixed to the lower end portion of the column side tubular portion 3a. When assembled into the turret body 1, each overhanging portion 621 of the locking body 6 faces a diagonal intersection of a rectangular shape in a plan view formed by four columns 2, and a hooking portion 622 extends substantially vertically upward from the tip thereof. Further, a return portion 623 is provided at the tip thereof toward the column side tubular portion 3a.

The string-shaped body 7 of the present embodiment is formed in an annular shape by a string material 71 having a length shorter than the total length that is hooked on each locking body 6 of the three-dimensionally formed turret body 1 and connects the respective columns 2 in an annular shape. It is a string-shaped first string-shaped body 7A. As shown in FIG. 9, a ring-shaped stopper 73 is attached to one end of a long straight string 71, and a hook-shaped stopper 74 is attached to the other end. The string portion of the string member 71 is housed in the hook piece 62 and hooked on each locking body 6, and the string-shaped body 7 is formed in an annular shape as shown in FIG. The beam member 4 is elastically deformed in an arc shape, and the support column 2 is attracted so as to be one size smaller than the plan view polygon of FIG. 9 formed by the support column 2. Since the beam member side tubular portion 3b of the joint 3 assembled to the turret 1 has an elevation angle α, the beam member 4 is smoothly elastically deformed into an arc shape that projects upward at the center where the hub joint 5 is located. do. Against the restoring force of the beam member 4 due to this elastic deformation, the string member 71 is wound in a rectangular ring shape to tighten the string member 71, and when the stopper 74 is hooked on the stopper 73, the string member 71 of the string-like body 7 is hooked. Becomes a tight state. The restoring force due to the elastic deformation of the beam member 4 makes the turret body 1 with the locking body 6 and the string-shaped body 7 tense and integrally strong. If the upper surface of the turret 1 is covered with the awning 8, the turret 1 does not wobble and becomes a desired self-supporting tarp.
In the awning 8 here, the pocket forming piece 831 is sewn with sewing thread 832 at the four corners of the square curtain main body 81 to provide the pocket hole 83. As shown in FIG. 11, the protrusion 3c can be inserted into the pocket hole 83, and the awning 8 can easily cover the upper surface of the turret 1.

In this embodiment, the turret 1 of a plan view triangle (here, an equilateral triangle) as shown in FIGS. 22 and 23 is formed. The support column 2 and the locking body 6 are the same as those in the second embodiment, and the description thereof will be omitted. A support column 2 with a locking body 6 is erected at each corner of the plan view triangle, and the hub joint 5 arranged at the center (here, the center of gravity) of the plan view triangle of the turret body 1 has a tubular body 5a of FIG. 22. It is a three-way joint that faces the beam member side tubular portion 3b of the joint 3 at an angle interval of 120 ° around the center of gravity as described above.
The beam member 4 has a length such that one end 41 is connected to the joint 3 and the other end is connected to the hub joint 5. Here, as shown in FIG. 23 (a), the beam member 4 provided with the short member 4a and the long member 4b is used, and the illustrated product in FIG. 23 (b) in which the beam member 4 is assembled to the support column 2 with the joint 3 is one. Treated as a unit. When the other end side of the beam member 4 assembled to the column 2 with the joint 3 is inserted into the three-sided tubular body 5a of the hub joint 5 located at the center of gravity, the space forming turret 1 of the triangular prism is assembled. If the awning 8 and the string-like body 7 when the beam member 4 of the short lumber 4a is used and the awning 8 and the string-like body 7 when the beam member 4 of the long lumber 4b is used are aligned, the size of the tarp Can be changed as appropriate.

The string-shaped body 7 is the center of a plan-viewing triangle in which the turret body 1 is three-dimensionally formed as shown in FIG. In the first string-shaped body 7A in which the length from the center of gravity to the other end of each string member 71 is set shorter than the distance to each locking body 6 when arranged on the same horizontal plane as the locking body. be. The same locking tool 72 as in the first embodiment is attached to the other end of each string member 71. After covering the upper surface of the turret body 1 with the locking body 6 with the awning 8, the beam member 4 of the turret body 1 is elastically deformed in an arc shape to make the plan view triangle formed by the support column 2 one size smaller, and each string member 71. The tarp is completed by hooking and locking the locking tool 72, which is the other end portion of the above, to each locking body 6 integrated with the turret 1, and radially stretching each string member 71. If the string-shaped body 7 is attached to the turret body 1 with the locking body 6, a desired tarp without rattling at the hub joint 5 can be obtained.

Although not shown, the first string-shaped body 7A and the second string-shaped body 7B shown in FIGS. 9, 12, 14 and the like can be used for the string-shaped body 7. Further, in the first to fifth embodiments, the support columns 2 are erected on the above-ground GL at each corner of the plan view quadrangle and the plan view triangle to form the turret 1 in which a hexagon or a triangular column is three-dimensionally formed. A plurality of objects shown in FIG. 23 (b) in which the beam member 4 is assembled to 2 are arranged as one unit, and the hub joints shown in FIGS. 24 (c), (d), etc. corresponding to regular pentagons, regular hexagons, etc. If 5 are aligned, it is possible to form a turret 1 having a polygonal plane view such as a regular pentagon or a regular hexagon. In addition, each product of FIG. 24 is provided with each cylinder hole 50 on the same plane, (a) of FIG. 24 is an alternative product in place of the hub joint 5 shown in FIG. 6, and (b) is an alternative product of FIG. 22. It is an enlarged view of the hub joint 5.
Other configurations are the same as those of the first to fourth embodiments, and the description thereof will be omitted. The same reference numerals as those of the first to fourth embodiments indicate the same or corresponding portions.

(6) Effect The tarp configured in this way includes the locking body 6 and the string-like body 7 even if the assembled turret 1 is slightly wobbled, elastically deforms the beam member 4, and makes the support column 2 polygonal in plan view. Each of the columns 2 standing upright at each corner of the square is pulled so as to narrow down from the chain line position in FIGS. 5 and 10 toward the inside of the polygon in a plan view, and the string-shaped body 7 is attached to the locking body 6. The tension of the string-shaped body 7 propagates to the columns 2 and each beam member 4, and the wobbling of the turret body 1 is stopped. The beam member 4 is elastically deformed in an arc shape to make the polygonal polygon formed by the support column one size smaller, and the first string-like body 7A as shown in FIGS. 8 and 12 is hooked on each locking body 6 to form an annular shape. Or, as shown in FIG. 1, when the other end portion of each string member 71 related to the string-like body 7 is hooked on each locking body 6 and each string member 71 is stretched in a radial pattern, the restoring force due to elastic deformation occurs. Is born in the beam member. This restoring force acts on each component of the turret 1 with the locking body 6 and the string-like body 7 to integrate them like a rigid body. Since the wobbling of the beam members 4 intersecting around the hub joint 5 constituting the turret 1 is eliminated and the turret 1 is stably held, if the upper surface of the turret 1 is covered with the awning 8, a desired self-supporting tarp can be obtained. .. In the second string-shaped body 7B and the third string-shaped body 7C, the same action as that of the first string-shaped body 7A works, and the turret body 1 is stably held.
And, as mentioned above, assembling and setting up the tarp is easy, and even one worker can assemble it.

Further, since the support column 2 basically supports only the tent 8 which is the main body of the tarp and the thin beam member 4, it is not necessary to make it robust. The elastic beam member 4 connected to the upper end portion of the support column 2 via the joint 3 intersects at the center of the polygon in a plan view, and the portion where the beam members 4 intersect is engaged with the hub joint 5 to form a three-dimensional shape. The beam 1 is lightweight, compact, and easy to carry. It is a self-supporting tarp that is perfect as camping equipment by eliminating the drawbacks of being large in capacity and heavy as in Patent Documents 1 and 2. It's easy to take out, and when assembled it becomes a big tarp. If you use it for camping and eat or take a nap, it will be an excellent tarp that you can feel the wind directly. Furthermore, since it is lightweight, not bulky in terms of capacity, and does not take up space, it can be always loaded in a vehicle and used as a tarp for disaster prevention.

Further, in the formation of the turret 1, the axis of the support column 2 whose upper end portion is integrated or attached to the joint 3 and the axis of the beam member 4 whose one end side is connected to the joint 3 intersect in an inverted L shape. When the internal angle θ of the support column 2 and the beam member 4 is set to be an blunt angle, the string-shaped body 7 is hooked on each locking body 6 to elastically deform the beam member 4 in an arc shape to support the support column. When the plan view polygon formed by 2 is made one size smaller than the initial chain line state of FIG. 5, the support column 2 can be maintained in an upright state and the turret 1 can be smoothly reduced.
In addition, when the string-shaped body 7 is hooked on each locking body 6 and the beam member 4 is elastically deformed in an arc shape to reduce the plan-view polygon formed by the support column 2, the hub joint is formed as shown in FIG. When the beam member 4 is elastically deformed in an arc shape so that the portion 5 faces upward, the center of the awning 8 rises, and the problem of hanging at the center can be solved. It does not require a separate member such as a short strut 2 as in Patent Document 2. When the beam member 4 is attached to the support column 2 with the joint 3 standing on the ground GL and the turret 1 is assembled, when the joint 3 having an elevation angle α is adopted for the beam member side tubular portion 3b as shown in FIG. When the beam member 4 attached to the joint 3 is elastically deformed in an arc shape, the hub joint 5 is inevitably guided and guided upward, so that the tarp as shown in FIG. 5 in which the center of the awning 8 rises. Can be formed more easily. The rain that fell on the tent 8 is smoothly washed away.

Further, if the support column 2 is erected on the ground GL at each corner of the rectangular shape in a plan view and the turret body 1 is three-dimensionally formed by the joint 3, the beam member 4, and the hub joint 5, the turret body 1 has a simplified structure but is stable. And it becomes a tarp with a feeling of openness. Further, a turret 1 formed three-dimensionally by a joint 3, a beam member 4, and a hub joint 5 by erecting a support 2 on a ground GL at each corner of an equilateral triangle, a square, a regular pentagon, or a regular hexagon in a plan view. Then, a good-looking and stable tarp can be obtained.
Further, when the string-shaped body 7 is a group like the first string-shaped body 7A, storage management can be easily performed. On the other hand, if the string-shaped body 7 is separated from each other like the second string-shaped body 7B and the third string-shaped body 7C, only the string material 71 in the separated structure is used, such as when a part is consumed. Since it can be easily replaced, the maintenance cost can be reduced.
As described above, the tarp of the present invention exerts the various excellent effects described above and is extremely beneficial.

In the present invention, the present invention is not limited to the one shown in the above embodiment, and various modifications can be made within the scope of the present invention according to the purpose and application. The shape, size, number, etc. of the turret 1, the column 2, the beam member 4, the hub joint 5, the locking body 6, the string-shaped body 7, etc. can be appropriately selected according to the application. For example, although the beam member 4 is a solid rod-shaped body, it can be a pipe-shaped rod-shaped body.
