  However, for the success of various events and meetings, it is also important to create an environment where visitors and staff can enjoy the event through their five senses. There is a problem that there are few or few things that appeal directly and effectively to the visual sense of visitors and staff at events and gatherings, etc. .

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a tent that can be enjoyed visually by a user of the tent.

  In order to achieve this object, the tent of the first invention includes a tent film that is formed of a flexible sheet material and hangs downward in a windless state, and a support member that supports the tent film in the air. .

  According to the tent of the first aspect of the invention, the tent film is formed of a flexible sheet material, and the tent film is supported in the air by the support member, so that the tent film hangs down in a convex shape in the absence of wind. As a result of the atmospheric flow such as natural wind or artificial wind flowing above or below the tent film, the tent film bulges upward and protrudes downward and hangs downward and protrudes convexly. In the meantime, while the shape of the tent film is irregularly changed, the tent film can be reversed while irregularly changing the upper and lower irregularities, and the entire tent film can be swung up and down greatly.

  The tent according to a second aspect of the present invention is the tent according to the first aspect, wherein the tent film has a top surface that is concave downward in a windless state and a bottom surface that is convex downward in a windless state, and the convex bottom surface A through hole that connects the top of the concave portion and the bottom of the concave upper surface.

  According to the tent of the second invention, the tent film works in the same manner as the tent of the first invention, and the atmospheric flow flows into the lower surface side of the tent film and pushes the tent film upward so that the tent film is convex upward. When it comes to form, the atmospheric flow can escape from the lower surface side to the upper surface side of the tent membrane through the through hole, and an overload is applied to the portion connecting the tent membrane pushed up by the atmospheric flow and the support member that supports it Can prevent the tent film from being damaged.

  In addition, when the atmospheric flow flows into the upper surface side of the tent film and pushes the tent film downward, the tent film has a downwardly convex shape, so that the atmospheric flow passes through the through hole from the upper surface side to the lower surface side of the tent film. It is possible to escape, and it is possible to prevent the tent film from being damaged by preventing an overload from being applied to the portion connecting the tent film pushed down by the atmospheric flow and the support member that supports the tent film.

  A tent according to a third aspect of the present invention is the tent according to the second aspect, wherein one end of the fixing member can be attached to the through hole in a state where the fixing member hangs down below the tent film.

  The tent film 2 has a lower surface 2a that is convex downward in a windless state and an upper surface 2b that is concave downward in a windless state. The through-hole 2c penetrates from the top 2a1 of the lower surface 2a convex downward to the bottom 2b1 of the upper surface 2b concave downward.

  In addition, the through-hole 2 c has fixing members 11, 21 passing through the inner peripheral portion thereof, and hangs down below the tent film 2. One end of the fixing members 11 and 21 can be attached to the through hole 2c. One end of each of the fixing members 11 and 21 is attached to the through hole 2c, and the other end is attached to the ground G and a heavy object 13 such as a fixed object or a weight of the ground G. Alternatively, one end of the fixing member 11 is attached to the through hole 2c, and the fixing member 11 itself becomes a weight that pulls the tent film 2 downward.

  The fixing member 11 is a string-like body. The fixing member 21 is a tubular body to which the through hole 2c and the inner peripheral portion 21a are attached in communication. The fixing member may be a rod-like body that penetrates through the through hole 2c and is attached to the through hole 2c.

  FIG. 1 is a front view of the tent 1 of the present embodiment, FIG. 2 is a right side view of the tent 1, and FIG. 3 is a plan view of the tent 1. The tent 1 of the present embodiment has a left side view that is symmetrical to the right side view, except that a connecting tool 2e of a tent film 2 to be described later is wound around the connecting ring 3c of the support member 3 and connected to the back side. The figure is the same as the front view.

  As shown in FIGS. 1 to 3, the tent 1 of this embodiment includes a tent film 2 and a support member 3. As shown in FIGS. 1 and 2, the tent film 2 is formed of a sheet material that is lightweight, flexible (flexible), and waterproof, and has a lower surface 2a that protrudes downward in a windless state. And an upper surface 2b that is concave downward in a windless state.

  The tent film 2 is supported in the air by the support member 3 and is suspended above the tent installation surface G. Further, the tent film 2 is supported by the support member 3 in the air so that the tent film 2 hangs downward in a no-wind state and is supported in the air in a slack state. .

  The support member 3 supports the tent film 2 so as to be suspended in the air separated upward from the tent installation surface G. The support member 3 includes a plurality of columns 3a that support the tent film 2 and a plurality of beams 3b that connect and reinforce the columns 3a. Since all the columns 3a and the beams 3b are the same size, the productivity of the columns 3a and the beams 3b becomes efficient, and they are easy to stack during storage and transportation, and the stacked and stored state is organized. Will look like.

  The tent space 4 is a space provided between the tent film 2 supported in the air by the support member 3 and the tent installation surface G. The tent space 4 is a space where people live and stay in the tent 1, and is also a space where an air flow such as natural wind or artificial wind enters and exits.

  The ventilation opening 8 is an opening provided between the support columns 3 a and 3 a of the support member 3 in order to allow the atmospheric flow to enter and exit the tent space 4. The ventilation opening 8 includes an upper opening 8a formed between the tent film 2 and the beam 3b between the adjacent columns 3a and 3a on the upper side of the beam 3b, and an adjacent column on the lower side of the beam 3b. There is a lower opening 8b that is also used as an entrance for a person between 3a and 3a.

  An atmospheric flow entering and exiting the tent space 4 through the ventilation opening 8 pushes the tent film 2 upward (see FIG. 11A) and pushes the tent film 2 downward (see FIG. 11B). . The atmospheric flow such as natural wind and artificial wind entering and leaving the tent space 4 irregularly flips the irregularities of the upper surface 2b and the lower surface 2a of the tent film 2 and swings the tent film 2 up and down irregularly, The tent film 2 is irregularly changed from one of the forms shown in FIG. 11A or 11B to the other.

  For example, the support member 3 of the tent 1 according to the present embodiment includes four support columns 3a and four beams 3b. Each of the support pillars 3a and the beams 3b is, for example, a square member having a cross-sectional shape of 60 mm × 60 mm in length and width, and 2700 mm in the same shape. For this reason, the tent space 4 having a planar space of about 4.5 tatamis of 2700 mm square can be created as the entire tent 1.

  In addition, wood is used for the pillars 3a and the beams 3b. Compared to the tent 1 using a metal frame, the warmth and the environment are taken into consideration with respect to the feelings of those who see or touch it. Can give an impression. In addition, waste wood such as natural forest residue can be used for the wood used for the columns 3a and beams 3b.

  As shown in FIG. 3, a through hole 2 c having a square shape in plan view is formed in the center of the tent film 2 in plan view. As shown in FIGS. 1 and 2, the through-hole 2c has a top portion 2a1 of the lower surface 2a of the tent film 2 that protrudes downward in a windless state and an upper surface 2b of the tent film 2 that is recessed downward in a windless state. It penetrates so as to connect to the bottom 2b1 of the. In other words, the through-hole 2c penetrates from the top 2a1 of the convex lower surface 2a that protrudes downward in the windless state in the tent film 2 to the bottom 2b1 of the concave upper surface 2b that is recessed downward in the windless state.

  FIG. 4A is a plan view of the tent film 2 and FIG. 4B is a front view of the tent film 2. Further, the left and right side views and the rear view of the tent film 2 are the same as the front view, and the bottom view thereof is the same as the plan view.

  As shown in FIG. 4A, the tent film 2 has a square shape in plan view, and the upper end portion 2d of the tent film 2 has a frame shape surrounded by a rectangular shape in plan view at four edges. It has become. The inner peripheral part of the frame-like upper end 2d of the tent film 2 is recessed downward, and a square-shaped through hole 2c is formed in the center of the recess. Further, at the four corners of the frame-shaped upper end 2d of the tent film 2, there are provided connecting tools 2e for connecting the tent film 2 to the support member 3 for connection.

  As shown in FIG. 4B, the tent film 2 has an isosceles triangle shape on the front surface, the back surface, and the left and right side surfaces, and the outer shape is an inverted cone shape having an inverted quadrangular pyramid shape. Specifically, as shown in FIGS. 4 (a) and 4 (b), the upper surface 2b is an inverted conical concave surface having an inverted quadrangular pyramid shape in a state free from slack and distortion. Has a bottom 2b1 at the center in plan view, and its lower surface 2a is an inverted conical convex surface having an inverted quadrangular pyramid, and has a top 2a1 at the center in plan view of the convex surface.

  The outer shape of the tent film 2 is limited to an inverted conical shape having an inverted quadrangular pyramid, as long as the lower surface 2a is convex downward in a windless state and the upper surface 2b is concave in a windless state. For example, an inverted triangular pyramid, an inverted pentagonal pyramid, an inverted hexagonal pyramid, an inverted octagonal pyramid, an inverted cone or other inverted cone shape, a semi-spherical shape, a bowl shape, a chevron shape, or other undulating shape, or these A combination of undulating shapes may be used.

  In addition, by forming the tent film 2 in the shape of an inverted cone like this, the tent 1 has a space around the top 2a1 of the lower surface 2a of the tent film 2, that is, around the center of the lower surface 2a of the tent film 2. Since this space can be opened to the outside, the user can feel more open than the conventional tent 1.

  As shown in FIG. 4, the four side surfaces of the tent film 2 having an inverted quadrangular pyramid are formed of a sheet material having an isosceles triangular shape, and are linear from the upper end 2d to the apex of the inverted quadrangular pyramid. The four side portions extending in the direction are formed by stitching the edge portions of the sheet materials forming the side portions adjacent to each other of the tent film 2.

  The four side portions of the tent film 2 having an inverted quadrangular pyramid are side portions of the inverted quadrangular pyramid formed by a single sheet material by stitching the side sheets of adjacent sheet materials overlapping each other. The cartilage is harder and less flexible than the cartilage part (hereinafter referred to as “lateral cartilage part”). Although this side cartilage portion does not have the strength to support the weight of the tent membrane 2, it inhibits the movement of the tent membrane 2 and delays the change in the vertical movement of the tent membrane 2 with respect to the change in the atmospheric flow. It is.

  For example, according to each side cartilage portion of the tent membrane 2, the strength and direction of the atmospheric flow changes after blowing up, and the movement of the tent membrane 2 that tries to hang down, The deformation of the tent film 2 is delayed by hindering or inhibiting the movement of the tent film 2 that is going to blow up upwards after the strength and direction of the atmospheric flow change after hanging down. It is possible to prevent the tent film 2 from simply fluttering in a short cycle in response to minor changes in the tent film, and to slowly swing the tent film 2 up and down in a larger cycle, as if life had lived A swaying motion can be imparted to the tent film 2.

  Further, the four bottom side portions forming the upper end portion 2d having a frame shape in the plan view of the tent film 2 are extended into the cylindrical shape by folding back and sewing the bottom side portions of the sheet material forming the side surface portion of the tent film 2. It has a cylindrical shape penetrating in the direction. In addition, the four bottom portions of the upper end 2d of the tent film 2 that are formed in a cylindrical shape pass through the cylindrical inner peripheral portion so that a string-like body that becomes the connector 2e penetrates in the direction of each bottom. The string-like body which has come out from both end portions of each bottom portion having a cylindrical shape is a connecting portion 2e (see FIG. 5A).

  In this way, the upper end 2d of the tent film 2 is flexible compared to the side surface of the tent film 2 by sewing the four bottom sides into a cylindrical shape and passing the string-like body through the inner periphery thereof. It becomes difficult to bend because of the low nature. For this reason, the four bottom portions of the tent membrane 2 are also a kind of cartilage (hereinafter referred to as “bottom cartilage”). According to the four bottom cartilage portions of the tent membrane 2, there is not sufficient strength to support the weight of the tent membrane 2, but the bottom portion (upper end portion 2d) of the tent membrane 2 is reinforced so as not to be bent and drooped. Is helping to.

  5 (a) is a partially enlarged view of FIG. 4 (a) and is an enlarged plan view of the connector 2e, and FIG. 5 (b) is a partially enlarged view of FIG. 4 (a). FIG. 5C is an enlarged plan view of the through-hole 2c of the tent film 2, and FIG. 5C is a vertical cross-sectional view taken along line Vc-Vc in FIG. 5B and a cross-sectional view of the through-hole 2c.

  As shown in FIG. 5 (a), the connecting tool 2 e provided at the four corners of the tent film 2 is formed in a ring shape that is wound around the four corners of the tent film 2 through the connecting rings 3 c on the four columns 3 a of the support member 3. It is a string-like body such as a rope. In addition, although illustration is abbreviate | omitted, all the four connection tools 2e provided in the four corners of the frame-shaped upper end part 2d of the tent film | membrane 2 are the same ring-shaped string-like bodies.

  As shown in FIG. 5B, the through hole 2c is an opening having a square shape in plan view, and as shown in FIG. 5C, the through hole 2c penetrates the tent film 2 in the vertical direction.

  6 is a plan view of the support member 3, FIG. 7 is an enlarged front view of the support member 3, FIG. 8 is an enlarged right side view of the support member 3, and FIG. 7 (a) is a cross-sectional view taken along line IXa-IXa, FIG. 9 (b) is a cross-sectional view taken along line IXb-IXb in FIG. 7 (a), and FIG. 10 (a) is shown in FIG. FIG. 10A is a transverse sectional view taken along line Xa-Xa, and FIG. 10B is a transverse sectional view taken along line Xb-Xb in FIG. The back view of the support member 3 is the same as the front view, and the left side view of the support member 3 is the same as the right side view.

  As shown in FIG. 6, the support member 3 includes four support columns 3 a and four beams 3 b that connect the adjacent support columns 3 a and 3 a to each other. Each beam 3b is disposed between two adjacent columns 3a, 3a, and both end portions of each beam 3b are connected to each other via a connector 6 of the column 3a. The support member 3 is formed into a square frame body in plan view by combining the four columns 3a and the four beams 3b at the four corners, and the inner peripheral portion of the frame body is in the vertical direction (FIG. 6). The opening is a square shape in plan view penetrating in the direction perpendicular to the paper surface of the paper, and is attached so that the tent film 2 covers the entire opening (see FIG. 3).

  As shown in FIGS. 7 and 8, the four columns 3a of the support member 3 are all the same height (length), and are perpendicular to the tent installation surface G (see FIGS. 1 and 2). Standing in a posture. In addition, a fixed pile 5 that is driven into the ground is provided at the lower end of each column 3a in order to prevent the column 3a from overturning and shifting on the tent installation surface G.

  The fixed pile 5 includes a substrate 5a that is in contact with the lower end surface of the column 3a, a fixed embedding portion 5b that is a rod-like body extending vertically upward from the substrate 5a to the inside of the column 3a, and the fixed pile 5a. It is provided with a pile body portion 5c that is provided on the same axis as the embedding portion 5b and extends from the substrate 5a vertically downward (on the side opposite to the support column 3a) and has a sharp tip. The fixed embedding part 5b is a part for attaching and fixing the fixed pile 5 to the support column 3a, and the pile main body part 5c is a part that is driven into the ground of the tent installation surface G and is embedded.

  Moreover, the connection part 6 which connects the support | pillar 3a and the beam 3b, and the positioning pin 7 which positions the support | pillar 3a and the beam 3b are provided in the connection part of each support | pillar 3a and each beam 3b. As shown in FIG. 9, the connector 6 is engaged with an anchor bolt 6a that is screwed into the beam 3b from both ends thereof, a screw shaft portion that is screwed to the anchor bolt 6a, and the column 3a. And a connecting bolt 6b having a head.

  As shown in FIG. 10, the positioning pin 7 is embedded between the contact surfaces of the support column 3a and the beam 3b. One half of the positioning pin 7 contacts the side surface of the support column 3a and the other half contacts the side surface of the support column 3a. Removably inserted into the end face of the beam 3b. By inserting the positioning pin 7 between the contact surfaces of the support column 3a and the beam 3b as described above, the support column 3a and the beam 3b are connected to each other before connecting the support column 3a and the beam 3b using the connection tool 6. Can be positioned.

  Thus, by positioning the support column 3a and the beam 3b with each other, when the screw shaft portion of the connection bolt 6b is screwed into the screw hole of the anchor bolt 6a of the connector 6, the embedded hole for the connection bolt 6b opened in the support column 3a is formed. It is possible to align with the female screw hole of the anchor bolt 6a, and it becomes easy to screw the connection bolt 6b into the anchor bolt 6a.

  Further, the entire connecting tool 6 is embedded in the beam 3b without the anchor bolt 6a protruding from the end face of the beam 3b. Further, the connection tool 6 is embedded so that the head of the connection bolt 6b is flush with the side surface of the support column 3a in the assembled state of the support member 3, while the connection bolt 6b is connected to the support column 3a in the disassembled state of the support member 3. Therefore, the connecting member 6 does not protrude from the support column 3a or the beam 3b in the assembled state or the disassembled state of the support member 3, and the protrusion does not become difficult to store due to obstruction.

  In addition, all the beams 3b of the support member 3 are horizontally disposed at a predetermined height below the upper end of each support column 3a, and the height from the tent installation surface G is in most cases where people enter and exit without bending. It is possible height. For this reason, the upper end portion of the column 3a protrudes above the beam 3b, the tent film 2 is lifted above the beam 3b, and the tent film 2 also extends between the upper end portion 2d of the tent film 2 and the beam 3b. Atmospheric flow can flow into the lower side. For this reason, even if some hanging curtain or the like is attached below the beam 3b, an atmospheric flow can flow into the tent space 4, and the tent film 2 swings up and down.

Further, an annular connecting ring 3c for connecting and winding the connecting tool 2e of the tent film 2 is attached to the upper end surface of the column 3a. For example, the connection ring 3c is a suspension bolt having a ring-shaped head such as an eyebolt, and its shaft portion is screwed to the upper end surface of the column 3a.

  Next, the operation of the tent 1 of this embodiment will be described with reference to FIG. In addition, it is natural that the field tent 1 of this embodiment can be used as an awning or a rain shield as in the case of the normal tent 1, and a detailed description thereof will be omitted.

  FIG. 11A is a longitudinal sectional view of the tent 1 showing a state in which the tent film 2 is pushed upward, and FIG. 11B shows a tent 1 showing a state in which the tent film 2 hangs down. FIG. As described above, the through hole 2c of the tent film 2 penetrates from the upper surface 2b to the lower surface 2a of the tent film 2 (see FIG. 4C).

  Therefore, as shown in FIG. 11A, when the atmospheric flow flows into the tent space 4 from the ventilation opening 8 between the support columns 3a and 3a and pushes the tent film 2 upward, the tent film 2 is strongly strengthened. A part of the atmospheric flow to be pushed up can be released above the tent film 2 from the through hole 2c. In addition, as shown in FIG. 11B, when the atmospheric flow blows down from above the tent film 2 and pushes the tent film 2 downward, a part of the atmospheric flow that strongly pushes down the tent film 2 is passed through the hole. It is possible to escape from 2c to the lower side of the tent film 2 and escape from the vent opening 8 to the outside of the tent space 4.

  As described above, when the atmospheric flow passes through the through-hole 2c, it is possible to prevent the atmospheric flow from excessively increasing the force that pushes up or pushes down the tent film 2, and the tent film 2 and the support member 3 are separated by a strong atmospheric flow such as a strong wind. It is possible to prevent the tent film 2 from being damaged due to an excessive force acting on the joint, and the tent film 2 is broken.

  According to the tent 1 of the present embodiment described above, the atmospheric flow is supported in the state shown in FIG. 11B, that is, in the state where the tent film 2 is supported by the support member 3 and suspended in the air. , 3a from the ventilation opening 8 toward the tent space 4, the lower surface 2a of the tent film 2 is pushed by this atmospheric flow and the tent film 2 is pushed upward, and the state shown in FIG. That is, the bottom surface 2a of the tent film 2 is concave upward, and the top surface 2b of the tent film 2 is convex upward.

  On the other hand, the state shown in FIG. 11A, that is, the tent film 2 is pushed up by the atmospheric flow, the lower surface 2a of the tent film 2 becomes concave upward, and the upper surface 2b of the tent film 2 becomes convex upward. In this state, when the air flow flows out of the tent space 4 through the ventilation opening 8 between the support columns 3a, 3a, the tent film 2 hangs down, and the state shown in FIG. The lower surface 2a is convex downward, and the upper surface 2b of the tent film 2 changes to a downward concave shape.

  As described above, the tent 1 according to this embodiment receives an atmospheric flow such as natural wind or artificial wind, and the tent film 2 is pushed up or down. Regularly swaying up and down (ups and downs), its form can change every moment, and by such change, the movement of the wind (flow) and its strength can be visualized. By this wind visualization, it is possible to provide an environment in which a person who uses the tent 1 and a person who watches the tent 1 can feel the wind through the sight, or visually appreciate the wind that cannot be seen.

  Further, as shown in FIG. 11B, when the upper surface 2b of the tent film 2 has a concave shape, the through hole 2c collects rainwater or the like on the upper surface 2b of the tent film 2 at the bottom 2b1. Thus, it can also function as a drainage hole that drops (flows down) below the tent film 2 and drains it. Rainwater or the like drained from the upper surface 2b of the tent film 2 through the through hole 2c can be dropped directly onto the tent installation surface G.

  In this way, the upper surface 2b of the tent film 2 is concave downward, and the upper surface 2b is a slope inclined downward toward the bottom 2b1 in the center in plan view, and then the upper surface 2b. Since the through-hole 2c is formed in the bottom 2b1, the rainwater or the like can be collected along the slope of the upper surface 2b of the tent film 2 to the bottom 2b1 and concentrated and drained from the through-hole 2c.
