Description

  The present invention uses a tent main body fabric of a water-resistant and moisture-permeable processed material by coating processing, and forms a wide belt-like bottom rising portion formed around the tent front and rear surface portions and the tent left and right side portions of the tent body. It relates to a single dome tent that does not constitute a (bathtub) and eliminates the source of large condensation.

  The portable small tent used for mountain climbing, camping, etc. is an indispensable tool for protecting the human body by preventing wind and rain, for example, in the case of bad weather, in addition to sleeping and resting. This type of tent is required to be lightweight and compact in order to facilitate portability. Today, this reduction in weight and size has been achieved in a significant portion of the tent fabric, pole material, and the like.

  By the way, this tent is required to be easily assembled and installed by anyone, regardless of the installation location. In setting up a tent, it is required to quickly assemble the tent without spending time when it is urgent, such as rapid assembly, especially when the weather changes suddenly. For this reason, a self-supporting tent that is completed at the same time as the tent is lifted is preferable.

  This free-standing tent is roughly classified into three types according to the tension of the tent. One is called a suspended tent, and the tent is stretched from a stretched pole through a suitable support element such as a loop. The other is called a pole-insertable tent, and a thin tube-shaped cylinder with a pole inserted through the outer periphery of the tent is provided along the ridgeline. When the pole passes through this tube-shaped cylinder, the tent Is an external type that is stretched by the elasticity of the pole.

  Furthermore, another one is what is called a dry Ekken formula. The rope as a tension means winds the rope of the main body around the pole, the pole and the tent are evenly connected along the semicircular shape, and the tent is supported by the tension of the rope, so that an ideal operation can be performed. By the way, the dome-shaped tent components that are currently commonly used as outdoor tents are made of a thin, woven fabric made of synthetic fibers such as nylon or polyester, or cotton, and are waterproof and water repellent. ing.

  This tent material prevents wind and rain, dew, snow, etc. at the camp site, prevents stuffiness and sweating during use in the summer or extremely hot regions, and demonstrates a high thermal insulation effect during use in the winter or extremely cold regions. Conflicting requests have been made. The tent material currently marketed as a dome tent uses a fabric in which the tent main body is water-repellent and the bottom of the tent main body and the wide belt-shaped rising portion (bathtub) following the tent are waterproofed. A combination with a fly sheet that is further waterproofed on the dome tent is widely used.

  This tent fabric has a three-layer structure, the flysheet material is 2000 mm water resistant, the body is water repellent fabric, and the bottom riser (bathtub) is 3000 mm water resistant. Since it is used, there is a feeling of thickness, and since a bottom rising part (bathtub) is provided, condensation occurs in the tent. In particular, when the outside air temperature outside the tent is low, the temperature difference from the inside of the tent becomes large, and the dew condensation phenomenon in which fine water droplets adhere to the inner surface of the tent becomes prominent. In addition, this dew condensation phenomenon occurs intensively in the bottom sheet and the bottom rising part (bathtub) that are particularly waterproofed.

  The bottom sheet and the bottom rising part (bathtub) are attached so as to be continuous from the bottom part with a completely waterproof fabric. For this reason, the bottom rising portion forms part of the tent left and right side portions of the tent main body fabric and the bottom of the tent front and rear surface portions, and is joined to the tent main body fabric at the upper end portion of the bottom rising portion (for example, Patent Document 1).

  FIG. 8 is a perspective view showing an example in which such a conventional tent provided with a bottom rising portion (bathtub) is stretched. This tent is a pole insertion type dome tent, and is installed on the ground by inserting two poles 12a and 12b through thin tube-shaped tube portions 13a and 13b formed along the ridge line of the tent body 11. .

  These poles 12a and 12b are inserted into the cylindrical portions 13a and 13b so as to intersect at the top of the tent body 11. Each end of each pole 12a, 12b is exposed to the outside from the vicinity of the lower end of the cylindrical portion 13a, 13b, and is inserted into the pole locking hole 14a of the pole locking piece 14 protruding from the four corners of the lower end of the tent body 11. Inserted and held at its tension.

  In this state, an elastic tension force is generated in the poles 12a and 12b, and the tent body is raised in a tension state by receiving the tension force, and the tent can be set up.

  This dome tent is constructed by processing a synthetic fabric having a three-layer structure such as nylon and tetron, which is a waterproof tent body fabric. In this case, the bottom portion 15 and the bottom rising portion 17 are continuously connected to the bottom rising portion 17 that is continuous with the lower ends of the tent front and rear surface portions 16a and the tent left and right side surface portions 16b of the waterproof synthetic fabric (tent body fabric). Is formed.

That is, the bottom portion 15 and the bottom rising portion 17 are formed into a container shape (bathtub shape) using, for example, a completely waterproof synthetic fabric having a three-layer structure, and this is the lower ends of the tent front and rear surface portions 16a and 16a and the tent left and right side portions 16b and 16b. It is joined to the part through means such as adhesion or stitching. (Japanese Patent No. 3300689)
Japanese Patent No. 3300689

However, in the tent provided with the conventional bottom rising portion (bathtub) 17, the tent front and rear surface portions 16a and 16a and the tent left and right side portions 16b and 16b themselves are subjected to waterproof processing and anti-steaming processing. On the other hand, the bottom rising portion 17 and the bottom portion 15 that are continuous to these are completely waterproofed. The capacity of the bottom rising portion (bathtub) 17 occupies about 30% or more of the entire tent volume.
For this reason, due to the temperature difference between the inside and outside of the tent, not only condensation occurs remarkably around the bottom rising portion 17, but also condensation occurs on the inner surfaces of the tent front and rear surface portions 16 a and the tent left and right side portions 16 b.

  In particular, the boundary between the bottom rising portion 17 and the bottom portion 15 is united without a stitched portion or an adhesive portion. For this reason, as shown in FIG. 9, when the tent is installed, the boundary between the bottom 15 and the bottom rising portion 17 and the ground forms an arc P, and the cold outside wind S is generated between the ground and the bottom. P penetrates into the lower surface of the tent bottom 15 from P, and the bottom rising portion 17 (bathtub) and the bottom 15 are cooled. Therefore, there is also a problem that the bottom rising portion occupied in the tent is large on the inner surface side of the bottom 15 and the bottom rising portion 17 (bathtub), and this is a significant source of condensation.

 The tent body is made of a water-resistant / breathable layer sheet that is a thin flexible fabric woven with synthetic fibers or natural fibers, joined together with a sheet of water-resistant and moisture-permeable material by coating. Lighter than conventional three-layer fabric.

  Furthermore, as shown in FIG. 9, in the conventional tent, pole locking pieces 14 for mounting poles are attached to the four corners of the tent, and pole locking for locking the poles 12b and 12b to the tips of the pole locking pieces 14 is provided. A hole 14a is provided. For this reason, since the ends of the poles 12b and 12b are attached and the tent is stretched, a gap is created between the corner of the tent and the pole locking piece 14 that supports the pole, and the bottom portion of the tent that contacts the ground is the ground. It was not stable and the bottom area was weak, there was no sewn part, only the upper part had a large head, and it was weak against strong winds. Similar to the structure of a house without a foundation. That is, the bottom rising part is in a state where the shape of the bottom part is not understood by a swell like a wrapping cloth wrapped in a wrapping cloth with a belt shape of about 30 cm, so if a strong wind hits the bottom of the tent, the tent will not be stable, It is impossible to keep the original tent and it is vulnerable to wind and rain. For this reason, the outside wind S rises at the corners of the tent together with the bottom rising portions (bathtubs) 17 of the side surfaces of the tent, and the outside wind S enters from this direction, so that the bottom rising portions (bathtubs) 17 and Condensation at the bottom 15 is accelerated.

  Furthermore, in recent years, synthetic fabric called Gore-Tex developed by Gore, Inc. of the United States has been widely used as the tent body fabric. This synthetic fiber fabric is made of a nylon material having a three-layer structure in which a fine special film called a Gore-Tex membrane is processed into a fiber. This Gore-Tex has the function of preventing the ingress of water droplets due to rain, snow, etc., and releasing only the sweat water vapor, and has heat retention.

  However, this three-layer nylon material (GORE-TEX) also has good heat retention, so if the bottom rising part is made of waterproof fabric, it is inevitable that condensation will form inside the tent. Absent. In addition, the tent body 11 is slightly heavier than those made of nylon or Tetron, and has a problem that it is not only bulky but also expensive because it has a three-layer structure.

  The present invention solves the above-described conventional problems, and the entire tent front and rear surface portions and tent left and right side portions except the bottom portion are subjected to a coating process having a water-resistant and moisture-permeable layer integrally on a flexible fabric. The present invention provides a tent that can suppress the occurrence of condensation on the inner surface of the tent body by using the material sheet for the tent body fabric and removing the bottom rising portion (bathtub) from the tent. The present invention also provides a tent that can prevent the occurrence of condensation by using a lightweight, non-bulky, and inexpensive material.

  The single dome tent according to the first aspect of the present invention is formed by joining a sheet of a waterproof and moisture permeable material by coating to a thin flexible fabric woven with synthetic fibers or natural fibers. The tent main body fabric is formed with the water-resistant / breathable layer sheet formed, and the tent main body fabric is stretched to extend the tent front and rear surface portions and the tent left and right side portions to the tent bottom, and the tent front and rear surface portions and the tent left and right side portions. A tent bottom is disposed at the lower end edge of the belt, and a belt-like tape around the belt is interposed along the joints, and pole locking pieces are formed at the four corners where the belt-like tape is abutted. A locking hole is drilled, and the tent front and rear surface portions and the tent left and right side portions are integrally joined to the tent bottom portion by stitching or bonding with the band-shaped edge tape interposed. Both the tent front and rear surface portions, the tent left and right side portions, and the belt-like edge periphery tape and a waterproof sealing tape are joined to the inside of the bottom portion inside the tent bottom periphery, and the pole locking The belt-like rim tape is tensioned at the peripheral edge of the bottom with a tension that attaches a tent pole to the hole and stretches the tent body.

  According to the invention of claim 1, the tent body fabric is integrally joined to a thin flexible fabric woven with synthetic fibers or natural fibers by bonding a sheet of water-resistant and moisture-permeable processed material by coating processing. Since the water-resistant / moisture-permeable layer sheet is used, it is possible to construct a lightweight tent fabric that is rich in water resistance and moisture permeability.

  In addition, at the portion where the lower end of the tent front and rear surfaces and the left and right side portions of the tent and the bottom periphery are joined and sewn, a belt-like tape around the rim is lifted inward at the peripheral edge of the bottom and inwardly at the peripheral edge of the linear bottom. Therefore, when the tape around the edge is stretched, the arc portion P formed in the tent provided with the conventional bottom rising portion is not generated. Since this circular arc part P does not arise, the opportunity for the external wind S to enter the tent bottom part decreases. As a result, the temperature difference between the inside and outside of the tent can be prevented from becoming extremely large, and the occurrence of condensation can be suppressed.

  In addition, since there is no surrounding bottom rising part around the bottom hem of the tent, that is, a completely waterproof part, the temperature difference between the inside and outside of the tent becomes extremely large even when the tent body receives cold outside air. Can be avoided and the occurrence of condensation can be suppressed to the maximum.

  Furthermore, a tent body fabric is stretched against the tension of the tent pole when the tent is set up, and the tent is set up in a three-dimensional manner by attaching a belt-like rim-around tape to the periphery of the bottom. The peripheral edge of the bottom is also reinforced with the tape around the edge so that the fabric does not stretch or be distorted. In addition, a space corresponding to the unevenness of the ground is attached to the bottom portion.

  Therefore, it is possible not only to suppress the occurrence of dew condensation on the inner surface of the tent, but also to prevent the zack or clothing placed around the upper surface of the bottom from getting wet by touching the dewdrops. In addition, since the front and rear side surfaces of the tent and the left and right side surfaces of the tent are not completely waterproof, the difference in temperature between the inside and outside of the tent does not increase, and the occurrence of condensation at these portions can be suppressed.

  Also, since the pole locking holes that lock the poles are drilled at the positions where the strip-shaped tape around the tent strikes at the four corners of the tent, the tape around the edges can be attached to the pole locking holes at the corners of the tent. Is tensioned between the pole locking holes. For this reason, there is almost no gap between the construction ground and the tent bottom, and the chance of outside wind entering the tent bottom is reduced. As a result, the temperature difference between the inside and outside of the tent can be avoided from becoming extremely large.

Furthermore, since the belt-like rim tape is tensioned by the tension for tensioning the tent body, the bottom of the tent is prevented from floating from the setting ground and the outside air is prevented from entering.
The tent body is made of a water-resistant / breathable layer sheet that is a thin flexible fabric woven with synthetic fibers or natural fibers, joined together with a sheet of water-resistant and moisture-permeable material by coating. Lighter than conventional three-layer fabric.

  In the single dome tent according to the invention of claim 2, the tent bottom part, the tent front and back surface part, and the tent left and right side parts are joined together with the tent front and rear surface part and the tent left and right side parts and the tent bottom part. The two ends are folded inward with a belt-like rim tape that has been waterproofed on a thick woven fabric at the top and overlapped, and sewn or bonded to the tent front and back surfaces and the tent left and right sides In addition, the waterproof tent tape is brought into contact with and joined to the folded portion of the tent bottom along the joint between the tent front and rear surface portions and the tent left and right side portions and the tent bottom portion. Features.

  In the single dome tent according to a third aspect of the present invention, the junction between the tent bottom, the front and rear tents of the tent, and the left and right side of the tent is made to protrude by overlapping the both ends. Formed into a substantially U-shaped cross-section by folding both ends of a belt-like edge tape that has been waterproofed into a woven fabric to form a frame piece (binder processing), and aligning the frame piece of the edge tape to both ends of the main body Along the inner side of the tent front and rear surfaces, the left and right tents of the tent, and the inner side of the tent bottom, the waterproof seal is attached to the tent. The tape is joined.

  In the single dome tent according to a fourth aspect of the present invention, the junction between the tent bottom, the front and rear tents of the tent, and the left and right side of the tent protrudes by overlapping the both ends, and the overlapping part is thick. A belt-like edge tape tape that has been waterproofed to a woven fabric is bent at both ends to form a substantially U-shaped cross section, and this edge tape is applied along each end-to-end portion and sewn or sewn. In addition to being integrally bonded by bonding, a waterproof sealing tape is bonded along the bonded inner portion of the tent front and rear surface portion, the tent left and right side surface portion, and the tent bottom portion.

  According to the second to fourth aspects of the present invention, after the tent is set up using the tent pole, the tent bottom can be brought into contact with the ground on which the tent is set up by the tension force of the band-shaped edge tape. Therefore, it is possible to prevent cold outside air from entering under the bottom of the tent, and it is possible to prevent a temperature difference between the inside and outside of the tent from increasing near the bottom of the tent bottom, the front and back surfaces of the tent, and the left and right side surfaces of the tent. Accordingly, it is possible to effectively avoid the occurrence of condensation in the tent near the bottom of the tent, the front and rear surfaces of the tent, and the lower ends of the left and right side surfaces of the tent.

  Further, since the waterproof sealing tape is brought into contact with the joint inner surface portion of the connection portion between the tent front and rear surface portions and the tent left and right side portions and the tent bottom portion, water does not enter from the joint portion. A sufficient waterproof effect is also obtained.

In the present invention, since the entire tent front and rear surface portions and the tent left and right side portions excluding the tent bottom portion are made of a coating material sheet having a water-resistant and moisture-permeable layer on synthetic fibers or natural fibers, a bottom rising portion is formed. Therefore, it is possible to prevent the temperature difference between the inside and outside of the tent from increasing. That is, since the fabric of the tent body is taken into consideration in consideration of the thinness of the fabric and the water resistance, the sewn portion is reduced especially in order to keep the water resistance at the bottom of the tent. The bottom part is sewn at the four corners where two poles intersect as a dome-shaped tent structure.
Further, when the tent is set up, it is possible to suppress the intrusion of outside air into the setting ground and the bottom of the tent by tensioning the belt-like rim tape at the boundary between the bottom, the front and back sides of the tent, and the left and right sides of the tent.
Therefore, it is possible to suppress the occurrence of dew condensation on the front and back surfaces of the tent and the inner surfaces of the left and right side surfaces of the tent due to the temperature difference. Thereby, it is possible to prevent the clothes placed in the tent from getting wet by water droplets.
The tent body is made of a water-resistant / breathable layer sheet that is a thin flexible fabric woven with synthetic fibers or natural fibers, joined together with a sheet of water-resistant and moisture-permeable material by coating. It is lighter, stronger and cheaper than conventional three-layer fabrics.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 is a perspective view showing an example of a single dome tent according to an embodiment of the present invention, FIG. 2 is a plan view of the bottom of the tent shown in FIG. 1, and FIG. 3 is a pole locking hole and a strip-like edge shown in FIG. FIG. 4 to FIG. 5 are explanatory views showing an example of the joining of the belt-like edge tape and the tent bottom according to the present invention, and FIG. 6 is a belt-like edge circumference according to the present invention. FIG. 7 is a cross-sectional explanatory view showing another example of joining of the tape and the bottom of the tent, and FIG. 7 is an explanatory view showing another example of joining of the belt-like edge tape and the tent bottom according to the present invention.

  In FIG. 1, the entire tent according to the present invention is arranged such that the tent main body 1 and the upper part outside the tent main body 1 cross each other and support the tent main body 1 in a raised state. 2a, 2b, tent front and rear surface portions 1a, 1a, tent left and right side portions 1b, 1b, and a tent main body consisting of a tent bottom 3, and a belt-like edge tape 4 interposed at the periphery of the tent bottom 3 . In the figure, reference numeral 5 denotes a pole locking piece of a tent pole insertion formed at the four corners of the tent body.

  In the tent body 1, a plurality of rope support members 6 are attached at substantially equal intervals on a diagonal line on the upper surface (on a line or a ridge line along the seam between the tent front and rear surface portion 1a and the tent left and right side surface portion 1b). . A rope 7 is slidably supported by rope support members 6 provided at a plurality of locations on the diagonal line. By hooking the rope 7 on the rope support member 6 provided along the tent ridge line so that the plurality of portions of the rope 7 straddle the upper portions of the poles 2a and 2b, the tent body 1 can be seen from the poles 2a and 2b. 1 is supported. In the figure, 8 indicates an opening / closing sheet for the tent doorway.

  As shown in FIGS. 1 and 2, the tent body 1 is coated with a waterproof and moisture-permeable layer sheet integrally bonded and sewn to a thin flexible fabric woven with synthetic fibers or natural fibers. It is made of tent body fabric as a material sheet. The tent main body fabric is stretched to form the tent front and rear surface portions 1a and 1a and the tent left and right side portions 1b and 1b. A rectangular tent bottom 3 is disposed at the lower ends of the tent front and rear surface portions 1a and 1a and the tent left and right side surface portions 1b and 1b. In the present invention, the tent front and rear surface portions 1a and 1a and the tent left and right side portions 1b and 1b are extended to the tent bottom portion 3, and the lower end portion of the tent bottom portion 3 is provided with a belt-like rim-around tape 4 interposed at the peripheral portion. Join. For this reason, the bottom rising part from the tent bottom part 3 in the conventional tent is not formed.

  As shown in FIG. 2, a belt-like edge-around tape 4 is interposed between the tent front and rear surface portions 1a and 1a and the tent left and right side portions 1b and 1b at the peripheral edge of the tent bottom 3. At the four corners of the tent, a pole locking hole (grommet) 5a for attaching the tent pole and a pole locking piece 5 for the tent pole are attached to the end of the tent ridgeline 6 and the abutting portion of the belt-like edge tape 4 It has been. This pole locking hole (grommet) 5a is located at the end of the tent ridgeline 6 at the abutting portion of the belt-like edge tape 4, and when the poles 2a and 2b are inserted, tension is applied and the belt-like edge tape 4 is I get nervous in a straight line. This tension eliminates the gap between the bottom and the ground, reduces the entry of outside wind from the tent bottom 3, and prevents the occurrence of condensation.

  Further, as shown in FIGS. 4 to 7, a band-shaped waterproof waterproof sealing tape 9 is attached to the joint portion inside the peripheral edge of the tent bottom 3. The sealing tape 9 is an inner side in which the tent front and rear surface portions 1a and 1a and the tent left and right side surface portions 1b and 1b are integrally joined to the tent bottom portion 3 by stitching or bonding, with the belt-like edge tape 4 interposed therebetween. Seal the joint to prevent water from entering the joint.

  An entrance 7 is provided in one of the tent front and back surface portions 1a, and an open / close portion (open / close lid) 8 that can be opened and closed by a zipper or the like is provided in the entrance 7 as shown in FIG. A binding component 10 that binds the opening / closing part 8 wound up when the entrance is opened is attached to the lower portion of the entrance 7.

  Further, as shown in FIG. 3, the tip of the pole locking hole (grommet) 5a at the four corners of the tent corresponds to the lower ends of the connecting portions (corner portions) of the tent front and rear surface portions 1a and 1a and the tent left and right side portions 1b and 1b. A pole locking piece 5 for a tent pole is attached to the position. This pole locking piece 5 is disposed at a position on the ridge line 6 of the tent front / rear surface portion 1a and the tent left / right side surface portion 1b so as to protrude to a position where the tips of the belt-shaped edge-around tapes 4 intersect.

  A pole locking hole 5a for holding the lower ends of the tent poles 2a and 2b in an inserted state is provided at a position (butting portion) where the leading ends of the band-shaped edge-around tapes 4 are butted and intersect. This pole locking hole 5a is drilled at a portion where each belt-like edge tape 4 intersects. By inserting the tent poles 2a and 2b, tension is applied to the edge tape 4 by the elasticity of the tent poles 2a and 2b. And the tape 4 around the edge is strongly stretched in a straight line. As a result, when the tent body is set up, the belt-like edge-around tape 4 can be laid along the tent installation ground.

  Moreover, since the pole locking hole 5a exists in the site | part which the strip | belt-shaped edge periphery tapes 4 cross | intersect, it does not float by an external wind. Thus, when the tent main body 1 is set up, the belt-like rim-around tape 4 can be laid along the tent installation ground, and the floating is prevented. As a result, the cold air S is prevented from entering the tent bottom 3, and a phenomenon in which a temperature difference occurs is suppressed, and the occurrence of condensation in the tent is suppressed.

  Next, a connection structure of the tent front and rear surface portions 1a and 1a and the tent left and right side surfaces 1b and 1b and the tent bottom 3 will be described.

4 to 5 show the joint structure according to the second aspect. As shown in FIG. 4, when joining the tent front and rear surface portions 1a and 1a and the tent left and right side portions 1b and 1b and the tent bottom portion 3 by sewing 9b or adhesive 9a, the edge tape 4 is bent. Then, they are sandwiched and joined from the inside by sewing 9b or adhesive 9a. Further, the sealing tape 9 is brought into contact with the inner side to be integrated by a bonding means such as an adhesive. In this way, since the waterproof sealing tape 9 is brought into contact with the joint surface portion, water and wind do not enter the tent from the joint portion.
Adhesion is suitable for the joining method from the viewpoint of waterproofness.

FIG. 5 shows a portion of a pole locking piece (grommet) 5 having a joined structure. As shown in FIG. 5, pole locking pieces (grommets) 5 in which pole locking holes 5a are formed are arranged at the four corners of the tent. When the tent front and rear surface portions 1a and 1a and the tent left and right side portions 1b and 1b and the tent bottom portion 3 are joined together by sewing 9b or adhesive 9a, the belt-shaped edge tape 4 and the pole locking piece (grommet) 5 are sandwiched. And joined by sewing 9b or adhesive 9a. On the inner side, the sealing tape 9 is brought into contact with the inner side by means of the joining means. In this way, the pole locking pieces (grommets) 5 and the strip-shaped edge-around tape 4 are firmly integrated at the four corners.
The protruding width of the belt-like edge-around tape 4 is interposed with a width of about 2 to 5 cm, depending on the size of the tent.

  FIG. 6 shows another example of the joint structure shown in claim 3. In this joining method, as shown in FIG. 6, the joining of the tent bottom part 3, the tent front and rear surface parts 1a and 1a, and the tent left and right side parts 1b and 1b is caused to protrude by overlapping the both end face edges. The edge portions of the belt-like edge tape 4 are bent at the overlapping portion, the edge portions are folded inward, and a frame 4a having a substantially U-shaped cross section is formed. In a state of covering along the abutting portion, they are joined together by means such as stitching 4d or adhesion 4c, respectively, so as to be integrated. The waterproof sealing tape 9 is brought into contact with the tent front and rear surface portions 1a and 1a and the tent left and right side surface portions 1b and 1b along the inner side of the tent bottom 3 and bonded by bonding 9a. As described above, since the waterproof sealing tape is brought into contact, water does not enter the tent from the joint portion.

  FIG. 7 shows another example of the joint structure according to the fourth aspect. In this joining method, as shown in FIG. 7, the joining of the tent bottom part 3, the tent front and rear face parts 1a and 1a, and the tent left and right side face parts 1b and 1b is caused to protrude by overlapping the both end face edges. In the state where both ends of the belt-like edge tape 4 are bent at the overlapping portion so that the cross section is formed in a substantially U shape, the edge tape 4 is covered along the both edges, They are joined together by means such as stitching 4d or adhesion 4c. A waterproof sealing tape 9 is brought into contact with the tent front and rear surface portions 1a, 1a and the tent left and right side portions 1b, 1b and the inner side of the tent bottom 3, and bonded by bonding 9a. . As described above, since the waterproof sealing tape is brought into contact, water does not enter the tent from the joint portion.

  In the present invention, the tent poles 2a and 2b are inserted into the pole insertion holes 5a at both ends by holding the belt-like edge periphery tape 4 around the tent bottom, and in the state where the both ends are held, Each is raised in an arc shape so that the intersection is at the top. For this reason, the tension force acts on the belt-like edge-around tape 4 between the grommets 5 and 5 under the tension force of the tent poles 2a and 2b. As a result, the belt-like edge-around tape 4 is tensed in a straight line and does not come into contact with the ground during tent construction. The arc part P is not formed and lifted off the ground like the conventional rising part 17 and the periphery of the tent bottom part 15 continuous thereto.

  In these embodiments, the tent front and rear surface portions 1a and 1a and the tent left and right side surface portions 1b and 1b of the tent main body 1 are entirely made of a tent main body material of a coating material sheet in which a water-resistant and moisture-permeable layer sheet is integrally bonded. Only the tent bottom 3 is made of a completely waterproof processed material. It is also possible to join the water / moisture permeable layer sheet integrally to the bottom and use it as the bottom material.

  As the tent body fabric material, a material sheet fabric of a coating process in which a synthetic fiber fabric of nylon or Tetron or a natural fiber fabric is subjected to water resistance and moisture permeability treatment is used. Therefore, unlike the case where the tent front and rear surface portions 1a and 1a and the tent left and right side surface portions 1b and 1b are completely waterproofed, it is possible to suppress the temperature difference between the inside and outside of the tent to suppress the occurrence of the condensation.

  Further, even when the cold outside wind S is blown onto the tent body 1, the belt-shaped edge tape 4 is disposed on the outer periphery of the tent so as to follow the setting ground, so that there is a gap between the tent bottom 3 and the ground. It is difficult to generate and the external wind S as shown in FIG. Accordingly, it is possible to avoid intensive cooling of only the lower end portions of the tent front and rear surface portions 1a and 1a and the tent left and right side portions 1b and 1b and the peripheral portion of the tent bottom portion 3. As a result, dew condensation is less likely to occur on the inner surface of the corresponding part as compared to the case where a completely waterproof rising portion 17 is provided as in a conventional tent.

Further, the tent bottom 3 is formed of a water-resistant / breathable tent body fabric that has been subjected to a waterproof treatment by the same coating as the tent front and rear surface portions 1a and 1a and the tent left and right side surfaces 1b and 1b. Yes. The waterproof sealing tape 9 that is in contact with the inside of the joint prevents water from entering from the joint.
In this way, the fabric of the tent body is manufactured taking into consideration the thinness of the fabric and the water resistance, so in order to keep the water resistance particularly at the bottom of the tent, high-density nylon 40d is used as the material. Use a fabric with a water pressure of 3000 mm. In addition, a sewing portion is provided in contact with the ground.
In this regard, as shown in FIG. 9, the conventional tent bottom is in a state where the bottom shape is not understood due to a bulge wrapped in a futon with a rise of about 30 cm at the bottom. When the strong wind hits the tent, the tent is unstable and weak, and it is impossible to keep the original tent, and it is vulnerable to wind and rain.
By encircling and mounting the rim-around tape according to the present invention around the bottom, the strength can be increased, and the tent bottom can be laid along the tent installation ground, so that the invasion of wind is prevented, and the tent bottom is prevented from rising, The temperature difference in the tent and condensation can be minimized.

  In addition, since rainwater easily enters from outside, it is difficult to process the sewn portion of the tent fabric, so it has been a problem to reduce the number of sewing locations at the bottom of the tent as much as possible. In the case of an old tent with a fly sheet, if the fly sheet rains for a long time and gets wet, the fly sheet fabric gets wet and sags that contain moisture overlap with the water-repellent tent body fabric, allowing ventilation. And the disadvantage of waterproofing was solved. At the same time, due to the material defects of the complete waterproofing of the bottom rising part (bathtub) of the main body, the cause of large condensation has been eliminated.

  In this tent 1, by eliminating the tent bottom rising portion (bathtub) 17 as in a conventional tent, it is possible to greatly reduce the amount of condensation generated on the tent front and rear surface portions 1a and 1a and the tent left and right side portions 1b. I can do it. Accordingly, it is possible to effectively prevent clothes or the like installed in the tent from getting wet by water droplets that normally adhere to the inside of the tent front and rear surface portion 1a and the tent left and right side surface portions lb. Form a tent body fabric with a waterproof / breathable sheet that is integrally bonded and sewn with a waterproof / breathable material sheet by coating, and extending this material to the bottom of the tent, making it a completely waterproof fabric material It was not necessary to use fabric materials that would cause dew condensation, which is a major drawback. Because the bottom rising part (bathtub) has been eliminated and a tape around the bottom has been created, it is possible to control the temperature inside and outside the tent, greatly reducing condensation, and the temperature and humidity inside the tent are stable, providing excellent living comfort. A comfortable environment was born and a comfortable tent life became possible. Furthermore, the entire tent bottom is firmly attached to the ground with a belt-like rim tape around the bottom and is particularly well-stabilized, preventing outside air from entering between the tent bottom and the ground, and the temperature difference between the tent and outside air. Great effect to prevent it from growing. For this reason, the temperature difference between the inside and outside of the tent is not increased, and the occurrence of condensation inside the tent can be suppressed to the maximum, and the effect of making the tent life more comfortable is enhanced.

  Further, the tent bottom part 3 is formed of a tent body fabric similar to the tent front and rear surface parts 1a and 1a and the tent left and right side parts 1b and 1b, which is waterproofed. The waterproof sealing tape 9 inside the joint prevents water from entering from the joint. This sealing tape 9 is composed of a belt-like member having high water resistance and high tensile strength.

  In a mountain tent, by eliminating the rising portion (bathtub) 17 as in a conventional tent, the amount of condensation on the tent front and rear surface portions 1a and the tent left and right side portions 1b can be suppressed to a small amount. Accordingly, it is possible to effectively prevent clothes or the like installed in the tent from getting wet by water droplets adhering to the inside of the tent front / rear surface portion 1a or the tent left / right side surface portion 1b.

  The tent body 1 having the above structure is a fly sheet made of nylon or tetron material that is waterproof and water repellent according to the period of use, for the purpose of more living space and comfortable use conditions such as rainy weather. Alternatively, in the cold winter season, the temperature and humidity of the tent body can be appropriately controlled by using the outer layer together.

  Thus, in the present invention, a thin flexible fabric made of synthetic fibers or natural fibers is integrally provided with a water / moisture permeable layer having a predetermined water pressure resistance and moisture permeability performance to form a tent body fabric, With this tent body fabric, the tent front and rear surface portions 1a and the tent left and right side surface portions 1b excluding the tent bottom 3 were formed.

As a result, it is not necessary to provide a completely waterproof rising portion at a portion where the lower part of the tent front and rear surface portion 1a and the tent left and right side surface portion 1b and the tent bottom 3 periphery are continuous, and the tent body 1 receives a cold outside wind. In addition, it is possible to avoid an extremely large temperature difference between the inside and outside of the tent with the wind-affected part as the center.

  Therefore, it is possible to suppress the occurrence of dew condensation on the inner surface of the tent and prevent the zack, clothing, etc. around the tent bottom 3 from getting wet by touching the water droplets. Moreover, since it is lightweight and not bulky, it is suitable for use as a mountain tent.
