The present invention relates to a string fixing device used when string-like members are stretched between a plurality of members.

BACKGROUND ART Among tents installed outdoors, there is a tent in which a suspended roof-like interior space is formed by tent fabric arranged between pillars (see, for example, Patent Document 1).

JP2008-57221A

In order to improve productivity in the office, it is conceivable to change the office space to one that resembles an open space. Camping is a typical example of an open space. Therefore, in order to transform an office space into an open space, there is a method of setting up a tent, which is the most distinctive feature of camping, in an office space and arranging a desk etc. inside the tent.

Therefore, there is a method of installing outdoor tents in office spaces, but many office spaces have firefighting facilities such as sprinklers installed on the ceiling. A typical tent has a roof, so if the tent is installed in an office space, water from sprinklers will not be sprayed inside the tent. In this regard, the Fire Service Act regulates the installation of facilities in office spaces that may interfere with water spraying.

Therefore, in order to change the office space into an open space by installing a tent in an office space while complying with fire regulations, it is necessary to install the side part of the tent in the office space instead of installing the entire tent in the office space. By doing so, it is possible to create an open space with the image of camping in the office space.

In that case, an opening that opens upward will be formed in the roof of the tent, but by arranging a plurality of short width sheets spaced apart from each other in the opening, the opening that opens upward can be formed. Despite having a tent, you can now get a moderate sense of cover.

Therefore, the inventor of the present invention considered installing a screw in the upper part of the frame that forms the roof of the tent, and using the screw to stretch a string-like member from which a plurality of short sheets are suspended. . However, when the string-like member is stretched using screws set on the upper part of the frame, there is a problem that the work of attaching the string-like member is complicated and the string-like member easily loosens.

Note that the above problem occurs not only when the string-like member is stretched between frames forming the roof of the tent, but also when the string-like member is stretched between a plurality of members.

On the side surface of the inner protruding part 54, eight second holding parts _54a1 protruding outward are formed at approximately equal intervals. The eight second clamping parts 54a ₁ are the four second clamping parts 54a that respectively protrude toward the first outer protrusion 52a, the second outer protrusion 52b, the first outer protrusion 53a, and the second outer protrusion 53b. Contains ₁ . The second holding portion _54a1 is formed to extend from the surface of the main body portion 51. The second holding portions 54a ₁ each have a triangular prism shape, and the width decreases toward the tip and becomes sharp.

The fitting attachment part 55 is a member that fits into the holes 33a' and 33b' formed in the horizontal frames 33a and 33b of the tent 1 to attach the string fixing device 50 to the horizontal frames 33a and 33b. The horizontal frames 33a, 33b are cylindrical members, and the holes 33a', 33b' of the horizontal frames 33a, 33b have an elliptical shape. The longitudinal direction of the holes 33a', 33b' is parallel to the longitudinal direction of the horizontal frames 33a, 33b.

As shown in FIG. 9, the fitting attachment portion 55 has an elliptical shape that is approximately the same shape as the holes 33a' and 33b' of the horizontal frames 33a and 33b, and its long axis direction is parallel to that of the main body portion 51. It is parallel to the long side direction. As shown in FIG. 7, a stepped portion 55a is formed near the root of the fitting attachment portion 55, and the portion closer to the root than the stepped portion 55a has a smaller diameter than the portion closer to the tip than the stepped portion 55a. . The diameter of the part closer to the base than the step 55a is approximately the same as the diameter of the holes 33a', 33b' of the horizontal frames 33a, 33b, and the diameter of the part closer to the tip of the horizontal frame 33a, 33b is the same as the diameter of the part closer to the tip than the step 55a. It is larger than the diameter of the holes 33a' and 33b'. The length of the portion closer to the base than the stepped portion 55a is approximately the same as the thickness of the horizontal frames 33a, 33b to which the string fixture 50 is attached.

The fitting attachment portion 55 has a through hole 55b extending in the long side direction of the main body portion 51, as shown in FIG. The through hole 55b has a substantially rectangular cross-sectional shape, and is formed from a portion closer to the root portion than the step portion 55a to a portion closer to the tip end side of the step portion 55a. Therefore, when the fitting attachment part 55 is inserted into the holes 33a' and 33b' of the horizontal frames 33a and 33b, the fitting attachment part 55 is deformed and the through hole 55b is reduced. has a smaller diameter and is disposed inside the horizontal frames 33a, 33b.

Thereafter, the diameter of the portion closer to the distal end than the stepped portion 55a returns inside the horizontal frames 33a, 33b, and becomes larger than the diameter of the holes 33a', 33b' of the horizontal frames 33a, 33b. Therefore, the fitting attachment portion 55 will not come off from the holes 33a', 33b' of the horizontal frames 33a, 33b. At this time, since the portion closer to the base than the stepped portion 55a is approximately the same as the diameter of the holes 33a', 33b' of the horizontal frames 33a, 33b, it fits into the holes 33a', 33b' of the horizontal frames 33a, 33b. match. Therefore, the string fixture 50 is attached to the outer peripheral surfaces of the horizontal frames 33a, 33b.

Regarding the method of stretching the string member 6 to the roof part 3 of the tent 1 using the string fixing devices 50 each fixed to the upper part of the four horizontal frames 33a arranged apart in the longitudinal direction of the tent 1, This will be explained based on FIG. Note that the method for stretching the string member 6 across the roof portion 3 of the tent 1 is also similar using the string fixing devices 50 fixed to the upper portions of the four horizontal frames 33b, respectively.

First, the string-like member 6 is attached to the string fixture 50 fixed to the upper part of the horizontal frame 33a that is disposed closest to the front among the four horizontal frames 33a. That is, as shown in FIG. 10(a), one end 6a of the string member 6 is inserted between the first outer protrusion 52a and the second outer protrusion 52b, and the outer circumference of the inner protrusion 54 is rotated clockwise. After winding it around, it is passed between the first outer protrusion 53a and the second outer protrusion 53b. As a result, one end 6a of the string member 6 is fixed to the string fixture 50.

At that time, the string-like member 6 passing between the first outer protruding part 52a and the second outer protruding part 52b is connected to the first holding part _52a1 of the first outer protruding part 52a and the first holding part 52a1 of the second outer protruding part 52b. The string-like member ₆ , which passes below the first clamping part 52b1 and between the first outer protrusion 53a and the second outer protrusion 53b, is attached to the first clamping part _53a1 of the first outer protrusion 53a. and passes below the first clamping part _53b1 of the second external protrusion 53b. This prevents the string-like member 6 from coming off between the first outer protrusion 52a and the second outer protrusion 52b and between the first outer protrusion 53a and the second outer protrusion 53b.

Further, the string-like member 6 wound around the outer circumference of the inner protrusion 54 is pressed toward the first clamping part _54a1 of the inner protrusion 54, and the string-like member 6 extends in the circumferential direction of the inner protrusion 54. Prevented from moving.

Subsequently, the string-like member 6 is attached to the string fixture 50 fixed to the upper part of the horizontal frame 33a adjacent to the back side of the horizontal frame 33a disposed closest to the front side. That is, as shown in FIG. 10(b), after fixing one end of the string-like member 6 to the horizontal frame 33a disposed closest to the front side, the string-like member 6 is stretched to the back side while being stretched with an appropriate tension. It is fixed to a string fixture 50 fixed to the upper part of the adjacent horizontal frame 33a. After inserting the string-like member 6 between the first outer protrusion 52a and the second outer protrusion 52b and along a part of the outer circumference of the inner protrusion 54, the first outer protrusion 53a and the second outer protrusion 53a are inserted. and the protrusion 53b. Thereby, the middle portion of the string-like member 6 is fixed to the string fixture 50.

At that time, in the same way as described above, the string member 6 is inserted between the first outer protrusion 52a and the second outer protrusion 52b and between the first outer protrusion 53a and the second outer protrusion 53b. This prevents the string member 6 from coming off, and also prevents the string member 6 from moving in the circumferential direction of the inner protrusion 54.

Subsequently, the string-like member 6 is attached to the string fixture 50 fixed to the upper part of the horizontal frame 33a adjacent to the back side. The method is similar to the method described in FIG. 10(b).

Thereafter, the string-like member 6 is attached to a string fixing device 50 fixed to the upper part of the horizontal frame 33a disposed on the rearmost side. That is, as shown in FIG. 10(c), the string-like member 6 is inserted between the first outer protrusion 52a and the second outer protrusion 52b, and the outer circumference of the inner protrusion 54 is wound clockwise. After that, it is passed between the first outer protrusion 53a and the second outer protrusion 53b. Thereby, the other end 6b of the string member 6 is fixed to the string fixture 50.

At that time, in the same way as described above, the string member 6 is inserted between the first outer protrusion 52a and the second outer protrusion 52b and between the first outer protrusion 53a and the second outer protrusion 53b. This prevents the string member 6 from coming off, and also prevents the string member 6 from moving in the circumferential direction of the inner protrusion 54.

As described above, the string fixing device 50 of the present embodiment includes a main body 51 and two protrusions 52 and 53 that protrude from the surface 51 of the main body and are arranged to face each other.

The string-like member 6 can be fixed by making it difficult for the string member 6 to move in the circumferential direction of the outer protrusions 52a, 52b, 53a, and 53b.

In the string fixing device 50 of this embodiment, the first clamping parts 52a ₁ , 52b ₁ , 53a ₁ , 53b ₁ are formed apart from the surface of the main body.

As a result, in the string fixing device 50 of this embodiment, the width of the gap between the first outer protrusion 52a and the second outer protrusion 52b and between the first outer protrusion 53a and the second outer protrusion 53b is as follows. It is large near the surface of the main body part and becomes small at the part where the first clamping parts 52a ₁ , 52b ₁ , 53a ₁ , 53b ₁ are formed on the tip side of the protrusion, so that the string-like member 6 passing through the gap is By arranging it near the surface of the main body, it is possible to prevent the string-like member 6 from coming off from within the gap.

(Second embodiment)
The difference between the indoor tent 301 of this embodiment and the indoor tent 1 of the first embodiment is that the indoor tent 1 has a substantially rectangular shape in plan view, whereas the indoor tent 301 has a substantially rectangular shape in plan view. The point is that it has a substantially octagonal shape.

As shown in FIG. 11, the indoor tent 301 has a substantially octagonal shape in plan view, and an entrance portion P is formed on the side surface thereof. Hereinafter, the description will be made assuming that the side surface of the tent 1 where the entrance portion P is formed is the front side.

As shown in FIG. 12, a frame structure 302 that forms the framework of the tent 301 includes eight vertical supports 310, a lower frame portion 320 located at the bottom of the tent 301, and a frame structure 302 located above the eight vertical supports 310. 3, and an upper frame portion 331 disposed above the frame portion 330.

The eight vertical struts 310 include two vertical struts 310a arranged on both sides of the entrance part P and six vertical struts 310b arranged at equal intervals between the two vertical struts 310a. There is. The eight vertical columns 310 are arranged so that their upper ends are inclined closer to the center of the tent than their lower ends. The eight vertical supports 310 all have substantially the same length, and their upper ends are arranged on the same horizontal plane.

The lower frame portion 320 connects the lower portions of the eight vertical columns 310 and has a substantially octagonal shape that is the same as the planar shape of the tent 301. Note that the lower frame 320 is not disposed between the two vertical supports 310a disposed on both sides of the entrance portion P.

The frame portion 330 connects the upper ends of the adjacent vertical columns 310, and has a substantially octagonal shape that is the same as the planar shape of the tent 301. As described above, since the upper ends of the eight vertical columns 310 are arranged on the same horizontal plane, the frame-shaped portion 330 is arranged substantially parallel to the horizontal plane.

The upper frame portion 331 has eight horizontal frames 332. The eight horizontal frames 332 extend from the corners of the substantially octagonal planar shape toward the central portion 335 of the tent 1. Each of the eight horizontal frames 332 has a curved portion 332a ₁ that extends upward from the frame-shaped portion 330 and then curves in the horizontal direction. In the horizontal frame 332, a portion closer to the center portion 335 of the tent 301 than the curved portion _332a1 is substantially linear, and is inclined so as to be disposed upward as it approaches the center portion 335 of the tent 301.

The indoor tent 301 has a roof portion 303 placed on the top of the tent 301 and a sheet member 312 attached to the side surface of the tent 301.

The roof portion 303 includes a frame portion 330 and a plurality of horizontal frames 332 included in the frame structure 302, an annular sheet 305, and a plurality of short sheets 306a.

The annular sheet 305 is stretched over the entire circumference of the tent 301 along the frame portion 330. The annular sheet 305 is integrally formed in a continuous annular shape, and has a substantially octagonal opening 305a.

The annular sheets 305 are arranged on each of the eight sides of the tent 301 so as to extend upward from the outer periphery of the frame portion 330 and cover the curved portion 332a ₁ of the horizontal frame 332.

The plurality of short sheets 306a have a rectangular shape with a predetermined width, and are arranged at the upper part of the tent 301 along the sides of the tent 301 while being spaced apart from each other. Specifically, two short sheets 306a are arranged parallel to each other between two adjacent horizontal frames 332, respectively. The short sheet 306a is suspended from a string member 306 stretched between two adjacent horizontal frames 332. The surface of the short sheet 306a is arranged parallel to the vertical direction in a state where it is suspended from a string-like member.

On the side surface of the frame structure 302, as shown in FIG. 12, a side surface gap 311 is formed between adjacent vertical columns 310, but in the indoor tent 301, as shown in FIG. A side sheet 312 covering 311 is attached. In FIG. 12, only the three side gaps 311 disposed on the front side of the tent 301 are labeled among the eight side gaps 11 formed between adjacent vertical columns 10.

Eight side gaps 311 are formed in the frame structure 302 of the indoor tent 301, and as shown in FIG. 311, no side sheet 312 is arranged. Therefore, at the front of the indoor tent 301, the interior space of the tent 301 and the exterior space communicate with each other.

The side sheet 312 has approximately the same size as one side cavity 311 . The side sheet 312 is formed so as to close substantially the entire area of the side surface gap 311 when attached to cover the side surface gap 311 .

The roof portion 303 always has an opening A that is open upward, as shown in the plan view of the indoor tent 301 in FIG. The opening A allows the interior space of the tent 301 and the exterior space above the tent 301 to communicate with each other.

Since the roof portion 303 includes an annular sheet 305 attached to the frame structure 302 and a plurality of short width sheets 306a, the size of the opening A is calculated from the area of the opening 305a of the annular sheet 305. This is the area obtained by subtracting the total area of the plurality of horizontal frames 332 within the opening 305a of the sheet 305 and the area of the plurality of short width sheets 306a. In this embodiment, the ratio of the size of the opening A to the installation area of the tent 301 (the size of the lower frame portion 320) shown in plan view in FIG. 13 is 30% or more.

Regarding the method of stretching the string member 306 to the roof portion 303 of the tent 301 using the string fixing devices 50 each fixed to the upper part of eight horizontal frames 333a arranged apart in the circumferential direction of the tent 301, This will be explained based on FIG. 14. FIG. 14 illustrates three horizontal frames 333a among eight horizontal frames 333a. In the second embodiment as well, the string member 306 is stretched over the roof 303 of the tent 301 using the string fixing device 50 described in the first embodiment.

That is, as shown in FIG. 14(a), one end 306a of the string member 306 is inserted between the first outer protrusion 52a and the first outer protrusion 53a, and the first outer protrusion 53a and the second outer protrusion 53a are connected to each other. After passing between the first outer protrusion 53b and the first outer protrusion 53b, the outer periphery of the first outer protrusion 53a is wound clockwise. As a result, one end 306a of the string member 306 is fixed to the string fixture 50.

At that time, the string-like member 306 passing between the first outer protruding part 53a and the second outer protruding part 53b is connected to the first holding part _53a1 of the first outer protruding part 53a and the first holding part 53a1 of the second outer protruding part 53b. 1 clamping portion 53b Passes below ₁ . This prevents the string-like member 6 from coming off from between the first outer protrusion 53a and the second outer protrusion 53b.

Moreover, the string-like member 306 passing between the first outer protruding part 52a and the first outer protruding part 53a is connected to the first holding part 52a2 of the first outer protruding part 52a and the first holding part _52a2 of the first outer protruding part 53a. They are pressed toward each other by the holding portions _53a2 . Thereby, the string member 6 is strongly fixed between the first outer protrusion 52a and the first outer protrusion 53a.

Subsequently, the string-like member 306 is attached to the string fixture 50 fixed to the upper part of the horizontal frame 333a adjacent to the right. That is, as shown in FIG. 14(b), after fixing one end 306a of the string-like member 306 to the horizontal frame 333a, while tensioning the string-like member 306 with an appropriate tension, connect the horizontal frames 333a adjacent to the right. It is fixed to a string fixture 50 fixed to the upper part. After inserting the string-like member 306 between the first outer protrusion 52a and the second outer protrusion 52b and along a part of the outer circumference of the inner protrusion 54, the first outer protrusion 53a and the second outer protrusion 53a are inserted. and the protrusion 53b. Thereby, the middle portion of the string-like member 306 is fixed to the string fixture 50.

At that time, the string-like member 306 passing between the first outer protruding part 52a and the second outer protruding part 52b is connected to the first holding part _52a1 of the first outer protruding part 52a and the first holding part 52a1 of the second outer protruding part 52b. The string-like member 306, which passes below the first clamping part _52b1 and between the first outer protrusion 53a and the second outer protrusion 53b, is attached to the first clamping part _53a1 of the first outer protrusion 53a. and passes below the first clamping part _53b1 of the second external protrusion 53b. This prevents the string member 306 from coming off from between the first outer protrusion 52a and the second outer protrusion 52b and between the first outer protrusion 53a and the second outer protrusion 53b.

Further, the string member 306 along the outer periphery of the inner protrusion 54 is pressed toward the first holding part _54a1 of the inner protrusion 54, and the string member 306 moves in the circumferential direction of the inner protrusion 54. This will prevent you from doing so.

Subsequently, the string-like member 6 is attached to the string fixing device 50 fixed to the upper part of the horizontal frame 333a adjacent to the right, and as shown in FIG. The intermediate portion of the string member 306 is similarly fixed to the string fixing tool 50 up to the horizontal frame 333a adjacent to the left side of the horizontal frame 333a to which one end 306a of the string member 306 is fixed. The method is similar to the method described in FIG. 15(b).

Thereafter, the other end 306b of the string member 6 is attached to the horizontal frame 333a to which the one end 306a of the string member 306 is fixed. That is, as shown in FIG. 14(a), the string-like member 6 is inserted between the first outer protrusion 52a and the second outer protrusion 52b, and the second outer protrusion 52b and the second outer protrusion 53b are inserted. After the second outer protrusion 52b is passed through, the outer periphery of the second outer protrusion 52b is wound counterclockwise. As a result, the other end 306b of the string member 306 is fixed to the string fixture 50.

At that time, as described above, the string-like member 306 is prevented from coming off from between the first outer protrusion 52a and the second outer protrusion 52b, and the string-like member 306 is prevented from coming off the inner protrusion 52. movement in the circumferential direction is prevented.

In that case, the string-like member can be prevented from coming off from between the protrusions. The same applies to the string fixture 150.

In the first embodiment, the string fixing device 50 is attached to the horizontal frames 33a, 33b by the fitting attachment portion 55 protruding from the back surface of the main body portion 51, but the method for attaching the string fixing device 50 to the horizontal frames 33a, 33b is Optional. When the fitting attachment part 55 is attached to fit into the holes 33a', 33b' of the horizontal frames 33a, 33b, the shape of the holes 33a', 33b' and the shape of the fitting attachment part 55 are arbitrary. be.

The present invention relates to a string fixing device used when string-like members are stretched between a plurality of members.

BACKGROUND ART Among tents installed outdoors, there is a tent in which a suspended roof-like interior space is formed by tent fabric arranged between pillars (see, for example, Patent Document 1).

JP2008-57221A

In order to improve productivity in the office, it is conceivable to change the office space to one that resembles an open space. Camping is a typical example of an open space. Therefore, in order to transform an office space into an open space, there is a method of setting up a tent, which is the most distinctive feature of camping, in an office space and arranging a desk etc. inside the tent.

Therefore, there is a method of installing outdoor tents in office spaces, but many office spaces have firefighting facilities such as sprinklers installed on the ceiling. A typical tent has a roof, so if the tent is installed in an office space, water from sprinklers will not be sprayed inside the tent. In this regard, the Fire Service Act regulates the installation of facilities in office spaces that may interfere with water spraying.

Therefore, in order to change the office space into an open space by installing a tent in an office space while complying with fire regulations, it is necessary to install the side part of the tent in the office space instead of installing the entire tent in the office space. By doing so, it is possible to create an open space with the image of camping in the office space.

In that case, an opening that opens upward will be formed in the roof of the tent, but by arranging a plurality of short sheets spaced apart from each other in the opening, the opening that opens upward can be formed. Despite the tent, you can still feel a sense of shielding.

Therefore, the inventor of the present invention considered installing a screw in the upper part of the frame that forms the roof of the tent, and using the screw to stretch a string-like member from which a plurality of short sheets are suspended. . However, when the string-like member is stretched using screws set on the upper part of the frame, there is a problem that the work of attaching the string-like member is complicated and the string-like member easily loosens.

Note that the above problem occurs not only when the string-like member is stretched between frames forming the roof of the tent, but also when the string-like member is stretched between a plurality of members.

SUMMARY OF THE INVENTION An object of the present invention is to provide a string fixing tool that facilitates the work of fixing a string-like member and that can fix the string-like member so that it does not loosen when the string-like member is stretched between a plurality of members. do.

The string fixing device according to the present invention includes a main body, and two adjacent external protrusions that protrude from the surface of the main body and are arranged to face each other, and between the two adjacent external protrusions, A gap is formed through which the string-like member passes, and a first clamping part is formed on each side of the two adjacent external protrusions to project toward the other external protrusion. is curved along the outer peripheral surface of the attached member, which is a cylindrical member, and protrudes from the back surface of the main body portion, and is a fitting attachment for fitting into an elliptical hole formed in the attached member. The fitting attachment portion has an elliptical shape that is substantially the same as the hole portion.

As a result, in the cord fixing device according to the present invention, the first clamping portions that protrude toward the other protrusion are formed on the side surfaces of the two protrusions arranged to face each other, and the cord-like member protrudes. The string-like member can be fixed by making it difficult to move in the circumferential direction of the part. Therefore, the work of fixing the string-like member to the string fixing device is easy, and the string-like member can be fixed to the string fixing device without loosening.
Moreover, with the string fixing device according to the present invention, the string fixing device can be easily attached to the member to be attached.

Thereby, with the string fixing device according to the present invention, it is possible to prevent the string fixing device from rotating relative to the attached member after the string fixing device is attached to the attached member.

Thereby, in the string fixing device according to the present invention, the string fixing device can be attached to the outer circumferential surface of the cylindrical member without any gaps.

As shown in FIG. 2, the frame structure 2 that forms the framework of the tent 1 includes 12 vertical supports 10, a lower frame part 20 located at the bottom of the tent 1, and the upper part of the 12 vertical supports 10. and an upper frame portion 31 disposed above the frame portion 30.

The 12 vertical struts 10 include two vertical struts 10a arranged on both sides of the entrance part P, four vertical struts 10b arranged on the left side, and four vertical struts 10b arranged on the right side. 10c, and two vertical supports 10d arranged on the back. The front vertical support 10a is inclined so that its upper end is closer to the back than its lower end, the rear vertical support 10d is inclined so that its upper end is closer to the front than its lower end, and the left side vertical support 10b is The vertical support 10c on the right side is inclined so that its upper end is closer to the right side than its lower end, and the vertical support 10c on the right side is arranged so that its upper end is inclined closer to the left side than its lower end. The twelve vertical supports 10 all have substantially the same length, and their upper ends are arranged on the same horizontal plane.

The lower frame portion 20 connects the lower portions of the twelve vertical columns 10 and has a substantially rectangular shape that is the same as the planar shape of the tent 1. Note that the lower frame 20 is not disposed between the two vertical supports 10a disposed on both sides of the entrance portion P.

The frame portion 30 connects the upper ends of the adjacent vertical columns 10, and has a substantially rectangular shape that is the same as the planar shape of the tent 1. As described above, since the upper ends of the twelve vertical columns 10 are arranged on the same horizontal plane, the frame-shaped portion 30 is arranged substantially parallel to the horizontal plane.

The upper frame portion 31 has a plurality of horizontal frames 32. The plurality of horizontal frames 32 include four horizontal frames 33a and four horizontal frames 33b arranged substantially parallel to the short side direction of the tent 1, and three horizontal frames 33b arranged substantially parallel to the long side direction of the tent 1. The tent includes a horizontal frame 34, two horizontal frames 35 disposed on the front side of the tent 1, and two horizontal frames 36 disposed on the back side of the tent 1.

The horizontal frame 33a and the horizontal frame 33b respectively connect the four connection parts of the vertical support 10b on the left side to the frame-shaped part 30 and the four connection parts of the vertical support 10c on the right side to the frame-like part 30, respectively. They are arranged along the shorter sides of the tent 1. The horizontal frame 33a and the horizontal frame 33b each have curved portions 33a ₁ and 33b ₁ that extend upward from the frame portion 30 and then curve toward the horizontal direction.

The horizontal frame 33a and the horizontal frame 33b, which are arranged substantially on the same straight line, are connected at the center of the tent 1 in the short side direction. In the horizontal frame 33a and the horizontal frame 33b, a portion closer to the center of the tent 1 in the short side direction than the curved portions 33a ₁ and 33b ₁ is approximately linear, and is arranged upward as it approaches the center of the tent 1 in the short side direction. It is inclined to be.

The connecting portions of the horizontal frame 33a and the horizontal frame 33b are connected by a horizontal frame 34, respectively. Therefore, the three horizontal frames 34 are arranged along the long side direction of the tent 1 at the center of the tent 1 in the short side direction. The four horizontal frames 33a are arranged on the left side of the tent 1 relative to the center in the short side direction, and the four horizontal frames 33b are arranged on the right side of the tent 1 rather than the center in the short side direction. .

The indoor tent 1 has a roof part 3 placed on the top of the tent 1 and a sheet member 12 attached to the side surface of the tent 1.

The roof portion 3 includes a frame portion 30 and a plurality of horizontal frames 32 included in the frame structure 2, an annular sheet 5, and a plurality of short sheets 6a.

The annular sheet 5 is stretched over the entire circumference of the tent 1 along the frame portion 30 in the upper part of the tent 1. The annular sheet 5 is integrally formed in a continuous annular shape, and has a substantially rectangular opening 5a.

The annular sheet 5 is disposed in the front of the tent 1 so as to extend upward from the outer periphery of the frame portion 30 and close the space between the frame portion 30 and the horizontal frames 33a, 33b closest to the front side. Similarly, the annular sheet 5 is arranged on the back side of the tent 1 so as to extend upward from the outer periphery of the frame part 30 and close the space between the frame part 30 and the horizontal frames 33a, 33b closest to the back side. Ru.

Further, the annular sheet 5 is disposed on the left and right side surfaces of the tent 1 so as to extend upward from the outer peripheral part of the frame-shaped part 30 and cover the curved parts 33a ₁ and 33b ₁ of the horizontal frames 33a and 33b. .

The plurality of short sheets 6a have a rectangular shape with a predetermined width, and are arranged in the upper part of the tent 1 along the long side direction of the tent 1 while being spaced apart from each other. Specifically, four short sheets 6a are arranged parallel to each other between two adjacent horizontal frames 33a and between two adjacent horizontal frames 33b. As shown in FIG. 3, the short sheet 6a is suspended from a string member 6 stretched between two adjacent horizontal frames 33a and between two adjacent horizontal frames 33b.

The string-like member 6 is stretched between two adjacent horizontal frames 33a and between two adjacent horizontal frames 33b so as not to loosen by a string fixing device 50 attached to the upper part of the horizontal frame 33a and the horizontal frame 33b. There is.

The surface of the short sheet 6a is arranged parallel to the vertical direction in a state where it is suspended from the string-like member 6. The short sheet 6a is, for example, a cloth sheet or a resin sheet, but the material of the short sheet 6a is arbitrary.

On the side surface of the frame structure 2, as shown in FIG. 2, a side gap 11 is formed between adjacent vertical columns 10, but in the indoor tent 1, as shown in FIG. A side sheet 12 covering 11 is attached. In FIG. 2, among the ten side cavities 11 formed between adjacent vertical columns 10, only the six side cavities 11 arranged on the front and right sides of the tent 1 are labeled. .

In the frame structure 2 of the indoor tent 1, 12 side gaps 11 are formed, and as shown in FIG. 11 and the side sheet 12 is not arranged in the side gap 11 formed between the two vertical columns 10d arranged on the back side thereof. Therefore, at the front and back sides of the indoor tent 1, the interior space and the exterior space of the tent 1 communicate with each other.

That is, in the indoor tent 1, between the vertical support 10a placed at the front and the vertical support 10b placed closest to the front on the left side, between the four vertical support 10b placed on the left side, and between the left side Between the vertical support 10b placed on the rearmost side of the right side and the vertical support 10d placed on the back, between the vertical support 10b placed on the rearmost side of the right side and the vertical support 10d placed on the back, Ten side voids 11 are formed between the four vertical columns 10c arranged on the right side, between the vertical column 10a arranged on the front and the vertical column 10c arranged on the frontmost side of the right side. A side sheet 12 is attached to cover each side cavity 11.

The side sheet 12 has approximately the same size as one side cavity 11 . The side sheet 12 is, for example, a cloth sheet or a resin sheet, but the material of the side sheet 12 is arbitrary. The side sheet 12 is formed so as to close substantially the entire area of the side surface gap 11 when attached to cover the side surface gap 11 .

As shown in the plan view of the indoor tent 1 in FIG. 4, the roof portion 3 always has an opening A that is open upward. The opening A allows the interior space of the tent 1 and the exterior space above the tent 1 to communicate with each other.

Since the roof part 3 has an annular sheet 5 attached to the frame structure 2 and a plurality of short sheets 6a, the size of the opening A is calculated from the area of the opening 5a of the annular sheet 5. This is the area obtained by subtracting the total area of the plurality of horizontal frames 32 within the opening 5a of the sheet 5 and the area of the plurality of short width sheets 6a. In this embodiment, the ratio of the size of the opening A to the installation area of the tent 1 (the size of the lower frame portion 20) shown in the plan view of FIG. 4 is 30% or more.

Therefore, a gap through which the string-like member 6 passes is formed between the first outer protrusion 52a and the first outer protrusion 53a, and a gap is formed between the second outer protrusion 52b and the second outer protrusion 53b. A gap is formed through which the string-like member 6 passes.

That is, on the surface of the main body portion 51, a first outer protrusion 52a, a second outer protrusion 52b, a first outer protrusion 53a, and a second outer protrusion 53b are formed apart from each other. The first outer protrusion 52a and the second outer protrusion 52b and the first outer protrusion 53a and the second outer protrusion 53b are arranged substantially symmetrically. Therefore, gaps through which the string member 6 passes are formed between adjacent protrusions of the first outer protrusion 52a, the second outer protrusion 52b, the first outer protrusion 53a, and the second outer protrusion 53b.

As shown in FIG. 8, the first clamping parts 52a ₁ , 52b ₁ , 53a ₁ , 53b ₁ are formed apart from the surface of the main body part 51, whereas the first clamping parts 52a ₂ , 52b ₂ , 53a ₂ and 53b ₂ are formed to extend from the surface of the main body portion 51, as shown in FIG. The first clamping parts 52a ₁ , 52b ₁ , 53a ₁ , 53b ₁ and the first clamping parts 52a ₂ , 52b ₂ , 53a ₂ , 53b ₂ are all triangular prism-shaped, and the width decreases toward the tip and becomes sharp. There is.

The distance between the first clamping part 52a ₁ and the first clamping part 52b ₁ and the distance between the first clamping part 53a ₁ and the first clamping part 53b ₁ are set to be less than or equal to the diameter of the string member 6. be done. For example, the distance between the tip of the first clamping part 52a ₁ and the tip of the first clamping part 52b ₁ , and the distance between the tip of the first clamping part 53a ₁ and the tip of the first clamping part 53b ₁ are , is set to be equal to or less than the diameter of the string-like member 6.

Similarly, the distance between the first clamping part 52a ₂ and the first clamping part 53a ₂ and the distance between the first clamping part 52b ₂ and the first clamping part 53b ₂ are the diameter of the string member 6. It is set as below. For example, the distance between the tip of the first clamping part 52a ₂ and the tip of the first clamping part 53a ₂ , and the distance between the tip of the first clamping part 52b ₂ and the tip of the first clamping part 53b ₂ are , is set to be less than or equal to the diameter of the string-like member 6.

Further, as shown in FIG. 5, on the side surface of the first outer protrusion 53a, the string-like member 6 is attached to the first outer protrusion 53a at a portion that does not face the first outer protrusion 52a and the second outer protrusion 53b. A recess 53ac into which the string-like member 6 fits when it is wound is formed on the side surface of the recess 53a- _c . Therefore, since the upper end of the first outer protrusion 53a is arranged above the string member 6 wound around the side surface of the first outer protrusion 53a, the string member 6 is prevented from coming off upward. can.

Similarly, as shown in FIG. 6, on the side surface of the second outer protrusion 52b, the string-like member 6 is attached to the second outer protrusion in a portion that does not face the first outer protrusion 52a and the second outer protrusion 53b. _A recess 52bc is formed in the side surface of 52b, into which the string-like member 6 is fitted when it is wound. Therefore, since the upper end of the second outer protrusion 52b is arranged above the string member 6 wound around the side surface of the second outer protrusion 52b, the string member 6 is prevented from coming off upward. can.

The inner protrusion 54 protrudes from the surface of the main body 51 and is disposed between the protrusions 52 and 53. That is, the inner protrusion 54 is arranged inside the first outer protrusion 52a, the second outer protrusion 52b, the first outer protrusion 53a, and the second outer protrusion 53b.

The inner protrusion 54 is arranged at the center of the first outer protrusion 52a, the second outer protrusion 52b, the first outer protrusion 53a, and the second outer protrusion 53b. That is, the inner protrusion 54 is arranged at a position equidistant from the first outer protrusion 52a, the second outer protrusion 52b, the first outer protrusion 53a, and the second outer protrusion 53b.

The first outer protrusion 52a, the second outer protrusion 52b, the first outer protrusion 53a, and the second outer protrusion 53b are arranged at equal intervals in the circumferential direction around the inner protrusion 54. That is, the first outer protrusion 52a, the second outer protrusion 52b, the first outer protrusion 53a, and the second outer protrusion 53b are arranged at intervals of 90 degrees around the inner protrusion 54. Gaps through which the string-like member passes are formed between the inner protrusion 54 and the first outer protrusion 52a, second outer protrusion 52b, first outer protrusion 53a, and second outer protrusion 53b. Ru.

The height of the inner protrusion 54 is higher than the height of the first outer protrusion 52a, the second outer protrusion 52b, the first outer protrusion 53a, and the second outer protrusion 53b. The cross-sectional area of the inner protrusion 54 is smaller than the cross-sectional areas of the first outer protrusion 52a, the second outer protrusion 52b, the first outer protrusion 53a, and the second outer protrusion 53b. That is, the inner protrusion 54 is formed thinner than the first outer protrusion 52a, the second outer protrusion 52b, the first outer protrusion 53a, and the second outer protrusion 53b.

On the side surface of the inner protruding part 54, eight second holding parts _54a1 protruding outward are formed at approximately equal intervals. The eight second clamping parts 54a ₁ are the four second clamping parts 54a that respectively protrude toward the first outer protrusion 52a, the second outer protrusion 52b, the first outer protrusion 53a, and the second outer protrusion 53b. Contains ₁ . The second holding portion _54a1 is formed to extend from the surface of the main body portion 51. The second holding portions 54a ₁ each have a triangular prism shape, and the width decreases toward the tip and becomes sharp.

The fitting attachment part 55 is a member that fits into the holes 33a' and 33b' formed in the horizontal frames 33a and 33b of the tent 1 to attach the string fixing device 50 to the horizontal frames 33a and 33b. The horizontal frames 33a, 33b are cylindrical members, and the holes 33a', 33b' of the horizontal frames 33a, 33b have an elliptical shape. The longitudinal direction of the holes 33a', 33b' is parallel to the longitudinal direction of the horizontal frames 33a, 33b.

As shown in FIG. 9, the fitting attachment portion 55 has an elliptical shape that is approximately the same shape as the holes 33a' and 33b' of the horizontal frames 33a and 33b, and its long axis direction is parallel to that of the main body portion 51. It is parallel to the long side direction. As shown in FIG. 7, a stepped portion 55a is formed near the root of the fitting attachment portion 55, and the portion closer to the root than the stepped portion 55a has a smaller diameter than the portion closer to the tip than the stepped portion 55a. . The diameter of the part closer to the base than the step 55a is approximately the same as the diameter of the holes 33a', 33b' of the horizontal frames 33a, 33b, and the diameter of the part closer to the tip of the horizontal frame 33a, 33b is the same as the diameter of the part closer to the tip than the step 55a. It is larger than the diameter of the holes 33a' and 33b'. The length of the portion closer to the base than the stepped portion 55a is approximately the same as the thickness of the horizontal frames 33a, 33b to which the string fixture 50 is attached.

The fitting attachment portion 55 has a through hole 55b extending in the long side direction of the main body portion 51, as shown in FIG. The through hole 55b has a substantially rectangular cross-sectional shape, and is formed from a portion closer to the root portion than the step portion 55a to a portion closer to the tip end side of the step portion 55a. Therefore, when the fitting attachment part 55 is inserted into the holes 33a' and 33b' of the horizontal frames 33a and 33b, the fitting attachment part 55 is deformed and the through hole 55b is reduced. has a smaller diameter and is disposed inside the horizontal frames 33a, 33b.

Thereafter, the diameter of the portion closer to the distal end than the stepped portion 55a returns inside the horizontal frames 33a, 33b, and becomes larger than the diameter of the holes 33a', 33b' of the horizontal frames 33a, 33b. Therefore, the fitting attachment portion 55 will not come off from the holes 33a', 33b' of the horizontal frames 33a, 33b. At this time, since the portion closer to the base than the stepped portion 55a is approximately the same as the diameter of the holes 33a', 33b' of the horizontal frames 33a, 33b, it fits into the holes 33a', 33b' of the horizontal frames 33a, 33b. match. Therefore, the string fixture 50 is attached to the outer peripheral surfaces of the horizontal frames 33a, 33b.

Regarding the method of stretching the string member 6 to the roof part 3 of the tent 1 using the string fixing devices 50 each fixed to the upper part of the four horizontal frames 33a arranged apart in the longitudinal direction of the tent 1, This will be explained based on FIG. Note that the method for stretching the string member 6 across the roof portion 3 of the tent 1 is also similar using the string fixing devices 50 fixed to the upper portions of the four horizontal frames 33b, respectively.

First, the string-like member 6 is attached to the string fixture 50 fixed to the upper part of the horizontal frame 33a that is disposed closest to the front among the four horizontal frames 33a. That is, as shown in FIG. 10(a), one end 6a of the string member 6 is inserted between the first outer protrusion 52a and the second outer protrusion 52b, and the outer circumference of the inner protrusion 54 is rotated clockwise. After winding it around, it is passed between the first outer protrusion 53a and the second outer protrusion 53b. As a result, one end 6a of the string member 6 is fixed to the string fixture 50.

At that time, the string-like member 6 passing between the first outer protruding part 52a and the second outer protruding part 52b is connected to the first holding part _52a1 of the first outer protruding part 52a and the first holding part 52a1 of the second outer protruding part 52b. The string-like member ₆ , which passes below the first clamping part 52b1 and between the first outer protrusion 53a and the second outer protrusion 53b, is attached to the first clamping part _53a1 of the first outer protrusion 53a. and passes below the first clamping part _53b1 of the second external protrusion 53b. This prevents the string-like member 6 from coming off between the first outer protrusion 52a and the second outer protrusion 52b and between the first outer protrusion 53a and the second outer protrusion 53b.

Further, the string-like member 6 wound around the outer circumference of the inner protrusion 54 is pressed toward the first clamping part _54a1 of the inner protrusion 54, and the string-like member 6 extends in the circumferential direction of the inner protrusion 54. Prevented from moving.

Subsequently, the string-like member 6 is attached to the string fixture 50 fixed to the upper part of the horizontal frame 33a adjacent to the back side of the horizontal frame 33a disposed closest to the front side. That is, as shown in FIG. 10(b), after fixing one end of the string-like member 6 to the horizontal frame 33a disposed closest to the front side, the string-like member 6 is stretched to the back side while being stretched with an appropriate tension. It is fixed to a string fixture 50 fixed to the upper part of the adjacent horizontal frame 33a. After inserting the string-like member 6 between the first outer protrusion 52a and the second outer protrusion 52b and along a part of the outer circumference of the inner protrusion 54, the first outer protrusion 53a and the second outer protrusion 53a are inserted. and the protrusion 53b. Thereby, the middle portion of the string-like member 6 is fixed to the string fixture 50.

At that time, in the same way as described above, the string member 6 is inserted between the first outer protrusion 52a and the second outer protrusion 52b and between the first outer protrusion 53a and the second outer protrusion 53b. This prevents the string member 6 from coming off, and also prevents the string member 6 from moving in the circumferential direction of the inner protrusion 54.

Subsequently, the string-like member 6 is attached to the string fixture 50 fixed to the upper part of the horizontal frame 33a adjacent to the back side. The method is similar to the method described in FIG. 10(b).

Thereafter, the string-like member 6 is attached to a string fixing device 50 fixed to the upper part of the horizontal frame 33a disposed on the rearmost side. That is, as shown in FIG. 10(c), the string-like member 6 is inserted between the first outer protrusion 52a and the second outer protrusion 52b, and the outer circumference of the inner protrusion 54 is wound clockwise. After that, it is passed between the first outer protrusion 53a and the second outer protrusion 53b. Thereby, the other end 6b of the string member 6 is fixed to the string fixture 50.

At that time, in the same way as described above, the string member 6 is inserted between the first outer protrusion 52a and the second outer protrusion 52b and between the first outer protrusion 53a and the second outer protrusion 53b. This prevents the string member 6 from coming off, and also prevents the string member 6 from moving in the circumferential direction of the inner protrusion 54.

As described above, the string fixing device 50 of the present embodiment includes a main body 51 and two protrusions 52 and 53 that protrude from the surface 51 of the main body and are arranged to face each other. A gap is formed between 52 and 53 through which the string-like member 6 passes, and on the side surfaces of the two protrusions 52 and 53 are first clamping parts 52a ₂ and 52b ₂ that protrude toward the other protrusion. , 53a ₂ , 53b ₂ are formed.

(Second embodiment)
The difference between the indoor tent 301 of this embodiment and the indoor tent 1 of the first embodiment is that the indoor tent 1 has a substantially rectangular shape in plan view, whereas the indoor tent 301 has a substantially rectangular shape in plan view. This point is approximately octagonal in shape.

As shown in FIG. 11, the indoor tent 301 has a substantially octagonal shape in plan view, and an entrance portion P is formed on the side surface thereof. Hereinafter, the description will be made assuming that the side surface of the tent 1 where the entrance portion P is formed is the front side.

As shown in FIG. 12, a frame structure 302 that forms the framework of the tent 301 includes eight vertical supports 310, a lower frame portion 320 located at the bottom of the tent 301, and a frame structure 302 located above the eight vertical supports 310. 3, and an upper frame portion 331 disposed above the frame portion 330.

The eight vertical struts 310 include two vertical struts 310a arranged on both sides of the entrance part P and six vertical struts 310b arranged at equal intervals between the two vertical struts 310a. There is. The eight vertical columns 310 are arranged so that their upper ends are inclined closer to the center of the tent than their lower ends. The eight vertical supports 310 all have substantially the same length, and their upper ends are arranged on the same horizontal plane.

The lower frame portion 320 connects the lower portions of the eight vertical columns 310 and has a substantially octagonal shape that is the same as the planar shape of the tent 301. Note that the lower frame 320 is not disposed between the two vertical supports 310a disposed on both sides of the entrance portion P.

The frame portion 330 connects the upper ends of the adjacent vertical columns 310, and has a substantially octagonal shape that is the same as the planar shape of the tent 301. As described above, since the upper ends of the eight vertical columns 310 are arranged on the same horizontal plane, the frame-shaped portion 330 is arranged substantially parallel to the horizontal plane.

The upper frame portion 331 has eight horizontal frames 332. The eight horizontal frames 332 extend from the corners of the substantially octagonal planar shape toward the central portion 335 of the tent 1. Each of the eight horizontal frames 332 has a curved portion 332a ₁ that extends upward from the frame-shaped portion 330 and then curves in the horizontal direction. In the horizontal frame 332, a portion closer to the center portion 335 of the tent 301 than the curved portion _332a1 is substantially linear, and is inclined so as to be disposed upward as it approaches the center portion 335 of the tent 301.

The indoor tent 301 has a roof portion 303 placed on the top of the tent 301 and a sheet member 312 attached to the side surface of the tent 301.

The roof portion 303 includes a frame portion 330 and a plurality of horizontal frames 332 included in the frame structure 302, an annular sheet 305, and a plurality of short sheets 306a.

The annular sheet 305 is stretched over the entire circumference of the tent 301 along the frame portion 330. The annular sheet 305 is integrally formed in a continuous annular shape, and has a substantially octagonal opening 305a.

The annular sheets 305 are arranged on each of the eight sides of the tent 301 so as to extend upward from the outer periphery of the frame portion 330 and cover the curved portion 332a ₁ of the horizontal frame 332.

The plurality of short sheets 306a have a rectangular shape with a predetermined width, and are arranged at the top of the tent 301 along the side surfaces of the tent 301 while being spaced apart from each other. Specifically, two short sheets 306a are arranged parallel to each other between two adjacent horizontal frames 332, respectively. The short sheet 306a is suspended from a string member 306 stretched between two adjacent horizontal frames 332. The surface of the short sheet 306a is arranged parallel to the vertical direction while suspended from a string-like member.

On the side surface of the frame structure 302, as shown in FIG. 12, a side surface gap 311 is formed between adjacent vertical columns 310, but in the indoor tent 301, as shown in FIG. A side sheet 312 covering 311 is attached.
