Description

Technical Field

[0001] The present invention relates to a foldable sauna tent and a sauna using the same.

Background Art

[0002] Enjoying saunas has become established, and with the recent rise of the outdoors, there is a demand to experience a sauna in the open nature to refresh both the mind and body. The sauna tent of Patent Document 1 can be set up in such nature and is a tent that can be carried and assembled. Specifically, the tent of Patent Document 1 consists of a top surface and four side surfaces for forming a closed space heated by an electric heater, and these top surface and four side surfaces are connected to each other. Each of the total five surfaces of these top surface and side surfaces is maintained in a framework by four frames and has a structure that can be opened and closed like an umbrella.

[0003] Also, the tent of Patent Document 1 is divided into an outer tent and an inner tent, and the inner tent is attached to the inside of the outer tent with a connecting tool. At this time, a gap serving as a heat-insulating layer is attached between the inner tent and the outer tent. Thus, even a generally portable electric heater without power is trying to raise the temperature inside the closed space to a temperature suitable for a sauna. In this way, in the sauna tent of Patent Document 1, the top surface and the four side surfaces are folded like an umbrella for carrying, and at the sauna setup location, the top surface and the four side surfaces are opened like an umbrella to expand the outer tent, and the inner tent is attached to the outer tent to complete the sauna tent.

Patent Document 1

Summary of the Invention

[0005] However, the sauna tent described in Patent Document 1 requires opening and extending the top and all four sides of the outer tent, and then attaching the inner tent while considering the position of the entrance and other factors. Therefore, although the setup time is shorter than other general tents that use joined frames, it still requires a considerable amount of time and effort. This time and effort is due to the unique characteristic of saunas, which is to raise the temperature inside the tent. This invention has been made in view of the above circumstances, and aims to provide a sauna tent that is easy to assemble, even though it has heating characteristics suitable for a sauna, and a sauna that utilizes the same. [Means for solving the problem]

[0006] The above problem is solved by a sauna tent comprising a tent section having a canopy and side walls that surround a sauna stove when extended, and a foldable frame connected to the tent section to maintain the framework, wherein the tent section has a canopy that is detachable from the frame and side walls that are detachable from the canopy, and the frame has a plurality of upright support frames and a plurality of canopy frames that support the canopy from below, and each of the plurality of canopy frames has one end that is rotatably connected in the vertical direction to the upper end of the support frame and the other end that is rotatably connected in the vertical direction to a hub The hub has a stopper that prevents the other end from rotating further when it is above the upper end of the support frame, and the canopy frame is made of an elastic material that exhibits elastic force, which does not exhibit elastic force in the folded state, but in the extended state the other end is positioned above the upper end of the support frame while exhibiting elastic force, and the canopy has a gripping part on the upper surface opposite to the canopy frame in the extended state for pulling the other end upward against the elastic force when extending it, the canopy is solved by a sauna tent.

[0007] The sauna tent according to the present invention has a tent section with a canopy and side walls that surround a sauna stove when extended, and a foldable frame connected to this tent section to maintain the framework. Therefore, the stove can be enclosed in a closed sauna space to raise the temperature inside the tent, and it can also be folded and carried. Furthermore, in this invention, the canopy and side walls are detachable, allowing for easier assembly by separating them to reduce weight. Consequently, the increased ease of assembly allows for, for example, increasing the thickness of the canopy and side walls or increasing the amount of insulation material, enabling a suitable temperature rise for a sauna. Each of the multiple tent frames that support the tent is connected at one end to the upper end of the support frame so as to be able to rotate vertically, and at the other end to the hub so as to be able to rotate vertically. Therefore, the tent frame can be extended by lifting the other end, and conversely folded by lowering the other end. Here, the hub has a stopper that prevents the other end of the tent frame from rotating further when it is above the upper end of the support frame (for example, at the top of the tent). The tent frame is made of an elastic material and, when extended, exerts elastic force so that the other end is positioned above the upper end of the support frame. Then, if the other end is lifted and positioned above the upper end of the support frame, the tent frame exerts elastic force until it can no longer move upwards. As a result, the tent frame is curved, for example, so as to be convex upwards, and force is applied to both ends to maintain the frame shape and firmly support the tent. Furthermore, the user can pop up and extend the tent frame in one action by simply lifting the other end of multiple tent frames, or the hub to which they are connected, using the elastic force. However, if one tries to lift the other end from below to extend the tent frame against its elastic force, the frame will suddenly change shape due to its elasticity, causing it to whip against the hand and potentially cause injury. However, the tent of this invention has a gripping part on its upper surface when extended, which allows the other end to be pulled upward against its elastic force. Therefore, it is possible to avoid the tent frame whipping against the hand and to assemble it easily.

[0008] Preferably, the side panels have an air intake for taking in combustion air necessary for the gas that serves as the fuel source for the stove, the canopy has an exhaust port for releasing the exhaust from the stove to the outside, and positioning marks are provided for connecting the side panels and the canopy so that the air intake and the exhaust port are in a predetermined positional relationship. In this regard, while using gas as fuel for a stove makes it easier to increase the heat output and raise the temperature inside the tent compared to using electricity, using gas requires an air intake for combustion air and an exhaust vent through which a chimney or similar can pass to vent the exhaust to the outside. In this preferred invention, an air intake is provided in the side wall and an exhaust vent in the canopy in order to effectively draw in and exhaust air. Furthermore, the air intake in the side wall and the exhaust vent in the canopy must be in a predetermined positional relationship. However, when connecting the detachable canopy and side wall, there is a risk that the positions of the air intake and exhaust vents may become misaligned. Therefore, in this preferred invention, positioning marks are provided for connecting the side wall and canopy so that the positions of the air intake and exhaust vents are in a predetermined positional relationship. Thus, by connecting the side wall and canopy so that the positions of the air intake and exhaust vents do not become misaligned, problem-free combustion of the stove is possible.

[0009] Preferably, the canopy has a canopy connecting means that is detachably connected to the canopy frame, and the canopy connecting means is formed from an insulating member that covers the canopy frame in a long cylindrical shape along the longitudinal direction of the canopy frame. According to the above configuration, the tent canopy is connected to the tent frame by a tent connecting means, ensuring secure support without displacement. Furthermore, since this tent connecting means is formed from an insulating material that covers the tent frame in a long cylindrical shape, it prevents the user from being burned by touching the heated tent frame inside the tent. Moreover, because the tent connecting means is long and cylindrical, even if the tent frame springs up due to its elasticity when lifted with the gripping part, the risk of the tent connecting means being damaged is reduced.

[0010] Preferably, the side curtain is positioned outside the support frame and has a connecting means for the side curtain that is detachably connected to the support frame, and the connecting means for the side curtain is formed from an insulating member that covers the support frame in a long cylindrical shape along the longitudinal direction of the support frame. According to the above configuration, the side panels are connected to the support frame by a side panel connecting mechanism, preventing them from shifting position due to wind or other factors. Furthermore, since this side panel connecting mechanism is formed from an insulating material that covers the support frame in a long, cylindrical shape, it prevents the risk of the user being burned by touching the heated support frame inside the tent.

[0011] Preferably, the side curtain has a slit separate from the entrance / exit, which is long enough for a user to enter and exit, and the slit can be opened and closed with a magnet. With the above configuration, the slit can be opened and closed with a magnet, making it easy to widen. Therefore, even if the user's condition inside the tent deteriorates, they can easily get out. In particular, if gas is used as the combustion source for the stove, there is a non-zero possibility that the user may suffer carbon monoxide poisoning due to incomplete combustion, and in such a case, emergency escape is possible.

[0012] Preferably, the canopy and the side panels have detachable slide fasteners for attaching and detaching them from each other, the side panels have entrance slide fasteners for opening and closing entrances, and the fasteners for the detachable slide fasteners and the fasteners for the entrance slide fasteners are arranged adjacent to each other and covered by the same cover member. With the above configuration, heat can be easily prevented from escaping by concentrating the fasteners of the slide zippers, which allow heat to escape easily from inside the tent, and covering them with a single cover component.

[0013] Preferably, the detachable slide fastener has a left-handed fastener in which the slider slides counterclockwise and a right-handed fastener in which the slider slides clockwise, and the closed end of the left-handed fastener and the closed end of the right-handed fastener overlap so that one of them hides the other. According to the above configuration, it is possible to prevent heat from escaping from inside the tent through the ends of the slider teeth (elements).

[0014] Preferably, the side curtain has an excess portion that extends below the erected support frame, and the excess portion is characterized by having an outer excess portion that can be folded outwards and an inner excess portion that can be folded inwards. According to the above configuration, outside air can be effectively prevented from entering through the outer and inner excess sections, and conversely, hot air can be prevented from escaping from inside the tent, thereby improving airtightness.

[0015] Furthermore, the problem is solved by a sauna comprising a cartridge-type gas cylinder containing liquefied gas, a stove using the liquefied gas as a fuel source, and a tent surrounding the stove in an extended state, wherein the tent has a tent section having a canopy and side walls, and a foldable frame connected to the tent section for maintaining the framework, the tent section having a canopy that is detachable from the frame and side walls that are detachable from the canopy, the frame having a plurality of erected support frames and a plurality of canopy frames that support the canopy from below, and each of the plurality of canopy frames has one end that is rotatably connected in the vertical direction to the upper end of the support frame, and other One end is connected to a hub so as to be rotatable in the vertical direction, and the hub has a stopper that prevents the other end from rotating further when it is above the upper end of the support frame. Furthermore, the tent frame is formed of an elastic body that exhibits elastic force, and while it does not exhibit the elastic force in the folded state, in the extended state it exhibits the elastic force while the other end is positioned above the upper end of the support frame. The tent is provided with a sauna that has a gripping part on the upper surface opposite to the tent frame in the extended state for pulling the other end upward against the elastic force when transitioning from the folded state to the extended state.

[0016] The sauna according to the present invention has the above-described configuration of a sauna tent, and as already explained, the stove can be enclosed in a closed space to raise the temperature inside the tent, and it can also be folded and carried. Furthermore, by pulling up the handle provided on the top surface of the tent against the elastic force of the tent frame, the tent frame can be easily popped up and unfolded without injury, and the shape of the tent frame can be maintained by its elastic force. Moreover, since the present invention uses gas as the fuel source for the stove, it is possible to raise the temperature to a level suitable for a sauna by increasing the heat output compared to electricity. In addition, since this gas is contained in a cartridge-type gas cylinder, it is highly portable and easy to handle. [Effects of the Invention]

[0017] According to the present invention, it is possible to provide a sauna tent having a temperature rising characteristic suitable for a sauna, which is easy to assemble, and a sauna using the same.

Embodiments for Carrying Out the Invention

[0019] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The embodiments described below are preferred examples of the present invention and are subject to various technically preferred limitations. However, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description. In addition, similar components are denoted by the same reference numerals in the drawings, and detailed descriptions are omitted as appropriate.

[0020] [Overview of Saunas] Figure 1 is a perspective view of the sauna 10 using a sauna tent 15, and Figure 2 is a perspective view of the frame 17 in the extended state of the sauna tent 15. The overview of the sauna 20 will be mainly explained using these figures. Sauna 10 has a stove 30 and a tent 15. First, let me explain about the Stove 30. The stove 30 is a combustion device for raising the temperature inside the tent 15 to a temperature suitable for a sauna, and uses gas as fuel, for example. Liquefied petroleum gas (LP gas / LPG) such as butane, isobutane, or propane can be used as the gas, and in this embodiment, liquefied butane compressed and stored in a portable cartridge-type cylinder 32 is used as the fuel source. For example, "Iwatani Cassette Gas" (trademark) can be used as this cylinder 32. In the figure, multiple cartridge-type cylinders 32 located outside the tent 15 are connected by a gas pipe 34, and gas is supplied from this gas pipe 34 to the burner 35 inside the stove 30. Multiple cartridge-type cylinders 32 are used to ensure that even if the gas supply is increased, the fuel will not run out immediately, in order to suitably achieve the desired temperature rise in the sauna.

[0021] Inside the stove 30, a heat storage material 36 is placed above the burner 35 to store the heat from the flame generated by the burner 35, and sauna stones 37 are also placed on the heated top surface of the stove 30. These heat storage material 36 and sauna stones 37 create temperature characteristics suitable for a sauna, and steam can be generated by pouring water on the sauna stones 37. In this embodiment, when the gas consumption was set to 4,060 kcal / h and the tent 15 described later was used, the temperature inside the tent 15 could be raised to approximately 65 to 80 degrees Celsius (depending on the measurement location inside the tent) when the outside temperature was 25 to 27 degrees Celsius (in the shade).

[0022] In the case of a gas-fueled stove 30, air is needed to burn the flame, and therefore the tent 15 has an air intake 22, which is a hole for taking in air. The tip of the air intake pipe 38, which is spatially connected to the burner 35 of the stove 30, can be exposed to the outside through the air intake 22. The air intake 22 also serves to heat outside air with the stove 30 before sending it into the tent, and to bring the gas pipe 34 from the cartridge-type cylinder 32 located outside the tent into the tent. For these reasons, the air intake 22 is located close to the stove 30. Furthermore, the sauna 10 needs to release exhaust gases from the stove 30 to the outside. This release is achieved by exposing the tip of the chimney 39 connected to the stove 30 to the outside space. For this reason, the tent 15 has an exhaust port 24 through which the chimney 39 can be inserted, and this exhaust port 24 is positioned above the stove 30 to effectively exhaust the gases.

[0023] Next, I will explain tent 15. The tent 15 is intended to create a closed space for a sauna within the interior space S, and is preferably installed on an insulating mat (not shown). The tent 15 shown in the figure is 150 cm wide, 150 cm deep, and 180 cm high at its highest point and 160 cm high at its lowest point. This tent 15 has a flexible "cover section 16" and a "frame 17" that connects to the cover section 16 to form the framework of the tent 15.

[0024] The tent section 16 surrounds the stove 30 and is designed to create a sauna-like temperature inside the tent 15. Preferably, the entire section is made of the same material and has both thermal insulation and waterproofing properties. For example, the tent section 16 has a three-layer structure. The inner layer is a waterproof and thermally insulating sheet with a urethane resin coating on the fabric surface, and the thermal insulation effect is enhanced by using a silver coating. The outer layer is a sheet with a water-repellent finish, which speeds up the drying time for any rain or water that adheres to it. The middle layer uses an insulating material such as synthetic cotton to enhance thermal insulation. These layers are not sewn together but are partially heat-sealed (for example, in a grid pattern) in the thickness direction to create a unified structure. The tent section 16, made of such materials, has a "canopy 50" and "side curtains 52". The canopy 50 is preferably a roof with a top 50A that allows rainwater to flow easily, but in the case of the figure, it is also a cover that covers the beam frame 23 located between the upper ends 80A, 80A of the multiple support frames 80, 80, which will be described later. The canopy 50 also has a transparent or translucent skylight 27, allowing you to experience the feeling of being in nature.

[0025] The side panels 52 are walls that surround the stove 30 on all four sides. In this embodiment, the side panels 52 have four sides and are square in shape, but the present invention is not limited to this, and may be other regular polygons or even cylindrical. The side curtain 52 is a single curtain body and is detachably connected to the lower end 50C of the canopy 50, and is also wrapped around the four support frame 80, which will be described later. The means of connecting the canopy 50 and the side curtain 52 in this embodiment is a slide fastener (hereinafter referred to as "detachable slide fastener") 90. When the side curtain 52 is wrapped around the four support frame 80, the space between both ends 52A and 52B becomes an entrance / exit 48. The entrance / exit 48 can be opened and closed with a slide fastener (hereinafter referred to as "entrance / exit slide fastener") 14. Additionally, the side panels 52 are also equipped with transparent or translucent windows 28.

[0026] The frame 17 has multiple upright "support frame 80", "beam frame 23" interposed between these support frame 80 to form beams, and multiple "canopy frame 60" that support the canopy 50 from below.

[0027] The support frame 80 is the leg portion and is made of metal, having higher rigidity than the other frames 23 and 60. In this embodiment, there are four of them, but there may be three or five or more. This support frame 80 is extendable and retractable. Known techniques can be used to adjust the length; for example, as shown in Figure 2, a thin pole 80C can be inserted into the inner space of a thick pole 80B, and these can be pinned at any of several points along the length.

[0028] As shown in Figure 2, the beam frame 23 is arranged along the horizontal direction (when the tent is installed without tilting, the same applies hereafter) and supports the loads from the canopy frame 60 to which the canopy 50 is connected and the support frame 80 to which the side walls 52 are connected. This beam frame 23 is also made of metal and is made expandable and contractible in the horizontal direction using known technology, and is structured so that multiple support frames 80 can move closer to and further apart from each other. For example, the beam frame 23 in the figure is made of multiple X-shaped frames 23A and 23B connected by an axis (joint) 29 in the center, which are connected along the horizontal direction to form a magic hand structure (also called a scissor structure). This allows the angle θ1 between two frames 23A and 23B to be increased and folded, and reduced and extended.

[0029] The support frame 80 has an upper connecting portion 42 and a lower connecting portion 43 that are connected to the frames 23A and 23B of the beam frame 23 so that they can rotate. Figure 3 is an enlarged view of the area around the lower connecting portion 43. The end portion 23A of the beam frame 23 is supported by the shaft portion 26 and is rotatable around its axis (in the direction of arrow R1) (the upper connecting portion 42 in Figure 2 has a similar axial structure). The lower connecting portion 43 is slidable along the longitudinal direction (vertical direction) Y of the support frame 80 and is also called a slider. As a result, the beam frame 23 shown in Figure 2 does not protrude from the upper end portion 80A of the support frame 80 even when folded, and the frame 17 can be folded compactly. Note that the beam frame 23 of the present invention is not limited to a magic hand structure, and other link mechanisms may be used.

[0030] The tent frame 60 shown in Figures 1 and 2 is rod-shaped overall and supports the tent 50 from below, maintaining the desired shape of the tent 50. One end 62 of this tent frame 60 is rotatably connected vertically to the upper end 80A of the support frame 80. Specifically, the upper end 80A of the support frame 80 has the upper connecting part 42 described above, and this upper connecting part 42 is rotatably connected not only to the beam frame 23 but also to the tent frame 60. Figure 4 is an enlarged view of the area surrounding the upper connecting portion 42. The upper connecting portion 42 in Figure 4 has a pair of opposing plate-like members 53 and 54, and one end of the tent frame 60 (the connecting member into which one end is inserted) 62 is sandwiched between these plate-like members 53 and 54. The one end 62 is supported by a shaft portion 56 that passes between the pair of plate-like members 53 and 54, and is rotatable around that shaft (in the direction of arrow R2).

[0031] In contrast, the other end 64 of the tent frame 60 shown in Figure 2 is connected to the hub 65 so as to be rotatable in the vertical direction. The hub 65 is a member to which multiple other ends 64 of multiple tent frames 60 come together and are connected, and is located directly below the top 50A of the tent 50 in Figure 1. Figure 5 is an enlarged view of the hub 65, which has a main body 66 with multiple protrusions 21 in a plan view. There are four protrusions 21 in the figure, corresponding to the number of tent frames 60, and they are arranged at 90-degree intervals in a plan view, and the main body 66 is roughly cross-shaped in a plan view. The hub 65 has a main body 66 with protrusions 21 and a cylindrical body 18 that is rotatably connected to the main body 66 in the vertical direction. Specifically, the cylindrical body 18 is connected to the protrusions 21 by an axis 25 and is rotatable around its axis (direction R3 in the figure). The other end 64 of the tent frame 60 is inserted into and fixed inside the cylindrical body 18. As a result, the other end 64 is rotatably connected to the main body 66 of the hub 65 via the cylindrical body 18.

[0032] With the above configuration, when the hub 65 in Figure 2 and the other end 64 of the canopy frame 60 connected to it reach a predetermined position above the upper end 80A of the support frame 80, the canopy frame 60 expands, the beam frame 23 extends, and the distance between the support frames 80 increases, so that the tent is in its extended state. Conversely, when the hub 65 and the other end 64 connected to it lower, the canopy frame 60 closes, the beam frame 23 contracts, and the support frames 80 move closer together, so that the tent is in its folded state for transport and storage.

[0033] Furthermore, this embodiment has the following configuration. [Regarding the tent frame] The tent frame 60 shown in Figure 2 is made of an elastic material (for example, fiber-reinforced plastic such as glass fiber reinforced plastic or carbon fiber reinforced plastic) that exhibits elastic force when bent. Therefore, when the tent frame 60 is folded and extended without stress (without exhibiting elastic force), raising the hub 65 and the other end 64 connected to it causes the tent frame 60 to bend upward so that it is convex. The strain generated by this stress acts on the upper connecting part 42 and the hub 65, and the curved state is maintained by elastic force while the upper connecting part 42 and the hub 65 remain stationary. Furthermore, the tent frame 60 returns to its original shape when the hub 65 is lowered and folded, relieving the stress caused by the bending. In this embodiment, the tent frame 60 exhibits elastic force except for the connection points with the hub 65 and the support frame 80 (i.e., one end 62 inserted into the connecting member in Figure 4, and the other end 64 inserted into the cylindrical body 18 in Figure 5). Therefore, even when the hub 65 is lifted with the heavy tent 50 in Figure 1 connected to the tent frame 60, the tent frame 60 will spring up without any problems, forming an upwardly convex curved shape.

[0034] [About the hub] The hub 65 shown in Figure 5 has a stopper 41 that restricts the vertical rotation of the other end 64 of the tent frame 60 when the hub 65 reaches a predetermined position above the upper end 80A of the support frame 80 (see Figure 1), preventing the hub 65 from rotating any further upward. In this embodiment, the "predetermined upper position" refers to the position of approximately the top 50A of the tent when it is extended (see Figure 1). Specifically, as shown in Figure 5, the hub body 66 has a protruding portion 21 that contacts the cylindrical portion 18 into which the other end 64 of the elastic tent frame 60 is inserted when the cylindrical portion 18 reaches the predetermined position, and this contact portion acts as the stopper 41. In this embodiment, the stopper 41 is provided only on the hub 65, but a stopper to control rotation may also be provided on the upper connecting portion shown in Figure 4.

[0035] [Regarding the gripping part] As shown in Figures 4 and 5, the tent frame 60 has the elastic force described above, so the other end 64 and the hub 65 connecting them are raised upward against the elastic force to transition from the folded state to the extended state. However, just before transitioning to the extended state, the tent frame 60 springs up due to its strong elastic force, and this can cause injury if it hits the hand. Therefore, as shown in Figure 1, the tent 50 has a gripping part 84 on the upper surface 50B opposite to the tent frame 60 to pull the other end 64 (see Figure 5) and the hub 65 connecting them upward against the elastic force of the tent frame 60 when transitioning to the extended state. The gripping part 84 in Figure 1 is handle-shaped and four are arranged along each tent frame 60 (one is omitted in the figure). Also, the gripping part 84 is positioned closer to the hub 65 than the longitudinal center of the tent frame 60. As shown in Figure 7, which will be described later, the tent canopy 50 is connected to the tent frame 60 by a long, cylindrical tent connecting means 83 that runs along the longitudinal direction. Therefore, the gripping part 84 in Figure 1 is positioned along the tent connecting means 83 in Figure 7. This makes it easier for the gripping part 84 to transmit the force to pull the tent frame 60 upward via the tent connecting means 83.

[0036] [Regarding air intake and exhaust vents] As shown in Figure 1, the side wall 52 has an air intake 22 adjacent to the stove 30, and the canopy 50 has an exhaust vent 24 above the stove 30. Figure 6 is a view of the air intake 22 and exhaust vent 24 from inside the tent. The air intake and exhaust vents 22 and 24 will be explained using Figure 6 and Figure 1. The air intake 22 is a hole that penetrates the side wall 52. In the figure, the air intake 72 is rectangular, but it may be made circular, for example, to match the shape of the air intake pipe 38 inserted through it in Figure 1, thereby reducing the inflow of outside air. The side wall 52 also has a cover 71 that opens and closes the air intake 22. The cover 71 is made of the same material as the side wall 52 and is made larger than the air intake 22.

[0037] In Figure 6, viewed from the inside, the exhaust port 24 is a circular hole that matches the shape of the stove's chimney, while in Figure 1, viewed from the outside, it is a cylindrical body 24A, into which the chimney is continuously inserted. The inner diameter of the cylindrical body 24A in Figure 1 is approximately the same as the diameter of the chimney 39, thereby preventing heated air inside the tent from escaping through the canopy 50 and preventing exhaust gas from flowing into the tent. As shown in Figure 6, the exhaust port 24 is closed by a cover 72 when not in use. The cover 72 is made of the same material as the tent canopy 50 and is larger than the circular opening of the exhaust port 24. Furthermore, the cover 72 is provided with a means (for example, a magnet or hook-and-loop fastener) on its edge 72A that allows it to be attached to or detached from the tent canopy 50.

[0038] [Regarding ventilation openings] As shown in Figure 6, a ventilation opening 79 is provided on the side of the side wall 52 where the air intake 22 is located. The ventilation opening 79 is a through-hole to prevent excessive humidity and oxygen deficiency inside the tent. This ventilation opening 79 is normally closed with a cover 80 to raise the temperature inside the tent. The cover 80 is openable and closable, for example, by providing hook-and-loop fasteners on the periphery 80A of the cover 80 excluding the lower end 80B, allowing it to be opened and closed using the lower end 80B as an axis.

[0039] [Regarding the connection means for the side banners] The side curtain 52 in Figure 6 has a side curtain connecting means 82. In Figure 6, for ease of understanding, the YM portion of the side curtain connecting means 82 is shown open. The side curtain connecting means 82 has the function of connecting the support frame 80 and the side curtain 52, and the function of preventing the user from directly touching the heated support frame 80. To perform these functions, the side curtain connecting means 82 is formed from an insulating member (in this embodiment, the same material as the side curtain 52) that covers the support frame 80 in a long cylindrical shape along the longitudinal direction of the support frame 80. The side curtain connecting mechanism 82 is detachable from the support frame 80. In the diagram, this detachable mechanism is a slide fastener 67. The slide fastener 67 is opened, the support frame 80 is covered, and then the slide fastener 67 is closed, allowing the support frame 80 to be inserted into the long cylindrical shape. This detachable mechanism may also be a hook-and-loop fastener or the like.

[0040] As shown in Figure 6, the canopy 50 is positioned outside the beam frame 23, but it also has a cover body 81 that covers the inside of the beam frame 23. The cover body 81 is intended to prevent users from touching the heated beam frame 23 and is made of the same material as the canopy 50.

[0041] [Regarding the surplus portion] As shown in the cross-section of the side wall 52 in Figure 6, the side wall 52 has an excess portion 47 that extends below the erected support frame 80. The excess portion 47 improves the airtightness of the tent 15. Specifically, the excess portion 47 has an outer excess portion 45 that can be folded outwards and an inner excess portion 46 that can be folded inwards. The inner excess portion 46 is formed so that multiple inner excess portions 46, 46 overlap at the corners inside the tent, and these overlapping portions of multiple inner excess portions 46, 46 are detachably connected by hook-and-loop fasteners 46A.

[0042] [Regarding tent connection methods] Figure 7 shows the tent connecting means 83 provided on the tent canopy 50 as seen from inside the tent, and for ease of understanding, the UM portion of the tent connecting means 83 is shown opened. As shown in Figure 7, the tent canopy 50 has a canopy connecting means 83 for connecting to the canopy frame 60. The canopy connecting means 83 prevents misalignment between the canopy 50 and the canopy frame 60. The canopy connecting means 83 is also an insulating member (made of the same material as the canopy 50 in the figure) that covers the canopy frame 60 in a long cylindrical shape along its longitudinal direction, preventing the user from being burned by touching the heated canopy frame 60. This canopy connecting means 83 is attached to the area of ​​the canopy frame 60 excluding both ends. Furthermore, the tent connecting means 83 is detachable from the tent frame 60. In the diagram, this detachable means is a slide fastener 87. The slide fastener 87 is opened to cover the tent frame 60, and then the slide fastener 87 is closed to insert the tent frame 60 into the long cylindrical shape. Note that this detachable means may also be a hook-and-loop fastener or the like.

[0043] [Regarding positioning markers] Figure 8 shows the adjacent area between the detachable slide fastener 90, which is a means of attaching and detaching the canopy 50 and the side walls 52, and the entrance slide fastener 14. As shown in Figure 8, the detachable slide fastener 90 has a left-handed fastener 95 and a right-handed fastener 96. The left-handed fastener 95 slides the slider 58 counterclockwise along the teeth 93 and has a bottom stopper (fastener) 91 which is the starting point for starting the closing operation. The right-handed fastener 96 slides the slider 55 clockwise along the teeth 94 and has a bottom stopper (fastener) 92 which is the starting point for starting the closing operation. These two bottom stops 91 and 92 are located above and adjacent to the entrance slide fastener 14.

[0044] If the connection points between the canopy 50 and the side walls 52 are misaligned, the positional relationship between the air intake 22 of the side wall 52 (see Figure 1) and the exhaust 24 of the canopy 50 (see Figure 1) will be misaligned, which may prevent the air intake pipe 38 and chimney 39 from being properly inserted into the air intake and exhaust ports 22 and 24. Increasing the opening area of ​​the air intake and exhaust ports 22 and 24 would eliminate this risk, but increasing the opening area would hinder the heating characteristics suitable for a sauna. Therefore, positioning markers 100, 101, 102, and 103 are provided to connect the canopy 50 and the side walls 52.

[0045] The positioning markers 100 and 101 in the diagram are for the counter-clockwise zipper 95, with the marker (tag in the diagram) 100 on the canopy 50 and the marker (tag in the diagram) 101 on the side wall 52 being adjacent to each other. Markers 100 and 101 have the same color and / or pattern. This allows one to recognize that the connection between the canopy 50 and the side wall 52 is inappropriate if the horizontal positions of markers 100 and 101 are misaligned. The same applies to the clockwise zipper 96, consisting of positioning markers (tag in the diagram) 102 on the canopy 50 and positioning markers (tags in the diagram) 103 on the side wall 52, which are adjacent to each other, and these markers 102 and 103 have the same color and / or pattern.

[0046] [Regarding the starting end of the zipper and the cover component] As shown in Figure 8, the fasteners (bottom fasteners) 91 and 92 of the detachable slide fastener 90 and the fastener (bottom fastener) 98 of the entrance slide fastener 14 are positioned adjacent to each other, and these metal fittings that affect the temperature inside the tent are covered by the same cover member 76. The cover member 76 is an insulating material and in this embodiment is made of the same material as the tent canopy 50. The lower end 76A of the cover member 76 is connected to the tent canopy 50, and Figure 8 shows the cover member 76 in the rolled-up state. If it is not rolled up, it will be at the position of the dashed line and will cover the fasteners 91, 92, and 98 simultaneously.

[0047] [Regarding the end of the zipper] Figure 9 shows the area near the ends of the left-handed zipper 95 and the right-handed zipper 96, as described above, on the side opposite to the entrance 48 in Figure 1. For ease of understanding, in Figure 9, the slider 55 is slid all the way in the closing direction, and the slider 58 is stopped just before it is fully closed. As shown in Figure 9, the closed end 110 of the left-handed zipper 95 and the closed end 105 of the right-handed zipper 96 overlap so that one hides the other. In the figure, when the slider 58 of the left-handed zipper 95 is slid all the way to the left, the end (top stop) 105 of the right-handed zipper 96 is hidden by the end 110 of the left-handed zipper 95. Note that the slider 58 of the left-handed zipper 95 is stopped by the tape 112 of the right-handed zipper 96, not by the top stop fitting. This prevents the fitting of the end (top stop) 105 from affecting the temperature inside the tent.

[0048] [Regarding emergency exits] Figure 10 shows a slit 120, which serves as an emergency exit, formed in the side panel 52. In this embodiment, the slit 120 is formed on the side opposite to the side with the air intake 22 adjacent to the stove 30 in Figure 1. Specifically, the slit 120 is long enough for a user to enter and exit, and magnets are embedded in both the left and right ends 121 and 122 of the slit 120. As a result, the left and right ends 121 and 122 attract each other and stay tightly closed, and when it is time to escape, the magnets allow it to open quickly for escape. In addition, in the figure, handles 130 are attached to both the left and right ends 121 and 122 to make it easier to widen the slit 120.

[0049] [How to use] Next, an example of using the sauna tent 15 according to this embodiment will be described with reference to Figures 1 to 12. Figure 11 shows the frame 17 in the process of being folded, and Figure 12 shows the frame 17 completely folded. Note that in Figure 11, a part of the beam frame 23 is omitted to avoid making the drawing too complex.

[0050] First, when the user folds and stores the tent, they open zipper 90 in Figure 1 and zipper 67 in Figure 6 to remove the side walls 52 from the support frame 80 and canopy 50 (Step 1). The canopy 50 should not be removed yet. Next, the support frame 80 is shortened to about shoulder length, and the area around the hub 65 on the canopy 50 is pressed down from above against the elastic force of the canopy frame 60 (step 2). As a result, the hub 65 and the other end 64 of the canopy frame 60 (see Figure 2) move downward, and the frame 17 opens up slightly more than in Figure 11 or in Figure 11. Next, open the zipper 87 of the tent connecting means 83 in Figure 7 and remove the tent 52 in Figure 1 (Step 3). Note that opening the zipper 87 may also be done in Step 1. Next, the multiple support frames 80 are brought closer together, and the frame 17 is completely closed as shown in Figure 12, making it suitable for transport and storage (Step 4).

[0051] When setting up the tent, the user first separates the multiple support frames 80 from the fully closed frame 17 shown in Figure 12, so that the frame 17 is in the state shown in Figure 11 or slightly more open than in Figure 11 (Step 1-1). It is preferable to keep the support frames 80 short in this step. Next, the canopy connecting means 83 shown in Figure 7 is attached to the canopy frame 60 with the fastener 87, and the canopy 50 is connected to the frame 17 (Step 2-1). Next, the gripping part (handle-shaped in the figure) 84 on the top surface of the tent 50 in Figure 1 is lifted, and the hub 65 and the other end 64 of the tent frame 60 connected to it (see Figure 2) are lifted above the upper end 80A of the support frame 80 (step 3-1). As a result, the multiple tent frames 60 spring up and spread out due to their elastic force, the multiple support frames 80 separate, and the beam frame 23 also extends, resulting in the extended state shown in Figure 2. In other words, the extended state can be created by popping it up in a single action. Next, the support frame 80, which will serve as the legs, is extended, and the side panels 52 are attached to the lower end 50C of the canopy 50 using the left-hand fasteners 95 and right-hand fasteners 96 shown in Figure 8, as shown in Figure 1 (Step 4-1). At this time, the horizontal positions of the markers 100 and 101, and the horizontal positions of the markers 102 and 103, which are of the same color and pattern, are attached so that they do not become misaligned. This allows the positions of the air intake 22 and exhaust 24 in Figure 1 to be set to the predetermined and appropriate positions. Next, as shown in Figure 6, the side wall connecting means 82 provided on the side wall 52 is attached to the support frame 80 with fasteners 67 (step 5-1) to complete the sauna tent.
