Description

[Technical Field]

[0001] The present invention relates to a stove set that is installed outdoors and used for keeping warm and cooking, and a method for installing the stove. [Background technology]

[0002] Recently, camping, mountain climbing, and fishing have become popular, and some people bring stoves to their campsites to keep warm and cook food.

[0003] For example, the portable outdoor wood stove described in Patent Document 1 includes a furnace body and a telescopic chimney assembly. The furnace body includes a furnace for burning firewood and a through-hole formed in the upper part of the furnace body and connected to the furnace. The telescopic chimney assembly includes a chimney base whose outer wall is connected to the inner peripheral surface of the through-hole, and a truncated cone-shaped telescopic chimney. The chimney is connected to the inner wall of the chimney base and is connected to the furnace.

[0004] The furnace body is usually mounted on the ground by multiple legs, and the chimney is usually attached so that it extends directly upward from the top of the furnace body, or so that it extends horizontally from the side of the furnace body and then bends at a right angle and extends upward.

[0005] The length of the chimney (for example, about 1550 mm) is several times the height of the furnace body and legs (for example, about 350 mm). In addition, the outdoor ground on which a wood stove or other stove is installed is often uneven.

[0006] Therefore, simply attaching a chimney to a stove will result in the stove's center of gravity, including the chimney, being high, making the stove unstable.

[0007] Therefore, in order to safely and reliably install a stove with a chimney attached, for example, Non-Patent Document 1 describes a method of attaching one end of a rope via a carabiner to multiple rings on a spark arrestor attached to the top of the chimney, and securing the other end of the rope to the ground using a peg.

[0008] [Patent Document 1] JP 2022-52746 A (Claim 1, Figure 2) [Non-patent literature]

[0009] [Non-Patent Document 1] "How to assemble, use, and clean up the Wienerwell Nomad View wood stove," [online], Monoreview website, [searched February 22, 2024], Internet (URL: https: / / monorebyu.com / archives / 25185.html) Summary of the Invention [Problem to be solved by the invention]

[0010] The wood stove installation method described in Non-Patent Document 1 requires multiple ropes to be secured with uniform force at positions on the ground that are symmetrical around the top of the chimney, which poses the following challenges:

[0011] (a) It requires a relatively flat and somewhat open area, so it takes time to find such a place.

[0012] (b) Because the rope stretches over a wide area compared to the size of the stove, even if people can see the stove and take precautions, they may neglect to pay attention to the rope, and there is a risk that they may get their legs or body caught in the rope and cause the stove to fall over. This is especially true in the evening and at night, when people have difficulty seeing the thin rope, making it even more dangerous.

[0013] (c) The wood stove installation method described in Non-Patent Document 1 cannot be used unless a spark arrester or chimney with multiple rings, such as the spark arrester described in Non-Patent Document 1, is used.

[0014] (d) Since multiple ropes must be fixed with uniform force at positions on the ground that are symmetrical around the top of the chimney, skill and experience are required.

[0015] (e) Stoves and chimneys are usually designed to be compact and often assembled. Therefore, just assembling the stove and chimney takes a lot of time and effort, and stringing multiple ropes further increases the time and effort required.

[0016] To provide a stove set and a stove installation method which can install a stove safely and surely even in an uneven and narrow place without requiring special tools, skill or experience, and with a short time and a small amount of work. [Means for solving the problem]

[0017] The stove set of the present invention is a stove set comprising a stove having a furnace body, a chimney, and a plurality of legs, and an installation jig for installing the stove on the ground, wherein one end of each of the legs is attached to the bottom surface of the furnace body so that a first angle formed between the bottom surface and the surface of each of the legs facing the bottom surface is an obtuse angle of 90° or more, at least one through hole is formed in each of the legs at a predetermined distance from the other end that contacts the ground, and the installation jig has a pointed portion at one end.

[0018] In the stove set of the present invention, each leg is provided with a guide that guides the second angle formed between the installation jig inserted into the through hole and the surface facing the bottom surface of each leg to be an acute angle of 90° or less.

[0019] In the stove set of the present invention, the first angle is greater than or equal to 90° and less than or equal to 135°, the predetermined distance is greater than or equal to 50 mm and less than or equal to 60 mm, and the second angle is greater than or equal to 30° and less than or equal to 90°.

[0020] The stove installation method of the present invention is a stove installation method for installing a stove on the ground, which has a furnace body, a chimney, and a plurality of legs, one end of each of which is attached to the bottom surface of the furnace body so that a first angle formed between the bottom surface and the surface of each of the legs facing the bottom surface is an obtuse angle of 90° or more, and the plurality of legs have at least one through hole formed in them at a predetermined distance from each of their other ends that contact the ground, the method comprising a first step of placing the stove on the ground, and a second step of inserting a pointed portion of an installation jig having a pointed portion at one end into the through hole formed in each of the legs, and burying the stove in the ground so that a second angle formed between the surface of each of the legs facing the bottom surface and the installation member is an acute angle of 90° or less.

[0021] In the stove installation method according to the present invention, each of the legs is provided with a guide that guides the second angle to be an acute angle of 90° or less.

[0022] In the stove installation method of the present invention, the first angle is greater than or equal to 90° and less than or equal to 135°, the specified distance is greater than or equal to 50 mm and less than or equal to 60 mm, and the second angle is greater than or equal to 30° and less than or equal to 90°. [Effects of the Invention]

[0025] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1. One embodiment [Structure of Stove Set 1] FIG. 1 is a perspective view seen from diagonally front right, showing an example of the configuration of a stove 11 that constitutes a stove set 1 according to one embodiment of the present invention.

[0026] 2 is a partial perspective view seen from the upper left showing an example of the installation state of the stove set 1, and FIG. 3 is a partial enlarged perspective view seen from the left side showing an example of the installation state of the stove set 1.

[0027] The stove set 1 includes a stove 11 and an installation jig 12. The stove 11 is composed of a furnace body 21, a chimney 22, and legs 23.

[0028] A through-hole (not shown) is formed at one end of the upper part of the furnace body 21, which communicates with the interior where firewood, artificial firewood, wood pellet fuel, etc. are burned. The through-hole is configured so that a chimney 22 can be attached. Windows 21A to 21C are attached to the front and both side surfaces of the furnace body 21.

[0029] The chimney 22 is attached to a through-hole in the furnace body 21, and communicates with the inside of the furnace body 21 to discharge smoke to the outside. The chimney 22 may be constructed as either a collapsible type or an extendable type.

[0030] Here, the term "assembly type" refers to a method in which the overall length is expanded by sequentially fitting or fastening the ends of multiple members of approximately the same size by screwing, etc. The term "extendable type" refers to a method in which multiple tapered members of successively smaller size can be stacked and housed inside a tapered member of the largest size by translating them in parallel, and the overall length is expanded by sequentially translating each member during installation and fastening the ends of each member by fitting, etc.

[0031] One end of each of the four legs 23 is attached near the four corners of the bottom surface 21E of the furnace body 21 so that the angle (first angle θ) formed between each leg 23 and the bottom surface 21E is an obtuse angle of 90° or more (90°≦θ<180°). The method of attaching each leg 23 to the furnace body 21 may be, for example, by screwing or welding. Alternatively, a rotation shaft may be attached near the four corners of the bottom surface 21E, and all or part of each leg 23 may be attached so as to be rotatable around the rotation shaft.

[0032] Each leg 23 may be constructed as either the assembly type, the telescopic type, or the foldable type. Here, the foldable type refers to a system in which a plurality of members of successively smaller dimensions can be rotated and moved inside a member of the largest size so that they can be stacked and stored, and when installed, the entire length can be expanded by rotating and moving each member in order and fixing the ends of each member by fitting or the like.

[0033] Near the lower end of each leg 23 whose overall length is expanded, a circular or elliptical through-hole 23A into which the installation jig 12 is inserted is formed.

[0034] The installation jig 12 is configured by integrally forming a rod-shaped portion 12A and a disk portion 12B provided at one end of the rod-shaped portion 12A. Although not shown, the other end of the rod-shaped portion 12A is provided with a pointed portion for embedding in the ground.

[0035] The furnace body 21 is made of, for example, steel such as stainless steel or carbon steel, duralumin, titanium, or casting. The chimney 22 and each leg 23 are made of, for example, stainless steel, steel, duralumin, titanium, or the like. The windows 21A to 21C are made of, for example, heat-resistant glass.

[0036] The installation jig 12 is made of, for example, a metal such as stainless steel, aluminum, steel, duralumin, titanium, or a synthetic resin. If the installation jig 12 is made of a relatively soft material such as synthetic resin, a reinforcing member made of a metal such as stainless steel, aluminum, steel, duralumin, titanium, or the like may be attached to the pointed portion.

[0037] [Example of dimensions of each part of Stove Set 1] (i) Furnace body 21 of stove 11 Width (W): 180~260mm, Depth (D): 270~420mm, Height (H): 230~400mm (ii) Chimney 22 (assembled) for stove 11 Unit cylinder length: 200-350mm, Unit cylinder outer diameter: 60-70mm (iii) Stove 11 legs 23 (assembly type) Length of unit leg: 250~350mm, diameter of through hole 23A: 4~15mm, Distance DH from the end of the leg 23 that comes into contact with the ground to the through hole 23A (see Figure 4): 50 to 60 mm (iv) Installation jig 12 Total length of installation jig 12: 300 to 600 mm, diameter of rod-shaped portion 12A: 3 to 10 mm

[0038] [Example of dimensions of stove set 1 when installed] (i) Distance between one end of each leg 23 in the longitudinal direction: 350 to 650 mm (ii) Distance between one end of each leg 23 in the short side direction: 200 to 500 mm (iii) Height from the ground 13 to the plane 21D of the furnace body 21: 300 to 600 mm (iv) Height from the ground 13 to the bottom surface 21E of the furnace body 21: 120 to 400 mm (v) Total length of chimney: 1500~2000mm (vi) First angle θ (the angle between the bottom surface 21E of the furnace body 21 and the inner surface 23B of the leg 23 facing the bottom surface 21E) (see FIG. 4): 90°≦θ≦135°

[0039] If the first angle θ is less than 90°, a load is applied to the connection between each leg 23 and the furnace body 21, making each leg 23 more likely to come off and preventing stable support of the furnace body 21. On the other hand, if the first angle θ is greater than 135°, a load is applied to the connection between each leg 23 and the furnace body 21, making each leg 23 more likely to come off and posing a risk of a person getting their leg caught on a leg 23 and causing the stove 11 to fall over.

[0040] [How to install Stove 11] (1) First, the user assembles the stove 11 by attaching the four legs 23 to the bottom surface 21E of the furnace body 21 and attaching the chimney 22 to a through-hole (not shown) in the flat surface 21D of the furnace body 21.

[0041] (2) Next, the user places the assembled stove 11 on the desired ground 13 as shown in FIG.

[0042] (3) Next, as shown in Figures 2 and 3, the user inserts the pointed portion of the rod-shaped portion 12A that constitutes each installation jig 12 into the through hole 23A formed in each leg 23, and then buries it in the ground 13.

[0043] Figure 4 is an abstract diagram of an example of the state in which the stove set 1 is installed on the ground 13. In Figure 4, the first angle θ is the angle between the bottom surface 21E of the furnace body 21 and the inner surface 23B of the leg 23 that faces the bottom surface 21E. The second angle φ is the angle between the installation jig 12 inserted into the through hole 23A of each leg 23 and the inner surface 23B of each leg 23.

[0044] In step (3), the user must ensure that the second angle φ shown in Figure 4 is an acute angle of 90° or less (0°<φ≦90°), preferably 30°≦φ≦90°, and that at least half of the total length of each installation jig 12 is embedded in the ground 13. In Figure 4, reference numeral 12C denotes the aboveground portion of the installation jig 12, and reference numeral 12D denotes the underground portion of the installation jig 12.

[0045] This is because, as shown in Figure 4, the leg 231, the installation jig 121, and the ground 13 form a triangle ABC, and the leg 232, the installation jig 122, and the ground 13 form a triangle DEF, so even if an external force is applied to the stove 11 for some reason, the stove set 1 can be stably installed on the ground 13.

[0046] For example, in FIG. 4, when a force F1 is applied to the leg 231, if the installation jig 121 is not embedded, the stove 11 will tend to tip in the direction R around point C shown in FIG.

[0047] On the other hand, if the installation jig 121 is embedded, a reaction force F2 acts on the installation jig 121, and the force F1 is cancelled out at point A shown in FIG.

[0048] Furthermore, as force F1 is applied to leg 231, force F3 is applied to leg 232, and if installation jig 122 is not embedded, stove 11 will tend to tip over in direction R in FIG.

[0049] On the other hand, if the installation jig 122 is embedded, a reaction force F4 acts on the installation jig 122, which cancels out the force F3 at point D shown in FIG.

[0050] The above-described mutual cancellation of forces occurs almost simultaneously between the other two legs 23 and the two installation jigs 12. In other words, reaction forces that cancel out the external forces acting on each leg 23 act mutually between the four legs 23 and the four installation jigs 12, allowing the stove 11 to be installed safely and reliably.

[0051] According to experiments, as shown in Figures 2 and 3, when the stove 11 was installed, the stove 11 remained installed without any problems even when a 20 kg weight was placed on the flat surface 21D of the furnace body 21. Furthermore, as shown in Figure 1, when the chimney 22 with a total length of 1560 mm was attached to the furnace body 21, the stove 11 remained installed without any problems even when a 10 kg weight was attached to the top of the chimney 22.

[0052] If the second angle φ is less than 30°, the vector components of the reaction forces F2 and F4 that oppose the external forces F1 and F3 are small, and therefore the furnace body 21 cannot be supported.

[0053] On the other hand, if the second angle φ is greater than 90°, the vector components of the reaction forces F2 and F4 that oppose the external forces F1 and F3 are small, so the furnace body 21 cannot be supported, and there is a risk that a person may get their leg or other part of their body caught on the installation jig 12 and cause the stove 11 to fall over.

[0054] Furthermore, the reason why more than half of the total length of each installation jig 12 is embedded in the ground 13 is that the center of gravity of each installation jig 12 is located in the ground 13 or underground, making it difficult for each installation jig 12 to come out.

[0055] [Effects of this embodiment] As described above, according to this embodiment, the following effects can be obtained. (a) The location where the stove 11 is installed does not necessarily have to be flat, as long as there is enough space to prevent fires and the like from occurring due to the radiant heat from the stove 11.

[0056] 5 is a partially enlarged perspective view showing an example of the stove set 1 installed on uneven ground. As can be seen from this figure, the stove 11 can be installed safely and reliably even in a location where there is a gap D between the right front leg 23 and the ground 13.

[0057] Therefore, compared to the conventional case, there are more options for where to install the stove 11, and the time required to install the stove 11 is accordingly shorter.

[0058] (b) Since there is no need to tension ropes as in the past, people only need to pay attention to the stove 11, and therefore there is less risk of the stove tipping over.

[0059] (c) Since there is no need to use special equipment such as a spark arrestor with multiple rings or a chimney, the stove 11 can be manufactured and sold inexpensively.

[0060] (d) Since the installation jig 12 is simply embedded in the ground 13, no special skills or experience are required compared to conventional methods, and the stove 11 can be installed in a short time with a small amount of work.

[0061] 2. Application Examples Although an embodiment of the present invention has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and the present invention also includes design changes and the like that do not deviate from the gist of the present invention.

[0062] [First application example] In the embodiment described above, an example was shown in which one through-hole 23A is formed in each leg 23, but this is not limited thereto, and multiple through-holes 23A may be formed in each leg 23. With this configuration, even if stove 11 is unavoidably installed on ground containing rocks or rubble, through-hole 23A with an appropriate second angle φ can be selected, and installation jig 12 can be embedded, for example, in a gap between rocks or rubble. This increases the options for installation locations for stove 11.

[0063] [Second application example] In the above embodiment, an example in which a through hole 23A is simply formed in each leg 23 is shown, but this is not limiting. For example, in order to guide the insertion angle of the installation jig 12, i.e., the second angle φ, to an appropriate angle, a guide portion may be formed in advance in each through hole 23A, or a guide member may be prepared to be attached to each through hole 23A. With this configuration, even a user such as a young person or a beginner at outdoor activities can easily embed the installation jig 12 in the ground.

[0064] [Third application example] In the above embodiment, an example was shown in which four legs 23 were attached near the four corners of the bottom surface 21E of the furnace body 21, but this is not limited to this. For example, as described in Patent Document 1, two legs may be attached near both ends in the longitudinal direction of the bottom surface 21E of the furnace body 21 so as to be rotatable around the vicinity of the ends.

[0065] [Fourth application example] In the above embodiment, each installation jig 12 is configured by integrally forming a rod-shaped portion 12A and a disk portion 12B provided at one end of the rod-shaped portion 12A, but is not limited to this. For example, a ring may be provided near the disk portion 12B of each installation jig 12.

[0066] The stove 11 may be placed on the ground 13, and after inserting each installation member 12 into each through-hole 23A of each leg 23 and embedding it in the ground 13, a rope may be stretched between the rings of the diagonally opposite installation jigs 12. This makes it difficult for each installation jig 12 to come out of the ground 13, allowing the stove 11 to be installed even more safely and reliably. [Explanation of symbols]
