Description

[Technical Field]

[0001] This invention relates to a foldable incinerator comprising a furnace portion consisting of a bottom and sidewall portions. [Previous Technology]

[0002] A fire pit is used for heating or cooking during outdoor recreation such as camping. It is made of metal and is heavy and large because it is used to collect fuel such as firewood or branches or fallen leaves.

[0003] Therefore, as an easy-to-carry fire platform, there are assembled fire platforms that combine four side plates and place a base plate in the center (e.g., Patent Document 1), or foldable fire platforms that install a furnace on a support platform formed by combining frames (e.g., Patent Document 2).

[0004] However, even if these fire pits can be divided into small volumes for storage, multiple operations must be performed in a prescribed order when assembling or organizing them, so outdoor assembly and other operations may not be easy.

[0005] Furthermore, if the number of components increases, there is a risk of losing some components, and there is also a possibility that the fire platform cannot be used repeatedly for a long period of time.

[0006] Therefore, in order to comfortably enjoy outdoor leisure, it is desirable to develop a foldable fire pit that can be easily set up by anyone and is easy to move or store. [Prior Art Documents] [Patent Documents]

[0008] [The problem the invention aims to solve]

[0009] The objective of this invention is to provide a foldable incinerator that is not only highly portable and easy to assemble, but also possesses sufficient strength for field use. [Means of the Problem]

[0010] In order to solve the above-mentioned problems, the inventors have discovered that by including: a bottom that can be folded freely by connecting two bottom plate members in a manner that allows one of their edges to be rotated as an axis, and a side wall portion that includes a standing mechanism that stands up as the bottom plate members are rotated and unfolded on the side edge of the bottom intersecting the aforementioned axis, the furnace part can be easily assembled or stored, thereby completing the present invention.

[0011] That is, the present invention is a folding incinerator, characterized in that it is provided with a furnace part, which includes: a bottom, formed by connecting two bottom plate members in such a way that one of their edges can be rotated as an axis; and a side wall part, wherein the side edge of the bottom intersecting the above-mentioned axis includes an erecting mechanism that stands up as the bottom plate members rotate and unfold.

[0012] Further, the present invention is a folding fire stand, characterized in that: the inclined side edges of two adjacent bottom plate members formed by cutting the side edges of the bottom that intersect the axis of rotation into a roughly U-shape are rotatably connected to the lower edge of the side wall portion, thereby the side wall portion stands up as the bottom plate members rotate.

[0013] Further, the present invention is a folding incinerator, characterized in that: the lower edge of the side wall is connected in a manner that allows it to slide along the inclined side edge of the base plate member.

[0014] Further, the present invention is a folding incinerator, characterized in that: the side wall is formed by connecting two side wall plate components in a manner that allows them to rotate on the axis of rotation of the base plate component.

[0015] Further, the present invention is a folding incinerator, characterized in that: the two side wall panel components include a rotation control means for rotating within a predetermined angle range.

[0016] Further, the present invention is a folding incinerator, characterized in that: the front edge and / or rear edge of the bottom are connected to the plate in a rotatable manner.

[0017] Further, the present invention is a folding incinerator, characterized in that: a plurality of foot members are provided on the lower surface of the bottom formed by rotating and unfolding two base plate members, and includes: a separating force-applying means for separating the two foot members located opposite each other on the lower surface of the bottom across the axis of rotation of the base plate members; and a movable connecting means for connecting the foot members to the base plate members in a manner that allows them to move from one edge side of the base plate members, which is the axis of rotation, towards the opposite edge side; thereby, if the base plate members are rotated and the bottom is unfolded, the foot members unfold to the left and right along the lower surface of the bottom as the base plate members rotate. [Effects of the Invention]

[0018] According to the folding incinerator of the present invention, if the bottom plate component is rotated and the bottom is unfolded, the side wall portion rises to form the furnace portion as the bottom plate component rotates, and the incinerator can be easily assembled.

[0019] Furthermore, by including a force-applying means and a movable connection means on the lower surface of the bottom, and by arranging a foot member, if the bottom plate member is rotated and the bottom is unfolded, the foot member unfolds to the left and right along the lower surface of the bottom as the bottom plate member rotates, thus making it easier to assemble the fire platform.

[0020] On the other hand, if the bottom plate component is rotated and the bottom is folded, the side wall portion tilts down and is folded together with the two bottom plate components for storage. Furthermore, since the foot component can be stored between the two bottom plate components, the fire platform can be easily transported.

Implementation Method

[0022] The folding incinerator of the present invention will be described below with reference to the figures. However, the present invention is not limited to the form shown for implementation. Furthermore, the connection or installation of the constituent components of the present invention includes not only direct connections, but also connections between other components, etc. As long as the relative positional relationship of the installation parts of the two components to be targeted remains substantially constant, there is no particular limitation, and all are included therein.

[0023] The folding incinerator of the present invention is shown in FIG1. ​​It is characterized in that it includes a furnace part 8, which is provided with: a bottom 5, which is connected by two bottom plate members 2 and 3 in such a way that one of their edges can be rotated as an axis 4 to form a foldable structure; and side wall parts 6 and 7, which include a standing mechanism 9 on the side edge of the bottom that intersects with the axis and unfolds as the bottom plate members rotate.

[0024] Figure 1 illustrates a bottom formed by connecting two bottom plate components, and a furnace section formed by arranging one side wall on each side of the bottom. However, the side wall is not necessarily limited to two; it may be arranged on either side, depending on the purpose or shape of the combustion chamber. Furthermore, the bottom plate components are not limited to two pieces; three or more pieces may be arranged, with adjacent bottom plate components rotatably connected to form the bottom. In this case, a side wall including an erecting mechanism may be provided on each of the two adjacent bottom plate components at a position intersecting the axis of rotation.

[0025] There are no particular limitations on the erection mechanism provided on the side wall. For example, the bottom and the side wall can be connected by an elastic body, and the side wall can be erected when the base plate member is rotated and unfolded by the elastic force brought by the elastic body. Alternatively, by using an elastic material in a part of the side wall, it can also be erected as the base plate member rotates.

[0026] The standing mechanism 9 can be formed by the shape of the base plate member, the shape of the side wall portion, and the connection means between the base plate member and the side wall portion as shown in FIG3. That is, the inclined side edges of two adjacent base plate members, which are formed by cutting the side edge of the bottom that intersects the axis of rotation into a roughly U-shape, are rotatably connected to the lower edge of the side wall portion, thereby allowing the side wall portion to stand up as the base plate member rotates.

[0027] Figure 4 shows the unfolding or folding action of the folding fire platform. However, on the side wall 7 including the standing mechanism 9 shown in Figure 3, if the two adjacent bottom plate members slowly rotate and unfold from below to the left and right, and reach the position where the two bottom plate members form an angle of 180 degrees (c), and then become a state of further upward rotation (d), the side wall stands up upward.

[0028] The connection between the base plate member and the side wall portion can be made in such a way that the lower edge of the side wall portion can slide along the inclined side edge of the base plate member. As shown in Figure 3, the lower edge of the side wall portion 7 is rotatably connected to the inclined side edge of the base plate members 2 and 3. By connecting in such a way that it can slide along the inclined side edge of the base plate member, the rotation of the base plate member becomes smooth, and the side wall portion can be easily erected.

[0029] The side wall portion 7 can be formed by connecting two side wall panel members 10 and 11 in a manner that allows them to rotate on the axis 4 of rotation of the base plate member. According to the side wall portion described above, as shown in FIG4, in the state (a) where the two base plate members are rotated downwards and folded up, the side wall portion can be bent into two parts on the axis 4 of rotation of the base plate member and stored in a small volume (FIG. 5). On the other hand, in the unfolded state of the folding fire station, the side wall portion can be erected approximately vertically along the bottom cut into a roughly U-shape (FIG. 2).

[0030] The two connected side wall panel members may include a rotation control means for rotating within a predetermined angle range. As shown in FIG4, if the two base plate members are slowly rotated upward from the folded state (a), the two side wall panel members also rotate upward together with the base plate members until the base plate members are unfolded to a state of 180 degrees (c). Moreover, if the base plate members are rotated further upward, the two side wall panel members will not rotate upward from the 180-degree position, but the side walls will stand up and rotate along the side edge of the bottom cut into a roughly U-shape. Therefore, since the two side wall panel members rotate differently from the base plate members, if a rotation control means for rotating within a predetermined angle range is provided, the side wall panel members will move smoothly, making it easy for the side walls to stand up. For example, the two side wall members may include a rotation control means to prevent further upward rotation after unfolding to 180 degrees.

[0031] If the rotation control method is to control the rotation of the two side panel members within a predetermined angle range, there are no particular limitations, and all methods can be used. For example, the following methods can be widely used: limiting the width of the notch of the hinge connecting the two side panel members to a predetermined range to restrict the range of rotation angle (not shown); or providing a protrusion near the connection point of the two side panel members, which acts as an obstacle to restrict the range of rotation (not shown), etc. The angle range formed by the two rotating side panel members is preferably set to 0 to 170 degrees.

[0032] Furthermore, if the two side panel members are connected by an elastic body such as a spring in order to rotate within a predetermined angle range, the side panel members are subjected to the force of the elastic body and can be smoothly rotated and erected along the side edge of the bottom cut into a roughly U-shape (not shown).

[0033] Figure 4 shows the following configuration: two adjacent base plate members are slowly rotated and unfolded from below to the left and right. From the state where the two base plate members reach an angle of 180 degrees (c), they are further rotated upwards (d), thereby raising the side wall to form the furnace section. Conversely, even if the two adjacent base plate members are rotated vertically upwards to a closed state, and from this closed state, the two base plate members are slowly rotated downwards and unfolded to the left and right, the configuration shown in Figure 4 (d) can be achieved, raising the side wall to form the furnace section (not shown). In this case, when the burner is folded up, the side wall is folded and housed between the two base plate members, or protrudes from the two base plate members in the form shown in Figure 5 (b).

[0034] As shown in Figure 1, the plates 12 and 13 can be rotatably connected to the side edge of the bottom 5, which is approximately parallel to the axis of rotation 4. After use, the folding fire stand can be folded up by rotating the bottom plate component for storage (Figure 4). However, when the bottom plate component is folded up, the upper surface of the bottom where firewood or the like has burned is exposed as the outer side of the folded bottom plate component. Therefore, when the plates 12 and 13 are set and stored at the front and rear edges of the bottom, firstly, the bottom plate component is rotated to cover the upper surface of the bottom. Secondly, if the bottom plate component is folded up, the hands holding the bottom plate component will not get dirty, making it easy to carry. Furthermore, as shown in Figure 2, the folding fire stand can be used in a roughly vertical standing state. However, by setting it in the above-described form, even in crosswinds, fire can be safely lit. Moreover, if a net or the like is placed on the upper edge of the plate, food can also be cooked on it.

[0035] The plate is usually set on the front edge and the rear edge of the bottom, but depending on the size or shape of the fire platform, it may also be set on either the front edge or the rear edge of the bottom.

[0036] As shown in FIG1, the folding fire stand 1 has a plurality of leg members on the lower surface of the bottom 5 formed by rotating and unfolding two base plate members 2 and 3. It may also include: a separating force-applying means 16 for separating two leg members 14 and 15 located on opposite sides of the lower surface of the bottom across the axis of rotation 4 of the base plate members 2 and 3; and a movable connecting means 17 for connecting the leg members to the base plate members in a manner that allows them to move from one edge side of the base plate member that forms the axis of rotation towards the opposite edge side. The structure described above, including leg members, a separating force-applying means, and a movable connecting means, is also used in the folding table disclosed in Japanese Patent No. 6141698. Furthermore, although FIG1 illustrates a fire stand with four leg members, it is not limited to this; a number of leg members more suitable for the size of the bottom 5 can be configured.

[0037] By using the separating force application means 16, force is applied to separate the two foot members 14 and 15, which are located opposite each other on the axis 4 of rotation of the base plate members 2 and 3. By using the movable connection means 17, the foot members are connected to the base plate members in such a way that they can move from one edge side of the base plate members that is the axis of rotation 4 to the opposite edge side. In this way, if the base plate members 2 and 3 are rotated and the bottom 5 is unfolded, the two foot members 14 and 15, which are subjected to force, move their connection positions and unfold the lower surface of the bottom 5 to the left and right as the base plate members 2 and 3 rotate, so that the folding fire platform can be unfolded and installed. Furthermore, if the base plate members 2 and 3 are rotated and the bottom 5 is folded, the two foot members, which are pressed from the left and right sides by the lower surfaces of the two base plate members, retract towards the center while resisting the applied force, and can be stored between the two base plate members 2 and 3, so that the folding fire platform can be stored (Figs. 10(a) to (e)).

[0038] The shape or material of the separating force-applying means 16 is not particularly limited if it has the function of applying force to separate the two leg members 14 and 15 and unfold them to the left and right. Therefore, the separating force-applying means 16 can, for example, adopt a means of connecting the two leg members 14 and 15 with an elastic body and using the elastic force of the elastic body to separate the two leg members. However, if a means of connecting a portion of the two leg members formed by the elastic body to each other and using the elastic force of the elastic body to separate the two leg members is adopted, the separating force-applying means and the leg members can be formed into one piece, which can reduce the number of components. In this way, a folding incinerator with excellent strength, light weight and excellent portability can be formed.

[0039] Furthermore, as shown in FIG7, the first rotating connection 18 and the second rotating connection 19 can be separated and configured along the axis 4 of rotation of the base plate members 2 and 3 (FIG6). The first rotating connection 18 forms two rod-shaped elastic bodies (e.g., elastic metal rods) of the two foot members 14 and 15, with the front end of the lower end extension 14d extending from the lower end 14b of one foot member 14 and the front end of the upper end extension 15c extending from the upper end 15a of the other foot member 15 connected in a horizontally rotatable manner. The second rotating connection 19 connects the front end of the upper end extension 14c extending from the upper end 14a of one foot member 14 and the front end of the lower end extension 15d extending from the lower end 15b of the other foot member 15 in a horizontally rotatable manner.

[0040] As shown in FIG7(b), a cylindrical tube can be used to insert the bent front ends of the upper extension 15c and the bent front ends of the lower extension 14d into the openings at both ends of the first rotating connection 18 from the vertical direction, and the bent front ends of the upper extension 14c and the bent front ends of the lower extension 15d into the openings at both ends of the second rotating connection 19 from the vertical direction. In this way, the upper extension 15c and the lower extension 14d, and the upper extension 14c and the lower extension 15d can be connected in a manner that allows them to rotate in the horizontal direction.

[0041] In the force-applying separation means 16 described above, as shown in FIG9, if the two leg members 14 and 15 approach each other, the first rotating connection 18 and the second rotating connection 19 approach each other, and the relative positions of the upper and lower extensions at both ends of the leg members change. As a result, the rod-shaped elastic body (e.g., an elastic metal rod) generates an elastic force (a repulsive force that wants to return to its original position), which can be used to separate the two leg members 14 and 15 from each other. Here, focusing on the leg member 14, the main elastic force (repulsive force) generated by the approach of the two leg members 14 and 15 can be said to be generated against the torsional action exerted on the rod-shaped elastic body by the relative rotation of the upper extension 14c and the lower extension 14d about the axis of the leg member 14.

[0042] Furthermore, Figure 7 illustrates the following configuration: a first rotatable connection 18 is provided, in which the front end of the lower end extension 14d extending from the lower end 14b of one leg member 14 is connected to the front end of the upper end extension 15c extending from the upper end 15a of the other leg member 15 in a horizontally rotatable manner; and a second rotatable connection 19 is provided, in which the front end of the upper end extension 14c extending from the upper end 14a of one leg member 14 is connected to the front end of the lower end extension 15d extending from the lower end 15b of the other leg member 15 in a horizontally rotatable manner. However, as shown in Figure 8... As shown, the front ends of the upper extensions 14c and 15c extending from the upper ends 14a and 15a of the two foot members 14 and 15 are connected to each other in a horizontally rotatable manner to form a first rotating connection. The front ends of the lower extensions 14d and 15d extending from the lower ends 14b and 15b of the two foot members 14 and 15 are connected to each other in a horizontally rotatable manner to form a second rotating connection. The first rotating connection and the second rotating connection are separated and arranged along the axis 4 of rotation of the base plate members 2 and 3, so that an elastic force can be applied to separate the foot members.

[0043] As shown in FIG6, the movable connection means 17 can be provided on the lower surface of the base plate members 2 and 3, and guide members 21 and 23 having through holes 20 and 22. The through holes 20 and 22 extend from one edge side of the base plate member that serves as the axis of rotation 4 toward the opposite edge side, and have an opening surface that is substantially perpendicular to the lower surface of the bottom 5. By inserting the upper end extensions 14c and 15c extending from the upper ends 14a and 15a of the foot members 14 and 15 into the through holes 20 and 22 of the guide members 21 and 23, the foot members can be connected to the base plate members in such a way that the foot members can be moved from one edge side of the base plate member that serves as the axis of rotation 4 toward the opposite edge side.

[0044] The guide member is connected in such a way that the upper extension of the foot member is inserted into a through hole provided on the guide member, so that the foot member can move along the lower surface of the base plate member. Therefore, there must be at least one through hole in each foot member. However, by inserting different parts of the upper extension of the foot member into a plurality of through holes provided on the guide member, the movement direction of the upper extension can be more reliably restricted. In the guide member 21 shown in FIG6, in addition to the through hole 20, a through hole 28 is also provided. By inserting the upper extension 14c of the foot member 14 into the through holes 20 and 28, the upper extension 14c can be reliably horizontally extended along the lower surface of the base plate member.

[0045] By means of the movable connection means 17 as described above, if the bottom plate members 2 and 3 are rotated and the bottom 5 is unfolded, the two legs 14 and 15 under force are moved and unfolded to the left and right through the through holes 20 and 22 of the guide members 21 and 23, and a folding fire platform can be provided (Figs. 10(a) to (e)). Furthermore, if the bottom 5 is folded by rotating the bottom plate members 2 and 3, the two legs 14 and 15 pressing from the lower surfaces of the two bottom plate members from the left and right counteract the force of the separating force application means 16. At the same time, the upper extensions 14c and 15c move into the through holes 20 and 22 and are gathered to the center and housed between the two bottom plate members 2 and 3, thereby folding the folding fire platform into a small volume.

[0046] The two base plate components 2 and 3 can be connected by installing hinges or other connecting devices, or a cylindrical part can be provided on the edge of each of the two connected base plate components, and a core component can be inserted into the cylindrical part to form a hinge structure, etc., so as to be connected in a rotatable manner. However, the two guide members 21 and 23, which are set apart from the axis 4, can be rotatably connected to the two rotating base plate components 2 and 3, so that the lower surfaces of the two base plate components face each other and the bottom 5 can be folded freely.

[0047] As described above, if the guide members 21 and 23 provided on the base plate members 2 and 3 are used to connect the two base plate members in a rotatable manner, the number of components can be reduced, thus making it a device with excellent strength and excellent portability by reducing weight.

[0048] Side walls 24, 25, 26, and 27 are provided on the lower surface of the base plate members 2 and 3, along an edge opposite to one edge of the axis 4 of the rotating base plate member, so that a shallow recess surrounded by the side walls and guide members can be formed on the lower surface of the base plate members. If a shallow recess 29 is formed on the lower surface of the base plate members as described above, the strength of the base plate members is increased, thus making the base plate members thinner and reducing the weight, and a fire platform with excellent transportability can be obtained (Fig. 2).

[0049] Furthermore, by providing sidewalls 25 and 27 on the lower surface of the base plate members 2 and 3 along the edge opposite to the axis of rotation 4, if the bottom is folded by rotating the two base plate members 2 and 3, the foot members 14 and 15, the force-applying means 16 and the moving connection means 17 can be accommodated in the space surrounded by the two base plate members 2 and 3 and the sidewalls 25 and 27, thus becoming a fire platform that is even easier to transport.
