[0003] [Patent Document 1] JP 2014-92313 A [Non-patent literature]

[0004] [Non-Patent Document 1] "All brass blowpipe "Nora Blaster"" [online], Nora Tool Factory, [searched on February 13, 2022], Internet<URL:https: / / norastove.stores.jp / items / 5e12fe985b120c072da017ff> Summary of the Invention [Problem to be solved by the invention]

[0005] The inventor of the present application had thought of providing a fire poker member on the outlet side of the blowtorch so that the blowtorch could also be used as a fire poker. However, providing a fire poker member would cause the fire poker member to protrude laterally from the blowtorch body, reducing storage capacity.

[0006] The present invention was made in consideration of the above circumstances, and its object is to create a blowtorch that has a fire poker function while also being easy to store. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the first invention is a blowtorch comprising a blowtorch body having a mouthpiece on one end and an outlet on the other end through which air blown in from the mouthpiece exits, and a fire poker member that is detachably connected to a side connector provided on the side of the blowtorch side of the blowtorch body and that protrudes laterally or diagonally from the blowtorch body while connected to the side connector.

[0008] The second invention is based on the first invention, in which the blowtorch body comprises a number of tubular rods including a first tubular rod with an air outlet, and one or more joints, and the multiple tubular rods are connected to form a single rod by the one or more joints, and the one or more joints include an air outlet side joint that connects the first tubular rod to one of the remaining tubular rods in the multiple tubular rods, and the air outlet side joint has a side connection portion to which the base side of the fire rake member is connected.

[0009] The third invention is based on the second invention, in which at least one of the connection parts to which the tubular rod material is detachably connected in one or more joints is formed so that the base side of the fire rake member can also be connected.

[0010] The fourth invention is a blowtorch comprising a blowtorch body having a mouthpiece on one end and an outlet on the other end as an exit for air blown in from the mouthpiece, and a mouthpiece part provided on one end of the blowtorch body and having a mouthpiece, the mouthpiece part having an outer member formed in a roughly tubular shape that widens toward the one end, and an inner member having a through hole that is embedded inside the one end of the outer member so that the through hole connects to the internal space of the outer member. Effect of the Invention

[0011] In this invention, the poker member can be removed from the side connection part of the blowtorch body. Therefore, the poker member can be stored without protruding sideways or diagonally from the blowtorch body. This invention realizes a blowtorch that has excellent storage properties while still having a fire poker function. [Brief description of the drawings]

[0012] [Figure 1] FIG. 1 is a diagram showing an assembled state of a blowtorch according to an embodiment. [Diagram 2] FIG. 2 is an exploded view of the blowtorch according to the embodiment. [Diagram 3] FIG. 3 is a diagram for explaining the structure and manufacturing method of the blowing tip part of the blowing stick according to the embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. Note that the following embodiments are merely examples of the present invention and are not intended to limit the scope of the present invention, its applications, or its uses.

[0014] [Blown away structure] This embodiment is a fire blower 1 that can also be used as a poker. As shown in FIG. 1, the fire blower 1 includes a fire blower body 10 and a fire poker member 25 that is detachably connected to a side connection part 21c provided on the side of the tip side of the fire blower body 10. The fire blower body 10 and the fire poker member 25 are made of metal, for example. A mouthpiece 10a is provided on one end side of the fire blower body 10. An air outlet 10b that serves as an outlet for air blown from the mouthpiece 10a is provided on the other end side (tip side) of the fire blower body 10. In addition, the fire poker member 25 protrudes laterally from the fire blower body 10 in a connected state connected to the side connection part 21c. The fire poker member 25 may be configured to protrude diagonally laterally from the fire blower body 10 in a connected state.

[0015] As shown in FIG. 1, the blowtorch body 10 comprises a number of tubular rods 11-14, a number of joints 21-23, and a nozzle part 20 attached to the tubular rod 14 closest to one end among the plurality of tubular rods 11-14. The number of joints 21-23 is one less than the number of tubular rods 11-14. The nozzle part 20 has a nozzle 10a. The blowtorch body 10 may be composed of two tubular rods 11-12 and one joint 21. Although the number of tubular rods 11-14 is four in this embodiment, it may be a number other than four.

[0016] The multiple cylindrical rods 11-14 are made up of a first cylindrical rod 11 provided with a blowout port 10b, a second cylindrical rod 12 connected to the first cylindrical rod 11, a third cylindrical rod 13 connected to the second cylindrical rod 12, and a fourth cylindrical rod 14 connected to the third cylindrical rod 13 and having a blowout part 20 attached thereto. In this specification, the blowout port 10a side of the blowout stick 1 may be referred to as the "upstream side" and the blowout port 10b side as the "downstream side".

[0017] Each of the tubular rods 11-14 is formed into a cylindrical, straight rod shape. The tubular rods 11-14 are arranged in order of length from shortest to longest as the first tubular rod 11, the second tubular rod 12, the third tubular rod 13, and the fourth tubular rod 14. The order of the lengths of the tubular rods 11-14 is not limited to that of the present embodiment.

[0018] The multiple joints 21-23 are composed of a first joint 21 connecting the first tubular bar 11 and the second tubular bar 12, a second joint 22 connecting the second tubular bar 12 and the third tubular bar 13, and a third joint 23 connecting the third tubular bar 13 and the fourth tubular bar 14. The first joint 21 corresponds to an outlet-side joint connecting the first tubular bar 11 and the most downstream tubular bar 12 among the remaining tubular bars 12-14 in the multiple tubular bars 11-14. A three-way joint is used for the first joint 21. A socket (screw-in joint) is used for the joints 22 and 23 other than the first joint 21.

[0019] The first joint 21 includes a first connection part 21a to which the upstream end 11b of the first cylindrical bar 11 is detachably connected, a second connection part 21b to which the downstream end 12a of the second cylindrical bar 12 is detachably connected, and a third connection part 21c to which the base end 25a of the poker member 25 is detachably connected. The third connection part 21c corresponds to a side connection part provided on the side of the first joint 21.

[0020] Similar to the first joint 21, the second joint 22 and the third joint 23 each have a first connection portion to which the lower end side tubular rod material 12-13 is detachably connected, and a second connection portion to which the upstream side tubular rod material 13-14 is detachably connected.

[0021] In the first to third joints 21 to 23, each of the connection parts has a connection structure in which a female screw is formed on the inner peripheral surface. A male screw formed on the outer peripheral surface of the end of the cylindrical bar 11 to 14 is screwed into each connection part. The side connection part 21c also has a connection structure in which a female screw is formed on the inner peripheral surface. A male screw formed on the outer peripheral surface on the base side of the fire rake member 25 is screwed into the side connection part 21c.

[0022] The fire poker member 25 is a straight rod and is shorter than any of the cylindrical rods 11 to 14. The tip of the fire poker member 25 is formed into a pointed shape. The fire poker member 25 is connected to the third connecting part 21c of the first joint 21, so that it protrudes laterally with respect to the extension direction of the blowtorch body 10.

[0023] [Structure and manufacturing method of blowing nozzle parts] Next, the mouthpiece part 20 will be described with reference to Fig. 3. Fig. 3(a) to (d) show the process of manufacturing the mouthpiece part 20, and Fig. 3(d) shows the mouthpiece part 20 in a completed state.

[0024] The mouthpiece part 20 includes an outer member 31 formed in a generally tubular shape expanding toward one end, and an inner member 32 having a through hole 33 and embedded inside one end of the outer member 31 so that the through hole 33 is connected to the internal space of the outer member 31. The outer member 31 and the inner member 32 are made of metal, for example. A reducing socket is used for the outer member 31. As shown in FIG. 3(a), a female thread 31a is formed on the inner peripheral surface of the other end of the outer member 31.

[0025] A hexagonal socket taper thread plug is used for the inner member 32. The inner member 32 is formed in a substantially cylindrical shape. The through hole 33 extends in the axial direction of the inner member 32. A male thread 32a that screws into the female thread 31a is formed on the outer circumferential surface of the inner member 32.

[0026] In manufacturing the mouthpiece part 20, first, a connecting step is performed in which the outer member 31 and the inner member 32 are connected by screwing the male thread 32a of the inner member 32 into the female thread 31a of the outer member 31. The inner member 32 and the outer member 31 are connected to each other coaxially. After the connecting step, the inner member 32 is embedded in one end side of the outer member 31, as shown in FIG. 3(b).

[0027] Next, a cutting step is performed in which the inner member 32 is cut from the outer surface side to form a tapered surface 32b that widens toward one end side on the inner member 32, as shown in Fig. 3(c). The tapered surface 32b is formed so as to widen radially outward from the edge of the through hole 33.

[0028] Finally, a coating step is performed to apply a rubber coating 35 to one end of the connected outer member 31 and inner member 32, as shown in Fig. 3(d). In Fig. 3(d), the rubber coating 35 is hatched. The rubber coating 35 can be formed, for example, by spraying liquid rubber. By performing the above steps, the mouthpiece part 20 is completed.

[0029] [Effects of this embodiment] In this embodiment, the fire poker member 25 is firmly connected to the blowtorch body 10, so that the blowtorch 1 can be used to strike or pull the firewood.

[0030] In this embodiment, when the blowtorch 1 is used, the multiple cylindrical rods 11-14 are connected to each other by the multiple joints 21-23 to form a single rod. When storing the blowtorch 1, the blowtorch 1 can be disassembled into multiple rod-shaped bodies as shown in FIG. 2. In particular, in this embodiment, the poker member 25 can be removed from the first joint 21. Therefore, the blowtorch 1 can be disassembled without the poker member 25 protruding to the side. According to this embodiment, a blowtorch 1 that has a fire poker function and is easy to store can be realized.

[0031] In this embodiment, at least one of the connection parts (first connection part, second connection part) to which the cylindrical rods 11-14 are detachably connected in the multiple joints 21-23 is formed so that the root side of the fire rake member 25 can also be detachably connected. In this embodiment, all of the connection parts of the first to third joints 21-23 have the same dimensions as the third connection part 21c of the first joint 21, and can connect the root side of the fire rake member 25. The fire rake member 25 can be connected to the joints 22 and 23 in addition to the first joint 21. Here, since the fire rake member 25 is short in length, there is a risk that it will get mixed up with outdoor equipment if it is stored without being connected to other components. In contrast, in this embodiment, as shown in FIG. 2, the fire rake 1 in a disassembled state can be stored in a state in which the fire rake member 25 is connected to any of the cylindrical rods 11-14, so that the above-mentioned mixing up can be suppressed.

[0032] In this embodiment, the material of the blowtorch 1 is the gas piping material that serves as the gas distribution path (for example, the material of exposed piping used in buildings). Specifically, gas pipes (piping material used as gas pipes) are used for each of the cylindrical rods 11-14. Gas pipe joints used to connect gas pipes are used for each of the joints 21-23. In this embodiment, using the gas piping material for the blowtorch 1 results in a blowtorch with a unique design.

[0033] Here, in laying a gas pipe, it is necessary to firmly connect the gas pipe and the gas pipe joint, so the dimensional difference between the male thread of the gas pipe and the female thread of the gas pipe joint is small. Therefore, if the gas pipe and the gas pipe joint are used as they are, it is not easy to manually connect or disassemble the tubular rods 11-14 (gas pipes) and the joints 21-23 (gas pipe joints). In contrast, in this embodiment, gas pipes whose male threads are thinned by thread cutting are used as the tubular members 11-14. Specifically, a 6A size gas pipe is used for each of the tubular rods 11-14, and a gas pipe joint corresponding to the 6A size gas pipe is used for each of the joints 21-23. The standard diameter of the male thread of the 6A size gas pipe is 9.728 mm. In this embodiment, the male thread of each of the tubular rods 11-14 is thinned to about 9 mm by thread cutting. Therefore, it is possible to realize an assembly-type blowtorch 1 that can be easily assembled and disassembled by hand while utilizing gas piping materials.

[0034] In this embodiment, the mouthpiece part 20 is also manufactured using the material of the gas piping. The mouthpiece part 20 is composed of an outer member 31 and an inner member 32. If the inner member 32 is not used, the air passage on the mouthpiece 10a side of the mouthpiece part 20 becomes too wide, making it difficult to effectively send air to the air outlet 10b. In contrast, in this embodiment, the inner member 32 is embedded inside one end side of the outer member 31 to narrow the air passage and effectively send air to the air outlet 10b. The outer member 31 and the inner member 32 may be made of a ready-made product other than the material of the gas piping, and even in this case, the mouthpiece part 20 that can effectively send air to the air outlet 10b can be manufactured from the ready-made product.

[0035] In this embodiment, a coating rubber 35 is applied to the mouthpiece 10a side of the mouthpiece part 20. This reduces the coldness of the metal felt when the user's lips touch the mouthpiece part 20. Also, if the tapered surface 32b formed by cutting is exposed, there is a risk of burrs piercing the user, but since the tapered surface 32b is covered with the coating rubber 35, such a problem does not occur.

[0036] <Other embodiments> In the above-described embodiment, the poker body 10 having the side connection portion 21c may be entirely or partially configured to be extendable.

[0037] In the above embodiment, the blowtorch 1 is made of a material used for gas piping, but the blowtorch 1 may be made of a material other than a material used for gas piping. [Industrial Applicability]

[0038] The present invention can be applied to blowtorches and the like used in outdoor scenes. [Explanation of symbols]
