Description

BACKGROUND OF THE INVENTION

(a) Field of the Invention
The present invention relates to a torch, and more particularly to a wind-proof torch which can be installed in an upright position or carried for lightening in outdoor camping. The torch body is mixed with a natural fiber and its outer surface is protected by a combustible confining material, such that its upper end will not be affected by air flow in order to maintain a transversally descending thermal interaction. In addition, the torch can be applied in any places in association with an elastic multi-functional handling bar.
(b) Description of the Prior Art
A torch is used for lightening in outdoor camping as it is not convenient to use electricity and people are pursuing an outdoor primitive mood. In order to extend the burning time of torch, kerosene is generally used which is enclosed by a fiber cloth to achieve a loner time of combustion. On the other hand, paraffin is even used as a combustion material. As shown in FIG. 1, a wax torch 1 made by paraffin is surrounded by a wrapping layer of paper 11 and is connected to a handling bar 12 at a bottom. Although a burning flame 10 can sustain with a longer time of combustion, the flame 10 will drift toward the other side of torch 1 when a wind pressure F is approaching the torch 1. As the flame 10 is provided with a thermal radiation effect, combustion will be spreading to a surface of opposite side of torch 1 due to that a heat wave will be attacking the surface of opposite side of torch 1 after the flame 10 is acted by the wind pressure F. Moreover, as the side surface is subjected to the thermal interaction of flame 10, a cracking 110 from carbonization can be easily formed on the wrapping layer 11, and the interior wax will be quickly molten from a heating up in large area by the flame 10 and will flow out of the burned-out cracking 110, thereby forming wax drops 100 at the outer surface and apparently constituting a slant firing line 111 at a bottom rim of combustion surface. If the torch 1 is used in a seaside, the sideways combustion effect described above can be easily formed by a pushing of sea wind, time used for lightening can be reduced by a large consumption of wax drops 100, and the fire can be easily extinguished when the wind pressure is large enough.

SUMMARY OF THE INVENTION

Accordingly, the present invention is to provide a torch having a wind-proof function, which is connected with a modular handling bar, so as to serve as a multi-functional wind-proof lightening after being connected with the modular handling bar and installed outdoors in an upright position.
The torch of present invention uses a large quantity of fiber yarns filled in the torch body to form a restricting function to fuel, and a confining material having a transient heat resistance function surrounding the torch body to impede a thermal radiation of sideways flakes to directly attack an interior of torch body, thereby maintaining an integrity of torch body. In addition, an elastic handling bar is provided to absorb a reaction force upon being intruded by an external force, so as to prevent the torch from losing a mechanical intensity by the external force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 2, a wind-proof torch 20 includes a torch body 2 filled with a large quantity of fiber yarns 21 having interspaces for incorporating a solid fuel 22. The plurality of fiber yarns can be used to fasten the fuel and form into a capillarity effect during a combustion process to impede a flow speed of fuel 22 which is in a solid state in a room temperature. An insertion hole 200 is located in an interior of torch body 2 at a longitudinal position.
The torch body 2 is composed of the solid fuel 22, which is in a solid state in the room temperature, mixed with a large quantity of fiber yarns 21, in a volume fraction of 50%. During a process of hot melting, the solid fuel 22 is subjected to the capillarity effect of fiber yarns 21, so as to cling onto a surface of fiber yarns above or intercede into gaps to form an expanded area for contacting with oxygen and accepting a high temperature, after being molten into a liquid.
The solid fuel 22 is further provided with debris 211 formed by smashing plant fibers. The debris 211 can be further carbonized in advance, such that pores can be formed inside the debris 211 to increase a capability for adsorbing the molten liquid and to form a heat resistance effect. The aforementioned debris 211 can be as tiny as a carbon powder, a char with larger grain, or a slack formed by exploring a coal mine.
Referring to FIG. 3, the aforementioned torch body 2 is surrounded with a combustible wrapping layer 3.
Referring to FIG. 4, after enclosing the torch body 2 with the wrapping layer 3, a fuel core 4, which is easily ignited, can be twirled on an upper end of the wrapping layer 3, extending from the torch body 2.
The entire periphery of torch body 2 after being enclosed by the wrapping layer 3 can be further surrounded in a radial direction with a combustible rope 51 to form into a heat resistant confining material 5. The rope 51 is combustible and is basically formed by twirling a cotton core, to constitute effects of adsorption and transient heat resistance by gaps between fibers of cotton core. From a heating up experiment of a thicker cotton rope, it is shown that the cotton rope is provided with a certain degree of heat resistance effect, due to that a lot of gaps are still remained in the rope, which will not easily conduct heat, and the pores inside the cotton core can adsorb the fuel liquid to increase the fuel content.
The rope 51 can also be made by rolling a piece or a strap of paper. By gaps formed in rolling the paper, the capillarity effect also exists to adsorb the molten liquid, or the same heat resistance effect as that provided by the cotton core can also be achieved if being subjected to an external thermal interaction. Basically, the rope 51 is made by a natural herb or wooden fiber, or is braided with threads of a natural casuarina. The application like a packthread is very suitable for the rope required by the present invention.
Referring to FIG. 5, the wind-proof torch 20 accomplished in FIG. 4 is provided with the igniting fuel core 4 at a top end, a complete winding is performed with the confining material 5 through the rope 51, and a supporting bowl 201 is located at a bottom of torch 20 to serve as a mechanical protection at the bottom of torch 20.
Referring to FIG. 6, after igniting the wind-proof torch 20 of the present invention, a flame 10 will be attacking toward the other side of torch 20, upon being acted by a pressing of sideways wind pressure F.
Referring to FIG. 7, by using the rope 51 which is wound on the outer circumferences of torch body 2, the flame 10 occurring at the top end will first touch the exterior of confining material 5 constructed by the combustible rope 51, which is provided with the capillarity effect, thereby having the function of transient heat resistance. Accordingly, the flame 10 will first touch the rope 51 and the interior of torch body 2 is prevented from being directly subjected to the hot melting effect through the isolation of rope 51, thereby enabling the torch 20 to achieve a function of wind-proofing.
Referring to FIG. 8, the torch 20 is ignited from its top end, and is burning transversally and then downward. By a protection of confining material 5 at the periphery of torch body 2 and a leak-proof function of wrapping layer 3, a full transient protection will be achieved to the outer circumferences of torch body 2. After igniting and forming the flame 10 at the top end, the fuel at top end will not be easily spreading out by a restriction of fiber yarns 21 due to the capillarity effect, a size of combustion part is reduced due to a consumption of fuel material, and a cracking between fibers is formed by a high temperature.
The rope 51 is wound on the outer circumferences of torch body 2, with one round next to the other, to form the confining material 5 and is provided with a gap 510 between neighboring ropes 51. The gap after burning will form into a cracking 510A which is generated by a reduction in size of rope 51 to yield to the cracking 510A after burning. The cracking 510A can provide oxygen A to flow in and the fiber yarns 21 are fractured into a plurality of sections with gaps by a high temperature carbonization. The plurality of gaps allow a hot molten fuel liquid 22 to be permeating into and form a restriction function, so as to keep the fuel liquid at the top position for burning.
Through the high temperature thermal interaction which is continual and is in a close proximity, the aforementioned rope 51 will form into a burning rope 51A which will become ashes and fall off automatically after accomplishing the carbonization, allowing the periphery at top end to be more in contact with oxygen for maintaining combustion.
Similarly, after accomplishing the carbonization, the fiber yarns 21 at top end surface also become the ashes to be driven by air flow. Therefore, the torch 20 of present invention can form a sequential combustion in a transversal direction, such that the combustion end is maintained at a transversal position and is then descending gradually. By using the transient heat resistance function of the plurality of fiber yarns 21 and the confining material 5, the fuel liquid can be kept at the top end, so as to satisfy a height requirement in complete combustion, and to reduce a waste of fuel liquid correspondingly.
The debris 211 and solid fuel 22 are mixed together in advance. Therefore, a hot melting effect will be formed when the solid fuel 22 is catalyzed by a thermal interaction with flame 10 at the top end of torch 20. The hot molten fuel liquid 220 formed will be spreading to a periphery due to an accumulation of mass, whereas most of the fuel liquid 220 will be moving up and vaporized. The residuals of carbonized debris 211 will be accumulated and floating on a surface of hot molten fuel liquid 220 to form a surface lamination. By an isolation of the lamination of debris 211, the thermal radiation wave of flame will be prevented from directly attacking the top end of torch body 2, thereby achieving the function of impeding the hot melting effect at the top end of torch body 2.
Following that, the carbonized debris 211 can form into an oxidized cracking through a sufficient catalyzing function of heat, and will be drifting with wind when they become the ashes. It is definitely that the carbonized debris 211 also exists in the lower interior of the torch body 2; therefore, the aforementioned working status of debris 211 is repeated.
Referring to FIG. 9, the interior of torch body 2 of present invention is made by mixing and solidifying the fiber yarns 21 and fuel 22. After enclosing the outer periphery of torch body 2 with the combustible wrapping layer 3, the outer periphery is protected by the confining material 5 which is made by winding and fastening the rope 51 circumferentially. By using the structure of present invention, the hot melting effect, which is generated after being subjected to a thermal interaction of the flame 10, will melt the fuel 22 on a horizontal surface at the top end to form the fuel liquid 220 which will be first protected by the wrapping layer 3 from dripping out. On the other hand, as the uppermost rope 51 is closest to the flame 10, it will be directly heated up and is identified as the burning rope 51A. As the burning rope 51A is provided with fibers, it will be carbonized and cracked after burning at a high temperature, thus generating a plurality of crack pores 511 at the top end of the wrapping layer 3. As the wrapping layer 3 is also a combustible fiber, it will be carbonized and cracked after being interacted in high temperature, forming a plurality of gaps for allowing a part of fuel liquid 220 to flow into and then to be adsorbed by the pores 511 of burning rope 51A to form a secondly adsorbed fuel liquid, such that the fuel liquid 220 can be vaporized and burning from the surface of wrapping layer 3. The capillarity effect formed can absorb the fuel liquid 220. Correspondingly, the burning rope 51A can still maintain its fixed shape temporarily by a viscosity of fuel liquid 220. However, when the fuel liquid 220 adsorbed by the uppermost burning rope 51A is completely burned out, the rope 51A will be completely carbonized and becoming the ashes. As the second rope 51 in a neighborhood is made by a fiber material, it is provided with fibered capillaries 512 itself. However, a part of the fuel liquid which is spreading out from the aforementioned cracked wrapping layer 3 will be dropped into the neighboring rope 51 and be adsorbed by the function of its fibered capillaries 512, which will be identified as a first adsorption operation, other than the part being adsorbed by the burning rope 51A. Of course, the amount of adsorption is the remaining of the pre-adsorption of the burning rope 51A; therefore, it is very scarce. In addition, the wrapping layer 3 is provided with a certain amount of mechanical intensity for protection under a condition of not being burned; therefore, the fuel liquid will not drip out, allowing other ropes 51 to be close to a dry state. Accordingly, under an action of wind pressure as shown in FIG. 7, the ropes at outer periphery will not be ignited immediately. The fiber yarns 21 at the top end of torch body 2 are, in the same way as that shown in FIG. 8, to keep restricting the fuel liquid 220 and to perform a complete carbonization.
A triangular corner space 500 is formed at an outer surface of wrapping layer 3 between the outer circumferences of neighboring ropes 51, next to the outer circumference of torch body 2. The corner space 500 will form a function of isolation; therefore, under the condition of sideways attack of flame as shown in FIG. 7, a larger space can be formed by the corner space 500 to impede a path of heat transportation, thereby constituting a thermal insulation to the outer circumference of torch body 2. Basically, the rope 51 is a material with the heat resistance effect, such as a cotton rope or a rope made by rolling a piece of paper, or a packthread constituted with threads of casuarina; they can all be suitable for the rope 51 of present invention.
Referring to FIG. 10, after connecting with a modular handling bar at its bottom end, the wind-proof torch 20 of present invention can be installed on a ground in an upright position, or be carried during moving. The handling bar 6 is a multi-sectional device, including handling bars 6A, 6B which can be sheathed together. Using a multi-sectional assembling, a height of torch 20 from the ground can be increased, or the torch 20 can be supported with the single handling bar 6A or 6B independently, so as to lower the height of torch 20 from the ground. In addition, by connecting the torch 20 with a male end 61 of handling bar 6, the torch 20 can be independently emplaced above other object or even be directly emplaced on the ground, thereby achieving a multipurpose function. A female end 62 of the handling bar 6 is connected to a sheathing tube 621 which can be connected with a male end 61 of another handling bar, and can be further connected with a standing pole 7. The standing pole 7 is a rod whose top end forms into a connection end 71 to be assembled inside the sheathing tube 621, and whose waist position is linked to a grounding end 74 with a transversal rod 76 which can be linked to the grounding end 74 in a protruded shape through a straight rod 72 or can be directly linked to a slant rod 73 for connecting with the grounding end 74. Basically, the connection end 71 and the grounding end 74 are on a same axis, and a handle 75 for holding by hands is formed at the waist part due to an extension of the transversal rod 76. The handle 75 provides for handling by hands upon pulling up the standing pole 7. When the handling bar 6 connected with the standing pole 7 is inserted on the ground, the standing pole 7 can be drilled into the ground to put the handling bar 6 in an upright position. On the other hand, the handling bar 6 can be first disassembled and then the handle 75 installed at the standing pole 7 can be held by a user to pull up the standing pole 7, upon pulling up the torch.
As the standing pole 7 is connected with the grounding end 74 with the transversal rod 76, the straight rod 72, and the slant rod 73, a configuration of multiple bending points is formed at the waist part. In addition, as the grounding end 74 is fixed by the ground surface, and the connection end 71 is connected to the handling bar 6, when the handling bar 6 is subjected to an action of external force, an external stress will be absorbed through the multiple bending points near the handle 75, and a stress transmitted from the handling bar 6 will be offset through an absorption of transversal rod 76, straight rod 72, or slant rod. The external force can be a wind pressure or a man-made touch.
A change part 70 is formed by bending down the connection end 71 and is connected to the grounding end 74. When the connection end 7 is subjected to a swing of external force, a stress of variation can be provided to the connection end 7 through the change part 70. In addition, the handle 75, which is formed by using the change part 70, forms a hand-hole for a user, and facilitates a holding of transversal rod 76 with hands to easily pull up the standing pole 7.
Referring to FIG. 11, basically the handling bar 6 is composed of a plurality of rods 60A, 60B, 60C which are bundled together, with a connection rod 611 assembled at a center position of male end 61, and the sheathing tube 621 assembled at a center position of female end 62. It is in a shape of bundle after assembling a plurality of rods 60.
Referring to FIG. 12, the plurality of rods 60A, 60B, 60C are aligned radially by an equal angle, with the connection rod 611 or sheathing tube 621 assembled at their center position.
Referring to FIG. 13, a front end and a rear end of the plurality of rods 60A, 60B, 60C, are aligned in an interleaved manner. For example, the angular positions of rods 60A, 60B, 60C, at the position of male end 61, can be shown in the end view of FIG. 14; whereas, as shown in FIG. 15, the rod 60A is interleaved with the rod 60B in FIG. 14, and the rod 60C is interleaved with the rod 60A in FIG. 14, at the position of female end 62, and a slant relation is formed by a rotation in same direction against their lines of axis, such that the rods at two ends of handling bar 6 are aligned in an interleaved manner, in order to acquire a slant stress for impeding a torsion.
In principle, the degree of interleaving at the front and rear ends of rods 60A, 60B, 60C is about 120 degrees. However, according to a condition in manufacturing a material, it can be less than or greater than 120 degrees. As the present invention is to achieve a slant relation to acquire a slant distribution of stress, in order to increase a tolerance to pressure and an elastic energy; therefore, it can achieve the object of requirement at long as there is the slant relation.
The torsion among the aforementioned rods 60A, 60B, 60C is primarily to form a slant distribution against their lines of axis. For example, after assembling three straight rods to a parallel bundle in 120 degrees, torsion is implemented to the front and rear ends to change their relative positions to be in a slant direction. The principle of change is that the torsion stress cannot exist and only an interrelationship in the slant direction can be available.
Referring to FIG. 16, after making each rod 60 to be distributed in a slant and interleaved manner as shown in FIG. 13, they are fastened with a wire 64 at the positions of male end 61 and female end 62, and the waist part is also fastened with the wire 64. By fastening the front and rear ends and the waist part with the wire 64, and by the fact that each rod 60A, 60B, 60C is against each other at its outer circumferences, a movable status will be formed at unfastened positions. In bending the handling bar 6 through the movable status, the change of curvature generated from bending can be absorbed, so as to generate elastic strain energy. The rod 60 is made by an elastic material, such as a limb of straight plant which can be a vine, a bamboo or a straight stem.
The wire 64 can be made by any wiring material or iron thread. In order to acquire a larger elastic energy, a natural vine can be chosen.
Referring to FIG. 17, after aligning each rod 60A, 60B, 60C by a radial line R with an identical angle, and assembling the connection rod 611 and sheathing tube 621 at their center, the wire 64 is used to fasten the outer circumferences. The wire 64 can pass around an entire inner circumference, such that an intersection point P will be located at the position of radial line R. As the wire 64 is made by a material which is provided with elasticity and is easy to warp, each rod can generate a proper tension to be acting on the position pointed by the radial line R, after fastening each rod 60A, 60B, 60C. For example, the rod 60C can be offset with the center of sheathing tube 621 according to the linear orientation of radial line R. The offset rod 60C is under an action of a strong external force to be offset with the sheathing tube 61 in outer circumferences. As the wire 64 is provided with a capability of elastic contraction, it can provide a proper tension to enable the rod 60C to generate an offset action. Following that, the elasticity of wire 64 will contract the rod 60C inward.
Referring to FIG. 18, each rod 60A, 60B, 60C is aligned by a radial line R with an identical angle, the connection rod 611 or the sheathing tube 621 is assembled at their center, and their outer circumferences are fastened with the wire 64 which can simultaneously wind two outer circumferences, such that the intersection point P of wire 64 will be located at a position one half of the included angle of radial line R. As the wire 64 is made by a plant such as a vine which is provided with elasticity, after simultaneously winding two outer circumferences (the connection rod 611 plus the rod 60A, or the connection rod 611 plus the rod 60B) with the wire 64, and winding each rod 60A, 60B, 60C along with the connection rod 611 or the sheathing tube 621, the intersection point of wire 64 will be surely located at the center position of angle of radial line R. Therefore, when one of the rods is subjected to an external force, it will also generate an elastic offset to absorb the external force. By the assembling methods as shown in FIG. 13, FIG. 17, or FIG. 18, the handling bar can have a better elasticity. Basically, a natural plant can be chosen as a raw material of the handling bar, which will evolve into a primitive mood and will be complied with environmental regulations.
After accomplishing the aforementioned handling bar, a waterproof layer can be further coated on its outer surface to achieve a waterproof effect and to avoid fast erosion. In addition, by an interaction with the waterproof layer, the handling bar can be fastened more tightly. The waterproof layer can be best made by an elastic waterproof material.
The present invention is basically a wind-proof torch, which use the confining material to impede the heat and the fiber yarns inside the torch body to restrict the fuel, so as to achieve a wind-proof effect, allow a full oxidation of the fuel liquid, maintain a transversally descending at the burning end, and achieve a portability by connecting the bottom end of torch with the modular handling bar or put the torch in an upright position by connecting the bottom end of torch with the standing pole. In addition, the handling bar is provided with elasticity; therefore, it can absorb the external force to prevent the torch from being damaged by forming a mechanical force, which is a brand new invention in the area of lightening torch used in outdoor camping
