Description

  The present invention mainly relates to a candle that can be suitably used as an emergency light in the event of a disaster such as an earthquake, tsunami, or typhoon. Furthermore, the present invention can be configured as a candle that is lit for a long time and lit for 100 hours, for example.

  Lamps using dry batteries are often used as emergency lights before electricity is restored in the event of a disaster, but dry batteries may discharge if left for a long time and may not be used in an emergency. In addition, regular maintenance is required, which is laborious and costly and cannot be stocked. On the other hand, there is an engine type, but expensive and long-term storage maintenance is difficult.

  On the other hand, candles have no deterioration due to storage, and can be used reliably with an ignition device such as a match or lighter, so they are highly reliable as emergency lights. Therefore, in order to secure a certain burning time, a large candle of about 20 to 40 cm in length is used for disasters, but such a thing is also made only of a brazing material and cannot be excessively thickened. The use time is limited to about 10 hours. Moreover, since the flame is exposed, it may be inadvertently contacted with the flame and burned, and there is a risk of burning it into a combustible material and causing a fire, and the flame is easily extinguished by wind. In addition, the wax melted during the combustion hangs down along the side of the candle, solidifies at the bottom, and remains as a residue after the combustion. There was a problem.

  Therefore, as shown in FIG. 9A, a candle d is proposed in which a bottomed cylindrical container a such as glass or heat-resistant plastic is filled with a wax b and a core c is provided at the center thereof ( For example, see Patent Document 1.) In the candle d, since the flame f burns inside the container a, the container a serves as a guard, reducing the risk of being burned or burning into the surrounding combustibles, and when used outdoors. Since the container a serves as a windshield, the flickering of the light and the blow-out due to the wind are eliminated. Furthermore, the molten wax does not become a residue and does not contaminate the surrounding floor surface, and therefore it is not necessary to remove the residue.

JP-A-11-228987

  However, the container a of the candle d is slippery because it uses a relatively hard material such as glass or plastic. As shown in FIG. 9B, when the container is used on a mounting table t such as a desk, it is used. If it is accidentally dropped and damaged, and if it is still burning, the flame may spread and cause a fire. Moreover, aftershocks often occur in the event of an earthquake disaster, and there is a high risk that a candle d will fall due to severe shaking and will burn into combustible materials such as paper and cloth, causing a fire. In particular, 100-hour candles that are continuously lit for a long time have a large possibility of a fire or a fall because of their large size, and stable installation is strongly required for safety.

  The problem of the present invention is to solve the problems of the candles described above, so that they will not accidentally fall off a table such as a desk, and will not fall over even if a strong shake such as an aftershock occurs. It is to provide a candle that does not break with extremely low risk.

  In order to achieve the object, the invention according to claim 1 is a candle in which a burning brazing material is housed in a container in which an outer peripheral wall portion is raised on a mounting base portion and only an upper end is opened. And the adsorber which adsorb | sucks the mounting surface in which this pedestal part is mounted in an airtight inside is provided in the said pedestal part.

In the invention according to claim 1 , the adsorber has an insertion hole through which the pedestal portion passes and passes through the upper surface of the pedestal portion and the placement surface on which the pedestal portion is placed, and is airtightly forward. It consists of the adsorption sheet which has the cyclic | annular and elasticity mounted in the description mounting surface .

The invention of claim 2, wherein the base unit, characterized in that it comprises a conical portion which is a side surface inclined.

The invention according to claim 3, wherein the adsorbent sheets are you characterized by comprising a rubber or a thermoplastic elastomer.

  Since the present invention is configured as described above, the pedestal is strongly fixed to the placement surface by the suction tool being attracted to the placement surface, so that the container can be placed even if severe shaking such as aftershock occurs. There is no skidding or tipping over the surface. Therefore, it is possible to prevent the candle from becoming unusable due to breakage of the container, etc., and it is possible to prevent the occurrence of fire or burns due to the flame burning into the combustible material. In addition, since the installation stability required for a 100 hour lighting candle is ensured, it can be used safely as an emergency light in a disaster.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view illustrating an embodiment of the present invention, FIG. 2 is a perspective view of an adsorbing sheet, and FIGS. 3A and 3B are cross-sectional views illustrating an adsorbing procedure. The candle 1 of the present invention includes a container 4, an adsorbing tool 6, and a brazing material W. The container 4 includes a pedestal portion 2 and a cylindrical outer peripheral wall portion 3 rising from the pedestal portion 2, and only the upper end is open. In this embodiment, the outer peripheral wall portion 3 has a downward bulging shape, and thus has a structure in which the center of gravity is low and is not easily toppled.

  The outer peripheral wall 3 is constituted by a translucent portion 21 using a translucent material such as translucent glass or heat-resistant plastic in order to transmit the light of the flame. In this embodiment, as shown in FIGS. 1 and 4, all of the outer peripheral wall portion 3 is configured by the light transmitting portion 21 by forming the entire container 4 including the base portion 2 from the light transmitting glass. The periphery of the opening 22 at the upper end of the outer peripheral wall 3 or the lower end may be made of a non-light-transmitting material such as stainless steel, aluminum, other metals, or ceramics.

  The translucent part 21 is provided with uneven patterns 23 of various shapes on the outer peripheral surface thereof. When the light emitted from the flame F passes through the uneven pattern 23, the direction of the light is dispersed by being bent, so that the glare of the flame can be reduced and a wide angle can be illuminated. In the present embodiment, the concavo-convex pattern 23 is constituted by a horizontal stripe 24 having a cross-sectional arc having a radius of about 4 to 10 mm and continuous in a wavy shape in multiple stages. The horizontal stripes 24 are formed of translucent glass and have a circular arc in cross section, so that each horizontal stripe 24 forms a belt-like convex lens. Accordingly, the light transmitted through the translucent part 21 is dispersed and bent in the vertical direction in each horizontal stripe 24, so that the light of the flame F is diffused throughout the translucent part 21 to reduce glare, and with respect to the vertical direction. Can illuminate a wide angle.

  The pedestal portion 2 is provided at the lower portion of the outer peripheral wall portion 3, and the bottom surface thereof is formed to be horizontal and flat in order to stably place the container 4 on the placement surface 5. The pedestal portion 2 of the present embodiment includes a conical portion 8 that is inclined upward in a state in which the side surface protrudes outward as compared with the upper surface. In addition to this, the pedestal portion 2 may have various shapes such as a columnar shape having a smaller diameter than the outer diameter of the outer peripheral wall portion 3 or a horizontal circular base integrally provided at the lower portion of the columnar body. it can. In addition, the pedestal portion 2 of this embodiment is integrally formed of transparent glass including the outer peripheral wall portion 3, but the pedestal portion 2 made of a separate part can be attached by screws, adhesion, welding, or the like. Further, the pedestal 2 can be formed by combining a plurality of parts.

  As shown in FIG. 2, the suction tool 6 is composed of a suction sheet S having elasticity. In this embodiment, the suction sheet S is circular, but may be elliptical or polygonal. Further, the suction sheet S is formed in an annular shape with an insertion hole 7 through which the pedestal portion 2 passes substantially in the center. The insertion hole 7 is formed in accordance with the shape of the pedestal portion 2. In this embodiment, the insertion hole 7 is formed in a circular hole according to the conical pedestal portion 2, but may be formed in a square hole, an elliptical hole, or the like.

  The suction sheet S is formed to a thickness of about 2.5 to 5.0 mm, preferably about 2.7 to 3.0 mm, and in this embodiment, 3.0 mm. If the thickness is less than 2.5 mm, the adsorbing force is insufficient, so that the candle 1 easily slips or falls, and if it exceeds 5.0 mm, it becomes hard to adsorb inside airtightly. The suction sheet S is formed to have a diameter of about 95 to 140 mm, preferably about 115 to 125 mm, and 120 mm in this embodiment. If the diameter is less than 95 mm, the adsorbing power is insufficient, so that the candle 1 easily slides or falls, and if it exceeds 140 mm, the adsorbing sheet S becomes unnecessarily large and the candle 1 is difficult to carry. The handling becomes inconvenient, such as requiring a large mounting surface 5.

  The size of the insertion hole 7 is 48 to 72%, preferably 64 to 68%, compared to the outer diameter of the pedestal 2. If it is less than 48%, the pedestal portion 2 passes through, and when the insertion hole 7 expands against the elasticity of the suction sheet S, the expansion ratio becomes excessive, which makes handling difficult and from the inner edge of the insertion hole 7 There is a possibility of breakage, and if it exceeds 72%, there is a possibility that it will come off the pedestal 2. The pedestal portion 2 of this embodiment has an outer diameter of 76 mm, and an insertion hole 7 with a diameter of 50 mm is formed.

  The adsorbing sheet S is made of rubber or a thermoplastic elastomer. As rubber, synthetic rubber such as styrene-butadiene rubber, chloroprene rubber, butyl rubber, isoprene rubber, urethane rubber, acrylic rubber, ethylene propylene rubber, and natural rubber can be used, and two or more kinds of rubbers are used in combination. You can also. As the thermoplastic elastomer, olefin elastomer, styrene elastomer, ester elastomer, urethane elastomer, amide elastomer, vinyl chloride elastomer, and the like can be used. Further, the adsorbing sheet S may be a sponge body having single bubbles formed by adding a foaming agent to the material.

  In addition, it is preferable that the stretchable cover layer 25 is integrally laminated on the suction sheet S in that the surface of the suction sheet S can be damaged and protected from heat, and an arbitrary coloring and pattern can be added. The cover layer 25 is made of stretchable woven material such as nylon, rayon, cotton, polyethylene, polypropylene, and acrylic.

  3A, when the pedestal 2 is press-fitted into the insertion hole 7 of the suction sheet S, the pedestal 2 passes through the insertion hole 7 due to elastic deformation of the suction sheet S, and the suction sheet S is deformed into a trumpet shape extending downward along the inclined surface of the conical portion 8 and is fixed to the conical portion 8 by elasticity. At this time, the edge of the insertion hole 7 of the suction sheet S is supported by contact with the receiving portion 38 at the lower end of the outer peripheral wall 3 of the container 4. The suction sheet S supported at the edge of the insertion hole 7 by the receiving portion 38 is prevented from returning to the original state where the insertion hole 7 is expanded against the elasticity, and maintains an elastic force. 8 is stably fixed.

  Next, as shown in FIG. 3B, when the candle 1 is lowered toward the placement surface 5, the outer edge portion of the suction sheet S elastically deformed in the trumpet shape is pressed from the placement surface 5 and the placement surface 5 is pressed. The surface 5 is pushed outward and spreads. Thereby, the said suction sheet S straddles the base part upper surface 2U which consists of the inclined surface of the cone-shaped part 8 side, and the mounting surface 5, and is pressed toward the mounting surface 5 by the elasticity of the suction sheet S. Therefore, the adsorption sheet S is adsorbed to the placement surface 5 by being placed on the placement surface 5 while maintaining an internal airtight state. (In this specification, the upper surface 2U of the pedestal portion includes an upward inclined surface formed on the side surface of the pedestal portion 2.) Accordingly, when the hand is accidentally hit or an aftershock occurs, the candle 1 is unexpectedly moved. Even when a large lateral force is applied, the container 4 is firmly fixed to the placement surface 5 by the suction sheet S, so that the candle 1 does not cause a side slip or a tipping moment, and the container 4 is damaged. It is possible to prevent the lighting from being disabled, the occurrence of a fire, and a burn. Further, in this embodiment, since the pedestal portion 2 includes the conical portion 8, the suction sheet S attached to the pedestal portion 2 has a trumpet shape along the inclined surface of the conical portion 8, and this is placed on the mounting surface. When placed on 5, it is strongly adhered to the placement surface 5 due to its elasticity, so that the reliability of the suction fixation is high and the handleability is excellent.

The container 4 has a volume of 650 to 900 cm ³ and stores the brazing material W therein. The 650cm less than ^3, even using most of the brazing material W in the combustion, it is not possible to obtain a total burn time of 100 hours, insufficient lighting time as candles for disaster exceeds 900 cm ^3, the total weight Is too heavy and inconvenient to carry.

  As shown in FIG. 4, the brazing material W includes an intermediate brazing material Wi disposed in the center of the inside of the container 4, and an outer brazing material Wo filled between the intermediate brazing material Wi and the inner surface of the container 4. It consists of. The brazing filler metal Wi has a cylindrical shape, and a separately produced one is inserted from the opening 22 of the container 4. On the other hand, the outer brazing material Wo is formed by injecting a molten brazing material between the intermediate brazing material Wi and the outer peripheral wall portion 3 and then cooling. In this example, the outer brazing material Wo has a downward bulging shape along the shape of the container 4. Yes.

  The melting point of the brazing filler metal Wi is set to, for example, about 55 to 70 ° C., and the melting point of the outer brazing filler metal Wo is set to be lower than that of the brazing filler metal Wi, for example, about 40 to 60 ° C. For this reason, since it is far from the flame F, the amount of heat transmitted is small, and heat is easily taken away to the outside through the outer peripheral wall portion 3, so that thermal melting of the outer brazing material Wo, which is lower in temperature than the middle brazing material Wi, is promoted. The upper surfaces of the brazing material Wi and the outer brazing material Wo are substantially at the same height. Further, as indicated by the phantom line in FIG. 4, the thermal melting of the outer brazing material Wo is delayed, so that the position of the outer brazing material Wo on the inner surface of the container 4 and the lowest position around the core material 26 of the middle brazing material Wi Even if a level difference h occurs, the level difference h is suppressed to 1/10 or less of the inner diameter d of the container 4 at that height and to 1/3 or less of the flame height. Therefore, the light of the flame F can be brightly illuminated without being blocked by the outer brazing material Wo. Moreover, since most of the brazing material W including the outer brazing material Wo is melted and burned, the lighting time can be maintained long without losing the brazing material W. The specific melting points of the brazing filler metal Wi and the outer brazing filler metal Wo are appropriately set according to conditions such as the temperature conditions used, the outer brazing filler metal Wo, and the size of the brazing filler metal Wi.

  The core material 26 is erected substantially at the center of the brazing filler metal Wi, has a length from the upper end to the lower end, and is composed of natural plant fibers such as cotton and hemp yarn, and regenerated cellulosic fibers such as rayon. A material or form having a capillary action that sucks up molten wax, such as paper, cloth, thread, or string, is used. In order to obtain sufficient brightness, a flame having a height of about 15 to 25 mm is required. Therefore, the core material 26 can always be kept up from the melting surface M of the brazing material W, for example, about 5 to 10 mm. Therefore, it is necessary to use a core material 26 of sufficient thickness and material for a 100-hour candle that lasts for a long time. When the core material 26 of 100% cotton is used, the burning time is stabilized, and by adding Tegs into the fibers, the shape retention and durability of the core material 26 can be improved. By inserting a wire in the center of the core, the core material 26 can be prevented from being broken in the middle, and the continuous lighting is not interrupted.

  As shown in FIG. 5, the container 4 includes a substantially disk-shaped lid body 28 having a spherical portion 27 whose center swells upward, and the lid body 28 is provided at the upper end of the outer peripheral wall portion 3. It is mounted on the opening edge part 29 which spreads in a trumpet shape. The lid body 28 has a long hole-like intake port 30 provided in a plurality at the peripheral flange portion and a circular hole-like exhaust port 31 provided at the central top portion of the spherical surface portion 27. As shown in FIG. 4, the intake port 30 and the exhaust port 31 ventilate the opening 22 of the container 4, and the external air A <b> 1 entering the inside of the container 4 from each intake port 30 extends along the inner surface of the outer peripheral wall 3. The oxygen A is supplied to the flame F by being lowered, and the burned air A2 used for the combustion of the flame F is heated to a high temperature, and thus rises as it is in the center of the opening 22 and is discharged from the exhaust port 31 to the outside. . In this way, the cover 28 forms a ventilation path that smoothly flows without disturbing the air for combustion, so that the flame F does not fluctuate or flicker, and stable combustion can be obtained.

  The container 4 can be carried with a movement fitting 32 attached thereto. As shown in FIG. 6, the candle moving bracket 32 is rotatable to a substantially annular ring portion 34 having a slightly smaller diameter than the maximum outer diameter of the bulged portion 33 of the outer peripheral wall portion 3, and the ring portion 34. The ring portion 34 and the suspension portion 35 are formed by bending a wire. The ring part 34 has four protrusions 34a that are bent outwardly in a V-shape. Each of the suspension portions 35 has a U-shaped knob portion 35b formed by bending the upper ends of a pair of gently curved vertical portions 35a, 35a outward and connecting the tips thereof. The lower portions of the vertical portions 35a, 35a are wound around the tip of the projection 34a of the ring portion 34 by one rotation and extend outward, and the tips are connected to each other by a circular arc portion 35c that is substantially concentric with the ring portion 34. Yes.

  Further, as shown in FIG. 7, when the candle moving bracket 32 is inserted into the container 4 from below, the ring portion 34 is locked to the horizontal stripes 24 having an outer diameter slightly larger than the diameter of the ring portion 34. Mounted on the container 4. The candle-moving metal fitting 32 attached to the container 4 can be lifted without being touched directly by supporting the knobs 35b, 35b of the hanging parts 35, 35 with both hands. The candle 1 can be moved safely and in a horizontal state without being burned by the container 4 formed. The arc portion 35c rotates around the winding portion of the projecting portion 35a in conjunction with the movement of the integrally formed hanging portion 35 falling to the outside by its own weight when the knob portion 35b is released. The suspension part 35 is maintained at a predetermined angle by coming into contact with the outer peripheral wall part 3.

  A candle 1 shown in FIG. 8 shows a different embodiment, and includes a substantially cylindrical outer peripheral wall portion 3, and includes a substantially disc-shaped bottom plate 36 and a leg portion 37 erected substantially at the center of the bottom plate 36. A pedestal 2 is provided. An annular suction sheet S straddling the pedestal part upper surface 2U formed by the upper surface of the bottom plate 36 of the pedestal part 2 and the placement surface 5 is placed on the placement surface 5 in an airtight manner, whereby the pedestal part 2 is It is fixed to the mounting surface 5.
