Description

  The present invention relates to a lighter. More specifically, the present invention relates to a technical field in which a lock member and a lock release lever are provided to restrict the rotation operation of the operation cap with respect to the main body to improve safety.

  There are lighters mainly used to light cigarettes.

  In the lighter, the required parts such as a nozzle, a frame cover that covers the nozzle, and an operation cap that functions as an operation unit at the time of ignition are arranged above the case body in which liquefied fuel is sealed. In some cases, the fuel ejected from the nozzle is ignited by rotating in a predetermined direction with respect to the case body (see, for example, Patent Document 1).

  An example of such a conventional lighter is shown below (see FIGS. 9 and 10).

  The lighter a has a vertically long case body b, and liquefied fuel is sealed in the case body b. An ignition means (not shown) is disposed inside the case body b.

  A nozzle c that extends vertically is disposed on one end of the case body b. Below the nozzle c, a valve mechanism and a fuel pipe (not shown) are arranged inside the case body b.

  An adjustment knob d for adjusting the heating power is supported on one end side of the upper portion of the case body b.

  An operation cap e is rotatably supported on the upper portion of the case body b. The operation cap e has an operation portion f that is operated at the time of ignition, a closing portion g that closes the upper side of the nozzle c, and supported arms h and h that protrude substantially downward from the operation portion f. The lower ends of h and h are rotatably supported by the case body b.

  A frame cover i that covers the nozzle c is attached to the upper portion of the case body b. In the frame cover i, a crater j penetrating vertically is formed in the upper surface portion, and air holes k, k, k are formed in the peripheral surface portion.

  In the lighter a configured as described above, when the operation portion f is pressed downward and the operation cap e is rotated in a predetermined direction with respect to the case body b as shown in FIG. The fuel supply path is opened, and the liquefied fuel is vaporized and ejected from the nozzle c as a fuel gas through the fuel pipe. At the same time, when the operation cap e is rotated, the ignition means disposed inside the case body b is operated to ignite the fuel gas ejected from the nozzle c.

  The ignited fuel gas is burned in the vicinity of the crater j of the frame cover i so that the flame extends upward from the crater j.

  When the downward pressing on the operation portion f is released, the operation cap e is rotated in the opposite direction to the case body b by a biasing means (not shown) (see FIG. 9), and the fuel supply path is opened by the valve mechanism. The fuel gas is blocked from being ejected from the nozzle c, and the fire is extinguished.

  The operation cap e returns to the original position where the crater j of the frame cover i is closed from above.

  However, in the above-described conventional lighter a, ignition is performed only by pressing the operation portion f downward and rotating the operation cap e in a predetermined direction with respect to the case body b. Therefore, when the lighter a is gripped, the operation part f may be accidentally pressed downward, the operation cap e may be rotated, and ignition may be performed, which impairs safety.

  In particular, when a child or a young person grips the lighter a, if the operation portion f is pressed downward and the operation cap e is rotated, safety for the child or the young cannot be ensured.

  Therefore, an object of the lighter of the present invention is to overcome the above-described problems and improve safety.

  In order to solve the above-described problems, the lighter has a main body having a case body in which fuel is sealed, an operation cap rotatably supported by the main body, and the operation cap operated in one direction. The fuel is ignited by rotating in a predetermined direction, and a nozzle for ejecting the fuel to the outside when the operation cap is operated in the one direction and rotated in the predetermined direction, a lock hole, and an ignition A frame cover having a crater through which the lit flame is ejected and covering the nozzle; and inserted into a lock hole of the frame cover to restrict the rotation of the operation cap in the predetermined direction with respect to the main body. The operation is performed between a lock position and a non-lock position that is pulled out from the lock hole of the frame cover and allows the operation cap to rotate in the predetermined direction with respect to the main body. A lock member that is movably supported by the cap and has an actuated portion; a lock spring that biases the lock member toward the lock position; and a slidable portion on the actuated portion of the lock member. The working part has an action part and the action part slides on the actuated part to move the lock member to the unlocked position and a holding position for holding the lock member in the lock position. And a lock release lever supported movably on the operation cap.

  Therefore, in the lighter, the lock release lever is moved from the holding position to the lock release position, the lock member is moved from the lock position to the unlock position, the lock on the operation cap body is released, and the operation cap body is released. It can be turned.

  In the lighter described above, it is desirable that the one direction for operating the operation cap and the direction from the holding position of the lock release lever toward the lock release position are different.

  By making the direction in which the operation cap is operated different from the direction from the holding position of the unlocking lever toward the unlocking position, the operating cap moves relative to the case body while the unlocking lever is held at the holding position. It is difficult to rotate.

  In the lighter described above, it is desirable that the one direction for operating the operation cap and the direction from the holding position of the lock release lever toward the lock release position are orthogonal to each other.

  By setting the one direction for operating the operation cap and the direction from the holding position of the unlocking lever to the unlocking position to be orthogonal, the operating cap is attached to the case body while the unlocking lever is held at the holding position. It is not rotated with respect to it.

  In the above-described lighter, it is desirable to provide a biasing spring that biases the lock release lever toward the holding position.

  By providing a biasing spring that biases the lock release lever toward the holding position, the lock release lever is held at the holding position by the biasing force of the biasing spring when the lock release lever is not operated.

  In the above-described lighter, the action portion of the lock release lever is formed with a sliding inclined surface that can slide with the action portion of the lock member, and the action portion of the lock member is acted on the action portion of the lock release lever. It is desirable that the urging force of the locking spring is transmitted through the portion so that the lock release lever is urged toward the holding position.

  The urging force of the locking spring is transmitted to the action part of the unlocking lever so that the unlocking lever is biased toward the holding position, so that the unlocking lever can be operated when the unlocking lever is not operated. It is held at the holding position by the urging force of the locking spring.

  The lighter according to the present invention includes a main body having a case body in which fuel is sealed, an operation cap rotatably supported by the main body, and the operation cap rotated in one direction to rotate in a predetermined direction. A lighter for igniting the fuel, and a nozzle that ejects the fuel to the outside when the operation cap is operated in the one direction and rotated in the predetermined direction; A frame cover that covers the nozzle, and a lock position that is inserted into a lock hole of the frame cover and restricts rotation of the operation cap in the predetermined direction with respect to the main body. The operation cap is pulled between the operation cover and a non-lock position that is pulled out of the lock hole of the frame cover and allows the operation cap to rotate in the predetermined direction with respect to the main body. A lock member that is movably supported and has an actuated portion, a lock spring that biases the lock member toward the lock position, and an action that is slidable on the actuated portion of the lock member And the operation portion between an unlock position for moving the lock member to the unlock position and a holding position for holding the lock member at the lock position. And a lock release lever supported movably on the cap.

  Therefore, if the lock release lever is not operated to release the lock, the operation cap cannot be rotated with respect to the case body to perform ignition, so that the operation cap is rotated accidentally and ignition is performed. Therefore, safety can be improved.

  In particular, it is possible to prevent the operation cap from being turned when a child or a young person grips the lighter, and safety for the child or the young can be ensured.

  In the invention described in claim 2, the one direction for operating the operation cap is different from the direction from the holding position of the lock release lever toward the lock release position.

  Accordingly, when the operation cap is operated in a state where the lock release lever is held at the holding position, the lock release lever is hardly operated, and erroneous operation can be prevented.

  In the invention described in claim 3, the one direction in which the operation cap is operated and the direction from the holding position of the lock release lever toward the lock release position are orthogonal to each other.

  Therefore, when the operation cap is operated while the lock release lever is held at the holding position, the lock release lever is not operated, and erroneous operation can be reliably prevented.

  According to a fourth aspect of the present invention, a biasing spring that biases the lock release lever toward the holding position is provided.

  Therefore, the lock release lever is securely held at the holding position when no operation is performed on the lock release lever, and further safety can be improved.

  In the invention described in claim 5, a sliding inclined surface that is slidable with the operated portion of the lock member is formed in the action portion of the lock release lever, and the action portion of the lock release lever is formed. The urging force of the locking spring is transmitted through the acted portion of the lock member so that the lock release lever is urged toward the holding position.

  Therefore, a dedicated spring member for urging the lock release lever is not required, and the number of parts can be reduced and the mechanism can be simplified.

The lock member 16 is movable between a locked position, which is a lower moving end, and an unlocked position, which is an upper moving end, and the protrusion 18 and the actuated parts 19, 19 are formed on the bottom surface of the support recess 8. It is held in the locked position in the contact state. The movement of the lock member 16 in the front-rear direction is restricted by the restriction walls 9, 10 provided in the support recess 8, and the rear edge of the protrusion 18 is positioned close to the rear restriction wall 10, thereby Rotation in is regulated.

  A lock release lever 20 is supported by the support recess 8 so as to be movable in the front-rear direction. The lock release lever 20 is formed by integrally forming a base portion 21, an operation protrusion 22 protruding upward from the base portion 21, and action portions 23, 23 protruding forward from the base portion 21, respectively (FIG. 3). And FIG. 5).

  A spring receiving projection 21 a that protrudes downward is provided at the rear end of the base portion 21.

  The upper surface of the operation protrusion 22 is formed as an uneven portion 22a.

  The action portions 23 and 23 are spaced apart from each other on the left and right, and have sliding inclined surfaces 23a and 23a that are inclined so as to be displaced downward as they go forward at the front end portions.

  The unlocking lever 20 has the action portions 23 and 23 positioned on the outer sides of the regulating walls 9 and 10, respectively, between the holding position as the rear moving end and the unlocking position as the front moving end. It can be moved. The lock release lever 20 is positioned in a state where the sliding inclined surfaces 23a and 23a of the operating portions 23 and 23 are in contact with the sliding arc surfaces 19a and 19a of the operated portions 19 and 19 of the lock member 16, respectively. (See FIG. 5).

  In a state where the lock release lever 20 is supported by the support recess 8, the biasing spring 24 is supported between the spring support protrusion 12 and the spring receiving protrusion 21 a of the lock release lever 20. The urging spring 24 is, for example, a compression coil spring, and the urging spring 24 urges the lock release lever 20 toward the holding position.

  In a state where the lock member 16 and the lock release lever 20 are supported by the support recess 8, a substantially flat cap cover 25 facing the vertical direction is attached to the cover 6 (see FIGS. 3 to 5).

  The cap cover 25 is formed with pressed recesses 25a and 25a at both left and right ends at a position near the front end of the upper surface, and the pressed recesses 25a and 25a are opened upward and outward.

  At a position near the front end on the lower surface of the cap cover 25, a spring receiving recess 25b opened downward is formed.

  On the rear end side of the lower surface of the cap cover 25, a moving concave portion 25c opened downward is formed. An arrangement hole 25d penetrating vertically is formed on the rear end side of the cap cover 25, and the arrangement hole 25d communicates with the movement recess 25c. The arrangement hole 25d is formed long in the front-rear direction.

  The cap cover 25 is attached to the cover 6 so as to cover the support recess 8 from above, and is fitted into the support recess 8. In a state where the cap cover 25 is attached to the cover 6, the outer peripheral portion of the lower surface of the cap cover 25 is in contact with the mounting step surface 8 a formed in the support recess 8.

  In a state where the cap cover 25 is attached to the cover 6, the upper end portion of the base portion 21 of the lock release lever 20 is disposed in the moving recess 25 c. Therefore, the cap cover 25 can be moved in the front-rear direction while being arranged in the support recess 8 and the movement recess 25c.

  When the cap cover 25 is attached to the cover 6, the upper end of the operation protrusion 22 of the lock release lever 20 protrudes upward from the arrangement hole 25 d.

  When the cap cover 25 is attached to the cover 6, the locking spring 26 is supported between the spring support recess 17 a of the lock member 16 and the spring receiving recess 25 b of the cap cover 25 (see FIG. 5). The lock spring 26 is, for example, a compression coil spring, and the lock member 16 is urged toward the lock position by the lock spring 26.

  A cap 27 made of a metal material is attached to the front end portion of the cover 6 (see FIGS. 3 to 5). The cap 27 includes a circumferential surface portion 27a formed in a substantially U-shape projecting forward, an upper projecting portion 27b projecting inward from the upper edge of the circumferential surface portion 27a, and both left and right side portions of the upper projecting portion 27b.

In the state where the cap 27 is attached to the cover 6, the holding portions 27c and 27c are respectively inserted into the pressed recesses 25a and 25a of the cap cover 25, and the cap cover 25 is pressed from above by the holding portions 27c and 27c (see FIG. 4). Therefore, the cap cover 25 is prevented from being lifted from the cover 6.

  A cap bracket 28 is attached to the supported arm 7 of the operation cap 3 (see FIGS. 3 to 5). The cap bracket 28 is formed by integrally forming a mounted portion 29 and a pressing protrusion 30 protruding rearward from the mounted portion 29, and is fitted to the left and right side surfaces of the mounted portion 29, respectively. Abutting protrusions 29a and 29a are provided. The fitting protrusions 29a and 29a are formed in a hemispherical shape protruding outward.

  The cap bracket 28 is attached to the supported arm 7 by inserting the attachment portion 29 into the attachment recess 15a and fitting the fitting protrusions 29a and 29a into the attachment holes 15b and 15b from the inside.

  In the state where the cap bracket 28 is attached to the supported arm 7, the pressing protrusion 30 is positioned directly above the hammer of the ignition means.

  A frame cover 31 is attached to the front end portion of the upper portion of the case body 4 (see FIGS. 1 to 5). As shown in FIG. 3, the frame cover 31 is formed by integrally forming an upper surface portion 32 and a peripheral surface portion 33 projecting downward from an outer peripheral edge excluding a rear edge of the upper surface portion 32 with a metal material.

  A crater 32a and a lock hole 32b are continuously formed in the upper surface portion 32 in the front-rear direction. Thus, since the crater 32a and the lock hole 32b are continuously formed in the upper surface part 32, the frame cover 31 can be formed easily.

  Air holes 33a, 33a,... Are formed in the peripheral surface portion 33.

  By attaching the frame cover 31 to the case body 4, the nozzle 5 is covered with the frame cover 31, and the crater 32a is positioned directly above the nozzle 5 (see FIG. 5).

  When the lock member 16 is in the lock position, which is the lower moving end, the base portion 17 is inserted into the lock hole 32b of the frame cover 31 from above.

  The case body 4 supports an adjustment knob 34 for adjusting the heating power at a position immediately below the frame cover 31 (see FIGS. 1 and 2).

  In the lighter 1 configured as described above, the ignition operation for the fuel is performed as follows (see FIGS. 5 to 7).

  First, an initial state before the fuel ignition operation is described (see FIG. 5).

  In the initial state, the operation cap 3 is urged by the urging means and held at the closed position, and the crater 32a of the frame cover 31 is closed from above by the closed portion 6a. At this time, the nozzle 5 is positioned at the lower moving end, and the fuel supply path is closed by the valve mechanism of the nozzle unit.

  In the initial state, the lock member 16 is held at the lock position which is the lower moving end by the urging force of the lock spring 26, the base portion 17 is inserted into the lock hole 32 b of the frame cover 31, and the operation cap 3 is connected to the case body 4. It is locked to. Therefore, even if the operation portion 6b of the operation cap 3 is pressed downward in a state where the lock member 16 is in the locked position, the base portion 17 is engaged with the opening edge of the lock hole 32b, and the operation cap 3 is attached to the case body 4. It is not rotated.

  The lock release lever 20 is biased by a biasing spring 24 and is held in a holding position, which is a moving end on the rear side, in an initial state.

  First, the lock | rock with respect to the case body 4 of the operation cap 3 is cancelled | released with respect to the lighter 1 in the above-mentioned initial state (refer FIG. 6). For releasing the lock of the operation cap 3 with respect to the case body 4, for example, the case body 4 is held with one hand, the finger 100 is directed to the upper surface of the operation protrusion 22, and the lock release lever 20 is applied to the urging force of the urging spring 24. Move it to the unlocked position. Since the upper surface of the operation protrusion 22 is formed as a concavo-convex part 22a, it is difficult for the finger 100 to slide with respect to the operation protrusion 22, and good operability can be ensured.

  When the lock release lever 20 is moved from the holding position to the lock release position, the sliding inclined surfaces 23a and 23a of the action portions 23 and 23 of the lock release lever 20 are respectively slid arcs of the action portions 19 and 19 of the lock member 16. The lock member 16 is slid on the surfaces 19a and 19a, and is moved upward from the lock position toward the non-lock position against the urging force of the lock spring 26. When the lock member 16 is moved to the unlocked position, the base portion 17 is pulled upward from the lock hole 32b, and the lock of the operation cap 3 with respect to the case body 4 is released.

  Next, in a state where the lock of the operation cap 3 with respect to the case body 4 is released, the rear end portion of the operation portion 6b of the operation cap 3 is set to the operation direction while the lock release lever 20 is held at the lock release position by the finger 100. It presses downward which is one direction (refer FIG. 7).

  When the rear end of the operation portion 6b of the operation cap 3 is pressed downward, the lock of the operation cap 3 with respect to the case body 4 is released, so that the operation cap 3 is rotated to the open position with respect to the case body 4. Go. Since the operation cap 3 is rotated with respect to the case body 4, the crater 32a of the frame cover 31 is opened.

  When the operation cap 3 is rotated with respect to the case body 4, the nozzle 5 is moved upward, the fuel supply path is opened by the valve mechanism of the nozzle unit, the liquefied fuel is vaporized, and the fuel gas is passed through the fuel pipe. From the nozzle 5. At the same time, when the operation cap 3 is rotated, the hammer of the ignition means disposed inside the case body 4 is pressed downward by the pressing protrusion 30 of the cap bracket 28, and the hammer is lowered to impact the piezoelectric element. Is granted. When an impact is applied to the piezoelectric element, a lighting voltage is generated, and the generated lighting voltage is discharged near the upper end of the nozzle 5 by the high-voltage lead. As the lighting voltage is discharged near the upper end of the nozzle 5, the fuel gas ejected from the nozzle 5 is ignited.

  When the fuel gas is ignited, the ignited fuel gas is burned near the crater 32a of the frame cover 31, and the flame 100 is lit so as to extend upward from the crater 32a.

  In the state where the fuel gas is burning, the frame cover 31 and the cap 27 are particularly heated. However, since the frame cover 31 and the cap 27 are made of a metal material, the frame cover 31 and the cap 27 are excellent. Heat dissipation is ensured.

  When the downward pressing by the finger 100 on the operation portion 6b of the operation cap 3 is released, the operation cap 3 is rotated in the opposite direction to the case body 4 by the biasing means, and the nozzle 5 is moved downward. The fuel supply path is closed by the valve mechanism of the nozzle unit, and the ejection of fuel gas from the nozzle 5 is stopped and extinguished.

  The operation cap 3 returns to the closed position where the crater 32a of the frame cover 31 is closed from above by the biasing force of the biasing means (see FIG. 5). When the operation cap 3 returns from the open position to the closed position, the lock member 16 is moved downward by the urging force of the locking spring 26 to return from the unlocked position to the locked position, and the lock release lever 20 is attached to the urging spring 24. It is moved backward by the force and returns from the unlocked position to the holding position.

  When the operation cap 3 is rotated from the open position to the closed position, the downward pressing by the pressing protrusion 30 of the cap bracket 28 against the hammer of the ignition means is released.

  As described above, in the lighter 1, the lock position that restricts the rotation of the operation cap 3 in the predetermined direction relative to the main body 2 and the rotation of the operation cap 3 in the predetermined direction relative to the main body 2 can be performed. There is provided a lock member 16 that is moved between the lock position and the lock release lever 20 that moves the lock member 16 between the lock position and the lock position.

  Therefore, unless the lock release lever 20 is operated to release the lock, the operation cap 3 cannot be rotated with respect to the case body 4 to perform ignition. Is not rotated and ignition is not performed, and safety can be improved.

  In particular, it is possible to prevent the operation cap 3 from being rotated when a child or a young person has gripped the lighter 1, and safety for the child or the young can be ensured.

  In the lighter 1, the direction in which the operation cap 3 is operated is different from the direction from the holding position of the unlocking lever 20 toward the unlocking position, so that the unlocking lever 20 is held in the holding position. When the operation cap 3 is operated in the state where the lock release lever 20 is operated, it is difficult to operate the lock release lever 20, and it is possible to prevent erroneous operation.

  Furthermore, as described above, the direction in which the operation cap 3 is operated is downward, the direction from the holding position of the lock release lever 20 toward the lock release position is forward, and the direction in which the operation cap 3 is operated and the movement of the lock release lever 20 By making the direction perpendicular to the direction, the lock release lever 20 is not operated when the operation cap 3 is operated in a state where the lock release lever 20 is held at the holding position. It can be surely prevented.

  In the above description, the direction in which the operation cap 3 is operated and the movement direction of the lock release lever 20 are orthogonal to each other. However, the operation direction of the operation cap 3 and the movement direction of the lock release lever 20 are Is not limited to the orthogonal direction, and it suffices if the directions are different from each other.

  In addition, since the lighter 1 is provided with an urging spring 24 that urges the lock release lever 20 toward the holding position, the lock release lever 20 is surely secured when the lock release lever 20 is not operated. Therefore, the safety can be further improved.

  In the above, the example in which the biasing spring 24 for biasing the lock release lever 20 is provided has been described. For example, the lock release using the lock spring 26 for biasing the lock member 16 is performed as follows. The lever 20 can be biased toward the holding position (see FIG. 8).

  The biasing force of the lock spring 26 is applied to the lock member 16 as a downward movement force. At this time, the sliding arc surfaces 19a, 19a of the action portions 19, 19 in the lock member 16 are in contact with the sliding inclined surfaces 23a, 23a of the action portions 23, 23 of the lock release lever 20. At this time, the urging force of the lock spring 26 can be applied to the lock release lever 20 as a backward moving force via the action portions 19 and 19 of the lock member 16.

  Accordingly, when the lock member 16 is moved from the non-lock position to the lock position by the urging force of the lock spring 26 (arrow A), the urging force of the lock spring 26 is moved via the action portions 19 and 19 to the lock release lever. 20 and the unlock lever 20 is moved from the unlock position to the holding position (arrow B).

  Thus, by urging the lock release lever 20 toward the holding position by the lock spring 26, a dedicated spring member for urging the lock release lever 20 is not required, and the number of parts of the lighter 1 is reduced. In addition, the mechanism can be simplified.

  When the urging force of the lock spring 26 is applied to the lock release lever 20, the inclination angle α (see FIG. 8) of the sliding inclined surfaces 19a, 19a of the action portions 19, 19 of the lock release lever 20 is 45 °. It is desirable to enlarge it.

  The shapes and structures of the respective parts shown in the best mode for carrying out the invention described above are merely examples of the embodiments performed in practicing the present invention. The range should not be interpreted in a limited way.
