Abstract

PURPOSE:To enable regulation of a combustion amount through simple consitution and to obtain a given distance of a wick elevating stroke through a short control stroke, by a method wherein an auxiliary lever is pivotally secured to the actuating part side of a main lever, and a wick elevating lever is engaged with the auxiliary lever. CONSTITUTION:With a wick elevating knob 30 depressed, an edge 28c of a control body 28 loweres the control part side of a main lever 17. This causes raising of the actuating part side, and as a result, a shaft hole 24 in the auxiliary lever 22 is raised. A lever 8 is turned through a cam shaft 9 inserted in the shaft hole 24, a wick 4 is raised to a given position. In which case, since the main lever 17 forms a lever acting centering around a pivotally-securing part 18, a distance from the pivotally-securing part 18 to a large hole 19, positioned opposite to the cam shaft 9 for elevating the wick, is set to a size longer than a distance from the pivotally-securing part 18 to a control part, and this provides a long wick elevating stroke even if the depressing stroke of the wick elevating knob 30 is specified. Namely, a given size of a wick elevating stroke can be obtained through a short depressing stroke.

At this point, the ignition heater 62 is designed to come into contact with the lamp wick 4 after the lamp wick 4 has been raised. The ignition heater 52 is energized by a spring 58 so as to return to its original position when the operation body 28 is released from the depression.

In the figure, reference numeral 59 indicates a return spring for returning the operating body 28 to the depressurization-recovery position, and 60il''i is a shock absorber such as a rubber column that absorbs the shock when the main lever is returned to its original position. When you push down the top and bottom knobs 30,
The end edge 28c of the operating body 28 lowers the operating portion side of the main lever 17. As a result, the main lever 1 as shown in FIG.
70, the acting portion side rises, and the shaft hole 24 of the auxiliary lever 22, which is pivotally supported on this acting portion side, rises. The lever 8 is rotated via the camshaft 9 fitted into the shaft hole 24, and the lamp wick 4 is raised at a predetermined position. At this time, the main lever 1 is locked in the position where the lamp wick 4 is raised by the locking pin 42 of the locking fitting 39 fitting into the locking portion 41 on the operating portion side.

Therefore, the lamp wick 4 is held raised. Since the main lever 17 is a lever centered on the pivot part 18, it extends from the pivot part 18 to the large hole 19 facing the camshaft 9 for raising and lowering the wick. If the dimension is made larger than the dimension from the pivot portion 18 to the operating section, a long lead up and down stroke can be obtained even if the pushing and lowering strokes of the lead up and down puller 30 are constant. In this embodiment, the dimension from the pivot portion 18 to the large hole 191 is relatively large, and a predetermined center lowering stroke can be obtained with a short push down stroke.

On the other hand, the operating body 2B pushes down the ignition lever 66 with the main lever 17 and its ignition operating piece 28e. As a result, the lever 64 shown in FIG. 9 rotates, and the ignition heater 6
2 is pushed toward the burner section 2 side, contacts the lamp wick 4, and ignites it. When the operating body 28 releases the pressing force (releases the finger from the top and bottom grip fields of the core), it returns upward by the return spring 58. As a result, the pressing force on the ignition heater 52 is released, and the return spring 58 The auxiliary force returns to the original state and completes the ignition operation. In other words, the ignition heater 52 can ignite the lamp wick 4 at the same time as the lamp wick 4 is raised.

Next, when the fine adjustment knob 38 is pushed down in this state, the movement is transmitted to the auxiliary lever 22 via the operating body 34 and the fine adjustment metal fitting 31, and the auxiliary lever 22 is moved to the main lever 1.
It rotates downward around the pivot point 23 towards the end. As a result, the camshaft 9 fitted into the shaft hole 24 of the auxiliary lever 22 is lowered, and the lamp wick 4 is lowered via the lever 8. Moreover, if the fine adjustment knob 38 is raised from this state, the lamp wick 4 will be raised by the reverse operation. All right, this fine adjustment knob 38
By this operation, the lamp wick 4 can be moved up and down, in other words, the amount of combustion can be adjusted. The vertical adjustment range of the lamp wick 4 is such that combustion can occur normally. A fine adjustment fitting 31 that transmits the movement of the fine adjustment knob 38 to the auxiliary lever 22.
Since a cutout groove 33 for escaping the main lever 17 is formed in the main lever 17, the main lever 17 can be freely adjusted independently of the main lever 17.

Next, if you want to extinguish the fire while it is burning in this condition, press down on the extinguish button, 1p5o. As a result, the acting part 49a of the fire extinguishing lever 490 pushes up the end of the linking metal fitting 45 on the weight side, and the other end of the linking metal fitting 45 rotates downward as shown by the phase image line in FIG. The locking pin 43 is unlocked, that is, the locking fitting 39 is unlocked.

Here, a force is always applied to this lock fitting 39 in the direction of separating from the locking part 41 of the main lever 17 (in the direction of arrow A in FIG. 8) due to the spring force of the tension spring 21 provided on the main lever 17. When the lock by the linking metal fitting 46 is released, the locking pin 42 of the locking metal fitting 39 is separated from the locking portion 41 of the main lever 17. As a result, the main lever 17 is rotated so that the acting portion side thereof is lowered by the biasing force of the tension spring 21, and the shaft hole 24 of the auxiliary lever 22, which is pivoted to the acting portion side of the main lever 17, is also lowered. Then, the camshaft 9 fitted into the shaft hole 24 is also lowered, and the lamp wick 4 is lowered via the lever 8 to extinguish the fire. The upper edge 17a of the operating section side of the main lever 17 still engages the edge 28c of the operating body 28 to raise it to its original position. At this time, since the fine adjustment metal fitting 31 that straddles the main lever 17 is provided with a cutout groove 33 for escape of the main lever, even if the main lever 17 returns to the upward position, the main lever 17 will come into contact with it for fine adjustment. Metal fittings 31
That is, the auxiliary lever 22 does not rise together with the main lever 17. Therefore, when using the main lever 17 by pressing it down again, the lamp wick 4 is moved by the auxiliary lever 2.
2, the wick height is set to the height adjusted by 2, and it becomes necessary to adjust the wick height every time the lamp is reused.

Next, we will explain how to extinguish fires in the event of an earthquake or the like. When an earthquake or the like occurs, this is sensed and the weight 47 tilts in the left-right or front-back direction, and the action plate 48a attached to the lower end of the shaft 48 pushes up the north end of the weight.

Thereafter, the lamp wick 4 descends to extinguish the fire in the same manner as the fire extinguishing operation by the fire extinguishing knob 5o described above.

Effects of the Invention As is clear from the description of the embodiments, the present invention uses the main lever for lifting the wick as a lever, so by selecting the lever ratio, a predetermined amount of wick can be raised with a short operation. A vertical stroke can be obtained, making it easy to operate the lead up and down. In addition, since an auxiliary lever that moves the lamp wick position up and down is pivotally supported on this main lever, the amount of combustion can be adjusted using this auxiliary lever.Moreover, in the present invention, this adjustment of the amount of combustion is performed on the operating part of the main lever. It can be done with a simple configuration of pivoting the auxiliary lever, and its effects are impressive.
