DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the petroleum combustor having the above-described structure, the stove body has been downsized recently, and accordingly, the distance 1 from the pivot point 54 of the lever 53 becomes short, and the lever 53 has a small amount. There is a problem that the wick 51 moves largely by operation, and when the user tries to adjust the combustion amount a little, it is difficult to make fine adjustment, and in terms of usability it is just a step away.

The present invention has been made in view of the above points, and makes it possible to easily adjust the combustion amount and to easily set the most important point in assembly for that purpose. This is the purpose.

Means for Solving the Problems In order to achieve the above object, the present invention provides a manually operated core up-and-down mechanism for vertically moving a wick, and a core up-and-down mechanism when not normally linked to the core up-and-down mechanism. A fine vertical adjustment mechanism for engaging and driving this in small increments is provided, and a rack for driving in small increments is attached movably up, down, front and back, and the position of the fine adjustment pinion is set on the rack. The structure is provided with a gauge projection that comes into contact with the pinion so that it can be easily carried out.

Action The present invention can adjust the combustion amount by either the core up / down mechanism or the core up / down fine adjustment mechanism according to the above configuration, and the positional relationship between the fine adjustment rack and the pinion can be set easily and accurately. Like

EXAMPLE An example will be described below with reference to FIGS. 1 to 7.

First, in FIGS. 3 and 4, 1 is a core guide cylinder, 2 is a core outer cylinder which is arranged on the outer periphery of the core guide cylinder 1 with a gap, and 3 is between the core guide cylinder 1 and the core outer cylinder 2. Wick provided vertically on the 4
(See FIG. 7) is a combustion cylinder for burning the fuel vaporized from the wick 3.

Next, a manually operated core up / down mechanism 5 for vertically moving the wick 3
The same will be described with reference to FIGS. 3 and 4. First, reference numeral 6 denotes a core upper and lower body (hereinafter referred to as a core vertical lever) for moving the wick 3 up and down, and one end of the wick is linked to the wick 3 through an appropriate linking means. The core up-down lever 6 is rotatably supported by a pin 8 (see FIG. 1) on a core up-down board 7 in the middle thereof. Reference numeral 9 denotes an ignition lever pivotally supported on the core upper and lower base plate 7 by a pin 8 together with the core upper and lower lever 6, and one end portion 9a of the ignition lever operates an ignition device (not shown) to ignite the wick 3. After operation, it automatically returns to its original position. 10
Like the ignition lever 9, is a core upper / lower plate pivotally supported on the core upper / lower base plate 7 by a pin 8 together with the core upper / lower lever 6, and is linked to the core upper / lower lever 6 by an appropriate means. Reference numeral 11 denotes a spring for urging the core upper and lower plates 10 toward the upper position (the wick lowering position), which is hooked between the end of the core upper and lower plates 10 and the core upper and lower substrates 7. 12 is the core upper and lower plates 1
With a lock plate that holds 0 at the lower position (the wick rising position),
It is pivotally supported by a pin 12a. The lock plate 12 is formed with a long hole 14 into which the pin 13 planted in the upper and lower core plates 10 is inserted, and a locking portion 14a is formed at the terminal end of the long hole 14 to lock the pin 13. It is like this. That is, when the core up / down lever 6 is pushed down (in the direction of raising the wick), the core up / down plate 10, which is linked to the core up / down lever 6 by appropriate means, rotates downward (the pin 13 of the core up / down plate 10 is moved to the elongated hole 14). Down along that slot 1
4), the pin 13 fits into the locking portion 14a and locks the core upper and lower plates 10 at that position in spite of the biasing force of the spring 11. 15 is a lock plate 12
A leaf spring 16 attached to the above is a weight for vibration extinguishing linked to the leaf spring 15 through a chain 17, and is erected on a pedestal 18 provided on the upper and lower substrate 7 of the core. The weight 16 swings in the event of an earthquake to rotate the leaf spring 15, that is, the lock plate 12, via the chain 17. As a result, the locking portion 1 of the long hole 14
The pin 13 is disengaged from the 4a, and the urging force of the spring 11 causes the upper and lower core plates 10 to rotate upward. At this time, the lead upper and lower plates 10 are linked to the lead up and down levers 6, so that the lead up and down levers 6 also rotate upward, and the wick 3 is lowered to extinguish the fire. At this time, the pin 13 that has returned to the upper position presses the leaf spring 15 to pull the chain 17, and the weight 16 that has fallen is returned to the original inverted state. 19 is an emergency fire extinguisher button, and a fire extinguisher button support shaft 19
The lock plate 12 is pivotally supported by a and rotates the lock plate 12 in the same manner as the weight 16.

Next, the vertical fine adjustment mechanism 20 will be described with reference to FIGS. 1, 2, and 5A and 5B.

In this state, the adjuster lever 21a is temporarily fastened to the auxiliary lever 21 with a screw at an arbitrary position, and the other end of the auxiliary lever 21 is screwed to the core up-down lever 6. That is, the auxiliary lever 21 is adapted to perform the same rotational movement in association with the rotational movement of the core up-down lever 6, and the rack 2 mounted on the adjuster lever 21a.
3 also makes the same rotational movement. Reference numeral 25 denotes a base body, which is integrally attached to the core upper and lower substrates 7. The base body 25 has a core raising fulcrum shaft 26a and a core lowering fulcrum shaft 26b. Reference numeral 27 denotes a center-raising operation body, the bearing portion 27a of which is rotatably fitted to a center-raising fulcrum shaft 26a provided on the base body 25. Reference numeral 28 denotes a core lowering operation body, and its bearing portion 28a is rotatably fitted in the core lowering fulcrum shaft 26b like the center raising operation body 27. Reference numeral 29 is a center-raising slide body, 30 is a center-lowering slide body, and the center-raising slide body 29 is slidably fitted in a bearing 31a provided on the base body 25 to provide a center-lowering slide body. Three
0 is slidably fitted in the bearing 31b. Reference numeral 32 denotes a lead-up pinion provided at a position facing the rack 23, and is pivotally supported by the spindle 33 on the lead-up slide body 29. A core lowering pinion 34 is provided at a position facing the rack 23 similarly to the core raising pinion 32, and is pivotally supported by the support shaft 35 on the core lowering slide body 30. 36 is a slide return spring for raising the core, which is a base body 25.
Is attached to a spring support shaft 37a provided on the
3, the other end is engaged with the spring receiver 38a of the base body 25. Reference numeral 38 is a slide return spring for lowering the core, which is attached to a spring support shaft 37b, one end of which is engaged with the support shaft 35 and the other end of which is engaged with a spring receiver 38b. Reference numeral 39 denotes a lead-up pinion return spring mounted on the support shaft 33, one end of which is engaged with the lead-up slide body 29 and the other end of which is engaged with the lead-up pinion 32. Reference numeral 40 denotes a core lowering pinion return spring mounted on the support shaft 35, one end of which is engaged with the core lowering slide body 30 and the other end of which is engaged with the core lowering pinion 34. The above-described center-raising / center-lowering slide bodies 29 and 30, the support shaft 3
A clutch mechanism 24 is constituted by 3, 35, center raising, center lowering pinions 32, 34, center raising / lowering slide return springs 36, 38, center raising / center lowering pinion returning springs 39, 40, and rack 23. ..

Next, the position setting (adjuster method) of the rack 23 and the center-up and center-down pinions 32 and 34 will be described.

First, from the state before use in FIGS. 1 and 3 to the core up-down lever 6
When pushed down, the adjuster lever 21a, which is set to the combustion position and is integrally attached to the core up / down lever 6 and temporarily fastened to the auxiliary lever 21, also performs the same rotational movement as the core up / down lever 6, and the adjuster lever Two
As shown in FIGS. 5A and 5B, the rack 23 attached to the la 1 is in a positional relationship facing the center raising / lowering pinions 32, 34 of the center vertical fine adjustment mechanism 20. In this state, the gauge projection 23a provided at the end of the rack 23 on the core rising side is placed on the tip of the core lifting pinion 32 which is biased in the non-coupling direction by the core lifting pinion return spring 39, and brought into contact with the front and rear direction. After adjusting with the adjuster lever 21a, if the auxiliary lever 21 is fully tightened, the vertical and forward / backward position setting is completed at the same time. That is, the relationship between the pitch (P ₁ ) of the center-raising / lowering pinion and the pitch (P ₂ ) between the rack gauge projections 23a and the rack roots is determined so that the first start-up of the centering pinion 34 is always performed on the same root of the rack 23. By setting to engage with each other, the positional relationship in the vertical direction is always constant. Also in the front-back direction, by setting a minimum step (H ₁ ) that maintains a normal non-coupling state from the tooth tips of the rack 23 and setting a gauge protrusion, the rack 23 and the center-raising / center-lowering pinions 32, 34 are connected. The gap (H ₂ = H ₁ ) can be stabilized.

Next, the operation of the core lifting device for an oil combustor configured as described above will be described below.

First, from the state before use in FIGS. 1 and 3 to the core up-down lever 6
4 is pushed down, the wick 3 rises to the combustion position as shown in FIG. 4 and an ignition device (not shown) is operated via the ignition lever 9 to ignite the wick 3. Then, the ignition lever 9 returns to the original state. At this time, the auxiliary lever 21 and the adjuster lever 21a integrally attached to the core up / down lever 6 also perform the same rotational movement as the core up / down lever 6, and the rack 23 attached to the adjuster lever 21a moves the core up / down fine adjustment mechanism 20. It comes to face the core raising and lowering pinions 32 and 34. At this time, the pin up / down lever 6 is further pushed down by the play of the pin 13 with respect to the locking portion 14a of the lock plate 12, and even if the rack gauge projection 23a pushes down the core raising pinion 32, the pinion 32 is rotated in the rotating direction (see FIG. 6). , H direction indicated by C, there is no problem.

The core raising / ignition operation is completed as described above. When combustion starts, the amount of combustion can be adjusted by moving the wick up-and-down lever 6 up and down. Regarding the adjustment of the amount of combustion by operating the wick up-and-down fine adjustment mechanism 20, see FIGS. 6A to 6C. It demonstrates using. First, as shown in FIG. 6B, when the wick 3 is set to the combustion position, the rack 23 is set to the position facing the core raising pinion 32 and the core lowering pinion 34 as described above. When reducing the amount of combustion, see Fig. 6A.
When the core lowering operating body 28 provided on the base body 25 is operated in the direction of the arrow Sa as shown in FIG. 5, the contact piece 28b pushes the protruding piece 30a of the core lowering slide body 30, and the core lowering slide body 30 is Fa inside the bearing 31b provided in the body 25
The core lowering pinion 34, which slides as shown in FIG.
3 to rotate in the direction of arrow D as it is,
Will be pushed up in the direction of arrow E. As a result, the adjuster lever 21 to which the rack 23 is attached
The core up / down lever 6 is also pushed up in the direction of the arrow E via the a and the auxiliary lever 21, so that the wick 3 is lowered. At this time, when the core lowering operation body 28 is pushed once, the core lowering pinion 34 has such a dimensional relationship that only one tooth of the rack 23 is fed. Core down pinion 34
When the rack feeds one tooth of the rack 23, the center-lowering slide body 34 returns to the original state shown in FIG. 6B by the urging force of the center-lowering slide return spring 38 which is engaged with the support shaft 35. At the same time, the core lowering operation body 28 also returns to the original state, and the engagement between the core lowering pinion 34 and the rack 23 is released. Further, the core lowering pinion 34 returns to the original state because the core lowering pinion return spring 40 is always biased in the direction of the arrow G. That is, by the action of the clutch mechanism 24, the linkage with the core up / down lever 6 of the core up / down mechanism 5 is disconnected, and the original state is restored. By the above operation, the wick 3 can be lowered in small steps, and the combustion amount can be gradually reduced.

Next, when increasing the combustion amount, the operation body 27 for raising the core
You can operate. That is, as shown in FIG. 6C, when the center-raising operation body 27 rotatably fitted to the center-lowering fulcrum shaft 26a is operated in the direction of arrow Sb, the contact piece 27b moves the center-raising slide body 29. When the projecting piece 29a is pressed, the centering slide body 29 slides in the bearing 31a provided in the base body 25 as shown by an arrow Fb, and the centering pinion 32 pivotally supported by the centering slide body 29 is normally Engages with the rack 23 in the non-coupling state and rotates in the direction of arrow H as it is,
The rack 23 is pushed down in the direction of arrow J. That is, the core up / down lever 6 is pushed down in the direction of arrow J, so that the wick 3 is raised. At this time, when the core raising operation body 27 is pushed once as in the case of the core lowering, the center raising pinion 32
Has a dimensional relationship such that only one tooth of the rack 23 is fed. When the center-raising pinion 32 finishes feeding one tooth of the rack 23, the center-raising slide body 29 is moved by the urging force of the center-raising slide return spring 36, which is engaged with the support shaft 33, as shown in FIG. 6B. When returning to the state, the centering operation body 27 also returns to the original state, and the engagement between the centering pinion 32 and the rack 23 is disengaged. Further, the core-raising pinion 32 returns to its original state because the core-lowering pinion return spring 39 is constantly urged in the direction of arrow K.

As described above, the rack 23 and the core raising / lowering pinion 3 which are important for adjusting the combustion amount by operating the core vertical fine adjustment mechanism 20.
The position setting (adjuster) of the upper, lower, front and rear with respect to 2, 34 can be easily completed simultaneously by the gauge protrusion 23a of the rack 23.

The initial start of the core lowering pinion 34 starts from the same tooth bottom of the rack 23, which means that the number of feed teeth up to the position of the lowermost tooth 23b of the rack 23 does not vary depending on the number of teeth of the molding rack 23. Also, depending on the pitch (P ₁ ) of both pinions 32 and 34, the centering pinion 32
Will be decided in the same way. That is, the rotation range of the core up / down lever 6 and the fine adjustment movable range of the combustion core height can be set, the lower limit of the core height can be managed, and the core height position can be displayed by rotating the core up / down lever 6, for example. Up·
The lower limit position display can be stably determined.

Also in the front-back direction, the gap between the two pinions 32, 34 is stably determined by the molding step (H ₁ ) of the rack 23, and the minimum gap (H ₂ = H ₁ ) that maintains a normal non-coupling state can be secured. At the same time, conversely, the gap (H ₂ ) becomes large, so that the feed of both pinions 32, 34 becomes insufficient, and the engagement of the pinions 32, 34 in the next operation with the rack 23 becomes loose, or the tooth surface of the rack 23 is reduced. It is possible to set in advance the phenomenon that slippage will occur and it will not be possible to make reliable fine adjustment of the core up and down.

FIG. 7 shows an example of an oil combustor using the core lifting device of the present embodiment. 41 is a door attached to the base body 25, 42 is an ignition knob attached to the tip of the ignition lever 9, and 43 is an ignition knob. Is a core up / down knob attached to the tip of the core up / down lever 6. As the operation procedure of the user, first, open the door 41 and push up the ignition knob 42 and the core upper and lower knobs 43 located inside thereof to ignite the wick 3, and when combustion starts, the core upper and lower knobs 43 or the core lowering knob Operating body 2
The amount of combustion is adjusted by 8 and the core raising operation body 27.

EFFECTS OF THE INVENTION As is clear from the above description of the embodiments, the core up / down device of the present invention uses the core up / down mechanism in addition to the core up / down fine adjustment mechanism so that the core can be moved up and down in small steps. point·
