BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a core lifting device for a wick type oil combustor.

2. Description of the Related Art Generally, in this type of oil combustor, the wick is moved up and down to burn and extinguish, and the vertical movement of the wick moves the pin 72 of the wick 71 to the upper and lower arms of the wick as shown in FIG. 73 and the core up-down lever 76 of the core up-down mechanism 75 linked to this core up-down arm 73 via the up-down shaft 74, are moved up and down. Recently, as shown in FIG.
Rack 77 installed on the rack, the rack 77 installed on the operation base 78 side, and the rack installed on the operation base 78 side
There is a fine adjustment mechanism that drives the core up-down lever 76 in small steps by a pinion 79 that can be moved in and out of contact with and rotatable with respect to 77 so that the heat power can be easily adjusted within the combustion range. In the figure, 80 is a slide shaft that holds the pinion 79 rotatably and slides back and forth in the guide groove of the operation base 78,
82 is a fine adjustment knob that drives the pinion 79 via the slide shaft 80, 83 is a fixing screw that integrates the rack 77 with the core up / down lever 76, and 84 is a rack for supporting the rack 77 coaxially with the core up / down lever 76. It is an axis.

SUMMARY OF THE INVENTION However, the oil combustor having the above-described configuration has a fine adjustment knob 82.
And the pinion 79, a slide shaft 80 for transmitting the pushing force of the fine adjustment knob 82 to the pinion 79 is required, and there is a problem that the configuration is complicated and the size becomes large.

Therefore, the applicant has considered a fine adjustment mechanism in which the slide shaft is eliminated by directly pushing the operation button to directly drive the pinion. However, this mechanism has a problem in that when the fine adjustment button is pushed in the horizontal direction, the opposite side projects more than the front surface of the main body, and the appearance is significantly impaired.

The present invention has been made in view of the above circumstances, and aims to prevent the opposite side from protruding from the front surface of the main body even when the operation button is pushed horizontally while simplifying the configuration.

Means for Solving the Problems The present invention provides a vertically movable wick to achieve the above object,
A core up / down mechanism having a core up / down lever for vertically moving the wick, a vertically movable rack connected to the core up / down lever, a support for holding the rack vertically movable, and a rack for driving the rack. A pinion for raising and lowering the core, which is rotatably attached to and detached from the pinion, and an operation button for operating both the pinions, and the operation button has its substantially central portion pivoted on the support. The pinion is freely pivoted, and the pinions are provided on both end sides with the pivot part as a boundary so that the pinion can be used fully by pushing operation of both end parts. It is divided into two parts and made independent. In addition, the operation button is exposed on the outer surface side of the operation base, and the operation button is projected from the front surface of the main body by abutting the operation base or the support body at appropriate positions on both ends of the operation button. It has a structure provided with a protruding piece for preventing.

Operation The present invention can adjust the combustion amount by either the core up-and-down mechanism or the fine adjustment mechanism by the above configuration, and further, the slide shaft can be eliminated and the configuration can be simplified. Further, even if the operation button is pushed in the horizontal direction, the opposite side can be prevented from protruding from the front surface of the main body.

EXAMPLE An example will be described below with reference to FIGS. 1 to 7. First, in FIGS. 1 to 3, 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 a core guide cylinder 1 and a core outer cylinder 2. A wick provided vertically between the two
Is a combustion cylinder for burning the fuel vaporized from the wick 3.

Next, a core up-and-down mechanism 5 for operating the means for vertically moving the wick 3
Will be described. First, reference numeral 6 is an on-core lever for moving the wick 3 up and down, and one end of the wick 3 is linked to the wick 3 through an appropriate linking means. The core up / down lever 6 is rotatably supported by a pin 8 on a core up / down base plate 7 in the middle thereof. Reference numeral 9 denotes an ignition lever pivotally supported on the core upper / lower board 7 by a pin 8 together with the core upper / lower lever 6 at one end thereof.
An ignition device (not shown) is operated by 9a to ignite the wick 3, and after the ignition operation, it automatically returns to its original position. 10 is this ignition lever 9
Similarly to the core up / down lever 6, a core up / down plate pivotally supported on the core up / down base 7 by a pin 8 together with the core up / down lever 6, and is linked to the core up / down lever 6 by an appropriate means. Reference numeral 11 is a spring for urging the upper and lower plates 10 above (the wick lowering position).
It is hooked between the ends of the core upper and lower plates 10 and the core upper and lower substrates 7. Reference numeral 12 is a lock plate that holds the core upper and lower plates 10 at a lower position (a wick rising position), and is pivotally supported by a pin 12a. This lock plate 12 is a pin that is planted in the upper and lower core plates 10.
A long hole 14 through which the 13 is inserted is formed, and a locking portion 14a is formed at the terminal end of the long hole 14 to lock the pin 13. 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 an appropriate means, rotates downward (the pin 13 of the core up / down plate 10 is moved to the long hole 14). Down along the end of the elongated hole 14), the pin 13 is fitted into the locking portion 14a and the spring 1
Despite the urging force of 1, the core upper and lower plates 10 are locked at that position. Reference numeral 15 is a leaf spring attached to the lock plate 12, and 16 is a weight for vibration extinction linked to the leaf spring 15 via a chain 17, which is erected on a pedestal 18 provided on the core upper and lower substrates 7. . The weight 16 slides 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 pin 13 is disengaged from the locking portion 14a of the elongated hole 14, 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 descends 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 restore the weight 16 that has fallen to its original state. An emergency fire extinguisher button 19 is formed integrally with the lock plate 12, and is adapted to rotate the lock plate 12 similarly to the weight 16.

Next, the fine adjustment mechanism 20, which is a feature of the present invention, will be described with reference to FIGS. 1, 4, 5, and 6. First, 21 is a vertically movable rack, one end of which is linked to the core up / down lever 6 by an appropriate means. 22 is a support body, a base body 22A and a lid body 22B

A lower operation button spring 33 provided between the two is urged in a direction away from the rack 21. 34 is a center-raising pinion, which is pivotally supported by a pinion shaft 35 on a center-raising bearing 27 of the upper operation button 26, and a rack by a pinion pushing spring 36 provided between the upper-operation button 26 and the upper operation button 26.
It is biased in the 21 direction. Reference numeral 37 is a core lowering pinion, which is pivotally supported by the pinion shaft 35 to the core lowering bearing 31 of the lower operation button 30, and is urged toward the rack 221 by the pinion pushing spring 36 provided between the lower operation button 30 and the center. There is. That is, the fine adjustment mechanism 20 includes the rack 21, the support 22, and the upper operation button 26.
And core lifting pinion 34, pinion shaft 35, and pinion push spring
Upper operation button unit 38 consisting of 36 and lower operation button 30
A core lowering pinion 37, a lower operation button unit 39 including a pinion shaft 35 and a pinion pressing spring 36, an upper operation button spring 29, and a lower operation button spring 33 are integrally attached.

Reference numeral 40 denotes an operation base for mounting and fixing the integrated fine adjustment mechanism 20, which is integrally mounted on the upper and lower core substrates 7.

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

First, when the lead up / down lever 6 is pushed down from the state before use in FIG. 2, the wick 3 is raised to the combustion position as shown in FIG. 3 and the ignition device (not shown) is operated via the ignition lever 9. , The wick 3 is ignited. Then, the ignition lever 9 returns to the original state. At this time, the rack 21 of the fine adjustment mechanism 20 linked to the lead up / down lever 6 is also pushed down to face the lead-up pinion 34 and the lead-down pinion 37. The core raising / ignition operation is completed as described above.

When the combustion starts, the amount of combustion can be adjusted by the vertical movement of the core up / down lever 6, and the adjustment of the amount of combustion by operating the fine adjustment mechanism 20 will be described with reference to FIGS. 4 to 6. . First, when the wick 3 is set to the combustion position, the rack 21 is set to a position facing the core raising pinion 34 and the core lowering pinion 37 as shown in FIG. When the lower operation button 30 is operated in the direction of the arrow Sa as shown in FIG. 6 to reduce the combustion amount, the core lowering pinion 27 pivotally supported by the lower operation button 30 is normally in the non-coupling rack 21.
, And the rack 21 is rotated in the direction of arrow D as it is, and the rack 21 is pushed down in the direction of arrow E. As a result, the lead up / down lever 6 linked with the rack 21 is also pushed up in the direction of the arrow E, so that the wick 3 is lowered. At this time, when the lower operation button 30 is pressed once, the core lowering pinion 37 is set to have a dimensional relationship such that at least one tooth of the rack 21 is fed. The core down pinion 37 is a rack
When one or more teeth 21 have been fed, the lower operation button 30 is returned to the original state shown in FIG. 4 by the urging force of the lower operation button spring 33 provided between the base body 22 of the support and the lower operation button 30. Then, the engagement between the core lowering pinion 37 and the rack 21 is released. Further, the core lowering pinion 37 returns to the original state because the pinion pushing spring 36 is constantly biased in the direction of the arrow G. 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 upper operation button 26 may be operated. That is, as shown in FIG. 5, when the upper operation button 26 is operated in the direction of the arrow Sb, the centering pinion 34
Normally engages with the rack 21 in the non-coupling state, rotates in the direction of arrow H as it is, and pushes down the rack 21 in the direction of arrow J. As a result, the lead up-and-down lever 6 linked with the rack 21 is also pushed down in the direction of arrow J, so that the wick 3 is raised. At this time, as in the case of lowering the center, when the upper operation button 26 is pressed once, the center-raising pinion 34 has a dimensional relationship such that at least one tooth of the rack 21 is fed. When the centering pinion 34 finishes feeding one or more teeth of the rack 21, the upper operation button 26 is moved to the fourth position by the urging force of the upper operation button spring 29 provided between the base body 22 of the support and the upper operation button 26. Returning to the original state shown in the figure, the engagement between the centering pinion 34 and the rack 21 is disengaged.
Further, the center-raising pinion 34 returns to its original state because the pinion pushing spring 36 is constantly biased in the direction of arrow C.

In this core up / down device, the up / down operation buttons 26, 30 are formed separately and the ends of the up / down operation buttons are used for the support 22. Therefore, as shown in FIGS. Manual operation button
The operation buttons on the opposite side do not project outward even if you press 26 or 30. Moreover, in this embodiment, the operation base 40 in which the projecting pieces 26a and 30a are provided on the operation buttons 26 and 30 is provided.
Since it is located inside, even when one operation button 26 is pressed and the other operation button 30 tries to rotate outward due to the frictional force of the shaft support portion, the protrusion 30a is located on the inner surface of the operation base 40. Since they come into contact with each other, the operation buttons 26 and 30 can be more reliably prevented from protruding without further outward rotation.

Note that FIG. 8 shows an example of an oil combustor using the core lifting device of the present embodiment, 41 is a door attached to the operation base body 40, and 42 is a tip of the ignition lever 9. An ignition knob 43 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 down the ignition knob 42 and the core upper and lower knobs 43 inside the door 41 to ignite the wick 3, and when combustion starts, the core upper and lower knobs 43 or the upper operation button. The amount of combustion is adjusted by the 26 and the lower operation button 30.

EFFECTS OF THE INVENTION As is apparent from the description of the embodiments above, the core up / down device of the present invention uses the fine adjustment mechanism in addition to the core up / down mechanism so that the core can be moved up and down in small steps.・ After adjusting the top and bottom of the core for extinguishing the fire and making a large amount of combustion adjustment, you can finely adjust the amount of combustion with the fine adjustment mechanism, and the other side does not protrude from the front of the main body when the operation button is pushed horizontally. The number of parts can be reduced and simplification can be achieved.
