Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wick up/down device for a wick type oil combustor.

Conventional Technology In general, this type of oil burner burns and extinguishes fire by moving the lamp wick up and down. The vertical movement of the vertical arm 73 and the vertical lever 76 of the vertical mechanism 75, which is connected to the vertical arm 73 through the vertical shaft 74, is performed. Recently, as shown in FIG. 8, a rack 77 attached to the wick up/down lever 76 and a pinion 79 built into the operation base 78 have been used to gradually drive the wick up/down lever 76 within the combustion range to adjust the firepower. You can see what has been made possible. In addition, 80 in the figure
81 is a slide shaft that rotatably holds the pinion 79 and slides back and forth with respect to the operation base 78; 81 is a slide shaft 80;
A fine adjustment knob 82 drives the pinion 79 via the center vertical lever 7 after adjusting the positional relationship between the pinion 79 and the rack 77 to the normal dimensions in the vertical and longitudinal directions.
A fixing screw 83 integrated with 6 is a rack shaft for supporting the rack 77 coaxially with the core vertical lever 76.

Problems to be Solved by the Invention However, in the oil combustor having the above configuration, in order to convert the rotational movement of the fine adjustment knob 82 into a linear movement by the slide shaft 80 and further rotate the pinion 79, the direction of movement must be changed. If a part becomes stiff and requires more operating force than necessary,
There was a problem with parts wearing out.

The present invention was made in view of these points, and aims to make the transmission of motion to the pinion smooth and free of twisting, and to reduce the operating force.

Means for Solving the Problems In order to achieve the above object, the present invention provides a lamp wick that is vertically movable;
A wick up and down mechanism having a wick up and down lever that moves the wick up and down, a vertically movable rack connected to the wick up and down lever, a support that holds this rack so that it can move up and down, and a support for the rack. The rack is provided with a pinion that can be moved toward and away from the rack and rotated freely, and a pinion that moves the rack in small steps, and an operation button that operates the pinion. The dimension from the center of rotation to the operating section is larger than the dimension from the center of rotation to the meshing portion of the binion with the rack.

Effect of the present invention With the above structure, the combustion amount can be adjusted by either the core up/down lever or the fine adjustment operation button, and the motion transmission to the pinion is smooth without twisting, and the operating force is reduced. It can be made lighter and is very easy to use.

EXAMPLES The following examples will be explained with reference to FIGS. 1 to 6. First, in Figures 1 to 3, 1 is a core guide tube, 2 is a core outer tube arranged with a gap around the outer periphery of the core guide tube 1, and 3 is a core guide tube 1 and a core outer tube 2. A lamp wick that can be moved up and down between 4
is a combustion tube that burns the fuel vaporized from the lamp wick 3.

Next, a manually operated wick up and down mechanism 5 that moves the lamp wick 3 up and down.
I will explain about it. First, reference numeral 6 denotes an on-wick lever for vertically moving the lamp wick 3, and one end thereof is connected to the lamp wick 3 through a suitable connecting means as described in the conventional example. This core up/down lever 6 is rotatably supported on the core up/down board 7 by a pin 8 along the way, and the Zyu 9 is connected to the core up/down lever 6.
In addition, an ignition lever is pivotally supported on the upper and lower core boards by a pin 8, and an ignition device (not shown) is connected to one end 9a of the ignition lever.
is activated to ignite the lamp wick 3, and after the ignition operation, it automatically returns to its original position.

Numeral 10 is a core upper and lower plate which is pivoted to the core upper and lower substrates by pins 8 together with the core upper and lower lever 6, and is linked to the core upper and lower lever 6 by appropriate means. A spring 11 biases the wick upper and lower plates 10 toward the upper position (wick lowered position), and is hooked between the ends of the wick upper and lower plates 10 and the wick upper and lower substrates 7. Reference numeral 12 designates a locking plate that holds the wick upper and lower plates 1° in a lower position (wick raised position), and is rotatably supported by a pin 12a.

This lock plate 12 has a long hole 14 through which a pin 13 implanted in the upper and lower core plates 1o is inserted, and a locking portion 14a is formed at the end of the long hole 14 to lock the pin 13. It looks like this. In other words, push down the core up/down lever 6 (
wick up/down direction), the wick upper/lower plate 10, which is linked with the wick up/down lever 6 by appropriate means, rotates downward (the pin 13 of the wick upper/lower plate 10 descends along the elongated hole 14, and the elongated hole 14 ), when the pin 13 reaches the end of the locking part 1
4a, the core upper and lower plates 1o become longer at that position despite the biasing force of the spring 11. 15 is a temporary spring attached to the lock plate 12, 16 is this temporary spring 15
It is a weight for vibration extinguishing that is connected to the core via a chain 17, and is erected on a pedestal 18 provided on the core upper and lower substrates 7. This weight 16 slides when an earthquake occurs and rotates the temporary spring 15, that is, the lock plate 12 via the chain 17. This allows long hole 1
The pin 13 is disengaged from the locking portion 14a of 4, and the core upper and lower plates 10 are rotated upward by the biasing force of the spring 11. At this time, since the wick upper and lower plates 10 are linked with the wick up and down lever 6, the wick up and down lever 6 also rotates upward, and the wick 3 is lowered to extinguish the fire. At this time, pin 13 returned to the upper position.
presses the leaf spring 15 and pulls the chain 17, returning the fallen weight 16 to its original state. Reference numeral 19 denotes an emergency and fire extinguishing button, which is formed integrally with the lock plate 12 and is adapted to rotate the lock plate 12 in the same way as the weight 16.

Next, the fine adjustment mechanism 20, which is a feature of the present invention, will be explained using FIGS. 1, 4, 5, and 6. First, reference numeral 21 denotes a vertically movable rack, one end of which is linked to the core vertical lever 6 by suitable means. Reference numeral 22 denotes a support body 2, which is composed of a base body #A and a lid body 22B as shown in FIG. They fit together and are integrated. Reference numeral 26 designates a rotatable upper operation button, which has an upper operation part 26a at the upper part and a centering bearing 27 approximately at the center.
3, and is biased in a direction away from the rack 21 by an upper operation button spring 29 provided between the base body 22A of the support body.

30 is a rotatable upper operation button, and the upper operation part 30 is located at the bottom.
A also has a center lowering bearing 31 approximately in the center, and the bearing provided at the upper part is pivoted to the operating shaft 23 at a portion 32, and the upper operating shaft 23 provided between the base body 22 of the support body The button spring 33 is biased in a direction away from the rack 21. Reference numeral 34 denotes a centering pinion, which is pivotally supported by the centering bearing 27 of the upper operation button 26 and a snake-nion shaft 35, and is biased toward the rack 21 by a pinion pushing spring 36 provided between it and the upper operation button 26. be. 37 is a center lowering pinion, which is a center lowering bearing 31 of the upper operation button 30.
It is pivotally supported by a hepinion shaft 35, and the upper operation button 3
The pinion push spring 36 provided between the rack 2 and the
It is biased in one direction.

Then, each of the operation buttons 26, 30 and the pinion 34.
37 is the rotation center of each operation button 26.30, that is,
The dimension from the operating shaft 23 to each of the operating parts 26a, 30a is set larger than the dimension 1 from the operating shaft 24 to the engagement position of each pinion 34, 37 with the rack 21.

Note that 40 is an operation base body on which the integrated fine adjustment mechanism 20 is attached and fixed, and is integrally attached to the core upper and lower substrates 7.

Next, the operation of the oil combustor wick up-and-down device configured as described above will be explained below.

First, when the wick up/down lever 6 is pushed down from the pre-use state shown in FIG. 2, the wick 3 shown in FIG. The lamp wick 3 is lit. The ignition lever 9 then returns to its original state.

At this time, the fine 1m joint mechanism 20 linked to the core up and down lever 6
The rack 21 is similarly pushed down and the centering pinion 34
, comes to face the core lowering pinion 37.

As described above, the wicking and ignition operations are completed.

Once combustion starts, the amount of combustion can be adjusted by moving the wick up and down lever 6 up and down, but the adjustment of the amount of combustion by operating the fine adjustment mechanism 20 will be explained with reference to FIGS. 4 to 6. . First, when the lamp wick 3 is set to the combustion position, the rack 21 is moved by the wick raising pinion 34 as shown in FIG.
and the core lowering pinion 37. To reduce the combustion amount, operate the upper operation part 30a of the upper operation button 30 in the direction of arrow Sa as shown in FIG.
Center lowering pinion 37 pivotally supported by the upper operation button 30
engages with the rack 21, which is normally in an uncoupled state, and rotates in the direction of the arrow, thereby pushing the rack 21 up in the direction of the arrow E. As a result, the wick up/down lever 6 linked to the rack 21 is also pushed up in the direction of arrow E, and the wick 3 is therefore lowered. At this time, if you press the upper operation button 3o once, the core lowering pinion 37
are set in a dimensional relationship such that at least one tooth of the rack 21 is fed.

When the core lowering pinion 37 finishes feeding one or more teeth of the rack 21, the upper operation button 30 is moved by the upper operation button spring 3 provided between the base body 2 of the support body and the upper operation button 30.
3 returns to the original state shown in FIG. 4, and the core lowering pinion 37 and the rack 21 are disengaged from each other. Also,
The center lowering pinion 37 returns to its original state because the pinion pushing spring 36 is always biased in the direction of arrow G. By the above operation, the wick 3 is lowered little by little,
The amount of combustion can be reduced little by little.

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 part 26a of the main operation button 26 is operated in the direction of arrow Sb, the centering pinion 34 engages with the rack 21, which is normally in an uncoupled state, and moves in the direction of arrow H. The rack 21 is rotated to push down the rack 21 in the direction of arrow J. As a result, the wick up/down lever 6 linked to the rack 21 is also pushed down in the direction of arrow J, so that the wick 3 is raised. At this time, when the main operation button 26 is pressed once in the same way as when lowering the centering, the centering pinion 34 is moved to the rack 2.
The dimensional relationship is set such that at least one tooth of No. 1 is advanced. When the centering pinion 34 has finished feeding one or more teeth of the rack 21, the main operation button 26 is moved by the main operation button spring 29 provided between the base body 22 of the 6° holding body and the main operation button 26. The force returns to the original state shown in FIG. 4, and the centering pinion 34 and the rack 21 are disengaged from each other. Further, the centering pinion 34 returns to its original state because the pinion pushing spring 36 is always biased in the direction of arrow G.

As described above, in this combustor, the combustion amount can be adjusted by the wick up/down mechanism 5 and the combustion amount by the fine adjustment mechanism 20.
Rack 21 and centering pinion 34 and centering pinion 3
7 is normally in an uncoupled state, so the core up-and-down mechanism 5 allows
The fire can be extinguished by freely lowering the wick 3.

In addition, in this core up-and-down device, the rotational movement of each operation button 26.30 is directly transmitted to each pinion 34.37 to cause it to rotate, so the operation of each operation button 26.36 is Without wasting power, each pinion 34.3
7, and no twisting occurs at that time.Furthermore, the dimensions from the center of rotation of each operation button 26.30 to the operation section are as large as each pinion 34.3.
Since the dimension is set larger than the dimension from the center of rotation of 7 to the engagement portion with rack 21, the operating force for operating buttons 26 and 30 can be light due to this principle.

In the above embodiment, the main operation button and the main operation button are described as separate parts, but the same effect can be obtained even if these are integrated.

More than the effects of the invention, as is clear from the description of the embodiments, the lead up/down device of the present invention uses a fine adjustment mechanism in addition to the lead up/down mechanism to allow the lead up/down in small steps.・After raising and lowering the wick to extinguish a fire or making large-scale adjustments to the combustion amount, the fine adjustment mechanism can be used to make small adjustments to the combustion amount.The series of operations of the fine adjustment mechanism can be made smoother, and the operation force is lighter. This makes it extremely reliable and easy to use.
