A pendulum shaft 76 is attached to the lower end of the seismic pendulum 71 passing through the clutch lever 72 and the base 70, and a disk 77 is formed at the lower end of the pendulum shaft 76. A portion of the peripheral edge of the disc 77 comes into contact with the clutch lever 72 in response to the tilting of the seismic pendulum 71, so that the clutch lever 72 rotates clockwise against the spring 74. A forced fire extinguishing lever 78 is provided on the front surface of the board 13, and this forced fire extinguishing lever 78 is rotatably supported via a pin 73 and elastically biased counterclockwise by a spring 80. . A bent piece 81 is formed on the forced extinguishing lever 78, and this bent piece 81 protrudes through the opening 82 of the base plate 13 to the rear side thereof, and is disposed so as to face one end of the clutch lever 72. Note that 83 is a control knob for the forced fire extinguishing lever 78.

Next, the operation will be explained. When the ignition slider 47 and the adjustment slider 46 are pulled down along the sliding groove 45 from the state shown in FIG. 3, the ignition lever 18 and the operating lever 19 are rotated clockwise in conjunction with this. At this time, since the operating lever 19 presses the bent piece 35 of the locking lever 21, the locking lever 21 also rotates clockwise together with the operating lever 19 against the spring 37, and is further locked. Since the restraint piece 34 of the lever 21 presses the restriction piece 28 of the release lever 20, the release lever 20 also rotates integrally. And as shown in Figure 4,
As the locking lever 21 rotates, the clutch plate 38 at the other end comes into contact with the locking pin 75 of the clutch lever 72, and the locking portion 39 engages with the locking pin 75.
This prevents the locking lever 21 from rotating counterclockwise. The operating lever 19 is integrally connected to the operating shaft 6 via the support tube 15, and therefore, as the operating lever 19 rotates, the operating shaft 6
rotates clockwise, and the lamp wick 4 is rotated clockwise through the interlocking fitting 7.
is pushed up above the fire pan 3, and its upper end rises to the upper limit position of the combustible range. Further, when the ignition lever 18 is rotated, an ignition mechanism (not shown) operates in conjunction with this, and the lamp wick 4 is ignited.Afterwards, when the ignition slider 47 is released from being pulled down, the ignition lever 18 is moved by the biasing force of the spring 22. Rotate counterclockwise and return to the original position. When the wick 4 is ignited, the liquid fuel in the oil tank 1 is sucked up into the wick 4 and vaporized one after another, and combustion starts and continues with this vaporized gas.

When combustion is started in this manner, strong combustion continues because the wick 4 is held at the upper limit position of the combustible range. If the combustion power is to be adjusted from this state to medium combustion or weak combustion, the adjustment slider 46 is moved up and down and the operating lever 19 is rotated.

On the other hand, when extinguishing a fire, adjust the adjustment slider 4.
6 by applying a certain amount of force above the firepower adjustment range. According to this, operation lever 1
9 contacts and presses the regulating piece 28 of the release lever 20, and due to this pressing force, the locking pin 42 that engages with the hook 31 moves along the elongated hole 41 against the locking spring 43. As a result, the engagement between the locking pin 42 and the hook 31 is released, and as a result of this release, the operating lever 19 is rotated counterclockwise by the biasing force of the return spring 40, and the locking piece 34 of the locking lever 21 is rotated. It stops when it comes into contact with it. By such an operation, the lamp wick 4 is pulled down below the combustible area, that is, below the fire pan 3, thereby achieving extinguishment.

In this way, when extinguishing a fire, the adjustment slider 46 is pushed upward to release the engagement between the hook 31 and the locking pin 42; If the lock is too strong, a large operating force will be required to release the lock, reducing operability; if the lock is too weak, the lock will easily be released carelessly by a slight vibration, etc., resulting in an accident. The fire will be extinguished. The strength of the engagement force between the hook 31 and the locking pin 42 is greatly influenced by the bending angle of the hook; that is, the larger the bending angle, the stronger and more stable the engagement state. However, on the other hand, it becomes difficult to release, and the operability deteriorates as described above.

[Purpose of invention]

This invention was developed with this focus in mind, and its purpose is to maintain the engagement between the locking pin and the hook in a strong and stable state, while also making it easy to release the engagement. It is an object of the present invention to provide a wick operating device for a wick type combustor which allows smooth operation.

[Summary of the idea]

In other words, this invention has an operating lever, a locking lever, and a release lever arranged coaxially, and the operating lever is linked to a wick that can be raised and lowered, and when the operating lever is operated, the release lever is provided on the locking lever. The wick is rotated integrally against the ignition spring and is locked to the locking lever via the locking mechanism to raise and hold the wick in the combustible area.In this state, the wick is released by rotating the operating lever. The above-mentioned locking mechanism has a long hole formed in the locking lever, a locking pin loosely engaged with the long hole, and the locking pin being held by a locking spring. The release lever is elastically biased toward one end of the elongated hole, and a hook-shaped hook with a large bending angle is formed on the release lever, and this hook is engaged with the locking pin to form a release piece on the operation lever. By rotating the operating lever, this release piece is brought into contact with the locking pin and moved to the other end of the elongated hole against the locking spring, and this movement prevents the locking pin from engaging with the hook. Upon release, the operating lever is rotated together with the release lever by the biasing force of the return spring, and the wick is lowered to the extinguishing position below the combustible range.

[Example of idea]

An embodiment of this invention will be described below with reference to FIG. In this embodiment, parts corresponding to the conventional configuration are given the same reference numerals, and only different parts will be described.

The tip of the hook 80 of the release lever 20 is bent at a large angle, approximately at a right angle, and a release piece 81 is integrally formed and protrudes from the lower edge of the intermediate portion of the operating lever 19 so as to be adjacent to the hook 80. There is.
The distal end of the release piece 81 extends downward from the hook 80 and is bent at a gentler angle smaller than the bending angle of the hook 80.

In FIG. 1a, the hook 80 engages with the locking pin 42, and the wick is held in the combustible range, with the solid line indicating weak combustion and the broken line indicating strong combustion. In the state of weak combustion, the release piece 81 is in contact with the locking pin 42, and a slight play is left between the upper edge of the operating lever 19 and the regulation piece 28 of the release lever 20. Then, within the range of weak combustion and strong combustion, operate lever 1.
By turning 9, the combustion state can be adjusted almost steplessly, and the range of rotation is indicated by, for example, a scale.

In this state, when the operating lever 19 is slightly rotated counterclockwise via the operating pin 48 to take it out of the combustion adjustment range, the release piece 81 is displaced upwardly before the hook 80 due to the play. This displacement causes the locking pin 42 to engage the locking spring 4.
3, the elongated hole 41 moves from one end side to the other end side, and the engagement between the locking pin 42 and the hook 80 is released, and with this release, the operating lever 19 is moved by the biasing force of the return spring 40. The locking piece 34 of the locking lever 21 rotates counterclockwise together with the release lever 20.
It comes into contact with and stops. With this action, the wick is pulled down below the combustible area, and the fire is extinguished.

The hook 80 is formed in the shape of a hook that bends greatly, and therefore, when it engages with the locking pin 42, it engages reliably, and therefore the engagement is inadvertently released due to vibration or the like. This ensures that accidental extinguishing of fires is prevented. When it is time to release the engagement, the release piece 81 moves the locking pin 42 against the locking spring 40 and releases it from the hook 80, so this is always achieved smoothly and accurately. be done.

[Effect of idea]

As explained above, according to this invention, it is possible to firmly, stably and accurately engage the locking pin and the hook, and therefore it is possible to reliably prevent the occurrence of accidental extinguishing, and when extinguishing The effect is that the engagement can be easily and smoothly released to improve operability.
