The specific embodiment

With reference to Fig. 1 and Fig. 2, symbol 1 is fire power regulator of the present invention.Symbol 2 is handle members that firepower is regulated use, utilizes pin 23 and support 22 to link, and this support 22 is retained and can freely swings centered by swinging axle 21.In addition, compression is provided with aftermentioned spring 24 between support 22 and handle member 2.

In said structure, handle member 2 can swing centered by swinging axle 21 on left and right directions, and can swing centered by pin 23 on above-below direction.In addition, spring 24 is so that the mode to the front end application of force of handle member 2 works towards the below.

In this fire power regulator 1, be built-in with by present known plugs (not shown) such as Japanese patent laid-open 9-159053 communiques.This plug is truncated cone shape, is formed with the opening that becomes the gas passage at side face.In addition, also be formed with opening taking on the perisporium of plug, when the opening of perisporium was consistent with the opening of plug, gas was supplied to the gas burner in downstream via this consistent part.In addition, make the plug rotation, if the area change of consistent part, the gas flow that is supplied to gas burner increases and makes firepower become large, and on the contrary, if the area of consistent part reduces, the gas flow that is supplied to gas burner reduces and firepower is diminished.In addition, the area of consistent part is further reduced, when the area of consistent part is zero (full-shut position), gas can not be supplied to gas burner fully, and gas burner is flame-out.

This plug is accommodated in the below of stop pin 4.In addition, the connecting pin 31 of rotation is connected with plug centered by this stop pin 4.Therefore, when making this connecting pin 31 rotation centered by stop pin 4, be accommodated in the plug of below with identical angle rotation.Yet these stop pin 4 lockings when stop pin 4 is positioned at illustrated latched position, even if want to make connecting pin 31 rotations, can not make connecting pin 31 rotations so that plug is in full-shut position and plug is not rotated.

Stop pin 4 is by towards the top application of force, and when overcoming this active force and depress stop pin 4, the position of stop pin 4 becomes the latch-release position and the state that unlocks.If form this state, can make connecting pin 31 rotations and make the plug rotation, but at the state that makes the rotating torques continuous action in connecting pin 31, be under the state of plug continuous rotation, even if be provided with the power on direction depressed removed for stop pin 4, also can not make stop pin 4 be back to the mechanism of top.Because this mechanism is known according to above-mentioned Japanese patent laid-open 9-159053 communique etc., therefore omit detailed explanation, if but make the plug rotation under the state of depressing stop pin 4, plug can rotate to the ignition location that is set in the position of crossing fully open position, open microswitch at this ignition location, make igniter (not shown) work, so that gas burner is begun spark discharge.Under this state, plug is identical with full-gear, therefore, from gas burner ejection gas, and utilizes spark that gas burner is lighted a fire.

When the rotating torques removed connecting pin 31, stop pin 4 is back to the top because of active force, if but be back under this state in the firepower adjustable range, can not make connecting pin 31 cross fully open position and rotate to ignition location.In addition, even if stop pin 4 is back to the top, to plug be back to full close position and make gas burner flame-out before, the lock function of stop pin 4 can not worked yet, consequently, plug can rotate freely in the firepower adjustable range that is sandwiched between full-shut position and fully open position, according to the firepower of this anglec of rotation adjustments of gas burner.

Be back to Fig. 1, be formed with slotted hole 25 at the middle part of handle member 2, handle member 2 is being installed under the state of support 22, connecting pin 31 is inserted through slotted hole 25.

Symbol 11 is partition, in the situation that be applied with the liquid material such as water from the place ahead, is used for this liquid material is blocked and can not be had influence on the part that is built-in with plug.In addition, meanwhile, also can limit, excessively not depress handle member 2 in the situation that depress as described later the front end of handle member 2.Particularly, when handle member 2 is depressed, is formed at the protuberance of giving prominence to towards the below 26 of handle member 2 and the upper limb butt of partition 11, thereby limits so that handle member 2 can not be further depressed.In addition, depressing handle member 2 so that under the state of the upper limb butt of itself and partition 11, the frictional force when swinging for reduction forms protuberance 26.In addition, the safety jaw 27 of restriction use is formed at handle member 2, when in the situation that the front end edge left and right directions of handle member 2, namely regulate the direction momentary action along firepower larger power is arranged, make safety jaw 27 and

safety wall

32a, 32b butt make this power not act on plug.

With reference to Fig. 3 and Fig. 4, the effect of the fire power regulator 1 of said structure is described.Because the slotted hole 25 of handle member 2 engages with connecting pin 31, therefore, when handle member 2 swings from illustrated full close position towards fully open position, connecting pin 31 rotations and make the plug rotation.Yet at full close position, the locking of stop pin 4 is worked, and therefore, if do not remove this lock-out state, can not make handle member 2 begin to swing from full close position.

As mentioned above, need to depress stop pin 4 for the state of unlocking.Therefore, when depressing the front end of handle member 2, the front end butt of the lower surface of handle member 2 and stop pin 4 is to depress stop pin 4.Yet therefore stop pin 4, in order to depress the front end of handle member 2, need be overcome the front end of towards the top, the active force of stop pin 4 application of forces being depressed handle member 2 by towards the top application of force.Herein, the active force of above-mentioned spring 24 works towards the direction of the front end that reduces handle member 2, therefore, utilizes the active force of spring 24 can reduce the actual required power of front end of depressing handle member 2.In addition, even if not with state that handle member 2 contacts under, the active force that also can utilize spring 24 towards the below application of force, therefore, can prevent rocking of handle member 2 to handle member 2, and the sensation can improve the front end of holding the handle member and operate the time.

As mentioned above, when handle member 2 is swung from full close position towards fully open position, at first, depress the front end of handle member 2, make stop pin 4 be positioned at the latch-release position.Under this state, the protuberance 26 of handle member 2 and the upper limb lower curtate 11a butt of partition 11.When the handle member is swung towards right, although protuberance 26 move along upper limb lower curtate 11a, can the rub lower surface of handle member 2 of the front end of stop pin 4.When handle member 2 was further swung, protuberance 26 was climbed up the high 11b of section of upper limb.

Under the state that handle member 2 swings continuously, even if removed the power of depressing to stop pin 4, the state that also can keep stop pin 4 to descend continuously.Therefore, when protuberance 26 was climbed up the high 11b of section of upper limb, handle member 2 was away from the front end of stop pin 4, can the not rub lower surface of handle member 2 of stop pin 4.

When handle member 2 was further swung towards right, handle member 2 was crossed fully open position and is rocked to ignition location.When the igniting that confirms gas burner, make hand away from handle member 2 herein.Like this, push away on the stop pin 4 that handle member 2 is replied towards the top, and be back to fully open position.Under this state, gas burner is lighted a fire, therefore, and if handle member 2 is moved in the firepower adjustable range, firepower that can the adjustments of gas burner.In addition, when making handle member 2 be back to full close position at last, the locking work of stop pin 4 if again do not depress handle member 2, can not make handle member 2 swing towards right.

In the above-described embodiment, this is two-layer because the upper limb with partition 11 is made as upper limb lower curtate 11a and the high 11b of section of upper limb, therefore, in the swing of handle member 2 midway, the front end of stop pin 4 does not contact with the lower surface of handle member 2, but also can form recess at the lower surface of handle member 2, to avoid from swinging to stop at this recess from stop pin 4 front end.

With reference to Fig. 5, in said structure, direction F and the direction M that connecting pin 31 wishs move of revolving force that puts on connecting pin 31 because of the swing of handle member 2 is inconsistent under nearly all state.This is because of the oscillation center 21 of handle member 2 and inconsistent the causing of pivot (setting position of stop pin 4) of connecting pin 31, but this is the anglec of rotation cause larger than the pendulum angle of handle member 2 of wanting to make connecting pin 31.Yet,, can't be effective as revolving force and be passed to connecting pin 31 power on the swaying direction of handle member 2 when inconsistent as the direction F of above-mentioned revolving force and moving direction M, consequently, the operation sense that produces handle member 2 becomes heavy such unfavorable condition.

Therefore, in these cases, as shown in Figure 6, also can make by the swing of handle member 2 gear wheel 5 rotation, and make linkedly the plug rotation with pinion 51 with these gear wheel 5 engagements.In this structure, can will be made as efficiently the revolving force of plug to the operating physical force of handle member 2, the operation sense of handle member 2 is lightened.In addition, by changing gear ratio, can freely change the pendulum angle of handle member 2 and the ratio of the anglec of rotation of plug.

In addition, in said structure, make the width of front end of handle member 2 thinner than the width of other parts, in the situation that unwanted larger masterpiece is used for front end, fore-end is out of shape with absorbability, but as shown in Figure 6, also breach 2a can be set, come absorbability initiatively partly to locate distortion at breach 2a.

In addition, the present invention is not limited to above-mentioned embodiment, also can carry out various changes in the scope that does not break away from purport of the present invention.
