Abstract

PURPOSE:To reduce the number of component parts and an assembling time and reduce operating force to eliminate a lack of pushing stroke of a safety valve by a method wherein a rotary plate is provided with an L-shaped bent part and a projection and they are fitted in the cutout groove and the fitting hole of a receiving plate, one end surface of a connector is made flat and pressing of a closing spring member is always applied to an operating shaft. CONSTITUTION:Under a gas cut-off condition, an L-shaped bent part 5b of a rotary plate 5 is fitted into a cutout groove 7a of a receiving plate 7 and a gas passage 20 is not opened only by rotating operation of an operating shaft 1. When a pushing stroke more than a height of the bent part 5b is received, a lock is released and at the same time a safety valve 10 is opened. When a rotational operation is carried out, the closing element 2 rotates through a connector 3 to open a pilot gas passage 16 and a main gas passage 17. Upon ignition, when a hand is removed from the operating shaft 1, a pilot valve 12 is closed, only the main gas passage 17 is opened. Since a closing spring 4 applies pushing pressure against the operating shaft 1 through the connector 3, a clearance is secured between the operating shaft 1 and the pilot shaft 11. When a fire power is changed from strong state to weak state, the projection 5a of the rotary plate 5 is fitted into the fitting hole of the receiving plate 7 to give a feeling of saving and a sound of saving to a user.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gas cock device for supplying gas to a gas burner such as a domestic gas stapler.

Conventional technology Conventionally, gas cock devices that housed a closure were opened by pushing and turning the operating shaft when the gas stop was in the gas stop position for safety reasons, and the closure was opened in the low heat position for convenience when doing things such as simmering. Many are easily adjustable.

An example of the conventional gas cock device mentioned above will be described below with reference to the drawings.

FIG. 3 shows a cross section of a conventional gas cock device. (Al is in a gas stop state. In Fig. 3, 1
2 is an operating shaft, 2 is a closure for opening and closing the gas passage 20, and 3 is a connector, which links the rotation of the operating shaft 1 with the closure 2.

4 is a closing spring that prevents the closing member 2 from floating up, and 5 is a rotating plate that rotates together with the operating shaft 1. Reference numeral 6 denotes an operating spring that always pushes the operating shaft 1 forward (towards a knob (not shown) via the rotating plate 5 and the stopper A9 when the gas is stopped). 7 is a receiving plate that kites the operating shaft 1; 8 is a mounting plate fixed to the gas cock body 19 with screws; 10 is a safety valve; 11 is a device that transmits the axial movement of the operating shaft 1 to the safety valve 10 and opens and closes the pilot valve 12. This is the pilot axis. 1a is a return spring, and 14 is a retaining ring B. In FIG. 3B, reference numeral 8a denotes a hole in the mounting plate 8 into which the stopper 3a is fitted.

The operation of the gas cock device configured as described above will be explained below.

When the operating shaft 1 is first pressed from the gas stop state as shown in Fig. 3(,), the stopper 38 and the stopper hole 8 appear as shown in Fig. 3(b).
The pilot valve 12.a is disengaged and the pilot valve 12.a is attached to the pilot shaft 11. opens, the safety valve 10 is pressed, and the safety valve 10 becomes open. In this state, operate 1
When 1111 is rotated counterclockwise, the closure 2 is rotated via the connector 3, the gas passage 20 is opened, and gas flows in the direction of the arrow and is supplied to the gas burner.

Also, after that, when you release your hand from the operating shaft 1, the pilot spring 1
8, the high lot valve 12 is closed and only the main gas passage 17 is opened.

Problems to be Solved by the Invention However, in the above configuration, when the gas is burned as shown in FIG. It no longer touches the operating shaft 1. Therefore, the clearance 15 between the operating shaft 1 and the pilot shaft 11 is too small, and the operating shaft 1 is loose in the axial direction.
There is a tendency for the pilot valve 12 to open and a pilot flame to be emitted by pressing the button. Ta. For this reason, there were problems in that the number of parts increased, the pushing load was heavy, and the operability was poor.

Furthermore, as shown in FIG. 3(-), since the height of the stopper 31 is low, the lock is released by a slight push stroke during ignition, and the operating shaft 1 tends to continue to rotate. As a result, there was a problem in that the safety valve 12 could not be pushed completely and the valve would not open.

The present invention is intended to solve these problems, and reduces the number of parts and assembly time of the gas cock device, as well as
The present invention provides a gas cock device that reduces operating force and eliminates insufficient push stroke of a safety valve.

Means for Solving the Problems In order to solve the above problems, the gas cock device of the present invention has the following features:
A gas passage is opened in the gas cock body by a rotating operation following a pushing operation of the operating shaft from the gas stop position, and a closing element that rotates against a closing spring, and a closing element that connects this closing element and the operating shaft and that rotates. The gas hook includes a movable connector, an operating spring interposed between a receiving plate that holds the operating shaft and a mounting plate fixed to the gas hook body, and a rotating plate that interlocks with the operating shaft against the operating spring. One end surface of the connector forms a plane that is in constant contact with the operating shaft, the rotary plate is provided with an L-shaped bent part and a protrusion is provided on the plane part, and the receiving plate is provided with a gas stop position. and a notch groove into which the bent portion fits, and a fitting hole into which the protrusion fits at the firepower setting position.

Operation According to the above-described structure of the present invention, when the gas is stopped, the L-shaped bent portion of the rotary plate and the notch groove of the receiving plate are fitted, so that the lock cannot be released only by rotating the operating shaft. Further, when the operating shaft is rotated after the push stroke reaches the height of the L-shaped bent portion of the rotary plate and the lock is released, the safety valve enters an open standby state.

Next, when the operator releases the operating shaft after igniting the gas burner, the operating shaft is constantly pressed by the closing spring via the connector, so that a predetermined clearance between the operating shaft and the pilot shaft is maintained.

EXAMPLE Hereinafter, a gas hook device according to an example of the present invention will be described with reference to the drawings. Note that the same parts as in the above conventional example are given the same reference numerals, detailed explanations are omitted, and different parts will be mainly explained.

FIG. 1 shows the gas stop state of the gas cock device in the embodiment of the present invention. In this (-) state, the L-shaped bent portion 5b formed on the rotating plate 5 is Notch #
7a, so it is in a locked state. Therefore, the gas passage 20 cannot be opened only by turning the operating shaft 1.

Next, when the operating shaft 1 receives a push stroke greater than the height of the L-shaped bent portion 5b of the locked rotating plate 5, the lock is released and at the same time the safety valve 10 is opened. A push stroke is received by the pilot shaft 11 to open the valve. When this push operation is followed by a rotation operation as shown in FIG. 1(b), the closure 2 rotates via the connector 3, the pilot gas passage 16 and the main gas passage 17 are opened, and the gas burner (not shown) is connected to the gas burner (not shown). Gas is supplied.

Next, Fig. 1 (,) shows a state in which the hand is released from the operating shaft 1 after ignition, the pilot valve 12 is closed, and the main gas passage 1
Only 7 are open. Even in this state, the closing spring 4 applies pressure to the operating shaft 1 via the connector 3, so the operating shaft 1
A predetermined gap 15 between the pilot shaft 11 and the pilot shaft 11 is reliably secured. In addition, since there is no play in the operating shaft 1, the operating shaft 1 easily contacts the pilot shaft 11 while adjusting the firepower with the closure 2 by rotating the operating shaft 1, and the pilot gas is released. There is no problem that it becomes.

Also, when the firepower is switched from strong to weak, the protrusion 5a of the rotating plate 5
is fitted into the fitting hole 7b of the receiving plate 7, giving the user a sense of moderation and a moderation sound, making it possible to easily adjust the firepower.

Effects of the Invention As described above, the present invention has a configuration in which the rotating plate is provided with an L-shaped bent portion and a protruding portion, which fit into the notch groove and fitting hole of the receiving plate, and one end surface of the connector is made flat and always Since it applies the pressure of the closing spring to the operating shaft, it has the following effects.

(1) Since the required stroke for opening the safety valve is equal to the push stroke for releasing the lock at the time of ignition, the safety valve can be reliably opened.

(2) Since the return spring and retaining ring B for the operating shaft, which were conventionally required, are no longer required, the pushing force during operation is reduced, the usability is improved, and the number of parts and assembly time can be reduced.

Furthermore, since the overall length of the operating shaft is shortened, the gas cock device itself can be made more compact and can be easily accommodated in the instrument body.

(3) When cooking at low heat for boiling, etc., the open position gives a sense of moderation and a moderation sound, allowing the cook to easily determine the open position, improving usability.
