Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure for opening and closing a gas outlet closure in a gas outlet.

[Background Art] In the case of a conventional gas outlet, a plug to which a gas socket can be detachably connected and a gas socket for supplying gas to the plug are placed adjacent to each other, and the plug is placed in a plane parallel to the board on which the gas outlet is attached. The gas socket is provided with an operating section that opens and closes the closure by rotating the operating section, and when the operating section is pressed in the closed state, the gas socket is detached from the plug via the interlocking body.
However, in such conventional systems, opening and closing the gas outlet and disconnecting the gas socket must be performed by operating the same operating part in different ways, making handling of the gas outlet complicated and making it difficult to use. Moreover, the structure is extremely complicated and the cost is high because the operating part opens and closes the closing member by rotating it, and the gas socket is released by pressing the operating part. It was hot.

[Purpose of the invention] The present invention has been made in view of the above points, and the purpose of the invention is to provide an operating lever for opening and closing the gas socket closure and a release push button for removing the gas socket. To provide a gas outlet which is easy to handle and has a simple structure because they are separate, and which is easy to open and close because the operation lever swings to open and close the closure.

By using the button 28 to open and close the gas socket 3, and by using the release push button 28 to disconnect the gas socket 1, the closing mechanism 4 and the gas socket 1 can be opened and closed separately, making handling easier. It has become easier to open and close, and the structure has been simplified, and the closing member 4 can be opened and closed by swinging the operating lever 5, making it easier to open and close.
The gas socket 1 can be removed by pressing the release push button 28 only when the operating lever 5 is in the closed state, making it safer.

The present invention will be explained in detail below with reference to Examples.

The gas outlet A is housed inside a case 10 as shown in FIG. 1, and is attached to a mounting board 11 such as a wall plate or a floor plate. A mounting frame 13 is attached to the rectangular opening 12 of the mounting board 11, and the case 10 is attached to the mounting frame 13.
can be installed. As shown in FIGS. 1 and 2, a decorative frame 14 is attached to the front side of the attachment frame 13, and a lid 15 that can be opened and closed is attached to the decorative frame 14. A decorative cover 16 is mounted inside the decorative frame 14 to cover the excess portion of the gas outlet A. As shown in FIG. 1, the gas socket 3 of the gas outlet A is provided with a plug 2 projecting upward, and the gas socket 1 can be detachably connected to the plug 2. The gas inlet 17 and the plug 2 communicate with each other via the closure 4,
By rotating the closure 4, the supply of gas to the plug 2 is opened and closed. In other words, it can be opened and closed by rotating the closing element 4 within a range of 90 degrees. The closing shaft 9 of the closing member 4 protrudes from the gas cock 3, and connects one end of the interlocking lever 6 to the sixth
As shown in the figure, it is connected to a closing shaft 9. One end of the operating lever 5 is rotatably attached to a rotary shaft 8 provided below the closing shaft 9, and a connecting shaft 7 integrally protruding from the other end of the interlocking lever 6 is inserted into the connecting hole of the operating lever 5. 38, the interlocking lever 6 and the operating lever 5 are rotatably connected by the connecting shaft 7. In other words, the length between the closing shaft 9 and the connecting shaft 7 is made shorter than the length between the rotating shaft 8 and the connecting shaft 7. The other end of the operating lever 5 is provided with an operating knob 18 located within the opening of the decorative frame 14. As shown in FIG. 7, an interlocking section 19 is integrally extended from the lower part of the operation knob 18, and the upper surface of the interlocking section 19 is an arcuate surface. The upper surface of the interlocking part 19 is pressed by an arc-shaped presser spring piece 20.
0 is fixed to a base 21 with screws 22 on both sides. This presser spring piece 20 has a pair of locking holes 23.
A locking protrusion 24 that removably locks into the locking hole 23 is protruded from the upper surface of the interlocking part 19. The locking protrusion 24 and the locking hole 23 allow the operation knob 18 to be The range of rotation is regulated. A notch 25 is provided at the end of this interlocking portion 18 . Further, an arch-shaped mounting bracket 26 is provided upright on the base 21, and a release push button 28 is arranged in a sliding hole 27 in the upper part of the mounting bracket 26 so as to be slidable up and down. 29 is made to protrude upward. The lower part of the release push button 28 is supported by a guide rod 30 so as to be slidable up and down. The release push button 28 has a sliding hole 2.
7 is provided, and a spring 39 is interposed between the upper piece of the mounting fitting 26 and the crocodile portion 31 to urge the release push button 28 downward. As shown in FIG. 7, a protrusion 32 that can be engaged with the notch 25 is provided on the surface of the release push button 28 on the interlocking part 19 side. In other words, when the release push button 28 is lowered with the operating lever 5 in the closed state, the notch 25 and the protrusion 32 are engaged as shown in FIG. 8(b), and when the operating lever 5 is in the open state, as shown in FIG. 8(c). Protrusion 3 as shown in
2 hits the upper surface of the interlocking part 19 to prevent it from descending. In this way, the safety mechanism B is constituted by the interlocking part 19, the notch 25, the protrusion 32, etc. The interlocking body 33 is pivoted at its center by a pivot shaft 34 and is mounted to allow free see-saw movement. One end of the interlocking body 33 is a contact portion 36 that comes into contact with the operation ring 35 of the gas socket 1. An engaging portion 37 at the other end of the crocodile portion 33 is engaged with the lower surface of the crocodile portion 31.

Next, the operation of the gas outlet A configured as described above will be explained. 3a, b, and c show the state in which the gas socket 1 is connected to the plug 2, and the closure 4 is in the closed state. In this state, the operation ring 35 protrudes downward, and the operation ring 35 pushes the contact part 36 of the interlocking body 33 downward, and the engagement part 37 pushes the alligator part 31 upward, and the push button part 29 of the release push button 28 stands out. Further, since the release push button 28 is raised, the notch 25 and the protrusion 32 are not engaged with each other and are separated, as shown in FIG. 8a, so that the operating lever 5 can be swung in the opening direction. When the operating lever 5 is swung in the opening direction as shown in FIG. 4, the interlocking lever 6 is swung together with the operating lever 5, causing the closing member 4 to rotate and opening the closing member 4. At this time, since the length between the rotating shaft 8 and the connecting shaft 7 is longer than the length between the closing shaft 9 and the connecting shaft 7, the swing angle α of the operating lever 5 is determined as shown in FIGS. 6a and 6b. The swing angle β of the interlocking lever 6 becomes larger, and the closing member 4 is rotated by an angle larger than the swing angle of the operating lever 5. In this embodiment, when the operating lever 5 swings approximately 45 degrees, the interlocking lever 6
is designed to swing approximately 90 degrees and rotate the closing member 4 by 90 degrees. Therefore, even if the swing angle α of the operating lever 5 is small, the closing member 4 can be opened and closed by rotating the closing member 4 by 90 degrees.
There is no need to make the width of gas outlet A wider than necessary. In this open state, the push button part 2 of the release push button 28
Even if 9 is pressed, the protrusion 32 of the safety mechanism B hits the upper surface of the interlocking part 19 and does not descend as shown in FIG.
It never comes off. When the operating lever 5 is swung in the closing direction from this open state, FIGS.
It is in the closed state as shown in c. In this state, the protrusion 32 of the safety mechanism B and the notch 25 correspond to each other as shown in FIG.
When is pressed, the release push button 28 is lowered, and the notch 25 and the protrusion 32 are engaged with each other as shown in FIG. 8b. When the release push button 28 is lowered, the engaging part 37 of the interlocking body 33 is pushed by the alligator part 31 as shown in FIGS. Press upward to disconnect gas socket 1 from plug 2 and remove gas socket 1. With gas socket 1 removed, operate lever 5.
Even if an attempt is made to swing the operating lever 5 in the opening direction, the protrusion 32 of the safety mechanism B and the notch 25 are engaged with each other, as shown in FIG. I can't. When the gas socket 1 is connected to the plug 2 from this state, the operation ring 35 projects downward, the abutment part 36 is pushed, and the abutment part 37 pushes the disconnection push button 28 upwards, as shown in FIG.
The state will be as shown in b and c. Further, when the gas outlet A configured as described above is attached to the mounting board 11 of a wall plate, the A direction in FIG. 1 is directed toward the ceiling, and the B direction is directed toward the floor. That is, the gas outlet A is installed so that the release push button 28, the operating lever 5, the plug 2, and the gas inlet 17 of the gas outlet A are lined up from the ceiling side to the floor side. Then, when the gas socket 1 is connected to the plug 2, the gas hose connected to the gas socket 1 will hang down to the floor, and the gas hose will not be located in front of the operating lever 5 or the release push button 28, and the operating lever will not be obstructed by the gas hose. 5 and the release push button 28 can be operated.

[Effects of the invention] As described above, the present invention includes a plug to which a gas socket can be detachably connected, a gas socket that opens and closes the supply of gas to the plug, and a gas socket that is arranged adjacent to the gas socket and swings. The gas socket is equipped with an operating lever that rotates the closing member of the gas socket, and a detaching push button that is placed adjacent to the operating lever and that, when pressed, detaches the gas socket from the plug via the interlocking body. The closure can be opened and closed using an operating lever, and the gas socket can be removed using a release push button.The opening/closing of the closure and the release of the gas socket can be done using separate operating levers and release push buttons, making handling easier than before. It is easy to open and close the closure, and the structure for opening and closing the closure and disconnecting the gas socket is simple.Furthermore, the closure can be opened and closed by swinging the operating lever, making it easier to open and close the closure compared to conventional ones. It is easy to operate, and has a safety mechanism that allows the release push button to be pressed when the operating lever is closed and prevents the release push button from being pressed when the operating lever is open. It is extremely safe because the gas socket can only be removed from the gas socket, and the safety mechanism that allows the release push button to be pressed when the operating lever is closed and prevents the release push button from being pressed when the operating lever is open is the release push button. It consists of a protrusion that protrudes in the direction in which the release push button is pressed on the operating lever side surface, an interlocking section that is integrally provided at the base of the operating lever, and a notch on the interlocking section, which allows the operating lever to be in the closed state. Only when the protrusion and the notch match, it is possible to press the release push button, and at the same time, when the operation lever is not in the closed state, the protrusion hits the interlocking part and does not allow the release push button to be pressed. Taking advantage of the feature of opening and closing the gas tank by swinging the operating lever, the gas tank can be opened and closed with a simple structure that includes a notch in the interlocking part integrated into the operating lever and a protrusion on the release push button. The structure is such that the gas socket can be removed from the plug, and the gas socket cannot be opened or closed unless the gas socket is attached to the plug.The structure is simple, there are few breakdowns, and the operation is reliable and highly safe. Hold the top surface of the interlocking part of the safety mechanism with a presser spring piece, so that the locking protrusion on the top surface of the interlocking part can lock into the pair of locking holes provided in the presser spring piece when the operating lever is in the open and closed positions. Therefore, when opening and closing the gas kettle by rotating the operating lever, the closed and open positions of the gas kettle can be confirmed by the locking between the locking hole and the locking protrusion, and when opening the gas kettle, it is possible to confirm the closed and open positions of the gas kettle. It is possible to fully open the gas tank when closing it, and it is also possible to press the release push button after confirming the closed position of the operating lever, and to press the release push button even though the operating lever is not in the closed state. There is no need to make such erroneous operations.
