As shown in FIGS. 1 and 5, the peripheral wall 41 of the fixed case 4 has a main portion 41a and a sub portion 41b connected to the lower end of the main portion 41a. The cross-sectional shape of the sub portion 41b is U-shaped (or U-shaped) smaller than that of the main portion 41a. A step 41c corresponding to the thickness of the peripheral wall 51 of the movable case 5, which will be described later, is formed at the boundary between the main portion 41a and the sub portion 41b.

As shown in FIG. 5, the fixed case 4 is further formed with a pair of guide portions 45 adjacent to the pair of left and right hanging portions 43 and extending along the hanging portion 43. These pair of guide portions 45 are retracted inward from the hanging portion 43 and are flush with the sub portion 41b of the peripheral wall 41. The outer surface of the hanging portion 43 is flush with the main portion 41a of the peripheral wall 41.

As shown in FIGS. 1B and 5, the movable case 5 is arranged inside the peripheral wall 51, which is connected to the peripheral wall 51 having a U-shaped (or U-shaped) cross section and the lower end edge of the peripheral wall 51. It has an inner wall 52 having a semi-cylindrical cross section and a pressing portion 53 protruding inward in the radial direction from the upper end of the inner wall 52. The inner diameter of the inner wall 52 is larger than the outer diameter of the socket 6. The pressing portion 53 has a semi-circular shape (arc shape) corresponding to the advancing / retreating sleeve 61 of the socket 6.

The movable case 5 is arranged on the plug portion 32 side of the fixed case 4. The peripheral wall 51 of the movable case 5 covers the front surface and both side surfaces of the plug portion 32 of the gas plug 3.
The outer surface of the peripheral wall 51 of the movable case 5 is flush with the main portion 41a and the hanging portion 43 of the peripheral wall 41 of the fixed case 4. The inner surface of the upper end portion of the peripheral wall 51 of the movable case 5 is in contact with the outer surface of the sub portion 41b of the fixed case 4, and the inner surfaces of both side portions of the peripheral wall 51 are in contact with the outer surface of the guide portion 45.

As shown in FIG. 6, both side portions of the peripheral wall 51 of the movable case 5 are slidably supported by the fixed case 4 in the vertical direction (axial direction of the plug portion 32) by a pair of guide means G. The pair of guide means G is composed of a guide groove 48 formed in the pair of guide portions 45 and a pair of slide portions 58 projecting inward from the end edges of both side portions of the peripheral wall 51 of the movable case 5.

As shown in FIG. 5, the guide groove 48 and the slide portion 58 extend in the vertical direction. As shown in FIG. 8, the pair of slide portions 58 can be fitted into the pair of guide grooves 48 by utilizing the elasticity of the fixed case 4 and the movable case. Since the tip of the slide portion 58 is rounded, it is easy to fit the slide portion 58 into the guide groove 48.

As shown in FIG. 6, since the slide portion 58 is shorter than the guide groove 48, the guide groove 48 can be moved, whereby the movable case 5 can slide with respect to the fixed case 4. Within the range of the sliding stroke of the movable case 5, the peripheral wall 51 of the movable case 5 does not come off from the sub portion 41b of the peripheral wall 41 of the fixed case 4, and these peripheral walls 41 and 51 continuously cover the gas plug 3.

Next, connection and disconnection between the socket 6 and the plug portion 32 of the gas plug 3 will be described.
As shown in FIGS. 1, 4, and 6 (A), when the socket 6 is not connected to the plug portion 32, the movable case 5 is in the lower reference position due to its own weight, and this reference position is the slide portion 58.

At this reference position, the upper end of the peripheral wall 51 of the movable case 5 is separated from the step 41c of the peripheral wall 41 of the fixed case 4.

To connect the socket 6 to the plug portion 32, the socket 6 is moved upward from the lower end of the movable case 5. Then, the advancing / retreating sleeve 61 of the socket 6 at the initial position comes into contact with the pressing portion 53 of the movable case 5 and pushes up the movable case 5. When the socket 6 is further moved upward together with the movable case 5, the socket 6 is externally inserted into the plug portion 32 up to the connection position. Then, the advancing / retreating sleeve 61 protrudes upward, and the socket 6 and the plug portion 32 are engaged with each other.

As described above, in the state where the socket 6 is connected to the plug portion 32 and the advancing / retreating sleeve 61 protrudes upward, the upper end of the peripheral wall 51 of the movable case 5 touches or slightly touches the step 41c of the peripheral wall 41 of the fixed case 4. They are facing each other through a gap.

When removing the socket 6 from the plug portion 32 of the gas plug 3, the movable case 5 is grasped and pushed down. At this time, the advancing / retreating sleeve 61 of the socket 6 is pressed by the pressing portion 53 of the movable case 5 and retracts to the initial position. As a result, the engagement between the socket 6 and the plug portion 32 is released, and the socket 6 is disengaged from the plug portion 32.
As described above, the socket 6 can be easily removed by simply grasping and pushing down the movable case 5 exposed to the outside. Moreover, since the operation direction of the movable case 5 is the same as the direction in which the socket 6 is removed, the removal operation is easy to understand.

Next, other embodiments of the present invention will be described. In the following embodiments, only configurations different from those of the above embodiments will be described, and the same components will be designated by the same reference numerals and the description thereof will be omitted.

[Fifth Embodiment]
FIG. 12 shows a fixed case 4 and a movable case 5 used in a gas outlet device (not shown, but designated by reference numeral 1D for convenience of explanation) according to a fifth embodiment of the present invention. Unlike the first embodiment, the gas outlet device 1D includes a torsion coil spring 8 (a urging means) for urging the movable case 5 between the fixed case 4 and the movable case 5.

A pair of torsion coil springs 8 are arranged inside both side portions of the assembled fixed case 4 and movable case 5. Both one end 81 and the other end 82 of the torsion coil spring 8 are bent in an annular shape. As shown in FIGS. 12 and 13A, a concave first spring receiver 49 that opens toward the movable case 5 is formed on the lower end surfaces of both side portions of the sub portion 41b of the fixed case 4. Further, as shown in FIGS. 12 and 13B, a second spring receiver 59 having a recess that opens toward the fixed case 4 is provided inside both side portions of the peripheral wall 51 of the movable case 5. ..

In a state where the torsion coil spring 8 is twisted in the winding direction, one end 81 is accommodated in the first spring receiver 49 and locked, and the other end 82 is accommodated and locked in the second spring receiver 59. ing. Therefore, the torsion coil spring 8 exerts an urging force on the movable case 5 in the downward direction, that is, in the direction opposite to the connection direction of the socket to the plug portion 32 (see FIG. 7B). As a result, when the socket is removed, as shown in FIG. 12A, the movable case 5 is always guided to the reference position where the slide portion 58 of the movable case 58 hits the lower end 48a of the guide groove 48.

When the socket is attached to the plug portion 32, the movable case 5 is in the upper position as shown in FIG. 12 (B). Since the urging force of the torsion coil spring 8 acting on the movable case 5 is set to be weaker than the force required to remove the socket, the socket is not removed by the urging force of the torsion coil spring 8. The configuration of the gas outlet device 1D other than the above configuration is the same as the configuration of the gas outlet device 1 of the first embodiment. Therefore, the description of configurations other than the above configurations will be omitted.

In this embodiment, by providing the torsion coil spring 8 as the urging means, the movable case 5 can always be arranged at the reference position when the socket is removed from the plug portion 32. As a result, the movable case 5 can sufficiently cover and protect the plug portion 32 of the gas plug 3. In particular, when the gas outlet device 1D is installed with the tip of the plug portion 32 facing other than directly below, when the socket is removed, the restoring force (force leading to the reference position) due to its own weight acts on the movable case 5. It may not work or may not work well. As a result, the movable case 5 may stop before reaching the reference position, so it is effective to provide an urging means.

In this embodiment, the torsion coil spring 8 (the urging means) is provided by locking the fixed case 4 and the movable case 5 constituting the fixed structure, as in the second embodiment. In addition, it can also be provided in a gas outlet device in which a fixed structure is formed only by a mounting plate. In that case, one end of the torsion coil spring may be locked to the mounting plate, and the other end may be locked to the movable case.
In this embodiment, a torsion coil spring is used as the urging means, but an elastic body such as a leaf spring or a push spring may be used.

The present invention is not limited to the above embodiment, and various modifications can be adopted without departing from the gist thereof.
In the first and second embodiments, the pressing portion may form an annular shape corresponding to the advancing / retreating sleeve.
In all embodiments, the guide means may consist of a guide groove formed in the movable case and a slide portion formed in the fixed structure.

The present invention can be applied to a gas outlet device installed on a wall or the like.
