JP 2005-180685 A

However, the conventional protective cap has a simple shape with a bottomed cylindrical shape as a whole and can be inserted into the socket insertion / removal opening 31a of the front cover 30, so that it is protected by the plug 2 of the gas outlet. It was possible to attach the front cover 30 with the cap on (refer to FIG. 3 of the present application for the figure number attached to this sentence. FIG. 3 of the present application used the protective cap of the present application. The state is shown, but for ease of understanding, the corresponding part numbers are indicated.)
Therefore, where the front cover should be attached after removing the protective cap, the operator may accidentally attach the front cover to the surface side of the wall surface forming material with the protective cap covered.
If you attach the front cover with the protective cap on, then it is very difficult to remove the protective cap, and if you try to remove it forcibly, there is a risk of damaging the front cover. After removing the protective cap and removing the protective cap, the troublesome work of attaching the front cover again was required, and this point had a problem.

  The present invention has been made in view of such a situation, and an object of the present invention is to protect a gas outlet that can prevent the occurrence of a situation in which a front cover is attached with the protective cap on the gas outlet. To provide a cap.

A protective cap for a gas outlet according to the present invention includes a plug to which a socket is detachably connected, and a release lever positioned on a side of the plug to release a socket connection state in which the socket is connected to the plug. For covering a gas outlet attached to the back side of the wall surface forming material in a state facing the opening formed in the wall surface forming material,

An engaging portion for preventing the plug from being detached is integrally provided, and the engaging portion includes a front cover provided with a socket insertion / removal opening for inserting / removing the socket so as to cover the opening. When attached to the surface side of the wall surface forming material, it is configured to function as an interference part that interferes with the interfered part provided on the front cover and prevents the attachment of the front cover to the wall surface forming material. There is in point.

According to the above characteristic configuration, since the bottomed cylindrical cap main body portion that covers the plug is provided, the plug of the gas outlet to which the socket is connected can be reliably protected as in the conventional case.
In addition, the cap body is integrally provided with an engaging portion that engages with the lever of the gas outlet and prevents the cap body from being detached from the plug when the cap body is covered with the plug of the gas outlet. Therefore, when the protective cap is put on the gas outlet, the engaging part engages with the lever release, making it difficult for the protective cap to be detached from the gas outlet. Even if another object hits the protective cap, the situation in which the protective cap easily separates from the gas outlet is suppressed.
And when the front cover provided with the socket insertion / removal opening is attached to the surface side of the wall surface forming material so as to cover the opening of the wall surface forming material, the engaging portion to the release lever is provided on the front cover. It is configured to function as an interference part that interferes with the interfered part and prevents the attachment of the front cover to the wall surface forming material, so it is impossible to attach the front cover with the protective cap on the gas outlet It is possible to prevent the occurrence of a situation where the front cover is attached accidentally with the protective cap covered, and the engaging portion to the lever release has the function of engaging the protective cap with the gas outlet and the front cover. Therefore, the structure can be simplified by sharing the functions.
In addition, since the protective cap is engaged with the lever release, when the gas outlet is assembled, if the lever is forgotten to be assembled or if the assembled state is defective, the protective cap will be engaged even if the protective cap is put on the gas outlet. I can't.
Therefore, when the protective cap is attached at the manufacturing stage, it is possible to detect an improper attachment of the lever release.

  In the second feature configuration, in addition to the first feature configuration described above, the operation portion of the lever release is configured as a bifurcated bifurcated operation portion having a notch on the side away from the plug, and the operation of the lever release A lever cover portion covering at least the tip end side of the plug in the portion includes a pair of cover portions covering the bifurcated operation portion, and the pair of cover portions are provided to project to the side of the cap body portion, A hook-like body that engages with the release lever is provided as the engaging portion, and the hook-like body passes through the notch portion with its longitudinal direction along the axis of the cap main body portion. In addition to being configured to engage with the notch, the release operation portion at the end portion on the front end side of the cap body portion in the bowl-shaped body is configured to function as the interference portion.

According to the above characteristic configuration, when the protective cap is put on the gas outlet, the pair of cover portions of the lever cover portion covers at least the plug tip side of the bifurcated operation portion, and the cutout portion of the bifurcated operation portion The state body is caught and the removal of the protective cap from the gas outlet is suppressed.
In other words, the lever cover portion is provided with a pair of cover portions that cover the bifurcated operation portion, and the hook-like body that engages with the release lever has a longitudinal direction between the pair of cover portions along the axis of the cap body portion. In the posture that passes through, it will be supported by a pair of cover parts at the middle part in the longitudinal direction, and even if the operating part of the lever release is a bifurcated operating part, the bifurcated operating part can be covered accurately And the protective cap provided with the hook-shaped body can be comprised compactly.
And since the release operation part of the front end side end part of the cap main body part in the bowl-like body functions as an interference part that interferes with the interfered part of the front cover, the bowl-like body is a gas outlet. The function of engaging the front cover and the function of interfering with the front cover are shared, and the structure can be simplified by sharing the function.

Further, the protective cap for a gas outlet according to the present invention includes a plug to which a socket is detachably connected, and a detachment located on a side of the plug in order to release a socket connection state in which the socket is connected to the plug. Comprising a lever, for covering a gas outlet attached to the back side of the wall surface forming material in a state facing the opening formed in the wall surface forming material,
The characteristic configuration is that the bottomed cylindrical cap main body portion covering the plug includes a flange portion at the bottomed cylindrical tube shaft end portion, and the flange portion inserts the socket into and out of the socket. When a front cover having a removal opening is attached to the surface side of the wall surface forming material so as to cover the opening, the wall surface forming material of the front cover interferes with an interfered portion provided in the front cover. It is in the point comprised so that it may function as an interference part which prevents the attachment to.

According to the above characteristic configuration, as with the first characteristic configuration described above, the bottomed cylindrical cap body portion can reliably protect the plug of the gas outlet to which the socket is connected, and the bottomed cylinder. The cap body portion has a flange portion at the bottom end of the cylindrical tube shaft, that is, the proximal end portion or the distal end portion of the cap body portion, or both end portions of the proximal end side and the distal end side. Therefore, the cap main body is reinforced by the flange portion.
And the flange part provided in the base end side end part or the tip end part of the cap main body part is a surface of the wall surface forming material so that the front cover provided with the socket insertion / removal opening covers the opening part of the wall surface forming material. When it is attached to the side, it is configured to function as an interference part that interferes with the interfered part provided on the front cover and prevents the front cover from being attached to the wall surface forming material. Since both the function of reinforcing the cap body and the function of interfering with the front cover are provided, the structure can be simplified by combining the functions.

In the state located in the bottom part side, it is provided ranging over each cover part 10a and the cap main-body part 8. FIG.
The entire protective cap 7, that is, the cap main body 8, the flange 9, the lever cover 10, the connecting part 12, the rib 13, the bowl-shaped body 14, and the swing member 15 is flexible silicon. It is integrally formed so as to have elasticity by resin molding with a soft resin such as resin.

The protective cap 7 configured as described above attaches the front cover 30 after the gas outlet 1 is attached to the back surface of the wall surface forming material W as well as during storage of the gas outlet 1 and transportation to the installation location. In the meantime, as shown in FIG. 3, the gas outlet 1 is left covered to protect against contact with other objects and adhesion of dust.
Finally, the protective cap 7 is removed from the gas outlet 1 and the front cover 30 is attached. As shown in FIGS. 3 and 4, the front cover 30 is attached to the front side frame body with the protective cap 7 covered. 21, the release operation portion 14 b of the rod-shaped body 14 as the interference portion A provided in the protective cap 7 interferes with the push-in member 35 as the interference portion B provided in the front cover 30. Thus, the attachment of the front cover 30 to the wall surface forming material W is prevented. Accordingly, it is possible to avoid attaching the front cover 30 by mistake while the protective cap 7 is put on.

In order to put the protective cap 7 on the gas outlet 1, for example, the gas cap 1 is held with a pair of ribs 13 sandwiched between the thumb and forefinger, and the collar 14 a at the tip of the collar 14 passes between the bifurcated operation parts 5 a. Push into outlet 1. Then, due to the elastic deformation of the swing member 15, the flange portion 14 a is hooked and engaged with the connecting portion 5 c of the release lever 5, and the protective cap 7 is attached to the gas outlet 1.
As described above, since the protective cap 7 is configured to be engaged with the connecting portion 5c of the release lever 5, when the gas outlet 1 is assembled, if the release lever 5 is forgotten to be assembled or the assembled state is defective, the protective cap 7 is removed. Even if it covers the gas outlet 1, the lever 5 cannot be engaged, so that it is possible to detect a mounting failure of the lever 5 when the protective cap 7 is mounted in the manufacturing stage.
Conversely, to remove the protective cap 7 from the gas outlet 1, the pair of ribs 13 is sandwiched between the thumb and the middle finger, and the release operation portion 14 b of the hook-like body 14 is pulled forward with the index finger, thereby connecting the hook portion 14 a and the connecting portion. Since the engagement with 5c is released, the protective cap 7 can be easily removed by pulling the protective cap 7 forward.

[Another embodiment]
Next, another embodiment will be described.
However, in another embodiment shown in FIG. 11 and FIG. 12, in order to avoid redundant description, the same reference numerals are given to the component parts described in the previous embodiment, and the description is omitted, which is mainly different from the previous embodiment. The configuration will be described.

(A) In the previous embodiment, the release operation portion 14b of the bowl-shaped body 14 functions as the interference portion A. However, as shown in FIG. The flange portion 9 provided at the end portion may be a large-diameter flange portion, and the large-diameter flange portion 9 located at the proximal end side end portion may function as the interference portion A.
However, in that case, the cylindrical portion 31 or the guide portion 34 on the front cover 30 side is greatly protruded toward the back side of the front cover 30, and the cylindrical portion 31 or the guide portion 34 functions as the interfered portion B. It will be configured as follows.
Furthermore, as shown in FIG. 12, in addition to the flange portion 9 at the base end side end portion of the cylinder shaft in the cap main body portion 8, a flange portion 9 is also provided at the end portion on the distal end side of the tube shaft, It is also possible to configure so that the flange portion 9 functions as the interference portion A. Also in this case, the cylindrical portion 31 or the guide portion 34 on the front cover 30 side functions as the interfered portion B.

(B) In the previous embodiment, an example was shown in which the tongue piece 10b of the lever cover 10 formed the contact portion that rotates together with the release lever 5 when the release lever 5 is rotated. A contact portion that enters between the operation portions 5a may be provided on the protective cap 7 so that the contact portion contacts the inside of the bifurcated operation portion 5a and rotates together.
However, the shape of the operating portion of the lever 5 is not necessarily bifurcated. For example, it can be a wide plate, and in this case, the tongue that contacts the outside of the plate-like operating portion. The contact portion is constituted by the piece 10b.
In the previous embodiment, an example in which the release lever 5 is configured to be rotatable around the plug 2 has been described. However, the embodiment is also applied to a gas outlet in which the release lever 5 is not rotatable around the plug 2. In addition, an example in which the entire protective cap 7 is made of a resin molded product made of silicon resin has been shown. For example, the cap body 8 and the lever cover 10 are formed separately, and both of them are made of an adhesive or the like. It can also be implemented by connecting.

  As described above, it is possible to provide a protective cap for a gas outlet that can prevent the occurrence of a situation in which the front cover is attached while the protective cap is put on the gas outlet.
