A decorative board covering the opening is attached and fixed to the surface of the wall or floor,
The decorative plate is provided with a window portion through which the socket can be inserted, and an opening / closing lid for opening and closing the window portion,
The open / close lid is pivotally supported between a closed posture for closing the window portion and an upright open posture rotated 90 degrees from the closed posture, and is pushed in with the upright open posture. Can be moved to
In the socket removal device for an embedded gas plug of the type in which the release lever mounted in the vicinity of the base end portion of the plug portion is released by pushing the opening / closing lid and the socket is removed from the plug portion '' Even if the distance from the opening to the attachment position of the gas stopper changes, it is an object to reliably perform the release operation of the release lever without increasing the size of the opening / closing lid and the decorative plate.

(1) According to the first aspect of the present invention, there is provided a device for removing a socket of an embedded gas plug according to the invention, wherein “the release lever is operated via a length adjusting member that is pushed together with the opening / closing lid,
The length adjusting member includes a movable member that is pivotally supported by the opening / closing lid and is movable in the pushing direction together with the opening / closing lid, and is connected to the moving member and has one end close to the operation portion of the release lever. Alternatively, the length of the pushing direction includes a stretchable member that can be stretched and contracted so as to be in contact with each other ”.

The above means operates as follows.
The length adjusting member includes a moving member and a telescopic member, and the opening / closing lid is pivotally supported by the moving member. Therefore, when the opening / closing lid is rotated, the posture of the length adjusting member does not change, and when the opening / closing lid in the upright open posture is pushed into the back side of the decorative plate, the moving member also moves in the pushing direction together with the opening / closing lid. At the same time, the elastic member connected to the moving member also moves in the pushing direction.

  Since the length of the expansion / contraction member in the push-in direction can be adjusted, the length of the expansion / contraction member can be adjusted so that one end of the expansion / contraction member comes close to or abuts on the operation portion of the release lever. Thus, when the opening / closing lid is pushed in, the expansion / contraction member is moved in the pushing direction together with the opening / closing lid, and the operation portion of the release lever is pushed by one end of the expansion / contraction member, and the release operation is executed. That is, one end of the elastic member functions as a conventional pushing end.

  Since the opening / closing lid is pivotally supported by the moving member, the length adjustment member does not rotate at the same time as the opening / closing lid, even if the opening / closing lid in the upright open position is closed. The posture of the member is kept constant.

  (2) The invention according to claim 2 is the buried gas plug socket detaching device according to claim 1, wherein the expansion / contraction member is adjustable from the window portion in the open state. When the opening / closing lid is in an upright open posture, a length adjusting member is installed so that the elastic member is exposed from the window, and the exposed portion is operated to adjust the length of the elastic member. Can be adjusted.

(3) The invention according to claim 3 is the socket removal device for the buried gas plug according to claim 1 or 2,

The other end of the female screw cylinder member is in contact with or connected to the operation portion of the release lever in a non-rotating state ”, and the length of the expansion / contraction member is such that the male screw member extends from one end of the female screw cylinder member. It is determined by the degree of screwing. Since the other end of the female screw cylinder member is in contact with or connected to the operation portion of the release lever in a non-rotating state, the male screw member is screwed or loosened to remove the male screw member from one end of the female screw cylinder member. A predetermined length can be projected. When the open / close lid in the upright open position is pushed in, the operation portion of the release lever is pushed by the other end of the female screw cylinder member to be released. In this case, the other end of the female screw cylinder member functions as the pushing end.

(4) The invention according to claim 4 is the embedded gas stopper socket detaching device according to claim 3, wherein the female screw cylinder member is open at both ends and a hook portion is stretched at one of the open ends. In the posture of either the first posture in which the one open end faces the opening side or the second posture in which the other open end faces the opening side, The part is in contact with or connected to the operation part of the release lever in a non-rotating state,
The male screw member can be screwed from any open end of the female screw cylinder member ”, and in the case of the first posture, the female screw cylinder member is located behind the operation portion of the release lever. And the male screw member is screwed from the one open end. In the case of the second posture, the body portion of the female screw cylinder member protrudes in front of the operation portion of the release lever, and the male screw member is screwed from the other open end. The former can be applied when the distance from the opening to the mounting position of the gas plug is short, and the latter can be applied when the distance is long, and the mounting posture of the female screw cylinder member to the operating portion of the release lever can be switched. Thus, the expansion and contraction can be adjusted within a range of about twice the entire length of the female screw cylinder member.

  As described above, according to the first aspect of the present invention, the length of the expansion / contraction member of the length adjusting member is set according to the distance from the opening provided on the wall or floor to the attachment position of the gas stopper. Since the operating part can be adjusted to a length that allows the release operation, the opening / closing lid in an upright open position can be used even if the installation position of the gas stopper is changed and the distance from the wall or floor to the gas stopper is changed. The socket can be removed simply by pushing.

  The length adjustment member moves in the push-in direction together with the opening / closing lid, but is not related to the rotation of the opening / closing lid. Therefore, the expansion / contraction member of the length adjustment member is not limited to the size of the opening / closing lid. Can be set to a length of In other words, even if the length of the expansion / contraction member is set longer, there is no need to change the size of the opening / closing lid and the decorative plate. is there.

  Since the rotation shaft of the opening / closing lid is pivotally supported by the length adjusting member, the length adjusting member is provided on the decorative board side where the opening / closing lid is provided. Therefore, compared with the length adjustment member provided on the gas stopper side, when the gas stopper is embedded and fixed, there is no hindrance to the construction, and the length adjustment member does not need to be protected. There is no damage.

  According to the invention which concerns on Claim 2, in addition to the said effect, there exists an effect that the length adjustment of the expansion-contraction member of a length adjustment member is easy.

Become.

  According to the fourth aspect of the present invention, by switching the mounting posture of the female screw cylinder member from the first posture to the second posture, the length of the female screw cylinder member is about 2 times. Since the expansion / contraction adjustment for the double length is possible, the lengths of the female screw cylinder member and the male screw member can be shortened. The cost can be reduced accordingly. In addition, since the expansion / contraction range of the expansion / contraction member is expanded by switching the posture of the female screw cylinder member, even if the distance from the wall or floor to the installation position of the gas plug becomes shorter than the conventional one by replacing the gas plug, etc. Even if the length is increased, the length of the telescopic member can be reliably adjusted in accordance with the position of the operating portion of the release lever attached to the gas stopper.
