JP6039943B2 - Buried gas plug - Google Patents

Description

  The present invention relates to a buried gas plug provided on a wall component including a wall plate or a floor component including a floor plate.

  Conventionally, there is an underfloor buried type gas stopper as one of buried type gas stoppers. The underfloor buried type gas stopper has a gas stopper main body. The gas plug main body has a plug portion, and is arranged on the lower side of the floor board with the plug portion facing upward. A through hole facing the plug portion is formed in the floor board. A socket is inserted from the through hole and connected to the plug portion.

The gas stopper main body is provided with a removing member. The removal member is located at the removal position in a state where the socket is not connected to the plug portion, and is moved from the removal position to the attachment position by the socket when the plug portion socket is connected.

  The gas stopper main body is provided with an operation member that is manually operated through a through hole. When the operating member is pushed downward, the removal member is moved from the attachment position to the removal position, thereby releasing the connection state of the socket to the plug portion. Therefore, the socket can be removed from the plug portion.

  By the way, the distance from the upper surface of the floor plate to the operation member is determined by the attachment position of the gas stopper main body, and the attachment position of the gas stopper main body changes depending on the position of the gas pipe connected to the gas stopper main body. . When the attachment position of the gas plug main body is below the normal attachment position, the operation member is greatly separated downward from the upper surface of the floor board. As a result, it becomes difficult to push down the operation member. On the contrary, if the mounting position of the gas plug main body is above the normal mounting position, the operation member hits the decorative plate covering the through hole of the floor plate and the vicinity thereof, and the decorative plate cannot be attached to the floor plate. There is a fear.

  In order to eliminate such an inconvenience, in the thing of the following patent document 1, the screw member which orient | assigned the longitudinal direction to the up-down direction was provided in the gas stopper main body, and the operation member is screwed together to this screw member. . Therefore, the operation member can be adjusted in the vertical direction by appropriately rotating in the forward and reverse directions with respect to the screw member, thereby absorbing the change in the mounting position of the gas plug main body.

JP-A-2004-205015

  The underfloor buried gas plug described in Patent Document 1 requires a screw member for position adjustment, and the number of parts increases accordingly. For this reason, there has been a problem that the manufacturing cost of the gas stopper becomes high. Further, it is necessary to rotate the operation member with respect to the screw member. In this case, if the periphery of the operation member is open, the operation member can be easily rotated, but the operation member is disposed in a through hole formed in the floor plate. In addition, the through hole is formed as small as possible. For this reason, there is a problem that it is difficult to rotate the operation member, and that much time is required to adjust the position of the operation member. Such a problem also applies to the buried type gas stopper disposed on the outdoor side with respect to the wall plate.

In order to solve the above problems, the present invention provides a gas plug main body disposed on the outdoor side with respect to a wall plate or a floor plate, the gas plug main body, a wall constituent member including the wall plate, or the floor plate. A fixing means for fixing to a constituent member of the floor including the plug portion, which is provided in the gas plug main body, and is detachably connected to a socket inserted from the indoor side into a through hole formed in the wall plate or the floor plate. A removal member for releasing the connection of the socket connected to the plug portion, and an operation member provided in the gas plug body so as to be movable indoors and outdoors in order to release the removal member. When the socket is connected to the plug portion, the removal member is displaced from the removal position to the attachment position, and accordingly, the operation member is displaced from the push-in position to the initial position from the outdoor side toward the indoor side. The plug When the operation member is pushed from the initial position toward the push-in position toward the outdoor side with the socket connected to the socket, the removal member is displaced from the attachment position to the removal position. Accordingly, the socket is an embedded gas plug that is disconnected from the plug portion, and has a sub operation member that is detachably attached to the operation member from the room through the through hole.
In this case, a positioning recess is formed on the surface facing the outdoor side of the sub operation member, and the end of the operation member on the indoor side is detachable in the indoor / outdoor direction and is orthogonal to the indoor / outdoor direction. It is desirable that the fitting is impossible.
A plurality of the sub operation members may be used. In this case, a plurality of sub operation members are sequentially arranged in the indoor / outdoor direction, and the sub operation members are arranged on the surface facing the indoor side of each sub operation member. On the other hand, the positioning recesses of the other sub-operation members adjacent to the indoor side are provided with protrusions that are detachable in the indoor / outdoor direction and that cannot move in the direction orthogonal to the indoor / outdoor direction. desirable.
It is desirable that the projecting portion is disposed at the same position in the horizontal direction as the upper end portion of the operation member fitted into the positioning recess.
A surface of the wall plate or the floor plate facing the room is detachably provided with a decorative plate that covers the through hole of the wall plate or the floor plate and the vicinity thereof, and the auxiliary operation member is provided on the decorative plate. It is desirable to provide a guide portion that can move in the indoor and outdoor directions and that cannot move in the direction orthogonal to the indoor and outdoor directions.
The cover further includes a cover portion that is detachably attached to the plug portion with its distal end covered, and a deformable elongated connection portion having a base end portion connected to the cover portion. And it is desirable for the front-end | tip part of the said connection part to be connected with the said sub operation member.
The cover further includes a cover portion that is detachably attached to the plug portion with its distal end covered, and a deformable elongated connection portion having a base end portion connected to the cover portion. A support member that is a separate member is attached to the gas plug body, the operation member is provided on the support member so as to be movable in the indoor and outdoor directions, and the distal end of the connecting portion is attached to the support member. It is desirable to be connected.

According to the present invention having the above characteristic configuration, since the sub operation member is provided on the operation member, the sub operation member is pushed to the outdoor side when the socket is removed from the plug. Here, the position of the surface on the outdoor side of the sub-operating member changes according to the installation position of the gas stopper main body, but if the installation position of the gas stopper main body is outside the predetermined position, the sub-operating member When a secondary operation member having a high height (large dimension in the indoor / outdoor direction) is used and the installation position of the gas stopper body is on the indoor side from a predetermined position, the secondary operation member has a low height (in the indoor / outdoor direction). Use a sub-operation member (small size). Thereby, the indoor side surface of the sub-operation member can be positioned at a position where it can be easily operated. In addition, since the sub operation member is merely brought into contact with the operation member, a rotation operation as in the case of using a screw member is not required. Therefore, the labor required for installing the gas stopper can be reduced. Moreover, since the screw member is unnecessary, the manufacturing cost of the gas stopper can be reduced accordingly.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 21 show a first embodiment of the present invention. In this embodiment, the present invention is applied to an underfloor buried gas plug (buried gas plug). Therefore, first, the structure of the floor portion of the building where the underfloor gas plug is installed will be briefly described. As shown in FIGS. 1 to 3, the joists (not shown; floor components) arranged horizontally. The floor board F is mounted and fixed on the top. A through hole Fa that penetrates the floor plate F in the vertical direction (inside and outside) is formed at an appropriate location of the floor plate F. The through hole Fa has a circular cross section, but may be a non-circular shape such as a square cross section.

Next, the underfloor buried type gas stopper according to the present invention will be described. As shown in FIGS. 1 to 3 and 9, the underfloor buried gas plug 1 of this embodiment has a gas plug body 2, a cover 3, a removal unit 4, a sub operation button (sub operation member) 5, and an attachment. A board 6 and a decorative board 7 are provided.

The gas plug main body 2 has a gas pipe connecting portion 21 and a plug portion 22 as shown in FIGS. 1 to 3, 8 and 9 in particular. A gas passage 23 (see FIG. 9) extending from the distal end surface of the gas pipe connecting portion 21 to the distal end surface of the plug portion 22 is formed in the gas plug body 2. A gas pipe (not shown) on the primary side (supply side) is connected to the gas pipe connecting portion 21 by screwing or other connecting means. Gas is supplied from this gas pipe to the gas passage 23. On the other hand, the plug portion 22 has a shape and dimension defined by Japanese Industrial Standards (JIS S2120), and is provided with its tip surface facing upward (inside the room I). A socket S is detachably attached to the plug portion 22.

An open / close valve (not shown) is provided inside the gas stopper body 2. The on-off valve opens the gas passage 23 when the socket S is connected to the plug portion 22. As a result, the gas flowing into the gas passage 23 from the primary side gas pipe is supplied to the gas appliance (not shown) via the socket S and the secondary side gas pipe (not shown). The on-off valve automatically closes the gas passage 23 when the socket S is removed from the plug portion 22.

As shown in FIGS. 1 to 3 and 9, the cover 3 has a bottomed cylindrical shape, with its bottom positioned on the lower side (outdoor O side) and its opening positioned on the upper side. Has been placed. The upper end part of the cover 3 is inserted in the lower end part of the through-hole Fa so that insertion or removal is possible. The entire cover 3 may be arranged below the floor board F without the upper end of the cover 3 being inserted into the through hole Fa.

On the outer peripheral surface of the cover 3, two flat portions 31 are formed 180 degrees apart in the circumferential direction. By forming these two flat portions 31, the cover 3 is actually in the shape of an ellipse in plan view. A wood screw (not shown) is inserted into the flat portion 31 from the inside of the cover 3, and by screwing the wood screw into the joist and tightening, the flat portion 31 is pressed and fixed to the side face of the joist, and as a result, the cover 3 is It is fixed to joists.

A gas plug body 2 is accommodated in the cover 3. The gas stopper main body 2 is fixed to the cover 3 by screws or other fixing means (not shown). As a result, the gas stopper main body 2 is supported by the joist through the cover 3. As described above, the gas plug body 2 is connected to the primary side gas pipe and is also supported by the gas pipe. When the support strength of the gas pipe is high, it is not always necessary to fix the cover 3 to the joist. Conversely, when the cover 3 is fixed to the joist, a gas pipe with low rigidity may be employed as the primary side gas pipe. For example, a flexible gas pipe may be adopted as the primary side gas pipe. When the gas plug main body 2 is supported by the gas pipe and the cover 3 is fixed to the joist, if there is a large gap between the joist and the flat portion 31, a spacer is fixed to the joist. What is necessary is just to fix the flat part 31 to.

As is apparent from the fact that the gas plug main body 2 is accommodated in the cover 3 and the upper end portion of the cover 3 is inserted into the through hole Fa, the plug portion 22 of the gas plug main body 2 is viewed from above. These are disposed so as to be located in the through hole Fa. Moreover, in the gas plug 1, the distal end portion (upper end portion) of the plug portion 22 protrudes upward from the cover 3 and enters the lower end portion of the through hole Fa. The distal end portion of the plug portion 22 may be positioned below the upper end of the cover 3 so as not to enter the through hole Fa. A notch 32 is formed at the lower end of the cover 3. The gas pipe connecting portion 21 is projected outside the cover 3 through the notch 32.

The removal unit 4 has a unit main body 41 as shown in FIGS. 9 and 10 in particular. The unit main body 41 is accommodated in the cover 3 and fixed to the gas stopper main body 2 with screws B1 and B1. A cylindrical portion 42 is formed at one end of the unit body 41 in the horizontal direction (the right end in FIGS. 1 to 3; the left end in FIG. 9). The cylindrical portion 42 is disposed with its axis line directed in the vertical direction. Inside the cylindrical portion 42, the plug portion 22 is inserted in a state where the axis thereof coincides with the axial line of the cylindrical portion 42. A socket S connected to the plug portion 22 is inserted into the tube portion 42. Therefore, the cylindrical portion 42 has an inner diameter larger than the maximum outer diameter of the socket S so that the socket S can be inserted and removed from the upper end opening.

In particular, as shown in FIGS. 11, 14, and 15, a guide hole 43 is formed at the other end of the unit body 41 in the horizontal direction. The guide hole 43 has a substantially rectangular cross section, and penetrates the other end of the unit body 41 in the vertical direction. An operation button (operation member) 44 is inserted into the guide hole 43 so as to be movable in the vertical direction and immovable in the horizontal direction. In addition, since the guide hole 43 is non-circular, the operation button 44 is inserted into the guide hole 43 so as not to rotate, thereby preventing the operation button 44 from rotating in the horizontal plane, and maintaining the posture of the operation button 44 constant. Has been.

The operation button 44 is movable in the vertical direction (inside / outside direction) between the push-in position shown in FIGS. 1, 2, and 14 and the initial position shown in FIGS. The pushing position of the operation button 44 is determined by the head 44 a formed at the upper end of the operation button 44 hitting the upper surface of the unit main body 41. On the other hand, the initial position of the operation button 44 is determined by a locking mechanism 45 provided between the unit main body 41 and the operation button 43.

That is, as shown in FIG. 10, the operation button 44 has a substantially rectangular parallelepiped box shape, and one side portion and the other side portion in the horizontal direction are opened. As shown in FIGS. 1 to 3, 14, and 15, a locking piece 45 a is formed at the center of the bottom surface of the operation button 44. This locking piece 45a is inclined so as to go from the inside to the outside of the operation button 44 as it goes upward, and its upper end is an operation button in a natural state where no external force acts on the locking piece 45a. It protrudes outside through the open part of 44. However, since the operation button 44 is inserted into the guide hole 43, the upper end portion of the locking piece 45a is pressed against the inner peripheral surface of the guide hole 43 by the elasticity of the locking piece 45a itself. Therefore, the upper end portion of the locking piece 45a slides in the vertical direction on the inner peripheral surface of the guide hole 43 as the operation button 44 moves in the vertical direction. A locking recess 45b is formed in a portion of the inner peripheral surface of the guide hole 43 where the upper end of the locking piece 44a slides. As shown in FIGS. 3 and 15, when the upper end portion of the locking piece 45a hits the upper end surface of the locking recess 45b, the operation button 44 cannot move upward. The position of the operation button 44 at this time is the initial position.

An engaging recess 45 c is formed on the inner peripheral surface of the guide hole 43. The engaging recess 45c is disposed immediately below the engaging recess 45b. When the operation button 44 moves downward from the initial position and reaches the pushing position, the upper end portion of the locking piece 45a enters the engaging recess 45c. Then, due to the inclined bottom surface of the engaging recess 45c and the elasticity of the locking piece 45a itself, the upper end of the locking piece 45a is urged downward, and the head 44a of the operation button 44 is pressed against the upper surface of the unit body 41. It is done. As a result, the operation button 44 is held at the pushing position without play.

At the lower end portion of the unit main body 41, an intermediate portion of a release lever (detaching member) 46 is provided so as to be rotatable (swingable) in the vertical direction via horizontal shafts 47, 47. One end portion of the release lever 46 is located facing the lower end portion of the guide hole 42, and the other end portion enters the inside of the cylindrical portion 42.

The release lever 46 is urged to rotate clockwise in FIGS. 14 and 15 by a coil spring 48. One end of the release lever 46 is pressed against the lower end surface of the operation button 44 by this rotational biasing force. Therefore, the release lever 46 is rotated following the movement of the operation button 44 in the vertical direction. In this case, the release lever 46 is rotated counterclockwise against the urging force of the coil spring 48 when the operation button 44 moves downward, and clockwise when the operation button 44 moves upward. Rotated to. 3 and FIG. 15, the release lever 46 is in the mounting position when the operation button 44 is in the initial position, and the operation button 44 is in the position as shown in FIG. 1, FIG. 2, and FIG. When in the push-in position, it is in the removal position.

Here, it is assumed that the socket S is not connected to the plug portion 22 and is in a disconnected state. In the non-connected state, as shown in FIGS. 1 and 2, the operation button 44 is located at the push-in position, and the release lever 46 is located at the removal position. When the socket S is extrapolated to the plug portion 22, the socket S pushes the other end of the release lever 46 downward, rotates the release lever 46 clockwise from the removal position, and moves the operation button 44 upward from the push-in position. Let As shown in FIG. 3, when the socket S is extrapolated to the plug portion 22 to a predetermined connection position, the socket S is connected to the plug portion 22. Further, by the extrapolation to the connection position of the socket S, the release lever 46 is rotated from the removal position to the attachment position, and the operation button 44 is moved from the push-in position to the initial position.

Conversely, when the operation button 44 is moved from the initial position to the removal position while the socket S is connected to the plug portion 22, the release lever 46 rotates from the attachment position to the removal position and pushes the socket S upward. Then, the connection state of the socket S to the plug portion 22 is released, and the socket S is removed from the plug portion 22. In addition, since the connection structure to the plug part 22 of the socket S is known, the detailed description is abbreviate | omitted. Further, the structure for removing the socket S from the plug portion 22 is not limited to the above structure, and other known structures may be adopted.

As shown in FIGS. 1 to 3, the sub operation button 5 is placed on the upper surface of the head 44 a of the operation button 44. The sub operation button 5 moves up and down together with the operation button 44. Therefore, the position of the sub operation button 5 when the operation button 44 is in the initial position is also referred to as the initial position, and the position of the sub operation button 5 when the operation button 44 is in the removal position is also referred to as the removal position.

In particular, as shown in FIGS. 16 to 19, a positioning recess 51 is formed on the lower surface of the sub operation button 5. The positioning recess 51 has the same plan view shape as the head 44a. That is, the positioning recess 51 has a substantially rectangular shape in plan view. A head 44a is inserted into the positioning recess 51 so as to be detachable in the vertical direction and immovable in the horizontal direction. Of course, the head 44a is inserted into the positioning recess 51 so as not to rotate. By inserting the head portion 44a into the positioning recess 51, the sub operation button 5 is positioned in the horizontal direction with respect to the operation button 44, and the rotational posture is determined in the horizontal plane. The positioning recess 51 does not necessarily have the same planar view shape as that of the head 44a. The head 44a can be attached to and removed from the positioning recess 51 in the vertical direction, cannot move in the horizontal direction, and cannot rotate. As long as it is inserted, you may make it the planar view shape different from the head 44a. The depth of the positioning recess 51 is shallower than the thickness (vertical dimension) of the head 44a in the vertical direction. Therefore, when the head portion 44a is inserted into the positioning recess 51, only the bottom surface of the positioning recess 51 contacts the upper surface of the head portion 44a, and the other portions of the sub operation button 5 contact the upper surfaces of the unit main body 41 and the head portion 44a. Never do.

A protrusion 52 is formed on the upper surface of the sub operation button 5. The protrusion 52 has the same planar view shape as the head 44a. Moreover, the protrusion 52 is disposed at the same position in the horizontal direction as the head 44a. Accordingly, by inserting the protrusion 52 of the sub operation button 5 into another sub operation button, for example, the positioning recess 51 of the other sub operation button 5, the other sub operation button 5 is superimposed on the sub operation button 5. Can do. The protrusion 52 may be formed in a different planar view shape from the head 44a as long as it can be inserted into and removed from the positioning recesses of the other sub-operation buttons and cannot move in the horizontal direction. You may arrange | position in a different position in the horizontal direction with the head 44a.

As shown in FIGS. 1 to 3, the mounting plate 6 is placed on the upper surface of the floor plate F. As shown in FIG. 9, the mounting plate 6 is made of a thin metal plate and is formed in a substantially rectangular frame shape. The mounting plate 6 is disposed so as to cover the through hole Fa. Moreover, the mounting plate 6 is arranged so that the plug portion 22 and the sub operation button 5 are positioned inside the mounting plate 6 in plan view. The mounting plate 6 is pressed and fixed to the upper surface of the floor plate F by tightening screws B2 and B2 that pass through the mounting plate 6 and are screwed into the cover 3.

A decorative plate 7 is detachably attached to the mounting plate 6. The decorative plate 7 has a frame shape that is substantially square in plan view, and has a size and shape that can cover the mounting plate 6 so that it cannot be seen from the room. A window hole 71 is formed in the center of the decorative plate 7. The window hole 71 not only has the plug portion 22 and the sub-operation button 5 positioned inside the window hole 71 when viewed in plan, but also allows the socket S to be connected to the plug portion 22 through the inside thereof. The shape and size of the sub-operation button 5 and the position in the horizontal direction are determined so that the sub-operation button 5 can be pushed down from the initial position to the removal position.

As shown in FIG. 5, the vertical width of the window hole 71 in FIG. 5 is smaller than the dimension of the sub operation button 5 in the same direction. Therefore, in a state in which the decorative plate 7 is attached to the attachment plate 6, the sub operation button 5 cannot be removed to the upper side in FIG. The dimension in the vertical direction in FIG. 6 inside the mounting plate 6 is set to a dimension that allows the sub operation button 5 to pass through in the vertical direction. Therefore, by removing the decorative plate 7, the sub operation button 5 can be removed to the room I side, and another sub operation button can be placed on the head 44a from the room I side through the mounting plate 6. .

A lid 72 is attached to the window hole 71. The lid 72 can be displaced between a closed position shown in FIG. 1 and an open position shown in FIG. The lid 72 closes the entire window hole 71 when it is in the closed position. On the other hand, when the lid 72 is located at the open position, the lid 72 moves to one end of the window hole 71 (left end in FIG. 2) and rises up and down, and the lid 72 itself exists. The window hole 71 is opened except for the portion.

A guide portion 73 extending downward from the lower surface of the decorative plate 7 is formed. The guide portion 73 has a substantially cylindrical shape, and both upper and lower end portions are open. The sub-operation button 5 is inserted into the guide portion 73 so as to be movable in the vertical direction, not movable in the horizontal direction, and not rotatable. As a result, the sub-operation button 5 can move up and down without play. Of course, since the guide part 73 is open | released upwards, a finger | toe can be inserted in the guide part 73 from the window hole 71, and the suboperation button 5 can be pushed down.

An example of a method for installing the underfloor buried gas plug 1 having the above-described configuration will be described in accordance with a construction procedure for a house. Installation of the gas plug 1 is performed after a joist of a house is provided and a primary side gas pipe having iron or other rigidity is provided in a space below the house. When the gas stopper 1 is installed, a tapered male thread portion is formed in advance on the outer peripheral surface of the distal end portion (downstream end portion) of the primary side gas pipe. A cover 3 is attached to the gas plug body 2 in advance.

After the preparation as described above, first, the taper male thread portion of the primary side gas pipe is screwed and fixed to the gas passage 23 opened to the gas pipe connection portion 21 of the gas plug body 2. Thereby, the gas stopper main body 2 is supported by the primary side gas pipe. Thereafter, the cover 3 is fixed to the joists. The cover 3 may be fixed to the joist before the gas stopper main body 2 is screwed to the gas pipe. The work so far is performed before the floor board F is placed and fixed on the joists.

After the floor board F is placed on the joists, a through hole Fa is formed in the floor board F as shown in FIG. Next, the screw B <b> 2 is inserted into the mounting plate 6 and screwed into the cover 3. Then, the mounting plate 6 is pressed and fixed to the upper surface of the floor plate F by tightening the screw B2. Thereafter, the sub operation button 5 is placed on the head 44 a of the operation button 44. The sub operation button 5 may be placed on the head 44a before the mounting plate 6 is fixed to the floor plate F. In FIG. 21, the sub operation button 5 is omitted. Next, the decorative plate 7 is attached to the attachment plate 6. Thereby, installation of the gas stopper 1 is completed.

When connecting the socket S to the plug portion 22 of the gas plug 1, the lid 72 is first opened. Next, the socket S is inserted into the cylinder part 42 from the room I side through the window hole 71 and is externally inserted into the plug part 22. When the socket S is extrapolated to the plug portion 22 to a predetermined connection position, the socket S is connected to the plug portion 22 so that it cannot be removed indoors. At this time, along with the extrapolation of the socket S to the plug portion 22, the sub operation button 5 is moved upward from the pushing position to the initial position together with the operation button 44, and the release lever 46 is rotated from the removal position to the attachment position. ing.

When removing the socket S from the plug part 22, a finger is inserted into the guide part 73 from the window hole 71, and the sub operation button 5 and the operation button 44 are pushed downward. When the sub-operation button 5 and the operation button 44 are pushed from the initial position to the push-in position, the release lever 46 is rotated from the attachment position to the removal position, whereby the socket S is removed from the plug portion 22. Thereafter, the socket S is pulled out from the window hole 71 to the indoor side. Then, the lid 72 is returned to the closed position.

In the underfloor buried gas plug 1 having the above-described configuration, the sub operation button 5 is merely placed on the operation button 44, and therefore a position adjusting bolt for adjusting the vertical position of the sub operation button 5 is used. Is unnecessary. Therefore, the number of parts of the gas stopper 1 can be reduced by that amount, and the manufacturing cost of the gas stopper 1 can be reduced. In addition, the sub operation button 5 is simply placed on the operation button 44, and there is no need to rotate the position adjusting bolt relative to the sub operation button 5. Therefore, the installation cost of the gas stopper 1 can be reduced.

In addition, the gas stopper main body 2 has a height (vertical thickness) different from that of the sub-operation button 5 corresponding to the vertical mounting position (distance from the upper surface of the floor board F to the gas stopper main body 2). By using this sub-operation button, the upper surface of the sub-operation button can be positioned at a position suitable for operation with a finger within a range where it does not hit the decorative board 7.

For example, FIG. 22 shows an embodiment (second embodiment) in which the attachment position of the gas plug main body 2 is higher than the attachment position of the first embodiment. In the underfloor buried type gas stopper 1A of the second embodiment, a sub operation button 5A is employed instead of the sub operation button 5 of the above embodiment. The sub operation button 5A is configured in the same manner as the sub operation button 5 except that the height thereof is lower than the height of the sub operation button 5. Therefore, the sub operation button 5 </ b> A can be placed on the head 44 a of the operation button 44. Then, by using the sub-operation button 5A having a low height, the gas stopper main body 2 is absorbed on the upper side, and the upper surface of the sub-operation button 5A does not hit the decorative board 7 and is operated with a finger. It can be located at a position where it is easy to do. The gas stopper 1A is configured in the same manner as the gas stopper 1 of the above-described embodiment except that the auxiliary operation button 5A is used instead of the auxiliary operation button 5, and the same reference numerals are used for the same parts. The description is omitted. This also applies to the embodiments described below.

FIG. 23 shows an embodiment (third embodiment) when the attachment position of the gas plug main body 2 is lower than the attachment position of the above-described embodiment. In the underfloor buried gas plug 1B of the third embodiment, the sub operation button 5 used in the first embodiment and the sub operation button 5A used in the second embodiment are used at the same time. ing. That is, the bottom surface of the positioning recess 51 of the sub operation button 5 </ b> A is placed on the upper surface of the protrusion 52 of the sub operation button 5. Therefore, according to this gas plug 1B, the upper surface of the sub operation button 5A is pressed by the finger, and the position of the operation surface by the finger is set higher than that of the sub operation button 5 as compared with the first embodiment. It can be increased by that much. Therefore, even when the mounting position of the gas plug body 2 is low, the operability of the operation button 5A can be improved. The sub operation button 5A may be placed on the operation button 44, and the sub operation button 5 may be placed on the sub operation button 5A. Further, three or more sub operation buttons may be sequentially placed on the operation button 44.

  24 to 33 show a fourth embodiment of the present invention. In the underfloor buried type gas plug 1C of this embodiment, a sub operation button (sub operation member) 5B is used instead of the sub operation button 5, and a cap 8 is newly adopted.

  The sub-operation button 5B is formed with a plate portion 53 as shown in FIGS. 30 to 33 in particular. The plate portion 53 has a substantially triangular shape in plan view, and is disposed on a side surface of the sub operation button 5B facing the plug portion 22 side. A through hole 54 is formed in the plate portion 53 so as to penetrate the plate portion 53 in the vertical direction. Other configurations are the same as those of the sub operation button 5.

  26 to 29, the cap 8 is made of a hard rubber or other resin that is relatively hard but elastically deformable, and has a covering portion 81 and a connecting portion 82.

  The covering portion 81 is formed in a circular flat plate shape. As shown in FIG. 24, the outer diameter of the covering portion 81 is equal to or slightly larger than the outer diameter of the plug portion 22. A fitting protrusion 81a is formed on one surface of the covering portion 81 (the lower surface in FIGS. 27 to 29). The fitting protrusion 81 a has a circular cross section, and is arranged such that its axis coincides with the axis of the covering portion 81. The outer diameter of the fitting protrusion 81 a is slightly larger than the inner diameter of the plug portion 22. Accordingly, the fitting protrusion 81a can be press-fitted into the plug portion 22 from the tip opening. Then, the fitting projection 81 a is press-fitted into the inner periphery of the plug portion 22, so that the covering portion 81 is detachably attached to the plug portion 22 with a predetermined amount of force. Moreover, the covering portion 81 is attached to the plug portion 22 in a state where the axis line thereof coincides with the axis line of the plug portion 22. Therefore, when the covering portion 81 is attached to the plug portion 22, the distal end surface of the plug portion 22 is covered with the covering portion 81.

  An annular recess 81b is formed on one surface of the covering portion 81 where the fitting protrusion 81a is formed. The annular recess 81b is formed so as to surround the fitting protrusion 81a, and is arranged so that the inner peripheral portion is in contact with the fitting protrusion 81a. The annular recess 81b has the same cross-sectional shape as the end portion on the small diameter side of the tapered portion 22a and the planar portion 22b that continues to the inside of the end portion of the tip surface of the plug portion 22. Therefore, when the fitting protrusion 81a is inserted into the plug portion 22 until one surface of the covering portion 81 contacts the plug portion 22, the bottom surface of the annular recess 81b is tightly connected to the end portion on the small diameter side of the tapered portion 22a and the flat portion 22b. Contact. This prevents dust and the like from adhering to the end portion on the small diameter side of the tapered portion 22a and the flat portion 22b. Here, the end portion on the small diameter side of the taper portion 22a and the flat portion 22b are portions that contact the socket S via a seal member such as packing when the socket S is connected to the plug portion 22. Therefore, when the gas plug 1C is not used, the covering portion 81 is attached to the plug portion 22 to prevent dust and the like from interposing between the contact surfaces when the socket S is connected to the plug portion 22. can do. Therefore, the plug part 22 and the socket S can be connected in an airtight manner.

  On the other surface (upper surface in FIGS. 27 to 29) of the covering portion 81, a grip protrusion portion 81 c is formed. The gripping protrusion 81c is used when the covering part 81 is removed from the plug 22. The gripping protrusion 81c is gripped by inserting a finger through the window hole 71 and lifting the gripping protrusion 81c upward. The part 81 is removed from the plug part 22. Here, the distance for inserting the finger from the window hole 71 can be shortened by the amount of protrusion of the gripping protrusion 81c, and the covering portion 81 can be easily detached from the plug portion 22 by that amount. Therefore, it is convenient to form the gripping protrusion 81c when the distance from the upper surface of the decorative plate 7 to the plug portion 22 is long. On the contrary, when the distance from the upper surface of the decorative board 7 to the plug part 22 is short, the grip protrusion part 81c does not necessarily need to be formed. When the grip protrusion 81 c is not formed, the cover 81 can be removed from the plug 22 by gripping the outer peripheral surface of the cover 81 with a finger and lifting it upward.

  A base end portion of the connecting portion 82 is formed integrally with the covering portion 81 on one side portion of the outer peripheral surface of the covering portion 81. The connecting portion 82 may be formed separately from the covering portion 81, and one end portion (base end portion) thereof may be fixed by adhesion or other means. The distal end portion of the connecting portion 82 extends in the radial direction of the covering portion 81 so as to be separated from the covering portion 81. The connecting portion 82 may not necessarily extend in the radial direction of the covering portion 81 but may extend in a direction inclined with respect to the radial direction. Since the connecting portion 82 is made of an elastic resin as described above and is formed to be elongated, it can be elastically deformed. The connecting portion 82 need not be elastically deformable as long as it can be deformed. For example, the connecting portion 82 may be formed of a string-like body that can be deformed and that maintains the deformed state.

  A pair of retaining protrusions 82 a are formed at the distal end of the connecting portion 82. The pair of retaining protrusions 82 a are disposed 180 degrees apart in the circumferential direction of the connecting portion 82. The retaining protrusion 82 a is inclined so as to be separated from the connecting portion 82 as it goes from the distal end of the connecting portion 82 to the proximal end side. Therefore, the distance between the pair of retaining protrusions 82a and 82a increases from the distal end of the connecting portion 82 toward the proximal end, and is largest at the distal end of the retaining protrusion 82a. The distance between the outer ends of the pair of retaining protrusions 82a, 82a at the distal end portion (the end portion on the proximal end side of the connecting portion 82) is larger than the inner diameter of the through hole 54 of the sub operation button 5B. However, the pair of retaining protrusions 82a and 82a can pass through the through hole 54 by elastically deforming their tip portions so as to approach each other, and after passing through the through hole 54 as shown in FIG. Elastically returns and deforms. As a result, the connecting portion 82 is inserted into the through hole 54 in a retaining state, and the cap 8 is attached to the sub operation button 5 </ b> B via the connecting portion 82.

  The cap 8 may be attached to the sub operation button 5A when the sub operation button 5A is used instead of the sub operation button 5B or together with the sub operation button 5B. Alternatively, the cap 8 may be attached to the operation button 5.

  When the gas plug 1 </ b> C having the above-described configuration is not used, the window hole 71 is closed by the lid 72, and the distal end portion of the plug portion 22 is covered by the covering portion 81. When the gas stopper 1C is used, the lid 72 is first rotationally displaced to open the window hole 71. Next, the covering portion 81 is removed from the plug portion 22. Here, since the connecting portion 82 is attached to the sub operation button 5B in a retaining state, it is possible to prevent a situation in which the cap 8 is lost after the covering portion 81 is removed from the plug portion 22. Thereafter, the socket S is connected to the plug portion 22. At this time, dust or the like does not intervene at the tip end portion of the plug portion 22 that contacts the socket S, that is, the end portion on the small diameter side of the taper portion 22a and the flat portion 22b. Can be connected. The cover 81 removed from the plug portion 22 is sandwiched between the sub operation button 5B and the guide portion 73 as shown in FIG. 25 so as not to interfere with the connection of the socket S to the plug portion 22. . When the use of the gas plug 1C is finished, the socket S is removed from the plug portion 22. Next, the covering portion 81 is attached to the plug portion 22. Thereafter, the window hole 71 is closed by the lid 72.

  34 and 35 show a unit main body (supporting member) 41A used in place of the unit main body 41. FIG. The unit main body 41A is formed with a through hole 41a penetrating vertically through the unit main body 41A. The through hole 41 a is disposed in the vicinity of the guide hole 43. Other configurations of the unit main body 41A are the same as those of the unit main body 41.

  A cap 8 is attached to the unit main body 41A. That is, the tip end portion of the coupling portion 82 of the cap 8 is inserted into the through hole 41a in a state of being prevented from being detached by the pair of protrusions 82a and 82a. Thereby, the cap 8 is attached to the unit main body 41A.
