FIG. 11 is a cross-sectional view showing the same embodiment attached to a floor board in a third mode different from the mode shown in FIG. 1.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 shows a floor board F provided with a buried gas plug 1 according to an embodiment of the present invention. The floor board F is formed with a through hole Fa having a circular cross section that penetrates the floor board F up and down. Most of the gas stopper 1 is inserted into the through hole Fa. The floor board F is disposed above the ground or the floor slab S by a predetermined distance.

  As shown in FIGS. 1 to 5, the gas stopper 1 has a casing 2. The casing 2 is formed in a substantially bottomed cylindrical container shape, and is arranged with its opening directed toward the room I, that is, in a state directed upward. The casing 2 may have a non-circular cross-sectional shape such as a square cross section. The outer diameter of the casing 2 is set smaller than the through hole Fa. The casing 2 is inserted into the through hole Fa in a state in which the axis thereof coincides with the axis of the through hole Fa. The axis of the casing 2 does not necessarily need to coincide with the axis of the through hole Fa, and may be arranged parallel to the axis of the through hole Fa while being spaced apart in the horizontal direction.

The casing 2 is fixed to the floor plate F by a mounting plate 5 described later. In the fixed state, the lower end surface of the casing 2 is positioned substantially on the same plane as the lower end surface of the floor board F. The lower end surface of the casing 2 does not necessarily need to be positioned on the same plane as the lower end surface of the floor board F. The relationship between the lower end surface of the casing 2 and the lower end surface of the floor board F varies depending on the thickness of the floor board F. That is, when the floor plate F is relatively thin, the lower end surface of the casing 2 is positioned below the lower end surface of the floor plate F , and when the floor plate F is relatively thick, The end surface is located above the lower end surface of the floor board F.

  A flat portion 21 is formed on the outer peripheral surface of the casing 2. By screwing and tightening a wood screw (not shown) inserted through the flat portion 21 into a joist (not shown; a constituent member of the floor including the floor plate) that supports the floor board F, the flat section 21 can be either left or right of the joist. It is possible to fix the casing 2 to the joist by pressing against the side surface. When the casing 2 is fixed to the joist, it is not necessary to fix the casing 2 to the floor plate F with the mounting plate 5 described later.

  A gas stopper main body 3 is accommodated in the casing 2. The gas plug body 3 is fixed to the bottom of the casing 2 with screws B1. The gas plug main body 3 has a gas pipe connection part 31 and a plug part 32, and a part excluding the gas pipe connection part 31 and the plug part 32 is a main part. As shown in FIG. 3, a gas passage 33 is formed inside the gas plug body 3. The upstream end portion of the gas passage 33 is open to the upstream end surface (the lower end surface in FIG. 3) of the gas pipe connection portion 31. The downstream end portion of the gas passage 33 is open to the downstream end surface (upper end surface in FIG. 3) of the plug portion 32.

  The gas pipe connection portion 31 has a tubular shape by forming a gas passage 33 therein. An upstream end portion of the gas pipe connection portion 31 protrudes outside the casing 2 through a notch portion 22 formed in the casing 2. A tapered female thread portion 31 a is formed on the inner peripheral surface of the upstream end portion (the lower end portion in FIGS. 2 and 3) of the gas pipe connection portion 31. As shown in FIG. 1, a joint C is screwed and fixed to the taper female thread portion 31a. A primary side gas pipe G made of a flexible gas pipe is connected to the joint C. Therefore, the gas is supplied from the primary side gas pipe G through the joint C to the inside of the gas pipe connection portion 31, that is, the upstream end portion of the gas passage 33.

  The plug part 32 has a shape and a dimension determined by a Japanese Industrial Standard quick joint (JIS S 2120), and is arranged with its axis line directed vertically. That is, the plug part 32 is disposed in parallel with the through hole Fa. As shown in FIG. 3, the plug portion 32 is disposed closer to the room I than the base end portion 31 b of the gas pipe connection portion 31. As a result, a rectangular space is defined on the upper side of the base end portion 31 b of the gas pipe connection portion 31 by the base end portion 31 b and the plug portion 32.

A socket (not shown) is detachably connected to the plug portion 32. The socket is connected to a gas device (both not shown) through a secondary gas pipe. Therefore, when the socket is connected to the plug portion 32, the gas flowing into the gas passage 33 from the primary side gas pipe is supplied to the gas equipment through the socket and the secondary side gas pipe.

  Inside the gas passage 33, a main valve 34 and a sub valve 35 are provided. When the socket is connected to the plug portion 32, the main valve 34 and the sub valve 35 move from the closed position shown in FIG. 3 to the open position to automatically open the gas passage 33. On the other hand, when the socket is removed from the plug portion 32, the gas passage 33 is automatically closed by moving from the open position to the closed position. An excessive outflow prevention valve mechanism 36 is provided inside the gas passage 33. The overflow prevention valve mechanism 36 is disposed upstream of the main valve 34 and automatically closes the gas passage 33 when the flow rate of the gas flowing in the gas passage 33 exceeds a predetermined flow rate. The overflow prevention valve mechanism 36 is automatically reset when the main valve 34 moves from the open position to the closed position, and opens the gas passage 33. The main valve 34, the sub valve 35, and the excessive outflow prevention valve mechanism 36 are well known and have a low relevance to the present invention. Therefore, the detailed description thereof is omitted.

  As shown in FIGS. 3 to 5, the gas stopper main body 3 is provided with a removal unit (removal mechanism) 4. The removal unit 4 is for removing the socket connected to the plug portion 32 from the plug portion 32, and has a unit main body 41. The unit main body 41 is fixed to the gas plug main body 3 with screws B2.

  A cylindrical portion 41 a is formed at one end portion of the unit body 41 in the horizontal direction (left end portion in FIG. 6). The cylinder part 41 a has a circular cross section, and is arranged with its axis line coincident with the axis line of the plug part 32. Moreover, the cylindrical portion 41a is set to have a larger diameter than the plug portion 32, and the plug portion 32 is inserted therein. Therefore, when connecting the socket to the plug portion 32, the socket is inserted between the inner peripheral surface of the tube portion 41 a and the outer peripheral surface of the plug portion 32.

The other end portion of the unit body 41 in the horizontal direction (the left end portion in FIG. 3 and the right end portion in FIG. 6) is disposed in a space defined by the base end portion 31b and the plug portion 32. A guide hole 41b is formed in the part. The guide hole 41b penetrates the unit body 41 in the vertical direction. A push button 42 is inserted into the guide hole 41b so as to be movable in the vertical direction.

  An intermediate portion of the swing member 43 is provided at the intermediate portion in the horizontal direction of the unit main body 41 so as to be swingable in the vertical direction around the horizontal axis. One end portion (right end portion in FIG. 6) of the swing member 43 is pressed against the lower end surface of the push button 42 by the spring 44. The other end portion of the swing member 43 is disposed so as to face the outer peripheral surface of the plug portion 32. When a socket is connected to the plug portion 32, the other end of the swing member 43 is pushed downward by the socket, and one end of the swing member 43 moves the push button 42 upward. When the push button 42 is pressed downward in a state where the socket is connected to the plug portion 32, one end of the swing member 43 moves downward and the other end moves upward. Then, the socket is detached from the plug portion 32. In addition, since such a removal structure is well known, further description is abbreviate | omitted.

  As shown in FIGS. 4 and 8, the mounting plate 5 is fixed to the upper surface of the floor plate F with a wood screw T <b> 1. The mounting plate 5 has a substantially rectangular frame shape, and is disposed so as to cover the through hole Fa and the surrounding floor plate. As shown in FIGS. 1, 4, and 7, a screw B <b> 3 is inserted through the mounting plate 5. The screw 2 is screwed into the casing 2 and tightened, whereby the casing 2 is fixed to the mounting plate 5 and eventually to the floor plate F. As is clear from this, the fixing means is constituted by the mounting plate 5, the wood screw T <b> 1 that fixes the same to the floor plate F, and the screw B <b> 3 that fixes the casing 2 to the mounting plate 5. Various fixing means are known, and these known fixing means may be used.

A decorative plate 6 is detachably attached to the mounting plate 5. The decorative plate 6 covers the mounting plate 5 so that the mounting plate 5 is not viewed from above. A window hole 61 is formed in the decorative plate 6. An opening / closing lid (lid body) 62 is provided in the window hole 61 so as to be movable between a closed position shown in FIG. 1 and an open position shown in FIG. When the opening / closing lid 62 is moved to the closed position, the opening / closing lid 62 is fitted into the window hole 61. As a result, the window hole 61 is closed by the opening / closing lid 62. When the open / close lid 62 is moved to the open position, as shown in FIG. Moreover, it almost contacts one end of the window hole 61. As a result, the open / close lid 62 is positioned along the inner peripheral surface of the peripheral wall portion of the casing 2. Moreover, it is located in front of the base end portion 31 b of the gas pipe connection portion 31. When the opening / closing lid 62 is in the open position, the window hole 61 is opened. When the window hole 61 is opened, the socket can be inserted into the casing 2 through the window hole 61 and connected to the plug portion 32. Further, the socket can be removed from the plug portion 32 by inserting a finger through the window hole 61 and pushing the push button 42 downward.

  The gas pipe connection part 31 is formed separately from the main part of the gas plug main body 3, and both have an upstream part 31A and a downstream part 31B made of a pipe.

  The tapered female screw hole 31a is formed in the upstream opening (the lower opening in FIG. 3) of the upstream portion 31A. As described above, the pipe joint C is screwed and fixed to the tapered female screw hole 31a, and the primary side gas pipe G is connected to the pipe joint C. The upstream end portion (lower end portion in FIG. 3) of the downstream portion 31B is fixed to the downstream end portion (upper end portion in FIG. 3) of the upstream portion 31A by screws B4. Thereby, the whole gas pipe connection part 31 is integrated and formed in the tubular shape as a whole.

  The downstream portion 31B is bent at a substantially right angle at its intermediate portion. As a result, the downstream portion 31B is divided into a downstream side (upper side in FIG. 3) base end portion 31b and an upstream side portion (lower side portion in FIG. 3). As described above, the upstream portion 31A is fixed to the upstream portion. As a result, the upstream end portion 31c of the gas pipe connecting portion 31 is configured by the upstream portion and the upstream portion 31A of the downstream portion 31B.

On the other hand, the base end portion 31b of the downstream portion 31B is arranged with its axis line oriented in the horizontal direction. In particular, in this embodiment, the axis of the base end portion 31 b is orthogonal to the axis of the plug portion 32. A protrusion 37 formed on the gas plug body 3 is inserted into the base end portion 31b so as to be rotatable about the axis of the base end portion 31b. Accordingly, the downstream portion 31B, and thus the gas pipe connection portion 31, is coupled to the gas plug main body 3 so as to be rotatable about a horizontal axis (axis of the base end portion 31b). The gas pipe connecting portion 31 can rotate between at least a vertical position shown in FIG. 2 where the upstream portion 31A faces downward and a horizontal position (see FIG. 11) where the upstream portion 31A faces leftward in FIG. is there.

Here, the notch portion 22 of the casing 2 has a size that allows the gas pipe connection portion 31 to rotate between the vertical position and the horizontal position. Therefore, the rotation of the gas pipe connecting portion 31 is not hindered by the casing 2 . Further, the rotation region of the distal end portion 31c of the gas pipe connection portion 31, that is, the region that passes through when the distal end portion 31c rotates, is the opening / closing lid 62 that is located at the open position with the proximal end portion 31b of the gas pipe connection portion 31 It is arranged between. Therefore, when the distal end portion 31 c of the gas pipe connecting portion 31 rotates around the proximal end portion 31 b, the distal end portion 31 c does not hit the opening / closing lid 62 .

  The gas stopper 1 can be attached to the floor board F as follows, for example. First, as shown in FIG. 7, a through hole Fa is formed in the floor board F. At this time, the primary side gas pipe G is connected to the lower side of the floor board F in a state where the primary side gas pipe G is connected. Alternatively, after the formation of the through hole Fa, the primary side gas pipe G is drawn into the room I from the through hole Fa, and the gas pipe G is connected to the gas pipe connection portion 31 via the joint C. Then, you may insert the gas pipe G and the gas stopper 1 in the through-hole Fa.

Next, the screw B 3 is inserted into the mounting plate 5 and screwed into the casing 2. Then, the casing 2 is fixed to the mounting plate 5 by tightening the screw B3. After that, as shown in FIG. 8, the mounting plate 5 is pressed and fixed to the upper surface of the floor plate F by the wood screw T1. As a result, the casing 2 is fixed to the floor plate F via the mounting plate 5. Thereafter, the decorative plate 6 is attached to the mounting plate 5 to complete the mounting of the gas plug 1 to the floor plate F.

  In the buried type gas plug 1 having the above-described configuration, the gas pipe connecting portion 31 is bent at a right angle in the middle portion thereof, and the base end portion 31b can be rotated around the horizontal axis, so that the gas pipe connecting portion 31 The direction of the tip 31c can be changed. For example, as shown in FIG. 1, when the space | interval of the floor board F and the floor slab S is wide, the gas pipe connection part 31 can be rotated to a vertical position, and the front-end | tip part 31c can be faced below. When the front end portion 31 c of the gas pipe connection portion 31 is directed downward, the primary gas pipe G connected to the gas pipe connection portion 31 can be disposed along the floor slab S.

FIG. 10 shows an embodiment in which the distance between the floor board F and the floor slab S is narrower than that in the embodiment shown in FIG. 1, and the gas pipe connecting portion 31 is located between the vertical position and the horizontal position. It is located in the inclination position which is an intermediate position. That is, the distal end portion 31c of the gas pipe connecting portion 31 is inclined by approximately 45 ° with respect to the vertical direction and the horizontal direction. When the distal end portion 31c of the gas pipe connecting portion 31 is inclined, the length in the vertical direction of the gas pipe connecting portion 31 and the joint C screwed to the gas pipe connecting portion 31 is shortened by the inclination angle. It is possible to cope with a case where the distance between the slab and the floor slab S is narrow. The embodiment shown in FIG. 10 has the same configuration as the embodiment shown in FIGS. 1 to 9 except that the distance between the floor board F and the floor slab S is different.

  FIG. 11 shows an embodiment in which the thickness of the floor board F is thinner than the floor board F of the embodiment shown in FIG. 1, and the gas pipe connecting portion 31 is positioned in the horizontal position, and its tip portion 31c. Is oriented horizontally. Therefore, the gas pipe G does not need to be bent in the vicinity of the joint C as in the embodiment shown in FIGS. 1 to 9 or 10, and is connected to the gas pipe connecting portion 31 in a state of extending straight in the horizontal direction. The gas pipe G, the joint C, and the gas pipe connection portion 31 can be arranged in one horizontal plane. Therefore, it is possible to cope with a case where the distance between the floor board F and the floor slab S is narrow. The embodiment shown in FIG. 11 has the same configuration as that of the embodiment shown in FIGS. 1 to 9 except that the thickness of the floor board F is different and the distance between the floor board F and the floor slab S is different. have. Further, in this embodiment, the entire gas plug 1 is not accommodated in the through hole Fa, and only a part on the indoor I side is accommodated in the through hole Fa. As is clear from this, in the present invention, “the gas stopper is provided in the through hole” includes both the case where the entire gas stopper is accommodated in the through hole and the case where only a part is accommodated. It is a waste.

  Thus, according to the buried type gas plug 1, since the gas pipe connecting portion 31 is rotatable with respect to the gas plug main body 3, various usage modes in which the distance between the floor board F and the floor slab S is different, and Various types of use with different thicknesses of the floorboard F can be handled with only one gas plug 1, and various types of buried gas plugs with different orientations of the gas pipe connection portion are used depending on the mode of use. There is no need. Therefore, the manufacturing cost and management cost of the buried gas plug 1 can be reduced.

  Moreover, since the notch part 22 which permits rotation of the front-end | tip part 31c of the gas pipe connection part 31 is formed in the casing 2, the rotation angle of the gas pipe connection part 31 is enlarged without enlarging the casing 2. be able to. This is because the rotation region of the distal end portion 31c of the gas pipe connecting portion 31 is disposed between the opening / closing lid 62 and the proximal end portion 31b which are located at the open position. That is, if the opening / closing lid 62 located at the open position is set at a position 90 ° apart in the circumferential direction of the casing 2 with respect to the above embodiment, when the tip 31c is rotated so as to be horizontal, Since the distal end portion 31c hits the opening / closing lid 62, the rotation angle of the gas pipe connecting portion 31 must be reduced. In this regard, as in the above-described embodiment, when the rotation region of the distal end portion 31c of the gas pipe connection portion 31 is disposed between the opening / closing lid 62 and the proximal end portion 31b positioned at the open position, the distal end portion 31 c does not hit the opening / closing lid 62. Therefore, the rotation angle of the gas pipe connection part 31 can be increased.

  Furthermore, since the base end portion 31b of the gas pipe connecting portion 31 is arranged below the push button 42 (outdoor O side), in other words, in the space defined by the base end portion 31b and the plug portion 32. Since the push button 42 is arranged, it is possible to eliminate the existence of a useless space in the gas plug 1, and as a result, the gas plug 1 can be reduced in size.

In addition, this invention is not limited to the said embodiment, A various modification is employable in the range which does not deviate from the summary.
For example, in the above-described embodiment, the gas plug 1 is disposed in Fa that penetrates the floor plate F up and down, but the gas plug 1 can also be provided on a wall plate such as an inner wall. In that case, a through-hole penetrating in the horizontal direction is formed in the wall plate, and the gas stopper 1 is disposed in the through-hole. Of course, the gas plug 1 is disposed in the through hole in a state where the axis of the plug portion 32 coincides with or is parallel to the axis of the through hole. The gas plug 1 is directly fixed to the wall plate or is fixed to a constituent member of the wall including a wall plate such as a pier that supports the wall plate.

  The buried type gas stopper according to the present invention can be used for various usage modes in which the distance between the floor plate and the floor slab and the distance between the inner wall and the outer wall are different.
