Description

Technical Field

[0001] The present invention relates to an apparatus for attaching a gas plug to a plate-shaped interior material in which a through-hole is formed to separate the inside and outside of a room.

Background Art

[0002] The gas plug attachment device disclosed in Patent Document 1 below temporarily attaches a gas plug to a portion corresponding to the outside of a wall panel (interior material) before construction of the wall panel that separates the inside and outside of a room, and after construction of the wall panel, completes the attachment of the gas plug to the wall panel. It is a so-called gas plug pre-attached type.

[0003] The gas plug attachment device of Patent Document 1 includes a mounting plate (fixing frame), a device body (bracket), and a holder. The mounting plate is disposed on the indoor side surface of the wall panel and has a window hole facing the through-hole of the wall panel. The device body is fixed to a crossbar that supports the wall panel from the outdoor side. The holder faces the mounting plate on the outdoor side of the mounting plate, can have a gas plug attached thereto, and is supported by the device body so as to be movable in the indoor-outdoor direction.

[0004] In order to attach a gas plug to a wall panel using the gas plug attachment device of Patent Document 1, before constructing the wall panel, the device body is fixed to the crossbar. Next, the holder with the gas plug attached is supported by the device body, and two long bolts are inserted through two screw insertion holes of the holder and screwed into the device body to temporarily fix the holder and the device body.

[0005] Next, in order to protect the gas plug during wall panel construction and confirm the position of the through-hole formed in the wall panel, the gas plug is covered with a bottomed cylindrical position confirmation jig, and this jig is fixed to the holder with two middle bolts. After constructing the wall panel in which the through-hole is formed, the two middle bolts are removed to remove the jig, and the two long bolts that temporarily fix the holder and the device body are removed. Then, the mounting plate is disposed on the indoor side of the wall panel so as to face the through-hole.

[0006] Insert the two removed long bolts through the two screw insertion holes of the mounting plate, then through the two screw insertion holes of the holder, and thread them into the device body. Also, insert the two removed medium bolts through the other two screw insertion holes of the mounting plate and thread them into the holder. As a result, the mounting plate and the holder supported by the device body are fixed with the wall plate sandwiched therebetween, and the gas plug is installed with it built into the wall plate.

Summary of the Invention

Problems to be Solved by the Invention

[0008] In the gas plug mounting device of Patent Document 1, before the construction of the wall plate, the holder and the device body were temporarily fixed with two long bolts, and a position confirmation jig was fixed to the holder with two medium bolts. After the construction of the wall plate, it was necessary to remove all the bolts and the jig, arrange the mounting plate, and then attach these bolts again. Therefore, it was time-consuming to install the gas plug, and the installation of the gas plug was not easy.

[0009] Also, there is a demand for a gas plug mounting device that can mount a gas plug on a wall plate after the construction of the wall plate without temporarily mounting the gas plug before the construction of the wall plate, that is, a so-called gas plug retrofit type. In the gas plug mounting device of Patent Document 1, the holder with the gas plug attached has guide plate portions on both sides thereof for supporting it on the device body.

[0010] In the gas plug mounting device of Patent Document 1, if, after the construction of the wall plate, an attempt is made to insert the holder with the gas plug through the through-hole from the room and support it on the device body, it is necessary to enlarge the through-hole by the amount of the guide plate portion. This is contrary to the object of the invention of the gas plug mounting device of Patent Document 1, which is to reduce the size of the through-hole. Therefore, it was difficult to make the gas plug mounting device of Patent Document 1 a gas plug retrofit type.

Means for Solving the Problems

[0011] The present invention has been made to solve at least one of the above problems, and a gas plug mounting device according to one aspect of the present invention is a device for mounting a gas plug on a plate-shaped interior material in which a through-hole is formed to separate the inside and outside of a room, and a fixing frame disposed on the indoor side surface of the interior material and having a window hole facing the through-hole, and a bracket having a frame plate portion in which a window hole is formed, which can be inserted into the through-hole from the indoor side, and the window hole is disposed on the outdoor side surface of the interior material so as to face the through-hole, and the bracket is connected to the fixing frame by a first connecting means, and a holder that faces the fixing frame on the outdoor side of the fixing frame, and a gas plug is attached with the plug portion facing the window hole of the fixing frame, and the holder is connected to the fixing frame by a second connecting means. In the gas plug mounting device, the holder to which the gas plug is attached and the fixing frame form a sub-assembly by the connection by the second connecting means, the fixing frame in the sub-assembly in which the holder is inserted into the through-hole from the indoor side is connected to the bracket by the first connecting means.

[0012] According to the above configuration, by making the holder with a gas plug and the fixing frame an integrated sub-assembly, the handling of these members is facilitated. The gas plug can be attached after the construction of the interior material. The bracket is passed through the through-hole from the indoor side and disposed on the outdoor side of the interior material, the sub-assembly is inserted into the through-hole from the indoor side, and the bracket and the sub-assembly are connected by the first connecting means. Thereby, the gas plug is attached in a state of being built in the interior material. That is, after the construction of the interior material, the gas plug can be easily attached into the interior material from the indoor side.

[0013] Preferably, the fixing frame is formed with a slit hole that is formed so as to be cut out from the outer peripheral edge, the bracket is provided with a fixing piece inside the frame plate portion, and the first connecting means is a screw that passes through the slit hole of the fixing frame and is screwed into the fixing piece of the bracket. When the screw is screwed into the fixing piece of the bracket disposed on the outdoor side of the interior material and the head projects into the room, the slit hole of the fixing frame in the sub-assembly with the holder facing the outdoor side can receive the shaft portion of the screw.

[0014] According to the above configuration, when the sub-assembly is inserted into the through-hole by receiving the shaft portion of the screw in the slit hole, the sub-assembly is guided by the shaft portion of the screw. Thereby, the ease of attaching the gas plug can be improved.

[0015] Preferably, the shaft portion of the screw received in the slit hole of the fixing frame in the sub-assembly is below the inner end of the slit hole. According to the above configuration, the sub-assembly guided by the shaft portion of the screw and inserted into the through-hole is supported by the shaft portion of the screw. Thereby, the ease of attaching the gas plug can be further improved.

[0016] Preferably, the protruding position of the head of the screw is set so as to avoid interference between the orbit of the sub-assembly and the interior material forming the peripheral edge of the through-hole when the sub-assembly with the shaft portion of the screw received in the slit hole is rotated to the outdoor side about the intersection of the slit hole and the shaft portion. According to the above configuration, the sub-assembly can be inserted into the through-hole while being rotated, which can contribute to improving the ease of attaching the gas plug and can reduce the space for attaching the gas plug.

Effect of the Invention

[0017] According to the present invention, a gas plug can be easily attached to an interior material that separates the indoor and outdoor spaces.

[0019] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 16. This embodiment applies the present invention to a gas plug mounting device for mounting a gas plug on a wall panel that separates the inside and outside of a room. In the following description, left and right mean left and right when viewed from the inside of the room to the outside.

[0020] As shown in FIG. 1, the gas plug mounting device 1 is a device for mounting a gas plug 3 in a state of being built in a wall panel 2 (interior material) in which a through hole 2a penetrating from the inside of the room to the outside is formed. As shown in FIGS. 1 and 2, the gas plug mounting device 1 can include, as components, a bracket 10, a holder 20, a spacer 30, and a fixing frame 40. The fixing frame 40 and the bracket 10 are respectively arranged on the indoor side and the outdoor side of the wall panel 2, and the holder 20 and the spacer 30 are arranged so as to face the fixing frame 40 on the outdoor side of the fixing frame 40. The bracket 10, the holder 20, and the fixing frame 40 are formed by pressing and punching a metal plate material. The spacer 30 is formed by injection molding a synthetic resin.

[0021] As shown in FIG. 1, the bracket 10 is disposed on the outdoor side of the wall panel 2 and is connected to the fixing frame 40 while sandwiching the wall panel 2. As shown in FIGS. 2 and 3, the bracket 10 has a frame plate portion 11 having a substantially rectangular shape, and a window hole 12 having a substantially rectangular shape is formed in the frame plate portion 11. As shown in FIG. 1, the frame plate portion 11 abuts on the outdoor side surface of the wall panel 2, and as shown in FIG. 11, the window hole 12 faces the through hole 2a of the wall panel 2. The bracket 10 is formed to have a dimension that allows it to be inserted into the through hole 2a of the wall panel 2 from the indoor side toward the outdoor side.

[0022] As shown in FIG. 3(A), two fixing pieces 13 are provided at the upper and lower portions of the inner peripheral edge of the window hole 12, respectively. As shown in FIG. 3(B), each fixing piece 13 has an L-shaped side view. The base end portion of each fixing piece 13 projects from the inner peripheral edge of the window hole 12 to the outdoor side, and the tip end portion is bent inside the window hole 12 with the plate surface facing the window hole 12. A screw hole 13a is formed at the tip end portion of each fixing piece 13. As will be described later, a screw 4 (first connecting means) used for connecting to the fixing frame 40 is screwed into the screw hole 13a of each fixing piece 13.

[0023] The holder 20 is for holding the gas plug 3. As shown in FIG. 1, it is disposed on the outdoor side of the fixing frame 40 so as to face the fixing frame 40, is fixed to the spacer 30, and is fixed to the fixing frame 40 via the spacer 30.

[0024] As shown in FIGS. 2 and 4, the holder 20 has a bottom plate portion 21 having a substantially rectangular shape. Four screw holes 21a for attaching the gas plug 3 are formed in the bottom plate portion 21. The four screw holes 21a are arranged in a pair spaced apart in the horizontal direction and in a pair spaced apart in the vertical direction. A circular relief hole portion 21b is formed inside the virtual line connecting the four screw holes 21a.

[0025] At both ends of the upper and lower sides of the bottom plate portion 21, support piece portions 22 extending vertically to the bottom plate portion 21 and extending indoors are provided. The tip portions of the respective support piece portions 22 are fixed piece portions 23 bent at a right angle outward. In each fixed piece portion 23, a screw hole 23a is formed, and a notch recess 23b obtained by notching one corner portion at the tip in a rectangular shape is formed. Each notch recess 23b is formed such that the notch recess 23b and the corner portion of the fixed piece portions 23 adjacent to each other in the lateral direction face each other.

[0026] As shown in FIGS. 1 and 7, the gas plug 3 attached to the holder 20 has the plug portion 3a facing the indoor side, and the outdoor side portion is accommodated in the escape recess 21b. In the present embodiment, the gas pipe connection portion 3c of the gas plug 3 is directed downward in the piping direction, and the screw 5 inserted through the screw insertion holes 3b (see FIG. 2) located on both sides of the gas plug 3 when the plug portion 3a is viewed from its axial direction is screwed into the screw holes 21a (FIG. 4(A)) spaced apart in the lateral direction of the bottom plate portion 21. A flexible pipe F is connected to the gas pipe connection portion 3c.

[0027] As shown in FIG. 1, the spacer 30 is sandwiched between the holder 20 and the fixed frame 40 to secure the distance between the holder 20 and the fixed frame 40, and thus, the gas plug 3 held by the holder 20 is arranged at an appropriate position within the wall plate 2. As shown in FIGS. 2 and 5, it has a frame portion 31 on the indoor side which is the fixed frame 40 side, and four leg portions 37 on the outdoor side which is the holder 20 side. The frame portion 31 is formed in a substantially rectangular shape, and a window portion 32 facing the bottom plate portion 21 of the holder 20 is formed in the frame portion 31 in a substantially rectangular shape.

[0028] As shown in FIG. 5(A), engaging protrusions 33 protruding forward from the indoor side end surface of the frame portion 31 are formed at the central portions of two opposing side portions (the upper side portion and the lower side portion in the present embodiment) on the inner periphery of the window portion 32. The outer portions in the vertical direction of each engaging protrusion 33 are arc-shaped and protrude outside the inner periphery of the window portion 32 in a front view.

[0029] As shown in Fig. 2, the four legs 37 are arranged at the four corners of the frame portion 31, each having a substantially rectangular cross-section and extending outward in the outdoor direction. As shown in Fig. 5, each leg 37 has a screw insertion hole 37a that penetrates the spacer 30 in its extending direction, and has a contact surface 37b that contacts the fixing piece portion 23 of the holder 20 at the outdoor-side end portion.

[0030] A protrusion 38 is provided at one corner of each contact surface 37b, and the cross-section of the base end side of the protrusion 38 is substantially rectangular. As shown in Fig. 5(D), each protrusion 38 is arranged at the corner of each contact surface 37b that is outside in the vertical direction and inside in the horizontal direction.

[0031] As shown in Figs. 2 and 5, the concave end surfaces 31a, which are the indoor-side opening end surfaces of the two screw insertion holes 37a on the diagonal line (upper right and lower left in this embodiment) of the frame portion 31, are formed at positions recessed outside the indoor-side convex end surface 31b of the frame portion 31. The convex end surface 31b is configured to contact the fixed frame 40 as shown in Fig. 1.

[0032] The protrusions 38 of the four legs 37 are respectively inserted into the notch recesses 23b (Fig. 4(A)) of the four fixing piece portions 23 of the holder 20. Thereby, the spacer 30 and the holder 20 are positioned and are prevented from shifting in a direction intersecting the facing direction of the spacer 30 and the holder 20. At this time, the positions of the screw insertion holes 37a of the legs 37 and the screw holes 23a of the fixing piece portions 23 of the holder 20 are aligned.

[0033] As shown in Fig. 8, in the spacer 30 positioned on the holder 20, screws 6 are inserted into the upper right and lower left screw insertion holes 37a of the spacer 30. By screwing the screws 6 into the screw holes 23a of the fixing piece portions 23 of the holder 20, the spacer 30 and the holder 20 are connected and fixed.

[0034] As shown in FIG. 1, the indoor-outdoor length of the spacer 30 is set such that when the spacer 30 is fixed to the holder 20 and abuts against the fixing frame 40, the plug portion 3a of the gas plug 3 attached to the holder 20 is at a predetermined indoor-outdoor position from the fixing frame 40.

[0035] As shown in FIGS. 2 and 6, the fixing frame 40 is formed in a plate shape with a rounded rectangular outer shape, and as shown in FIG. 1, it is disposed on the indoor side surface of the wall plate 2 and is connected to the bracket 10 while sandwiching the wall plate 2. A window hole 41 is formed in substantially the central portion of the fixing frame 40. The window hole 41 faces the through hole 2a (FIG. 1) of the wall plate 2 and the window portion 32 (FIG. 5(A)) of the spacer 30 as shown in FIG. 16.

[0036] As shown in FIG. 6(A), the window hole 41 is substantially rectangular in shape and has substantially the same dimensions as the window portion 32 of the spacer 30. Engagement recesses 42 each having an arc shape are formed at the central portions in the left-right direction on two opposing side portions (the upper side portion and the lower side portion in this embodiment) of the inner periphery of the window hole 41.

[0037] As shown in FIG. 16, the upper and lower engagement protrusions 33 of the spacer 30 engage with the upper and lower engagement recesses 42 respectively. Thereby, the fixing frame 40 is positioned with respect to the spacer 30 based on the window hole 41, and thus is positioned with respect to the holder 20. At this time, the plug portion 3a of the gas plug 3 attached to the holder 20 is disposed at an appropriate position within the window hole 41 of the fixing frame 40.

[0038] As shown in FIG. 6(A), screw insertion holes 44 are formed in the upper left and lower right of the window hole 41 respectively. When the fixing frame 40 is positioned with respect to the spacer 30, the upper left and lower right screw insertion holes 44 respectively coincide with the positions of the upper left and lower right screw insertion holes 37a of the spacer 30 and the positions of the screw holes 23a of the upper left and lower right fixing piece portions 23 of the holder 20.

[0039] At this time, the screw 7 (second connecting means) inserted into the screw insertion hole 44 is screwed into the screw hole 23a of the holder 20 through the screw insertion hole 37a of the spacer 30. Thereby, the fixing frame 40 is connected and fixed to the holder 20 while sandwiching the holder 20 and the spacer 30.

[0040] At the central portions of the upper side portion and the lower side portion of the fixing frame 40, notches 45 that are cut out in a rectangular shape from the outer peripheral edge of the fixing frame 40 are formed, and positioning pieces 45a that protrude in the outdoor direction are provided at the bottom edge portions of the respective notches 45. The two positioning pieces 45a are arranged inside the upper and lower peripheral edge portions of the through hole 2a of the wall plate 2 to determine the position of the fixing frame 40 with respect to the through hole 2a.

[0041] At both end portions of the upper side portion and the lower side portion of the fixing frame 40, slit holes 46 that are cut out in the vertical direction from the outer peripheral edge of the fixing frame 40 are formed. The inner end portion 46a of the slit hole 46 has an arc shape.

[0042] The screw 4 (first connecting means) inserted into each slit hole 46 is screwed into the screw hole 13a of the fixing piece 13 of the bracket 10. Thereby, the fixing frame 40 is connected and fixed to the bracket 10 while sandwiching the wall plate 2.

[0043] Hereinafter, the mounting direction of the gas plug 3 to the wall plate 2 using the gas plug mounting device 1 having the above configuration will be described with reference to FIGS. 7 to 16. This mounting method is a gas plug retrofitting type mounting method in which the gas plug is mounted on the wall plate 2 from the indoor side after the construction of the wall plate 2. In the present embodiment, the case where the flexible pipe F is piped from below on the back side of the wall plate 2 will be described.

[0044] First, as shown in FIG. 7, with the gas pipe connection portion 3c of the gas plug 3 facing downward in the piping direction, attach the gas plug 3 to the holder 20 with the screw 5, and connect the flexible pipe F drawn out into the room from the through hole 2a of the already installed wall panel 2 to the gas pipe connection portion 3c. Next, pass the holder 20 with the gas plug 3 through the window hole 12 of the bracket 10. Incidentally, the flexible pipe F drawn out from the through hole 2a may be passed through the window hole 12 of the bracket 10 and then connected to the gas pipe connection portion 3c.

[0045] Next, as shown in FIG. 8, fix the spacer 30 to the holder 20 with the screw 6, and as shown in FIG. 9, fix the fixing frame 40 to the holder 20 with the screw 7. At this time, as shown in FIG. 10, a sub-assembly 50 is constituted by the holder 20 with the gas plug 3, the spacer 30, and the fixing frame 40. Incidentally, after the sub-assembly 50 is constituted, the flexible pipe F drawn out from the through hole 2a and passed through the bracket 10 may be connected to the gas pipe connection portion 3c.

[0046] Next, as shown in FIG. 11, move the bracket 10 from the through hole 2a to the outdoor side and arrange it on the outdoor side surface of the wall panel 2. The bracket 10 can be temporarily fixed to the wall panel 2 with an adhesive tape or the like. Next, as shown in FIGS. 12 and 13, screw the screw 4 into the screw holes 13a of the two lower fixing pieces 13 of the bracket 10 arranged on the outdoor side so that the head of the screw 4 protrudes into the room. Incidentally, after screwing the screw 4 into the bracket 10, the bracket 10 may be moved to the outdoor side. At this time, as shown in FIG. 12, pull the screw 4 to the indoor side to adjust the positions of the through hole 2a and the window hole 12 of the bracket 10.

[0047] Next, as shown in FIGS. 14 and 15, move the sub-assembly 50 with the holder 20 facing the outdoor side toward the screws 4, 4, and insert the shaft portions of the screws 4, 4 into the slit holes 46, 46 on the lower side of the fixing frame 40 of the sub-assembly 50. That is, let the shaft portions of the screws 4, 4 be received in the slit holes 46, 46 on the lower side of the fixing frame 40. In this embodiment, since there are screws 4 below each slit hole 46, the shaft portion of the screw 4 abuts against the inner end portion 46a of each slit hole 46. Therefore, the sub-assembly 50 is supported by the screws 4, 4.

[0048] Next, as shown in FIGS. 14 and 15, while pulling the screws 4, 4 toward the indoor side, rotate the sub-assembly 50 toward the outdoor side and insert it into the through-hole 2a, and bring the fixing frame 40 into contact with the indoor surface of the wall panel 2. At this time, the sub-assembly 50 is guided by the shaft portion of the screw 4. Therefore, the sub-assembly 50 can be easily inserted.

[0049] The protruding length of the screws 4, 4 into the room is set so that when the sub-assembly 50 is rotated toward the outdoor side around the intersection of the slit hole 46 and the shaft portion of the screw 4 (in this embodiment, the contact portion between the inner end portion 46a of the slit 46 and the shaft portion of the screw 4), the orbit of the sub-assembly 50 and the wall panel 2 forming the peripheral portion of the through-hole 2a do not interfere.

[0050] Next, as shown in FIGS. 1 and 16, fix the sub-assembly 50 inserted into the through-hole 2a to the fixing piece 13 of the bracket 10 with four screws 4. Then, by attaching the decorative plate 8 shown in FIG. 2 to the fixing frame 40, the installation of the gas plug 3 to the wall panel 2 is completed. At this time, the gas plug 3 is installed in a state of being built into the wall panel 2.

[0051] According to the above embodiment, after the construction of the wall panel 2, the gas plug 3 can be easily installed into the wall panel 2 from the room. By configuring the sub-assembly 50, the handling of these constituent members has become easier. Since the sub-assembly 50 can be inserted into the through-hole while being rotated, the space for attaching the gas plug can be reduced.

[0052] Note that the present invention is not limited to the above-described embodiments, and various modifications can be adopted without departing from the gist thereof. In the above embodiment, the flexible pipe F is piped from below, and the screw 4 is screwed into the fixing piece 13 at the lower part of the outdoor bracket 10, and the shaft part of the screw 4 is inserted into the slit hole 46 below the fixing frame 40 of the sub-assembly 50. However, when the flexible pipe F is piped from above, as shown in FIG. 17, the screw 4 may be screwed into the fixing piece 13 at the upper part of the outdoor bracket 10, and the shaft part of the screw 4 may be inserted into the slit hole 46 above the fixing frame 40 of the sub-assembly 50. In the above embodiment, the fixing frame 40 and the holder 20 are connected and fixed by sandwiching the spacer 30. However, without using the spacer 30, the length of the support piece part 22 of the holder 20 may be adjusted to secure the interval between the fixing frame 40 and the bottom plate part 21 of the holder 20. The interior material to which the gas plug 3 is attached may be a floor board.
