  However, in the invention described in Patent Document 1, since the contact piece and the plate-like body are provided at the eccentric position of the cover plate portion, the center position of the cover plate portion is set to the center position of the wall hole. It may be worn out of position. At this time, as shown by reference numeral 105 in FIG. 9, when the opening diameter of the wall hole is large, the opening portion of the wall hole 105 protrudes outside the cover board portion, which impairs the aesthetic appearance of the building or intrusions of dust or the like. This causes the problem that the room gets dirty. Therefore, the invention described in Patent Document 1 has a problem that it is difficult to mount the wall hole in an appropriate manner. Furthermore, in the invention described in Patent Document 1, the contact piece and the plate-like body are mounted in pressure contact with each other in the wall hole. However, the contact piece has a configuration in which the plate-like body is elastically deformed without changing its shape. Therefore, when the opening diameter of the wall hole is small, the amount of bending of the plate-like body becomes large. For this reason, there arises a problem that the plate-like body is likely to be deteriorated or damaged due to repeated use or long-term use.

  Further, in the invention described in the above-mentioned Patent Document 2, the structure becomes complicated by providing a sliding contact member or a locking piece on the plate-like body, and the cost becomes high. When attaching the closure lid, the locking piece must be locked to the locked portion, and there is a problem that the operation becomes complicated.

Is completed, the retaining portion 32 expands in the angular direction W and returns to its original state, so that the retaining portion 32 is locked.

  Next, two wall hole closing lids 10 are prepared, and the front end portion of the band portion 36 of the connecting member 35 is connected to the third through hole 43 from the surface side of the lid plate portion 14 of the one wall hole closing lid 10. Then, the stopper 38 is accommodated in the stopper accommodating portion 42 by being inserted through the third through hole 43 to the base end side of the band portion 36. As a result, the band portion 36 is sandwiched between the third through holes 43, and the stopper 38 is fixed in a state of being accommodated in the stopper accommodating portion 42.

  Then, the band portion 36 inserted through the one wall hole closing lid 10 is cut at an arbitrary location near the base end portion protruding to the back surface side of the lid plate portion 14. The first member (hereinafter simply referred to as “first member”) 51 using the wall hole closing lid 10 shown in FIGS.

  Next, the front end portion of the band portion 36 of the connecting member 35 is inserted into the first through hole 27 from the surface side of the cover plate portion 14 of the other wall hole closing lid 10, and further the base end portion side of the band portion 36 Until the first through hole 27 is inserted. At this time, the locking groove 37 of the band part 36 is inserted through the first through hole 27 so as to face the upper side (upper side shown in FIG. 4) of the cover board part 14. Then, the band portion 36 inserted through the other wall hole closing lid 10 is not cut. The second member (hereinafter simply referred to as “second member”) 52 using the wall hole closing lid 10 shown in FIGS. 7 and 8 is completed by the above steps.

  The working process when mounting the product using the wall hole closing lid 10 of this embodiment to the wall hole 12 will be described. First, the first member 51 and the second member 52 are prepared one by one. . Then, in each of the wall hole closing lids 10, the worker removes the lid portion 34 of the cap member 30 from the concave portion 26 and opens the lid portion 34.

  Next, the operator inserts the band portion 36 inserted through the wall hole closing lid 10 in the second member 52 into the wall hole 12, and then, as shown in FIG. Is made to face the opening 13 in a state in which it faces the opening 13 side of the wall hole 12.

  Then, as shown in FIG. 6, after one elastic piece 19 is inserted into the wall hole 12 and elastically deformed in the direction of the virtual center point 17, the sliding contact side edge 24 of the other elastic piece 19 is obtained. Is brought into contact with the opening 13 and a pressing force in the direction of the opening 13 is applied while rotating the lid 14 clockwise as viewed from the operator (in the direction of arrow R shown in FIG. 6). Then, the other elastic piece 19 is elastically deformed in the direction of the virtual center point 17. Even if the elastic piece 19 is elastically deformed, the shape of the fixing portion 18 does not change.

  Here, as described above, the elastic piece portion 19 has a height direction size H that decreases from the base end portion 21 side to the tip end portion 22 side, and is formed in a substantially linear shape on the opposite side to the lid portion 14. The slidable contact side edge portion 24 is inclined in a direction in which the tip portion 22 side is close to the cover plate portion 14. For this reason, the sliding contact edge 24 is slid onto the opening 13 by applying a pressing force in the direction of the opening 13 to the lid 14 with the sliding contact edge 24 in contact with the opening 13. The elastic piece 19 is elastically deformed naturally in the direction of the imaginary center point 17 of the lid 14 while contacting.

  Then, due to the elastic deformation of the elastic piece portion 19, the contact position of the sliding contact side edge portion 24 with the opening portion 13 moves toward the distal end portion 22 of the elastic piece portion 19, and the opening portion 13 of the sliding contact side edge portion 24. When the contact position moves to the tip 22 of the other elastic piece 19, the entire elastic piece 19 is inserted into the wall hole 12.

  Further, when a pressing force in the direction of the opening 13 is further applied to the lid 14, and the plate surface of the lid 14 is brought into contact with the opening 13, the second member 52 of the second member 52, as shown in FIGS. The lid 14 of the wall hole closing lid 10 is in a state of covering the entire surface of the opening 13. 7 and 8, the left side of the pair of wall hole closing lids 10, 10 corresponds to the wall hole closing lid 10 of the second member 52. In this state, each of the pair of elastic pieces 19, 19 is elastically deformed inside the wall hole 12 and pressed into the wall hole 12, and the wall hole closing lid 10 is fixed to the wall hole 12 by this pressure contact force. Is done. 7 and 8, the wall hole closing lid 10 of the second member 52 is fixed to the wall hole 12 while maintaining the vertical direction shown in FIGS. The locking groove 37 is arranged in a state of facing upward.

  Then, the operator fits the lid portion 34 of the wall plate closing lid 10 of the second member 52 fixed to the wall hole 12 into the concave portion 26 and closes the lid portion 34. Thereby, when viewed from the front surface side of the lid part 14, the connection member 35 and the through holes 27, 28, and 43 through which the connection member 35 penetrates are hidden by the lid part 34.

  Next, the operator places the wall hole closing lid 10 of the first member 51 in the state in which the wall hole closing lid 10 of the second member 52 is aligned in the vertical direction (that is, FIGS. 7 and 8). In FIG. 1 to FIG. 4, the vertical direction is maintained, and the wall 13 is brought close to the opening 13. Then, the leading end portion of the band portion 36 of the second member 52 is inserted into the first through hole 27 from the back surface side of the lid portion 14 in the wall hole closing lid 10 of the first member 51, and the band portion 36 is inserted. The front end side of the head is projected to the surface side of the cover part 14. At this time, the locking groove 37 of the band portion 36 is engaged and locked with the locking tongue piece 40 of the connecting member 35 fixed to the wall hole closing lid 10 of the first member 51.

  In this state, the elastic hole 19 is inserted into the wall hole 12 and the wall hole closing lid 10 of the first member 51 is inserted into the wall hole 12 by the same procedure as the wall hole closing lid 10 of the second member 52. 7 and FIG. 8, the wall hole closing lid 10 is fixed to the wall hole 12 in a state in which the lid 14 closes the entire surface of the opening 13. 7 and 8, the wall hole closing lid 10 of the first member 51 is shown on the right side of the pair of wall hole closing lids 10, 10. Further, the operator rotates the cover plate portion 14 of the wall hole closing lid 10 of the first member 51 so that the vertical direction coincides with the wall hole closing lid 10 of the second member 52. Adjust so that

  By the above procedure, as shown in FIGS. 7 and 8, both the openings 13 of the wall hole 12 are closed by the pair of wall hole closing lids 10, 10.

  In this state, the pair of elastic pieces 19, 19 of the wall hole closing lid 10 are elastically deformed in the direction of the fixed portion 18, and are pressed against the inner peripheral portion of the wall hole 12. At this time, since the pair of elastic pieces 19 and 19 are elastically deformed, the amount of bending of the elastic pieces 19 and 19 can be small. In addition, since the fastening piece portions 16 and 16 are disposed at substantially symmetrical positions with respect to the virtual center point 17 of the lid plate portion 14, the elastic force of the elastic piece portions 19 and 19 is applied to the lid plate portion. 14 are added equally toward the direction of the virtual center point 17. Therefore, when the wall hole closing lid 10 is attached to the wall hole 12, the positions of the center of the wall hole 12 and the virtual center point 17 of the cover board portion 14 are substantially coincident with each other.

  Then, the operator grasps the front end side of the band portion 36 protruding from the surface side of the lid plate portion 14 in the wall hole closing lid 10 of the first member 51, and holds the band portion 36 of the lid plate portion 14. The band portion 36 that is pulled out to the front surface side and slacks inside the wall hole 12 is in a tensioned state. The locking tongue piece 40 of the connecting member 35 of the first member 51 meshes with the locking groove 37 of the band part 36 to lock the band part 36, and the band part 36 is kept in a tensioned state. Thus, the state in which the pair of wall hole closing lids 10 and 10 are fixed to the wall hole 12 by the tension of the band portion 36 is maintained, and the pair of wall hole closing sounds fixed to the wall hole 12 is retained. A situation in which the lids 10, 10 fall from the wall hole 12 can be prevented. Further, as shown in FIGS. 7 and 8, the operator turns back the band portion 36 drawn out from the first through hole 27 of the first member 51 to the surface side of the lid plate portion 14 to return the second through hole 28. The tip of the band portion 36 is accommodated in the wall hole 12. Thereby, the situation where the long band part 36 is exposed to the outside of the lid part 14 and the aesthetic appearance is impaired can be prevented.

  After the above operation is completed, the operator closes the lid 34 by fitting the lid 34 of the wall plate closing lid 10 of the first member 51 into the recess 26. Thereby, when viewed from the front surface side of the lid part 14, the connection member 35 and the through holes 27, 28, and 43 through which the connection member 35 penetrates are hidden by the lid part 34.

  Thus, in this embodiment, the wall hole closing lid 10 of the second member 52 is attached to the opening 13 on one side of the wall hole 12, and then the wall hole closing lid of the first member 51 is attached. 10 can be attached to the opening 13 on the other side of the wall hole 12. That is, the operation of attaching the pair of wall hole closing lids 10 and 10 to the both side openings 13 and 13 of the wall hole 12 is the same as the operation of attaching the wall hole 12 to the opening 13 on one side and the opening on the other side. Therefore, even if there is only one worker, the work can be easily performed.

  By the way, for example, when the opening diameter of the opening portion 13 of the wall hole 12 is very small with respect to the diameter of the cover plate portion 14, the outer peripheral portion of the cover plate portion 14 is not necessary for closing the opening portion 13. On the other hand, when the wall hole 12 is provided in the vicinity of an obstacle (for example, a ceiling or a fence of a building), when the wall hole closing lid 10 is attached to the opening 13 of the wall hole 12, the lid A part of the board part 14 comes into contact with an obstacle to create a gap between the opening part 13 and the cover board part 14, or the wall hole closing lid 10 is attached to the opening part 13 of the wall hole 12. Things that can't be done can happen. In such a case, the operator cuts out a part of the cover board part 14 along the cut groove 33 to cut out a part that is not necessary for closing the opening part 13 of the cover board part 14. Then, the operator attaches the wall hole closing lid 10, which is a part of the lid 14, to the opening 13 of the wall hole 12. By doing in this way, the opening part 13 of the wall hole 12 can be plugged, preventing a part of the cover part 14 from contacting an obstacle.

  As described above, in this embodiment, the fastening means 15 is composed of the fixing portion 18 erected on the center side of the lid plate portion 14 and the plate body that can be elastically deformed, and one end portion is fixed. A pair of fastening pieces 16 each having an elastic piece 19 that is joined to the portion 18 and extends toward the outer peripheral portion of the lid 14 and is pressed into the wall hole 12 are provided. As a result, when the fastening means 15 is inserted into the wall hole 12, the pair of elastic pieces 19, 19 are elastically deformed in the direction of the fixed portion 18, and are pressed against the inner peripheral portion of the wall hole 12. At this time, since the pair of elastic pieces 19 and 19 are elastically deformed, the amount of bending of the elastic pieces 19 and 19 is small, and the load on the elastic pieces 19 due to the bending becomes excessive. Can be prevented. Further, the fastening pieces 16, 16 are disposed substantially symmetrically with respect to the virtual center point 17 of the lid 14, and the center of the wall hole 12 and the lid before being attached to the wall hole 12. When the virtual center point 17 of the board part 14 is made to coincide with each other, the tip parts 22 and 22 of the respective elastic piece parts 19 and 19 protrude outward from the peripheral part 23 of the opening part 13 of the wall hole 12. At the same time, in the state of being mounted in the wall hole 12, the tip portions 22, 22 of the respective elastic piece portions 19, 19 are elastically deformed in the direction of the imaginary center point 17 of the cover plate portion 14 and are pressed into the wall hole 12. The wall hole closing lid 10 can be attached to the wall hole 12 in a state where the center position of the wall hole 12 and the virtual center point 17 of the cover board portion are substantially coincided with each other. it can. Therefore, even when the opening diameter of the wall hole 12 is large, it is possible to easily prevent a situation in which a part of the opening 13 of the wall hole 12 protrudes outside the lid part 14. Furthermore, since the elastic piece portion 19 is not provided with a complicated configuration such as a pressing member or a locking piece, it is not necessary to use a mold having a complicated configuration when manufacturing the wall hole closing lid 10, Increase in manufacturing costs can be prevented. As a result, it can be manufactured at a low cost with a simple configuration, and the wall hole can be closed without any gap regardless of the size of the wall hole, and it is not easily deteriorated or damaged by repeated use or long-term use. A wall hole closing lid that can be attached to the wall hole can be provided.

  Further, in this embodiment, the pair of elastic pieces 19 and 19 are disposed with their plate surfaces facing each other substantially in parallel, and the respective distal end portions 22 and 22 are each proximal end portion 21. , 21 are extended in opposite directions with respect to the imaginary line 25, so that the fastening means 15 is inserted into the wall hole 12 and the elastic pieces 19, 19 are crimped to the wall hole 12. When this is done, substantially the same elastic force can be applied from the substantially symmetric position to the virtual center point 17 of the cover board part 14 toward the virtual center point 17 direction of the cover board part 14. As a result, when the wall hole closing lid 10 is attached to the wall hole 12, the center position of the wall hole 12 and the virtual center point 17 of the cover panel portion can be easily set only by the elastic force of the respective elastic pieces 19 and 19. To provide a wall hole closing lid 10 that can be substantially matched with each other, can reliably close the wall hole regardless of the size of the wall hole 12, and can be attached to the wall hole 12 more easily. Can do.

  In this embodiment, a recess 26 is formed in a part of the lid 14, and a pair of wall hole closing lids 10, 10 are formed in the recess 26 in the pair of openings 13, 13 of the wall hole 12. A first through hole 27, a second through hole 28, and a third through hole 43 are formed through which the connecting members 35 for connecting the respective wall hole closing lids 10, 10 to each other in a state of being mounted, A cap member 30 that is fitted into the recess 26 in a state of covering each of the through holes 27, 28, 43 is provided, and an attachment piece 31 is extended to the cap member 30, In the case of insertion into the mounting hole 29 formed in the recess 26, the retaining part 32 is elastically deformed so that the retaining part 32 can be inserted into the mounting hole 29. After the insertion is completed, the retaining portion 32 returns to its original state and is removed. By forming the portion 29 to be locked, the retaining portion 32 is inserted into the mounting hole 29 by press-fitting the retaining portion 32 into the mounting hole 29, and the retaining portion 32 penetrating the mounting hole 29 is retained. Can be made. Therefore, the attaching process of the cap member 30 can be easily performed only by press-fitting the retaining portion 32. Then, by fitting the cap member 30 with the retaining portion 32 locked into the recess 26, the connecting member 35 and the through holes 27, 28, 43 through which the connecting member 35 penetrates are exposed to the outside and the aesthetic appearance is impaired. The situation can be prevented.

  In this embodiment, in the vicinity of the outer peripheral portion of the plate surface of the lid plate portion 14, a linear cut groove 33 for excising a part of the lid plate portion 14 is formed to be depressed, so that the lid plate It becomes possible to easily cut the outer peripheral portion side than the cut groove of the portion 14. Thereby, when a part of the lid part 14 that is not necessary for closing the wall hole 12 is generated, a part of the lid part 14 can be easily removed, and the wall hole closing lid 10 can be removed. Can be more easily attached to the wall hole.
