An indicator 100 according to an embodiment of the present invention displays the planned installation position of an inspection hole formed in a wall for maintenance and inspection of equipment in a space behind the wall. In this embodiment, the equipment is exemplified as an air conditioner such as an indoor unit of an air conditioner, but it may be other equipment such as a ventilation fan or the like installed on the ceiling.

FIGS. 1(a) and 1(b) are schematic perspective views of the display device 100 of this embodiment. FIGS. 2(a) to 2(d) are a plan view, a left side view, a front view, and a right side view of the display device 100. FIG. 3 is an exploded perspective view of the display device 100.

As shown in FIGS. 1 and 2, the display device 100 includes a frame member 101 that extends in a direction substantially parallel to the (indoor side) wall and away from the equipment when installed, and a frame member 101 that extends away from the equipment. It includes a fixing member 111 for fixing to the frame member 101 and a hanging member 121 attached to the frame member 101. The frame member 101 is formed as a display section in the space behind the wall to display the opening area of the inspection port in the wall and the inspection space where the opening area extends linearly from the wall to the back side of the wall (see FIG. 9, etc.). ). Furthermore, the fixing member 111 was formed as a fixing part that fixes the display section at a position where the display section can display the opening area and the inspection space (see FIG. 9, etc.). Further, the hanging member 121 is formed to hang downward from the frame member 101 so as to be easily noticed by the user, thereby making the construction worker aware of the presence of the display device 100.

The frame member 101 includes a pair of extension parts 102, 102 that extend in a long length from the base end toward the distal end, and a bridge part 106 that bridges the ends of the pair of extension parts 102, 102 and connects them. has. The frame member 101 has a U-shaped frame shape that is open toward the base end by a pair of extending portions 102, 102 and a bridge portion 106.

The pair of extended portions 102 are each formed into a long plate shape, and have inner surfaces facing each other and outer surfaces facing opposite to each other. The extension part 102 extends in a direction away from the equipment when installed, and has a length that allows it to display, as a display part, the opening area of an inspection port to be installed on a wall. Moreover, the pair of extension parts 102, 102 are separated by a distance that allows the opening area to be displayed as a display part. An engaging portion 103 that abuts and engages with the outer surface of the equipment (fixed object) is formed on the proximal end side of each of the extending portions 102 relative to the equipment (or the fixing member 111).

The bridge portion 106 connects the pair of extending portions 102, 102 so that the pair of extending portions 102, 102 remain parallel and separated by a predetermined distance. As shown in FIG. 3, one end of the bridge section 106 is fixed to the inner surface of one of the extending sections 102. That is, the bridge portion 106 has a fixed end 106a at one end and a free end 106b at the other end, and is tiltable and deformable about the fixed end 106a as a fulcrum. In other words, the bridge portion 106 is movable from a position superimposed on one extending portion 102 to a position facing the other extending portion 102 . An assembly groove 106c that opens downward is formed at the lower edge of the bridge portion 106 near the free end 106b. Further, a first connecting groove 107 that opens upward is formed at the upper edge of the other extending portion 102 . The first connecting groove 107 is arranged at the same position as the fixed end 106a of the bridge portion 106 in the longitudinal direction. The assembly groove 106c of the bridging portion 106 is disposed on the first connecting groove 107 of the other extension portion 102 and interlocks with each other. As a result, the free end 106b of the bridge portion 106 is fixed to the other extending portion 102. Furthermore, a second connecting groove 108 that opens downward is formed at the lower edge of the other extending portion 102 . The second connecting groove 108 is located closer to the base end than the first connecting groove 107 is. In a second form of display device 100′, which will be described later in FIG. .

A fixing member 111 is removably attached to the base end side of each extending portion 102 so as to be perpendicular to the extending portion 102 . As shown in FIG. 3, the fixing member 111 is separate from the extension portion 102 and has a longitudinal plate shape. The length of the fixing member 111 is shorter than the length of the extension portion 102. The fixing member 111 has a back surface facing the proximal end side and a front surface facing the distal end side, and has an abutting surface 112 on the back surface that abuts and is fixed to the outer surface of the equipment. In this embodiment, the fixing member 111 is attached to the outer surface of the equipment using curing tape, double-sided tape, or the like so that it can be easily removed later.

The fixing member 111 is formed with a first slit 113 and a second slit 114 extending along its longitudinal direction. The fixing member 111 is configured to be inserted into the first and second slits 113 and 114 and integrated with the extension portion 102. The first slit 113 and the second slit 114 have the same slit length, but the second slit 114 has a larger slit width than the first slit 113. A locking piece 104 is provided on the outer surface of each extending portion 102 to restrict movement of the fixing member 111 toward the distal end side. In other words, the extending portion 102 has a thick portion (step) due to the locking piece 104 . The first slit 113 has a slit width that allows the base end (thin portion) of the extended portion 102 to pass through, but restricts the passage of the locking piece 104 . That is, as shown in FIG. 7A, the proximal end surface of the locking piece 104 functions as a first locking portion 104a that locks the fixing member 111 moving toward the distal end. That is, the first locking portion 104a locks the fixing member 111 at a predetermined position of the extension portion 102, thereby positioning the fixing member 111. Here, the length from the fixed member 111 to the tip of the extension portion 102 corresponds to the length of the frame member 101 extending from the equipment. On the other hand, the second slit 114 has a slit width that allows the locking piece 104 to pass through a thick portion. In a second form of the display device 100 (see FIGS. 4 to 6), which will be described later, the vertical protrusion or step (second locking portion 104b) on the tip side of the locking piece 104 is in contact with the periphery of the second slit 114. By engaging, the fixing member 111 that moves toward the distal end is locked at a predetermined position.

The frame member 101 forms a U-shape with the pair of extending portions 102 and the bridging portion 106. When the frame member 101 is attached to the outer surface of the equipment, it cooperates with the outer surface of the equipment to form a frame having a shape and size that allows the outer periphery of the opening area to be surrounded or sandwiched from the space behind the wall. . In other words, the open area and the inspection space are included inside this closed frame. In this embodiment, it is preferable that the inner dimensions and shape of the frame formed by the frame member 101 are substantially the same as the dimensions and shape of the opening area of the inspection hole that is planned to be drilled in the wall. Since the internal dimensions and shape of the frame formed by the frame member 101 correspond to the dimensions and shape of the opening area, the construction worker can accurately grasp the position of the opening area, and the space behind the wall can be used more efficiently. This is because it becomes possible. Alternatively, the inner dimensions and shape of the frame member 101 are preferably similar to the opening area so that the construction worker can imagine the outline of the opening area. In addition, in the display device 100 of this embodiment, the extended length and width (inner dimension) of the frame member 101 are approximately It is 600mm.

In this embodiment, the frame member 101 was formed from paper cardboard. Since paper cardboard is a combustible material, it has the advantage of being easy to separate and dispose of as garbage and being inexpensive. Furthermore, since paper cardboard also has a function as a cushioning material, the frame member 101 can be folded and packed together with equipment as a cushioning material. However, the frame member of the present invention may be made of any material such as wood, metal, or synthetic resin.

Furthermore, a hanging member 121 is installed between the pair of extension portions 102 . The hanging member 121 extends in a plane and is made of a flexible material such as cloth or film. The hanging member 121 extends a predetermined length from one end to the other end, and has one end attached to one extending portion 102 and the other end attached to the other extending portion 102 . The length of the hanging member 121 is greater than the distance between the pair of extension parts 102, 102. Therefore, the hanging member 121 hangs down from the frame member 101. The hanging member 121 functions to make the construction worker aware of the presence of the display device 100, for example, by hanging down toward the inspection port after installation on the wall.

The display device 100 of this embodiment can be deformed so that the size and shape of the frame can be changed from the first form shown in FIGS. 1 to 3 so as to correspond to opening areas of different shapes and sizes. 4 to 6 show a second form of indicator 100' that has been modified to accommodate an aperture area of smaller geometry.

As shown in FIGS. 4 to 6, in the display device 100', one extension part 102 is close to the other extension part 102, and the other extension part 102 is arranged upside down. . In this embodiment, the hanging member 121 is wound around the extension portion 102 to adjust the amount by which the hanging member 121 hangs down. However, without wrapping the hanging member 121 around the extending portion 102, the hanging member 121 may be made to hang further downward as the pair of extending portions 102, 102 are closer to each other. Furthermore, the fixing member 111 is similarly arranged upside down. The proximal end of the extending portion 102 is inserted into the wide second slit 114 of the fixing member 111 . Since the second slit 114 allows the first locking portion 104a of the locking piece 104 to pass through, the fixing member 111 is disposed closer to the distal end side of the extending portion 102 than in the first embodiment. Then, as shown in FIG. 7(b), the peripheral edge of the second slit 114 is locked to the second locking part 104b of the locking piece 104, so that the fixing member 111 is positioned on the extension part 102. ing. Therefore, in the display devices 100, 100' of the present embodiment, the fixing member 111 is arranged so that the extension length of the frame member 101 from the equipment can be adjusted in stages according to the size of the opening area. 101 can be fixed. Further, the bridging portion 106 extends diagonally from one extending portion 102 to the other extending portion 102, and the assembly groove 106c of one extending portion 102 is arranged on the second connecting groove 108. are interwoven with each other. Therefore, in the display devices 100, 100' of this embodiment, the width of the frame member 101 can also be adjusted stepwise.

That is, in the display device 100' of the second form, the frame member 101 forms a frame that can surround or sandwich a smaller area than in the first form for display. Specifically, in this modified display device 100', the extended length and width (inner dimension) of the frame member 101 are approximately 450 mm so as to correspond to an inspection port having a 450 mm square opening (opening area). It is.

Further, the display device 100 can be folded compactly like the display device 100" shown in FIG. 8. That is, from the form of FIG. 1 or FIG. The free end 106b of the bridging part 106 is removed from the other extending part 102 and overlapped with one extending part 102.Then, by bringing the pair of extending parts 102, 102 connected by the hanging member 121 close to each other, , the display device 100 can be folded compactly. In this compact form, the display device 100 can be packed together with the equipment 13 and the like as a cushioning material, as described above.

Next, with reference to FIGS. 9 to 11, in the space behind the wall where the indoor wall (or wall) constituting the double ceiling is planned to be constructed together with the structural wall on the outer wall side, display devices are placed on the equipment 13. The installation structure 10 in which the device 100 is installed will be explained. FIG. 9 is a schematic perspective view schematically showing an installation structure 10 according to an embodiment of the present invention. FIG. 10 is a schematic side view of the installation structure 10. FIG. 11 is a schematic plan view of the installation structure 10. Here, the indoor wall (or its planned installation location) that defines the back wall space on the back side is represented by the reference numeral 11. The installation space for wiring and piping materials (or their planned installation locations) is represented by the reference numeral 14. The opening area drilled into the indoor wall to construct the access port is designated by the reference numeral 15. The inspection space whose opening area extends linearly from the indoor wall to the back side of the wall is designated by the reference numeral 16.

The equipment 13 has a box shape and has a maintenance inspection target portion 13a on one side. For example, the maintenance inspection target portion 13a may be a filter of an air conditioner, a ventilation fan, or the like, or a pipe connection portion. The inspection port is arranged in a predetermined positional relationship with respect to the equipment 13 in the space behind the wall. An inspection port is generally an opening that is normally closed by a lid. In the installation structure 10 of this embodiment, the inspection port is located adjacent to the side surface of the equipment 13 on which the maintenance inspection target part 13a is provided so that the maintenance inspection target part 13a can be accessed from the indoor side (wall surface). installed in position. According to design documents, etc., in order to form an opening in the wall 11 for the purpose of installing an inspection port, the installation range of the opening area 15 of a predetermined size (here, 600 mm square) is adjacent to the equipment 13. is defined on the virtual indoor wall 11. The construction worker then performs maintenance and inspection on the maintenance and inspection target portion 13a through the inspection space 16 that is connected to the opening area 15.

In the installation structure 10, the display device 100 is fixed to the side surface of the equipment 13 having the maintenance inspection target portion 13a. More specifically, the contact surface 112 of the fixing member 111 contacts the side surface of the equipment 13, and the fixing member 111 is attached to the side surface of the equipment 13 with a curing tape or the like. At this time, the engaging portion 103 on the base end side of the extending portion 102 is in contact with the bottom surface of the equipment 13. By engaging the engaging portion 103 with the bottom surface of the equipment 13, the tip of the display device 100 is prevented from tilting downward and falling off from the equipment 13.

The frame member 101 extends a predetermined length in a direction substantially parallel to the indoor wall 11 and away from the equipment 13 . Further, the frame member 101 has a frame shape that can surround or sandwich the outer periphery of the opening area 15 from the space behind the wall. The fixing member 111 fixes the frame member 101 so that the opening area 15 and the inspection space 16 are arranged inside the frame of the frame member 101. That is, the frame member 101 has a shape that displays a predetermined range when projected onto the wall 11 while being fixed by the fixing member 111, and the predetermined range includes at least the opening area 15 and the inspection space 16. Contains. Thereby, the frame member 101 displays, as a display section, an opening area 15 of the inspection port on the wall 11 and an inspection space 16 in which the opening area 15 extends linearly from the wall 11 to the back side of the wall. The construction worker can appropriately arrange the wiring/piping materials in the wiring/piping material installation space 14 in the space behind the wall according to the information displayed on the display unit. In other words, the presence of the display device 100 of this embodiment prevents the construction worker from erroneously arranging wiring and piping materials so as to interfere with the opening area 15 and the inspection space 16.

Further, the hanging member 121 hangs down from the frame member 101 toward the intended installation position on the indoor wall 11. Since this hanging member 121 is easily visible to the construction worker, it can make the construction worker aware of the presence of the display tool 100. It is preferable that the display device 100 is removed at a stage after the wiring and piping materials are appropriately arranged in the installation space 14 in the back wall space and before the wall 11 is constructed. This hanging member 121 serves to prevent the construction worker from forgetting to remove the indicator 100 before constructing the wall. Further, even after the wall 11 is constructed, the hanging member 121 faces the indoor side through the inspection opening, making it possible for the construction worker to notice that the display device 100 remains in the space behind the wall.

Next, a method of installing an inspection port at a predetermined position of a wall where wiring/piping materials are installed in the space behind the wall using the display device 100 of this embodiment will be described.

First, a method of constructing the installation structure 10 by attaching the display device 100 to the equipment 13 installed at a predetermined position in the space behind the wall will be described. Before the wiring and piping materials are laid and before the wall 11 is installed, a display device 100 that displays the opening area 15 of the inspection port and the inspection space 16 is fixed in the space behind the wall. The display device 100 is fixed to the equipment 13 via the fixing member 111 so that an opening area 15 in which an inspection port is installed and an inspection space 16 are arranged inside the frame of the frame member 101. In this embodiment, the fixing member 111 is easily attached to the outer surface of the equipment 13 using adhesive tape such as curing tape or double-sided tape. In addition, when the inspection port is installed at a position adjacent to the equipment 13, it is preferable that the display device 100 is directly fixed to the equipment 13 via the fixing member 111. However, when the equipment 13 and the inspection opening are separated by a predetermined distance, as long as the display section (frame member 101) displays the opening area 15 and the inspection space 16, the display device 100 cannot be used via an extension fitting or the like. It may be fixed indirectly to the equipment 13, or it may be fixed to a structure near the installation position of the inspection port. That is, by fixing the display device 100 at a predetermined position relative to the equipment 13, the installation structure 10 that displays the opening area 15 and inspection space 16 of the inspection port to be installed can be easily constructed.

Next, according to the display on the display device 100, wiring and piping materials are laid in the installation space 14 in the back wall space, avoiding the inspection space 16 in which the opening area 15 extends linearly from the wall 11 to the back side of the wall. Since the construction worker can visually check the installation space 14 outside the frame member 101, he can install wiring and piping materials in the installation space 14 without making mistakes.

After wiring and piping materials are installed in the installation space 14, the display device 100 is removed from the space behind the wall. At this time, since the hanging member 121 hangs down from the frame member 101, the construction worker can easily notice the presence of the display device 100, and the process is prevented from being forgotten. Moreover, since the display device 100 is simply attached to the equipment 13 with adhesive tape, it can be easily removed from the equipment 13.

After removing the display device 100 from the equipment 13, the steps of constructing the wall 11 and drilling the open areas 15 of the wall 11 to form an opening in the wall continue. By installing the inspection port in the opening, the inspection port can be installed at a predetermined position on the wall 11. Note that if the equipment is an air conditioner, it is necessary to separately form a hole for an air outlet in the wall, but the explanation thereof will be omitted here.

Note that if the step of removing the display device 100 from the space behind the wall is not performed before the step of installing the wall 11, it may be performed at least after the step of forming an opening in the wall 11. For example, after forming an opening in the opening area 15 of the wall 11, the display device 100 may be taken out from the opening. Alternatively, after installing an inspection port in the opening, the inspection port may be opened and the display device 100 may be taken out from the opening. Since the hanging member 121 of the display device 100 hangs down toward the opening, the construction worker can relatively easily notice that he or she has forgotten to remove the display device 100. Here, since the display device 100 has a U-shape, after removing it from the equipment 13, it can be pulled out from the opening of the inspection port installed in the wall 11 by changing its posture in the space behind the wall. be. Alternatively, by deforming the display device 100 into a shape that allows it to pass through an opening of an inspection port installed in the wall 11, it can be pulled out from the opening. Specifically, the frame member 101 of the display device 100 can be deformed by removing the fixed end 106a of the bridge portion 106 from the first connecting groove 107 so that the pair of extended portions 102, 102 are brought closer to each other. Furthermore, when the display device 100 is made of a fragile material such as paper cardboard, the display device 100 may be taken out from the opening by breaking, cutting, or bending the display device 100.

Hereinafter, the effects of the display device 100 according to one embodiment of the present invention will be described.

According to the display device 100 of the present embodiment, in the back wall space, the frame member 101 as a display portion fixed at a predetermined position by the fixing member 111 as a fixing portion, together with the opening area 15 of the inspection port on the wall 11. By also displaying the position of the inspection space 16 connected to the opening area 15, it is possible to prevent the construction worker from accidentally laying wiring, piping materials, etc. in the opening area 15 and the inspection space 16 directly above it. Can be done. In particular, even before the installation of the wall 11 or the laying of wiring and piping materials, the construction worker can install the opening area 15 of the inspection port and the inspection space 16 in the space behind the wall by using the display device 100. Scheduled locations can be visually confirmed. Therefore, the display device 100 of this embodiment can effectively reduce errors in laying wiring, piping materials, etc.
