JP 2019-106268 A

Conventionally, guide lights are installed from the beginning of construction of the building in order to indicate the evacuation exit of the building. In this case, since the guide light is installed on the ceiling, the power supply wiring for the guide light is laid in the ceiling space, and a through hole for passing the power supply wiring is formed in the ceiling surface where the guide light is installed. A power line drawn out from the through hole is connected to the inside of the guide light. The guide light is fixed at a position overlapping the through hole of the ceiling surface.

On the other hand, when a new evacuation exit is provided in the building due to renovation or change of use of the building, it is necessary to newly install a guide light to indicate the evacuation exit. On the other hand, guide lights are designed on the premise that they will be installed from the beginning of the construction of the building as described above. Therefore, in the guide light, the opening through which the power line passes is formed in the top surface facing the ceiling, which is the installation surface. Therefore, when installing a new guide light on the ceiling of an existing building, it is necessary to lay a new power line in the ceiling and form a through hole in the ceiling to pull out the power line. Become. However, depending on the structure of the building, such construction is sometimes difficult and time-consuming.

The present disclosure has been made to solve the problems described above, and aims to provide a guide light adapter and a guide light installation method for easily installing a guide light on an existing ceiling. and

A guide light adapter according to the present disclosure is a guide light adapter for installing a guide light on a ceiling, and includes a main body. The main body is made of metal and has a cuboid shape. The body has a top wall, a bottom wall and four side walls. The top wall is rectangular. The bottom wall is located opposite the top wall. Four side walls connect the top wall and the bottom wall. The top wall includes a ceiling fixture for fixing to the ceiling. The bottom wall includes a guide light fixture for connecting the guide light and a bottom wall opening. At least one knockout portion is formed in each of the four side walls to form a side wall opening for inserting the wiring. The height of the side walls is 35 mm or more.

A guide light installation method according to the present disclosure includes the steps of preparing a guide light and the guide light adapter. A step of fixing the guide light adapter to the ceiling is carried out. In the side wall of the guide light adapter, a step of forming a side wall opening is performed by processing the knockout portion. A step of laying the wiring on the ceiling and introducing the end of the wiring into the guide light adapter through the side wall opening is performed. A step of connecting the ends of the wiring to the guide lights is performed. A step of installing the guide light to the guide light adapter is carried out.

According to the above, it is possible to obtain the guide light adapter and the guide light installation method for easily installing the guide light on the ceiling.

1 is a schematic perspective view of a guide light adapter according to an embodiment; FIG. FIG. 2 is a schematic diagram of the guide light adapter shown in FIG. 1; FIG. 2 is a schematic diagram showing a state in which a guide light is installed on the ceiling using the guide light adapter shown in FIG. 1; 4 is a flow chart for explaining a method of installing a guide light according to the present embodiment;

Embodiments of the present disclosure will be described below. In addition, the same reference numerals are given to the same configurations, and the description thereof will not be repeated.

<Configuration of guide light adapter>
FIG. 1 is a schematic perspective view of a guide light adapter 1 according to this embodiment. 2A and 2B are schematic diagrams of the guide light adapter 1 shown in FIG. FIG. 3 is a schematic diagram showing a state in which the guide light 100 is installed on the ceiling 110 using the guide light adapter 1 shown in FIG.

A guide light adapter 1 shown in FIGS. 1 to 3 is a guide light adapter 1 for installing a guide light 100 on a ceiling 110 and includes a main body 10 . The main body 10 is made of metal and has a rectangular parallelepiped shape. With such a rectangular parallelepiped shape, the strength of the main body 10 can be sufficiently secured. The main body 10 is formed by bending or pressing a steel plate and welding. The thickness of the steel plate forming main body 10 is, for example, 0.5 mm or more and 3.0 mm or less, more preferably 1.0 mm or more and 2.0 mm or less. By making the body 10 made of metal, the guide light adapter 1 can have sufficient strength. Therefore, the guide light 100 can be reliably supported by the guide light adapter 1 even in the event of a disaster such as a fire.

The body 10 has a top wall 11, a bottom wall 12 and four side walls 13, 14, 15, 16 as shown in FIG. The inside of the main body 10 is hollow. The planar shape of the upper wall 11 is rectangular. The size of the upper wall 11 is, for example, 40 mm on the short side and 138 mm or 208 mm on the long side. Since the size of the main body 10 is defined in this way, a sufficiently large cavity can be formed inside the main body 10 . Therefore, the cavities inside the main body 10 can accommodate components such as wiring or an adapter that connects the wiring and the guide light 100 as will be described later.

The upper wall 11 includes a ceiling fixing portion 11 a for fixing the guide light adapter 1 to the ceiling 110 . The ceiling fixing portion 11a has three or more screw holes 11a1 arranged at a distance of 25 mm or more. 1 and 2, five screw holes 11a1 are formed in the upper wall 11 as ceiling fixing portions 11a. Since three or more (preferably five) screw holes 11a1 are formed as the ceiling fixing portion 11a in this manner, the guide light adapter 1 can be installed even in a region of the ceiling 110 where there is no foundation (reinforcing material) such as a beam. can be easily fixed.

The plurality of screw holes 11a1 are arranged on a center line passing through the center of the short side of the upper wall 11 and parallel to the long side. Of the five screw holes 11 a 1 , the central screw hole 11 a 1 (third screw hole 11 a 1 from the end) is arranged substantially in the center of the upper wall 11 . The distances W1, W2, W3, and W4 between the multiple screw holes 11a1 may be the same, but may be different from each other. For example, among the five screw holes 11a1, the distances W2 and W3 between the three screw holes 11a1 located in the central portion of the upper wall 11 are set to the same value (for example, 30 mm). On the other hand, if the distances W1 and W4 between the two screw holes 11a1 located at both ends of the upper wall 11 and the other screw holes 11a1 adjacent to the two screw holes 11a1 are the same (for example, 29 mm). may The value of the distance W2 and the value of the distance W1 are different. Distance W2 and distance W3 are greater than distance W1 and distance W4. The distance W2 and the distance W3 may be different. The distance W1 and the distance W4 may be different. Here, the distances W1, W2, W3, and W4 mean the distances between the centers of adjacent screw holes 11a1.

Thus, when at least one of the distances W1, W2, W3, and W4 between the plurality of screw holes 11a1 is different from the other values, the degree of freedom regarding the installation position of the guide light adapter 1 on the ceiling 110 is increased. We can make it big. For example, consider a case where there are periodically areas on the ceiling 110 where screws cannot be fixed. At this time, since the distances between the screw holes 11a1 are different, the period of the area and the distance between the screw holes 11a1 become the same, and all the screws cannot be fixed to the ceiling, or the screws are guided to fix them to the ceiling. It is possible to suppress the occurrence of the problem of having to change the installation position of the lamp adapter 1 .

The bottom wall 12 is located opposite the top wall 11 . The bottom wall 12 includes a guide light fixture 12a for connecting the guide light 100, a bottom wall opening 12b, and two outer perimeter openings 12c. The two outer peripheral openings 12c are arranged so as to sandwich the bottom wall opening 12b. The guide light fixing portion 12a is two screw holes 12a1 formed in the bottom wall 12. As shown in FIG. Each of the two screw holes 12a1 is formed in a portion (two belt-like portions) of the bottom wall 12 arranged between the two outer peripheral openings 12c and the bottom wall opening 12b. That is, the bottom wall opening 12b is arranged between the two screw holes 12a1. The arrangement of the guide light fixing portion 12a is determined according to the arrangement of fixing screw holes on the top surface of the guide light 100 to which the guide light adapter 1 is applied.

Width W5 of bottom wall opening 12b in the direction in which two screw holes 12a1 are arranged is, for example, 70 mm or more. In this case, since the bottom wall opening 12b has a sufficient size, a tool or the like can be easily inserted into the guide light adapter 1 through the bottom wall opening 12b. When viewed from the direction perpendicular to the upper wall 11, the plurality of screw holes 11a1 as the ceiling fixing portion 11a of the upper wall 11 are arranged at positions overlapping the bottom wall opening 12b or the outer peripheral opening 12c. Therefore, in order to fix the guide light adapter 1 to the ceiling 110, when inserting and fixing a screw into the screw hole 11a1, a tool such as a screwdriver is inserted through the bottom wall opening 12b or the outer peripheral opening 12c. Easy to operate.

Four side walls 13 , 14 , 15 , 16 connect top wall 11 and bottom wall 12 . At least one knockout portion 13a, 14a, 15a, 16a is formed in each of the four side walls 13, 14, 15, 16 to form a side wall opening 17 for inserting the wiring. Knockout portions 13a, 14a, 15a, and 16a may have any configuration as long as side wall openings 17 can be formed. Therefore, by applying an impact to the knockout portions 13a, 14a, 15a, 16a, the knockout portions 13a, 14a, 15a, 16a can be easily removed from the side walls, and the side wall openings 17 can be formed.

At least one of the four side walls 13, 14, 15, 16 should have a knockout portion. Also, at least one of the four side walls 13, 14, 15, 16 may have a plurality of knockout portions. The arrangement of the knockout portions 13a, 14a, 15a, 16a on the side walls 13, 14, 15, 16 can be set arbitrarily. In this case, the side wall opening 17 used for drawing the wiring arranged on the ceiling 110 into the inside of the guide light adapter 1 can be formed at a position close to the ceiling 110 . Therefore, the wiring can be easily pulled into the guide light adapter 1 through the side wall opening 17 .

The wiring extends to the guide light adapter 1 via a wiring installation member 111 formed on the ceiling 110 as shown in FIG. As the wiring installation member 111 installed on the ceiling, for example, wiring pipes or moldings can be used. The wiring is inserted inside the pipe or molding. In the guide light adapter 1 shown in FIGS. 1 and 2, knockout portions 13a, 14a, 15a and 16a are provided at the central portions of the side walls 13, 14, 15 and 16 and adjacent to the upper wall 11, respectively. is formed. The size of the knockout portions 13a, 14a, 15b, 16a can be, for example, 15 mm wide and 6 mm high. The height H1 of the side walls 13, 14, 15, 16 is 35 mm or more. By sufficiently increasing the height H1 of the side walls 13, 14, 15, and 16 in this manner, a sufficient space can be formed inside the guide light adapter 1. FIG. Therefore, the wiring or the joint member for connecting the wiring and the guide light 100 can be easily stored inside the space.
