Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a lighting fixture such as a guide light provided inside a building or the like.

[0002]

[Prior Art]

 Conventionally, this type of lighting fixture has a built-in switch with a drawstring for inspecting the emergency charging block, a fluorescent lamp, etc. in the main body of the fixture, and a translucent display panel is provided on the front side of the main body of the fixture. The panel is printed with a sign indicating an emergency exit. When installing it in Amai, the bolt that penetrated the top of the fixture body was penetrated into the ceiling and tightened together with the nut. In this case, in order to ensure that the fixture body is horizontal and the display panel with signs printed is oriented in the vertical direction, fix the fixture body to the ceiling once and check the installation state, and if necessary, The work of revising and fixing again was repeated.

[0003]

[Problems to be solved by the device]

 In the conventional lighting fixture, when confirming the installation state of the main body of the fixture, the inclination etc. was checked by comparing it with the surrounding sky surface or wall surface, so a considerable distance that the surroundings can be seen I had to look at the equipment itself. For this reason, it is necessary to go to a distant place each time a correction is made, or to perform construction by two or more people, one fixing and fixing the work and the other checking, etc. Was needed.

An object of the present invention is to provide a lighting fixture that can be easily installed without the fixture body tilting with respect to the horizontal direction and the vertical direction.

[0005]

[Means for Solving the Problems]

 The luminaire of the present invention is provided with a longitudinal mark at a portion along the inner pulling string.

[0006]

[Action]

 The luminaire of this invention is provided with a vertical mark along the inner part of the drawstring. Therefore, by checking whether the mark and the drawstring are aligned in a straight line, the horizontal and vertical directions can be confirmed. The inclination with respect to can be easily confirmed.

[0007]

【Example】

 A lighting fixture according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 1 and 6, the luminaire 4 has a built-in switch 3 having a pull cord 2 at the lower end of which a knob 1 is suspended. The direction mark 6 is provided.

The switch 3 is a check switch in which the drawstring 2 is hung down. When the drawstring 2 is pulled while the power is on, a power failure occurs, and it is checked whether or not the emergency charging block 14 is functioning normally. be able to. At the lower end of the drawstring 2, there is suspended a knob 1 which is a metal weight and forms a ring for facilitating grasping by a finger or the like. The lighting fixture 4 is a box body in which a translucent display panel 4c is attached to the front side and side plates 4b are provided on both sides of the fixture body 4a. As shown in FIGS. 1 and 2, the instrument body 4a has a back plate 4e attached to the back surface thereof, and the emergency charging block 14 and the ballast 15 are laterally aligned and fixed. The switch 3 and the fluorescent lamp 12 are fixed to the respective lower parts. A pair of contact portions 11 are formed on the upper surface of the instrument body 4a. On the front side of the back plate 4e, a reflection plate 16 having a length shorter than that of the back plate 4e is attached at substantially the center in the longitudinal direction.

The portion 5 along the drawstring is a corner portion formed by the end surface 5a of the reflecting plate 16 and the front end portion 5b of the back plate 4e. The mark 6 is a combination of three holes 6a formed on the end surface 5a in the vertical direction in a straight line and three holes 6b formed in a straight line in the vertical direction in the vicinity of the front end 5b. Is. As shown in FIG. 4 (a), the contact portion 11 is a convex portion in which a part of the upper surface of the instrument body 4a is trapezoidally projected by pressing or the like, and the insertion hole 20 is formed in the central portion thereof. A circular arc-shaped elongated hole 22 is formed along the periphery of the insertion hole 20. A tilt correction tool 23 is provided on the lower surface of the contact portion 11. As shown in FIG. 4 (b), the inclination corrector 23 projects a slidable protrusion 24 along the inner periphery of the slot 22 from the slot 22 to the upper surface of the contact portion 11 to secure the screw insertion hole 26. A sleeve 25, which is formed at the upper portion of the peripheral edge of the screw insertion hole 26, is loosely inserted into the insertion hole 20. Reference numeral 13 denotes a socket for holding the fluorescent lamp 12. Although the mark 6 is shown as a circular hole, it may be a quadrangle, a triangle, or a protrusion.

To install the lighting fixture 4 on the ceiling surface 17, the pair of contact portions 11 are brought into contact with the ceiling surface 17 with the protrusion 24 positioned at the center of the elongated hole 22. As shown in FIGS. 4 (a) and 4 (b), screws 28 are inserted from below the contact portions 11, respectively, and these screws 28 are passed through the ceiling surface 17 to provide nuts (not shown). Tighten to. At this time, as shown in FIG. 2A, if the mark 6a and the drawstring 2 do not match, the instrument body 4a is inclined in the direction indicated by arrow A with respect to the vertical direction. When the inclination occurs, each protrusion 24 is moved along the elongated hole 22 to form a gap between the back side of the instrument body 4a and the ceiling surface 17, and as shown in FIG. Correct the posture so that 6a and drawstring 2 match.

On the other hand, as shown in FIG. 3A, if the mark 6b and the drawstring 2 do not match, the instrument body 4a is tilted upward with the side on which the switch 3 is attached as indicated by arrow B. Will be there. In this case, by tightening or tightening each screw 24 so that the protrusion 24 on the side closer to the switch 3 protrudes from the protrusion 24 on the opposite side, as shown in FIG. Correct the posture so that As shown in FIG. 5, a sleeve-shaped tilt correction tool 27 having a slope at the lower end may be used. In this case, the posture of the instrument body 4a is adjusted by appropriately tightening each screw 28 in a state where the inclination direction is opposite to the inclination of the instrument body 4a.

As described above, when the lighting fixture 4 is installed, the inclination correctors 23 and 27 provided on the pair of contact portions 11 are adjusted so that the marks 6a and 6b and the drawstring 2 are aligned on a straight line. Thus, the lighting fixture 4 can be easily fixed without tilting with respect to the horizontal direction and the vertical direction. Therefore, since the lighting fixture 4 can be attached and the posture can be corrected at the same time, the construction is easy without requiring much labor.

[0013]

[Effect of the device]

 The luminaire of this invention is provided with a vertical mark along the inner part of the drawstring. Therefore, by checking whether the mark and the drawstring are aligned in a straight line, the horizontal and vertical directions can be confirmed. The inclination with respect to can be easily confirmed. Therefore, when the instrument body is mounted on the ceiling surface or the like, the inclination can be corrected at the same time as fixing the instrument body. Therefore, one worker can perform the work efficiently, and the construction is easy without much labor.
