Description

Light fixture seismic hanger {EARTHQUAKE-PROOF HANGER FOR MOUNTING LIGHTING DEVICE}

The present invention relates to a luminaire seismic hanger, and more particularly, to a luminaire seismic hanger capable of mounting a luminaire to a ceiling in a building.

In general, the ceiling of offices, factories, hospitals, hotels, schools, government offices, etc. for performing various tasks is fixedly installed with M-bars, which are arranged in a lattice form, and plaster using the embar as a ceiling finishing material As the tex is continuously fixedly installed, the interior ceiling may be finished. At this time, in the indoor ceiling as described above, ceiling lights in various forms such as ceiling ceiling lights, suspended ceiling lights, etc. may be mounted and fixed to the embar.

On the other hand, Korea is also not a safe country from earthquakes, and in recent years, an active fault has been further discovered. Therefore, in the case of a ceiling lamp having a conventional fixed installation structure, when the earthquake occurs, the ceiling lamp may be moved back and forth and left and right due to the installation tolerance between the ceiling finishing material and the ceiling lamp, and thus the fixing power may be lost. As a result, damage to the ceiling itself may occur, as well as serious personal injury.

Therefore, a seismic design has been made on the recently developed ceiling light to prevent the fixing force from being lost due to the vibration caused by the earthquake. For example, a seismic design has been made to absorb vibrations caused by an earthquake by mounting a spring on a hanger or bracket that mounts a ceiling lamp on an embar.

The hanger or bracket having such a seismic design needs to be fixed over the embar installed in the ceiling of the building. That is, the worker can first mount the hanger or bracket to the ceiling, etc., and then connect it over the embar and fix it through a bolt or nut. However, since the work of fixing the bolts or nuts by rotating them is performed on the ceiling, the work efficiency can be greatly deteriorated since it can be very difficult for the operator performing the work.

That is, the upper hanger stopper plate 232 may be formed to protrude from one end of the upper hanger main plate 210 to cover at least a portion of the outer surface of the lower hanger stopper plate 142.

The upper hanger stopper protrusion 234 may be formed to protrude from an inner surface of the upper hanger stopper plate 232 to correspond to the lower hanger stopper protrusion 144. The upper hanger stopper protrusion 234 may have a stepped shape at a right angle to the upper end which may contact the lower end of the lower hanger stopper protrusion 144, but may have a rounded shape with an inclined bottom.

The trigger protrusion 236 may be formed to protrude from the upper hanger stopper plate 232 to correspond to the trigger hole 142a. For example, the trigger protrusion 236 may be formed to protrude toward the trigger hole 142a from a portion of the lower end of the upper hanger stopper plate 232 facing the trigger hole 142a.

As described above, the luminaire seismic hanger, when the upper end of the upper hanger stopper protrusion 234 is in contact with the lower end of the lower hanger stopper protrusion 144 as shown in Figure 9, the lower hanger main plate 110 ) And the angle between the upper hanger main plate 210 is fixed to be the reference angle, and may be operated in the open mode.

On the other hand, the luminaire seismic hanger, when the trigger unit 400 is pushed upward by the operator to move the trigger projection 236 by the trigger direction changing unit 160 to move outward, the The upper end of the upper hanger stopper protrusion 234 may be released from engagement with the lower end of the lower hanger stopper protrusion 144. As a result, the upper hanger main plate 210 so that the angle between the lower hanger main plate 110 and the upper hanger main plate 210 becomes an angle lower than the reference angle by the pressing force by the torsion spring 320 ) Is rotated based on the rotation axis of the rotation shaft rod, and thus may be operated in the closed mode.

Meanwhile, the upper hanger unit 200 may further include a luminaire mounting bar cover part 240.

The luminaire mounting bar cover portion 240 may be formed to extend downward from the other end of the upper hanger main plate 210 to face the upper hanger stopper plate 232. The luminaire mounting bar cover portion 240 is the upper hanger main plate 210 so that the angle between the lower hanger main plate 110 and the upper hanger main plate 210 is lower than the reference angle Rotating about the rotation axis of the rotating shaft rod when pressing the luminaire mounting bar 10 may cover one side of the luminaire mounting bar (10).

In addition, at least one bent portion may be formed on the upper hanger main plate 210. The bent portion is rotated based on the rotation axis of the rotating shaft rod so that the angle between the lower hanger main plate 110 and the upper hanger main plate 210 is an angle lower than the reference angle When the luminaire mounting bar 10 is pressed, a portion of the luminaire mounting bar 10 may be accommodated to improve the coupling force with the luminaire mounting bar 10.

For example, when the luminaire mounting bar 10 is an M-shaped embar, the upper hanger main plate 210 includes a first upper hanger bend 212 for accommodating the two pillars of the embar, respectively. A second upper hanger bend 214 may be formed.

As described above, according to the present embodiment, when the luminaire seismic hanger is coupled to the upper end of the upper hanger stopper protrusion 234 in contact with the lower end of the lower hanger stopper protrusion 144, the operator is operated in the open mode. The luminaire seismic hanger is first coupled with the luminaire through the luminaire coupling portion 120, and then can be easily inserted into a luminaire mounting hole in any building ceiling.

Thereafter, when an operator pushes and moves the trigger unit 400 upward with one touch, the upper end of the upper hanger stopper protrusion 234 is released from the lower end of the lower hanger stopper protrusion 144, so that the The luminaire seismic hanger can be changed from the open mode to the closed mode, whereby the luminaire seismic hanger can be easily mounted on the luminaire mounting bar 10. Therefore, since a mechanism such as an electric screwdriver is not required for fixing to the luminaire mounting bar, the efficiency of work can be much improved.

In the detailed description of the present invention described above, it has been described with reference to preferred embodiments of the present invention, but those skilled in the art or those skilled in the art will appreciate the spirit of the present invention as set forth in the claims below.
