Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a device for preventing a fluorescent lamp of a fluorescent lamp from falling off from a proper mounting position.
[0002]
[Prior art]
Fluorescent lamps installed on a platform of a station or the like and equipped with fluorescent lamps as long as about 2 m are provided with fall-off prevention devices for preventing the fluorescent lamps from falling.
As shown in FIG. 5, the drop-off preventing device 10 has arms 10b and 10b projecting in parallel from both ends of a base 10a provided to have substantially the same width as the outer diameter of the fluorescent lamp 12, and the distal ends of both arms. The base 10a is fixed to the reflector 13 of the fluorescent lamp fixture 11 with screws, and the end portion is placed between the arm portions 10b and 10b hanging down from the reflector 13 and the electrode socket 14 is formed. The fluorescent lamp 12 fitted into the fluorescent lamp 12 is press-fitted, and the outer periphery of the fluorescent lamp 12 is sandwiched and supported by both arms.
[0003]
[Problems to be solved by the invention]
Since the conventional fall prevention device 10 is fixed to the lower surface of the reflection plate 13, when attaching the fluorescent lamp 12, an operation of fitting both ends of the fluorescent lamp 12 into the electrode socket 14 and the fluorescent lamp 12 However, there is a problem that the mounting operation has to be performed at the same time, and the mounting operation is troublesome and troublesome.
[0004]
The present invention has been made in view of the above-mentioned problems of the prior art, and is a new type of fluorescent lamp that can securely hold a fluorescent lamp of a fluorescent lamp at a predetermined mounting position, and that can be easily mounted. An object of the present invention is to obtain a structure fall prevention device.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, the fluorescent lamp fall prevention device of the present invention is formed by bending a band-shaped plate material into a substantially U-shaped or V-shaped shape, and both ends thereof are attached to the reflector of the fluorescent lamp and suspended from the reflector. The bent portion side is configured to support the lower periphery of the fluorescent lamp.
[0006]
In the fall-off preventing device having the above-described configuration, the one end portion is provided with a rotatably supported portion, and the other end portion is provided with an outwardly folded portion. Is preferably provided so as to be detachable from an engaged portion provided on the reflection plate.
[0007]
According to this, the bent portion of the fall-off prevention device hung from the reflection plate surrounds the lower side of the fluorescent lamp and supports the fluorescent lamp lower surface, thereby fixing and holding the fluorescent lamp at a predetermined mounting position. it can.
In addition, if one end of the stopper is rotatably provided and the other end is detachably provided with respect to the reflector, the stopper can be rotated and displaced below the reflector. In addition, when the fluorescent lamp is attached to the electrode socket, the fall-off preventing device does not hinder the operation, and the attaching operation of the fluorescent lamp can be performed smoothly.
[0008]
[Embodiment of the invention]
FIG. 1 shows the appearance of a fluorescent lamp equipped with a fall prevention device according to an embodiment of the present invention. As shown in the figure, the fluorescent lamp 1 includes a frame 2 having a lower portion as an opening surface, an electrode socket 3 and a reflection plate 4 mounted in the frame 2, and a fluorescent lamp supported between the electrode sockets 3. The fluorescent lamp 5 is supported by the fall prevention device 6 attached to two peripheral surfaces of the fluorescent lamp 5.
[0009]
More specifically, as shown in FIG. 2, the fall-off preventing device 6 is formed by bending a strip-shaped plate material such as an elongated stainless steel plate into a substantially V-shape, and bending a central portion thereof to have substantially the same diameter as the outer diameter of the fluorescent lamp 5. One end 62 is bent into a cylindrical shape, and the other end 63 is formed to be bent outward.
[0010]
As shown in FIG. 3, the stopper 6 has its cylindrical end 62 engaged with a hole 41 formed in the reflection plate 4, and allows the rotation shaft 43 provided in the hole to pass therethrough. The turning end 63 is rotatably attached to the reflecting plate 4, and a folded end 63 is provided to be freely engageable in a hole 42 also formed in the reflecting plate 4, and the turned end 63 is engaged with the hole 42. In the combined state, the bent portion 61 is hung below the reflection plate 4, and the lower peripheral surface of the fluorescent lamp 5 attached between the electrode sockets 3 is supported by the bent portion 61.
[0011]
Note that the width D between the holes 41 and 42 of the reflection plate 4 is set slightly smaller than the width d between both ends of the fall-prevention device 6, and the folded end 63 is engaged with the hole 42. At this time, the engagement state is maintained by pressing the folded end 63 against the edge of the hole 42 by the elasticity of the fall prevention tool itself.
[0012]
The operation of attaching the fluorescent lamp 5 to the fluorescent lamp fixture 1 equipped with the drop-off preventing device 6 is as follows. Are fitted into the electrode sockets 3, 3, and then the stopper 6 is wrapped around the outer periphery of the fluorescent lamp 5, and the folded end 63 is engaged with the hole 42 to complete the operation.
As described above, when the fluorescent lamp 5 is attached, the fall-off preventing device 6 does not interfere, and after the fluorescent lamp 5 is attached to the electrode sockets 3, 3, the falling-off preventing device 6 may be attached. In comparison, the mounting operation of the fluorescent lamp 5 is simplified, enabling quick and smooth mounting, and the fluorescent lamp 5 is stabilized by the bent portion 61 of the fall-off prevention device 6 wrapped around the lower peripheral surface of the fluorescent lamp 5. [0013]
It should be noted that the illustrated form of the drop prevention device 6 is an example, and the present invention can be configured in various other forms. The falling-off preventing device 6 can be provided in any other suitable form, regardless of the bent shape, as long as the lower portion of the fluorescent lamp 5 can be supported by the bent portion 61 suspended from the reflection plate 4. 4A and 4B show another embodiment. FIG. 4A shows a case where a bent portion 61 is bent, FIGS. 4B and 4C show a case where the whole is bent substantially in a U-shape, and FIG. A bent portion is provided in the bent portion 61. Further, both end portions 62 and 63 of the fall-off preventing device 6 may be detachable from the reflection plate 5.
