DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. That is, this disaster prevention lighting fixture includes the fixture main body 1, the emergency lighting device 2, the inspection switch 3, the operation member 4, and the pull member 5. The instrument body 1 is a box having a display panel (56) as shown in FIG. 3, for example, and incorporates all lighting components including a light source and the emergency lighting device 2.

The emergency lighting device 2 is connected to a commercial power supply (not shown) provided in the appliance main body 1 to charge a storage battery (not shown). (Not shown), and a known configuration is applied. The inspection switch 3 is the instrument body 1
Return-type push button 6 that is provided on the main body and protrudes in the horizontal direction.
The contact is connected to the emergency lighting device 2 to check the lighting by the storage battery. In the embodiment, a micro switch is used, and normally, the check switch 3 connects the normally closed contact to the emergency lighting device 2, and when the check switch 3 is pressed, the normally closed contact is opened and the commercial power supply is cut off. The same circuit state as that described above is used to check whether or not the light source is turned on by the storage battery. The inspection switch 3 is directly attached to the printed circuit board 7 of the emergency lighting device 2, and the printed circuit board 7 is attached to the instrument body 1 in a vertical position. Therefore, the push button 6 of the inspection switch 3
Is in the horizontal direction.

The operating member 4 is substantially L-shaped, is mounted above the push button 6, is swingable to press the push button 6, and is biased by a return spring in a direction away from the push button 6. The vertical piece 10 is provided.
Has a horizontal piece 8 connected to the lower end of the first piece. In the embodiment, the vertical piece 10 and the horizontal piece 8 are formed integrally with the operation member 4 using an elastic synthetic resin material having elasticity or a springy metal plate. The vertical piece 10 is formed in a substantially waveform, and its upper end 10a is attached to the upper side of the push button 6 of the inspection switch 3, and is arranged so that the valley 11 of the vertical piece 10 faces the surface of the push button 6. At this time, the vertical piece 10 is normally separated from the push button 6 due to the resin elasticity.
Is in the return state. The horizontal piece 8 has a protrusion 13 for climbing over at a middle position of a sliding range in a direction approaching and separating from the vertical piece 10. Specifically, it is a rectangular flat plate having a long hole 12 formed in a direction in which the horizontal piece 8 approaches and separates from the vertical piece 10, and the protruding portions 13 are provided on both sides of the center of the long hole 12. The protruding portion 13 is provided between a position where the pulling member 5 is not operated and a position where the pulling member 5 is fully pulled on the horizontal piece 8, and is formed, for example, in a conical shape in the embodiment so as to easily get over. ing.

The pulling member 5 pulls the horizontal piece 8 downward and presses the push button 6 with the vertical piece 10. In the embodiment, the upper end has an engaging portion 16 with which the pulling member 5 is slidably engaged with the vertical piece 10 of the horizontal piece 8 in the direction of approaching and separating. The engaging portion 16 of the embodiment is divided at the center of the upper end of the pulling member 5 by 15.
Is formed in an arrow shape so as to be elastically deformable in a narrow width, and a lower end portion (not shown) is formed in a ring shape to catch a finger, for example. The engaging portion 16 is pushed from below through the long hole 12 of the horizontal piece 8 by using the resin elasticity of the split 15, and the engaging portion 16 a of the engaging portion 16 is slidable on both sides of the horizontal piece 8 by restoring the resin elasticity. Is engaged. The pulling member 5 may not only be hung by the operation member 4 but also have a configuration for urging the pulling member 5 upward with a spring or the like.

The operation of the lighting equipment for disaster prevention will be described. That is, when the pull member 5 is pulled downward, the engaging portion 6 pulls the horizontal piece 8 downward as indicated by the arrow a. For this reason,
The horizontal piece 8 rotates downward as indicated by the arrow b. With this rotation, the engaging portion 16 slides along the side edge of the elongated hole 12 as shown by an arrow c, and is locked to the projecting portion 13. Further pulling member 5
Is pulled downward, the upper end portion 10a serving as a mounting portion for the vertical piece 10
With the fulcrum as a fulcrum, the vertical piece 10 rotates while pressing the push button 6 such that the vertical piece 10 is in a vertical posture, so that the horizontal piece 8 is further inclined. When the push button 6 is pressed, the emergency lighting device
The power failure is detected, the storage battery is turned on, and if it is not turned on, it is understood that there is some failure.

When the pulling member 5 is further pulled downward, the vertical piece 10
Pushes the push button 6 to the maximum pushing position to stop the rotation, and the horizontal piece 8 bends so as to further rotate in the vertical posture, whereby the engaging portion 16 rides over the projecting portion 13 and engages. The portion 16 slides abruptly to the end of the slot 12 and locks at that end. This rapid movement is transmitted to the operator and gives a click feeling. At this time, after the operating member 4 presses the push button 6 of the inspection switch 3, the inclination of the horizontal piece 8 of the operating member 4 and the shape of the projecting portion 13 are adjusted so that the engaging portion 18 rides over the projecting portion 13 to generate a click feeling. Is set.

As a result, as compared with the operation amount of the push button 6, the operation amount of the pulling member 5 is increased, and a click feeling by getting over the protrusion 13 is obtained.
According to this embodiment, when the pull member 5 is pulled, the horizontal piece 8
Is pushed downward, and the vertical piece 10 pushes the push button 6 against the return biasing force. At this time, since the horizontal piece 8 is inclined downward, a sufficient amount of pulling operation can be obtained. Therefore, in a simple operation method of operating the push button 6 that operates in the horizontal direction by pulling in the vertical direction, a simple component is used. The structure and operability are good.

The pulling member 5 has at its upper end an engaging portion 16 which slidably engages with the vertical piece 10 of the horizontal piece 8 so as to approach and separate from the vertical piece 10. The engaging portion 16
Has a protruding portion 13 through which the pull member 5
When the horizontal piece 8 is tilted downward by pulling
6 hits the protruding portion 13 and at this time the push button 6 is operated, and when the pulling member 5 is further pulled, the horizontal piece 8 further inclines over the protruding portion 13 and slides on the horizontal piece 8. Therefore, when the push button 6 is operated, a click feeling is obtained in the pulling operation of the pulling member 5, so that the operability is further improved.

Therefore, with a simple component configuration, a click feeling can be transmitted to the operator while pressing the check switch 3, and a sense of security that the operation has been performed reliably can be given. Further, since the operation member 4 elastically bends, the operation amount can be set to be larger than the pressing amount of the push button 6 by pushing the check switch 3, so that the operation feeling is clearly transmitted to the operator. In addition, since the pulling member 5 has a structure that freely moves upward through the horizontal piece 8, even if the erroneously pushes the inspection switch 3 or the pulling member 5 upward during the installation of the tool, the pulling member 5 is not moved. Since it moves upward, the danger that the pulling member 5 is damaged can be avoided.

The shape of the engaging portion 16 is not limited to the above-described embodiment, but may be any shape as long as the engaging portion 16 can be attached to the horizontal piece 8 while being prevented from being detached. Other configurations are possible, such as Although the operating member 4 is biased to return using the elasticity of its own material, the operating member 4 may be biased by using the returning force of the push button 6 or by adding a spring member.

[0020]

According to the lighting apparatus of the first aspect, when the pull member is pulled, the horizontal piece is pulled downward, and the vertical piece pushes the push button against the return biasing force. At this time, since the horizontal piece is tilted downward, a sufficient amount of pull operation can be obtained, and therefore, in a simple operation method of operating the push button that operates in the horizontal direction by pulling in the vertical direction, with a simple component configuration. In addition, the operability is improved.

According to the lighting apparatus of the present invention, when the pulling member is pulled and the horizontal piece is tilted downward, the engaging portion of the pulling member hits the projecting portion, and the push button is operated at this time. The horizontal piece slides on the horizontal piece further over the inclined protrusion. Therefore, when operating the push button, a click feeling is obtained in the pulling operation of the pulling member, so that the operability is further improved.
