Abstract

(57) [Summary] [Purpose] To allow the device body to be separated from the tension wire. [Structure] In a lighting fixture in which a fixture body 2 is rotatably attached to a fixed body 1 so that it can be raised and lowered, the fixture body 1 and the fixture body 2 are connected by a reeler 6 around which a tension wire 5 is wound.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 This invention relates to a lighting fixture.

[0002]

[Prior Art]

 Some conventional lighting fixtures have a one-sided hinge (link) mechanism in which the fixture body of the lighting fixture is rotatably attached to one side of a fixed body attached to the ceiling or the like.

[0003]

[Problems to be solved by the device]

 However, when lowering the main body of the fixture in the conventional lighting fixture, the main body of the fixture suddenly lowers due to its own weight. For this reason, there was a problem that the main body of the equipment hits a person and is injured or the lamp is damaged. Therefore, an object of the present invention is to provide a lighting fixture which prevents the fixture body from dropping suddenly when the fixture body is lowered.

[0004]

[Means for Solving the Problems]

 The luminaire of the present invention is a luminaire in which the luminaire body is mounted on a fixed body so that the luminaire body can be raised and lowered, and the fixed body and the luminaire body are wound with a reeler. It is characterized by being connected.

[0005]

[Action]

 According to the configuration of the present invention, since the reeler around which the tension wire is wound is provided, the instrument body slowly descends. For this reason, even when the instrument body is lowered carelessly when the instrument body descends, no injury or damage to the lamp of the instrument body occurs and the safety is excellent.

【Example】

 A lighting fixture according to an embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 denotes a fixed body installed in an aquarium or the like, which is attached by a one-sided link mechanism 3 so that the main body 2 of the luminaire rotates and moves up and down. Further, the cushioning mechanism 4 is attached so that the instrument body 2 slowly rotates when the instrument body 2 descends.

As shown in FIG. 2, the cushioning mechanism 4 includes a pair of facing reelers 6, 6 having tension wires 5, 5 wound around them and attached to a fixed body 1, and a direction orthogonal to the facing direction of the reeler 6. And a shaft 7 supported by a support 10 between a pair of reelers 6 and 6, and a substantially U-shaped pendulum having both ends attached to the shaft 7 and a pair of holes 8 and 8 in the central portion. 9 and. Then, the tension wires 5 and 5 fed from the pair of reelers 6 and 6 are urged toward the winding side, and the pair of tension wires 5 and 5 are hung on the shaft 7 to be fitted into the pair of holes 8 and 8 of the pendulum 9. It is inserted and fixed to the hook bar 11. Further, the instrument body 2 is provided with a locked portion 12, and the locked portion 12 and the hook bar 11 are locked in a disengaged state. As a result, the instrument body 2 is suspended on the fixed body 1 by the tension wires 5 and 5 (Fig. 3). Although the instrument body 2 is rotatable by the one-sided hinge 13 in the same drawing, the same applies to the one-sided link mechanism 3.

As shown in FIG. 1, the one-sided link mechanism 3 includes a mounting portion 14 to which the instrument body 2 is attached, and a plurality of links whose both ends are rotatably pivoted to the fixed body 1 and the mounting portion 14, respectively. 15 and so on. The instrument main body 2 and the attachment portion 14 are provided with a locking portion 16 and a locked portion 17 which are engaged with and disengageable from each other. Next, the ascending / descending state of the instrument body 2 will be described. First, when the instrument body 2 is lowered when replacing a lamp or a ballast, the instrument body 2 is slowly lowered by the action of the tension wire 5. Therefore, when the instrument body is lowered, no injury or damage to the lamp of the instrument body will occur even if the instrument body is inadvertently separated, which is excellent in safety. Further, when the instrument body 2 is removed, the locking portion 16 and the locked portion 17 of the one-sided link mechanism 3 are unlocked, and the hook rod 11 of the buffer mechanism 4 is removed from the locked portion 12. remove. As a result, the instrument body 2 can be completely separated as shown in FIG. Further, by removing the hook bar 11 from the locked portion 12, the tension wire 5 is rewound onto the reeler 6. At this time, since the pendulum 9 is present even if it is rewound vigorously, the fixed body 1 and the like are not scratched, and the tension wire 5 can be prevented from being entangled.

Further, when the instrument main body 2 is attached to the one-sided link mechanism 3 and further attached to the buffer mechanism 4, the tension wire 5 is pulled down and the hook bar 11 locks the locked portion 12. In this case, the hook bar 11 contacts the pendulum 9 and leaves a lowering allowance, and as shown in FIG. 5, it is easy to pull down the hook bar 11 with the operation rod 18. When the fixture body 2 is attached to the fixed body 1, that is, when the lighting fixture is in use, the tension wire 5 is unwound and the pendulum 9 is housed in the fixed body 1 in a substantially horizontal state. Even in this state, the tension wire 5 is not completely unwound because of the pendulum 9. That is, even when the instrument main body 2 is attached to the fixed body 1, tension is applied to the tension wire 5, the buffer mechanism 4 works constantly, and the locked state of the locking portion 16 and the locked portion 17 is maintained. It

Although the cushioning mechanism 4 is provided in this embodiment, the structure may be such that the fixed body 1 and the instrument body 2 are simply connected by one reeler 6.

[0011]

[Effect of the device]

 According to the luminaire of the present invention, since the reel is provided with the tension wire, the luminaire body descends slowly. Therefore, when the instrument body is lowered, no injury or damage to the lamp of the instrument body will occur even if the instrument body is inadvertently separated, which is excellent in safety.
