Description

[Detailed Description of the Invention] [Structure of the Invention] (Industrial Application Field) The present invention provides an elevating type lighting device in which a motor is removed from the elevating device main body, and the elevating function section and wiring are simplified. Regarding.

(Prior Art) An elevating type lighting device includes a motor inside the device body, and the motor drives a winding device to raise and lower the elevating section via a cable wound around the winding device. I'm trying to let it fall. Such lifting and lowering operations are performed by operating an lifting/lowering selector switch provided on the operation panel. In addition to supplying power for lighting a light source such as a discharge lamp, this illumination device also requires power supply to the winding device. Furthermore, it is also necessary to wire between the operation panel and the winding device.

(Problems to be Solved by the Invention) Therefore, it is inevitable that the wiring for the lighting device becomes troublesome. In particular, since discharge lamps are frequently used and power must be continuously supplied at least while the discharge lamp is lit, it is unavoidable to raise and lower the lifting section. It is only necessary for lamp replacement, maintenance inspection, etc., and the time required to supply power at that time is short, so it is wasteful to have to go to the trouble of wiring for that purpose. In addition, in this type of lighting device, a discharge lamp is generally used as the lamp, and the discharge lamp is configured so that power is supplied through a separate ballast, so the power supply for the winding device and the lamp are It cannot be used in common with the power supply. Furthermore, since the motor is provided in each main body of the apparatus, it is inevitable that the apparatus will be expensive.

[Structure of the invention]

(Means for Solving the Problems) The present invention provides a winding device for winding a rope that suspends an elevating section.
A first gear for driving the winding device is provided, and the first gear is meshed with the second gear in a movable operating body equipped with a motor and a second gear driven by the motor. , the first gear is driven.

Further, the present invention may be arranged such that when the first gear is disengaged from the second gear, the first gear is engaged with the first gear and the first gear is engaged with the second gear.
A stopper is provided to stop the rotation of the gear.

(Function) The power to raise and lower the winding device is supplied from a connector such as an outlet installed on a wall, pillar, etc. via the operating body, so it is not suitable for the lifting type lighting device. It is no longer necessary to perform each wiring for power supply to the elevating section and for elevating and lowering operations separately from the wiring for power supply to the lamp, and the wiring can be simplified. Moreover, there is no need to provide a motor in each device, and therefore manufacturing can be done at low cost.

(Example) An example of the present invention will be described with reference to the drawings. 1 is a lifting device main body, 2 is a cable hanging from the main body, 3 is a winding device for the cable 2, 4 is a lifting part suspended from the main body 1 via the cable 2 so that it can be raised and lowered, and 5 is a winding. This is a first gear connected to the take-up device 3 and used to drive this take-up device. This first gear 5 is driven by a second gear 7 provided on the operating body 6. That is, the operating body 6 has a motor 8, the second gear 7 driven by the motor 8, and a power cord 9, and by meshing the second gear with the first gear 7, the first Gear 5 is driven.

A stopper 10 is provided near the first gear 5, and engages with the first gear 5 when the second gear 7 is disengaged from the first gear 5. The rotation of gear 5 of No. 1 is stopped.

Next, to explain the above embodiment in more detail, the elevating part 4 is a lamp body comprising a reflector 11 and a lamp (not shown) such as an HID lamp inside the reflector 11, and the top part has a pair of lamps. A movable contact 12 is provided. The first gear 5 and stopper 10 are provided within a box 15. The stopper 10 has a through hole 13 for guiding, has a protrusion 17 protruding from the lower surface of a plate 16, and is supported by a pair of compression springs 18. 1st
The gear 5 is provided with a plurality of recesses 19 facing the protrusion 17 into which the protrusion 17 can fit. The first gear 5 and the winding device 3 are connected by a flexible shaft 20, whereby the rotation of the first gear 5 is transmitted to the winding device 3 via the shaft 20.

The operating body 6 consists of a cylindrical body 21, inside which the motor 8 and the second gear 7, a protrusion 22, and a shaft 23 are provided at the tip driven by the motor 8. 24
is a changeover switch, depending on the changeover of stop, rise, and fall,
The motor 8 is rotated forward and reverse, and the second gear 7 is accordingly rotated forward and reverse.

Next, the operation of the above embodiment will be explained. When raising and lowering the elevating section 4, the power cord 9 of the operating body 6 is connected to an outlet provided on the wall. Then, the second gear 7 is brought into mesh with the first gear 5 inside the box 15. This is because the protrusion 22 of the operating body 6 is connected to the guide hole 13 provided in the stopper 10.
This can be done smoothly by fitting the In response to this engagement, the stopper 10 moves upward, and the projection 17 disengages from the first gear 5. In this state, the changeover switch 24 is operated to rotate the second gear 7.

This rotation is transmitted to the winding device 3 via the first gear 5 and the flexible shaft 20, and the winding device 3 is driven to wind up or unwind the cable 2. Along with this, the lifting section 4 rises or falls.

By disengaging the second gear 7 of the operating body 6 from the first gear 5, the spring 18 returns and thereby the protrusion 17 of the stopper 10 engages with the first gear. immediately stops, and thereby the winding device 3 also stops, and the movement of the lifting section 4 is also stopped.

The operating body 6 is commonly used for a large number of elevating lighting devices installed on a ceiling or the like, and the elevating portions 4 of each of them are raised and lowered. This eliminates the need for wiring for supplying power to the lifting motor to the lifting device main body 1 and wiring between the device main body 1 and the operation panel.

Further, it is sufficient to provide one motor in common for all lighting devices, and therefore the cost is reduced.

〔Effect of the invention〕

As described in detail above, the present invention includes a first gear for driving the winding device provided in a winding device that winds up a cable that suspends an elevating section, and a motor and a second gear driven by the motor. By meshing the first gear with the second gear of a movable operating body equipped with a gear and a power cord,
The present invention is characterized in that the first gear is driven, and the present invention is also characterized in that when the first gear is disengaged from the second gear, the first gear The present invention is characterized in that a stopper is provided that engages with and stops the rotation of the first gear. Therefore, the wiring can be simplified, and there is no need to provide a motor on each side of the device, and only one motor needs to be provided in common, resulting in a simple and inexpensive configuration. Furthermore, when the second gear of the operating body is disengaged from the first gear, the lifting/lowering operation of the lifting section immediately stops.
