Description

[Detailed description of the invention] [Technical field] This invention relates to an elevating lighting fixture used in gymnasiums, community halls, stages, etc.

[Background technology]

Conventionally, lighting fixtures installed in gymnasiums and stages have been difficult to maintain, such as replacing lamps, because they are located at high places. Therefore, for ease of maintenance, an elevating lighting fixture has been proposed in which the lighting fixture can be moved up and down.

However, since the irradiation direction of the lamp is fixed, the light distribution is fixed and there is a problem in that it is not possible to obtain an appropriate light distribution according to the purpose of use, such as sports events such as gymnasiums, event contents, etc.

In order to solve this problem, we have proposed a method in which the lamp is vertically rotatably attached to the lifting frame, and the lamp is rotated by a vertical rotation drive device at the rising end of the lifting frame.

However, when the elevating frame is lowered, the lamp is separated from the vertical rotation drive device and becomes freely rotatable.
Your posture becomes stable. As a result, when the elevating frame is raised again, the lighting equipment and elevating frame do not fit smoothly into the non-elevating body that forms the main body, making it impossible to reconnect to the vertical rotation drive device or reconnect the electrical system. There is a problem.

[Purpose of invention]

The purpose of this invention is to provide an elevating type lighting fixture that has a variable irradiation direction, can be used for multiple purposes, is easy to maintain, and can maintain a stable posture when going up and down.

[Disclosure of invention]

The elevating type lighting equipment of this invention includes a non-elevating body, an elevating device that is provided on the non-elevating body and lifts and lowers the elevating frame by suspending it by a hanging rope, and a lamp that is vertically rotatably supported on the elevating frame. a spring member provided between the lifting frame and the lamp to hold the lamp at a predetermined vertical rotation angle; and a spring member provided to the non-lifting body to vertically rotate the lamp at the rising end of the lifting frame. It is equipped with a vertical rotation drive device for moving the vertical rotation drive device.

According to the configuration of this invention, the irradiation direction of the lamp can be changed by the vertical rotation drive device of the non-elevating body. Therefore, by changing the irradiation direction depending on the purpose, an optimal lighting environment can be obtained and multipurpose use can be achieved. In addition, since a lifting device is provided to raise and lower the lamp, the lamp can be lowered to a position on the floor within reach of the worker to replace the lamp, and maintenance of the lamp is easy.

Further, since a spring member is provided between the elevating frame and the lamp to hold the lamp at a predetermined rotation angle, the posture of the lamp is stabilized when going up and down. Therefore, when the elevating frame is raised from below to the rising end, the elevating frame and the lamp are in the proper state relative to the non-elevating object,
Drive transmission by the vertical rotation drive device and electrical system connection can be performed reliably.

The vertical rotation mechanism 13 includes an L-shaped transmitted member 16 attached to the upper part of the lifting frame 8 via a support member 14 so as to be vertically rotatable around a horizontal support shaft 15, and a horizontal piece of this transmitted member 16. and a link rod 29 whose both ends are connected to the supported member 11 of the lamp 1. The vertical piece portion of the transmitted member 16 has a drive transmission piece engaging groove 16a that opens upward and widens on the opening side. The drive transmission piece engagement groove 16a removably engages with the drive transmission piece 18 of the vertical rotation drive device 17 provided on the horizontal rotation block 6. Drive transmission piece 18
is a pin-shaped device protruding from the swing arm 19, and the vertical rotation drive device 17 drives the swing arm 19 to rotate in forward and reverse directions using a motor.

The posture control device 4 is rotatable in two axes by a vertical rotation device consisting of the vertical rotation drive device 17 and the vertical rotation mechanism 13, and a horizontal rotation device (not shown) in the fixed block 5. is configured.

The supported member 11 of the lamp 1 has a horizontally extending piece 11a extending to both sides, and two spring members 20 are hung between the upper part of the lifting frame 8 and both ends of the horizontally extending piece 11a. . The spring member 20 is made of a tension coil spring.

The lamp 1 has a socket 23 and a lamp 24 provided in a lamp main body 22 which opens downward and also serves as a reflector, as shown in FIG. 28 is a power line for the socket 23. The lifting frame 8 has a hanging rope coupling 25 screwed to the center of the upper surface, and guide pins 26, 2 are attached to the hanging rope coupling 25 and the upper surface of the lifting frame 8.
7 is protruding. These guide pins 26, 27
is fitted into a guide hole (not shown) provided in the horizontal rotation block 6 to move the elevating frame 8 to the horizontal rotation block 6.
This is to hold the device in a steady rest position.

Note that power is supplied to the power line 28 of the lamp 1 by the lamp 1.
This is done by a movable contact provided on the lifting frame 8 coming into contact with a fixed contact on the horizontal rotating block 6 at the rising end of the lifting frame. The horizontal rotating block 6 is supplied with power from the fixed block 5 via a power line inserted into a rotating shaft 9 made of a pipe. Horizontal and vertical rotation operations are performed using a remote control device. Further, if necessary, a cover (not shown) is provided to cover the periphery of the lamp 1 when the lamp 1 is located at the rising end.

According to this embodiment, the lamp 1 is always placed at the rising end. At this time, the transmitted member 16 of the vertical rotation mechanism 13 is engaged with the drive transmission piece 16a of the horizontal rotation block 6, and by rotating the arm 19 by the vertical rotation drive device 17, the transmitted member 16 and By swinging the link rod 17, the light fixture 1
can be vertically rotated around the support shaft 12.
In FIG. 2, a indicates a vertically rotatable range of the lamp 1. Further, together with the horizontal rotation block 6, the lamp 1 can be horizontally rotated. Therefore,
The irradiation direction of the lamp 1 can be arbitrarily selected, and as lighting equipment tends to be used for multiple purposes, an optimal light distribution suitable for the purpose can be obtained. Therefore, the scope of use is expanded.

By lowering the light fixture 1 onto the floor using the hanging rope 2,
Maintenance such as replacement of the lamp 24 can be performed safely and easily, and maintenance costs are reduced.

When the lamp 1 is lowered, the vertical rotation mechanism 13 separates from the vertical rotation drive device 17 of the horizontal rotation block 6, but in this embodiment, the transmitted member 16 has a drive transmission piece engagement groove 16a that expands upward. , the lamp 1 engages with the pin-shaped drive transmission piece 18 simply by raising the lamp 1, thereby enabling drive transmission.

Further, since the center of vertical rotation of the lamp 1 is located at the support shaft 12 at the lower end of the lamp 1, the movable range when the lamp 1 is vertically rotated can be reduced.

Since the lamp 1 is tensioned and biased by the two spring members 20, the center of rotation is the lower end of the lamp 1, and the straight downward angle is maintained without wobbling when going up and down. Even if the lamp 1 is tilted when going up or down due to external force or vibration, the urging force of the spring member 20 immediately restores it to a horizontal position. Therefore, when the lamp 1 is raised from below to the rising end, the transmission member 16 and the drive transmission piece 18 can be smoothly engaged. Further, at this time, the fitting between the guide pins 26, 27 and the guide holes of the horizontal rotating block 6 and the connection of the electrical contacts are also performed reliably and smoothly.

In addition, in the embodiment described above, the lamp 1 is rotated horizontally, but the horizontal rotation does not necessarily have to be performed. The vertical rotation drive device 17 and the vertical rotation mechanism 13 are not limited to those of this embodiment, but may have various structures.

[Effect of idea]

In the elevating type lighting fixture of this invention, the irradiation direction of the lamp can be changed by the vertical rotation drive device of the non-elevating body. Therefore, by changing the irradiation direction depending on the purpose, an optimal lighting environment can be obtained and multipurpose use can be achieved. In addition, since a lifting device is provided to raise and lower the lamp, the lamp can be lowered to a position on the floor within reach of the worker to replace the lamp, and maintenance of the lamp is easy.
