Description

  The present invention relates to a projector that is an illuminating device used outdoors such as road works, and particularly relates to a projector using an illuminating device in which a balloon incorporating a light emitter is inflated with air.

Conventionally, as a floodlight used for night lighting of this kind of road construction and sports facilities, a telescopic support column is erected on a dolly equipped with a generator, and the light from the light bulb is reflected on the upper end of the telescopic support column. Is equipped with a lighting device that projects light forward, and includes a balloon, air supply means for inflating the balloon, and a light bulb built in the balloon (for example, Patent Document 1).
JP 2003-36709 A

  However, even in the projector described above, the light provided by the light bulb incorporated in the balloon is sufficient to alert the pedestrian or the driver of the passing vehicle, but the light is transmitted by passing through the balloon. Therefore, it cannot be said that the light is sufficient for the construction worker to work at night, and it is necessary to install a projector with a light separately for the construction worker. However, in order to install multiple projectors, of course, it requires an additional installation location and storage location, which not only obstructs the work, but also narrows the path for pedestrians and traffic vehicles, and also requires movement. There was concern that it would increase labor and cause accidents. In addition, since each has a generator, there was a concern that noise would be increased particularly during construction in residential areas.

  In addition, the lighting device 3 can be adjusted by extending / contracting the length of the support column 4, and the light 14 can be maintained at an appropriate height by adjusting the length of the second expansion / contraction support member 25. Moreover, since the light 14 can turn the light 14 in the vertical direction in the gripping member 27, the directions of the two lights 14 can be adjusted respectively, and light can be supplied only to necessary places. The gripping member 27 may be rotatably provided on the second expansion / contraction support member 25. By doing so, the light 14 can be rotated about the vertical axis, so the degree of freedom in determining the direction of the light 14 can be increased, and the usability can be improved.

  Next, the effect | action in above-described embodiment is demonstrated.

  When a start switch (not shown) of the power supply device 5 is turned on, the engine is started and a generator connected to the output shaft stores power, and a battery (not shown) built in the generator is charged. When a power supply switch (not shown) is turned on, electric power is supplied from the battery to the lighting device 3 and / or the light 14, and air is supplied into the balloon 2 by the driving unit built in the lighting device 3. 2 is inflated, and the illuminant is turned on at the same time.

  On the other hand, the illuminating device 3 pulls out the inner cylinder 21a from the outer cylinder 21b, adjusts the length of the first telescopic support member 21, is fixed by a stopper, and protrudes rearward of the carriage 5. Furthermore, a fixing means (not shown) provided on the first telescopic support member 21 can be released, and the lighting device 3 can be moved up and down or rotated to be fixed at a desired position. The light 14 is pulled out from the outer tube 24b by adjusting the length of the arm member 24 and fixed by a stopper, and is projected forward of the carriage 5. Further, the light is drawn out from the outer tube 25b to the second position. The length of the telescopic support member 25 is adjusted and fixed by a stopper, and is pushed up above the carriage 5. Further, the fixing means (not shown) provided on the arm member can be released, and the light can be moved up and down or rotated to be fixed at a desired position. Next, when the lifting handle 12 is rotated clockwise in a side view and the wire 13 is supplied to the lifting device, the lifting device can extend and the column 4 can be extended. When the column 4 is extended to a desired height, the column 4 is fixed by a stopper (not shown). At this time, the direction of the light 14 can be appropriately adjusted in the vertical direction and the horizontal direction.

  In this way, in one power supply device 5, light can be supplied to a wide range by the lighting device 3 provided with the balloon 2, and at the same time, the location and direction of light irradiation can be determined by the two lights 14 provided on the front side. It can be specified to provide more efficient and sufficiently bright light.

  Next, the case where the said projector 1 is stored is demonstrated with reference to FIG. 3, FIG. FIG. 3 is a side view illustrating the projector, and is a diagram illustrating a state in which the illumination device and the light are rotated. FIG. 4 is a side view showing the projector, and shows a state in which the lighting device and the light are stored by contracting the telescopic support member.

  The power supply button is turned off, the light emitter is turned off, and the drive unit is stopped. Next, the lifting handle 12 is rotated counterclockwise in a side view and the wire 13 is wound up to contract the support column 4 to an initial state, and in that state, the length is fixed by a stopper. Further, the lighting device 3 and the light 14 can be stored on the front side with the support shaft portion 26 as a center. In other words, until the fixing member is released and the arm member 24 is limited to a stopper (not shown) with the first expansion / contraction support member 21 and the second expansion / contraction support member 25 centered on the support shaft portion 26 (approximately 90 °). The lighting device 3 and the light 14 can be stored on the front side by rotating in the vertical direction. By doing in this way, since the said illuminating device 3 and the said light 14 can be stored on the plane of the trolley | bogie 8, the movement by the trolley | bogie 8 can be made easy and a storage place can be made small. Further, by contracting the first expansion / contraction support member 21, the arm member 24 and the second expansion / contraction support member 25, that is, fixing by the stopper is released, the inner cylinders 21a, 24a and 25a are connected to the outer cylinder 21b. , 24b, 25b, the entire lengths of the first telescopic support member 21, the arm member 24, and the second telescopic support member 25 are contracted and can be stored more compactly. At this time, by folding the balloon 2, the first telescopic support member 21 can be contracted to the shortest and can be stored more compactly in the upper part.
