Description

  The present invention relates to a projector in which an illuminating device is mounted on a support column installed on a carriage.

  There are various types of floodlights that use an engine-driven generator (hereinafter referred to as a “generator”) as a power supply as an illumination device for outdoor road construction and construction sites outdoors. Since the conventional projector mainly aims to perform spot-like illumination, a lamp having a substantially frustum cylinder shape in which a lamp is housed is used.

On the other hand, in recent years, soft and planar illumination has been demanded from the viewpoint of preventing light pollution and preventing dazzling of passers-by, and various forms of lighting devices and lamps have been developed. The projector also requires similar illumination. For example, the projector T ′ shown in FIG. 7 uses a thin circular lamp.
The floodlight T ′ includes a dolly 110 on which a generator 112 and the like are mounted and wheels 111, a telescopic column 120 attached to the dolly 110, and an upper end of the column 120 via a joint 140. And an illumination unit 130 attached thereto.

The illuminating unit 130 is formed of a bowl-shaped and thin reflector whose front surface (light projecting surface) 132 is closed with glass, and a socket housing portion that protrudes in the lateral direction of the reflector and has a socket inside. The lamp 131 has a cylindrical lamp arranged in parallel to the glass on the front surface of the reflector in the lamp 131, and the joint 140 is arranged so that the rotation axis of the lamp 131 is parallel to the lamp optical axis. It is attached.
The joint portion 140 is pivotable about a longitudinal axis at both ends of the lateral arm 141 mounted on the upper end of the column portion 120 so as to be pivotable in the horizontal direction. An arm joint 143 attached to the arm arm 143 and attached to the arm joint 143 in a direction perpendicular to the longitudinal axis of the transverse arm 141 and perpendicular to the longitudinal axis of the transverse arm 141 A vertical arm 142 is mounted so as to be rotatable about an axis, and the lamp 131 has an axis perpendicular to the longitudinal axis of the vertical arm 142 at the end of the vertical arm 142. It is mounted so as to be rotatable around the center (see Patent Document 1).
JP-A-11-7827 ([0011]-[0022], FIGS. 1-8)

However, the projector T ′ has a problem in that a wide irradiation range cannot be secured because the lamps 131 cannot be independently rotated in the horizontal direction.
Further, in the projector T ′, the lamps 131 attached to the vertical arms 142 can be stored so that the light projecting surfaces thereof face each other, but a large gap is generated between the lamps 131. At times, there is a problem that the glass of the light projecting surface 132 of the lamp 131 may be damaged by flying objects such as stone jumping.

  The present invention has been made to solve the above-described problems, and it is possible to ensure a wide illumination range and to reliably protect the light emitting surface during storage. The purpose is to provide a projector.

As described above, the plurality of second support members to which the intermediate portions are attached and both end portions of each of the second support members are rotatable in the horizontal direction and rotatable in the vertical direction. A pair of the lamps attached to the second support members when not in use. , Can be stored with each light emitting surface facing each other It is characterized by being configured such that.

  Further, in the projector, the lamp includes a reflector having a box shape having an opening serving as a light projecting surface, a closing member that closes the opening, and an illuminator provided inside the reflector. When the lamp is not in use, the pair of lamps can be stored compactly in a state in which no gap is generated between the light projecting surfaces and facing each other. In addition to being able to be accommodated, it is possible to prevent the obstruction member of the lamp and the illuminating body from being damaged by flying objects such as stone jumps during transportation.

Here, as long as the blocking member is a material that can transmit the light of the illuminating body and does not deform or deteriorate due to heat generation of the illuminating body, the material is not limited, but weather resistance and safety From this point, it is desirable to use tempered glass. In some cases, the light projecting surface remains open without using the closing member.
In addition, “in a state where there is no gap on each light projecting surface” does not mean that there is no gap between the pair of lamps, but that a slight gap is allowed. It is.

  According to the present invention, each lamp having a light projecting surface formed in a rectangular shape can be arranged at a desired position by rotating independently in the horizontal direction, so that a wide irradiation range is ensured. be able to. In addition, when not in use, the light-projecting surfaces are stored facing each other so that there is no gap, thereby preventing the obstruction member of the lamp and the illuminating body from being damaged by flying objects such as jumping during transportation.

A rear surface portion of the lamp 31 is attached to both ends of one second support member 42 so as to be rotatable. The lamps 31 installed at the ends in the same direction of the respective second support members 42 are each in a normal state (the state where there is no rotation at the third fulcrum 47 and the second support member 42 and the arm 44 form a right angle). The rear surface portions are attached so as to be oriented inward (second support member 42 side). Then, by appropriately determining the length of the second support member 42 and the height of the lamp 31, when not in use, the front ends of the pair of lamps 31 attached to the second support member 42 (side surfaces facing the rear surface portion). , The same applies hereinafter) is rotated 90 degrees downward so that the respective light projecting surfaces 32 face each other with almost no gap (see FIG. 5).
Each of the lamps 31 thus configured has four lamps 31, 31,... That can be rotated integrally over 360 degrees around the first fulcrum 45 of the first support member 41. 2 The position of each lamp 31 can be changed within a range of 45 degrees around the third fulcrum 47 of the support member 42.

[Action and effect]
As shown in FIG. 6, the projector T according to the present invention turns the first movable column 25 and the second movable column 27 after rotating the direction of each lamp 31 to a desired position according to the purpose of use. By irradiating at a predetermined height, the irradiation range can be changed in various ranges.

For example, in a plan view, each lamp 31 is positioned symmetrically about the first fulcrum 45 of the first support member 41, and the light projecting surface 32 of each lamp 31 is horizontal with respect to the installation surface. In this case, the lower part can be irradiated evenly (FIG. 6A).
Further, each lamp 31 is rotated upward about the second fulcrum 46 so that the tip of the light projecting surface 32 is inclined upward (FIG. 6B), or each lamp 31 is moved to the third fulcrum 47. By rotating in the horizontal direction around the center, the irradiation range can be expanded (FIG. 3).

  Further, one lamp 31 in the second support member 42 is rotated obliquely upward at the tip of the light projecting surface 32 around the second fulcrum 46, and the other lamp 31 is moved to the second fulcrum 46. By rotating the front end of the light projecting surface 32 obliquely downward about the center, an area on substantially one side of the carriage 10 can be set as an irradiation range (FIG. 6C). In this case, since the mutual lamps 31 are arranged by the second support member 42 at positions symmetrical with respect to the first support member 41, the mutual lamps 31 and the telescopic struts 20 become shadows. Irradiation can be performed reliably.

On the other hand, after use, the first movable column 25 and the second movable column 27 are lowered to the lowermost position, and the first fulcrum 45 and the second fulcrum 45 of the first support member 41 are arranged so that four lamps 31 are arranged in parallel. The support member 42 is rotated in the horizontal direction around the third fulcrum 47. Then, both the lamps 31 in each second support member 42 are rotated 90 degrees obliquely downward from the tip of the light projecting surface 32 around the second fulcrum 46 so that no gap is generated in each light projecting surface 32. In this way, they are stored so as to face each other (see FIG. 5).
By doing so, it is possible to store the compactly, and it is possible to prevent the blocking member 34 and the lamp 35 of the lamp 31 from being damaged by flying objects such as a stone jump during transportation.

Furthermore, according to the projector T of the present invention, each lamp 31 can be rotated to a desired position in the horizontal direction, so that the adjacent lamp 31 and the mounting base 43 are obstructed when the lamp 35 is replaced. Since there is nothing, it can be performed easily.
Moreover, according to the projector T of this invention, since the rotation mechanism of each lamp 31 can be made into a simple structure, manufacturing cost can be reduced.

Heretofore, an example of a preferred embodiment has been described for the present invention. However, the present invention is not limited to the above-described embodiment, and the design of each of the above-described components can be appropriately changed without departing from the spirit of the present invention.
In particular, the number of the second support members may be two or more, and the lamps can be provided in even numbers of four or more according to the number of the second support members.
