DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a spotlight used for stage lighting and the like.

[0002]

2. Description of the Related Art A lens is provided in a front opening of a main body, a lamp and a reflecting mirror are provided therein, and a lid is provided in a rear opening of the main body. There are known spotlights for convenience.

[0003]

However, attention has been paid to the fact that the lens side is often used obliquely downward, so that the lid side faces obliquely upward, and lamp replacement is inconvenient. Should be. In other words, if the lamp is to be replaced, the set position of the spotlight must be set to the horizontal position or the cover side diagonally downward, and then the cover must be opened, and then performed.
The inconvenience of having to turn on the lamp after lamp replacement and to set the position of the spotlight again is remarkable. The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a spotlight that can easily replace a lamp. Another object of the present invention is to provide a spotlight that does not inadvertently cause damage to the lamp or that does not inadvertently change the posture of the spotlight.

SUMMARY OF THE INVENTION In summary, the present invention comprises a main body provided with a lens at a front opening, a lid positioned at a lower opening of the main body and provided with a lamp and a reflecting mirror on the inner surface, and the lid is provided. The bodies are frictionally pivoted spotlights at their front ends so that they can be opened and closed with respect to said body.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention will be described based on matters unique to the embodiment. Therefore, the technical scope of the present invention should be determined based on the matters stated in the claims and matters substantially equivalent to the matters.

The illustrated embodiment comprises a main body 2 provided with a lens 1 in a front opening, and a lid 5 provided in a lower opening of the main body 2 and provided with a lamp 3 and a reflecting mirror 4 on the inner surface. The bodies 5 are spotlights which are axially supported at their front ends by friction so as to be openable and closable with respect to said body 2. The shaft support portion is fixed to the shaft 6 fixed to the body 2 (or the cover 5 side) and the cover 5 (or the body 2 side) and wound around the shaft 6. A friction plate 7 is provided. One end of the shaft 6 is formed in a tapered shape with a side portion chipped, such as a half-moon shape, and one end of the shaft 6 is fixed to a body support plate 8 (or lid 5 side). In the case of the lid 5 side, a shaft support plate 1 described later
The shaft 6 is formed into a half-moon-shaped hole 9 which is adapted to the shape of one end of the shaft 6, and a nut 10 is screwed to one end of the shaft 6. In addition, the shape of one end of the shaft 6 may be a shape in which both sides are missing, and in this case, the hole 9 is suitably a substantially rectangular hole.

More specifically, the shaft support plate 8 has a substantially U-shaped cross section, and its main surface is fixed to the front end of the lower surface of the main body 2 with screws or the like. A hole 9 having a half-moon shape or the like is formed, and a round hole 11 is formed in the other bent portion. A shaft support plate 12 having a substantially U-shaped cross section is fixed to the front end of the lid 5 with screws or the like, and a connecting plate 13 bridged by welding or the like is fixed between the bent portions on both sides, and is preferably a spring. Both sides of the friction plate 7 provided with the property have screws 1
4 and the like. The shaft 6 is inserted from the round hole 11 of the shaft support plate 8, the hole 15 of one bent portion of the shaft support plate 12, the inside of the friction plate 7, the hole 16 of the other bent portion of the shaft support plate 12, and The nut 6 is passed through a hole 9 having a half-moon shape or the like, and a nut 10 is screwed to one end of the shaft 6 via a washer 17. At this time, by tightening the nut 10, the tapered base portion (which is wider than the tip) of the shaft 6 bites into the inner edge of the hole 9, and the shaft 6 is extremely strongly non-rotatably supported. The degree of friction between the friction plate 7 and the shaft 6 can be adjusted by the degree of tightening of the screw 14. In this way, the lid 5 is axially supported by friction at its front end so that it can be opened and closed with respect to the main body 2.

On the other hand, the rear end of the lid 5 and the rear end of the main body 2 have a detachable mechanism. For example, a locking device 19 which is locked by a locking portion 18 at the rear end of the main body 2 is provided. The cover 5 and the main body 2 are provided at the rear end of the cover 5 and provided with an operation section 20 that can be operated to lock / unlock the locking section 18 by rotating the locking tool 19. It can be opened and closed using the shaft support as a rotation axis. The lamp 3 is supported by a support 22 via a socket 21, and the reflector 4 is also supported by the support 22. The support base 22 is supported by a shaft bar 23 having a spiral groove bridged in front and back of the lid 5, and the support base 22 slides back and forth by rotating the operation unit 24 at the rear end of the shaft bar 23. The size of the diameter of the adjusted and projected light spot can be adjusted. Although the main body 2 is supported by a baton or the like (not shown) via a substantially inverted U-shaped support 25, the lens 1 is often used with the lens 1 side obliquely downward as shown in FIG.

When the lamp 3 is to be replaced, it is preferable to rotate the operation unit 20 in the state shown in FIG. However, even if it is opened, the lid 5 is
, The lid 5 does not suddenly pivot down. Usually, the degree of the friction is adjusted to the extent that the cover 5 moves for the first time by manual operation, and the lamp 3 is replaced after the cover 5 is opened by manual operation. Further, since the rapid rotation and lowering of the lid 5 is prevented, the lamp 3 is not damaged by an impact. In addition, since there is no impact due to the rapid rotation and fall of the lid 5, a spotlight in which the position of the spotlight does not change carelessly can be provided, and the need to readjust the position of the spotlight is reduced.
