Further, from this state, the stopper piece 12 is rotated toward the locking shaft 14, the locking shaft 14 is inserted into the locking groove 12a, and the stopper piece 12 is locked at a position in front of the mounting hole 10e.
The locking member 11 is sandwiched together with the outer locking surface 10c to prevent the locking member 11 from falling off.

In this state, the generator 5 is firmly fixed to the mounting surface 1 'and integrated with the carriage 1. Therefore, the projector A mounted with the generator 5 is lifted by a crane, for example, by hooking a hook at the wire tip on the hook ring 5d, and the height exceeding the extension limit of the telescopic strut 2 and the installation of the bogie 1 are improper. The use of the floodlight A on the stable site becomes possible. In such a state of use, since the generator 5 is firmly fixed to the carriage 1 by the locking mechanism, the work can be performed safely without fear of a fall accident or the like.

When the generator 5 is used away from the carriage 1, for example, the stopper piece 12 is turned to the side opposite to the locking shaft 14 to retract from the front of the mounting hole 10e, and then the locking member is used. When the lower edge bent portion 11b is pulled out from the mounting hole 10e, the holding of the generator 5 by the locking member 11 is released. In this state, the generator 5 is lifted by several persons and lowered from the carriage 1.

As described above, the fixing of the generator 5 to the carriage 1 and the release thereof can be performed without using any screw tool or the like without using the locking member 11.
The lower edge bent portion 11b can be inserted into and removed from the mounting hole 10e, and the stopper piece 12 can be rotated between the holding position and the retracted position.

It should be noted that the locking frame 10 is not limited to the above-described one, and may have a configuration other than that shown. For example, although not shown, instead of the above-described reinforcing plate, a rail having a substantially L-shaped cross section is fixed along the front edge portion and the rear edge portion of the generator mounting surface 1 ′, and the upright surfaces on both sides in the longitudinal direction of the rail are fixed. The front and rear locking surfaces 10a, 10b are formed in a rectangular frame shape in plan view, and the middle part of the left and right rails 10d is deleted to generate a substantially L-shaped frame material in plan view. For example, a configuration in which the generator 5 is mounted on a square portion of the machine mounting surface 1 ′ can be exemplified. In short, the front and rear locking surfaces 10 a, which prevent the generator 5 mounted on the bogie 1 from moving in the front-rear direction. Any structure may be used as long as it has an outer locking surface 10c for preventing the generator 5 from moving in the left-right direction.

Further, the locking means of the stopper piece 12 is not limited to the above-described one.
e, rails are provided on both the left and right sides, and a stopper piece 12 separated from the locking frame 10 is inserted from above into the two rails and locked at the above-described holding position, while being pulled out from between the two rails. It may be moved to the evacuation position. In short, it is locked at a position in front of the mounting hole 10e, and a holding position for holding the locking member 11 together with the outer locking surface 10c, and withdrawing from the front of the mounting hole 10e. Various known structures can be adopted as long as the locking member 11 can be freely moved to and from a retracted position where the attachment and detachment of the locking member 11 is free.

Further, the floodlight provided with the above-mentioned locking mechanism is not limited to the above-mentioned one, but may be a type having two or more lights, a type having two or four or more telescopic columns, a telescopic column. It can be mounted on floodlights of various structures, such as a type that controls the steering of the bogie by rotating the operating shaft that rises behind the type, and a type that allows the telescopic strut to be separable from the bogie. Nor

As described above, the floodlight of the present invention has the following features.
A locking mechanism for a wheeled generator mounted on the bogie, the locking mechanism being provided on a top surface of the bogie, and a locking frame for regulating movement of the generator in a front-rear direction and a left-right direction; A locking member detachably attached to the frame, for restricting the vertical movement of the generator, and a stopper piece for preventing the locking member from falling off, the locking frame, the locking member, The generator mounted on the truck can be firmly fixed by the locking action and the holding action by the stopper pieces. Therefore, by hoisting the generator with a crane, it can be used at a height exceeding the extension limit of the telescopic strut, or can be used at a site where the installation of the bogie is unstable, and there is a risk of a fall accident and the like. No safe work could be achieved.

Further, since the locking member is attached to the locking frame without fear of falling off by the stopper piece at the holding position, the above-mentioned safety is reliably maintained while the stopper piece is moved to the retracted position. In the state, the lower edge bent part can be attached to and detached from the locking frame by simple work just by inserting and removing it from the mounting hole, and with the locking member removed from the locking frame, loading and unloading of the generator It can be done freely.

Therefore, the generator with wheels mounted on the trolley can be securely fixed by a simple operation without using a screw tool or the like, can be easily removed, and can be securely fixed to the trolley. Because it can be very safe.
