Description of the Related Art Conventionally, as a retractable suspension device of this kind, as disclosed in, for example, Japanese Utility Model Publication No. 43-17390, when a telescopic leg is extended, a mainspring is wound and the telescopic leg is contracted and pushed. There are known stick hangers that utilize the restoring force of a mainspring and sometimes extend and retract the telescopic leg to an arbitrary position to stop the expansion and contraction at that position. This stick hanger is connected by a wire cord to a central shaft with one end of the mainspring spring fixed, a car with the other end of the mainspring spring fixed and rotating around the central shaft, and a grooved wheel integrated with this car. Extendable legs, two grooved wheels and two ratchet wheels fixed to the center shaft, two locking claws respectively engaged with these ratchet wheels, and these locking claws engaged with or disengaged from each ratchet wheel. It is equipped with a push button and a handle that can be pushed.When the push button is pushed, the locking claw is removed from the ratchet wheel, the mainspring is wound when the telescopic leg is extended downward, and the push button is stopped when it is extended to an arbitrary length. When the locking claws are locked to the ratchet wheel and the telescopic legs are stored, the telescopic legs are contracted by the restoring force of the mainspring if the innermost telescopic legs are pushed up and pushed up.

くなると共に重量がかさむ等の問題があった。By the way, according to the above-described conventional suspension device, the expansion and contraction leg extended to an arbitrary length is locked by controlling the rotation of the mainspring. Moreover, since the push button, which is the operation unit for controlling the push button, is provided near the center axis of rotation of the mainspring that is located near the ceiling of the studio during installation, it is difficult to operate the push button in the installed state. There's a problem. In addition, other conventional suspension devices do not have a lock mechanism that fixes the stretched state of the telescopic legs (fixes the winding state of the mainspring spring), and when the telescopic legs are stretched, the load on the luminaire will disappear. Since the telescopic leg will contract vigorously due to the restoring force of the mainspring, when extending the telescopic leg and replacing the lighting equipment suspended at its lower end, you must work while holding down the telescopic leg so that it does not contract. There was a problem that the replacement work of the lighting fixture was troublesome. Further, in the conventional suspension device, each leg is provided with a key or a key groove in order to prevent the extension leg from rotating when adjusting the angle of the lighting fixture, which increases the manufacturing cost of the extension leg and adds weight. There was a problem such as.

The object of the present invention is that the stretched state of the telescopic leg can be fixed in a releasable manner, and the fixed state can be fixed. It is an object of the present invention to provide a retractable suspension device for a lighting fixture, which can easily perform an operation for performing the operation even in an installed state. Another object of the present invention is to prevent rotation of the telescopic legs when adjusting the angle of the lighting fixture with a simple structure.

Then, the spring force of the constant force spring 1 is adjusted appropriately, and in that state, the hanger 40 hangs the hanging bar B and sets it in a television studio or the like. Then, in the unlocked state in which the lock shoe 23 is separated from the brake shoe 20, the telescopic leg 2 is extended by holding the cable receiver 6 and lowering it, and the height of the lighting fixture C is arbitrarily adjusted and set. . When the telescopic leg 2 is contracted, the restoring force of the constant load spring 1 is exerted by slightly pushing up the lighting fixture C, and the telescopic leg 2 contracts as the withdrawal portion 9b is rewound, so that the lighting fixture C is in the desired position. Rise to height. When replacing the luminaire C, the drawer 9 is operated by operating the lock mechanism 4.
B is sandwiched between the brake shoe 20 and the lock shoe 23, the restoration is locked, and the replacement work is performed. In this example,
Since the operating lever 25 of the lock mechanism 4 is a rod, the difference between the locked position and the unlocked position by the lock mechanism 4 is
There is an advantage that it can be distinguished at a glance by the angle of the operation lever 25.
