Abstract

PROBLEM TO BE SOLVED: To facilitate power line connection work by providing an engage- securing member between a pole through which a power line passes and a lamp unit from which a lead comes out, with the engage-securing member having at its fore-end a hook for engaging with the pole and at its middle a terminal block and secured at its tail end to the lamp unit. SOLUTION: To attach a lamp unit 2 to a pole 1, first an engagement hook 9 is made to engage with the brim of a lamp securing portion 6 to temporarily suspend the lamp unit 2. In that state, a power line 4 is secured to an engage- securing member 3 using a lead holder 12, and the fore-end of the line 4 is connected to a terminal block 13 to which a lead 8 of the lamp unit 2 is connected in advance. Next, while releasing the engagement of the engagement hook 9, an attachment portion 7 of the lamp unit 2 is fit to the securing portion 6 of the pole 1 and tightened with a bolt. This makes the connection work between the lead 8 of the lamp unit 2 and the power line 4 of the pole 1 safe and easy so the lamp unit 2 may be attached safely and securely by a single worker.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture having a lamp provided on the top of a pole.

[0002]

2. Description of the Related Art A conventional luminaire of this type is one in which a lamp 71 is directly provided on the top of a pole 70 as shown in FIG. 15 or an arm 72 is provided on the top of the pole 70 as shown in FIG.
There was a lamp 71 provided through the. In any case, power is supplied to the lamp 71 through a power line in the pole 70.

In such a lighting fixture, when the lamp 71 is attached to the top of the pole 70, a power line 73 in the pole 70 and a lead wire 74 drawn from the lamp 71 are connected as shown in FIG. As shown in FIG. 18, the mounting portion 75 of the lamp 71 is fitted into the fixture mounting portion 76 of the pole 70, and is fixed by tightening with the screw 77.

[0004]

However, in this conventional example, the work of connecting the power supply line 73 and the lead wire 74 was not easy because of the work at a high place. In addition, since the lamp 71 cannot be temporarily suspended during construction, two or more people are required to connect the electric wire, and one person must hold the lamp 71 while the electric wire connection work is being performed by one person. I had to do it.

Therefore, when the lamp is attached, the work cannot be performed with simple equipment such as a ladder, a bucket truck or the like is required, and workability is poor and dangerous. Therefore, an object of the present invention is to provide a luminaire in which the work of connecting the power supply line can be easily performed at the time of connecting the electric wire.

[0006]

According to a first aspect of the present invention, there is provided a lighting fixture including a pole having a fixture fixing portion at a top thereof and a power source line inserted therein, and a mounting portion attached to the fixture fixing portion, and being exposed. A lamp having a wire drawn out, a locking claw for locking the top of the pole at the tip, and a terminal block for connecting the power supply line and the lead wire in the middle are provided, and the rear end is attached to the lamp. And a locking device.

According to the lighting device of the first aspect, since the terminal block is provided in the locking tool for locking the pole, the lead wire can be connected to the terminal block in advance, and the power line is fixed to the locking tool of the lamp. The connection work is relatively safe and easy because it is connected to the terminal block. Further, the locking tool can be temporarily suspended or prevented from falling. The luminaire according to claim 2 is the same as in claim 1,
The locking claw is for temporary suspension.

According to the lighting device of the second aspect, in addition to the effect of the first aspect, the power line can be connected to the terminal block while the lamp is temporarily suspended on the pole by the locking tool.
A single operator can mount the lamp safely, easily and reliably. The lighting fixture according to claim 3 has an engagement receiving piece in the center of the top of the pole according to claim 1, and the locking tools are inserted on both sides of the engagement receiving piece so as to face each other inwardly. A pair of springs biased against each other, the locking claw is provided at the tip of the locking tool and is for preventing fall and locks on both sides of the engagement receiving piece, and the terminal block is A temporary suspending tool, which is provided on one side of the locking tool and temporarily suspends the lamp, is provided on the other side of the locking tool.

According to the lighting device of the third aspect, in addition to the effects of the first and second aspects, the light fixture may be detached from the fixture fixing part due to an external load such as vibration or wind when the attachment part is loosened. Even in this case, since the locking claws are hooked on both sides of the engagement receiving piece, it is possible to prevent the lamp from falling and to ensure safety. The lighting fixture according to claim 4 has a step portion on the inner peripheral surface of the top portion of the pole according to claim 1, wherein the locking member is insertable inside the top portion of the pole and biased outwardly from each other. A pair of springs, the locking claws are provided at the tip of the locking tool for temporary suspension and fall prevention to lock and lock the step, and the terminal block is It is provided on one side.

According to the lighting device of the fourth aspect, the same effects as those of the first to third aspects can be obtained.
