DETAILED DESCRIPTION OF THE INVENTION

The fixture assembly subject to the invention is formed of at least a fixed fixture carrier (5) and a fixture (6). An electric socket (12) has been provided at the bottom section of the fixed fixture carrier (5). Furthermore, at least two fixture guide pin slots have been positioned at the same level with the electric socket (12) and a hole has been opened for the lowering rope (9) to be able to pass through the centers of the pin slots.

At least two fixture guide pin slots (15), rope lowering pulleys (14) and an electric motor (13) has been positioned in the inner section of the fixed fixture carrier (5). The extension of the electric socket (12) is located in the inner section of the fixed fixture carrier (5).

At least two, fixture guide rear pins (11) and a fixture electric plug (10) has been positioned at the rear section of the fixture (6) that is located at the bottom section of the fixture assembly subject to the invention. An illuminating section (17), a guide rope container (18), a guide rope (16) that is wound inside the guide rope container (18) and a guide rope container cover (7) has been provided at the front section of the fixture (6). At least two solenoid valves (8) have been placed at the other side of the front section of the fixture (6), at the edge of the rope container (18) such that it is located under the guide rope container cover (7).

The usage of the fixture subject to the invention on the pole (3) has been illustrated on the refuge (2) at the mid section of the road (1) as shown in Figure 1 and Figure 2. When the fixture assembly subject to the invention on the pole (3) is in normal usage; the pins (11) at the rear section of the fixture (6) when the fixture (6) is mounted to the fixture carrier (5), are inserted into the fixture guide pin sockets (12) at the front section of the fixed fixture carrier (5).

At the same time, the electric plug (10) at the rear section of the fixture (6) is plugged into the electric socket (12) located at the front section of the fixed fixture carrier (5).

The state of the fixture (6) subject to the invention that has been lowered to ground level, after it has been separated from the fixed fixture carrier (5), has been illustrated in Figure-5 and Figure-7.

The lowering process of the fixture (6) is enabled by, first of all, the unlatching of the lock housing (4) from the solenoid valve (8) and the descending of the guide rope by gravity after the cover (7) is opened. When the solenoid valve (8) is given energy and is driven, the pin of the solenoid valve (8) frees itself out of the lock housing (4) and the cover (7) of the guide rope container cover (7) is also released and opened. At this moment the rope (16) inside the guide rope container (18) descends down and the operator on the ground can reach the guide rope.

Following this, the operator on the ground drives the electric motor (13) in order to unwind the lowering rope (9) and at this moment, the guide rope (16) is manually pulled down, the electric plug (10) is unplugged from the electric socket (12) and the fixture guide rear pins (11) are released from the fixture guide pin slots (15) and the fixture starts to descend. When the fixture (6) is lowered to a distance that can be safely reached by the operator on the ground, the power of the fixture (6) is cut off. The reason for this is that the fixture (6) is unplugged from the electric socket (12). When the fixture (6) is being lowered down, the operator maintains the control of the guide rope (16), thereby preventing the fixture from swaying due to weather conditions or other factors and also preventing danger. The fixture is pulled back up after the fixture (6) is lowered to ground level and the necessary maintenance-repair procedures are completed. Before the process of being pulled back up, the guide rope (16) is wound and is placed inside the guide rope container (18) and the guide rope container cover is closed and the solenoid valves (8) are driven in the opposite direction and the cover (7) is locked. Following this, the electric motor (13) inside the fixed fixture carrier (5) drives the lowering rope (9) in the opposite direction of the first process, in other words, winds-collects the two lowering ropes (9) by winding them via the electric motor (13) and the pulleys (14) and the fixture (6) is enabled to reach the fixture body (5). The guide rear pins (11) of the fixture (6) that reaches the fixture body (5) is enabled to be fit into the pin slots (15) located inside the fixed fixture carrier (5). At this moment the electric plug (10) that is located at the back of the fixture enters into the electric socket (12) located at the front section of the fixed fixture carrier (5) and electricity is provided to the fixture (6).

The fixture assembly subject to the invention is maintained/repaired safely by means of the above-mentioned processes, without necessitating the usage of a basket crane. The driving process that is carried out by powering the electric motor (13) and the solenoid valves (8) can be carried out via a control panel that has been installed suitably on the pole (3) or by a remote control.
