The inventive portable telescopic mast (1) consists of telescopic profiles (P) that can move up and down telescopically, flanges (F) located at the end of each profile (P) that prevent said profiles (P) from rotating in an uncontrolled manner around their axis, the motor-reducer group (MR) that provides the movement of the drive rope (TH) and fixing tray (ST) on which the portable telescopic mast (1) is positioned. The motor-reducer group (MR) , is controlled by the control unit (KU) . The motor-reducer group (MR) and the control unit (KU) are positioned on the fixed profile (SP) .

The drive rope (TH) can receive the drive from the motorreducer group (MR) or can be driven manually.

The most important novelty provided by the portable telescopic mast (1) is to provide the profiles (P) by driving the same with a single motor-reducer group (MR) with the rope (H) structure that provides each of the telescopic profiles (P) to be driven by means of the previous profile (P) . Said rope (H) is a polyester rope with a width of 25 mm X thickness of 1.8 mm.

The portable telescopic mast (1) consists of a number of profiles (P) so as to meet the required height with respect to the field of use. There is only one motor-reducer group (MR) in the invention, though the number of profiles (P) forming the invention varies. In this case, only the capacity of the motor-reducer group (MR) , which will provide the drive so as to move said profiles (P) upwardly and downwardly, differs depending on the number of profiles (P) constituting the invention. In other words, a motor-reducer group (MR) that has an appropriate capacity to lift the profiles (P) (the apparatus that is expected to carry the profiles and to be carried by the profiles) , is located in the portable telescopic mast (1) is used.

The portable telescopic mast (1) consists of a fixed profile (SP) that does not move at the bottom and profiles (P) that can move in the upward and downward direction within said fixed profile (SP) . The motor-reducer group (MR) is positioned on the fixed profile (SP) . The drive rope (TH) driven by the motor reducer group (MR) , passes through the flange (F) of the fixed profile (SP) and goes about the bottom portion of the first profile (P) located in the fixed profile (SP) and thus is fixed to the fixing point (SN) located on the flange (F) of the fixed profile (SP) . One end of the drive rope (TH) is fixed to the fixing point (SN) and the other end of the same is connected to the motor-reducer group (MR) . Said drive rope (TH) passes over the pulley located on the flange (F) of the fixed profile (SP) and the pulleys located on the bottom portion of the first profile (P) positioned within the fixed profile (SP) . When the drum (T) connected to the motor-reducer group (MR) wraps the drive rope (TH) , the drive rope (TH) stroke passing under the first profile (P) positioned within the fixed profile (SP) is reduced and thus the first profile (P) advances in the upward direction.

The motor-reducer group (MR) only drives the driving rope (TH) and provides the first profile (P) to move upwardly and downwardly .

The telescopic profile (P) structure such as the second profile (P) in the first profile (P) , the third profile (P) in the second profile (P) , the fourth profile (P) in the third profile (P) , etc. continues in the same manner so as to make the invention to reach the required height. The opening and closing speeds of the telescopic profiles (P) are the same. While the upward and downward movement of the first profile (P) is provided by means of the drive rope (TH) driven by the motor-reducer group (MR) , the upward and downward movement of the second profile (P) located in the first profile (P) is provided by the upward and downward movement of the first profile (P) . Similarly, the upward and downward movement of the third profile (P) in the second profile (P) is provided by the upward and downward movement of the second profile (P) . This operating system is also applicable to the other profiles (P) . In other words, each profile (P) receives its upward and downward movement from the preceding profile (P) in which it is located.

While the upward and downward movement of the first profile (P) is provided by the drive rope (TH) that is driven from the motor-reducer group (MR) , the upward and downward movement of the second profile (P) positioned within the first profile (P) is provided by means of the rope (H) , one end of which is connected to the fixing point (SN) on the flange (F) of the first profile (P) and which is connected to the flange of the fixed profile (SP) in which the first profile (P) is located by passing through the bottom portion of the second profile (P) positioned within the first profile and by exiting from the other part of the flange (F) of the first profile (P) .

While the first profile (P) moves in an upward direction, the part of the rope (H) out of the first profile (P) , one end of which is connected to the flange (F) of the fixed profile (SP) , the other end of which is connected to the flange (F) of the first profile (P) , will elongate and thus, the second profile (P) is enabled to move in an upward direction by decreasing the stroke of the rope (H) passing from the bottom portion of the second profile (P) included in the first profile (P) . While the second profile (P) moves in an upward direction, the part of the rope (H) out of the second profile (P) , one end of which is connected to the flange (F) of the first profile (P) , the other end of which is connected to the flange (F) of the second profile (P) , will elongate and thus, the third profile (P) is enabled to move in an upward direction by decreasing the stroke of the rope (H) passing from the bottom portion of the third profile (P) included in the second profile (P) . Third, fourth, fifth, etc. profiles (P) also work with this operating principle. The most important aspect herein is that the upward and downward movement of the first profile (P) is provided by the drive rope (TH) that is driven from the motor-reducer group (MR) , the upward and downward movement of all telescopic profiles (P) after the first profile (P) is provided from the preceding profile (P) and the rope (H) structure within said profile

(P) •

Said rope (H) configuration that provides the telescopic profiles (P) constituting the main element of the portable telescopic mast (1) to be driven from each other, operates based on the following principle; the rope (H) which provides the upward and downward movement of the other profiles (P) within the first profile (P) , whose one end is connected to the fixing point (SN) on the flange (F) of the preceding profile (P) in which there is the profile (P) that it provides its upward and downward movement and that connects to the flange (F) of the two previous profile in which the previous profile (P) is located by means of passing through the bottom portion of the profile (P) that it moves and by means of exiting from the other side of the flange (F) of the previous profile (P) in which the profile (P) that it moves is located and that is connected to the flange (F) of the two previous profile (P) with the advance of the previous profile (P) in the upward direction; extends with its section outside the previous profile (P) and thus provides said profile (P) to move in an upward manner by decreasing the rope (H) stroke passing through the bottom portion of the profile (P) to be moved and located within the previous profile. Said rope (H) configuration is applicable to all of the telescopic profiles (P) located in the first profile (P) that constitutes the portable telescopic mast (1) .

There are pulleys only at the bottom of the first profile (P) , which is located in the fixed profile (SP) . There are flanges with straight channels under the other telescopic profiles (P) in the first profile (P) . The reason for the lack of pulleys in the profiles (P) other than the first profile (P) included in the fixed profile (SP) is that the ropes (H) do not move at the lower point of the profiles (P) since the rope (H) stroke decreases and increases equally on the right and left sides.

The portable telescopic mast (1) becomes fully open when each profile (P) that constitutes the same is driven from the preceding profile (P) .

Each profile (P) is rotated 90° and mounted inside each other in case the profiles (P) go down and interlock so as not to intersect the rope (H) ends onto each other that are connected to the fixing points (SN) located on the flanges (F) .

The telescopic profile (P) configuration is produced by the pultrusion method as wedged by itself, and the profiles (P) that move telescopically are prevented from rotating in an uncontrolled manner around their axes by the profile wedges (PK) on the profiles (P) and said profiles (P) are fixed on the rotation axis by means of specially designed flanges (F) . Each profile (P) is supported by its internal diameters. All forces that can rotate the system are met at the flanges (F) by means of the wedges and thus the invention gains strength in terms of torsion. The portable telescopic mast (1) has a fixing tray (ST) on which it is positioned. The portable telescopic mast (1) is positioned on the required surface by means of said fixing tray (ST) . The fixing tray (ST) is installed on the required surface by means of the fixing rods (SC) .

The motor-reducer group (MR) and the fixing tray (ST) that make up the portable telescopic mast (1) have a modular structure. Therefore, the invention is easily packaged, easy to transport, and easy to install. The portable telescopic mast (1) can be operated manually without the requirement of a motor since the motor-reducer group (MR) has a modular structure. In other words, the portable telescopic mast (1) can be used both manually and automatically.

As it is shown in Figure 10 in detail, the portable telescopic mast (1) is fixed to the surface where it will be positioned by means of the fixing ropes that are extended/connected to the ground and are driven by manual or electromechanical subsystems from the plates located on the flanges (F) , so as not to be affected from negative environmental conditions. When the height that the portable telescopic mast (1) will reach is taken into consideration, fixing ropes that are extended/connected to the ground are used in an amount that can provide said height.

Otherwise, as shown in detail in Figure 11, the portable telescopic mast (1) can be used with a tripod and can be positioned on the surface that it will be used.

Industrial Applicability of the Invention

The invention may be used in many military and civilian applications that can be integrated into all types of land and sea platforms, at the same time can be assembled in fixed plants and open fields.
