Detailed Description of the Invention:

The components of the invention are basically; the vertical shaft (1), the mounting part (2), the locking hook (3), the horizontal shaft (4), the trailer post (5), the engine (6) and the hinge (7) (Figure- 1, Figure-2, Figure- 3).

The vertical shaft (1) in the product according to the invention consists of two parts. These parts are the first bevel gear (1.1) and the second bevel gear (1.2) (Figure-2, Figure-3).

There is a horizontal shaft (4) associated with the vertical shaft (1) and the vertical shaft (1) at 90 degrees, which Eire mounted on the trailer post (5). The locking hook (3) is provided on the vertical shaft (1) and the horizontal shaft (4). The invention includes the mounting part (2) which provides the bearing of the vertical shaft (1) and the horizontal shaft (4) (Figure-1, Figure-4, Figure-5).

The operation of the invention is as follows. When the button is pressed against the driver, the engine (6) located on trailer post (5) of the semi-trailer operates and makes a pivoting motion. The engine (6) transmits this rotational movement to the engine bevel gear (6.1). The engine bevel gear (6.1) begins to rotate. The first bevel gear (1.1) associated with the engine bevel gear (6.1) rotates together. Since the first bevel gear (1.1) is stationary on the vertical shaft (1), it rotates to the vertical shaft (1). The movement of the vertical shaft (1) also imparts rotation to the second bevel gear (1.2) located at the end. The second bevel gear (1.2) rotating with the vertical shaft (1) transmits this movement to the third bevel gear (4.1). The third bevel gear (4.1) fixed to the end of the horizontal shaft (4) rotates with the horizontal shaft (4). When rotating the vertical shaft (1) and the horizontal shaft (4) nested into the mounting part (2), the locking hooks (3) which are fixed on them rotate in the direction of rotation of the vertical shaft (1) and the horizontal shaft (4). In this way, the locking tab (3.1) is disengaged by the cover (K) and the slot (5.1). Finally, the cover (K) is rotated around the hinge (7) and opens to its opening position (Figure-2, Figure-3, Figure-5). The first alternative embodiment of the invention is based on: the vertical shaft (1), the mounting part (2), the locking hook (3), the horizontal shaft (4), the father of the trailer post (5), the hinge (7) and the holding handle (8) (Figure-6, Figure-7, Figure -8).

The first alternative embodiment of the invention is as follows; the holding handle (8) fixed to the horizontal shaft (4) and / or the vertical shaft (1). When the holding handle (8) is rotated, the rotary movement gives the second bevel gear (1.2) at the end of the vertical shaft (1) to rotate. The second bevel gear (1.2) in the same direction with the vertical shaft (1) transmits this movement to the third bevel gear (4.1). The third bevel gear (4.1) fixed to the end of the horizontal shaft (4) rotates with the horizontal shaft (4). When the vertical shaft (1) nested within the mounting part (2) and the horizontal shaft (4) are rotated, the locking hooks (3) which are fixed on them rotate in the direction of rotation of the vertical shaft (1) and the horizontal shaft (4). In this way, the locking tab (3.1) is disengaged by the cover (K) and the slot (5.1). Finally, the cover (K) is rotated around the hinge (7) and opens to its closing position (Figure-6, Figure-7, Figure-8).

The second alternative embodiment of the invention comprises, but is not limited to; the vertical shaft (1), the mounting part (2), the locking hook (3), the horizontal shaft (4), the trailer post (5), the hinge (7) and the engine (6) (Figure-10, Figure-11, Figure- 12).

The operation of the second alternative embodiment of the invention is as follows; When the button is pressed against the driver, the engine (6) starts to rotate. The horizontal shaft (4) and / or the vertical shaft (1) directly fixed to the engine (6) rotate by taking the rotational movement directly from the engine (6). The third bevel gear

(4.1) on the horizontal shaft (4) rotates the vertical shaft (1) by transmitting this movement to the second bevel gear (1.2). When the vertical shaft (1) nested within the mounting part (2) and the horizontal shaft (4) are rotated, the locking hooks (3) which are fixed on them rotate in the direction of rotation of the vertical shaft (1) and the horizontal shaft (4). In this way, the locking tab (3.1) is disengaged by the cover (K) and the slot (5.1). Finally, the cover (K) is rotated around the hinge (7) to the position which can be opened and closed (Figure-10, Figure-11, Figure-12).
