DETAILED DESCRIPTION OF THE INVENTION

The bicycle fixing mechanism (A), which is adapted to the vehicle roof containing the locking unit (600) that transmits motion to the said clutch mechanism (100) through the tension element (200) and enables the bicycle (1 ) to be fixed, comprising the gripping mechanism (100), which secures the body of the bicycle (1 ) through the movable jaw (120) and fixed jaw (110), is illustrated in Figure-1 .

The fixing mechanism (A) comprises the moving jaw (120), which fixes the bicycle (1 ) body with two different axial rotations, with the second rotation axis (E) and the first rotation axis (E1 ), the upper jaw bed (250), where the said moving jaw (120) is fixed at one end by means of the second rotation axis (E) axis, the moving jaw (120), which is connected by the first rotation axis (E1 ) at the other end of the said upper jaw bed (250), and the tension element (200) and the manual movement applied, a driving element (150) that applies constant forces on the first return axis (E1 ), while the locking unit (600) of the said locking unit (621 ) is open, a latch that wasted the tension force given by the tensioning element (530) to the tension element (200) and that provides the opening of the grip jaw (534) and conical surfaces (340), which have at least one outer hive (310) and internal hive (320) having a narrowing cross-section, which allows the duct (160) part of the gripping mechanism (100) to be fixed to the pipe (301 ) and a compression unit (300) with a connector (330), which squeezes the said pipe (301 ) by inflating it from the inside. It comprises a partial gap (252) in which the said tension wire (200) passes through the back of the movable jaw (120) and prevents the movable jaw (120) from moving intoxicated during the opening and closing of the gripping mechanism (100), and the lock tongue (621) and the nail spring (623) of the threaded locking part, which stretches the said tensioning element (530) clockwise by turning it clockwise and wrapping the tension wire (200) around itself and locking onto the gear tabs and preventing the tensioning element (530) from turning in the opposite direction.

Moreover, it includes a locking element (620) with a locking tongue (621 ) that prevents the anti-clockwise movement of the tensioning element (530), that is, the release of the tension element (200), and a lock trigger element (610) that blocks the movement of the latch (534).

On the other hand, it comprises the connector (330) and a locking part (350) for the connection of the compression unit (300) to the conical surface, and in the place where it is connected to the gripping mechanism (100), the exterior hive (310), which prevents the rotation and transmission movement of the mentioned pipe (301 ), prevents the rotation movement with the protrusions on it and preventing the translation movement with its conical form and the curtains on the outer surface (351 ) moving in the direction of D5 (340) without rotating around its axis (352).

The said upper jaw bed (250) has the plug (230) with retaining slot (232) for the knob (240) part, which is practically mounted by screwless insertion technique, on which flexible flanks (231 ) are formed, the said tensioning element (200) is steel wire, and the knob part (240) is used to spread the tension load on the tensioner element (200) and to ensure the retention in the slot formed in the plug (230) of the tension element (200), when placed in the plug slot (251 ) at the top of the upper jaw rest (250) and the plug slot (251) on the said upper jaw rest (250), which allows the plug (230) to be fixed by screwless insertion technique; comprises nails (234) that prevent the plug (230) from exiting the socket.

In Figure-2, the fixed jaw (110) gripping the frame of the bicycle from the lower surface is fixed, while the gripping mechanism (100) on the upper surface consists of two parts: the movable jaw (120) and the upper jaw bed (250). This jaw structure creates a catching mouth (150.1 ) that can be opened and closed to hold the cadre of the bicycle while it is placed on the carrier. The jaw structure can be opened and closed enough to capture an elliptical or circular form bicycle frame with a maximum height of 120 mm and a maximum width of 80 mm (K1 : 120mm-70mm - K2: 100mm-80mm - K3: 020mm), with a minimum diameter of up to 20 mm. In addition, the movable jaw (120) can also be moved independently (in the D2 direction) so that the distance of the capturing mouth (150.1) can be opened a little more depending on the need. Therefore, it makes it easier for elliptical-shaped or large- scale cadres to enter and exit the capturing mouth (150.1 ).

In Figure-3, there is a plug (230) that is inserted into the plug socket (251 ) positioned on the top of the upper jaw bed (250). The knob piece (240), which is the head part of the tension wire (200), passes into the cylindrical surface (232) at the bottom of this plug (230), and the wire itself (200) passes into the channel (233) in the middle of the plug (230). After this transition process, when the plug is placed in the plug socket (251 ) of the upper jaw bed (250), the tabs (234) prevent the plug from coming out of the slot, and the wire (200) fixes the knob (240) at the top. This fixing process is performed by placing the wire in the knob (240) slot, folding it, and compressing it in the partial gap (241) between the plug and the upper jaw support.

The upper jaw bed (250), which is fixed to the frame holder body using pin (140), closes the catching mouth (150.1 ) by making a smooth circular motion in the D1 direction in the center of the pin (140) at the point where it is fixed when the tensioning device stretches the tension wire (200). When the tension wire (200) is released, there is a driving element (150) that allows the capturing mouth (150.1 ) to be opened due to the movement of the upper jaw bed (250) in the D2 direction, contrary to the smooth circular motion mentioned above. This driving element is preferably a spring.

By means of the tension wire (200) passing through the partial space (241) in the rear part of the movable jaw (120), the drunken movement of the movable jaw (120) during the opening and closing of the gripping mechanism (100) is prevented.

In Figure-1 , the ability to take the most appropriate position according to the shape, form, and diameter of the fixed bicycle frame while tightening due to the fixation of the movable jaw (120) in the center E and its angular motion (D3-D4) is shown.

The frame holder has a conical surface (340) so that the lower fixed jaw (110) is connected to the upper end of the supporting arm and inserted inside the arm. The frame holder locking piece (350) is also fixed to this conical surface with the help of the connector (330) and the nut as connecting elements without tightening it to the end. There is a transition hole (341 ) that allows the tension wire (200) to pass through this section and go through the supporting arm.

After the locking part (350) of the frame fixed jaw (110) is attached to it, the supporting pipe (301 ) is passed to the tip (360), and the connector (330) is started to be tightened. During the tightening process, the locking piece (350) moves in the D5 direction on the conical surface (340) without rotating around its own axis with the help of the gaps (351 ) on its outer surface and the curtains (352) corresponding to these gaps. As it moves in this direction, the extensions (353) of the locking piece (350) begin to open outwards, and the cadre fixes to the fixed jaw (110) by applying pressure to the inner wall of the supporting pipe (301).

As can be seen in Figure-7, the locking group (620), the tension guide bearing element (400), the nail surface (622) configured on the tension element (530), which is the main gear, claw spring (623), gear locking tongue (621 ), and lock trigger element (610) are illustrated.

With the help of the clamping device handle, the tensioning element (530) is turned clockwise and stretches the wire (200) by wrapping it around itself.

When a force is applied to the pressing surface (534.1) of the clamping device latch (534), which is positioned on the gear locking tongue (621 ), in the D12 direction, the locking tongue (621 ) moves the tensioning element (530) in a circular manner in the D12 direction, thereby releasing the tension element (530).

Locking unit (600); Thanks to the lock trigger element (610), the movement of the clamping device latch (534) is blocked, and the mechanism is secured. However, even if the product is locked, if the tension wire (200) is not stretched enough, the lock trigger element (610) can be turned in the direction of tightening the handle, and the stretching process can be continued without having to open it again. The locking element consists of two parts in the form of a clamping device latch (534) and a threaded locking tongue (621), which allows for performing the clamping process while the product is locked. Otherwise, if the product is locked without sufficient tightening, it will be necessary to open the lock to continue squeezing. The wheel fixing unit (700) is illustrated in Figure-6. The belt catches and compresses the wheel, the belt and the ratchet mechanism that pulls the belt are brought and tightened according to the wheel's position by making a 90-degree movement where it is attached. It moves in profile thanks to the part that goes into the T-channel under it, and when its place is adjusted, it is tightened with the handle behind it and fixed in place.

Passing the tension wire (200) through the plug (230) and clamping it between the upper jaw rest (250) and the plug (230) is as follows; While the back wire (200) is inserted in the plug (230), the part with the knob (240) at the end enters the slot (251 ) of the plug (230) and is fixed on the cylinder surface (232). In this way, the process of holding on the surface prevents excess loads and deformation that may occur at a single point by distributing the load to the surface.

The tension wire (200) joins the system by passing through the gap opened into the plug (230). The tension wire (200) stretches the clamping device latch (534) so that the movable jaw (120) approaches the fixed jaw (110) and holds the bicycle body between the jaws by compressing.

Breakage or deformations that may occur in the tension wire (200) or the knob (240) part of the wire due to the load to be formed in this compression process: The tension wire (200) is blocked by passing it through the gap in the plug (230), compressing it on a large surface between the plug (230) and the outer support element, and fixing the knob (240) to the lower cylindrical part of the plug (230).

After the tension wire (200) is entangled in the plug (230), it is attached to its place on the upper jaw bed (250), while the tension wire (200) is compressed on the junction surface of the plug (230) and the upper jaw bed (250). In this process, by compressing the load created by stretching the wire (200) between two surfaces, not at a single point, the load is distributed on the surfaces as well, preventing the wire from being dislodged and reducing the load to be transmitted to the plug (230).

In cases where the wire (200) does not pull the knob (240), that is, the product is not in use, the plug (230) will remain in place thanks to the nailed structure (234) at the bottom so that it does not move out.
