The invention relates to roof bars adapted to vehicle roof surfaces in order to allow placing extended items which are not suitable for placing in the trunk when the vehicle trunk is insufficient.

Prior Art

Load carrier roof bars are auxiliary automotive components that are fixed on vehicle roofs and used for carrying loads. In cases where the vehicle trunk is insufficient, extended items which are not suitable to be placed in the trunk are placed in the vehicle roof area. On the other hand, roof bars are used in order to distribute this load to the carrier framework structure of the vehicle and to ensure that the roof is not destroyed due to the load.

Hence, fixing the roof bars which are fixed on the vehicle roof surface is of great importance. The roof bars used in the state of the art have a multi-pieced structure which require long assembly time.

In a patent research conducted in relation to the prior art, a patent numbered EP0635397A1 was found. This application mentions a roof bar that is fixed on the vehicle roof. It comprises two rails fixed to the roof and at least two cross pieces. The two cross-pieces locked on it contain opposite faces that can be applied directly to each other to form an aero foil.

In the application number DE4315029A1 ; a roof rail for motor vehicles comprises a profile cross carrier, which is supported by means of carrier legs at both ends of a profile roof. Covers are arranged with locking cover elements on the support legs. According to the invention, each cover has a slot inside which a rocker is present, arranged with a therein to a horizontally oriented axis having pivot able rocker as a locking member, which is equipped with a group consisting of lock and lock bolt locking unit.

Another application is patent no. TR2016/17438 belonging to Tofa§ company. This application discloses a roof load carrier system comprising two roof bars on both sides of the vehicle, in the form of rods extending along the vehicle roof for carrying and/or attachment of loads, and at least one rack extending perpendicular from one roof bar to the other roof bar in the form of a rod.

Detailed Description of the Invention

In Figure-1 , the load carrier roof bar (100) adapted to the upper roof outer surface of the vehicles comprising the upper jaw body (201 ) jaw assembly (200) and the bar body (300) is illustrated. As can be seen in assembled and exploded views of figures-2 and 3; it comprises a moving jaw (203) fastened to the fixed upper jaw body (201) by means of a connector (204) and a loop radius (223) which allows the partial circular motion of the mentioned moving jaw (203) in s2 - s2 directions (see figure-6). By means of the loop radius, the connection traverse on the vehicle is ensured to receive and fasten the jaws easily and quickly. Moving jaw (203) is made of metal-based material, and resistance enhancing surfaces (203.1 ) are formed on it. It also contains a soft layer (207) comprising knurled surfaces adapted to the fixing surface (206) of the moving jaw (203).

In addition, it comprises a fixing nut (205) comprising a radius bearing (205.1 ) which provides a bearing for the mentioned loop radius (223) and at the same time, ensures fastening the moving jaw (203) and provides the desired partial turn and at least one channel screw (212) to secure the mentioned jaw assembly (200) to the jaw body (300). By tightening and loosening the channel screw (212), the traverse that remain between the upper jaw body (201 ) lower moving jaw (203) is compressed. With the vertical linear motion on Z1 and Z2 axes produces both tightening and loosening motion (see figure-6).

On the other hand, it comprises a compression wedge (210) which is provided to make compression motion along the vertical z1 - z2 axis by pushing and pulling the channel screw (212) on the horizontal axis along y1 - y2 directions and at least one clip (220) comprising a pin (221) which is attached to the pin hole (302) with an elastic motion by engaging the jaw assembly (200) compression arms (209) to the compression gap (303).

This clip (220), shown in Figure-5, has a flexible body (222) and while it is placed inside the bar body (300), it flexes before entering the pin hole (302), allowing the pin (221 ) to be seated inside the hole. The mentioned clip (220) is placed in the clip channel (219) where it carries out its function.

In Figure-6, the cross-section view of the screw holder (224) part is given. The screw holder part (224) moves linearly in the Y2 direction when the channel screw (212) is tightened using an Allen key. Flowever, the linear motion of the channel screw (212) is not desired. The screw holder (224) acts as a retaining part to keep the screw steady on the axis of rotation while rotating the screw (212), preventing the linear motion of the screw (212) in the Y2 direction.

In figures-7 and 7.1, close-up exploded views of the upper jaw body (201) key (214) and key hole (215) are illustrated. With the notch (214.1) and the locking tab

(214.2) formed on the key (214), seating and locking the key (214) inside the key hole (215) is endured. In addition, the desired locking is established with the notch bearing (215.1) and the lock bearing (214.3) formed in the key hole (215).

In Figure-4, a close-up illustration of the inner nut (212.1) configured inside the compression wedge (210) is given. A wedge angled surface (218) which provide the angular motion along the z1 and z2 directions by providing the helical motion of the inner nut (212.1) is introduced. A channel angled surface (217) which has the same angled surface as the mentioned wedge angled surface (218) and thus provides compression movement is introduced. In the cross-section view given in Figure-6, linear motion along the Y1 and Y2 axis converted into Z1 and Z2 angular vertical motion. In other words, a helical motion is provided for the inner nut (212.1) by means of the channel screw (212), and while the inner nut (212.1) advances the compression wedge (210), with which it is connected, in the Y2 direction, it applies pressure motion towards the Z1 direction along with the opposite channel angled surface (217) and its own angled surface. This pressing motion provides compression and fixing by means of the pressure exerted by the upper jaw body (201) and the bar body (300) to each other from inside. On the other hand, a body bearing (202) which comprises a bearing gap (216) where the inner jaw (208) and compression arms (209) of the upper jaw body (201) and bar body (300) are seated all together and grip surfaces (202.1) is provided. This body bearing (202) and the bar body (300) have the same ellipse form. Thereby, design integrity is established.
