SUMMARY OF THE INVENTION

The luggage carrier according to claim 2, fastened to the towing ball by means of a fastening device according to claim 1, a retractable luggage compartment according to claim 4, fastened to the luggage carrier by a blocking-locking device according to claim 3, which is part of the luggage carrier a carrier and a bicycle carrier according to claim 5.

The invention consists of several separate devices which can be combined into a compact unit and used in several variants. An explanation of the nature of the solution of individual devices is given in the following text.

A retractable luggage compartment comprising a hinged lid, a central panel, a lower panel, an upper panel and a bottom, which can be retracted from one another, having upper reinforcing flanges on the upper edge and lower reinforcing flanges formed on the lower edge. The central panel, the lower panel and the bottom have press-fit guide pins and fixed elastic panels in the upper reinforcing skirt to prevent the retracted parts of the retractable luggage compartment from sliding in the spontaneous way. Furthermore, there are molded fixed pins around which the reinforcing arms can be pivoted, provided with holes for engaging the shoulder pins after turning the reinforcing arms to a position that follows the line parallel to the side walls of the retractable luggage compartment. Strengthening arms

C f c provide higher rigidity and dimensional stability with a higher load on the luggage compartment. The bottom has stiffening ribs in which fixing holes are provided, into which the locking pins of the locking-locking device are inserted when the luggage compartment is clamped. The advantage of this retractable luggage compartment over other solutions is that it occupies several times less space in the retracted state than in the extended state and can be stowed in the luggage compartment of a car where it occupies only a fraction of the space and can significantly increase the luggage compartment of the small car. after its attachment to the luggage rack.

A fastening device having at least one bearing continuous projection and one bearing intermittent projection provided on the inner surface of the body, of which the lower intermittent projection is interrupted in the front part of the body, at the front recess. An upper plate with a large pitch thread is fastened to the body from above, into which the locking lever is screwed. In the side walls of the body there are lateral recesses in which the locking lever engages rotatably mounted on the fastening pin. The locking lever is equipped with a shoulder with a retaining pin pushed by a retracting spring. Two lower plates are welded to the lower part of the body, between which there is a gap of the width of the hook of the towing device, to which the front recess in the front part of the body is connected. Before the front recess, there is a stop body and a stop lever in the body. Clamping to the ball of the towing device is accomplished by sliding the body onto the ball of the towing device, whereby the ball is seated on the continuous and intermittent engaging projections formed on the inside of the body. Then, the locking lever is slid into the recesses in the side walls of the body, thereby securing the body to the ball of the towing device and rotating the articulated lever, whose bolt engages a flat ball surface, clamps the body so as to prevent movement of the body relative to the ball of the towing device. The pivoting around the horizontal axis of the tow ball that is perpendicular to the direction of travel of the vehicle is made possible by turning - releasing the locking lever so that it does not interfere with the inner space of the body, thereby making the body freely rotatable on , which is adjustable by an adjustable stop lever. Unwanted rotation in another direction is provided by stabilizing arms resting on the hook of the towing device, which are fixed to the lower plates. If the device needs to be rotated about the vertical axis of the tow ball, the clamped locking lever will only be released so that the lever is in contact from a flat surface on the tow ball without the clamping force being applied and the stabilizing arms are released at the same time. By locking the locking lever with the lock (the lock is not shown), the fastening device can be locked on the towing ball and, at the same time, the luggage rack can be locked together after inserting its cross tubes into the horizontal connecting tubes and inserting the retaining tab under the locking lever. the retaining pin engages in the oval opening in the retaining tab. An advantage of the fastening device is the lockable connection with the tow ball at very small dimensions, with the possibility of positioning rotation on the tow ball about its horizontal axis perpendicular to the direction of travel, or about its vertical axis, and lockable luggage rack or bicycle rack.

A luggage rack based on a supporting frame welded from the main profile, two short profiles, two transverse tubes, two upper tubes, the connecting profile, the four locking tubes and the supports on which the three-part grate is supported, consisting of two outer retractable grilles retractable under a fixed floor grate fastened to the support frame by threads, pivoting mounted tilting arms which can be folded to rest against the grate, hinged front posts made of retractable posts retractable into main posts welded to rotary tubes which can be rotated and slid into the supporting tubes of the supporting frame, which allows

Ich Γ e e ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich ich. In the disassembled state, i. when the hinged arms and front pillars are tilted to vertical positions, these arms and pillars are locked in these positions by locking pins passing through the locking tubes and short profiles and spring loaded by a ring and a cotter pin. The advantage of the luggage carrier is that its folding reduces the space occupied by it several times compared to its unfolded state, allowing it to be stored in the luggage compartment of a car where it occupies only a fraction of the space or stored in the retractable luggage compartment when it is retracted.

The locking device, which is part of the luggage rack, enables the folded-down arms and front pillars of the luggage rack to be locked in vertical positions by locking the crossbars carried by the locking tube small and long against the locking pins and sliding the locking stops between the locking lugs , after the small and long blocking tubes have been pulled out together and then the locking rod is inserted into the positioning holes made through these tubes. At the same time, the retractable luggage compartment (or suitably suitcases, crates, etc.) can be fixed and locked, which has fixing holes in the bottom so that the clamping pins mounted on the locking cross bars sliding together with the locking tube are small and long. Turning the lock fixed in the hinge welded to the support frame locks the locking bar, inserted into the positioning holes and locks the lock as well as all hinged arms, front pillars and clamped retractable luggage compartment. The advantage of this locking-locking device is that by simple movements (moving the small tube, the big tube and the locking bar) and locking the lock, several parts of the luggage rack are locked and locked together with the possibility of simultaneously clamping and locking another device (retractable luggage compartment) , suitcase ...) stored on the luggage rack rack.

The bicycle rack is formed by sliding the legs of the bicycle holders into the vertical connecting tubes of the fastening device and tightening the connecting screws. The bicycle holder is formed by a foot which is pivotally connected to the pivot arm by means of a bearing pin, to which the bearing U-pad and the connecting U-pad are welded. The fastening U is provided with a fastening hole through the swivel arm, which fits a plug pin with a shoulder on which a spring supported by a hinge welded to the foot is pressed. The ring controls the plug-in pin. A movable lever is slidably and rotatably mounted in the guide tube on the bicycle holder leg. By sliding the movable lever under the lever of the locking lever, the retaining pin engages in the oval locking hole in the movable lever. This ensures that by locking the locking lever with a lock (the lock is not shown), the bicycle carrier can also be locked on the balls of the towing device at the same time. The bicycles are fixed to the bicycle rack by placing their frames on the swiveling swivel arms to which they are clamped by clamping hooks and nuts. The advantage of the bicycle carrier is that it can be tilted around the horizontal axis of the ball of the towing device of the car perpendicular to the direction of travel of the car, or it can be rotated around the vertical axis of the towing ball of the towing device. An advantage of the bicycle carrier is that its solution is arranged to be of optimal size and can be stored in the retractable luggage compartment in the retracted state while at the same time guaranteeing its rigidity and stiffness in the unfolded state. This allows the straight leg of the square tube cross-section and the circular tube cross-section to be rotatably connected by placing a shoulder at one side of the U-leg with a shim on the side of the swivel joint and a washer on the other side Possibility of extreme pressure occurring in the contact of the leg - arm, arm - pin, when the arms are loaded by the clamped bicycles from the application of the respective frrrrr centrifugal force, exerting moment of force acting on the swivel arms when the car is bent.

The proposed complex device allows to transport several times the volume that occupies the device in the collapsed state, and all components of the proposed device can be stored in the retractable luggage compartment when in the retracted state. Thus, the volume of luggage carried by a smaller passenger car can be substantially increased, varying its use for transporting bicycles, suitcases, crates, containers, etc., while occupying only a fraction of the luggage compartment of the car. The device can tilt and swivel around the tow ball, while attaching and locking it on the tow ball, providing convenient access to the luggage compartment of the combi and hatchbeck cars with the tailgate. The proposed device also has the advantage that all parts of the luggage rack are locked in this state and unlocked in this state by one mechanism and lock, with the possibility of simultaneous locking of the retractable luggage compartment (or adapted suitcase, ...). the fastening device can be further clamped and locked by a simple mechanism to the fastening device which is simultaneously locked on the ball of the car towing device with the same lock (a similar procedure applies to fastening and locking the bicycle rack), which has the advantage of simply locking the entire universal carrier assembly with retractable luggage compartment.
