[0002] FOLDABLE BICYCLE TRAILER

[0003] Technical Field

[0004] The subject matter of this invention relates to a bicycle trailer with a foldable design made from a single piece, which aims to facilitate and ergonomically assist users in carrying and transporting shopping items from the market and grocery store.

[0005] Prior art

[0006] Nowadays in traffic, many times, the transportation of groceries and shopping materials from the market and bazaar is carried out unsafely without any precautions using vehicles such as bicycles, motorcycles, and electric bicycles. This situation poses a safety risk for users and creates a dangerous situation in the existing traffic. Additionally, carrying an excessive load beyond what is necessary poses a threat to human health. This situation also leads to an increase in our health expenditures and raises the country's current account deficit economically speaking. This situation leads users to carry their groceries and shopping materials from the market or store either in uncomfortable and impractical shopping carts or by hand, carrying bags in each hand, creating health problems for users. In addition, the rapid malfunction of impractical shopping carts has negative effects both personally and on the country's economy.

[0007] Since a person cannot carry more than two shopping bags at the same time and go to the bazaar and the market with a motorized vehicle, even if it is a short distance, causes problems as mentioned above, studies have been carried out in the current technique on the integration of market vehicles into bicycles and derivative vehicles. One of these is the file numbered TR.2011 / 04713, which pertains to wheeled trailers connected to metal baskets or extensions behind transport vehicles such as bicycles and motorcycles. In the space inside the trailer hitch profile formed in the front part of the trailer body, there is a telescopic rod profile that can be adjusted in height by moving up and down. Due to the tied rod connected to the end of this telescopic tie rod profile, the plane differences and axis differences of the vibrations that will occur when the motorcycle or bicycle moves are absorbed, ensuring that the trailer connection is always strong and the wheels connected to the trailer body are always fully pressed to the ground. Furthermore, with the help of this rod, the reverse thrust force created during the direction change of the motorcycle is damped, and a smoother direction change is provided, thus preventing damage to the object carried in the trailer. In order to connect the trailer to the motorcycle, first of all, the upper plate is placed on the lower plate located on the motorcycle's rear carrying ledge behind the motorcycle and fixed to the motorcycle's rear metal carrying ledge with fastening bolts. The trailer is fixed to the motorcycle by mounting it on the rod and rod-clamping protrusion at the front end of the telescopic rod profile. However, the trailer subject to the invention is non-foldable and is made of heavy metals. For this reason, it is not possible to enter a shopping center with the inventive trailer.

[0008] Again in the present state of the art, the file numbered US4371184A relates to a bicycle trailer developed for towing behind lightweight, self-propelled vehicles such as bicycles. The subject matter of the invention is to provide a coupling that reduces the impact of the trailer on the bicycle and reduces the bicycle's leaning restriction, especially when cornering. It has a body to carry a payload, a pair of wheels, a drawbar extending from the body to connect to a towing vehicle, and a linkage for releasably connecting the free end of the drawbar to a towing vehicle. When the pull rod is not needed, it can be easily removed or reversed by loosening the screw. Although US Patent US4371184A describes an invention related to a bicycle connection device, the existing pin in the relevant invention is prone to getting lost and does not provide user convenience. In addition, wear and tear due to disassembly and assembly can lead to problems after some period of use.

[0009] In the known application of the technique, the presence of a compact structure bicycle trailer with a retractable handle that can be easily stored is known. The bicycle trailer in the current state of the hbfart includes tool-free installation and quick connections that can be adjusted according to different bicycles. It also includes a retractable towing handle for use with bicycles with larger tires. As for the bags, it include a transit mail carrier bag, a backpack, an upper market bag, and a lower market bag. However, the technique in the current state of the art, as the materials inside the bag on the trailer are free, rub against the tire, and hinder driving. Therefore, the user has to control the trailer every time and it is not possible to transport heavy materials without damage. The load compartment was left free with only a bag structure and the load overflows left and right, making it difficult to drive. In the examinations and research carried out, unsuccessful solutions to the technical problems related to the existing bicycle trailers carrying the existing market shopping, have shown the inadequacy of the existing solutions making it necessary to make a development in the relevant technical field.

[0010] The Aim of the Invention

[0011] The main purpose of this invention is to develop a bicycle trailer with a foldable structure that will be a solution to all technical problems existing in the present art. Thanks to the foldable side and base frame connected by means of hinged connections positioned on the playwood frame with a water-repellent feature, the materials placed in the bag on the trailer are prevented from rubbing against the wheel. In terms of the structure, the wheel is idle, and the material placed on it and the wheel do not come into contact with each other by any means, and are independent. In this way, the materials inside the trailer are not damaged and are prevented from overflowing around, and the trailer functions as a truck body, which allows a safe drive in the traffic. In addition, due to these two side walls in the shape of a truck bed; the reverse thrust force that occurs during the change of direction of the bicycle is damped, and a safe change of direction is ensured, thus preventing damage to the object carried in the trailer and preventing the trailer from flipping.

[0012] In addition to all these, there is a foldable top bag and bottom bag on the trailer subject to the invention and includes elements that provide ease of shopping. The trailer can be easily attached and removed and does not require tools. Alternatively, the upper bag can be produced as isolated.

[0013] The advantages of the foldable bicycle trailer which is the subject matter of the invention can be listed as follows.

[0014] - It is an ergonomic product that provides user convenience.

[0015] - It provides a foldable compact body design and transportation advantage.

[0016] - There is a saddle connection drawbar design.

[0017] - It has an easily mountable wheel hub axle locking mechanism.

[0018] - It has a rigid body with a capacity of 40 kg.

[0019] - It provides a low-cost advantage. Detailed Description of the Invention

[0051] The bicycle trailer(A) subject matter of this invention, is connected to a bicycle in Figure 1, and its general form is shown in Figure 2, said bicycle trailer(A) moves on wheels(l). The wheels(l), which provide movement, have double bearings that facilitate mounting and dismounting on the bicycle trailer(A). Due to the double bearing structure of the wheels(l), when the center of the wheel(l) is pressed, the horizontal pin inside moves forward and the vertical pin moves down. Thus, the wheels(l) can be easily removed from the place where they are installed.

[0052] A hanger bracket(3) is connected to the foldable connection arm(5) and the bicycle trailer(A) can be attached to bicycles or motorcycles by connecting the connection apparatus(2) to the other end of the said hanger bracket (3). In addition, when the bicycle trailer(A) is not being used attached to the bicycle, they can also use it as a shopping cart by pulling the bicycle trailer(A) by grasping the handle(5a) on the connection arm(5). In the connection arm(5), which has an open and closeable structure, there are two plastic buttons and these buttons are used to open the connection arm(5) and bring it to the desired connection position. In order to bring it to the desired connection position, it is necessary to press the two plastic buttons on the connection arm(5) at the same time. In this way, the connection arm(5) is opened and brought to the connection position.

[0053] The bicycle trailer(A) has a total of three frames(4), two on the side and one on the base, and these frames(4) are foldable. The frames(4) are connected to the bicycle trailer(A) by means of the hinges(lO) positioned on the back(9). The frames(4) can be folded up to 90° degrees along its axis through hinges(lO). The bicycle trailer(A) is foldable thanks to the hinged(lO) structure of the frames(4) and takes up less space in the trunk of the vehicle or in other places. The frame(4) is connected to the base of the rear frame(9) by hinges(lO) and has a hole(14) on both sides. When the bicycle trailer(A) is folded, there are slots(16) in the rear frame(9) to which the wheels(l) can be liaison. When the frame (4) at the base is folded onto the rear frame (9), there is a slot (16) on the frame (4) positioned on the base, which is formed to coincide with the projection of the slot (16) in the lower region formed on the said rear frame (9). There is one leg(ll) on each of the lower parts of the frames(4) of the bicycle trailer(A), which are again connected to both sides of the rear frame(9) through hinges(lO) to ensure the balance of the trailer. There is a bracket(12) with protrusion(13) vertically connected to the leg(ll). These protrusions(13) pass through holes(14) in the base of the frame(4). This way, three frames(4) are fixed together.

[0054] The rear frame(9) and frames(4) that constitute the main frame of the bicycle trailer(A) are made of playwood material with water-repellent properties. Thanks to the foldable side and base frames(4) connected by means of hinges(lO) positioned on the rear frame(9), the materials placed in the upper and lower bags(6,7) on the bicycle trailer(A) are prevented from rubbing the wheel(l). By its structure, the wheel(l) is idle and the materials placed on it do not come in contact with the wheel(l). In this way, the materials inside the bicycle trailer(A) are not damaged and the overflow is prevented. In addition, due to these two side frames(4) in the shape of a truck bed, the reverse thrust force generated during the change of direction of the vehicle is damped, and a safe change of direction is ensured. In other words, if the vehicle turns to the right or left while traveling, the lower and upper bags(7,6) of the bicycle trailer(A) tend to tip over in the direction opposite to the direction of rotation together with the load inside. Due to the frames(4) on both sides, negative situations such as tipping and falling of the upper and lower bag(6,7) are avoided. In the meantime, as above mentioned the frames(4) cut the connection between the wheels(l) and the lower bag(7). When the bicycle trailer(A) is in motion, thanks to the frames(4), the lower bag(7) does not touch nor rub the wheels(l). In this way, since the wheels(l) do not rub against the fabric of the lower bag(7), the fabric is not abraded and damaged. In short, the use of frame(4) prevents undesirable situations such as the damage of objects carried in the bicycle trailer(A) and the flipping of the bicycle trailer(A). Thanks to the connection apparatus(2) that allows the bicycle trailer(A) to be connected to the bicycle and / or motorcycle, the said bicycle trailer(A) can be easily removed and attached from the bicycle and / or its rear. The top bag(6), which is connected to the upper part of the bicycle trailer(A), has a foldable structure 90° degrees of the base and takes up less space. The upper bag(6) has a separate compartment for items such as money and phone and can be easily disassembled and assembled. The lower bag(7), which is separately connected to the lower part of the bicycle trailer(A), in other words, the lower part of the upper bag(6), has a 900 foldable base. The lower bag(7) takes up less space due to its foldable feature. Thanks to the tension ropes on the lower bag (7), the mouth of the said lower bag (7) is contracted, and the contents are prevented from scattering. Another point is that both the upper bag(6) and the lower bag(7) can be easily removed and installed from the bicycle trailer(A). In order to attach or detach the upper bag(6) and lower bag(7) from the bicycle trailer(A), the belt buckle(8) shown in Figure 3 can used.

[0055] After the upper and lower bags(6,7) are removed from the bicycle trailer(A), the rear frame(9) remains empty as shown in Figure 4a. As shown in Figure 4b, the first part of the bicycle trailer(A) to be folded is the frame(4) that connects the rear frame(9) to the base. By lifting the frame(4) upwards and removing the protrusions(13) from the holes(14), the said frame(4) is leaned against the rear frame(9). (Figure - 4c) Then the frames(4) connected to the two sides of the rear frame(9) are closed on the said rear frame(9). (Figure - 4d and Figure - 4e) During this folding, the brackets(12) that are fixed to the legs(ll) of the lower part of the frames(4) pass through the cavity(15) formed in the frame(4) located on the rear frame(9). Finally, the wheels(l), thanks to their double bearing structure, are pressed out from the center and passed through the slots(16) formed on the rear frame(9) and the frame(4) connected to the base. (Figure - 4g) In this way, the bicycle trailer(A) is fully folded and ready to be connected to the vehicle (Figure - 4h and Figure - 4i).
