Description

[0001] The invention relates to a transport device for transporting persons and / or luggage according to the features of the preamble of claim 1, and to a method for converting a transport device for transporting persons and / or luggage from a kick scooter to a handcart or vice versa according to the features of the preamble of claim 13.

[0002] Scooters are available in many different versions, including those with or without electric drive and with two or three wheels. These scooters are designed to cover short distances as quickly as possible. Foldable scooters are also available for transport by car or train. However, scooters are only suitable for transporting loads to a limited extent, as they lack a mounting bracket or a wide storage area, for example.

[0003] Transport devices for luggage or loads in the form of handcarts are known in a wide variety of designs, with or without electric drive or with specially designed wheels for negotiating stairs. However, these handcarts cannot be used to transport people. DE 29715152 U1 discloses a scooter or kick scooter consisting of a frame to which a rear wheel, a front wheel steerable via a handlebar, and a footboard are mounted. The frame and footboard are each split in two transversely to the longitudinal direction and designed to pivot about a hinge. The split footboard is designed symmetrically to the dividing plane running through the hinge. In this way, after the rear part of the scooter has been folded forward around the hinge, a luggage cart is created which, using the handlebars, can be used like a sack barrow to transport shopping or luggage.

[0004] The object of the present invention is to provide a transport device with extended functions that is easy to handle and easy to manufacture.

[0005] The object is achieved according to the invention by a transport device for transporting persons and / or luggage according to the features of claim 1.

[0006] The solution according to the invention is a transport device for transporting persons and / or luggage, wherein the transport device has a transport board, a handlebar, a front wheel element and a rear wheel element, and wherein the front wheel element has at least one front wheel and the rear wheel element has at least one rear wheel. It is essential that the transport board, the handlebar, the front wheel element and the rear wheel element are each designed as separate assemblies, and that the transport board and / or the handlebar and / or the front wheel element and / or the rear wheel element have one or more connection points for connecting the assemblies to one another, and that the transport device can be converted from a kick scooter to a handcart by means of the separate assemblies, in that the connection points are designed such that in a first grouping the assemblies are arranged by the connecting points to form the scooter, and in a second grouping the assemblies are arranged by the connecting points to form the handcart, and that in the first grouping the front wheel element, the transport board and the rear wheel element are arranged one behind the other, preferably in a line or a plane, and that in the second grouping the front wheel element and the rear wheel element are arranged on the transport board rotated by 90° to the first grouping, preferably on the same side of the transport board.

[0007] The solution according to the invention further relates to a method for converting a transport device for transporting people and / or luggage from a kick scooter to a handcart or vice versa, wherein the transport device has a transport board assembly, a handlebar assembly, a front wheel element assembly with at least one front wheel and a rear wheel element assembly with at least one rear wheel, and wherein the assemblies are arranged in a first grouping, the assemblies for forming the kick scooter, in that the at least one front wheel and the at least one rear wheel are arranged one behind the other, preferably one behind the other in a line, and in a second grouping, the assemblies for forming the handcart are arranged in that the at least one front wheel and the at least one rear wheel are arranged parallel to one another.It is important to note that the conversion from one group to another involves the following steps: . Detaching the rear and front wheel elements from the transport board, connecting the front and rear wheel elements at the first connection points of the transport board to form the scooter, or at the second

[0008] Connection points of the transport board for forming the handcart, wherein the first and / or second connection points are formed on the transport board and / or on the front wheel element and / or on the rear wheel element.

[0009] The advantage of the transport device is that it can be converted from the first grouping to the second grouping very easily and manually without the need for tools. In the first grouping of components, the transport device is a kick scooter for transporting people. In the second grouping of components, the transport device is a handcart for transporting luggage or loads. The same components are used in both the first and second groupings to create the kick scooter or handcart. A further advantage is that individual components can be replaced for repairs, thus eliminating the need to replace the entire transport device. Furthermore, different components can have different design elements and these can be combined with one another as desired.

[0010] The front wheel and / or the rear wheel can be designed as a pneumatic wheel, rubber wheel, with suspension and / or without suspension. The front wheel and / or the rear wheel can also be designed with ball bearings. The advantage of this type of design enables people and / or goods to be transported quietly. State-of-the-art scooters or trolleys often use simple plastic wheels, which means that a loud noise is created when the wheels roll. The use of ball-bearing wheels or pneumatic tires or rubber wheels and / or appropriately suspended wheels leads to much lower noise development when rolling and, as a result, to less noise pollution in the environment.Furthermore, the use of such wheels decouples the transport area with the goods or people from the road surface through the wheels, thus resulting in a good and stable driving experience and less noise.

[0011] It can be provided that the transport board, the handlebar, the front wheel element and / or the rear wheel element are made of aluminum, an aluminum alloy, plastic, fiber composite and / or carbon.

[0012] Advantageously, it can be provided that a receptacle for holding a transport container, preferably a suitcase or a bag, is formed on the handlebar and / or on the transport board.

[0070] In Fig. 8 Parts of the assemblies of the transport board 4, the handlebar 5, the front wheel element 6 and the rear wheel element 7 are shown as an exploded view; this corresponds to the scooter 2 in Fig. 1 . In the Fig. 9 and 10 The components of the transport device 1 are shown as an exploded view in the second grouping as handcart 3 in front view and rear view; this corresponds to the handcart 3 from the Fig. 2 and 3 .

[0071] In the examples of the Fig. 1 ,2 and 3 and the Fig. 8 , 9 and 10 the front wheel element 6 and the rear wheel element 7 each have two connection points 8, ie the first front wheel element connection point 81vR, the second front wheel element connection point 82vR, the first rear wheel element connection point 81hR and the second rear wheel element connection point 82hR, which are each formed rotated by 90° to each other. In these embodiments, these connection points interact with the first front transport board connection point 81vT and the first rear transport board connection point 81hT in such a way that in the first grouping in Fig. 1 and 8 the assemblies transport board 4, front wheel element 5 and rear wheel element 6 are arranged linearly one behind the other and in the second grouping in Fig. 2 , 3 , 9 and 10The assemblies of transport board 4, front wheel element 5 and rear wheel element 6 form an H, with the transport board 4 forming the central beam of the H. Designs are also possible in which the two connection points are formed on the transport board 4, rotated by 90°, as in Fig. 4 shown schematically.

[0072] In the Fig. 11a und 11b Embodiments of the connection points 8 are shown, ie the first front transport board connection point 81vT, the second front transport board connection point 82vT, the first rear transport board connection point 81hT, the second rear transport board connection point 82hT, the first front wheel element connection point 81vR, the second front wheel element connection point 82vR, the first rear wheel element connection point 81hR and / or the second rear wheel element connection point 82hR can be as shown in the Fig. 11a and / or Fig. 11b shown. The connection points listed above are generally referred to below as connection points 8.

[0073] Fig. 11b shows a receiving connection point 81 and Fig. 11a shows an engaging connection point 80. The connection points 8 in the preceding Fig. 1 bis 10 , ie the first and second connection points of all assemblies, can be designed as an engaging connection point 80 or a receiving connection point 81, wherein in each case an engaging connection point 80 cooperates with a receiving connection point 81 for fastening assemblies.

[0074] The engaging connection point 80 is in the embodiment of the Figur 11a as a frame-shaped pin 82, which extends in the plane of the transport board 4, the front wheel element 5 and / or the rear wheel element 6. At the front end of the frame-shaped pin 82, a step 87 is formed. The frame-shaped pin 82 is penetrated in its plane by a rung 83, which in the embodiment of the Fig. 11a extends through the frame-shaped pin 82 and is formed as a rectangle with a rounded top. A locking rocker 86 is rotatably attached to the rung 83. The function of the locking rocker 86 is described in the Fig. 13 described.

[0075] The receiving connection point 81 in Fig. 11b is a counterpart to the engaging connection point 80 of the Fig. 11a The receiving connection point 81 has a U-shaped groove 84 with a protruding nose 88 on the top side of the assembly for receiving the frame-shaped pin 82, and a groove 85 on the bottom side of the assembly for receiving the rung 83. The U-shaped groove 84 has an undercut 89 for receiving the step 87.

[0076] The Fig. 12a bis 12c show the connection of the engaging connection point 80 and the receiving connection point 81. For this purpose, in a first step, the rung 83 is inserted from below into the groove 85, whereby the nose 88 engages the frame-shaped pin 82. The two components are then transferred to the same plane by a tilting movement, whereby the frame-shaped pin 82 engages the U-shaped groove 84.

[0077] To secure the connection, as described in the Fig. 13 shown, the locking rocker 86 is moved into a locking position. In Fig. 13a The two connecting points 80 and 81 are connected to each other, but still have a gap, since the step 87 does not yet engage in the undercut 89. To transfer it to the locking position, the locking rocker 86 is rotated upwards out of the plane of the assembly ( Fig. 13b ). This allows the two modules to be moved into each other ( Fig. 13c ), whereby the nose 88 occupies part of the space of the locking rocker 86 and the step 87 engages in the undercut 89. Subsequently, the locking rocker 86 is moved to the left again into the plane of the two assemblies, but this time it prevents the two assemblies from being released, or in a first step, from being pulled apart.

[0078] The Fig. 14 show the assembly of the front wheel element 6 from the components as in Fig. 6 shown for the first grouping for the formation of the scooter. The front pin 67 of the front wheel element 6 is pushed into the front groove 68 of the front wheel suspension 65 ( Fig. 14b ). The front axle 66 is inserted into the holes 90 and 91 in the front pin 67 and the front grooved jaws ( Fig. 14c und 14d ). The steering rod 5 is arranged with the first steering rod connection point 81L adjacent to the third front wheel element connection point 83vR on the front wheel suspension 65. For this purpose, the third front wheel element connection point 83vR on the front wheel suspension 65 has two grooves into which projections on the groove walls of the first steering rod connection point 81L on the steering rod 5 engage ( Fig. 14d and 14e ). The front axle 66 is secured by the steering rod 5.

[0079] The Fig. 15 show the arrangement of the handlebar 5 on the transport board 4 for the second grouping to form the handcart. The second handlebar connection point 82L on the handlebar 5 has a T-shaped groove and is designed as a counterpart to the middle transport board connection point 8mT on the transport board 4. The handlebar 5 is pushed onto the middle transport board connection point 8mT for connection and can be secured, for example, with a locking pin. The upper edge of the second handlebar connection point 82L on the handlebar 5 is not formed at a right angle to the tube 50, but has an angle greater than 90°. As a result, the handlebar 5 is arranged on the transport board 4 at a slight angle bent forward in the pulling direction, which leads to improved pulling properties of the handcart.

[0080] The Fig. 16a und 16b show the transport device 1 according to the invention in the second grouping as a handcart 3 with a transport bag 100. The transport bag 100 is arranged in this embodiment on the support surface of the transport board 4, the front wheel element 6 and the rear wheel element 7 and can be attached to the handlebar. The transport bag 100 is also designed as a shoulder bag in this embodiment. As in the Fig. 16a und 16b As shown, the transport bag 100 has fixed, extendable side walls, allowing the height of the transport bag 100 to be varied. The transport bag 100 can also be designed with foldable extension elements or expansion pleats to vary the height. To reduce the noise generated during luggage transport, the transport bag 100 can have a reinforced and / or sound-insulating base, in particular made of a dampening material, for example, a foam or rubber.
