Description

Field of the Invention

[0001] The present invention relates to a unicycle-type vehicle on which a person can be transported while standing.

[0002] The present invention also relates to a frame for a unicycle-type vehicle, such as a roller vehicle, which can transport not only people but also luggage. The luggage can have different sizes and is fastened along the traveling direction.

[0003] The present invention is intended to provide a universal luggage receptacle for such a unicycle-type vehicle, which, for reasons of an as stable and light construction as possible, is integrated together with a front-wheel receptacle and a guide-column receptacle in a common frame, which frame is connected to a pedal and a rear-wheel receptacle. Thus, the forces occurring should be received as effectively as possible and the structural expenditure and weight should be optimized. Background Art

[0004] Recently, both human-powered pedal roller vehicles and electrically driven electric roller vehicles or electric scooters - hereinafter also referred to as "roller vehicles" - have gained increased popularity, especially in populated areas.

[0005] These vehicles are generally used as supplementary means of transportation for the "first mile" and / or "last mile" and are parked somewhere before or after use or carried in other means of transportation.

[0006] Here, there is not enough space in the complementary means of transportation used (such as trains, cars) or in most public parking locations (such as in residential buildings). Transporting a roller vehicle, for example, into a building or into and out of a complementary means of transportation via stairs also requires a compact size and low weight.

[0007] If a roller vehicle is used more as a transport device rather than a sports or leisure device, then an additional requirement for the roller vehicle is the possibility of transporting luggage or a load.

[0008] Four solutions have been proposed so far:

[0009] 1. An irreplaceable luggage piece with attachments, the luggage piece being oriented along the travel direction (e.g., US9033350B2 / EP2540604B1, EP1138590A1, JP2009006107A, US2016 / 0144708A1, US2004 / 0094919A1, WO01 / 72164A1, CN108791621A) or transverse to the travel direction (e.g., CN201240476Y, DE10026184C2, EP3516982A1, US6460866, US9090274, US20130062377A1). Here, the luggage (mostly an upright box) contains the necessary attachments to convert the luggage into a roller cart. For travel, the attachments are pulled out or unfolded, and for carrying, they can be moved in or folded. Here, thus, the luggage piece itself is equivalent to a roller cart.

[0010] 2. A trolley with a roller cart attachment (such as a pedal) and a luggage receiving part transverse to the travel direction, (e.g., US20150122566A1, a trolley with a removable box: US20100213680A1). Here, for these attachments, the same content as in 1 applies.

[0011] 3. A usual roller cart having a luggage receiving part transverse to the travel direction on the front wheels (e.g., DE000010204478A1, DE202019103766U1, US20140061267A1, W0001995008466A1, EP000001704901A1, DE202008006764U1, US20130062377A1, DE102006042119A1) or having a square base (DE202004003741U1, DE102011106561A1).

[0012] 4. A usual roller cart having an upwardly open luggage container on the front wheels (e.g., DE3138095A1 / DE000008128047U1, US20160297459A1, US8534405, DE9403583U1, a combination of 3. and 4.: DE000029610975U1, DE102012007780B3, DE102006049770A1)

[0013] US9108695 describes a vehicle in which a vertical square frame serves not only as a luggage receiving part but also as a guiding device, a central receiving component for the front wheels and the seat (instead of a footrest), but here the luggage is not fastened to the surface but pushed into the frame.

[0014] Solutions with fixed luggage pieces and also solutions with luggage containers are less flexible in transportation. In the case of renting a trolley, the passengers also carry their luggage pieces with them.

[0015] Luggage carrier solutions that are transverse to the direction of travel or have a square base have disadvantages in terms of space requirements for larger luggage. Luggage pieces usually do not have a square base, i.e., long sides. These luggage pieces must be transported during transportation for reasons of forward tilting stability and for the purpose of securing stability transverse to the direction of travel. Depending on the size of the luggage, this significantly widens the vehicle and can be disadvantageous for driving through pedestrian areas, for example, where the vehicle has a relatively narrow base.

[0016] The invention is directed to further developing a known type of rolling cart in such a way that it has a universal luggage rack which can accommodate different items of passengers, such as suitcases or shopping bags, wherein the rolling cart should be designed to be stable and compact with the lowest possible dead weight.

[0017] The closest prior art to this is found in WO 02 / 12057 A1. This document already shows a single-track vehicle on which people can be transported standing up. However, the frame here has more of a shell function, which only increases the stability of the vehicle in the folded state, but does not increase the stability of the vehicle in the unfolded state when driving. In this reference, the front wheel fork is also designed to be foldable and is not directly and fixedly connected to the frame. By means of a corresponding folding structure, as described, for example, in this reference, Figure 8 As shown in , it is not possible to transmit enough forces acting on the overall structure when driving. In this way, the guide column in this reference does not have a sufficiently strong connection with the frame. Summary of the invention

[0018] Starting from this prior art, the object of the present invention is therefore to further develop such a single-track vehicle in such a way that the stability during driving operation is significantly increased, so that the vehicle can also be used without concern by tall and heavy persons.

[0019] This object is achieved with the features of claim 1. Further advantageous embodiments are disclosed in the dependent claims.

[0020] Thus, in the case of using slightly different terms, the present invention provides a single-track vehicle on which a person can be transported while standing. The vehicle has: a steerable front wheel with a holder in the form of a front fork; a handlebar component by which a person can steer the vehicle; at least one rear wheel having a rear wheel receptacle; a steering column; a foot placement part arranged between the front wheel and the rear wheel; and a frame. The steering column connects the front fork and the handlebar component, and the handlebar component is fixedly connected to the steering column. The frame is constructed to extend along the driving direction. The foot placement part is arranged in the lower region of the rear part of the frame in the driving direction. The frame includes a vertical surface made of a rigid material, which extends in the longitudinal direction of the vehicle, and the vertical surface is arranged above the foot placement part between the steering column and the foot placement part in the longitudinal direction. The front fork is rotatably supported on the lower edge of the vertical surface, and the steering column is rotatably supported on the upper edge of the vertical surface. The foot placement part is connected to the region of the lower rear part of the surface. In order to limit the vehicle length and move the center of gravity backward, and for reasons of stability, the distance of the receiving point of the foot placement part on the frame is maximized. The frame preferably covers the foot placement part, so that the driver's feet are also positioned below the frame.

[0021] Here, the surface can be geometrically implemented so densely and the surface structure on the surface can be implemented so stably that a luggage piece can be fastened thereto without falling in the horizontal direction.

[0022] Also preferably, fixing possibilities are arranged at least at two positions of the surface, by which a luggage piece can be fastened.

[0023] When larger and heavier luggage pieces should be transported, preferably the surface is sealed at its lower end by a bottom platform extending horizontally to the side.

[0024] Preferably, braces are provided at the lower rear corners of the surface.

[0025] In order to further reduce the space requirement of the vehicle according to the present invention during transportation or storage, preferably, the foot placement part and the rear wheel are constructed to be removable together, and fastening devices are provided on the surface for vertically installing the foot placement part parallel to the lower edge of the surface when the rear wheel is downward.

[0026] In order to further facilitate the transportation of the vehicle according to the present invention, preferably, a horizontally oriented holding device, a stable handle or a holding loop is provided on the upper edge of the surface.

[0027] To further improve the stability of the vehicle according to the present invention, it is preferable that a beam is arranged between the outer corner portion of the bottom platform and the upper end portions of the side edges of the front and rear portions of the surface.

[0028] Preferably, a holder for a mobile phone or a card or a bottle holder can be provided on the upper edge of the surface.

[0029] Similarly, a closable compartment can be arranged on the surface to further improve the comfort for the user.

[0030] If the vehicle has an electric drive device, a storage battery can be fastened on the surface.

[0031] In addition, an advertising image and / or advertising text can be applied on one or both sides of the surface, and the advertising image and / or advertising text thus has particular prominence because they are displayed everywhere through the running of the vehicle according to the present invention. Description of the Drawings

[0032] In the following, the present invention will be explained in more detail by means of the embodiments shown in the attached drawings. Shown:

[0041] Figure 9 The guide post receiving part according to the present invention is shown in a 3D view. Detailed implementation manners

[0042] The present invention provides a roller cart for transporting personnel and luggage, such as a roller cart based on physical strength (pedal roller cart) or an electrically driven roller cart (electric scooter) in an implementation manner.

[0043] Basically, the present invention studies two problems: on the one hand, the roller cart should have a universal luggage rack so as to fasten different utensils of a passenger, such as a box or a shopping bag, to the luggage rack, and the utensils can be poorly or not at all transported on the back of the passenger as a backpack.

[0044] On the other hand, a stable and compact structure is provided with as small a self-weight as possible, and the structure makes the roller cart itself as portable as possible and still can withstand increased forces, especially the driving dynamics forces along the driving direction.

[0045] This is solved by observing a long and three-dimensional frame 1 in the driving direction, and the frame receives the forces of the foot placement part 2, the front wheel 3, and the guide column 12 and integrates a luggage carrier.

[0046] Figure 1 The prior art of a pedal roller cart or an electrically operated electric scooter without a luggage carrier or a luggage container is schematically shown. The components according to the present invention projected into Figure 1 are shown in dashed lines. Figure 2 And the subsequent figures only show the roller cart of the design according to the present invention.

[0047] In Figure 1 the roller cart according to the prior art shown includes the following components:

[0048] A front wheel fork 6, and the front wheel fork is rotatably held together with a guide column 8 by means of a substantially vertically oriented tube 3a at the front part of the frame 1, and the frame extends in the driving direction and sequentially bears a foot placement part 12 and a rear wheel 9 front and back.

[0049] The front wheel fork 6 vertically receives the front wheel below and is sealed at the upper side by a guide tube end. In a traditional roller cart, the front wheel fork is received from below by a substantially vertically oriented tube 3a as an externally surrounding sleeve-shaped guide support part, and the guide support part is also connected to the guide column 12 above.

[0050] This guide support part is usually connected to the foot placement part 12 via a cross beam 5, and the beam 5 is usually bent and welded at the connection part with the front wheel and the guide column receiving part 3a and at the connection part with the foot placement part 2.

[0051] In a pedal roller driven by muscle power, the beam 5 is usually interrupted between points 7a and 7b by pivot bearings so that the guide column 12 together with the front wheel 6 and the foot placement part 2 together with the rear wheel 9 can pivot relative to each other, so that the roller can thus be carried and stored better in the folded state. In order to fix the pivot angle (derived from the end points 8 and 9) in the driving state and in the folded state, movable parts are used, such as locking bolts, which have corresponding clearances.

[0052] Such clearances are especially perceptible to the driver due to the relatively long lever of the guide column.

[0053] This is caused by the upright position of the driver, which also requires a certain length for the foot placement part and / or the wheel support part to ensure the tilting stability about an axis transverse to the driving direction.

[0054] Due to the weight of the driver (the vertical arrow shows the main force direction) and when pulling and pressing open the guide column 12 for acceleration and braking ( Figure 1 the horizontal arrow in shows the main force direction), relatively large forces occur at points 7b and 7a and between them - especially for taller and heavier people.

[0055] This lever force is also dynamically strengthened by the ground unevenness and acts as a bending force and a shear force on the material, which requires high material strength and stable, expensively manufactured connections (welded joints). The possible pivot bearings with fixing bolts and their receiving parts must also have a stable structural form. All these will contribute to the increase in the cost and weight of the roller.

[0056] In the frame 1 according to the invention, the area of the plane opened between the force-receiving points 4 and 10b through points 8, 6, 9 is supported by a filled, planar structure, which is also called the load-bearing part 13, so that the thrust and pull (the inclined arrows) act mostly on this structure.

[0057] In addition, the lever length is shortened and thus the lever force is reduced. Therefore, the forces acting in the horizontal direction in the driving direction and against the driving direction act on the guide column receiving part 4 according to the invention only on the lever path 8 - 4 via the guide column 12. In contrast, in the prior art, the same forces act on the lever path 8 - 11.

[0058] The vertical force component acts on the path 10b - 9 according to the invention and on the path 7b - 9 according to the prior art.

[0059] In addition, the counter lever against the lever force is extended. According to the prior art, this is limited to the width of the beam 5 at point 7a or 7b.

[0060] According to the present invention, the counter lever (horizontal force) acting on the guide post 12 is the distance 3b - 4, and the counter lever (vertical force) acting on the foot placement part 2 and the rear wheel 9 is the distance 10a - 10b.

[0061] The shortening of the lever length and the extension of the counter lever both reduce the load on the receiving part and the frame member, so that the receiving part and the frame member can be implemented more lightly.

[0062] DE112016006507T5 and CN108791621A also propose to fill this angle with a hollow body. However, the driver's feet are positioned on the side of the hollow body and not behind the hollow body. Therefore, it is impossible to provide a luggage placement part on the hollow body, or the luggage placement part on the hollow body is disadvantageous.

[0063] In DE20018919U1, the guide post is received by a three-dimensional container, but the sensitive beam 5 is retained.

[0064] Although the roller cart device manufactured around a box (such as DE000010204478A1, DE202019103766U1, DE000008128047U1) also benefits from this central frame with a shortened lever, it is oriented transversely to the driving direction, while the strongest driving dynamics forces act along the driving direction.

[0065] The embodiment of the frame 1 can be realized in the form of a tubular truss frame or as a monocoque.

[0066] A possible implementation is a long tubular frame, similar to a bicycle frame. The gaps between the tubes can be covered with material for transporting small pieces of luggage, for example.

[0067] According to the present invention, a planar three-dimensional volume body is used as the frame 1. The volume body is preferably additionally strengthened at the lower edges and in the regions of the receiving parts 3b, 10a, 10b, 4 and is at least closed on the side. Drawers or compartments can be provided on the upper and lower sides for storing valuables or placing a battery in the case of an electric scooter.

[0068] The frame 1 includes a load-bearing member 13 made of a rigid material. The load-bearing member has a vertical surface, which can also be simply referred to as a "surface". The load-bearing member serves as a vertical luggage surface on at least one side. Compared with a tubular frame, the luggage surface has the most flexible fastening possibilities, for example, in the form of fixedly installed hooks 17, eyelets or cutouts for inserting various holding members.

[0069] As Figure 4 shown, the loading possibility of the frame 1 with the vertical luggage surface of the load-bearing member 13 according to the present invention corresponds to a reduced truck flatbed rotated by 90 degrees.

[0070] Similar to a truck - loading flatbed that becomes a container with a tarpaulin frame and a tarpaulin, in a further embodiment of the present invention, various accessories and coverings can be utilized, for example, to become an enclosed container for luggage through clampable frame members and material members.

[0071] Similarly, the luggage surface can be permanently connected to luggage items, such as boxes.

[0072] Fastening elements, such as expanders, fixedly clamped on the outer edge of the luggage surface can be used to lock the luggage, or accessories can be hung into the voids in the surface, for example, to fasten solid luggage or install cross - grilles, or to fasten a bag or a box to the hook 17 through a collar.

[0073] According to the present invention, the lower region of the vertical luggage surface of the carrier 13 having a horizontal bottom platform 14 is preferably provided with a bottom shelf or a bottom plate - like member to lock the luggage downward.

[0074] Furthermore, when a load is placed on the vehicle, the center of gravity of the entire vehicle moves downward. With a lower center of gravity, it is easier to maintain balance during driving, and the roll stability increases.

[0075] Therefore, even with luggage, the roller cart can be stably parked upright by means of the outriggers.

[0076] The horizontal bottom platform 14 is preferably fixedly integrated in the frame 1.

[0077] If the roller cart is to be constructed relatively narrow, or if the size of the load varies greatly, the horizontal bottom platform 14 can be moved into the frame 1 in multiple levels in a further variant and removed for transportation, or folded onto the vertical luggage surface of the carrier 13 and unfolded for transportation.

[0078] Another removable or deployable horizontal loading surface can be installed above the horizontal bottom platform 14 in parallel.

[0079] For additional stability, according to the present invention, the vertical luggage surface of the carrier 13 and the horizontal bottom platform 14 are connected to the beam 15 at least at the outer edges in the front and in the rear, and the beam is preferably fixedly installed.

[0080] But this can also be implemented as removable, especially in the case of a movable bottom platform.

[0081] According to the invention, a horizontally oriented holding device, such as a stable handle or a holding collar 16, is mounted on the upper side of the frame 1 in order to lift the roller cart with one hand, for example in order to carry it above a walking staircase. The horizontal arrangement of the holding device according to the invention as close as possible to the center of gravity of the base surface makes it easier to keep the roller cart in an as horizontal as possible position.

[0082] A common problem with roller carts that cannot be folded together, especially electric roller carts, is the space requirement when parked.

[0083] In a variant of the invention ( Figure 6 ), the foot placement part 2 together with the rear wheels 9 can be removed from the frame 1 and is mounted downward on the rear side of the frame 1 together with the rear wheels 9.

[0084] Thereby, the base surface during parking is significantly reduced, and road dirt remains on the ground with the wheels. However, the roller cart can still be pushed and moved even in the folded state.

[0085] For this purpose, the receiving struts 10a, 10b of the foot placement part 2 on the frame 1 are provided with pull-out bolts 18a, 18b, which connect the lower sides of the receiving struts 10a, 10b to the foot placement part 2, and the foot placement part receives the pull-out bolts through drilled cylindrical hollow receiving parts 19a, 19b.

[0086] The fixing of the foot placement part 2 on the frame 1 is achieved by means of fittings or, according to the invention, by magnetic surfaces on the outer side of the rear beam 15 and the lower side of the foot placement part 2.

[0087] The lower side of the frame 1 is suitable in an embodiment according to the invention for mounting a deployable support, which can then also be used when the foot placement part 2 is folded up.

[0088] Figure 7 and 8 Shows the front wheel receiving part 3b according to the invention. The front wheel fork 6 leads into a rotatable vertical tube, which is surrounded by a stationary receiving block 22 (also referred to as "holder" 22) via a rotational bearing 21, and the receiving block is preferably installed as a separate component on the lower side of the frame 1 or is an integrated part of the frame.

[0089] Figure 9 Shows the guide column receiving part 4 according to the invention. The guide column 12 is preferably arranged aligned and concentrically above the front wheel fork 6 and is positively coupled to the front wheel fork. Alternatively, the guide column 12 can be arranged offset from the front wheel fork 6 and be connected to the front wheel fork via a drive device, such as a chain drive.

[0090] The guide post receiving part 4 is rotatably surrounded by the stationary receiving block 23 via the rotary bearing part 21a. The receiving block is preferably installed as a separate component on the upper side of the frame 1 or is an integrated part of the frame.

[0091] In a single-track vehicle having a frame (1), at least one rear wheel (9) is supported on the frame by means of a rear wheel receiving part of the frame (1), and a guide post (12) and a front fork (6) are supported on the frame by means of at least one receiving part (4; 22) having at least one rotary bearing part. The front fork has a front wheel receiving part (3b) for a front wheel (20) guided by the guide post (12), and the frame of the vehicle has a footrest part (2). A handle part (8) is provided on the guide post (12), and a person uses the handle part to guide the vehicle. The guide post (12) and the front fork (6) are directly or indirectly coupled to each other. The handle part (8) is fixedly connected to the guide post (12), and

[0092] The frame (1) is configured to extend along the traveling direction. The frame (1) includes at least one load-bearing member (13) made of a rigid material and having a vertical surface. The load-bearing member extends in the longitudinal direction of the vehicle, and the load-bearing member is arranged above the footrest part (2) in the region of the guide post (12) or between the guide post (12) and the footrest part (2). A front fork receiving part (22) for the front fork (6) is formed in the region of the lower edge of the load-bearing member (13), and a guide post receiving part (4) for the guide post (12) is formed in the region of the upper edge of the load-bearing member (13). The footrest part (2) extends further rearward than the load-bearing member (13) with respect to the traveling direction. The front fork receiving part (22) and the guide post receiving part (4) only allow rotational movement of the front fork (6) and the guide post (12) with respect to the frame (1), and the load-bearing member (13) receives the forces acting horizontally on the front fork (6) and the guide post (12). The footrest part (2) is connected to the rear lower region of the load-bearing member (13).
