Description

Brief description of the invention

[0001] The present invention relates to a support element for rollers for transporting loads, as well as to corresponding rollers and an associated method.

[0002] For transporting loads such as shopping bags, crates of drinks, suitcases, and similar items, cargo bikes are known from the prior art, where the load can be transported on a platform or box in front of the vehicle. In addition, various trailers and baskets are also known that can be attached to a bicycle or vehicle, with the attachment point—i.e., at the rear, side, front, or top of the vehicle—varying depending on the vehicle type.

[0003] The disadvantage of the existing transport options is that they cannot be attached to the increasingly common electric or non-electric scooters.

[0004] The object of the present invention is therefore to provide a means of transport for scooters that makes it possible to use electrically or non-electrically powered scooters as a means of transport.

[0005] The present invention therefore relates to a scooter with a support element, wherein the support element is designed such that it projects to one side of a footboard of the scooter and its width (B Roller ) increased. According to the invention, the support element (2) has a plate thickness between 2 mm and 30 mm, a length (L Auflage ) from 10 cm to 80 cm and a width (B Auflage ) from 20 cm to 100 cm. The support element is a flat component, preferably in the form of a rectangular plate, which is arranged on the footboard and extends the footboard of the scooter to one side, wherein the support element itself can be extended by at least one extension element.

[0006] In one embodiment, the support element and / or the extension element comprise at least one hole, a grid of holes, and / or an elongated hole through which the support element can be connected to the at least one extension element and / or the footboard of the scooter. In particular, both detachable and permanent connections can be used. The connections between the support element and the footboard of the scooter and / or the support element and at least one extension element preferably include at least one plug connection, a quick-release fastener, a screw connection, an adhesive connection, a soldered connection, a rivet connection, and / or a tie-down.In one aspect of the invention, the support element has at least two, preferably six, holes arranged in the support element such that they are located on a plane to the left and right of the scooter's footboard, and through which preferably at least one rope, cord, strap, belt, and / or elastic band can be threaded and guided below the footboard, so that the support element can be connected to the footboard. According to the invention, the support element also has on one longitudinal side (L. Auflage ) an angle profile through which the support element can be hooked into the footboard of the scooter to generate an alternative or additional support between the support element and the footboard of the scooter.

[0007] According to the invention, the support element and / or the at least one extension element are made of wood, metal, and / or plastic. They may further comprise an anti-slip coating, in particular in the form of an anti-slip slag, at least one rubber mat, and / or at least one anti-slip adhesive, to prevent the transported goods from slipping. The elements have a load-bearing capacity of up to 150 kg, preferably up to 100 kg, and particularly preferably up to 50 kg. To secure the load, the support element and / or the at least one connecting element comprises one or more securing elements, preferably in the form of holes, hooks, eyelets, and / or lashing rails.

[0008] The dimensions of the support element or the extension element are as follows: a) the support element comprises a length (L Auflage ) of, preferably 30 cm and a width (B Auflage ) preferably from 20 cm to 80 cm; b) the support element in combination with at least one extension element has a size of 30 cm x 40 cm (length (L) x width (W)) and the extension element has a size of 30 cm x 30 cm (L x W) to 30 cm x 50 cm (L x W); and c) The thickness of the support element and / or the at least one extension element is between 2 mm and 30 mm.

[0009] Depending on the size of the support element or support element together with extension element (transport element), at least one stabilizing element can be arranged below it to prevent the elements from bending and dragging on the ground under load. This stabilizing element preferably consists of rollers and / or wheels, which are preferably foldable. The stabilizing element, for example designed as an additional roller, serves as a support for directly transferring forces to the ground and establishing equilibrium, independent of the user's weight.

[0010] The support element is preferably movably arranged on the scooter or footboard and foldable. At least one hinge is preferably used for this purpose.

[0011] This problem is solved according to the invention by the scooter with the features of claim 1. Advantageous embodiments with expedient further developments of the invention are specified in the remaining claims.

[0012] The present invention relates to a roller (1) with a support element (2) for transporting loads and to corresponding rollers (1).

[0013] In the following, the articles “ein” and all derivatives thereof, as used here, should generally be understood as “ein / e / es or more”, unless otherwise specified or the singular form is evident from the context.

[0014] Where the terms “contains”, “has”, “possesses” and the like are used in the description or claims, these terms shall be understood in the same way as the terms “possessing” or “comprising”, i.e., not exhaustively, unless explicitly stated otherwise.

[0015] The term "load" or "loads" basically encompasses all possible goods, cargo and merchandise, such as toolboxes, luggage, crates of drinks, purchases, bulky and / or business goods, such as televisions, long items like boards, surfboards, furniture and other items, as well as mail and parcels.

[0016] The term "scooter" (1) is used in the present invention for non-electric and electric vehicles, in particular kick scooters or kick scooters. The latter two are, in particular, small, single-track vehicles that are propelled by muscle-based pedaling (pushing off) and / or an electric motor. Although conventional scooters (1) generally consist of two wheels, scooters (1) with more than two wheels can also be provided, for example, with two wheels located at the front and / or rear to increase the stability of the scooter (1). The scooter (1) comprises a ground-level footboard (7) which is arranged between the at least two wheels and allows at least one person to stand on it. In the front part of the scooter (1), a handlebar, preferably with grips, is arranged vertically to the footboard (7), which enables the steering of the scooter (1).In some embodiments, the handlebar can be foldable and / or formed from several telescoping tube sections, allowing the scooter (1) to be folded to a smaller size and / or making the handlebars (11) height-adjustable. The tube sections can be adjusted using quick-release fasteners, locking mechanisms, or similar devices. The footboard (7) can be connected to the handlebar directly or via connecting elements. When connecting elements are used in the front section between the footboard (7) and the handlebar, these elements can also include a folding mechanism that allows the handlebar to be folded towards the footboard (7), giving the scooter (1) a nearly flat shape and making it easier to transport. In some embodiments, a seat can also be provided in the rear section of the footboard (7) for a person to sit on.Furthermore, the scooter (1) may be equipped with at least one light, a bell, and a brake (10). Particularly in the case of electrically powered scooters (1), two independently functioning brakes (10) are preferably provided, one of the brakes (10) being located at the front and one at the rear. In the case of non-electrically powered scooters (1), a fender brake (10) may also be provided above the at least one rear wheel of the scooter, which, when pressed down, contacts the rear wheel and causes friction, thereby generating a braking effect, such as the following. Fig. 1 can be seen. The scooter (1) can in principle be made of any stable material, in particular wood, plastic and / or metal, such as aluminium and steel.

[0017] Again Fig. As can be seen from Figure 1, the scooter (1) according to the invention additionally comprises a flat, level component, preferably in the form of a rectangular plate, which is arranged on the footboard (7) and projects to one side of the scooter (1). However, the plate can also have any desired shape. This flat component is described below as the "support element" (2). Normally, scooters (1) have a foot-width footboard (7), which allows at least one foot to stand securely. In the case of e-scooters, the footboard is sometimes wider so that both feet of a person can fit side by side on it. As the Fig. As can be seen from Figure 2, the footboard (7) of the scooter (1) is extended to one side by the support element (2), so that at least when the scooter (1) is empty, an imbalance to one side is created. The support element (2) is preferably arranged to the left or right of the footboard (7), depending on the user.

[0018] On conventional non-electric scooters, the user stands on one leg and leans outwards to gain momentum with the other leg, resulting in an imbalance of forces. Assuming, for simplicity, that the standing leg and the leaning leg each represent approximately 50% of the body mass, this creates an off-center counterweight of about half the body mass relative to the footboard (7) of the scooter (1), which needs to be balanced. Consequently, a user weighing, for example, 70 kg would require a load of 35 kg to achieve equilibrium. However, preliminary tests indicate that for a comfortable ride with the support element (2), the latter, when loaded, should weigh approximately 25% of the user's body mass.With additional weight on the side of the support element (2), for example by one or more extension elements (3) or a load, at least one stabilizing element (6) in the form of a wheel or rollers has proven effective in correcting the imbalance and stabilizing the journey.

[0019] The off-center swinging motion of the user thus compensates for the imbalance created by the support element (2), as shown by the Fig. 3. The support element (2) can also be used as a storage surface for loads. This allows for easy placement and transport of the goods by means of rollers (1). With the aid of at least one additional stabilizing element, for example in the form of a wheel or a roller, not only can the weight of the load being transported be increased, but also the length of the support element (2) and / or the extension element (3) can be increased, as shown in the Fig. 4 and Fig. 5 can be seen.

[0020] In the Fig. Figure 6-10 shows that in one embodiment the support element (2) can also comprise several extension elements (3) or consist of several elements, so-called extension elements (3), such as two plates that can be connected to each other or are firmly connected.

[0021] The support element (2) and the extension element (3) are preferably made of rigid materials such as wood, metal, and / or PVC. If the support element (2) is fixed to the scooter (1) and is optionally intended for outdoor storage, weather-resistant materials such as metal and / or plastic are used according to the invention. Additionally, an anti-slip coating can be applied to the support element (2) and / or the at least one extension element (3). This coating is intended to improve the rider's stability and also reduce load slippage. The anti-slip coating can be, for example, an anti-slip slag, a rubber mat, and / or an anti-slip adhesive. However, the possibilities are not limited to the above list; other known anti-slip materials or coatings can also be used.

[0022] In another aspect of the invention, the support element (2) comprises at least one hole (4, 12) ( Fig. 6), a perforated grid ( Fig. 7) and / or slot ( Fig. 8), by means of which the support element (2) can be connected to the at least one extension element (3), the support element (2) can be attached to the roller (1) and / or can contribute to securing the load on the extension element (3) and / or the support element (2).

[0023] How the Fig. As can be seen from Figures 6-10, in a preferred embodiment, the support element (2) is designed such that it can be used alone or with an additional extension element (3), so that, with simple assembly, preferably smaller loads and goods up to 50 kg, preferably 15 kg, can be transported, or, after attaching the at least one further extension element (3) to the support element (2), loads of preferably up to 150 kg, particularly preferably 50 kg, can be transported. For this purpose, the support element (2), which is attached or is attached to the roller (1), is preferably designed such that it has at least one, particularly preferably four, holes (12) on the projecting side or transport side, which allow the extension element (3) to be connected to the support element (2).Preferred connections are screws with corresponding nuts (9) that pass through the holes (12) of the support element (2) and the extension element (3), connecting them together. However, other connections known in the prior art, such as plug connections, quick-release fasteners, or other types of connections that allow for a detachable connection of the at least two parts, can also be used. Tests showed that using four screws arranged in a rectangle, inserted into countersunk holes (12) with a diameter of 6.5 mm located in the edge region of the support element (2) and / or the extension element (3), resulted in a stable fastening and provided a secure means of transport.

[0024] In addition to the connecting holes (12) between the elements, support element (2) and extension element (3), the support element (2), which is arranged on the footboard (7) of the scooter (1), also preferably has at least two, and particularly preferably six, holes (4) that allow the support element (2) to be connected to the footboard (7) of the scooter (1). For this purpose, the at least two holes (4), such as the Fig. As can be seen from Figure 4, the holes (4) are preferably arranged on the support element (2) such that they are located on the same plane to the left and right of the footboard (7), allowing a rope, cord, strap, rubber band, or similar material to be threaded through them and guided underneath the footboard (7), thus connecting the support element (2) to the footboard (7). In particular, the holes (4) are spaced at a distance greater than the width of the scooter (B). Roller) arranged relative to each other (with respect to width). Due to the varying widths of the footboards (7) of the different scooter types, several holes (4) are preferably provided for footboards (7) of different widths, so that the support element (2) can be attached to different scooters (1).

[0025] In addition to securing the support element (2) to the footboard (7) of the scooter (1), in an alternative or additional embodiment the support element (2) can be connected to the scooter (1), in particular the footboard (7), preferably by frictional connection, for example by welding, riveting and / or gluing, so that a non-removable connection is created between the two parts. Furthermore, in a particularly preferred embodiment, the support element (2) can also be hooked, clamped and / or screwed to the footboard (7) of the scooter (1), so that a releasable frictional connection is created between the two. As the Fig. As can be seen from Figure 10, in one aspect of the invention, the support element (2) is hooked onto the edge of the footboard (7). Furthermore, it can be additionally screwed and / or strapped down to achieve greater stability of the fastening. For this reason, in one embodiment of the invention, the support element (2) has an angle profile (8) in the non-projecting area of ​​the support element (2) that is brought into contact with the footboard (7). This angle profile allows the footboard (7) to be inserted into the support element.

[0026] The advantage of the detachable connection between roller (1) and support element (2) is that the latter can be quickly and easily attached to any roller (1) and can be easily replaced if damaged.

[0027] In addition to the holes (4, 12) for attaching the support element (2) to the roller (1) or the elements to each other, one aspect of the invention also provides one or more securing elements in the support element (2) and / or the at least one connecting element. These may, for example, be holes (5) intended for lashing goods or loads. Alternatively or additionally to the lashing holes (5), hooks, eyelets and / or lashing rails, straps, which are preferably foldable, may also be provided on the support element (2) and / or the at least one extension element (3).

[0028] The support element (2) is preferably designed such that it can be attached to common non-electric and electric scooters (1). For this purpose, the support element (2) has a length (L) of 10 cm to 80 cm, particularly preferably 30 cm, and a width (B) of 20 cm to 100 cm, particularly preferably 20 cm to 80 cm. If a support element (2) is used with an extension element (3), the support element (2) preferably has a size of 30 cm x 40 cm (L x W) and the extension board has a size of 30 cm x 30 cm (L x W) to 30 cm x 50 cm (L x W). The larger the support element (2) or the combination of support element (2) and extension element (3), the more likely it is that at least one stabilizing element (6) in the form of a load roller, roller, and / or wheel may be provided below the support element (2) and / or the extension element (3) to increase stability and enable the safe transport of loads and goods, such as the Fig. The stabilizing elements (6) in the form of load rollers, casters and / or wheels are preferably arranged below the support element (2) and / or the extension element (3) in such a way that they are only used when needed, i.e., that they are foldable on the underside.

[0029] Tests showed that the thickness of the support element (2) and / or the extension element (3) should be in the range of 2 mm to 30 mm, with a 4 mm thick metal plate, preferably made of steel or aluminum, proving optimal for transporting heavier loads. However, a thinner plate can be used with metal, and a thicker one with plastic. Depending on the size of the support element (2), the extension elements (3), the plate thickness, the material, and / or the stabilizing elements (6), a load-bearing capacity of up to 150 kg, preferably up to 100 kg, and particularly preferably up to 50 kg can be achieved.

[0030] In another aspect where the support board is firmly connected to the footboard (7) or the scooter (1), it can preferably be provided that the support board is movably arranged on the scooter (1), for example by means of a hinge, so that the space required when parking the scooters (1) is reduced.

[0031] Since both the support element (2) and the support element (2) with extension are designed such that they can be detachably attached to the footboards (7) of any non-electric and electric scooters (1), a support element (2) alone, as well as a transport element comprising support element (2) and extension element (3), can be used, in particular for transporting loads and goods. The support element (2) is designed such that it can be arranged on the footboard (7) of the scooter (1) with the center of gravity of the footboard directed to one side. The support element can have the embodiments already described for the scooter (1) with support element (2), with the exception that a non-detachable connection between the footboard (7) and the support element (2) is excluded here.

[0032] Although the support element (2) and the extension element (3) are described as plate-shaped, they may have one or more edges on the support surface to facilitate the transport of loads. Furthermore, the elements (2, 3) may also be designed as baskets. Alternatively, it may be provided that corresponding additional units, such as baskets, borders, brackets, grids, or similar units, can be attached to or are attached to the support element and / or the at least one extension element (3).

[0033] The present invention enables faster and easier transport of goods and loads without the need for other vehicles such as cars or similar vehicles. Consequently, even people of limited physical strength can use the support element (2) with or without extension elements (3) for private and commercial transport. In particular, the space-saving rollers (1) are also suitable for transporting loads or goods in city centers, factories, private hallways, exhibition grounds, and / or basements – i.e., in locations where larger cargo scooters, cars, or similar vehicles cannot be used, or not without considerable effort.Furthermore, using the scooters (1) with a support element (2) or the support element (2) on existing scooters (1) is very environmentally friendly, as transporting crates of beverages or other purchases can be done easily and quickly without having to rely on vehicles powered by fossil fuels. However, the scooters (1) with support element (2) can also be considered a supplement to a car, as they fit in the trunk and thus allow destinations with loads to be reached that cannot or may not be accessed by car. Areas of application would include, for example, deliveries in pedestrian zones, beach vacations, and campsites where transporting luggage has previously been a physically demanding task. However, the areas of application are not limited to the above list. For rough terrain, pneumatic tires and / or stabilizing elements (6) can also be used.

[0034] Although the intention is to place on the market a support element (2), a transport element and / or an extension element (3) that can be attached to existing scooters (1), it is also intended to provide a scooter (1) that includes a corresponding support element (2) or transport element. These are preferably to be made available at central locations, such as airports, exhibition grounds, railway stations, and city centers, but not limited to the aforementioned list.

[0035] The disadvantage of existing electric scooter rental systems (1) is that they lack central collection points, resulting in the scooters (1) being scattered everywhere and blocking pathways. Furthermore, charging them is difficult, as the scooters (1) sometimes have to be collected daily by the providers for charging. Besides the messy cityscape, the scattered scooters (1) pose a traffic hazard and, due to the need for vehicle collection, are also environmentally unfriendly.

[0036] Therefore, the present invention also relates to a station in which the scooters (1) can be stored neatly and securely with support elements (2), wherein the scooters (1) can preferably be pushed together, similar to shopping carts. Furthermore, a security and deposit system is provided, which, for example, uses locking chains to allow the release of the scooter (1) via a coin system, app-based release, or similar means. In addition, it is provided that the scooters (1) can only be returned if they have been reattached to the security system. This technology ensures that the scooters (1) are not scattered everywhere, but that anyone can take a scooter (1) as needed and carry out their intended purpose.

[0037] These and other embodiments of the present invention are disclosed in and encompassed by the description and examples. Further literature on known materials, processes, and applications that can be used in accordance with the present invention can be accessed from public libraries and databases, for example, using electronic devices. A more complete understanding of the invention can be obtained by referring to the figures, which are provided for illustrative purposes and are not intended to limit the scope of the invention.
