Description

[0001] The invention relates to a luggage carrier for a bicycle, such as a cargo bike and / or an electric (cargo) bike and / or a pedelec cargo bike, with a perforated sheet metal plate intended to be permanently fixed to a frame structure of the bicycle, preferably in the front or rear wheel area, for example by means of fastening elements that create a positive and / or force fit, such as rivets or screws, wherein the perforated sheet metal plate has a central part which is intended to be oriented substantially horizontally, wherein a plurality of holes are provided in the perforated sheet metal plate which are intended to receive retaining means and / or structures as a plug-in / locking system for the detachable attachment of, for example, panniers / loads and / or seats / racks / footboards and the like.Provided it is technically feasible and within the development process, the perforated sheet metal could in the future also be integrated into the frame structure of a bicycle / cargo bike / pedelec / e-(cargo) bike and thus be regarded as a bonded part of the bicycle.

[0002] Mounting kits are already known from the prior art. For example, EP 2 611 682 B1 discloses a mounting adapter for an electric bicycle. Such mounting kits are therefore situated in a different technical field and relate to mounting devices for an electric motor of a single-track or multi-track bicycle. An adapter for attaching the electric motor is provided, which can be fastened at least on one side of a bottom bracket tube and at least at one point on a down tube. The adapter has mounting holes through which it can be screwed to a receptacle on at least one side of the bottom bracket tube. A particularly noteworthy feature is that the adapter has at least one lateral support plate.which, in the installed state of the adapter, extends laterally from the bottom bracket tube along the down tube and has mounting holes at one end for attachment to the mount and at least one mounting point for attachment to the down tube at the other end, and, wherein the adapter has a second lateral support plate opposite the first lateral support plate, and, wherein the support plates have a hole pattern comprising at least one opposing pair of holes, consisting of a mounting hole in one support plate and a mounting hole in the other support plate, wherein the second lateral support plate, in the installed state, runs on the opposite side of the bottom bracket and down tube from the first support plate, and, wherein the adapter can be attached to the down tube with opposing screws passing through the pair of holes.

[0003] As is well known, conventional bicycles have a frame or frame structure made up of individual sections or tubes. These typically include a seat tube, a top tube, a head tube, a down tube, two chainstays, and two seat stays, as well as reinforcing tubes and / or struts often inserted between or extending from these tubes and / or stays. The fork, to which a steerable front wheel is attached, is also frequently considered part of the frame structure. The fact that such forks can be removed is irrelevant in this context.

[0004] Bicycle luggage carrier bridges are also known, as described, for example, in DE 100 28 127 C2. This patent describes a device for transporting large, bulky goods, such as crates of bottles. These devices work in conjunction with bicycle luggage carriers. The bicycle luggage carrier bridge has a perforated metal plate. A row of holes is located along the edge of the carrier bridge, into which a bungee cord, a single elastic strap, or similar item can be variably attached, depending on the item being transported. Especially in the area of ​​cargo bikes and e-bikes, the demand for safe, heavy-duty, modularly designed, and modularly loadable luggage carriers has increased significantly in recent times.Currently, there is no safe and adequate solution on the market for professionally securing and easily removing the necessary custom bag solutions on bicycles and e-bikes in the growing last-mile delivery / quick-commerce sector, thus failing to meet the demands of this still-emerging industry in terms of cargo volume and weight. In the future, such solutions, based on user-friendly yet secure plug-in / locking systems, should also be available in the B2C sector for all types of equipment needed by private customers.

[0005] Since the COVID-19 pandemic in 2020, the last-mile delivery market has fueled rapid growth for several multi-billion-dollar companies. Now, in this highly competitive market, efforts are focused on improving the reliability of equipment and increasing payload capacity. The aim is to develop a sustainable and robust quick-commerce concept, with payload capacity being a crucial factor for profitability. Postal service providers in metropolitan areas are also increasingly using bicycles / e-bikes to deliver goods.

[0006] While backpack delivery solutions for transporting goods, such as groceries, to customers via bicycle courier have proven successful in urban areas, this concept no longer meets current demands. Rapid growth has created legal requirements for many of the companies involved, leading to changes. Working conditions, equipment safety, and other factors appear to be making simple backpack deliveries questionable in the future, especially when profitability—defined as the number of goods delivered per employee per delivery and thus revenue—is the primary consideration.

[0007] It is becoming clear that, in addition to more ergonomic solutions, such as increasingly placing goods in boxes and bags on the bicycle instead of carrying them in backpacks, further improvements are needed. These boxes and bags can offer a larger volume, allowing multiple delivery points / customers to be visited simultaneously by a single driver, thus improving resource utilization and sales volume relative to personnel.

[0008] However, it has become apparent that the methods of stacking / loading various goods must be rapidly adaptable, and consequently, individual needs, requiring diverse payload options, also change just as quickly. It turns out that currently, neither suitable nor delivery-service-adapted e-bikes are available. This is crucial within this industry, as the equipment used is the most important prerequisite for the sustainable and robust concept presented here. Similarly, suitable and safe payload concepts are lacking to safely transport the increased volume and the associated payload weight on a two-wheeler, given the increased volume and need for flexible adaptation. This invention addresses these known disadvantages, aiming to eliminate or at least mitigate them.

[0009] The invention of a plug-in / locking system is realized in a luggage carrier of the generic type by the fact that the perforated sheet can have side parts integrally connected to the central part, which project transversely to the horizontal direction, preferably in the direction of gravity, or can also be used as the central part on their own. Integrally connected side parts are understood to be, in particular, side parts that are one-piece / made of one material and connected to the central part.

[0010] The clever design of the perforated sheet and the resulting highly resilient yet flexible concept behind it render conventional, unsustainable solutions relying on cable ties obsolete, as do the breakage-prone standard suspension solutions known from the state of the art.

[0011] Through the clever positioning of the holes for attaching counterparts to bags / boxes or other structures such as seats, footboards, railings, racks, scaffolding, or mounting systems—both in the center section and in both side sections (or exclusively in the center section or a single / exclusive side section)—a very stable and durable, yet modular and easy-to-load solution is provided. After a single demonstration of the plug-in system, anyone can operate it, regardless of the operator's / user's technical understanding and / or manual dexterity. This solution thus compares to, for example...The large number of couriers / messengers in quick commerce / last-mile delivery makes it easy to understand and enables time-efficient handling in everyday operations, whose loading and unloading process can be repeated as often as necessary without losing efficiency or having to use additional raw materials / resources for fastening.

[0012] Conventional, fragile hooks and adapters are unnecessary. Such conventional solutions typically have a maximum load capacity of 10 kg and are completely inadequate for a total payload requirement of 80 kg. Furthermore, the industry is increasingly requiring a total system weight of up to 200 kg (including total payload, bicycle weight, and rider weight) to achieve long-term profitability in individual quick-commerce concepts. Extensive testing has shown that existing solutions, both in terms of e-bike components and currently available payload solutions, are not robust or safe enough to meet these demands. Even reinforcing existing solutions by adding more hooks will ultimately lead to fatigue fractures that should be avoided.They are also not suitable for frequent (dis)assembly of loads / superstructures, as the plastic-like material is not designed for this frequent handling.

[0013] An innovative mounting kit, suitable even for loads up to 85 kg, is now being introduced, specifically designed for use with e-bikes. The perforated sheet metal system presented here, based on the invention, is known internally as the "Smart-Lock" mounting kit. The use of a perforated sheet metal as a plug-in / locking system on a two-wheeler for attaching various individual load options surpasses all currently known solutions on the market in terms of safety and handling. The principle behind the advantages of using a perforated sheet metal is therefore unique for two-wheelers. The modular design and the ability to attach various loads, such as bag systems, via interlocking counterparts make it highly advantageous for both small business customers and large companies with fleets of several thousand bicycles.In the context of bag solutions, it is possible to enhance a wide variety of individual bag designs by placing the corresponding counterparts / nubs, for example, on bag back panels or base plates. These counterparts / nubs can be easily, durably, and robustly integrated into the perforated sheet metal system and are modularly interchangeable. The principle behind this description can be applied to all conceivable mounting systems and is therefore suitable for both B2B and B2C sectors.The resulting secure connection leaves no room for incorrect assembly and is extremely easy to disassemble, both for the changing needs of the customer, even during operation and depending on the product, or for the short-term needs of a private individual (shopping, transporting children or pets, general transport options), as well as for service purposes. This ensures that in the event of a service call, our service mechanics have sufficient freedom of movement on the bicycle / pedelec to carry out necessary repairs, for example by quickly removing bags, boxes or other devices.

[0014] The newly achieved adaptation of a perforated sheet metal system for the core area of ​​bicycles / pedelecs makes it possible, for the first time, to attach a wide variety of bags to a single device, and in the future, a wide variety of mounting and securing systems, thus enabling the offering of attractive products for the B2C sector as well. This allows the combination of the pedelec as a suitable means of transport and a novel transport system to capitalize on the trend of delivery / logistics by bicycle / pedelec in urban areas and to increase the efficiency and profitability of companies by maximizing payload capacity.It appears that this will not only be a game-changer in the B2B sector, but will also influence the way in which locking mechanisms for various security systems are adopted in the B2C sector, and will provide a solution for the search for an all-rounder for various short-term uses in everyday life, so that in the future the use of a pedelec as the main vehicle for families in urban areas will be even more attractive if a wide variety of needs are met by one product.

[0015] Advantageous embodiments are claimed in the dependent claims and are explained in more detail below.

[0016] It is therefore advantageous if the holes are designed as through holes with the same or different cross-section / geometry / shape, or with other features such as conical shapes, or alternatively as perforations or embossing, but in any case with a conical shape to ensure a guided engagement of the anti-slip latch. This prevents incorrect assembly. A quickly deployable, modular, and 100% customizable system is thus provided. The primary functional objective here is to achieve a guided engagement of the anti-slip latch, whereby the latch should be actively released to guarantee secure fastening.

[0017] Furthermore, it has proven advantageous to have holes in the center section and both side sections. Of course, it's conceivable that only a single side section or just the center section is present. In any case, the holes ensure that multiple bags—currently, for example, five, six, seven, or even eight bags—can be attached to the rack. Configurations with eight or more bags are possible, tailored to individual customer needs. For instance, a customer might transport goods, such as groceries, in "containers" that are inserted into the bags. These containers are loaded into the bags and / or top boxes. One container per bag is intended. However, more containers per bag are also possible. Similarly, one container per top box is intended. However, more containers per top box are also possible. By using this system, the customer maximizes their sales volume per shipment.

[0018] Realistically, based on current development, available panniers can be attached to the bike rack as follows: a double top box or two small top boxes, positioned on the center section, and a double side bag or two small side bags, one on each side of the integrally connected side panels. With current pannier solutions, this allows for a maximum of four side bags and two top boxes. The overall volume does not change significantly with double the bag sizes, but it does allow for the transport of bulkier items. In the future, it will be possible to attach several smaller bags / mounts or even develop existing large-scale configurations, such as U-shaped boxes for specialized delivery services. This will maximize both the payload volume and weight, enabling more efficient delivery routes.

[0019] It is practical to design the holes so that they have two differently sized sections. The retaining device is inserted into the larger section and held / locked in the smaller section. However, it is also conceivable that in the future it will prove even more practical to replace the holes with cross-shaped, circular, angular, crescent-shaped, sickle-shaped, slot-shaped, elliptical, triangular, or trapezoidal recesses to securely fasten attachments.

[0020] For quick and secure assembly, it has proven effective if at least one of the holes has a conical shape, similar to a bottle's contour, where the neck area is narrower than the adjacent belly area. It is particularly advantageous if the neck area of ​​this bottle-shaped form is narrower at one end of the hole than the adjacent belly area at the other. This ensures a wobble-free fit of the counterpart / nub in the neck area, especially under the increased effects of gravity and / or braking force. Particularly secure designs can be created in this way. Alternatively, other shapes or various combinations thereof are also possible, such as cross-shaped, circular, angular, crescent-shaped, sickle-shaped, slit-shaped, elliptical, triangular, or trapezoidal shapes.

[0021] A particular embodiment is also characterized by the fact that the neck area has such a narrow width that a guide area of ​​a retaining element attached to the pocket side, namely the counterpart / nub, fits into the neck area (with as little play as possible), and a locking area of ​​the retaining element with a larger outer diameter than the guide area fits through the belly of the hole, but not through the neck of the hole. This ensures that while the retaining elements can be attached quickly and easily, self-detachment of the retaining element from the holes is prevented, even under extreme conditions such as impact and vibration.

[0022] If the outer diameter of the guide area of ​​the retaining device is smaller than both the width of the belly area of ​​the hole and the width of the neck area of ​​the hole, and the outer diameter of the retaining device is larger than the width of the neck area of ​​the hole but smaller than the width of the belly area of ​​the hole, then insertion is particularly simplified and wobbling and loosening of the retaining device in / out of the hole is particularly effectively prevented.

[0023] This makes a robust solution possible, even in large-scale production.

[0024] Furthermore, it has proven advantageous if the neck area of ​​the holes in the side pockets is located below, that is, facing downwards in the direction of gravity, the abdominal area.

[0025] It is also conceivable to integrate the mounting hardware directly into the bag, footboards, attachments, seats, railings, trailers, racks, mounting systems, and / or boxes, and then use it to attach the bags to the luggage carrier. Here, too, a form-fitting fastening principle is helpful. Locking mechanisms, such as those known from bayonet fittings, are also conceivable, as is the plug-in principle used in the aforementioned forms, which, when cleverly inserted, cannot detach themselves and can only be removed from the plug-in element by manual intervention.

[0026] An advantageous embodiment is further characterized by the fact that each side panel has two, four, six, or more holes. Ideally, at least one, but preferably at least two, three, or four holes should be provided for each bag to be attached. Tilting and unintentional loosening can be effectively prevented by this additional securing mechanism.

[0027] If there are at least two, four, eight or more holes in the middle section, a standardized solution can be used.

[0028] It has also proven advantageous to maintain a consistent distance between each pair of holes. This allows the pockets to be repositioned as needed and provides a modular design that can be customized by using multiple compatible load options.

[0029] An advantageous embodiment is further characterized in that the central part of the perforated sheet and the neck area of ​​the holes, viewed in the direction of travel of the bicycle, are arranged front to / proximal to the belly area of ​​the holes, or vice versa. The kinetic energy of the bicycle can then be used effectively to secure the bags to the perforated sheet. Alternatively, and depending on the future design, other placements of the holes in relation to the direction of travel are also possible.

[0030] If the central section has mounting holes for rivets, which are used to attach the luggage rack to the frame structure, such as a bicycle strut, a reinforcing tube, or a pipe, then a particularly ingenious design can be created. However, the design can also be equally ingenious if the perforated plate is to be considered an integral part of the frame in the future.

[0031] For quick bag changes and secure attachment of bags to the bicycle during transport, it has proven useful to have at least one safety recess for every two holes, preferably positioned between them, or at least one for each attached load (whether bags, boxes, footboards, seats, etc.). This recess should be located near the hole to accommodate at least one anti-slip latch per attached load. The section of the anti-slip latch that engages in the hole plate should have a square, elliptical, or round cross-section.

[0032] If the anti-slip latch is designed as a pin or bolt, particularly simple and efficient locking mechanisms can be used. Alternatively, handle, lever, crank, or button solutions are also conceivable for releasing the anti-slip latch.

[0033] It has proven advantageous if the outer geometries of the anti-slip bar are matched to the inner contour of the safety recess in such a way that movement of the pocket suspended in the holes in the side parts in the direction of gravity or against the direction of gravity is preferably excluded without play and / or movement of the pocket suspended in the holes of the middle part in the direction of travel and / or against the direction of travel is preferably excluded without play.

[0034] It has proven effective to arrange several safety recesses next to each other to allow for flexibility in pocket sizes by creating flexibility in the placement of the retaining devices.

[0035] It is also conceivable that the safety recesses are shaped like slits, crosses, circles, squares, crescents, sickles, elliptical, triangles or trapezoids, or like round holes, preferably as blind holes or through holes.

[0036] The intention is that the side panels or one side panel should protrude transversely / perpendicularly to the central panel, and in the case that two side panels are present, they should be arranged parallel or mirrored to each other.

[0037] If the side panels are folded, bent, or folded over, cost-effective, tool-free, and chip-free manufacturing steps can be used.

[0038] It has proven effective for the anti-slip bolt to be spring-loaded and designed to be movable in its longitudinal direction. Alternatively, it is conceivable in the future to replace the spring-loaded anti-slip bolt with robust, fixed counterparts that can be inserted into the opposite shape of the hole and follow the key-and-lock principle.

[0039] The invention also relates to a bicycle with a frame structure to which the luggage carrier of the type according to the invention is attached. However, the invention also relates to a bicycle without a luggage carrier designed according to the invention, but with at least one reinforcing tube projecting from a chainstay in the direction of a luggage carrier to be attached, wherein the reinforcing tube projects perpendicularly from the chainstay.

[0040] The design envisions several reinforcing tubes extending parallel to each other and all perpendicular to the chainstay in the direction of the luggage carrier to be attached or already attached, which can also be designed according to the invention. This results in a particularly rigid and durable frame design for a bicycle / pedelec / cargo bike.

[0041] The intention is that at least one bag, for example, should be detachably attached to the bicycle with a luggage rack. In this case, the bag typically has a honeycomb plate made of polypropylene or a similar plastic as its rear mounting point, through which the mounting elements / counterparts / feet / nubs engage. Alternatively, the mounting plates to which the mounting elements are attached can be made of other materials, provided that the material's durability is at least equivalent to the quality / load-bearing capacity of the current rear mounting points. Furthermore, on the side of the honeycomb plate facing the frame structure, there is often a spacer designed to act as a vibration damper, allowing it to rest against a chainstay.

[0042] The invention is explained in more detail below with the aid of a drawing. The drawing shows: Fig. 1 a first embodiment of a bicycle according to the invention, namely a pedelec / electrically powered cargo bicycle, with a first embodiment of a luggage carrier according to the invention in a perspective view, Fig. 2 of the luggage racks made of Fig. 1 in an unfolded configuration, Fig. 3 the folded luggage rack design made of Fig. 2 for attachment to the bicycle according to Fig. 1, Fig. 4 a perspective view of a section of the Fig. 1 to 3 of the luggage carrier shown with a bag attached to one of its side parts by means of retaining means, wherein the retaining means of the bag are mounted in a honeycomb plate made of PP, Fig. 5 the honeycomb plate of the Fig. 4 with an integrated anti-slip bar, Fig. 6 another embodiment of a bicycle according to the invention with a luggage carrier according to the invention attached to it, Fig. 7 a singular perspective representation of the holding devices of the bags, as they are in Fig. 4 are shown, and Fig. 8 a pocket-side counter plate for attachment to a central part of the luggage carrier according to the invention Fig. 1 to 4 and 6.

[0043] The figures are purely schematic and serve only to illustrate the invention. Identical elements are identified by the same reference numerals. Features of the individual embodiments are interchangeable or complementary.

[0044] In the Fig. Figure 1 shows a first embodiment of a luggage carrier 1 for a bicycle 2, namely a cargo bicycle, specifically an electric bicycle, i.e., a cargo bicycle / pedelec containing an electric motor. This bicycle 2 has a frame structure 3. The frame structure 3 has sections prepared to accommodate fastening means 4, namely rivets 5, for attaching the luggage carrier 1 to the frame structure 3. Screws can also be used instead of rivets 5. In principle, bonded solutions, such as welded solutions or solutions fully integrated into the frame, can also be used.

[0045] The luggage carrier 1 has a central section 6 which is essentially horizontally oriented, unless, for example, it is placed on a support plate of the frame structure in the front area of ​​the bicycle according to the invention in order to be used as a front carrier solution and would therefore have to be essentially vertically oriented. In the present embodiment, the central section 6 is aligned exactly horizontally in a plane. The central section 6 is designed as a perforated sheet 7 and has side parts 8 projecting at right angles on both longitudinal sides. The perforated sheet 7 has a plurality of holes 9. The holes 9 are designed as through holes and have a bottle-shaped contour 10. The components in the Fig. 4 holding means 11 shown, which are attached in a plate / honeycomb plate 12 of a transport bag 13.

[0046] The bottle-shaped form 10 of the holes 9 is particularly well suited to the Fig. 1 to 3 can be identified. The holes 9 have two sections, namely a neck area 14 and a belly area 15. The neck area 14 transitions into the belly area 15. The width of the neck area 14 is significantly smaller than the width of the belly area 15. The width of the neck area 14 is referenced by reference numeral 16, whereas the width of the belly area 15 is referenced by reference numeral 17.

[0047] In the Fig. 7 are those in Fig. Figure 4 shows the retaining means 11 attached to the plate 12 in a larger perspective view. The retaining means 11 have a base plate area 18 from which a guide area 19 projects axially, to which a locking area 20 is distally connected. The retaining means 11 has a central passage for a screw. The outer diameter of the base plate area 18 is larger than that of the locking area 20, which is larger than that of the guide area 19. The guide area 19 engages in the slot created by the hole 9, as shown in Figure 4. Fig. 4 is clearly visible, whereas the blocking area 20 is located on the inside of the luggage carrier 1 between the side parts 8. As shown in the Fig. 1, Fig. 2 and especially good in Fig. As can be seen in Figure 3, each side panel has at least one safety recess 21 into which a non-slip bar 22, as described in Figure 3, can be inserted. Fig. The anti-slip bar 22, as shown in Figure 5, engages. It can have a bolt that is pre-tensioned into its drive-on position and can be retracted by pulling an action section, or it can consist of a form that could be inserted into the form of the hole 9 as a counterpart.

[0048] As in the Fig. 1 and Fig. 6 clearly visible, the frame structure has 3 reinforcing tubes 24 projecting vertically from a chainstay 23.

[0049] For a pocket not shown, to be fixed on the middle part 6, a counter plate 25 can be used, as in Fig. Figure 8 shows how the bag is to be attached to the central section 6 of the luggage carrier 1, which is then to rest on that section. Recesses 26 may also be provided to facilitate attachment to the bag.
