Abstract
Description
Technical field:
[0001] The invention relates to a bicycle saddle bag with integrated carrying straps. State of the art:
[0002] Document US4491258A describes a pannier that can be mounted on a bicycle and, when unmounted, can be converted into a backpack. This invention differs from the present invention in that the bicycle itself is not carried by the bag.
[0003] Publication DE20201406773U1 describes a bicycle backpack that can be worn while riding a bicycle. It is not suitable for transporting the bicycle itself. Purpose of the invention:
[0004] The invention aims to provide a way to carry a means of transport, e.g. a bicycle, without requiring additional conversions or disassembly of the bicycle. Description
[0005] The present invention relates to a bag, in particular a bicycle saddlebag, which is equipped with integrated carrying straps for carrying a bicycle or means of personal transport as a backpack on the back of a person.
[0006] Saddlebags that attach to the seatpost or the saddle itself, underneath the saddle of a bicycle, are widely available on the market. These saddlebags can also be attached to the vertical handlebars of scooters or similar means of transport. They differ in their mounting mechanisms and functionality regarding storage capacity, shape, and use.
[0007] Smaller means of transport, such as children's bicycles or kick scooters, are often carried with one hand.
[0008] The disadvantage of a carrying device integrated into a separate backpack is that the backpack must always be available to carry the bicycle. This is particularly relevant for children's bicycles, which typically don't need to be transported in a backpack on longer trips, yet are often carried.
[0009] According to the invention, a combination of saddlebag and backpack is provided that solves these problems.
[0010] The idea of the present invention is to provide a carrying function in a saddlebag that is attached to the bicycle and always available. It avoids the disadvantage of needing to carry a separate backpack or shoulder strap and offers the advantage of keeping the hands free while carrying. This is particularly important for smaller bicycles, such as those used by children, as the child and other items also need to be carried.
[0011] According to the invention, the saddlebag needs to be attached to the bicycle, ideally below the saddle. A mechanical connection can be made by screwing, mechanical linking and / or locking the bag to the bicycle.
[0012] The saddlebag includes at least one carrying strap integrated within the bag's volume. These straps are wound onto one or more spools, preferably arranged side by side, and can be tensioned by one or more return springs. A locking mechanism on the spool(s) can counteract the return spring and prevent the strap from unwinding. This locking mechanism can be secured against displacement by a spring.
[0013] The saddlebag has a cylindrical shape to accommodate at least one coil that can rotate around its longitudinal axis. The material is dimensionally stable and robust. Light sources for traffic safety or fluorescent material can be integrated into one of the compartments.
[0014] When the lock is released, each spool with its carrying strap wound up can be pulled out of the saddlebag. If no force is applied to the carrying strap, the return spring acts as the force and winds the strap up mechanically. The locking mechanism can be set to engage all spools or just one at a time.
[0015] At the end of each strap is an eyelet or fastening mechanism that allows the carrying strap to be attached, in particular, to the bicycle handlebars. When the carrying straps are extended, this creates a loop that can be slipped over the handlebars. In the simplest version, the strap can be pulled through the eyelet and the resulting loop pulled over each side of the handlebars. In another version, a mechanism can secure the strap to the handlebars. In yet another version, a Velcro fastener can secure the resulting loop.
[0016] The loops created by this process are used to pull the bicycle onto the back like a backpack, with at least one loop for a side carrying bag or with two loops for each arm.
[0017] The carrying strap can be readjusted if necessary using a dial on each side of the saddlebag. Turning the dial shortens the carrying strap without having to release the locking mechanism. Drawings:
[0018] The invention is described in more detail below with reference to drawings, which show: Fig. 1. A view of the saddlebag with its essential components and features Fig. 2 A view of the saddlebag as an example, fixed to a child's bicycle including carrying straps.
[0019] In Fig. Figure 1 shows a schematic representation of the saddlebag (1). One side of the cylindrical saddlebag is shown open, containing the spool (2) without a wound-up strap. At least one spool (2) must be contained in the saddlebag to wind up one or more straps.
[0020] In Fig.Figure 2 shows the saddlebag (1) schematically with two straps (5). This design allows the bicycle to be carried on the back like a backpack.
[0021] The straps for the carrying device are guided outwards through one or more exit slots (11). The straps can either hang freely from the saddlebag without being fixed in place or be additionally secured to the saddlebag by a device or magnets. When mounted, the exit slots (13) face backwards in the direction of travel on the bicycle. Thus, they point upwards and allow for ergonomic strap positioning when the bicycle is secured to the back.
[0022] To prevent the straps from being pulled out of the saddlebag uncontrollably, a dial (3) with a locking mechanism (4) is attached to the saddlebag. This allows the straps to be tightened. When the locking mechanism is released, the strap can be pulled out of the saddlebag. Without tension on the strap, a return spring integrated into the locking mechanism (4) retracts it back into the saddlebag.
[0023] The entire saddlebag has a mounting point (12) to which a standardized attachment to the bicycle or means of transport can be made. In one version, this mounting point can also allow rotation around it to enable adjustment of the saddlebag's position. The mounting point is specifically designed for connecting the bag to a bicycle saddle.
[0024] Although the invention has been further illustrated and explained in detail by means of preferred embodiments, the invention is not limited by the disclosed examples, and other variations can be derived from them by a person skilled in the art without departing from the scope of protection of the invention. It is therefore clear that a multitude of possible variations exist. It is also clear that the embodiments mentioned as examples are truly only examples and are not to be understood in any way as limiting, for example, the scope of protection, the possible applications, or the configuration of the invention.Rather, the preceding description and the description of the figures enable the person skilled in the art to implement the exemplary embodiments in concrete terms, whereby the person skilled in the art, with knowledge of the disclosed inventive concept, can make various changes, for example with regard to the function or the arrangement of individual elements mentioned in an exemplary embodiment, without leaving the scope of protection defined by the claims and their legal equivalents, such as further explanations in the description.
