Description

Field of invention

[0001] The invention relates to a fastening system for attaching an accessory to a bicycle. In particular, the invention relates to a fastening system for a water bottle. The invention further relates to an accessory equipped with the fastening system and to a bicycle. Background of the invention

[0002] Mounting systems for attaching accessories such as water bottles to a bicycle frame are known. For example, patent application WO 2018 / 041716 A1 discloses a mounting system for a water bottle. This system comprises two spaced-apart mushroom-shaped brackets on the frame. A water bottle with a holder can be attached to these brackets. Magnets attract the water bottle to the brackets. Once attached, the water bottle is also mechanically locked. To release the lock, the water bottle is rotated around an axis extending transversely through the bottle. The system allows for particularly easy attachment of the water bottle, especially while riding. However, removing the water bottle from the frame is not very intuitive. Object of the invention

[0003] In contrast, the invention is based on the objective of providing a simple and robust fastening system for attaching an accessory, in particular a water bottle, to a bicycle, which is simple and robust and can be used intuitively and comfortably. Summary of the invention

[0004] The object of the invention is already solved by a fastening system for attaching an accessory to a bicycle according to one of the independent claims.

[0005] Preferred embodiments and further developments of the invention can be found in the subject matter of the dependent claims, the description and the drawings.

[0006] The invention relates to a fastening system for attaching an accessory, in particular a water bottle, to a bicycle. The fastening system comprises at least two mushroom-shaped mounting brackets that can be attached to the frame. A holder, which includes at least two sockets, can be attached to and locked onto the mounting brackets. The holder is attracted to the mounting brackets by magnetic attraction, and in the attached and locked position, the mounting brackets engage in the sockets. First locking bars, connected to an actuating element designed as a slider, engage under the mounting brackets, and second locking bars engage under the mounting brackets opposite the first locking bars. The second locking bars are each coupled to the slider via a rocker arm. When the actuating element is actuated, the second locking bars move in the opposite direction to the first locking bars.

[0007] The basic principle of the invention is therefore based on the fact that the holder comprises latches which engage under a mushroom-shaped head from two opposite sides, particularly from the transverse sides during intended use. One latch is coupled to the actuating element, which is designed as a slider, and is linearly displaced when the actuating element is pressed, so that it moves under the mushroom-shaped head and releases the locking mechanism. The opposite latch is moved in the opposite direction by a rocker arm that is coupled to the slider. In this way, the system can easily lock under a mushroom-shaped head from both sides. The system is thus easily secured against the accessory falling off, even under significant vibrations.

[0008] Furthermore, the accessory is drawn towards the frame by magnetic means during attachment, which allows for particularly easy installation. Preferably, magnetic means, especially magnets, are integrated into the mushroom-shaped heads and the holder.

[0009] The latches and / or mushroom heads preferably include a ramp so that the latches automatically extend when the accessory is attached and snap into place under the mushroom heads.

[0010] The slider preferably comprises a holder, in particular a lever-like design, which projects transversely from an opening in the side wall, in particular the longitudinal side of the side wall.

[0011] When removing the accessory, it can be grasped and the actuating section pressed to release the lock.

[0012] The accessory is removed in the opposite direction to its attachment, namely in the form of a linear movement in the direction of the central axis of the mushroom heads.

[0013] The system thus provides a simple and intuitive way to attach and remove the accessory.

[0014] In a further development of the invention, the slider is moved into the locked state by means of magnetic attraction.

[0015] Therefore, no spring is provided to pre-tension the slide into the locked state; instead, the slide is held in the locked basic state by means of magnetic force.

[0016] In particular, the slider may include magnetic means, especially magnets, which interact with the magnetic means of the mushroom heads and / or the holder.

[0017] Compared to the use of springs, this results in a particularly simple and robust design of the fastening system.

[0018] In one embodiment of the invention, the slider comprises a frame-shaped inner part that is transversely movable in the housing and which comprises the first latches, each of which engages in an internal socket that forms the bushing.

[0019] The sliding frame can be rectangular in shape and occupy the majority of the housing. The sliding frame, together with the actuating section, can be manufactured as a single injection-molded plastic part.

[0020] Linear displacement across the housing can be provided, for example, via a rail system.

[0021] Furthermore, the inner frame may include magnetic means, in particular magnets, which move the slider into the locked home position.

[0022] Using such a frame allows for a simple and compact design.

[0023] The internal slots include through-openings for the bolts. Magnetic elements are preferably also located in the slots. In particular, the slots can have a radially extending partition that divides the slot into a chamber for receiving a magnetic element and a receiving section for a mushroom-shaped head.

[0024] In one embodiment of the invention, the rocker arms each comprise a head which is received in a recess of the slider. The recess can, in particular, be located on the inside of the inner frame.

[0025] The rocker arms are preferably mounted on axles formed by a housing part of the holder. This allows for a particularly simple and robust design.

[0026] To assemble the holder, only a housing and the sliding actuator are required. The mounting system can thus be provided with just a few components.

[0027] According to a further aspect, the invention relates to a fastening system for attaching an accessory, in particular as described above. The fastening system comprises at least two fastening heads, in particular mushroom heads, which can be attached to the frame, wherein a holder, comprising at least two bushings, can be attached to and locked onto the fastening heads. In an attached and locked state, the fastening heads engage in the bushings, wherein first locking bolts, which are connected to an actuating element designed as a slide, engage under the fastening heads, and second locking bolts engage under the fastening heads opposite the first locking bolts. The second locking bolts are each coupled to the slide via a rocker arm, such that when the actuating element is actuated, the second locking bolts move in a direction opposite to that of the first locking bolts.

[0028] The invention further relates to a fastening system, which can in particular be designed as above, comprising at least two fastening heads, in particular mushroom heads, which can be attached to the frame, wherein a holder, which comprises at least two bushings, can be attached to and locked onto the fastening heads, wherein the fastening heads engage in the bushings in an attached and locked state, and wherein the bushings have a larger inner diameter in the longitudinal direction than in the transverse direction.

[0029] The bushings are designed in particular as elongated holes.

[0030] In particular, the bushings have a diameter 0.3 to 3 mm, preferably 0.5 to 1.5 mm larger in the longitudinal direction than in the transverse direction.

[0031] It has been found that this is a simple way to compensate for manufacturing tolerances, especially positional tolerances of the mounting heads on the frame.

[0032] The invention further relates to an accessory comprising the holder for the fastening system described above. The accessory can, in particular, be designed as a drinking bottle.

[0033] The invention further relates to a bicycle, which may in particular also include an electric auxiliary motor, and which is equipped with the fastening system described above. Brief description of the drawings

[0034] The subject matter of the invention will below be described in relation to a drawing. Fig. 1 to Fig. The illustrated embodiment 6 will be explained in more detail. Fig. Figure 1 is a perspective view of a fastening system according to the invention. Fig. Figure 2 is a perspective view of the underside of the holder. Fig. Figure 3 shows the holder with the top of the housing removed. Fig. Figure 4 is a perspective exploded view of the components of the holder's locking mechanism. Fig. Figure 5 is a perspective view of the actuating element designed as a slide. Fig. Figure 6 is a longitudinal section through the fastening system in the area of ​​a mushroom head. Detailed description of the drawings

[0035] Fig. Figure 1 shows an embodiment of a fastening system according to the invention in a perspective view.

[0036] The fastening system 1 comprises an elongated holder 20, which can be connected to an accessory, such as a water bottle.

[0037] The holder 20 comprises a housing 21, from the long side of which the actuating section of an actuating element 30 protrudes.

[0038] To attach the accessory, the accessory and its holder are placed onto the mushroom-shaped mounting heads 10. Magnetic attraction draws the holder 20 towards the mounting heads 10.

[0039] In this embodiment, the fastening heads 10 comprise a head 11. The head 11 includes a ramp 12 on its end face, which causes the bolts to automatically deflect when placed on the surface.

[0040] Below the head 11 is a circumferential groove 13 in which the bolts lock.

[0041] Towards the frame, a stepped base 14 adjoins the groove 13. This can improve the centering of the holder.

[0042] In this embodiment, the mushroom heads comprise 10 threads 15 for attachment to the bicycle frame.

[0043] The holder 20, which is locked onto the mushroom heads 10, can be easily removed by pressing the actuating element 30 and simultaneously pulling the holder 20 off in the opposite direction to how it was attached.

[0044] As in the perspective view according to Fig. Figure 2 shows the underside of the holder 20, the holder 20 comprises two sockets 22 into which the mushroom heads engage when connected.

[0045] The first bars 31, which are part of the actuating element 30, each engage under the head of a mushroom head.

[0046] In this embodiment, collars 23 extend section by section around the bushings 22. In the attached state, the collar 23 surrounds the base of a mushroom head, thus providing improved centering.

[0047] By pressing the actuating element 30, the first locking bars 31 move out of the way.

[0048] The bushings 22 are designed as elongated holes which have a larger inner diameter in the longitudinal direction than in the transverse direction. This allows positional tolerances of the mushroom heads on the frame to be easily compensated for.

[0049] Fig. Figure 3 is a perspective view of the holder 20, with one upper housing half removed.

[0050] The actuating element 30 is designed as a laterally displaceable slide and comprises an inner part 32, which is designed as a frame.

[0051] In this embodiment, the inner part 32 is essentially rectangular.

[0052] The inner part 32 encompasses the internal nozzles 26, which provide the socket.

[0053] The nozzles 26 are subdivided by a radially extending wall in such a way that a chamber 25 is arranged above the bushing in each case, into which magnetic means, in particular magnets, are inserted.

[0054] Magnetic means, in particular magnets 33, are inserted into the inner part 32, in particular into the frame of the inner part 30, which hold the slide 30 in the locked position shown here. The magnets 33 can interact in particular with the magnets inserted into the chambers 25.

[0055] Furthermore, the housing includes recesses 27 which, in conjunction with the inner part 32, form a rail system for laterally displacing the slide 30.

[0056] For this purpose, the frame of the inner part 32 in the area of ​​the magnets 33 is designed as a thickened section, which engages in the recess 27.

[0057] In addition to the first bolts which can be moved together with the slider 30, the fastening system includes second bolts which are operated via a rocker 40.

[0058] The rocker 40 includes a head 42 which engages in a recess of the inner part 32.

[0059] The rockers 40 are mounted on pins 24, which form the axles for the rockers 40.

[0060] The pins 24 are preferably an integral part of an injection-molded housing base.

[0061] When the actuating element 30 is actuated, the second bolts 41, which are part of the rockers 40, move in a direction opposite to the slide 30 and the first bolts.

[0062] The lever ratio of the rockers 40 is preferably designed such that the distance of movement when unlocking the bolts 41 essentially corresponds to the distance of movement of the bolts of the slide 30.

[0063] This allows for the provision of a system that consists of few parts, is robust and simply designed, and at the same time ensures a very secure hold of the holder 20 in the attached state.

[0064] Fig. Figure 4 is an exploded view of components of the locking mechanism.

[0065] The figure shows the inner part 32 with the magnets 33, which is frame-shaped and includes recesses 35 for receiving the heads 42 of the rockers 40.

[0066] The actuating element 30 comprises the lever-like actuating section 34, which extends laterally out of the housing 21.

[0067] To assemble the fastening system, the actuating element 30, designed as a slider 30, is first inserted into the housing 21.

[0068] The first latches of the slide 30 (see 31 in Fig. 5) can reach through side openings 29 of the nozzles 26.

[0069] Then the rockers 40 are placed on the pins 24.

[0070] The bars 41 of the rockers 40 can engage the openings 29 opposite the openings of the nozzle 26.

[0071] The bars 41 of the rocker arms, preferably also the bars of the slide 30, can be adapted section by section to the circular contour of the mushroom head.

[0072] At the end of the assembly, the housing 21 simply needs to be closed with a housing top.

[0073] Fig. Figure 5 is a perspective view of slider 30.

[0074] Opposite the actuating section 34, the frame-shaped inner part 32 includes the bolts 31 on the inside.

[0075] In this embodiment, these are each arranged in the area of ​​a magnet 33.

[0076] Fig. Figure 6 is a longitudinal section through the fastening system in the area of ​​a mushroom head 10. The locked state is shown.

[0077] The mushroom head 10 includes a magnet 16, which interacts with the magnet 28 inserted into the chamber 25 of the nozzle 26 and pulls the holder 20 against the mushroom head 10 when it is attached. The latches 31, 41, which have their own ramps 31a, 41a, automatically deflect at the ramps 12 and then engage under the head 11 of the mushroom head 10.

[0078] The inner part 32 is held in the locked state shown here due to the magnet 33, which is attracted by the magnet 16 and / or the magnet 28.

[0079] The collar 23 of the housing 21 surrounds the stepped base of the mushroom head 10.

[0080] When unlocked by pressing on the actuating section 34, the first locking bars 31 under the head 11 of the mushroom head 10 move outwards (to the right in this illustration).

[0081] At the same time, the bars 41, which are guided by the rocker arms, move in the opposite direction.

[0082] This releases the locking mechanism under the head 11 and allows the holder 20 to be easily removed.

[0083] The invention made it possible to provide a simple and robust fastening system for an accessory on a bicycle, which is also intuitive to use.
