Side supports for cycles, configured for permanently mounting on the cycle and for laterally supporting the cycle when stationary with or without a rider, or during riding, have at least one side stand mechanism (13) with at least one supporting wheel (13.9), which supporting wheel can be positioned in at least one height position. According to the invention, the side support device is switchable and has a gear device (14) which is coupled to the supporting wheel and is configured for positioning the supporting wheel in at least two height positions comprising at least one extended supporting height position and at least one retracted height position for support-free riding with the cycle. Robustness and flexibility can thereby be especially ensured. The invention also relates to the use of individual components of the side support device and to a method for coupling the side support device to a drive traction means of the cycle.

MORE DETAILED DESCRIPTION OF THE FIGURES

[0081] The invention will be described below with reference to all figures. Special features of the invention will then be indicated with reference to individual figures. Here, dashed or dotted lines schematically indicate individual components, for the sake of completeness or better clarity. For the purposes of better clarity, the individual components are, in individual figures, illustrated at least partially on their own, that is to say not as a complete assembly.

[0082] A bicycle 1 has a frame 1.1, a handlebar 2, a wheel pinion 3 at the rear wheel 4 with a mudguard 4.1, a luggage carrier 5, a saddle 6 and a wheel axle 7 with wheel screws 7.1. On the handlebar 2, there is provided a brake lever 8, into which an actuating device 20 (described in more detail further below) can be integrated. The wheel pinion 3 may be driven by means of a two-wheeled vehicle drive traction mechanism 9 in the form of a bicycle chain (drive chain).

[0083] A side support apparatus 10 has a housing device 11, configured for receiving the components described in more detail below, with longitudinal struts 11.1 and transverse struts 11.2, in particular in the form of square-section profiles, and with a rear lighting luminaire 11.9. The housing device 11 may be produced for example from aluminum or fiber composite.

[0084] On the bicycle frame 1.1 there is provided a support device 12 with four mounting points 12.1, 12.2, 12.3, 12.4 which are designed for receiving hollow profiles and which are in particular U-shaped. One or more longitudinal members 12.6 and transverse members 12.5 can ensure a high degree of torsional stiffness and a front-end support 12.51 on the bicycle 1. By means of posts 12.7 and struts 12.8 and axle receptacles 12.9, in particular slotted lugs, forces can be transmitted onward into the bicycle frame 1.1.

[0085] The side support apparatus 10 has two side stand mechanisms 13, specifically a left-hand side stand mechanism 13A and a right-hand side stand mechanism 13B, in each case with a (in particular T-shaped) stand mechanism arm 13.1 which is guided for example in guide rails, a cantilever 13.5 which interacts in positively locking fashion with a blocking mechanism, and multiple spring bolts or pressure bolts 13.6 (installed or mounted in particular on the cantilever), specifically a first and second spring bolt 13.6A, 13.6B, wherein, in the second spring bolt 13.6B, there is arranged a counterbore 13.61 around which a spring 13.62 is arranged. A linear toothing 13.7 with detent means in the form of a toothed rack permits latching in different height positions. The linear toothing 13.7 can be immobilized and unblocked by means of a ratchet fastener 13.72 in operative connection with one of the spring bolts 13.6B. The stand mechanism arm 13.1 is coupled by means of two springs 13.8, in particular tension springs, to the housing device 11. A support wheel 13.9 is connected by means of a vertical bearing support 13.73 to the stand mechanism arm 13.1. The linear toothing 13.7 may furthermore have a blocking means. The respective stand mechanism furthermore preferably has a receiving plate, a slide plate and a guide rail.

[0086] The side support apparatus 10 comprises a transmission device 14 with a transmission shaft 14.1, an engagement pinion 14.11 configured for engaging into a/the drive traction mechanism 9, a dome 14.2 (which dome may also be provided as a component of the traction mechanism kinematic system), a drive pinion 14.3 which is mounted rotationally conjointly on the transmission shaft 14.1 and which serves for transmitting a speed-increased or speed-reduced drive movement by means of at least one traction mechanism 14.4 to an output pinion 14.5, wherein the output pinion 14.5 or a further output pinion 14.6 (mounted in particular on the same shaft 14.8) is, by means of a traction mechanism 14.7, in operative connection with a drive pinion 16.6, which is mounted rotationally conjointly on a Bowden cable shaft 16.1. The Bowden cable shaft 16.1 may also be provided as a constituent part of the traction mechanism kinematic system 15. The further output pinion 14.6 may provide a further transmission ratio stage. The dome 14.2 may interact with one of the spring bolts 13.6A of the side stand mechanism 13, in particular by virtue of the spring bolt 13.6A exerting a pressure force on the dome 14.2 from above and thereby actuating the traction mechanism kinematic system described below.

[0087] The side support apparatus 10 furthermore comprises a traction mechanism kinematic system 15 with a first plate 15.1 and a second (lower) plate 15.2 mounted thereon by means of a pivot hinge 15.3 and in which there are provided multiple bores 15.21 and sleeves 15.22 for receiving pressure springs 15.23, such that the upper plate 15.1 can be spring-mounted relative to the lower plate 15.2. The sleeves permit guidance of the springs independently of the orientation of the upper plate 15.1. The sleeves also provide a receiving cavity for the springs in the case of the plates being fully closed and bearing against one another.

[0088] Several of the above-described components of the transmission device 14, in particular also the dome 14.2 and the transmission shaft 14.1, are mounted on the upper plate. Via the dome 14.2, it is thus possible for the transmission shaft 14.1 to be actuated indirectly by means of the spring bolt 13.6A. Multiple cables or chains 15.6, 15.61, 15.62, 15.63 of the traction mechanism kinematic system 15 are guided over a Bowden cable shaft 16.1 (described in more detail further below), wherein, in the case of each side stand mechanism 13A, 13B, in each case one cable 15.62, 15.63 is guided through the respective spring bolt 13.6B, such that the respective spring bolt 13.6B can be preloaded by means of the cable. For example, for this purpose, the cable is provided with a knot or a cable clamp at the free end below the spring bolt, such that the cable is fixable in an axially fixed manner to the spring bolt at least in one movement direction. The cables 15.6 can in this case ensure a link between the traction mechanism kinematic system 15 and the Bowden cable system 16 or the Bowden cable shaft 16.1. The cables 15.6 provide an output-side link, that is to say at the output side of the transmission device 14 or at the output side of the traction mechanism kinematic system 15, to the respective side stand mechanism 13A, 13B.

[0089] A spring-mounted triggering mechanism 15.8 in the form of a non-positively and positively locking holding clamp has a housing 15.81 and a spring element 15.82 and a bolt 15.83 with a bevel 15.84. A cable can be guided over a diverting rollers 15.87 in order to thus displace the bolt counter to the spring force and in order to thus permit a displacement of the respective support wheel into a particular height position or in order to prevent a displacement. Likewise, a spring-mounted triggering mechanism 15.9 in the form of a non-positively and positively locking spring clamp has a housing 15.91, a spring element 15.92 and a bolt 15.93 with a bevel 15.94, which bolt is likewise actuatable by means of a diverting roller 15.97 and a cable.

[0090] A Bowden cable trigger 15.5 which is integrable into or arrangeable adjacent to the brake lever 8 may in particular also be fixed, so as to be settable into different tension positions, by clamping means, in particular pointed screws.

[0091] The side support apparatus 10 furthermore comprises a Bowden cable system 16 for coupling multiple side stand mechanisms, wherein kinematic linking may be performed by means of a Bowden cable shaft 16.1 on which at least one idling roller 16.4 for guiding a cable is provided. The Bowden cable shaft 16.1 is linked by means of a drive pinion 16.6 to a drive pinion 14.5, 14.6 of the transmission device 14. The kinematic system may have one or more bearings for a kinematic link, in particular bearings for the Bowden cable shaft.

[0092] The side support apparatus 10 furthermore comprises an actuating device 20 with an actuating lever 21, in particular in the form of a brake lever or of a further lever coupled to the brake lever, and with a Bowden cable 23 with at least one individual cable 15.6, 23.1 and a connecting piece 23.4 or a distributor for splitting the individual cable 15.6, 23.1 into multiple cables or Bowden cables. By means of the Bowden cable 23, it is possible for further individual cables 23.2, 23.3 to be actuated, which are operatively connected to the clamps and/or triggering mechanisms 15.8, 15.9. The individual cable 23.2 may in this case correspond to the cable 15.61 guided over the Bowden cable shaft 16.1. The respective individual cable may be guided through a bore or guide in the inside of the respective bolt 15.93 and fixed thereto, for example by means of a clamping screw.

[0093] An actuation of the traction mechanism kinematic system 15 may be performed manually and/or at least partially by means of a drive 30, wherein the control device 40 can predefine the nature of the actuation or the time or the duration of an engagement, in particular on the basis of specifications from a data memory with regard to at least two different operating states or rider profiles.

[0094] The side support apparatus 10 extends transversely with respect to the direction of travel along a transverse axis x, and in the direction of travel along a longitudinal axis y, wherein the support wheels 13.9 are displaced in a z direction (vertical axis). The absolute dimensions of the side support apparatus 10 in the x direction may be described as track width. The track width lies for example in the region of 660 mm.

[0095] Special features of the invention will now be indicated below with reference to individual figures.

[0096] FIG. 1A shows the transmission device 14 in a plan view, wherein the individual components of the transmission device 14, which interact with traction mechanisms or cables and ensure movement linking, are arranged on the upper plate 15.1. It is possible to clearly see the dome 14.2 with an abutment surface 14.21 and with a pressure point 14.22 for the spring bolt 13.6A (FIGS. 1B and 1L).

[0097] FIG. 1B shows an arrangement of the traction mechanism kinematic system 15 in a blocked position, with engagement of the engagement pinion 14.11 from above into the bicycle chain 9. The holding bolt 15.93 blocks the upper plate 15.1 counter to the preload force of the spring 15.23.

[0098] FIGS. 1C and 1L show the transmission device 14 and the traction mechanism kinematic system 15 from a rear view, likewise in the blocked state, that is to say in engagement. The upper plate 15.1 has not been pivoted out upward.

[0099] FIG. 1D shows the arrangement of the transmission device 14 and of the traction mechanism kinematic system 15 in a housing device 11. It can be seen that only one transmission device 14 and only one traction mechanism kinematic system 15 are required on one side in order to be able to actuate side stand mechanisms on both sides. Movement linking of the two sides is realized by means of the shaft 16.1 shown in FIG. 2B.

[0100] FIGS. 1E and 1F show the arrangement of the transmission device 14 and of the traction mechanism kinematic system 15 in the housing device 11 relative to a drive traction mechanism 9 of the two-wheeled vehicle. The traction mechanism kinematic system 15 is arranged such that the transmission device 14 can be placed into engagement with the drive traction mechanism 9 from above. In this way, the engagement pinion 14.11 can engage into the loaded portion of the chain 9 (load strand). This also provides advantages with regard to compactness and weight/mass of the overall arrangement.

[0101] FIGS. 1G and 1H show the traction mechanism kinematic system 15 in the open state, without engagement. The pinion 14.11 has been displaced upward and is no longer situated in engagement with the chain 9. The two plates have been pivoted out by a switching angle in the range of 10 to 20 about the pivot bearing 15.3 and elastically preloaded relative to one another in this arrangement. Here, the upper plate abuts against a stop or a holding bracket 15.98. The corresponding pinion has, in this arrangement of the upper plate, been pivoted away from the bicycle chain, such that no engagement into the bicycle chain occurs.

[0102] FIGS. 1J, 1K, 1L show the traction mechanism kinematic system 15 in a closed state with plates bearing against one another, with engagement of the corresponding pinion 14.11 into the bicycle chain 9. The pinion is positioned on the chain, that is to say engages into the chain from above, in this case specifically in the loaded portion of the chain (load strand). No engagement takes place in the non-loaded portion (idle strand).

[0103] It can be seen in FIG. 1L that a pressure bolt 13.6A acts on the upper plate 15.1 from above and thereby closes the traction mechanism kinematic system. After the closure, a spring-mounted holding pin or bolt 15.93 acts on the upper plate and holds the latter closed until the holding pin is displaced out of the holding position counter to an elastic preload, in particular by actuation of a Bowden cable system by means of an actuating lever, whereby the corresponding cable 23.2 is pulled and the upper plate 15.1 is released in order to pivot back upward in a spring-driven manner. The pressure bolt is preferably composed of inelastic, non-deformable material.

[0104] FIG. 1M shows the nature of the interaction of the components of the triggering mechanism 15.9 which is actuatable by means of the Bowden cable. A spring-mounted holding pin 15.93 can be actuated by means of a cable 23.2 which is linked via a diverting roller 15.97 to a shaft or a Bowden cable. During the pivoting-closed of the two plates, that is to say during the actuation of the traction mechanism kinematic system by means of the pressure bolt 13.6A, the holding pin is pushed back counter to a spring preload and locks the plates as soon as these bear against one another. The holding pin can be pulled back into the open position by means of the cable for the opening or pivoting-back of the plates. The plates spring open, and the pinion is separated from the chain (unlinking).

[0105] FIG. 2A shows components of the transmission device 14 and of the side wall structure 13 in a plan view.

[0106] FIG. 2B shows the Bowden cable shaft 16.1 which links the two side stand mechanisms 13A, 13B to one another.

[0107] FIGS. 3A, 3B show the spring mounting of support wheel 13.9 and bearing support 13.73. The spring force of the springs 13.8 can be utilized to deploy the support wheels 13.9 in any traveling situation as far as the underlying surface, optionally also into different height positions in the case of an uneven underlying surface. FIG. 3B shows the kinematic system by means of spring bolts 13.6A, 13.6B. FIGS. 4A and 4B show the arrangement as in FIGS. 3A, 3B, in an opposite viewing direction.

[0108] FIG. 5A shows, as an individual component on its own, one of the two side stand mechanisms 13B with the linear toothing 13.7 formed on the bearing support 13.73. FIG. 5B additionally shows the nature of the engagement of the cantilever 13.5 with the triggering mechanism 15.8. FIG. 5C additionally shows the Bowden cable shaft 16.1 or individual pinions or rollers 16.4, 16.6. For the purposes of improved clarity, springs, traction mechanisms or cables or further components of the Bowden cable system are not illustrated.

[0109] FIGS. 5A to 5C and FIG. 7B show the functioning of the spring-mounted bolts 13.6A, 13.6B. The transmission pressure bolt 13.6A arranged above the transmission device 14 is arranged and configured to actuate the traction mechanism kinematic system 15 and thus indirectly also to switch the transmission device 14. The transmission pressure bolt 13.6A permits movement linking between side stand mechanism 13, traction mechanism kinematic system 15 and transmission device 14. The transmission device 14 can in this case be closed/locked by means of the bolt 15.93 with the engagement pinion 14.11 in engagement with the chain 9, such that the respective side stand mechanism can be preloaded counter to the spring force of the springs 13.8 into an upper, retracted height position.

[0110] The spring-mounted bearing support 13.73 of the respective side stand mechanism 13A, 13B is arranged and configured to compensate an unevenness of the underlying surface and thus to set an adequate height difference of the two side stand mechanisms 13A, 13B. Here, it is for example possible for a height difference of 5 cm per side to be compensated, as shown in FIG. 12. This also permits holding in an upright position on an inclined plane. The pressure bolt 13.6B in this case interacts with the linear toothing 13.7. The pressure bolt 13.6B (ratchet opening bolt) has, in particular, a spring travel in the range of 10 to 12 cm.

[0111] In this regard, it is possible here, by way of example, to describe three height positions at the linear toothing 13.7: in an upper position, the deployment travel of the corresponding side stand mechanism is lengthened, for example by 5 cm. In a middle position, the end position of the corresponding support wheel is brought into line with the height position of the bottom side (or of the ground contact point) of the rear wheel of the bicycle. In a lower position, the deployment travel of the corresponding side stand mechanism is shortened, for example by 5 cm.

[0112] FIG. 6 shows individual components of the support device 12, in an embodiment as a luggage carrier or as a device for installation at or above a luggage carrier. FIGS. 9A, 9B and 9C show one of several possible types of installation on a two-wheeled vehicle.

[0113] FIGS. 7A, 7B, 7C show details of the interaction of individual components for the movement linking.

[0114] FIG. 8 shows, by way of example, a Bowden cable with various cables, be it for transmitting an actuating movement onward to the clamps 15.8, 15.9 or for transmitting a setting movement onward to the respective side stand mechanism. The respective clamp 15.8, 15.9 may have a longitudinal bore and a lateral bore for the arrangement and relative guidance of the corresponding component.

[0115] FIG. 10 shows movement linking of an actuating device 20 and the triggering mechanisms 15.8, 15.9, wherein the guidance of the individual cables 23.1, 23.2, 23.3 may also be varied in accordance with the nature of the desired actuation, with further speed increase/speed reduction ratios or diversions.

[0116] FIG. 11A shows, in a rear view, an arrangement in an upper height position, without engagement. FIG. 11B shows the bicycle with deployed side stand mechanism 13, in the case of engagement of the traction mechanism kinematic system or of the transmission device into the bicycle chain 9, such that, now, when the bicycle chain 9 is driven, the support wheels 13.9 can, again in preloaded fashion counter to a spring force, be displaced into a desired upper retracted height position, in particular automatically when starting off. An upper stop edge of the pressure bolt 13.6B in this case interacts with the ratchet fastener 13.72 and releases the latter, that is to say unblocks the immobilized carrier 13.73.

[0117] If the stand mechanisms 13A, 13B are in a deployed state, then the bolt 13.6A of one stand mechanism 13B pushes the two transmission plates 15.1, 15.2 together. Here, the holding pin 15.93 is initially pushed back on the tip of the transmission plates. When the two plates have moved fully together, the holding pin 15.93 is abruptly driven forward by spring force of the spring element 15.82 and locks the two plates against one another. The contact pinion 14.11 now lies on the chain 9. As a result of the cranking of the pedals in the direction of travel, the chain moves the contact pinion, and the Bowden cable shaft 16.1 is driven via the transmission 14. The two cables 15.62, 15.63 of the stand wheels 13.9 now retract the stand wheels. This is a fully automatic process.

[0118] An unlinking from the bicycle chain 9 may take place as follows. The two stand mechanisms are at rest in a retracted, upper height position. By means of the Bowden cable trigger 15.5, a displacement downward (a deployment) can be triggered. If the Bowden cable shaft 16.1 now draws in the respective cable, the two stand mechanisms are pulled upward by a good 2 cm beyond the original height position. The further cable 15.61 or 23.2 is thereupon also tensioned, which further cable is connected to the holding pin of the transmission. The holding pin 15.93 is in this case pulled back such that the transmission springs open and the engagement pinion 14.11 is separated from the chain 9. The two stand mechanisms can thereupon fall back to their retracted height position again.

[0119] The spring 13.63 of the pressure bolt 13.6A is stronger than the springs 15.23 of the transmission plate. The springs 13.62 of the two ratchet opening bolts 13.6B are stronger than the springs 13.8 of the stand mechanisms. The ratchet opening bolts can slide past the ratchet 13.7 during the deployment of the support wheels. The side support apparatus may be adapted such that, after the triggering by the Bowden cable trigger 15.5, the stand mechanisms 13A, 13B deploy as quickly as possible, in particular in the range of tenths of a second.

[0120] The detent means 13.7 may have a ratchet which is arranged in a housing and which may be in the form of a small plate with a hooked form in the direction of the toothed rack. The small plate is pressed by means of a small spring against the toothing and thus forms the ratchet fastener. The housing has a bore through which a bolt protrudes during the deployment of the stand mechanism. If the stand mechanism is to be retracted, the corresponding cable pulls on the bolt and then protrudes into the bore again upwardly from below. A cone of the bolt presses against the small plate, which is set into an oblique position by the small spring, and said cone orients said small plate specifically such that the hooked form is released from the toothed rack of the stand mechanism. The ratchet is thus released again.

[0121] FIG. 13 shows, by way of example, a Bowden cable tensioner 16.9 with a diverting roller 16.91, a spring-mounted (pivot) hinge 16.92 and a spring 16.93. During the pivoting, slack can be drawn out of a cable guided over the diverting rollers 16.91. The Bowden cable tensioner is configured to compensate different working lengths of multiple cables and to hold each of the cables under tension. Such a Bowden cable tensioner is expedient in particular for the cable that actuates the plate of the traction mechanism kinematic system, in particular because said cable has a long length and can thus be held under tension.

[0122] FIGS. 14A, 14B, 14C show the functioning of individual components. FIG. 14A describes the construction of the transmission device 14 and of the Bowden cable system 16 in a generalized manner separately from the traction mechanism kinematic system. FIG. 14B illustrates the individual directions of rotation and the tension forces acting on or exerted by the individual traction mechanisms. FIG. 14C describes, by way of example, transmission ratio stages between the individual components. The transmission ratio may also be selected to be greater or smaller depending on the application.
