Backpack support system for hands-free transport of a bike on the wearer's back

Abstract

A backpack support system has a frame, which is equipped with shoulder straps and preferably also a waist belt and which preferably inherently rigid so hat the loads that occur during use, the frame only flexes by inevitable amounts in the millimeter range by which any rigid body flexes when subjected to a load. A bike mount is fastened to the frame. The bike mount is embodied so that the bike, almost exclusively by its frame or frame components such as the rear fork can be fastened directly to the frame, i.e. without luggage or a pack compartment being situated between the bike and the frame in the points at which the bike rests directly against the frame. When properly fastened, the bike is thus affixed to the frame so that it cannot move.

(18) Before explaining the disclosed embodiment of the present invention in detail, it is to be understood that the invention is not limited in its application to the details of the particular arrangement shown, since the invention is capable of other embodiments. Exemplary embodiments are illustrated in referenced figures of the drawings. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than limiting. Also, the terminology used herein is for the purpose of description and not of limitation.

DETAILED DESCRIPTION

(19) First of all, the expressions head end, foot end, vertical, horizontal, vertical axis of the wearer, and the like used here refer to the state in which the backpack is being worn properly on the wearer's back.

(20) The best overview of the backpack support system according to the disclosure for transporting a bike on the wearer's back in a hands-free way is provided by FIG. 1. In this case, hands-free means that the bike can be carried on the back without the wearer having to use a hand in order to hold the bike in its position on his back. Instead, the bike is fastened to the backpack support system so that when it is being carried, it automatically remains in its proper position on the back. This is true even if the carrying system is preferably designed so that the bike is merely hung and can be unhung by simply grasping it, without having to release a fastener or strap.

(21) The drawing clearly shows the frame 2, which in this specific instance is composed of a rod or tube frame 3 and the back plate 4. It should be stated at this point that the back plate 4 is particularly advantageous for reasons that will be explained in greater detail below. In the individual instance, however, it could also be replaced by additional sections on the rod or tube frame 3 itselffor example by horizontally and/or vertically extending struts, not shown here in the figure, between the side parts of the rod or tube frame 3, which permit an appropriate positioning and possibly adjustment of the hooks.

(22) Shoulder straps 5 are attached to the rod or tube frame 3. Ideally, the shoulder straps 5 are fastened to the rod or tube frame 3 in a vertically adjustable way in order to be able to adjust the backpack to different body sizes. This can happen because the rod or tube frame 3 is embodied like a flute, with a number of fastening holes at different heights. By means of the shoulder straps 5, the rod or tube frame 3 can be worn on the back like a backpack.

(23) As a rule, a hip belt 14 is provided. The hip belt is positioned so that it transfers the majority and ideally, at least of the load to the hip region of the wearer.

(24) The described backpack support system in the frame of this exemplary embodiment features a particularly clever way of fastening the bike so that it is ready to carry.

(25) The bike is hung on the backpack support system here by means of at leastand ideally onlyone first hook 6 and one second hook 7. The hooks are preferably designed and positioned so that the bike to be carried can be made ready for carrying by simply hanging it in the hooks. It is not necessary to additionally fasten the bike by means of cords or additional straps or hook-and-loop fasteners that participate in absorbing the weight force of the bike acting in the vertical direction.

(26) The hook 7 is intrinsically rigid and preferably is rigidly fastened as a whole to the frame 2. Basically, the same is true of the hook 6 unless this is a snap-in hook. In such a snap-in hook, at least one leg is mounted in a sprung, movable fashion to the rigidly affixed hook base in order to be able to snap the hook 7 in a form-fitting way onto the down tube of the bike framelike a similar to a clamp fastener for snapping onto the handle of a broom that is to be secured to the wall of the broom closet. Such a snap fastener is particularly advantageous because when extreme movements occur, it also prevents the bike from unintentionally coming out of the hook.

(27) Optionally, one hook or both hooks 6, 7 can also be provided with an additional closure, e.g. like a ski boot clasp or an elastomer or rubber closure (e.g. like the kind used as an additional closure for the hoods of rally vehicles) so that the frame part of the bike that is hung in the hook is additionally secured in a form-fitting way against slipping out.

(28) Regardless of the two latter options, the snap-in hook as such retains its position and orientation even under load, at least essentially. All that occurs is the elastic deformations in the millimeter or submillimeter range that are inevitable, even in rigid bodies, under load. The hooks are ideally composed of aluminum or carbon. Independently of this, they can if necessary be hollow in order to reduce weight.

(29) Both of these hooks have a particular placement. As is evident, the two hooks 6 and 7 are mounted at different heights, viewed along the vertical axis of the wearer. At the same time, the two hooks 6 and 7 are not mounted one above the other, instead being positioned spaced apart from each other in the horizontal direction.

(30) In this case, the hook 6 is the upper hook, while the hook 7 is the lower hook.

(31) The upper hook 6 is preferably mounted in the middle or essentially on the vertical center line M between the two shoulder straps 5, in the latter case with a position tolerance of +/35 mm. Ideally, its position is adjustable in the horizontal direction, i.e. the hook can be fastened in different positions in order to be able to adjust the position of the center of gravity of the bike to be carried. By contrast, the lower hook 7 is preferably mounted in an off-center position. It is then spaced apart from the vertical center line between the two shoulder straps 5 by a distance of at least 90 mm.

(32) The upper hook 6 is preferably mounted at a height that lies in the vicinity of the shoulder blades of the wearer, advantageously with a tolerance of +/50 mm. The lower hook 7 is mounted approximately at the height of the center of the back, advantageously with the same tolerance as mentioned above for the upper hook. The lower hook is preferably positioned so thatfor example in the case of a man who is 160 cm tall and a size S mountain bike with 29-inch wheelsthere is still a distance of at least 20-30 cm between the ground and the rear wheel so that the wearer is not impeded by the bike coming into contact with the ground when he is walking downhill.

(33) Ideally, the two legs that form the lower hook 7 are oriented so that they extend in a plane (or plane group) that is completely or at least essentially vertical. The hook 7 is open toward the top so that the bike is hung in it from above. The two legs that form the upper hook 6 define a plane that is oriented transversely and preferably at an angle of approximately 90 to the plane in which the two legs of the hook 6 lie. The hook 6 is open at the side oriented toward the hook 7.

(34) The legs of at least one hook or better still, both hooks, can be embodied as V-shaped or U-shaped or if need be, can also be embodied as correspondingly rectangular in the form of a double-L profile. Ideally, they are embodied as V-shaped, as illustrated by FIG. 4. Then they are able to clamp a frame part of the bike between themselves in a rattle-free way. The V-shaped legs are inclined relatively to each other, ideally so that frame tubes with an outer diameter of between 28 mm and 55 mm can be clamped in a rattle-free way between the two legs of a hook. It is particularly advantageous if the legs have a coating that increases the friction in comparison to a bare or painted metal surface, for example made of rubber, unvulcanized rubber, particularly preferably neoprene, or an elastomer, in particular a thermoplastic elastomer. This coating can be applied like a paint or can, for example, be embodied as a permanently attached or shrink-fit sleeve composed of an appropriate material.

(35) FIG. 3 gives the best view of how a bike that is to be transported is hung on the backpack support system in order to then, after the backpack support system has been slung onto the shoulders, be carried in a hands-free way. As is clear from the drawing, the bike is preferably carried in an upended fashion or in any case so that its so-called straight-ahead travel direction, which is predetermined by its wheels, assumes an acute angle ALPHA of no more than 37.5 and better still, of no more than 30 relative to the vertical. The latter is important above all because the backpack support system according to the disclosure is primarily used for carrying mountain bikes in the alpine region. Specifically in such an application, the bike cannot be carried transversely for reasons of safety and space. The two hooks 6 and 7 are arranged in corresponding fashion.

(36) The lower hook 7 is used or utilized in such a way that with a conventional diamond frame, the frame tube holding the seat post is hung in it. In full-suspension bikes, usually the rear fork is hung in the lower hook 7, in any case provided that it has a section that extends parallel to the direction of the seat post. The hook 7 is positioned and suspended so that the plumb line of the bike's center of gravity does not extend through the hook 7, but instead through the region that lies between the hook 6 and the hook 7, viewed in the horizontal direction.

(37) Because the lower hook 7 is positioned in the above-described way, it is able to absorb more than and ideally, even essentially all of the weight force of the bike acting in the vertical direction. Thanks to the off-center placement of the hook 7, the bike tends to rotate around the hook 7 so that it pivots into the hook 6. In this way, the down tube of the bike is automatically inserted into the hook 6. This also happens specifically because the hook 6 is oriented obliquely or at right angles to the hook 6, see FIG. 1. Its open hook side therefore receives the down tube that extends obliquely upward. The decisive factor is that the down tube of the bike always tends to slide into the hook 7, even if the wearer sways.

(38) This produces an extremely quick and thus secure fastening. The bike is hung in the lower hook 7 and then rotated into the upper hook 6. The removal takes place in the reverse order. In other words, both the hanging and the removal are carried out by means of a combined translatory and rotary movement. This is the most important for use in the mountains since on challenging mountain bike trails, riding sections and carrying sections often alternate so quickly that it is of essential importance to be able to load and unload the bike by simply hooking and unhooking it.

(39) The reason why the fastening is self-retaining, so to speak, is shown most clearly in FIG. 7, which schematically depicts the ratios, possibly in connection with FIG. 3. FIG. 7 clearly shows the back plate, which will be discussed in greater detail below. The upper hook 6 and lower hook 7 and the imaginary center line M between the two shoulder straps 5 are clearly visible. The upper hook 6 in this case is positioned exactly on the center line M. The lower hook 7 in this case is positioned off-center on the left side. The bike is preferably hung in the lower hook 7 so that in the transport position of the bike, a center of gravity comes to lie on the center line M. The bike consequently tends to execute movements in the clockwise direction and its down tube, as explained above, automatically rotates into the upper hook 7. If one disregards the friction forces in a first-order approximation, then the lower hook 7 absorbs the vertical weight force FG of the bike, while a force acting predominantly in the horizontal direction is exerted on the upper hook in the direction perpendicular to the surface of the down tube on which the weight acts. It is noteworthy that a force component acting in the vertical direction can be present at the upper hook 6, which inhibits an unwanted disengagement of the bike from the hook 7. Such an unwanted disengagement can potentially occur when the rear wheel of the bike briefly comes into contact with the ground when the wearer is descending a sharp slope. This unhooking safety can be significantly improved further if the upper hook is provided with a friction-increasing coating and/or the hook is provided with the V shape discussed in detail above.

(40) The following torque equilibrium occurs:
MH1:Fg*S1F2*S2=0

(41) At the same time, the following force equilibrium prevails:
Fg*S1=F2*S2

(42) As a result, the bike rests securely in the holders.

(43) The back plate 4, which has already been mentioned several times, is positioned between the bike and the padding that rests directly against the wearer's back. It forms a shield for protecting the wearer's spinal column. In the event of a backward fall such as a slip that occurs during a steep descent over loose ground, the back plate 4 prevents hard frame parts or the hooks 6 and 7 from poking into the back and distributes the load acting on the back over its entire area. For this purpose, the back plate is preferably embodied as wide enough to cover the wearer's spinal column over most of its length or over its entire length. The width of the back plate advantageously corresponds approximately to the shoulder width or to the distance between the two shoulder straps 5. The back plate 4 is composed either of sheet metal, preferably sheet aluminum, of plastic, of a wooden plate, typically a plywood plate made with waterproof glue or of carbon. As a rule, it has dimensions of at least 200 mm in the horizontal direction and at least 350 mm in the vertical direction, preferably with a thickness of between 0.3 mm and 5 mm.

(44) Preferably, the back plate 4 simultaneously functions as a base for rigidly mounting the hooks 6 and 7, ideally by means of a detent connection or screw connection that is produced without tools. The back plate and/or the hooks is/are embodied so that the hooks 6 and 7 can be mounted in different alternative positions on the back plate. In this way, the backpack support system according to the disclosure can be adjusted to the physique of the wearer and to the size and weight distribution of the bike to be transported.

(45) As is clearly shown, the back plate is equipped with different mounting openings 8 for the first hook 6. These mounting openings 8 are preferably embodied as respective oblong holes, which preferably extend in the horizontal direction. It is thus possible to mount the first hook 6 at different heights. At the same time, it is also possible to adjust its orientation relative to the center line M between the shoulder straps 5.

(46) The back plate 4 is simultaneously equipped with different mounting openings 9 for the second hook 7. These are also preferably embodied as respective oblong holes, which ideally extend in the vertical direction. It is thus possible to mount the second hook 7 at different distances from the center line M between the shoulder straps 5 and to adjust its height.

(47) At this point, reference is once again made to FIGS. 1 and 2.

(48) A rod or tube frame 3 is fastened to the back plate 4, preferably on its side directly facing the wearer's back. As is clearly shown, the rod or tube frame 3 has two rod or tube sections 10. Each of these rod/tube sections 10 has a middle section 11. The middle section 11 rests against the back plate 4 and is fastened to it, preferably screwed, riveted, or welded to it.

(49) Toward the head end, this middle section 11 is adjoined by a first edge section 12. At least in parts, the latter is curved so that it forms a fastening region for a shoulder strap 5, which lies closer to the wearer's body than the above-mentioned middle section 11. Ideally, toward the hip end, the middle section 11 is adjoined by a second edge section 13. At least in parts, the latter is curved so that it forms a fastening region for a hip belt 14, which lies closer to the wearer's body than the above-mentioned middle section 11. For this purpose, it is particularly advantageous if the second edge section 13 constitutes a hook as shown in FIG. 4, for example in the form of a hook that opens toward the top.

(50) As is clearly shown in FIG. 1, the two first edge sections 12 of the two rod or tube sections 10 are connected to each other by means of a connecting section 15.

(51) Ideally, the rod or tube frame 3 is embodied as a one-piece bent metal part in its above-described sections. Apart from the connecting section 15, it is not necessary to provide another connection of the two rod or tube sections 10 in the horizontal direction since the stabilization in the horizontal direction is provided by the back plate 4.

(52) Because the fastening points for the shoulder straps 5 and the hip belt 14 relative to the back plate 4 are shifted in the direction toward the wearer's body, the back plate and the bike that is fastened to it are spaced apart from the wearer's body. This is particularly advantageous since the rear wheel of the bike, which is carried in an upended fashion, extends into the vicinity of the wearer's fibula. It is therefore necessary to provide enough space between the wearer's fibula and the bike so that the wearer can walk largely uninhibited and can also comfortably travel longer distances.

(53) For this reason, a spacer 16 is provided at least between the hip belt and the back plate, which is most clearly shown in FIG. 2. As a rule, its thickness is chosen so that the back plate is held so that it is spaced at least 7.5 cm, or better still, at least 10 cm, and ideally, at least 14 cm from the wearer's back.

(54) This spacer 16 can be a simple pad such as a foam part.

(55) It is significantly better, however, to use the space between the hip belt and the back plate and to embody the spacer 16 as a preferably dimensionally stable hollow receptacle 17 for accommodating gear. In order to be able to neatly load the hollow receptacle, it preferably has at least one side opening for loading and unloading. In this case, dimensionally stable means that the hollow receptacle is permitted to have a certain elasticity of the kind that is inherent, for example, in a plastic box. At the forces that occur during carrying operation, it can be compressed by no more than 10 mm in the horizontal direction and in particular, cannot be crushed. In this case, a dimensionally stable hollow receptacle has the advantage that on its surface facing the wearer's back, it can be provided with a padding, which, regardless of the contents of the hollow receptacle, rests in a defined way against the wearer's back or provides additional padding to the hip belt on its side facing away from the wearer. Naturally, the spacer 16 can instead be embodied in the form of a crushable pocket, particularly if the hip belt 14 is tightly clamped between the second edge sections 13 and the pocket situated between it and the back plate 4 does not press against the wearer's back during wearing.

(56) Above the spacer 16, i.e. in the upward-elongated region between the hip belt and the back plate 4, at least one other pocket or at least one dimensionally stable hollow receptacle 17 can be provided on the side of the back plate 4 directly facing the wearer. It is attached to the rod or tube frame 3 and/or directly to the back plate. It can be useful for the pocket or the at least one dimensionally stable hollow receptacle to be provided with padding on its surface facing the wearer's back, as has already been described above for the spacer.

(57) Even if it is not explicitly depicted in the figures, it must nevertheless be stated that the back plate or the tube frame can have additional anchoring points for pockets to be optionally attached to it. The additional anchoring points are preferably embodied as openings through which, for example, the belt of a hook-and-loop fastener or a belt to be closed by means of a strap can be guided.

(58) Ideally, the backpack support system includes at least one, preferably two side pockets 20, which are ideally designed for upright accommodation of a water bottle. The side pockets 20 preferably each have a cylindrical design for positionally accurate accommodation of a water bottle in a standing position. This at least one side pocket 20 can be respectively fastened in the region of a vertically extending side edge of the back plate 4, preferably attached directly to them and/or to the respective rod or tube section 10 of the rod or tube frame 3.

(59) Preferably, the backpack support system has at least one back pocket 21. This is located under the spacer 16, between the hip belt 14 and the back plate 4. It is preferably attached directly to the second edge section 13 of the above-mentioned rod or tube sections 10. This is particularly true if they are embodied as a hook with a preferably horizontally extending section on which the back pocket can be suspended, preferably in such a way that it does not oscillate.

(60) It is particularly advantageous if the backpack support system includes at least one main compartment 22, see FIGS. 5 and 6. The main compartment 22 and the back plate 4 as well as the hooks 6, 7 are preferably embodied so that the main compartment 22 can be mounted to the side of the back plate 4 facing away from the wearer's body without tools and can be also removed from it again without tools. Preferably, the main compartment has its own shoulder straps so that the wearer can wear it in front of his chest when transporting the bike.

(61) It is particularly advantageous if the main compartment has at least one and better still, several openings into which a hook 6; 7 can be slid in order to accommodate the bike.

(62) In the optimum case, the main compartment is embodied so that it can be fastened to the back plate without tools, simply by means of or with the participation of being hung, clicked, and/or clamped in the hooks 6, 7 and can also be removed from them again without tools.

(63) It is particularly advantageous if the backpack support system includes a locking element for the front wheel, which secures the front wheel essentially in the straight-ahead riding position. The locking element can be a belt or cable with a quick-release or a click connector, is placed snugly around the down tube and transversely to the rim of the front wheel and then holds the latter captive. In this case, it is particularly advantageous if the locking element is fastened to the frame of the backpack support system in captive fashion, e.g. is tethered to it.

(64) FIG. 8 shows a second exemplary embodiment of the disclosure.

(65) Its design corresponds to that of the first exemplary embodiment, which is why everything that has been explained above for the first exemplary embodiment also applies to the second exemplary embodiment. The sole difference lies in the fact that the second exemplary embodiment dispenses with the protective back plate for weight reasons. Instead, the frame 2 has at least one additional horizontal strut 23. Ideally, the first hook 6 is mounted to this additional horizontal strut or to one of these additional horizontal struts 23. In order to be able to adjust the position of the first hook 6, the additional horizontal strut is provided with a set of holes extending along its longitudinal axis or with pairs of holes on opposite sides of the longitudinal axis from one another, by means of which the first hook 6 can be screw-mounted in different positions to the additional horizontal strut 23.

(66) In this case, at least one hole or pair of holes is also provided, whose axis or whose shared axis extends essentially perpendicular to the axis or shared axis of the other holes or pairs of holes. As a result, the first hook can be attached to the frame 2 in a folded-in position in which it lies, for example, in the plane defined by the tubes/parts of the frame 2 immediately adjacent to it. In FIG. 8, the depiction of the hook 6 that is in its folded-in position is graphically highlighted with dots.

(67) As is clearly shown, the second hook 7 is preferably fastened in basically the same way to a tube/part of the frame 2but which generally extends in the vertical directionso that its position can be adjusted in the vertical direction and likewise so that in the same way as described above for the first hook 6, it can be fastened to the frame in a folded-in position.

(68) In FIG. 8, the depiction of the hook 7 that is in its folded-in position is graphically highlighted with dots.

(69) FIGS. 9 to 16 show a third exemplary embodiment of the disclosure.

(70) This exemplary embodiment corresponds to the preceding exemplary embodiments with regard to the positioning of the hooks 6, 7 and the way of carrying the bike and with regard to various other aspects. Consequently, that which has been said above also applies to this exemplary embodiment.

(71) This exemplary embodiment differs from the preceding exemplary embodiments in that in this case, a soft backpack is used, which, during normal use of the backpack, has no frame or does not have a complete frame and therefore is particularly comfortable to wear.

(72) Typically, however, it includes apossibly also removablereinforcing plate, which serves as a shield and is made of plastic, which should prevent solid components of a bike being carried from being able to poke into the wearer's back unimpeded, even in the event of awkward movements or possible falls.

(73) This soft backpack features the fact that it includes special connectors, which will be discussed in further detail below.

(74) As soon as there is a need to carry a bike, the auxiliary frame 24 shown in FIG. 9 is fastened to the backpack by means of the special connectors.

(75) The auxiliary frame 24 features the fact that it is preferably composed of four tubes 26. Ideally, these four tubes 26 are connected to one another by means of corner connectors 25. The corner connectors are usually made of plastic. Each of the corner connectors ideally has two sleeves, which are positioned at an angle of 90 to each other. A tube 26 is inserted into each of these sleeves and fastened there. The fastening is carried out in a frictionally engaging fashion by means of a corresponding press-fit through an under-dimensioning of the sleeves relative to the tube diameter and/or by means of gluing and/or by means of a detent engagement.

(76) As is depicted most clearly in FIGS. 10 and 11, the backpack is equipped with local reinforcements. Mounting pins 27 are affixed to them, which typically have an external pin thread 28 with which, after being inserted through the envelope of the backpack and the reinforcement provided there, they are screw-mounted to the backpack. These pins have a fastening groove 29 auf an internal pin thread 30. The fastening groove 29 is not used to fasten the auxiliary frame 24 that is initially of interest here. It is used for other purposes that will be explained in greater detail below. Instead, the auxiliary frame 24 is attached as follows:

(77) As is clearly shown in FIG. 10, each corner connector 25 is placed onto a respective pin 27 so that a complementary cavity of the corner connector 25 accommodates the pin 27. Then a knurled screw 31 is inserted through the corner connector from the side of the corner connector facing away from the backpack and is then screwed into the internal pin thread 30. In this way, the corner connector is firmly connected to the pin 27 of the backpack. As soon as all of the connections of this kind have been produced, one to each corner connector 27, then the backpack is attached to the auxiliary frame 24 that is placed against it from the outside.

(78) As indicated above, the pins 27 have a multiple functionality. This is because the internal pin thread 30 is only needed if an additional element is to be fastened to the pin in a particularly stable fashion, for example the auxiliary frame 24. If only lighter things are to be fastened to the pin, for example an additional bottle holder, outside pockets, a sleeping bag holder, and the like, then this is carried out in that an appropriate form-fitting element that is not shown in detail here is slid over the pin 27, which then engages by means of its latch in the groove 29 of the pin. This achieves a thread-free quick connection for outside pockets and the like.

(79) The auxiliary frame is in turn equipped with a first hook 6 and a second hook 7, as has already been described above for the system according to the disclosure so that the statements relating to that apply here as well.

(80) The special hooks 6, 7 used here, which incidentally can also be used in this form for the other exemplary embodiments, excel by means of their particularly clever mechanism, which permits a particularly simple folding-in and, when needed, folding-out of the respective hook 6, 7.

(81) The hooks are ideally injection molded of plastic and in the best case, in such a way that they each have an essentially closed hook top and hook bottom, which are connected to each other by means of ribs Ri that extend in an alternating oblique fashion, as is shown the most clearly in FIG. 12. As is shown in with particular clarity in FIG. 14, the ribs extend across most of the hook in the longitudinal direction or extend across at least 40% of the length of the hook, not extending across the entire hook, instead ending at two middle walls Mw that extend with their broad sides perpendicular to the broad sides of the ribs. The middle walls Mw preferably form guide pockets 35 between themselves, whose purpose will be discussed in greater detail below. In the region of the tips of the hooks, the ribs can extend through the entire hook so that the ribs can define a plurality of regions, which are openings DB that each pass transversely through the entire hook so that the latter is particularly light-weight.

(82) In places where even higher-quality embodiments are required, these hooks can also be cast out of metal, for example out of a zinc pressure die-casting compound, or can even be forged out of aluminum or milled from a solid block.

(83) As is shown most clearly in the sectional view associated with FIG. 12, the hooks have a tubular section 32, which encompasses the entire circumference of the tube. The play of the tubular section 32 is chosen so that the tubular section 32 can be slid transversely on the auxiliary frame 24 and can also be rotated, each of these in the unlocked state.

(84) In this way, the entire hook 7 shown in FIG. 12 can be moved from its ready position shown in FIG. 12 in the direction indicated by the rotation arrow PD into a rest position that is pivoted by 90 counterclockwise.

(85) Naturally, the hook must not pivot or slip while the bike is being carried. An unwanted pivoting is preferably prevented by means of a movable detent plate 33 that is built into the hook and a groove 34 in each of the tubes of the auxiliary frame 24 or at least in each of the tubes that is provided for a hook. In the locked state, the detent plate 33 engages in the groove 34 of the tube of an auxiliary frame, as shown in FIG. 13 and FIG. 14. As a result, the hook 6 cannot be rotated relative to the tube.

(86) At this point, it is necessary to discuss the above-mentioned guide pocket 35, which is formed between the middle walls Mw. This is because the detent plate 33 is accommodated in the guide pocket 35 of a hook 6, 7. As is shown most clearly in FIG. 13, two guide screws or guide pins 36 extend through each guide pocket. By means of their oblong holes or guide slots 37, the detent plate 33 is held in the guide pocket so that it is able to move in translatory fashion, preferably so that the main part of the guide plate 33 is positioned inside the guide pocket 35. Usually, the guide plate 33 protrudes from the guide pocket 35 in only two places. Namely at the place in which it constitutes the actuation surface 37, which is ideally embodied in the form of a pistol-like trigger (see FIG. 12) and, with the section that is designed for engagement in the groove 34 of the respective tube 26. It is also clearly shown in FIG. 13 that the guide plate is pushed in the direction of the tube 26 by a spring 38, which is preferably accommodated by an opening in the guide frame and exerts a spreading action between the guide plate and the hook. This means that the detent plate 33 engages in detent fashion in the groove 34 as soon as the hook has been pivoted into its use position in which the detent plate 33 comes to lie exactly over the groove 34.

(87) The tube is preferably prevented from sliding by means of the clamping ring 39. The clamping ring 39 is embodied so that it is immovably fixed to the respective tube 26 of the auxiliary frame 24 as soon as its clamping screw is tightened all the way. In this way, the clamping ring prevents the hook 6, 7, which comes to rest against it in a form-fitting way, from executing a translatory movement. For the sake of good form, it should be noted that a hook 6 or 7 is not limited to being associated with just one clamping ring 39. Instead, it is also possible for a clamping ring 39 to be positioned at both ends of the hook in order to prevent the hook from executing a translatory movement in both directions. An alternatively conceivable design is one in which in the completely tightened state, a clamping ring 39 forces the tube 26 passing through it into such an oval state that this prevents the hook from slipping. This has the advantage that then only a single clamping ring has to be provided per hook. This saves material and also reduces the amount of effort that is required in order to immobilize a hook.

(88) For the sake of completeness, it should also be noted that one suitable option is to provide the surface of the hook that comes into contact with the bike as intended with a covering made of a particularly soft or particularly high-friction plastic. One suitable option for this, for example, is a TPE, or ideally a soft plastic, which has been applied to the hook blank by means of overmolding and firmly bonded to it.
