Bicycle

The present invention relates to a bicycle.

Bicycles are known from the prior art (see Figure 6), comprising a framework-like frame with essentially at least one top tube 2, a seat tube 4, a bottom bracket 6, a down tube 8, a head tube 10, a front wheel fork 12, upper rear wheel struts 14 and lower rear wheel struts 16 and a luggage rack 18. As can be seen in Figure 6, the luggage rack 18 is rigidly connected to the bicycle frame at two fastening positions, where one fastening position is in the immediate vicinity of the connection between the upper rear wheel struts 14 and the seat tube 4 (in some embodiments also directly on the seat tube) and the other fastening position is on a gusset plate 17 connecting the upper 14 and lower rear wheel struts 16, on which the rear wheel of the bicycle is also mounted. Such luggage carriers are known, for example, from DE-3110870 C2, DE-3343844 C2, DE-3817396, DE-4020563 C2, GM-7617628, GM-7912107 or G-8108128.6.

Due to the aim of keeping the total weight of the bike as low as possible, the luggage carrier system is usually made of very thin struts, which, however, is not always the case due to the long struts resulting from the above-mentioned luggage carrier construction and, in particular, when the load is higher, due to uneven roads or

the like, or if the luggage rack is incorrectly mounted, this can lead to strong vibrations in the luggage rack system and unpleasant rattling noises. Furthermore, on bicycles that have this conventional luggage rack design, the rear lower fastening point of the luggage rack is in the immediate area or directly on the rear wheel suspension and the drive components located there. To dismantle the rear wheel and/or the drive components located there, the luggage rack fastening often has to be loosened and removed. Likewise, removing the luggage rack often requires dismantling the rear wheel and/or the drive components located there and/or parts of the wheel suspension. This results in a not insignificant amount of work.

Furthermore, so-called suspension bicycles are known, which in their basic structure essentially correspond to the previously mentioned type of bicycle, but in contrast to this type, have a spring-mounted rear wheel and are therefore particularly suitable for use in rough terrain. For this purpose, for example, a rear wheel suspension is provided, in which the lower rear wheel struts are designed as swing arms with their front ends articulated to the bottom bracket and their rear ends articulated or rigidly connected to the upper rear wheel struts. The upper rear wheel struts, in turn, are movably coupled to a lever-spring damping system attached to the seat tube and/or top tube. If this rear wheel construction is deflected due to an uneven road surface or the like, the swinging movement of the lower rear wheel struts is transferred to the lever-spring damping system via the upper rear wheel struts and is cushioned and dampened by this. Due to the movable arrangement of such a rear wheel construction, the conventional luggage carrier systems described above are unsuitable for suspension bikes. Suspension bikes are therefore,

and of course primarily with regard to rough riding conditions, more spartanly equipped. Nevertheless, even riders of a suspension bike often want the comfort of a conventional bike, although the latter usually does not meet sporting requirements.

The invention is based on the object of creating a simple and effective bicycle that avoids the aforementioned disadvantages of the prior art and that, even in an embodiment as a suspension bicycle, at least optionally offers the comfort of a conventional bicycle.

This object is achieved by a bicycle according to the invention having the features of claim 1.

Accordingly, the bicycle according to the invention, which can be designed in particular as a suspension bicycle, comprises a framework-like frame with essentially at least one top tube, a seat tube, a bottom bracket, a down tube, a head tube, a front wheel fork, upper rear wheel struts, lower rear wheel struts and a luggage rack, whereby the luggage rack is fixed exclusively to the upper rear wheel struts. A fixation to the rear wheel struts also means a fastening in which one or more components of the luggage rack engage a part extending, for example, in the transverse direction of the vehicle between the left and right upper rear wheel struts. Preferably, the luggage rack is fastened in a substantially central region of the upper rear wheel struts in relation to the longitudinal extent of the same. The luggage rack can be designed as an integral part of the bicycle frame, i.e. permanently connected to it, or it can be detachably fixed to the bicycle frame using suitable fastening means. In the sense of the invention, a single "tube" of the bicycle frame can certainly comprise one or more individual tubes or struts as well as additional struts. Furthermore, for a ladies' bicycle, for example, the

Upper tube should run essentially parallel to the lower tube or coincide with it.

The bicycle according to the invention offers a luggage carrier system in which the luggage carrier can be integrated into the frame construction in a simple and effective modular manner. Since the luggage carrier is only fixed to the upper rear wheel struts, the luggage support is already in a raised position on the bicycle frame, so that the luggage carrier as a whole can be made very compact and thus stable and very lightweight. In contrast to bicycles with conventional luggage carriers, the luggage carrier of the bicycle according to the invention can also be manufactured in a comparatively simple manner, which leads to less manufacturing effort and reduced production costs. As a result of the modular integration of the luggage carrier into the frame construction, the luggage carrier can even be manufactured and assembled during frame production, depending on the type of bicycle selected, which in turn simplifies and shortens the production process. The previously mentioned compact design of the luggage carrier also prevents disturbing vibrations that are detrimental to the strength of the bicycle and thus contributes to a solid bicycle construction. Due to the arrangement of the luggage carrier according to the invention, which, as already mentioned above, can be fixed in a substantially central area of the upper rear wheel struts, the fastening or connection points between the luggage carrier and the bicycle frame are located in an area far away from the rear wheel suspension and the drive components arranged there, so that assembly work on the luggage carrier can be carried out independently of possible work on the rear wheel suspension and/or drive parts and vice versa. The separation of the rear luggage carrier fastening points from the rear wheel suspension area also leads to a more clearly structured, more manageable bicycle concept. Furthermore, the luggage carrier is

due to its specific arrangement and design, it is also easily accessible and can be assembled or disassembled easily and in a relatively short time, which increases the handling and ease of maintenance of the bicycle according to the invention. Depending on the design of the luggage carrier, a conventional bicycle can also be converted into a bicycle according to the invention, even by the end user. Finally, the fixing of the luggage carrier according to the invention, i.e. the attachment of the luggage carrier exclusively to the upper rear wheel struts, now also allows the use of luggage carriers on suspension bikes, since the rear wheel suspension of a suspension bike can perform a free pivoting movement for the purpose of suspension/shock absorption, without the luggage carrier hindering this movement or complex luggage carrier structures being required. The solution according to the invention therefore also offers riders of a suspension bike the comfort of a conventional bike if required, while the sporty character of the suspension bike is fully retained.

A further advantageous design feature of the invention provides that the luggage carrier of the bicycle comprises a frame-like construction with a frame part forming a luggage support and running essentially parallel to the longitudinal axis of the bicycle, as well as support legs that extend from the luggage support to the upper rear wheel struts and are attached to them detachably or permanently. This represents a particularly favorable solution in terms of construction, which is primarily suitable when using tubes as the starting material for luggage carrier production. The invention is not, however, limited to this variant. In principle, other basic luggage carrier constructions can also be used within the meaning of the invention, for example those in which the support legs are formed by a single, the functions of the

The component taking over the support struts has been replaced and the like.

Preferably, the support legs of the luggage carrier are adjustable in length, which ensures that the luggage carrier can be easily adapted to different bicycle types and sizes.

It has also proven to be advantageous that the ends of the support legs pointing towards the upper rear wheel struts each have a fastening device on the front. In this way, the luggage carrier can be easily attached to the upper rear wheel struts. In this context, it has also proven to be positive that the upper rear wheel struts have a fastening device that corresponds to the front fastening device of the support legs of the luggage carrier. This not only ensures that the luggage carrier is firmly attached to the bicycle frame, but the fastening means can also be adapted to the type of frame used.

A further advantageous design feature of the invention provides that the front fastening device of the support legs comprises a hole with an internal thread. In this context, it has also proven to be advantageous that the fastening device of the upper rear wheel struts comprises a through-opening that runs essentially perpendicular to the longitudinal extension of a respective upper rear wheel strut and passes through it, through which a screw corresponding to the front internal thread of a support leg can be inserted. In this way, the luggage carrier is not only particularly simple and can be fixed to the upper rear wheel struts with simple and inexpensive fastening means, but the forces and/or moments acting from the luggage carrier on the upper rear wheel struts are also advantageously introduced into the bicycle frame.

Preferably, the said through-opening in a respective upper rear wheel strut is formed by a sleeve inserted into a respective upper rear wheel strut, with the front ends of the sleeve each forming a support surface for the screw head and the front end of a support leg of the luggage carrier. The sleeve therefore not only allows the luggage carrier to fit snugly against an upper rear wheel strut, but also advantageously absorbs the compressive forces that would otherwise act on the said rear wheel strut when the screw inserted through the sleeve is screwed onto the internal thread of a support leg and deform it. Furthermore, the sleeve also absorbs the forces and moments resulting from a load on the luggage carrier and directs these into the bicycle frame in a structurally advantageous manner.

According to a preferred embodiment of the invention, the sleeve is soldered into the upper rear wheel strut, with a brazing process being particularly advantageous. In general, however, the sleeve can also be welded, glued or attached to the upper rear wheel strut in another suitable manner.

Another advantageous embodiment of the invention provides that the fastening device of the upper rear wheel struts comprises support shoes or the like, each of which can be firmly connected to a respective support strut of the luggage carrier, which simplifies the positioning and fixing of the luggage carrier to the bicycle frame. The support legs of the luggage carrier can then be designed, for example, as simple tubes, the free ends of which are each inserted into a support shoe fixed to the upper rear wheel struts and secured in a suitable manner against slipping out of the support shoe. The support shoe itself can be secured with suitable fastening means such as a claw, a clamp, a pipe clamp-like section, a

clamping device or the like in order to be fixed to an upper rear wheel strut.

According to a further advantageous embodiment of the invention, it is provided that the fastening device comprises a positioning device. This positioning device facilitates the attachment and alignment of the luggage carrier in a suitable position on the upper rear wheel struts.

Advantageously, the support legs of the luggage carrier run essentially at right angles to the upper rear wheel struts when the bike is viewed from the side. This not only allows the luggage carrier to be easily attached to the bike frame using the screw connection described above or using support shoes, but also enables the forces and moments resulting from loading the luggage carrier to be transferred effectively to the bike frame.

If the acute angle between the support legs and the luggage support of the luggage carrier is in a range of approximately 25° to 55°, the luggage carrier, in its arrangement according to the invention, assumes a position on the upper rear wheel struts in which the luggage support is advantageously in a substantially horizontal position with respect to the bicycle in the riding position and the support legs of the luggage carrier run essentially at right angles to the upper rear wheel struts when the bicycle is viewed from the side. The luggage carrier shape can thus be adapted to the inclination of the upper rear wheel struts and an ergonomically favorable luggage carrier arrangement can be achieved. In this context, it has also proven to be advantageous that the support legs of the luggage carrier run essentially parallel when the bicycle is viewed from the side. Depending on the geometry of the bicycle frame and in particular the upper

Of course, the support legs of the rear wheel struts can also run at a certain angle to each other.

A further advantageous variant of the invention provides that the support legs of the luggage carrier are articulated to the luggage support and/or the angle between the support legs and the luggage support is adjustable. Such an adjustment can, for example, be such that the articulated, adjustable support legs can be locked in a certain position, so that the luggage carrier can be fully loaded after locking, without the position of the support legs in relation to the luggage support changing. If the support shoes described above are used for the luggage carrier to attach it to the upper rear wheel struts, such a lock can even be omitted, since the support shoes stabilize the support legs to such an extent that the entire luggage carrier is rigid and fully load-bearing. In addition, articulation points can also be provided on the lower support leg ends of the luggage carrier, i.e. those facing the upper rear wheel struts, and/or on the upper rear wheel struts themselves, in order to provide an additional degree of freedom when adjusting the luggage carrier. The articulated attachment of the support legs to the luggage support or the ability to adjust the angle between the support legs and the luggage support allows the luggage carrier to be optimally adapted to different frame geometries and in particular to the respective shape of the upper rear wheel struts.

Preferably, the luggage carrier comprises a rail or sliding rail system for detachably attaching additional luggage carrier parts, such as saddlebags, baskets, child seats and the like. In this way, the luggage carrier can be easily adapted to the individual needs of the cyclist.

With regard to the stability of the bicycle frame, it has proven to be particularly positive that the top tube of the bicycle according to the invention is curved upwards in an arc shape according to a further preferred design feature.

Advantageously, the upper rear wheel struts of the bicycle according to the invention are attached to the top tube immediately in front of the seat tube. This results in a particularly favorable introduction of the force occurring at the rear wheel struts into the bicycle frame.

Finally, according to a further advantageous design feature of the invention, the upper rear wheel struts are curved upwards in an arc shape, which in turn has a positive effect on the stability of the bicycle frame. In combination with the aforementioned curved top tube, the curvature of the upper rear wheel struts and the curvature of the top tube are preferably coordinated with one another in such a way that when the bicycle is viewed from the side, the upper rear wheel struts and the top tube form a continuously curved curve. This design can be implemented particularly advantageously with the previously explained attachment of the upper rear wheel struts to the top tube. In this way, a very stable, light and torsion-resistant bicycle frame can be realized.

Preferred embodiments as well as further details and advantages of the bicycle according to the invention are now described and explained below with reference to the drawings. It shows:

Fig. 6 is a schematic side view of a bicycle according to the prior art.

In the following description and in the figures, to avoid repetition, identical components are also identified with the same reference numerals unless further differentiation is required.

Fig. 1 shows a schematic side view of a first embodiment of the bicycle according to the invention. The bicycle comprises a framework-like frame with a top tube 2, a seat tube 4, a bottom bracket 6, a down tube 8, a head tube 10, a front wheel fork 12, upper rear wheel struts 14, lower rear wheel struts 16 and a luggage carrier 18. As can be clearly seen in Fig. 1, the luggage carrier 18 is fixed exclusively to the upper rear wheel struts 14, the luggage carrier 18 in the present embodiment being in a substantially central position relative to the longitudinal extension of the upper rear wheel struts 14.

area of the same. In the bicycle frame shown in Fig. 1, the top tube 2 is also curved upwards in an arc shape and, together with the rear wheel struts 14, which are also curved upwards in an arc shape, forms a continuously curved curve when the bicycle is viewed from the side. Furthermore, the upper rear wheel struts 14 are attached to the side of the top tube 2 immediately in front of the seat tube 4.

In Fig. 2, which shows a schematic enlarged side view of the bicycle frame of the bicycle according to the invention in the area of the upper rear wheel struts 14 with a luggage carrier attachment according to a first embodiment, further details of the bicycle according to the invention can be seen. The luggage carrier 18 of the bicycle comprises a frame-like construction, essentially composed of tubular components, with a frame part forming a luggage support 18.2 and running essentially parallel to the longitudinal axis of the bicycle, as well as four support legs 18.4, of which only two can be seen in the side view. The support legs 18.4 extend from the luggage support 18.2 to the upper rear wheel struts 14. The support legs 18.4 can be designed to be adjustable in length in order to ensure that the luggage carrier can be easily adapted to different bicycle types and sizes. Since the luggage carrier 18 and the two upper rear wheel struts 14 are arranged essentially symmetrically to the plane of symmetry spanning the bicycle frame and the attachment of the luggage carrier 18 to the upper rear wheel struts is carried out analogously, only one of the two adjacent rear wheel struts will be referred to for further explanation. As shown in Fig. 2, the ends of the front and rear support legs 18.4 pointing towards the upper rear wheel struts 14 each have a fastening device in the form of a front-side bore with an internal thread 20. The upper rear wheel struts 14 of the bicycle are also provided with a fastening device

which corresponds to the aforementioned fastening device of the support legs 18.4 of the luggage carrier. The fastening device of the upper rear wheel strut 14 comprises two through-openings 22 arranged at a distance from one another and running essentially perpendicular to the longitudinal extension of the upper rear wheel strut 14 and passing through it. Each through-opening 22 is assigned to a front end of a support leg 18.4. The luggage carrier 18 is detachably fastened to the upper rear wheel strut 14 by means of a screw 24 which is inserted through the through-opening 22 and screwed to the internal thread 20 of a support leg 18.4.

Each through-opening 22 is formed by the central opening of a sleeve 26 inserted into the upper rear wheel strut and brazed to it, which sleeve simultaneously covers and reinforces the through-opening 22. The soldering points are indicated in the drawing by the reference number 28. The front ends of the sleeve 26 serve as support surfaces 26.2 for the screw head 24.2 or for the front end of a support leg 18.4 and are finely machined if necessary.

As indicated in Fig. 2, in the present case the acute angle α between the support legs 18.4 and the luggage support 18.2 of the luggage carrier 18 is approximately 38°. This angle α can of course deviate considerably from the stated value depending on the type of bicycle and the inclination of the upper rear wheel strut 14. In today's frame designs, however, the angle α will usually be in a range of approximately 25 to 55°. When looking at the bicycle according to the invention in the side view shown in Fig. 2, the front and rear support legs 18.4 of the luggage carrier 18 extend essentially

parallel to each other and a respective support leg 18.4 extends essentially at right angles to a tangent applied to the upper rear wheel strut 14 at the connection point between the support leg and the upper rear wheel strut.

Furthermore, the luggage carrier 18 comprises a rail or sliding rail system for detachably fastening additional luggage carrier parts, such as saddlebags, baskets, child seats and the like. This rail system is not shown in the figures for the sake of clarity.

The fastening device of the upper rear wheel strut 14 or the fastening device of the support legs 18.4 of the luggage carrier can comprise a positioning device that facilitates the attachment and positioning of the luggage carrier 18 on the bicycle frame. Such a positioning device is shown in the detailed enlargement X in Fig. 2. In the present case, this positioning device is designed as a cylindrical shoulder 30 provided on the end of the support leg 18.4 associated with the upper rear wheel strut 14, which has a smaller diameter than the outer diameter of the support leg 18.4 and which can be inserted into a corresponding cylindrical recess 26.4 in the sleeve 26 of the upper rear wheel strut 14. However, the invention is not limited to this embodiment. In general, any positioning device suitable for the intended purpose can be used.

Fig. 3 shows a schematic view of the bicycle frame of the bicycle according to the invention according to Fig. 1 and 2 in several viewing directions. In Fig. 3, the positions of the through holes 22 or sleeves 26 in the two upper rear wheel struts 14 can be seen particularly well in the partial top view of the bicycle frame. In the present case, a total of four through holes 22 or sleeves are required to attach the luggage carrier 18.

2 6 are provided. The number of through holes 22 or sleeves can, however, be increased or decreased if necessary. According to the sectional view A-B in Fig., the sleeves 26 facing the rear wheel suspension of the frame are inclined by 5° relative to the plane of symmetry spanning the bicycle frame. The sleeves 26 facing the seat tube 4 can have the same inclination, but this does not necessarily have to be the same as the first-mentioned sleeves 26. Furthermore, it is generally possible to attach the sleeves 26 in the upper rear wheel struts 14 without such an inclination.

Fig. 4 shows a schematic side view of a second embodiment of the bicycle according to the invention. This variant is essentially the same as that according to Fig. 1, but in contrast to this the bicycle is designed as a suspension bicycle, with straight upper rear wheel struts 14 and a straight top tube 2.

Fig. 5 shows a schematic enlarged side view of a bicycle frame of the bicycle according to the invention in the area of the upper rear wheel struts with a luggage carrier attachment according to a second embodiment. As can be seen from Fig. 5, the support legs 18.4 of the luggage carrier 18 are attached in an articulated manner 32 to the frame part of the luggage carrier 18 that forms the luggage support 18.2, and the ends of the support legs 18.4 pointing towards the upper rear wheel strut 14 are held in claw- or clamp-like support shoes 34 attached to the upper rear wheel strut 14 and are secured in a suitable manner against slipping out of the support shoes 34. The support shoes 34 also absorb the bending loads resulting from a load on the luggage carrier 18, so that the joint connection 32 between a respective support leg 18.4 and the frame part of the luggage carrier 18 forming the luggage support 18.2 is used to achieve

a stable structure does not need to be rigidly fixed.

The invention is not limited to the above embodiments, which are merely general examples. Within the scope of protection, the bicycle according to the invention can also take on other embodiments than those explained above. For example, it is not absolutely necessary for the support legs of the luggage carrier to run in a straight line, but they can also contain bends or be curved. Furthermore, other suitable components, e.g. one or more plate-shaped elements or the like, can also be used instead of the tubular support legs of the luggage carrier. In order to attach the luggage carrier, hinge points can also be provided on the upper rear wheel struts in order to create an additional degree of freedom when adjusting the luggage carrier. It is also conceivable to design the hinge points in such a way that they can be rigidly fixed in a desired angular position. The luggage carrier can also be attached to the upper rear wheel struts in another suitable way, even in a non-detachable manner, e.g. by welding or the like. Finally, the bicycle frame geometry is also variable.
