Description

Description motorcycle handlebar

The present invention relates to a handlebar for a bicycle with two handlebars, which are connected via a respective boom with a common carrier rod.

Handlebars for two-wheelers are known in many designs and are used in particular for bicycles or motor-driven two-wheelers (motorcycles). As a rule, such links are designed as a pipe construction and in particular made of a single, suitably bent pipe section. In the design, ie in particular in the specification of the bending shape for such handlebars, in particular provided for the respective vehicle steering geometry plays an essential role, in combination with the geometric and other properties of the chassis a particularly high maneuverability and maneuverability of the two-wheeled at Motorcycles but in particular a high stability and driving safety is sought. However, with regard to the shape, such links are usually also adapted to the expected body measurements of the driver, so that they are designed to be substantially suitable for a particularly wide variety of different drivers on the basis of average body measurements.

As a further fundamental design criterion for such handlebars, the design plays a major role, which should provide a harmonious, appealing overall picture in particular by resorting to design elements of the actual two-wheeler.

With regard to the physical properties of the vehicle and the desired adaptation to a variety of driving styles, such handlebars can also be designed to be adjustable. From US 2003/0084746 A1, for example, an adjustable handlebar for motorcycles is known in the two pins having intermediate pieces be used with their pins in an intended handlebar maintenance, with a suitable handlebar mount for attachment of the actual handlebar is provided at the intermediate pieces. Due to the increased number of independently positionable individual elements additional degrees of freedom for the actual assembly are provided, which allow an individualized adaptation to individual drivers or at least favor. However, to be used in the respective handlebar mount spacers of this handlebar complicate a highly precise, in particular on both sides of the handlebars one hundred percent same attachment. This has the consequence that either the handlebars are crooked or that one of the fasteners does not grip properly.

Moreover, such a handlebar is visually only partially conditionally compatible with designerischen concepts just in view of the predetermined by the desired adjustability increased number of components to be joined, as a rather technocratic overall impression due to the design of the connecting elements is difficult to avoid.

The invention is based on the object to provide a handlebar of the type mentioned above, which allows for an aesthetically pleasing overall impression in a particularly simple manner an individualized adaptation to the needs of the driver.

This object is achieved by the handle bars are each inserted with one of its ends in a recess provided on the arm recess, wherein the support rod at its two ends in each case in a further, provided on the respective arm recess is inserted, said mated connections in their orientation are selectable and detachable, and wherein in each case a screw connection is provided for the production of the connection between the boom and support rod or handle whose associated connecting screw engages in an end arranged in the support rod or handle bar internal thread and in the assembled state substantially parallel to the longitudinal end axis of the Support rod or the handlebar is aligned. The handlebar thus essentially comprises the following five basic components: the carrier bar, which can be attached in the manner of the central suspension or holding point in a conventional manner via the handlebar clamp on the fork bridge or other usual mounting location for the handlebar of the bicycle, two arms of which in each case an end with one end of the support rod is connectable and geometrically allows a "Höherlegung" of the receiving points for the other components, and two handle bars, each of which end with one of the boom at its "free" end is connectable and in turn carries at its free end the respective handle for the driver.

Advantageous embodiments of the invention are the subject of the dependent claims.

The invention is based on the consideration that the handlebar should in principle be configurable with regard to an individualized adaptation to the driver and for this purpose should be composed of a suitably selected plurality of individual components. In this case, however, to not let the effort in the assembly of the handlebar too high, on the other hand, not too many components should be provided with the appropriate adjustment needs. As has been found, the now provided components are particularly suitable for this purpose, wherein the configuration and adaptation to the individual driver is made possible in particular by the selectable orientation in the connection of the components by mating. By said design of the screw for the assembly of the components is also achieved that the forces necessary to maintain the respective connection coaxially, ie parallel to the respective end-side longitudinal axis, are introduced into the respective component. These holding forces are thus aligned orthogonal to the direction of force of the rotational locking mechanism formed by the toothing, resulting in a complete power-side decoupling of the connection on the one hand and the detent in the rotational positioning. In this way, the corresponding force components or the corresponding tightening momen- te be selected independently of each other with regard to a particularly high mechanical stability of the overall system.

In order for a secure connection of the handlebar consisting of five parts is ensured and the connections can be made synchronously to each other and, above all, easily, the booms on their recesses advantageously corrugations to form the teeth on. In a corresponding advantageous embodiment, the respective ends of the handlebars or the carrier rod adapted as multi-teeth designed so that a positive engagement is possible. For a particularly easy executable connection of the individual parts with each other is also provided in a further advantageous embodiment of the corrugations having recesses at least one paragraph.

A particularly high flexibility in the positioning of the components with high mechanical stability is achieved by expediently the corrugation on the respective recesses of the boom about 20 notches and corresponding to the associated multi-tooth has about 20 teeth, corresponding to a pitch of 18 °. As has been found to be quite surprising, just by such a division on the one hand a comparatively high flexibility in the orientation, namely with a pitch of 18 °, achievable, on the other hand a high mechanical stability and thus resilience of the connection is guaranteed. The compromise between flexibility in terms of positioning options on the one hand and mechanical load capacity on the other hand is therefore particularly well met.

The handle bars have in an advantageous embodiment at one of its ends also a corrugation with about 20 notches and at least one paragraph. The provided on the recesses of the boom corrugations and the trained on the handle bars corrugation correspond by the same number of notches with each other, so that just in the production of items, the number of tools required can be kept low or no constant replacement of the tools to the Production machines must be made. In order to facilitate the handling particularly, corrugations with approximately 20 notches and at least one shoulder are also provided at both ends of the support bar. The corrugation formed on the support rod and the at least one shoulder advantageously correspond with the notches provided on the recesses of the arm and the formed shoulder such that an adjustment and positioning to the individual driver can also be effected reliably and quickly here by simply plugging these individual parts together ,

The advantageous embodiment by mating the items allows a driver to set the configuration and adjustment of the handlebar individually and time-saving. In this case, the adjustment and positioning for the driver is simplified by the formation of the corrugation and the notches.

In an advantageous embodiment, the support rod and the handle bars are screwed via screw with the arms. This ensures that the individual parts are fixed in the configured and adjusted position. The set for the individual driver positioning of the items can not unintentionally twist or adjust.

In order to make the booms look aesthetic and not like the usual classic handlebars, the booms are preferably designed with a polygonal cross section. The cantilevers, which are formed from a metal usually used for handlebars, preferably aluminum, may be made of solid material, the side surfaces may be provided in particular with labels or ornaments. In an alternative and preferred embodiment, however, the arms are broken in places. On the one hand, this has the advantage that the arms look more appealing in design, on the other hand, the weight of the arms is also reduced by the recesses.

In a particularly advantageous embodiment, considered to be inventive in its own right, the arms are designed in several parts, with each arm particularly preferably comprising one main body and two associated side covers. In the main body (or of course alternatively in the or the side cover) while receiving channels for cables or trains can be incorporated, so that with particularly simple means an internal cable routing is possible. In particular, a particularly simple internal laying of cables or trains is possible with this design, since these can be easily inserted in the disassembled state of the side cover in the respective receiving channel and then the side cover can be mounted. Thus, the handlebar is also particularly suitable for retrofitting with aesthetically pleasing appearance.

The advantages achieved by the invention are in particular that allow the plug-in running handlebars, boom and support rod, which are in mated connection in their orientation selectable and solvable, in a particularly simple and fast way an individual configuration and adaptation to a driver.

An embodiment of the invention will be explained in more detail with reference to a drawing. Show:

3 is an exploded view of a recess on one of the arms and one of the handle bars,

Fig. 4 shows an alternative embodiment of a motorcycle handlebar, and

Fig. 5 to 9 the motorcycle handlebar gem. Fig. 4 in different views.

Identical parts are provided with the same reference numerals in all figures. The handlebar 1 according to FIG. 1 for a bicycle is composed of several individual parts which form the basic components. It comprises a support rod 2, which serves as a central suspension or stopping point and can be mounted in a conventionally known manner via a handlebar clamp, not shown here, on a triple clamp or other usual mounting location of the bicycle. The link 1 comprises, as further basic components, two outriggers 4, one of which is connected in the region of its respective end 6 with one end 8 each of the carrier bar 2. For this purpose, 4 recesses 10 are provided on the arms, in which the support rod 2 is introduced.

The boom 4 geometrically allow a "Höherlegung" of the receiving points for the two handle bars 12, each of which is connected at one end to each of the boom 4 at its free end.The arms 4 have at these ends 6 recesses 10, in The two handle bars 12, which are also basic components of the handlebar 1, carry at their free ends the respective handle (not shown here) for an individual driver The five basic components of the handlebar 1 are preferably made of aluminum. but can also be made of other or different metals.

In order to fix the components, so on the one hand, the support rod 2 and on the other hand, the handle bars 12, suitable for mating with their respective ends in the respective recess 10, an associated screw 16 is provided in each case. The screw 16 is provided in particular for preventing unwanted displacement, rotation or loosening of the respective items. As in particular the exploded view acc. FIG. In the exemplary embodiment, each of the screw connections 16 respectively comprises a connecting screw 18 which, with its external thread, is arranged in an associated internal thread 20 arranged directly in the respective component to be fastened, ie directly in the support bar 2 or directly in the respective handle bar 12 intervenes. The handlebar 1 is designed specifically for an individual adaptability to the ergonomics of the driver while maintaining high stability and mechanical robustness. In order to allow a freely selectable orientation of the base components relative to one another and thus an individualized adaptation to the respective driver in a particularly simple and mechanically reliable manner, the arms 4 have a corrugation 22 within their end-side recesses 10 at their inner circumference. Corresponding to this, the grip rods 12 and the support rod 2 are provided with their respective ends provided for insertion into one of the recesses 10 with an outer corrugation 24 adapted to the respective corrugation 22. The corrugation 22 and the associated outer corrugations 24 are adapted to each other in the sense that they form in each recess 10 inserted handle bar 12 and support rod 2 each have a toothing together and thus a rotary locking mechanism, so that a rotation of the respective component around its longitudinal axis in the inserted state is not possible.

For a particularly high mechanical stability on the one hand with particularly high flexibility for adaptation to the respective driver on the other hand, the

Screw connection 16 and the teeth formed by the corrugations 22, 24 decoupled and executed independently. In order to make this possible, the screw 16 is each designed so that, as indicated by the arrow 26 in the mounted state, the connecting screw 18 with its longitudinal axis largely, in the illustrated embodiment, parallel to the longitudinal axis 28 of the respective component, ie the support rod 2 and the handle bar 12, is aligned. In other words, the end of the respective handle bar 12 and arranged on the support rod 2, provided for receiving the connecting screw 18 internal thread 20 is arranged with its central longitudinal axis parallel to the longitudinal axis 28 of the respective component, ie coaxially.

The respective component, that is to say the carrier bar 2 and / or the handle bar 12, can be straight or alternatively also bent or cranked. In such cases, the "longitudinal axis 28" herein denotes the "end-face" ge longitudinal axis ", ie that longitudinal axis, which is assigned to the end-side portion of the respective component.

As a result of the stated design, it is achieved that the forces necessary for maintaining the respective connection are introduced coaxially, ie parallel to the respective longitudinal axis 28, into the respective component 2, 12. These holding forces are thus aligned orthogonal to the direction of force of the rotational locking mechanism formed by the toothing, resulting in a complete power-side decoupling of the connection on the one hand and the detent in the rotational positioning. Thus, the corresponding force components or the torque corresponding thereto in view of a particularly high mechanical stability of the overall system can be selected independently suitable.

In a variant, the longitudinal axis of the connecting screw 18 may also be slightly inclined relative to the longitudinal axis 28 of the respective component, but in any case the component of the orientation parallel to the longitudinal axis 28 should be the predominant.

The toothing-forming combination of corrugation 22 and associated outer corrugation 24 is preferably formed by a number of indentations or teeth arranged on the outer or inner circumference of the respective component. The number of teeth determines the pitch of the teeth and thus the fineness with which the rotational position of the components can be selected and adjusted to each other. In principle, any number of teeth is possible, but in view of a high degree of flexibility in the positioning of the components while at the same time being kept simple, a number of about 20 teeth is preferred.

Particularly preferably, the toothing for one or more of said toothing points can also be embodied as so-called Hirth toothing, in which the surface of the toothing is tapered. The booms 4 are designed with a polygonal, rectangular in the embodiment, cross-section. This achieves particularly good torsional and torsional rigidity, which has a favorable effect on the mechanical stability of the overall system.

In the lateral direction of the boom 4 are executed broken. As a result, on the one hand the weight of the boom 4 and thus of the entire arm 1 is reduced. But also the aesthetic design is highlighted. In the embodiment according to FIGS. 1, 2 are each four apertures 30 formed in an oval shape. Both the number of apertures 30 and their shape can also be chosen differently.

In the partially enlarged view in FIG. 3, the recess 10 with the provided on its inner circumference ribbing 22 clearly visible. Adapted to this, the handle bar 12 carries the associated outer corrugation 24 in the vicinity of its free end. Furthermore, in the embodiment shown here, which is considered to be particularly preferred, a shoulder 32 is formed within the recess 10. Inwardly to the shoulder 32 connects to a receiving channel 34 with a round cross-section. Corresponding to this, the handle bar 12 in the end region of the corrugation 24 is also provided with a shoulder 36, which is adjoined in the direction of the free end by a spigot 38 with a likewise round cross-section adapted to the free cross-section of the receiving channel 34 from its dimension , By this particularly preferred embodiment of the connection between the handle bar 12 and the boom 4, which of course can equally be used for the connection between the support rod 2 and boom 4, a particularly reliable axial guidance of the components relative to each other and thus a particularly high mechanical Stability achievable, wherein also by the paragraphs 32, 36 also an end stop for the insert is formed, which allows a particularly precise positioning.

Im in the FIG. 1 to 3 illustrated embodiment, the boom 4 in solid construction, ie as a solid material, and to save weight and off Opened for reasons of aesthetic design. In an alternative variant, as shown in FIGS. 4 to 9 is shown, the handlebar 1 ^' but also be provided with multi-part arms 4 ^' . This variant is considered to be inventive in terms of both the design of the boom 4 ^' as well as in terms of combination with the components and constructions already explained above.

The handlebar 1 ^' according to FIGS. 4 to 9 is also executed multi-component and includes as essential components, the support rod 2, the boom 4 ^' and the two handle bars 12. Analogous to the construction of the previously described handlebar 1 are also the handlebar 1 ^', the support rod 2 and the handle bars 12 each end connected via screw 16 with the arms 4 ^' . With regard to construction and individual components according to the screw 16 that of the handlebar. 1

In contrast to the handlebar 1, the handlebar 1 ^', however, designed for internally routed cable, so that a separate external attachment, for example, brake, coupling or signal lines from the handle bars 12, starting from the actual two-wheeler is no longer required. In order to enable this internal cable guide in a particularly simple manner, the boom 4 ^' in this variant are made in several parts.

In this case, each of the arms 4 ^'in each case comprises a base body 40 and two laterally mounted side covers 42. In FIG. 4, the handlebar 1 ^' with two of the respective arm 4 ^' disassembled side covers 42 is shown. As already shown in FIG. 4 can be removed, 40 receiving channels 44 are incorporated into the body, in which any necessary cables, trains or the like can be performed starting from the handlebars and laid. Apart from these channels, the base body 40 also has a substantially rectangular cross-section, so that analogously to the arms 4, a correspondingly high torsional or torsional rigidity can be achieved even for the arms 4 ^' . Also in this embodiment, the screw 16 are each aligned with a substantially parallel to the end-side longitudinal axis 28, with its external thread in the respectively associated, directly incorporated into the respective component internal thread 20 connecting screw 18 is executed. The teeth formed by the corrugation 22 in combination with the outer corrugation 24 is also provided here. In addition, while still a cover 46 is provided, with which the head of the connecting screw 18 is covered, and which may be decorated with aesthetic or design elements.

In FIG. 6, the main body 40 is shown in detail. Clearly visible are the receiving channels 44 arranged on both sides as well as the receptacle 10 arranged in the region of the end 6 with the corrugation 22 arranged on the inside, the shoulder 32 and the receiving channel 34 adjoining the latter inwardly.

In FIGS. 7.8, the handlebar 1 ^'is shown partially in a partially assembled state in each case in a different perspective, the side covers 42 not yet being partially mounted. In contrast, FIG. 9 the handlebar 1 ^' fully assembled.
