Description

TECHNICAL FIELD

The present invention relates to a fixing system for attaching a handlebar grip attachment to a handlebar.

STATE OF THE ART

Handlebar grips are used to control the steering of two- or multi-wheeled vehicles, especially bicycles and motorcycles. A handlebar requires a handlebar grip that transmits the steering force and the driver's control inputs between the driver and the handlebar. During the ride, the steering can be exposed to high forces and vibrations. Furthermore, control elements that are essential for the vehicle can be located on the handlebar grip. The handlebar grip is therefore highly relevant for controlling the vehicle and for driver safety. In particular, the fixed position of the handlebar grip in the axial and radial direction to the handlebar must be permanently guaranteed. At the same time, handlebar grips should be able to be maintained, replaced and functionally changed, so a reversible attachment to the handlebar is essential.

A reversible fastening option for handlebar grips is used, for example, in the US 6 615 687 B2 disclosed. Here, an insert and an end piece are used for both ends of the handlebar grip for securing. In addition, in one version, the outer end of the handlebar grip is closed with a screwed-on end plate. The patent step reveals a large number of necessary fastening elements and leaves the exact type of force transmission for fastening open. For example, fits and screw connections are listed, but also irreversible adhesive or welded connections for force transmission.

In the FR 2 849 824 B1 a handlebar grip attachment is disclosed that is achieved by an axial screw connection on the outer end of the handlebar grip. A conventional screw is used to screw through an end part into a part secured radially in the handlebar. The inner end of the handlebar grip is closed with a screw ring. This type of attachment requires an external thread on the inner end of the handlebar grip and four fastening elements. The screw connection can only be loosened with the appropriate tool.

From the CN 2 848 690 Y and the US 10 787 220 B2 Clamp connections are known that press the handlebar grip onto the handlebar rod in a force-locking manner. Clamp rings are used for this, which are placed on both ends of the handlebar grip tube. The handlebar grip tube has grooves so that it can be deformed and pressed onto the handlebar rod. Both patents describe simple screws that can be inserted in a radial direction in order to achieve the pressing using the clamp ring. This means that two components are required per handle end, which must be opened and closed using a screwing tool.

In the DE 20 2013 101 848 U1 a clamp connection is revealed. The handlebar grip tube has grooves on the outer end so that it can be pressed onto the handlebar using a clamp ring. The force is applied by turning a clamp. This can be opened and closed by hand, but the ideal clamping force must be set by first adjusting the clamp width using a threaded pin and a nut screwed onto the threaded pin. The handle must be locked at the inner end using a screw ring. It is known that such clamps with a lever tend to become "loose" and the clamping force decreases over time, so that the clamp width must be readjusted or the clamp replaced. In addition, the nut required for adjustment can easily be lost.

From the DE 425 252 A is a handle attachment for handlebars of bicycles and motorcycles. A handle sleeve is pressed onto the handle tube by a conical clamping chuck coupled to the handle edge and a union nut provided with a counter-cone. The clamping chuck is coupled to the handle sleeve by a two-part coupling ring, which on the one hand is provided with a thread for the union nut and on the other hand engages the open end of the handle sleeve by means of a recess. However, three elements (coupling ring, union nut and clamping chuck) are required to attach the handle sleeve. In addition, the handle sleeve is only connected to the coupling ring via a short section, namely a ring, which is why the handle sleeve can rotate around the handlebar axis.

From the US 7 814 812 B1 A non-rotating handle assembly for a handlebar is known. The handle assembly comprises a tubular handle body, a pair of split compression rings and a pair of end caps. The compression rings and the end caps are attached to the beginning and end of the handle body, which itself has two threads. When the end caps are screwed onto the handle body, the split compression rings reduce their diameter and press against the handlebar to prevent the handle body from rotating. However, four elements are necessary for attaching the handle body, which are easily can be lost. In addition, the handle body itself must be provided with at least two threads so that the end caps can be screwed on. Accordingly, the handle body must be made at least in sections from a material that supports a threaded connection. A softer material such as hard rubber would not allow such a threaded connection.

Handlebar grip attachments that have a clamping jaw section are also known from the prior art. To attach the handlebar grip attachment to a handlebar, the handlebar grip attachment is pushed over the handlebar. A clamp is then placed over the clamping jaw section and fixed either using a screw connection or a lever, whereby either a tool or a threaded rod with a nut must be used.

TASK

It is therefore the object of the present invention to provide a device which enables a handlebar grip attachment to be attached to a handlebar in a simple manual manner without the need for a tool to attach or remove the handlebar grip attachment. At the same time, the invention should comprise the smallest possible number of components required for attaching the handlebar grip attachment.

SOLUTION

The object is achieved with a handlebar grip attachment ring fixing system with the features of claim 1. Further advantageous embodiments can be found in the subclaims, the description and the embodiments.

GENERAL BENEFITS

The invention enables a handlebar grip attachment to be easily attached to a handlebar. The attachment is made possible by a simple, manually produced, reversible screw connection, which means that no tools are required to attach the handlebar grip attachment. The number of components required to attach the handlebar grip attachment is very small, as only a clamping ring and a clamping ring attachment ring are required to attach the handlebar grip attachment to the handlebar.

DESCRIPTION OF THE INVENTION

The invention relates to a handlebar grip attachment ring fixing system (1.0) (herein also: device) for fixing a handlebar grip attachment (2.0) to a handlebar rod (3.0), wherein fixing is understood to mean a reversible fastening or connection of the handlebar grip attachment to the handlebar rod.

The handlebar (3.0) is understood to be the element that is essentially aligned orthogonally to the steering axis of the handlebar and is gripped by a driver with the hands in order to steer the vehicle, e.g. a two-wheeler / bicycle, by rotating the handlebar around the steering axis. The steering axis usually intersects with the handlebar in the middle of the handlebar.

A handlebar grip attachment is a commercially available handlebar grip attachment that is essentially designed as a hollow cylinder that is pushed over the handlebar and comprises an outer handlebar grip attachment end (2.1) and an inner handlebar grip attachment end (2.2) opposite the outer handlebar grip attachment end. When used as intended, the handlebar grip attachment is arranged on the handlebar so that the inner handlebar grip attachment end points towards the steering axis of the handlebar.

It is known from the state of the art that handlebar grip attachments of this type are fixed to the handlebar, for example, via a clamp, whereby a clamp can be designed as in the DE202013101848U1 The clamp is guided onto a clamping jaw section (2.5) and a lever is moved to compress the clamping jaw section and thus connect the handlebar grip attachment to the handlebar in a force-fitting manner. To enable the clamping jaw section to be compressed, the clamping jaw section includes a clamping jaw recess (2.6) which serves to allow the material of the clamping jaw recess to move around the circumference of the handlebar when the clamping jaw section is compressed.

Instead of a clamp, which has the disadvantages listed above, this invention provides a clamping ring (4.0) for fixing the handlebar grip attachment to a handlebar. This comprises a clamping ring external thread (4.1), which is intended so that a clamping ring attachment ring described below can be screwed onto the clamping ring. In addition, the clamping ring comprises at least two clamping jaw recess insert thickenings (4.2). These are designed in such a way that they fit, preferably exactly, into the clamping jaw recess, whereby the clamping ring can be arranged essentially radially in a form-fitting manner within the clamping jaw recess. The clamping ring cannot therefore be rotated around the clamping jaw section without considerable effort. The clamping jaw insert thickenings The advantage of these clamps is that the material of the handlebar grip attachment (more precisely: the material of the clamping jaw section) is pressed more firmly against the handlebar, thus increasing the clamping effect used to attach the handlebar grip attachment.

A radial mold shot is understood here to mean that the clamping ring is arranged/positioned on the handlebar grip attachment in such a way that the clamping ring cannot be rotated about the longitudinal axis of the handlebar grip attachment, but can be displaced along the longitudinal axis in the direction of the steering axis of the handlebar, whereby this displacement is defined herein as an axial displacement.

According to the invention, the handlebar grip attachment is fixed to the handlebar by screwing the clamping ring attachment ring (5.0) described below onto the clamping ring. The result of the screwing is that the diameter of the clamping jaw section (2.8) is reduced, whereby the handlebar grip attachment is fixed to the handlebar in a force-fitting manner. The diameter of the clamping jaw section is reduced because the clamping ring diameter (4.4) of the clamping ring is reduced.

The handlebar grip attachment can also be designed in such a way that it has two opposing clamping jaw sections and clamping jaw recesses, which advantageously increases the clamping effect (when using two handlebar grip attachment ring fixing systems).

Since the device/system according to the invention essentially consists of two components - the clamping ring and the clamping ring attachment ring - it is advantageously achieved that the number of necessary components is as small as possible.

The clamping ring has a clamping ring width (4.5) that preferably corresponds to the clamping jaw section length (2.9), thereby enabling a maximum contact area between the clamping ring and the clamping jaw section. The advantage of a maximum contact area is that the clamping jaw section can be compressed more effectively to fix the handlebar grip attachment.

The length of the clamping jaw section is usually determined by the design of the handlebar grip attachment. This usually includes a bead (2.4) which is arranged between the outer end of the handlebar grip attachment and the inner end of the handlebar grip attachment and is arranged closer to the inner end of the handlebar grip attachment. The bead separates the hand rest surface (2.3) of the handlebar grip attachment from the clamping jaw section.

The clamping jaw section length can be variable, whereby a larger clamping jaw section length advantageously results in a larger compressible contact surface between the clamping ring and the clamping jaw section length and thus an increased frictional connection for fixing the handlebar grip attachment.

The thread of the clamping ring external thread has an external thread width (4.7). The external thread begins on one of the sides of the clamping ring. The dimension of the external thread width preferably corresponds to half the dimension of the clamping ring width. Furthermore, the dimension of the external thread width can be a maximum of 2/3 smaller than the dimension of the clamping ring width. Furthermore, the dimension of the external thread width is at least two full thread pitches, with a thread pitch being defined as the width of a full revolution of the thread profile. A larger dimension of the external thread width is advantageously accompanied by a firmer grip of the clamping ring attachment ring on the clamping ring external thread.

For proper use, the clamping ring is positioned on the clamping jaw section so that the side of the clamping ring's external thread, which begins on one side of the clamping ring, is oriented towards the outer handlebar grip attachment end.

The clamping jaw recess insert thickening has a clamping jaw recess insert thickening ring height (4.3). This is preferably more than twice as large as the clamping ring ring height (4.6). However, the clamping jaw recess insert thickening ring height can only be as large as the clamping jaw recess insert thickening contacts the handlebar. However, this is not desired because the material of the clamping jaw section should be guided past the clamping jaw recess insert thickening during compression.

The clamping jaw recess insert thickening comprises a clamping jaw section guide bevel (4.8). This is designed to allow the material of the clamping jaw section to be guided past while the diameter of the clamping jaw section is reduced. The angle of the clamping jaw section guide bevel is preferably selected such that the clamping jaw section guide bevel is oriented parallel to a clamping jaw section bevel (2.7). This ensures that the material of the clamping jaw section is guided along the clamping jaw section guide. The exact design of the clamping jaw section guide bevel, in particular its angle in relation to the radius of the clamping ring, can be determined by a specialist.

In a particularly preferred embodiment, the clamping ring comprises a continuous clamping ring recess (4.9), the length of the continuous clamping ring recess corresponding to the clamping ring width. The continuous clamping ring recess enables the material of the clamping ring to be compressed while the clamping ring attachment ring is being screwed on. This can advantageously ensure that the material of the handlebar grip attachment, in particular the clamping jaw section, can be pressed against the handlebar.

The clamping jaw recess insert thickenings are spaced apart from each other and separated from each other by the continuous clamping ring recess, which has a width of the continuous clamping ring recess (4.10).

The width of the continuous clamping ring recess can be determined by a person skilled in the art. Preferably, however, the width is chosen so that the clamping ring can be compressed far enough to achieve the best possible fixation of the handlebar grip attachment to the handlebar. If the invention is intended for the fixation of a handlebar grip attachment to a handlebar of a bicycle, the width of the continuous clamping ring recess is preferably between 2 and 8 mm, more preferably between 3 and 6 mm and particularly preferably 5 mm.

In a preferred embodiment, the clamping ring comprises at least one, preferably two and more preferably three non-continuous clamping ring recesses (4.11), wherein a non-continuous clamping ring recess comprises a clamping ring recess width (4.12). The presence of a clamping ring recess advantageously enables material savings on the one hand and a more flexible bending behavior of the clamping ring on the other hand when the clamping ring is compressed - caused by the clamping ring attachment ring. Furthermore, a clamping ring recess enables easier drainage of any water that may be present between the inner surface of the clamping ring clamping jaw and the clamping jaw section, which advantageously increases the grip of the clamping ring on the clamping jaw section.

In a further embodiment, the clamping ring does not include any non-continuous clamping ring recesses. This makes the manufacture of the clamping ring easier and more cost-effective.

The clamping ring comprises at least one clamping ring clamping jaw (4.13) if there are no non-continuous clamping ring recesses and preferably more than one clamping ring clamping jaw if there is at least one non-continuous clamping ring recess. Each clamping ring clamping jaw comprises a clamping ring clamping jaw inner surface (4.14), whereby these are spaced apart from one another by the clamping ring diameter. The clamping ring clamping jaw is compressed by unscrewing the clamping ring attachment ring, so that the clamping ring diameter is reduced by the clamping ring clamping jaw inner surfaces moving towards one another. The clamping ring clamping jaws are connected via a web (4.16). The clamping ring external thread is guided over a web.

The at least one clamping ring clamping jaw has the function of establishing a force-locking connection between the clamping ring and the clamping jaw section and, on the other hand, establishing a force-locking connection between the clamping jaw section and the handlebar. Due to its surface-like design, the inner surface of the clamping ring clamping jaw advantageously enables the strongest possible force-locking connection between the aforementioned elements.

In one embodiment, the inner surface of the clamping ring clamping jaw is grooved, ridged, or provided with another surface structure in order to advantageously increase the grip between the clamping ring and the clamping jaw section.

A clamping ring clamping jaw inner surface can comprise a friction-increasing means. This can be groove-shaped or groove-like elevations or depressions in the surface of the clamping ring clamping jaw inner surface. This is advantageously accompanied by an increased grip of the clamping ring in the clamping jaw section. Another advantage is that any water that may be present between the clamping ring clamping jaw inner surface and the clamping jaw section can escape more easily and the grip of the clamping ring on the clamping jaw section is increased.

The clamping ring attachment ring has an internal thread (5.1) and can be connected to the clamping ring in an axially positive manner by screwing it on and removed from the clamping ring by unscrewing it. It should be emphasized that the clamping ring attachment ring can be screwed on and unscrewed manually, without the need for a tool.

The internal thread of the clamping ring attachment ring is designed in such a way that it can be turned onto the clamping ring external thread in order to to achieve an axial positive connection between the clamping ring and the clamping ring attachment ring. The selected positive connection advantageously enables a very simple construction of the system/device according to the invention.

An axial positive connection is understood here to mean a connection that, when used as intended, does not allow any axial displacement of the clamping ring and the screwed-on clamping ring attachment ring. It is clear to the expert that an axial positive connection only exists when the clamping ring attachment ring is screwed sufficiently onto the clamping ring so that the intended fixation of the handlebar grip attachment is achieved.

The internal thread of the clamping ring attachment ring has an internal thread width (5.2). The internal thread width preferably corresponds to the dimension of the external thread width or is a maximum of 2/3 smaller than the external thread width. A larger internal thread width advantageously enables a better grip of the clamping ring outer ring on the clamping ring.

In a preferred embodiment, the clamping ring attachment ring comprises a circumferential clamping ring clamping jaw contact zone (5.3), the function of which is to contact the clamping ring clamping jaw outer surface (4.15) and to exert a force on it. The clamping ring clamping jaw outer surface is arranged on the side of the clamping ring on which the clamping ring external thread is also arranged. Preferably, the clamping ring attachment ring can only be screwed onto the clamping ring so far that the circumferential clamping ring clamping jaw contact zone only presses on the clamping ring clamping jaw outer surface and not on the clamping ring external thread.

When used as intended, the clamping ring is positioned on the clamping jaw section in such a way that the side with the clamping ring external thread is oriented towards the outer handlebar grip attachment end and the side with the clamping ring clamping jaw outer surface(s) is oriented towards the steering axis.

In a preferred embodiment, the circumferential clamping ring clamping jaw contact zone and the clamping ring clamping jaw outer surface are designed to taper slightly in the direction from the inner end of the handlebar grip attachment to the steering axis of the handlebar. This means that the clamping ring clamping jaw contact zone and/or the clamping ring clamping jaw outer surface are arranged at an angle in relation to the longitudinal axis of the handlebar grip attachment. This advantageously enables better force transmission when the clamping ring attachment ring is screwed onto the clamping ring in order to achieve more effective compression of the clamping ring clamping jaws.

Screwing the clamping ring attachment ring with its internal thread onto the external thread of the clamping ring results in a positive connection, whereby the inner surfaces of the clamping ring clamping jaws are pressed together while the clamping ring attachment ring is being screwed onto the clamping ring, so that the distance between the inner surfaces of the clamping ring clamping jaws is reduced.

In order to further stabilize the positive connection, at least one groove can be embedded in the circumferential clamping ring contact zone, in which a friction-increasing element, for example a ring made of a plastic (e.g. thermoplastic, elastomer) or a rubber ring is embedded. As the clamping ring attachment ring is screwed onto the clamping ring, the friction between the circumferential clamping ring clamping jaw contact zone and the clamping ring clamping jaw outer surface is increased. This advantageously allows an improved positive connection to be achieved, which is advantageous, for example, during a journey with a lot of vibration.

Likewise, the outside of the clamping ring attachment ring can include a friction-increasing element so that a user can better grip the clamping ring attachment ring during manual screwing. This allows the user to screw the clamping ring attachment ring onto the clamping ring more firmly and without slipping.

In a preferred embodiment, the clamping ring and/or the clamping ring attachment ring is made entirely or in part from a metal (e.g. aluminum, steel) or a plastic (preferably a thermoplastic). The metal can be anodized or galvanized and is preferably resistant to weather influences such as cold or rain. The use of a plastic advantageously enables weight and cost savings. In order to make a clamping ring external thread made from a plastic and/or an internal thread of the clamping ring attachment ring made from a plastic more mechanically resistant, a thread made from a plastic can be vapor-coated or galvanized with a metal.

In a further embodiment, the clamping ring attachment ring comprises at least one or more circumferential grip improvement elements. Such an element can be designed, for example, as a rubber ring which is mounted within a circumferential groove in the surface (5.4) of the clamping ring attachment ring. arranged and is firmly connected to the groove. This advantageously allows a user to grip the clamping ring attachment ring better in order to tighten it.

In a further embodiment, the clamping ring and/or the clamping ring attachment ring comprises a magnetic means. This can be, for example, a permanent magnet (e.g. neodymium magnet) that is embedded in the clamping ring and/or the clamping ring attachment ring. The magnetic means advantageously prevents the clamping ring and/or the clamping ring attachment ring from accidentally slipping off the handlebar, for example when changing a handlebar grip attachment. It is clear to those skilled in the art that this requires the handlebar to comprise a metal to which a magnet adheres. Alternatively, the handlebar can also comprise the magnetic means.

In one embodiment, the device according to the invention comprises a self-adhesive metal tape film that a user can arrange around a handlebar. This advantageously means that the magnetic means can also be used on a bicycle with a handlebar made of aluminum.

Finally, it should be noted that all features mentioned in the application documents and in particular in the dependent claims, despite the formal reference to one or more specific claims, should be granted independent protection, even individually or in any combination.

Further advantages, features and possible applications of the present invention will become apparent from the following description of embodiments and the drawings. All described and/or illustrated features, either individually or in any combination, form the subject matter of the present invention, regardless of their summary in the claims or their references.

In addition, it should be noted that the person skilled in the art will undoubtedly recognize that the individual features described in the above specific embodiments can be combined with one another in an appropriate manner, provided that there is no contradiction, whereby a separate description of various possible combinations is omitted in order to avoid unnecessary repetition.

The 3A shows a handlebar (3.0) with a clamping jaw section (2.5) pushed onto it and a clamping ring (4.0) pushed onto it. Since the clamping jaw section insert thickenings (4.2) are arranged within the clamping jaw recess (2.5), the clamping ring (4.0) is arranged essentially radially in a form-fitting manner within the clamping jaw recess (2.5), so that the clamping ring (4.0) cannot be rotated around the handlebar axis (3.0) without considerable effort. For the intended use, it is not intended that the clamping ring (4.0) can be rotated around the clamping jaw section (2.5) or the handlebar axis (3.0).

Screwing on the clamping ring attachment ring (5.0) (indicated by the curved arrow) results in the clamping ring clamping jaws (4.13) being pressed in the direction of the handlebar axis (3.0), whereby the material of the handlebar grip attachment (2.0), in particular the material of the clamping jaw section (2.5), is pressed against the handlebar (3.0), whereby the handlebar grip attachment (2.0) is fixed to the handlebar (3.0). During this process, the width of the continuous clamping ring recess (4.10) is reduced.
