The invention relates to a device for indirect attachment of an accessory to a bicycle handle bar. The coupling device comprises a handle bar coupling member and an accessory coupling member. The handle bar coupling member comprises fastener elements for rigid fastening of the coupling device to the bicycle handle bar and the accessory coupling member has at least two different accessory fastening positions.
Devices for fastening of accessories such as bags, map holders, lights, bells, and other equipment to a bicycle handle bar have been previously described. As the available space for attaching accessories on a bicycle handle bar is limited, the handle bar tends to become crowded with holders and attachment devices.
DE 10 2010 011 266 A1 discloses a device for attaching two accessories to a bicycle handle bar. The device in DE 10 2010 011 266 A1 has two different accessory attachment arrangements carried by a single fastener device which is attached to the bicycle handle bar. The attachment arrangements may, for instance, be a first attachment arrangement for a bicycle handle bag at the front of the device and a second attachment arrangement for a bicycle light arranged above and slightly behind the first arrangement. The second arrangement may have a cylindrical part with a diameter corresponding to the handle bar diameter and may be provided with additional fastener elements which are inserted at the ends of the cylindrical part.
Although the device in DE 10 2010 011 266 A1 allows for more than one accessory being attached along the same stretch of a handle bar, thus economizing with the limited room on the handle bar, it has a complicated structure and requires excessive manipulation in order to fit all parts together in a correct relative position and to attach the different accessories in the correct places. Furthermore, the device in DE 10 2010 011 266 A1 offers only limited adjustability of the relative positions of the accessories once they have been attached to the device.
A further accessory holder device is disclosed in EP 477 010 A1. The accessory holder in EP 477 010 A1 comprises an inner part which is attached to a bicycle handle bar and an outer holder part which can be attached to the inner part in different positions by means of mating toothed arrangements allowing the angle of the holder part to be set to different positions in relation to the inner part. Although permitting initial selection of a suitable attachment angle for the holder part, the holder device in EP 477 010 A1 does not allow for adjustment of the position of an accessory after the device has been mounted on a handle bar. Another drawback with the device in EP 477 010 A1 is that it only allows for one accessory to be attached thereto.
DE 20 2008 011 299 U1 discloses a comparatively complicated fastener arrangement which allows an accessory to be tilted and locked in different positions.
Accordingly, there remains a need for a simplified bicycle handle bar coupling device allowing multiple accessories to be attached along the same stretch of a bicycle handle bar and offering easy adjustment of the position of the accessories.
In accordance with the invention there is offered a coupling device for indirect attachment of an accessory to a bicycle handle bar, the coupling device comprising a handle bar coupling member and an accessory coupling member, the handle bar coupling member comprising fastener elements for rigid fastening of the coupling device to the bicycle handle bar and the accessory coupling member having at least two different accessory fastening positions. The different accessory fastening positions are provided on a curved element which is part of the accessory coupling member and forms a curved accessory fastening trajectory which extends radially around the bicycle handle bar when said coupling device is attached to said bicycle handle bar.
The accessory coupling member has a transverse axis which transverse axis is arranged to coincide with a bicycle handle bar axis when the coupling device is mounted on the bicycle handle bar. When the accessory coupling device is correctly mounted on the bicycle handle bar, the curved trajectory which is defined by the shape of the curved element of the accessory coupling member extends in the radial direction around the transverse axis of the accessory coupling member and around the bicycle handle bar. In order to provide high versatility with regard to the number and location of the accessory fastening positions, the curved trajectory may occupy at least 90° of a full revolution around the transverse axis of the accessory coupling member. It is to be understood that although the curved trajectory may have a uniform curvature, non-uniformly curved trajectories extending around the bicycle handle bar are also contemplated within the scope of the invention.
The accessory coupling member of the invention is a unitary element having multiple fastening positions i.e. two or more fastening positions. The fastening positions are spaced apart along the curved trajectory allowing a user to select a suitable position for attaching one or more bicycle accessories as defined herein and are optionally arranged to allow a bicycle accessory to be moved between different fastening positions without decoupling the bicycle accessory from the accessory coupling member. The accessory coupling member is indirectly attached to the handle bar by means of the handle bar coupling member and is fixed in position relative to the handle bar. Shifting between the different accessory fastening positions on the accessory coupling member takes place by moving an accessory or an intermediate accessory fastener element between the fastening positions and not by moving the accessory coupling member. Accordingly, in the coupling device of the invention, the accessory coupling member is rigidly attached to the handle bar and its position in relation to the handle bar remains the same when shifting between different fastening positions.
The accessory coupling member may comprise a curved guiding rail wherein the trajectory on which the attachment positions are arranged is defined by the shape of the curved guiding rail.
As disclosed herein, the trajectory may have a uniform radius of curvature or a non-uniform radius of curvature. The radius of curvature is generally considerably larger than the radius of curvature of the handle bar around which the trajectory extends. The curved trajectory is preferably spaced away from the handle bar and may extend around the handle bar at a radial distance in the order of 2 times or more of the radius of the handle bar. The spacing between the handle bar and the curved trajectory may vary along the trajectory.
The curved trajectory may be defined by the shape of a curved guiding rail, wherein the guiding rail may have a uniform radius of curvature or may have a non-uniform radius of curvature. The curvature and length of the trajectory may be selected such that the coupling device is particularly suitable for use with specific bicycle handle accessories. For instance, when mounted on a bicycle handle bar, the coupling device may have an attachment trajectory having a relatively larger radius of curvature on a part facing upwards and/or to the rear of the bicycle in order to present a relatively flat attachment portion towards a rider of the bicycle and a relatively smaller radius of curvature on a part facing to the front of the bicycle, i.e. away from a rider of the bicycle. An arrangement of this kind may be suitable when wishing to attach a device which should be viewable and/or accessible for manipulation by a user when riding the bicycle. Such rider-interactive devices include electronic equipment having a display, map holders, bicycle lights, etc. which are commonly attached on top of the handle bar, or towards the rider-facing side, i.e. the rear of the handle bar. The front part of the attachment trajectory, may be shaped to present a greater curvature in order to allow for vertical or generally vertical attachment of a hanging accessory at the front of the bicycle. Such hanging accessories include conventional bicycle bags and baskets, as well as specialized trunks, pods and bags, e.g. lap-top bags.
The accessory coupling member may comprise two or more curved guiding rails, such as two to four curved guiding rails. Furthermore, the accessory coupling member may comprise an accessory fastener element for fastening of an accessory to the accessory coupling member.
The guiding rails may be provided with teeth or cogs arranged to interact with an accessory fastener element for step-wise adjustability of the accessory fastener element along the guiding rail or guiding rails. An accessory fastener element is an intermediate fastener element serving to couple the accessory to the guiding rails by means of a mating fastener element on the accessory. Alternatively, a fastener element on the accessory may be configured for direct attachment to the one or more guiding rails.
Two identically curved guiding rails may be arranged parallel to each other with a gap for receiving a fastener element between the rails. The edges of the rails facing towards each other may be provided with teeth or cogs allowing step-wise movement of the fastener element along the track defined between the guiding rails.
Non-step-wise adjustment of a fastener element along a guiding rail or between two guiding rails may be achieved by a fastener element that is frictionally engaged with the guiding rail or guiding rails. In order to increase/decrease friction between the guiding rail or guiding rails and the fastener element, the fastener element may be clamped onto a guiding rail or between two guiding rails such that the connection between the fastener element and the guiding rail or guiding rails is tensioned by the fastener element being pressed against the guiding rail or guiding rails. If desired, means for adjusting the amount of tensioning may be provided, so that the tensioning may be relieved e.g. by manually opening a clamp or pressing together a pair of fastener legs on a fastener elements in order to be able to easily move the fastener element to a new position along the guiding rail or guiding rails.
The one or more guiding rails and any fastener elements may be made from any suitable material such as plastic or metal. Suitable metals include light-weight metals such as titanium and aluminium.
The accessory coupling member may comprise more than one accessory fastener element, such as up to three accessory fastener elements allowing attachment of up to three different accessories.
When more than one accessory fastener element is provided on the accessory coupling device, the accessory fastener elements may include one or more fastener element located at a fixed accessory fastening position. However, at least one accessory fastener element may be movable along the trajectory between different accessory fastening positions.
Locking members may be arranged at the different accessory fastening positions for releasably locking a fastener element in the different accessory fastening positions. The locking members may be in the form of teeth or cogs or may be locking pins, locking buttons, clamps or any other suitable locking device allowing releasable locking of the fastener element in a selected attachment position.
Multiple accessory fastening positions may be arranged along the trajectory with the accessory fastener element being slidably movable along the trajectory between the multiple accessory fastening positions.
The multiple accessory fastening positions may be arranged at predetermined locations along the trajectory. The predetermined accessory fastening positions may be provided by any suitable position-determining means such as notches, teeth, or hooks arranged along the trajectory allowing step-wise movement between the fastening positions. The fastening positions may be equidistantly arranged along the trajectory or may be arranged with varying spacing between the fastening positions. The position-determining means can be designed to also serve as locking means ascertaining that the accessory fastener element remains in a selected position. Accordingly, the position-determining means may be configured to interact with the accessory fastening element to create a connection that can only be broken by applying a greater force than would normally arise during use of the accessory coupling devise. The strength of the connection between the position-determining means and the accessory fastener element is determined by the physical design of the interacting elements such as the depth of grooves or notches and the height of teeth or other protrusions. As an example, when the accessory is a bicycle bag or similar that may be designed to carry objects of a total weight of several kilograms, the force required to break the connection and move the fastener element should be high enough to counteract gravity. However, it is important that the connection force is sufficiently low to allow the connection to be manually broken, so that the position of an accessory may be easily adjusted. For some accessories, such as electronic displays, map holders, lights, etc. it may even be an advantage if the position of the accessory can be easily adjusted while riding the bicycle. Accordingly, the connecting device may be designed to only hold lighter equipment securely in a selected position while heavier accessories such as bags may be placed at an end position on the trajectory where they may be hindered from moving out of position under the influence of gravity by a stop element such as a stop bar or stop knob.
The multiple fastening positions for an accessory fastener element on the coupling device or a fastener element on a bicycle accessory may alternatively be arranged continuously along the trajectory so that the fastener element is slidably movable along said trajectory in a non-stepwise manner allowing a user full freedom to select a suitable attachment position along the trajectory. In order to ascertain that the accessory fastener element will remain in the selected position, the accessory coupling member preferably comprises locking means for locking the accessory fastener element in the selected position. Such locking means include clamping arrangements, screws, locking pins, friction increasing elements etc. as known in the art.
The trajectory may extend at least 180°, 220°, 270°, or 300° around the transverse axis and may even extend up to a full 360° revolution around the transverse axis.
By a bicycle accessory is meant any item that a user may wish to attach to a bicycle and in particular to a bicycle handle bar, such as a bicycle bag or bicycle basket, a bottle holder, a mobile phone holder, a bicycle light, a map holder, etc. and further including all types of electronic displays and other electronic equipment for use with a bicycle such as a navigator, a speedometer, an interactive pad, etc.
By a rigid coupling as used herein, is implied a coupling between two elements which coupling inhibits relative movement between the elements during in-use conditions for which the coupling is designed. Accordingly, in a bicycle accessory coupling device of the invention, the coupling between the coupling device and a bicycle handle bar should be a rigid coupling ascertaining that the coupling device remains attached to the handle bar in the same position throughout the use of the coupling device for coupling of one or more accessories to the handle bar.
By a unitary element as used herein, is implied an element that is assembled by a manufacturer and that is delivered to an end user as a single component.
The invention will be described in greater detail with reference to the appended drawings in which:

The accessory coupling member 3 comprises two parallel guiding rails 6 which are curved in the longitudinal direction, L, and arranged at a distance, d, from each other in the transverse direction, T, of the coupling device 1.
The guiding rails 6 form a track to which one or more bicycle accessories 7, 8 may be directly or indirectly attached. In the example shown in
The handle bar coupling member 2 has a transverse axis, At, in a transverse direction of the coupling device. The transverse axis, At, of the handle bar coupling member 2 coincides with the axis of extension of the handle bar 5 in the area where the coupling device 1 is mounted on the handle bar 5. The curved trajectory formed by the guiding rails 6 is shown to extend radially around the transverse axis, At, of the handle bar coupling member 2 and to occupy approximately at least 180° of a full revolution around the transverse axis, At, of the handle bar coupling member 2. Furthermore, the guiding rails 6 are shown to extend further downward on the front side of the coupling device 1 than on the rear side of the coupling device 1, allowing the bicycle bag 8 to be hung at a position below the bicycle handle bar 5 and the electronic interactive pad 7 to be positioned where it can be easily seen and accessed by a rider of the bicycle.
