Steering device with adjustable handle for bicycles

Abstract

Steering device for a bicycle, comprising: a housing (1) that serves as a cargo container and is designed for mounting directly on the fork steerer tube of the bicycle; and o at least one handle element (4), characterized in that o the housing (1) is provided on its side with at least one rotatably mounted eccentric disc (2) on which the handle element (4) is mounted off-center, whereby the handle element (4) can be adjusted in its position, in particular in the longitudinal direction of the bicycle, by rotating the eccentric disc (2) relative to the housing (1).

Description

[0001] The invention relates to a steering device with an integrated cargo container for bicycles. The housing (1) serves simultaneously as storage space and as a supporting element of the steering system by being mounted directly on the fork steerer tube.

[0002] To allow for ergonomic adjustment to the rider, the housing (1) has a rotatable eccentric disc (2) on each of its side walls. The handlebar grip (4) is attached to this disc (2). By loosening the three fastening screws (3), the disc can be rotated. Because the grip is eccentrically (off-center) mounted on the disc, rotating it moves it closer to or further away from the rider (adjusting the "reach") without having to move the entire housing.

[0003] A key feature is the shape of the housing (1). On the rear side facing the rider, the housing has a curved indentation or recess (5). This design ensures that the rider's knees and legs have sufficient freedom of movement while pedaling, while the housing (1) remains stably centered on the steering axis.

[0004] Character description Fig. Figure 1 shows a perspective view of the device according to the invention. The housing (1) is shown in its operating position above the steering axis. The drawing illustrates the position of the lateral eccentric disc (2) with the associated fastening elements (3) and the steering handle (4) mounted thereon. The ergonomic indentation (5) on the rear of the housing is also visible.

[0005] Detailed description of the invention: The housing (1) forms the central load container and serves as a direct interface to the bicycle's steering system. It is mounted directly onto the steerer tube of the bicycle fork via a clamping device (not shown in detail here).

[0006] The laterally mounted eccentric discs (2) allow for mechanical decoupling of the handle position from the fixed position of the load container. Due to the off-center mounting of the handle (4) on the eccentric disc (2), the handle describes a circular path when the disc is rotated. This circular path allows the user to continuously adjust the handle (4) longitudinally (distance to the saddle). The desired position is fixed by the fastening screws (3), which forcefully lock the disc (2) to the housing (1).

[0007] The rear indentation (5) is ergonomically optimized so that it does not restrict the knee's range of motion during pedaling. Despite this recess, the volume of the housing (1) in the front and side areas remains fully available for storage. The combination of centered load distribution and individual grip adjustment ensures stable and safe handling.

Claims

[1] Steering device for a bicycle, comprising: a housing (1) that serves as a cargo container and is designed for mounting directly on the fork steerer tube of the bicycle; and o at least one handle element (4), characterized by , that o the housing (1) is provided on its side with at least one rotatably mounted eccentric disc (2) on which the handle element (4) is mounted off-center, whereby the handle element (4) can be adjusted in its position, in particular in the longitudinal direction of the bicycle, by rotating the eccentric disc (2) relative to the housing (1). [2] Steering device according to claim 1, characterized by , that the adjustability of the handle element (4) allows stepless adjustment of the distance to the rider (reach). [3] Steering device according to claim 1 or 2, characterized by, that the eccentric disc (2) can be locked to the housing (1) by means of several fastening screws (3) in order to fix the set position of the handle element (4). [4] Steering device according to any one of claims 1 to 3, characterized by , that the housing (1) has a curved indentation or recess (5) on its rear side facing the rider, which serves to ensure freedom of movement of the rider's knees when pedaling. [5] Steering device according to claim 4, characterized by , that the indentation (5) is dimensioned and shaped in such a way that it does not restrict the range of motion of the knees during the pedaling motion, while maintaining the maximum volume of the load container (1) in the front and upper area. [6] Steering device according to any one of claims 1 to 5, characterized by, that the combination of the centered mounting of the housing (1) on the steering axle and the individual adjustability of the handle element (4) supports stable and safe driving behavior.
