" Bicycle handlebars "

Description

Bicycle handlebars, apart from handlebars for sports purposes, do not offer the rider enough grip options . Particularly when riding on changing _terrain , such as mountain biking (climbs, descents, uneven roads) « a constantly adaptable sitting position on the bike is necessary. This is associated with a changing grip position on the handlebars > which cannot be achieved with a more or less shaped but mainly straight handlebar.

This object is achieved by the invention specified in claims 1 to 4.

The following description of an embodiment together with the drawings serves to provide further explanation.

The bicycle handlebar consists of a bracket (1), a slide (2a) » a carrier (2b), a holder (2c) and various fastening elements (3, 4, 5).

Bf is shown in the drawings as sides* and sides as well as joined together in perspective.

Using these parts, the bicycle handlebars can be rotated and moved about the axes described in _the claim. This allows the rider to determine the upper body position that is correct for him and also adapted to the current terrain conditions , which at the same time optimizes the use of force towards the bottom bracket. When riding uphill in particular, when changing from sitting to pedaling (riding standing up), the handlebars must be gripped further forward to achieve a better support angle between arms and body. The U-shaped ends are used for this purpose. The hands also rest on them when riding faster, when the rider adopts a flatter, aerodynamic posture. The brake and gear levers are also located here. The bicycle handlebar adjustment device can be opened and closed using screws or quick-release fasteners at points 3, 4 and 5. The contact surfaces on which the parts 2c and 2a to be changed rest are designed as guides with toothed surfaces to prevent the bracket (1) and the slide (2a) from slipping under heavy loads. The bracket (1) is simply clamped within the mounting hole (6). By pulling the bracket (1) up or down, its inclination is adjusted, and by pushing it forwards or backwards, its distance from the driver is adjusted. The bracket (1) can, but is not manufactured as a closed part in this example * so that the

htj brake and gear levers can be mounted. Ef is designed as a tube and at the ends the holder (2c) is clamped using internal or external fastening methods. The bracket (1) can be changed within the axes and angles described in claim 4. It may therefore also be necessary to change the holder (2c) and the slide (2a). This serves to do justice to all the resulting scientific findings on improving hand and arm posture.

The slide surface W can be used to accommodate information displays such as speedometer, compass.

The bar diameter (d) and the carrier shaft diameter (d ¹ ) correspond to the dimensions commonly used in the two-wheeler market. The bar cross-section can also be designed in any shape that offers additional strength and grip.

The materials to be selected depend on the current or future state of the art technology. Only metal or only plastic can be used, or both can be used in a variety of ways.

The bracket (1) can also be used without a slide (2a) and carrier (2b), whereby a crucial part of the invention, the forward-facing grip position (saddle pedaling on a hill or flat body position at high speed), is retained. To do this, the bracket (1) must be adapted to the corresponding standard of the mounting holes at the mounting point for a standard stem.

All features mentioned in the description and shown in the drawings are essential to the invention even if they are not expressly mentioned in the claims.
