Description

[0001] The present invention relates to a bicycle gearshift, comprising a gear indicator for indicating a gear in which a gearshift of a bicycle is located and an energy source for supplying energy.

[0002] When riding a bicycle in dark environments, visibility of the engaged gear is often limited or nonexistent. This can lead to the user inadvertently shifting into an inappropriate gear, which can impair riding comfort and power transmission efficiency. Therefore, there is a need for an improved gear indicator that ensures clear and reliable visibility even in low-light conditions.

[0003] The object of the present invention is therefore to provide a bicycle gear shift which enables improved visibility of the engaged gear.

[0004] The problem is solved by a bicycle gearshift having the features of the independent claims. Advantageous or preferred embodiments are each subject of a corresponding dependent claim.

[0005] The proposal is for a bicycle gearshift system with a gear indicator for indicating the gear in which a bicycle's gearshift is currently engaged, as well as a power source for supplying power. The bicycle gearshift system includes a lighting element for illuminating the gear indicator. This ensures that the gear indicator is clearly visible even in poor lighting conditions, enabling more precise gear selection and more efficient power transmission.

[0006] It is also advantageous if the bicycle gearshift comprises at least one electrical line, wherein the at least one electrical line connects the power source to the lighting element. This ensures direct and low-loss power transmission, allowing the gear indicator illumination to operate efficiently and reliably.

[0007] It's also advantageous if the bicycle gearshift includes a switch for activating the lighting element. This allows the gear indicator lighting to be switched on as needed, optimizing energy consumption and extending the lifespan of the power source.

[0008] It is also extremely advantageous if the switching element is designed to switch the lighting element on and off and / or to adjust the brightness of the lighting element in steps or continuously. This allows the intensity of the lighting to be adjusted as needed, ensuring optimal visibility of the gear indicator while simultaneously enabling efficient use of the energy source.

[0009] It's also advantageous to position the lighting element laterally relative to the gear indicator. This provides effective illumination of the gear indicator without obstructing the user's direct line of sight. Furthermore, the lateral positioning simplifies installation and allows for easy retrofitting to existing gearshifts.

[0010] It's also advantageous if the lighting element is located, at least partially, within the gear indicator. This creates a space-saving design that protects the lighting element from environmental influences while also allowing for easy installation.

[0011] It is also advantageous if the lighting element is located on the side of the gear indicator facing away from the user, and / or if the gear indicator is at least partially translucent. This ensures uniform and indirect illumination of the gear indicator, thus avoiding reflections and glare for the user and improving readability under different lighting conditions.

[0012] It is advantageous if the energy source is a battery, an accumulator, and / or a dynamo. This enables a flexible energy supply that can be adapted to different requirements. A battery provides a simple, ready-to-use power source with low maintenance requirements. An accumulator enables a rechargeable solution that is cost-effective in the long term. A dynamo ensures a sustainable energy supply that functions independently of battery changes or recharging.

[0013] A particular advantage is offered by using an LED as the lighting element. This creates an efficient lighting solution characterized by low energy consumption, a long service life, and reliable brightness. Furthermore, LEDs are insensitive to vibration, which further improves their suitability for use in bicycle gearshifts.

[0014] A bicycle with a bicycle gearshift is proposed, wherein the bicycle gearshift is designed according to one or more of the preceding claims.

[0015] Further advantages of the invention are described in the following exemplary embodiments. They show, schematically: Fig. 1 a top view of a bicycle gearshift.

[0016] Fig. Figure 1 shows a top view of a bicycle gearshift 1. The bicycle gearshift 1 includes a gear indicator 2 for indicating the engaged gear. The gear indicator 2 is located near the right bicycle handlebar so that it is clearly visible to the user while riding.

[0017] The bicycle gearshift 1 comprises a lighting element 4, which serves to illuminate the gear indicator 2. Furthermore, the bicycle gearshift 1 has a power source 3 that supplies the lighting element 4 with power. The lighting element 4 is arranged, at least partially, within the gear indicator 2, thereby enabling a compact design.

[0018] Furthermore, the bicycle gearshift 1 has an electrical line 5. The electrical line 5 connects the power source 3 to the lighting element 4, thereby ensuring a reliable power supply. In addition, the bicycle gearshift 1 includes a switching element 6, which serves to activate the lighting element 4. The switching element 6 is designed to switch the lighting element 4 on and off.

[0019] Through the Fig.The embodiment shown in Figure 1 provides an efficient and space-saving lighting solution which ensures improved readability of the gear indicator 2, particularly in poor lighting conditions.

[0020] The present invention is not limited to the illustrated and described embodiments. Modifications within the scope of the claims are possible, as is any combination of the described features, even if they are described in different parts of the description or the claims, provided that no contradiction arises with the teaching of the independent claims.
