The present invention relates to a bicycle brake, in particular a bicycle brake that is adapted to be actuated by means of a brake cable.The present invention relates to a bicycle brake, in particular a bicycle brake that is adapted to be actuated by means of a brake cable.

Bicycle brakes are generally known throughout the field of cycling. Some of these brakes are configured to be mounted around a bicycle wheel and are, upon actuation by the brake cable, adapted to contract around the wheel and to clamp a rim of the wheel in between brake pads of the brake. This clamping will induce a frictional force between the brake pads and the wheel, which will slow down the rotation of the wheel, and will therefore induce a deceleration of the bicycle.Bicycle brakes are generally known throughout the field of cycling. Some of these brakes are configured to be mounted around a bicycle wheel and are, upon actuation by the brake cable, adapted to contract around the wheel and to clamp a rim or the wheel in between brake pads or the brake. This clamping will induce a frictional force between the brake pads and the wheel, which will slow down the rotation of the wheel, and will therefore induce a deceleration of the bicycle.

In an effort to increase the braking properties of bicycles, it has been found advantageous to increase the frictional force on the wheel by increasing the clamping force. This can be achieved by the provision of a lever system, through which the force from the cable is transferred towards the brake pads. With a similar clamping force of the cyclist, a higher frictional force between the brake pads and the wheel can be achieved. An example of such a brake with a lever system can be found in US2012/0181120 A1.In an effort to increase the braking properties of bicycles, it has been found to be advantageous to increase the frictional force on the wheel by increasing the clamping force. This can be achieved through the provision of a delivery system, through which the force from the cable is transferred towards the brake pads. With a similar clamping force of the cyclist, a higher frictional force between the brake pads and the wheel can be achieved. An example of such a brake with a liver system can be found in US2012 / 0181120 A1.

A cyclist, in particular a professional cyclist, may use different types of bicycle wheels in his everyday life. Most professional cyclists, for example, use high-profile wheels during races, since those generally have good aerodynamic properties. High-profile wheels are, however, expensive and can be damaged easily. During training, which is mostly done on the open road (instead of on closed roads), a cyclist may use cheaper, more durable, low-profile wheels.A cyclist, in particular a professional cyclist, may use different types of bicycle wheels in his everyday life.

High-profile wheels are, however, expensive and can be damaged easily. During training, which is mostly done on the open road (instead of on closed roads), a cyclist may use cheaper, more durable, low-profile wheels.

It has however been found that high-profile wheels may have a different width than lowprofile wheels. In particular the width of the rims of these wheels may vary between wheels with different profile heights. This may form a problem during braking, since a distance between brake pads of the brakes cannot be changed easily. A spacing between the rim and the brake pads will therefore vary when different types of wheels were to be installed. However, this spacing preferably is kept constant to allow similar braking force and braking characteristics for multiple rim widths.It has, however, been found that high-profile wheels may have a different width than low-profile wheels.

A spacing between the rim and brake pads will therefore vary when different types of wheels are to be installed. However, this spacing is preferably kept constant to allow similar braking force and braking characteristics for multiple rim widths.

Before, this problem was resolved by adjusting the position of the brake cable in the brake. This adjustment, however, must be performed very accurately in order to maintain good braking properties for all occurring rim widths. The adjusting can therefore not be done swiftly during a change of wheels and may require specialist tools.Before, this problem was resolved by adjusting the position of the brake cable in the brake.

Furthermore, there has been a recent trend in cycling to reduce the weight of bicycles. Often, this weight reduction is achieved by fabricating parts of lighter materials, such as fibrereinforced composites (carbon-fibre), instead of the conventionally used metals. These fibrereinforced materials comprise mats of fibres, which provide strength in their direction of alignment, and are bonded together with a cured resin. Also some of the present bicycle brakes are made of fibre-reinforced composite material.Furthermore, there has been a recent trend in cycling to reduce the weight of bicycles.

These fibrereinforced materials include mats or fibers, which provide strength in their direction of alignment, and are bonded together with a cured resin. Also some of the present bicycle brakes are made or fiber-reinforced composite material.

However, in the above-mentioned bicycle brakes with lever systems, higher bending moments may occur within their parts, due to the additional levers. These bending moments require additional strengthening of the parts by means of fibres that are aligned in other directions than those in the conventional brakes. This extra strengthening, with respect to fibre-reinforced conventional brakes, causes the weight of the brakes to increase.However, in the aforementioned bicycle brakes with lever systems, higher bending moments may occur within their parts, due to the additional levers.

Further rotation of the eccentric with respect to the pin is thereby prevented, and the amount of rotation of the eccentric with respect to one of the first main brake arm, the second main brake arm or the support linkages is limited.In an embodiment, the pin within the groove is configured to limit a relative rotation between the eccentric and the one of the first main brake arm, the second main brake arm or the support linkages, at which the pin is arranged.

In an embodiment ofthe brake, the third rotatable sub-connection comprises the eccentric. The eccentric is thereby connected to the second main brake arm and the first support linkage. Recesses around the opening in the bracket of the second main brake arm thereby are the large-diameter eccentric recesses, in which the large-diameter cylindrical portions of the eccentric members are received. Openings in the first support linkage thereby are the small-diameter eccentric openings, in which the cylindrical portions ofthe eccentric members with the small diameter are received.In an embodiment of the brake, the third rotatable sub-connection comprises the eccentric.

Arranging the eccentric in the third rotatable sub-connection provides the advantage in that the third rotatable sub-connection provides the most room to receive the eccentric. When the eccentric were to be arranged in other sub-connections, there would be less space available and the eccentric may need to be dimensioned smaller. Additionally, placement of the eccentric in the third rotatable sub-connection further provides the best accessibility to, for example, adjust the set screw and/or the position of the eccentric.Arranging the eccentric in the third rotatable sub-connection provides the advantage in that the third rotatable sub-connection provides the most room to receive the eccentric.

This embodiment of the bicycle brake according to the invention provides the advantage over prior art bicycle brakes, that the additional bending moments that occurred in various parts of the prior art brakes with lever systems can be reduced and may even be eliminated. As a result hereof, fewer layers of fibre-reinforcement mats need to be applied, which will result in a lower weight of the brake, while keeping similar braking properties as prior art bicycle brakes with lever systems.This embodiment of the bicycle brake according to the invention provides the advantage over prior art bicycle brakes, the additional bending moments that occurred in various parts of the prior art brakes with liver systems can be reduced and may also be eliminated. As a result hereof, fewer layers of fiber reinforcement mats need to be applied, which will result in a lower weight of the brake, while keeping similar braking properties as prior art bicycle brakes with lever systems.

It is remarked that the above bicycle brake probably, but not necessarily, comprises the inventive adjusting member to achieve the above-mentioned advantage over the known bicycle brakes from prior art, for example from US2012/0181120 A1.It is remarked that the above bicycle brake probably, but not necessarily, comprises the inventive adjusting member to achieve the above-mentioned advantage over the known bicycle brakes from prior art, for example from US2012 / 0181120 A1.

An additional advantage of this embodiment of the bicycle brake lies in the fact that, during actuation of the brake to the brake state, the force in the second support linkage is a tensile load. In previous brakes with lever systems, such as in US2012/0181120 A1, however, the second support linkage (or ‘second transfer brake arm’ in the prior art), was loaded in compression during braking operation.An additional advantage of this embodiment of the bicycle brake lies in the fact that, during actuation of the brake to the brake state, the force in the second support linkage is a tensile load.

For fibre-reinforced materials, compressive loading is less favourable, because the fibres will not provide as much strength to the material as they do during tensile loading and may even be prone to buckling. As a result, parts made for tensile loading can be made thinner, and therefore lighter, as compared to parts that are made for loading in compression at the same magnitude.For fiber-reinforced materials, compressive loading is less favored, because the fibers will not provide much strength to the material as they do during tensile loading and may even be prone to buckling.

The first main brake arm and the second main brake arm each comprise a first opening. The main brake arms are adapted to be rotatably mounted on the first shaft, which can be received within the first openings in the main brake arms. When mounted, the main brake arms can be rotated around the shaft, but are prevented from moving with respect to the shaft, in particular from moving axially along the shaft.The first main brake arm and the second main brake arm each include a first opening.

The shaft is adapted to be fixedly mounted to a bicycle frame, such that the first main brake arm and the second main brake arm can be rotated with respect to the frame around the first axis. At the same time, the fixed mounting of the shaft to the frame will prevent relative displacements between the main brake arms and the frame.The shaft is adapted to be fixedly mounted to a bicycle frame, such that the first main brake arm and the second main brake arm can be rotated with respect to the frame around the first axis.

Brake pads are mounted to the first ends of the main brake arms. A friction surface of the brake pads, which is configured to contact the rim, is arranged such, that it faces the rim.

When the brake is arranged in the release state, the first ends of the first main brake arm and the second main brake arm are set at a predefined distance from the rim such, that the frictional surfaces are set at a distance from the rim. A gap between the rim and the friction surface thereby provides free rotation of the wheel through the brake, in between the brake arms.When the brake is arranged in the release state, the first ends of the first main brake arm and the second main brake arm are set at a predefined distance from the rim such, that the frictional surfaces are set at a distance from the rim. A gap between the rim and the friction surface provides free rotation of the wheel through the brake, in between the brake arms.

When the brake is arranged in the brake state, the first main brake arm and the second main brake arm are rotated with respect to each other such, that their respective first ends are moved towards each other and towards the rim. The brake pads, which are mounted at the first ends of the main brake arms, are thereby moved towards the rim as well, until they eventually touch the rim.When the brake is arranged in the brake state, the first main brake arm and the second main brake arm are rotated with respect to each other such, that their respective first ends are moved towards each other and towards the rim. The brake pads, which are mounted at the first ends of the main brake arms, are moved towards the rim as well, until they eventually touch the rim.

Since the brake is configured to be fixedly mounted to the frame, no relative movement will occur between the brake and the frame upon touching of the friction surfaces of the brake pads against the rim. When the brake pads are pressed against the rim, the normal force that is exerted by the brake pads on the rim will induce a frictional force, perpendicular to the normal force. The frictional force between the brake pads and the rim will be directed opposite to the tangential rolling direction of the rim and will therefore reduce the rotational speed of the wheel and will decelerate the bicycle.Since the brake is configured to be fixedly mounted to the frame, no relative movement will occur between the brake and the frame upon touching of the friction surfaces of the brake pads against the rim.

The first main brake arm and the second main brake arm are preferably bent in between their first openings and their first ends, such that they follow a contour of a tyre that is mounted on the rim. The bent shape will provide a brake that is as light as possible, which is, at the same time, sufficiently strong.

In figures 3a, 3b, 4a and 4b, the brake 100 is displayed in various states. In figures 3a and 3b, the eccentric 160 is in a first position. In the first position, a first end 169 ofthe groove 167 abuts the pin 168.In figures 3a, 3b, 4a and 4b, the brake 100 is displayed in various states. In figures 3a and 3b, the eccentric 160 is in a first position. In the first position, a first end 169 of the groove 167 abuts the pin 168.

In the figure 3a, the brake 100 is in the release state, with a distance (AC1R) between the cable mount 118 and the cable seat 145 and a distance (ΔΒ1R) between the brake pads 111, 121. When the brake 100 is arranged from the release state into the brake state, as in figure 3b, the distance (ΔΟ1B) between the cable mount 118 and the cable seat 145 decreases, as a result of the inner cable being pulled into the outer cable. Accordingly, the distance (ΔΒ1B) between the brake pads 111, 121 decreases as well.In the figure 3a, the brake 100 is in the release state, with a distance (AC1R) between the cable mount 118 and the cable seat 145 and a distance (ΔΒ1R) between the brake pads 111, 121.
