## Abstract

An interface member is provided for a bicycle brake having a brake arm and another brake arm, wherein the brake arm pivots around a pivot axis, and wherein the other brake arm pivots around another pivot axis. The interface member comprises a mounting portion, a first operating portion and a second operating portion. The mounting portion is structured to be mounted in close proximity to the pivot axis. The first operating portion extends from the mounting portion for interfacing with the brake arm, and the second operating portion extends from the mounting portion and is structured to extend towards the other brake arm. The second operating portion is axially thick.

## Claims

### Claim 1

An interface member for a bicycle brake having a brake arm and another brake arm, wherein the brake arm pivots around a pivot axis, wherein the another brake arm pivots around another pivot axis, wherein the brake arm has an upper portion above the pivot axis and a lower portion below the pivot axis, wherein the another brake arm has an upper portion above the another pivot axis and a lower portion below the another pivot axis, wherein the interface member comprises:
a mounting portion structured to be mounted in close proximity to the pivot axis;
a first operating portion that extends from the mounting portion for interfacing with the brake arm; and
a second operating portion that extends from the mounting portion and is structured to extend towards the another brake arm;
wherein the first operating portion extends downwardly from the mounting portion, and wherein the second operating portion extends above the first operating portion;
wherein the second operating portion is axially thick; and
wherein the second operating portion is axially thicker than the first operating portion.

### Claim 2 (depends on 1)

The interface member according to claim 1 wherein the second operating portion is axially thicker than the mounting portion.

### Claim 3 (depends on 1)

The interface member according to claim 1 wherein the second operating portion has a shape of an axially-thick paddle.

### Claim 4 (depends on 1)

The interface member according to claim 1 wherein the mounting portion includes a mounting opening dimensioned to receive a brake arm pivot shaft therethrough.

### Claim 5 (depends on 4)

The interface member according to claim 4 wherein the second operating portion has a shape of an axially-thick paddle.

### Claim 6 (depends on 5)

The interface member according to claim 5 wherein the first operating portion has a shape of an axially-thin rod-shaped member.

### Claim 7 (depends on 1)

The interface member according to claim 1 wherein the mounting portion, the first operating portion and the second operating portion are formed as a continuous one-piece member.

### Claim 8 (depends on 3)

The interface member according to claim 3 wherein the paddle forms an axially-flattened and axially-broad panel.

### Claim 9

A bicycle brake apparatus comprising:
a brake arm including:
a brake arm mounting portion for mounting the brake arm to a bicycle frame member to pivot around a pivot axis;
a brake pad mounting portion below the pivot axis; and
a control interface portion above the pivot axis;
another brake arm including:
a brake arm mounting portion for mounting the another brake arm to the bicycle frame member to pivot around another pivot axis;
a brake pad mounting portion below the pivot axis; and
a control interface portion above the pivot axis; and
an interface member comprising:
a mounting portion;
a first operating portion that interfaces with the brake arm when the brake arm and the another brake arm are mounted to the bicycle frame member; and
a second operating portion that extends towards the another brake arm when the brake arm and the another brake arm are mounted to the bicycle frame member;
wherein the first operating portion extends downwardly from the mounting portion, and wherein the second operating portion extends above the first operating portion;
wherein the second operating portion is axially thick; and
wherein the second operating portion is axially thicker than the first operating portion.

### Claim 10 (depends on 9)

The interface member according to claim 9 wherein the second operating portion is axially thicker than the mounting portion.

### Claim 11 (depends on 9)

The apparatus according to claim 9 wherein the second operating portion has a shape of an axially-thick paddle.

### Claim 12 (depends on 9)

The apparatus according to claim 9 wherein the second operating portion is structured to be disposed below the control interface portion of the another brake arm when the brake arm and the another brake arm are mounted to the bicycle frame member.

### Claim 13 (depends on 9)

The apparatus according to claim 9 wherein the brake arm is structured to be mounted to the bicycle frame member at a location offset from where the another brake arm is mounted to the bicycle frame member.

### Claim 14 (depends on 11)

The apparatus according to claim 11 wherein the paddle forms an axially-flattened and axially-broad panel.
