Abstract

A bicycle centering device consisting of a mounting assembly (5) which can be mounted on the frame or on the fork (1) of a bicycle, a pivot arm (33), which on one end is rotatably and pivotably connected to the mounting assembly (5) and which on the other end is rotatably and pivotably connected to a dial gauge (52), so that a sensor probe (53), the dial gauge (52) and the rim (2) can be brought into contact.

Claims

1. A bicycle centering device, said device comprising:

a mounting assembly (5) adapted to be mounted on the frame or fork of a bicycle, and including a ball pin (30) having a ball-shaped end;

a dial gauge (52) comprising a dial, a dial gauge holder (50), and a sensor probe, said dial gauge holder including a ball pin (60) having a ball-shaped end; and

a pivot arm (33), said pivot arm being rotatably and pivotably connected on one end to said ball pin (30) of said mounting assembly (5) and being rotatably and pivotably connected on the other end with said ball pin (60) of said dial gauge holder (52),

wherein the pivot arm (33) is connected on one end to said ball-shaped end of said ball pin (30) of said mounting assembly (5) and on the other end to said ball-shaped end of said ball pin (60) of said dial gauge holder (50) of the dial gauge (52) to form ball joints (30, 60,

     80), and

wherein the pivot arm (33) is comprised of two parts (33a, b), said two parts being urged together by means of a clamp screw (35), said parts (33a, b) being provided with bore holes for receiving said ball-shaped end of said ball pin (30) of the mounting assembly (5) and said ball-shaped end of said ball pin (60) of said dial gauge holder (50).

2. A bicycle centering device according to claim 1, wherein said dial gauge (52) includes an analog indicator.

3. A bicycle centering device, said device comprising:

a mounting assembly (5) adapted to be mounted on the frame or fork of a bicycle bicycle, and including a ball pin (30) having a ball-shaped end;

a dial gauge (52) comprising a dial, a dial gauge holder (50), and a sensor probe, said dial gauge holder including a ball pin (60) having a ball-shaped end; and

a pivot arm (33), said pivot arm being rotatably and pivotably connected on one end to said ball pin (30) of said mounting assembly (5) and being rotatably and pivotably connected on the other end with said ball pin (60) of said dial gauge holder (52),

wherein the pivot arm (33) is connected on one end to said ball-shaped end of said ball pin (30) of said mounting assembly (5) and on the other end to said ball-shaped end of said ball pin (60) of said dial gauge holder (50) of the dial gauge (52) to form ball joints (30, 60,

     80),

wherein the pivot arm (33) is comprised of two parts (33a, b), said two parts being urged together by means of a clamp screw (35), said parts (33a, b) being provided with bore holes for receiving said ball-shaped end of said ball pin (30) of the mounting assembly (5) and said ball-shaped end of said ball pin (60) of said dial gauge holder (50), and

wherein said mounting assembly is comprised of two clamp arms (10,

     11), which are pivotably connected on one end and free on the other end, and which on their free end are provided respectively with "V" shaped mounting jaws (13 and

     16), and a tightening means comprising a draw rod (20) and associated tightening screw (19), said draw rod being pivotally connected with one clamp arm, said draw rod being provided with threading, and said threading being received in a threaded bore hole in the other of said clamp arms, such that by turning of the tightening screw the clamp arms can be caused to be drawn towards each other.
