Abstract

A cycle tyre pressure adjuster comprises a control unit 5, air solenoid switching valves 2, rotary air valves 3 and an air supply 1 which enable the pressures in the tyres to be altered while the cycle is in motion. Manual and automatic settings are provided for the pressures within the tyres along with a constant monitoring system, e.g. a visual display or an audible signal to allow the tyre pressures to be checked at all times. <IMAGE>

Description

Cvcle Tvre Pressure Adjuster This invention relates to the pressures within bicycle tyres.
Tyre pressure for 'all terrain' cyclists is known to play a very important part in their performance. In order to gain economical results in all conditions, the tyre pressure has to be altered to suit the terrain, which at present can only be carried out by dismounting and adding or subtracting air from the tyres.
This process is slow and inappropriate for professional cycling.
In this invention there is a cycle tyre pressure adjuster comprising of an air supply, a means of controlling the flow of air in and out of the tyres, a means of transferring the air to and from the wheel whilst it is in motion. Also, to enable all this to happen, a control unit is provided with a constant monitoring system which allows all the motions to be monitored at all times.
The components and their positions on this invention will now be described by way of example with reference to the accompanying drawing in which: Figure 1 shows an average 'all terrain bicycle' with the relevant components in position.
Figure 2 illustrates in third angle projection the rotary air valve positioned in the hub of the wheel.
Figure 3 illustrates in cross section the device which prevents the tyre valve from closing.
With reference to the drawing, the invention comprises an air supply 1 (typically CO2 cannisters), connecting air pipes to the electronically controlled air solenoid switching valves 2, and the rotary air valve 3 illustrated in figure 2. This valve has to allow air to enter and exit a tyre (through a device which holds the inner tube valve open 4, whilst the bike is in motion.
All these components are controlled by a main control unit 5. This unit comprises a visual display and a switching circuit to enable adjustment to the air pressures in the tyres, whilst a visual display allows constant monitoring of the pressures within the tyres.

Claims (7)

Claims
1. In this invention there is a cycle tyre pressure adjuster comprising an air supply, a means of controlling the flow of air in and out of the tyres and a means of transferring the air to and from the tyres whilst the wheel is in motion. So, to enable all this to happen a control unit is provided, whilst a constant monitoring system allows all the motions to be monitored at all times.
2. A cycle tyre pressure adjuster, as claimed in claim 1., wherein a control unit is provided where the controlling switches for the air solenoid valves are mounted. They are also provided with an automatic setting and a manual setting.
3. A cycle tyre pressure adjuster, as claimed in claim 2., where the automatic setting for the tyre pressures is provided which operates by pressure being programmed in to enable a one touch adjustment to the pressure.
4. A cycle tyre pressure adjuster, as claimed in claim 1. and 2., where the manual adjustment of the tyre pressures is provided, which operates by holding one of the buttons on until the desired pressure is reached.
5. A cycle tyre pressure adjuster, as claimed in claim 1., wherein rotary air valves are provided (which are illustrated by figure 2) where the hub of the wheel is used as an air tight chamber with air seals preventing the air from escaping. An airway is provided down the centre of the spindle and then into the interior of the hub and then out of the hub into the inner tube by means of an air pipe. This all results in a leak free air joint.
6. A cycle tyre pressure adjuster, as claimed in claim 1. and 5., wherein a component is provided to allow air to enter and exit the inner tube by holding the valve on the inner tube open, as illustrated in figure 3.
7. A cycle tyre pressure adjuster substantially as described herein with reference to figures 1-3 of the accompanying drawings.
