Description

APPARATUS FOR PROVIDING RQflSAFETY FOR CYCLISTS This invention relates to apparatus for providing road safety for cyclists.
Many accidents occur when cyclists approach vehicles from behind in slow moving traffic and the vehicle changes direction slightly, with the result that the cyclist collides with the side of the vehicle and suffers injury or death.
The problem is particularly acute with long vehicles such for example as lorries, buses and coaches. If such vehicles knock a cyclist off a bicycle, then there is a possibility that the cyclist will be run over by the rear wheels of the vehicles. Drivers of vehicles often fail to notice in their rear view mirror that a cyclist is approaching from behind. Especially with long vehicles, a view of the cyclist may be masked by the rear of the vehicle. Since cyclists do not make any noise as they approach a vehicle, there is no possibility of a driver of the vehicle hearing the cyclists.
It is an aim of the present invention to reduce the above mentioned problem.
Accordingly, in one non-limiting embodiment of the present invention *.SS *.... there is provided apparatus for providing road safety for cyclists, which *: apparatus comprises a bicycle, transmitter means provided on the bicycle or on a cyclist when the cyclist is riding the bicycle, a vehicle, receiver means on * *.. the vehicle, and warning means on the vehicle, and the apparatus being such ** *S * * * that the receiver means receives the signals from the transmitter means and causes operation of the warning means only when the bicycle is approaching the rear of the vehicle and the bicycle gets within a predetermined distance from the rear of the vehicle.
The apparatus of the present invention is advantageous in being able to alert the driver of a vehicle to the approaching presence of cyclists.
Accidents between vehicles and cyclists may thus significantly be reduced in number. If the cyclist is carrying a child passenger, the child passenger is also made safer by the apparatus of the present invention. The vehicle may be any vehicle including cars, lorries, vans, buses and coaches. The vehicle may be powered by any means including petrol, diesel or electricity.
The predetermined distance may be 30 -40 metres. Other predetermined distances may be employed.
Preferably, the warning means is an audio and visual warning means.
Such a warning means may emit a sound which changes as the bicycle approaches the rear of the vehicle within the predetermined distance. The sound may be an intermittent sound which increases in frequency of occurrence as the bicycle gets closer and closer to the rear of the vehicle within the predetermined distance.
Alternatively, the sound may be an intermittent sound which changes to a continuous sound as the bicycle approaches the rear of the vehicle within the predetermined distance. The continuous sound may get louder and louder as the bicycle gets closer and closer to the rear of the vehicle within the predetermined distance. Alternatively, the continuous sound may stay the *fl. * S. * . * * S
same as the bicycle gets closer and closer to the rear of the vehicle within the predetermined distance.
Alternatively, the audio warning means may emit a continuous sound which changes to an intermittent sound when the bicycle approach the rear of the vehicle within the predetermined distance.
The visual warning means may provide a light which is continuous or intermittent, for example in the same manner as mentioned above for the sound.
If desired, the warning means may simply be an audio warning means or a visual warning means.
The apparatus of the present invention may include attachment means for attaching the transmitter means to the bicycle or to the cyclist.
Preferably, the attachment means is a quick-release attachment means so that the transmitter means can be removed from the bicycle or the cyclist if desired. Alternatively, the attachment means may be a permanent attachment means.
Usually, the transmitter means will be mounted on a front part of the bicycle. The transmitter means may be mounted elsewhere if desired. The transmitter means may transmit at any suitable frequency, for example a radio wave or infra red frequency. The transmitter means and the receiver * means will normally operate on the same frequency.
* The apparatus may include signal control means for causing the signals from the transmitter means to be directed only forwardly and only over a predetermined narrow angular range so that only vehicles in front of the *. ** * S * S bicycle and likely to have an accident with the bicycle receive the signals via their receiver means. Thus other vehicles will not receive the signals so that the drivers of other vehicles will not receive false alarms. In this way, any driver of a vehicle receiving the signals and hearing the alarm means, will know that it is his or her vehicle only that is being approached by the cyclist.
The apparatus will normally be one in which the receiver means is configured to be unable to receive the signals once the bicycle has passed the vehicle. This again helps to ensure that the drivers of vehicles know that, when they hear andlor see the alarm means, a cyclist is approaching their vehicle and it is not a false alert. Similarly the apparatus will be one in which the receiver means is configured to be unable to.receive signals from on-coming bicycles.
The apparatus may be one in which the transmitter means is battery-operated.
The apparatus may include switch means for enabling the cyclist to turn the transmitter means on and off, thereby saving battery life when the bicycle is not being used.
The apparatus may be sold with or without the battery. Preferably the battery is a rechargeable battery but the battery may alternatively be a non-rechargeable battery. One or more batteries may be used. *1**
Embodiments of the invention will now be described solely by way of example and with reference to the accompanying drawings in which: *r4 Figure 1 shows apparatus of the present invention; * * *fle * se * S

Figure 2 shows a dashboard of a vehicle such for example as the vehicle shown in Figure 1 and with part of the apparatus of the present invention; Figure 3 illustrates how part of the apparatus shown in Figure 2 is able to be viewed by a driver of a vehicle; Figure 4 shows apparatus of the present invention in use of a road occupied by vehicles and cyclists; and Figure 5 shows in block diagram form an electrical circuit for the apparatus of the present invention.
Referring to Figure 1, there is shown apparatus 2 for providing road safety for cyclists. The apparatus 2 comprises a bicycle 4, and transmitter means 6 provided on the bicycle 4. The transmitter means 6 may alternatively be provided on a cyclist 8 when the cyclist 8 is riding the bicycle 4. * The apparatus 2 also comprises a vehicle 10, and receiver means 12 on the vehicle 10. Warning means 14 is provided inside the vehicle 10. The warning means 14 is an audio and visual warning means 14.
The apparatus 2 is such that the receiver means 12 receives signals 16 from the transmitter means 6 and causes operation of the warning means 14 only when the bicycle 4 is approaching the rear 18 of the vehicle 10 and the bicycle 4 gets within a predetermined distance from the rear 18 of the *fl.
":4 vehicle 10. As shown in Figure 1, the predetermined distance is 30 -40 metres, but this distance may be varied as desired, for example in * S *.*** dependence upon the type of vehicle 10. a.. S * *S 05 OS *S O 0 * 0 *
In Figure 1, the vehicle 10 is shown as a lorry. The warning means 14 is shown as positioned in a driving cab 20 so that it can be heard and seen by a driver 22 of the vehicle 10. In slow moving traffic, if the cyclist 8 attempts to get past the vehicle 10, for example by passing between the side of the vehicle 10 and the curb, then the driver 22 will be warned by sound and by sight as to what the cyclist 8 is doing, or is about to do. The driver 22 can then make sure that he does not move inwardly towards the curb and thereby trap the cyclist 8, and possibly cause the cyclist 8 to fall off the bicycle 4 and become injured. Similarly, if the cyclist 8 attempts to pass the vehicle 10 on the outside of the vehicle 10, then the driver 22 can again make sure that he does not trap the cyclist 8 between the. offside part of the vehicle 10 and any adjacent traffic.
Any suitable and appropriate warning means 14 may be employed.
The warning means 14 is preferably such that it emits a sound which changes as the bicycle 4 approaches the rear 18 of the vehicle 10 within the predetermined distance. Preferably, the sound is an intermittent sound which increases in frequency of occurrence as the bicycle 4 gets closer and closer to the rear 18 of the vehicle 10 within the predetermined distance. The warning means 14 also emits a light, which may be continuous or intermittent in the same manner as the sound. S...

public place. The attachment means 24 is shown in Figure 1 mounts the transmitter means 6 to a front part of the bicycle 4.
Referring now to Figures 2 and 3, there is shown a dashboard 26 of a vehicle which may be the vehicle 10 shown in Figure 10 or it may be another vehicle. The dashboard 26 is provided with standard gauges 28, 30, 32, for example a speedometer, an engine revolution counter, and a petrol gauge.
The dashboard 26 is additionally provided with the warning means 14. The warning means 14 is shown with a speaker part 34 and a visual part 36. The visual part 36 is in the form of a flashing light. A driver 38 is able to hear the audio warning via the speaker part 34, and is also able to see the visual warning via the visual part 36. The visual part 36 may be a bulb or other display that becomes illuminated. The viewing of the visual part 36 is effected through a steering wheel 40 as shown.
Figure 4 shows a road 42 having a central reservation 44. On one side of the central reservation 44 are two lanes 46, 48 for receiving traffic moving in the direction of arrows 50. On the other side of the central reservation 44, there are two lanes 52, 54 for receiving traffic moving in the direction of arrows 56. The inside part of lane 46 is defined by a curb 58. The curb 58 forms the edge of a pavement 60. The inside edge of the lane 52 is defined by a curb 62. The curb 62 defines the edge of a pavement 64. The lanes 46, 48, 50, 52 are shown occupied by vehicles 66 and cyclists 68 on bicycles 70.
S. 555 * The bicycles 70 are each shown with a front wheel 72, a frame 74, a rear * wheel 76 and handle bars 78. Each bicycle 70 has a transmitter (not shown) * * * S..

S
which transmits signals 80 as shown. The signals 80 are transmitted over an arc 82 as shown.
The vehicles 66 have two receiver means 83, attached to one each end part of a rear bumper of the vehicles. Each receiver means 83 is able to receive the signals 80, giving a combined arc 84. As can be seen from Figure 4, a driver of a vehicle 66 is able to know when a cyclist 68 is approaching the vehicle 66 on a bicycle 70, irrespective of whether or not the bicycle 70 is on the near side or the offside of the vehicle 66.
Referring now to Figure 5, there is shown an electronic circuit 88 which may be used in the apparatus of the present invention. The electronic circuit 88 comprises a battery 90 which will normally be on a bicycle. The battery 90 powers a transmitter 92 via a switch 94. The switch 94 is an on/off switch, which enables the battery 90 to be isolated so that the apparatus can be switched on only when the bicycle is being used, and thus power from the battery is only being used to power the transmitter 92 when the bicycle is being used. This saves battery life. The battery 90 is preferably a rechargeable battery.
The transmitter 92 is able to transmit signals of a desired frequency, for example radio frequency signals, to two receivers 96, 98. The receiver 96 is attached to a nearside end portion of a rear bumper of a vehicle. The ** receiver 98 is attached to an offside portion of the rear bumper of the vehicle. S....
* The receivers 96, 98 receive power from a vehicle battery 100. The vehicle * battery 100 will usually be the main vehicle battery used for starting the *5*t* * engine of the vehicle. A separate dedicated battery for the receivers 96, 98 *** S... * ..
S *
may however be employed. If a separate dedicated battery is employed, then the battery may be built into a housing for the receivers 96, 98. In this case, there will be no need to break into the wiring of the vehicle in order to obtain power for the receivers 96, 98.
Each receiver 96, 98 is provided with an indicator light 102 which indicates that the receivers 96, 98 are operating. Each indicator light 102 may be attached to its receiver 96, 98 or, alternatively, each indicator light 102 may be positioned elsewhere, for example on a dashboard of the vehicle.
Each receiver 96, 98 is able to receive signals over an arc 104. The transmitter 92 transmits signals over an arc 106. When the receivers 96 and/or 98 receive the signals transmitted by the transmitter 92, then the receiver or receivers 96, 98 activate a visual warning device 108 and an audio warning device 110. The warning devices 108, 110 are preferably positioned on the vehicle dashboard but they may be positioned elsewhere if desired.
The warning devices 108, 110 enable the driver of the vehicle to be both visually and audibly warned of the approach of the cyclist 68 on the bicycle 70.
The receivers 96, 98 may be attached to the rear bumper of the vehicle by any suitable and appropriate means. Thus, for example, they may be stuck in position by adhesive pads, or they may be screwed into position by self-*s'.
tapping screws. Alternatively, clamps may be employed. The receivers 96, 98 * may be positioned elsewhere on the vehicle as may be desired. The *sPse transmitter 92 may be attached to the bicycle via the same or different means * S as those used for attaching the receivers 96, 98. St..
S *..* * .* * * *
Advantageously, the audio warning device 110 is such that it emits an intermittent sound which increases in intensity the nearer the cyclist gets to the rear of the vehicle. Similarly, the visual warning device 108 may flash with an increasing frequency the nearer the cyclist gets to the rear of the vehicle.
When the cyclist is virtually at the rear of the vehicle, then the audible warning device 10 may emit a continuous tone, and the visual warning device 108 may emit a continuous light. Other types of audible and visual warning methods may be employed to indicate the distance of the cyclist from the rear of the vehicle.
It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected. Thus, for example, a different types of transmitter means and receiver means to those shown may be employed. Individual components shown in the drawings are not limited to use in their drawings and they may be used in other drawings and in all aspects of the invention.
