Description

Title: Cyclist's aid.

Field of invention

This invention concerns cyclist's aids and in particular a device by which a cyclist's intention to turn, especially when turning to the right, can be more readily observed by a following road user such as the driver of a vehicle or another cyclist.

Background to the invention

Motor vehicles and motor cycles normally have illuminated direction indicators such as orange flashing lights, which are readily seen by following road users, who are thereby warned of the intention of the driver's or motorcyclist's intentions.

In general it has not been practical to install such devices on pedal cycles since the electrical power required is not normally available.

In addition flashing lights or illuminated fingers (such as were installed on cars many years ago) could in general only be installed on a pedal cycle on the rear mudguard or to the rear of the seat, and at that height might not be seen by following road users, especially if seated high up in the cab of a lorry or van, or in the relatively elevated driving seat of a 4 x 4 or people carrier.

Object of the invention It is an object of the present invention to provide a direction indicating aid for a cyclist that should normally be visible to a following road user and which either does not require any electrical energy, or only requires minimal electrical energy, to power it.

Summary of the present inventiun

According to one aspect of the present invention there is provided a direction indicating device for a cyclist comprising a sleeve, band, bangle or gauntlet comprising or including on its outside surface a plurality of light emitting diodes and adapted to be fitted around an arm of a cyclist, and a battery connectable to the diodes through wiring and a switch which is operable to supply electric current to illuminate the diodes at least when the arm is lifted to indicate to a following road user that the cyclist intends to change direction.

The diodes may be connected in series or parallel.

The diodes may be arranged in the form of at least one arrowhead or one or more chevrons, and the device is preferably positioned on the arm so that the or each arrowhead or chevron is pointing away from the shoulder and towards the hand, so that when the diodes are illuminated, the or each illuminated arrowhead or chevron points towards the cyclist's hand and away from their shoulder, so that when the arm is raised the or each illuminated arrow or chevron points in the direction which the cyclist intends to take.

The diodes may emit a coloured light and if so preferably all the diodes on the one device produce light of the same colour, although if devices are to be worn on both arms then the diodes in the device for the one arm may be selected to produce a different colour light from those in the device to be worn on the other arm.

The battery may be carried by the cyclist in a pocket in their clothing or in a sachet or sack or compartment formed in or on the sleeve, band, gauntlet or bangle or may be mounted on the bicycle and flexible wiring is provided between the battery and the device.

Where a plug and socket connection is to be incorporated into the wiring, one section of the plug and socket may be attached to or form part of the sleeve, band, bangle or gauntlet.

In the latter even a plug and socket connection may be provided in the wiring so that cyclist can disconnect the device (and themselves) from the battery where this is mounted on the bicycle.

The battery may be a rechargeable battery.

Where the battery is to be mounted on the bicycle it may conveniently be fitted to the underside and or rear of the saddle.

A dynamo, or alternator and charging circuit may be provided on the bicycle to charge a rechargeable battery as the bike is used.

Alternatively a solar panel may be incorporated into the device or the battery or the bicycle to provide a charging current to keep a rechargeable battery fully charged.

Where a solar panel is to be provided this may be incorporated into the device, on the exterior thereof, so that it will be positioned so as to generally face upwards and outwards when the cyclist is in the cycling position with his/her hands gripping the hand grips at opposite ends of the handlebar.

According to an alternative aspect of the present invention there is provided a direction indicating device for a cyclist comprising a sleeve, band, bangle or gauntlet formed from or including at least on its outside surface a material or light emitting device which glows in the dark either due to fluorescence or phosphorescence or a radio active material whose radioactivity causes light to be emitted, and which has a half-life of at least a year, and which is adapted to be attached to the arm of a cyclist so as to be visible to a following road user when the cyclist raises their arm to indicate they are turning.

In one embodiment the device is attached only to the right arm so as to only indicate when the cyclist is turning right.

In another embodiment a device is attached to each arm so that following road users will be warned if the cyclist intends to turn right or left.

In the said other embodiment the light emitting material or light emitting device may be selected so that one colour of light is emitted by the device on the right arm while another different colour is emitted by the device on the left arm.

The device may be adapted to be attached to the cyclists arm by means of pads of Velcro (RTM) one attached to the rear of the material forming the device and the other complementary pad being attached to the cyclists arm.

In one arrangement the latter may be attached to the outside surface of an elastic band which can be slipped over the cycJists sleeve leaving the Velcro (RTM) exposed ready to receive the complementary pad of Velcro (RTM) attached to the rear of the device.

Alternatively the pad may be attached to a strap which has a buckle at one end, and in use can be wrapped around the cyclists arm and the free end of the strap secured using the buckle to form an endless band around the cyclists arm.

According to a preferred embodiment of this alternative aspect of the invention the device may comprise a band which in use is securable around a cyclists arm and has a piece of the light emitting material, or a light emitting device, secured to what in use is the external surface of the band, the piece of material or light emitting device being in the shape of at least one arrowhead or chevron, and the band is fitted to the arm so that the or each arrowhead or chevron is pointing towards the hand and away from the shoulder so that when the arm is lifted the arrowhead or chevron will point in the same direction as the arm and therefore in the direction in which the cyclist intends to turn.

Where a device incorporating either aspect of the invention is to be incorporated into a gauntlet the latter may comprise a glove or may simply comprise the flared sleeve section of a conventional combined gauntlet and glove.

Irrespective of the nature of the light emitting means, the sleeve band bangle or gauntlet may be constructed as a single length of material having means at opposite ends thereof by which they can be joined together to form a continuous loop around the arm or wrist of a cyclist to retain it in position on their wrist or arm.

The joining means may comprise two patches of Velcro (RTM) which when pressed together will become enmeshed in known manner but which can be separated in known manner by peeling one patch from the other.

Alternatively the joining means may comprise a buckle attached to one end and a strap secured to or formed integrally with so as to extend from the other end.

Where a device incorporating either aspect of the invention is in the form of a sleeve the latter may form part of, or be adapted to be secured to, an outer garment to be worn by the cyclist, which may include a cape of the type which is used by cyclists in wet weather, or a tee shirt or jumper or pullover or jacket.
