Definitions

  • the present invention relates to an indicator light device for a vehicle with handlebars.
  • the present invention also relates to a navigation device for a vehicle with handlebars.
  • Cyclists often use arm signals to indicate that they are turning left or right. These are poorly visible, if at all, when cycling at night or in situations with low visibility. This makes it difficult and hazardous for cyclists to turn off or into a road, because other road users are not aware of the cyclist's intention. Many cyclists do not indicate their intended turning direction at all and some cyclists fall off their bicycles when they do.
  • Cars, motorbikes and other motorised vehicles have indicator lights positioned on the left and right hand sides of the front and back of the vehicle, and operated by the driver from a control on the dashboard.
  • the control is connected to the indicator lights by an electric circuit powered by the car's battery.
  • a driver wishing to turn left operates the left indicator switch, causing the indicator lights on the front left and back left of the car to flash repeatedly.
  • the signal is recognised by other road users and pedestrians.
  • the indicator button is switched off.
  • Cars have also been developed in which the indicator is switched off automatically when the steering wheel turns in the opposite direction (i.e. when the indicated turn has been completed).
  • an indicator light device suitable for a vehicle with handlebars, the indicator light device comprising: a gripping unit arranged to be gripped by a user's hand, the gripping unit having an elongated tubular body for fitting over a handlebar, the gripping unit comprising an actuation unit operable by the user's hand; an indicator unit attached to the gripping unit, the indicator unit including an indicator light arranged to emit light for indicating turning direction of the vehicle, the indicator light being controlled by the actuation unit.
  • the actuation unit comprises a button arranged to turn the indicator light on when pressed, wherein the indicator light is arranged to be turned off when the button is pressed again or after a predetermined time.
  • the indicator light is on, the indicator light is arranged to pulse light at 1-2 Hz.
  • the indicator unit and the gripping unit are integrally formed.
  • the indicator unit and the gripping unit are releasably engageable.
  • the indicator light device further comprises a connecting member for releasably engaging the indicator unit and the gripping unit.
  • the connecting member is a retaining boss at which a portion of a first fitting mechanism of the indicator unit is accommodated, the retaining boss having an inner screw thread arrangement that is releasably engaged with an outer screw thread arrangement at an end of the gripping unit.
  • the first fitting mechanism is arranged at the indicator unit and a second fitting mechanism is arranged at the gripping unit, the first fitting mechanism and second fitting mechanism being configured to be releasably engageable.
  • the first fitting mechanism is a magnetic ball joint and the second fitting mechanism is a magnetic socket.
  • the indicator unit comprises a pattern light unit arranged to emit light downwards so as to form a predetermined visible pattern on the ground when the vehicle is in use. In some embodiments, the pattern light unit is arranged to form the predetermined visible pattern when the indicator light is turned on.
  • the predetermined visible pattern is arranged to vary over a time period so as to show the intended turning direction of the vehicle.
  • the predetermined visible pattern is an arrow shape arranged to vary in length to show the intended turning direction of the vehicle.
  • the indicator light device further comprises a vibration unit arranged to vibrate the gripping unit.
  • the vibration unit is arranged to vibrate when the indicator light is on. In some embodiments, the vibration unit is arranged to vibrate at the same frequency as that of the indicator light.
  • the gripping unit comprises a sleeve arranged to be slid over the end of the handlebar.
  • the sleeve may be flexible.
  • a retaining clip may be fixed to the handlebar, for example using a clamp, bolts, or other semi-permanent fixing means.
  • the gripping unit which maybe a sleeve, may be adapted to be fastened to the handlebar by means of the retaining clip.
  • the entire indicator light device including the gripping unit and the indicator unit can be conveniently and easily removed, for example to charge the batteries and to prevent theft when the bicycle is left unattended.
  • the semipermanently attached retaining clip ensures that the gripping unit is firmly attached when in use.
  • the position of the retaining clip on the handlebar can be adjusted by loosening the fixing means, moving the retaining clip and then re-tightening the fixing means.
  • the adjustment allows for the gripping unit to be rotated relative to the handlebar, and then fixed in a preferred rotational position. Therefore, the user is able to position the gripping unit to put the controls in a preferred position to suit both the shape of the handlebars of the specific bicycle, and also the user's preferred riding position. Rotating the gripping unit also serves to adjust the direction of the indicator unit, when attached to the gripping unit.
  • the angle of the indicator unit relative to the gripping unit is adjustable, for adjusting the direction in which the indicator light(s) point relative to the bicycle.
  • the angle is adjustable, for example at least 30 degrees either side of a direction substantially perpendicular to the handlebar where the gripping unit is attached.
  • Different bicycles will have handlebars which are angled in different positions relative to the direction of travel of the bicycle, and so this flexibility allows the indicator lights to be positioned for the best visibility, on a wide range of bicycles.
  • an axis of the indicator unit when attached to the gripping unit, extends substantially below the handlebar and to the side of the bicycle (i.e. beyond the end of the handlebar).
  • the vertical angle between the indicator unit and the handlebar may be, for example, around 45 degrees. In this way, the indicator unit sits away from the end of the handlebar, and avoids obstructing the area directly underneath the handlebar.
  • the pattern light unit may include an emitter which points along the axis of the indicator unit, for example around 45 degrees from the vertical. This projects a pattern on the road surface a little way to the side of the bicycle.
  • the indicator unit has a casing including a protective buffer portion.
  • the buffer portion may be in the form of a local thickening of the casing, or may include a separate part attached to the casing.
  • the buffer may clip on, or may be in the form of a sleeve to slide over the indicator unit. It is common to lean bicycles against walls when not in use, and the buffer portion provides the indicator unit with protection when this is done.
  • the gripping unit comprises two case portions that are arranged to be secured around the handlebar.
  • the indicator unit further comprises front and/ or back lights, wherein the front and/ or back lights are controlled independently of the indicator light.
  • the indicator light comprises a front-facing indicator light and/ or a back-facing indicator light.
  • an indicator light comprising a front-facing indicator light and/or a back- facing indicator light also includes at least a portion of indicator light which is visible from the side.
  • the housing of the indicator unit includes a transparent front portion which allows light from the indicator light to escape from the front of the housing to be viewed from the front.
  • the transparent front portion may extend around a corner of the indicator unit, at least on one side, so that light from the indicator light may also be visible from the side.
  • the indicator light device includes a left gripping unit and a left indicator unit for a left handlebar, and a right gripping unit and a right indicator unit for a right handlebar.
  • the indicator light device further comprises a communication system arranged to receive navigation data from an external device, the navigation data including turn directions; wherein the communication system is arranged to control the left and right vibration units to vibrate based on the navigation data received from the external device so as to indicate an upcoming turning direction.
