Description

Title: Warning Device
Technical field of the invention
This invention relates to a warning device. More particularly it relates to a warning device to be used by light vehicles in the vicinity of working heavy machinery, such as in an open mining pit.
Background to the invention
The applicant is aware that light vehicles are normally fitted with a warning device to warn heavy machinery operators of the close proximity of the light vehicle. A brightly coloured ball or flag is normally fitted to an end of a pole which extends upward from a vehicle to be visible to such an operator. However, these warning devices are not visible at night and in adverse weather conditions and the aim of this invention is to increase the visibility of the warning device.
General description of the invention
According to a first aspect of the invention there is provided a warning device, which device includes a light to be fitted to a pole extending upwards from a vehicle.
The light may include a body and a plurality of light emitting diodes arranged about the body such that light is emitted at least sideways in all directions, in use.
The warning device may include a pole and a releasably attachable means for attaching the pole to a vehicle. The pole may include a conductor in electrical contact with the light emitting diodes near the free end of the pole and in electrical contact with an electrical contact near the other end of the pole for electrical contact, in turn, with an electrical contact on the releasably attachable means. The electrical contact on the releasably attachable means may be in contact with an electrical power supply.
The releasably attachable means may be a socket, bayonet type attachment means or a clamp for clamping the pole to the vehicle. In each case the contacts on the other end of the pole, the end to be attached, is positioned to make contact with corresponding contacts on the releasably attachable means when the pole is attached.
The warning device may also include a power interrupting unit for intermittently interrupting the power supply to the light emitting diodes to cause the light emitting diodes to flash.
The warning device may also include a transformer unit for transforming the voltage of a vehicle electrical power supply to a suitable voltage required by the light emitting diodes. The device may be connectable to the electrical system of the vehicle so that the device is activated when the key of the vehicle is in an on position, whether the engine is running or not.
The device may further include a flag and/ or reflective material about at least a portion of the pole to increase the visibility of the device during day time.
The light emitting diodes may be high intensity diodes. The high intensity diodes emit a bright beam of light visible during the day. The light emitting diodes are also durable, lightweight and use relatively little energy.
The pole may be resiliently flexible. The pole may be of a fibre reinforced resin. The pole may also be covered by a protective plastic shrink wrap material. The conductor may be wires and may be covered by the protective shrink wrap material. It will be appreciated that the shrink wrap material contributes to the water and weather resistance of the device. The device may also include a motion detector or proximity detector to detect the proximity of a large vehicle upon which the device is activated.
Detailed description of the invention
The invention is now described by way of example with reference to the accompanying drawings.
In the drawings: Figure 1 shows a warning device, in accordance with the invention; Figure 2 shows an exploded view of the warning device.
Referring now to the drawings, the warning device, in accordance with the invention, is generally indicated by reference numeral 10.
The warning device 10 includes a pair of lights 12 spaced apart on a resiliently flexible pole 14, which pole 14, in use, extends upwards from a vehicle (not shown). Each light 12 includes a body 16 and a plurality of high intensity light emitting diodes 18 arranged about the body 16 such that light is emitted sideways in all directions. The warning device 10 further includes a releasably attachable means in the form of a clamp 20, to be fitted to a light vehicle for attaching the pole 14 to a vehicle. The pole 14 includes a conductor 22 in electrical contact with the light emitting diodes 18 near the free end of the pole 14 and in electrical contact with an electrical contact 24 near the other end of the pole 14 for electrical contact, in turn, with an electrical contact 26 on the clamp 20. The electrical contact 26 on the releasably attachable is, in turn, in contact, in use, with the direct current electrical power supply of the vehicle.
The warning device 10 also includes a power interrupting unit 28 for intermittently interrupting the power supply to the light emitting diodes 18 to cause the light emitting diodes 18 to flash. The warning device 10 also includes a transformer unit 30 for transforming the voltage of the vehicle's electrical power supply to a suitable voltage required by the light emitting diodes 18.
The warning device 10 further includes a flag 32 and a reflective material sock 34 about an upper portion of the pole 14 between the lights 12 to further increase the visibility of the warning device 10 during day time.
It shall be understood that the example is provided for illustrating the invention further and to assist a person skilled in the art with understanding the invention and are not meant to be construed as unduly limiting the reasonable scope of the invention.
The applicant believes that the invention provides increased visibility to help lower accidents where light vehicles are used in the vicinity of heavy vehicles. The invention is also durable, use little energy and conveniently removable from the light vehicle when the light vehicle is used for purposes other than in the vicinity of heavy vehicles.
