Description

FIGURE 6
ROTATABLE HAZARD SIGNAL
Field of the Invention
The present invention relates to a hazard signal for use in providing hazard warnings to oncoming vehicles or pedestrians. In particular, the present invention relates to a non-powered, rotatable hazard signal.
Background
Roads and walkways can be blocked by obstacles or hazards such as fallen trees, immobile or broken down vehicles, scaffolding and other hazards. It is important that signals can be provided to alert pedestrians or oncoming traffic of such obstacles or hazards in order to minimise the risk of harm or accident. A number of signals exist, however these typically require an additional power source and are therefore cumbersome and expensive to manufacture, time consuming to deploy and expensive to operate. Furthermore conventional signals are not necessarily able to be used for multiple or different types of hazards.
Prior Art
US-5196961 discloses a road sign comprising: a frame means having a rotor opening formed in said frame means; a rotor means including a rotor disk rotatably mounted in said rotor opening of said frame means having a retroreflective sheet formed on a first side surface of said rotor disk capable of reflecting an incident light projecting towards said retroreflective sheet on said disk for forming a bright surface on said first side surface, a light-absorptive surface formed on a second side surface of said rotor disk opposite to said first side surface capable of absorbing incident light for forming a dark surface, an upper blade formed on an upper portion of said rotor disk and protruding towards an observer's eyes from said disk, a lower blade formed on a lower portion of said disk and protruding rearwardly from said disk opposite to said upper blade, and a weight formed on a lower portion of said disk; whereby upon an action of a slight wind pressure on said rotor disk, said rotor disk will be pendulously vibrated for helping an initiation of a rotation of said rotor disk, and upon a further action of an increased wind pressure on said disk, said disk will be driven and rotated to first orient said bright surface frontward as effected by said retroreflective sheet on said first side surface of said disk and then subsequently orient said dark surface frontwardly as effected by said lightabsorptive surface on said second side surface, thereby causing a flashing operation by a continuous rotation of said rotor disk when subjected to a wind pressure.
GB-9003132 discloses a wind-driven spinning sign comprising a support, a rotor mounted on the support to spin about an axis, oppositely curved lateral edges being provided along the rotor so that wind having a component towards the rotor induces it to spin, characterised by at least one aperture spaced from the spin axis and providing an air path from a leading to a trailing face of the rotor, air passing through the aperture as the rotor spins tending to brake the spin of the rotor.
US-3210872 discloses a rotating sign device adapted for use in a climatic environment including windy conditions comprising, in combination: a sign support pedestal; an electrical sign rotatably supported by the pedestal; a motor support means; a rotary hydraulic motor having a rotating output shaft and supported by the support means; a hydraulic power fluid source connected to the motor for supplying hydraulic fluid under pressure to operate the motor; relief valve means operably connected between said motor and said fluid source and openable at a preselected fluid pressure, thereby preventing the fluid pressure developed by wind gusts acting on said sign from exceeding the preselected fluid pressure value and damaging said motor or power fluid source; a drive shaft connected to rotate the sign; flexible torque coupling means interconnecting the drive shaft and the output shaft, the flexible torque coupling means being fabricated from a resilient electrically nonconductive material, a plurality of electrically conductive slip rings on the flexible torque coupling, the slip rings being electrically insulated one from the other by the resilient electrically nonconductive material; brush means for making sliding electrical contact with each of the slip rings; electrical circuit means connected to the brush means for supplying electrical power to the brush means; and electrical circuit means interconnecting the slip rings and the electrical sign.

Detailed Description
With reference to Figures, the wind driven rotatable hazard sign 2, 12, 22 comprises a reflective portion 4, 14, 24; a housing 6, 16, 26 configured to support and allow free relative rotation of the reflective portion 4, 14, 24 about a rotation axis; and a connector 8, 18, 28 configured to engage the housing 6, 16, 26 and to provide a fixation point configured for attachment to an item (not shown).
The reflective portion 4, 14, 24 has a substantially circular body portion providing an orange reflective surface on each surface of the body portion. It is however to be understood that the reflective portion may have any suitable shape and the reflective surface may be of any suitable colour such as for example yellow, blue, orange, red or white.
Fins 13,31 extend to either side of the reflective portion towards airflow in use such that the perimeter of the portion has chamfered angles which point in either direction to better catch airflow to rotate the reflective portion. In the illustrated embodiments, fins extend around the periphery of and outwardly from the body portion of the reflective portion 4,14,24.
The housing is formed from injection moulded polypropylene. It is however to be understood that the housing may be formed of any suitable material which is capable of withstanding repeated and long term exposure to environmental conditions.
The housing 6, 16, 26 is in the form of a circular hoop formed from two separable housing portions 7, 17, T1 which are engageable to form the housing. The circular hoop of the housing is dimensioned to extend around and to be spaced apart from the periphery of the reflective portion to enable free rotation of the reflective portion 4, 14, 24 relative to the housing.
The reflective portion comprises a first pair of opposed ends 3, 13, 23 and a second pair of opposed ends 5, 15, 25. The first pair of opposed ends are rotatably engaged to the housing 6, 16, 26. The second pair of opposed ends 5, 15, 25 are configured for free rotation about the rotation axis of the housing.
The housing 6, 16, 26 provides a pair of miniature bearings 9,9',19,19',29,29' located adjacent each of the first pair of opposed ends 3, 13, 26 of the reflective portion to enable rotational movement relative to the housing 6, 16, 26.
The connector 8,18, 28 is connected to the housing 6,16, 26 and is configured to enable the housing to be attached to an item. The connector of the present invention is versatile and enables the housing to be connected to large varieties of items including fallen trees, vehicles or obstacles in the road.
The connector 8,18, 28 may be any suitable connector such as for example a push fit connection 8, a clamp 18, or a suction cup 28.
It is to be understood that the connector may have an adjustable portion such that the angle of rotation of the reflective portion may be adjusted relative to the connector to enable the orientation of the reflective portion to be adjusted so as to optimise impact with oncoming airflow.
In use, the connector 8, 18, 28 is attached to the hazard item. The fins of the reflective portion catch oncoming airflow for example wind or air turbulence. The reflective portion rotates about the rotation axis relative to the housing providing a signal to any passersby.
The sign of the present invention is non-powered and therefore can be used in all circumstances and does not require an additional power supply.
