1. Field of the Invention
The present invention relates to a road cone, more particularly to a road cone including light emitting units for warning purposes.
2. Description of the Related Art
Traffic barriers and roadwork barriers are known in which horizontal rails are suspended between upright pots that carry electric lamps powered by electric batteries, for example, dry cell batteries. It is known to mount the lamps at the top of the posts, and the batteries may be inside the posts or external thereto. In either case, known arrangements provide the lamps in units that are separate from the batteries or from containers housing the batteries. Furthermore, experience has shown that the lamp units and batteries can be rather easily removed from the posts by thieves. Moreover, existing plastic cone design consists of a plastic material with a phosphorous dye to reflect its presence at lighted street use only. Dark, isolated streets have insufficient lighting to illuminate the existing plastic cone design in case of car breakdown or accident.
Thus, a lighted road cone solving the aforementioned problems is desired.
The lighted road cone comprises a pentagonal base and an elongate, hollow, pyramidal body extending therefrom. Each face of the pyramidal body has a column of lights extending from the base towards the top of the body. A controller turns the cone lights on and off. Each column of lights includes a pair of red lights near the base, an intermediate pair of blue lights, and then a pair of red lights disposed adjacent the top of the cone. A top dome light may be disposed on the top of the hollow pyramidal body.
These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.
Similar reference characters denote corresponding features consistently throughout the attached drawings.
Referring to
A controller 20 turns the lights 12, 14 on and off. A power cord 26 extends from the controller 20 to a power source for the lights 12, 14. Each column of lights 12, 14 comprises a pair of red lights 12 near the base of the cone 10, an intermediate pair of blue lights 14, and then a pair of red lights 12 disposed at the top of the column.
A top dome light 16 may be disposed on the top of the hollow body 24 and may use the same controller 20 for power control and flash rate control. The controller includes six switches for effecting control over the lights 12, 14, 16. The alternating pattern of lights may continue for the length of the hollow body 24. While a pyramid having a pentagonal base, and therefore five faces, is shown in the drawings, it will be understood that the cone 10 may have a pyramidal body having any number of faces and a base with a corresponding polygonal shape (e.g., triangular, square, hexagonal, etc.). It will also be understood that although the drawings show the columns of lights on each face of the cone 10 having six lights 12, 14 grouped in pairs, the cone faces 24 may have a column including any number of lights 12, 14, which may be grouped in other color patterns.
The lights 12, 14, 16 may be incandescent, neon, compact fluorescent, halogen, or Light Emitting Diodes (LEDs), and may include a translucent cover having the desired light color. Alternatively, the light pattern may comprise any combination of white lights, yellow lights, red lights, and blue lights. The power source may be alternating or direct current (AC or DC). Electronic circuitry in the controller 20 may turn the lights on, turn the lights off, and may also cause the lights to flash or strobe either simultaneously (i.e., turn all lights on and off simultaneously) or sequentially (e.g., flash all lights in a single column on and off simultaneously, then flash all lights in the second column of lights on and off simultaneously, etc., so that each face of the pyramidal cone is lighted sequentially in a 360° pattern) at an exemplary 10 Hz rate. A master key switch 60 may be used to energize or de-energize the entire unit 10. The device 10 may be broken down for storage in the trunk of a car.
