ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a marker flashlight. In particular, it relates to a flashlight for portability and carriage on a being or a body in a manner which is not hand held.
Many flashlight configurations are known. Additionally, different flashlight configurations are known which can be clipped onto clothing or be used with an animal or pet. The various known flashlights are often not as simple to manufacture as desirable, nor as versatile as necessary for use on or with living beings or with inanimate objects.
The invention is directed to provide a flashlight which minimizes the disadvantages of known marker flashlights.
SUMMARY OF THE INVENTION
By the present invention, there is provided a flashlight which minimizes the disadvantages of known marker flashlights.
According to the invention there is provided a portable marker light intended to be carried on a being or inanimate body in a hands-free manner. The flashlight comprises a body for locating a battery, a light emitting element mounted relative to the body, and a switching element. There is a spring, which when moved under the action of the switching element, permits closure of an electric circuit between a battery and the light emitting element.
There are at least two elements for securing the light to the being or body. There is preferably also a third element for securing the light.
An electric circuit includes circuitry for permitting periodic flashing of the light emitting element, and the light emitting element is preferably an LED. The switching element is at least partly a lens cover for the light emitting element.
The spring includes a helical spring in a base of the housing. A first portion of the helical spring is connectable through a conductive strip to one side of a pair of batteries, and a second portion of the spring is connectable through a conductive strip to a circuit board which is part of the electric circuit. There is also a leaf spring between the top of the pair of batteries, which are arranged in series, and the circuit board.
