ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a divider that may be permanent or temporary that is used in the construction of highways and road. It is especially related to a recessed reflector system for such divider to warn on comers of the existence and location of the divider.
BACKGROUND OF THE INVENTION
Presently dividers are usually cast of concrete and have attached to them, either at the point of manufacture or at the place where the divider is to be used some type of reflector to warn on comers of the existence and location of the divider. The attachment of the reflectors, however, to the divider or barrier is such that the reflector protrudes past the outer surface of the divider or barrier in order that it may be seen by on comers. This, however, creates a problem in that the reflector is therefore exposed to damage and breaking away from the divider or barrier. This causes two problems, the reflector can no longer perform their function and on comers are not warned of the existence or location of the divider or barrier. In addition, for the divider or barrier to remain in service at its present site or a future site there is the added expense of replacement of the damaged or broken off reflectors which adds to the over all maintenance or construction of roadways.
It is therefore and object of the present invention to provide a reflector system that is easily seen yet protected from damage or breaking off from the barrier or divider.
SUMMARY OF THE INVENTION
The disadvantages and limitation of the present reflector system for dividers or barriers is overcome by providing a recess in opposing longitudinal ends of the divider or barrier or at some point alone the longitudinal side of the divider or barrier for insertion, at the place of manufacture or at the placement site, the reflector within the divider or barrier. The reflector to be is one that lays flat with the longitudinal surface of the divider or barrier and has a forward and side reflective surface. In this manner the reflector is protected or shielded by the concrete of the divider or barrier on all sides while allowing on comers to see the reflector.
