ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to door closers and more particularly to mounting brackets for door closers.
Current state of the art door closers in the commercial market attach to the door or door frame using very similar methods. They all use fasteners to directly attach the door closer to the door or door frame.
One problem with current door closers is that after the mounting holes are drilled into the door, the door closer must be held in place while the fasteners are inserted and tightened. A door closer can weigh as much as 8 to 10 pounds. This heavy weight must be supported while the fasteners are being tightened. This can make the installation difficult.
The foregoing illustrates limitations known to exist in present door closers. Thus, it is apparent that it would be advantageous to provide an alternative directed to overcoming one or more of the limitations set forth above. Accordingly, a suitable alternative is provided including features more fully disclosed hereinafter.
SUMMARY OF THE INVENTION
In one aspect of the present invention, this is accomplished by providing a door closer having at least one engagement member extending from a first part thereof; and a mounting bracket adapted to be attached to one of a door surface or a door frame surface, the mounting bracket having two door closer retaining members thereon, the first door closer retaining member engaging the at least one door closer engagement member, the second door closer retaining member engaging the door closer at a position offset from the door closer pin.
The foregoing and other aspects will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawing figures.
