Patent Application

This invention relates to door stops, more particularly, a height adjustable door stop that may be adjusted to accommodate the step down from the threshold of a door to a surface beneath the threshold.
Door stops are used to prop doors open and prevent doors from closing. Currently, door stops are available that attach to the base of a door and fold down. A problem with these and other types of door stops is that they do not accommodate doors which have high thresholds or large step downs from the base of the door frame to a surface, such as a step. For example, if a door opens onto a porch that is six inches below the threshold of the door then a user would need a longer than average door stop to prop the door open. Although, door stops are available that are long enough to accommodate larger step downs, these door stops are aesthetically unpleasing when mounted to the base of a door due to their large size.
Therefore, a need exists for an adjustable door stop that is aesthetically pleasing and will accommodate a large range of heights between the threshold of a door and a surface.
The relevant prior art includes the following references:
The primary object of the present invention is to provide an adjustable door stop that can accommodate a large range of step down heights.
Another object of the present invention is to provide an adjustable door stop that is compact when folded up and not in use.
An even further object of the present invention is to provide an adjustable door stop that is aesthetically pleasing when mounted on the base of a door.
The present invention fulfills the above and other objects by providing an adjustable door stop that mounts to the base of a door. The door stop comprises a bracket that is mounted to the base of a door and a tubular section that may be pivotally or hingedly attached to the bracket so that the tubular section may be folded up into the bracket when the door stop is not in use and down when the door stop is in use. Clips located on the bracket hold the tubular section in place while the tubular section is folded up into the bracket. An extendable rod inserts into the tubular section and may be extended out of the tubular section to accommodate various heights of step downs or retracted into the tubular section when the tubular section is folded upward for storage. A lever on the tubular section engages a series of ridges located on the extendable rod to lock the extendable rod in place when the extendable rod is extended and in use. A small protrusion is located on the bracket and comes into contact with the lever when the tubular section is folded upward into the bracket thereby disengaging the lever from the series of ridges located on the extendable rod allowing the extendable rod may be retracted into the tubular section. A cap, preferably made of rubber, is attached to the extendable rod and provides traction between the door stop and the floor.
The above and other objects, features and advantages of the present invention should become even more readily apparent to those skilled in the art upon a reading of the following detailed description in conjunction with the drawings wherein there is shown and described illustrative embodiments of the invention.
