FIELD OF THE INVENTION
The present invention relates to a door support and method for holding open a door equipped with a hydraulic-type closure having a pair of arms. More particularly, the present invention relates to a new and improved door support having a pair of adjustable channels which are conveniently and easily mounted over and dismounted from the arms of the door closure.
BACKGROUND OF THE INVENTION
The utilization of doorstops and the alike are well known in the art. However, most, if not all, do not allow a user to readily and conveniently mount and dismount the support from the closure arms. Today, many office buildings and other commercial structures are constructed with large, heavy doors having large panels of glass or metal. In some cases, these types of doors are equipped with hydraulic-type closures to control or limit how fast or slow the door closes. Generally, these types of doors can be found at the main entrance, at emergency exits, and at the shipping entrance. Due to the heavy weight and type of construction, these types of doors can be difficult to support in an open position for prolonged periods of time, such as in the case when it is desired to transport heavy packages, furniture and large objects in and out of the main entryway or to clean at or near the door's threshold.
In some instances, the door is propped open using a built-in door stop, which is generally located at or near the bottom of the door or made part of the door closure unit by the manufacturer. Unfortunately, these types of doorstops fail or become out of adjustment over an extended period of time through frequent use. Additionally, certain fire codes prohibit the use of door-open devices that are permanently attached to the door or door hinge by the user as they can prevent the door from being shut or opened quickly during an emergency. While there are certain recognizable problems in the field using such devices, maintenance or delivery personnel may overcome the foregoing problems by inserting a portable, wedge-like device in between the floor and the bottom of the door, or may insert an object, not necessarily dedicated as a door-open device, in between the doorjamb and door, near the door's hinge, which can cause long-term damage to the door and door jamb. Although the wedge-like doorstop may work on some occasions, it may not on other occasions due to the device's tendency to slip about the floor's surface, particularly if it is waxed and/or if the door is jarred from its stationary position. Moreover, a wedge-like doorstop can be easily misplaced or prevent adequate cleaning at or near the door's threshold.
Accordingly, there still remains the need for a door support that is capable of holding a door in an open position at any desired angle as well as allowing for convenient storage on the user. The door support should be relatively inexpensive to manufacture, simple in design, easily placed into position and removed, and not be subject to damage through proper use. The present invention is directed to the foregoing needs as well as to others as explained and described in the following sections.
BRIEF SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a new and improved door support which can be safely and easily placed over and removed from the arms of the door closure.
It is also an object of the present invention to provide a new and improved door support which is simple in construction and inexpensive to manufacture.
It is another object of the present invention to provide a new and improved door support which is capable of holding open a door for a prolonged period of time.
It is yet another object of the present invention to provide a new and improved door support which may be easily and efficiently manufactured and marketed.
An even further object of the present invention to provide a new and improved door support which is of durable and reliable construction.
To achieve these objects, and others, the present invention essentially comprises a new and improved door support for holding open a door equipped with a hydraulic-type door closure having a pair of arms, such invention comprising, in combination: first and second channel members, each having a top side, a hinged wall and latching wall, with both walls extending perpendicular from the top side; a hinge; and an elongate, flexible band equipped with an aperture at one of its ends for passage of a cylindrical pin or threaded bolt. In operation, the channels are placed over the closure arms until the top sides of the first and second channel members completely rests atop of the closure arms. This positioning locks and prevents lateral movement of the closure arms. The extent to which the door is opened is made possible by the adjustable band, which includes an aperture that matches up or aligns to the threaded apertures of the latching wall of the second channel member.
The present invention is particularly advantageous for use with a door equipped with a hydraulic-type door closure having a pair of arms that are separated by a hinge. These advantages are very important to the average delivery person or maintenance personnel interested in economical and useful improvement to holding open a door equipped with a hydraulic-type closure.
There has been described, rather broadly, the more important features of the present invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated.
It is understood that the present invention is not limited in its application to the details of construction and the arrangements of the components set forth in the following description or illustrated in the drawings. The present invention is capable of other embodiments and of being practiced and carried out in several ways. Further, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting the scope of the present invention.
The foregoing objects of the present invention, combined with the various features of novelty which characterize the present invention, are pointed out with particularly in the claims annexed to and forming a part of this disclosure. For a greater understanding of the present invention, reference should be made to the accompanying drawings and descriptive matter in which there is illustrated the preferred embodiment of the present invention.
