Description
- 1) Field of the Invention
- The present invention relates to ventilation control of a confined space, and more particularly, to a ventilation control cover placed over an entryway that is adjustable to accommodate different size openings of entryways and which still allows ingress and egress through the entryway without having to completely remove the ventilation control cover from the entryway.
- 2) Description of Related Art
- Ventilation of an enclosed space is of particular concern for a variety of industries and has resulted in a plethora of systems and arrangement to control airflow through a given space. In the home construction field, being able to adequately ventilate and control the flow of air through a confined attic space or crawlspace is critical to the health and safety of the workmen, as well as the homeowner. For example, when installing blown insulation in an attic, the temperature in the attic may be well over 120° F. At such temperatures, without supplemental ventilation the workmen only have minutes to work on installing the insulation before they are forced to exit the space and cool down. A few other examples of situations that typically require ventilation during the project include HVAC service and installation, painting, and spray foam insulation. These type of projects can additionally create off gassing issues and dust problems that pose health hazards to persons and animals in the area, which must be controlled. By ventilating the space, be it an attic, crawlspace, or other generic confined space such as an interior room, the workmen can complete the task more efficiently and in a safer manner.
- An issue with trying to ventilate a space such as a crawlspace or attic is the installation of an appropriate airflow control system. Traditionally, a blower unit with a ventilation hose is attached to an available exterior vent. This can be problematic as the exterior of the structure is not adapted to receive the ventilation hose, which leads to problems in establishing a sufficient airflow to circulate new air into the space.
- Accordingly, it is an object of the present invention to provide a ventilation control cover adapted to be placed over an entryway to a confined space that is adapted for receiving a ventilation hose connected to a blower unit.
- It is a further object of the present invention to provide a ventilation control cover that is easily installed in the entryway and can be quickly removed.
- It is a further object of the present invention to provide a ventilation control cover that maintains access through the entryway while the ventilation cover is in place.
- It is a further object of the present invention to provide a ventilation control cover that is adjustable to accommodate different size openings of entryways.
- The above objectives are accomplished according to the present invention by providing an entryway ventilation control cover comprising a primary cover plate for positioning over at least part of an entryway; a primary ventilation port included in the primary cover plate for directing airflow through the entryway, wherein the primary ventilation port includes a ventilation hose connector adapted for receiving a ventilation hose to draw air through the primary ventilation port; a first side securing plate extending generally perpendicular to the primary cover plate for being secured to a first framing member defining a portion of the entryway; a secondary cover plate slidably carried by the primary cover plate so that the secondary cover plate can be extended and retracted to accommodate different entryway size openings; a second side securing plate extending generally perpendicular to the secondary cover plate for being secured to a second framing member defining a portion of the entryway; and, a flexible sheet carried by the primary cover plate and being extendable to cover a portion of the entryway adjacent the primary and secondary cover plates to resist air flow through the entryway.
- In a further advantageous embodiment, at least one releasable connector is provided for securing the flexible sheet to the primary cover plate.
- In a further advantageous embodiment, at least one secondary port is disposed in the primary cover plate, wherein the secondary port includes a removable port cover to resist airflow through the secondary port when not in use.
- In a further advantageous embodiment, an electrical outlet is carried by the primary cover plate for providing power to electrical equipment through the entryway.
- In a further advantageous embodiment, the ventilation hose connector includes a connecting collar disposed on a bottom side of the primary cover plate adapted for receiving a ventilation hose.
- In a further advantageous embodiment, the ventilation hose connector includes a tapered upper collar interconnecting the connecting collar to the bottom side of the primary cover plate for funneling air from the primary ventilation port through the connecting collar.
- In a further advantageous embodiment, opposing channels are disposed generally at opposite edges on a bottom side of the primary cover plate receiving the secondary cover plate in sliding engagement.
- In a further advantageous embodiment, a light unit is carried by the primary cover plate for illuminating areas adjacent the ventilation control cover.
- In a further advantageous embodiment, the flexible sheet includes a series of releasable connectors carried on a bottom side of the flexible sheet for cooperating with a complementary releasable connector mounted to framing members defining the entryway.
- The above objectives are further accomplished according to the present invention through a system for controlling airflow through an entryway, the system comprising a primary cover plate for covering at least part of an entryway; a primary ventilation port included in the primary cover plate for directing airflow through the entryway; a ventilation hose connector disposed in the primary ventilation port; a secondary cover plate slidably carried by the primary cover plate so that the secondary cover plate can be extended and retracted to accommodate different entryway size openings; a flexible sheet carried by the primary cover plate and being extendable to cover a portion of the entryway adjacent the primary and secondary cover plates to resist air flow through the entryway; a ventilation hose releaseably secured to the ventilation hose connector; and, a blower unit connected to the ventilation hose moving air through the primary ventilation port and the ventilation hose for controlling airflow through the entryway to ventilate the area entered through the entryway.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings forming a part thereof, wherein an example of the invention is shown and wherein:
