The present invention relates a filter mount, and a method of attaching a filter to an HVAC grille, diffuser, or air handling device frame, either before or after the framed device has been installed.
In HVAC systems containing linear bar grilles or diffusers, it is necessary for there to be a method of cleaning or filtering the air moving throughout the system. There is a need to remove dust and airborne particulate. One method of achieving this is through use of air filters or filtration panels that are installed behind linear bar grilles. These filters are usually installed behind an HVAC linear bar grille that is removing air or pulling air from the area. These are known as return air grilles.
Over time, the air filters become clogged with particulate and must be replaced periodically. These filters are available in a wide range of heights, widths and lengths. These filters are readily available in the marketplace.
In some HVAC systems, after installation and operation, for a period of time, additional filters are needed to improve air quality.
It is known in the art that an HVAC system will have as part of its design, an air filtration system. There are numerous methods of filtering air in an HVAC system. One such method is an air filter known as a dust filter. Air filters and dust filters are commercially available. Air filters require replacement. Air filters have different ratings for the level of particulate they remove from the air. Air quality has become critically important since the Covid pandemic.
It is known in the art that an HVAC linear bar grille may have a perimeter frame. A linear bar grille assembly for an HVAC system will consist of linear bars. The perimeter frame may be in the form of an angle, a Z shape, an L shape or a straight bar. A linear bar grille core will have multiple linear bars running the long dimension. The multiple linear bars will be supported and co-joined with one or more cross members. The cross members are perpendicular to the linear bars. A linear bar grille core may be removable from the frame. A linear bar grille core may be removable from the frame to access a filter, damper or the duct.
It is known in the art that an air filter must remain stationary to allow air in the HVAC system to pass through it. An HVAC system air filter must be accessible. An air filter must not move within an HVAC system.
It is known in the art that an HVAC linear bar grille frame will extend into the HVAC opening or duct. It is known in the art that the air circulating within the HVAC system will pass through the HVAC linear bar grille. It is known in the art that air must pass through the filter. It is known in the art that air passing through the filter and HVAC linear bar grille will exert force. It is known in the art that air passing through the filter and HVAC linear bar grille will exert force and that force will vary. It is known in the art that a filter within an HVAC system must remain stationary.
US patent publication 20120047859 relates to a filter clip for holding a filter media over a supply/return/exhaust of an HVAC system that includes a hook portion that secures to a grid of a suspended ceiling system and a filter holding portion that is connected to a hook portion such that the filter holding portion is biased towards the grid and/or a grille. An air filter placed between the filter holding portion and the grid and/or grille is held against the grid and/or grill until, for example, construction is complete or the filter needs to be changed or removed, thereby covering the supply/return and reducing contamination of the HVAC system from construction dirt/debris.
US patent publication 20150075125 relates to a filter frame assembly comprising a perimeter member surrounding a fluid aperture adapted to accommodate a fluid flow from an upstream direction to a downstream direction. The perimeter member comprises a perimeter upstream surface, a perimeter downstream surface, and a perimeter outer surface connecting the perimeter upstream surface to the perimeter downstream surface. A gasket carrier is attached to the perimeter member and comprises a carrier portion facing generally away from the fluid aperture and a first portion sealing member projecting from the carrier outer portion.
The present invention relates to a filter mount that provides a structure to hold a filter in place behind an air handling device, including a framed linear bar grille or diffuser.
The present invention relates to a filter mount that is comprised of a filter capture ledge or angle, and a mount extension. The mount extension supports the angled filter ledge. The filter mount captures an air handling device. It is an object of the present invention for the air handling device to be a framed linear bar grille or a slot diffuser. It is an object of the present invention for the depth of the mount extension to be sufficient to support the thickness of the filter. It is an object of the present invention for the depth to vary. The filter mount is further comprised of a U-clip base. The U clip base has a channel or opening gap where the air handling device frame is inserted. The U-clip base comprises a shorter side and a longer side. The difference in the height of the sides assists with installing the filter mount on an angle.
It is an object of the present invention for a filter to be captured or contained above the filter capture ledge. The U-clip base provides a projection stop for the filter so it can't move up and down. The U-clip base has a larger side, a smaller side and a channel. An attachment device helps hold the air handling device within the channel.
It is an object of the present invention for the filter mount to have a filter capture ledge, and a U-clip base, which has an opening or channel, a longer side and a shorter side, wherein a frame of an air handling device is held within the channel between the sides. It is an object of the present invention for the frame of the handling device to be held by a fastening device placed in a through hole.
It is an object of the present invention for a filter mount having a filter capture ledge, a mount extension, a U clip base, and a smaller side and a larger side each side of the channel. In this configuration the filter mount can be attached to an air handling device on an angle.
It is an object of the present invention for the filter mount to be removed and re-positioned along the air handling device frame.
The present invention relates to a method of attaching a filter to an air handling device frame with a filter mount either before or after the framed device has been installed.
It is an object of the present invention for the filter mount to be designed for framed, air handling devices with removable cores.
It is an object of the present invention for the filter mount to be attached to any air handling device frame.
It is an object of the present invention for the filter mount to be attached to the bottom of an air handling device frame before or after the air handling frame is installed.
