Filter cabinet for furnace systems
View Patent ↗A breakdown cabinet for a furnace filter, the cabinet being made up of a frame support member, a base plate, vertical side and end panels joined together to define a generally rectangular housing having a frame support member, one of the end panels having a door way and an upper door panel mounted in the door way and hinged along its lower edge with spring loaded hinges and pivotal side clip members between the door and sides of the door frame or side panels to securely retain the door in a closed position.
1. A breakdown furnace filter housing assembly for use as a three-dimensional self-standing structure, comprising:
a base member, generally rectangular vertical side panels and a pair of opposite, generally rectangular end panels joined to define a generally rectangular housing;
said base member having upwardly directed flanges;
wherein said end panels and said side panels are joined in engagement to said upwardly directed flanges;
a first of said end panels having a doorway and a door panel mounted in said doorway for movement between an open and closed position with respect to said doorway, wherein said first end panel comprises a sheet material comprising an upper frame member, a lower frame member and side frame members connecting the upper and lower frame members wherein the doorway is formed between the upper, lower and side frame members;
a frame brace member secured to each of said end panels, wherein said frame brace member comprises a shelf member;
a pair of removable horizontal guideways mounted to the shelf member with a clip member, wherein the clip member is clipped on to the shelf member such that each of the horizontal guideways extends outwardly from said frame brace member along an interior of said side panels, said guideways each comprising a horizontal top rail and a lower filter frame;
wherein said guideways extend longitudinally in spaced relation to said side panels, thereby forming a gap between said side panels and said frame brace member; and
an open plenum between a horizontal top wall and a top portion of said frame brace member.
2. The furnace filter housing assembly according to claim 1 wherein said frame brace member is defined by opposite side and end members, one of said end members having an extension member.
3. The furnace filter housing assembly according to claim 2 wherein said extension member extends outwardly in a horizontal plane from said frame brace end member.
4. The furnace filter housing assembly according to claim 2 wherein said extension member is in touching relation to an upper surface of a furnace filter.
5. The furnace filter housing assembly according to claim 2 wherein said guideways are removably mounted on said frame brace side members.
6. The furnace filter housing assembly according to claim 1 wherein said guideways include mounting members that extend along a length of said guideways.
7. The furnace filter housing assembly according to claim 1 wherein said guideways are offset from top edges of said open plenum and said guideways comprise said horizontal top wall and formed to engage with a lateral top wall of a filter frame when pressurized in an upward airflow condition, and lower filter frame rails adapted for holding the furnace filter frame along bottom surface edges of the filter frame.
8. The furnace filter housing assembly according to claim 1 wherein said guideways may have different sizes.
