Apparatus for clipping filter and coalescer elements on a frame
An apparatus for releasably clipping to a frame an element for removing particulates, impurities, and/or moisture from an air stream, the apparatus preferably comprising: a self-aligning attachment post; a clip which is longitudinally movable on the post; and a locking member which can be pushed inwardly on the post and which interacts with one or more locking tabs in a manner effective for compressing a biasing member and locking the biasing member in a compressed position for holding the clip in engagement with the element. The apparatus preferably also comprises a handle clip on the outer portion of the attachment post which can be pulled and rotated for installing or removing a second element and can be rotated to a second position and released such that the handle clip will automatically hold the second element on the frame.
1. An apparatus for releasably clipping to a frame at least one element for removing particulates, impurities, moisture, or a combination thereof from an air stream, said apparatus comprising:
an attachment post which will extend outwardly from said frame, said attachment post having at least one locking tab thereon;
a clip positionable on said attachment post for clipping said element to said frame;
a locking member positionable on said attachment post; and
a biasing member positionable on said attachment post between said locking member and said clip,
wherein said locking member can be moved longitudinally on said attachment post and will interact with said locking tab in a manner effective for compressing said biasing member and locking said biasing member in a compressed position for holding said clip in engagement with said element and
wherein said locking member can be rotated on said attachment post between a locking position wherein said locking member will engage said locking tab and a compressing and releasing position wherein said locking member will pass over said locking tab.
2. The apparatus of claim 1 wherein said locking member can be operated by hand.
3. The apparatus of claim 1 wherein said clip is longitudinally movable on said attachment post over said locking tab.
4. The apparatus of claim 1 further comprising a retainer securable on said attachment post for preventing said clip, said biasing member, and said locking member from falling off of said attachment post.
5. The apparatus of claim 1 further comprising a base on a proximal end of said attachment post, said base being positionable on a frame member included in said frame and said base being configured in a manner effective for automatically aligning said attachment post in position for clipping said element to said frame member when said base is placed on said frame member.
6. The apparatus of claim 5 wherein said attachment post has a longitudinal axis and said base has two lateral ends which are spaced laterally from said longitudinal axis.
7. An apparatus for releasably clipping to a frame at least one element for removing particulates, impurities, moisture, or a combination thereof from an air stream, said apparatus comprising:
an attachment post which will extend outwardly from said frame, said attachment post having at least one locking tab thereon;
a clip positionable on said attachment post for clipping said element to said frame;
a locking member positionable on said attachment post; and
a biasing member positionable on said attachment post between said locking member and said clip,
wherein said locking member can be moved longitudinally on said attachment post and will interact with said locking tab in a manner effective for compressing said biasing member and locking said biasing member in a compressed position for holding said clip in engagement with said element and
wherein when said locking member is unlocked, said clip can be moved outwardly on said attachment post away from said frame and rotated on said attachment post to an installation and removal position for installing and removing said element.
8. An apparatus for releasably clipping to a frame at least one element for removing particulates, impurities, moisture, or a combination thereof from an air stream, said apparatus comprising:
an attachment post which will extend outwardly from said frame, said attachment post having a plurality of locking tabs provided thereon for installing elements of different thicknesses;
a clip positionable on said attachment post for clipping an element to said frame;
a locking member positionable on said attachment post; and
a biasing member positionable on said attachment post between said locking member and said clip,
wherein said locking member can be moved longitudinally on said attachment post and will interact with said locking tab in a manner effective for compressing said biasing member and locking said biasing member in a compressed position for holding said clip in engagement with said element.
9. An apparatus for releasably clipping to a frame at least two elements for removing particulates, impurities, moisture, or a combination thereof from an air stream, said apparatus comprising:
an attachment post which will extend outwardly from said frame, said attachment post having at least one locking tab therein;
a clip positionable on said attachment post for clipping a first of said elements to said frame on a first lateral side of an outwardly projecting ridge of a frame member included in said frame and said clip also being effective for clipping a second of said elements to said frame on a second lateral side of said outwardly projecting ridge;
a locking member positionable on said attachment post; and
a biasing member positionable on said attachment post between said locking member and said clip,
wherein said locking member can be moved longitudinally on said attachment post and will interact with said locking tab in a manner effective for compressing said biasing member in a compressed position for holding said clip in engagement with said first and said second of said elements and
wherein said clip includes element spacers positionable on each side of said outwardly projecting ridge for spacing said first and said second of said elements from said outwardly projecting ridge.
10. An apparatus for releasably clipping to a frame at least two elements for removing particulates, impurities, moisture, or a combination thereof from an air stream, said apparatus comprising:
an attachment post which will extend outwardly from said frame, said attachment post having at least one locking tab thereon;
a first clip structure positionable on said attachment post for clipping a first of said elements to said frame;
a locking member positionable on said attachment post;
a first biasing member positionable on said attachment post between said locking member and said first clip structure;
a second clip structure positionable on said attachment post for longitudinal and rotational movement;
a retainer securable on an outer end of said attachment post; and
a second biasing member positionable on said attachment post between said second clip structure and said retainer,
wherein said locking member can be moved longitudinally on said attachment post and will interact with said locking tab in a manner effective for compressing said first biasing member and locking said first biasing member in a compressed position for holding said first clip structure in engagement with said first of said elements,
said second clip structure can be pulled outwardly and rotated to a first position for installing a second of said elements over said first of said elements, and
said second clip structure can be rotated to a second position and released such that said second biasing member will urge said second clip structure against said second of said elements for holding said second of said elements over said first of said elements.
11. The apparatus of claim 10 wherein said second clip structure includes a gripping handle.
