Frame for receiving a filter element and method for providing
A frame for receiving a filter element includes: a pair of first members and a pair of second members. The first members may be arranged alternately with the second members in the assembled orientation to establish a plurality of joining structures between adjoining members. Each respective joining structure of the plurality of joining structures maintains the adjoining members oriented substantially about a respective axis. The first members and the second members cooperate to define a volume for effecting the receiving.
1. A frame for receiving a filter element; the frame comprising:
a pair of first members, each including tab members which permit said filter element to be slidingly engaged with said first member between said tab members, and at least two receiving structures; and
a pair of second members, each including a base portion, at least one latching insertion structure extending substantially perpendicular to said base portion, and at least two insertion structures extending substantially perpendicular to said base portion;
wherein:
said first members being arranged alternately with said second members in an assembled orientation to establish a plurality of joining structures between adjoining said members;
each respective joining structure maintaining said members oriented substantially about a respective axis;
said first members and said second members cooperating to define a volume for effecting said receiving; and
each joining structure including at least one joining element, said joining element including:
at least one latching structure, said at least one latching structure including said at least one latching insertion structure;
at least two guiding structures, said at least two guiding structures including said at least two receiving structures and said at least two insertion structures; and
wherein said at least two insertion structures are slidingly receivable within said at least two receiving structures.
2. A frame for receiving a filter element as recited in claim 1 wherein each latching structure including at least two portions for effecting a latching relationship between said respective adjoining members.
3. A frame for receiving a filter element as recited in claim 2 wherein a first portion of said at least two portions is integrally formed in one of said adjoining members, and wherein a second portion of said at least two portions is integrally formed in an other of said adjoining members.
4. A frame for receiving a filter element as recited in claim 3 wherein at least one of said at least one first portion presents a ramp structure generally oriented about an initial axis, and wherein at least one said at least one second portion presents a stop portion; said ramp structure being deflected from said initial axis as said ramp structure is urged against said stop portion along an installation path; said ramp structure returning substantially to said initial orientation about said initial axis when said ramp structure is urged past said stop portion along said installation path to an installed orientation; said ramp structure bearing against said stop portion to effect resisting removal back along said installation path when said ramp structure is in said installed orientation.
