[0049] Now referring primarily to
[0050] As to particular embodiments having a generally rectangular periphery (54), the exhaust aperture element (53) can have an exhaust aperture element width (55) and an exhaust element aperture length (56). The exhaust aperture element width (55) can be in a range of between about 0.25 inches to about 2.0 inches. As to particular embodiments, the exhaust aperture element width (55) can be selected from the group including or consisting of: between about 0.25 inches to about 0.75 inches, about 0.50 inches to about 1.0 inches, about 0.75 inches to about 1.25 inches, about 1.0 inches to about 1.50 inches, about 1.25 inches to about 1.75 inches, and about 1.50 inches to about 2.0 inches.
[0051] The exhaust aperture element length (56) can be in a range of between about 2.0 inches to about 9.0 inches. As to particular embodiments, the exhaust aperture element length (56) can be selected from the group including or consisting of: between about 2.0 inches to about 4.0 inches, between about 3.0 inches to about 5.0 inches, between about 4.0 inches to about 6.0 inches, between about 5.0 inches to about 7.0 inches, between about 6.0 inches to about 8.0 inches, and between about 7.0 inches to about 9.0 inches.
[0052] As an illustrative example, an exhaust aperture element (53) can have a periphery (54) defining a rectangle having an exhaust aperture element width (55) of about 0.625 inches and an exhaust aperture element length (56) of about 4.0 inches.

[0056] As to particular embodiments, the body length (63) of the rectangle defined by the cover element (57) body periphery (61) can be in a range of between about 2.0 inches to about 10.0 inches. The body length (63) of the rectangle defined by the cover element (57) body periphery (61) can be selected from the group including or consisting of: between about 2.0 inches to about 4.0 inches, between about 3.0 inches to about 5.0 inches, between about 4.0 inches to about 6.0 inches, between about 5.0 inches to about 7.0 inches, between about 6.0 inches to about 8.0 inches, and between about 7.0 inches to about 9.0 inches.
[0057] As an illustrative example, a cover element (57) body periphery (61) can define a rectangle having a body width (62) of about 0.625 inches and a body length (63) of about 4.0 inches.
[0058] Now referring primarily to
[0059] Now referring primarily to
[0060] As to particular embodiments, a weight element (68) can be coupled to the cover element (57) to urge the cover element (57) toward the closed condition (65). The weight assembly (68) can include any material having an amount of weight. As an illustrative example, a weight element (68) can be a magnet (69) which, as an illustrative example, can take the form of a magnetic strip. As to particular embodiments, the weight element (68) can be coupled to the cover element (57) by mechanical fasteners, an adherent, hook and loop fastener, or the like, or combinations thereof.
[0061] As an illustrative example, the weight element (68) can take the form of a magnet (69) coupled to the internal surface (70) of the cover element body (58) at a location which positions the weight element (68) within the exhaust aperture element opening (53A). The magnet (69) can be configured to provide a sufficient amount of weight to maintain engagement of the cover element body (58) with the second curved end panel wall (23) when the exhaust air (8) within the chamber (17) comprises a first amount of pressure and disengage from the second curved end panel wall (23) when the exhaust air (8) within the chamber (17) comprises a second amount of pressure sufficient to overcome the amount of weight and move the cover element body (58) toward the open condition (64).
[0062] As to other particular embodiments, the magnet (69) can be coupled to an external surface (32) of the cover element body (58). The magnet (69) can be configured to provide a sufficient amount of weight to maintain engagement of the internal surface (70) of the cover element body (58) with the an external surface (32) of the second curved end panel wall (23) when the exhaust air (8) within the chamber (17) comprises a first amount of pressure and disengage from the second curved end panel wall (23) when the exhaust air (8) within the chamber (17) comprises a second amount of pressure sufficient to overcome the amount of weight and move the cover element body (58) toward the open condition (64).
[0063] As to particular embodiments, the weight element (68) can take the form of a plurality of weight elements (72) which can be combined in various combinations to adjust the amount of weight coupled to the cover element body (58). As to particular embodiments, the plurality of weight elements (72) can be in form of a plurality of magnets (69). The first of the plurality of magnets (69) can be fastened to the external surface (32) or the internal surface (70) of the cover element body (58) (as shown in the example of
[0064] The cover element (57) can disengage from the second curved end panel wall (23) when the exhaust air (8) within the chamber (17) comprises a second amount of pressure resultant from an amount of obstruction to flow of the exhaust air (8) through the filtration material (29) (also referred to as the “obstructed condition”). As an illustrative example, an obstructed condition can result from an obstruction of the exhaust air (8) flowing through the filtration material (29) by a percent amount in a range of between about 50% to about 100%. The percent amount can be selected from the group including or consisting of: between about 50% to about 60%, between about 55% to about 65%, between about 60% to about 70%, between about 65% to about 75%, between about 70% to about 80%, between about 75% to about 85%, between about 80% to about 90%, between about 85% to about 95%, and between about 90% to about 100%.
[0065] As an illustrative example, the amount of weight coupled to the cover element (57) can be adjusted to cause disengagement of the cover element (57) from the second curved end panel wall (23) when the exhaust air (8) within the chamber (17) comprises a greater pressure resulting from the filtration material (29) having an obstructed condition of about 80%, or other selected percentage depending upon the application.
[0066] As to particular embodiments, the cover element (57) can be configured to remain in an open condition (64) until manually returned to the closed condition (65). For example, when a cover element (57) disengages from the second curved end panel wall (23) due to exhaust air (8) within the chamber (17) reaching the second pressure resulting from the filtration material (29) having an obstructed condition of about 80% (or other selected percentage of obstruction), the cover element (57) can remain in the open condition (64), thereby visible to a user and, correspondingly, providing a visual indicator to the user that the filtration material (29) may require maintenance to remove an amount of lint (10) or other obstruction or replacement. Once the filtration material (29) has been maintenanced, the cover element (57) can be manually returned to the closed condition (65) by the user.

[0068] Now referring primarily to
[0069] As can be easily understood from the foregoing, the basic concepts of the present invention may be embodied in a variety of ways. The invention involves numerous and varied embodiments of a lint catching system and methods for making and using such lint catching system including the best mode.
[0070] As such, the particular embodiments or elements of the invention disclosed by the description or shown in the figures or tables accompanying this application are not intended to be limiting, but rather exemplary of the numerous and varied embodiments generically encompassed by the invention or equivalents encompassed with respect to any particular element thereof. In addition, the specific description of a single embodiment or element of the invention may not explicitly describe all embodiments or elements possible; many alternatives are implicitly disclosed by the description and figures.
[0071] It should be understood that each element of an apparatus or each step of a method may be described by an apparatus term or method term. Such terms can be substituted where desired to make explicit the implicitly broad coverage to which this invention is entitled. As but one example, it should be understood that all steps of a method may be disclosed as an action, a means for taking that action, or as an element which causes that action. Similarly, each element of an apparatus may be disclosed as the physical element or the action which that physical element facilitates. As but one example, the disclosure of a “filter” should be understood to encompass disclosure of the act of “filtering”—whether explicitly discussed or not—and, conversely, were there effectively disclosure of the act of “filtering”, such a disclosure should be understood to encompass disclosure of a “filter” and even a “means for filtering.” Such alternative terms for each element or step are to be understood to be explicitly included in the description.
[0072] In addition, as to each term used it should be understood that unless its utilization in this application is inconsistent with such interpretation, common dictionary definitions should be understood to included in the description for each term as contained in the Random House Webster's Unabridged Dictionary, second edition, each definition hereby incorporated by reference.
[0073] All numeric values herein are assumed to be modified by the term “about”, whether or not explicitly indicated. For the purposes of the present invention, ranges may be expressed as from “about” one particular value to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value to the other particular value. The recitation of numerical ranges by endpoints includes all the numeric values subsumed within that range. A numerical range of one to five includes for example the numeric values 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, and so forth. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. When a value is expressed as an approximation by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. The term “about” generally refers to a range of numeric values that one of skill in the art would consider equivalent to the recited numeric value or having the same function or result. Similarly, the antecedent “substantially” means largely, but not wholly, the same form, manner or degree and the particular element will have a range of configurations as a person of ordinary skill in the art would consider as having the same function or result. When a particular element is expressed as an approximation by use of the antecedent “substantially,” it will be understood that the particular element forms another embodiment.
[0074] Moreover, for the purposes of the present invention, the term “a” or “an” entity refers to one or more of that entity unless otherwise limited. As such, the terms “a” or “an”, “one or more” and “at least one” can be used interchangeably herein.
[0075] Thus, the applicant(s) should be understood to claim at least: i) each of the lint catching systems or lint catching devices herein disclosed and described, ii) the related methods disclosed and described, iii) similar, equivalent, and even implicit variations of each of these devices and methods, iv) those alternative embodiments which accomplish each of the functions shown, disclosed, or described, v) those alternative designs and methods which accomplish each of the functions shown as are implicit to accomplish that which is disclosed and described, vi) each feature, component, and step shown as separate and independent inventions, vii) the applications enhanced by the various systems or components disclosed, viii) the resulting products produced by such systems or components, ix) methods and apparatuses substantially as described hereinbefore and with reference to any of the accompanying examples, x) the various combinations and permutations of each of the previous elements disclosed.
