1. A filter mounting device for use in an air filtering apparatus which includes a cabinet having at least one filter access door, a filter, and an air outlet for air exiting the filter, comprising:
- a) a first frame having first and second ends and a front and a rear, and adapted to be fixedly secured within the cabinet adjacent the filter access door and beneath the air outlet;
b) a second frame having first and second ends and a front and a rear, disposed beneath the first frame in a spaced relationship with respect to the first frame to define a filter receiving cavity with the second frame adapted to support the filter;
c) a means for substantially simultaneously moving the first and second ends of the second frame upwardly, from a first position which permits a filter to be loosely disposed within the filter receiving cavity, toward the first frame into a second position with the filter disposed in a sealed relationship with respect to the air outlet, including at least cam surface, associated with each of the first and second ends of the second frame;
the cam surfaces permitting relative movement between the second frame and the cam surfaces and causes the second frame to move to, and from, the first position; and
(d) a means for biasing the second frame into the second position, the biasing means being a spring, having first and second ends, disposed at each of the ends of the second frame, the first end of each spring being connected to an end of the second frame, and the second end of each spring being connected to a slide plate.

14. An air filtering apparatus for providing filtered air to an enclosed space, comprising:
-
a) a cabinet, including at least one filter access door; b) an unfiltered air inlet in the cabinet for unfiltered air; c) a filtered air outlet in the cabinet; d) at least one filter disposed in the cabinet, the at least one filter having an air inlet and an air outlet associated therewith in the cabinet; e) a blower disposed in the cabinet for drawing unfiltered air from the unfiltered air inlet, through the at least one filter and outwardly through the filtered air outlet; f) a filter mounting device disposed in the cabinet, the filter mounting device including a first frame, having first and second ends and a front and a rear, fixedly secured within the cabinet adjacent the at least one filter access door and beneath the air outlet associated with the at least one filter;
a second frame, having first and second ends and a front and a rear, disposed beneath the first frame in a spaced relationship with respect to the first frame to define a filter receiving cavity with the at least one filter being disposed upon, and supported by, the second frame; and
a means for substantially simultaneously moving the first and second ends of the second frame upwardly, from a first position which permits the at least one filter to be loosely disposed within the filter receiving cavity, toward the first frame, into a second position with the at least one filter disposed in a sealed relationship with respect to the air outlet, including at least one cam surface, associated with each of the first and second ends of the second frame;
the cam surfaces permitting relative movement between the second frame and the cam surfaces and causes the second frame to move to, and from, the first position; and(g) a means for biasing the second frame into the second position, the biasing means being a spring, having first and second ends, disposed at each of the ends of the second frame, the first end of each spring being connected to an end of the second frame, and the second end of each spring being connected to a slide plate. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A filter mounting device for use in an air filtering apparatus which includes a cabinet having at least one filter access door, a filter, and an air outlet for air exiting the filter, comprising:
-
a) a first frame having first and second ends and a front and a rear, and adapted to be fixedly secured within the cabinet adjacent the filter access door and beneath the air outlet; b) a second frame having first and second ends and a front and a rear, disposed beneath the first frame in a spaced relationship with respect to the first frame to define a filter receiving cavity with the second frame adapted to support the filter; c) a means for substantially simultaneously moving the first and second ends of the second frame upwardly, from a first position which permits a filter to be loosely disposed within the filter receiving cavity, toward the first frame into a second position with the filter disposed in a sealed relationship with respect to the air outlet, including at least one cam surface, associated with each of the first and second ends of the second frame;
the cam surfaces permitting relative movement between the second frame and the cam surfaces and causes the second frame to move to, and from, the first position; and(d) the moving means further includes a means for actuating the moving means to provide relative movement between the second frame and slide plates disposed at both ends of the first and second frames and the actuating means is at least one handle connected to each of the first and second ends of the first frame, the at least one handle having an upper and a lower end, the upper end of the at least one handle being pivotally connected to at least one of the ends of the first frame, and the lower end of the at least one handle connected to one of the slide plates whereby upon rotation of the at least one handle, with respect to the first frame, relative movement is provided between the second frame and the cam surfaces of each slide plate to cause the second frame to move to, and from, the first position. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
