Abstract

A spring loaded filter clamping frame includes a rear frame section which defines an interior space to secure a filter element. The rear frame section includes a projection extending toward the interior space and a rear latch mechanism. A front frame section defines an interior space and is slidably engaged with the rear frame section. An aperture in the front frame section interacts with the projection. A front latch mechanism with a latch mechanism biasing member interacts with the rear latch mechanism. A frame biasing member is located between the rear frame section and the front frame section. The frame biasing member applies a force urging the rear frame section and the front frame section apart, resulting in a filter clamping frame. In further examples, the frame biasing member is a coil spring and the latch mechanisms are hooks.

Claims (39)

1. A spring loaded filter clamping frame including:

a rear frame section defining an interior space, the rear frame section securing a filter element, the rear frame section including:

a projection attached to the rear frame section extending toward the interior space;

a rear latch mechanism;

a front frame section defining an interior space, wherein the front frame section is slidably engageable with the rear frame section, the front frame section securing the filter element, the front frame section including:

an aperture to interact with the projection;

a front latch mechanism to interact with the rear latch mechanism; and

a frame biasing member located between the rear frame section and the front frame section within the interior space defined by each frame section, wherein the frame biasing member applies a force urging the rear frame section and the front frame section apart, resulting in a spring loaded filter clamping frame.

2. The spring loaded filter clamping frame according to claim 1 , wherein the frame biasing member is a coil spring, a first end of the frame biasing member contacting the rear frame section and an opposing second end of the frame biasing member contacting the front frame section.

3. The spring loaded filter clamping frame according to claim 1 , wherein the rear latch mechanism is a fixed hook.

4. The spring loaded filter clamping frame according to claim 1 , wherein the front latch mechanism is a hook, rotatably attached to the front frame section and urged to a neutral position by the latch mechanism biasing member.

5. The spring loaded filer clamping frame according to claim 1 , wherein the rear frame section has an L-shaped cross-section.

6. The spring loaded filter clamping frame according to claim 1 , wherein the front frame section has an L-shaped cross-section.

7. The spring loaded filter clamping frame according to claim 1 , wherein the projection is a lip.

8. The spring loaded filter clamping frame according to claim 1 , further including at least one handle attached to the front frame.

9. A filter including:

a rear frame section defining an interior space, the rear frame section securing a filter element, the rear frame section including:

a projection attached to the rear frame section extending toward the interior space;

a rear latch mechanism;

the filter element including filter media;

a front frame section defining an interior space, wherein the front frame section is slidably engageable with the rear frame section, the front frame section securing the filter element, the front frame section including:

an aperture to interact with the projection;

a front latch mechanism to interact with the rear latch mechanism; and

a frame biasing member located between the rear frame section and the front frame section within the interior space defined by each frame section, wherein the frame biasing member applies a force urging the rear frame section and the front frame section apart, resulting in a spring loaded filter clamping frame.

10. The filter according to claim 9 , wherein the frame biasing member is a coil spring.

11. The filter according to claim 9 , wherein the rear latch mechanism is a fixed hook.

12. The filter according to claim 9 , wherein the front latch mechanism is a hook, rotatably attached to the front frame section and urged to a neutral position by the latch mechanism biasing member.

13. The filter according to claim 9 , wherein the rear frame section has an L-shaped cross-section.

14. The filter according to claim 9 , wherein the front frame section has an L-shaped cross-section.

15. The filter according to claim 9 , wherein the projection is a lip.

16. The filter according to claim 9 , further including at least one handle attached to the front frame.

17. A filtration media apparatus inlet for a gas turbine including:

A rear frame section defining an interior space, the rear frame section securing a filter element, the rear frame section including:

a projection attached to the rear frame section extending toward the interior space;

a rear latch mechanism;

a front frame section defining an interior space, wherein the front frame section is slidably engageable with the rear frame section, the front frame section securing the filter element, the front frame section including:

an aperture to interact with the projection;

a front latch mechanism to interact with the rear latch mechanism; and

a frame biasing member located between the rear frame section and the front frame section within the interior space defined by each section, wherein the frame biasing member applies a force urging the rear frame section and the front frame section apart, resulting in a spring loaded filter clamping frame.
