Interface Air Filter and Assembly
Abstract
An air filter retention interface for use with an internal
combustion engine is disclosed. The interface is substantially
secured in an opening of a wall and the interface attaches to an
air filter at the front end of the interface and an air intake tube
on the back end of the interface. The interface has a filter sleeve
and a filter base. During operation of the engine the filter sleeve
is disposed through the opening in the wall such that the wall is
between beads disposed on the external surface of the filter sleeve
and the filter base thereby substantially securing the interface in
place and the front end of the filter base is attached to the
filter and the back end of the filter base is attached to the air
intake tube and air passes through the filter then through the
filter base and filter sleeve and then into the air intake tube and
toward the engine.

contents of both applications are herewith incorporated by

benefit of the applications identified above.
FIELD OF THE INVENTION
[0002] This invention generally relates to air filters for use with
internal combustion engines.
BACKGROUND OF THE INVENTION
[0003] Air filters are critical components for internal combustion
engines. The filter performs the function of removing debris from
the air as the air is transferred into the engine. This reduces
contamination that would otherwise enter the engine. In turn, the
cleaner air allows the engine to run more efficiently and reduces
wear that can occur with the introduction of particulate matter in
the combustion process.
[0004] There are a variety of techniques used to secure the filter
in proximity to the engine. However, the existing techniques tend
to be difficult to use when installing or replacing the filter.
What is needed is a more efficient technique for installing or
replacing the filter.
SUMMARY OF THE INVENTION
[0005] In accordance with the present disclosure, an air filter
retention interface for use with an internal combustion engine is
provided. In one embodiment, the interface is substantially secured
in an opening of a wall and the interface attaches to an air filter
at the front end of the interface and an air intake tube on the
back end of the interface.
[0006] The interface has a filter sleeve having an internal
surface, an external surface, an outer radius, and a front and back
ends.
[0007] The external surface of the filter sleeve has beads
extending above the external surface and disposed substantially
along a circumferential line extending around the external
surface.
[0008] There is an filter base having an outer radius greater than
the outer radius of the filter sleeve and the filter base having an
opening and the filter base is attached to the front end of the
filter sleeve;
[0009] During operation of the engine the filter sleeve is disposed
through the opening in the wall such that the wall is between the
beads and the filter base and the interface is substantially
secured in place and the filter base is attached to the filter and
the back end of the filter sleeve is attached to the air intake
tube and air passes through the filter then through the filter
sleeve and then into the air intake tube and toward the engine.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The invention is generally shown by way of reference to the
accompanying drawings in which:
[0011] FIG. 1 is a side view of the elements of one embodiment of
an air filter retention interface;
[0012] FIG. 2 is a side view of one embodiment of the air filter
retention interface, filter, wall, and air inlet tube; and
[0013] FIG. 3 is a side view of one embodiment of the air filter
retention interface, filter, wall, air inlet tube, and clamp.
DETAILED DESCRIPTION OF THE INVENTION
[0014] FIG. 1 shows an embodiment of the air filter retention
interface 10. There is a filter sleeve 12 having an internal
surface 14 and an external surface 16. The filter sleeve also has a
back end 18 and a front end 20. The filter sleeve is basically a
tube that can be fitted over another tube to some degree such as an
engine air intake tube. In one embodiment, the filter sleeve is
somewhat flexible. Other embodiments can include a more rigid
structure. On the external surface 16 there are beads 22 that
roughly are along a line 24 and the beads are thus substantially
along a circumferential line around the external surface of the
filter sleeve. There is also a filter base 26. In this embodiment,
the filter base is not attached to the filter.
[0015] Turning to FIG. 2, the filter base 26 attaches to the front
end of the sleeve. The base 26 also attaches to the filter 28. The
filter base 26 has a passage that allows air to flow between the
filter 28 and the filter sleeve 12. The filter 28 has input ports
30 where air enters and is filtered. There is also an output port
32 inside the filter where the filtered air can be directed away
from the filter 28.
[0016] In one embodiment, the beads 22 are made of a relatively
flexible material such as rubber. In use, the filter sleeve 12 is
attached to the base 26. The sleeve is placed through an opening 36
in the wall 34. The wall 34 may be a part of a filter housing
chamber or another structure possibly within an engine compartment
that can provide support for the interface. The opening 36 is large
enough to allow the filter sleeve 12 to pass and would normally not
allow the beads 22 to pass is the beads 22 and base 26 were rigid.
Since the beads 22 are somewhat flexible, the beads 22 and filter
sleeve 12 structure can pass through the opening 36. The wall then
abuts the filter base 26 on one side and the beads 22 on the other.
This relatively secures the interface 10 in place. It should be
appreciated that the geometry and number of the beads 22 can be
chosen to fit any particular application desired and is not limited
to those in the figures. In another embodiment, the filter sleeve
12 can also be somewhat flexible. The number and geometry of the
beads 22 can vary. The beads 22 have a surface that contact the
wall of the filter housing chamber. In other embodiments the beads
22 may no be a relatively flexible material and may be
substantially rigid.
[0017] FIG. 2 also identifies an air inlet tube 38. The air inlet
tube 38 passes through the back end 18 of the filter sleeve 12. The
tube 38 can extend through the sleeve 12 and filter base 26 into
the filter 28. However, the depth of penetration of the tube 38 can
be a function of any particular application. Also, while it may
appear that the attachment end of the filter may be generally
circular in shape, filters of other attachment end geometries and
structural geometries are used in other embodiments.
[0018] Turning to FIG. 3, a clamp 40 as well known in the art is
identified. The clamp 40 extends circumferentially around the
filter sleeve 12. The air intake tube 38 extends far enough into
the sleeve 12 so that the clamp 40 can force the filter sleeve 12
against the tube 38 thereby substantially securing the tube 38 in
place. The clamp 40 forces the internal surface 14 of the filter
sleeve 12 against the tube 38.
[0019] As FIG. 3 also indicates, the filter sleeve 12, filter base
26 and filter 28 can be combined to form a single structure. The
sleeve 12 and beads 22 can still be passed through the opening 36
in the wall 34. In other embodiments, the filter base 26 could be
detachably connected to a filter by a number of conventional
methods including a threading structure. It should also be
appreciated that the base 26 could be of a number of geometries to
fit the geometries of a desired filter or that an interface could
be used to couple a filter base 26 of one geometry to a filter 28
of another geometry.
[0020] While embodiments have been described in detail, it should
be appreciated that various modifications and/or variations may be
made without departing from the scope or spirit of the invention.
In this regard it is important to note that practicing the
invention is not limited to the applications described herein. Many
other applications and/or alterations may be utilized provided that
such other applications and/or alterations do not depart from the
intended purpose of the invention. Also, features illustrated or
described as part of one embodiment may be used in another
embodiment to provide yet another embodiment such that the features
are not limited to the embodiments described herein. Thus, it is
intended that the invention cover all such embodiments and
variations. Nothing in this disclosure is intended to limit the
scope of the invention in any way.
