Abstract

A connection includes a first component, second component and a cord member. The first component has an opening with an inner surface and a first annular groove disposed about the inner surface. The second component has a top end configured to fit in the opening. The top end has an outer surface with a second annular groove disposed about the outer surface. The first annular groove and the second annular groove are configured to form a channel in response to being disposed in cooperative alignment. The cord member is configured to be removably inserted into the channel to secure the first component to the second component. The cord member includes a tapered portion disposed at a distal end of the cord member and is configured to provide a mechanical advantage to urge the first annular groove and the second annular groove into cooperative alignment in response to being inserted therein.

First claim

We claim:

1. A connection comprising:
a first component having an opening with an inner surface and a first annular groove disposed about the inner surface;
a second component having a top end configured to fit in the opening, the top end having an outer surface with a second annular groove disposed about the outer surface, wherein the first annular groove and the second annular groove are configured to form a channel in response to being disposed in cooperative alignment; and
a cord member configured to be removably inserted into the channel to secure the first component to the second component, the cord member including a tapered portion disposed at a distal end of the cord member and configured to provide a mechanical advantage to urge the first annular groove and the second annular groove into cooperative alignment in response to being inserted therein, the cord member further including a tapered cutout portion disposed near a proximal end, the tapered cutout portion corresponding to the tapered portion and configured to receive the tapered portion.

2. The connection according to claim 1 , further comprising:
an access passage disposed through a side wall of the first component and in alignment with the first annular groove.

3. The connection according to claim 1 , further comprising:
a groove tapered portion corresponding to the tapered portion to receive the tapered portion.

4. The connection according to claim 3 , further comprising:
an indexing device to orient the first component and the second component.

5. The connection according to claim 1 , further comprising:
a grasping portion disposed at a proximal end of the cord member.

6. The connection according to claim 1 , further comprising:
a gripping surface disposed in the second annular groove and configured to grip the cord member, wherein rotation of the second component in a first direction relative to the first component is configured to urge the cord member into the channel.

7. A filter assembly comprising:
a base having an opening with an inner surface and a first annular groove disposed about the inner surface;
a filter housing having a top end configured to fit in the opening, the top end having an outer surface with a second annular groove disposed about the outer surface, wherein the first annular groove and the second annular groove are configured to form a channel in response to being disposed in cooperative alignment, wherein the channel includes a groove tapered portion;
an access passage extending from the channel to an outer surface of the base, the access passage being circumferentially spaced from the groove tapered portion; and
a cord member configured to be removably inserted into the channel to generate a connection between the base and filter housing, the connection being defined by the cord member disposed within the channel to maintain alignment of the first annular groove with the second annular groove, the cord member including a tapered portion disposed at a distal end of the cord member and configured to provide a mechanical advantage to urge the first annular groove and the second annular groove into cooperative alignment in response to being inserted therein, wherein the groove tapered portion is configured to receive the tapered portion of the cord member when the cord member is fully inserted into the channel.

8. The filter assembly according to claim 7 , wherein the the access passage is disposed through a side wall of the base and in alignment with the first annular groove.

9. The filter assembly according to claim 7 , further comprising:
An indexing device to orient the base and the filter housing.

10. The filter assembly according to claim 7 , further comprising:
a grasping portion disposed at a proximal end of the cord member.

11. The filter assembly according to claim 7 , further comprising:
a gripping surface disposed in the second annular groove and configured to grip the cord member, wherein rotation of the filter housing in a first direction relative to the base is configured to urge the cord member into the channel.

12. The filter assembly according to claim 7 , further comprising:
a filter element disposed within the filter housing.

13. The filter assembly according to claim 7 , further comprising:
a first gasket seat disposed about the inner surface of the base;
a second gasket seat disposed about the outer surface of the filter housing; and
a gasket configured to form a seal in response to the gasket being disposed between the first gasket seat and the second gasket seat, wherein the seal is formed in response to a predetermined amount of compressive force being applied to urge the base and the filter housing together.

14. The filter assembly according to claim 13 , wherein a slope of the tapered portion is configured to provide a predetermined amount mechanical advantage corresponding to the predetermined amount of compressive force to urge the base and the filter housing together.

15. The filter assembly according to claim 7 , wherein the cord member is beaded.

16. A cord member comprising:
a first end;
a second end; and
a body disposed between the first end and the second end, the body having a length, height, and width, the body including:
a tapered portion disposed along a portion of the length of the body and ending at the first end, the tapered portion being configured to taper down from the height of the body to a lesser height at the first end; and
a tapered cutout portion disposed near the second end, the tapered portion being configured to receive the tapered portion, wherein a combined height of the tapered portion and the tapered cutout portion is equal to the height of the body.

17. The connection according to claim 16 , further comprising:
a grasping portion disposed at a proximal end of the cord member.
