Abstract

Claims (32)

1. A push fitting joint packing arrangement, comprising:

a fitting having an outer wall, and an inner wall, wherein the inner wall defines a plurality of internal compartments and a pipe receiving cavity extending along a longitudinal axis of the fitting;

a monolithic retaining clip element maintained within at least one of the compartments, with the retaining clip element having a radially inner surface, a radially outer surface, an axially inner edge portion, an axially outer edge portion and an axial mid-segment, wherein the axially inner edge portion includes an axially extending platform and a radial back wall extending radially inwardly from the platform at least to at least one shoe extension, with the at least one shoe extension extending axially inwardly of the radial back wall and axially inwardly of the platform, and with the at least one shoe extension having a radially inner surface;

a pusher locking member slidingly engaged with the radially inner surface of the at least one shoe extension of the retaining clip element; and

a release pusher removably secured to the locking member,

wherein the at least one shoe extension and the platform are formed with a radial gap therebetween, and wherein the at least one shoe extension comprises a plurality of shoe extensions formed with gaps therebetween.

2. The arrangement of claim 1 , further including a fastening ring having a base and teeth, wherein the at least one shoe extension has an angled face that is not perpendicular or parallel to the longitudinal axis of the fitting, and wherein the angled face engages the fastening ring teeth.

3. The arrangement of claim 1 , wherein the axial mid-segment of the retaining clip member includes a radially inwardly extending blocker member having an axially outer wall.

4. The arrangement of claim 3 , wherein the axially outer wall of the blocker member extends at an angle of between thirty and sixty degrees from a floor of the axial mid-segment.

5. The arrangement of claim 1 , wherein the pusher locking member includes a radially inner surface, a radially outer surface, an axially inner segment, an axial mid-segment and an axially outer segment, wherein the axial mid-segment includes an angled ramp element extending radially outwardly from the radially outer surface.

6. The arrangement of claim 5 , wherein the ramp element has an axially inner face and an axially outer wall, and wherein the axially inner face extends from the radially outer surface at an angle of from approximately thirty degrees to approximately sixty degrees.

7. The arrangement of claim 5 , wherein the axially outer segment of the pusher locking member includes a wall segment having a radial slot formed therein.

8. The arrangement of claim 7 , wherein the wall segment forms a portion of the radially inner surface of the pusher locking member.

9. The arrangement of claim 7 , wherein the release pusher includes a neck portion having a ridge extending radially outwardly therefrom, and wherein the ridge is releasably engageable with the radial slot of the pusher locking member.

10. A method of enabling a fitting to receive a pipe through push connection, comprising:

providing a fitting having an outer wall, and an inner wall, wherein the inner wall defines a plurality of internal compartments and a pipe receiving cavity extending along a longitudinal axis of the fitting;

inserting a monolithic retaining clip element into the fitting cavity so as to be maintained within at least one of the compartments, wherein the retaining clip element has a radially inner surface, a radially outer surface, an axially inner edge portion, an axially outer edge portion and an axial mid-segment, wherein the axially inner edge portion includes an axially extending platform and a radial back wall extending radially inwardly from the platform at least to at least one shoe extension, with the at least one shoe extension extending axially inwardly of the radial back wall and axially inwardly of the platform, and with the at least one shoe extension having a radially inner surface;

inserting a pusher locking member into the fitting cavity so as to be slidingly engaged with the radially inner surface of the at least one shoe extension of the retaining clip element; and

releasably securing a release pusher to the locking member,

wherein the at least one shoe extension and the platform are formed with a radial gap therebetween, and wherein the at least one shoe extension comprises a plurality of shoe extensions formed with gaps therebetween.

11. The method of claim 10 further including the step of inserting at least one sealing ring and a fastening ring into the fitting cavity so as to be maintained within at least one of the compartments that is different from the compartment maintaining the retaining clip element.

12. The method of claim 11 further including the step of inserting a spacer gland member into the fitting cavity so as to reside axially between the at least one sealing ring and the fastening ring.

13. The method of claim 12 wherein at least one of the retaining clip element, the pusher locking member, the fastening ring and the spacer gland member is split.

14. The method of claim 12 wherein the retaining clip element and the spacer gland member are split.

15. A release pusher arrangement, comprising:

a pusher locking member having a radially inner surface, a radially outer surface, an axially inner segment, an axial mid-segment and an axially outer segment, wherein the axial mid-segment includes an angled ramp element extending radially outwardly from the radially outer surface, wherein the ramp element has an axially inner face and an axially outer wall;

a release pusher removably securable to the pusher locker member, wherein the release pusher has a neck portion with an inner radial wall and an outer radial wall, wherein the radially inner surface of the pusher locking member and the inner radial wall of the release pusher define a cavity of constant diameter extending along a longitudinal axis of the pusher locking member and release pusher when secured, and wherein the radially outer surface of the pusher locking member and the outer radial wall of the neck portion of the release pusher as it extends axially outwardly of the ramp element axially outer wall are co-planar; and

wherein the angled ramp element extends radially outwardly further than the outer radial wall of the release pusher neck portion.

16. The arrangement of claim 15 , wherein the axially inner face extends from the radially outer surface at an angle of from approximately thirty degrees to approximately sixty degrees.

17. The arrangement of claim 15 , wherein the axially outer segment of the pusher locking member includes a wall segment having a radial slot formed therein, wherein the wall segment is substantially parallel to the radially inner surface of the pusher locking member.

18. The arrangement of claim 17 , wherein the wall segment forms a portion of the radially inner surface of the pusher locking member.

19. The arrangement of claim 17 , wherein the release pusher neck portion has a ridge extending radially outwardly therefrom, and wherein the ridge is releasably engageable with the radial slot of the pusher locking member.
