Knock down pivot fastener

A pivot fastener useful in coupling a first part to a second part, comprising:

• a bearing post member, having an anchoring portion and a bearing portion, said bearing portion including a bearing surface and a first circumferential retaining flange;
• a first bushing member, having an outer surface with means for securing said first bushing member in fixed relationship to a first part, said first bushing member also having a mating face including a first axially-extending opening for receiving the anchor portion of said post member in a locking relationship preventing separation thereof or relative rotation therebetween;
• a second bushing member having an outer surface with means for securing said second bushing member in fixed relationship to a second part, said second bushing member also having a mating face including a second axially-extending opening, coextensive with said bearing post member, for receiving the bearing portion of said bearing post member therethrough, said second opening having a mating bearing surface with a reduced diameter portion for engaging said first retaining flange in a snap-fit relationship for preventing separation of said first and second bushing members when the bearing post member is received therein, while also permitting relative axial rotation therebetween;
• and
• means, including said bearing surface on said bearing portion coacting with said mating bearing surface on said second axially-extending opening in said second bushing member, for resisting normal rotation of said first bushing member relative to the second bushing member while also permitting relative axial rotation therebetween, wherein said normal rotation is about an axis perpendicular to the axis of said bearing post member.

A pivot fastener useful in coupling a first part with a first bore to a second part with a second bore, comprising;

• a first bushing member, said first bushing member having a first mating face portion and a first lead end portion, said first lead end portion having an expanded state and an unexpanded state, said first lead end portion sized for insertion into said first bore and having an axially extending first aperture with a knurled surface, said first mating face portion including a central bearing post section and a first circumferential ring section, said bearing post section including an axially extending bearing post member having a bearing end with a first circumferential retaining flange and an adjacent base portion with a knurled outer surface, said first mating face portion having a first sleeve detachably connecting said bearing post section to said first ring section, said first sleeve detaching permitting said bearing post section to advance through said first aperture and expanding said first lead end portion securing said first bushing member in fixed relationship in said first bore, the surface of said first aperture engaging with said base portion preventing separation of said bearing post section from said first ring section;
• and,
• a second bushing member, said second bushing member having a second mating face portion and a second lead end portion, said second lead end portion having an expanded state and an unexpanded state, said second lead end portion sized for insertion into said second bore and having an axially extending second aperture with a knurled surface, said second mating face portion including a central bearing post receiving section and a second circumferential ring section, said bearing post receiving section having a knurled outer surface, said bearing post receiving section having an axially-extending opening for receiving said bearing end of said bearing post member, said opening engaging said first retaining flange preventing separation of said first bushing member from said second bushing member once said bearing post member is inserted therein while also permitting said first bushing member to rotate axially relative to said second bushing member, said second mating face portion having a second sleeve detachably connecting said bearing post receiving section to said second ring section, said second sleeve detaching permitting said bearing post receiving section to advance through said second aperture expanding said second lead end portion and securing said second bushing member in said second bore, said second aperture engaging said bearing post receiving section preventing separation of said bearing post receiving section and said second ring section;
• and
• means, including said bearing end on said bearing post member coacting with said axially-extending opening in said second bushing member, for resisting normal rotation of said first bushing member relative to the second bushing member while also permitting relative axial rotation therebetween, wherein said normal rotation is about an axis perpendicular to the axis of said bearing post member.

A pivot fastener useful in coupling a first part to a second part, comprising:

• a first bushing member having an outer surface with means for securing said first bushing member in fixed relationship to a first part, said first bushing member also having a first mating face including an axially-extending first bearing post member with a bearing end;
• a second bushing member having a second mating face, an outer end surface and an outer circumferential surface with means for securing said second bushing member in fixed relationship to a second part, said second bushing member also having a first bore axially extending between said second mating face and said outer end surface, for receiving the bearing end of the first bearing post member therethrough, said first bore having a mating bearing surface permitting relative axial rotation therebetween;
• and
• means, including said first bearing post member coacting with said outer end surface of said second bushing member, for resisting separation of said first bushing member relative to the second bushing member while also permitting relative axial rotation therebetween, and wherein said means for resisting separation comprises:
• an axially-extending second bore in said bearing end of said bearing member;
• said outer end surface having a countersunck portion with a first bearing surface and a centrally-located opening axially aligned and contiguous with said first bore in the second bushing member;
• and
• a retaining pin having a head portion with a second bearing surface and a second post member with a knurled outer surface, said second post member projecting perpendicularly from said second bearing surface of said head portion, said second bearing surface being in bearing contact with said first bearing surface within said countersunck portion permitting axial rotation therebetween, said second post member extending axially through said opening and said first bore, the knurled outer surface of the post member being in press-fit engagement with said second bore in said first bearing post member.
