Abstract
A bearing device is disclosed and can include a bushing. The bushing can include a hollow body that can have an internal diameter, IDHB, and proximal ends and distal ends opposite each other. The bushing can also include a first bushing flange extending radially outwardly from the proximal end of the body and an axial extension extending from the distal end of the hollow body. The axial extension is deformable so as to form a second bushing flange extending radially outwardly from the distal and of the hollow body. The axial extension can have an internal diameter, IDAE, ≦IDHB.
Claims17
A bearing device comprising:
- a bushing comprising:
- a hollow body having an internal diameter, IDHB, a proximal end and a distal end opposite each other;
- a first bushing flange extending radially outward from the proximal end of the body;
- and
- an axial extension extending from the distal end of the hollow body, the axial extension comprising a first portion that extends radially inward with respect to a longitudinal axis, and a second portion that extends longitudinally away from the first portion, wherein the first bushing flange has a thickness, TFF, and the axial extension has a thickness, TAF, and wherein TFF≦110% TAF,
- wherein:
- the axial extension is deformable so as to form a second bushing flange extending radially outwardly from the hollow body,
- the axial extension has an internal diameter, IDAE, that is less than IDHB, wherein the axial extension extends longitudinally away from the hollow body and a portion of the axial extension is bent inwards with respect to a longitudinal axis, and
- wherein (i) the axial extension comprises a concave sidewall that is bowed inward with respect to the longitudinal axis, and the axial extension comprises a first portion that extends radially inward with respect to the longitudinal axis to form a shoulder and a the second portion that extends longitudinally away from the first portion to form the concave sidewall, or (ii) the axial extension comprises a first portion that extends radially inward from the hollow body at a first bushing flange angle, A1, with respect to the longitudinal axis to form a ramp and a the second portion that extends radially outward from the first portion at a second bushing flange angle, A2, with respect the longitudinal axis to form a flange plate, and wherein A2≦60°.
6 more elements
A fastening device comprising:
- a bushing;
- and
- a rivet rotatably engaged with the bushing;
- wherein the bushing comprises:
- a hollow body having an internal diameter, IDHB, and proximal and distal ends opposite each other;
- a first bushing flange extending radially outward from the proximal end of the body;
- and
- an axial extension extending from the distal end of the hollow body, the axial extension comprising a first portion that extends radially inward with respect to a longitudinal axis, and a second portion that extends longitudinally away from the first portion, wherein the first bushing flange has a thickness, TFF, and the axial extension has a thickness, TAE, and wherein TFF≦110% TAE,
- wherein:
- the axial extension is deformable so as to form a second bushing flange extending radially outwardly from the hollow body,
- the axial extension has an internal diameter, IDAE, that is less than IDHB, wherein the axial extension extends longitudinally away from the hollow body and a portion of the axial extension is bent inwards with respect to a longitudinal axis, and
- wherein (i) the axial extension comprises a concave sidewall that is bowed inward with respect to the longitudinal axis, and the axial extension comprises a first portion that extends radially inward with respect to the longitudinal axis to form a shoulder and a the second portion that extends longitudinally away from the first portion to form the concave sidewall, or (ii) the axial extension comprises a first portion that extends radially inward from the hollow body at a first bushing flange angle, A1, with respect to the longitudinal axis to form a ramp and a the second portion that extends radially outward from the first portion at a second bushing flange angle, A2, with respect the longitudinal axis to form a flange plate, and wherein A2≦60°;
- wherein the rivet comprises:
- a body defining a proximal end and a distal end opposite the proximal end;
- a rivet flange extending radially outwardly from the proximal end of the body;
- and
- a deformable post extending from the distal end of the body, wherein the body is configured to fit into the hollow body such that the rivet flange is engaged with the first bushing flange of the bushing.
