Abstract

A fastener for coupling a first component to a mounting hole of a second component. The fastener includes a central body portion, a head portion, provided at the proximal end of the central body portion. The fastener has at least two resilient ribs, protruding radially outward from an outer surface of the central body portion. The fastener includes at least a first pair of diametrically opposed recessed surfaces, provided at the proximal end of the central body and extending axially between the head portion and a respective shoulder portion formed by each one of the first pair of recessed surfaces. The at least two resilient ribs extend along the outer surface of the central body portion in a direction along the central axis between the distal end and the proximal end, and axially past the respective shoulder portion.

First claim

The invention claimed is:

1. A fastener for coupling a first component to a mounting hole of a second component, the fastener comprising:
a central body portion, insertable through the mounting hole of the second component, having a distal end and a proximal end, and a central axis between said distal end and said proximal end;
a head portion, provided at said proximal end of said central body portion, configured to stoppingly engage with an upper surface of the second component, during use;
at least two resilient ribs, protruding radially outward from an outer surface of said central body portion;
at least a first pair of diametrically opposed recessed surfaces, each of which is recessed into the central body and provided at said proximal end of said central body, extending axially between said head portion and a respective shoulder portion formed by each one of said first pair of recessed surfaces towards said distal end, each one of said first pair of recessed surfaces is circumferentially spaced apart from a respective one of said at least two resilient ribs about said central axis and adapted to lockingly engage with the second component, during use, and
wherein said at least two resilient ribs extend along said outer surface of said central body portion in a direction along said central axis between said distal end and said proximal end, and axially past said respective shoulder portion.

2. A fastener according to claim 1 , wherein each one of said at least two resilient ribs is tapered towards said distal end of said central body portion.

3. A fastener according to claim 2 , wherein a proximal end portion of each one of said at least two resilient ribs is tapered towards said proximal end of said central body portion from a point longitudinally aligned with said shoulder portion of at least said first pair of recessed surfaces towards said proximal end of said central body portion.

4. A fastener according to claim 3 , wherein said proximal end portion of each one of said at least two resilient ribs is movable relative to said head portion.

5. A fastener according to claim 1 , comprising at least a second pair of diametrically opposed recessed surfaces, each one of said second pair of recessed surfaces is axially adjacent to and radially offset from a respective one of said first pair of recessed surfaces.

6. A fastener according to claim 5 , wherein a cross-sectional area of said central body portion defined by at least said first pair of recessed surfaces is greater than a cross-sectional area of said central body portion defined by at least said second pair of recessed surfaces.

7. A fastener according to claim 1 , wherein said central body portion has a substantially polygonal cross-section.

8. A fastener according to claim 1 , wherein said central body portion comprises at least two diametrically opposed longitudinal recesses, each one configured to accommodate a respective one of said at least two resilient ribs.

9. A fastener according to claim 8 , wherein each one of said at least two resilient ribs protrudes divergingly away from an inner surface of a respective one of said at least two diametrically opposed longitudinally recesses of said central body portion.

10. A fastener according to claim 1 , wherein said head portion comprises a resilient sealing member overmoulded onto a peripheral edge of said head portion and adapted to sealingly engage with the upper surface of the second component, during use.

11. A fastener for coupling a first component to a mounting hole of a second component, the fastener comprising:
a central body portion, insertable through the mounting hole of the second component, having a distal end and a proximal end, and a central axis between said distal end and said proximal end;
a head portion, provided at said proximal end of said central body portion, configured to stoppingly engage with an upper surface of the second component, during use;
at least two resilient ribs, protruding radially outward from an outer surface of said central body portion;
at least a first pair of diametrically opposed recessed surfaces, provided at said proximal end of said central body, extending axially between said head portion and a respective shoulder portion formed by each one of said first pair of recessed surfaces towards said distal end, each one of said first pair of recessed surfaces is circumferentially spaced apart from a respective one of said at least two resilient ribs about said central axis and adapted to lockingly engage with the second component, during use,
wherein said at least two resilient ribs extend along said outer surface of said central body portion in a direction along said central axis between said distal end and said proximal end, and axially past said respective shoulder portion;
wherein each one of said at least two resilient ribs includes an upper edge extending outwardly from said central body portion and facing said head portion, a proximal end portion extending from the upper edge and away from said head portion, and a distal end portion extending from the proximal end portion and away from said head portion, wherein the proximal end portion tapers, inwardly toward said central body portion, when moving from the distal end portion toward the upper edge.

12. A fastener for coupling a first component to a mounting hole of a second component, the fastener comprising:
a central body portion, insertable through the mounting hole of the second component, having a distal end and a proximal end, and a central axis between said distal end and said proximal end;
a head portion, provided at said proximal end of said central body portion, configured to stoppingly engage with an upper surface of the second component, during use;
at least two resilient ribs, protruding radially outward from an outer surface of said central body portion;
a first pair of diametrically opposed recessed surfaces, provided at said proximal end of said central body, extending axially between said head portion and a respective shoulder portion formed by each one of said first pair of recessed surfaces towards said distal end, each one of said first pair of recessed surfaces is circumferentially spaced apart from a respective one of said at least two resilient ribs about said central axis and adapted to lockingly engage with the second component, during use,
wherein said at least two resilient ribs extend along said outer surface of said central body portion in a direction along said central axis between said distal end and said proximal end, and axially past said respective shoulder portion; and
a second pair of diametrically opposed recessed surfaces, each recessed surface of said second pair of recessed surfaces is axially adjacent to, and radially offset from, a respective one of said recessed surfaces of said first pair of recessed surfaces.
