Abstract
A fastener includes an upper retaining portion, a body and a pin. The upper retaining portion has an aperture. The body has first and second side portions. The first and second side portions have first and second ends. The first ends of the first and second side portions are coupled to a surface of the upper retaining portion on opposite sides of the aperture and extending in a direction away from the surface of the upper retaining portion. The first and second side portions having a plurality of branch portions coupled to an outer surface of the respective first and second side portions. The pin has a top and an insertion portion. The insertion portion is adapted to be inserted through the aperture of the upper retaining portion, thereby expanding the body in outward directions.
Claims14
A fastener comprising:
- an upper retaining portion having an aperture;
- a body having first and second side portions, the first and second side portions having first and second ends, the first ends of the first and second side portions being coupled to a surface of the upper retaining portion on opposite sides of the aperture and extending in a direction away from the surface of the upper retaining portion, the first and second side portions having a plurality of branch portions coupled to an outer surface of the respective first and second side portions;
- and
- a pin having a top and an insertion portion, the insertion portion having a uniform cross section along its length and adapted to be inserted through the aperture of the upper retaining portion, thereby expanding the body in outward directions.
A fastener comprising:
- a pin having a shank, the shank having a uniform cross section along its length;
- and
- a base portion including an upper retaining portion defining an aperture, the base portion further including a plurality of arms extending in a direction substantially parallel to an axis passing through the aperture, the plurality of arms each including a plurality of radially extending ribs and defining a channel for receiving the shank of the pin, the channel being aligned with the aperture, the plurality of arms configured to outwardly expand upon introduction of the shank through the aperture and into the channel.
A fastener comprising:
- an upper retaining portion having an aperture;
- a body having first and second side portions, the first and second side portions having first and second ends, the first ends of the first and second side portions being coupled to a surface of the upper retaining portion on opposite sides of the aperture and extending in a direction away from the surface of the upper retaining portion, the first and second side portions having a plurality of branch portions coupled to an outer surface of the respective first and second side portions, the branch portions having a reduced thickness near the upper retaining portion;
- and
- a pin having a top and an insertion portion, the insertion portion being adapted to be inserted through the aperture of the upper retaining portion, thereby expanding the body in outward directions.
