Snap fit fastener
View Patent ↗A snap fit fastener includes a base, a holder, and a plurality of snap fit arms. The holder extends from the base and includes a holder wall defining a fastener hole. The fastener hole is sized to receive a finger. The snap fit arms are cantilevered from the base. Each snap fit arm includes a beam and an overhang protruding from the beam in a direction away from the holder. Each overhang is configured to engage a panel to couple the snap fit fastener to the panel.
1. A snap fit fastener for fastening a panel, comprising:
a base defining a substantially planar base surface;
a holder extending from the base, the holder including a holder wall defining a fastener hole;
a plurality of snap fit arms cantilevered from the base, each snap fit arm including a cantilever beam and an overhang protruding from the cantilever beam away from the holder;
wherein each cantilever beam includes a first beam end portion and a second beam end portion opposite the first beam end portion, the second beam end portion is free, the first beam end portion is coupled to the base, and the overhang protrudes directly from the second beam end portion; and
wherein each overhang is configured to engage the panel to couple the snap fit fastener to the panel;
wherein the holder wall includes a first wall portion, a second wall portion, and a third wall portion, the third wall portion being arch-shaped and interconnecting the first and second wall portions; and
the first and second wall portions being connected to the base such that the first and second wall portions and each cantilever beam extend in a direction substantially perpendicular to the substantially planar base surface.
2. The snap fit fastener of claim 1 , wherein each cantilever beam extends along a beam axis, the beam axis extends perpendicular to the substantially planar base surface, the overhang includes a ramp obliquely angled relative to the beam axis and an abutment surface directly connected to the ramp, and the abutment surface is perpendicular to the beam axis.
3. The snap fit fastener of claim 1 , wherein the holder wall defines a first holder edge and a second holder edge opposite the first holder edge, the second holder edge is spaced apart from the first holder edge, and the snap fit fastener includes a first support wall coupled between the base and the first holder edge and a second support wall coupled between the base and the second holder edge.
4. The snap fit fastener of claim 3 , further comprising ribs coupled between the base and the first support wall, wherein the ribs are directly connected to the base, and the ribs are directly connected to the first support wall.
5. The snap fit fastener of claim 1 , wherein the first beam end portion of each cantilever beam is connected to the base at a location that is spaced apart from a location where the first wall portion is connected to the base and from a location where the second wall portion is connected to the base.
