Plastic component having breakaway feature
View Patent ↗A plastic component is attached to a mounting structure by a fastener that extends at least into a mounting hole in the plastic component. The mounting hole is located near an edge corner of a cantilevered mounting tab that forms part of the plastic component. The mounting tab comprises a generally flat plate that has a depending flange that extends around a rounded corner near which the mounting hole is located and a depending sleeve that is contiguous with the mounting hole. The mounting tab has a break away portion so that the plastic component can be removed for recycling easily. Three variations of the breakaway portion are disclosed.
1. A plastic component adapted for attachment to a mounting structure by a fastener that extends at least into a mounting hole in the plastic component,
the mounting hole being located near an edge of a cantilevered mounting tab that forms part of the plastic component,
the mounting tab comprising generally flat plate that has a depending flange at the edge near which the mounting hole is located,
the plate having a depending sleeve that is contiguous with the mounting hole and that is spaced radially from the depending flange and that is reinforced by at least one depending gusset that is attached to the depending sleeve and to the depending flange and wherein the slit defines a breakaway portion, which extends from the mounting hole and to an edge defined by side walls of the flange,
wherein the depending sleeve has a slit that extends through the gusset and the depending flange.
2. The plastic component as defined in claim 1 wherein the gusset is attached to a first side wall of the flange, wherein the depending sleeve is reinforced by a second gusset that attaches the depending sleeve to the depending flange, and wherein the depending sleeve has a second slit that extends through the depending sleeve, the second gusset and the depending flange.
3. The plastic component as defined in claim 1 wherein the depending sleeve is reinforced by a plurality of gussets, at least two of which attach the depending sleeve to the depending flange.
4. A plastic component adapted for attachment to a mounting structure by a fastener that extends at least into a mounting hole in the plastic component,
the mounting hole being located near an edge of a cantilevered mounting tab that forms part of the plastic component,
the mounting tab comprising generally flat plate that has a depending flange at the edge near which the mounting hole is located,
the plate having a depending sleeve that is contiguous with the mounting hole and that is reinforced by at least one depending gusset that is attached to the depending sleeve,
wherein the depending sleeve is reinforced by a plurality of gussets, at least two of which attach the depending sleeve to the depending flange,
wherein the generally flat plate has a plurality of arcuate slots that extend through the generally flat plate, the arcuate slots being located outwardly and concentric with the depending sleeve, and wherein the gussets have slits that extend through the gussets in a concentric arrangement with the arcuate slots, and wherein the slots and slits define an annular breakaway portion.
5. The plastic component as defined in claim 1 wherein the generally flat plate has a slot that extends through the generally flat plate between the depending flange and the slit of the depending sleeve.
6. A plastic component of one piece construction adapted for attachment to a mounting structure by a fastener that extends at least into a mounting hole in the plastic component,
the mounting hole being located near a rounded corner of a cantilevered mounting tab that forms part of the plastic component,
the mounting tab comprising generally flat plate that has a depending flange that extends around the rounded corner near which the mounting hole is located,
the plate having a depending sleeve that is contiguous with the mounting hole, that is radially spaced from the depending flange, and that is reinforced by a plurality of gussets, at least two of which attach the depending sleeve to the depending flange, and
the depending sleeve having two slits that extend through the depending sleeve, the at least two gussets respectively and the depending flange to define a corner breakaway portion of the plastic component.
7. The plastic component as defined in claim 6 wherein the slits do not extend through the generally flat plate so that the top of the mounting tab has a smooth, pleasing unslotted appearance.
8. The plastic component as defined in claim 7 wherein the plurality of depending gussets are arranged in cruciform.
