Blow molded assembly with an attachment fastener portion, and method thereof
View Patent ↗A blow molded assembly includes an attachment fastener portion integrated with a plastic component portion, and is formed by a blow molding process. The attachment fastener portion has a shaft and a base, where the base has at least one aperture and a bearing surface. The shaft extends from the bearing surface. The at least one aperture is configured to allow plastic for the plastic component portion to flow sufficiently through the base during the blow molding process such that the attachment fastener portion and the plastic component portion are integrated. The base of the attachment fastener portion may be substantially embedded within the plastic component portion. The shaft of the attachment fastener portion may be configured to receive a matable fastener such that the blow molded assembly may be attached to a structure. To accomplish this, the shaft may be threaded.
1. An assembly, comprising:
an attachment fastener portion and a plastic component portion, the attachment fastener portion integrated with the plastic component portion and having:
a base including a base body, the base body having a first surface and a second surface opposite the first surface, the base defining at least one aperture extending through the base body such that the at least one aperture extends from the first surface to the second surface; and
a shaft extending from the first surface;
wherein at least part of the plastic component portion extends through the at least one aperture.
2. The assembly of claim 1 , wherein the base defines a third surface extending from the second surface to the first surface along a first direction, and the at least one aperture extends through the base body along the first direction, the shaft extends from the first surface along the first direction, the first and second surfaces extends along a second direction, and the second direction is substantially perpendicular to the first direction.
3. The assembly of claim 2 , wherein the at least one aperture is a plurality of apertures disposed around the shaft.
4. The assembly of claim 1 wherein the base and the shaft are made of steel.
5. The assembly of claim 1 wherein the shaft is welded to the base.
6. The assembly of claim 1 wherein the shaft is configured to receive a matable fastener such that the assembly is securable to a structure.
7. The assembly of claim 6 wherein at least a portion of the shaft is threaded.
8. The assembly of claim 1 wherein the base of the attachment fastener portion is substantially embedded within the plastic component portion.
9. The assembly of claim 1 wherein the plastic component portion is made of acrylonitrile butadiene styrene (ABS).
