FASTENER RETAINING DEVICE

摘要

An integrally moulded object body is disclosed for retaining fasteners in a pre-attachment position and deforming to accommodate attachment tolerances. The object body has a fastener retaining portion that has an aperture defined therein that has a fastener-engaging edge that grips the shaft of the fastener in the pre-attachment position. The fastener retaining is deformable to allow the fastener to move laterally and be attached off-center from the pre-attachment position to accommodate attachment tolerances. The fastener retaining portion can have areas of weakness to allow deformation. These areas of weakness can comprise areas of reduced thickness or radial extensions that extend towards the perimeter of the fastener retaining portion. The object body also has a clearance portion that defines a mounting face that the fastener does not extend past in the pre-attachment position. The object body can further comprise a compression portion that engages with the shoulder of the fastener and is compressed between the shoulder the object that the object body is attached onto in the attachment position. The compression portion can also have a bushing that provides increased torque retention by engaging with the fastener shoulder and the object that the object body is attached onto.

主权项

1. An object to be fastened by a fastener, the fastener having a shaft with a longitudinal axis and having a shoulder extending outwardly from the longitudinal axis beyond the shaft, the object comprising:
an integrally moulded object body having a fastener retaining portion and a fastener clearance portion, the fastener retaining portion defining an aperture with an axis for engaging the fastener shaft, the aperture having at least one fastener-engaging edge for retaining the fastener within the aperture in a pre-attachment position, the fastener retaining portion being deformable for facilitating movement of the longitudinal axis of the fastener away from the axis and into the fastener retaining portion, and the fastener clearance portion being spaced about the fastener retaining portion and extending longitudinally from the fastener retaining portion to provide a mounting face for the pre-attachment position.
