<p>An automobile decklid pop-up bumper (10) for assembly with an apertured workpiece, such as the framework of an automobile engine compartment having an aperture and a helical internal marginal portion defined around the aperture, includes a housing (12) with an enlarged end portion (20) for engaging the automobile bonnet and a shank portion (28) extending from the enlarged end portion for inspection through the aperture. The shank portion (28) has a helical thread (32) for threadingly engaging the helical marginal portion around the aperture. The housing (12) has an axial bore (46) with a portion (48) of reduced radial dimension within the enlarged end portion (20). The portion (48) of reduced radial dimension defines a shoulder (50). Disposed within the axial bore (46) is a plunger (14) having an elongate cylindrical portion (54) and a disk-like base (56), the elongate cylindrical portion (54) extending through the portion (48) of reduced radial dimension and the disk-like base (56) interfering with the shoulder (50) to prevent the plunger (14) from passing completely through the axial bore (46). Biasing means (42, 44) direct the elongate cylindrical portion (54) out through the enlarged end portion (20) of the housing (12), and enable the plunger (14) to raise the bonnet by a slight amount when the bonnet latch mechanism is released. <IMAGE></p> |
