Abstract: A hinge and check assembly for checking the door of a motor vehicle when in the open position. The assembly provides a base having check profiles formed therein to establish predetermined check positions. The assembly also provides a strap that provides a spring biased contact surface for engaging the check profiles formed in the base. The strap is pivotally connected to the base through a pivot pin that defines a hinge axis, and the strap is allowed to rotate with the door of the vehicle about the hinge axis. Upon rotation of the strap, the contact surface follows the check profile and establishes a predetermined check position. The check profiles are perpendicular to the pivot pin, and the contact surfaces are perpendicular to the check profiles so that the check force applied to the pivot pin is in an axial direction. By having the check force applied axially to the pivot pin, deformation and wear to the pivot pin and its associated bushing does not occur.

Abstract: A mounting plate for detachably fixing a heavy duty, normally permanently attached, swivelling base plate caster roller unit to an object to be transported is cut from an extrusion shaped to form a flat bottom plate with raised parallel sides each including an overhanging flange such that parallel grooves are provided into which the caster's swiveling base plate can slide. Attachment of the mounting plate to the transportable object utilizes at least two mounting pins (screws, bolts or rivets), at least one of which protrudes from the mounting plate inside surface to form a stop to prevent the swivel plate from sliding all the way through. A spring loaded button, which becomes flush with the mounting plate when depressed, allows the caster swivel plate to enter the cavity provided by the parallel extruded grooves and the protruding mounting stop.

Abstract: A shower curtain rod has curved ends branching from the straight body. A curtain hung therefrom is caused to follow a curved contour of a bathtub below. Tracks are provided on the inner and outer sides of the curtain rod so that inner and outer curtains may be suspended therefrom. The inner curtain follows the bathtub contour, and the outer curtain extends to both of two parallel walls defining the shower stall. Curtain fasteners are slidably held within the tracks. The fasteners are insertable when turned ninety degrees from their normal, vertical orientation, then turned so that fastener hooks face downwardly. The fasteners are thus positively retained by the curtain rod, while allowing the curtains to be opened and closed independently from one another.
