Abstract: A dust cover for a ball joint includes a seal structure on a small-diameter opening section that prevents dust lip lift off during compression. The seal structure includes a seal lip and a dust lip that elastically abut against a seal surface located between a knuckle and a stud of the ball joint. The dust lip has an axial length in contact with a sloping part of the seal surface of 0.5 mm to 1.0 mm. Further, a tip of the dust lip is axially spaced apart from a tip of the seal lip by 0.5 mm to 1.2 mm.

Abstract: In one example, a bracket includes a swivel rotatably mounted on a hinge and a keyway separable from the hinge. The swivel includes a key, while the keyway includes a recess. The key and the recess are shaped to allow the swivel and the keyway to connect to each other in a plurality of positions.

Abstract: An extruded rail assembly including a first multi-channel extrusion having at least two tubular channels connected by a center rib, and having a joining end configured for joining at a predetermined angle to a joining end of a second multi-channel extrusion. The second multi-channel extrusion includes at least two tubular channels connected by a center rib, and having a joining end configured for joining at the predetermined angle to the joining end of first multi-channel extrusion. The joining ends of the first and second multi-channel extrusions are configured such that the center ribs complementarily engage as a joining surface.

Abstract: A locking dowel assembly for joining wooden objects without glue or screws includes a pair of cups. Each of the cups is inserted into a well in a respective pair of objects intended for joining together. A pair of inserts is provided and each of the inserts is positioned against each other such that the pair of inserts forms a cylinder. The cylinder is inserted into each of the cups for joining the objects together. A retainer is positioned between each of the inserts and the retainer has a plurality of teeth thereon. The teeth engage the cups when the insert is inserted into each of the cups thereby retaining the inserts in the cups.
