Abstract: A locking nut includes a nut top, a nut middle, and a slip section. The nut top includes an integrally-formed bushing. The nut middle includes a threaded central bore suitable for threaded engagement on a threaded installation bolt, as well as a plurality of ratchet gears on an outer surface where each gear has a respective first slip surface and a first drive surface. The slip section includes a plurality of cantilevered posts having a respective free end, wherein on each post are formed a respective second slip surface and a second drive surface. When the slip section is rotated in a tightening direction, the slip section and the nut middle rotate together until a torque threshold is reached, where the second slip surfaces override the first slip surfaces to limit the applied torque. The locking nut includes structure to produce sound when the torque threshold has been reached.

Abstract: A toilet seat hinge includes a lock feature to releasably attach the hinge to a bolt head fastened to a toilet bowl. The hinge includes a hinge base, a key plate, and a grip. The hinge base includes a mounting structure to which a toilet seat can be pivotally mounted, as well as an aperture in a bottom surface thereof through which the bolt head can pass. The key plate includes a keyway having a large end that can be aligned with the aperture for insertion of the bolt head and can be slid into a locking position where the small end is aligned with the aperture to retain the bolt head within the hinge base. The user-movable grip includes a guide which travels in an L-shaped slot to restrain movement of the grip to an L-shape (two-movement) for moving the keyway into and out of locking position.

Abstract: A toilet seat hinge assembly that includes: a hinge configured for attachment to a toilet seat, a fastener including an expandable head; and a cap formed integrally with the hinge. The cap includes an engaging element extending from the first surface of the cap. The engaging element is configured to engage and expand the head of the fastener in order to releasably connect the toilet seat hinge assembly to a toilet bowl when the cap is in a first position relative to the base portion. A toilet seat assembly including the toilet seat hinge assembly.

Abstract: A co injection manifold assembly for injecting two different materials into a common mold cavity includes a housing that defines a first passage, a second passage and an outlet. The first and second passages communicate with a bore having a valve member for controlling flow of the material through the outlet. A first temperature control element in thermal contact with the first passage and a second temperature control element are in thermal contact with the second passage. Each of the first and second temperature control elements are separately controllable to provide separate temperatures for each of the first and second passages. Separate temperatures in each of the first and second passages provide for the use of materials having dissimilar molten temperatures.

Abstract: A toilet seat assembly is provided. The toilet seat assembly has a toilet seat ring and a toilet seat cover having cores of cellulosic materials such as wood derivatives or other natural cellulosic materials. The toilet seat ring and cover are encapsulated by a polymeric material bonded thereto, preferably polypropylene plastic. The plastic overlay has integrally formed hinge ears to allow the toilet seat ring to be pivotally connected with the toilet seat bowl.
