Abstract: Pulleys of a block and tackle window balance include hub steps that interact with other components to reduce the introduction of dirt and dust particles into areas vulnerable to wear. The hub steps of some of the pulleys are recesses formed about the axial bores of the pulleys that mate with protrusions on an axle and a washer. The hub steps of other pulleys are protrusions that abut a support plate and heads of rivets that act as axles. The hub steps allow inverse mounting of the window balance so that the balance can be mounted in a shoe channel for movement with a sash of the window, attached to the sash shoe, and the cord can be attached to the jamb or frame, thus increasing sash travel.
Abstract: A low-profile hinge for hingedly joining adjacent door sections of a sectional door. The low profile for the low-profile hinge is attained by using a relatively small diameter hinge pin fabricated from spring steel. The greater strength characteristic of spring steel compensates for the smaller diameter of the spring steel hinge pin to provide a hinge that has a lower profile while maintaining the necessary mechanical strength at a level equal to or greater than a conventional hinge. The spring steel hinge pin is fabricated to be incrementally shorter than the pin tube and the ends of the pin tube are crimped to retain the spring steel hinge pin in the pin tube.

Abstract: The present invention relates to a safety hinge mechanism for foldable play yard and that is used to pivotally connect a first frame rod and a second frame rod thereof. The connecting bracket can be selectively rotated along the longitudinal axis of the frame rod into a locking position, or a neutralized position. A locking device is provided and disposed onto any one of the first and second frame rods. The locking device can be moved along the longitudinal direction into a locked position, or a released position. Wherein in the locked position, the locking device is engaged with the connecting bracket and the connecting bracket is prevented from any rotational movement thereof. As a result, the first and second frame rods are allowed to fully extend while they are not allowed to fold together. However, when the locking device and the connecting bracket are disengaged, the connecting bracket is rotated to a neutralized position and the first and second frame rods can be folded in a side-by-side manner.

Abstract: A through-wall bushing defines a protected passage through a wall or similar structure, and includes a first member having an axially extending threaded portion. A second ring member is threaded onto the first member and clamps the wall structure between opposing flanges of the first member and second ring member. At least one friction inducing locking mechanism is configured on at least one of the threaded surfaces of either the first or second member, or both members. This friction inducing locking mechanism has a configuration that increases the degree of torque required to tighten and loosen the respective members upon the threads engaging the locking mechanism. The locking mechanism has a shape so that, once engaged with opposite threads, the torque required to loosen the members is greater than the torque required to further tighten the members.
