Abstract: The subject invention is a delay door closer that is to be used in conjunction with a dual door arrangement such as a screen door mounted in conjunction with an entry door of a house or other building. A catch mechanism is mounted on the door jamb with the catch mechanism functioning to lock and hold the screen door in an open position when the entry door is in the closed position. Upon opening of the entry door a sufficient amount to where the user is now able to enter the building, the catch mechanism is disengaged which will cause the screen door to be moved from its open position to a closed position.

Abstract: A caster is provided that includes a wheel rotatable about a wheel axis of rotation, a housing, a locking arm linked to the housing, and a locking bar linked to the housing. The housing includes a housing side wall and a housing detent formed in the housing side wall. The locking arm is movable between an unlocked position to permit the wheel to rotate about its wheel axis of rotation and a locked position to prevent or substantially restrict rotation of the wheel about its wheel axis of rotation. The locking arm is linked to the wheel so that movement of the locking arm between the locked and unlocked positions moves the wheel. The locking arm includes a locking arm side wall and a flared portion formed in the locking arm side wall and extending outwardly toward the housing side wall, the flared portion is engaged with the housing detent when the locking arm is in the locked position and disengaged from the housing detent when the locking arm is in the unlocked position.

Abstract: A blocking device for preventing a door closer from achieving a degree of rotation corresponding to a door hold-open position. A blocking device is provided which can be selectively protruded into a door closer housing to block the translation of a cam plate under influence of a rotating cam operatively connected to one of either the door or the door frame such that the 90.degree. or 105.degree. typical door hold open position cannot be achieved. The blocking device can be a rotatable limit bar which can be positioned to an interference or no-interference position, or it can be screw pins which can be threadingly inserted into the housing to block either the cam or other moving portions of the door closer such that the closer cannot achieve the door hold open position.

Abstract: A caster with a stem generally cylindrical over most of its external circumference, but provided with at least one flat face cut through the cylinder external circumference so as to provide the cylinder with a slight "D" shaped cross section. The stem is designed to seat in a corresponding "D" shaped bore hole of a mobile platform, the shapes cooperating to secure the stem against rotation. The stem is internally threaded, and can fit into either cylindrical or "D" shaped bore holes.

Abstract: A assemblage for mounting a caster wheel on a depending stationary post on a wheeled load carrier comprises a body element having a cylindrical chamber concentrically surrounding the support post. The body element has a bracket for mounting a caster wheel for rotation about a horizontal axis. A vertical stack of washers surround the support post and alternate ones of such washers are secured to the support post and rotatable within the cylindrical chamber while the remainder of such washers are co-rotatable with the body element about the axis of the support post. The cylindrical chamber is filled with a lubricating fluid to a sufficient depth to cover all abutting surfaces of said washers, thereby providing viscous fluid shearing resistance to shimmying movement of the caster wheel relative to the support post. To maintain the friction between the support post and body element independent of the amount of load, anti-friction thrust bearings are provided between the support post and the body element.

Abstract: A handle for a suitcase includes a base having two barrels disposed in the end portions for slidably receiving two tubes. A plate is secured to the bottom of the base and two slides are slidably engaged in the plate. The slides each has a latch for engaging with the tubes and each includes an inclined slot. A knob includes two inclined legs engaged with the inclined slots of the slides. The slides are moved toward each other or moved away from each other by the engagement of the inclined legs of the knob with the inclined slots of the slides.

Abstract: A caster assembly having rattle-free operation is presented. The caster comprises an inverted U-shaped horn member carrying an axle (i.e., a shoulder bolt). A wheel rotating on a spanner is supported between leg portions of the horn by the axle. A brake support and treadle lever are mounted on the axle and provide for locking the caster wheel. A spring tab is formed integrally in the treadle lever. The spring tab is spring biased inwardly to force the brake support and the treadle lever apart. The maintenance of a constant tension separating the brake support and the treadle lever results in rattlefree operation of the caster assembly of the present invention.

Abstract: A slide to be partially inserted under a floor contact portion of a heavy structure such that the structure can be easily slid a short distance. The slide is formed as a laminar assembly including a flat plate formed of an abrasion resistant lubric plastic material made of polyoxymethylene, homopolymer acetal, and a non-slip pad made of a synthetic plastic material. That portion of the plate not under the floor contact portion tends to bend upwardly so that the heavy structure slides easily over the floor while the pad keeps the heavy structure from sliding off the slide.

Abstract: A pivot hinge usable to support a swingable panel relative to a stationary support has a panel plate mounted on the panel and a support plate mounted on the support. The panel plate is provided with a panel pin projecting along an axis away from the panel and formed with a groove open axially away from the panel and elongated transversely of the axis. The support plate is provided with a support pin projecting along an axis parallel to the panel-pin axis toward the panel plate and engaged in the panel-plate groove and is formed with a groove open axially toward the panel, elongated transversely of the axes, and receiving the panel pin. Thus as the panel is swung relative to the support both pins move along the respective grooves.
