  • Patent number: 5855039
    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.

  • Patent number: 5829097
    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 or 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.

  • Patent number: 5829096
    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.

  • Patent number: 5813090
    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.

  • Patent number: 5809612
    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.

  • Patent number: 5802668
    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.

  • Patent number: 5802669
    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.

  • Patent number: 5799370
    Abstract: An adjustable hinge has a first leaf and an adjustable leaf mounting assembly which includes a second leaf, a bracket, a cam and an adjusting screw. The second leaf is mounted on the bracket and has one end extending beyond the bracket and pivotally engaged with the first leaf. The cam is rotatably mounted on the bracket and cooperates with a cam follower surface on the second leaf. The adjusting screw has a shank threadably engaged in the second leaf intermediate its ends and has its free end abutting the bracket. In operation, the rotation of the adjusting screw pivots the one end of the second leaf relative to the bracket and the rotation of the cam moves the second leaf vertically relative to the bracket.
