Abstract:
Disclosed is a low profile, adjustable, soft close hinge comprised of a hinge cup pivotally connected to a hinge body via a hinge arm and a hinge link in a four-bar linkage arrangement. A spring biases the hinge to a closed position. The hinge body is adjustably connected to an inner frame with an overlay adjustment screw and depth adjustment cam. The inner frame releasably connects the hinge body to a mounting plate. A stop bracket is adjustably and slidably connected to the hinge body by a helical cam. The adjustable position of the stop bracket relative to the hinge body determines the point at which the damping functionality of a damper begins during a hinge closing movement. A linkage sub-assembly pivotally connects the damper to the hinge link.

Abstract:
An accessory mounting bracket for securing door accessories to a door coordinator. The accessory mounting bracket has stepped portions that define a channel that is sized to receive a door coordinator. A recess is disposed below the channel and provides an offset for fasteners that mount the door coordinator to a door frame and may protrude from the door coordinator. A set of bores are used to attach the accessory mounting bracket to the door coordinator and a soffit of the door, while a second bores, which are threaded, allows for attachment of a door accessory to the accessory mounting bracket. The second bores are formed in the accessory mounting bracket so as to be spaced apart from the door coordinator.
Abstract:
A door closer assembly is configured to controllably close a door and to accommodate several door closer assembly installation configurations. The door closer assembly includes a housing that carries a pinion having a pinion shaft with a tri-lobe end portion. A closer arm having a tri-lobe opening is configured to receive the tri-lobe end portion of the pinion shaft in driving engagement. The tri-lobe end portion of the pinion shaft and the corresponding tri-lobe opening in the closer arm cooperate to limit the number of orientations that the closer arm may be connected to the pinion shaft.
Abstract:
A main support frame is formed from sections of a plastic extrusion and has opposite side portions with peripheral recesses receiving an inner sash unit and outer sash unit each having a frame formed from sections of a plastic extrusion and supporting an insulated glass unit. Hinges support the dual sash units for pivotal movement between open and closed positions, and gear connected telescopic link members connect the main frame to the sash frames for simultaneous movement. A lock system includes a handle on the inner sash unit for moving straps with studs on the sash frames through a connector mechanism mounted on the main frame for simultaneously locking and releasing both sash units and for releasing only the inner sash unit. A screen and/or mini-blind can be supported between the sash units, and the window system with dual sash units may be constructed in various forms.
Abstract:
A method of opening a mine door leaf installed in a mine passageway having a high pressure zone and a low pressure zone. The method includes the steps of operating a variable-throw crank mechanism in a first configuration having a first crank length to apply a first force to the mine door leaf to move it at a first speed, operating the variable-throw crank mechanism in a second configuration having a second crank length less than the first crank length to apply a second force greater than the first force to the mine door leaf to move it at a second speed slower than the first speed, and using a resistance pressure associated with the high and low pressure zones in the mine passageway to convert the variable-throw crank mechanism from the first configuration to the second configuration.

Abstract:
A mine door system comprising at least one mine door leaf hinged at one side thereof to a door frame defining an entry. The system includes an articulated door-moving mechanism that articulates between a first configuration in which the mechanism applies a relatively small door-moving force to the door leaf to move the door leaf at a first speed and a second configuration in which the mechanism applies a larger door-moving force to the door leaf to move the door leaf at a second speed less than the first speed. A related method is also disclosed.
Abstract:
An arm, forming a linkage arm, includes: a first linkage arm part; and a second linkage arm part. The first linkage arm part is arranged with one end at a driven shaft of a swing leaf operator so as to be fixed with respect to rotation relative to the driven shaft, so that the swing leaf operator can swivel the first linkage arm part around a first end of the first linkage arm part, as a center point of a rotational axis of the first linkage arm part, the first linkage arm part being configured, at a second end of the first linkage arm part, to be arranged at a first end of the second linkage arm part, so as to be fixed with respect to rotation relative to the second linkage arm part.
Abstract:
A hinge assembly is provided for pivotably attaching a door to a domestic appliance. The hinge assembly includes a hinge body having two mounting areas; a damper; a foot pivotably attached to the damper, the foot being configured to engage a foot receiving portion of the appliance body such that the hinge body and the door pivot relative to the appliance body; and a first mounting spacer attached to the hinge body at a first one of the mounting areas, the first mounting spacer being configured to attach to the door such that the hinge body is fixed relative to the door. Each of the two mounting areas is configured to receive a first fastener to attach the first mounting spacer to the hinge body, and each of the two mounting areas is configured to receive a second fastener to attach the door to the hinge body.
