Abstract:
A mounting system for a closure which enables the closure to be opened from at least two sides. The closure includes handles mounted on the two sides and is mounted to a frame which the closure closes with the at least two sides. The closure only be opened from one of the sides at a time. The mounting system includes a locking and releasing mechanism on each of the sides, at least one hinge attached to each of the respective sides, a control bar attached to each hinge, the bar substantially locked into a respective control system, and a control circuit comprising a sensor and a relay, associated with each of the handles, whereby if a person opens the closure from one side, the sensor on that side activates the corresponding relay to operate the control system on that side of the closure and the hinge on that side is retracted.
Abstract:
The power-operated door opening and closing system (10) of the present invention is of the kind adapted to be attached to the ceiling and comprises: an electric motor, an electric motor control unit, an electric push-button (P) actuating switch to control the motor operation, a string (30) or the like, and a mechanism adapted to convert the pulling of the string into a pressure upon the push-button switch or a pull of the pull-type switch.
Abstract:
A fast disassembling joint structure includes a base part and a removable part. One end of the removable part is secured to a desired structure; the other end is a connection arm. The housing has a raceway and a first semi-circular concavity. The movable clamp has an insertion section to engage a recess of the connection arm. The insertion section has a second semi-circular concavity to fit with the first semi-circular concavity so as to pivotally connect with the connection arm. A spring is adapted to provide a push force for the movable clamp. A top cover, secured on the housing, is employed to house the spring and movable clamp inside. A handle of the movable clamp extends out of an opening of the cover so that users can manually control the handle to disassemble the removable part.
Abstract:
A handle that is extendable and retractable to minimize interference with window decorations and having a feature, which allows removal and attachment of the handle from the crank of the window operator without the use of tools. The handle is removable from the window operator though the use of either a clip lock feature or a spring lock clip both of which can be top down assembled with the minimum of effort and complexity.
Abstract:
A foot operated door opener is formed as a triangular frame. The frame has an angular apex joint opposite the longer leg. The apex has an axle therethrough which is rotatably connected to a wall adjacent a sliding door. Pressure on the end of one leg of the frame causes rotation of the frame about the axle. The rotation causes another end of the frame to engage the sliding door and move it laterally to partially open the door.
Abstract:
A sliding door mechanism controls a door 10 in the form of a series of horizontal slats articulated to the slats above and below to move from a closed position in a vertical plane, along between tracks 14, until open. The door is moved by cables winding on or off a cable drum 12 driven through a drive belt 16 by an electric motor 18. The motor is on a carriage mounted at 30 to allow the drive belt to be slackened to remove drive from the drum 12. Control circuits 20 for the apparatus are described.
Abstract:
A rolling support assembly having a carrier with a housing configured for lateral reception within a corresponding cavity in a sliding door for frictional reception therein in a manner precluding longitudinal movement out of the cavity. The carrier mounts and provides for vertical adjustment of a depending wheel set offset to underlie the center of weight of the door and engage a pair of wheel rails provided on an underlying track including rail protecting overlying flanges and/or members.
Abstract:
A foot-operated, window-raising device for a window having a sliding sash, with the window being positioned a predetermined distance from a support surface. The foot-operated, window-raising device includes at least one pulley mounted to a frame member adjacent to the window and a moveable platform. A cord is threaded through the pulley and a first end is attached to the sliding sash. The cord is secured to the platform such that movement of the platform in a first direction causes the cord to open the sliding sash. The cord has a predetermined length which positions the platform between the window and the support surface at a height which is accessible by a user's foot. By stepping on the moveable platform, the platform moves in a first direction causing the cord to open the sliding sash.
Abstract:
An overhead door assembly designed particularly for use with vehicles such as railroad cars is disclosed. The door assembly is made up of an overhead door, vertical guide members for guiding the overhead door in the vertical direction and horizontal guide members for guiding the door in the horizontal direction. A motor is provided for driving the door between an open and a closed position. According to the invention, the door is first guided to a position directly in front of the door opening, but slightly spaced therefrom. The door is then moved horizontally in a plugging movement so as to securely close off the door opening.
Abstract:
A device (16b) for tilting windows, doors, ventilation hatches, or similar closures open, with a motorized transmission-activating mechanism (12b) and a transmission (14b) comprising two back-to-back chains that curve in opposite directions.
