Abstract:
An image forming apparatus including a hinge assembly to mutually hinge-connect a main body and a cover unit of the image forming apparatus and the hinge assembly is provided. The image forming apparatus includes a main body, a cover unit configured to be disposed on an upper side of the main body to press a manuscript, and at least one hinge assembly configured to connect the cover unit to the main body, wherein the hinge assembly includes a first body detachably mounted on the main body, a second body of which a part is fastened to the cover unit and another part is hinge-connected with the first body, a pressing unit accommodated in the first body to press the second body upward, and a pressing force adjuster configured to adjust a hinge force between the first body and the second body.
Abstract:
A hinge device for rotatably moving a closing element includes a fixed element anchorable to a stationary support structure coupled to a movable element anchorable to the closing element for rotating around a first longitudinal axis between an open position and a closed position. The device further includes at least one slider movable along a second axis between a compressed and an extended position. One between the movable element and the fixed element includes at least one operating chamber defining the second axis so as to slidably house the slider, the other element including a pivot defining the first axis. The pivot and the slider are reciprocally coupled so that to the rotation of the movable element around the first axis corresponds the sliding of the slider along the second axis and vice versa.
Abstract:
A sliding door drive assembly is provided for a vehicle. The assembly includes at least one grooveless drum. The drum has a cable wrap surface and is rotatable to wind cable thereon and unwind cable therefrom. A guide is positioned to be aligned generally with a first axial edge of the cable wrap surface. As cable is wrapped on the drum, the angle of the cable (due to the position of the guide) biases the cable towards the first axial edge, so that successive wraps of cable are snuggly positioned adjacent prior wraps. In another aspect, a cable drum includes a ramp at a second axial edge of the cable wrap surface, which guides the cable radially outwardly to start a second layer of wraps of cable on the first layer of wraps. In another aspect, an absolute position sensor is provided for a powered sliding door.
Abstract:
A power boost assembly is disclosed that can be used with a door actuator, such as a door closer. The power boost assembly is structured to store an energy during a first movement of a door and release the stored energy during a second movement of the door. In one form the power boost assembly can be structured as a module that can be added to an existing door and door closer installation. In one form the power boost assembly is used to increase a closing force imparted to a door to ensure a latching event.
Abstract:
A hanger assembly for an architectural door or panel utilizes a head track connected to an overhead structural member with two concave tracks for receiving the convex wheel bearings which are attached to a hanger extending downwardly from the wheel bearings. The bottom of the hanger has a head which is inserted into a housing by way of an open groove. The housing is mounted to the frame of the door or panel. Rubber neoprene spacers are mounted between the head and the housing to adjust the vertical height of the door or panel relative to the head track and structural member. Additional wheel bearings may be added to the hanger as is necessary.
Abstract:
A sliding door roller system comprising a wheel housing, two roller wheels rotatably coupled to the wheel housing, an upper base, a second housing configured to be secured to a door and a ratchet mechanism coupled to the first housing and second housing, discretely stepping the second housing away from the first housing in a plurality of positions.
Abstract:
Door construction includes a door panel and at the top and at the bottom each time a self-closing pivot hinge. Each of the pivot hinges includes a spring which extends along the rotation axle and which provides a self-closing function to the pivot hinge. Each of the pivot hinges includes a first cam element and a second cam element which are pushed onto each other by the spring and push the door panel towards the closed position under the influence of the spring pressure. The first cam element includes at least one protrusion which upon rotation runs along a running surface with inclined parts of the second cam element. The second cam element is movably mounted in longitudinal direction of the pivot axle by means of a pen which is accommodated in a slotted hole of the second cam element. The slotted hole extends at least partly between the inclined parts of the running surface.
Abstract:
An adjustable torque hinge includes a set hinge, a torque providing unit and a torque adjusting unit. The set hinge unit couples a first and second wing plate with a pivot pin. The first and second wing plates forms a pin joint with a first sleeve and second sleeve. The torque providing unit includes a torque spring to provide turn back recovery. A torque adjusting unit has a torque adjustment member. The first sleeve includes a first cam, and the torque adjustment member includes a second cam which couples with the first cam to drive the torque adjustment member to the torque spring. Conversion between the first and second sleeves enables the bearing hinge to be used in both directions, accumulating force both in normal and reverse directions to adjust the torque force for opening and closing operations.
Abstract:
A constructive arrangement in elastomeric spring for closing doors which comprises a hollow tube having one end provided with a base and the inner area the provision of an elastomeric spring disposed juxtaposed to said base having a tracking member positioned on the elastomeric spring which receives the tracking member on the opposite face whose free end presents edge provided with female fitting which allows the positioning of a cam with male fitting pressed by a pin fixed to the tube through a bushing and having inner cap with fixing holes and protective cap.
Abstract:
A transversely movable hinge is mounted between a base and a cover of a folding device and has a moving assembly. The moving assembly is connected to an expansion device via a linking rod. Therefore, when the folding device is opened, the expansion device is driven to extend and is convenient for users. When the folding device is closed, the expansion device is driven to retract for saving space.
