Abstract:
An example hinge includes a hinge pin extending along an axis and a first knuckle for receiving the hinge pin. The first knuckle is rotatable about the axis. A second knuckle for receiving the hinge pin and is rotatable about the axis. At least one bearing limits relative rotation between the first hinge knuckle and the hinge pin. The example hinge assembly may include a tolerance ring between the hinge pin and the first knuckle to urge the bearing away from the axis. An example method of producing a hinge includes the steps of permitting a first hinge plate to move relative a hinge pin and limiting movement of a second hinge plate relative a hinge pin. The method biases a bearing adjacent the hinge pin to limit movement of the second hinge plate relative the hinge pin.
Abstract:
A two piece hinge with cooperating hinge knuckles to pivotably join the hinge pieces. One of the hinge members includes a center tubular knuckle and the other of the hinge members has a pair of tubular knuckles spaced apart to receive the center knuckle of the first hinge member. Tubular sleeves or bushings are positioned within each of the knuckles and a hinge pin is inserted through all the knuckles to correct the hinge members. Washers are inserted between the knuckles to prevent contact and end caps are secured to the hinge pin to maintain assembly of the hinge. The bushing inserts and washers are made of an anti-friction material to minimize wear on the hinge.
Abstract:
A sliding door suspension system and a sliding door assembly for supporting a heavy sliding door from a door frame includes a rail horizontally mounted to the door frame. The suspension system includes a roller assembly which rollingly engages the rail and supports the heavy door. The roller assembly includes an axle or shaft having a bearing surface. The axle has at least one threaded end for securing the roller assembly and for attaching the roller assembly to a door hanger from which the heavy door is suspended. The roller assembly further includes a roller with a concentric hollow bore for seating a bearing assembly or bushing through which the axle extends in supportive engagement with the bearing assembly. The rail has a convex arcuate upper roller guide surface. The roller has a concave arcuate roller guide engaging surface which conforms to and engages the upper surface of the rail. The roller assembly also includes a door height and alignment adjusting member which threadably engages the axle. In one embodiment, the door height adjusting member comprises an eccentric sleeve, whereas in an alternative embodiment, the door height adjusting member comprises an adjuster block.
Abstract:
A low friction, long life concealed bearing hinge has plastic bushings inserted in the abutting ends of adjacent hinge knuckles. A hinge pin through the bushings results in a radial bearing surface between the hinge pin and the hinge bushing. The smooth outside faces on adjacent axially abutting bushings provide a thrust bearing between adjacent knuckles. The plastic materials are selected to interact mutually and with the hinge pin in a favorable way to retard wear.
Abstract:
A fitting for a panel, for example of toughened and/or laminated glass, comprising first and second mounting holes. The fitting comprises first and second mounting portions arranged to be disposed within the first and second mounting holes respectively, and first and second eccentric bushes located over the first and second mounting portions respectively. Each eccentric bush defines an interior circle in contact with the exterior of its respective mounting portion, and an exterior circle in contact with the interior of its respective mounting hole. The centre of the interior circle of each eccentric bush is offset from the centre of the exterior circle of that eccentric bush, so that each eccentric bush can be rotated with respect to its respective mounting hole and mounting portion to change the position of the mounting portion within the mounting hole.
Abstract:
There is provided a hinge with torque setting function for connecting two objects by a hinge shaft adapted to be assembled with precision and to be tightened easily. In order to reduce the diameter of the curvature portion 42 of the holder 40 through the brake member 30 on the hinge shaft 20, there is attached by the screw the adjusting member 46 which can vertically move within the latch portions (vertical grooves) 42G of the curvature portion 42 individually from an angular movement of the curvature portion 42 when it is tightened. The screw 5 can be tightened by vertical movement thereof without being restrained by the angular movement of the curvature portion 42 and therefore, the tightening of the holder 40 can be carried out with high precision and effectiveness of operation.
Abstract:
The invention relates to a mounting element for fixing fittings, in particular strip parts (B), to a frame or a casement, said element comprising a fixing part (1, 201, 301, 401, 501, 601, 701) that can be attached to the frame or casement. The fixing part (1, 201, 301, 401, 501, 601, 701) is provided with a threaded extension, which can be rotated about its longitudinal axis (S) and is held in a fixed manner in the direction of said longitudinal axis (S).
Abstract:
Es wird ein Schiebeflügel für eine Tür beschrieben. Der Flügel weist einen Türschuh 2 auf, der aus einem oberen Teil 21 und einem unteren Teil 22 besteht, wobei der obere Teil 21 mit einem in einer Laufschiene geführten Rollenwagen verbunden ist und der untere Teil 22 mit den Scheiben des Flügels verbunden ist, indem er diese an der Oberkante umfaßt. Der obere Teil 21 ist mit dem unteren Teil 22 über eine Justiereinrichtung 5 verbunden, über die eine Justierung in vertikaler Richtung erfolgen kann. Die Teile 21 und 22 des Türschuhs sowie die Justiereinrichtung 5 sind über Blenden 2a, 2b abgedeckt. Die Blende übergreift dabei zusätzlich auch den oberen Randbereich der Scheiben. Mit der also im Türschuh und somit im Flügel 4 integrierten Justiereinrichtung ergeben sich optische Vorteile, da die Justiereinrichtung nach außen nicht sichtbar ist.
Abstract:
The present invention provides an insulating structure for preventing a heat bridge and a window system with the same. The insulating structure for preventing a heat bridge is provided between structural frames to prevent thermal conduction. The insulating structure for preventing a heat bridge comprises: a fixing part including a first fixing member and a second fixing member, which are installed to be spaced apart from each other, and connected to the structural frames; an insulating member installed between the first and second fixing members, and fixed by the fixing part; and a plurality of reinforcing members installed in the insulating member to penetrate therethrough in a longitudinal direction, and provided to connect the first and second fixing members with each other, improving the structural performance.
Abstract:
PURPOSE: A mechanical door closure is provided to reduce the manufacturing cost or maintenance cost by simplifying the structure as the mechanical structure, to keep the opened condition of a door, and to prevent the leak of flame or fire smoke by rapidly closing a door in a fire. CONSTITUTION: A mechanical door closure comprises a housing(100), a power transmission device(200), a door closing device(300), a door deceleration device(400), an elastic adjustment device, and a cover. The housing comprises a first interlocking arm and a second interlocking arm(A2) and is installed in the upper part of a doorframe of a building. The power transmission device is installed in the housing and makes the door closely contacted to the doorframe in a fire. The door closing device keeps the opened condition of a door and forcedly closes the door in an emergency like a fire. The door deceleration device is connected to the power transmission device, and reduces the closed speed of the door while moving straight. The elastic adjustment device is installed in the housing to control the closed speed of the door. The cover covers the housing.
