A roller with a plastic injection tube to coat the steel shaft wherein the plastic coated shaft eliminates the metal-to-metal contact that creates the noise. Closing the gap between the metal roller shaft and hinge barrel will eliminate the metal-to-metal contact resulting in a very quiet, rolling garage door. Further disclosed is an improved roller wheel having a tire made of material selected from the group consisting of urethane and urethane (PER) on which the roller will roll within a garage door track to significantly reduce the noise of the roller as it rolls inside the garage door tracks as the garage door is raised and lowered. The improved wheel include two plastic wheel sections with a gap therebetween with the tire made of urethane (PER) molded between the two sections and also extending through openings within the two wheel sections to retain the two wheel sections together.

A door closer, comprising a door closer housing mounted to one of a door frame or a door surface and a linkage arm for pivoting the door between open and closed positions. The linkage arm has a first and second end, the first end mounted to the other of the door frame or the door surface. The door closer includes a rotatable connector between the linkage arm and the door closer housing, the linkage arm second end engaging with the rotatable connector. The connector has a rotatable body portion and head protrusion substantially secured in a female receptor to transmit rotation about a longitudinal axis of the connector. One or both of the head protrusion or female receptor has a curved profile and is further movable with respect to the head protrusion to permit limited rotational misalignment of the linkage arm on any axis perpendicular to the connector longitudinal axis.

In a invisible hidden door hinge (1), a first connecting body (2a) and a second connecting body (2b) are connected together by an articulation device (3) which allows the relative movement between a condition of opening and a closed condition in which the first (2a) and the second (2b) connecting body define a seat in which the articulation device (3). The articulation device (3) comprises at least one arm (32) with a first end (32a) on the first connecting body (2a) and a second end (32b), opposite to the second, on the second connecting body (2b). Said arm (32) is shaped from a respective single metal sheet in a single concave piece with concavity facing towards a reference plane parallel to the length direction (Z1, Z2) of the connection bodies (2a,2b) and passing through the ends (32a,32b) of the first arm (32).

In a invisible hidden door hinge (1), a first connecting body (2a) and a second connecting body (2b) are connected together by an articulation device (3) which allows the relative movement between a condition of opening and a closed condition in which the first (2a) and the second (2b) connecting body define a seat in which the articulation device (3) is enclosed. At least one of the connection bodies (2a, 2b) comprises a support structure (4a, 4b) in which, for a position adjustment, at least one movable body (5a, 5b) is housed which is shaped from a respective single metal sheet in a single concave piece having concavity defined by a bottom (52a, 52b) and by side walls (53a, 53b) that realize a continuous peripheral edge of the bottom (52a, 52b), joined to the bottom (52a, 52b) without interruption of the material of which said respective single metal sheet consists of and surrounding the bottom (52a, 52b) on at least three consecutive sides.

Disclosed is a device for automatically assembling a hinge, comprising a connecting piece module assembly device, an adjustment sheet module assembly device, a main body bracket module assembly device, and a finished hinge product assembly device, wherein the connecting piece module assembly device is used for assembling a connecting piece module; the adjustment sheet module assembly device is used for riveting an adjustment sheet module; the main body bracket module assembly device is used for assembling a main body bracket, a main body bracket bolt, and a screw into a main body bracket module; and the high finished product assembly device is used for assembling the connecting piece module, the adjustment sheet module, the main body bracket module, and other materials into a finished hinge product. The device for automatically assembling a hinge of the present invention is used for the automatic assembly of a hinge.

A slide member having a slide surface (14) coated with a lacquer comprising a resin(16). The lacquer is in turn at least partly coated with a lipophilic composition coating (18). The lipophilic composition coating provides a slide layer (19) on the slide member with low friction.

In a draw-in arrangement with a carrier element, which is movable back and forth from a force- and/or form-locking fixed park position to an end position and a carrier which can be coupled to the carrier element, the carrier is provided with a stop projection having a stop surface area and the carrier element has an engagement projection with a push surface area for contact with the stop projection. The stop projection is provided with a carrier-side surface layer. At least one of the surface areas is provided with an elastic surface layer to prevent contact noises. The invention also resides in a sliding door arrangement with such a draw-in arrangement to prevent contact noises.

An inverted constant force window balance system includes a carrier assembly and a mounting bracket. The carrier assembly includes a housing, a coil spring disposed within the housing, and a shoe assembly coupled to the housing. The shoe assembly is configured to receive a pivot bar from a window sash and extend at least one brake upon rotation of the pivot bar. The mounting bracket is releasably coupled to the housing opposite the shoe assembly and is coupled to the free end of the coil spring. At least a portion of the mounting bracket is configured to slideably move in relation to the free end of the coil spring between at least two positions. When at least a portion of the mounting bracket moves between the at least two positions, the mounting bracket disengages from the housing and releases the mounting bracket from the carrier assembly.

The disclosure makes an insulating component and a sensor bracket to be an integrally molded article, simplifies the manufacturing process and cuts down the cost. A sensor holder and a sensor bracket made of a resin are made to be an integrally molded article, wherein the sensor holder inside which a pair of electrodes are arranged, and the sensor bracket made of a resin which holds the sensor holder and is attached to a tailgate. During an operation of filling a molten resin to a cavity, a part of the sensor holder is melted by the molten resin, and thus integrating the sensor holder and the molten resin, therefore, the two components can be structurally and firmly integrated. Accordingly, a touch sensor unit which endures long-term use can be obtained.
