A method of manufacturing a door hinge, which can improve productivity by applying both metal injection molding and additive manufacturing is disclosed. The method includes: preparing a first mixture of a first metal powder and a first binder, and a second mixture of a second metal powder and a second binder; molding the first mixture into a first body including a first connection member having a first pinhole; molding the first mixture into a second body including a second connection member having a second pinhole to communicate with the first pinhole; arranging the first body and the second body to align the first pinhole and the second pinhole along an axis to form a cavity; forming a pin member with the second mixture in the cavity by adding up droplets of the second mixture in the cavity; and sintering the first body, the second body, and the pin member.

A roller including: a main body portion configured to include an outer ring and a rotatable inner ring on an inner circumferential side of the outer ring; and a covering portion disposed on an outer circumferential surface of the outer ring, the covering portion being made of a synthetic resin in which reinforced fibers are dispersed, wherein the covering portion includes a region in which arrangement directions of the reinforced fibers are aligned.

A hinged mobile computing device includes a first housing part with a first display and a second housing part with a second display. The first and second housing parts are coupled by a hinge assembly that includes a spring-loaded opening mechanism configured to bias with a biasing torque the first housing part and second housing part to rotate away from each other when the first and second displays are in a closed face-to-face orientation. An electro-magnetic closure system is configured to retain the first and second displays in the closed face-to-face orientation against the biasing torque of the spring-loaded opening mechanism, and release of the electro-magnetic closure system permits the first housing part to rotationally separate from the second housing part to a predetermined angular orientation due to the biasing force of the spring-loaded opening mechanism.

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.

A door hinge for an automobile includes a first bracket fixed to a body, a second bracket fixed to a door, and a hinge pin, the first bracket including a base plate portion having a bolt hole, a pair of arm plate portions standing up from upper and lower edges of one end part, on the door side, of the base plate portion and supporting the hinge pin, and a pair of rib portions extending from the arm plate portion and standing up from the upper and lower edges of the base plate portion so as to oppose each other with the bolt hole interposed therebetween, wherein opposite end parts, perpendicular to the extending direction of the rib portion, of the base plate portion are open, and the rib portion is formed so as to have a thickness larger than a thickness of the arm plate portion.

A method for producing a carrier element for a window lifting device in which adjustment of a glass is performed by means of a traction means, the carrier element being displaceable along a guide rail of the window lifting device and being connected to the traction means, is provided. The completed carrier element has at least two interconnected bodies which are produced from dissimilar materials having dissimilar melting points, and the carrier element having the at least two bodies is produced by a multicomponent injection-molding method. In the production of the carrier element by the multicomponent injection-molding method a body from a material melting at a lower temperature is molded before a body from a material melting at a higher temperature, and the body from the material melting at a higher temperature is molded to the body from the material melting at a lower temperature.

A hinged mobile computing device includes a first housing part and a second housing part coupled by a hinge assembly having a harness, a harness cover, a first hinge body, and a second hinge body. The harness is configured to accommodate flexible printed circuitry and a cable that extend from the first housing part to the second housing part via the hinge assembly. The hinge bodies include respective friction bands, each friction band being configured to engage a respective shaft formed on the harness and having a gear configured to mesh with a respective cog arranged within the harness cover to coordinate a timing of the rotation of the first and second housing parts between face-to-face and back-to-back orientations. The hinge assembly further includes a spring-loaded opening mechanism.

A method for assembling sub-assemblies to a receiving component in an assembly plant involves providing at least one assembly station, one or more sub-stations proximal to the assembly station, and at least one assembly device, the receiving component temporarily stopping in the assembly station, picking at least two sub-assemblies from the one or more sub-stations, and keeping the receiving component in a stationary status at least during assembling, by the at least one assembly device, the two sub-assemblies with the receiving component. In the stationary status, the receiving component remains in a same assembly status and/or in a same position and/or does not undergo other operations until the receiving component receives the at least two sub-assemblies. An assembly plant and an assembly line including the assembly plant are provided.

A method for assembling multicomponent items involves providing a first sub-assembly and a second sub-assembly, respectively picking, by a first manipulator arm and a second manipulator arm, the first and second sub-assemblies and bringing the first and second sub-assemblies to a mutual assembly position, assembling, by the first and second manipulator arms, the first and second sub-assemblies to form a joint assembly, sending a synchronous translation signal to the first and second manipulator arms, actuating a synchronous translation of the first and second manipulator arms and bringing the joint assembly to a receiving seat provided in a receiving component. An assembly station and an assembly line including the assembly station are provided.

A method for assembling two sub-assemblies involves providing a first sub-assembly and a second sub-assembly, by a first manipulator arm and a second manipulator arm, picking the first sub-assembly and the second sub-assembly, keeping the first and second sub-assemblies suspended, bringing the first and second sub-assemblies to a mutual assembly position and assembling the first and second sub-assemblies in a suspended-in-air position to form a joint assembly, avoiding all contact with any support other than the first and second manipulator arms. A method for assembling multicomponent items including the method for assembling the two sub-assemblies is provided. An assembly station and an assembly line including the assembly station are also provided.
