A sound damping door system having a door frame, a compression seal, a door slab, a bottom seal, and a concealed hinge assembly. The door frame includes male and female components adapted to engage each other in a rough door opening between first and second wall faces; and at least one isolation gasket adapted to be disposed between the male and female components. The compression seal is mounted to the door frame. The door slab includes an outer skin; an arched constrainment sheet inside the outer skin; a damping fill material inside the outer skin; and an acoustic insert inside the outer skin. The bottom seal is mounted to a bottom surface of the door slab such that the bottom seal is permitted to move relative to the door slab.

A tubular housing, a motor part that is provided in the housing, and an end damper and a damper member, one of each is provided on opposing ends of the motor part in an axial direction of the motor part and absorbs vibration, wherein the motor part is supported in a floating state by the housing via the end damper and the damper member.

An automatic door operator operating on standard 120V/240V AC power utilizes a servomotor for operation, and thus no separate transformer is required for the operator. The servomotor incorporates programming to limit torque, and thus no slip clutch is required in order to allow manual operation of the door. Furthermore, because the servomotor has built-in control logic, no separate digital control logic is required. Because the position of the servomotor is continuously maintained, the relative position of the door with respect to a fully opened or fully closed position is always known, and no separate external signal is required in order to monitor the door position.

A spindle drive assembly for opening and/or closing a vehicle hatch is described. This comprises a spindle extending along a spindle drive axis and a spindle drive motor coupled to the spindle in terms of drive, the motor shaft of which is arranged substantially coaxially with respect to the spindle drive axis. The spindle drive motor is coupled to the spindle via a two-stage epicyclic gearing. Furthermore, a vehicle hatch with such a spindle drive assembly is presented. A method for installing an epicyclic gearing of such a spindle drive assembly is additionally specified.

A locking slider can be used for a door trim, which has a plate and is mounted on a center roller of a sliding door. The locking slider includes two opening/closing members that are positioned on the plate to face each other and fastened or unfastened as multiple protrusions thereof engage or disengage. Two coupling members are formed at both sides of the plate to face each other so as to allow the opening/closing members to be seated on a movement route of the sliding door. The coupling members are configured to apply force to the opening/closing members from outside to inside. A separating member is formed at one side of the plate so as to be positioned between the coupling members. The separating member is configured to apply force to the opening/closing members from inside to outside.

A spindle drive assembly for opening and/or closing a vehicle flap is described, having a spindle and a spindle drive motor coupled thereto by means of a two-stage epicyclic gearing. A ratio of a number of teeth of each planet gear of a first epicyclic gearing stage to a number of teeth of each planet gear of a second epicyclic gearing stage is selected such that, in operation, a first sound frequency that is emitted by the first epicyclic gearing stage differs by an integer multiple of a semitone from a second sound frequency that is emitted by the second epicyclic gearing stage. In addition, a vehicle flap with such a spindle drive assembly is presented.

A door system includes a controller for controlling the door system. A user computer system transmits information to the controller over a wireless connection to modify operating parameters for controlling the operation of the door system. During installation of the door system sensors may be utilized to determine if the door system has been installed properly. The sensors may be used to identify if the door system is mounted level and plum, and to review the movement, vibration, speed, acceleration, force, or the like of the sensors, and thus, the components to which the sensors are operatively coupled in order to make adjustments to the door assembly. Furthermore, the operating parameters of the installed door system, may be cloned and provided to other door systems in order to quickly clone and distribute the operating parameters of one or more door systems to one or more other door systems.

Disclosed is a silent, soft-close compact hinge comprising of a hinge cup pivotally connected to a hinge body via a hinge arm. A set of coil springs biases the hinge to a closed position. A damping mechanism is removably attached to the hinge cup and acted on by the hinge arm. A set of spring sleeves are fitted to the coil springs to insulate the movement of the coil springs on the hinge arm providing the closing bias. The hinge body is comprised of three separate plates adjustably connected to each other with cam screws. The position of the hinge body with respect to the hinge arm is adjustable in three directions without the need for removal or loosening of mounting hardware used to attach the hinge body to a furniture piece.

A sliding door structure includes a rotary part that can rotate with respect to a door, a pair of first rollers holding a first guide rail therebetween, a pair of second rollers holding a second guide rail therebetween, a first roller support part that rotatably supports the pair of first rollers and can rotate with respect to the rotary part, and a second roller support part that rotatably supports the pair of second rollers and can rotate with respect to the rotary part.

The spring-biased garage door roller is configured for use with a garage door. The garage door comprises the garage door, a plurality of tracks, a plurality of roller wheels, and a plurality of compression springs. The plurality of roller wheels and the plurality of compression springs combine to attach the garage door to the plurality of tracks. The plurality of tracks guide the motion of the plurality of roller wheels. There is a one to one correspondence between the plurality of roller wheels and the plurality of compression springs. Each individual compression spring generates a motive force that urges its associated individual roller wheel into a track selected from the plurality of tracks.
