This invention discloses a door opener, comprising a shell consisting of an upper cover plate (1) and a lower cover plate (2). The key is that a pushing device for pushing the door to rotate is provided in the shell. An end of a driving device, which has one or more springs, can drive, via a rotating member (3), the pushing device to rotate. A locking/releasing device, which cooperates with the driving device, is provided at the other end of the driving device. The structure of this invention is unique. It allows the door to be conveniently opened and will not cause any possible harm to the users.

The refrigerator includes a main body having an opening on a front side, an upper opening and a lower opening divided in the main body by a partition wall, an upper door to open and close the upper opening, a lower door to open and close the lower opening, and a hinge mechanism configured such that the door is rotatably coupled with respect to the main body, wherein the hinge mechanism includes a multiaxial hinge provided above and below each of the upper door and the lower door.

Embodiments for a kinematic control system for controlling the operation and movement of sliding panel for are disclosed.

A door opening and closing apparatus includes a setting unit configured to set at least a part of one of a first detection range and a second detection range as a start zone in which a first phase of a setting movement made by a detection target is to be detected, and to set a part of another one of the first detection range and the second detection range as a trigger zone in which a second phase of the setting movement is to be detected, based on first distances measured by a measurement unit. Upon determining that the detection target has made the setting movement including a movement between the start zone and the trigger, based on changes in the distances measured by the measurement unit, the control unit causes a driving unit to open or to close the door.

Hinge for the opening and the closing of hinged doors of furniture units, including a first fixed body designed to be housed in a seat of a horizontal plane of the structure of a furniture unit, such as a base or a top, and a second movable body designed to be housed in a seat of a door of the furniture unit, to actuate the door during opening and closing by way of a movement mechanism including at least one lever or connecting rod connecting a pin placed on the fixed part of the hinge and a pin placed on the movable part, wherein the closing force of the door is determined by a spring, the spring acting, with a tilting action, on an extension of the connecting rod beyond the hinge pin.

Friction hinge (21) for the pivotable connection of two components, comprising at least one first hinge sleeve (24) which is arranged in alignment with at least one further hinge sleeve (22), a shaft (11) which runs through the hinge sleeves (22, 24), and at least one friction spring for exerting a friction torque on the movable shaft (11), wherein at least two mutually aligned friction springs (10, 10′) are connected to the first hinge sleeve (24) via radial shoulders (16, 16′) and exert a friction torque on the shaft (11) mounted in the further hinge sleeve (22).

The invention relates to a fitting arrangement having a furniture connecting fitting, in particular a hatch holder, which can be used to attach a furniture hatch or a door can be to a cabinet body in a swiveling manner, wherein an interlock (200) and a bracket (300) are provided, which can be used to connect the furniture hatch in a form-fitting and/or form-locked manner to the furniture body in a closed position of a kinematic arrangement (30) of the furniture connecting fitting, wherein the kinematic arrangement (30) has levers and links, which can be used to move the furniture hatch or door from the closed position into an open position, wherein a spring element (38.2) is provided which, in the closed position of the kinematic arrangement (30), introduces a prestress into the kinematic arrangement (30) in the opening direction, and wherein the interlock (200) and the bracket (300) form a release mechanism, which can be used to release the connection between the interlock (200) and the bracket (300) in the closed position of the kinematic arrangement. Such a fitting arrangement can be used to effect a convenient opening of a door or hatch from the closed position.

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.

A sliding door assembly includes a door frame with a top trim member, a bottom sill, and side jambs connected between the top trim member and the bottom sill, and a primary sliding panel secured in the door frame. The top trim member includes a track configured to support a weight of the primary sliding panel and prevent the primary sliding panel from coming off the track. Other features include an interlock mechanism to limit relative movement using multiple sliding doors and a brake mechanism to secure the doors in position when the door handle is released. A drop window includes features to accommodate for manufacturing tolerances and box frame assemblies that are out of square.

An infrared (IR) sensor for use in a door sensor. The IR sensor may include one or more rows of emitters configured to generate an emission beam. The emission beam may have a width that is at least a width of an opening below the door sensor. The IR sensor may also include one or more rows of receptors configured to receive an evaluation beam. The receptor beam may have a maximum width that is at least the width of the opening. At least a portion of the receptors may be further configured to be one or more of deactivated and ignored, such that the width of the evaluation beam is reduced to correspond with a reduced width of the opening during a closing of a door.
