An exemplary modular hold-open device is configured for use with a door closer comprising a body, a pinion rotatably mounted to the body, and an armature connected with the pinion. The modular hold-open device is configured to be mounted to the door closer, to selectively prevent rotation of the pinion by exerting on the pinion a resistive torque in a door-opening direction, and to cease exerting the resistive torque in response to a door-closing torque on the pinion exceeding a threshold torque to thereby permit rotation of the pinion in the door-closing direction.

There is disclosed in one example, an encasement for a mobile computer, including: an external casing in a clamshell form factor, the external casing including a base, a secondary display chassis hingedly connected to the base at a secondary hinge, and a primary display chassis hingedly connected to the secondary display chassis at a primary hinge disposed at a removed edge of the secondary display chassis from the secondary hinge, the primary display chassis to substantially overlay the secondary display chassis and the base when the primary hinge is in a closed position; and pivot means disposed to substantially bias the secondary hinge against movement from a selected position in at least one direction in the absence of an electrical input.

An exemplary lockset includes a mortise case, a magnet assembly mounted in the mortise case, and a manual actuator operable to move the magnet assembly between a coupling position in which a first magnet of the magnet assembly is aligned with a reference point and a decoupling position in which the first magnet is misaligned with the reference point. In certain embodiments, the magnet assembly further includes a second magnet having an opposite polarity as the first magnet, and the second magnet is misaligned with the reference point when the magnet assembly is in the coupling position and is aligned with the reference point when the magnet assembly is in the decoupling position.

A vehicle door arranged on a vehicle body and a device for manually and/or electromotively adjusting the vehicle door relative to the vehicle body including an output element moved on adjustment of the vehicle door and a switching device configured to switch between a coupling state and a freewheeling state, and a control device. The switching device configured to couple the output element to a further assembly in the coupling state and to disengage it from the further assembly in the freewheeling state such that the output element is movable with respect to the further assembly. At least one sensor device configured to detect a signal indicating an occupant's wish to get out of the vehicle, and configured to evaluate the signal for detecting an exit wish and actuate the switching device to switch into the coupling state.

The present disclosure relates to a wing hinge for a field device housing, including: a first wing having a first and a second holding device, the first holding device configured to connect to the field device housing and to move the first wing about a first axis; a second wing having a third and a fourth holding device, the third holding device configured to connect to the second holding device and to move the second wing relative to the first wing about a second axis, wherein the fourth holding device is connectable to a housing cover as to move the housing cover relative to the second wing about a third axis; and a tensioning element in contact with the first wing and the second wing and configured to move the first wing relative to the second wing about the second axis from a first position into a second position.

A multi-link door hinge capable of facilitating the closing of a door and implementing the shock-absorbing performance of the door during the closing thereof. To this end, the multi-link door hinge includes: a main frame mounted to a main body of an object having a door; a door frame mounted to the door; a body frame rotatably connected to a first side of the main frame; an inner link and an outer link connecting the door frame to the body frame; a plate spring link allowing the outer link to be rotatably connected to the main frame; a locking piece rotatably mounted between side walls of the inner link; an elastic member; and a hook, a first side of which is fixed in the body frame and a second side of which is configured to be held in a second side of the locking piece.

There is disclosed in one example, an encasement for a mobile computer, including: an external casing in a clamshell form factor, the external casing including a base, a secondary display chassis hingedly connected to the base at a secondary hinge, and a primary display chassis hingedly connected to the secondary display chassis at a primary hinge disposed at a removed edge of the secondary display chassis from the secondary hinge, the primary display chassis to substantially overlay the secondary display chassis and the base when the primary hinge is in a closed position; and pivot means disposed to substantially bias the secondary hinge against movement from a selected position in at least one direction in the absence of an electrical input.

A heavy duty full energy, encoder driven non-handed electric door operator for industrial and commercial use a motor and an encoder configured to receive an external set of predetermined instructions. A motor mounting bracket connects the motor to a multi-layer housing. A controller is in electronic communications with the encoder and transmits external sets of predetermined instructions. Internally, the door operator contains a plurality of transfer shaft assemblies in communication with each other and connected with the motor at one end and an output shaft at the other end. The output shaft terminates at each end in a nondetachable spline. A detachable mounting plate serves as a base. The door operator operates heavy swing doors external to a building where the swing doors are required to be open or remain open in strong wind conditions.

Door assemblies, aircraft including door assemblies, and method for making door assemblies are provided. In one example, a door assembly includes a hinge subassembly and a door pivotally coupled to the hinge subassembly. The door has a channel disposed therein with a holding member disposed proximate a channel distal portion. A sliding member is movably disposed in the channel. An arm has a first portion pivotally coupled to a second hinge subassembly and a second portion pivotally coupled to the sliding member to move the sliding member as the door moves between a closed position and an open position. A stay member is coupled to the sliding member to move towards the holding member which holds the stay member in position when the door is moved to the open position to hold the door open.

An integrated magnetic catch used to hold a horizontal hinged oven door open at a selected set partially open position. A pin is used to hold the two plates together and acts as a pivot point. Attached to a stationary plate is a bracket that houses a magnet. This bracket is formed having a preset angle that correlates with the degree that the door is to be opened. When the rotating hinge makes contact with the bracket, the magnetic force holds the door open at a selected angle.
