The invention relates to a door arrangement (1) for a door with a first enclosed volume, the arrangement permitting a sealed connection between the first enclosed volume and a second enclosed volume, and comprising a flange (2) defining passage opening and a passage axis (O) perpendicular to the opening plane, a door (4) pivotably mounted on the flange (2) and a chute for discharging (10) components which is movable between a discharge position in which the chute is positioned opposite the passage opening and a position in which the chute is spaced apart from the passage opening, the chute being attached to the flange (2) by means of a first double-jointed link mechanism (11) comprising a first link (12) arranged to permit a rotational movement about an axis (C) parallel to the passage axis (O) of the passage opening and a second link (13) arranged to permit a rotational movement about an axis (D) perpendicular to the passage axis (O) of the passage opening.

An exemplary apparatus includes a modular, self-contained spring cage and a spindle. The spring cage includes a housing and a clock spring mounted in the housing, and the clock spring includes a first leg and a second leg. The spindle extends through the spring cage, and is rotatable from a home position about a longitudinal axis in each of a first rotational direction and a second rotational direction. Rotation of the spindle from the home position in the first rotational direction causes pivoting of the first leg while the second leg remains stationary, thereby causing the clock spring to urge the spindle to return to the home position. Rotation of the spindle from the home position in the second rotational direction causes pivoting of the second leg while the first leg remains stationary, thereby causing the clock spring to urge the spindle to return to the home position.

A system with a base may be mounted on a vehicle, and a carriage assembly that may be movably connected to the base and may move with respect to the base. The carriage assembly may include a motor including a motor output shaft and motor housing, and a driving mechanism may couple to a door and to the motor output shaft or the motor housing. The carriage assembly may also include a coordination bar may be coupled to the motor output shaft or the motor housing, the motor output shaft or the motor housing may rotate the coordination bar responsive to operation of the motor. At least one linkage assembly may extend or retract to move the carriage assembly to move the door between an open position and a closed position based on rotation of the coordination bar.

A two-stage open structure of a vehicle door includes a first-stage door configured to be rotated open with respect to a first hinge, a second-stage door configured to be rotated open together with the first-stage door with respect to a second hinge, a cross member, and a motor module positioned on the cross member and configured to apply a driving force to the first hinge and the second hinge individually.

A locking device for a top of a convertible vehicle is proposed, comprising a locking support (22), a locking hook (28), which can be shifted in a translational and rotational manner so as to be displaced between a release position and a locked position, and a driving mechanism for the locking hook (28), said driving mechanism comprising a driving motor (64) and driving a slide (36) movable on the locking support (22). The slide (36) is connected to a driving section of the locking hook (28) via a pull-link arrangement (46) in such a manner that the locking hook (28) undergoes a pivoting movement when the slide (36) is moved. The locking support (22) has an insert having a guiding track for a guiding element which is arranged on the pull-link arrangement (46) or on the locking hook (28), and the guiding track defines a pivot position of the locking hook (28) with respect to the locking support (22).

A collapsible gate includes a first side column, a second side column, a collapsible barrier assembly, a receiver, and a powertrain. The collapsible barrier assembly is disposed between the first and second side columns. The collapsible barrier is configured to transition between a collapsed position and a raised position. The receiver is disposed between the first side column and the second side column and is configured to receive at least a portion of the collapsible barrier assembly when it is in the collapsed position. The receiver has a first end coupled to the first lower portion of the side column and an opposite second end coupled to the second lower portion of the second side column. The powertrain is configured to transmit mechanical power to the collapsible barrier assembly to facilitate transitioning the collapsible barrier assembly between the collapsed position and the raised position.

A thermal door release system is provided that includes a plurality of temperature sensors arranged within multiple environments; a controller; and a release apparatus; wherein the controller, using data from the temperature sensors, monitors the temperatures of the individual environments and when a temperature for an environment reaches a set temperature threshold for that environment, causes an action such as the release apparatus to operate a door to a specified position. The set points and actions to be taken can be set per environment by a user, such that different environments will have different set points. In an embodiment, the system can support staged logic such that at various different user-defined set point temperatures for an environment, specified actions can be taken, for example, sending an email to the facilities manager when the temperature is significantly above normal and closing the door when it reaches a higher set point value.

A personnel access door assembly of an opposing wing of a mine ventilation door. The personnel access door includes a frame including a top portion, a bottom portion, a first post portion and a second post portion, the top frame portion and the bottom frame portion coupled to respective top and bottom ends of the first post and second post portions. The personnel access door further includes sets of trolley wheels affixed to the top or bottom of the frame to engage a top rail or bottom rail affixed on the opposing wing.

A system with a base may be mounted on a vehicle, and a carriage assembly that may be movably connected to the base and may move with respect to the base. The carriage assembly may include a motor including a motor output shaft and motor housing, and a driving mechanism may couple to a door and to the motor output shaft or the motor housing. The carriage assembly may also include a coordination bar may be coupled to the motor output shaft or the motor housing, the motor output shaft or the motor housing may rotate the coordination bar responsive to operation of the motor. At least one linkage assembly may extend or retract to move the carriage assembly to move the door between an open position and a closed position based on rotation of the coordination bar.

An exemplary apparatus includes a modular, self-contained spring cage and a spindle. The spring cage includes a housing and a clock spring mounted in the housing, and the clock spring includes a first leg and a second leg. The spindle extends through the spring cage, and is rotatable from a home position about a longitudinal axis in each of a first rotational direction and a second rotational direction. Rotation of the spindle from the home position in the first rotational direction causes pivoting of the first leg while the second leg remains stationary, thereby causing the clock spring to urge the spindle to return to the home position. Rotation of the spindle from the home position in the second rotational direction causes pivoting of the second leg while the first leg remains stationary, thereby causing the clock spring to urge the spindle to return to the home position.
