Abstract:
Disclosed is a motor unit including: an electric motor; a motor housing (6) configured to accommodate the electric motor; and a control substrate (70) including a sensor element (72S) to detect a position of an inner rotor of the electric motor in a rotational direction. The motor housing (6) includes a substrate accommodating portion (80) configured to accommodate at least a portion of the control substrate (70); a positioning portion (81) that is formed in the substrate accommodating portion (80), and positions the control substrate (70); and a screw configured to fix a stator of the electric motor to the positioning portion (81).
Abstract:
A power drive moves a movable closure between an open position and a closed position with respect to a portal defining a passage through a barrier. The power drive can include an elongated drive member connected to the movable closure and a ball nut drive assembly for selectively moving the drive member longitudinally to position the movable closure between the open position and the closed position with respect to the passage through the barrier. The barrier can define at least a portion of a stationary structure or a vehicle, where the passage allows access within the structure or the vehicle. The movable closure can include a sliding door, hatch, window, roof panel or the like. The elongated drive member can be a compound drive member having at least one gear or tooth-like member extending helically around in uniformly spaced turns about a core of the drive member to form a rigid or resilient screw-like portion capable of being driven by operable engagement with the recirculating ball nut drive assembly. A flexible portion, such as a push/pull cable can be attached to one end of the screw-like member to allow the power drive to move a movable closure along a curved or other non-linear path.
Abstract:
A power drive moves a movable closure (D) between an open position and a closed position with respect to a portal defining a passage through a barrier. The power drive can include an elongated drive member (34) connected to the movable closure and a ball nut drive assembly (64) for selectively moving the drive member longitudinally. The elongated drive member (34) can be a compound drive member having at least one gear or tooth-like member extending helically around in uniformly spaced turns about a core of the drive member to form a rigid or resilient screw-like portion (88) capable of being driven by operable engagement with the recirculating ball nut drive assembly (64). A flexible portion, such as a push/pull cable (90) can be attached to one end of the screw-like member to allow the power drive to move a movable closure along a curved or other non-linear path.
Abstract:
A device for moving at least one door leaf, includes a fixed beam that is fixed to the frame, a moving beam that is connected to the fixed beam by swinging rails which allow it to move transversely with respect to the axes of elongation of the fixed and moving beams, a motor which drives the leaf in a movement parallel to the axis of elongation of the moving beam and which, during the swinging of the leaf, also drives a drive cam which is provided with a slot in which there is engaged a pin that is fixed to the fixed beam, and a central roller which is connected to the moving beam and circulates in a groove in the fixed beam during the movement of the leaf.
Abstract:
A curtain integrated door regulator structure includes a motor, a drive gear, a drum retainer, a glass driving drum, a curtain driving drum, gear keys and key grooves. The motor generates a rotational driving force to rotate a driving shaft. The drive gear has a shaft receiving hole into which a driving shaft of the motor is fitted. The drum retainer has a spiral groove shaft supporting part spirally coupled to a spiral protrusion disposed on an outer circumference of the drive gear. The glass driving drum and the curtain driving drum are rotatably received in the drum retainer and disposed at an outer side of the drive gear. The gear keys are disposed on the outer circumference of the drive gear. The key grooves are formed in the glass driving drum and the curtain driving drum, respectively, and have a shape corresponding to that of the gear keys.
Abstract:
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.
Abstract:
Die Erfindung betrifft eine Verriegelungsvorrichtung (10) für Schwenkschiebetüren von Fahrzeugen, insbesondere von Fahrzeugen für den öffentlichen Personenverkehr, umfassend mindestens ein in Längsrichtung des Fahrzeugs verschiebbares Türblatt und einen Antrieb (50) zur Bewegung des Türblatts zwischen einer geschlossenen und einer geöffneten Stellung, wobei die Verriegelungsvorrichtung (10) ein Gestänge (20; 30; 40) umfasst, das für eine Verriegelung der Tür in der geschlossenen Stellung in eine Übertotpunktlage bringbar ist. Sie ist dadurch gekennzeichnet, dass die Verriegelungsvorrichtung (10) eine Grundplatte (11) aufweist, auf der eine Verriegelungsplatte (20) und ein Umlenkhebel (40) in jeweiligen Lagern (13; 14) drehbar in einer Ebene parallel zur Ebene der Grundplatte gelagert sind. Der Umlenkhebel (40) und die Verriegelungsplatte (20) sind über einen jeweils gelenkig an diesen gelagerten Verriegelungshebel (30) miteinander verbunden, wobei der Umlenkhebel (40), der Verriegelungshebel (30) und die Verriegelungsplatte (20) durch Anlenkung des Verriegelungshebels (30) in eine Lage bringbar sind, in der die Verbindungslinie (VV) zwischen dem Lager (13) des Umlenkhebels (40) und dem Gelenk (32) zwischen dem Verriegelungshebel (30) und der Verriegelungsplatte (20) und die Verbindungslinie (VU) zwischen dem Lager (13) des Umlenkhebels (40) und dem Gelenk (31) zwischen dem Umlenkhebel (40) und dem Verriegelungshebel (30) in Übertotpunktstellung stehen. Diese Übertotpunktstellung ist durch eine entgegen gesetzte Anlenkung des Verriegelungshebels (30) auflösbar, wobei die Verriegelungsplatte (20), der Umlenkhebel (40) und der Verriegelungshebel (30) auf der gleichen Seite der Grundplatte (11) angeordnet sind.
