Abstract:
The van (10) has a sliding door (14) mounted on rollers (22, 24 and 30) that are supported by and slidable in tracks (16, 18 and 20). An opening and closing module (50) is mounted inside the van adjacent to the center track (18). A front cable (74) is attached to the front cable drive pulley (144), and extends from the pulley through a front cable roller guide assembly (54) and is attached to the hinge and roller assembly (26). A rear cable (100) is attached to the rear cable drive pulley (136) and extends from the pulley through a rear cable roller guide assembly (56) and is attached to the hinge and roller assembly (26). The front and rear cable drive pulleys (136 and 144) each have a large diameter spiral cable groove (164), a small diameter cable groove (208) and a transition cable groove 210. A motor (126) rotates the front and rear cable drive pulleys to move the sliding door. The small diameter cable grooves (208) drive the sliding door (14) when the door is in the forward portion of the tracks. The large diameter spiral cable grooves (164) drive the sliding door when the door is in the center and rear portions of the tracks. Fixed idler rollers (226 and 254) guide the front and rear cables (74 and 100) to and from the cable drive pulleys (136 and 144).
Abstract:
A door operator mechanism which has a motive power source and drive and a manual drive for use with a manual source of power. A mechanism is included which by the simple expedient of pulling a chain or cable disconnects the power source and associated driver and connects the manual drive for use of a manual source of power. Release of the cable causes the reverse.
Abstract:
An operating mechanism for the window in a motorcar door and the like includes guiding devices, including at least one deflecting element, which engage a wire, cable or other elongated tension member and guide the tension member on the door in a loop-shaped path when the tension member is driven in the path alternatively in two opposite, longitudinal directions. The motion of the tension member is transmitted to the window. The tension member stretches under the longitudinal stresses exerted thereon by the drive and the window and needs to be tensioned. According to the invention, a spring in a permanently stressed condition biases the deflecting element in a direction to lengthen the path of the tension member and for thereby compensating for slack in the engaged portion of the tension member when the tension member moves in one longitudinal direction, whereby the spring reaches a partly relaxed condition. A protecting mechanism protects the spring against return from the partly relaxed condition toward the stressed condition when the tension member moves in the opposite direction.
Abstract:
A hinge structure is disclosed for hingedly joining a cover or lid member with a base or housing member of an overall unit, such as a control lens disinfector, or the like. The base or container member carries, in opposing side wall portions, a pair of coaxial, axially spaced cylindrical bores or apertures, while the cover member carries, in opposing side wall portions, a pair of coaxial, axially spaced and oppositely outwardly extending rod-like pins or pintle members. The axial spacing of these pins or pintles is similar to that of the bores or apertures of the base member. A pair of slots or openings are provided in an end wall of the cover member, being generally adjacent the confluences of the respective side walls with the end wall, one such slot being disposed immediately axially inwardly of each of the pin or pintle members. Advantageously, the slots provide for resilient movement of the side wall portions of the cover member adjacent the pin or pintle members. This resilient movement permits inward compression of these side wall portions for alignment of the pin or pintle members with the cooperating base member bores or apertures. Upon cessation of such compression, the cover member side wall portions resiliently return to their original shape, thus inserting the rod-like members for pivotal or rotative movement within their cooperating base member bores to define the assembled hinge structure.
Abstract:
This invention relates generally to hanger devices for suspending door panels and the like, and more particularly to the combination with a hanger structure of a manually shiftable latch device to facilitate attachment and detachment of a top-hung door panel. The present application discloses a hanger device of the type which includes a carriage movable within an upper track and having means in the form of a depending pin for accommodating a complementary fitting attached to the upper margin of the door panel. The fitting attached to the upper edge of the panel includes an open-ended slot for receiving the lower extremity of the above-mentioned carriage pin. A pivotally supported latch member, when in one shifted position permits lateral insertion of the carriage pin within the open-ended slot, and when in another shifted position prevents lateral movement or dislodgement of the pin from the slot. This latch device includes a handle member projecting beyond a bounding plane of the door which may be manually manipulated to move the latch member between the two above-mentioned positions.
Abstract:
A door operator for driving a track guided door through opening and closing cycles, including a rotating shaft and drive member movable therealong in response to rotation wherein the drive member is resiliently coupled to a door. A locking mechanism is provided for locking the door in closed position and an emergency device enables opening of the door when power is not available.
Abstract:
Der Bedienkomfort für ein Fenster soll mit Blick auf das Öffnen eines Flügels und die Beibehaltung einer Offenstellung des Flügels verbessert werden. Das Vorspannbauteil hat dazu eine erste, mit einem Flügel (2) der Vorrichtung (100) in Kontakt bringbare Kraftübertragungskomponente (15), und weiter eine zweite, mit einem Rahmen (1) der Vorrichtung (100) in Kontakt bringbare Kraftübertragungs-Komponente (16). Eine mechanische Vorspanneinrichtung (18), die mit der ersten Kraftübertragungs-Komponente (15) und der zweiten Kraftübertragungskomponente (16) gekoppelt ist, ist ausgebildet, eine in Richtung einer Vergrößerung eines Öffnungsspaltes (2a) zwischen dem Flügel (2) und dem Rahmen (1) wirkende Kraft (F) hervorzurufen.
