Abstract:
An object sensor system is mounted on a garage door controlled by an electric garage door opener. The sensor system senses objects directly in the travel path of the door's leading edge. Each object sensor of the system comprises a mounting plate for permanent attachment to the garage door near a leading edge of the door, an upper hinge plate hingeably connected to the mounting plate, a lower hinge plate hingeably connected to the mounting plate and a connecting hinge plate connected to the upper and lower hinge plates. The plates are connected to move in concert. Each of the object sensors also includes a bracket having a first leg attached to the connecting hinge plate and a second leg extending horizontally towards the mounting plate and under the leading edge of the door. An electronic sensor is mounted on the bracket's second leg at a distal end to transmit or receive a light beam. An anti-friction slide pad is attached to an underside of the second leg of the bracket to allow the bracket with its sensor to move inwardly as the door's leading edge approaches ground surface. As the door travels downwardly, each electronic sensor moves with the door until the bracket hits ground surface, at which time, the upper and lower hinge plates are forced to pivot upwardly thereby forcing the bracket with its electronic sensor to move backwardly away from the garage door.
Abstract:
In a system for automatically opening or closing a sliding door or the like for a vehicle, an undesired clamping of an object between the door and the vehicle body, resulting in increased tension force in the wire moving the door, is sent early and relieved quickly. The wire (4) is solidly secured to the sliding door and wound onto a drum (10) to open or close the door by a motor driving the drum, and two tensioners (11a and 11b) are provided respectively on opposite sides of the drum and between the drum and door. Each sensor has a movable part (19) positioned in accordance with the tension force in the wire passing through the tensioner, sensor plates (20) are provided on the movable parts of the tensioners, and magnetic sensors (21) are provided to detect the moving speeds of the plates. When the moving speeds of the plates are larger than a predetermined value, preset in advance, in cases other than when the door is at a fully closed or fully opened condition, a controller concludes that some object has been clamped between the door and the vehicle body and immediately relieves such clamping.

Each of the corner members includes a spring biased roller whereby the rollers are self-leveling at each of said corners. A clip is arranged to adjust the roller to a plurality of inwardly and outwardly extensions relative to the top and bottom panel members. The arrangement is such that the corner members are effective as an installation guide for the sliding panel and impart an anti-rattle feature thereto.
Abstract:
A van door slidable in tracks (16, 18 and 20). An operating module is mounted inside the van adjacent center track 18. A front cable attached to drive pulley (144) extends through guide assembly (54) to hinge and roller assemble (26). A rear cable attached to drive pulley (136) extends through guide assembly (56) to hinge and roller assembly (26). The 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 rotates the drive pulleys. The small diameter cable grooves drive the door when the door is in the forward portion of the tracks. The large diameter spiral cable grooves drive the door when the door is in the center and rear portions of the track. Fixed idler rollers (226 and 254) are positioned relative to the cable drive pulleys to insure that the total cable in the continuous cable loop is substantially the same when the cable is driven by the small diameter cable grooves as when the cable is driven by the large diameter spiral cable grooves. A cable tension system (220) maintains cable tension. A slack cable take-up pulley (174) on the drive pulley (136) takes up slack cable to set cable tension and is then locked in position.

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.
