Actuating Force Applied Between Link Pivots; E.g., Over Center Toggle-type Patents (Class 49/330)
  • Patent number: 6446391
    Abstract: A cable actuator for a casement sash includes a cable engager that moves against an opening pull cable and diverts the cable to an elongated path when the sash is closed. When the opening pull cable is tensioned to open the sash, this moves the cable back to a shorter tensioned path that moves the cable engager in a way that initiates opening the sash. Thereafter, the sash opens further in response to winding in of the opening pull cable.

  • Patent number: 5315788
    Abstract: A low friction tape adhesively connected to a movable vehicle door glass for isolating the door glass from a rubber glass run channel and providing a low friction surface for slidably engaging the glass run channel to prohibit glass chatter and noise created by the sliding engagement of the door glass within the glass run channel. The glass run channel is housed within a stationary frame portion of the vehicle door and is utilized to support and guide the door glass as well as seal the door glass to the vehicle door. Separate segments of the low friction tape are applied to the vertical edges and the periphery of the sides of the door glass to prohibit direct contact of the door glass and the glass run channel. Due to the curvature of the door glass, the low friction tape must be applied in several separate segments so that wrinkling of the low friction tape is avoided when applying the tape segments to the door glass.
