Security-enhanced garage door opener system
This invention is about an improved garage door opener system, with design features for preventing garage door break-in from outside of the garage using an object such as a hanger. Typically, a person pulls down a cord connected to a release handle to release emergency release of a garage door opener, allowing the door to be manually open or closed. An unauthorized person may attempt to pull down the cord using a hanger from outside the garage or to pull or push down the release handle, to open the door from outside and gain unauthorized entrance. The improved garage door opener system provides a mechanism to reverse the pulling direction of the cord and also protects release handle from being accessed from outside the garage, for increased security.
