Abstract
An electric latch retraction device comprising a housing for receiving a plurality of internal components of the electric latch retraction device. An actuator mechanism is included in the housing, the actuator mechanism is adapted to impart linear movement on a latch, such that the latch is retracted towards the housing. A holding mechanism is also included in the housing, the holding mechanism holds the latch in a fully retracted position.
Claims18
An electric latch retraction device comprising:
- a housing containing an electric motor, wherein said electric motor is adapted to impart linear movement on a latch, such that said latch is retracted towards said housing;
- and
- a holding mechanism mounted in said housing, said holding mechanism adapted to hold said latch in a fully retracted position with a holding strength sufficient to hold said latch in its retracted position with said electric motor off.
An electric latch retraction device comprising:
- a housing containing a plurality of internal components of said electric latch retraction device, said internal components comprising an actuator mechanism adapted to impart linear movement on a latch;
- said internal components further comprising a magnet mounted in said housing, said magnet adapted to hold said latch in a retracted position;
- and
- a bias spring in said housing, said bias spring adapted to position said latch in a latched position.
