  • Publication number: 20040206007
    Abstract: An adjustable automatic positioning hinge for a glass door includes a doorframe mount, a body, a spindle, a positioning device, a door bracket and two adjusting screws. The body is attached to the doorframe mount and rotatably holds the spindle. The spindle has an exterior surface and two inclined adjusting flats defined in the exterior surface. The positioning device is mounted in the body to position the spindle. The door bracket holds the spindle and clamps a glass panel. The adjusting screws are mounted in the door bracket and respectively have an inside end abutting the corresponding inclined adjusting flat. Consequently, the adjustable hinge is simple, and small adjustments can be made to align the glass panel with a doorframe of the glass door.

  • Patent number: 6722715
    Abstract: A magnetic lock includes a first metal block securely received in the first frame, and an electrical magnet adapted to connect to a power source to selectively become a magnet and a second frame adapted to be mounted on a door and provided with a second metal block movable respect to the first metal block and the second frame. The second metal block has two retaining recesses to respectively receive therein two clamping blocks. Each of the two clamping blocks is adapted to be movably received in the two retaining recesses and has a recess to receive therein one of the two bolts. When the second metal block is moved by an external force, an inner side face of the recess of each of the clamping blocks abuts a side face of each of the bolts so that the door is still secured to the doorframe.

  • Publication number: 20040020130
    Abstract: An adjustable automatic positioning hinge for a glass door has a doorframe bracket, a body, a spindle, a U-shaped male bracket and a U-shaped female bracket. The U-shaped male bracket and the U-shaped female bracket face and are attached to each other. The body is attached to the doorframe bracket, the U-shaped male bracket, the U-shaped female bracket and the spindle pivot relative to the body. A glass door is clamped between the U-shaped male bracket and the U-shaped female bracket. A spindle anchor hole is formed in central protrusion on the male bracket. The spindle has a first threaded hole and a second threaded hole radially formed in the spindle at an obtuse angle and setscrews screwed through the central protrusion into the first threaded hole and the second threaded hole hold and can be used to adjust the spindle.

  • Patent number: 6536245
    Abstract: A panic door lock includes a housing and a dead bolt that is movable in the housing between an extended position and a retracted position. The dead bolt is spring-loaded and tends to be moved to the extended position. The dead bolt has a slot defined in place therein. A detent has an inner claw adapted to enter the slot and retain the dead bolt in the retracted position as long as the dead bolt is moved to the first retracted position. In addition, a spring-loaded trigger having a tip normally extended out the housing is provided. The trigger is engagable with the detent so that the inner claw may exit the slot and release the dead bolt from the retracted position when the tip of the trigger is pressed into the housing.

  • Patent number: 6526627
    Abstract: An hinge auto-return device for a glass door includes a body containing a longitudinal pivot hole to rotatably receive a pivot pin in the body and a lateral guide hole to movably receive a positioning block in the body. The lateral guide hole extends perpendicular to communicate with the pivot hole. At lest one blind hole is longitudinally defined in the positioning block to mount at least one resilient member in the positioning block. The positioning block has a contact face forced by the resilience of the resilient member to press against a flat segment of the pivot pin when a hinge assembled with the auto-return device is attached to a glass door and hinges the glass door on a doorframe. The positioning block is able to slide smoothly in the guide hole in the body of the auto-return device so that the auto-return device performs reliably and durably.

  • Publication number: 20020066160
    Abstract: An auto-returning device of a hinge for a glass door consists of a body, a spindle rotatably received in a vertically extending spindle hole defined in the body, at least two cylinder like push members respectively and movably received in two horizontal extending through holes defined in the body and in communication with the spindle hole, and at least two elastic members respectively received in opening ends of the push members, whereby close ends of the push members are forced by resilience of the elastic members to press against a flat of the spindle, when a hinge assembled with the auto-returning devices is secured on a glass door and hangs the glass door on a door frame. Each push member of the auto-returning device is able to slide smoothly in the corresponding through hole of the body of the auto-returning device, so that the auto-returning device performs reliably and durably.
