In example implementations, a horizontal door guide for a vertically stacking door is provided. The horizontal door guide includes a first track and a second track to vertically stack panels of a door along a horizontal line, a drive shaft coupled to a bottom most panel to lift the door vertically, a Geneva drive shaft coupled to the drive shaft, and a lifting cam coupled to the Geneva drive shaft, wherein the lifting cam comprises a rotating lever to separate and lift adjacent panels of the door as the door is opened in a vertical direction by the drive shaft and to push panels into the first track and the second track.

An elevating-type shelter door enables operators to easily open and close in a short period of time, is highly water-tight, and has an excellent durability. A shelter door opens and closes an opening portion when a door body ascends and descends along a guide rail by means of an elevating device. The opening portion is provided on a ceiling of a shelter body. The shelter body is defines an interior space which serves as an evacuation space in an underground. A main body has a central convex portion which slidably fits to the opening portion along an inclination direction in which both the opening portion and the guide rail inclines. An elevating stand is slidably fixed to move along a rest column. The elevating stand is located above the opening portion when the door body is fully ascended and located in the interior space when the opening portion is closed.

A latch assembly connected to the drive unit of a bi-fold door for retaining the bi-fold door secure to a building has elongated straps attached to rotatable latch drums mounted on the outer ends of the drive shaft of the drive unit. Lift drums powered by a motor driven gearbox raise and lower the bi-fold door. Latch assemblies having springs attached to the straps maintain tension on the straps during the opening and closing of the bi-fold door.

A driving mechanism for sliding a windowed frame guided by an outer frame. The sliding frame is attached to two vertical racks which engage with two pinions. The pinions are connected with a joint axle driven by a couple of engaged bevel gearwheels connected to a crank or to an electric motor. The joint axle with the pinions can be housed in a recess carved at the lower plank of a static window's frame. A compact motorized option in which each pinion is coupled with a gearbox and both gearboxes are driven by a central electric motor also can be housed entirely in the static window's recess. The motorized options also include: a control unit for controlling the direction and speed of the sliding, two limit switches for stopping the frame at highest and lowest positions, an electrical overload sensor which detects sudden sliding obstructions and a burglar alarm.

A garage door apparatus includes at least one panel integral to a garage door structure. The panel is rotatable with respect to the surrounding garage door structure, such that, as the panel is rotated, the panel substantially uncovers an opening in the garage door structure. The panel is also selectively retractable into the surrounding garage door structure such that the opening is unobstructed.

In one aspect, a moveable barrier operator is provided that includes a motor, an armature shaft of the motor, and a worm screw assembled with a distal end portion of the armature shaft. The movable barrier operator further includes a worm wheel engaged with the worm and a rotatable drive member connected to the worm wheel. Turning of the armature shaft and worm screw mounted thereto causes turning of the worm wheel and rotatable drive member.
