Abstract: A continuous hinge comprises a first leaf and a second leaf each defining a longitudinal channel, a plurality of barrels defining bores open at each end, each of the barrels including a flange configured to be received in the channels of the first leaf or the second leaf, fasteners attaching the flanges of the barrels in the channels of the first and second leafs, wherein the barrels may be placed end-to-end for axially aligning the bores of the barrels, and a pivot pin extending through the bores of the barrels. The pivot pin is coextensive with the barrels for joining the barrels and the first and second leaves for relative pivoting movement about the pivot pin. The barrels attached to the first leaf are interspersed between the barrels attached to the second leaf in alternating relationship.

Abstract: A threshold system and threshold insert for transitions through doorways. An insert for a threshold saddle to be used with a door includes an elongated member for providing a seal along a bottom edge of the door and to be received in a seat in the saddle. The insert defines a door engagement surface adapted to extend across both the seat and the change in elevation to engage the door to provide the seal. When installed for use, the door engagement surface, the saddle adjacent to the sides of the seat, or both provide an overall slope of at least or approximately 2 units horizontal to 1 unit vertical. A threshold system includes a saddle and the insert. The door or an appurtenant door shoe may have an angled surface to interface with the door engagement surface of the insert.

Abstract: A kit for mounting a frame in a partitioning structure such as a door, and a door including a vision lite. The kit includes a male frame half, a female frame half, and threaded fasteners. The female frame half defines an elongated channel, where the channel includes a bottom with walls extending therefrom with a width adapted to receive a threaded fastener. The first frame piece and the second frame piece are configured to be mounted to each other when the threaded fasteners extend through the first frame piece and into the channel. An installation of such a kit in a door, with window glass, may provide a vision lite in the door. The channel may be configured such that the threaded fasteners penetrate the bottom of the channel when the first frame piece and the second frame piece are installed. The threaded fasteners may be self-tapping screws.

Abstract: A sliding door assembly comprises an upper guide track and a plurality of door panels slidably received in a portion of the upper guide track for movement along the track. A bracket is mounted to a top edge of at least one of the door panels. At least one roller mechanism is secured to the bracket and to each of the door panels. The at least one roller mechanisms are slidably received within the upper guide track. A pair of pulleys is secured to the bracket for carrying an endless cable for rotation around the pulleys. Means are provided for securing the other door panels to the cable. In a first position, the side edges of the door panels are contiguous and a first outer door panel is secured to the cable of the immediately adjacent door at the side edge opposite to the direction of closing movement of the door panels.

Abstract: In a door assembly composed of a door frame, a door having a hinge side and a hinge supporting the door on the frame for pivotal movement of the door between an open position and a closed position, the hinge side of the door facing, and being adjacent to, a portion of the frame when the door is in the closed position, the door is provided with a recess in the hinge side; and the assembly is further provided with at least one projecting element secured to the frame portion to project into the recess when the door is in the closed position and having a mass of thermally intumescent material which is expandable for securing the projecting element to the door upon being heated above a predetermined temperature.

Abstract: A modular ramp system for use with a threshold which has an offset. The modular ramp system includes a number of elements which may be arranged in various combinations in order to conform to offsets of varying height.

Abstract: A locking astragal for attaching to an inactive leaf of a double doorway. In the illustrated embodiment, an elongated astragal casing has a channel and bolt-slide assemblies mounted slidably within the channel. Each bolt-slide assembly includes a latching member and bolt. By depressing the latching member, the latching member can slide through the channel to extend and lock the bolts into indentations in the upper and lower surfaces of the door frame. The bolts may also be retracted back into the astragal to open the inactive leaf. In the illustrated embodiment, each latching member has an integral spring which simplifies fabrication and assembly.

Abstract: A gear hinge having a thrust bearing which is less likely to wear. The hinge may include, in various combinations, gears having relatively small, rounded teeth, hinge members having anodized surfaces, bearings which may be produced by a gas assisted injection molding process and bearings which are relatively hard.
