摘要:
A roller assembly includes a frame (16) defining a doorway (14). A rail (32), which includes at least one supporting surface along at least one side of the rail, is secured to the frame (16). At least one roller (38), which is adapted to roll along the supporting surface of the rail (32), has a tire material (68) that contacts the rail (32). A thermal barrier (62, 70, 72, 76, 80) is positioned to inhibit heat transfer from the rail (32) to the tire material (68).

摘要:
A door assembly has a door header mounted on a frame defining a doorway, a door movably supported on the frame, and a track including at least one supporting surface along at least one side of the track. The track is secured to the door header. The assembly has at least one roller that is adapted to roll along the track. The roller has a rim portion adjacent a hub portion, and a tire material surrounding the rim portion that contacts the track. The roller is at least partially covered with a thermal barrier between the tire material and at least one of the rim portion and the hub portion to prevent heat transfer to the tire material.

An assembly for preventing a fire resulting from the outgassing of a lithium battery in an electronic door lock includes a lithium battery, a circuit board, and a thermal insulation. The lithium battery and circuit board are housed within the electronic door lock. The thermal insulation is arranged between a door interfacing side of the electronic door lock and either or both of the circuit board and lithium battery. Another thermal management technique for preventing fire resulting from the outgassing of a lithium battery in an electronic door lock is achieved by using a battery cover that is selectively movable away from the circuit board or ignition source in response to temperature rise to ensure the lithium battery does not reach a critical temperature that may cause outgassing in close proximity to the ignition source.

An exemplary assembly includes at least one elongated tension member. A jacket covers at least some of the tension member. The jacket comprises a polymer material. The assembly includes a flame retardant selected from a group consisting of a halogen-free melamine based intumescent or a filled polymer having a nanoscale filler chemically bonded to a matrix phase.

An exemplary assembly includes at least one elongated tension member (26). A jacket (34) covers at least some of the tension member (32). The polymer jacket (34) comprises a polymer material including a melamine based geometry stabilizer that facilitates maintaining the jacket material near the tension member if the assembly is subjected to a high temperature condition.
摘要:
A method of making a passenger conveyor handrail includes forming a drive member having a plurality of longitudinally spaced drive surfaces. The drive member has a longitudinal stiffness for maintaining a desired spacing between the drive surfaces. The drive member is inserted into a molding device. A gripping surface portion of the handrail is formed using the molding device such that the gripping surface portion and the drive member are secured together. Another method includes forming a belt drive member having a plurality of teeth that establish a plurality of longitudinally spaced drive surfaces. The belt has a longitudinal stiffness for maintaining a desired spacing between the drive surfaces. Each of the teeth extends across an entire width of the belt. The belt is secured to a gripping surface portion of the handrail.
