  • Patent number: 6460679
    Abstract: A passenger conveyor system includes a handrail adjustment mechanism that automatically adjusts the forces imposed on the handrail. A first length compensation device is positioned on a first side of the handrail drive mechanism. A second length compensation device is positioned on a second side of the handrail drive mechanism. Depending on the direction of handrail movement, one of the two length compensation devices imposes an automatically adjustable amount of tension on the handrail to maintain a desired effective length of the handrail. The length compensation device located on the slack side of the handrail compensates the handrail length by imposing a minimized tension on the handrail. The length compensation device located on the load side of the handrail will be lifted because the traction in the handrail caused by the drive mechanism overcomes any stretch imposed by the length compensation device on the load side.

    Abstract: The glass balustrade of an escalator or moving walkway passenger conveyor is provided with an internally illuminated rail on its side surface. The rail is illuminated by a light beam which is piped up through the interior of the balustrade panels from a light source disposed beneath the outer deck of the passenger conveyor. The light source includes a neon emitter disposed at the focal point of a parabolic mirror so as to provide a parallel band of light which is projected into a lens set. One lens narrows the band of light and the second lens produces a collimated beam from the narrowed light band. The collimated light beam is projected into the bottom of the balustrade panels. The light beam is then serially reflected up through the glass panels to the illuminated rail. The stripe is a semi-circular rod of glass which is glued onto the side of the balustrade, and is formed from a glass having substantially the same index of refraction as the balustrade panel glass.

    Abstract: A balustrade comprises a deck cover disposed on the opposite side to a plurality of steps, a transparent balustrade panel supported by the deck cover, a handrail, a handrail guide frame, secured to an upper edge of the balustrade panel for guiding the handrail moving in synchronism with the plurality of steps, and an illumination device attached directly to the outside surface of the balustrade panel so as to be spaced from the handrail to leave transparent between the handrail and the illumination device. The balustrade further is provided with a supporting pole for supporting the illumination device and containing therein lead wires of the illumination device. The supporting pole has an U-shaped opening and secures an entrance prevention fence with the edge being inserted in the U-shaped opening.

  • Patent number: 4776446
    Abstract: A handrail for transportation apparatus, such as escalators and moving walks, which includes an elongated, extruded elastomeric member having first and second wear strips fixed to inner surfaces of the elastomeric member for contacting a handrail guide. Each wear strip has a substantially U-shaped cross-sectional configuration, including a bight and spaced leg portions, and , in addition to providing low friction wear surfaces, the configuration aids the handrail in resisting derailment from a handrail guide. At least one leg portion of each wear strip has a plurality of spaced slots, or thin webs, which extend inwardly from the end of the leg to facilitate flexing of the elastomeric body member while traversing curved portions of a handrail guide. In another embodiment, a plurality of relatively short, discrete wear strips are spaced apart to collectively define an elongated wear strip, with the spacings being selected to function as flexiblity imparting slots.

  • Patent number: 4762217
    Abstract: The guide rail is one which is adapted to be mounted on a glass balustrade on an escalator. The mounting is accomplished without the need to drill holes in the balustrade or to apply any adhesive to the balustrade. The guide is formed with a groove in its lower surface which receives the top edge of the balustrade. The groove is flanked by gripping legs, one of which can be tightened against the balustrade by means of set screws, in the manner of a vise. The set screws are threaded into a handrail slide portion of the guide and are completely recessed therein so as not to interfere with the handrail.

  • Patent number: 4658946
    Abstract: The balustrade decking profile (14), or handrail guide, for an escalator clips, or "self-fastens" to the top edge of a glass balustrade (10), and presents a minimal yet sufficient sliding area to the handrail (12). This is accomplished by folding or molding a single rigid strip of material (20) as disclosed herein. The profile (14) itself and a method of forming it are disclosed.

  • Patent number: 4618387
    Abstract: A method of splicing a length of extruded handrail having a C-shaped cross-sectional configuration, a substantially flat inner drive surface, and a plurality of spaced, longitudinally extending inextensible members embedded in the body of the handrail. The ends of the handrail are squared, aligned, and butted. Longitudinally extending grooves are cut into the flat drive surface, through and on both sides of the butt joint, in the spaces between the embedded inextensible members. Predetermined lengths of inextensible members and elastomeric material are placed in the grooves, and bonded to the surfaces which define the grooves. In another embodiment, the grooves are extruded into the flat drive surface at the same time the handrail is extruded. In either embodiment, the ends of the handrail may be bonded together prior to, or simultaneously with, the bonding of the inextensible members and elastomeric material with the groove surfaces.

  • Patent number: 4469729
    Abstract: This invention relates to a flexible article comprising rubberlike body having a surface hard film, e.g., a hose, a handrail, a belt or a diaphragm, wherein a fiber layer comprising non-woven or woven fabrics is positioned between the surface hard film and the rubberlike body by use of an adhesive to eliminate generation of the so-called joint cracking phenomenon, i.e., extension of cracking to the rubberlike body accompanying cracking at the hard film caused by any shock.

  • Patent number: 4232776
    Abstract: A variable speed walkway system capable of receiving passengers, accelerating them to above walking speed conveying them over a selected distance at a constant speed, and decelerating them for comfortable exiting is provided. In the preferred form, the system comprises a plurality of rollers driven by a prime mover through individual polyurethane belts to obtain acceleration and deceleration. In a second preferred form, the system comprises a variable speed drive employing one or more belts each of which drives a plurality of rollers. All rollers driven by a single belt accelerate or decelerate in unison. Acceleration and deceleration in this second embodiment is preferably computer controlled. A handrail which accelerates and decelerates with the walkway is provided for both embodiments.
