Having Hinged Plates Forming Steps Patents (Class 198/327)
  • Patent number: 11299933
    Abstract: A system for forming a step protruding from a post (e.g., tree) includes a spine, a post fastener, and a step. The spine is strapped or screwed to the post via the post fastener such that the spine extends generally parallel to the post (i.e., vertically). The spine includes a length of tubing and an alignment plate. The length of tubing extends vertically along the post when installed (i.e., assembled) on the post. The alignment plate is attached to the length of tubing, typically at one or both ends of the tubing. The alignment plate extends laterally from the length of tubing to limit rotation of the tubing about a vertical axis thereof by interacting with the post when the spine is installed on the post. The step engages the spine such that the step is supported by the spine when the system is installed on the post. The step extends generally perpendicularly from the spine and post.

    Abstract: The step (1) comprises cheeks (5) which are manufactured from deep drawing sheet metal, and a tread element (22) and a deep drawn seating element (24). The arc (BO1) of the seating element (24) follows a first radius (R1) in the upper region and a second radius (R2) in the lower region, wherein the second radius (R2) is somewhat smaller than the first radius (R1). The sheet (BO1) of the seating element (24) merges smoothly at the line (ÜR) from one radius into the other radius. By way of the two radii (R1, R2), the size of the step gap between the tread element (22) and the seating element (24) of the adjacent step is independent of the position of the step gap; the step gap always remains very small, for example smaller than 2.8 mm. As a result, the risk of clothing items, sharp objects, shoes, children's fingers and so on getting jammed is reduced considerably.

    Abstract: In the escalator with a high speed inclined section, a shape of an auxiliary rail is set in a section between a forward path side horizontal section and a forward path side constant inclined section of a circulation path such that, of steps adjacent to each other, a moving track of a relative position of a step on a lower step side with respect to a step on an upper step side is the same as a surface shape of a riser of the step on the upper step side.

  • Patent number: 6450316
    Abstract: An escalator system includes a protective flange assembly along edges of the steps having step flanges. In one example, a first step flange member is adjacent each edge of each step and moves with the step along the escalator path. The first panel member remains stationary relative to the step along the entire path. A second panel member is associated with a corresponding link in the drive chain and remains stationary relative to the link along the entire path of the escalator. The first panel members and second panel members cooperate to provide a continuous barrier along each edge of the steps along the escalator path.

  • Patent number: 5944164
    Abstract: A method for the assembly/dismantling of axles and/or the steps or pallets of escalators or moving sidewalks includes providing between parallel extending traction elements a plurality of axles and connecting the axles to the traction elements. The axles are provided with flattened zones in assembly regions for the steps or pallets and the assembly regions are provided, respectively, with an approximately eyelet-shape designed that has a corresponding slot fitted onto the respective flattened zones of the axles. The axles are turned at a predetermined angle around their longitudinal axis relative to the steps or pallets and subsequently at least one connecting element is inserted into a respective one of the assembly regions for securing the axles relative to the steps or pallets.

  • Patent number: 5899314
    Abstract: A terminal rail for a passenger conveyor including an inner and outer guide rails is disclosed. According to the terminal rail, a portion on which the rear wheel roller is initially contacted with the outer guide rail includes a damper placed between an end of a straight portion of the outer guide rail and a desired position of a turning portion to damp impact produced when the rear wheel roller of the step travels from the inner guide rail to the outer guide rail of the terminal rail.

  • Patent number: 5829570
    Abstract: A terminal rail system for an escalator includes an escalator step having a step front roller and a step rear roller, an upper guide rail for guiding the step front roller, a lower guide rail for guiding the step rear roller, a semicircular inner casing and outer casing that are connected to each other by a side plate and engaged to a curved portion of the lower guide rail for guiding the step rear roller through a channel formed between the casings, a buffer attached to the semicircular outer casing to reduce an impact caused by the proceeding step rear roller. The terminal rail system decreases an impact resulting from the step rear roller, thereby decreasing pulsation or vibration of the step and obtaining an extended longevity of the step rear roller and the terminal rail.

  • Patent number: 5595278
    Abstract: A pallet for a conveyor includes a first connector, a second connector, and a link engaging the connectors of adjacent pallets. The link permits the connectors of adjacent pallets to move relative to each other through an arcuate path. This arrangement for adjacent pallets results in a connection between the pallets that accommodates the varying distance between the adjacent pallets as they travel through a curved path.

  • Patent number: 5219060
    Abstract: The step axle of an escalator is made with an inner, higher strength core piece and an outer, lower strength sleeve. The core is telescoped into the sleeve with opposite ends of the core projecting beyond corresponding outer ends of the sleeve. The step chains and step chain rollers are mounted on the harder outer ends of the core. The higher strength of the core prevents deformation of the composite axle from stresses imparted to the ends of the axle by the chains and rollers. The sleeve with its reinforcement of the core prevents the axle from bending in its center section when loads from the escalator steps are transmitted to the step axle from passengers on the escalator.

  • Patent number: 5205391
    Abstract: A system is provided for adhesively attaching a first member to a generally planar portion of a second member. The system includes an attachment clip having a first, generally planar portion and a second portion remote from the first portion adapted for attachment to the first member. A generally planar base is sandwiched between the planar portion of the attachment clip and the planar portion of the second member. An adhesive is located between the base and the planar portion of the second member. A weld is provided between the base and the planar portion of the attachment clip. Therefore, "peel" stresses are eliminated between the base and the planar portion of the second member, as the weld develops a tensile load between the base and the planar portion of the attachment clip.

  • Patent number: 5072821
    Abstract: An escalator or people mover having steps or pallets which are supported by axles that are driven by a step chain, utilize a split bearing disposed between the axle and the step or pallet. The split bearing allows for rapid replacement of a worn bearing. The split bearing has a shaped outer portion for cooperating with the step or pallet to prevent rotation of the bearing relative to the step.

  • Patent number: 4130192
    Abstract: Transportation apparatus including an endless belt having platforms, pallets or steps attached thereto. The endless belt is driven in a guided loop through load bearing and return runs interconnected by turn-arounds at the ends of the loop. Guide rollers and guide tracks cooperate to guide the endless belt, with the guide tracks associated with the load bearing and return runs being connected in the turn-arounds via dynamic transition apparatus including cooperative guide track structure which enables normal manufacturing and assembly tolerances to be observed while automatically compensating for wear. The apparatus constantly seeks the best adjustment mode, providing smooth operation with minimal noise and vibration.
