Description

BACKGROUND



[0001] Passenger conveyors, such as moving walkways or escalators, include a set of moving steps that carry individuals between landings at opposite ends of the conveyor. Passenger conveyors have many structural and moving parts and installing the system is challenging. For example it is time-consuming and difficult to establish a proper alignment of balustrade panels on opposite sides of the steps. If the panels are not properly aligned with each other and the rest of the conveyor assembly the overall appearance of the conveyor will be compromised. Additionally, the balustrade typically at least partially supports the handrail and proper balustrade position is necessary to facilitate proper handrail movement and operation.

DETAILED DESCRIPTION



[0024] Embodiments of this invention facilitate quicker and easier passenger conveyor installation and assembly. An example disclosed embodiment facilitates installing balustrade panels by assisting a technician in positioning balustrade positioning components relative to the steps of the passenger conveyor. The example embodiment also facilitates accurately installing side decking components.

[0025] Figure 1 diagrammatically illustrates a passenger conveyor 20. In this example, the passenger conveyor 20 is an escalator. In other embodiments, the passenger conveyor is a moving walkway. The passenger conveyor 20 includes a plurality of steps 22 that are moveable to carry passengers between landings 24 and 26. Balustrade panels 28 are situated on opposite sides of the steps 22. The balustrade panels provide at least some support for handrails 30 that move with the steps 22. The components and operation of the example passenger conveyor 20 are known.

[0026] Figures 2 and 3 illustrate an example embodiment of a device 40 that facilitates installing components of a passenger conveyor such as the conveyor 20. The device 40 includes a base 42 that is configured to be situated on at least one of the steps 22 of the conveyor 20. The base 42 includes a plurality of beams or rods 44, 46, 48 and 50 that establish a rectangular frame. In this example the frame of the base 42 has a width corresponding to a width of the steps 22.

[0027] The base 42 includes a plurality of tabs extending from the surface of the base 42 that is configured to be received on one of the steps 22. The tabs in this example include tabs 52 secured to the beam 44 with a portion of the tabs 52 extending beyond the beam 44 where the tabs 52 can be received against a front edge of a step 22 to set a position of the device 40 relative to the front edge of the step. The tabs 52 prevent movement of the base 42 of the device 40 relative to a selected step 22 in a first direction (e.g., front-to-back).

[0028] Other tabs 54 are situated perpendicular to the tabs 52. The tabs 54 are situated on the base in positions where the tabs 54 can be at least partially received in grooves on a step 22. The tabs 54 establish a lateral position of the device 40 relative to a selected step 22 and prevent movement of the base 42 relative to a selected step in a second direction (e.g., side-to-side). The tabs 52 and 54 collectively serve to prevent movement of the base 42 of the device relative to a selected step 22 in two perpendicular directions. Maintaining a stable position of the device 40 relative to a selected step 22 facilitates accurate installation or positioning of components of the conveyor 20.

[0029] The example device 40 includes supports 56 that support a template 60 at a selected angle relative to the base 42. In this example, the angle between the template 60 and the base 42 is between 30 degrees and 45 degrees. An example embodiment includes an angle of 35 degrees. The angle at which the template 60 is situated relative to the base corresponds to an angle of the balustrade panels 30 relative to a tread surface on the steps along the sides of the conveyor 20 once those panels are installed.

[0030] The template includes a plurality of beams or rods 62, 64, 66 and 68. Balustrade position indicators 70 are secured to the beams 66 and 68, respectively. The balustrade position indicators 70 comprise plates having lower edges 72 aligned relative to the base 42 at the angle at which the balustrade panels 30 will be situated once installed.

[0031] In this embodiment, depth gauge plates 74 are situated near and parallel to the balustrade position indicators 70. The depth gauge plates 74 include lower edges 76 that facilitate aligning a balustrade panel holder.

[0032] A method of using the device 40 includes situating the device 40 on one of the steps 22 as shown in Figure 4. The base 42 is received against or on the tread surface of a selected step 22 with the tabs 52 received against a front edge 80 of the step and the tabs 54 at least partially received in respectively corresponding grooves 82 on the tread surface of the step 22. In the illustrated example the width of the base 42 is approximately equal to a lateral spacing between skirt panels 84 on opposite sides of the steps, which further facilitates situating the device in a proper position on the selected step 22.

[0033] With the device 40 in the position shown in Figure 4 it is possible for a technician or mechanic to install components of the passenger conveyor, such as balustrade panel supporting components 90. As can be appreciated in Figure 5, the balustrade position indicators 70 are received in a channel 92 of the respective balustrade panel support 90. The plates of the balustrade position indicators 70 in this example have a thickness corresponding to a thickness of the balustrade panels 30 and the edges 72 facilitate accurately aligning the balustrade panel supports 90. The distance between the balustrade position indicators 70 establishes the finish or installed spacing between the balustrade panels 30 once installed.

[0034] In Figure 4 one set of balustrade panel supports 90 closer to the top of the illustration were installed when the device 40 was situated on the step 22 above the step 22 on which the device 40 is situated in the illustration. After those supports 90 were secured in place, the device 40 was removed from that step and placed on the step as illustrated to install the lower (according to the drawing) set of supports 90. The device 40 can be sequentially placed on a selected step 22, used to install selected components, removed from that step, and placed on another step to install or position additional conveyor components until the entire installation of such components is complete.

[0035] The example device 40 is also useful for installing or positioning outer deck components of the conveyor 20. Figures 6 and 7 show an example installation of outer decking clips 100. The frame members of the template 60, such as the beam 68 facilitate properly positioning and aligning outer decking clips 100 by accommodating such clips. In this example, the beam 68 has a width that corresponds to a channel or groove 102 on the decking clips 100 so that the decking clips 100 can be reliably positioned relative to the device 40 in a properly aligned installation position where the clips 100 are secured in place as part of the outer decking 104.

[0036] The device 40 shown in Figures 2 and 3 is useful for setting the balustrade and outer decking components, for example, along the incline section of the passenger conveyor 20. The device 40 shown in Figure 8 is useful for setting the balustrade and outer decking components along the ends of the passenger conveyor 20 near the landings 24 and 26. In this example, the supports 56' situate the template 60 at a different angle relative to the base 42 compared to the angle provided in Figures 2 and 3. In Figure 8, the template 60 and the base 42 are parallel to each other. The lower edges 72 of the balustrade position indicators 70 establish a position for the finish edge of the balustrade panels 30 near the landings 24, 26 that is parallel to the tread surfaces of the steps and the floor surfaces near the landings.

[0037] Devices designed according to an embodiment of this invention may be used to install or position other passenger conveyor components that are not illustrated or discussed above. Devices designed according to an embodiment of this invention facilitate faster, more efficient and more accurate placement of passenger conveyor components during installation or adjustment procedures.

[0038] The preceding description is exemplary rather than limiting in nature. Variations and modifications to the disclosed examples may become apparent to those skilled in the art that do not necessarily depart from the essence of this invention. The scope of legal protection given to this invention can only be determined by studying the following claims.
