## Background
BACKGROUND OF THE INVENTION
The present invention relates generally to the field of elevators and more specifically to an elevator cab interior protection system.
Elevators, for example, in buildings, may be high-traffic areas, with many people entering, riding in, and exiting the cabs of elevators. For many buildings, e.g., buildings with several floors, skyscrapers, etc., it may be highly inconvenient or impractical for elevators to be taken out of service to repair damage to the interior of the elevator cab. Therefore, interior protection systems may be installed into elevator cabs to protect the cab walls from damage. This may reduce time that elevator cabs need to be out of service to repair damage. Additionally, interiors of elevator cabs may be made to have an aesthetic look that matches other portions of the building.
SUMMARY OF THE INVENTION
One embodiment of the invention relates to an elevator cab protection system for an elevator cab having at least one wall. The system includes a first panel. The first panel extends a first height from a lower end to an upper end. The first panel extends a first width from a first end to a second end. The system includes a second panel. The second panel extends a second height from a lower end to an upper end. The second panel extends a second width from a first end to a second end. The system includes three clips each extending a third width from a first end to a second end. Each of the clips includes a lower leg portion, an upper leg portion, a lower throughbore, and an upper throughbore. The first clip is coupled to the first panel by a first fastener extending through the lower throughbore. The lower leg portion of the first clip and the first panel define a first downwardly opening slot. The second clip is coupled to the first panel by a second fastener with the upper leg portion of the second clip being located above the upper end of the first panel and being configured to define with the at least one wall of the elevator cab a first upwardly opening slot. The third clip is coupled to the second panel by a third fastener. The lower leg portion of the third clip is configured to be inserted into the first upwardly opening slot defined by the upper leg portion of the second clip and the at least one wall of the elevator cab to support the second panel relative to the first panel. The third width is less than the first width.
Another embodiment of the invention relates to a method of protecting the interior of an elevator cab located at a first location. The method includes coupling first and second clips to a first panel and a third clip to a second panel at a second location different than the first location of the elevator cab. The method includes fastening the second clip to a wall of the elevator cab. The wall of the elevator cab and the second clip form an upwardly opening slot. The method includes inserting a portion of the third clip into the upwardly opening slot thereby locating the second panel relative to the first panel.
Another embodiment of the invention relates to an elevator cab protection system for an elevator cab having at least one wall. The system includes a first clip coupled to a first panel by a first fastener. The panel has an upper peripheral edge.

DETAILED DESCRIPTION
Referring generally to the figures, various embodiments of an elevator cab interior protection system 100 are illustrated. The system 100 is configured to provide protection for the interior walls of an elevator cab. Additionally, the system 100 may be configured to change the appearance to the interior of the elevator cab, for example, an aesthetic that matches the aesthetic of other portions of the building in which the elevator cab is located. Additionally, the system 100 is configured to be installed onsite into an elevator cab. Therefore, in one embodiment, the system 100 is configured for ease of installation and to minimize or eliminate time-consuming steps that may be incorrectly completed, e.g., eliminating the need to measure the elevator cab onsite at the elevator cab location, eliminating the need to cut and drill at measured locations and to install supports at locations based on the measurements, eliminating the need to modify dimensions of supports for the system onsite at the cab location based on measurements of the cab, etc.
Referring to FIG. 1, an interior of an exemplary elevator cab is illustrated. An embodiment of an elevator cab interior protection system 100 is shown installed in the elevator cab protecting the walls of the elevator cab. The system 100 includes a plurality of panels 102 supported relative to the walls of the cab (not visible behind the panels 102 in FIG. 1). Located between the panels 102 are strips, e.g., extended width strips, metal or plastic, etc., shown as reveal strips 104. The reveal strips 104 are configured to protect the portions of the cab wall located between the panels 102. The elevator cab includes a floor 106 and a ceiling 108. Extending outwardly from the panels 102 between the floor 106 and the ceiling 108 are railings 110. Proximate the floor 106 of the elevator cab is a toe kick panel 112. In one embodiment, the panels 102 are configured to be installed sequentially upwardly from the toe kick panel 112 up, as will be further described below. In one embodiment, each of the panels 102 extends a width W1. In one embodiment, the width W1 of each of the panels 102 is the same. In other embodiments, the widths of different panels 102 may be different. In one embodiment, the width W1 is between 50 inches and 100 inches. In another embodiment, the width W1 is approximately 96 inches.
With reference to FIGS. 2 and 3, an embodiment of a clip 200 is illustrated. The clip 200 is configured to be coupled to an elevator cab wall and to locate and/or support a panel 102 of the elevator cab interior protection system 100 shown in FIG. 1.

The reveal retainer 418 is coupled to the wall 404 by a fastener shown as a screw 424. With reference to FIG. 29, the panel 414 overlies a portion of the vertical reveal 416. A horizontal reveal 426 installed, such as, for example, as described above, overlies a portion of the reveal retainer 418 and is located spaced apart from the wall 404 by the reveal retainer 418 to align with and abut the vertical reveal 416. A vertical reveal may be similarly (e.g., mirror image) installed in the corner between the second sidewall 406 and the second front wall 410.
With reference to FIG. 30, a pair of reveal retainers 428 and 430 support and locate vertical reveals 432 and 434 in the corner between the rear wall 402 and the first sidewall 404. The reveal retainers 428 and 430 are identical, e.g., substantially identical, to the reveal retainer 418 described above. The first reveal retainer 428 includes a flange 436 that is located flush against the wall 404 and spaces a second portion 438 of the reveal retainer 428 away from the wall 402. The vertical reveal 432 is coupled, e.g., by adhesive, tape, etc., to the second portion 428 on an opposite side from the wall 402. The reveal retainer 428 is coupled to the wall 402 by a fastener shown as a screw 440. The second reveal retainer 430 includes a flange 442 that abuts the second portion 438 of the reveal retainer 428 and spaces the second portion 444 of the reveal retainer 430 away from the wall 404. The vertical reveal 434 is coupled, e.g., by adhesive, tape, etc., to the second portion 444 on an opposite side from the wall 404. The vertical reveals 432 and 434 are thus positioned abutting one another and forming a corner. With reference to FIG. 31, the panels 414 each overlie a portion of one of the vertical reveals 432 and 434. Horizontal reveals 446 and 448 installed, such as, for example, as described above, overlie a portion of the reveal retainers 428 and 430 and are located spaced apart from the walls 402 and 404 by the reveal retainers 428 and 430 to align with and abut the vertical reveals 432 and 434. Vertical reveals may be similarly (e.g., mirror image) installed in the corner between the back wall 402 and the second sidewall 406.
In one embodiment, elevator cab interior protection systems such as those described may include panels with clips attached to the panels in predetermined locations, based on elevator cab dimensions, etc. The panels may be attached to clips at a physical location different than the location at which the system will be installed into the elevator cab, e.g., the panels and clips can be screwed together at a factory and then the panels may be hung in the elevator cab, with the clips not needing to be screwed to the panels at the elevator cab location. The lowest panel may be hung on a toe kick plate using a lower clip and a fastener may be inserted into an upper clip to attach the panel to the wall. The next lowest panel may then be hung with its lower clip interfacing with the upper clip of the lower panel. Thus, the elevator cab interior protection system may be installed without the need to drive a fastener through the panels, either to attach a clip to a panel or to attach a panel to the elevator cab wall, and, therefore, the system may be installed easily and with the installation system minimizing the opportunity for mistakes, e.g., mis-measuring, driving a fastener through a panel in an incorrect location, etc.
