## Background
FIELD OF INVENTION
The present invention relates to building construction and more particularly to an advantageous method of designing and constructing an attractive elevator cab at a reduced cost. This elevator cab design method reduces the burden, time commitment and cost of designing, manufacturing and installing a custom elevator cab.
BACKGROUND OF THE INVENTION
Traditional Methods of Cab Selection
Traditionally, there are three methods by which an elevator cab design is chosen. The method of selection is usually determined by the quality of the building: Rated from A down to C as illustrated below:
















“A”
“B”
“C” or

traditional designs


2)
“Make it look like that building”

40%
25%


3)

100%
20%









The first method of picking a stock or traditional elevator cab design is usually low cost because the materials are low quality and the engineering is simple. Unfortunately, these cabs are usually unattractive and do not enhance the appearance of the building in which they are installed. Integrated elevator companies that manufacture, install and service elevators, usually have very little incentive to make their cabs attractive by the use of high-quality and decorative materials because they are selling a complete elevator package, and the look of the cab has little influence on the buyer's decision when buying a complete package.
The primary advantage of the second method, to replicate another design, is that the look and cost will be fairly well known before the contract is put to bid. This does not mean that the buyer is getting good value, because if the original is a poorly designed cab, the copy will be no better and may be quite expensive.
The third method, creating a new design, may enhance the attractiveness of a building. However, most architecturally designed cabs are very expensive because the engineering for each one is largely customized and the buying power for material is low. In addition, lead times are very long because of the need for approvals of drawings and samples, plus the acquisition time for material and the time for making shop drawings.
SUMMARY OF THE INVENTION
Applicant proposes to change the way elevator cabs are designed by providing a series of elevator cab designs of high architectural quality that are made with premium, readily available materials and pre-engineered to reduce the cost and lead time.
Applicant's advantageous design method provides for selection of attractive and advantageous designs for elevator cabs for commercial, residential and institutional buildings. Applicant supplies engineering and manufacturing expertise to guide the architectural design decisions and material selection that minimize the material and labor costs that do not directly contribute to the appearance and structural integrity of the cab.
Applicant's method will also control the product cost by choosing from a material palette of high-end products such as glass, stone, wood and textured metals in a limited range. These materials have been selected for their attractive appearance, reasonable cost and ready availability. This will maximize the buying power for acquiring these materials at the lowest costs.
Building owners will save money by getting a product that costs as much as 25% less than cabs of similar materials and design would costs. They will be given the advantage of having a superior product in their buildings that will allow them to rent space more quickly and at higher prices.
With a limited palette of materials and photo-realistic renderings of interior elevator cab design, the time-consuming project management of coordinating drawings, samples and mockups between the owner, architect and cab maker are reduced dramatically. Standard pricing and industry discounts will lock in a profit margin that does not become reduced by unforeseen extras. The lead time for the cab can be eight weeks, with as much as a 40% cut, reducing the likelihood that overtime will be needed due to scheduling conflicts.
Architects and consultants usually loose money on the cab because of the technical complexity and lengthy approval process. Now an architect and designer will be able to select with confidence from world-class designs and elegant materials.
New Method Provides a New Financing Tool by an Operating Lease
In launching this product, Applicant has found creative ways to maximize the sales volume. One new area of interest is to change the transaction for the end user from a large lump-sum capital investment into an affordable and predictable expense. By offering these cabs through an operating lease, Applicant believes that there will be a three-fold benefit to the business:

    
    
        1. Expanding the base of potential customers by reducing the cost and making an attractive quality product available to building owners who lack the liquidity to pay for all this work at once.
        2. Increasing the market share within this base by providing a unique alternative that may present substantial savings to the customer.
        3. Raise the average selling price as customers trade up to more attractive designs and materials, because of the ability to spread the cost over time.
    
    


This invention discloses a method for drastically reducing the burden, time commitment and cost for designing, managing and installing a custom elevator cab. This method provides a way to upgrade the quality of the cab materials, design and craftsmanship and at the same time reduce the costs of an elevator cab by 33%. Real estate developers, building owners, architects, elevator companies and consultants can save time and money by ordering a custom elevator cab that could be viewed in advance and installed in only eight weeks.
The design method criteria takes into consideration the need for utilizing premium materials for the walls and ceiling without adding more than 300 pounds to the weight of the elevator cab. This method provides a solution for a cab that is 1) Innovative, 2) Custom made, 3) Time saving, 4) Easy to specify, 5) Easy to price, 6) Easy to install.
Material to be chosen include stone, wood, glass and woven wire mesh. These materials can be used in hundred of different combinations. Furthermore, using these materials allows you to complement any commercial, institutional or residential building's intrinsic design. Also, this method allows the incorporation of existing lobby materials or upgrades. This method provides affordability without compromising quality.
The cost of the average elevator cab using Applicant's design is 30% less compared to a custom design using the same material palette. This can equal a savings averaging $7,500 per cab. In addition, the design incorporates a lighter weight construction so that expensive elevator design modifications required by excess weight are eliminated.
This advantageous method of elevator cab design provides an attractive appearance complementary to a building in which the elevator is installed. The building is evaluated for determination of appropriate elevator cab interior design architecture and appearance. A suitable design is selected from a Series of previously prepared design proposal. Finally, material for the decoration of the cab interior is selected for the design from a palette of previously prepared options for available material including selection of material type, color and design. The Material Palette Option materials include wood, metal mesh, stone and glass and the material shown for selection from said palette include rectangular panel tiles. The material shown for selection from the palette for a decorative back rear panel includes a back wall panel which extends from floor to ceiling in height and extends to more than 1⁄3 of the width of the elevator. The remaining portion of the back rear wall of the cab is selected from rectangular panel tiles with decorative surfaces. The side walls of the cab are selected from said materials palette of rectangular panel tiles with decorative surfaces of the same design and color as the rectangular panel tiles on the back wall.
The method of elevator interior cab design includes providing the expertise of experienced designer for selecting a suitable design from a Series of design proposals for said building and providing the expertise of experienced designer for selecting the material for the decoration of the cab interior from a palette of options for available material type and color.
This method of elevator interior cab design provides expertise in elevator cab design architecture and elevator cab mechanical construction.

Example of Use of Series 300
Custom designed and constructed cab by world class architects exceeded budget and weight by 50% and lead time by an additional eight weeks. Working with the customer, the Applicant used the design method to incorporate the custom approved color palette into the Series 200 design. The new design was under budget and weight restrictions and within the required lead time. It took two weeks from the initial meeting for redesign and approval.
Sample of Use of 300 Series
Major institutional property owner had not hired architect to design the cab.
Problem
Wanted high quality cab completed in four months.
Solution
Working from the Applicant's design method catalog the customer found the appropriate design from the illustrations of FIGS. 7 and 8 that suited their building. In addition they picked out the metal, wood, stone and glass for the design from the Materials Palette Options. Within two weeks from the initial meeting a design was selected.
SAMPLE USE OF THE 400 SERIES DESIGN
Major institutional property owner sought to upgrade an unpleasant looking elevator interior.
Problem
Although approved, the initial design did not proceed due to budget constraints with the building.
Solution
Two years later, Applicant's method was introduced and a Series 400 design was selected. Material was selected from the Material palette. The original budget was lowered by $7,300 per cab
EXAMPLE
A building owner hired an 1,800-person architecture and interior design firm to do a visual modernization of the six passenger elevators in this prime Eastern large city property.
The architect's design was put out for bid. Applicant's bid, which was competitive, was for more than $30,000 per cab with a manufacturing lead time of 16 weeks. The design by the architect also added more than 500 pounds to the weight of the cab, which would require an expensive re-balancing of the counterweights by the elevator company.
Applicant than introduced the building owner to its design method using Designer Series 200 cab designs. Using the same primary materials and finishes as the architect, Applicant was able to provide a cab priced at less than $25,000, with a manufacturing lead time of 8 weeks while adding less than 300 pounds to the weight of the elevator cab, thereby avoiding a re-balancing. It took the owner and Applicant only one face-to-face meeting and less than two weeks to select and approve the interior design for the cabs.
EXAMPLE
In early September, a building owner of an upscale suburban office building decided to go ahead with a visual modernization of six passenger elevator cabs. However, they only had until the end of December to complete the entire project due to capital budget requirements. Normally, selecting an architect, designing the cabs and putting them out to bid would be a 3–4 month project. With the need for 14–16 weeks for an elevator cab company to submit drawings for approval, then manufacture and install the product, the building owner was out of time for such a traditional approach.
Applicant presented the building management with its design method using the Designer Series 200 cab designs. A half-day survey of the existing cabs determined that a Series 200 cab would fit without a problem The building management was able to select stock materials from the Applicant's material palette and get a quote and photo-quality rendering of their design within a week. The building owner approved the project within a week so that their cabs could be installed before the end of the year.
EXAMPLE
For more than three years, a building owner struggled to find an acceptable plan to visually modernize the 23 passenger elevators in a classic “cathedral of commerce” style building. The existing cabs were done in an unpleasant plastic laminate design that was entirely inappropriate. Despite a number of design attempts using both in-house and outside professionals, the building owner was unable to come up with a design that was architecturally attractive while still keeping the overall cost down. Applicant had worked with the building owner all along the way but only as a cab manufacturer and therefore could only provide reasons.
Finally, Applicant unveiled its design method to the building owner a design and its Designer Series 200 cab design to senior management of the building owner. In just two meetings, the building owner selected materials and approved the project at just over $20,000 per cab, well within the budget for this building.
