Abstract

The factors which influence the design of a lockset are carefully analyzed and the derived conclusions used as a set of requirements upon which to base the design

First, the architectural setting, door construction, and use of a door are studied to indicate the form which the lock should take. Then the buyers preferences, sales channels, and volume of sales are investigated to reveal sales features which should be incorporated in the design to insure its success on the market. These results are then used as a basis by which to determine performance requirements, production methods, suitable materials and construction.

The integration of all these factors results in the final solution of the design problem. The lockset is designed to be operated by pushing or pulling the handle and to be installed in a small V-notch in the door. The selected materials of construction make use of color in the form of anodized aluminum finishes as well as tinted plastics.

The operation and construction of the finished design is described in detail, and recommendations for its development as a commercial product are made.
