It's very possible that you have a vining, pole-type, late-maturing beans. Otherwise they would be growing as short plants (bush-type beans) and would be producing beans.
Try some of the following bush-type beans and you will be pleased with the results: Blue Lake (be sure it is the bush-bean type and not the pole bean variety); Contender; Straight 'N Narrow, a French filet shoestring-type bean served in many gourmet restaurants; Greencrop; Filet Bean Triumph de Farcy; Fordhook Standard; and finally, a bean fit for aristocrats, Filet Bean La France.
