Range in probabilities of a fitted lrm model (Y~X)

Jan Verbesselt 
Dear R-list,

Is there a function or technique by which the probability (or log odds)
range of a logistic model (fit <- lrm(Y~X)) can be derived?

The aim is to obtain min & max of the estimated probabilities of Y.

Could summary.Design() be used for that or is there another method/trick?

Thanks,
Jan
