ABSTRACT:
The combined shock absorbing seat post and air pump assembly is for use on a bicycle or the like. The assembly comprises two hollow tubes inserted one into the other defining a compression chamber from which the compressed air may be sent to an inflatable device such as a tire. A shock absorbing mechanism is further provided for attenuating jarring conditions while operating the bicycle on a rough surface. The shock absorbing mechanism comprises an helicoidal compression spring in which the tension can be adjusted by hand upon rotation of a screwed element. The assembly provides a very practical and very compact assembly that combines the advantages of an air pump in the seat post and the advantages of an easily adjustable shock absorber mounted on the seat post.
