Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
143 words
A physical exercising device comprising: an outer member having a handle portion; an inner member having a handle portion; a compression spring connected between the outer member and the inner member and in cooperative relation with the outer member and the inner member whereby the compression spring will be compressed when the outer member and inner member are caused to be moved with respect to each other; an intermediate member located between the outer member and the inner member which is of smaller cross section than the outer member and of larger cross section than the inner member; and said outer member having means which cooperate with the intermediate member and said inner member having means which cooperate with the intermediate member so that the outer member may slide over the intermediate member and the inner member may slide within the intermediate member.
Claim 2
Dependent Claim
