Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
166 words
In a support for supporting and anchoring to the ground or other supporting surface a framework having a hollow tubular leg, subject to variable movements produced by fluctuating dynamic forces to which the framework is sometimes subjected, the combination comprising means for readily detachably connecting said support plate to said hollow leg, said means including a member having an outer cylindrical surface engaging the inner surface of said hollow leg when inserted therein, said member having a tongue depending outwardly from one end of said member and extending along the longitudinal axis of said cylindrical surface, and securing means connected to the support plate and freely rotaTable relative thereto and having a bifurcated portion pivotally connected to said depending tongue whereby the weight of the framework is supported by the support plate when said member is inserted into said leg and connection is maintained between said plate and the framework irrespective of said variable movements and/or variable angularity of said leg relative to the support plate.
Claim 2
Dependent Claim
166 words

Claim 3
Dependent Claim
23 words
Structure according to claim 1 and additionally including means including an opening in said plate for anchoring said plate to a supporting surface.
Claim 4
Dependent Claim
35 words
