A device as in claim 1 characterized by said vertical support means including a vertically disposing portion of generally planar configuration the dependent extremity of which defines a ground contacting portion.
Claim 4
Dependent Claim
56 words
A device as set forth in claim 1 characterized by said vertical support means being peripherally convergent in an upward sense, from said dependent extremity which defines said ground contacting portion, vertical spaced portions thereof being provided with attachment means to dispose the said vertical support means outwardly of the pedal extremity of the adjacent leg.
Claim 5
Dependent Claim
46 words
A device as set forth in claim 1 characterized by said support means having a base of which inclines upwardly and outwardly from the dependent extremity of said support, to the side thereof which disposes outermost with respect to the leg to which it is applied.
