Abstract
Abstract A safety ladder foot is provided for stabilizing a side rail of a ladder and consists of a leg extending downwardly from side of a receptacle that receives bottom portion of the side rail. The leg has a beveled distal end to enter soft ground to prevent the side rail from slipping. A non-skid flat pad member has a chamber to receive the beveled distal end of the leg to prevent the side rail from slipping on a hard surface.

Total Claims: 5
Claim 1
Independent Claim
184 words
A safety ladder foot for stabilizing a side rail of a ladder which comprises: (a) a recepticle to receive bottom portion of said side rail; and (b) a leg extending downwardly from side of said receptacle, said leg having a beveled distal end to enter soft ground to prevent said side rail from slipping on said soft ground, further comprising a non-skid, flat pad member having a chamber to receive said beveled distal end of said leg to prevent said side rail from slipping on a hard surface, wherein said receptacle further has a top opening and a side opening opposite said leg being of equal size with width of said bottom portion of said side rail so that in one instance said receptacle can be positioned with said top opening to receive said bottom portion of said side rail to prevent said side rail from slipping on said soft ground and in another instance said receptacle can be positioned with said side opening to receive said bottom portion of said side rail to prevent said side rail from slipping on said hard surface.
Claim 2
Dependent Claim

A safety ladder foot for stabilizing a side rail of a ladder which comprises: (a) a recepticle to receive bottom portion of said side rail; and (b) a leg extending downwardly from side of said receptacle, said leg having a beveled distal end to enter soft ground to prevent said side rail from slipping on said soft ground, further comprising a non-skid, flat pad member having a chamber to receive said beveled distal end of said leg to prevent said side rail from slipping on a hard surface, wherein said receptacle further has a top opening and a side opening opposite said leg being of equal size with width of said bottom portion of said side rail so that in one instance said receptacle can be positioned with said top opening to receive said bottom portion of said side rail to prevent said side rail from slipping on said soft ground and in another instance said receptacle can be positioned with said side opening to receive said bottom portion of said side rail to prevent said side rail from slipping on said hard surface.
Claim 3
Dependent Claim
53 words
A safety ladder foot as recited in claim 1, further comprising: (a) said leg having a tongue slideably adjustable to said side of said receptacle having a groove so that said leg can be adjusted to any desired length; and (b) means for securing said leg within said track to any desired length.
Claim 4
Dependent Claim
84 words
A safety ladder foot as recited in claim 2, wherein said securing means includes: (a) a spring loaded locking pin mounted to within side of said receptacle adjacent to said leg; and (b) said leg having a plurality of spaced holes along one edge adjacent to said locking pin so that when said locking pin is pulled outwardly from said side of said receptacle said leg can be slideably adjusted to any desired length and then locked thereto when said locking pin is released.
Claim 5
Dependent Claim
100 words
A safety ladder foot as recited in claim 1, wherein said pad member further comprises: (a) a ball joint mounted to center of underside of said pad member; (b) a disc having a central socket on one side and a non-skid surface on other side, said socket receives said ball joint so that said disc can swivel in any direction; and (c) a pair of adjustment bolts, each of which is threaded through said pad member to properly adjust said disc to any desired angle so that said side rail can be prevented from slipping on a slanted hard surface.
