Abstract:
1. A portable lift, comprising: a support base having a plurality of legs, wherein each of said plurality of legs respectively includes a distal portion and an inner portion; a plurality of adjustment members, each of said plurality of adjustment members extending downwardly from each of said distal portions of said plurality of legs respectively and configured to move vertically between a first position which is disengaged from a support surface and a second position which engages the support surface; a first lock member attached to said support base; a vertical mast extending upwardly from said support base; a support platform movably connected to said vertical mast, wherein said support platform is adapted to move upwardly and downwardly upon said vertical mast; and a second lock member attached to said support platform and adapted to mechanically connect to said first lock member; wherein said first lock member in combination with said second lock member form a pair of locking members which are configured to move between a locked state and an unlocked state, wherein said locked state locks said pair of locking members together which locks said support platform to said base and prevents said support platform from moving along said mast, wherein said unlocked state has said pair of locking members unlocked from one another to allow movement of said support platform vertically along said mast, wherein said pair of locking members is configured to switch from said locked state to said unlocked state as a direct result of at least one of said plurality of adjustment members moving from said first position to said second position which moves an engaging member along a major length of a corresponding one of said plurality of legs to unlock said pair of locking members from one another.
