Claims
- 1. A portable apparatus for lifting, transporting and distributing a load, comprising:
- a. a horizontal frame support having parallel side rails connected by transverse supporting members;
- b. a first ladder shaped leg, having a pair of side rails connected by transverse supports and extending transversely away from said side rails of said horizontal support, thereby forming a base on said first leg being wider than said horizontal frame support, said first leg being, pivotally connected to a first end of said horizontal frame support and moveable between a first folded inoperative position and a second unfolded operative position, said first leg extending downwardly from said horizontal frame support when in said second operative position, said first leg including first and second telescopically mating members, whereby the length of said first leg is selectively adjustable;
- c. a second ladder shaped leg, having a pair of spaced parallel side members connected by transverse supports, and pivotally connected to the other end of said horizontal frame support and moveable between a first folded inoperative position and a second unfolded operative position, said second leg extending downwardly from and substantially perpendicular to said horizontal frame member when in said second operative position;
- d. means operatively connected to said first leg and said horizontal support for lifting and lowering a load, including a first pulley fixedly mounted on said horizontal frame member and a second pulley mounted on said horizontal frame member and moveable longitudinally therealong;
- e. means connected to said first leg for transporting said apparatus and said load;
- f. means for communication of said second leg with the ground, forming a support for lifting a load, said communication means comprising a generally ladder shaped bracket engageable with a ladder-like structure and said second leg, and being selectively adjustable in length whereby said load is distributed over both said first and second leg members and the ground when said first leg rests on a surface when is elevated with respect to the ground; and
- g. means for locking said first and second legs in said second unfolded operative position, further comprising:
- a. a pair of spring loaded latches extending through said side rails of said horizontal support;
- b. said first leg having apertures for receiving said latches;
- c. a pair of spring loaded latches extending through said side members of said second leg; and
- d. a pair of flanges connected to said side rails of said horizontal support having apertures therethrough for receiving said latches said portable apparatus in said first folded inoperative position is transportable on the back of a user.
- 2. The apparatus of claim 1, wherein said means for transporting said apparatus and said load comprises lockable wheels connected to said first leg.
- 3. The apparatus of claim 1, wherein said first leg further comprises:
- a. side rails having a longitudinal bore therethrough;
- b. a telescoping leg member slidably engaged within each of said bores and having vertically spaced and diametrically opposed apertures therethrough;
- c. snap latches connected to said side rails of said first leg extending into said bore for releasably mating with said apertures in said telescoping legs to lock said telescoping legs in an extended position; and
- d. a wheel rotatably mounted on each of said telescoping leg members.
- 4. The apparatus of claim 1, wherein said ladder shaped bracket for communication of said second leg with the ground comprises:
- a. a bracket attachable to a ladder and having:
- i. a pair of spaced parallel side rails having longitudinal bores therethrough for receiving said parallel side members of said second leg;
- ii. at least two transverse members connecting said said rails; and
- iii. snap latches associated with said side rails extending into said longitudinal bores; and
- b. said parallel side members of said second leg having a plurality of longitudinally spaced apertures for receiving said latches and locking said frame in engagement with said bracket.
- 5. The apparatus of claim 1, wherein said apparatus is constructed of lightweight metal.
- 6. The apparatus of claim 1, wherein said means for lifting and lowering a load further comprises:
- a. a winch connected to said first leg;
- b. said first pulley being mounted on said horizontal frame member near said first leg member; and
- c. a cable in driven engagement with said winch and said pulleys for connection to a load to be lifted.
