Abstract
Abstract A system for carrying construction materials for construction of a multi-level building includes an elongated stackable container having two identical separable sections spliced together in use, pairs of male and female coupling members adapted for engagement with complementary coupling members on adjacent like containers to facilitate stacking thereof, and retaining members for further limiting movement of the containers in a stack of containers with respect to one another. A support base having like coupling members and retaining members is also provided to accommodate several stacks of containers thereon for storage or transportation. Guide shoes having C-shaped guide bearing collars may be detachably mounted on the container for cooperation respectively with vertical guide rails spaced from the associated building, positively to guide the container during raising and lowering thereof by standard hoist means which is positioned to exert on the container a horizontal force component directed toward the building to urge the guide collars into engagement with the guide rails.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
350 words
Apparatus for carrying construction materials to and about a construction site, said apparatus comprising a support base, a plurality of base coupling members carried by said support base adjacent to the opposite ends thereof, a plurality of first retaining members carried by said support base intermediate the ends thereof, and a plurality of containers disposable in a stacked configuration substantially in vertical alignment upon said support base, each of said containers including a receptacle for accommodating construction materials therein and two coupling structures and two second retaining members, said coupling structures being respectively carried by said receptacle adjacent the opposite ends thereof, said second retaining members being respectively disposed adjacent to the opposite sides of said receptacle intermediate the ends thereof for engagement with an adjacent container when said containers are disposed in the stacked configuration thereof, each of said coupling structures including an upper coupling member identical to one of said base coupling members and a lower coupling member complementary to said first coupling members and said base coupling members for coupling engagement therewith when said containers are disposed in the stacked configuration thereof, said containers in the stacked configuration thereof having said lower coupling members on the bottom container respectively disposed in coupling engagement with corresponding ones of said base coupling members and having said upper coupling members on each container respectively disposed in coupling engagement on each container respectively disposed in coupling engagement with said lower coupling members of the immediately overlying containers thereby to prevent longitudinal displacement of said containers with respect to one another and with respect to said support base, said containers in the stacked configuration thereof having the bottom container disposed in engagement with said first retaining members and having said second retaining members of each container disposed in engagement with the immediately overlying container thereby to prevent lateral displacement and deflection of said containers with respect to one another and with respect to said support base, whereby said coupling members and said retaining members cooperate to prevent accidental unstacking of said containers by horizontal forces while accommodating vertical unstacking of said containers.
Claim 2
Dependent Claim
350 words
Apparatus for carrying construction materials to and about a construction site, said apparatus comprising a support base, a plurality of base coupling members carried by said support base adjacent to the opposite ends thereof, a plurality of first retaining members carried by said support base intermediate the ends thereof, and a plurality of containers disposable in a stacked configuration substantially in vertical alignment upon said support base, each of said containers including a receptacle for accommodating construction materials therein and two coupling structures and two second retaining members, said coupling structures being respectively carried by said receptacle adjacent the opposite ends thereof, said second retaining members being respectively disposed adjacent to the opposite sides of said receptacle intermediate the ends thereof for engagement with an adjacent container when said containers are disposed in the stacked configuration thereof, each of said coupling structures including an upper coupling member identical to one of said base coupling members and a lower coupling member complementary to said first coupling members and said base coupling members for coupling engagement therewith when said containers are disposed in the stacked configuration thereof, said containers in the stacked configuration thereof having said lower coupling members on the bottom container respectively disposed in coupling engagement with corresponding ones of said base coupling members and having said upper coupling members on each container respectively disposed in coupling engagement on each container respectively disposed in coupling engagement with said lower coupling members of the immediately overlying containers thereby to prevent longitudinal displacement of said containers with respect to one another and with respect to said support base, said containers in the stacked configuration thereof having the bottom container disposed in engagement with said first retaining members and having said second retaining members of each container disposed in engagement with the immediately overlying container thereby to prevent lateral displacement and deflection of said containers with respect to one another and with respect to said support base, whereby said coupling members and said retaining members cooperate to prevent accidental unstacking of said containers by horizontal forces while accommodating vertical unstacking of said containers.
Claim 3
Dependent Claim
143 words
The apparatus set forth in claim 1, wherein each of said receptacles has a box-like configuration substantially rectangular in transverse cross section and including four longitudinally extending side rails respectively defining the four corners of the rectangle, said second retaining members being connected to the upper ones of said side rails along the inner surfaces thereof and projecting upwardly therefrom, said first retaining members being positioned on said base for engagement with the outer surfaces of the lower side rails of the bottom one of said containers for preventing lateral movement of said containers in the stacked configuration thereof with respect to said support base, said second retaining members being positioned for engagement with the inner surfaces of the lower side rails of the immediately overlying container to prevent lateral movement of containers with respect to one another in the stacked configuratiOn thereof.
Claim 4
Dependent Claim
24 words
The apparatus set forth in claim 1, wherein said support base is mounted on a vehicle for transportation of a stack of said containers.
Claim 5
Dependent Claim
27 words
The apparatus set forth in claim 1, wherein said support base is shaped and dimensioned to accommodate thereon a plurality of stacks of said containers arranged side-by-side.
Claim 6
Dependent Claim
178 words
A container for carrying construction materials to and about a construction site and adapted to be coupled to associated like containers upon a support base to form a stack of containers, said associated like containers including an overlying container and an underlying container, said container comprising a receptacle for accommodating construction materials therein and including two coupling structures and two retaining members, said coupling structures being respectively carried by said receptacle adjacent the opposite ends thereof, said retaining members being respectively disposed adjacent to the opposite sides of said receptacle intermediate the ends thereof for engagement with said overlying container when said containers are disposed in the stacked configuration thereof, said coupling structures including upper coupling members and lower coupling members, said upper coupling members being complementary to lower coupling members of said overlying container and said lower coupling members being complementary to upper coupling members of said underlying container for coupling engagement therewith when said containers are disposed in the stacked configuration thereof to prevent longitudinal and lateral displacement of said containers with respect to one another.
Claim 7
