Abstract

The present subject matter discloses an outdoor storage shed utilizing plastic components or panels. A storage shed structure can comprise foldable corner panels, which pivot at integrated folding grooves to serve as corners. Each leaf of a foldable corner panel can be fitted with a unique coupling mechanism to interact with an additional panel. Furthermore, the storage shed structure can come with pre-constructed shelf grooves in the foldable corner panels. Storage shelves can be slotted into these grooves, thereby boosting the overall stability of the storage shed.

Claims (44)

1 . A storage shed structure made of molded plastic panels, comprising:

a floor, the floor further comprises:

a plurality of corner edge floor panels; and

a plurality of transitional floor panels coupled to the plurality of corner edge floor panels via one or more connectors;

side walls coupled with the floor, the side walls further comprise:

a plurality of flat panels;

a plurality of foldable corner panels that form four corners of the storage shed structure, each foldable corner panel includes an embedded folding groove defined by a living hinge extending an entire length thereof, the embedded folding groove dividing each foldable corner panel into a first leaf and a second leaf;

one or more doors coupled with the side walls and the floor; and

a roof that comprises a plurality of foldable roof panels.

2 . The storage shed structure of claim 1 , wherein the embedded folding groove enables each foldable corner panel to fold at a fixed angle when the storage shed structure is installed.

3 . The storage shed structure of claim 1 , wherein the molded plastic panels comprise a number of back strengthening ribs that comprise vertical support grooves and horizontal support grooves, and wherein each vertical support groove is surrounded by a plurality of horizontal support grooves.

4 . The storage shed structure of claim 1 , wherein the plurality of transitional floor panels and the plurality of flat panels of the side walls are extendable.

5 . The storage shed structure of claim 1 , wherein the embedded folding groove is a first embedded folding groove and further comprising:

a second embedded folding groove positioned within each foldable corner panel.

6 . The storage shed structure of claim 1 , further comprising:

a number of back strengthening ribs that comprise vertical support grooves and horizontal support grooves, and wherein each vertical support groove is surrounded by a plurality of horizontal support grooves.

7 . The storage shed structure of claim 1 , wherein the plurality of foldable corner panels are connected to the plurality of flat panels via interlocked teeth couplings.

8 . The storage shed structure of claim 7 , wherein the interlocked teeth couplings comprise a plurality of protrusions and matched recesses arranged on both the plurality of foldable corner panels and the plurality of flat panels, wherein each of the corner panels and flat panels has a varied depth based on a design of the interlocked teeth couplings.

9 . The storage shed structure of claim 1 , further comprising:

a first coupling structure arranged on the first leaf;

a second coupling structure arranged on the second leaf, wherein the first coupling structure is different from the second coupling structure.

10 . The storage shed structure of claim 9 , wherein the first coupling structure comprises a slider and the second coupling structure comprises one or more clip slots.

11 . The storage shed structure of claim 1 , further comprising:

a plurality of shelf grooves embedded into interior surfaces of a respective foldable panel.

12 . The storage shed structure of claim 11 , further comprising:

one or more shelves configured to insert into the plurality of shelf grooves to provide storage and to enhance stability of the storage shed structure.

13 . The storage shed structure of claim 1 , wherein each corner edge floor panel has two sides to connect to wall panels and each transitional floor panel has one side to connect to the wall panels.

14 . The storage shed structure of claim 13 , wherein at least one side of the corner edge floor has more than one coupling mechanism.

15 . The storage shed structure of claim 13 , wherein a first side of a respective said transitional floor panel has a first slider rail, a first side of a respective said corner edge floor panel has a second slider rail configured to be in continuation with the first slider rail, and wherein the first side of the corner edge floor panel further has one or more clips.

16 . The storage shed structure of claim 13 , wherein the first slider rail of the respective transitional floor panel and the second slider rail of the respective corner edge floor panel are configured to engage with a first slider of a wall panel, and wherein the one or more clips of the respective corner edge floor panel are configured to engage one or more clip slots on the wall panel.

17 . A storage shed structure made of molded plastic panels, comprising:

a floor, the floor further comprises:

a plurality of corner edge floor panels; and

a plurality of transitional floor panels coupled to the plurality of corner edge floor panels via one or more connectors;

side walls coupled with the floor, the side walls further comprise:

a plurality of flat panels;

a plurality of foldable corner panels that form four corners of the storage shed structure, each foldable corner panel includes an embedded folding groove defined by a living hinge extending an entire length thereof, the embedded folding groove dividing each foldable corner panel into a first leaf and a second leaf;

a plurality of shelf grooves embedded into interior surfaces of the corner panels; and

one or more shelves configured to insert into the plurality of shelf grooves to provide storage and to enhance stability of the storage shed structure;

one or more doors coupled with the side walls and the floor; and

a roof that comprises a plurality of foldable roof panels.

18 . The storage shed structure of claim 17 , further comprising:

a number of back strengthening ribs that comprise vertical support grooves and horizontal support grooves, and wherein each vertical support groove is surrounded by a plurality of horizontal support grooves.

19 . The storage shed structure of claim 17 , wherein the plurality of transitional floor panels and the plurality of flat panels of the side walls are extendable.
