The first layer and the second layer are at least partially overlapped and composited such that a plurality portions of the second panel member are recessed in a direction toward the first panel member to form a predetermined number of supporting structures distributed in a predetermined manner, wherein each of the supporting structures forms a recessed cavity therein and is at least partially fused with the first panel member.

Abstract: The present subject matter discloses an outdoor storage shed utilizing molded plastic components or panels. A storage shed structure can comprise foldable corner panels and one or more interlocked teeth couplings. The foldable corner panel can pivot at integrated folding grooves to serve as corners. The interlocked teeth couplings comprise a plurality of protrusions and matched recesses arranged on both sides of engaged panels. Furthermore, the storage shed can come with pre-constructed shelf grooves in the foldable corner panels. The storage shed can have a concaved door frame and a recessed door.

Abstract: A foldable picnic table with sitting benches is a table having a table plate and a number of table supports, and a plurality of benches having a bench body and a plurality of bench supports; wherein, each table support has an upper support and a lower support; the bottoms of each lower support and adjacent bench support are connected through a connecting piece; the table plate is capable of being lowered to the same height as the bench bodies when the upper supports and the lower supports are retracted relative to each other, the lower supports and the bench supports are folded to each other and turn over the bench bodies to the back of the table plate. Therefore, it is very convenient to fold, the size after folding is very small, and it saves transportation costs.

Abstract: An inner support panel includes a first partial panel, a second partial panel, a first layer, a second layer a first panel portion, a second panel portion, a first layer, a second layer, and at least one support structure. The first layer is stacked on the second layer. The first partial panel includes one or two combinations consisting of at least part of the first layer and at least part of the second layer. The second partial panel includes one or two combinations consisting of at least the other part of the first layer and at least the other part of the second layer. The first partial panel and the second partial panel are connected to each other and form a hollow structure by defining a cavity.
