Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a portable toilet combination, and more particularly to a portable toilet combination including a foldable structure for allowing the portable toilet combination to be folded into a compact folding structure that is excellent for storing and transportation purposes.

2. Description of the Prior Art

Various kinds of typical portable toilet combinations have been developed and comprise a toilet seat for supporting a user, and a shelter or frame having a canvas covered on the outer peripheral portion thereof for enclosing or shielding the user and for forming an outdoor toilet.

For example, U.S. Pat. No. 6,378,142 to Gray discloses one of the typical foldable privacy screen and portable toilet combinations comprising a frame type covered in canvas around three sides of a folding frame supporting a toilet seat, and the frame folds flat and is provided with a handle for ease of carrying, storage and transport.

However, the folding frame is pivotally coupled to the toilet seat such that the folding frame and the toilet seat may not be easily separated from each other and may not be suitably folded into a compact folding structure. In addition, the partition frame also includes longitudinal rods or posts that also may not be suitably folded into a compact folding structure.

U.S. Pat. No. 6,718,565 to Cruz discloses one of the typical portable toilet shelters comprising a side wall structure supporting assembly for supporting the side wall structure upon a ground, and a frame attached to the roof member.

However, similarly, the side wall structure supporting assembly also includes longitudinal rods or posts that also may not be suitably folded into a compact folding structure.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional portable toilet combinations.
