Adjustable shelf assembly

1. An adjustable shelf assembly comprising:

an elongated frame having a first end and a second end, the frame generally extending in a first plane; and

a first shelf attached to the frame by a first fastening element and a second shelf attached to the frame by a second fastening element, the entirety of each of the first and second fastening elements being positioned between respective first and second pairs of vertical bars of the frame, at least a portion of the first and second shelves extending in a second plane generally perpendicular to the first plane, the first and second fastening elements being fixedly attached to the frame such that lateral movement of the first and second fastening elements in the second, plane is prohibited, the first and second shelves being separately transversely movable in the second plane relative to the frame, wherein

the shelf assembly is in an open position when the first and second shelves are transversely moved away and spaced apart from each other in the second plane, a generally vacant space being formed between the first and second shelves, and

the shelf assembly is in a closed position when the first and second shelves are positioned proximate to each other.

2. The adjustable shelf assembly of claim 1 , wherein the first and second shelves contact each other in the closed position of the assembly.

3. The adjustable shelf assembly of claim 1 , further comprising a third and a fourth shelf attached to the frame, at least a portion of the third and fourth shelves extending in a third plane generally parallel to and spaced beneath the second plane of the first and second shelves, the third and fourth shelves being separately transversely movable in the third plane relative to the frame, wherein the third and fourth shelves are transversely moved away and spaced apart from each other in the third plane in the open position of the shelf assembly, a generally vacant space being formed between the third and fourth shelves, and wherein the third and fourth shelves are positioned proximate each other in the closed position of the shelf assembly.

4. The adjustable shelf assembly of claim 1 , wherein the first and second fastening elements are stationary relative to the frame and the first and second shelves are separately movable relative to the first and second fastening elements.

5. The adjustable shelf assembly of claim 4 , wherein the first and second fastening elements are brackets.

6. The adjustable shelf assembly of claim 1 , wherein each shelf includes a horizontally-oriented support member for supporting an article, the horizontally-oriented support member comprising a plurality of spaced apart horizontal bars.

7. The adjustable shelf assembly of claim 1 , further comprising at least one securing member attached to the frame for detachably securing the adjustable shelf assembly to a separate structure.

8. The adjustable shelf assembly of claim 7 , wherein the at least one securing member comprises a suction cup for detachably securing the adjustable shelf assembly to a wall.

9. An adjustable shelf assembly comprising:

an elongated frame having a first end and a second end, the frame generally extending in a first plane;

a first shelf member and a second shelf member attached to the frame, at least a portion of the first and second shelf members extending in a second plane generally perpendicular to the first plane, the first and second shelf members being separately transversely movable in the second plane relative to the frame; and

a first fastening element attaching the first shelf member to the frame, the first fastening element being stationary relative to the frame and being fixedly attached to the frame such that lateral movement of the first fastening element in the second plane is prohibited, the first shelf member being movable relative to the first fastening element, the first fastening element including a closed cylindrical channel which completely surrounds a periphery of at least a portion of the first shelf member,

wherein the first and second shelf members are in a first position when situated adjacent to each other, such that the first and second shelf members form a single shelf, and

wherein the first and second shelf members are in a second position when transversely moved away from each other in the second plane, such that the first and second shelf members form first and second separate and spaced apart shelves, a generally vacant space being formed between the first and second shelves and being configured to support a flexible tube of a shower head assembly.
