Abstract

Revised Invention Summary 9/03/2016: The invented whiteboard eraser holder consists of two main parts: the handle and the eraser holder. The handle is made from two 90-degree bent PVC pipes, two straight PVC pipes, and two perforated cylindrical wooden pieces assembled together. The eraser holder is made from one pre-fabricated aluminum sheet with two holes drilled in it. The two main components are assembled together using screws to secure them tightly. The whiteboard eraser is then inserted into the handle, pushing it all the way in to prevent movement or detachment while erasing the whiteboard. ------------------------------------------------------------- New Request (Revised 5/9/2016): The invented whiteboard eraser holder consists of two main parts: the handle and the eraser holder. The handle part consists of two 90-degree bent PVC pipes, two straight PVC pipe connectors, and two perforated cylindrical wooden pieces assembled together. The eraser holder is made from a pre-fabricated aluminum sheet with two holes drilled in it. The two main components are assembled together using screws to secure them tightly. The eraser is then inserted into the handle, ensuring it is fully seated to the edge to prevent movement or detachment while erasing the whiteboard.

Claims (2)

Updated 9/03/2016 1. The whiteboard eraser holder consists of two parts: the handle part (7) and the eraser holder part (5). The handle part is made of two 90-degree PVC pipes with a diameter of 22 mm (1), one 70 mm long PVC straight pipe with a diameter of 16 mm (2), and one 14 mm long PVC straight pipe with a diameter of 22 mm (3). They are assembled together using glue applied around the inside. Then, two cylindrical wooden pieces with a height of 20 mm and a diameter of 21 mm (4) are drilled with holes in the center and assembled with the 90-degree PVC pipe (7) using glue as well. Then, a pre-made aluminum sheet 130 mm long (5) is drilled with two holes (8) and two self-tapping screws (6) are used to firmly attach it to the cylindrical wooden pieces. The whiteboard eraser is then inserted into the whiteboard eraser holder (10). 2. The handle of the whiteboard eraser according to claim 1 has a unique characteristic: one end of the aluminum sheet is folded into a single edge (9) to prevent the eraser from falling out, and the handle is made of PVC pipe (7) because it will be lightweight and easy to hold. ------------------------------------------------------------------ New Request, Updated 5/9/2016 Whiteboard Eraser Holder consists of two parts: the handle and the eraser holder. The handle part consists of: 2 pieces of 90-degree bent PVC pipe, 22 mm in diameter; 1 piece of 70 mm long, 16 mm in diameter PVC straight pipe; 1 piece of 14 mm long, 22 mm in diameter PVC straight connector pipe; 2 pieces of cylindrical wooden rod, 20 mm high, 21 mm in diameter, with a hole in the center; 2 pieces of pre-fabricated aluminum plate, 130 mm long, with 2 holes drilled in the center; and 2 screws. The back of the aluminum plate must be folded and bent to fit snugly against the edge so that the eraser is securely attached to the handle and does not move.
