Problems solved by technology

As such, many of us remember problems attendant with using the common blackboard eraser.
The common blackboard eraser typically is made from laminated felt pads attached to a cardboard backing board, and with its use, three problems arise.
A second problem is the construction of the eraser.
The felt pads and backing used to secure the felt pads are often too thin causing a user to hold the eraser by the sides of the felt pads in order to clean a blackboard.
Therefore, the user often gets chalk dust on his or her fingers just from using the eraser.
The third problem is that of ghosts.
Common chalkboard erasers do not clean

Embodiment Construction

[0021] Referring now to FIGS. 1 through 4, a first embodiment of the microfiber chalkboard eraser 10 is shown which includes a central core 11 (shown on FIG. 2), a finger cap or holder 12, and a microfiber fabric cleaning sheet 13. More specifically, the holder 12 has a rectangular shape with an open bottom (not shown). The holder 12 has a height sufficient to keep the user's fingers from the cleaning sheet 13 thereby avoiding chalk dust. The holder 12 may be made of plastic or other suitable materials. The central core 11 has a rectangular form and sized to fit within the holder 12, and in some aspects, retain the microfiber fabric cleaning sheet 13 on the central core 11 when the covered central core 11 is placed within the holder 12. The central core 11 preferrably may be made from of EPS (Expanded Polystyrene) foam or EPP (Expanded Polypropylene) foam.

[0022] The central core 11 is covered by the microfiber cleaning sheet 13. Microfibers are small fibers having a dimension of ab...

Abstract

The microfiber chalkboard eraser has a central core fully covered by a microfiber cleaning sheet with a finger holder cap covered on its top. The microfiber cleaning sheet cleans the chalkboard cleaner and reduces the air borne chalk dust compared to commonly used chalkboard erasers. The microfiber cleaning sheet has two sides that can be configured to form four cleaning surfaces, and can be washed or replaced when the two sides are soiled with chalk dust. Additionally, the finger holder cap can keep a user's hands free from chalk dust.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to chalkboard and marker board erasers, and specifically to a chalkboard and marker board eraser using microfiber material as a cleaning material. BACKGROUND OF THE INVENTION [0002] Blackboard erasers are a common item of everyday life. There are few among us who, as elementary school students, have not undertaken the chores of assisting a teacher in cleaning a blackboard or cleaning blackboard erasers by banging them together in the school yard. As such, many of us remember problems attendant with using the common blackboard eraser. [0003] The common blackboard eraser typically is made from laminated felt pads attached to a cardboard backing board, and with its use, three problems arise. The first is the chalk dust. The felt pads are normally made of nylon threads that do not hold much chalk dust, thereby chalk dust is released into the classrooms with use. A second problem is the construction of the eraser. The ...
