Microfiber chalkboard eraser

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 ...

Benefits of technology

[0008] Objects of the invention are to provide a microfiber chalkboard eraser that can more completely clean the chalkboard, that can hold more chalk dust, that can remove chalk dust easier and faster, and that can clean the chalkboard more efficiently than the common chalkboard eraser.

[0009] Other objects of the invention include providing an easily replaceable cleaning surface that can be reused after being cleaned, and providing an eraser that has a finger cap or holder to keep the user's fingers free from chalk dust.

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 the chalkboard sufficiently; a significant quantity of chalk dust remains after using the common eraser, and the common eraser does not completely erase the writing but often leaves a significant image of the erased writing (a ghost image) that may interfere with new writing.

Other cleaning materials such as chamois and sponge can erase the blackboard cleaner than felt, but each alternate material has at least one disadvantage.

Sponge has a short life expectancy, and the cleaning efficiency of chamois decreases rapidly with use and chamois is difficult to clean.

However, none of these improvements were widely adopted.
