Edger Resurfacing Machine

Abstract

An edger machine for treating a floor and other surfaces has a housing with a motor and a deck. The motor has a drive shaft extending into an upper deck section of the deck. A pulley is positioned forward of the drive shaft, and a drive belt connects the drive shaft to the pulley. The pulley is constructed to mount a resurfacing disc in a lower deck section of the deck. A pair of guide wheels is mounted on an upper surface of the lower deck section adjacent the upper deck section. The guide wheels are rotatable about a vertical axis and positioned such that the wheels can roll against a vertical surface.

Description

TECHNICAL FIELD[0001]The field of this invention relates to edger resurfacing machines, for example, floor edger machines.BACKGROUND OF THE DISCLOSURE[0002]Floors and other planar surfaces have long been treated, prepared, polished and cleaned. Concrete floors are common today in large, medium and small retail stores, manufacturing and production facilities, warehouses, automotive shops and service centers, shopping centers, sidewalks, garages, commercial buildings and residential basements. The strength of concrete provides the durability and rigidity required in these environments. However, the exterior surface of a newly poured concrete floor, once dry, is often rough, uneven, and provides a dull appearance. Furthermore, when left in this unfinished state, the concrete will inherently produce dust particles from the constant scuffing, whether it is from foot traffic or wheeled traffic that can build over time and become a nuisance to those who work and / or live in these environmen...

AI Technical Summary

Benefits of technology

This patent is about an edger machine for treating floor and other surfaces. It includes a housing with a motor and a deck. The motor has a drive shaft and a pulley is positioned forward of the shaft. A drive belt connects the shaft to the pulley. The pulley is designed to mount a resurfacing disc in a lower deck section. The lower deck section is positioned below a front section of the deck and has a rear wall with a vacuum exit. The machine also has a main frame and travel wheels for moving between a stored position and a surface engaging position. Additionally, there is a castor frame assembly with a subframe pivotably and adjustable mounted thereto, and a castor wheel for adjusting the axis of rotation on a generally horizontal surface. The castor frame assembly is a first plate member and the subframe has a second plate member hinged to the first plate member, which can be adjusted with a turn screw to change the spacing between the plates. These features improve the performance of the edger machine and make it easier to use on various surfaces.

Problems solved by technology

However, the exterior surface of a newly poured concrete floor, once dry, is often rough, uneven, and provides a dull appearance.

Furthermore, when left in this unfinished state, the concrete will inherently produce dust particles from the constant scuffing, whether it is from foot traffic or wheeled traffic that can build over time and become a nuisance to those who work and / or live in these environments.

While walk along configurations and ride-on configurations have both been used, they both generally cannot be used to grind or sand close to an edge of the floor surface where a wall, molding or shelf stands extend vertically upward.

Presently known constructions for edger machines pose several problems.

This torque fatigues the operator and makes it harder for the operator to control the machine.

In addition, the exposed edge of the disc may engage and gouge the wall or side molding if the operator does not adequately control the machine.

Some of these machines are unable to reach under cabinets to reach “toe-kick” spaces.

Furthermore, some of these machines are hard to maneuver because of inadequate wheel control.
