Abstract
One embodiment of an adjustable dry wall sander comprises a handle (40), a pole (11), a portable, rechargeable electric power source (50) powering a vibrating eccentrically weighted electric motor (21) and interchangeable sanding head (30).
Description

- 1. Field of Invention
- The present invention generally relates to the field of power tools, and more particularly to a device for sanding drywall.
- 2. Prior Art
- Drywall panels assembled to cover walls are bonded together using a process by which tape applied to any holes and seams and then covered in joint compound embedding said tape and forming a unified sheet upon drying. Once dry any excess compound is then sanded smooth. Commonly hand sanding using poles or blocks is used. This method requires great stamina, and strength especially when working on large ceilings.
- On larger jobs heavy, corded, electrically powered rotational sanders are employed. These produce large amounts of dust due to their rotational disks and their high torque. These machines also require a great amount of strength and stamina as the machines are heavy and restricted by electrical cords. These electrical cords become a tripping hazard on many job sites. Additionally rotational drywall sanders have difficulties with the corner where a wall and ceiling meet and this area needs to be hand sanded. Rotary sander operators must frequently change positions as these sanders do not have the ability to have fully pivoting sanding heads.
- It would be desirable to provide a sander capable of being lightweight, which creates less dust than current motorized drywall sanders, and is free from cumbersome and potentially dangerous electrical cords.
- In accordance with one embodiment an adjustable dry wall sander comprises a handle, a pole, a portable, rechargeable electric power source powering a vibrating eccentrically weighted electric motor and interchangeable sanding head.

FIG. 1 (side view) andFIG. 2 (cutaway/detail view). The rechargeable electric power source connects to the handle theelectric motor 21 is mounted externally to the shaft of thepole 11 usingbolts 22 threaded through themounting block 25. Themounting block 25 is attached to theelectric motor 21 via a spot welded joint. Connected toelectric motor 21 is eccentrically mountedweight 24 composed of lead or other some other similarly heavy metal and connected via press fitting. Coveringelectric motor assembly 21 is the two halves ofplastic motor enclosure 20 attached topole 11 via screws. Sandinghead 30 is connected topole 11 at sandinghead screw mount 32 via a screw end onpole 11 fitting into sandinghead screw mount 32 onsanding head 30.Electric motor 21 is powered usingelectric wires 23 which are run throughpole 11 to handle 40 with one wire connected directly to the rechargeable electric power source and the other toactuator switch 42. - The manner of using the cordless drywall sander to sand drywall or gypsum board is identical to existing powered drywall sanders and is similar to existing manual sanding devices. Before use the
sanding head 30 must have sand paper attached to in a sufficiently fine grit. The rechargeableelectric power source 50 must also contain sufficient electrical charge to rotateelectric motor 21. By depressing actuator switch 42 andgrasping handle 40 in one hand andpole 11 in the other one can guide the position of thesanding head 30 on the drywall joint surface to smooth the joint. - From the above descriptions a number of advantages of some embodiments of my cordless drywall sander.
-
- a) The primary advantage of the cordless drywall sander is the cordless freedom of movement. This freedom of movement translates into a more professional finish of the drywall compound. Larger and more unwieldy machines have in the past been too cumbersome for finer detail work.
- b) Use of a square sanding head as opposed to the standard circular sanding head will allow the cordless drywall sander to reach into corners where other machines cannot go.
- c) Being cordless also means a safer tool as there is no longer an electrical power cord which can become a tripping hazard.
- d) By making the unit lighter than previous powered sanders the cordless drywall sander can be used on ceilings for longer periods without a break. This will help to reduce strain injuries.
- e) Versus the manual pole sander, the cordless drywall sander has the advantage that it reduces the effort of sanding considerably and will result in a reduction in the amount of time that it takes to complete sanding.
- Accordingly the reader will see that the cordless drywall sander can be used safely and efficiently to sand drywall compound with greater efficiency than using previous tools.
-
- It permits the ability to sand inside corners with it's square sanding head.
- It provides ease of use through it's light weight.
- It prevents injuries caused by tripping over electrical power cords.
- It significantly reduces the amount of time it takes to sand versus manual methods and tools.
- It provides for use of the tool in locations that do not have electrical power.
- The scope of this sanding tool should not be limited to sanding only drywall. It can be used to sand nearly any surface which requires a long reach without a long electrical power cord.
