Abstract

Provided herein is a system that comprises re-chargeable batteries which enables a workman to use hand-held power implements having greatly reduced weight over systems of prior art. By minimizing the weight of the hand-held implement, stress on the users hand and wrist which are normally necessary to counterbalance gravitational forces acting on the implement are greatly diminished, thus dramatically reducing the propensity for a workman using such a system to develop carpal tunnel syndrome.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 ) A system for using a hand-held power implement which comprises 
 a) a belt means;    b) a pouch means;    c) a battery disposed in said pouch means, said battery having a positive pole and a negative pole;    d) a hand-held electrical implement having a DC-operated motor, wherein said motor comprises an armature that comprises a coil having a first end portion and a second end portion;    e) a first wire having a first end portion and a second end portion, wherein said first end portion of said first wire is attached to the positive pole of said battery and wherein said second end portion of said first wire is connected to the first end portion of said coil;    f) a second wire having a first end portion and a second end portion, wherein said first end portion of said second wire is attached to the negative pole of said battery and wherein said second end portion of said second wire is connected to the second end portion of said coil.    
     
     
         2 ) A system according to  claim 1  wherein the second wire includes a switch disposed between said negative pole and the second end portion of said coil.  
     
     
         3 ) A system according to  claim 1  wherein the first wire includes a switch disposed between said positive pole and the first end portion of said coil.  
     
     
         4 ) A system according to  claim 1  wherein said battery is a rechargeable battery selected from the group consisting of: nickel-cadmium, metal hydride, lithium, lithium ion, and rechargeable alkaline batteries.  
     
     
         5 ) A system according to  claim 1  further comprising: g) a self-retracting cord reel disposed between said battery and said hand-held implement and containing both of said first and said second wires.  
     
     
         6 ) A system according to  claim 5  further comprising: h) a holster means disposed on said belt.  
     
     
         7 ) A system according to  claim 1  further comprising: g) a holster means disposed on said belt.  
     
     
         8 ) A system according to  claim 1  wherein said drill includes a handle portion having a bottom portion, and further comprising a quick-disconnect electrical connector at said bottom portion.  
     
     
         9 ) A system according to  claim 1  wherein the poles of said battery are in electrical contact with a quick-disconnect electrical connector.  
     
     
         10 ) A system according to  claim 1  wherein said hand-held implement comprises a drill.  
     
     
         11 ) A system according to  claim 10  wherein the second wire includes a switch disposed between said negative pole and the second end portion of said coil.  
     
     
         12 ) A system according to  claim 10  wherein the first wire includes a switch disposed between said positive pole and the first end portion of said coil.  
     
     
         13 ) A system according to  claim 10  wherein said battery is a rechargeable battery selected from the group consisting of: nickel-cadmium, metal hydride, lithium, lithium ion, and rechargeable alkaline batteries.  
     
     
         14 ) A system according to  claim 10  further comprising: g) a self-retracting cord reel disposed between said battery and said hand-held implement and containing both of said first and said second wires.  
     
     
         15 ) A system according to  claim 14  further comprising: h) a holster means disposed on said belt.  
     
     
         16 ) A system according to  claim 10  further comprising: g) a holster means disposed on said belt.  
     
     
         17 ) A system according to  claim 10  wherein said drill includes a handle portion having a bottom portion, and further comprising a quick-disconnect electrical connector at said bottom portion.  
     
     
         18 ) A system according to  claim 10  wherein the poles of said battery are in electrical contact with a quick-disconnect electrical connector.
