Hard ceiling tool

Abstract

A wire bending ceiling tool for cutting, bending and tying metal hanger wires such as those used for hanging false ceilings in buildings. The tool includes a pair of handles connected to a jaw having gripping members for holding a wire to be bent. One gripping member is a block to bend the wire around. The other gripping member is a surface to which a third handle is pivotally mounted. The third handle has a wire guide which guides the wire around three corners of the bending block to bend the wire into two right angles and a 45 degree angle when the third handle is pivoted creating a saddle to carry the channel beams, and which guides the wire around a corner of the bending block to bend the wire into one 90 degree angle when the third handle is pivoted creating a hook to attach to a main runner, an anchor or embed in concrete. The third handle detaches converting into a tying handle for tying a wire. The tying handle includes a wire guide operating in coordination with a hole for tying a hanger wire. Wire cutting edges located on the jaws cut a hanger wire when the gripping handles are squeezed together. Simultaneously pulling the third handle assists the wire cutting edges to cut the wire. The jaw hinge includes an indexed scale to determine proper bend location for the desired ceiling height.

1 . A wire bending device comprising: 
 (a) a pair of coordinating, pivotally mounted, elongated gripping handles operably connected to a pair of jaws with attached gripping members, said gripping members moving in response to movement of the gripping handles to grip a wire to be formed;    (b) one gripping member having at least three right angle corners with wire position locating flat facing portions extending therebetween, a first corner being at an outlet extending from between the gripping members and a second corner being proximately located from the first corner and spaced therefrom by a facing portion and a third corner being proximately located from the second corner and spaced therefrom by a facing portion; and    (c) a third coordinating bending handle pivotally mounted on the other gripping member by an axial connection means positioned on a line extending generally normally between the first and second and third corners, said bending handle having a wire guide extended therefrom at a point proximately located and generally equidistant to the first and second and third corners when the bending handle is pivoted whereby a pair of precisely spaced right angle bends with a straight portion therebetween and a third precisely spaced 45 degree bend with a straight portion therebetween may be formed in a wire at a selected position determined by the facing portions.    
   
   
       2 . A wire bending device as in  claim 1  wherein one gripping member preferably has a distance slightly greater than ½ inch between the first and second corner and has a distance slightly greater than 1½ inch between the second and third corner, although other sizes may be used as needed.  
   
   
       3 . A wire bending device as in claim one wherein the bending handle detaches to convert into a tying handle for tying a hanger wire.  
   
   
       4 . A wire bending device as in  claim 1  wherein the tying handle includes a wire tying hole for tying a hanger wire.  
   
   
       5 . A wire bending device as in  claim 1  wherein the tying handle includes a wire guide operating in coordination with a wire tying hole for tying a hanger wire.  
   
   
       6 . A wire bending device as in  claim 1  wherein the jaws include wire cutting edges to easily cut a hanger wire when the gripping handles are squeezed.  
   
   
       7 . A wire bending device as in  claim 1  wherein the bending handle coordinates with the wire cutting edges located on the jaws to easily cut a wire.  
   
   
       8 . A wire bending device as in  claim 1  wherein the jaw hinge includes an indexed scale to determine proper bend location in reference to a predetermined ceiling height.  
   
   
       9 . A wire bending device as in  claim 1  that bends a hook in a hanger wire to attach to a main runner, an anchor or embed in concrete.  
   
   
       10 . A wire bending device as in  claim 1  that ties a hanger wire to an anchor attached to the “true” ceiling.  
   
   
       11 . A wire bending device as in  claim 1  that bends a hanger wire to embed in concrete.  
   
   
       12 . A wire bending device as in  claim 1  that bends and ties a hanger wire to embed in concrete.  
   
   
       13 . A wire bending device as in  claim 1  wherein one gripping member preferably has a distance slightly greater than ½ inch between the first and second corner and has a distance slightly greater than 1½ inch between the second and third corner, although other sizes may be used as needed; wherein the bending handle detaches to convert into a tying handle for tying a hanger wire; wherein the tying handle includes a wire tying hole for tying a hanger wire; wherein the jaws include wire cutting edges to easily cut a hanger wire when the gripping handles are squeezed; wherein the bending handle coordinates with the wire cutting edges located on the jaws to easily cut a wire; wherein the jaw hinge includes an indexed scale to determine proper bend location in reference to a predetermined ceiling height; that bends a hook in a hanger wire to attach to an anchor or embed in concrete; and that ties a hanger wire to an anchor.
