Angle bracket

Abstract

An angle bracket formed of a block of material. It has an elongated upper arm member formed adjacent the top end of a connecting member and an elongated lower arm member connected to the bottom end of the connecting member. The rear surface of the respective arm members make a 90 degree angle with each other. The top surface of the respective arm members have a swivel pad recess and a plurality of locking channels extend radially outwardly therefrom for receiving the arm of a clamp. An alternative embodiment angle bracket is capable of adjustable angles. It has an L-shaped upper clamp arm that is pivotally connected to an L-shaped lower clamp arm. Each of these arms have a V-shaped support clamp portion formed at their free end.

1 . An angle bracket for properly aligning structural members that will be rigidly connected to each other comprising: 
 a block of material having an elongated upper arm member, an elongated lower arm member and a connecting member;    said elongated upper arm member having a top end, a bottom end, a front surface, a rear surface, a left side edge and a right side edge;    said connecting member having an upper end, a lower end, a top surface, a bottom surface, a left side edge and a right side edge; said upper end of said connecting member being connected to said bottom end of said elongated upper arm member at an obtuse angle A;    said elongated lower arm member having a front end, a rear end, a top surface, a bottom surface, a left side edge and a right side edge; said rear end of said elongated lower arm member being connected to said lower end of said connecting member at an obtuse angle B;    first recess means on said front surface of said elongated upper arm member for removably receiving a swivel pad on an arm of a locking clamp; and    second recess means on said top surface of said elongated lower arm member for removably receiving a swivel pad on an arm of a locking clamp.    
     
     
         2 . An angle bracket as recited in  claim 1  wherein said block of material is made of metal.  
     
     
         3 . An angle bracket as recited in  claim 1  wherein said block of material is made of plastic.  
     
     
         4 . An angle bracket as recited in  claim 1  wherein said first and second recess means are generally circular recesses.  
     
     
         5 . An angle bracket as recited in  claim 1  further comprising a plurality of locking channels radiating outwardly from said first and second recess means for removably receiving an arm of a locking clamp.  
     
     
         6 . An angle bracket as recited in  claim 1  wherein said rear surface of said upper arm member is oriented at 90 degrees to said bottom surface of said lower arm member.  
     
     
         7 . An angle bracket as recited in  claim 1  further comprising an ear member extending laterally outwardly from one of said side edges of said respective elongated upper arm member and said elongated lower arm member; said ear members having a top surface and a bottom surface.  
     
     
         8 . An angle bracket as recited in  claim 8  further comprising an alignment pin extending rearwardly from said bottom surfaces of said ear members.  
     
     
         9 . An angle bracket as recited in  claim 1  further comprising a longitudinally extending groove in said rear surface of said elongated upper arm member and a longitudinally extending groove in said bottom surface of said elongated lower arm member.  
     
     
         10 . An angle bracket as recited in  claim 1  wherein said rear surface of said elongated upper arm member is substantially planar and said bottom surface of said elongated lower arm member is substantially planar.  
     
     
         11 . An angle bracket for properly aligning structural members that will be rigidly connected to each other comprising: 
 an L-shaped upper clamp arm having an upper leg portion oriented 90 degrees to a lower leg portion; said lower leg portion having a front end having a first cylindrical head; said upper leg portion having a top end having a V-shaped support clamp portion formed thereon;    an L-shaped lower arm having an upper leg portion oriented 90 degrees to a lower leg portion; said lower leg portion having a front end having a V-shaped clamp portion formed thereon; said upper leg portion having a top end having a second cylindrical tubular head; and    pivot means for pivotally securing said first and second tubular heads together so that L-shaped upper clamp arm and L-shaped lower clamp arm can be pivoted to respect to each other.    
     
     
         12 . An angle bracket as recited in  claim 11  further comprising means in said lower leg portion of said L-shaped lower clamp arm for adjustably seating and locking thereto a leg member of a sliding arm clamp.  
     
     
         13 . An angle bracket as recited in  claim 12  wherein V-shaped support clamp portion of said L-shaped lower clamp arm comprises a cross member having a left end and a right end; a left side support wing extends upwardly from said left end; a right side support wing member extends upwardly from said right end.  
     
     
         14 . An angle bracket as recited in  claim 13  wherein said right side support wing member has an outer end with a tab extending laterally therefrom; said tab having means for adjustably receiving and locking thereto a leg member of a sliding arm clamp.  
     
     
         15 . An angle bracket as recited in  claim 11  further comprising means in said upper leg portion of said L-shaped upper clamp arm for adjustably receiving and locking thereto a leg member of a sliding arm clamp.  
     
     
         16 . An angle bracket as recited in  claim 15  wherein said V-shaped support clamp portion of said L-shaped upper clamp arm comprises a cross member having a left end and a right end; a left side support wing extends upwardly from said left end; a right side support wing member extends upwardly from said right end.  
     
     
         17 . An angle bracket as recited in  claim 16  wherein said left side support wing member has an outer end with a tab extending laterally therefrom; said tab having means for adjustably receiving and locking thereto a leg member of a sliding arm clamp.
