Adjustable hanging device

Abstract

An adjustable hanging device, which hangs an object on a wall surface, includes a bracket, a screw rod, and a carriage. The bracket is mounted on the wall surface. The screw rod extends into the bracket, and is operable so as to rotate relative to the bracket. The carriage threadedly engages the screw rod, supports the object, and is movable along the screw rod when the screw rod is operated so as to adjust the position of the object on the wall surface.

1 . An adjustable hanging device adapted for hanging an object on a wall surface, comprising: 
 a bracket adapted to be mounted on the wall surface;    a screw rod extending into said bracket and operable so as to rotate relative to said bracket; and    a carriage threadedly engaging said screw rod, adapted to support the object, and movable along said screw rod when said screw rod is operated so as to adjust the position of the object on the wall surface.    
   
   
       2 . The adjustable hanging device as claimed in  claim 1 , wherein said bracket includes a first bracket part that defines therein a carriage-receiving space, said first bracket part including a top wall formed with a hole which is in spatial communication with said carriage-receiving space, 
 said carriage being disposed in said carriage-receiving space, and including a first carriage part formed with a first inner thread,    said screw rod having an enlarged head that is disposed externally of said carriage-receiving space and that is anchored to a periphery of said hole in said top wall of said first bracket part, and a shank that extends from said enlarged head of said screw rod through said hole and into said carriage-receiving space, said shank of said screw rod having a threaded portion that is separate from said first bracket part, and that engages threadedly said first inner thread of said first carriage part of said carriage.    
   
   
       3 . The adjustable hanging device as claimed in  claim 2 , wherein said shank of said screw rod further has a non-threaded portion disposed between said enlarged head and said threaded portion of said screw rod, and formed with an annular flange which projects radially therefrom, said enlarged head and said annular flange of said screw rod cooperatively defining an annular groove therebetween, said periphery of said hole in said top wall of said first bracket part being received in said annular groove.  
   
   
       4 . The adjustable hanging device as claimed in  claim 3 , wherein said carriage further includes 
 a second carriage part that extends transversely from said first carriage part in a direction away from said top wall of said first bracket part, and that is formed with a second inner thread, and    a threaded rod that engages threadedly said second inner thread of said second carriage part of said carriage and that is adapted to hang the object.    
   
   
       5 . The adjustable hanging device as claimed in  claim 4 , wherein said first bracket part defines an opening that is in spatial communication with said carriage-receiving space, said bracket further including a second bracket part for covering detachably said opening in said first bracket part, said second bracket part being formed with an elongated hole, said threaded rod extending outwardly of said carriage-receiving space through said elongated hole in said second bracket part, said elongated hole in said second bracket part having a sufficient length to permit movement of said threaded rod when said screw rod is operated.  
   
   
       6 . A hangable module comprising: 
 an adjustable hanging device including 
 a bracket adapted to be mounted on the wall surface,  
 a screw rod extending into said bracket and operable so as to rotate relative to said bracket, and  
 a carriage threadedly engaging said screw rod, and movable along said screw rod when said screw rod is operated; and  
   an object supported by said carriage so as to be adjustable in position on the wall surface.    
   
   
       7 . The hangable module as claimed in  claim 6 , wherein said bracket includes a first bracket part that defines therein a carriage-receiving space, said first bracket part including a top wall formed with a hole which is in spatial communication with said carriage-receiving space, 
 said carriage being disposed in said carriage-receiving space, and including a first carriage part formed with a first inner thread,    said screw rod having an enlarged head that is disposed externally of said carriage-receiving space and that is anchored to a periphery of said hole in said top wall of said first bracket part, and a shank that extends from said enlarged head of said screw rod through said hole and into said carriage-receiving space, said shank of said screw rod having a threaded portion that is disposed in said carriage-receiving space, that is separate from said first bracket part, and that engages said first inner thread of said first carriage part of said carriage.    
   
   
       8 . The hangable module as claimed in  claim 7 , wherein said shank of said screw rod further has a non-threaded portion disposed between said enlarged head and said threaded portion of said screw rod, and formed with an annular flange which projects radially therefrom, said enlarged head and said annular flange of said screw rod cooperatively defining an annular groove therebetween, said periphery of said hole in said top wall of said first bracket part being received in said annular groove.  
   
   
       9 . The hangable module as claimed in  claim 8 , wherein said carriage further includes 
 a second carriage part that extends transversely and downwardly from said first carriage part, and that is formed with a second inner thread, and    a threaded rod that engages threadedly said second inner thread of said second carriage part of said carriage to hang said object.    
   
   
       10 . The hangable module as claimed in  claim 9 , wherein said first bracket part of said bracket defines an opening that is in spatial communication with said carriage-receiving space, said bracket further including a second bracket part for covering detachably said opening in said first bracket part, said second bracket part being formed with an elongated hole, said threaded rod extending outwardly of said carriage-receiving space and through said elongated hole in said second bracket part, said elongated hole in said second bracket part having a sufficient length to permit movement of said threaded rod when said screw rod is operated.  
   
   
       11 . The hangable module as claimed in  claim 6 , wherein said object is a flat panel display.
