Door Closure

Abstract

The door closure employs a pivotally mounted roller assembly to engage a roller within a recess of a mounting hook. The roller assembly also has a pair of leaf springs that are used in tandem to passively retain the bracket in each of the open position and the closed position.

What is claimed is: 
     
         1 . A door closure comprising
 a mounting hook defining a recess;   a longitudinally extending housing defining a cavity therein;   a bracket pivotally mounted within said cavity of said housing for movement between an open position and a closed position;   a roller mounted on one end of said bracket and projecting from said housing for movement into said recess of said mounting hook; and   at least one leaf spring secured in said housing and extending across said cavity, said leaf spring being in resilient contact with said bracket for selectively holding said bracket in each of said open position and said closed position.   
     
     
         2 . A door closure as set forth in  claim 1  further comprising a second roller rotatably mounted in said bracket and disposed in contact with said at least one leaf spring. 
     
     
         3 . A door closure as set forth in  claim 2  wherein said at least one leaf spring is arcuately disposed within said housing to accommodate rolling of said second roller thereon between said open position and said closed position. 
     
     
         4 . A door closure as set forth in  claim 1  further comprising a mounting bracket of flattened shape and wherein said housing is of U-shaped cross-section and is slidable mounted on said mounting bracket. 
     
     
         5 . A door closure as set forth in  claim 1  wherein said at least one leaf spring is of arcuate shape. 
     
     
         6 . A door closure as set forth in  claim 1  further comprising a second leaf spring disposed in contiguous contact with said at least one leaf spring. 
     
     
         7 . A roller assembly for a door closure comprising
 a longitudinally extending housing defining a cavity therein;   a bracket pivotally mounted within said cavity of said housing for movement between an open position and a closed position;   a roller mounted on one end of said bracket and projecting from said housing for movement into said recess of said mounting hook; and   at least one leaf spring secured in said housing and extending across said cavity, said leaf spring being in resilient contact with said bracket for selectively holding said bracket in each of said open position and said closed position.   
     
     
         8 . A roller assembly as set forth in  claim 7  wherein said housing is vertically disposed.
