Display device for article for sale

Abstract

A display device includes an article, a housing for engaging into the article and having one or more projections for engaging with the article and for locking the article to the housing, and an actuator rotatably engaged in the housing and rotatable to align with the projections for forcing the projections to engage with the article, and rotatable away from the projections for allowing the projections to be disengaged from the article. A device may lock the actuator to the housing when the actuator is aligned with the projections.

I claim:

         2 . The display device according to  claim 1 , wherein said housing includes means for limiting a rotational movement between said actuator and said housing.  
     
     
         3 . The display device according to  claim 2 , wherein said limiting means includes at least one stop extended from said housing and extended inward of said chamber of said housing, for engaging with said actuator, and for limiting the rotational movement between said actuator and said housing.  
     
     
         4 . The display device according to  claim 3 , wherein said at least one stop is arranged to engage with said actuator when said actuator is aligned with said at least one projection.  
     
     
         5 . The display device according to  claim 1 , wherein said housing includes a partition having a slot formed therein, said actuator is engaged into said chamber of said housing via said slot of said partition of said housing.  
     
     
         6 . The display device according to  claim 5 , wherein said housing includes an orifice formed in said partition and communicating with said slot of said partition, said actuator includes a neck secured thereto and rotatably received in said orifice of said partition.  
     
     
         7 . The display device according to  claim 5  further comprising a board attached to said actuator for hanging purposes.  
     
     
         8 . The display device according to  claim 5  further comprising means for disengaging said actuator from said slot of said partition.  
     
     
         9 . The display device according to  claim 8 , wherein said disengaging means includes a protrusion extended in said housing, said actuator is engaged with said protrusion when said actuator is engaged into said chamber of said housing via said slot of said partition of said housing.  
     
     
         10 . The display device according to  claim 1  further comprising means for locking said actuator to said housing when said actuator is aligned with said at least one projection.  
     
     
         11 . The display device according to  claim 10 , wherein said locking means includes a casing secured to said housing and having a catch provided therein, a block secured to said actuator and having a latch for engaging with said catch and for locking said block and thus said actuator to said housing.  
     
     
         12 . The display device according to  claim 11 , wherein said housing includes a partition provided between said housing and said casing and having a slot formed therein, said actuator is engaged into said chamber of said housing via said slot of said partition of said housing.  
     
     
         13 . The display device according to  claim 12 , wherein said housing includes an orifice formed in said partition and communicating with said slot of said partition, said actuator includes a neck secured between said actuator and said block, and rotatably received in said orifice of said partition.  
     
     
         14 . The display device according to  claim 11 , wherein said casing includes an opening formed therein for receiving said block, and includes a recess formed therein for forming a bar in said casing, said latch is extended from said bar and extended inward of said opening of said casing.  
     
     
         15 . The display device according to  claim 11 , wherein said casing includes an opening formed therein for receiving said block, and includes at least one notch formed therein for forming a bar in said casing, said latch is extended from said bar and extended inward of said opening of said casing.
