Display device for article for sale

Abstract

A display device includes a plug device having a housing engageable into a hole of an article for sales, the housing includes a chamber and a spring blade having a projection to engage into a depression of the article, and for detachably attaching the housing to the article. A hanger device includes an actuator engageable into the chamber of the housing, to selectively engage with the spring blade of the housing, and to force and retain the projection of the spring blade within the depression of the article, and thus to detachably lock the housing to the article with the actuator of the hanger device. A locking device may be used to lock the actuator of the hanger device to the housing of the plug device.

1 . A display device for an article having a hole and a depression formed therein, said display device comprising: 
 a plug device including a housing engageable into the hole of the article, and said housing including a chamber formed therein, and including a spring blade provided therein, and including a projection extended therefrom and facing out of said housing, for engaging into the depression of the article, and for detachably attaching said housing to the article,    a hanger device including an actuator extended therefrom, and engageable into said chamber of said housing, to selectively engage with said spring blade of said housing, and to selectively force said projection of said spring blade within the depression of the article, and to detachably lock said housing to the article with said actuator of said hanger device, and    means for locking said actuator of said hanger device to said housing of said plug device.    
   
   
       2 . The display device as claimed in  claim 1 , wherein said housing includes a peripheral gap formed therein to form and to define said spring blade.  
   
   
       3 . The display device as claimed in  claim 1 , wherein said housing of said plug device includes a slot formed therein, said actuator of said hanger device includes a protuberance extended therefrom, and slidably engaged into said slot of said housing, to guide said actuator of said hanger device to slide relative to said housing of said plug device.  
   
   
       4 . The display device as claimed in  claim 3 , wherein said plug device includes a peg extended into said slot of said housing, and engageable with said protuberance of said actuator, to limit a sliding movement of said actuator of said hanger device relative to said housing of said plug device, and to prevent said actuator of said hanger device from being disengaged from said housing of said plug device.  
   
   
       5 . The display device as claimed in  claim 1 , wherein said locking means includes a latch extended from said plug device, to engage with said hanger device, and to lock said hanger device to said plug device.  
   
   
       6 . The display device as claimed in  claim 5 , wherein said hanger device includes a flap extended therefrom, and engageable with said latch of said plug device, to lock said actuator in said chamber of said plug device, and to prevent said actuator from sliding relative to said housing of said plug device.  
   
   
       7 . The display device as claimed in  claim 5 , wherein said plug device includes a peripheral recess formed therein, and formed around said latch, to increase a resilience of said latch.  
   
   
       8 . The display device as claimed in  claim 1 , wherein said plug device includes a plate secured on said housing, and engageable with the article, to allow said projection of said spring blade to be easily engaged into the depression of the article.
