  • Patent number: 6581894
    Abstract: A display device includes a housing for engaging into an article and having one or more projections formed in the outer peripheral portion for engaging into the article and for locking the housing to the article. A casing is secured on the housing. A hanger device has a block rotatably received in the casing, a board secured on the block, and an actuator attached to the block and engageable into the housing and rotatable force the projections to lock the block to the article. The board has an edge to be engaged into the casing and to be locked to the casing.

  • Publication number: 20020130235
    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.

  • Patent number: 6378700
    Abstract: A tool holding and displaying device includes two casings secured to a plate and each having a channel. A frame includes two panels engageable into the channels of the casings. The plate includes one or more catch members for engaging with the frame or with the panels of the frame and for securing or locking the frame to the plate. The frame may be used for receiving the tool and for solidly locking the tool to the plate and for preventing the tool from being easily disengaged from the plate and thus for preventing the tool from being obtained by any unauthorized person.
