The article 20 includes a cavity 21 and one or more depressions 22 formed therein and communicating with each other.
The display device further includes a [0030] plug device 3 having a housing 31 to be engaged into the cavity 21 of the article 20. The housing 31 includes a noncircular cross section, and includes a chamber 39 formed therein for forming or defining a peripheral wall 38, and includes one or more projections 32 extended laterally outward from the peripheral wall 38 and having a semi-spherical structure, and includes one or more grooves 313 formed in the outer peripheral portion of the peripheral wall 38 for increasing the resilience of the peripheral wall 38 and for allowing the projections 32 to be engaged into the depressions 22 of the article 20 (FIGS. 7, 8).
A [0031] casing 33 is formed or provided or disposed or secured on top of the housing 31 and includes an opening 330 formed therein, and includes a recess 370 (FIGS. 3, 4) and one or more notches 372 (FIG. 2) formed therein and communicating with the opening 330 of the casing 33, for forming or defining a bar 371 in the outer peripheral portion of the casing 33. As best shown in FIGS. 3, 4, a tooth or a catch 37 is extended from the bar 371 and extended inward of the recess 370 and the opening 330 of the casing 33.
A [0032] partition 34 is formed or provided between the housing 31 and the casing 33, and includes a slot 35 and an orifice 36 formed therein and communicating with each other. The slot 35 of the partition 34 is diagonal or is formed diagonally relative to the housing 31, and includes a width smaller than the diameter of the orifice 36 of the partition 34. A pair of opposite stops 311 and a protrusion 310 are extended inward of the chamber 39 of the housing 31 from the peripheral wall 38.
A [0033] hanger device 4 includes a board 41 for hanging onto the supporting walls or the like, and includes a block 43 secured to the lower portion of the board 41, and an actuator 44 secured to the block 43 with a neck 42. The actuator 44 includes a width equals to or smaller than that of the slot 35 of the partition 34, for allowing the actuator 44 to be engaged through the slot 35 and to be engaged into the chamber 39 of the housing 31 (FIGS. 3, 4).
The [0034] neck 42 includes a circular cross section and includes a diameter equals to or smaller than that of the orifice 36 of the partition 34, for allowing the neck 42 to be rotatably secured to the plug device 3. The neck 42 includes a thickness no less than that of the thickness of the partition 34, for allowing the partition 34 to be engaged into the gap 46 that is formed between the block 43 and the actuator 44 (FIGS. 2, 7, 8), and for allowing the actuator 44 to be rotated relative to the housing 31 (FIGS. 4, 6) after the actuator 44 has been engaged into the chamber 39 of the housing 31. The plug device 3 and the hanger device 4 may thus be locked together after the actuator 44 is rotated relative to the housing 31.
In operation, as shown in FIGS. [0035] 5-8, when the actuator 44 is rotated to engage its ends or sides 441 with the peripheral wall 38, the projections 32 may be forced into the depressions 22 of the article 20 (FIGS. 7, 8), for locking the article 20 to the housing 31 of the plug device 3. Either or both of the stops 311 may engage with the sides 441 of the actuator 44 for limiting the rotational movement of the actuator 44 relative to the housing 31, and for retaining the alignment of the actuator 44 with the projections 32, and for preventing the projections 32 from being disengaged from the depressions 22 of the article 20.
As shown in FIGS. 2 and 5, the [0036] sides 441 of the actuator 44 are rounded, for allowing the actuator 44 to be engaged or moved over the protrusion 310 when the actuator 44 is engaged into the chamber 39 of the housing 31. The actuator 44 is preferably made of a material having a suitable resilience for allowing the actuator 44 to be slightly bent or twisted while moving over the protrusion 310. After moving over the protrusion 310, the actuator 44 will be disengaged from or will be prevented from being aligned with the slot 35 of the partition 34, such that the actuator 44 may be prevented from moving through the slot 35 of the partition 34 and may be prevented from being disengaged from the housing 31 of the plug device 3.
As shown in FIGS. [0037] 2-4, the block 43 includes a latch 45 formed or provided on the outer peripheral portion thereof for engaging with the catch 37 and for locking the hanger device 4 to the plug device 3. Particularly, when the actuator 44 is aligned with the projections 32 for forcing the projections 32 into the depressions 22 of the article 20 (FIGS. 6-8) and for locking the article 20 to the housing 31, the latch 45 may engage with the catch 37 and may lock the hanger device 4 to the plug device 3, and may prevent the actuator 44 from being disengaged from the projections 32, and thus may prevent the article 20 from being disengaged and removed from the plug device 3 and the hanger device 4.
Referring next to FIGS. 9 and 10, after displaying purposes, or after the user has bought the display device, the [0038] bar 371 and the catch 37 may be removed from the casing 33, such that the latch 45 will not engage with the catch 37. In this condition, the actuator 44 may also be rotated to align and to force the projections 32 into the depressions 22 of the article 20 (FIGS. 6-8), for locking the article 20 to the housing 31 of the plug device 3; and may also be rotated away from the projections 32 (FIG. 5), for allowing the projections 32 to be disengaged from the depressions 22 of the article 20 and for allowing the article 20 to be disengaged from the housing 31 of the plug device 3.
Accordingly, the display device in accordance with the present invention includes a lockable configuration for locking an article for sale and for preventing the article from being taken by the unauthorized persons, and includes a reusable configuration for allowing the article to be hung onto a support with the display device after the article is unlocked from the display device.
