Abstract:
1. A fastening device adapted to fasten a first article to a second article, said fastening device comprising: a first hook adapted to be disposed on the first article and having at least one inclined surface; two positioning plates adapted to be disposed on the first article and respectively located in front of and behind said first hook, each of said positioning plates including at least one positioning guide track, said positioning guide track of each of said positioning plates including an upright slot portion having an open bottom end and defined by an inclined bottom wall surface, a curved guiding slot portion having top and bottom ends in spatial communication with said upright slot portion and located at a side of said upright slot portion distal from said first hook, and a stop shoulder disposed between a top end of said upright slot portion and said top end of said curved guiding slot portion; at least one pair of fixed plates spaced apart from each other in a front-to-rear direction and adapted to be disposed on the second article, each of said fixed plates including a first positioning portion; and at least one second hook including an upright plate body connected pivotally between each pair of said fixed plates, a hook body extending from a top end of said plate body and engaging removably said first hook, two guiding rods extending from said top end of said plate body and spaced apart from and respectively located in front of and behind said hook body, said hook body having an inclined surface, and two second positioning portions extending from a lower end of said plate body and engaging respectively and removably said first positioning portions of said fixed plates so as to prevent rotation of said second hook relative to said fixed plates, each of said guiding rods including a guiding stub that extends from an upper end thereof, that abuts against said stop shoulder of a respective said positioning guide track of a corresponding one of said positioning plates, and that is inserted into and guided by said upright slot portion of said positioning guide track of the corresponding one of said positioning plates to abut against said stop shoulder of a respective said positioning guide track of the corresponding one of said positioning plates during assembly of a corresponding one of said guiding rods to the corresponding one of said positioning plates, wherein when the first and second articles are operated to move toward each other, said guiding stubs of said guiding rods of said second hook move respectively into said upright slot portions through said open bottom ends and on said inclined bottom wall surfaces, such that said inclined surfaces of said first and second hooks move on each other to flex said guiding rods relative to said upright slot portions to thereby allow said inclined surfaces of said first and second hooks to move past each other, wherein when the first and second articles are operated to separate from each other, said guiding stubs of said guiding rods of said second hook move respectively from said upright slot portions of said positioning guide tracks of said positioning plates into said curved slot portions of said positioning guide tracks of said positioning plates, and then move respectively along said curved slot portions of said positioning guide tracks of said positioning plates to pivot said plate body and, thus, said guiding stubs relative to said fixed plates, so as to disengage said second positioning portions from said first positioning portions, respectively, to thereby pivot and separate said hook body of said second hook from said first hook.
