Abstract:
A cabinet and drawer assembly structure comprising a cabinet assembly having two identical rear panels juxtaposed together and fastened to two side panels at two sides and an upper panel and a lower panel, and the side panels having respectively an inner side with a slide roller channel mounted thereon for supporting a drawer assembly, wherein:the two rear panels are identically shaped and formed, each rear panel having two first square channels located at two sides thereof which form respectively a trough therein, the first channel on the left hand side of each rear panel having an upper end and a lower end each having a screw bore formed. therein, the first channel on the right hand side of each rear panel having an upper end and a lower end each having a key hole formed therein, the key holes having a longitudinal slot for receiving and engaging with a ball screw rod to fasten the two juxtaposed rear panels, the two side panels having respectively a second rear square channel and second forward square channel located at two sides thereof which have a trough formed therein; the second rear square channel of each side panel having screw bores formed at the upper end and lower ends thereof for fastening to the rear panels, each of the rear panels having a jut edge formed on the top end thereof to wedge in a wedge slot formed on the peripheral rims of the upper panel, the lower panel having a notch formed on a rear rim thereof to match and engage with the bottom ends of the coupled first inner channels of the rear panels; the second forward channel of the side panels having an anchor block extended from the bottom ends thereof, each of the anchor blocks having an aperture formed therein, the apertures of the anchor blocks and the troughs of the second rear and forward square channels allowing wedge legs of a transverse beam to wedge in, the side panels having jut edges formed at the top ends thereof to wedge in the wedge slot formed on the peripheral rims of the upper panel, the second rear square channel of a right one of the side panels having screw bores formed at the upper ends and lower ends thereof for fastening to one of the first square channels of one of the rear panels through the ball screw rods in key holes at the slots, the left one of the side panels being attached to another one of the rear panels, the second rear and forward square channels of each side panel having an inner side facing each other with equally spaced wedge notches formed thereon facing wedge notches of both of the side panels engaging with snap fingers of a bracket, each of the brackets having a nose section to support a partition for forming a holding space; the wedge slot formed on the peripheral rims of the upper panel extends downwardly for receiving the jut edges formed at the top end of the rear panels and side panels to be wedged in and coupled securely thereto; the lower panel has the left, right and rear sides bent respectively to form a third square channel with a trough formed inside, the lower panel having notches formed at two ends of two sides thereof to wedge and couple with the side panels, the front edge of the lower panel being extended forwards to form a jutting ledge to match and contact a front panel; and the drawer assembly includes a bottom plate, two opposing side plates, a rear plate, a front plate and a coupling frame, wherein: the bottom plate has two rods located below two sides thereof to couple with a slide channel extended from an inner side of the bottom of the side plates, the side plates being turnable about the rod for resting on the bottom plate for folding, the bottom plate having a rear edge extended upwards to form a jutting flange which has wedge tongues extending outwards formed by punching to engage with square openings formed on the rear plate; the side plates each having a slide channel formed on a side thereof in addition to the slide channel formed on the bottom thereof, each of the slide channels on the sides being slidably engageable with a rod located on one of the side edges of the rear plate, a forward side of the side plates forming a coupling plate extended outwards, each of the coupling plates having a wedge lug proximate to the top end thereof formed by punching, the front plate having a U-shaped frame attached thereon with two troughs formed at two sides for receiving the coupling plates, the frame having a plank bordering the trough and having square wedge apertures matching and engaging with the wedge lugs, the side plates each having an extended ledge formed on the top end thereof which have a plurality of anchor slots for holding latch lugs located at two sides of a top end of separators; the square openings of the rear plate are proximate the bottom thereof; and the front plate having a shaped wedge plate extended from two sides thereof to couple with indented recesses formed on the inner rim of the coupling frame; whereby the drawer assembly is accomplished by coupling the two side plates with the bottom plate by sliding the rods into the slide channels, then turning the side plates inwards and resting the side plates flatly on the bottom plate, then stacking the rear plate, the front plate and the coupling frame, and transporting to a users' site, turning the two opposing side plates to positions desired, wedging the rods at two sides of the rear plate into the side slide channels of the side plates, and engaging the square openings of the rear plate with the wedge tongues of the bottom plate, and wedging the coupling plates of the side plates into the troughs at two sides of the U-shaped frame attached to the inner side of the front plate with the coupling frame coupled thereon; and then juxtaposing and assembling the two rear panels of the cabinet, fastening the two side panels and the upper panel and the lower panel through the ball screw rods, and wedging and fastening respectively the upper end and lower end of the front side and the rear side of the top section of the rear panels and side panels with the transverse beam, then fastening the upper panel and the lower panel to complete the cabinet and drawer assembly.
