Collapsible drawer

Abstract

A collapsible drawer includes a left, a right, a rear, and a front wall being connected at respective lower edge to a left, a right, a rear, and a front edge of a bottom wall to be pivotally turnable relative to the bottom wall between an upright and a folded-down position. A left and a right hook are provided on an inner face of each of the front and the rear wall, and the left and right walls are formed on respective inner face with a front and a rear through hole corresponding to the left and right hooks on the front and rear walls, respectively. By extending the left and right hooks through the front and rear through holes on the left and right walls, the left and right walls are locked to between the front and rear walls in an upright position.

1 . A collapsible drawer, comprising a bottom wall, a left wall, a right wall, a rear wall, and a front wall; the front wall, the left wall, the right wall and the rear wall being pivotally connected at respective lower edge to a front edge, a left edge, a right edge and a rear edge of the bottom wall, and therefore being pivotally turnable relative to the bottom wall between an upright position and a folded-down position; the collapsible drawer being characterized in that:
 a left hook and a right hook are provided on an inner face of the front wall, and the left and the right hook each having a distal hooking end being turned leftward and rightward, respectively; a left hook and a right hook are provided on an inner face of the rear wall, and the left and the right hook each having a distal hooking end being turned leftward and rightward, respectively; the left wall is formed on an inner face at positions corresponding to the distal hooking ends of the left hooks on the front and rear walls with a front and a rear through hole, through which the distal hooking ends of the left hooks on the front and rear walls can be extended, respectively; and the right wall is formed on an inner face at positions corresponding to the distal hooking ends of the right hooks on the front and rear walls with a front and a rear through hole, through which the distal hooking ends of the right hooks on the front and rear walls can be extended, respectively.   
     
     
         2 . The collapsible drawer as claimed in  claim 1 , wherein the distal hooking ends of the left and right hooks on the front wall are in a forked U-shape to have two spaced free ends each, the free ends of the distal hooking ends being elastically compressible toward each other; and the distal hooking ends of the left and right hooks being provided on respective free ends at two opposite outer sides thereof with a vertically protruded rib each; whereby when the distal hooking ends are respectively extended through and beyond the front through holes on the left and right walls, the two free ends thereof elastically expand with the protruded ribs thereof being abutted on an outer periphery of the front through holes. 
     
     
         3 . The collapsible drawer as claimed in  claim 1 , wherein the distal hooking ends of the left and right hooks on the rear wall are in a forked U-shape to have two spaced free ends each, the free ends of the distal hooking ends being elastically compressible toward each other; and the distal hooking ends of the left and right hooks being provided on respective free ends at two opposite outer sides thereof with a vertically protruded rib each; whereby when the distal hooking ends are respectively extended through and beyond the rear through holes on the left and right walls, the two free ends thereof elastically expand with the protruded ribs thereof being abutted on an outer periphery of the rear through holes. 
     
     
         4 . The collapsible drawer as claimed in  claim 1 , wherein the bottom wall is provided along a left, a right, and a rear edge with a raised wall each, whereby when the left and right walls and the rear wall are located in the upright position, bottom edges of the left and right walls and the rear wall are abutted against a top of the raised walls at the left, right and rear edges of the bottom wall. 
     
     
         5 . The collapsible drawer as claimed in  claim 4 , wherein the raised wall at the rear edge of the bottom wall has a height larger than that of the raised walls at the left and right edges of the bottom wall. 
     
     
         6 . The collapsible drawer as claimed in  claim 4 , wherein each of the raised walls at the left and right edges of the bottom wall has a front end, on a top of which a transverse pin hole is provided for an insertion pin to extend therethrough; and wherein the front wall is provided on the inner face at positions corresponding to the two pin holes with two pairs of lugs, and the lugs each being formed with a through hole; whereby when two insertion pins are separately extended through the through holes on the two pairs of lugs and the pin holes corresponding thereto, the front wall is connected to the bottom wall and is pivotally turnable about the insertion pins relative to the bottom wall. 
     
     
         7 . The collapsible drawer as claimed in  claim 6 , wherein the front wall is provided on the inner face at a lower edge thereof with an L-shaped hook, and a downward projected plate is provided on the bottom wall at a lower front edge thereof corresponding to the L-shaped hook; and the L-shaped hook being able to hook to the downward projected plate to thereby keep the front wall in the upright position. 
     
     
         8 . The collapsible drawer as claimed in  claim 6 , wherein the pin holes on the bottom wall are located at a position higher than that of the raised walls at the left and right edges of the bottom wall.
