Suitcase having reinforcing structure

Abstract

A suitcase includes an enclosure having a chamber formed by an outer peripheral wall and a bottom wall each having an outer peripheral flange folded inwardly to form a peripheral recess, and a cover member attached to the enclosure. A reinforcing frame is engaged into the enclosure, for bracing and reinforcing the enclosure, and includes an end edge fitted into the peripheral recess of the outer peripheral wall, for stably anchoring the reinforcing frame to the enclosure. A reinforcing strap may be attached to reinforce the enclosure with an outer sleeve. The reinforcing frame may include an inclined surface to form a sharpened end edge, for snugly fitting into the peripheral recess of the outer peripheral wall.

1 . A suitcase comprising: 
 an enclosure including a chamber formed therein, and defined by an outer peripheral wall and a bottom wall, said outer peripheral wall including an outer peripheral flange folded inwardly to form a peripheral recess therein,    a cover member attached to said enclosure, for enclosing said chamber of said enclosure, and    a reinforcing frame engaged into said chamber of said enclosure, for bracing and reinforcing said enclosure, said reinforcing frame including an end edge fitted into said peripheral recess of said outer peripheral wall, for stably anchoring said reinforcing frame to said enclosure.    
   
   
       2 . The suitcase as claimed in  claim 1 , wherein said bottom wall includes an outer peripheral flange folded inwardly, and secured to said outer peripheral flange of said outer peripheral wall.  
   
   
       3 . The suitcase as claimed in  claim 2 , wherein a reinforcing strap is attached to said outer peripheral flanges of said outer peripheral wall and said bottom wall, for reinforcing said enclosure.  
   
   
       4 . The suitcase as claimed in  claim 3 , wherein an outer sleeve is provided and attached to said outer peripheral flanges of said outer peripheral wall and said bottom wall, for receiving said reinforcing strap.  
   
   
       5 . The suitcase as claimed in  claim 4 , wherein said outer sleeve includes a longitudinal channel therein, to receive said longitudinal strap therein, and includes at least one flange engaged between and secured to said outer peripheral flanges said outer peripheral wall and said bottom wall.  
   
   
       6 . The suitcase as claimed in  claim 1 , wherein said reinforcing frame includes an inclined surface formed therein, and located close to said end edge thereof, to form a sharpened structure for said end edge, and to allow said sharpened end edge to be snugly fitted into said peripheral recess of said outer peripheral wall.  
   
   
       7 . The suitcase as claimed in  claim 6 , wherein said reinforcing frame includes a honey-comb structure having an outer peripheral panel, an inner peripheral panel, and a plurality of ribs provided between said peripheral panels, said inclined surface is formed in said inner peripheral panel of said reinforcing frame.  
   
   
       8 . The suitcase as claimed in  claim 7 , wherein said reinforcing frame includes a second inclined surface formed in either said outer peripheral panel or said inner peripheral panel.  
   
   
       9 . The suitcase as claimed in  claim 8 , wherein said cover member is openably attached to said enclosure with a slide fastener, and said second inclined surface of said reinforcing frame is arranged to offset said reinforcing frame from said slide fastener.  
   
   
       10 . The suitcase as claimed in  claim 1 , wherein said reinforcing frame includes two end portions, and at least one peg engaged into said end portions of said reinforcing frame, to couple said end portions of said reinforcing frame together.
