The bends it of elements 68 abut the upper ends of the rear members 55 and members 2 i, 35 on the wall i2. When the elements 66 are in looking position the sid walls, partition and rear wall are connected together and arranged vertically. When the wall 22 is disposed vertically it conceals the bends 13 of, elements 5? and prevents the rearward 'fting of the latter. The forward shifting elem nts 6? is prevented by the coaction of the thereof with the rear of the ends of the lower members Ed and the members 23, bottom The outer looking members of the set lid extend through the member 3:? on top hi and the upper members 5% on the sidewalls for locking the exte lSlOILS t! on top i to the upper combined edges reinforcing and coupling members 5:3 carried by the side walls, and the intermediate locking element of set extends through member on top 56 and the upper member til on partition it for locking the extensions 2? on top it to the upper combined edge reinforcing coupling member 59 carried by partiti The handles E2 of the elements Gil oppose I walls and a side face of the partition H5. The bends T3 of element 89 abut the front ends of the members on top and the front ends of the upper members on the side walls and partition. The elements 69 when in looking position provi for the top if to be anchored upon the side walls and partition and conceal the handle of element es as well as prevent the upward shifting of latter. The outer elements of the set ill extend through member 35 on front wall it and through the front members 5i on the side walls for locking the extensions 42 on wall it to the front combined edges reinforcing and coupling members 5! carried by the side walls and the intermediate locking element of set it extends through the member 23 on front wall is and the front member 55 on partition it for looking the extensions 2% on front wall 53 to the front combined edge reinforcing and coupling member 51 carried by partition it. The elements lil maintain the front wall l3 in a vertical position. The front wall is conceals the handle ends of the locking elements 59. The handles 52 of the elements ill oppose the outer faces of the front wall 53 so that access may be conveniently had to them when it is desired to open or knock down the case. The bends l3 of the elements iii abut the top edges of the front wall it. The latter is locked in upstanding position at three points. The locking elements are to be of a size to be frictionaily held when in locking position.
