Abstract: A knapsack is made of a hard thermoplastic material and is molded into a single-piece construction. The knapsack has a rear wall surface facing toward a user's back and formed with a plurality of spacers to result in a spacing between the rear wall surface and the user's back. As a result, the knapsack does not attach closely to the user's back and, therefore, permits air ventilation and can provide a massaging effect.

Abstract: An expandable file folder includes a base wall, two cover walls extending from the base wall, two expandable end walls connected to the cover walls to confine a document holding space, and a plurality of partitions dividing the document holding space into volume variable spaces such that the end walls can expand for stuffing documents into the spaces. A bracing member is secured to lower portions of the cover walls adjacent to the base wall so as to maintain a distance between the lower portions when the stuffed documents cause bulging of the file folder.

Abstract: A document holder includes a flat base part, front and rear wall parts, a pair of lateral wall parts, and a cover part. Each of the front and rear wall parts extends upwardly from a respective one of front and rear edges of the base part. The lateral wall parts extend between the front and rear wall parts, and cooperate with the latter to confine a document holding space with an open top. The cover part is hinged to the rear wall part, is movable so as to cover and uncover the open top of the document holding space, and is formed with a window section that permits viewing into the document holding space when the latter is covered by the cover part.

Abstract: A document holder includes a case body having an elongate base part, and first and second casing parts. The elongate base part has opposite longitudinal edges, a bottom surface, and a top surface. The top surface is mounted with a ring binder unit that is adapted for binding removably loose-leaf document holding sheets. Each of the first and second casing parts has an outer casing surface, a recessed inner casing surface opposite to the outer casing surface, and a hinge edge connected pivotally to a respective one of the longitudinal edges of the base part such that the first and second casing parts are movable between folded and unfolded positions relative to the base part.

Abstract: A document holder includes a casing and a lid for covering an opening of the casing. A quick-release device includes a strap engaging member fixed on the lid to define a strap engagement space with an entrance for access thereinto. A non-elastic strap has a fixing section fixed to the lid, a pulling section, and a middle section which spans a distal free end of the strap engaging member. A stop member prevents movement of the pulling section into the strap engagement space. An elastic strap is mounted on the casing, and is elastically stretchable to pull the lid to a closed position. Under this condition, the elastic strap passes through the strap engaging member and pulls the middle section into the strap engagement space such that the middle section defines an inverted U-shaped portion that straddles over a portion of the elastic strap in the strap engagement space and a U-shaped portion that inversely straddles over the distal free end of the strap engaging member.
