Document holder with a quick-release fastening device

A document holder comprising:

• a casing having left and right walls that define therebetween a document chamber, and an opening via which access into said document chamber is possible;
• a lid connected to one of said left and right walls and turnable relative to said casing to a closed position for covering said opening of said casing;
• and
• a quick-release device including
• a strap engaging member having a plate fixed on said lid to define a strap engagement space therebetween, said plate having a distal free end spaced apart from said one of said left and right walls to define therebetween an entrance via which access into said strap engagement space is possible,
• a non-elastic strap having a fixing section fixed to one of said strap engaging member, said casing and said lid, a pulling section opposite to said fixing section and exposed from said strap engaging member and said casing and said lid, and a middle section extending between said fixing and pulling sections and spanning said distal free end of said strap engaging member, said pulling section being operable to move said middle section,
• a stop member for preventing movement of said pulling section of said non-elastic strap into said strap engagement space, and
• an elastic strap mounted on said casing and said lid, and being elastically stretchable to pull said lid to said closed position, in which, said elastic strap passes through said entrance and pulls said middle section of said non-elastic strap into said strap engagement space such that said middle section defines an inverted U-shaped portion that straddles over a portion of said elastic strap in said strap engagement space and a U-shaped portion that inversely straddles over said distal free end of said strap engaging member, thereby pulling said lid against said casing;
• whereby, a manually pull of said pulling section results in movement of said inverted U-shaped portion, which in turn, results in movement of said elastic strap from said closed position toward said entrance so that said elastic strap is disengaged from said middle section of said non-elastic strap immediately after passing through said distal free end of said strap engaging member, thereby permitting opening of said lid relative to said casing.
