Self-closing security door assembly for retail display

A self-closing door assembly for limiting access to goods in a shelving system that includes a lower shelf for displaying the goods and an upper shelf having a front edge, the assembly comprising:

• a frame assembly configured to be joined with the shelving system adjacent the front edge of the upper shelf;
• a guide rail assembly positioned in fixed relationship to the frame assembly and parallel with the front edge of the upper shelf, the guide rail assembly including a first end;
• a first door suspended along the guide rail assembly and moveable between a first closed position that interferes with manual access to the goods disposed on the lower shelf and a first open position that enables manual access to goods disposed on the lower shelf;
• and
• a first biasing member disposed between the frame assembly and the first door to urge the first door in a horizontal direction toward the first closed position, the first door configured for manual engagement to be urged toward the first open position, the first biasing member arranged to return the first door to the first closed position upon manual release thereof,
• wherein the first biasing member includes a first spool joined with a first coiled spring within a first housing, with a first cord wrapped around the first spool and retractable thereon under force generated by the first coiled spring,
• wherein the first spool is mounted beyond the first end of the guide rail assembly, and beyond the first door when the first door is in the first closed position,
• wherein the first housing is mounted to a first bracket,
• wherein the first bracket defines at least one of a recess and a hole,
• wherein the first cord extends through the at least one of the recess and the hole toward the guide rail assembly, above the first door.

A self-closing door assembly for limiting access to goods in a shelving system that includes a lower shelf for displaying the goods and an upper shelf having a front edge, and an upper shelf above the lower shelf, the assembly comprising:

• a guide rail assembly including a first guide rail configured for fixed mounting substantially parallel to the upper shelf above the lower shelf;
• a first door vertically suspended along the first guide rail, the first door being moveable along the first guide rail to thereby move laterally between a first closed position that interferes with manual access to the goods disposed on the lower shelf and a first open position that enables manual access to the goods disposed on the lower shelf;
• a second door vertically suspended along the first guide rail adjacent the first door, the second door being moveable along the first guide rail to thereby move laterally between a second closed position that interferes with manual access to the goods disposed on the lower shelf and a second open position that enables manual access to the goods disposed on the lower shelf, the first door and the second door being arranged in an overlapping configuration;
• a first biasing member including a first cord extending from a first housing outwardly to a first connector joined with the first door such that the first biasing member urges the first door toward the first closed position;
• and
• a second biasing member including a second cord extending from a second housing outwardly to a second connector joined with the second door such that the second biasing member urges the second door toward the second closed position, the first cord and the second cord respectively urging the first door and the second door in opposing directions,
• wherein the first door and the second door are adapted for manual engagement to be manually urged toward at least one of the first open position and the second open position, respectively,
• wherein the first biasing member laterally moves the first door from the first open position to the first closed position upon manual release of the first door with the first cord retracting into the first housing,
• wherein the second biasing member laterally moves the second door from the second open position to the second closed position upon manual release of the second door with the second cord retracting into the second housing,
• wherein the first biasing member includes a first spool joined with a first coiled spring, the first cord wrapped on the first spool and retractable thereon,
• wherein the first spool is mounted a first distance inward and distally from the front edge of the upper shelf, rearward of the first door and first guide rail,
• wherein a first redirection element is disposed along the first cord between the first spool and the first door, and is disposed under the upper shelf, above the first door,
• wherein the first door hangs under aforce of gravity and is suspended and movably disposed in a second guide rail of the guide rail assembly below the first guide rail.

A self-closing door assembly system comprising:

• a lower shelf configured to displaying goods thereon to a consumer;
• an upper shelf having a horizontal surface and a downwardly extending front flange that extends to a forward edge;
• a frame assembly removably joined adjacent the front edge of the upper shelf;
• a guide rail assembly positioned in fixed relationship to the frame assembly and parallel with the front edge of the upper shelf, the guide rail assembly including a first end and a first guide rail of the guide rail assembly positioned rearward of the front flange;
• a first door suspended along the first guide rail and moveable between a first closed position that interferes with manual access to the goods disposed on the lower shelf and a first open position that enables manual access to goods disposed on the lower shelf;
• and
• a first biasing member disposed between the frame assembly and the first door to urge the first door in a horizontal direction toward the first closed position, the first door configured for manual engagement to be urged toward the first open position, the first biasing member arranged to return the first door to the first closed position upon manual release thereof,
• wherein the first biasing member includes a first spool joined with a first coiled spring within a first housing, with a first cord wrapped around the first spool and retractable thereon under force generated by the first coiled spring,
• wherein the first spool is mounted beyond the first end of the first guide rail, and beyond the first door when the first door is in first closed position.
