Tabletop folded sheet dispenser

A system comprising:

• a dispenser for dispensing sheet material, comprising:
• a body having four side walls and defining an opening at a top portion thereof;
• a base;
• a lid configured to cover the opening during use and enabling access to the opening for refilling, wherein the lid has a dispensing opening therein configured to enable sheet material to be dispensed therefrom,
• a platform configured to support a plurality of sheet material from below, wherein the platform is movable from a lowermost position when the dispenser is filled with sheet material to an uppermost position adjacent the lid when the dispenser is more nearly empty of sheet material,
• a spring for urging the platform towards the lid,
• a releasable locking mechanism configured to hold the platform in a locking position in the lowermost position, the releasable locking mechanism comprising:
• a first pair of first arms movably attached to one of the side walls and extending in a direction from the top towards the base of the body, wherein one first arm of the first pair of the first arms has a first top end and a first base end, and another first arm of the first pair of the first arms has a second top end and a second base end,
• a second pair of second arms movably attached to the base and extending in a direction from the side wall to which the first pair of the first arms is attached towards a center of the base, wherein one second arm of the second pair of the second arms has a first side wall end and a first locking end, and another second arm of the second pair of the second arms has a second side wall end and a second locking end,
• wherein the first side wall end is configured to cooperate with the first base end and the second side wall end is configured to cooperate with the second base end such that a movement of the one first arm and the another first arm respectively causes a movement of the one second arm and the another second arm, the first locking end and the second locking end being configured to releasably interlock respectively with first and second locking portions arranged at the platform to thereby hold the platform in the locking position,
• wherein the lid has a pair of first and second engaging portions at a lower surface thereof, and
• wherein the first and second engaging portions are configured to engage, respectively, with the first top end of the one first arm and the second top end of the another first arm upon closing the lid to thereby release the platform from the locking position.
