Abstract

A flooring system includes multiple panels (10) which are connected to each other by connectors (20). Each panel (10) has a tongue (30) and each connector (20) has an engaging slot (40). The tongue (30) does not extend beyond the side of the panel (10). The panel (10) is moved horizontally to insert the lower protrusion (300) of the tongue (30) into the lower recess (400) of the engaging slot (40) of the connector (20). The inner inclined face (302) of the lower protrusion (300) of the tongue (30) contacts the curved wall (410) of the lower recess (400) of the connector (20). The tongue (30) of the panel (10) is engaged with the engaging slot (40) of the connector (20) by way of pressing the panel in a direction perpendicular to the panel. No hammering to the side of the panel is needed.
