Abstract:
A freely connectable chest unit, comprising two sidewall panels, a top panel, a bottom panel, a back panel, and a door assembled into said chest unit by means of a first fastening mechanism, a second fastening mechanism, and a door-closing mechanism;said first fastening mechanism being used to assemble said sidewall panels to said top and said bottom panel, and including more than one first fastening member separately movably mounted to predetermined points on upper and lower peripheral edges of said two sidewall panels, and receiving spaces formed on said top and said bottom panels corresponding to said first fastening members; each of said first fastening member being adapted to receive in a corresponding one of said receiving spaces at a released position when said two sidewall panels are connected to said top and said bottom panels, and said first fastening member being forward movable from said released position to a fastened position in said receiving space to firmly hold said top and said bottom panel to said sidewall panels; said second fastening mechanism being used to horizontally connect a first and a second said chest unit to each other side by side, and including more than one second fastening member, each of which including a turning knob, a connecting shaft extended from a rear surface of said turning knob by a length decided in accordance with a total thickness of two adjacent sidewall panels of said first and said second chest unit to be horizontally connected, and a long locking plate extended across a free end of said connecting shaft opposite to said turning knob; and mounting holes provided at predetermined positions along borders of said two sidewall panels of said chest unit; each of said second fastening members being adapted to mount in one of said mounting holes on one of said two sidewall panels of said first chest unit with said turning knob located in said mounting hole and said connecting shaft extended through one of said two sidewall panels of said second chest unit adjacent to said first chest unit to locate said locking plate in a corresponding one of said mounting holes on said sidewall panel of said second chest unit, and said turning knob being turnable to orient said locking plate perpendicularly to said mounting hole on said sidewall panel of said second chest unit and thereby firmly holding said second chest unit to said first chest unit at said two adjacent sidewall panels; said door-closing mechanism being used to connect said door to any one of said two sidewall panels of said chest unit and including a door-closing member, a mounting compartment provided behind an upper part of said door for mounting said door-closing member therein, a top through hole formed at a top of said mounting compartment, and a pivot shaft provided behind a lower part of said door corresponding to said door-closing member; said door-closing member mainly including a pivot pin having an end upward extended through said top through hole on the top of said mounting compartment, a first elastic element put around said pivot pin to allow said pivot pin to move up and down relative to said door, and a second elastic element put around a lower part of said first elastic element; and said second elastic element having a first hooked end being engaged with said door, and a second hooked end being engaged with said sidewall panel to which said door is connected; said two sidewall panels being so structured that they are exchangeable to allow horizontal connection of two or more said chest units to one another; said top and said bottom panel also being structured to be exchangeable in assembling said chest unit to allow vertical connection of two or more said chest units to one another; and said door-closing member automatically closing said door when said second hooked end of said second elastic element is engaged with said sidewall panel; and said second hooked end of said second elastic element being removable from said sidewall panel to engage with said door to allow said door to be closed manually.
