A crib assembly includes a frame to support a mattress, an enclosure having sides defining an enclosure area, and an attachment system including a first and second attachment mechanisms. A first side of the enclosure has a first end and a second end. The first end is configured to removably attach via the first attachment mechanism to a first corner of the enclosure and the second end is configured to removably attach via the second attachment mechanism to a second corner of the enclosure. The first attachment mechanism includes (a) a first bolt located at the first end of the first side or the first corner of the enclosure and (b) a first slot located at the first end of the first side or the first corner of the enclosure, opposite the first bolt. The second attachment mechanism includes (a) a second bolt located at the second end of the first side or the second corner of the enclosure and (b) a second slot located at the second end of the first side or the second corner of the enclosure, opposite the second bolt. The first and second bolts are dimensioned to be slidably received within the respective first and second slots to removably attach the first and second ends of the first side to the respective first and second corners of the enclosure.

A frame unit includes first and second bars spaced apart from each other, third bars disposed between the first and second bars, and connectors removably connecting the third bars with the first and second bars. A connector includes a body fixedly connected with the first or second bar, a casing defining an interior to receive an end of a third bar, and a slot allowing insertion of the end of the third bar into the casing. The interior defined by the casing has narrow and wide sides corresponding to the narrow and wide sides of the end of the third bar. As such, when the end of the third bar is inserted into the casing, the end of the third bar is prevented from any translational movement within the casing. The connectors allow quick and easy connection of bars, and in the meantime enhance the stability of the frame unit.

The present invention relates to the field of bed frame structures, and in particular, to a novel detachable bed frame assembly mechanism. The novel detachable bed frame assembly mechanism includes a bed frame body. The bed frame body includes an outer frame, an inner frame, and two sets of wooden strips. The outer frame is a rectangular frame including two horizontal tubes, two lateral tubes, four L-shaped iron-plate connectors, bolts, and nuts. The inner frame includes at least one horizontal connecting tube, a plurality of lateral connecting tubes, iron sheets, bolts, and nuts. The two sets of wooden strips are symmetrically disposed on the horizontal connecting tube and the horizontal tubes on both sides of the horizontal connecting tube and are parallel to the lateral tubes, to connect the horizontal connecting tube to the horizontal tubes. The invention is easy to assemble and disassemble and is safe and reliable.

An one-piece corner connector for connecting two frame bars at right angles to one another includes a right-angle bracket having two angle legs, an intermediate plate, and two U-profile connecting pieces at right angles, having a middle leg and two side legs for insertion into the plug-in openings in the frame bars which are open at one end. The middle legs of the U-profile connecting pieces are formed on and run with their outer side parallel to the intermediate plate. The one outer side legs of the U-profile connecting pieces are each formed on one of the angle legs and run with their outer side parallel to the outer side of the angle leg. The other inner side legs of the U-profile connecting pieces are connected to one another by means of a wall element which is angled from the intermediate plate.
