A device for connecting a cross member and a stand member of a bunk bed includes a support tube and a connecting tube. The end portion of the cross member is disposed with a connecting base that has a conical hole running vertically throughout. A shaft sleeve is disposed in the conical hole. The external surface of the shaft sleeve and the side surface of the conical hole form a pair of coupled slope surfaces. The end face of the connecting tube is disposed with a plurality of grooves, so the bottom end portion of the side wall of the connecting tube forms with a plurality of elastic clamping jaws. One end of the support tube is inserted to the connecting tube. The shaft sleeve is sleeved on the connecting tube, the connecting base squeezes the shaft sleeve to make the two slope surfaces, contact tightly.

A structure for connecting a post and a beam of a bunk bed includes a support tube located above the beam. A connection tube is located below the beam. An end portion of the beam is provided with an insertion connection portion connecting the support tube and the connection tube. The insertion connection portion and the support tube have a pair of slanted surfaces disposed opposite to each other. When the support tube and the insertion connection portion are connected by insertion, the slanted surface of the insertion connection portion tightly fits the slanted surface of the support tube. The insertion connection portion and the connection tube have a pair of slanted surfaces disposed opposite to each other. When the connection tube and the insertion connection portion are connected by insertion, the slanted surface of the insertion connection portion tightly fits the slanted surface of the connection tube.

A bed frame and cover that is capably joinable to another bed frame and cover and capably disjoinable from another bed frame and cover and of which comprises a mattress supporting plate which is capable of moving vertically within the cover. The cover is a unified structure of walls and a roof with pivotally connected doors that capably form an enclosure around the plate or of which are stowable on the roof. The entire cover is capable of 360 degree bi-directional rotation around the entire plate as well as vertical movement. A capably pivotable mattress attachment is stowable under the plate or extends to form a contiguous mattress surface of which is supported by rods that connect to another bed frame and cover. The bed frame and cover is capable of a multitude of configurations dependent on bed frame, mattress attachment and the cover's optional positioning.

A metal mattress platform includes a plurality of interconnected metal bars disposed in a common plane and forming a generally rectangular frame and at least four legs. Upper surfaces of the metal bars define a platform surface of the metal mattress platform. Each leg is disposed proximate a respective corner of the rectangular frame. The legs are sufficiently long to position the generally rectangular frame a relatively high distance above the ground, such as about sixteen inches or more. In some embodiments, the platform may include two or more panels, some of which may be hingedly attached to one another to allow the platform to be folded to smaller dimensions for shipping or storage.

A co-sleeper bed system includes a primary bed framework having a primary enclosure that includes a floor and first and second side guide rails defining an open top for receiving a primary mattress. The bed system includes an auxiliary bed frame having frame members that receive an auxiliary mattress, the auxiliary bed frame having a first support leg depending from the plurality of frame members. The first support leg includes a flange slidably received in a channel of the first guide rail. The bed system includes a crib framework having a floor for supporting a crib mattress and a plurality of leg hubs each having a truncated configuration extending downwardly. A pair of slider flanges is attached to a pair of inner leg hubs, each slider flange being slidably received in the channel of the second guide rail for removably coupling the crib framework to the primary framework.

A folding bed includes first and second bedsteads and one or more connection members coupling the first and second bedsteads. A connection member can be a frame or a leg connection member. A frame connection member includes first and second vertical end portions to removably couple adjacent peripheral bars of the first and second bedsteads. A leg connection member includes first and second engaging members to removably couple adjacent legs of the first and second bedsteads. The one or more connection members reduce the risk of bending the folding bed and assist in stabilizing the folding bed when in use.

A folding bed includes first and second unit bedsteads and one or more connection members coupling the first and second unit bedsteads. Each of the first and second unit bedsteads includes a frame with a peripheral bar. The peripheral bar of the frame of the first unit bedstead and the peripheral bar of the frame of the second unit bedstead are adjacent to each other. Corresponding to each respective unit bedstead, each connection member includes a horizontal member, and first and second vertical end portions at first and second edges of the horizontal member respectively. When the folding bed is unfolded, the horizontal member abuts a top surface or a bottom surface of the peripheral bar of the frame of the respective unit bedstead, and the first and second vertical end portions are disposed at an internal side of the respective unit bedstead.

A portable readily assembled and dismantled bunk bed has flexible bed support members with integral flexible head and foot and vertically disposed members that disconnectably engaged and hold the flexible bed support to a horizontal frame member and provide end members that prevent a child from sliding through the frame members.

A supporting device for a foldable bed frame includes a hinge at an upper end of an upper support member, a movable support member vertically movable on the upper support member, a bracket on the movable support member, and first and second diagonal pull rods, a first end of each pull rod pivotally attached to the bracket, and a second end of each pull rod pivotally attached to the first upper bed frame and to the second bed frame, respectively.

A simple bed base connection structure includes a connecting part, groove parts on both sides of the connecting part for connection with outer rails of adjacent bed frames, a locking member that is detachably connected to the connecting part, and an edge retainer. When the locking member is connected and locked with the connecting part, the edge retainer presses the frame of each adjacent bed frame into the groove parts. The bed base connecting structure allows for easy assembly and easy expansion from a small bed to a large bed.
