The present invention is provided with a structure for connecting a cross member and a stand member of a bunk bed and a bunk bed. With two pairs of inclined surfaces, the cross member, the upper stand member, and the lower stand member can be quickly connected. The assembly and disassembly are quite convenient, time saving and labor saving.

A frame structure of an electric bed includes a detachable upper frame and a detachable lower frame, wherein the upper frame includes wheels, and the lower frame includes rail slots. The lower frame can be separated into a front lower frame and a rear lower frame; the front lower frame includes a front lower frame main body and front lower frame mounting portions on both sides of the front lower frame main body; the rear lower frame includes a rear lower frame main body and rear lower frame mounting portions on both sides of the rear lower frame main body; and wherein the front lower frame mounting portions and the rear lower frame mounting portions are connected by screws; and the front lower frame main body and the rear lower frame main body together form an accommodating space for accommodating a driving structure of an electric bed.

The present invention is directed to a bed frame designed for quick assembly. In an exemplary embodiment, the invention may comprise a wire lattice that forms the support surface for a mattress and, if necessary, box springs. The wire lattice can be secured to a perimeter frame using brackets which hook onto the lattice and also attach to the sides of the frame. The bed frame may include vertical supports or legs that can be quickly attached to the frame. Each leg may include an attachment plate and a catch extending above the attachment plate. The leg can be secured to the bed frame by sliding the attachment plate into a receiver attached to the bed frame. As the attachment plate is being inserted, the catch may engage a series of corrugations formed in the receiver. The catch may press against a corrugation to lock the leg into the receiver.

A mattress foundation includes: a head end panel assembly; a foot end panel assembly; a left side panel assembly; and a right side panel assembly, all slidably attaching to each other using sliding mechanisms. At least one of the sliding mechanisms includes an elongated slot and an elongated protruding element that fits within the elongated slot. A horizontal cross-section of the elongated slot and/or the elongated protruding element includes thin elongated flexible arms, attached at their proximal ends to a common surface, but otherwise extending away from such common surface and separated from each other. When viewed from the horizontal cross-section, the average thickness of the thin elongated flexible arms is substantially less than the length of the thin elongated flexible arms.

A locking arrangement for assembly of a bed frame is provided. The locking arrangement comprises a first rail member comprising at least two first projecting interlocking holes and a second rail member comprising at least two sets of second projecting interlocking holes. The locking arrangement further comprises a set of pins such that, in assembled form of the bed frame, the first rail member and the second rail member are disposed in abutment with each other such that each of the at least two first projecting interlocking holes are received within one set of the at least two sets of second projecting interlocking holes to form a provisional locking structure, and each pin of the set of pins is engaged with one of the formed provisional locking structure by passing through the corresponding first projecting interlocking holes and second projecting interlocking holes thereof, to secure the first rail member and the second rail member.

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.
