A bottom bed combination includes a first bed bottom, a second bed bottom, two fastening units and a plurality of stands. The first bed bottom includes a first bed frame, a first bed board, a plurality of first bases a first linkage and a first electric cylinder. The second bed bottom includes a second bed frame, a second bed board, a plurality of second bases, a second linkage and a second electric cylinder. Each of the fastening units includes a mount mounted on the first bed frame and the second bed frame, and a pin extending through the mount, the first bed frame and the second bed frame. The stands are respectively secured on the first bases, the second bases and the fastening units.

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 wrap around bed frame for use in supporting a box spring and mattress having side rails and cross members and a foot member that is affixed to the foot ends of the side rails to provide support for the foot end of the bedding. The entire bed frame can be assembled with fittings that do not require tools for assembly and thus, the bed frame can be assembled easily by the user by simply sliding or snapping the components together. Protective shields cover the bed frame so as to minimize harm to a person inadvertently striking one of the bed frame components. The foot member is comprised of an upper and lower member affixed together. There are also center wedges on the cross members where a foot can be affixed to the center wedge to facilitate assembly of the bed frame.

A bed frame includes outer lateral and longitudinal bar units, each having a first end and a second end. Each of first, second, third, and fourth longitudinal bar units includes an upper longitudinal bar and a lower longitudinal bar. The first ends of the first and second longitudinal bar units are rotatably connected with each other. The first ends of the third and fourth longitudinal bar units are rotatably connected with each other. Of each respective longitudinal bar unit, the second end of the upper longitudinal bar is movably connected with the first or second end of a corresponding lateral bar unit, and the second end of the lower longitudinal bar is fixedly connected with the first or second end of the corresponding lateral bar unit.

A collapsible peripheral frame includes first and second outer lateral bar units, and first and second longitudinal bar assemblies. Each of first and second longitudinal bar assemblies comprises first, second and third longitudinal bar units rotatably connected with each other at their adjacent ends. The first outer lateral bar unit has a first end connected with an end of the first longitudinal bar unit in the first longitudinal bar assembly and a second end rotatably connected with an end of the third longitudinal bar unit in the second longitudinal bar assembly. The second outer lateral bar unit has a first end rotatably connected with an end of the third longitudinal bar unit in the first longitudinal bar assembly and a second end connected with an end of the first longitudinal bar unit in the second longitudinal bar assembly.

A foldable supporting assembly includes an inner lateral bar unit, and first, second, third and fourth longitudinal bar units. The first and second longitudinal bar units are disposed at a first side, and rotatably connected with the first and second ends of the inner lateral bar unit. The third and fourth longitudinal bar units are disposed at a second side, and rotatably connected with the first and second ends of the inner lateral bar unit. When folded, one of the first and second longitudinal bar units is disposed between the inner lateral bar unit and the other one of the first and second longitudinal bar units, and one of the third and fourth longitudinal bar units is disposed between the inner lateral bar unit and the other one of the third and fourth longitudinal bar units.

A bed can include one or more connectors for connecting components of the bed. For example, a frame can include a fastening mechanism for releasably connecting a cross-member to a longitudinal support. Another example includes connectors for connecting and aligning a foundation with a frame.

The invention relates to a fastening system for connecting two frame elements of a bed frame, in particular for an adjustable bed, wherein the two frame elements each comprise a hollow profile, the fastening system comprising: a mounting element, which is firmly attachable to an end of the first frame element, and a connector part, which is insertable into the hollow profile at an end of the second frame element and firmly connectable to second frame element, wherein the mounting element comprises at least one mounting hole, the connector part comprises at least one mounting spigot corresponding to the at least one mounting hole, which is designed to be plugged into the at least one mounting hole, the connector part comprises at least one mounting mechanism for a detachable, firm connection of the mounting element and the connector part.

A corner locking mechanism for a bed base that has corners formed by respective adjacent mating side panels and end panels is provided. The corner locking mechanism has a first section including a first top wall, a first outer wall orthogonal to the first top wall, and a first inner wall extending orthogonally from the first top wall. The corner locking mechanism also has a second section extending orthogonally from the first section, the second section including a second top wall, a second outer wall extending orthogonally from the second top wall, and a second inner wall spaced from the second outer wall and extending orthogonally from the second top wall. The first section is located over one of the side panel or the end panel at the corners.

A bed frame installation structure, having two bed posts spaced apart from each other and a bed support rod; a bottom of each end of the bed support rod is bent and warped into a hook piece, and a top side of which is formed with a locking plate; a locking hole and a hook hole are formed on each bed post corresponding to a corresponding end of the bed support rod; the hook piece is accommodated in a corresponding bed post to engage with a lower edge of the hook hole, and the locking plate is fixed to the locking hole by a screw. A bed frame structure is also disclosed having a bed surface frame and two bed frame installation structures spaced apart from each other; a bed side beam is provided between two corresponding bed posts of the two sets of the bed frame installation structure.
