Abstract
Disclosed are collapsible beds and bed frames. A collapsible bed frame includes first and frame units disposed side by side and connected with each other at their proximal sides. Each of the first and second frame units comprises a plurality of bar units. Adjacent bar units are connected with each other and rotatable with respect to each other along one or more axes each substantially perpendicular to a first plane defined by a top surface of the collapsible bed frame when it is expanded. The first and second frame units can contract and expand while remaining on the first plane and while connected with each other.

A collapsible bed frame comprising:
- a first frame unit and a second frame unit disposed side by side, each comprising:
- an upper frame;
- a lower frame disposed below and spaced apart from the upper frame;
- and
- a plurality of first vertical supporting bars disposed between the upper and lower frames, each first vertical supporting bar having an upper end connected with the upper frame and a lower end connected with the lower frame;
- and
- two first connectors connecting the first and second frame units at their proximal sides, wherein each first connector comprises a first body, a lower first coupler and a lower second coupler, an upper first coupler and an upper second coupler, wherein the lower first and second couplers are disposed at a lower portion of the first body and the upper first and second couplers are disposed at an upper portion of the first body, wherein each of the lower first coupler, lower second coupler, upper first coupler and upper second coupler is rotatable along a first axis of the first body, and the first axis of the first body of each first connector is substantially perpendicular to a first plane defined by a top surface of the collapsible bed frame when it is expanded;
- wherein:
- the upper frames of the first and second frame units are fixedly connected with the upper first and second couplers of the two first connectors;
- the lower frames of the first and second frame units are fixedly connected with the lower first and second couplers of the two first connectors;
- each of the first and second frame units is able to contract and expand while remaining on the first plane;
- and
- each of the first and second frame units has a middle pivoting portion, such that when in an intermediate state between contracted and expanded states, left sides of the first and second frame units collectively form a substantially “W” shape, and right sides of the first and second frame units form another substantially “W” shape.

A collapsible bed frame comprising:
- a first frame unit and a second frame unit disposed side by side and connected with each other at their proximal sides;
- and
- two first connectors disposed between the first and second frame units to connect the first and second frame units;
- wherein each of the first and second frame units comprises a plurality of bar units, each bar unit in the plurality of bar units comprising an upper bar and a lower bar disposed below and spaced apart from the upper bar, wherein adjacent bar units are connected with each other and rotatable with respect to each other along one or more axes, wherein each axis is substantially perpendicular to a first plane defined by a top surface of the collapsible bed frame when it is expanded, thereby allowing the first and second frame units to contract and expand while remaining on the first plane;
- wherein the plurality of bar units of each of the first and second frame units moves toward the proximal sides of the first and second frame units during contraction, and moves away from the proximal sides of the first and second frame units during expansion;
- and
- wherein each of the two first connectors comprises:
- a first body having a first axis substantially perpendicular to the first plane defined by the top surface of the collapsible bed frame when it is expanded;
- an upper first coupler and an upper second coupler disposed at an upper portion of the first body and rotatable along the first axis of the first body, wherein the upper first and second couplers are fixedly connected to upper bars of the first and second frame units and
- a lower first coupler and a lower second coupler disposed at a lower portion of the first body and rotatable along the first axis of the first body, wherein the lower first and second couplers are fixedly connected to lower bars of the first and second frame units.
