Abstract
Disclosed are connectors and collapsible bed frames. A collapsible bed frame includes first and second frame units disposed side by side. Each of the first and second frame units comprises a plurality of bar units with adjacent bar units rotatably connected with each other. A collapsible bed frame also includes an inner lateral bar unit disposed between the first and second frame units, and rotatably connected with the first and second frame units. During contraction and expansion, the first frame unit, the second frame unit and the inner lateral bar unit remain substantially on a first plane defined by a top surface of the collapsible bed frame when it is expanded.
Claims18
A collapsible bed frame comprising:
- a first frame unit and a second frame unit disposed side by side;
- an inner lateral bar unit disposed between the first and second frame units;
- and
- two first connectors to connect the first frame unit, the second frame unit and the inner lateral bar unit such that each of the first and second frame units is able to contract and expand while remaining on a first plane defined by a top surface of the collapsible bed frame when it is expanded;
- wherein:
- each of the first frame unit, the second frame unit and the inner lateral bar unit has a first end and a second end;
- each of the two first connectors comprises:
- a first piece comprising an affixing piece, a first extension integrally extended from the affixing piece at a first side of the affixing piece and a second extension integrally extended from the affixing piece at a second side of the affixing piece, wherein the affixing piece is fixedly connected with the first or second end of the inner lateral bar unit, wherein the affixing piece, first extension and second extension are substantially planar and disposed substantially parallel to the first plane;
- a second piece comprising a first segment rotatably connected with the first extension of the first piece, and a second segment fixedly connected with the first or second end of the first frame unit, thereby allowing the first frame unit to contract and expand while remaining on the first plane;
- and
- a third piece comprising a third segment rotatably connected with the second extension of the first piece, and a fourth segment fixedly connected with the first or second end of the second frame unit, thereby allowing the second frame unit to contract and expand while remaining on the first plane.
A collapsible bed frame comprising:
- a first frame unit and a second frame unit disposed side by side;
- an inner lateral bar unit disposed between the first and second frame units;
- and
- two first connectors to connect the first frame unit, the second frame unit and the inner lateral bar unit;
- wherein each of the first frame unit, the second frame unit and the inner lateral bar unit has a first end and a second end;
- wherein each first connector comprises:
- a first piece comprising an affixing piece, a first extension at a first side of the affixing piece and a second extension at a second side of the affixing piece, wherein the affixing piece is formed with an elongated slot to expose at least a portion of the first or second end of the inner lateral bar unit, thereby allowing multiple spot welding or continuous welding through the elongated slot to enhance connection strength between the affixing piece and the inner lateral bar unit;
- a second piece rotatably connected with the first extension of the first piece, and fixedly connected with the first or second end of the first frame unit;
- and a third piece rotatably connected with the second extension of the first piece, and fixedly connected with the first or second end of the second frame unit,
- wherein the elongated slot is elongated in a longitudinal direction of the inner lateral bar unit.
