Abstract
Disclosed are connectors and collapsible bed frames. A collapsible bed frame includes lateral and longitudinal bar units. Between each of two adjacent lateral bar units, a first longitudinal bar unit is disposed at a first side of the collapsible bed frame and a second longitudinal bar unit is disposed at a second side of the collapsible bed frame. The first and second longitudinal bar units and the two adjacent lateral bar units are rotatably connected with each other by connectors that enable the collapsible bed frame to contract and expand while the lateral and longitudinal bar units are connected with each other.
Claims30
A collapsible bed frame comprising:
- a plurality of lateral bar units, each arranged substantially parallel to another, each having a first end and a second end, wherein the plurality of lateral bar units comprises a first outer lateral bar unit, a second outer lateral bar unit, and at least one inner lateral bar unit disposed between the first and second outer lateral bar units;
- a plurality of first longitudinal bar units and a plurality of second longitudinal bar units, wherein between each of two adjacent lateral bar units, a first longitudinal bar unit in the plurality of first longitudinal bar units is disposed at a first side of the collapsible bed frame and rotatably connected with the first ends of the two adjacent lateral bar units, and a second longitudinal bar unit in the plurality of second longitudinal bar units is disposed at a second side of the collapsible bed frame and rotatably connected with the second ends of the two adjacent lateral bar units;
- a plurality of first connectors, each comprising a first body and a first coupler rotatable with respect to the first body, wherein the first body is connected with the first or second end of a respective outer lateral bar unit in the first and second outer lateral bar units, and the first coupler is connected with an end of a corresponding first or second longitudinal bar unit;
- and
- a plurality of second connectors, each connected with the first or second end of a respective inner lateral bar unit in the at least one inner lateral bar unit and connected with ends of two adjacent longitudinal bar units in the plurality of first longitudinal bar units or in the plurality of second longitudinal bar units,
- wherein each second connector comprises a first piece fixedly coupled with the first or second end of the respective inner lateral bar, wherein the first piece is formed with a through-hole to receive the first or second end of the respective inner lateral bar unit, thereby increasing a strength of the connection between the first piece and the first or second end of the respective inner lateral bar unit;
- wherein one or more receptacles are formed or disposed at each bar unit in the plurality of lateral bar units, the plurality of first longitudinal bar units, and the plurality of second longitudinal bar units and configured to removably receive one or more supporting bar units.
