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.

First claim

What is claimed is:

1. 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.

2. The collapsible bed frame of claim 1 , wherein between the respective outer lateral bar unit and its adjacent inner lateral bar unit:
each of the first and second longitudinal bar units comprises a first longitudinal segment unit and a second longitudinal segment unit rotatably connected with each other at one ends thereof, wherein the other end of the first longitudinal segment unit is connected with the first coupler of the corresponding first connector at the respective outer lateral bar unit, and the other end of the second longitudinal segment unit is connected with the adjacent inner lateral bar unit.

3. The collapsible bed frame of claim 2 , wherein the first body has a substantially cylindrical shape, and the first coupler comprises a first part rotatably coupled with the first body and a second part connected with the other end of the first longitudinal segment unit.

4. The collapsible bed frame of claim 3 , wherein the first part is formed with a first through-hole, wherein the first part of the first coupler is coupled with the first body by a first fastener through the first through-hole.

5. The collapsible bed frame of claim 3 , wherein the second part of the first coupler is formed with a second through-hole configured to couple with the other end of the first or second longitudinal segment unit.

6. The collapsible bed frame of claim 1 , wherein:
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 comprises an upper bar and a lower bar;
the upper bars of the plurality of lateral bar units, the plurality of first longitudinal bar units, and the plurality of second longitudinal bar units collectively form an upper frame of the collapsible bed frame; and
the lower bars of the plurality of lateral bar units, the plurality of first longitudinal bar units, and the plurality of second longitudinal bar units collectively form a lower frame of the collapsible bed frame.

7. The collapsible bed frame of claim 6 , wherein the first coupler comprises a first upper coupler disposed at an upper portion of the first body and a first lower coupler disposed at a lower portion of the first body, wherein the first upper coupler is connected with the upper bar of the corresponding first or second longitudinal bar unit, and the first lower coupler is connected with the lower bar of the corresponding first or second longitudinal bar unit.

8. The collapsible bed frame of claim 7 , wherein the first lower coupler comprises a protrusion facing downwardly with respect to the collapsible bed frame when the collapsible bed frame is in an expanded state.

9. The collapsible bed frame of claim 7 , wherein the first upper and lower couplers are coupled with the first body by one or more fasteners.

10. The collapsible bed frame of claim 6 , further comprising a plurality of vertical supporting bars disposed between the upper and lower frames, each having an upper end connected with the upper frame and a lower end connected with the lower frame.

11. 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 a second longitudinal bar unit in the plurality of second longitudinal bar units is disposed at a second side of the collapsible bed frame;
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 an adjacent longitudinal bar unit in the plurality of first and second longitudinal bar units; 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.

12. The collapsible bed frame of claim 11 , wherein between the respective outer lateral bar unit and its adjacent inner lateral bar unit:
each of the first and second longitudinal bar units comprises a first longitudinal segment unit and a second longitudinal
