Abstract
A width-adjustable foldable bed includes a main bed frame unit that includes a first bed frame subunit and a second bed frame subunit. The second bed frame subunit is pivotable relative to the first bed frame subunit to fold the main bed frame unit from a bed flat state, where the first bed frame subunit and the second bed frame subunit are arranged in a lengthwise direction, to a bed folded state, where the first bed frame subunit is stacked on top of the second bed frame subunit. Two lateral bed frame units are connected to two lateral sides of the first bed frame subunit and the second bed frame subunit. A backrest actuating device is connected to the first bed frame subunit, and is operable for driving the first bed frame subunit to switch between a first flat state and a first bent state.
Claims9
A width-adjustable foldable bed comprising:
- a support unit;
- a main bed frame unit that is disposed on said support unit, and that includes a first bed frame subunit and a second bed frame subunit connected to said first bed frame subunit, said second bed frame subunit being pivotable relative to said first bed frame subunit to fold said main bed frame unit from a bed flat state, where said first bed frame subunit and said second bed frame subunit are arranged in a lengthwise direction, to a bed folded state, where said first bed frame subunit is stacked on top of said second bed frame subunit;
- two lateral bed frame units that are respectively and detachably connected to two lateral sides of said first bed frame subunit, that are respectively and detachably connected to two lateral sides of said second bed frame subunit, and that are opposite to each other in a widthwise direction perpendicular to the lengthwise direction;
- and
- a driving unit that includes a backrest actuating device connected to said first bed frame subunit, and that is operable for driving said first bed frame subunit to switch between a first flat state and a first bent state;
- wherein said first bed frame subunit includes a main backrest frame and a first main fixing frame pivotally connected to said main backrest frame;
- wherein said second bed frame subunit includes
- a second main fixing frame that is pivotally connected to said first main fixing frame,
- a main leg frame that is pivotally connected to said second main fixing frame, and
- a main foot frame that is pivotally connected to said main leg frame;
- and
- wherein each of said lateral bed frame units includes
- a lateral backrest frame that is detachably connected to said main backrest frame,
- a first lateral fixing frame that is detachably connected to said first main fixing frame,
- a second lateral fixing frame that is detachably connected to said second main fixing frame,
- a lateral leg frame that is detachably connected to said main leg frame, and
- a lateral foot frame that is detachably connected to said main foot frame.
