Abstract
An adjustable desk includes a planar desktop and adjustable brackets that are coupled to a vertical wall with magnets. The adjustable desk has a horizontal position where the desktop is horizontal and a retracted position where the desktop is rotated downward.
Claims20
An adjustable desk comprising:
- a first bracket having a first rotational elongated member, a first non-rotational elongated member, a first magnet coupled to the first non-rotational elongated vertical member, and a first hinge coupled to an inner end of the first rotational elongated member, an upper end of the first non-rotational elongated vertical member, and a first support member coupled between the first rotational elongated member and the first non-rotational elongated vertical member;
- a second bracket having a second rotational elongated member, a second non-rotational elongated vertical member, a second magnet coupled to the second non-rotational elongated vertical member, a second hinge coupled to an inner end of the second rotational elongated member and an upper end of the second non-rotational elongated vertical member, and a second support member coupled between the second rotational elongated member and the second non-rotational elongated vertical member;
- and
- a planar desktop rigidly coupled to the first rotational elongated member and the second rotational elongated member;
- wherein the first magnet holds the first non-rotational elongated vertical member against a vertical wall, the second magnet holds the second non-rotational elongated vertical member against the vertical wall, the first support member and the second support member have an extended position which holds the desktop and the first rotational elongated member and the second rotational elongated member in a horizontal position and the first support member and the second support member have a retracted position where the desktop and the first rotational elongated member and the second rotational elongated member in a downward rotated position and a slide force (Fslide)=a magnetic force (Fmagnetic)×a coefficient of friction (CF) of the first magnet and the second magnet against the metal bar supports the weight of the first bracket, the second bracket, and the planar desktop.
