Patent ID: 8534427

Claim:
A movable desk, comprising: a top panel; at least one leg portion that includes a plurality of casters in a lower portion and rotatably supports the top panel through a top panel rotation shaft between a substantially horizontal in-use position and a substantially vertical storage position; and at least one brake mechanism that prevents movement of the movable desk when the top panel is in the in-use position, wherein the at least one brake mechanism includes: a cam that rotates in accordance with a rotation of the top panel; an elevation member that includes one end swingably connected to the cam and is moved downward in accordance with a rotation of the top panel when the top panel is rotated from the storage position to the in-use position, while being moved upward in accordance with a rotation of the top panel when the top panel is rotated from the in-use position to the storage position; a stopper portion that is swingably connected directly to the elevation member, is vertically moved in accordance with an upward and downward movement of the elevation member, and includes one end portion contacting a floor surface when the top panel is in the in-use position thereby to fix the at least one leg portion with respect to the floor surface; and a guide portion that abuts the stopper portion thereby to guide the vertical movement of the stopper portion and to bring the stopper portion into contact with a predetermined position of the floor surface; wherein the at least one leg portion includes: a leg pole having a portion supporting the top panel and a lower end contacting the floor surface and being obliquely arranged in such a manner that an upper end is positioned rearward of the lower end in a front-back direction of the movable desk; a leg support having a first end portion fixed to the leg pole and a second end portion contacting the floor surface; wherein the stopper portion includes a rod portion; wherein one of the plurality of casters includes a tubular portion through which the guide portion is insertable; wherein the guide portion includes a hollow portion which is cylindrically formed to receive the rod portion slidably in a vertical direction, the guide portion being configured to be joined with the caster by being inserted into the tubular portion of the caster in such a manner that the caster is rotatable; and wherein the brake mechanism is provided to the leg pole and is not provided to the second end portion of the leg support.
