Abstract
A furniture device includes: a movable device; a height adjustment mechanism operably coupled with the movable device and configured for supporting the movable device in a plurality of positions including a lower position and an upper position, the height adjustment mechanism including: a ratchet defining a plurality of stations including a lower station and an upper station corresponding respectively to the upper position and the lower position; a rod configured for selectively engaging the plurality of stations; and a rod return device configured for pivoting and thereby for returning the rod to the upper station.
Claims9
A furniture device, comprising:
- a movable device;
- a height adjustment mechanism operably coupled with the movable device and configured for supporting the movable device in a plurality of positions including a lower position and an upper position, the height adjustment mechanism including:
- a ratchet defining a plurality of stations including a lower station and an upper station corresponding respectively to the upper position and the lower position, the upper station being located above the lower station, the movable device forming the ratchet, the ratchet including a plurality of teeth which define the plurality of stations therebetween;
- a rod configured for selectively engaging the plurality of stations;
- and
- a rod return device configured for pivoting and thereby for returning the rod to the upper station;
- and
- a base, the rod and the rod return device each being coupled with the base, the base defining a groove which has an angular configuration, the rod including an end which is configured for sliding within the groove.
A height adjustment mechanism of a furniture device, the furniture device including a movable device, the height adjustment mechanism being operably coupled with the movable device and configured for supporting the movable device in a plurality of positions including a lower position and an upper position, the height adjustment mechanism comprising:
- a ratchet defining a plurality of stations including a lower station and an upper station corresponding respectively to the upper position and the lower position, the upper station being located above the lower station, the movable device forming the ratchet, the ratchet including a plurality of teeth which define the plurality of stations therebetween;
- a rod configured for selectively engaging the plurality of stations;
- and
- a rod return device configured for pivoting and thereby for returning the rod to the upper station, the rod and the rod return device each being configured for being coupled with a base of the furniture device, the rod including an end which is configured for sliding within a groove which the base defines and which has an angular configuration.
A method of using a furniture device, the method comprising the steps of:
- providing the furniture device which includes a movable device and a height adjustment mechanism operably coupled with the movable device and configured for supporting the movable device in a plurality of positions including a lower position and an upper position, the height adjustment mechanism including a ratchet, a rod, and a rod return device, the ratchet defining a plurality of stations including a lower station and an upper station corresponding respectively to the upper position and the lower position, the upper station being located above the lower station, the movable device forming the ratchet, the ratchet including a plurality of teeth which define the plurality of stations therebetween, the furniture device further including a base, the rod and the rod return device each being coupled with the base, the base defining a groove which has an angular configuration, the rod including an end which is configured for sliding within the groove;
- engaging selectively, by the rod, the plurality of stations;
- and
- pivoting the rod return device and thereby returning the rod to the upper station.
