Abstract
Height adjustable angled desks are disclosed herein. An example height adjustable table includes three legs, each of the three legs including an upper section, a lower section, and an actuator; a connection system to couple the three legs; a height adjust system including drive system; a first gearbox coupled to the drive system; second gearboxes coupled to respective ones of the actuators, the first gearbox and the second gearboxes to change a transmission direction; and transmission shafts connected to the drive system and to the first and second gearboxes; and wherein the drive system is configured to drive the transmission shafts to drive the legs together to rise and fall, and wherein the drive system includes a motor, a worm connected to the motor, and a worm wheel engaged with the worm.
Claims21
A height adjustable table, comprising:
- three legs, each of the three legs including an upper section, a lower section, and an actuator;
- a connection system to couple the three legs;
- and
- a height adjustment system including:
- a drive system including a drive system housing, one motor, a worm connected to the motor, a worm wheel engaged with the worm, and an output shaft, the drive system to drive the output shaft;
- a first gearbox coupled to the drive system, the first gearbox to convert rotation of the output shaft in a first horizontal transmission direction to rotation of an interconnection shaft in a second horizontal transmission direction, the first gearbox including a gearbox housing attached to the drive system housing, the output shaft extending through the first gearbox;
- second gearboxes separate from the first gearbox, the second gearboxes coupled to respective ones of the actuators, each second gearbox to correspond to a respective leg, each second gearbox to change one of the first horizontal transmission direction or the second horizontal transmission direction to a vertical transmission direction;
- and
- transmission shafts, each one of the transmission shafts connected to one of the output shaft or the interconnection shaft, and one of the second gearboxes,
- wherein the drive system is configured to drive the transmission shafts to drive the legs together to rise and fall.
A system to adjust a height of a desk, the system comprising:
- three actuators positioned vertically relative to a ground, each of the actuators including a portion of a telescoping leg, a threaded nut coupled to the portion of the telescoping leg, and a threaded rod rotatably coupled to the threaded nut and extending from the portion of the telescoping leg;
- three leg gearboxes, each leg gearbox coupled to a respective actuator, wherein the leg gearboxes are configured to change respective horizontal transmission directions to a vertical transmission direction;
- a drive system including a drive system housing, one motor, a worm gear assembly, and an output shaft;
- an interconnection gearbox configured to convert rotation of the output shaft in a first one of the horizontal transmission directions to rotation of an interconnection shaft in a second one of the horizontal transmission directions, the interconnection gearbox including an interconnection gearbox housing attached to the drive system housing, the output shaft extending through the interconnection gearbox;
- and
- transmission shafts rotatably coupled to the drive system, the leg gearboxes, and the interconnection gearbox,
- wherein the drive system is configured to drive the transmission shafts to drive, collectively, the threaded rods to rotate, the rotation of the threaded rods to cause the threaded rods to slide relative to the threaded nuts to raise or lower the threaded rods.
