    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a height adjustable table, and more particularly to an automatic continuously height adjustable table.
  • 2. Description of the Prior Art
  • From the ergonomic point of view, a person who often keeps sitting posture for a long time is likely to be hunchbacked, if the table and chair he/she sits are improperly designed and or the height is incorrect, his head will lean forward naturally, resulting in the muscle tone imbalance at the front body and the rear and causing the spinal pressure increase. If some special actions are endlessly repeated for a long time during work, it will cause muscle strain, muscle compression, nerve compression, tendon injury and ligament sprain at the shoulder, the neck, the upper limbs, and the back. When the injury seriousness accumulates to a certain level, it will cause the pain, the ankylosis and the numbly symptoms at the shoulder, the neck, the upper limbs and the back etc, that is called repetitive strain injury. Meanwhile, with the increase of the spinal pressure, it is likely to cause work-related musculoskeletal disorders. Additionally, long-time sitting posture will also block the returning flow of the venous blood, thus causing the flood to subside to the shanks. Consequently, it will cause the foot edema, varicosity and the like.
  • To avoid the abovementioned problems, a height adjustable table was developed on the market. The height adjustable table comprises a load board, at least one kingpost and a control panel. A linear actuator inside the kingpost is dynamically connected to the kingpost for enabling the kingpost to carry out linear extension. One end of the kingpost is coaxially assembled with the load board and the control plane is electrically connected to the linear actuator. The control panel is utilized to turn on/off the linear actuator, so as to make the linear actuator rotate clockwise or counterclockwise, and accordingly enabling the kingpost to carry out the linear extension. Thereby, the load board will rise or lower along with the kingpost. However, it still has the following problems:
  • The users must utilize the control panel to control the extension of the kingpost. However, the users are often too busy to forget the function or they feel too troublesome to use the function, so they rarely use the function, causing the failure of the function. Consequently, how to make the height adjustable table automatically continuously rise and lower and compel the user to change his sitting posture and reduce the improper pressures and the load on the body to avoid of the nerves, muscles, skeletons and circulation disorders will be the key point for the recent research and development.
  • The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
    • SUMMARY OF THE INVENTION
  • The primary objective of the present invention is to provide an automatic continuously height adjustable table which can compel the user to move about, thus reducing the improper pressure and the load on his body.
  • To achieve the abovementioned objective, the automatic continuously height adjustable table of the present invention comprises a load board, at least one kingpost and a controller. The controller includes a control panel, a time unit, a count unit and a storage unit. The controller is utilized to turn on/off the linear actuator according to the sitting time parameter and the standing time parameter which are set by the time unit, so as to make the linear actuator rotate clockwise or counterclockwise and accordingly enabling the kingpost to carry out the linear extension according to the sitting height parameter and the standing height parameter which are set by the count unit. Thus compelling the user to change his postures, and consequently reducing the improper pressure and load on the body and avoiding the nerve, muscle skeleton fatigue and the circulation disorder.
