Description

U-curve electric bed

本發明係與床有關，特別是有關於一種U型曲線電動床。The present invention is related to the bed, in particular to a U-curve electric bed.

人每天有1/3左右的時間位於床上，通常床的結構都是在平坦的床上設置較軟的床墊，使用者再直接躺於上方休息。然而，有些使用者在半躺的姿勢閱讀書籍、使用3D產品時，其腰部、背部處於受力不正常之彎曲狀態，日積月累，亦造成椎間盤突出、筋骨不適、肌肉僵硬等問題。People spend about 1/3 of the time on the bed every day. Usually, the structure of the bed is to set a relatively soft mattress on a flat bed, and then the user lies directly on the top to rest. However, when some users read books and use 3D products in a half-recumbent position, their waists and backs are in an abnormally curved state. Over time, it also causes problems such as disc herniation, muscle and bone discomfort, and muscle stiffness.

又，抬腿可舒緩腿部痠痛、水腫、促進血液循環等好處。然而，一般的床墊都成平坦狀，當使用者欲抬腿時，需使上半身平躺於床墊上，而下半身的腿部與上半身略呈90度並靠於牆壁上，造成抬腳的不便。In addition, leg lifting can relieve leg pain, edema, and promote blood circulation. However, the general mattresses are flat. When users want to lift their legs, they need to make the upper body lie flat on the mattress, while the legs of the lower body are slightly 90 degrees from the upper body and lean against the wall, causing the feet to lift. inconvenient.

因此，有必要提供一種新穎且具有進步性之U型曲線電動床，以解決上述之問題。Therefore, it is necessary to provide a novel and progressive U-shaped electric bed to solve the above problems.
