  • the bed according to the present invention further includes a weight sensor and a sleeping recognition sensor.
  • the weight sensor recognizes a weight of the user, and then the tilting angle of the bed may be controlled.
  • the tilting angle of the bed proposed in the present invention can be controlled according to the weight of the user. Further, it is determined by using the sleeping recognition sensor whether the user is sleeping. If the user substantially does not sleep, the bed proposed in the present invention may not perform the operation rhythm. Further, if the weight sensor detects a user with a weight within an error range of the set weight, the controller may automatically operate. If the weight sensed by the weight sensor is out of the error range of the set weight, the controller automatically stops the operation of the operation unit.
  • the present invention may be set to have a different rhythm according to information on the user's health input by the user.
  • the present invention is set to have different pieces of information on the health with relation to obesity, malnutrition, hypertension, hypotension, diseases related to bones (arthritis and various kinds of disk), varicose veins, poor blood circulation, aging of the skin and the like.
  • the user may set the operation rhythm by selecting one of plural operation rhythms, or set an optimal operation rhythm through the controller by using information stored in storing space.
  • the tilting angle may be set in a range of certain angles as well as in the range of angles of -10° ⁇ 10°.
  • the present invention may be set to have an optimal operation rhythm according to gender, age, and occupation.
  • the bed may have a different motor depending on its size. That is, in the case that the bed has a large size, a motor with a large capacity may be used. In the case that the bed has a small size, a motor with a small capacity may be used. Also, a geared motor of a low noise which has a separate noise preventing unit may be used. In order to reduce noise in mechanical parts, a mechanical structure may be disposed in a soundproof box made from a soundproof material. Various sorts of motors as well as the above-mentioned motor may be used. That is, a motor such as a hydraulic type motor using oil or water and a pneumatic type motor may be used. In order to save electric charges and to prevent overload or mechanical troubles, a control unit for isolating electricity and a sensor for detecting the overload or the mechanical problems may be attached to the motor.
  • the above-mentioned operation of the bed may be performed according to the user's setting. That is, the bed may be applied as a bed for beauty. Moreover, it is possible to differently adjust a time until the bed is tilted and arrives at a set angle. That is, in the case that the set tilting angle is 10°, it is possible to set the time to five seconds, ten seconds, and the like according to the user.
  • the control unit of the bed In the case that a new signal is input from the user before a lapse of the set deep sleep time, the control unit of the bed according to the present invention counts again a time from a beginning until the user enters the deep sleep.
  • the sleeping recognition sensor is mounted on an upper portion of the bed, and identifies a pupil of the user and a movement of the user, thereby determining whether the user is sleeping.
  • the present invention can classify the sleep state into various states such as the deep sleep state, a provisional sleep state, and the like.
  • the bed may be set to operate with a different operation rhythm.
  • the bed may be set to operate a different operation rhythm according to the present invention. That is, at midnight, i.e. one a.m. to three a.m., when the user is in the deep sleep state, or at dawn, the bed may be set to operate with different operation rhythms.
  • the bed may be classified into plural parts, and a tilting angle or a tilting time may be differently set to correspond to each part. That is, according to the above description, it is described that the bed is configured to have one piece and be entirely tilted at a predetermined angle.
  • the present invention is not limited thereto. That is, the bed is divided into two parts, and then different operation rhythms may be set to the two parts respectively in order for the two parts to individually operate. For example, only one of the two parts may be set to operate at a predetermined angle. To do this, a separate operation unit is provided to each part of the bed.
  • the bed is disposed in a state of being tilted at a predetermined angle. That is, when the bed is initially disposed to be in close contact with a wall in parallel with the room floor, the bed cannot be tilted at the predetermined angle. Accordingly, the bed is initially disposed to be tilted at the predetermined angle, and then is moved in parallel with the floor when the weight sensor recognizes the user. Then, the bed performs a predetermined operation under a control of the controller.
  • the functional bed according to the present invention has various advantages for health.
  • the functional bed 1 of the present invention uses gravity during the sleeping time, so as to prevent the drooping of the skin and to delay the aging of the human body.
  • a woman may use a functional pack which is hung on her ears and pulls skin upward.
  • the action of gravity is greatly reduced while she lies in the functional bed 1 for the sleeping time or the waking time.
  • it is possible to delay or prevent the aging of the skin including the drooping of the skin and a generation of wrinkles such as grabellar frown lines, nasolatibial folds, crow's feet, kissing lines and marionette lines.
  • the bed of the present invention provides an improvement of blood circulation in patients with diseases related to varicose veins which are caused by user's weight and gravity in living and vascular diseases such as hypertension and hypotension.
  • the skin of the user is subjected to a pressure of gravity which is less than that while standing, and the body of the user is tilted in such a manner that his/her head is located to be lower than his/her legs. Accordingly, the user is stable and comfortable rather than sleeping in a horizontal state.
  • the bed may be tilted at a predetermined angle so that the user's head is higher than his/her legs, according to circumstance.
  • the bed helps the user have a good sleep, fatigue which the user's skin feels can be reduced, thereby preventing wrinkles, melisma and the like.
  • Elasticity is provided to pores, thereby preventing growth of the pores.
  • the present invention has advantages in that the action of gravity is minimized in a sleeping state in which the user's face has no tension so that wrinkles on the face are stably and clearly flattened or removed while the elasticity of the skin increases.
