Description

  The present invention relates to a learning desk and a chair with a sitting posture detection function, and more particularly to a chair with a sitting posture detection function capable of monitoring a sitting posture when a child learns at the learning desk.

  When a child learns at a study desk, the sitting posture is often poor. For example, the user may sit on the front side of the seat portion of the chair, or may take a posture with a bad forward leaning posture or a backward leaning posture. If such a bad posture is continued, the balance of the body may be worsened, the eyes may be worsened, and further, adverse effects such as distracting concentration in study will occur.

In addition, just like students are willing to sit and study in front of their desks, learning desks with boards with various character pictures and maps written on them quickly get bored and students sit in front of their desks. There was a problem of not learning.

  In a chair with a seating posture detection function that can monitor the seating posture that the child learns at the learning desk, the learning time can be grasped based on the child's sitting posture, and based on this, the usage time of games etc. is automatically It is an object of the present invention to provide a learning desk that can be accumulated, and that can be expected to increase the time for children to sit and study in front of the desk.

  In order to solve the problems ahead, the present invention provides a contact detection sensor for a seated person at a predetermined position of the rear part of the seat part or the backrest part or both of the rear part and the backrest part of the seat part. A learning desk and a chair with a seating posture detection function capable of monitoring whether the back or both the back part and the back part are in contact state or non-contact state with respect to the contact detection sensor.

  When the seated person's waist or back is in contact with the contact sensor, the time is accumulated, and when it is in the non-contact state, the game play time in which time is not accumulated or the counter of the breeding game is added.

  It is preferable that an alarm is generated when the seated person's waist or back or both the waist and back are separated from the contact sensor for a certain time.

  More specifically, the contact detection sensor is preferably a pressure sensor or a proximity sensor. It is preferable to use any one or a combination of light emission by a light emitter disposed at a predetermined position, sound generation by a speaker, or the like as the alarm and the means for issuing the alarm.

  An image recognition device is provided on the main body of the learning desk, and a sensor for detecting contact with the seated person is provided at a predetermined position of both the rear part and the back part of the sitting seat part or the rear part and the back part of the seat part. Recognition or non-recognition of human body position (for example, the position of the head) and whether the seated person's waist or back or both the waist and back are in contact or non-contact with the touch sensor. Therefore, it is possible to monitor whether or not the child is in the correct sitting position when the child learns at the learning desk.

  If a bad sitting posture continues for a certain period of time, an alarm will be issued, so that the seated person can be encouraged to return to the correct sitting posture, and this will cause worsening of the physical balance of the growing child, fatigue and decreased vision Can be prevented.

  With a counter function that adds game play time according to the elapsed time in maintaining a good sitting posture, or a counter as a life source of a breeding game, for example, children will be happy to sit at the desk It can be expected to increase learning time.

  Embodiments of the present invention will be described in more detail with reference to the accompanying drawings. 1 to 3 show an example in which the present invention is applied to a learning chair, in which T is a seated person, 1 is a chair, 2 is a learning desk, 3 is a seat, 4 is a backrest, and 5 is a backrest. A touch sensor 6 and a work sensor 6 are shown.

  The chair 1 of the present invention is provided with a contact detection sensor 5 for the seated person T at a predetermined position of the rear part of the seat part 3 or the backrest part 4 or both of the rear part of the seat part 3 and the backrest part 4. Alternatively, whether the back or both the buttocks and the back are in a contact state or a non-contact state with respect to the contact detection sensor 5 is monitored. Here, the contact detection sensor 5 provided on the seat portion 3 is indicated as 5A, and the contact detection sensor 5 provided on the backrest portion 4 is indicated as 5B.

  Usually, the seat 3 and the backrest 4 of the chair 1 are set so that the seating position of the seated person T in contact with the buttocks and the back is the correct sitting posture. When this correct seating posture is taken, a contact detection sensor 5A is provided at the rear of the seat 3 where the seated person's T's buttocks come into contact, and the contact detection sensor 5B is placed at an appropriate position on the backrest 4 where the back of the seated person T comes into contact. Provided. Here, as the touch sensor 5, a pressure sensor or a proximity sensor is used, but other optical sensors may be used.

  The contact detection sensor 5 is controlled by a control device (not shown) attached to an appropriate position of the chair 1 and recognizes that a predetermined seating position of the seated person T is in contact, The normal posture detection signal is continuously sent to the control device. While the normal posture detection signal is generated, it is recognized that the seated person T maintains the correct sitting posture. When the buttocks or back of the seated person T moves away from the contact detection sensor 5 for a certain time, the normal posture detection signal is interrupted, so that the control device judges it and issues an alarm to prompt the user to return to the correct seating posture. It is. Here, as the alarm and the means for issuing the alarm, any one of vibrations by a vibrating body provided in a chair, light emission by a light emitting body disposed at a predetermined position, sound generation by a speaker (both not shown), or a combination thereof is used. Inform the seated person T. In addition, although the said control apparatus, the contact detection sensor 5, and the means to issue an alarm are made to supply electric power with the solar cell (not shown) provided in appropriate places, such as the back surface of the backrest part 4 of the chair 1, You may make it supply electric power from a primary battery, a secondary battery, or a commercial power source.

  Even when the seated person T moves away from the chair 1, if the contact detection sensor 5 is still driven, it will misrecognize that excessive power is consumed or a bad sitting posture is maintained. Therefore, a work detection sensor 6 for detecting that the hand of the seated person T is located on the top board 7 of the learning desk 2 and is working is provided at a suitable position such as the front end of the top board 7. It is desirable to start monitoring by the touch sensor 5 when the sensor 6 is activated.

  FIG. 1 shows a situation where a seated person T is sitting on the chair 1 in a correct posture and learning. In this case, it is detected by the work detection sensor 6 that the hand is located on the top plate 7, and the control device is operated, and the contact detection sensor 5A of the seat 3 contacts the buttocks of the seated person T. And the contact detection sensor 5B of the backrest part 4 detects that the back of the seated person T is in contact. The outputs from both the contact detection sensors 5A and 5B are input to an AND circuit in the control device. When both the contact detection sensors 5A and 5B output the normal posture detection signal, the H signal is output and the seated person is seated. The control device recognizes that T is the correct sitting posture.

  FIG. 2 shows a case where the seated person T sits in the front part of the seat part 3 of the chair 1 and has a bad sitting posture in which both the buttocks and the back are separated from the contact detection sensors 5A and 5B. In this case, since the outputs from both the contact detection sensors 5A and 5B are 0, the AND circuit outputs an L signal, the control device recognizes that the seated person T is in a bad sitting posture, and this state is constant. If it lasts for a period of time, an alarm is issued by the alarm means.

  FIG. 3 shows a situation where the seated person T is learning while sitting on the chair 1 in a forward leaning posture. In this case, the contact detection sensor 5A outputs a normal posture detection signal because the buttocks of the seated person T are in contact, but the output of the contact detection sensor 5B is 0 because the back of the seated person T is separated. Therefore, the AND circuit outputs an L signal, the control device recognizes that the seated person T is in a bad sitting posture, and if this state continues for a certain period of time, the alarm means issues an alarm.

  Further, even if the same sitting posture shown in FIG. 1 is maintained for a long time, it causes fatigue. Therefore, if the AND circuit continues to output the H signal for a certain time, the control device sends a signal to the alarm means and takes a break. It is also desirable to issue an alarm prompting

  In the present embodiment, the contact detection sensors 5 are provided on both the seat 3 and the backrest 4 of the chair 1, but at least one of them can be provided with a minimum seating posture detection function. When the contact detection sensor 5 is provided on one of the seat portion 3 and the backrest portion 4, it is more effective to provide the contact detection sensor 5 on the backrest portion 4.
