Sit-up flexible protection beam

Abstract

The invention discloses a sit-up flexible protection beam, which comprises a U-shaped clamp element and flexible protection beams clamped at the two ends of the back part of the U-shaped clamp element; the back part of a front part opening of the U-shaped clamp element is closed; an inclination angle alpha between the flexible protection beams in the work state and the U-shaped clamping element is greater than or equal to 90 to 120 degrees; the flexible protection beam plane is positioned in a region beyond the range from the U-shaped clamp element and flexible protection beam clamping position to the back end of the U-shaped clamping element or the translated position at the back end of the U-shaped clamp element. The sit-up flexible protection beam can be formed by a flexible support frame and a flexible sleeve sleeving the outside of the flexible support frame. The sit-up flexible protection beam sit-up flexible protection beam is clamped on the edge of a table; the flexible surface realizes the large area contact with the chest of an infant or a teenager. The comfort of the chest of the teenager during the infant or teenager is ensured; the learning fatigue is relieved; the sit-up is ensured without influencing the chest development of the infant and teenager; the multiple purposes are achieved by one operation.

Description

technical field [0001] The invention relates to school supplies for students, and is an invention about a flexible guard for sitting upright. Background technique [0002] At present, the reading and writing posture error rate of young children and adolescents in our country is as high as 85%. Although we can make them hold the pen in the correct posture through the positive posture pen, and make their sight distance standard through the adjustable seat, but due to long-term study fatigue or misreading As for the habit of writing posture, most students still lie on the table to read and write, which causes two problems: 1. The eyes are too close to the book; 2. The chest is pressed against the hard edge of the table. If the eyes are too close to the books, it will inevitably lead to the myopia of most children and adolescents, and the pressure of the chest on the hard table will affect the chest development of children, especially girls in the growth and development stage. ...

[0003] There are some technical solutions for children to read and write on their stomachs, which can indeed prevent children and adolescents from reading and writing on their desks, but they do not fully consider the comfort of use, restricting the freedom of activities of children and adolescents or still being hard The material is in contact with their chest, which is often not welcomed by children, so it is difficult to really play the role of positive posture
