Description

Telescopic chair

This creation department is about a telescopic function chair, especially an adjustable chair back angle, front and rear telescopic, suitable for students of all heights to recline on the lunch break with a telescopic function chair.

At present, when students study, write, or draw pictures at school, they use desks and chairs to enable students or students to read, write, and draw in the correct posture. However, the height of the chair and the depth of the back are generally fixed, but the student's body is not fixed. Although there is a chair designed to match the student's body, the chair is set to a shallower height between the height of the chair and the back of the chair to provide students with more comfort and safety. However, such a chair that fits the student cannot be fully used by the student. Because the student's body will grow taller and smaller, the chair that was originally suitable will become more and more unsuitable.

Furthermore, please refer to the picture shown in Figure 19, which is a schematic diagram of the current general student chair (A1). At present, in general, during lunch breaks, in addition to lunch, the most important thing is to be able to take a nap comfortably. However, due to the limited space in the classroom, it is unlikely that there will be extra space for the students to place a mattress that can be placed flat. Therefore, you can only sit on your own chair and doze off. However, it is quite uncomfortable to take a nap during the nap, especially after taking a nap after eating lunch, it is easy to oppress the abdomen, which leads to discomfort in the stomach. As well as causing numbness in students' hands and feet. Moreover, the schoolbags currently carried by students can be hung on the back of the chair, while books, stationery, tableware, etc. can only be placed in the drawer of the table. However, the disadvantage is that the bulky school supplies cannot be placed in the drawer, which is very inconvenient. Also, the bottom of the student chair is hollow at the moment. Although it can accommodate larger school supplies, it is limited by the larger school supplies when moving student desks.

However, in order to enable students to have better sleep quality during lunch breaks, the research and development of the patent case No. M347873 of the Republic of China, "The structure of a student chair with a reclining sleep," includes a seat and a chair. The back seat and the positioning bolt are formed; wherein: the seat is composed of a seat plate, a front pillar, a rear pillar, a protruding pillar, a storage panel, a fitting block and a track, and two rear pillars are arranged behind the seat panel, outside the rear pillar A positioning hole is arranged below, and a protruding column is arranged on the outer side of the rear pillar. A storage panel is arranged under the seat plate, and a fitting block is arranged on the left and right sides between the seat plate and the storage panel, and the fitting block is provided with a fitting. a hole, and the fitting block is engaged with the rear pillar; the back of the chair is composed of a backing plate, a supporting column and a sliding groove, and a supporting column is arranged on each of the left and right sides of the supporting plate, and a perforation is arranged under the supporting column and supported A sliding slot is arranged on the inner side of the column; the positioning bolt is composed of a card strip, a blocking piece, a fixing piece, a spring and a screw, and one end of the strip is provided with a blocking piece, and the blocking piece is convexly provided with a positioning end, and the blocking piece is further provided with a positioning end. One side is provided with a blocking piece, and another fixed piece is provided on the positioning end.

In summary, the conventional system has the following deficiencies:

1. At present, when students are studying in the classroom, they use the student chair (A1) as in the 19th figure, but when the student takes a nap on the student chair (A1) after eating lunch, it is easy to oppress the abdomen. , which in turn causes discomfort in the stomach. And, it is easy to cause the phenomenon of numbness of students' hands and feet.

2. It is known that the structure of a student chair with a reclining sleep mainly reveals a tiltable back structure. However, students still have to sit in a resting position, so there is still a tendency to cause numbness in students' hands and feet. Moreover, the conventional "student chair structure with lying reclining and sleeping" cannot adjust the length suitable for the ride for students of different heights, so it is less practical.

Therefore, in order to improve the current student's sleep on the student chair (A1) as shown in the nineteenth figure after eating lunch, it is easy to oppress the abdomen, which leads to discomfort in the stomach. And, it is easy to cause the phenomenon of numbness of students' hands and feet. In addition, in order to improve the conventional structure of the student chair with reclining and reclining, the student must still be seated while resting, so there is still a tendency to cause numbness in the hands and feet of the student. And it is not possible to adjust the length of the ride for students of different heights. Therefore, the creator further develops a telescopic function chair, which comprises: a chair body, the chair system is composed of a plurality of brackets, and the chair body comprises a fixing plate and a bottom plate opposite to the fixing plate, the fixing The plate and the bottom plate form an accommodating space, the chair body is provided with a first moving member and a second moving member on opposite sides; a first telescopic chair set, the first telescopic chair set includes a third movement And the third moving member moves in the first moving member, the first telescoping chair set includes a first side plate and is relatively pivoted to serve as a first seat plate; a second telescoping chair set, The second telescopic chair set includes a fourth moving member, and the fourth moving member moves in the second moving member.
