Description

Desk and chair integrated writing desk

Technical Field

The invention relates to the field of learning and office tools, in particular to a desk and chair integrated writing desk convenient for learning and working.

Background

Currently, the known writing tool is composed of a chair and a table which are independent of each other. The inherent structural defects of the table and the chair cannot avoid causing health hidden trouble to long-term users. For example, the major contributors to myopia, cervical, spinal and lumbar compression deformation, and the like. For this reason, a number of improved tables and chairs have appeared in the market in recent years, and these improvements have achieved some beneficial results. However, these improvements are only very modest in terms of the traditional so-called correct writing sitting posture concept. For example, existing products are all pursuing a sitting posture when the user writes, namely three 90 degrees: 1. the body is at a 90 degree angle to the thigh; 2. the thigh and the shank form an angle of 90 degrees; 3. the lower leg is at a 90 degree angle to the foot. Thus, these improvements are only more comfortable when at three 90 degrees than when previously at three 90 degrees, but do not guarantee that the user will always maintain three 90 degrees without leaning forward while writing for a long period of time. Moreover, three 90 degree sitting postures still cause great hidden trouble to human health, and the improvement does not overcome the fundamental structural defects of the traditional desk and chair for writing, but only has a little progress in terms of quantity.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention provides a desk and chair integrated writing desk. The desk and chair integrated writing desk provides a brand new writing posture concept, namely sitting up writing, and provides a powerful challenge for the traditional sitting up writing concept. The user leans back on the upper body, the waist, the back and the neck of the human body can be supported, the gravity center of the upper body of the human body is positioned behind the hip pivot, and the upper body and the head can not lean forward in a proper state, so that the human eyes and the tabletop can keep a proper distance all the time.

The technical scheme adopted for solving the technical problems is as follows: the support part A of the learning support with adjustable desktop position and angle is arranged on one side of the seat and is connected with the seat. The learning support capable of adjusting the position and the angle of the desktop at least has the function of normal writing; the seat is a seat with a backrest and comprises a fixed backrest and an adjustable backrest. The person sits on the seat in a lying way, and the relative position and angle of the desk top of the learning support which is connected with the seat and can adjust the position and angle of the desk top are adjusted, so that the person is in a comfortable lying and sitting writing posture.

The invention is further provided with: the seat is a seat with a backrest, and the sofa seat is one of the seats.

The invention is further provided with: one side of the seat is provided with an elbow support component A, the other side is provided with an elbow support component B, and the elbow support can be adjusted in height. The elbow rest is used for supporting arms which hang out of the tabletop when the human body leans backwards. One of the differences between the elbow rests and the armrests is that the elbow rests can lift the arms to a comfortable writing position.

The invention is further provided with: the upper end of the backrest on the chair is provided with a neck support which can adjust the up-down and front-back positions. So as to be suitable for users with different heights.

The invention is further provided with: the waist pillow is arranged at the joint of the backrest and the sitting surface and is used for supporting the waist when the upper body of the human body leans backwards.

The invention is further provided with: the learning support capable of adjusting the position and the angle of the desktop comprises a supporting part A, a cross arm part, a desktop part and a supporting part B. One end of the supporting component A is connected with one side of the seat, the other end of the supporting component A is connected with one end of the cross arm component, the middle part of the cross arm component is connected with the desktop component, one end of the supporting component B is connected with the other side of the seat, the other end of the cross arm component and the other end of the supporting component B are of an opening and closing structure, and in the working state, the other end of the cross arm component and the other end of the supporting component B are of a closed connection state, and at the moment, the learning support with adjustable desktop position and angle and the seat form a closed structure. When the cross arm part is in a non-working state, the cross arm part can horizontally rotate by taking the supporting part A as a fulcrum, and the other end of the cross arm part and the other end of the supporting part B are in an open state, so that people can enter and exit.

The invention is further provided with: the supporting component A comprises a mounting seat A, a supporting rod A and a locking device A. The support rod A is sleeved with the mounting seat A, can axially move relative to the mounting seat A, and is connected with the mounting seat A to adjust and fix the axial relative position of the support rod A and the mounting seat A.

The invention is further provided with: the cross arm component comprises a connecting piece A, a locking device D, a cross arm, a cantilever, a sliding block and a locking device E. One end of the cross arm is hinged to the upper end of the supporting rod A through a connecting piece A, and the cross arm part can move up and down along with the supporting rod A and can also rotate horizontally around the supporting rod A. The connecting piece A is provided with a locking device D for adjusting and fixing the rotating position of the cross arm in the connecting piece A. The middle part of the cross arm is provided with a cantilever, the sliding block is sleeved on the cantilever and can axially move along the cantilever, and the locking device E is arranged on the sliding block and is used for adjusting and fixing the relative position of the sliding block and the cantilever.

The invention is further provided with: the desktop component comprises a panel, a reading frame and a magnetic bar. The upper surface of the panel is made of magnetized materials or iron materials capable of absorbing magnets, and the surface of the panel is provided with movable magnetic barrier strips so as to prevent books from sliding downwards when the tabletop is in an inclined state; the reading frame is arranged at the front end of the panel; the lower part of the panel is connected with the sliding block in the cross arm part, and the panel can axially displace along the cantilever along with the sliding block.

The invention is further provided with: the supporting component B has the same principle and structure as the supporting component A.

The invention is further provided with: the lower end of the seat is provided with a footstool. The footstool can be height-adjustable so as to adapt to people with different heights for convenient use.

The beneficial effects of the invention are as follows: the upward sitting posture writing mode is a brand new writing mode concept, and the test on the sample for several months shows that the protection effect on cervical vertebra, vertebra and lumbar vertebra is far beyond expectations. It is also important that the human body can adjust different body positions in the sitting posture, and fatigue caused by keeping a sitting posture for a long time can be greatly relieved. The invention was originally designed primarily for students at home, but test results indicate that it can find application in a wider field. For example: office and entertainment applications. Perhaps, the back sitting posture writing and the back sitting posture office concept can lead to a change in the field of learning, desks and chairs.
