Abstract

The utility model relates to a posture correcting armchair for students' study, which is composed of an armchair, a protective frame and a supporting column, wherein, the protective frame is composed of fixing brackets, wooden boards which are provided with chutes, position limiting brackets and crank branch pipes; the wooden boards are connected with the fixing brackets; the position limiting brackets are inserted into the crank branch pipes, and the position limiting brackets can be adjusted up and down; the crank branch pipes are arranged in the chutes of the wooden boards; the joints of the crank branch pipes are provided with axle holes which have keyways, and the keyways and the axle holes are connected by axles; the upper parts of the crank branch pipes which can be opened inward and outward are fixed to the armchair by fixing bolts; the outer end of the supporting column is arranged in the two chutes of the wooden boards. The utility model has the advantages that the additional parts can be disassembled from the armchair without destroying the original structure of the armchair and affecting use afterwards; the length of the supporting column can be adjusted free from limitation of the armchair, and thus the scope for use is enlarged; the influence of the supporting column on curved vertebral columns enables students to correct sitting postures so as to achieve the effect of curved vertebral column prevention.

Description

The student learns posture correcting chair

The utility model relates to a kind of student and learns posture correcting chair, belongs to a kind of in the culture and education apparatus, especially belongs to a kind of in student's seat.

The student often can occur crooked back, rickets unconsciously and chest or forward lean from some bad habits such as books are very near in study, reading, these bad habits all will influence the healthy of student.And at present the rectification of this bad habit is had only attention by student self, help equipment without any the outside and remind, help the student and correct faulty posture, for this reason, I design a kind of posture correcting chair, give the student with the helping of outside, help the student to keep the good appearance of doing.

The purpose of this utility model is that the protector that is easy to mount and dismount is installed on conventional armchair, gives the student auxiliary, prompting with the outside, helps the student to correct bad learning posture, prevents spinal curvature and the myopia that too closely causes from books.

Structure of the present utility model is: by armchair, protective frame is formed with the fore-set that prevents spinal curvature, wherein, protective frame is identical by structure, two parts of symmetrical configuration are formed, comprise fixed mount, one-sided or both sides have the plank of chute, spacing holder and crank arm, plank links to each other with fixed mount, spacing holder is inserted in the crank arm top and can be stretched according to different height requirement, regulate, the crank arm is installed in the interior or external chute of plate and can moves forward and backward in chute, caging bolt can be located the crank arm in interior or external chute, set bolt on the fixed mount is fixed on protective frame on the handrail of armchair, the crank arm is divided into, following two sections, connect with axle each other, the identical another part of the structure of protective frame is fixed on the opposite side handrail, fore-set is connect by three different pipe boxes of external diameter to be formed, pipe can be in the outer tube at place, centre inwardly in two sections, outer indentation or pull out, adapting to the seat of different in width, the two ends of pipes are installed in the inboard chute of two planks in two.

The utility model has the advantages that 1. simple in structure, easy for installation, can be at any time from the armchair dismounting or install, do not destroy the original structure of chair, do not influence the later use of chair, and change the limitation of existing armchair special purpose; 2. the length of fore-set is scalable, makes the utility model use the size restrictions that is not subjected to armchair, enlarges range of application of the present utility model; 3. the utility model can make the student correct sitting posture by the effect of fore-set to curved spine, thereby reaches the song back of the body that prevents that writing posture is incorrect and produce; 4. utilize the restriction of spacing holder, can prevent that the student from reading, writing and cross near and asthenopia and myopia that cause from books.

Fig. 2 is the front view of protective frame

Below in conjunction with accompanying drawing the utility model is described specifically:

Referring to Fig. 1, Fig. 2, the student learns posture correcting chair, by armchair, protective frame is formed with the fore-set 5 that prevents spinal curvature, wherein, protective frame is identical by structure, two parts of symmetrical configuration are formed, comprise fixed mount 6, one-sided or both sides have the plank 4 of chute, spacing holder 7 and crank arm 1 are formed, plank 4 is connected and fixed with fixed mount 6, spacing holder 7 is inserted in the crank arm 1 and can be stretched according to different height requirement, regulate, crank arm 1 is installed in the interior or external chute of plate 4 and can moves forward and backward in chute, caging bolt 3 can be located crank arm 1 in external chute, crank arm 1 is divided into two sections, the junction of two sections has the axis hole of band keyway and connects with axle 2, like this, the top of crank arm 1 can inwardly be closed or outwards open, connecting by key also can be with the location, top of crank arm 1, set bolt on the fixed mount 6 is fixed on protective frame on the handrail of armchair, the identical another part of protective frame structure is fixed on the opposite side handrail, fore-set 5 is connect by three different pipe boxes of external diameter to be formed, pipe 8 can be in middle outer tube inwardly in two sections, outer indentation or pull out, to adapt to the seat of different in width, the outer end of two interior pipes is installed in the inboard chute of two planks 4.

The armchair of installing protective frame has just constituted that the utility model---the student learns posture correcting chair, when the student will sit in chair, earlier the top of crank arm 1 is outwards opened, the inboard chute of fore-set 5 along plank 4 advanced, near the chair back, after seated, according to writing, the required distance of reading moves forward and backward crank arm 1 in the interior or external chute of plank 4, choose the seat, with bolt 3 with crank arm 1 fixed position, simultaneously, according to the top angle of selected good crank arm 1, the top of crank arm 1 is fixed with key, writing this moment, during reading, the student learns posture correcting chair and just can have an effect.
