Abstract

The utility model discloses a multifunctional chair which comprises a cushion, a chair frame and a chair-back, wherein the bottom of the chair-back is articulated with one end of the cushion so as to enable the cushion and the chair-back to relatively rotate, the approximately middle part of the chair-back is pivotally arranged on the chair frame by a pivot, a blocking plate is arranged at the bottom of the cushion, a plurality of blocking positions are longitudinally arranged on the blocking plate, and blocking pillars which can be inserted into the blocking positions are arranged on the chair frame. When the chair-back is adjusted backwards to change an office chair into a resting chair, the cushion simultaneously moves forwards to cause the gravity center of the office chair to move forwards, and the gravity center of the human body moves forwards correspondingly to keep the resting chair balanced, thereby improving the safety factor of the office chair taken as the resting chair and preventing the accident of tilting backwards with a person and the chair; in addition, the utility model has simple structure, convenient operation, wide application field and low cost.

Description

Multifunctional chair

Technical field

The utility model relates to a kind of multifunctional chair that collects office, perches oneself on one.

Background technology

Along with rhythm of life is accelerated, after work busy in anxiety, people often wish the energy respite for a moment.But owing to be subjected to the restriction of office conditions, people can only lie prone on the desk or lean against on the office chair and have a rest, thereby have a strong impact on people's rest quality.The tradition office is a lot of with the kind and the pattern of chair, multiple functional, but usually just in order in office process, to provide a kind of comfortable sitting posture to people, it can not be adjusted into the instrument that couches for people mostly, though the angle of inclination of the office chair chair back that has can be regulated, so that people can more cosily face upward by having a rest on the office chair, but the chair back of this type of office chair is when regulating backward, the center of gravity of office chair also moves thereupon backward, when people face upward when leaning against on the office chair, the people might take place to connect with the chair incident of overturning backward, thereby reduced the security of office chair as tool for taking rest the time.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, easy to operate, multifunctional chair that safety coefficient is high.

The technical scheme that its technical problem that solves the utility model adopts is:

Multifunctional chair, comprise cushion, chair frame and the chair back, described chair back bottom is hinged with an end of cushion, so that can relatively rotate between the cushion and the chair back, the chair back roughly middle part is hubbed on the chair frame by pivot, the bottom of described cushion is equipped with block board, is vertically arranged with some screens on the block board, and the card post that can insert in the screens is installed on the chair frame.

Described screens is provided with two, and block board is provided with bar hole, and two screens are separately positioned on the two ends of bar hole and are communicated with bar hole;

Card post of the present utility model can adopt screw rod.

As the utility model improvement of the technical scheme, the bottom of chair frame is equipped with lifter, and an end of lifter is connected with a foot rest, and foot rest is equipped with universal wheel.

The beneficial effects of the utility model are: the angle between the cushion of the present utility model and the chair back can be regulated by the card post on screens on the block board and the chair frame, office is become with chair have a rest when using chair when regulating the chair back backward, cushion moves forward simultaneously, the center of gravity of office chair is moved forward, people's center of gravity correspondingly moves forward, make rest keep balance with chair, thereby improved the safety coefficient of office chair when having a rest with chair, people from the company of preventing is with the chair incident of overturning backward; And of the present utility model simple in structure, easy to operate, the field that is suitable for is extensive, and cost is low.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the schematic perspective view of the utility model when using as office chair;

The schematic perspective view of Fig. 2 when to be the utility model as having a rest use with chair;

Fig. 3 is the schematic perspective view of cushion.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, multifunctional chair of the present utility model, comprise cushion 1, chair frame 2 and the chair back 3, the both sides of chair frame 2 are provided with handrail 4, wherein an end of the chair back 3 bottoms and cushion 1 is hinged, the chair back 3 roughly middle part is hubbed on by pivot 5 on the handrail 4 of chair frame 2, can make between the cushion 1 and the chair back 3 and can relatively rotate when pulling cushion 1, and the chair back 3 pivots by the handrail 4 of pivot 5 with respect to chair frame 2 both sides simultaneously.

In the bottom of cushion 1 block board 6 is installed, be vertically arranged with two

screens

61,62 on the block board 6, the card post that can insert in the

screens

61,62 is installed on the chair frame 2, and this card post can adopt screw rod 7 as shown in the figure, adopts screw rod 7 can be convenient to screens and the location that is connected of blocking between the post.

Block board 6 is provided with bar hole 63, two

screens

61,62 are separately positioned on the two ends of bar hole 63 and are communicated with bar hole 63, the card post need not be taken out in screens when regulating the angle of the cushion and the chair back, and it is simple in structure, easy to operate, and production cost is low.

In the bottom of chair frame 2 lifter 8 is installed, an end of lifter 8 is connected with a foot rest 9, and foot rest 9 is equipped with universal wheel 10, can regulate the height of office chair by lifter 8, and adopts universal wheel 10 can be convenient to moving of office chair.

With reference to Fig. 1, when the screens 61 on the cushion 1 bottom block board 6 cooperated with screw rod 7, the angle between the cushion 1 and the chair back 3 was near 90 degree, and this moment, it can be used as the office chair use; With reference to Fig. 2, when regulating the angle of the chair back 3 and cushion 1, spurring cushion 1 forward makes screens 62 cooperate with screw rod 7, the chair back 3 is that the axle center rotates backward with pivot 5, make between the cushion 1 and the chair back 3 formed angle between 120 to 130 degree, office chair can be used as rest and used with chair this moment, and changing between the cushion and the chair back in the angle, because cushion moves forward, the center of gravity of office chair is moved forward simultaneously, and people's center of gravity correspondingly moves forward, and makes rest keep balance with chair, thereby improved the safety coefficient of office chair when having a rest with chair, people from the company of preventing is with the chair incident of overturning backward.
