Abstract

The utility model provides a working chair on which a person can lie. A supporting telescopic stick which can be extended, shrunk and folded is additionally arranged behind the backrest of the existing working chair, wherein, the joining position of a chair seat board and a chair backrest of the working chair is provided with a movable connector. When the person is in a lying state on the working chair, namely, when the joining included angle of the face of the chair seat board and the face of the chair backrest is adjusted to any angle of 130 DEG to 180 DEG from 90 DEG, the gravity generated by the weight of the body of the person on the chair backrest of the working chair is supported by the supporting telescopic stick of the chair backrest to keep the stabilization of the working chair. The increase of the lying function of the working chair is realized under the precondition that the weight of supporting feet on the lower part of a chair seat board of a common working chair is not increased.

Description

Can horizontal work chair

The utility model relates to a kind of work chair, especially can increase the work chair chair back supporting extension stem of the horizontal function of work chair.

At present, known chair plate and chair back joint are equipped with the work chair of flexible jumper, when the engage angle of chair plate face with the chair back face, transfer to 130-180 when spending by 90 degree, the people sits and crouches on work chair, the gravity that person weight produces on the chair plate, add the gravity of chair plate lower support pin can not the balance chair backrest on the gravity that produces of person weight, and chair back does not have support to support, and chair will fall down by loss of equilibrium backward.Make work chair obtain balance and do not fall down backward, the work chair that has just strengthens the weight of chair plate lower support pin to 60kg, so just can reach the people under horizontal state on the work chair, the purpose that keeps the work chair balance not fall down backward.This work chair weight is big, and manufacturing expenses increase, carrying and use inconvenience, and the work chair of other kind does not have horizontal function.

The purpose of this utility model provide a kind of can horizontal work chair, under the prerequisite that does not increase existing common work chair chair plate lower support pin weight, adopt the gravity that person weight produces on the chair back supporting extension stem supporting chair back, making work chair is the work chair, but is again the multifunctional chair of bed rest.

The purpose of this utility model is achieved in that the flexible jumper by chair plate and chair back junction, make work chair chair plate facial with the chair back face engage angle by 90 degree transfer to 180 spend adjustable, the people is horizontal state on work chair, being that the chair plate is facial spends when transferring to any one angle of 130-180 degree by 90 with the angle that engages of chair back face, the gravity that person weight produces on the work chair chair back is by the supporting of chair back supporting extension stem, the gravity that human body weight produces on the work chair chair plate keeps work chair steady by the supporting of chair plate support foot.Owing to adopt such scheme, can be under the prerequisite that does not increase chair plate lower support pin weight, the crouched function of setting up work chair, chair back only adopts the chair back supporting gentry rod that contracts to do support, and is simple in structure.

Further specify this use is novel with enforcement is following below in conjunction with accompanying drawing:

Fig. 1 is can the following side sectional structural map of first enforcement of horizontal work chair.

Fig. 2 can implement following side sectional structural map by second of horizontal work chair.

1. chair plates, 2. chair backs, 3. chair backs supporting extension stem, 4. flexible jumpers, 5. movable hinges, 6. chair plate support foots, 7. adjusting gong posts, 8. interior telescopic mast 9. rods overlap 10. grooves among the figure

In Fig. 1, the flexible jumper (4) that chair plate (1) engages with chair back (2) can make easily chair plate (1) facial with chair back (2) facial engage angle by 90 degree transfer to 180 spend adjustable.When the angle that engages that chair plate (1) is facial and chair back (2) is facial is spent when transferring to any one angle of 130-180 degree by 90, the gravity that chair back (2) is gone up the generation of person weight supports extension stem (3) supporting by chair back, and chair back supporting extension stem (3) is regulated gong post (7) by the interior telescopic mast of rod cover (9) (8) and constituted.Telescopic mast (8) all retraction rod overlaps in (9) or stretches out rod cover (9) 31cm in addition, and it is 38cm that rod overlaps (9) length, and rod cover (9) and interior telescopic mast (8) tighten up by regulating gong post (7).When the people need be on work chair during rest, opening movable hinge (5) draws back chair back supporting extension stem (3) and opens flexible jumper (4) again, adjust the facial angle that engages with chair back (2) face of chair plate (1) as required, pulling out the interior telescopic mast (8) of chair back supporting extension stem (3) then locates to ground, tighten up and regulate gong post (7), work chair enters horizontal state.

In embodiment illustrated in fig. 2, when the people need work on work chair, turn on and regulate gong post (7) in interior telescopic mast (8) the retraction rod cover (9), tighten up and regulate gong post (7) and chair back is supported the superimposed groove (10) in chair back (2) back of extension stem (9) locate, open flexible jumper (4) then, adjustment work chair seat (1) face engages angle to the 90-100 degree with chair back (2) face, and work chair is the work of returning to chair state just.

Claims

1. what a chair plate (1) and chair back (2) joint were provided with flexible jumper (4) can horizontal work chair, it is characterized in that: centre position, upper end, chair back (2) back is provided with movable hinge (5) and chair back supporting extension stem (3), the movable hinge (5) of chair back (2) back is connected with chair back supporting extension stem (3), and chair back supporting extension stem (3) is regulated gong post (7) by the interior telescopic mast of rod cover (9) (8) and constituted.
