Description

Folding bed computer tables and chairs

Technical field

The present invention relates to the injury bringing to human body when human factor engineering is used computer work, leisure, amusement to solve on shelf bed.

 

Technical background

When consumer uses computer in bed, a bed computer desk in the market of using does not have chair supporting with it, and long-time sitting behind can allow people feel without any support to have a pain in the back, serious harm user's lumbar vertebrae.With self experience and observation, draw, user's generation backrest that can gather into folds rearward with the article of the quilt on bed or pillow and so under rascal, but the product of the formation under these rascals does not meet ergonomics, although can alleviate a little user's discomfort on definite meaning, but not the way of dealing with problems eventually, still human body is caused to certain injury.

What in this, be seriously injured is to take university student as main crowd.What the older generation's dormitory in current university was still used is the shelf bed of upper and lower general layout, and tables and chairs arrange in addition; The equipment before 10 years is still continued to use in dormitory space, does not set the position of placing computer, does not meet the fact that current student enrollment 80 percent has computer.Space is too narrow and small causes wherein Most students to have to use in bed computer and do the homework with spreading unchecked of notebook computer, especially schoolgirl because of these reasons with to the attachment of bed, cause them to stay in the bed by most of time, due to the physical trait of women at girlhood, these harm of health to them are heavier.

For current undergraduate feature, the colony that the university student of take is at present main body, is badly in need of producing a kind of cheapness, easy to use, meets ergonomics and does not use time space-efficient Computer table and chair.

 

Summary of the invention

For solving undergraduate health problem, guarantee that following foundation grow up healthy and sound, be badly in need of producing a kind of easy to use, meet ergonomics and joint space-efficient bed computer tables and chairs.

The technical solution adopted for the present invention to solve the technical problems is; by human factor engineering, protecting as much as possible human body is principle; the foldable bed computer tables and chairs of design; within the scope of ergonomics, adjustability meets crowd's use of various builds; fold up the thickness that only has 3-5cm, reduce as far as possible shared space.

The invention has the beneficial effects as follows, when offering the bed desk of student enrollment's work, study, amusement, set up backrest student enrollment learns in bed to solve, work, amusement and the health problem that do not have backrest to bring.

 

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is further described.

Fig. 1 is for launching to use stereogram

Fig. 2 is folding storage stereogram

Fig. 3 is left view

Fig. 4 is that A point amplifies machine drawing

Fig. 5 is that BCD point amplifies machine drawing

The specific embodiment

Fig. 1 expansion time-distance has certain space from wall, and can only be installed on left side use, to the right hand, stops enough activity spaces.

During Fig. 2 folding storage, backrest is in inner side, and desktop is in outside, and handware, in centre, is avoided the threat of handware.

Fig. 4 has a plurality of jacks, and latch can be changed jack, and in order to regulate the height of desktop and backrest, the axle of desktop and backrest is all cross bayonet socket, can only 90 ° of rotations, and limits product can only present to be launched to use and two kinds of forms of folding storage, simple, facilitate; Latch middle part is added with screw thread, reduces the probability that latch comes off and loses, and Fixed latches in the jack of suitable oneself height only needs upper end support upwards to lift later while using, and holds expansion that rotation after cross end can reach desktop and backrest high and folds.

In Fig. 5, B point is C shape draw-in groove, can firmly be fixed on square column type support; If support be cylinder or angle bar also can, the prolongation of C shape draw-in groove upper end can prop up the upside of bed board, fixes below with D point screw; C point is sliding tray, in order to regulate the horizontal range between desktop and backrest.

When this product is used first, B point C shape draw-in groove is stuck in the inner frame of bilevel shelf bed, tightens D point bolt, first fixing just needn't movement more later; Regulate the jack of A point latch, selection is applicable to the fixing upper bolt of height use next time of self and also needn't moves again; When each use or folding storage, only the upper end of vertical support frame need be pulled up, hold the rotation of cross end high and can realize; Direct pull desktop, is used the chute that C is ordered to regulate the horizontal range between desktop and backrest.Desktop and backrest can arrive suitable angle around the pillar rotation of E, F.

Claims (3)

1. folding bed computer tables and chairs, the bed computer desk on market does not have backrest; It is characterized in that: the accessory products as shelf bed exists, and is fixed on the Computer table and chair on upper and lower two-layer shelf bed, has desktop and the chair back.
