Description

Adjustable, detachable chair

But the movable joint chair of complying with one's wishes is the utility model invention of the novel daily furniture of a kind ofly sitting, can lie, can sleep Winter-summer dual purpose, can regulate just in accordance with the wishly.

Furniture in the market to multi-functional, removable repeatedly, the direction of light province material develops, folding chair, folding bed and so on are popularized, but because they all adopt " the post shelves are along colluding--straight support " structure, limited the mobility scale of angle, therefore can only be shunk folding in time spent not, the elevation angle of backrest then can not be regulated in use on demand, can only fix an angle, more can not realize chair--the conversion between the bed, this has just limited folding chair, the scope of application of the bed that changes.Want to lie on the back as after old man's sitting, conventional chair have to be changed chaise longue and so in addition because angle can not be adjusted and can't realize, quite needs or exert great effort.Laid-up people wants to sit up by once, and common bed also is difficult to reach requirement, have to cotton-wadded quilt and so on pad rearward against, very inconvenient.The needs of real life require the restriction of the current global angle of the angle excursion Gonna breakthrough of folding chair, bending machine and so on, make excursion bigger, and can regulate just in accordance with the wishly, can not only sit, can lean on, can lie, can sleep, can also realize chair easily--the conversion between the bed, this is the purpose of the present utility model just.

The purpose of the present utility model is achieved in that " the post shelves are along colluding--straight support " structure in the general folding chair is changed into " the post shelves are along colluding--counter collude support " structure.The post shelves all have zigzag hook arrangement along colluding with counter colluding in the support, anti-support leg and the sawtooth that colludes support can be made into one group of mutual interlock along any one sawtooth that colludes with the post shelves, determine an elevation angle of backrest, also can with the post shelves along another sawtooth combo interlock of colluding, determine another elevation angle of backrest, the multi-angle adjusting that has realized movable joint chair as one wishes therefrom is until chair--and the mutual conversion between the bed has reached the purpose of the present utility model.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 has anti-support ［ 1 ］ and the post shelves of colluding along colluding the movable joint chair as one wishes of ［ 2 ］, and counter support ［ 1 ］ and the post shelves of colluding are located at the rear portion of movable joint chair as one wishes along colluding ［ 2 ］.Counter colluding has zigzag hook arrangement ［ 3 ］, ［ 4 ］, ［ 5 ］ in the support ［ 1 ］, support leg ［ 6 ］, the post shelves then have zigzag hook arrangement ［ 7 ］, ［ 8 ］, ［ 9 ］ along colluding on ［ 2 ］, instead collude support leg ［ 6 ］ in the support ［ 1 ］ and zigzag hook arrangement ［ 3 ］, ［ 4 ］, ［ 5 ］ can be selected arbitrarily to cooperate along zigzag hook arrangement ［ 7 ］, ［ 8 ］, ［ 9 ］ of colluding on ［ 2 ］ with the post shelves, an elevation angle of backrest has all been determined in each assembly to interlock.As the anti-sawtooth ［ 3 ］ and suitable sawtooth ［ 7 ］ the pairing interlock of colluding of post shelves that colludes in the support ［ 1 ］, then make the movable joint chair of complying with one's wishes become shape shown in Figure 2, can sleep this moment as single bed.As the anti-support leg ［ 6 ］ and suitable sawtooth ［ 7 ］ the pairing interlock of colluding on ［ 2 ］ of post shelves that colludes in the support ［ 1 ］, then become shape shown in Figure 1, can make seat this moment and use.The mode of carrying out combinations of pairs according to this method has six kinds, and each has determined that one of backrest is opened elevation angle degree, regulates thereby make the movable joint chair of complying with one's wishes can carry out the convenient of six kinds of angles, realizes its " seat ", " leaning on ", " sleeping " multiple function.

The key of movable joint chair of complying with one's wishes is " the post shelves are along colluding--counter collude support " structure, interlock is firm, easy to adjust, the needs that adapt to very much daily life, can make wooden bamboo structure, also can make wooden rattan structure or steel-wood structure, on posture change total " seat ", " lean on ", " lie ", " partly lie ", " just sit ", six angles of " sleeping ", do not account for volume at ordinary times, time spent converts easily, but all relaxation and happiness ground operations of child old man are suitable for old person especially and use, mix wheel, just become wheelchair as one wishes, as shown in Figure 3, can use for the patient, can convert in case of necessity becomes to make things convenient for sick bed, to adapt to the needs of current middle and small hospital.
