The stress surfaces of the backrest and the seat can be made of flexible cords, rubber cords, long thin bamboo chips, metal sheets, plastic films and other materials; the stress surfaces of the backrest and the seat can have the same structures and also different structures; and under the circumstance that the stress surface of the backrest or the seat is made of the flexible cords or the rubber cords, the stress surfaces adopt a twin-frame form, namely, the flexible cords or the rubber cords are made into the stress surfaces on a small frame whose thickness is thinner than that of the seat frame and the backrest frame, and then the small frame is fixed at the rear middle part and the lower middle part inside the backrest frame and the seat frame.

Description

A kind of solid wood, subsides bamboo, the backrest of bamboo seat and the improvement of seat stress surface

Technical background:

Present known solid wood, paste bamboo, the backrest of bamboo seat and seat stress surface have following several: a kind of is the surface that sponge and cloth is fixed on seat and backrest, the stress surface of holding the sponge cushion is a hardboard, another kind is exactly directly to use fillet, plank, the stress surface at bamboo row culture backrest and seat, these fillets, plank, the bamboo bar always with backrest up and down or left and right sides moulding, the front and back at seat or the moulding tenon fourth of the twelve Earthly Branches, the left and right sides connect, generally, the stress surface of seat and backrest and its periphery next-door neighbour's moulding is in same plane, almost there is not difference of height between it, there is moulding in the top of its backrest of solid wood chair of indivedual moneys a little inappreciable difference of height to be arranged with the stress surface ratio, its backrest stress surface of the bamboo seat that has and seat stress surface also have a little inappreciable difference of height with its periphery next-door neighbour's moulding ratio, for in response to the body mechanics, most solid wood, paste bamboo, the backrest of bamboo seat and seat surface can form bending, and its stress surface also can be in same horizontal plane bending with the moulding of bending; Other has a kind of seat is to put very thick cushion on the surface of seat and backrest, but its cushion back and following stress surface or be a monoblock flat board, or be that bar is all around arranged between the framework, there is not difference of height between the latter's framework and the bar.Also have its backrest of a kind of seat and seat stressed about be no moulding, this seat is not in the narration scope; First kind weak point is backrest and the seat surface that cloth and sponge are fixed on seat, after making dirty and damaging, it is all impossible to unpick and wash and change, and several stress surface in back has two effects, the first is placed on cushion on the stress surface at backrest and seat winter, and stress surface works to hold cushion; It two is conversion in season when not re-using cushion, and stress surface will directly be used and contact with human body, because of its such thinking, so the moulding that stress surface always is made into its periphery next-door neighbour is in same plane as far as possible.So just can when considering firmness, use thin moulding to control cost as far as possible, feel too hard but its maximum weak point is a seat.

Summary of the invention:

In order to overcome existing solid wood and to paste bamboo, the backrest of bamboo seat and the deficiency of seat stress surface, the utility model provide a kind of four seasons all comfortable, the cushion of seat sense change face, unpick and wash, change all the stress surface at backrest and seat very easily.

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

The stress surface at backrest and seat is produced on postmedian in the back frame, middle and lower part or bottom in the seat mount, form darker groove between the moulding that allows backrest and seat stress surface and its periphery be close to and hold cushion, cushion is the Winter-summer dual purpose type, in the use of seat, the backrest of seat will no longer contact with human body with the stress surface at seat, and its unique effect is exactly the cushion that is used for holding the Winter-summer dual purpose type.

The stress surface at backrest of the present utility model and seat can be made by tightrope, glue rope, bamboo chip thin, strip, sheet metal, sheet and other material, the structure of backrest and the stress surface at seat can be identical also can be different, under the situation of the stress surface that uses tightrope or glue rope making backrest or seat, what the utility model adopted is the form of two frames, both with tightrope or glue rope after being made into stress surface on the thickness small frame thinner than seat and back frame, again this small frame is fixed on postmedian and middle and lower part in backrest and the seat mount.

Using thin strip thing to make under the situation of backrest and seat stress surface also is the form of two frames, and structure has two kinds, and a kind of is after stress surface is made, and the strip of forming stress surface can the top to bottom, left and right, front and rear activity.Its concrete structure is: in the front and back of seat mount or the inside bottom of right and left bar mill the openning of inverted L shape, do a small frame that internal diameter is consistent with the seat mount internal diameter again, on two relative square bars of this small frame, punch, the direction in hole is an above-below direction, can run through or the side's of running through bar not, again cylinder is squeezed in the hole, the outside is exposed one section, what approach, through hole is beaten at the two ends of strip thing, the diameter in hole is greater than the diameter of cylinder, with what approach, the through hole at strip thing two ends is aimed at the cylinder on small frame both sides, allow cylinder pass through hole, this one side that cylinder is arranged of this small frame being alignd with the bottom of seat mount firmly is connected behind the internal diameter again, and after finishing, the inverted L shape openning is beneath because of the square bar of small frame has been arranged, just become the Baltimore groove of an accumbency, at this moment, approach, the two ends of strip thing just have been lockable in Baltimore groove, and this structure also is suitable for making the backrest stress surface.

Another kind of structure is exactly after stress surface is made, bar or other material of forming stress surface are not movable, its concrete structure is: this one side that makes progress of the openning of L type being milled this small frame under seat mount, two ends that will approach again, the strip thing are placed in the openning, be connected with the bottom of seat mount again, the two ends of strip thin slice are between two frameworks and are tightly pushed down at this moment, so the strip thin slice is not movable, this structure also is suitable for making the backrest stress surface.

Also having a kind of structure is exactly to strengthen the thickness of seat mount and back frame, directly in the front and back of the seat mount that will be connected with stress surface or the middle and lower part of right and left bar inboard mill out the concave groove of accumbency, mill out the openning of L type at the posterior medial of the back frame that will combine with stress surface, again the two ends of tightrope, glue rope, thin, strip thing or other material are fixed in the L type openning in the Baltimore groove with accumbency, have just become stress surface.

Postmedian in backrest of the present utility model and the seat stress surface always is in it directly combines the back frame, middle and lower part or bottom in the seat mount, therefore, before the backrest stress surface, and between its periphery next-door neighbour's the moulding, will form the darker groove that holds cushion on the seat stress surface and between its periphery next-door neighbour's the moulding, the back frame that has and the moulding of seat mount all are straight, one of groove that form between stress surface in it and the framework etc. are dark, rule, flat cube, backrest moulding that has and seat moulding are in response to the body mechanics, be made into bending, the buckling curve that stress surface in it forms is parallel with the buckling curve that the moulding surface forms, so the groove that forms between it also is etc. dark, the depth of groove at backrest and seat depends on the thickness of the cushion of Winter-summer dual purpose type, the wherein one side of the cushion of Winter-summer dual purpose type is to be made by cooling material, cushion all be stuck in the backrest pan throughout the year and the seat groove in, and the cushion at backrest and seat all need not just can take out from groove with hand at any time by means of any apparatus and put into, and the backrest of seat will no longer directly contact with human body with the interior stress surface of seat groove.Such structure can be changed cushion face very easily, be unpicked and washed and change.
