Description

Novel seat

Technical field

The utility model belongs to technical field of furniture, is related to a kind of novel seat.

Background technique

Currently, with healthy living and getting close to natural theory and gradually being received by modern people, wood furniture is increasingly Favor by consumer.Compared with the materials such as plastics, metal, the processing of timber still has its limitation.Therefore to wooden family For tool, meet its characteristic engineering structure play the role of to the quality of product it is very important.Currently on the market pure wooden The couch of frame structure usually allows backrest to be connected with outer yoke, handrail, shape from the stability of processing technology and product At three contact points on mechanics.

Utility model content

The purpose of the utility model is to provide a kind of novel seats, to increase wooden while not damaging its stability The tilt angle of sofa chair back itself.

The utility model is the technical scheme adopted is that novel seat, the outer yoke including frame structure, the outer yoke It is internally provided with inner frame, the inner frame tilts extension upwards and is connected with backrest, is all provided at four endpoints of the outer yoke It is equipped with back leg, two back legs of the two of them far from the backrest are extended with handrail towards the bending of the direction of backrest.

Further, the end of handrail is fixedly connected with the backrest.

Further, two two back legs close to the backrest extend and intersect to the arm rest.

Further, the angle of backrest and the inner frame is 115 degree.

Further, the angle of back leg and the inner frame is 65 degree.

The utility model has the beneficial effects that the link position of backrest and main body frame is moved forward, outside common Yoke is connected with backrest, is changed to inner frame and is connected with backrest.Increase back leg height and tilt angle is allowed to connect with handrail, back leg In addition to having the supporting point also increased outside tie point with handrail with outer skeleton.In this way, leaning in this chair structure There are two tie points for back and handrail, outer yoke, and also there are two tie points for back leg and handrail, outer yoke, with the friendship of backrest and back leg Point is line of demarcation, stable bracket triangle is formed up and down, to reach the stability requirement on mechanics.For man-machine go up, The hypsokinesis angle that wooden sofa chair backrest can be increased guarantees to promote comfort while its stability.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

In figure, 1. backrests, 2. handrails, 3. inner frames, 4. outer yokes, 5. back legs.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and detailed description.

The utility model provides a kind of novel seat, the outer yoke 4 including frame structure, sets inside the outer yoke 4 It is equipped with inner frame 3, inclination extension is connected with backrest 1 to the inner frame 3 upwards, is respectively provided at four endpoints of the outer yoke 4 There is back leg 5, two back legs 5 of the two of them far from the backrest 1 are extended with handrail 2 towards the bending of the direction of backrest 1.

Wherein, the end of handrail 2 is fixedly connected with the backrest 1.Two two back legs 5 close to the backrest 1 extend And intersect to the handrail 2.The angle of backrest 1 and the inner frame 3 is 115 degree.The angle of back leg 5 and the inner frame 3 It is 65 degree.

Wooden sofa backrest tilt angle on open market is mostly 90 degree or is slightly larger than this numerical value, if inclination angle is spent Greatly, it is not good enough to may cause product stability.But Research of Ergonomics shows that the angle of human body the most comfortable is 115 degree or so, is Take into account the comfort level of user as far as possible, current wood sofa chair can arrange in pairs or groups more thick and solid back cushion, pass through back cushion The contact angle of user and wood sofa chair are adjusted with cushion.

It is used the disadvantage is that wooden sofa chair generally has to mating back cushion, seasonal adaptation is poor, and timber structure itself, body It is also poor to feel comfort level.So researching and developing a kind of structure of back gradient that can effectively increase wooden sofa chair with important Meaning.

The link position of backrest and main body frame is moved forward, is connected by common outer yoke with backrest, is changed to in-seam Frame is connected with backrest.Increase back leg height and tilt angle is allowed to connect with handrail, back leg has outside tie point in addition to outer skeleton Also increase a supporting point with handrail.In this way, which there are two connect for backrest and handrail, outer yoke in this chair structure Also there are two tie points for contact, back leg and handrail, outer yoke, using the intersection point of backrest and back leg as line of demarcation, are formed stablize up and down Bracket triangle, to reach the stability requirement on mechanics.For man-machine go up, wooden sofa chair backrest can be increased Hypsokinesis angle guarantees to promote comfort while its stability.

The structure design of the utility model increases the backrest inclination angle range of similar couch, solves man-machine requirement The problem of with the harmony of mechanical structure, structure is simple, is readily produced.

The advantages of the utility model, is as follows:

1, the link position of backrest 1 and main body frame is moved forward, is connected, is changed to by common outer yoke 4 and backrest 1 Inner frame 3 and backrest 1 connect.

2, backrest 1 and the tie point of couch other parts include: backrest 1 and handrail 2, backrest 1 and inner frame 3.

3, the tilt angle for increasing by 5 height of back leg, is only connect with outer yoke 4 by common back leg 5 and is changed to by outer yoke 4 It is connected with handrail 2.

4, back leg 5 and the tie point of couch other structures include: back leg 5 and outer yoke 4, back leg 5 and handrail 2.

5, the tie point in four structures that the utility model design scheme proposes enables backrest 1, handrail 2, outer yoke 4, interior Skeleton 3, back leg 5 form stable bracket triangle, to reach mechanics using the intersection point of backrest 1 and back leg 5 as line of demarcation up and down On stability requirement.

6, the tilt angle of backrest 1 can reach 115 degree or so of ergonomic demands via such structure.

7, the tilt angle of backrest 1 and the tilt angle of back leg 5 are reversely equal.
