Description

Integrated plastic chair

Technical field

The utility model is related to a kind of Plastic chair, more particularly to a kind of integrated plastic chair.

Background technology

Chair is in daily life using extensively, and existing chair has bamboo chair, wooden chair, the wooden mixed chair of steel etc., above-mentioned chair Manufacturing procedure is more, and trouble is installed in manufacture.Existing plastic chair is integrated integral molded plastic shaping, or split type, manufacturing procedure mostly Few, pattern is more, it is attractive in appearance, be easy to safeguard, easy cleaning at the same the features such as not being afraid of rainwater and be widely used.With carrying for living standard The progress of high and technology, processes the demand that simple, cheap, comfortable Plastic chair more caters to people.

As China Patent No. is CN201110387952.X《One piece plastic chair》, wherein, the portions of the chair, lean on The back of the body and leg be integrally formed by injection molding method, while portions present " surrender " or flexibility thus occupant body weight work With lower deformation, make base itself will be shaped as being consistent with the shape of occupant to a certain extent so that chair for More comfortable for occupant, the chair is simple to manufacture, but integral molded plastic is integrally formed, and required material is more, weight big and holds It is yielding, make occupant comfortable reaching, while when keeping chair intensity, required complicated, production difficulty is big.

The content of the invention

Technical problem to be solved in the utility model is that there is provided a kind of simple in construction, province for the above-mentioned state of the art Material is so as to obtain the low integrated plastic chair of lightweight, cost.

The utility model solve the technical scheme that is used of above-mentioned technical problem for：A kind of integrated plastic chair, including Seat support, chair back and chair leg, it is characterised in that：Seat support, chair back are made of injected plastic, and chair leg injection while through be blow molded shape Into hollow structure inside, seat support, chair back and chair leg are combined into one formula Plastic chair using injection and blow molding process.

As an improvement, the bottom of seat support is connected by cross-brace rib with chair leg.

As an improvement, seat support upper surface includes the first surface and the second curved surface close to first surface close to the chair back.

As an improvement, chair back is the curved surface that center section is extended with a lateral projection to occupant direction.

As an improvement, the big thickness, and be designed as uneven thickness to its upper of the bottom thickness of chair back.

As an improvement, at least leader on chair back.

The handle can be hole or be projection or crotch that back stretches out.Hole handle can all penetrate chair and lean on The back of the body, also can only extend into a part for chair back.Simultaneously handle can according to the demand of user, for cost, purposes angle, Preferably one whole penetrates the hole handle of chair back.

Compared with prior art, advantage of the present utility model：Seat support, chair back are made of injected plastic, and chair leg is in the same of injection When form hollow structure inside through blowing, and seat support, chair back and chair leg are combined into one formula using injection and blow molding process Plastic chair, such a construction reduces the weight of chair, while raw material are saved, and it is cost-effective, it is that environmental protection is contributed.

Brief description of the drawings

Fig. 2 is the front view of the present embodiment chair；

Fig. 3 is the left view of the present embodiment chair；

Fig. 4 is the upward view of the present embodiment chair.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing embodiment.

As Figure 1-3, in the present embodiment, integrated plastic chair, including seat support 1, chair back 2 and chair leg 3, seat support 1, Chair back 2 is made up of injected plastics material；Chair leg forms hollow structure inside while injection through blowing；Finally utilize injection blowing Processing step combines to form seat support 1, chair back 2 and chair leg 3 Plastic chair of integral type.The chair leg of inner hollow saves former material Material, reduces the weight of chair, has saved cost, the demand of user is met well.

As shown in figure 4, in the present embodiment, the bottom of seat support is connected by a cross-brace rib 4 with chair leg 3, for increasing Plus support force, so as to increase the intensity and steadiness at seat support position.

As Figure 1-3, chair leg 3 includes longitudinal span of a pair of forelegs 31 and a pair of back legs 32, foreleg 31 and back leg 32 Constantly increase from top to bottom, tilts chair leg for upright chair leg, while the pressure being applied in chair leg is reduced The stability of chair is also add, so as to extend the service life of chair.

The upper surface of seat support 1 includes the first surface 11 and the second curved surface 12 close to first surface 11 close to chair back 2.The One curved surface 11 is recessed curved surface, and the second curved surface 12 is the curved surface tilted down.Such curved design adds user and used The comfort of chair, while bigger pressure can be born, adds the intensity and durability of chair.

Chair back 2 is the curved surface that center section is extended with a lateral projection 5 to occupant direction, and lateral projection 5 is with taking a seat The waist of person offsets there is provided lumbar support, and when pressure backward is applied to chair back 2 by occupant, the pressure is used as application Reaction force in lateral projection 5 allows occupant back to lean on backward, adds the comfort level of chair；Chair back top is with Portion is narrow and curved design that middle part is relatively wide, occupant back is more fitted chair back；Simultaneously by accurate force analysis, By the big thickness to its upper of the bottom thickness of chair back 2, and scientific design is uneven gauge meticulously, so adds chair and leans on The intensity of the back of the body, increases security；The design of such chair back better meets the demand that user pursues comfortable safety.

One hole handle 6 is arranged at the top of chair back 2, and the presence of handle 6 allows user is easily mobile to carry chair To desired position, and using the hole for all penetrating chair back, user can be facilitated to fix or be attached at one by multiple chairs Rise, prevent from losing or being stolen.

Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model technical principle is not departed from, some improvement can be also made, these improvement should also be regarded For protection domain of the present utility model.
