Description

A kind of Novel backrest chair

Technical field

The present invention relates to field of furniture, particularly relate to a kind of Novel backrest chair.

Background technology

In China, chair is that people live a central part, and chair occupies extremely important position wherein.Unify upright stone tablet chair in chair in the seat system of ancient Chinese, focus on decoration and ceremony, thus have to sacrifice the factor of ergonomics and function aspects in seat design.And the chair of another common traditional pattern is lamp extension chair, its seat is generally square, backrest is established arch take brain, and sitting face divides into step doorjamb.The modeling characteristic of chair be exactly backrest without handrail, two that backrest takes brain extends one section.

Chair more re-injection ergonomics hung by lamp, but its structure still dislikes complicated succinct, causes the workload in manufacturing large and numerous, incompatible with the design style of the main flow in modern times on the other hand on the one hand, is difficult to be popular in domestic consumer.

Summary of the invention

Embodiments provide a kind of Novel backrest chair, comprise sitting face frame, sitting face, foreleg foot, back leg foot, backrest, it is characterized in that, described sitting face is arranged in described sitting face frame; Described chair also has front horizontal doorjamb, under described front horizontal doorjamb is positioned at sitting face frame, is not more than the twice of the width of this front horizontal doorjamb with the distance of sitting face frame; Described chair also has left horizontal doorjamb and right horizontal doorjamb, described left horizontal doorjamb with between right horizontal doorjamb with described sitting face frame with fall the oblique doorjamb of herringbone be connected.

Preferably, described sitting face is made up of frid bar arranged side by side.

Preferably, described sitting face adopts synthesis bamboo wood material.

Preferably, described in the outer cause of the backrest of described chair, two back legs foots upwards extend to form.

Preferably, the top of described backrest has raising-and-depression part.

Preferably, the raising-and-depression partial-length of described backrest be backrest height 20% to 50% between.

Preferably, the central authorities of the raising-and-depression part of described backrest are embedded with a block length square plate.

Preferably, the raising-and-depression part of described backrest is made up of several frid bars.

The chair that the embodiment of the present invention provides, comprise sitting face frame, sitting face, foreleg foot, back leg foot, backrest, it is characterized in that, described sitting face is arranged in described sitting face frame; Described chair also has front horizontal doorjamb, under described front horizontal doorjamb is positioned at sitting face frame, is not more than the twice of the width of this front horizontal doorjamb with the distance of sitting face frame; Described chair also has left horizontal doorjamb and right horizontal doorjamb, described left horizontal doorjamb with between right horizontal doorjamb with described sitting face frame with fall the oblique doorjamb of herringbone be connected.The present invention is improved by the simplicity of conventional lights being hung to chair, is easy to volume production manufacture.On the one hand, introduce and fall the horizontal doorjamb of herringbone between horizontal doorjamb and sitting face frame, with the stability utilizing stable triangular principle to keep its entirety, and create larger permeability, also work convenient for cleaning simultaneously for the lower space of seat; On the other hand, ergonomic designs is introduced to back part, the weight that human body back supports is decomposed.Make the entirety of chair more agile easy-to-use, more meet the principle of Eco-Design.

Accompanying drawing explanation

In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

The structural representation of a kind of Novel backrest chair embodiment in Fig. 1 embodiment of the present invention;

Fig. 2 is the top view of Fig. 1;

Fig. 3 is the side view of Fig. 1;

Fig. 4 is the front view of Fig. 1.

Detailed description of the invention

Refer to Fig. 1 to Fig. 4, embodiments provide a kind of Novel backrest chair, comprise sitting face frame 1, sitting face 2, front foot 3, metapedes 4, backrest 5, sitting face 2 is arranged in sitting face frame 1, under front horizontal doorjamb 6 is positioned at sitting face frame, be not more than the twice of its vertical thickness with the distance of sitting face frame.Below horizontal doorjamb 7 sitting face frame 1 both sides, two sides, be placed between front foot 3 and metapedes 4, with between sitting face frame 1 with fall the oblique doorjamb of herringbone be connected.

Before the present embodiment adopts, horizontal doorjamb is near sitting face frame, and less distance is that legs and feet resident space in bottom reserves maximum leeway.The horizontal frame in side and the sitting face frame in two lavatories, left and right pull open a segment distance, and the oblique doorjamb of herringbone 8 is therebetween connected and reaches superpower stable structure intensity with triangle stability principle.

Illustrate the schematic diagram of a kind of embodiment of sitting face 2 in Fig. 1 and Fig. 2 simultaneously.Sitting face 2 sitting face is made up of channel-shaped lath arranged side by side, leaves gap as air-vent between these channel-shaped laths, make user be sitting in above can not feel sultry.Form the channel-shaped lath of sitting face and can adopt the layered bamboo plate that some pieces of yardsticks are identical, layered bamboo plate itself have stability by force, succinct attractive in appearance, on-deformable feature, as sitting face 2, user is used more comfortable.

The backrest of the chair in the present embodiment, upwards extends to form its outer rim by described two back legs foot, can guarantee that backrest has enough structural strengths and security thus.In the present embodiment, the top of backrest has raising-and-depression part, is gone by human body back the weight supportted to decompose.Raising-and-depression partial-length be backrest height 20% to 50% between.This length ratio is applicable to user's common sitting posture in a relaxed state, brings the experience that user is light, comfortable.

In the present embodiment, the central authorities of raising-and-depression part are embedded with a block length square plate, according to the principle of the centralised functions formula decoration in Chinese Ancient Furniture Design, plaque and sitting face frame, horizontal doorjamb are formed the tight support structure with sufficient intensity, adopt small pieces of material as far as possible again simultaneously, the deformation factor effect of material is minimized.

As another embodiment, the raising-and-depression part of backrest can be made up of several channel-shaped laths.Leave gap as air-vent between these channel-shaped laths, make user rest on above can not feel sultry.Form the channel-shaped lath of sitting face and can adopt the layered bamboo plate that some pieces of yardsticks are identical, layered bamboo plate itself have stability by force, succinct attractive in appearance, on-deformable feature, as backrest raising-and-depression part, user is used more comfortable.

The above, above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
