Description

Inside bearing structure of seat support

Technical Field

The application belongs to the field of seating furniture, and particularly relates to an internal supporting structure of a seat and the seat with the supporting structure.

Background

The internal framework of the existing soft-package seat can be divided into the following three types: the three structural modes respectively have the advantages and the disadvantages of plastic forming, curved wood plate die pressing forming and iron frame matching with the flat seat plate, and the plastic forming and the curved wood plate die pressing forming have the advantages of deep radian of the framework, large body quantity, high die cost, low production efficiency because only one die can be manufactured at a time, and can be used for manufacturing the seat with round and attractive connecting arc between the seat and the back. The technical scheme of the manufacturing method of the multi-layer glued bent wood chair and the bent wood foot blank disclosed in the application publication number CN 102848445A is as follows: the manufacturing method of the multi-layer glued bent wood chair comprises the following steps: 1. manufacturing a foot blank; the first step: manufacturing a veneer; and a second step of: manufacturing a wood chip group; and a third step of: pressing the foot blank; fourth step: preparing a foot blank; fifth step: drilling holes, correcting, sanding and painting the foot blanks; 2. and (5) assembling. The curved wooden chair with smooth lines can be manufactured after the steps are not inferior to those described above, and the finished product is beautiful, but the working procedures are more, the mould is more and the cost is high.

The iron frame is matched with the flat seat plate, the iron frame strip can be changed randomly, the bending pipe die is low in cost and high in efficiency, but the bending pipes are straight strips, the seat after the soft package is harder outside the connection of the seat base and the seat back, forms an acute angle, has weak streamline feeling and poor aesthetic property, if the seat with round and smooth appearance and strong streamline feeling like plastic and bent wood plates is manufactured in the form of the iron frame, each bending pipe at different positions is required to be bent into radians with different requirements, so that more bending pipe dies are caused, the production and the processing are troublesome, and the production cost is greatly improved. Therefore, there are two main types of soft-pack chairs available in the market: 1. the high-cost soft-package seat with strong streamline sense is directly manufactured by plastic and a bent wood plate; 2. a soft package seat with low cost and poor streamline feeling is made by matching an iron frame with a seat plate.

The iron frame is matched with the seat board, the connection position between the seat and the chair backrest is arranged on the bearing seat surface of the chair, the seam is easy to cause uncomfortable sitting feeling of a human body, and the connection position is easy to loosen and disconnect. And when adopting the iron pipe to bend into the excessive structure of round arc promptly (i.e. bottom chamfer), the limitation is great, thereby difficult adjustment or unable adjustment is high to the precision requirement of seat support size after the chamfer shape is fixed, and the commonality of back of the chair is poor, and the return bend stretches to the seat face part and forms the neutral at the bedplate border, has also reduced the travelling comfort of sitting and feel.

Disclosure of Invention

Preferably, the seat support plate is quadrilateral in plan view and three side edge portions thereof have the arc-shaped transition portions.

Preferably, the arc-shaped transition portions of the three side edge portions of the seat surface supporting plate are in smooth transition and have a flush top edge which is abutted against the bottom edge of the leaning frame.

Preferably, the leaning frame is a frame structure and comprises an upper frame forming the shape of the armrest and/or the backrest of the chair, a shaping frame forming the bottom edge and a support connecting rod connected between the upper frame and the shaping frame.

Preferably, at least part of the support links are rectilinear.

Preferably, at least one side edge of the seat support plate is provided with an arc-shaped chair mouth part which extends downwards from the flat middle part and is integrally formed with the middle part, and the arc-shaped chair mouth part and the arc-shaped transition part are in smooth arc transition.

Preferably, the shaping frame is connected with the arc transition part through a connecting piece, the upper part of the connecting piece is fixedly connected with the shaping frame, and the lower part of the connecting piece is provided with a straight hole for penetrating a screw or a bolt.

Preferably, the two ends of the upper frame, which are positioned on the front side of the seat, extend downwards and are fixedly connected to the two ends of the shaped frame, which are positioned on the front side of the seat.

Preferably, the seat support plate is provided with a plurality of mounting holes which penetrate up and down and are used for mounting chair legs.

A seat comprising a seat surface, a backrest and/or armrests covered or filled with a flexible material, characterized by an internal support structure of the seat according to claim 1 or 2 or 3 or 4 or 6 or 7 or 8.

In summary, the application has the following beneficial effects:

1. the application adopts a mode that the edge of the seat support plate is directly provided with the arc transition part (namely, the seat support plate and the arc transition part form the seat), thereby realizing the round arc transition between the seat and the seat of the soft-packed sofa with the iron frame matched seat structure, achieving the forming effect of plastic and curved wood plates, having strong streamline sense and being more beautiful. The arc transition edge and the seat support plate are integrally formed, so that the integrally formed whole seat can be manufactured in a one-time compression molding mode, and the arc degree of the seat is small, the body weight is small, the die is simple, the cost is low, at least 3-4 dies can be manufactured at the same time through one-time compression, and the processing efficiency is high. On the premise of forming a round transition arc, the support connecting rod only needs to adopt a straight rod, and is free of a bent pipe and a bent pipe mold, so that the production efficiency is greatly improved, and the cost is saved. Of course, it is not excluded that the middle part of the support link is curved or bent when the aesthetic and comfort aspects of the chair rest are considered, and the main purpose of the application is to provide a rounded transition of the connection position of the rest frame, i.e. the chair rest, with the seating surface.

2. The whole seat surface of the application is pressed by the plate body without gaps, the sitting feeling is comfortable, the connection position of the chair backrest and the chair seat is not on the seat surface, the connection is convenient, the connection strength is high, and the chair is not easy to damage.

3. The chair seat and the chair backrest have good universality and are convenient to machine and adjust.

4. The framework structure of the application has the advantages of convenient processing, high processing efficiency and low cost. The effect of strong streamline sense of connection between the chair seat and the chair backrest and smooth transition is realized in the lowest cost and the most convenient structural mode.

5. The chair seat formed by pressing is not easy to rebound and deform due to the shallow radian, has good uniformity, is convenient to assemble, is an iron frame structure convenient to adjust even if slightly deformed, and is easy to work during matching.
