Background

There are a wide variety of chairs, with or without a backrest, with plastic or iron or wood chairs, with foldable chairs and with non-foldable chairs, etc.

The chair functions as a seat for a person to sit on, and therefore, the chair must have a seat plate. The common materials of the seat plate of the existing chair are wood plate, iron plate and plastic plate. The cost of both the wood plate and the iron plate is high, and the iron plate has good strength, but is heavy and has poor comfort (a soft cladding is often arranged on the surface). Although the plastic plate is lighter than the iron plate, the thickness is large (the thickness is at least two millimeters) in order to meet the strength requirement, the thickness is larger in general injection molding, and if the thickness is larger in rotational molding, and the manufacturing cost is not low because the bottom is provided with the reinforcing ribs with different transverse and vertical intersections. Therefore, it is necessary to inventively improve the seat plate structure of the chair in order to reduce the weight and cost of the seat plate of the chair.

Detailed Description

Referring to fig. 1, the chair is a foldable chair, which includes a backrest structure 10, a seat structure 20 and supporting leg structures 30, wherein the supporting leg structures 30 support the backrest structure 10 and the seat structure 20, and the seat structure 20 can be folded along with the supporting leg structures 30, and in fact, the connection mode between the three structures is the existing structure, so the folding principle of the foldable chair is not explained.

Referring to fig. 2 to 4, the seat plate structure 20 includes a seat plate 22 and a metal frame 24. The seat plate 22 is a plastic-suction molded plastic suction plate with a thickness of about 1mm, even 0.5mm, is flexible and bendable, and the seat plate 22 comprises a panel 221 and a surrounding edge 222 which is connected with the peripheral edge of the panel and is arranged downwards. The metal frame 24 is a ring and is disposed around the seat plate 22, and the bottom end of the metal frame 24 is bent outward to form a hook 241. The lower end of the surrounding edge 222 of the seat plate is inserted into the hook 241 from the top down, and the metal frame 24 is leaned against the inner side of the surrounding edge 222, and the hook 241 is fixed to the lower edge of the surrounding edge 222 by riveting and clamping. That is, during assembling, the surrounding edge 222 may be inserted into the hook 241, and then riveted, so that the hook 241 is deformed and pressed to fix the surrounding edge 222, and the seat plate and the metal frame are integrated.

Preferably, the middle of the panel 221 is in a concave arc shape, or the panel 221 is in a concave arc shape. Thus, the panel 221 is not a flat surface, and has a curvature, so that the stability is better, the panel is not easy to deform, and the tensile strength is better. The shape of the concave arc surface is not necessarily symmetrical in front and back and left and right, and the concave arc surface can be concave at the part which is attached to the human body.

Preferably, the connecting portion of the panel 221 and the surrounding edge 222 is concave inwards to form an arc transition shoulder 223, so that an upper step and a lower step, an upper step 224 and a lower step 225, are formed between the surrounding edge and the panel, and therefore, the three-dimensional shape is more prominent, and the visual feeling of firmness and thickness is obtained. It is further preferred that the metal frame 24 provides a supporting force to the lower step 225, which inevitably increases the load-bearing capacity of the seat plate 22, but also provides a supporting force to the upper step 224.

Preferably, the cross-section of the metal frame 24 has a closed cavity 242, which in this embodiment is rectangular in shape. Thus, the metal frame 24 is actually understood as a support tube, and is better in rigidity and strength.

Referring to fig. 5 and 6, in a first modification of the seat plate structure, one or more reinforcing rods 243 are additionally disposed in the metal frame 24, and the reinforcing rods 243 are supported on the lower surface of the panel 221. It will be appreciated that such reinforcement bars 243 support the panels 221, and the limits of the overall seat pan structure to withstand the force of gravity are of course higher. Preferably, the end of the reinforcing bar 243 is bent outward and obliquely downward to form a connecting angle 244 (the connecting angle at both ends is in a shape of a figure of eight), and the connecting angle 244 is connected to the inner side surface of the metal frame 24. This connecting angle 244 is formed at the end of the reinforcing bar 243, and has a small length, so that it is very resistant to bending, and thus the reinforcing bar 243 is not easily deformed when supported.

Referring to fig. 7 and 8, in a second variant of the seat plate structure, the metal frame is not a tube structure, i.e. has no internal cavity, but a sheet structure, i.e. the cross section of the metal frame 24 is a sheet. Further preferably, the upper end of the metal frame 24 is shaped to correspond to the arcuate transition shoulder 223 so as to abut against the lower surface of the arcuate transition shoulder. Obviously, this may provide more support to the arcuate transition shoulder 223 or the metal frame may provide more support area to the seat plate.

Referring to fig. 9, a third modification of the seat plate structure is made based on the second modification, and the principle is the same as the first modification, specifically: a strip-shaped reinforcing sheet 245 is arranged in the metal frame 24, and the strip-shaped reinforcing sheet 245 is supported on the lower surface of the panel 221. Preferably, the ends of the elongated reinforcing pieces 245 are bent downward and obliquely outward to form connecting corners 246, and the connecting corners 246 are connected to the top ends of the metal frames 24. The action of the elongated reinforcing sheet is referred to the reinforcing bar of the first modification.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
