Abstract
The utility model relates to a handrail structure for the volume-saving folding chair. A chair back is movably connected with the rear of a cushion; two front and two back legs are movably connected with the outer sides of the cushion, and a connector is arranged among the back legs, the cushion and the chair back respectively for connection; a handrail is arranged at the upper end of the front and the back legs, wherein the handrail is made with a single plate, and is movably connected with the upper ends of the front and the back legs through the shaft connecting pieces at the bottom. The utility model is more particularly suitable for process with a single metal plate to replace the frame injection molding handrail of the volume-saving folding chair.
Description
Technical field
The relevant a kind of province of the utility model volume of timber folding chair armrest is meant that especially this folding chair can be under the saving packing volume of timber, with chair pin before and after the handrail connection of single plate-sheet-type mouldingization.
Background technology
Traditional Chinese chair mostly is fixed, all can occupy sizable space under its normality, when transporting based on a large amount of seats, or can save the volume of timber when seat does not use, and the seat that can be folded is to arise at the historic moment.
General seat comprises that mainly seat cushion, the chair back, front and back chair pin and handrail etc. constitute part, when its folded position, seat cushion, front and back chair pin and handrail all rely on the chair back and become a strip, and the volume of whole seat when not using or transporting can significantly be reduced.But under the folded position of this type of folding chair, its lateral width is still quite big, and the side after it is amounted to is wide more to be reduced, and with the further saving volume of timber, is to become the important topic that can save shipment and delivery cost.
At this point, as United States Patent (USP) the 6th, 217,111B1 number and the 6th, 213, promptly all disclose for 545B1 number and can further dwindle the folding chair that it amounts to the trailing flank width.So can make same transporting with the capacity of the counter more folding chair of can packing into, to save its shipment and delivery cost.But this type of can further save the folding chair of amounting to the back volume of timber, its mostly essential shaped as frame handrail that uses with the plastic ejection formation.This kind armrest commonly used must use the large mold moulding on the one hand and make cost higher outside, other its structure of aspect more simultaneously, also is not easy to carry out variation in moulding design with this kind structure handrail of fixed mould moulding.
The utility model content
The purpose of this utility model is to provide a kind of province volume of timber folding chair armrest, it is coupling with single plate-sheet-type handrail bottom on the chair pin of sheet connection folding chair front and back, cooperate the chair back two bottom side connectors, whole seat can be amounted to the little volume of timber, simultaneously, more can increase its intensity, reduce manufacturing cost, and be suitable for carrying out various variation in moulding designs because of its handrail spy is suitable for making with the single metal plate sheet.
For achieving the above object, a kind of province volume of timber folding chair that the utility model provides, it comprises: a seat cushion; One movable axis is connected to the chair back of this seat cushion near the rear end; One is mounted on the front chair leg of seat cushion both sides; One is mounted on the back chair pin of seat cushion both sides; Two side-connectors, for make the one end respectively activity be engaged in an above-mentioned seat cushion and a seat back frame, the then movable back chair pin that engages of end in addition; And two side handrails of being located at chair back upper end, above-mentioned front and back, these handrails are made with single plate, and connect the upper end of above-mentioned front and back chair pin with its lower shaft contact pin movable axis, and make the movable chair back both sides that engage, the nearly rear end of these handrails.

The specific embodiment
Please refer to Fig. 1-Fig. 3, with the folding chair in scheming is example, and it comprises that roughly a seat cushion 10, is engaged in the chair back 20 of these seat cushion 10 rear ends, be combined in the front chair leg 30 and the back chair pin 40 of seat cushion 10 both sides, and the main elements such as two side handrails 50 of being located at chair pin 30,40 upper ends, front and back.
For reaching the function that can amount to, the upper end activity of above-mentioned front and back chair pin 30,40 is engaged in the sheet 60 that is coupling of two side handrails, 50 bottoms, and the lower end of these front and back chair pin 30,40 is landed when opening (as shown in Figure 1 and Figure 2).Two side handrails 50 connect near inboard and 20 liang of outer side frame movable axis of the chair back of rear end.Simultaneously, between back chair pin 40 and the chair back 40 are near the outside of lower end, then be respectively equipped with connector 70.
In this embodiment of diagram, connector 70 1 ends extend the fork-join end that is made of two fork sheets 71,72 (with reference to Fig. 3), and other end then makes up one and connects the U-shaped sheet 73 of the chair back 20 and seat cushion 10 frameworks, and constitutes a turning joint.
Main feature of the present utility model is that promptly according to above-mentioned folding chair structure, its handrail 50 can constitute with single plate, to replace the frame ejection formation handrail of economizing volume of timber folding chair commonly used.Whole handrail 50 spies are suitable for metal material moulding, and impose arc processing as shown, and other color or electroplated coating.
The utility model is according to whole above-mentioned folding chair thereby can be converted into state shown in Figure 4, is possessing under the wide province's volume of timber function of smaller side, and whole folding chair can be folded into the side strip, and can be stacked into state shown in Figure 5 mutually.
In Fig. 6, another embodiment of the utility model shown in Figure 7, it can use another kind of connector 700, and this connector is with flat piecemeal activity always be coupling seat cushion and seat back frame, and engages back chair pin with an arc-like sheet body.
The utility model is wide to save the volume of timber except that amounting to into smaller side according to above-mentioned folding chair, and its handrail can improve the intensity of this type of folding chair handrail with single metal plate sheet formation, and more durable in use.
Simultaneously, because handrail can need not use outside the ejection shaping die with plate or moulding, the shape design of its handrail is more diversified, and make things convenient for folding chair is carried out various lining variety design.
