Detailed description of the invention

In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.

As shown in Figure 1, chair for grandstand of the present utility model includes chair frame 1, is movably arranged on cushion 2 and backrest cloth 3 in chair frame.Cushion 2 can coordinate with chair frame activity with backrest cloth 3 after chair frame is launched, and in the seat portion of chair frame 1, places cushion 2, puts backrest cloth 3 and form backrest in the back support bar of chair frame 1; Also can adopt the structure that cushion 2 is direct with backrest cloth 3 and chair frame 1 links together, in chair frame 1, there is arm-rest frame simultaneously, can directly be placed on the chair for grandstand on grandstand step thereby form one.

As shown in Figure 2, chair frame 1 includes a portion, back-rest and armrest part after launching, and chair frame 1 comprises a bottom bracket 11, two arm-rest frames 12 and two back support bar 13.This bottom bracket 11 comprises two parallel bottom surface cross bars 111, and cushion is connected between two bottom surface cross bars 111.Two arm-rest frames 12 are respectively a downward opening inverted U bar, two arm-rest frame 12 perpendicular pin 121 lower ends are articulated in bottom bracket both sides, be that between bottom surface cross bar 111 difference pivot joint two arm-rest frames 12, two outer ends of bottom surface cross bar 111 are articulated in respectively on U-shaped Shu Jiao121 bottom, arm-rest frame both sides.On wherein one end of the transverse bar 122 of arm-rest frame 12, being connected with one can descend to receive and the back support bar 13 of closing on transverse bar above arm-rest frame 122, and back support bar 13 is connected to adaptor 131 on transverse bar 122 and folding forward by one and is connected on the close end of transverse bar 122.In the time chair frame receipts will being leaned on, back support bar 13 is received to front lower place by transverse bar 122 at adaptor 131, when back support bar 13 is launched to erect, puts a backrest cloth 3 between two back support bar 13, just can form the backrest of seat.

For coordinating the folding of chair frame, make chair frame receive and to lean on to middle part, two bottom surface cross bars 111 of bottom bracket 11 comprise respectively the cross support arm 110 of two pivot joints, between two cross support arms 110 of same bottom surface cross bar 111, connect by pin-jointing piece 112 in junction, middle part, the outside that pin-jointing piece 112 is articulated in respectively two cross support arms 110 connects two cross support arms 110, in the time of chair frame folding, two cross support arms 110 folding downwards under the connection function of pin-jointing piece in bottom surface cross bar 111.

In the present embodiment, as shown in the figure, for make between bottom bracket 11 and arm-rest frame 12, be connected more firm, the chair back of chair frame is more firm, chair frame rear is also provided with an auxiliary cross bar 14 and is articulated in two arm-rest frame 12 rears, auxiliary cross bar 14 is arranged on the top of the bottom surface cross bar 111 that is positioned at rear, auxiliary cross bar 14 is also between pivot joint two arm-rest frames 12, be positioned at bottom surface, rear cross bar 111 above, two outer ends of this auxiliary cross bar 14 are articulated in respectively perpendicular pin 121 belows, arm-rest frame 12 both sides, and the cross support arm 141 that this auxiliary cross bar 14 comprises two pivot joints is equally in middle part pivot joint.With connecting by also pin-jointing piece in junction, middle part between one or two cross support arm 141, because auxiliary cross bar 14 is positioned at bottom surface cross bar 111 tops, its cross support arm 141 is all in middle part pivot joint with cross bar 110, therefore bottom surface cross bar is to be connected by an I-shaped brace 15 with auxiliary cross bar 14 on junction, middle part, auxiliary two cross support arms 141 of cross bar 14 and two cross support arms 110 of bottom surface cross bar 14 are connected on four links 151 of I-shaped brace 15, thereby this auxiliary cross bar 14 is connected to bottom surface cross bar 111 tops, also connect support by I-shaped connector 15.
