Detailed ways

In order to further explain the technical solution of the utility model, the utility model is described in detail through specific examples below.

As shown in Figure 1, the grandstand chair of the present invention includes a chair frame 1, a seat cushion 2 and a backrest cloth 3 which are movably arranged on the chair frame. The seat cushion 2 and the backrest cloth 3 can cooperate with the chair frame after the chair frame is unfolded, that is, the seat cushion 2 is placed on the seat of the chair frame 1, and the backrest cloth 3 is put on the backrest bar of the chair frame 1 to form a backrest; The seat cushion 2 and the backrest cloth 3 are directly connected to the chair frame 1. At the same time, the chair frame 1 has an armrest frame, thereby forming a grandstand chair that can be directly placed on the steps of the grandstand.

As shown in FIG. 2 , the chair frame 1 includes a seat portion, a backrest portion and an armrest portion after being unfolded. The chair frame 1 includes a bottom bracket 11 , two armrest frames 12 and two backrest bars 13 . The bottom bracket 11 includes two parallel bottom cross bars 111 , and the seat cushion is connected between the two bottom cross bars 111 . The two armrest frames 12 are respectively an inverted U-shaped bar with the opening facing downwards. The lower ends of the vertical feet 121 of the two armrest frames 12 are pivotally connected to both sides of the bottom frame, that is, the bottom crossbars 111 are respectively pivotally connected between the two armrest frames 12, and the bottom crossbars The two outer ends of 111 are respectively pivotally connected to the bottom ends of vertical feet 121 on both sides of the U-shaped armrest frame. One end of the transverse bar 122 of the armrest frame 12 is movably connected with a backrest bar 13 that can be retracted and leans against the transverse bar 122 above the armrest frame. The backrest bar 13 is connected to the transverse bar 122 and folded forward. The adapter piece 131 is connected to the proximal end of the transverse rod 122 . When the chair frame is to be retracted, the backrest rod 13 is retracted forward and downward on the transverse rod 122 at the adapter 131, and when the backrest rod 13 is unfolded and erected, a backrest cloth 3 is placed between the two backrest rods 13, Just can form the backrest of seat.

In order to cooperate with the folding of the chair frame, so that the chair frame can be leaned towards the middle, the two bottom horizontal bars 111 of the bottom bracket 11 respectively include two pivotally connected horizontal struts 110 , and between the two horizontal struts 110 of the same bottom horizontal bar 111 The connection in the middle part is connected by the pivoting piece 112, and the pivoting piece 112 is respectively pivotally connected to the outer sides of the two horizontal struts 110 to connect the two horizontal struts 110. When the chair frame is folded, the two horizontal struts 111 on the bottom surface The cross strut 110 can be folded downward under the action of the connection of the pivot piece.

In this embodiment, as shown in the figure, in order to make the connection between the bottom bracket 11 and the armrest frame 12 more stable, the chair back of the chair frame is more reliable, and an auxiliary cross bar 14 is arranged at the rear of the chair frame to pivotally connect the two armrest frames 12. At the rear, the auxiliary cross bar 14 is arranged above the rear bottom cross bar 111. The auxiliary cross bar 14 is also pivotally connected between the two armrest frames 12. Above the rear bottom cross bar 111, the two outer sides of the auxiliary cross bar 14 The ends are respectively pivotally connected under the vertical feet 121 on both sides of the armrest frame 12, and the auxiliary crossbar 14 also includes two pivotally connected crossbars 141 pivotally connected in the middle. The same two horizontal struts 141 are connected through the pivot joint at the middle joint. Because the auxiliary horizontal strut 14 is located above the bottom horizontal strut 111, the horizontal strut 141 and the horizontal strut 110 are all pivotally connected in the middle, so the bottom surface The cross bar and the auxiliary cross bar 14 are connected by an I-shaped connecting piece 15 at the middle joint, and the two cross struts 141 of the auxiliary cross bar 14 and the two cross struts 110 of the bottom cross bar 14 are respectively connected on the I-shaped connection. Four connecting ends 151 of the sheet 15, so that the auxiliary cross bar 14 is connected above the bottom cross bar 111, and is also connected and supported by the I-shaped connecting piece 15.

When folding the grandstand chair of the present utility model, as shown in Fig. 2 to Fig. 4, firstly, the backrest rod 13 is retracted downward to the upper end of the armrest frame 12, and the armrest frames 12 on both sides are to be combined and leaned against. It is only necessary to fold down the bottom cross bar 111 and the auxiliary cross bar 14 respectively, as shown in Figure 3, make the bottom cross bar 111 and the auxiliary cross bar 14 retract inward and close together, and lean against the two armrest frames Between 12, the folding of the chair frame is finally realized, as shown in Figure 4.

Conversely, when the grandstand chair is to be used, when the folded grandstand chair is unfolded, as long as the bottom cross bar 111 and the auxiliary cross bar 14 are unfolded at the same time, the unfolded support is located between the two armrest frames 12, and the two armrest frames 13 are erected upwards, thereby Just unfold the whole chair frame, match the upper cushion and backrest cloth, and the grandstand chair can be placed directly on the steps of the grandstand for use.

The grandstand chair of the utility model is convenient to unfold and store. When in use, it can be unfolded and used directly. When not in use, it can be folded and folded. It does not need to be disassembled and installed separately. The operation is simple and easy, the structure is simple, and it can be easily folded into a small volume. , Easy to use and collect.

The above-mentioned embodiments and drawings do not limit the product form and style of the present utility model, and any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present utility model.
