Description
Technical field
The utility model relates to the folding seat that a kind of metal tube constitutes.
Background technology
The Foldable handrail chair that existing metal tube constitutes comprises chair frame and cloth cover two parts.For example, Foldable handrail chair a kind of simple in structure shown in Figure 1: its chair frame is by vertical rod after two 1, four runners 2, four side levers 3, bar 4 after two, two preceding bars 5, two 6, two sliding sleeves of preceding bar cover 7, two cover pieces 8, two bars 9,10 and two spacer pins 11 of bar cover are formed after two; Its cloth cover is made up of seat cushion 12 ' and back cushion 13 '.
Please referring to Fig. 2: a runners 2 is installed in the lower end of vertical rod 1 after every, sliding sleeve 7 of middle part suit, and bar cover 10 behind a spacer pin 11 and is installed on top.
A runners 2 is respectively installed in the lower end of two preceding bars 5, and the middle part is hinged, and a preceding bar cover 6 is installed in the bending place on top.
Two side lever 3 middle parts in chair frame left side are hinged, and wherein the sliding sleeve 7 in the back vertical rod 1 of the upper end of first side lever 3 and chair frame left side is hinged, and the runners 2 of lower end and first preceding bar 5 lower end is hinged; The preceding bar cover 6 on the upper end of second side lever 3 and second preceding bar 5 top is hinged, and the runners 2 of lower end and vertical rod 1 lower end, back, chair frame left side is hinged.
Two side lever 3 middle parts on chair frame right side are hinged, and wherein the sliding sleeve 7 in the vertical rod 1 is hinged behind the upper end of the 3rd side lever 3 and the chair frame right side, and the runners 2 of lower end and second preceding bar 5 lower end is hinged; The preceding bar cover 6 on the upper end of the 4th side lever 3 and first preceding bar 5 top is hinged, and the runners 2 of vertical rod 1 lower end is hinged behind lower end and the chair frame right side.
The front end of every bar 9 is installed a cover piece 8, and the rear end is hinged on the chair frame with on the back bar cover 10 in the rear flank vertical rod 1.The preceding bottom of cover piece 8 can be connected in corresponding preceding bar 5 upper ends.
Please referring to Fig. 3: the main body of back bar cover 10 is a straight tube 101, and back vertical rod 1 is inserted in the pore 102 of this straight tube 101.A jut 103 is extended in the front side of this straight tube 101, leaves a groove 104 on this jut 103, has a pair of through hole 105 on two sidewalls of this groove 104.
Axis hole is established in the rear end of bar 9, and short pin 106 passes through hole 105 on these groove 104 sidewalls and the axis hole on the bar 9, bar 9 is articulated in the groove 104 of back bar cover 10.When harvesting, back bar cover 10 can move up along back vertical rod 1; And in user mode, spacer pin 11 can withstand the lower surface of back bar cover 10, makes back bar cover 10 can not continue to move, thus the upper end of bar 5 before the cover piece 8 of assurance bar 9 front ends can stably be stuck in.
Because vertical rod 1 move up after when harvesting, sliding sleeve 7 can be with the upper end edge of corresponding side lever 3 and back bar 4, and crosses spacer pin 11, please referring to Fig. 4: the both sides of the pore 702 of the straight sections 701 of sliding sleeve 7 must be left and the spacer pin 11 corresponding slot to make way 703 of appearing.
