Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
embodiment 1
Fig. 1 is the structural representation of the utility model folding seat.As shown in Figure 1, folding seat 1 comprises seat support 10, rotating fore-stock 20 and the after-poppet 30 being connected to seat support 10 both sides, with the rotating foot support 40 that is connected of seat support 10 and back braces 50.The retractable supports 60 for regulating foot support 40 angle is provided with between fore-stock 20 and foot support 40; Back braces 50 is provided with an auxiliary support frame 70.
As shown in Figure 2, seat support 10, fore-stock 20, after-poppet 30, foot support 40, back braces 50 and auxiliary support frame 70 are preferably U-shaped structure stand, and it comprises bottom bar 110 and is arranged at the side rod 120 at bottom bar 110 two ends respectively.Wherein, seat support 10 side rod 120 near bottom bar 110 by bending, make itself and two side rod 120 place planes form that angle of looking like, as shown in Figure 3.
Seat support 10, fore-stock 20, after-poppet 30, foot support 40, back braces 50 and auxiliary support frame 70 can be obtained by welding or riveting, and also can be obtained by square tube or bending circular pipe.
Two side rods of after-poppet 30 are respectively arranged with the angle demodulator 80 for regulating back braces 50 angle.
As shown in Figure 4, Figure 5, angle demodulator 80 comprises the first body of rod 810, second body of rod 820 and cross bar 830.Two second bodies of rod 820 are separately fixed at cross bar 830 two ends, and two first bodies of rod 810 are connected with cross bar 830 two ends are rotating respectively, and first body of rod 810 can be stuck with the junction of cross bar 830.First body of rod 810 is positioned at the outside of same one end second body of rod 820.
Two first bodies of rod 810 are connected on two side rods of after-poppet 30 respectively by the first connecting hole 811 is rotating.Second connecting hole 821 is rotating is respectively connected on two side rods of back braces 50 for two second bodies of rod 820.
In addition, angle demodulator 80 can be the angle demodulator of tables and chairs in prior art.
On seat support 10, foot support 40 and back braces 50, cover has chair cloth.
Wherein, two side rod ends of back braces 50 are connected on two side rods of seat support 10 respectively by connector 101.Two side rod ends of seat support 10 are connected with two side rod ends of foot support 40 respectively by connector 101.
Wherein, two side rods of fore-stock 20 are connected with two side rods of seat support 10 by the second connector 102.Fore-stock 20 can be fixedly installed support bar 210 between two side rods.Two side rod ends of after-poppet 30 are connected on two side rods of seat support 10 respectively by connector 101.
In addition, folding seat 1 also comprises the first handrail 910 and the second handrail 920.First handrail 910 is connected with two side rod ends of fore-stock 20 respectively by the second connector 102 with one end of the second handrail 920.The other end is connected on two side rods of back braces 50 respectively by the second connector 102.
Further, wear-resisting plastic can also be provided with on fore-stock 20, after-poppet 30 and auxiliary support frame 70.Wherein, the wear-resisting plastic on fore-stock 20, after-poppet 30 is arranged at the junction of side rod and bottom bar, forms triangle stable support structure.Meanwhile, fore-stock 20, the square tube of after-poppet 30 or pipe size is made large compared with other supports.Make chair stability increase like this, not easily turn on one's side.
As shown in Figure 6, the side rod end of auxiliary support frame 70 is connected with two side rods of back braces 50 are rotating respectively by the 3rd connector 103 syndeton of back braces 50 and auxiliary support frame 70.3rd connector 103 can be triangular form articulated joints, forms stable triangular structure.Triangular form articulated joints can be one-time formed by engineering plastics, even if be subject to unexpected cross force like this, and also can not fracture damage.
When chair is in flat condition, auxiliary support frame 70 can play the effect increasing load-bearing, prevents back braces from rupturing when higher load-bearing.
As shown in Figure 7, retractable supports 60 comprises the first stay pipe 610 and the second stay pipe 620.Wherein, the external diameter of the first stay pipe 610, slightly larger than the second stay pipe 620, makes the second stay pipe 620 can slide in the first stay pipe 610.And on the first stay pipe 610, be provided with position, at least two holes 611, the outer wall of the second stay pipe 620 is provided with at least one projecting elastic parts 621 matched with position, hole 611.First stay pipe 610 and the second stay pipe 620 passing hole position 611 coordinate the structure that can be formed and be similar to Folding umbrella expansion link with projecting elastic parts 621.
When projecting elastic parts 621 match from different positions, hole 611, foot support 40 can form different angles.As when needs chair is in normal condition, projecting elastic parts 621 coordinate with the position, hole 611 near foot support 40 one end on the first stay pipe 610, projecting elastic parts 621 eject and block from position, hole 611, and the foot support 40 of chair can not automatically be upwarped under the effect of bed surface pulling force.In like manner, when needs foot support 40 upwarps certain angle, projecting elastic parts 621 coordinate with the position, hole 611 away from foot support 40 one end on the first stay pipe 610.Such projecting elastic parts 621 coordinate from the position, hole 611 of diverse location on the first stay pipe 610 and foot support 40 just can be regulated to make itself and ground form different angles, to adapt to the different needs of people.Wherein, projecting elastic parts 621 can be elasticity hoodle.
In addition, one end of the second stay pipe 620 is connected by the second connector 102 is rotating with the side rod of fore-stock 20.The other end is bushing in first stay pipe 610 one end.The other end of the first stay pipe 610 is connected with foot support 40 is rotating by connector 101.Wherein, connector 101 can be articulated joints, and the second connector 102 can be rivet.
The utility model can be regulated separately the angle of foot support or back braces by retractable supports 60 and angle demodulator 80, also can be regulated the angle of foot support and back braces simultaneously, forms different using states, meets different needs, as shown in Figure 8, Figure 9.In Fig. 9, after being at chair the state set level, the former foot support for taking pin can be continued to upwarp, forming the state of a semi-lying.
embodiment 2
The difference of the present embodiment and embodiment 1 is, the retractable supports 60 between fore-stock 20 and foot support 40 can be changed to angle demodulator.All the other structures are identical with embodiment 1.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical problem; even if some making on the utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
