Detailed description of the invention
Embodiment, refers to shown in Fig. 1 and Fig. 2, a kind of Portable foldable chairs of the present invention, comprises seat 1, the chair back 2, handrail 3 and leg 4.The chair back 2 and handrail 3 are rotationally connected with on seat 1 side respectively, and leg 4 is rotationally connected with the back side of seat 1.
Side is provided with connecting portion to seat 1, concrete, with reference to figure 3, is square structure for seat 1, a side is horizontally outward extended with 2 chair back connecting portions 11, and two adjacent with it sides are horizontally outward extended with 2 handrail connecting portions 12 respectively.Chair back connecting portion 11 comprises two of be arrangeding in parallel monolithic 111 with holes, and each monolithic 111 distal male with holes forms the block body 112 for limiting the chair back 2 angle of inclination.With reference to figure 4, the chair back 2 is extended with the rotating mechanism 21 coordinated with chair back connecting portion 11 downwards, and rotating mechanism 21 also comprises two of be arrangeding in parallel monolithic 211 with holes.Composition graphs 2 and Fig. 7, monolithic 112 and monolithic 211 intersect and coordinate to make hole overlap, one rotating shaft 5 through the hole of chair back connecting portion 11 and rotating mechanism 21 to be connected seat 1 and the chair back 2, the chair back 2 phase countershaft 5 rotates, the length of rotating mechanism 21 matches with the thickness of seat 1, with the front making the chair back 2 can turn to seat 1 of fitting completely when folded state.In a state of use, the chair back 2 turns to and abuts block body 112, is blocked and cannot continue to rotate, thus remain on fixing position by block body 112.Axially there is relative motion in rotating shaft 5 between seat 1 and the chair back 2 in arranged in a crossed manner the preventing of monolithic 112 and monolithic 211, makes connection more firm stable.
With reference to figure 5, handrail 3 bottom is bent to form kink 31, and kink is outward extended with the rotating mechanism 32 coordinated with handrail connecting portion 12.Composition graphs 2 to Fig. 3 and Fig. 7, seat 1 is connected with rotating mechanism 32 through handrail connecting portion 12 by a rotating shaft 6 with handrail 3, and handrail 3 phase countershaft 6 rotates.On same side, at least one handrail connecting portion 12 distal male forms the block body 121 for limiting handrail 3 angle of inclination, and in a state of use, handrail 3 turns to and abuts block body 121, is blocked and cannot continue to rotate, thus remain on fixing position by block body 121.Kink 31 can be specifically the bending of 90 degree, and its length matches with the thickness of the chair back 2, to make way for the chair back 2 in a folded configuration, can turn to the chair back 2 of fitting completely.The handrail 3 of both sides is symmetrical arranged, and connect after folding and cover the chair back 2 completely, namely seat 1, the chair back 2 and two handrails 3 closely cooperate, and present a stacked state.The structure of handrail connecting portion 12 and rotating mechanism 32 and chair with back connecting portion 11 and rotating mechanism 21 similar, intersect by monolithic and coordinate, not in this to go forth.
Two handrails 3 stretch out near one end of the chair back 2 to make its length be longer than seat 1, the part extended is positioned at outside seat 1 and the chair back 2 when folding, two handrails 3 this extension part respectively symmetrically in be recessed into U-shaped, and be combined to form a handle 33, be convenient to catching.Add distance after handrail, so both can design handle 15, can contact with standing with behind when opening again, avoiding rocking of handrail.
With reference to figure 2, leg 4 includes a pair first legs 41 and a pair second legs 42 that diagonally arrange.With reference to figure 6, for the first leg 41, its end is extended with rotating mechanism 411 with holes.With reference to figure 3, the back side of seat 1 is provided with the first leg connecting portion 13 matched with the first leg 41 and the second leg connecting portion 14 matched with the second leg 42, for the first leg connecting portion 13, includes two monolithics 131 with holes.Composition graphs 2, Fig. 7 and Fig. 8, rotating mechanism 411 to insert between two monolithics 131 and hole is overlapped, and is fixed by hinge.The summation of the first leg 41 and the first leg connecting portion 13 length equals the summation of the second leg 42 and the second leg connecting portion 14 length, wherein the length of the second leg connecting portion 14 is longer than the first leg connecting portion 13, and the diameter compatible of the length increased and the first leg 41 closes, to make way for the first leg 41 under closed state.Under closed state, two the first legs 41 fit in the back side of seat 1 parallel to each other, and two the second legs 42 are parallel to each other and to fit across the first leg 41 with the first leg 41.4 legs of the present invention independently rotate mutually, and can according to circumstances and respectively adjust different angles when using state for the ground of injustice, practical, steadiness is high; When folded state due to the design of its length, can be fully folding, save space on the one hand, foldable structure is compact, not fragile on the other hand.
What deserves to be explained is, the quantity of above-mentioned connecting portion, rotating mechanism, leg and monolithic all just illustrates, does not regard this as a limit, and also can arrange other quantity respectively according to actual conditions.In addition, above-mentioned each rotating shaft is also by conventional methods such as jump ring, nut, packing ring, Design of Screw Threads and lock between individual each connecting portion and rotating mechanism.
Above-described embodiment is only used for further illustrating a kind of Portable foldable chairs of the present invention; but the present invention is not limited to embodiment; every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all fall in the protection domain of technical solution of the present invention.
