Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
As Fig. 1 to Fig. 2, a kind of convenient chair of having a rest, comprise base 1, base 1 is positive pentalpha, and it comprises the equal support of five length, and one, support is provided with wheel; Base 1 is fixedly connected with back shaft 2 lower end, back shaft 2 upper end connecting trays 3, and back shaft 2 is provided with gas bar spring assembly, can regulate height.Pallet 3 is provided with cushion 4, pallet 3 left and right sides is provided with handrail 5, and pallet 3 rear portion is provided with backrest 6, and backrest 6 bottom inwardly falls into afterwards by certain radian and forms space 11.Two swing arms 71 are provided with in the front end bilateral symmetry of cushion 4, the front end of two swing arms 71 is connected by a support, the position of swing arm 71 rear end and both sides, cushion 4 front end is hinged, the support that swing arm 71 front end connects is hinged with leg rest cushion 9, swing arm 71 is turned over and is made leg rest cushion 9 receive space 11 place to cushion 4 rear, and swing arm 71 overturns forward and is fixed on certain position by ratchet hornwork 8 and has a rest to make leg rest cushion 9 play a role to realize leg rest.It is hinged with the support being connected two swing arm 71 front ends that leg rest cushion 9 comprises the first cushion 91, first cushion 91, second cushion 92 one end and the first cushion 91 hinged, the other end be arranged on " U " shape slide block in swing arm 71 93 by a hinge.After deployment, length can reach the heel place of user in swing arm 71, supports more effective and comfortable, and due to heel place, to there is blood vessel less, also less to human vas compressing, to healthy and beneficial.And after leg rest cushion 9 is launched completely, make to become very large to the supporting surface of pin, further reduce the compressing to blood vessel, make people more comfortable when rest.
As shown in Figures 3 to 5, on pallet 3, be also provided with bracket under cushion 4, bracket comprises two fixed supports 72 being arranged on cushion 4 both sides, connected by fixation steel plate 10 between two fixed supports 72, fixation steel plate 10 is fixedly connected with by screw with pallet 3.The front end of two fixed supports 72 is provided with axle bed 89, axle bed 89 is fixed with axle bottom 81, axle bottom 81 is fixed with axle enclosing cover 86, axle bottom 81 is connected by the first bearing pin 87 with axle enclosing cover 86, between axle bottom 81 and axle enclosing cover 86, the central area in space is provided with screens sheet 82, swing arm 71 rear end forms the ratchet 83 of periphery with unidirectional tooth 831, ratchet 83 stretches between axle bottom 81 and axle enclosing cover 86, screens sheet 82 and ratchet 83 wheel face are affixed, and ratchet 83 is rotationally connected with the first bearing pin 87 with the center of both screens sheets 82 is common; Between axle bottom 81 and axle enclosing cover 86, the edge region in space is provided with the ratchet 84 coordinated with ratchet 83, screens sheet 82 and the elastic component 85 coordinated with ratchet 84, described ratchet 84 is hinged by the second bearing pin 88 and axle bottom 81, axle enclosing cover 86, the trend that ratchet 84 keeps under the effect of elastic component 85 and screens sheet 82, ratchet 83 outer peripheral edge offset; Described screens sheet 82 is overall rounded, and the periphery of screens sheet 82 is provided with between the first fan-shaped breach 822, second breach 823, first breach 822 and the second breach 823 and forms stopper 824; Described ratchet 83 is provided with the shifting block 832 protruding from ratchet 83 wheel face, stir screens sheet 82 when shifting block 832 to be in the first breach 822 and to rotate with swing arm 71 to rotate, the outer peripheral edge 821 of the screens sheet 82 beyond the first breach 822 and the second breach 823 protrudes from unidirectional tooth 831 outer rim thus ratchet 84 and unidirectional tooth 831 is thrown off, and ratchet 84 enters into after in the second breach 823 and then engages with the unidirectional tooth 831 at diverse location place.
As shown in Fig. 6 to Figure 17, due to the radian of the second breach 823, can hold 4 unidirectional teeth 831, thus, swing arm 71 has four gears, can be fixed in corresponding four angles.When swing arm 71 is at rounding state, the screens sheet outer peripheral edge 821 beyond ratchet 84 and the first breach 822 and the second breach 823 offsets, and makes ratchet 84 and unidirectional tooth 831 depart from fastening state.When needs are opened foot-operated, rotate swing arm 71, when turning to certain angle, the shifting block 832 be positioned on ratchet 83 end face offsets with the stopper 824 be positioned on screens sheet 82, now be rotated further swing arm, stopper 824 is stirred screens sheet 82 and is rotated together thereupon, until ratchet 84 enters in the second breach 823 and engages with unidirectional tooth 831, now swing arm 71 is in the position of first grade, and the angle that namely swing arm 71 is opened reaches maximum.Due to the setting of ratchet positioner 8, the direction that now angle reduced in the past only regulates swing arm 71, is adjusted to the most applicable angle of oneself having a rest always.When needs draw swing arm 71 in, counter-rotation swing arm 71 to fourth speed position, now be rotated further swing arm 71, the shifting block 832 be positioned on ratchet 83 wheel face can offset with the other end of the first breach 822 on screens sheet 82, now being rotated further swing arm 71 can drive screens sheet 82 to rotate together, during to certain angle, the outer peripheral edge 821 of the screens sheet 82 beyond the first breach 822 and the second breach 823 can offset with ratchet 84, make ratchet 84 and unidirectional tooth 831 depart from engaging, continue draw swing arm 71 in and leg rest cushion 91 is placed in cushion rear position place.
In order to make screens sheet, ratchet and ratchet be fixed, not easily depart from, the width and the screens sheet 82 that arrange gap between axle bottom 81 and axle enclosing cover 86 are suitable with ratchet 83 thickness sum; Between axle bottom 81 and axle enclosing cover 86, the width in gap is suitable with the thickness of ratchet 84.Ratchet 84 is bidentate structure, and the spacing between bidentate and the spacing between unidirectional tooth 83 are suitable, and this design makes that engaging is between the two more firm not easily to depart from.Shifting block 832 is made up of to in-flanges the punching on ratchet 83 end.Because shifting block 832 is made up of to in-flanges punching, the shifting block that the modes such as its relative welding are obtained has high intensity, and not fragile, cost is also lower comparatively speaking.Swing arm 71 also can be set to telescopic swing arm, the space taken is reduced on the one hand further when rounding state, the length making on the other hand user swing arm can be regulated voluntarily to stretch out according to the length of the height of oneself and leg, makes it more effective and comfortable to the support of leg.
Need by button or switch ability adjusting angle relative to some support foot rests on the market, the utility model does not need to operate change and the fourth gear location that any button just can realize angle, simple and convenient, reduces the manipulation strength of user.
