detailed description of the invention
With reference to Fig. 1-3, the lateral plan of the sitting-lying double-purpose seat that Fig. 1 provides for first embodiment of the invention; Fig. 2 is sitting-lying double-purpose seat in Fig. 1 front view under functional seat state; Fig. 3 is sitting-lying double-purpose seat in Fig. 1 front view under sleeping berth functional status.
As Figure 1-3, the sitting-lying double-purpose seat in the first embodiment of the present invention comprises sleeping berth 1, backrest 2, sleeping berth locking 3 device and backrest blocking devices 4.
Sleeping berth 1 comprises paving body 11, sleeping berth mount pad 12 and paving axle 13; Sleeping berth mount pad 12 is realized the support to sleeping berth 1 by being arranged on the body of wall at sleeping berth 1 two ends, and paving axle 13 one end are embedded in sleeping berth mount pad 12, and the other end is embedded at paving body 11 side ends.
The edge portion of the seat face of the lower end of backrest 2 and sleeping berth 1 is hinged; After backrest 2 is amounted to sleeping berth 1, backrest 2 is positioned at the bottom of sleeping berth 1, the sealed sleeping berth 1 of backrest blocking device 4 and backrest 2, and sleeping berth blocking device 3 locks sleeping berth 1, and this sitting-lying double-purpose seat uses as sleeping berth.
Sleeping berth 1 drives after backrest 2 upsets, and backrest 2 is positioned at the top of sleeping berth 1, and sleeping berth blocking device 3 locks sleeping berth 1, upwards digs and opens backrest 2, and this sitting-lying double-purpose seat uses as seat.
In the present embodiment, paving body 11 is made up of sectional materials cage, and the one side of paving body 11 is the sleeping berth face of Soft Roll material, for passenger's rest that couches.The another side of paving body 11 is the seat face of Soft Roll material, for passenger's rest that is seated.Position near edge on the seat face of paving body 11 is provided with supporting seat 14, the lower end of supporting seat 14 is fixedly connected with the edge of paving body 11, the lower edge of the upper end of supporting seat 14 and backrest 2 is hinged, and backrest 2 can rotate around jointed shaft, realizes upwards digging or fastening with paving body 11 of backrest 2.The dependence face of the backrest 2 after opening is greater than 90 degree with the angle of the sleeping berth face of sleeping berth 2.
Paving axle 13 has multiple with the connection mode of sleeping berth mount pad 12 and paving body 11, for example, sleeping berth mount pad 12 is for having the tabular body structure of axis hole, one end of paving axle 13 coordinates with the axis hole on sleeping berth mount pad 12 is movable, the other end of paving axle 13 is fixedly connected with paving body 11 two ends, paving body 11 can rotate with paving axle 13 in the mounting hole of sleeping berth mount pad 12, and then realizes 180 degree rotations of paving body 11.In addition, one end of paving axle 13 can also be fixed on sleeping berth mount pad 12, paving body 11 two ends have axle sleeve, and the other end of paving axle 13 coordinates with the axle sleeve activity at paving body 11 two ends, and then paving body 11 can rotate around paving axle 13, can realize equally 180 degree rotations of paving body 11.
Sleeping berth blocking device 3 can adopt various ways, as adopts the mode of two hooks that sleeping berth 1 is locked, and when sitting-lying double-purpose seat provides sleeping berth function, a hook is hung on the hanging ring on sleeping berth, by fixing sleeping berth 1.In the time that sitting-lying double-purpose seat provides functional seat, open hook, sleeping berth 1 turns over after turnback, and another hook is hung on hanging ring, by fixing sleeping berth 1.
Backrest blocking device 4 also can adopt various ways to realize several functions, for example, backrest blocking device 4 can, in the time that backrest 2 and sleeping berth 1 fasten, be locked as one by backrest 2 and sleeping berth 1, when backrest 2 turn to sleeping berth 1 bottom, can avoid backrest 2 to open under the effect of gravity.In addition, on the basis of such scheme, can also be in the time that backrest 2 be opened, backrest 2 and sleeping berth 1 are locked fixing, avoid backrest 2 to topple over to sleeping berth 1.The concrete structure of backrest blocking device 4 also can have various ways, and as the mode that adopts hook locks backrest 2 and sleeping berth 1, this is no longer going to repeat them.
The sitting-lying double-purpose seat that the present embodiment provides is when using in the lower berth of passenger train, a sleeping berth mount pad 12 is arranged on the suitable wall 10 in outside, another sleeping berth mount pad 12 is arranged on the side wall 20 of inner side, and the paving axle 13 at paving body 11 two ends is arranged on respectively on sleeping berth mount pad 12.
The switching process of the sitting-lying double-purpose function of the sitting-lying double-purpose seat providing below in conjunction with accompanying drawing 1-3 explanation the present embodiment:
In the time that passenger need to couch rest, as shown in Figure 2, this sitting-lying double-purpose seat provides sleeping berth function, sleeping berth blocking device 3 locks sleeping berth 1, the sleeping berth of sleeping berth 1 faces up, and backrest 2 and sleeping berth 1 fasten and be positioned at the bottom of sleeping berth 1, and backrest blocking device 4 is by sealed to backrest 2 and sleeping berth 1.Passenger couches and has a rest on the sleeping berth face of paving body 11.
When passenger's rest that need to be seated, this sitting-lying double-purpose seat provides functional seat, as shown in Figure 3, open sleeping berth blocking device 3, then the sleeping berth 1 that overturns, sleeping berth 1 drives backrest 2 Rotate 180 degree, and the sleeping berth of sleeping berth 1 is faced down, backrest 2 turn to the top of sleeping berth 1, and sleeping berth blocking device 3 locks sleeping berth 1.
Open backrest blocking device 4, upwards invertible back support 2, backrest 2 rests on partitions 30, the dependence face of backrest 2 is greater than 90 degree with the angle of the seat face of sleeping berth 1, in order to make taking of passenger more comfortable, this angle can be arranged to 100 degree-110 degree, and the leading surface of backrest 2 can be designed to the cambered surface of human spine shape.
The sitting-lying double-purpose seat that first embodiment of the invention provides, sleeping berth 1 is realized upset by paving axle 13, sleeping berth blocking device 3 can be locked in sleeping berth 1 two functional statuses, and backrest 2 can be amounted to, overturns and lock, thereby the sitting-lying double-purpose seat that the present embodiment provides, can realize sleeping berth function and functional seat, for passenger provides two kinds of selections, improve the traveling comfort of taking.
On the basis of the sitting-lying double-purpose seat technical scheme providing in first embodiment of the invention, can also be improved further this sitting-lying double-purpose seat, below in conjunction with the further improvement project of brief description of the drawings sitting-lying double-purpose seat.
With reference to figure 4 and Fig. 5; The head rest that Fig. 4 provides for second embodiment of the invention is at the structural representation of pressing; Fig. 5 is head rest in Fig. 4 structural representation at tip-up state.
As shown in Fig. 1,4 and 5, sitting-lying double-purpose seat also comprises head rest 5, and head rest 5 is arranged on the position of backrest 2 tops, and the upper edge of the backrest 2 after opening is near the lower edge of head rest 5.Head rest 5 can adopt conventional headrest structure, for improve passenger be seated have a rest traveling comfort.
Further, head rest 5 comprises head rest main body 51, head rest mount pad 52, pressurized air spring 53 and the head rest locking bar 54 of arc.
Head rest mount pad 52 can be arranged on body of wall and realize the support to head rest 5, and the bottom of head rest mount pad 52 is provided with lockhole.Particularly, head rest mount pad 52 is arranged on (shown in Fig. 1-3) on partitions 30, the upper end of the upper end of head rest main body 51 and head rest mount pad 52 is hinged, one end of pressurized air spring 53 and head rest mount pad are hinged near the position of upper end, and the bottom of the other end of pressurized air spring 53 and head rest main body 51 is hinged;
