Detailed description of the invention
embodiment one
As shown in Fig. 1 ~ 4, the seat elevating folding mechanism of the present embodiment comprises two elevating levers 1 be arranged in parallel, elevating lever 1 comprises pillar 11, is sleeved on the lifting tube 12 on pillar 11, and locks 13 for the position of differing heights position lifting tube 12 being locked in pillar 11.Position lock 13 is a latch, and on pillar 11, axially-aligned has a rows of openings, and lifting tube 12 also has a perforate, the adjustment position of lifting tube 12 on pillar 11, and make their perforate contraposition, insertion position lock 13, the location of lifting tube 12 on pillar 11 can be realized, as shown in Figure 3,4.
The top of lifting tube 12 is provided with saddle 14, and bottom is provided with hinge 15.Saddle 14 is the supporting plate being horizontally fixed on lifting tube 12 opposite side, front end upwards bends.Hinge 15 is arranged on and is positioned on the reclinate arc mounting blocks 16 of lifting tube 12 opposite side, and mounting blocks 16 longitudinally has an axis hole, and hinge 15 interts in this axis hole, and two ends are exposed.
Elevating folding mechanism also comprises the arm support that the transposition arm 2 that is hinged to X-shaped by two middle parts is formed, each transposition arm 2 of arm support is made up of two connecting rods be arranged in parallel 21, connecting rod 21 one_to_one corresponding of two transposition arms 2 is connected to form two relative X-shapeds, as shown in Figure 1, 2.The lower end pin of connecting rod 21 is provided with hinge cover 22, formation articulated structure suitable with the hinge 15 on lifting tube 12.
Two upper end pin of arm support are connected with chair surface 3 both sides respectively, two upper end pin of arm support away from, after driving chair surface 3 to be deployed into level, support is on saddle 14, upwards carries chair surface 3, drive two upper end pin of arm support to draw in, realize the folding gathering of seat.Chair surface 3 can fold, and chair surface 3 can be a soft seat cushion, also can be the seat board in Fig. 1,2, and seat board is made up of the plate 31 that two pieces of sides are hinged.At least one plate 31 is provided with the butt strip stretching to offside in hinged place, when chair surface 3 is deployed into level, described butt strip is overlapped on the plate 31 of offside, ensures can not sink in the middle part of seat board 2.
Seat board both sides are hinged with two upper end pin of arm support respectively, concrete structure is: the both sides of seat board bottom surface are longitudinally provided with a jointed shaft 32 respectively, two connecting rods of transposition arm are sleeved on the two ends of jointed shaft 32 by the hinge cover 23 that its upper end is arranged, the upper end of two of each transposition arm connecting rods 21 is connected together by jointed shaft 32, when chair surface 3 launches, the jointed shaft 32 between two connecting rods 21 is hooked in the bending of saddle 14 front end, makes structure more stable.
Described in above hinged with two upper end pin of the arm support respectively structure in seat board both sides is not limited to, as jointed shaft 32 can directly be fixed between two connecting rods of transposition arm, by arranging two relative hinge covers respectively in both sides, seat bottom surface, the hinged of two upper end pin of seat board and arm support also can be realized.
Described hinge in the utility model on elevating lever 1 or the distance range between hinge cover and saddle 14 comparatively suitable at 10 ~ 60cm, the too short elevating folding laser intensity of distance is inadequate, easily rocks.
Fig. 5 is the second embodiment of the utility model elevating lever: as shown in the figure, and elevating lever 1 is an air pressure or hydraulic pressure telescopic rod, and lifting tube 12 is sleeved on telescopic rod regularly with its reduction synchronization lifting.
Fig. 6 is the third embodiment of the utility model elevating lever: as shown in the figure, and the elevating lever in this embodiment is substantially identical with the lifting rod structure in embodiment one, and difference is the structure of lifting tube 12, below single lifting tube 12 introduced in this embodiment lower.
In this embodiment, the saddle 14 being located at lifting tube 12 top be one be fixed on lifting tube 12 side, stretch between two elevating levers, supporting spring that front end bends to lifting tube 12 opposite side, the front top of supporting spring bending raises up, for hooking the jointed shaft 32 between two small ends after chair surface 3 launches.What be located at lifting tube 12 bottom is hinge cover 16, and concrete structure is: the both sides of lifting tube 12 are relatively fixed two installation sheets, and the installation sheet beginning is provided with perforate and is hinge cover
16, accordingly, to hinge overlap just should be corresponding on the 16 adaptive lower end pin forming two connecting rods of the transposition arm of articulated structure hinge is set, as arranged convex cylinder on the pin of connecting rod lower end.
