pillar

37 and 39 near four angles, and following place respectively establishes a pillar 38 on plate A, when open at plate A end, pillar 39 on the plate B matches with the hole 40 on the plate A, and the pillar 38 on the plate A matches with the hole 41 on the plate B.After plate A opened, plate A and plate B went up and

pillar

37,38 and 39 can land as supporting.In addition, plate A goes up also has a hole 36, when plate A opens, right pedal 43 is through in this hole 36, a wheel 11 respectively has been installed on the following exterior angle of plate A and B, beam 44 corresponding sections in plate A and body frame rear portion 3 are provided with a clip 18 (clip is as shown in figure 14), in plate D and body frame front portion 2 on the cant beam corresponding section also be provided with a clip 19, on the crossbeam on the bicycle front fork 15 14, fix a clip 16 (clip 16 is as shown in figure 13).Plate C is suspended on the cantilever 6 on shelf 5 right sides, and this cantilever 6 can be established one, also can establish a plurality ofly, and present embodiment is provided with four, correspondingly is provided with four slotted eyes 30 on plate C, and cantilever 6 matches with slotted eye 40.The outer end edges of cantilever 6 upwards bends up, to prevent the outside landing of plate C.When bicycle normally used, plate C can be moved to the left and be close to shelf 5 right sides and right axletree to reduce car rear portion width.Plate B and plate C and tailgate E coupling end are provided with a plurality of recesses 35 and pin-and-hole 45, and tailgate E left side is provided with a plurality of recesses 31 and pin-and-hole 32 with plate B coupling end, is provided with a plurality of darker recesses 33 and cotter way 34 on its right side and plate C coupling end.Left end recess 31 matches with the recess 35 of plate B, and plate B and tailgate E are hinged together by pin rod 49, the recess 33 of right-hand member and the recess 35 on the plate C match, and by pin rod 48 plate C and tailgate E are hinged together, and pin rod 48 also can be along 34 sway of the cotter way on the tailgate E.

Referring to Fig. 9～12, the retractable movable leg 7 of a length and 8 respectively are installed, this

movable leg

7 and 8 hinged with plate A and plate D respectively on plate A and plate D by hinge.

Movable leg

7 and 8 can forward the upright position to from mutual equality position with respect to plate A and plate D.And can be fixed on this position.

Movable leg

7 and 8 is made up of pipe 26, bar 27 and crossbeam 28, captives joint with two pipes 26 respectively in crossbeam 28 two ends, and bar 27 can move in pipe 26 by finger 29 and be fixing.One retractable Convenient table 9 and 10 respectively have been installed on plate B and plate C, and this Convenient table 9 and 10 is made up of plate 20, pipe 21 and bar 22, and bar 22 can move in pipe 21 by finger 23 and be fixing.Plate 20 was both captiveed joint with plate B, plate C, also captives joint with two pipes 21, thus the supporting capacity of reinforcement Convenient table.This

movable leg

7,8 and Convenient table 9,10 are all made multi-joint telescoping, so that regulate the height of leg.As when becoming chaise longue, movable leg 7 will be stretched out longer, and plate A, B are tilted.

How describe multifunctional folding bicycle of the present utility model now uses.Shown in 1, when the utility model used as Regular Bicycle, High-foot hinge 4 was not opened, and was stuck in (see figure 5) on two screw rods 25 on the lower inclined beam left side that is located at the body frame front and rear part respectively with clip 24.The front and rear part 2,3 of bicycle is fixed and forms an integral body.At this moment, the plate A and the plate D of shelf 5 left and right sides do not open, by hook (not shown) on plate B and plate C.By the cotter way 34 on the slotted eye on the plate C 30 and cantilever 6, the tailgate E be fixed on the cooperation of the pin rod 48 on the plate C, plate C can be moved to the left along the cotter way 34 of cantilever on the shelf 56 and tailgate E, till being close to shelf right side and back axle right side.Use as it being used as waggon, shown in 2, at first the clip on the High-foot hinge 4 24 is taken off, plate C and plate D temporarily take off from shelf 5.Then the car front and rear part is wrapped page or leaf 4 and rotate and to fold up, be fixed on the clip 16 on the crossbeam 14 of bicycle front fork 15 this moment, clamp the back fork of bicycle (not shown) by colliding its chuck 17.Like this, both prevented that the bicycle front and rear part from relatively rotating, prevented again that front-wheel 50 from swinging.Plate C and plate D are hung on the cantilever 6 of shelf 5 again, and will open fully on plate A and the plate D, the clip 18 on the plate A is clipped on the beam 20 at body frame rear portion 3, and the clip 19 on the plate D is clipped in (see figure 3) on the cant beam of body frame front portion 2.Left side pedal is down, and right pedal is last, and left leg is pedaled son and is through in the hole 36 on the plate A.Thereby formed a four-wheel go-cart.As the utility model being become interim desk or stool, as long as state shown in Figure 2 was fallen to the left, this moment,

pillar

37,39 and the pillar 38 on the plate A of plate B were supported on the ground (see figure 3) that the face of plate C and plate D just can be used as desktop or stool face.As the utility model is become bed, as shown in Figure 4.As long as plate C and plate D are taken off from shelf 5, and around pin rod 48 rotations, tailgate E rotates around pin rod 49, make plate A, B, C, D and E be in same plane, movable leg on plate A and the

plate D

7,8 is opened, adjust the height of

movable leg

7,8 and Convenient table 9,10, it all is supported on the ground, thereby formed jury bed.Become chaise longue as need, as long as movable leg 7 or movable leg 8 are continued to heighten, make plate D and plate C or plate A and plate B relatively face tilt get final product.
