Description

Multi-functional recumbent bicycle

The utility model relates to a kind of recumbent bicycle, is mainly used in workplaces such as motor vehicle repair.

Often to get under the automobile when repairing automobile, at this moment use the recumbent bicycle will be conveniently many.But it is but not too convenient to carry so long recumbent bicycle, and therefore the work that can be seated of requirement sometimes need a kind of multi-functional recumbent bicycle of design.

The purpose of this utility model provides a kind of multi-functional recumbent bicycle, and it can be lain and can sit, and the time spent can also not folded up.

Technical solutions of the utility model are as follows: multi-functional recumbent bicycle partly is made up of vehicle frame, movable castor, service creeper, bolster etc., and its vehicle frame is made up of left and right two parts, and hinge is housed between the left and right vehicle frame; Flexibly connect by forward and backward two groups of connecting rods between its bolster and the vehicle frame.The length of front rod equals the distance between the tie point of forward and backward two groups of connecting rods and vehicle frame.Back link and vehicle frame link have one section bending, the distance when it highly equals folding gathering the between forward and backward two groups of connecting rods.

Owing to adopt technique scheme, make that the hinge of recumbent bicycle between can left and right vehicle frame is the center, to folding up, it is less to take up space like this with left and right two parts, carries just to make things convenient for manyly.The bolster of this recumbent bicycle can overturn, and by the linkage between bolster and the vehicle frame bolster is upwards propped, and like this, as cushion, recumbent bicycle has originally just become seat coach with bolster, makes a car can do use more.The utility model modern design, compact conformation, convenient and practical.

Be described in further detail below in conjunction with drawings and Examples.

In the illustrated embodiment, multi-functional recumbent bicycle is made up of vehicle frame, movable castor (10), service creeper, bolster parts such as (1), wherein vehicle frame is made up of left frame (5) and right frame (6) two parts, service creeper is made up of long slab (4) and short slab (2), hinge (3) is housed between the left and right vehicle frame, can hinge be the center, with left and right vehicle frame to folding up.Folding back recumbent bicycle as shown in Figure 3.Be positioned at the upper left quarter of Fig. 3 after pillow-cushion part lease making wherein is folding, pillow faces down.For clarity sake, Fig. 4 has only got the part among Fig. 3, i.e. bolster part.From Fig. 4 to Fig. 7 four width of cloth figure, can comparatively be clear that the annexation between bolster and the vehicle frame.Flexibly connect by forward and backward two groups of connecting rods between this recumbent bicycle bolster (1) and the right vehicle frame (6).The length of front rod (8) equals the distance (op) between the tie point of forward and backward two groups of connecting rods and vehicle frame; Back link (9) has one section bending with the vehicle frame link, the distance (h) when it highly equals folding gathering the between forward and backward two groups of connecting rods.Like this, bolster (1) can back link and the tie point (o) of vehicle frame be fulcrum, to the upset of the vehicle body outside, be parastate to bolster and vehicle frame after, by the linkage between bolster and the vehicle frame bolster is upwards propped again.Fig. 4 to Fig. 7 has represented the process that the bolster upset is propped by linkage then successively.After bolster is propped, recumbent bicycle as shown in Figure 8, as cushion, recumbent bicycle has originally just become seat coach with bolster (1).Below, draw the feature that the process that becomes bolster is analyzed forward and backward two groups of connecting rods in from cushion (1) again.For making the bench upset freely, distance (op) before and after the length of getting front rod (8) equals between the tie point of two groups of connecting rods and vehicle frame, when bolster overturn like this, the two groups of connecting rods in front and back just can be that fulcrum keeps coaxial rotation with the tie point (o) of back link and vehicle frame, as Fig. 6, shown in Figure 5.Back link (9) has one section bending with the vehicle frame link, the distance (h) when it highly equals folding gathering the between the two groups of connecting rods in front and back, thus make smooth the putting in place in bolster upset back, as shown in Figure 4.

The two groups of connecting rods in front and back that connect bolster and vehicle frame as can see from Figure 9 in the present embodiment respectively have two; can with wherein certain the group connecting rod be combined into one; this type of simple transformation; because of it meets the described connecting rod connection features of this patent; its purpose all is identical with role, so still belong to the scope of this patent protection.

Regulate the length of back link (9), can guarantee that the bench position is smooth.In addition, also can be connected by the fixed rod seat (13) of different length between the two groups of connecting rods in front and back and the bolster (1), regulate pole socket length, can further guarantee between bolster and vehicle frame upset freely, it is smooth to put in place.

After cushion was propped, the angle of connecting rod upset was spent greater than 270, and leans on crosspiece (12) thereafter, can make cushion stable.For fixing cushion and prevent that it from dumping forward, present embodiment also is provided with the safety fastener (11) that is used for fixing front rod (8) on vehicle frame.The position of safety fastener as shown in figure 10.Need unclamp safety fastener, cushion could overturn.

Convenient when the multi-functional recumbent bicycle of the utility model is used, present embodiment also below vehicle frame headrest pad one side be provided with instrument cases (7).As shown in Figure 8, when becoming seat coach, instrument cases are positioned at by cushion (1) side, and the instrument of taking like this is very convenient.

The multi-functional recumbent bicycle of the utility model can be used for multiple workplace, also comprises all reasonable purposes such as leisure, outing.
