Abstract

The utility model provides a leisure pedal tricycle. A rider can adjust relative positions of a backrest, a chair and pedals to make double legs obtain an optimum pedaling distance and can adjust the length and the height of a handle bar to make both hands obtain an optimum distance for holding the handle bar. Thus, people of different statures feel very comfortable in riding. A steering structure in a four-connection rod form makes turning operation flexible. The leisure pedal tricycle is especially suitable for outgoing persons at middle and old ages to replace walking.

Description

The leisure type trishaw of riding comfortable

Technical fieldThe utility model relates to trishaw, is a kind of leisure type trishaw that has the backrest seat specifically.

Background technologyThe leisure type trishaw pattern that has the backrest seat is a lot, but common weak point is arranged, though first seat can fore-and-aft adjustment, but different because of bicyclist's stature, thereby can not take into account simultaneously both legs trample distance and both hands hold up the distance of holding handlebar all to be in optimum regime, can feel uncomfortable when riding, it two is that distance between seat and the handlebar is bigger, and steering operation is not nimble.

Summary of the inventionThe utility model provides and a kind of the people of different statures can both comfortablely be ridden, and the very nimble leisure type trishaw of steering operation.

Description of drawingsFig. 1 is the complete vehicle structure scheme drawing (side-looking) of embodiment, numbers among the figure: steering shaft before steering shaft behind the vertical tube part of 1--1 backrest seat, 1--2 handlebar, 1--3 handlebar sleeve, 1--4 rear profile tube, the 1--5, the 1--6 (fork shaft promptly), the preceding standpipe of 1--7,1--8 front fork shoulder or before turn to cross bar after turning to cross bar, 1--9 front fork, 1--10 steering track rod, 1--11.(turning to the not marked circle in pull bar two ends among Fig. 1 is hinge point) Fig. 2 is the scheme drawing (overlooking) that turns to part-structure among Fig. 1, numbers among the figure: the vertical tube part of the transverse tube of 2--1 handlebar part, 2--2 handlebar, 2--3 rear profile tube, 2--4 left steering pull bar, 2--5 front fork shoulder or the preceding grip that turns to cross bar, 2--11 handlebar sleeve, 2--12 handlebar behind steering shaft behind steering shaft (promptly preceding fork shaft) before standpipe before cross bar, the 2--6, the 2--7,2--8 right steering pull bar, the 2--9, the 2--10 that turns to.(turning to the not marked circle in pull bar two ends among Fig. 2 is hinge point) Fig. 3 is handlebar length and highly adjustable structural representation (side-looking), numbers among the figure: steering shaft, 3--6 handlebar sleeve and back steering shaft hinge point, 3--7 trimming screw support behind the fixing screw of 3--1 handlebar vertical tube part, 3--2 handlebar sleeve, 3--3 adjustment handlebar height, 3--4 rear profile tube, the 3--5.Fig. 4 changes the scheme drawing (overlooking) become chain, sprocket wheel steering structure with four connecting rod steering structures, numbers among the figure: steering shaft, 4--2 turn to sprocket wheel before turning to and turning to sprocket wheel, 4--7 after the vertical tube part, 4--5 handlebar sleeve, 4--6 of steering shaft (promptly preceding fork shaft) before chain, the 4--3,4--4 handlebar behind the 4--1.

The specific embodimentAs shown in Figure 1: a seat (1--1) that can move forward and backward and have backrest is set at the vehicle frame rear portion, and the bicyclist adjusts the relative position of backrest seat and pedal according to the needs of oneself, can make both legs obtain the best distance of trampling.Front portion and preceding standpipe (1--7) at vehicle frame are provided with a rear profile tube (1--4) accordingly, back steering shaft (1--5) bottom in rear profile tube turns to cross bar (1--11) after connecting one, turns to cross bar (1--8) before preceding steering shaft (1--6) bottom connects one.As shown in Figure 2: after turn to the two ends of cross bar (2--10) and the two ends that before turn to cross bar (2--5), hinged with steering track rod (2--4 and 2--8) by attaching parts, formed the steering structure of one four connecting rod form.When handlebar drives the back steering shaft and rotates, after turn to cross bar, steering track rod, preceding cross bar, preceding steering shaft and the front vehicle wheel of turning to link simultaneously, thereby realize turning to of car load.

In the steering structure of this four connecting rods form:

A, can be with the forward and backward top that turns to cross bar to be arranged on forward and backward steering shaft;

B, the steering track rod of rigidity can be changed into flexible drag-line;

C, turn to cross bar before can not being provided with, but steering track rod (2--4 and 2--8) is hinged by the two ends of attaching parts and front fork shoulder (2--5); More than the turning efficiency of these three kinds of versions, all be identical with aforesaid four-bar linkage structure form.As shown in Figure 4: in four connecting rod steering structures, turn to chain (4--2) as if steering track rod is varied to, will turn to cross bar to be varied to and turn to sprocket wheel (4--6 and 4--7), this version also is identical with the turning efficiency of four-bar linkage structure.As shown in Figure 3: handlebar vertical tube part (3--1) is inserted in the handlebar sleeve (3--2), and the degree of depth of plug-in mounting can be adjusted, thereby realizes the variation of handlebar length.Handlebar sleeve (3--2) is hinged with back steering shaft (3--5) upper end, and the angle between the two can pass through fixing screw (3--3) to be determined, thereby realizes the variation of handlebar height.The bicyclist is according to the needs of oneself, to handlebar length and highly adjust, can make both hands obtain to hold up the optimum distance of holding handlebar.

The version of brake system can be selected from prior art, does not do detailed description at this.

Good effect of the present utility model is:

1, the bicyclist of different statures can be according to the needs of oneself, adjust the relative position of backrest seat and pedal, make both legs obtain the best distance of trampling, adjust the length and the height of handlebar, make both hands obtain to hold up the optimum distance of holding handlebar, thereby can ride the most comfortable;

2, because the handlebar sleeve is and back steering shaft pivotally attached, so handlebar upwards can be dug, so just strengthened the space between seat and the handlebar, make when getting on or off the bus very convenient;

3, four connecting rod steering structures, (or chain, sprocket wheel steering structure) can make handling maneuver very nimble.
