Abstract
The adjustable bicycle frame consists of six rods, rod 1 to rod 6. It features that rod 1 is hinged with one end of rod 2 and rod 6, rod 5 is hinged with the other end of rod 2 and rod 6, and rod 5 is adjustable in length. Adjusting the length of rod 5 can change the height of saddle and the distance between the front and the back wheels simultenously so as to make the bicycle suitable for people of different age and height.
Description
The present invention relates to a kind of bicycle rack that can regulate bicycle saddle height and front and back wheel distance simultaneously.
General bicycle rack is fixed, though the height scalable of saddle, front and back wheel is apart from not regulating.
The bicycle rack that the present invention introduced then is to regulate saddle height and front and back wheel distance simultaneously.
Principle of design of the present invention is: utilize bar (1), bar (2), bar (3), bar (4), bar (5), bar (6) to constitute main body of vehicle frame, its king-rod (1), bar (2), bar (5), bar (6) constitute a four-bar mechanism.Bar (3), bar (4), bar (5) constitute a triangle again, play fixation.Four bars (1), (2), (5), (6) are hinged in twos, bar in four bars (1) is an empty tube shape, for front fork is installed, and bar (3), bar (4) are forked at hinge-point e end respectively, for trailing wheel is installed, axis is installed on the hinge-point d or on the bar (4), saddle is installed in bar (5) from the extended end f point of d point to c point aspect.During use, the length of adjust bar (5), i.e. scalable saddle height and front and back wheel distance.When an end of bar (5) and hinge-point were thrown off, vehicle frame was collapsible.
Key problem in technology of the present invention is that the length of bar (5) is adjustable, utilizes the variation of bar (5) length to regulate saddle height and front and back wheel distance.
Advantage of the present invention is: by the length of adjust bar (5), can regulate saddle and front and back wheel distance simultaneously, the people that so just can adapt to all ages and classes, different heights uses, and has simple in structurely, and the characteristics that cost is low are suitable for each Bicycle Plant's upgrading products.
Introduce several embodiments of the invention below.
Embodiment 5 as shown in Figure 5, its difference from Example 1 is after bar (5) is nested together with two tubing, boring is with bolt (10) fixing and locking.
Fig. 1 constitutes bar (5) with bolt-nut assembly
Fig. 2 constitutes bar (5) with cylinder-piston component
Fig. 3 constitutes bar (5) with gear-tooth bar assembly
Fig. 4 locks with jackscrew
Fig. 5 locks with bolt
Claims (5)
1, a kind of adjustable bicycle rack, form by bar (1), bar (2), bar (3), bar (4), bar (5), bar (6), it is characterized in that: bar (1) is articulated in b, a point with bar (2), bar (6), bar (5) and bar (2), the other end of bar (6) is articulated in c, d point, the adjustable in length of bar (5).
2, by a kind of adjustable bicycle rack of claim 1, it is characterized in that: bar (5) is to be made of bolt-nut assembly.
3, by a kind of adjustable bicycle rack of claim 1, it is characterized in that: bar (5) is to be replaced by cylinder-piston component (7).
4, by a kind of adjustable bicycle rack of claim 1, it is characterized in that: bar (5) is to be replaced by gear-tooth bar assembly (8).
5, by a kind of adjustable bicycle rack of claim 1, it is characterized in that: bar (5) is after two tubing are nested together, and regulates fixing with jackscrew (9) locking or boring bolt (10).
