Description of drawings

Describe the utility model with reference to the accompanying drawings in detail, each parts are not proportionally drawn among the figure, and only are schematically, wherein:

Fig. 1 is the scheme drawing that the embodiment of the utility model Rowboat bicycle is shown;

Fig. 2 is the enlarged view that of the present utility model time power apparatus is shown; And

Fig. 3 is the decomposition view that of the present utility model time power apparatus is shown.

The specific embodiment

Fig. 1 shows an embodiment of the utility model Rowboat bicycle.As shown in Figure 1, Rowboat bicycle of the present utility model comprises: support 1, be installed in the front-wheel 3 of support 1 front portion and be installed in the trailing wheel 4 at support 1 rear portion by front fork 2.The handle 5 that is used to control this Rowboat bicycle working direction is arranged on front fork 2 by handle struts 6, and wherein the lower end of handle struts 6 is fixed on the front fork 2, and its upper end is fixedly connected on handle 5.This handle struts 6 is an expansion link, and it can stretch under the effect of handle 5 and shrink.Similar with ordinary bicycle, Rowboat bicycle of the present utility model also can comprise brake gear and be installed on the vehicle seat of mid-stent upside, no longer give unnecessary details at this.

Return power apparatus 8 and can rotate back and forth to be arranged at this support 1 middle part.Perhaps, can be provided with bracing frame 7 on this support 1, this time power apparatus 8 also can rotate back and forth to be arranged on this bracing frame 1.The rotation of this time power apparatus 8 activates by actuation cord 9, and wherein these actuation cord 9 parts are coiled on this time power apparatus 8, and the one end is fixed on back on the power apparatus 8, and the other end is fixed on the handle 5.For fear of actuation cord 9 and miscellaneous part mutual interference mutually, can make actuation cord 9 via one or more positioning elements 10 that are fixed on the support 1, for example, pulley is connected with handle 5.

Fig. 2 and Fig. 3 show the example that the utility model returns power apparatus.This time power apparatus 8 comprises: pivot shaft 18, and it is fixed on support 1 or the bracing frame 7; Wheel hub 19, it rotatably is arranged on this pivot shaft 18; And disc spring 20, for example, clockwork spring, it is set on the pivot shaft 18 in the centre hole of wheel hub 19, and its both ends are fixed in respectively on wheel hub and the pivot shaft.

First sprocket wheel 11 is fixedly set in back on the power apparatus 8, to rotate together in company with returning power apparatus 8.For example, as shown in Figure 3, first sprocket wheel, 11 bearings 21 can be by being arranged at back on the power apparatus 8, and wherein this bearing 21 is fixed in go back to wheel hub 19 ends of power apparatus 8.Perhaps, this first sprocket wheel 11 also can directly weld or by other connecting devices, for example rivet or screw, and be fixed in go back to wheel hub 19 ends of power apparatus 8.This first sprocket wheel 11 also is connected with first flywheel 13 that is arranged on trailing wheel 4 one sides by first messenger chain 12.Similar with the flywheel of ordinary bicycle, this first flywheel 13 is an one-way clutch, drives trailing wheel and rotates in one direction.

In use, the user is pull handle 5 up, thereby can draw back wheel hub 19 rotations of power apparatus 8 by this actuation cord 9.At this moment, wheel hub 19 will drive first sprocket wheel 11 and rotate synchronously, and this first sprocket wheel 11 drives 13 rotations of first flywheel by first messenger chain 12, and then drive trailing wheel 4 rotations of this Rowboat bicycle, and Rowboat bicycle is advanced.

When the user stops drag handle 5, wheel hub 19 contrarotation under the effect of disc spring 20, thus make the part of actuation cord 9 be coiled in the surface of wheel hub 19 again.And then 5 pairs of handle struts 6 of actuation cord 9 tow handle are pushed, and handle struts 6 is shunk.

Thereby the user of the utility model Rowboat bicycle can reduce the requirement of canoeing to the place on land according to the mode of rowing a boat by bike.

By returning first drive system that power apparatus 8, actuation cord 9, first sprocket wheel 11, first messenger chain 12 and first flywheel 13 form, Rowboat bicycle of the present utility model can also comprise second drive system except above-mentioned.This second drive system comprises: rotatably be arranged at second sprocket wheel 14 on the support 1, for example, be arranged on the middle part downside of this support 1; Relatively be arranged on second flywheel 15 of trailing wheel 4 opposite sides with first flywheel 13; And second messenger chain 16 that connects second sprocket wheel 14 and second flywheel 15.Similar with the flywheel of ordinary bicycle, this second flywheel 15 is an one-way clutch, drives trailing wheel and rotates in one direction.

Similar with ordinary bicycle, this second sprocket wheel 14 drives by pedal 17.The user can order about 14 rotations of second sprocket wheel by scrunching pedal 17, thereby drives 15 rotations of second flywheel by second messenger chain 16, and then drives trailing wheel 4 rotations of this Rowboat bicycle, and Rowboat bicycle is advanced.

By using first drive system, the user can drive this Rowboat bicycle according to the mode of canoe and advance; And by using second drive system, the user can drive this Rowboat bicycle according to the mode of riding ordinary bicycle and advance.The user can also be used alternatingly this two kinds of drive systems, and can not produce mutual interference.Thereby Rowboat bicycle of the present utility model can be tempered user's upper and lower extremities simultaneously, and has increased enjoyment by bike.

Although described the present invention with reference to preferred embodiment, the present invention is not limited to this, and those of ordinary skill in the art can carry out various improvement and distortion to the present invention under the premise without departing from the spirit and scope of the present invention.
