Referring to accompanying drawing,, showed the cycle rack 10 on a kind of vehicle frame 12 that is fastened at bicycle 14 among the figure especially referring to accompanying drawing 1-3.Though shown support 10 is fixed to having on the vehicle frame member of support relation with bicycle rear of extending back, concerning those skilled in the art, clearly, also can take support is fixed on other the position that cooperation relation is arranged with bicycle.

Support 10 comprises that one is roughly columniform overcoat 20, and described overcoat is made up of the member 22 that matches, and member 22 is fixing with fastener 24 with the mutual operation relation.Overcoat can be made by metal, adopts the moulding of synthetic plastics injection-mould casting, perhaps also can consider to adopt known method commonly used and material when making such overcoat.

Overcoat 20 match semimember 22 is determined cylindrical cavities 25 shown in Figure 2, to be described in detail below by the guide 26 that semimember 22 is provided that matches, should be noted that the vertical direction microscler crack groove 28 at angle of guide 26 definite relative proper motion cars 12.In the perisporium of overcoat 20, also dispose inlet slot 32, be equipped with in the groove 32 and be used to drive the pallet that is positioned at overcoat or the actuator 34 of lock 36.

Be anchored on overcoat 20 periphery and radially with crack groove 29 and determine the guide 26 of crack groove 28 opposed be fastening clamp 38.Described clamp 38 is made up of double part 42 of the symmetry that is roughly semi-circular shape, and its size makes it can be around the tubulose vehicle frame member of bicycle 14, and by screw/nut assembly 44 double part 42 is kept exercisable relation with the tubulose vehicle frame member.Overcoat 20 crank shafts general and bicycle are provided with at interval.As there not being the interval, then clamp can move on vehicle frame 12 backward.

Torsion spring 48 is reeled and also is connected on the jack-post 46 that constitutes fastener 24 cylinders, torsion spring 48 is secured to microscler, telescopic arm mechanism 50.Propping up arm mechanism 50 can be by the material of number of different types, as making such as spring steel, synthetic plasticss.Find out that by clear among Fig. 5 scalable support arm spare 50 has arc section, the rigidity when attempting to increase support arm spare and being in extended position, it still can retract to the state of coiling shown in Fig. 2 simultaneously.Crack groove 28 in guide 26 forms has corresponding arc section.
