The bicycle, leisure that the invention provides bicycle that a foldable bicycle and a support body assembly make this bicycle can have different patterns such as urban district to use, mountain-climbing usefulness with bicycle, children with bicycle and contest bicycle.

A complete stack-mounted bicycle be must understand and wheel body, pedestal, pedal and driver train comprised as driving axle and actuator, and the folding handle that is installed to this support body, but also essential understand bicycle also can be in part stack-mounted form, comprise this support body at least and other assembly can be installed on this support body subsequently.

The explanation bicycle is folding in the literary composition.Be, generally it has two kinds of kenels, promptly uses kenel, and the user can drive this bicycle in this kenel, and a folded configuration, and wherein this bicycle is folded and thinks that the user is entrained, and perhaps the user can rotate it or be stored.Obvious folding kenel from explanation hereinafter comprises a complete folded configuration, and both all associated components are folded fully to be beneficial to and are used for storing, and comprise one group of folded configuration, and wherein this hold-down arm and back handle projection come out to rotate with auxiliary wheel body.

So-called support body assembly refers to be used for the basic framework of folding cycle in the literary composition, does not wherein comprise to be used for the front-wheel hold-down arm, the hold-down arm of for example two forks or single tine kenel.So-called support body and preceding paragraph wheel body installation component mean the combination of support body assembly and front-wheel hold-down arm in the literary composition.Wheel, pedal, pedestal, handgrip and other sub-assembly system are installed in these assemblies by the method for generally knowing.

The after-frame position comprises the installing mechanism that is used for trailing wheel.Preferably both comprised the installing mechanism that is used for pedal, one drives axle, the moving device of axle and a pedestal.This general plane, general Anyi, trailing wheel position on spatial relationship.Preferably this trailing wheel rotates on the plane of back and coplane on this group of plane in use.

This front frame body position is attached to this back frame body position with pivot makes both to fold mutually.Preferably this front frame body position and this back frame body position fold when making folded configuration needed space and reach minimum.The present invention comprises relation adjacent and coupling on some viewpoint.The general front frame body of essential understanding position is by the defined plane of support body in using kenel.

This pin connected assembly is attached to this side arm position with the pin refining.As refining via hank.Dispose this pin connected assembly and as rotating the hold-down arm that the wing includes the installing mechanism that is used for front-wheel is installed in the mode that utilization can articulate.

The strand at frame position and after-frame position refining formula or link and link to the strand refining of the pin connected assembly at side arm position before the above-mentioned explanation, on the general system utilization structure for single strand refining as can bear distortion and crooked strand is refined and reached its purpose.On some viewpoint, its mode becomes for the strand refining of using wide interval is tall and erect or feature fastened to each other is carried out combination on defined strand refining position, as locating in the use location.

The first strand refining position of the strand refining of this strand of definition refining bindings provides an outstanding position on some viewpoint, provides a cavity such as female position to receive to be somebody's turn to do when the strand refining sealing as public position and the second strand refining company headquarters position and gives prominence to the position.Its form of outstanding position at best first position is that the cavity at a wedge shape and second position has corresponding shape.The surface of preferably giving prominence to the last cavity in position is coated on one deck Buddhist nun and hinders material such as nylon, but makes Buddhist nun's resistance twist any mobile as vibrations of refining place in sealing.

Linking on system is articulated in by defined plane, side arm position in the strand between side arm position and this pin connected assembly refining on some viewpoint.

But linking in the refining of the strand between side arm position and this pin connected assembly on some viewpoint is to be articulated in another place, plane that departs from mutually on the plane at this side arm position.Therefore generally, the angle that departs from is spent to 25 degree as 22 degree from 0.1, and the strand refining plane of moving departs from that to be differed by this defined plane, side arm position be 0.1 to 25 degree, as 22 degree.This out-of-position design department determines to have preferable parallel fitting relation in the folded configuration of whole wheel at bicycle aiding in.

Hold-down arm comprises an installing mechanism that is used for side arm.Preferably this hold-down arm also comprises an installing mechanism that can be used for handgrip, both can have cooresponding suitable kenel.Essential understand in using kenel, by the defined pivot of this pin connected assembly position on by defined plane, after-frame position.

Carry out moving forward or backward on the strand refining formula that corresponds to the pin connected assembly at side arm position when bicycle is folding moves and moves this bicycle for example with relative position, preferably make when a hold-down arm is pivotally attached to it at the side arm position and the distance of front-wheel installing mechanism will thereby increase.This reads for considerable pass among the present invention, and this is because do not have this to move and action front-wheel installing mechanism does not at interval have enough spaces to allow carrying out best location in folded configuration.

Preferably should as forward or outside move enough distance such as the spaces of generation between this front-wheel installing mechanism and side arm position, make the mutual each other jackknife action in side arm position and after-frame position will cause front-wheel and trailing wheel installing mechanism to enter more suitable fitting relation each other.This expression reaches best folded configuration, and this is because the installing mechanism of wheel and therefore be installed to the configuration mode that wheel itself on it reaches the side opposite side.The identical commentaries on classics of taking turns for this folding cycle can use of an advantage of the best kenel of this kind, each rotates frenulum and the wheel shaft of identical turning cylinder as alignment.Basically, side is being pacified two wheels its effect as single wheel body of side.The advantage of this function is inequality based on the wheel folding cycle of other complete size, and this front-wheel does not need to get rid of with folding this bicycle.

Be coupled this after-frame position and pin connected assembly makes that move the mutual folding position of this side arm position and this front-wheel installing mechanism that causes between this side arm position and the after-frame position, and preferably stretching mutually each other just increases at interval, the mode of reaching this coupling is suitable coupling mechanism, wherein comprises to have one or more by being the coupling arm of simple form formula.

The coupling mechanism of above-mentioned explanation can import the folding and action at interval of support body, therefore reduces step and complexity required when using kenel to become folded configuration, otherwise easily right.When another viewpoint be taken in to import jackknife action, the action of this coupling was extrapolated and move around this support body assembly with the front-wheel installing mechanism, also therefore avoided in this support body N/R action, especially pedal and back crank-driven device between any sub-assembly.

Preferably the action at interval of this extension back is that put the right position of above-mentioned explanation, and wherein folding fully action causes front-wheel and trailing wheel installing mechanism to enter adaptive position to each other.

According to another viewpoint of the present invention, the invention provides framework and this bicycle of front component that is used for folding cycle and comprise;

This position, one after-frame position comprises an installing mechanism that is used for trailing wheel;

One side arm position links this after-frame position with the strand refining and makes two positions to fold mutually;

The pin connected assembly that is used for a hold-down arm is attached to this side arm position with the strand refining;

And a hold-down arm that is attached to this pin connected assembly, it comprises an installing mechanism that is used for front-wheel.

Wherein this trailing wheel position and pin connected assembly are coupled and make when this side arm position and after-frame position fold, this pin connected assembly can be done pivot and moves relative to removing the side arm position, and one shift to this hold-down arm, therefore increases the interval between this side arm position and this front-wheel installing mechanism; And

One lock wherein is provided, had both twisted in the refining osed top state this lock in running condition and can oppositely pin this and before and after take turns the position, and this lock comprises one and can adjust the fixed arm that articulates in the installing mechanism.

Preferably this fixed arm comprises a centrifugal installing mechanism.

When folding, the strand refining formula of pin connected assembly that should the side arm position moved and to move this hold-down arm and make this front-wheel installing mechanism moving by the side arm assembly.Be coupled the feasible folding each other support body position of this back frame component and this pin connected assembly with the distance elongation between side arm position and front-wheel installing mechanism.

Basically this support body and front-wheel installing mechanism assembly comprise above the support body assembly of explanation and are used for the hold-down arm of front-wheel.

According to another viewpoint of the present invention, the invention provides a wide frame component and can be used for the folding bicycle, wherein comprise an after-frame position and make the after-frame position that one installing mechanism that is used for trailing wheel be arranged; It is attached to one side arm position this after-frame position with strand refining and makes two positions to fold mutually; Before machine proficiency can oppositely be pinned on strand refining osed top position and is somebody's turn to do and this back and side arm position, wherein this handbag contains one at the fixed arm that can adjust in the installing mechanism.

Can operate this fixed system easily, wherein this fixed system uses that fixed arm used adjust drive the meter installing mechanism, its assembly is less cooresponding and structure is very strong and in light weight.Basically the adjustable arm that installs and fixes can be situated between this coupling bar and the after-frame position in the embodiments of the invention.Adjustable pin connected assembly is provided via install and fix arm in centrifugal installing mechanism, therefore can changes the tension force of coupling bar.The centrifugal installation component that use has fixed arm can provide the pin-joint mechanism adjusted with high mechanical advantage.Also can use other adjustable installing mechanism on the other hand among the present invention, as lever, gear, hydraulic efficiency pressure system with high mechanical advantage.

Centrifugal installing mechanism with fixed arm provides the mechanical advantage of height, thus can increase the tension force of coupling bar, and two strand refinings of sealing tightly.When this centrifugal installing mechanism of counter-rotation, can reduce tension force and make that can untie this strand when folding this bicycle easily refines.So do not need the spring of above-mentioned explanation to open up mutually or length-adjustable coupling bar, the center-point of essential extend through strand refining when this contact launches fully.

When bicycle when driving pattern, dispose be attached to this centrifugal mechanism fixed arm to be attached to this pin connected assembly, preferably this moment this coupling bar at open state.Ideally the binding between this fixed arm and this pin connected assembly can so that this fixed arm at the state of upholding and can be fixed on this pin connected assembly.The quick detach lever that system uses a standard is the same or use the mechanical link device of other appropriate form as the bicycle hub that is used to link and launch, as has the device or the anchor fitting of screw thread.The whole length of this coupling bar and coupling arm is adjustable, and for example the end points for these provides screw thread, but and provides the automatic key of the resilience that can adjust or can replace to make the assembly that can add other in this system for the contact of strand refining.

When bicycle when driving pattern, via the coupling bar and the fixed arm that use simultaneously under the stretched condition, can be so that this support body be kept cooresponding rigidity and strong structure in crooked or distortion.Its advantage is for having very effective structure and this is a bicycle characteristic basically.

Preferably locate this fixed arm and make the distance between this fixed arm and the strand refining axle be maximum, for example the position is in the inboard of the support body bar that is attached to coupling.Therefore one refine at closed state, and keep the rigidity of this bicycle support body when being attached to pin connected assembly and having during at stretched condition the momentum of a maximum can keep this strand.Main strand refining between side arm component and after-frame component as vertical strand refining can be so that the curved districts of its nadir and depart from the open-shelf body therefore in the outside of coupling bar and fixation wall.This makes these reach maximum by the sealing strength that tension force produced in linking during in folding pattern when bicycle, and maintains strand refining near the top of rider's support body at the state that compacts most.

The position of coupling bar and installation be can adjust during in folding pattern via rotational fixation arm and centrifugal installing mechanism when bicycle, the before and after fit of wheel and the degree of registration of axle therefore adjusted.This action also forms the Ji Chu of a fixed system between wheel body, therefore before and after the wheel hub beans lock mutually or similarly link together, and is quiet to moving as carrying out each other.This can replace or append on the wheel fixed mechanism of above-mentioned explanation.
