Detailed description of the invention

Below, for those skilled in the art in the invention can easily implement, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.But, describe in detail when the preferred embodiments of the present invention, be judged as while making main idea of the present invention indefinite for the detailed description of related known function or formation, can description is omitted.For the part with similar functions and effect, in whole drawing, use same or similar symbol.

And, in specification sheets, if mention certain part while " being connected " with another part, not only comprise " directly connecting ", also can comprise the situation of passing through other elements " connection indirectly " in the middle of it.While mentioning " comprising " a certain inscape, do not have in the situation of contrary record, do not represent and get rid of other inscapes, can also further comprise other inscapes.

Fig. 1 is the block diagram illustrating according to the bicycle pedal of the easy dismounting of one embodiment of the invention and raising propulsive effort.As described in Figure 1, according to the bicycle pedal 10 of the easy dismounting of one embodiment of the invention and raising propulsive effort, comprise: stretcher framework 200, latch for printed circuit 300, Lock Part 400.

Stretcher framework 200 is set to centered by stretcher axle 100 rotation, is conventionally formed as tetragonal state, as long as but can put bicycle user's pin, any form all can.But, for disperseing the pin applied pressure by bicycle user when, prevent that bicycle user's pin from departing from from stretcher framework 200, can form multiple friction projections 210 on the top of stretcher framework 200.

Latch for printed circuit 300 is formed on a side of stretcher framework 200.Existing bicycle pedal, only in the time that stretcher rotates downwards, the propulsive effort advancing is provided to bicycle, but the present invention uses latch for printed circuit 300, bicycle user's pin is fixed on stretcher framework 200, therefore, when bicycle user rotates bicycle pedal upward, also can provide the propulsive effort advancing to bicycle.Below, describe each formation of latch for printed circuit 300 in detail with reference to Fig. 2 and Fig. 3.

Fig. 2 and Fig. 3 are the figure illustrating according to the latch for printed circuit of the bicycle pedal of the easy dismounting of one embodiment of the invention and raising propulsive effort.As shown in Figures 2 and 3, according to the latch for printed circuit 300 of the bicycle pedal 10 of the easy dismounting of one embodiment of the invention and raising propulsive effort, comprise strut bar 310, stopper 320, limit rotation projection 330, elastomeric element (omitting diagram).

Strut bar 310 is arranged on a side of stretcher framework 200, so that parallel with stretcher axle 100.Stopper 320 preferably has cylindrical to can rotate, but is not restricted to cylindrical.Strut bar 310 use bolt combinations are arranged on stretcher framework 200, and in order not interfered in rotary course, possess the size low with the height of stretcher framework 200.

In the present invention, irrelevant with the stretcher framework 200 rotating centered by stretcher axle 100, strut bar 310 select and turns voluntarily, and therefore, bicycle user when directly going up direction and lift bicycle user's pin or shoes, easily separates shoes from latch for printed circuit 300.Specifically, when bicycle user lifts pin to straight upper direction, because the rear end (connecting the part of latch for printed circuit 300) of stretcher framework 200 is lifted, stretcher framework 200 rotates predetermined angular, another side, and stopper 320 rotates centered by strut bar 310, and hand of rotation is contrary with the hand of rotation of stretcher framework 200, therefore,, even if the tail end of stopper 320 has acute angle shape, also can easily isolate from stretcher bicycle user's pin.Existing chuck stretcher due at least front and back two directions or all around four directions upwards firmly fix shoes, be therefore difficult to separate.The present invention possesses the positive effect that existing chuck stretcher can not have.

Stopper 320, its one end is combined in strut bar 310, and axle rotates centered by strut bar 310, and the other end possesses bending shape to can hang in introduction hole 420.Bicycle user only if necessary, restrictively rotates stopper 320 and uses, while not driving bicycle, stopper 320 can be fixed on to the one side of stretcher framework 200, therefore,, when can preventing that stopper 320 from damaging, can also improve the comfort feature of keeping.

The other end of stopper 320 is formed as annular to can hang in the introduction hole 420 of Lock Part 400, if bending when annular, in order to firmly fix, angle of bend can be 20 to 90 degree.Bicycle user is by inserting stopper 320 to introduction hole 420, bicycle user's pin is fixed on stretcher, now, because bicycle user's pin is securely fixed on stretcher framework 200, therefore, even bicycle user rotating footrest upward, stretcher also moves together along with the movement of pin that bicycle uses, the propulsive effort that therefore can advance fully.

Limit rotation projection 330, in the time that stopper 320 rotates, the rotation of restriction stopper 320, so that stopper 320 is fixed on stretcher framework 200 with acute angle state.If stopper 320 is ad infinitum rotation centered by strut bar 310, bicycle user's pin is difficult to be fixed on stretcher framework 200.Therefore, the present invention forms limit rotation projection 330 at the tail end of stopper 320 so that limit rotation projection 330 limits the rotational angle of stopper 320, and then between the pin that prevents bicycle user and stretcher framework 200 in conjunction with unnecessary separating occurs.

Now, it is while tilting for acute angle due to stopper 320 that limit rotation projection 330 is fixed as acute angle by stopper 320 with the angle of stretcher framework 200, bicycle user can be more easily by Lock Part 400 and latch for printed circuit 300 in conjunction with or separate from latch for printed circuit 300.

Elastomeric element (omitting diagram) is formed on strut bar 310, in the time removing pressure, makes the stopper 320 rotating by bicycle user applied pressure can return to original state.Although, limit the rotational angle of stopper 320 by limit rotation projection 330, if bicycle user applies strong pressure to stopper 320, just can cause stopper 320 and limit rotation projection 330 are out of shape or damage.Therefore, coil spring or the elastic body at the lower end of stopper 320 stickup quality of rubber materials are set in the inside of strut bar 310, use elastomeric element by this type of mode, in the time removing bicycle user to stopper 320 applied pressure, stopper 320 also can return to suitable position.

Lock Part 400, uses on bicycle user's pin, with latch for printed circuit 300 combinations, bicycle user's pin is fixed on stretcher framework 200.Describe Lock Part 400 in detail with reference to accompanying drawing 4 and Fig. 5.

Fig. 4 is the figure illustrating according to the Lock Part of the bicycle pedal of the easy dismounting of one embodiment of the invention and raising propulsive effort.As shown in Figure 4, according to the Lock Part 400 of the bicycle pedal 10 of the easy dismounting of one embodiment of the invention and raising propulsive effort, comprise plate 410, introduction hole 420, static line 430.

Plate 410 is configured in the bottom surface of bicycle user's pin, and possesses four jiaos of length and width degree dull and stereotyped forms or possess the dull and stereotyped form of stream line pattern rib, to can effectively be incorporated into sole.Especially, the amplitude of plate 410 can be less than the sunk part of common sole, so that bicycle user also imperceptible inconvenience while not driving bicycle.

The plate 410 of form, is that bicycle user's pin is fixed on to the inscape on stretcher framework 200, and is formed with introduction hole 420 in the one side of plate 410 as mentioned above, and side can be connected and fixed rope 430.For durability, plate 410 can be made by reinforced plastic or metal.

Introduction hole 420 is formed on the one side of plate 410, and is combined in latch for printed circuit 300.Now, introduction hole 420 is formed as running through the one side of plate 410, and medial surface tilts to fixedly secure with latch for printed circuit 300.As mentioned above, when the tail end of stopper 320 is formed as bending annular, angle of bend can be acute angle, and for the tail end form corresponding to stopper 320, preferred its medial surface of introduction hole 420 tilts, to can firmly fix.

Introduction hole 420 is hole shape, and the height in hole is when low, and latch for printed circuit 300 exposes on plate 410, the loss of increase latch for printed circuit 300 or not attractive in appearance, therefore, plate 410 is formed as the periphery projection of introduction hole 420, can make latch for printed circuit 300 not exert pressure to bicycle user's pin.

Static line 430, is connected to the side of plate 410 stationary bicycle user's pin.Because static line 430 is pin or the shoes that encase stationary bicycle user, therefore preferably made by the metal or the plastic cement that there is no flexibility.

Now, the bicycle user's that static line 430 will wrap shoes, can be according to bicycle user, its size is also different, therefore, static line 430, compared with forming as one with plate 410, preferably connects to can adjust static line 430 length with predetermined space form.For this reason, can form static line hole 411 in the two sides of plate 410, static line 430 is connected in static line hole 411, and utilize Velcro mode, magnet mode or clasp mode that bicycle user's pin is fixed on plate 410.

Static line 430 can arrange multiple, so that bicycle user's pin can fixedly secure on plate 410, but, preferably use 2 static lines 430, so that bicycle user can be from the easy separate lock limiting-members of bicycle user's pin.

Fig. 5 illustrates to be combined in the constitution diagram on shoes according to the Lock Part of the bicycle pedal of the easy dismounting of one embodiment of the invention and raising propulsive effort.As shown in Figure 5, when using according to the easy dismounting of one embodiment of the invention and improving the bicycle pedal 10 of propulsive effort, bicycle user is arranged on plate 410 after sole, uses the static line 430 of the two sides that are connected to plate 410 to fix plate 410 and shoes.Now, as mentioned above, by plate 410 being arranged on to the sunk part of bicycle user sole, can easier use the present invention, and according to the size of shoes, suitably adjust the length of static line 430, can easily use Lock Part 400.

Fig. 6 and Fig. 7 are illustrated according to the easy dismounting of one embodiment of the invention and improve the bicycle pedal of propulsive effort in conjunction with the constitution diagram of shoes.As shown in FIG. 6 and 7, bicycle user is in order to be fixed on bicycle user's pin according to the easy dismounting of one embodiment of the invention and to improve on the bicycle pedal 10 of propulsive effort, first Lock Part 400 is combined on shoes, and stopper 320 is inserted into the introduction hole 420 of exposing at sole, thereby bicycle user's pin can be fixed on stretcher framework 200.

Conventionally, when bicycle user exerts pressure to stretcher, bicycle user is naturally by front part, and the part of saving bit by bit the large bicycle user of portion body weight is placed on stretcher, instead of bicycle user's pin or the middle body of shoes.Existing chuck stretcher is that the front portion that chuck is fixedly attached to shoes assigns to use, if and while not driving bicycle, need come on foot with the shoes that adhere to chuck, therefore, due to chuck dispersive pressure in time, and inconvenience on foot, and impact between chuck and the ground of metal material, there is unnecessary noise and vibration.

But in the present invention, when the front part of shoes being placed on stretcher due to bicycle user, the plate 410 that is formed with introduction hole 420 is positioned to the sunk part of sole, therefore, even if bicycle user comes on foot with the state that utilizes static line 430 that plate is attached on shoes, also imperceptible foreign body sensation, and there is not noise, there is no inconvenient sensation completely.

When bicycle user isolates bicycle user's pin from stretcher framework 200, conventionally, bicycle user lifts pin along direction straight above stretcher, and this mode is different from the action of rotating footrest upward (action of lifting when pulling back).Bicycle user is the action difference of the health when separating pin from stretcher when rotating footrest upward, the present invention utilizes this point, when bicycle user lifts pin along straight upper direction, stretcher framework 200 and stopper 320 rotate to be mutually opposite sense, and stopper 320 is easily departed from from introduction hole 420.The present invention without as existing chuck stretcher adopt the special action of rotation pin neck etc., just easily in conjunction with and separate, while driving bicycle, when improving user's comfort feature, also can prevent shoes and the contingency that reason causes such as stretcher does not separate.

Fig. 8 is the figure illustrating rotating downwards according to the bicycle pedal of the easy dismounting of one embodiment of the invention and raising propulsive effort.As shown in Figure 8, by according to the easy dismounting of one embodiment of the invention and when improving the bicycle pedal 10 of propulsive effort and rotating downwards, the mode that bicycle user is identical with utilizing common bicycle pedal, apply the pressure of vertical direction to bicycle pedal, make bicycle pedal rotation, and then the propulsive effort advancing.But, if while utilizing common bicycle pedal, when bicycle pedal is rotated upward, the propulsive effort that can not advance, and make the bicycle pedal of opposition side rotate the propulsive effort advancing downwards, and therefore, inefficent property.

Fig. 9 is the figure illustrating rotating upward according to the bicycle pedal of the easy dismounting of one embodiment of the invention and raising propulsive effort.As shown in Figure 9, by according to the easy dismounting of one embodiment of the invention and when improving the bicycle pedal 10 of propulsive effort and rotating upward, when pulling back pin, bicycle user upwards lifts, now heel is positioned at the position higher than tiptoe, just very naturally occurs using the action of heel rotary bicycle stretcher.Now, bicycle user's pin is in being fixed on the state on stretcher framework 200 by Lock Part 400 and latch for printed circuit 300, the present invention is the propulsive effort that both sides bicycle pedal is all rotated to advance by 360 degree, therefore, not only improve the power of travelling of bicycle, also can improve significantly bicycle user's movement effects.

And, if when the propulsive effort that bicycle user rotates to advance by 360 degree, can upwards lift being fixed on when pin on stretcher pulls back, otherwise, while separating shoes from stretcher, pin is lifted along straight upper direction.Action while separation with stretcher during due to generation propulsive effort is completely different, therefore, even if Lock Part 400 and latch for printed circuit 300 are with the open combination of shape and state of predetermined portions, but the present invention, lift upward in the process of stretcher user, can prevent between Lock Part 400 and latch for printed circuit 300 in conjunction with unnecessary separating.

The present invention as mentioned above, can implement various deformation or application according to those skilled in the art, and technological thought scope of the present invention can specify according to claim scope.
