The specific embodiment
Below, with reference to structure, lock operation and the action effect of description of drawings bicycle crank arm apparatus for adjusting position of the present invention.
Fig. 1 is the erection plan of the crank position control apparatus of bicycle of the present invention, Fig. 2 is the dismounting figure of the crank position control apparatus of bicycle of the present invention, Fig. 3 is the exploded perspective view of the crank position control apparatus of bicycle of the present invention, the section drawing of Fig. 4 presentation graphs 1.
As shown in the figure, the crank position control apparatus of bicycle of the present invention comprises: the holding element of cranking arm (Stay Crank Arm) 11, be inserted into bent axle 10b and with bent axle 10b one rotation, described bent axle 10b is inserted in the bicycle frame 10a; (the Crank Arm) 12 that crank arm, combine with holding element 11 hinges of cranking arm and with crank arm holding element 11 coaxial rotatablely moving; Spring clip (Spring Clip) 13 prevents to crank arm 12 from holding element 11 disengagings of cranking arm; And blocking device 14, will crank arm and 12 be fixed in the holding element 11 of cranking arm.
Upper side one end of holding element 11 of cranking arm combines with accelerator that is inserted with ball-bearing casing 10e or change-speed box 10c, and upper side one end 12 combines with cranking arm, and the upper side other end combines with bent axle 10b.
Be formed with four jiaos of holes 15 that gripped by bent axle 10b in the inboard of the holding element 11 of cranking arm, be formed with a plurality of position adjustments hole 16 of the stop pin 14a that is used to insert blocking device 14 in the outside, these a plurality of position adjustments holes 16 are media of regulating 12 the position of cranking arm.
12 the side of cranking arm be formed with in conjunction with the time be positioned at connect apertures 17 on the same angle with the position adjustments hole 16 of the holding element 11 of cranking arm, assembling blocking device 14 is formed with and the hinged pedal hinge of pedal (not shown) connecting bore 18 at opposite side in this connect apertures 17.
External diameter one side at 11 holding elements of cranking arm along the circumferential direction is formed with groove 19, inserts spring clip 13 in this groove 19, thereby can prevent to crank arm 12 disengaging.
A position adjustments hole 16 in a plurality of position adjustments hole of the holding element 11 of will cranking arm by blocking device 14, with 12 the connect apertures 17 of cranking arm in the stop pin of blocking device 14 of assembling when linking, decision 12 the relative positions of another crank arm (not shown) in cranking arm with respect to two of bicycle of cranking arm.
That is, when using bicycle, crank arm for two and use in the mode at mutual formation 180 degree angles, when folding, by with the position adjustments hole 16 of blocking device 14 bindings and the lock adjustment of connect apertures 17, can make to be positioned on the equal angular.
Fig. 5 is that the part of blocking device of the crank position control apparatus of bicycle of the present invention is cut block diagram, the A-A section drawing of Fig. 6 probability ground expression Fig. 1 when the blocking device of use Fig. 5.
As shown in the figure, blocking device 14 comprises stop pin 14a, housing 20, spring 23 and block 24.
Stop pin 14a is by the upper board 21 and lower panel 22 resilient mountings of housing 20, if be pulled upwardly stop pin 14a, then stop pin 14a rises and removes locked body, if unclamp the stop pin 14a of pull-up, then stop pin 14a elasticity under the effect of spring 23 falls, thereby locks locked body.The auxiliary device that carry out lock function this moment is a block 24, and block 24 cards end on the lower panel 22 of housing 20, flexibly carry out the lock function of locked body.
With reference to Fig. 6, A represents that the front end of stop pin 14a does not have the situation of tapering (taper), and B represents that the front end of stop pin 14a has the situation in tapering, either way the constitution diagram of the locked body of expression locking (crank arm holding element 11 and crank arm 12).
Under the situation of A, if 12 be fixed under the state of the holding element 11 of cranking arm and produce play cranking arm, then can expect and to rock, rock in order to remedy this, form the tapering and illustrate, 12 to be fixed on the example that makes the abnormal sound minimum that produces by play under the state of the holding element 11 of cranking arm cranking arm at the end of stop pin 14a.
Fig. 7 is the block diagram of double locking stop pin of the crank position control apparatus of bicycle of the present invention, and Fig. 8 is the A-A section drawing of the Fig. 1 when roughly representing to use the blocking device of Fig. 7.
(7a-1) of Fig. 7 is the block diagram of double locking device, (7a-2) is the block diagram of housing, (7a-3) is the block diagram of stop pin.
A ' the expression of Fig. 8 is based on 1 grade of lock-out state figure of stop pin 14a, and B ' expression is based on 2 grades of lock-out state figure of block.
As shown in the figure, the double locking device comprises stop pin 14a, housing 20, spring 23, block 24 and locking plate 25.
Internal run-through to housing 20 inserts stop pin 14a, is formed with knob in the upper end of stop pin 14a, in the outside of the in-to-in stop pin 14a that is positioned at housing 20, is provided with spring 23 with the state of reeling.
Be formed with block 24 in the bottom of stop pin 14a, this block 24 connects with the lower panel 22 of housing 20 under the elastic force effect of spring 23, and stop pin 14a is up-and-down movement under the elastic force effect of spring 23, thereby block 24 carries out 1 grade of locking and removes.
Operating process to the double locking of such formation describes as follows.
In the hole 16 of holding element 11 of cranking arm, insert the front end of stop pin 14a if be pulled upwardly stop pin 14a, then stop pin 14a is subjected to downward power under the elastic force effect of spring 23, finishes crank arm holding element 11 and 12 the 1 grade of lock out action (with reference to the A ' of Fig. 8) of cranking arm.
Secondly, if making stop pin 14a is the angle (serving as to close closed region among Fig. 7) of benchmark rotation regulation with the center shaft of stop pin 14a, then block 24 is between lower panel 22 and locking plate 25, thereby even if finishes along the direction of principal axis pull-up stop pin 14a of the stop pin 14a that unlocks, 2 grades of lock out action (with reference to the B ' of figure 8) that lock-out state also can not be disengaged.
The releasing of locking is undertaken by the inverted order of above-mentioned lock out action, earlier removes 2 grades of lockings (to the partial rotation of opening of stop pin 14a) afterwards, pull-up stop pin 14a vertically, thus remove 1 grade of locking, finally finish to remove and move.
More than, with reference to description of drawings preferred embodiment of the present invention, but be appreciated that those of ordinary skills under the situation that does not change technological thought of the present invention or essential feature, can implement the present invention in other concrete modes.Therefore, embodiment that is interpreted as above record etc. is exemplary, rather than it is determinate, scope of the present invention is not to limit by above-mentioned detailed description, but embody by the scope of claims described later, therefore should be interpreted as the implication of Accessory Right claimed range and scope with and equivalents all changes of deriving or the mode of distortion include in scope of the present invention.
