Description

There is the folder for folding bicycle of double locking effect

Technical field

The present invention relates to a kind of folding bicycle folder, relate in particular to a kind of folder for folding bicycle with double locking effect.

Background technology

At present, the common folder that is equiped with between pipe fitting on folding bicycle, in order to operate the jackknife action between pipe fitting.Common folder is installed on main car frame between (in order to by vehicle frame folding), handlebar stem and front fork tube on (in order to handlebar stem is downwards folding) or seat bar (in order to seat cushion is downwards folding), and the position that its contexture and installing are used is more.The folder of installing on folding bicycle at present, is generally point to have left and right housing, and is worn and pivot joint by an axostylus axostyle in a side, makes can close up between the housing of left and right or does taking this axostylus axostyle as axle center and launch to move; Non-pivot joint side at left and right housing is provided with a quick detach group, this quick detach group can, in the time that left and right housing closes up, produce locking action to left and right housing, and left and right housing cannot be thrown off voluntarily easily, therefore must, via this quick detach group unlocked effect of operation, just left and right housing can be launched.The folder of installing on existing folding bicycle is distinguished the following two kinds of states that mainly contain in the use:

1. when the left and right housing of folder closes up, (no matter the locking of quick detach group or non-locking), does not do folding between two pipe fittings that folder is set up.

2. when the left and right housing of folder launches, quick detach group non-locking, and between two pipe fittings set up of folder, done folding.

The folder of installing on existing folding bicycle produces locking action via this quick detach group of operation with the left and right housing to folder in the time that left and right housing is closed up, and the locking action generally producing by quick detach group itself is called first and re-locks effect.Because general quick detach group all has a lever, produce locking action or unlocked effect with handled easily quick detach group, that is no matter be will produce locking action or want unlocked effect, capital operates this lever, therefore only have the folder of the first weight (substance) locking action in actual use, can exist this lever easily because being shaken or touched unintentionally (or hitting) and be offset the defect of (unlocked), especially the folding bicycle movement of advancing in the environment for use of regular vibrations, if therefore the suddenly skew of this lever and the locking of untiing folder in incognizance, probably will cause rider to produce serious disaster.

Therefore there is afterwards the folding bicycle folder of tool double locking effect to produce, it as shown in the first figure, is a kind of folding bicycle folder 1 of common tool double locking effect, it has a left shell 11 and a right shell body 12, engages respectively with first and second pipe fitting 111,121; Left and right housing 11,12 wears and pivot joint by an axostylus axostyle in a side, left and right housing 11,12 can be closed up or do taking this axostylus axostyle as axle center and launch action; Non-pivot joint side at left and right housing 11,12 is provided with a quick detach group 13, and its outside obviously has a lever 131, uses in order to the intraware variation that operates this quick detach group 13; In the time that left and right housing 11,12 closes up, can pull this lever 131 and close up to the second pipe fitting 121 directions, so that producing first to left and right housing 11,12, the intraware of this quick detach group 13 re-locks effect; Be installed with a card 14 in these the second pipe fitting 121 outsides in addition, uphold elastomeric material formation for having, opening part does recessed shape, when this lever 131 can touch this card 14 in the time that the second pipe fitting 121 directions are closed up, and inwardly clamp-ons to locate; Therefore by this card 14, grasping of lever 131 reached to second and re-lock effect.But its shortcoming is this card 14 and is not durable, using soon it to uphold elasticity is rapid drawdown, and causing second, to re-lock effect loose and show for not good.

As shown in the second figure, be the folding bicycle folder 2 of another kind of common tool double locking effect, there is equally a left shell 21 and a right shell body 22, engage with first and second pipe fitting 211,221 respectively; Left and right housing 21,22 wears and pivot joint by an axostylus axostyle in a side, left and right housing 21,22 can be closed up or do taking this axostylus axostyle as axle center and launch action; Non-pivot joint side at left and right housing 21,22 is provided with a quick detach group 23, and the variation that its outside operates these quick detach group 23 intrawares by a lever 231 is moved; In the time that left and right housing 21,22 closes up, pull this lever 231 and close up the intraware that can make this quick detach group 23 to the second pipe fitting 221 directions and left and right housing 21,22 is produced to first re-lock effect; In addition, on this lever 231, offer a jack 232, and contiguous these jack 232 places are equiped with one and can pull and locations 24 that can upper and lower deflection on this second pipe fitting 221, mainly that its bottom has a clipping block 241, therefore in the time that this lever 231 closes up completely to the second pipe fitting 221 directions, can pull this locations 24 to lever 231 direction deflections, as shown in the 3rd figure, this clipping block 241 be supported into this jack 232 and locate; Therefore by this clipping block 241, the clip of lever 231 is reached to second and re-lock effect.Its shortcoming is that this locations 24 is because being to be simply articulated on this second pipe fitting 221, therefore use procedure is easily loose due to regular vibrations, cause in the time that operation folding bicycle does jackknife action, must have on the other hand turning round and look at this locations 24 and do not fall, make to operate folding bicycle and do folding action and become very and have some setbacks.Moreover, in the time that this locations 24 is loose, also may occurs in the clipping block 241 because of this locations 24 in the process of driving and jump out of this jack 232, and make second to re-lock effect and remove suddenly, relatedly cause uncertain danger.

One second housing 32, and between this first housing 31 at homonymy place by pivot 323 pivot joints, in the middle of the non-pivot joint side of this second housing 32, there is one second breach 321, this the second gap opened place laterally implant one and second housing 32 affixed second wear axle 322, separately, in the outside of this second housing 32 be affixed one second pipe fitting 324 (shown in accompanying drawing 10);

One lever 33, is sheathed on described second by a joint block 331 and wears on axle 322; Contiguous the second housing 32 places of lever 33 are horizontally arranged with a clamping cylinder 332 cylindraceous, then, as shown in Figure 9, this lever 33 offers a containing cavity 333 in longitudinal side inside, it is an accent 3331 towards second housing 32 one end, the other end is a socket 3332, can for example, be clogged by a plug mouth part 3333 (immerse oneself in screw piece); This containing cavity 333 is communicated with a spacing elongated slot 334 towards lever 33 outsides, and offers one first pod 335 in these spacing elongated slot 334 outsides; And

One strengthens lockout mechanism 34, as shown in Figure 9, formed by an elastic component 341, a clamping rod 342 and an operating knob 343, the external diameter of this clamping rod 342 is corresponding with accent 3331, on the body of rod of clamping rod 342 and offer one first conjugate foramen 3421, its position can be corresponding with this spacing elongated slot 334, offers one second conjugate foramen 3431 on this operating knob 343; When assembling, by this clamping rod 342 and this elastic component 341 sequentially in socket 3332 receives into containing cavity 333, then by plug mouthful part 3333 interlocking sockets 3332, and prop up the termination of this elastic component 341, to provide the termination that elastic force impels clamping rod 342 to stretch out (shown in accompanying drawing 4) by accent 3331; Because the position of the first conjugate foramen 3421 can correspond to spacing elongated slot 334 places, therefore while this operating knob 343 being placed in to the first pod 335, the second conjugate foramen 3431 of this operating knob 343 corresponds to the first conjugate foramen 3421 of this spacing elongated slot 334 and this clamping rod 342, and can for example, be worn into the second conjugate foramen 3431 of this operating knob 343 and this spacing elongated slot 334 and be completed affixed joint with the first conjugate foramen 3421 of this clamping rod 342 by a fastener 3432 (object of bolt or rivet class); Therefore this clamping rod 342 is only being subject under the situation of this elastic component 341 thrusts (not being subject to other external force) effect, this fastener 3432 can be positioned at the lower end of this spacing elongated slot 334, and outside the termination of this clamping rod 342, stretches out accent 3331 outer (as shown in accompanying drawing 4,8).

When the whole expansion of this folder 3, as shown in accompanying drawing 4,10, now 316,324 of first and second pipe fittings present folded state because of the expansion of this folder 3, then will by this first, two pipe fittings 316, while 324 aligning (folding), process is as accompanying drawing 11, shown in 12, first this first housing 31 rotated by pivot 323 and close up into the state shown in accompanying drawing 11 to the second housing 32, then pull this lever 33 to the first housing 31 direction deflections, its clamping cylinder 332 is taken advantage of a situation cling to be subject to kelly 314 end faces, then clamping cylinder 332 can drive and be subject to kelly 314 to continue deflection and whole crossing after a vertex, form and be subject to kelly 314 by clamping cylinder 332 with oblique the holding of low-angle, and the oblique lock-out state that holds the first housing 31 downwards of lever 33, this as shown in Figure 12, and be first of embodiment of the present invention folder 3 and re-lock effect.

Operated in the process of the first housing 31 direction deflections at this lever 33, strengthen lockout mechanism 34 certainly in company with lever 33 deflections, therefore in the time deflecting into a special angle, as shown in Figure 13, the outer peripheral edges that arrive to affixed cylinder 315 can be touched in the overhanging termination of clamping rod 342, cause clamping rod 342 and can be forced to inside contract and compression elastic piece 341, make clamping rod 342 possess overhanging at any time elastic force; Then in the time pulling this lever 33 and continue to the first housing 31 direction deflection, slide along the outer peripheral edges of this affixed cylinder 315 the overhanging termination of clamping rod 342, now the outer jack 3152 of affixed cylinder 315, because of approaching face (angle with accompanying drawing 13 is sayed) and maintain static upward, supports in outer jack 3152 therefore clamping rod 342 there is no method; In addition, the first interior slot 3123 of wearing on the second movable end 3122 of axle is followed the synchronous deflection of lever 33 because wearing axle 312 together with first, so time in slot 3123 not yet align with outer jack 3152 (shown in accompanying drawing 13).Then when lever 33 is continued deflection by operation to the first housing 31 directions, complete and be subject to first between kelly 314 to re-lock the moment of effect at the clamping cylinder 332 of this lever 33, as shown in Figure 14, interior slot 3123 just turns to the position of this outer jack 3152 of alignment, and clamping rod 342 also just moves to this outer jack 3152 tops, therefore moment clamping rod 342 overhanging terminations are entered (supporting) downwards by this outer jack 3152 and are entered in this interior slot 3123, therefore clamping rod 342 completes clamping effect with outer jack 3152 and 3123 moments of interior slot, this is second of inventive embodiments folder 3 and re-locks effect.

Completing above-mentioned first and second re-locks after effect, second re-locking before effect of not removing clamping between clamping rod 342 and outer jack 3152 and this interior slot 3123, had a mind to or be not intended to movable contact arrive even if first re-locks effect, but still cannot outwards pull by this lever 33, cause first to re-lock effect and cannot remove, therefore re-lock effect and really can increase the safety in utilization of embodiment of the present invention folder 3 entirety by increasing by second.

In the time that user wants first and second pipe fitting 316,324 to fold, must first untie second of this folder 3 and re-lock effect, then operation is untied first and is re-locked effect simultaneously, that is this folder 3 be will untie the operational motion of whole lock-out states time, must will untie the second action that re-locks effect and untie the first coherent operation of action that re-locks effect.First when user holds this lever 33 with palm, must first with finger, the operating knob 343 of strengthening lockout mechanism 34 be promoted laterally, make this fastener of interlock 3432 drive these clamping rods 342 to inside contract (can compress this elastic component 341), the termination of this clamping rod 342 is departed from and interior slot 3123 and outer jack 3152 between clamping effect (that is untie second re-lock effect); Then this lever 33 is outwards pulled downwards, its clamping cylinder 332 is driven is subject to kelly 314 to extrinsic deflection, in this process, clamping cylinder 332 drives and crossed after a vertex by kelly 314, lever 33 throws off (recovering the state shown in accompanying drawing 11) with being subject to kelly 314, therefore first re-lock effect and also untie, and can carry out the jackknife action of 316,324 of first and second pipe fittings.

The present invention is intended to emphasize that the folder of folding bicycle has can strengthen second of locking action and re-lock effect, furthermore, first re-lock effect be that folder should have substantially, can have a variety ofly so can reach the first contexture that re-locks effect, but not be feature of the present invention; Feature of the present invention is to have had the first folder that re-locks effect, has more and can produce the second contexture that re-locks effect.The folder 3 of above-described embodiment is disclosed in and produces first and re-lock and do the used time, more simultaneously by strengthening the clamping rod 342 in lockout mechanism 34, enter (supporting) by its overhanging termination downwards by outer jack 3152 and enter in interior slot 3123 to reach clamping, re-lock effect to form second of folder 3.

Under same function principle, why the present invention can reach second and re-lock effect in fact, the most important affixed cylinder 315 that is to be provided with this outer jack 3152 and the first housing 31 present affixed state between the two, therefore outer jack 3152 stays in fixed position, while arrival etc. clamping rod 342 deflections in lockout mechanism 34 to be strengthened, enter the interior generation clamping of this outer jack 3152 effect, so complete second and re-lock effect.As for the existence of the interior slot 3123 on the second movable end 3122, to be connected to this outer jack 3152 the inners, enter to produce the second clamping degree of depth that re-locks effect, therefore this interior slot 3123 tool booster actions and auxiliary effect, not imperative parts to deepen clamping rod 342.
