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, particularly relate to a kind of folder for folding bicycle with double locking effect.

Background technology

At present, folding bicycle is commonly between pipe fitting and is equiped with folder, 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 (being folded towards down in order to by handlebar stem) or seat bar (being folded towards down in order to by seat cushion), and the position that its contexture and installing use is more. The folder installed on current folding bicycle, being usually point has left and right housing, and wears and pivot joint by an axostylus axostyle in side so that can close up between the housing of left and right or do expansion action with this axostylus axostyle for axle center; A Quick Release group then it is provided with in the non-pivot joint side of left and right housing, left and right housing when left and right housing closes up, can be produced locking action by this Quick Release group, makes the left and right housing cannot easy disengagement voluntarily, therefore must untie locking action via operating this Quick Release group, just left and right housing can be launched. The folder installed on existing folding bicycle is distinguished on using mainly following two kinds of states:

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

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

By the produced locking action of Quick Release group itself, the folder installed on existing folding bicycle, when being closed up by left and right housing via operating this Quick Release group with the left and right housing generation locking action to folder, is generally called that first re-locks effect. because general Quick Release group all has a lever, to facilitate operation Quick Release group produce locking action or untie locking action, that is no matter be to produce locking action or to untie locking action, capital operates this lever, therefore the folder of the first weight (substance) locking action is only had in actual use, this lever can be there is and easily offset the defect of (untiing locking) because shaking or touched unintentionally (or hitting), especially folding bicycle is advanced mobile in the use environment of regular vibrations, if therefore this lever offsets suddenly and unties the locking of folder in incognizance, probably rider will be caused to produce serious disaster.

Therefore the folding bicycle folder of tool double locking effect was namely had to produce later, it namely it is the folding bicycle folder 1 of a kind of common tool double locking effect as shown in the first figure, it has left shell 11 and a right shell body 12, engages with one first and second pipe fitting 111,121 respectively; Left and right housing 11,12 is worn and pivot joint by an axostylus axostyle in side so that left and right housing 11,12 can close up or do expansion action with this axostylus axostyle for axle center; Then being provided with a Quick Release group 13 in the non-pivot joint side of left and right housing 11,12, substantially have a lever 131 outside it, namely the intraware in order to operate this Quick Release group 13 changes and uses; When left and right housing 11,12 closes up, this lever 131 can be pulled and close up to the second pipe fitting 121 direction, so that left and right housing 11,12 is produced first by the intraware of this Quick Release group 13 re-locks effect; Additionally then being installed with a card body 14 outside this second pipe fitting 121, formed for having the elastic material of extension, opening part does recessed shape, can touch this card body 14 when this lever 131 closes up to the second pipe fitting 121 direction, and inwardly clamp-on to position; Therefore by this card body 14, the grasping of lever 131 is reached second and re-lock effect. But its shortcoming is in that this card body 14 is not durable, use its extension elasticity and rapid drawdown soon, cause second to re-lock and act on loose and show for not good.

It is then the folding bicycle folder 2 of another kind of common tool double locking effect as shown in the second figure, there is left shell 21 and a right shell body 22 equally, engage with one first and second pipe fitting 211,221 respectively; Left and right housing 21,22 is worn and pivot joint by an axostylus axostyle in side so that left and right housing 21,22 can close up or do expansion action with this axostylus axostyle for axle center; Then it is provided with a Quick Release group 23 in the non-pivot joint side of left and right housing 21,22, outside it, is operated the variation action of this Quick Release group 23 intraware by a lever 231; When left and right housing 21,22 closes up, pull this lever 231 and close up the intraware that can make this Quick Release group 23 to the second pipe fitting 221 direction and left and right housing 21,22 is produced first re-lock effect; Additionally, this lever 231 offers a jack 232, and this jack 232 place contiguous is equiped with a keeper 24 can pulled and can deflect up and down on this second pipe fitting 221, mainly bottom it, there is a clipping block 241, therefore when this lever 231 closes up completely to the second pipe fitting 221 direction, this keeper 24 can be pulled deflect to lever 231 direction, as shown in the third figure so that this clipping block 241 supports and positions into this jack 232; Therefore by this clipping block 241, the clip of lever 231 is reached second and re-lock effect. Its shortcoming is then in that this keeper 24 is because being be simply pivotally connected on this second pipe fitting 221, therefore use procedure is easily loose due to regular vibrations, cause when operating folding bicycle and doing jackknife action, proficiency must be had to turn round and look at this keeper 24 do not fall so that operation folding bicycle does folding action and becomes extremely to have some setbacks. Furthermore, when this keeper 24 is loose, also it is likely to occur in the process of riding because the clipping block 241 of this keeper 24 jumps out of this jack 232, and makes second to re-lock effect and release suddenly, related cause uncertain danger.

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

One lever 33, is sheathed on described second by an engagement block 331 and wears on axle 322; Contiguous second housing 32 place of lever 33 is horizontally arranged with the clamping cylinder 332 of a cylindrical shape, then, as shown in Figure 9, this lever 33 offers a containing cavity 333 inside longitudinal side, it is an accent 3331 towards second housing 32 one end, the other end is then a socket 3332, can be filled in mouth part 3333 (such as immerse oneself in screw piece) by one and be clogged; This containing cavity 333 connects out a spacing elongated slot 334 outside lever 33, and offers a pod A335 outside this spacing elongated slot 334;And

One strengthens locking mechanism 34, as shown in Figure 9, it is made up of elastic component 341, 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 joint hole 3421, its position can be corresponding with this spacing elongated slot 334, and this operating knob 343 offers one second joint hole 3431; During assembling, sequentially received in containing cavity 333 from socket 3332 by this clamping rod 342 and this elastic component 341, then by plug mouth part 3333 interlocking socket 3332, and prop up the termination of this elastic component 341, to provide the termination that elastic force promotes clamping rod 342 can be stretched out (shown in accompanying drawing 4) by accent 3331; Because the first position engaging hole 3421 can be mapped to spacing elongated slot 334 place, when therefore this operating knob 343 being placed in pod A335, the second of this operating knob 343 engages hole 3431 and namely corresponds to the first joint hole 3421 of this spacing elongated slot 334 and this clamping rod 342, and can be worn by a fastener 3432 (such as the object of bolt or rivet class) and engage hole 3431 and this spacing elongated slot 334 into the second of this operating knob 343 and engage hole 3421 with the first of this clamping rod 342 and complete affixed joint; Therefore this clamping rod 342 be limited only by this elastic component 341 thrust (by other external force) act on when, this fastener 3432 can be positioned at the lower end of this spacing elongated slot 334, and stretches out accent 3331 outer (as shown in accompanying drawing 4,8) outside the termination of this clamping rod 342.

This folder 3 whole launch time as shown in accompanying drawing 4,10, now present folded state because of the expansion of this folder 3 between first and second pipe fitting 316,324, then will by this first, two pipe fittings 316, 324 when carrying out aligning (not folded), process is accompanying drawing 11 such as, shown in 12, first this first housing 31 is 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 deflect to the first housing 31 direction, make its clamping cylinder 332 take advantage of a situation and cling to by kelly 314 end face, then after clamping cylinder 332 can drive and be continued deflection by kelly 314 and cross a peak eventually, formed and held by kelly 314 by clamping cylinder 332 so that low-angle is oblique, and lever 33 holds the lock-out state of the first housing 31 obliquely downwards, this is as shown in Figure 12, and be the first of embodiment of the present invention folder 3 and re-lock effect.

In the process that this lever 33 is deflected to the first housing 31 direction by operation, strengthen locking mechanism 34 certainly namely to deflect in company with lever 33, therefore when deflecting into a special angle, as shown in Figure 13, the outer peripheral edge arriving to affixed cylinder 315 can be touched in the overhanging termination of clamping rod 342, cause clamping rod 342 can be forced to inside contract and compression elastic piece 341, make clamping rod 342 possess elastic force overhanging at any time, then when pulling this lever 33 and continuing to the first housing 31 direction deflection, namely the overhanging termination of clamping rod 342 slides along the outer peripheral edge of this affixed cylinder 315, now the outer jack 3152 of affixed cylinder 315 is because of approaching face upward (angle with accompanying drawing 13) and maintain static, therefore clamping rod 342 there is no method and supports in outer jack 3152, it addition, first wears interior slot 3123 on the second movable end 3122 of axle and follows lever 33 synchronize deflection because wearing axle 312 together with first, so time interior slot 3123 not yet align (shown in accompanying drawing 13) with outer jack 3152. then when lever 33 is continued deflection by operation to the first housing 31 direction, clamping cylinder 332 at this lever 33 completes and is re-locked the moment of effect by first between kelly 314, as shown in Figure 14, interior slot 3123 just turns to the position of this outer jack 3152 that aligns, and clamping rod 342 also just moves to above this outer jack 3152, therefore namely the overhanging termination of moment clamping rod 342 is entered downwards (supporting) entered in this interior slot 3123 by this outer jack 3152, therefore namely clamping rod 342 completes clamping effect with outer jack 3152 and interior slot 3123 moment, what this was inventive embodiments folder 3 second re-locks effect.

Complete above-mentioned first and second re-lock effect after, before not releasing between clamping rod 342 and outer jack 3152 and this interior slot 3,123 the second of clamping and re-locking effect, contacted by intentionally or accidentally dynamic even if first re-locks effect, but still cannot outwards pull by this lever 33, cause first to re-lock effect cannot release, therefore re-lock effect by increase by second and really can increase the safety in utilization of embodiment of the present invention folder 3 entirety.

When user is wanted time folding for first and second pipe fitting 316,324, must first untie this folder 3 second re-locks effect, then operation is untied first and is re-locked effect simultaneously, that is this folder 3 is when carrying out the operational motion untiing whole lock-out state, it is necessary to re-lock the action of effect by untiing second and untie the first action consistent operation re-locking effect. During first by person with this lever 33 of palm when held, first with finger, the operating knob 343 strengthening locking mechanism 34 must be promoted laterally, this fastener 3432 of gearing is made to drive this clamping rod 342 to inside contract (this elastic component 341 can be compressed) so that the termination of this clamping rod 342 departs from and clamping effect between interior slot 3123 and outer jack 3152 (that is untie second re-lock effect); Then this lever 33 is outwards pulled downwards, make its clamping cylinder 332 drive to be deflected outward by by kelly 314, after clamping cylinder 332 drives and is crossed a peak by kelly 314 in the process, lever 33 namely with disengaged (recover accompanying drawing 11 shown in state) by kelly 314, therefore first re-lock effect and also untie, and the jackknife action between first and second pipe fitting 316,324 can be carried out.

The second of locking action can be strengthened re-lock effect it is contemplated that emphasize that the folder of folding bicycle has, furthermore, namely first re-lock effect be that folder substantially should have, can have a variety of so the first contexture re-locking effect can be reached, but not be the feature of the present invention; The feature of the present invention is then in that had the first folder re-locking effect, has more and can produce the second contexture re-locking effect. The folder 3 of above-described embodiment is disclosed in generation first when re-locking effect, more simultaneously by strengthening the clamping rod 342 in locking mechanism 34, being entered downwards (supporting) by its overhanging termination by outer jack 3152 to enter in interior slot 3123 to reach clamping, second to form folder 3 re-locks effect.

Under identical action principle, why the present invention can reach second and re-lock effect in fact, affixed state is presented between both the most important affixed cylinder 315 being in that to be provided with this outer jack 3152 and the first housing 31, therefore outer jack 3152 stays in fixed position, when deflecting arrival etc. the clamping rod 342 in locking mechanism 34 to be strengthened, enter in this outer jack 3152 and produce clamping effect, so namely complete second and re-lock effect. Existence as the interior slot 3123 on the second movable end 3122, it is be connected to this outer jack 3152 the inner, entering to produce the second clamping degree of depth re-locking effect deepening clamping rod 342, therefore this interior slot 3123 has booster action and auxiliary effect not required that they be so parts.

Therefore can there is the change on many contextures between both affixed cylinder 315 and the second movable end 3122, and all in the scope of the claims of the present invention. Refer to shown in accompanying drawing 15, affixed cylinder 315 is inserted in the second slot 3112, and radially placed the fitting 3151 into this first housing 31 wall body by one and push against, to present affixed state between both the first housings 31, then the second movable end 3122 is planted and is presented socket state in this affixed cylinder 315, this affixed cylinder 315 offers an outer jack 3152 penetrated, but this second movable end 3122 is then for smoothing appearance, does not offer any slot;Therefore, when the clamping rod 342 strengthened in locking mechanism 34 arrives in company with lever 33 deflection, namely reach second in entrance outer jack 3152 and re-lock effect, so namely without the existence of this interior slot 3123, but still second can be reached and re-lock effect.

Then, refer to shown in accompanying drawing 16, affixed cylinder 315 is inserted in the second slot 3112, and radially placed the fitting 3151 into this first housing 31 wall body by one and push against, to present affixed state between this both first housing 31, this affixed cylinder 315 forms a pod B3153 towards second movable end 3122 one end, and therefore the second movable end 3122 is planted with short size and presented socket state in this pod B3153; Or, it is also possible to being designed to this second movable end and form a pod B towards affixed cylinder one end, then this affixed cylinder is planted and is presented socket state in this pod B; Affixed cylinder 315 offers an outer jack 3152, but the second movable end 3122 does not then set any slot; Therefore, when the clamping rod 342 strengthened in locking mechanism 34 arrives in company with lever 33 deflection, equally namely reach second in entrance outer jack 3152 and re-lock effect.

The position that the folder 3 of the present invention is installed on folding bicycle and uses is not limit by arresting, except being installed on main car frame (person described above, in order to by vehicle frame folding) outward, can also be installed between handlebar stem and front fork tube, in order to handlebar stem is folded towards down, this is namely as shown in Figure 17, folder 3 is installed between handlebar stem 41 and front fork tube 42, so when implementation is same as aforesaid operational means and step, can pass through handlebar stem 41 and front fork tube 42 to be folded by the action launched by folder 3, and by handlebar stem 41 and front fork tube 42 being aligned (not folded) by the action closed up by folder 3. therefore, under same configuration composition and constructed principle, the folder 3 of the present invention can certainly be installed on present bar, and reaches the effect under being folded towards by seat cushion via identical operational means and step, no longer adds this to repeat.

From described above, namely the present invention provides a kind of folder for folding bicycle with double locking effect, mainly plant into one and the first affixed affixed cylinder of housing on the first breach one medial surface of the first housing, then the first of this first housing is worn the second movable end of axle and plants into socket in this affixed cylinder, this affixed cylinder offers an outer jack, and inside lever longitudinal direction side, offer a containing cavity, for being installed with into a reinforcement locking mechanism; This reinforcement locking mechanism is mainly located in this containing cavity by an elastic component and a clamping rod, and connects an operating knob in side; When first and second housing of folder closes up, and being pulled toward the first housing by lever and carry out first when re-locking effect, bottom this clamping rod, termination can deflect this outer jack position of arrival, and namely complete the second of snap engagement with this outer jack and re-lock effect.
