Description

Folding bicycle folder with enhanced locking function (1)

The present invention relates to a folding bicycle folder, and more particularly to a folding bicycle folder which has an enhanced locking function and can greatly improve the safety of use.

According to the conventional folding bicycle, a folding device is often arranged between the pipe fittings, so as to operate the folding actor between the pipe fittings, the common folding device is installed on the main frame (to facilitate folding the frame), the handlebar and The front fork tube (to facilitate folding the handlebar down) or the seatpost (to facilitate folding the seat cushion down), its structural composition and installation position is quite a lot. The folding device installed on the conventional folding bicycle is generally divided into left and right housings, and is pivotally connected on one side by a shaft, so that the left and right housings can be close together or the shaft can be used as an axis. The unfolding action is arranged on the non-pivoting side of the left and right housings, and the quick release group can lock the left and right shells when the left and right shells are close together, so that the left and right shells cannot be easily disengaged by themselves, so It is necessary to unlock the left and right casings by operating the quick release group to unlock the locking effect. Therefore, the folding device installed on the conventional folding bicycle is divided into the following two states in use:
1. When the left and right casings of the folder are close together (regardless of whether the quick release group is locked or unlocked), the two pipe fittings of the folder are not folded.
2. When the left and right casings of the folder are unfolded, the quick-release group must be unlocked, and the two pipe fittings of the folder are folded.
The folding device installed on the folding bicycle, when the left and right casings are close together, is operated to lock the left and right casings of the folder by operating the quick release group, and generally the locking effect generated by the quick release group itself is called For the first weight lock effect. Because the general quick release group has an operation handle, so as to facilitate the operation of the quick release group to generate a locking action or unlock the locking function, that is, whether the locking action or the unlocking action is to be performed, the operation handle is operated, In the actual use, the folder having only the first weight (single weight) locking function may have the advantage that the operation handle is easily displaced (unlocked) due to vibration or being inadvertently touched (or hit). In particular, the folding bicycle travels in the environment of frequent vibrations, so if the handle is suddenly unconsciously undisturbed and the lock of the folder is unlocked, the rider may be seriously catastrophic.
Therefore, a folding bicycle folding device having a double locking function is produced, and as shown in the first figure, a folding bicycle folding device 1 having a double locking function is provided, which has a left casing 11 and a right casing 12. Separately engaged with a tube member 111, 121; the left and right housings 11, 12 are pivotally connected on one side by a shaft so that the left and right housings 11, 12 can be brought together or unfolded with the shaft as an axis. Actuating; a quick-release group 13 is disposed on the non-pivoting side of the left and right housings 11, 12, and the outside thereof obviously has an operating handle 131, that is, an internal component for operating the quick-release group 13; When the 11 and 12 are close together, the operating handle 131 can be pulled toward the tubular member 121 to make the internal components of the quick release group 13 have a first re-locking effect on the left and right housings 11 and 12; A card body 14 is externally fixed, and is formed by a material having stretch elasticity. The opening is retracted. When the handle 131 is close to the tube member 121, the card body 14 is touched and pushed inward for positioning. Therefore, the second weight is achieved by the clamping of the operating handle 131 by the card body 14 Fixed role. However, the only reason for this is that the card body 14 is not weather-resistant, and its stretch elasticity is dip suddenly after use, resulting in looseness of the second weight locking effect and being unfavorable.
As shown in the second figure, there is another conventional folding bicycle folder 2 having a double locking function, which also has a left casing 21 and a right casing 22, respectively engaged with a pipe member 211, 221; left and right casings The bodies 21 and 22 are pivotally connected on one side by a shaft so that the left and right housings 21 and 22 can be brought together or the shaft is pivoted; the non-pivoting sides of the left and right housings 21 and 22 Then, a quick release group 23 is disposed, and the external operation of the quick release group 23 is operated by an operation handle 231; when the left and right housings 21 and 22 are closed, the operation handle 231 is pulled toward the tube member 221 to be closed. The internal components of the quick release group 23 have a first re-locking effect on the left and right housings 21 and 22; another, a socket 232 is defined in the handle 231, and a mounting hole 232 is disposed on the tubular member 221. The positioning member 24 that can be deflected up and down is mainly provided with a latching block 241 at the bottom thereof. Therefore, when the operating handle 231 is completely close to the tubular member 221, the positioning member 24 can be deflected and deflected toward the operating handle 231. As shown in the third figure, the card block 241 is brought into the jack 232 for positioning; This block 241 by engaging the latch lever to the card 231 to reach the second re-locking action. The missing part is that the positioning member 24 is simply pivotally connected to the tube member 221, so the use process is often subjected to vibration and is easy to loose, so that when the folding bicycle is operated to perform the folding action, the positioning member 24 must be taken care of. Falling down makes it extremely uncomfortable to operate the folding bike for folding. Moreover, when the positioning member 24 is loose, it may happen that the second locking operation is suddenly released due to the snapping of the latching member 232 by the latching block 241 of the positioning member 24 during the riding process, and the connection is unpredictable. The danger.

With regard to the above-mentioned objectives, the technical means and the achievable effects of the above-mentioned purposes, the following preferred embodiments are described in detail with reference to the accompanying drawings, which are fully understood.
Referring to the fourth to seventh embodiments, the first embodiment of the present invention is a folder 3 for use on a folding bicycle. The structure comprises: a first casing 31 having a notch 311 in a middle thereof. A through shaft 312 is laterally inserted into the opening, and a torque elastic member 313 is sleeved on the through shaft 312, and a latching rod 314 is formed in the center thereof. The head 3141 is arc-shaped, and the through shaft 312 is movable. (ie, not fixed), but limited by the torsion elastic member 313, the shaft 312 (and the click lever 314) will assume a certain angle position when not subjected to other external forces (as shown in the fourth figure). a positioning rod 315 (which is used for a positioning member, which can be screwed by a screw) is disposed on the outer surface of the first casing 31 on the outer surface of the first casing 31. The outer portion of the first casing 31 is fixed to a pipe member 316 (shown in the seventh figure);
A second housing 32 is pivotally connected to the first housing 31 by a pivot 323. The second housing 32 has a notch 321 in the non-pivoting side, and the opening is laterally implanted. The second housing 32 is fixedly connected to the shaft 322, and a tube member 324 is fixed on the outside of the second housing 32 (shown in FIG. 7);
An operating handle 33 defines an arc-shaped latch socket 331 adjacent to the second housing 32, and is sleeved on the threading shaft 322 by an engaging block 332 which is attached to the engaging block 332. A through slot 3321 (shown in FIG. 6 ) is disposed transversely for the through shaft 322 to pass through, so that the engaging block 332 can be freely rotated with the through shaft 322 as an axis; the operating handle 33 is on the longitudinal side. An accommodating cavity 333 is defined in the interior of the second housing 32. The accommodating cavity 333 is connected to the outer side of the operating handle 33 to extend a limiting slot 334. A socket 335 is provided on the outer side of the 334 (shown in FIG. 6); and a reinforcing locking mechanism 34, as shown in the sixth figure, is composed of an elastic member 341, a latching rod 342 and an operating button 343. The 341 is received in the accommodating cavity 333 of the operating handle 33, so that the inner end end is abutted into the inner wall of the accommodating cavity 333, and the latching lever 342 is further received in the accommodating cavity 333. Abutting the other end of the elastic member 341; the engaging rod 342 has an engaging hole 3421 formed on the rod body, and the other end protrudes outside the opening 3331 (shown in the fourth figure);
The position of the engaging hole 3421 corresponds to the limiting slot 334. Therefore, when the operating button 343 is placed in the socket 335, the upper engaging hole 3431 of the operating button 343 corresponds to the limiting slot 334. The engaging hole 3421 of the latching lever 342 can be inserted into the engaging hole 3431 of the operating button 343 and the long slot 334 by an engaging member 3432 (for example, a bolt or a rivet type object). The engaging hole 3421 of the 342 completes the fixed joint; therefore, the engaging member 342 is located at the lower end of the limiting long groove 334 in the case where the engaging member 342 is only subjected to the thrust of the elastic member 341 (not being subjected to other external force). And the end of the card mast 342 protrudes outside the cavity 3331 (shown in Figures 4 and 5).
When the folder 3 is fully deployed, as shown in the fourth and seventh figures, the two tubes 316, 324 are folded in a state due to the expansion of the folder 3; then the tubes 316, 324 are aligned (not When folding, the process is as shown in the eighth and ninth figures. First, the first housing 31 is rotated by the pivot 323 to the second housing 32 to form the state shown in the eighth figure, and then the operation is pulled. The handle 33 is deflected toward the first housing 31, so that the latching socket 331 covers the arcuate head 3141 of the latching lever 314, and then continues to deflect the latching lever 314 to pass the highest point. The arcuate head 3141 of the card shank 314 is clamped by the card socket 331, and the card shank 314 is obliquely pressed downward against the locked state of the first housing 31, such as The ninth figure shows the first relocking action of the folder 3 of the first embodiment of the present invention.
During the deflection of the operating handle 33 toward the first housing 31, the reinforcing locking mechanism 34 is of course deflected with the operating handle 33, so that when deflected to a specific angle, as shown in the tenth figure, the latch The bottom edge of the protruding end of the rod 342 can reach the positioning rod 315 on the first casing 31, so the clamping rod 342 is forced to retract to compress the elastic member 341, and then the operating handle 33 is directed to the first shell. When the direction of the body 31 continues to deflect, as shown in the eleventh figure, the latching lever 342 is more retracted to compress the elastic member 341, and finally the cassette socket 331 of the operating handle 33 is completed and clicked. At the moment when the first weight is locked between the rods 314, the bottom edge of the protruding end of the clamping rod 342 just passes over the positioning rod 315, so that the clamping rod 342 and the positioning rod 315 are instantaneously engaged, such as the twelfth As shown in the figure, this is the second re-locking action of the folder 3 of the first embodiment of the present invention.
After the first and second locking functions are completed, the longitudinal first locking action is intentionally or unintentionally touched before the second re-locking action of the snapping between the latching lever 342 and the positioning rod 315 is released, but still cannot be The operation handle 33 is pulled outward, so that the first re-locking action cannot be released, so that the overall safety of the folder 3 of the present embodiment can be increased by increasing the second re-locking effect.
When the user wants to fold the two pipe members 316, 324, the second re-locking operation of the folder 3 must be untied first, and then the first re-locking action is unwrapped at the same time, that is, the folder 3 is to be unwound. In the operation of all the locked states, the action of unlocking the second re-locking action and the action of unlocking the first re-locking action must be consecutively operated. When the user grasps the operating handle 33 with the hand, the operating button 343 of the reinforcing locking mechanism 34 must be pushed outward by the finger, so that the engaging member 3432 can be engaged to retract the latching lever 342 (which will compress the elasticity). 341), the end of the latching lever 342 is disengaged from the positioning rod 315 on the first housing 31 (ie, the second re-locking action is released); then the operating handle 33 is directed The outer handle is pulled downward to cause the latching socket 331 to deflect the latching lever 314 outwardly. In the process, the latching socket 331 drives the arcuate head 3141 to pass a highest point, and the operating handle 33 is The card mast 314 is disengaged (recovering the state shown in the eighth figure), so that the first re-locking action is also released, and the folding operation between the two pipe members 316, 324 can be performed.
The present invention aims to emphasize that the folding bicycle folding device has a second re-locking function that can enhance the locking effect. Further, the first re-locking function is basically necessary for the folding device, so that the first re-locking effect can be achieved. The composition of the structure can be many, not the characteristics of the original creation; the feature of this creation is that the folder has the first locking function, and has a structural component that can produce the second locking effect. The folder 3 of the first embodiment described above is disclosed when the first re-locking action is generated, and at the same time, by the latching lever 342 of the reinforcing locking mechanism 34, the bottom edge of the extending end is over a positioning rod 315. The card is snapped to form a second re-locking action of the folder 3.
In the second embodiment of the present invention, the same component numbers are used in the second embodiment of the present invention, and the components are not described in detail. As shown in the thirteenth and fourteenthth drawings, the folder 3 of the second embodiment of the present invention is different from the first embodiment in that a sliding groove 317 is formed rearward from the leading edge on the outer surface of the first casing 31. Until a deep positioning slot 318 (for the purpose of a positioning member). In use, the first housing 31 is also rotated toward the second housing 32 by the pivot 323, and then the operating handle 33 is deflected toward the first housing 31 to complete the first and second housings 31. a first locking action of 32; during the deflection of the operating handle 33 toward the first housing 31, the reinforcing locking mechanism 34 is deflected to a specific angle with the operating handle 33, as in the fifteenth It is shown that the bottom edge of the protruding end of the latching lever 342 touches the leading edge of the sliding slot 317, so the latching lever 342 is forced to retract to compress the elastic member 341 and is driven along the sliding slot 317. Traveling, and then at the moment when the operating handle 33 completes the first re-locking action between the first and second housings 31, 32, the bottom edge of the protruding end of the latching lever 342 just passes over the sliding slot 317 The snapping is achieved in the positioning slot 318. As shown in the sixteenth embodiment, this is the second re-locking action of the folder 3 of the second embodiment. As for the folding state of the folder 3 of the second embodiment, the action of continuously releasing the second re-locking action and the first re-locking action is the same as that of the first embodiment.
The present invention, regardless of the folder 3 of the first embodiment or the second embodiment, is installed on the folding bicycle and is not restricted, except that it can be mounted on the main frame (as described above, The frame may be folded between the handle bar and the front fork tube for folding the handle bar downward, that is, as shown in FIG. 17, the folder 3 is mounted on the handle bar 41 and the front. When the fork tube 42 is used, when the operation means and steps are the same as those described above, the handle bar 41 and the front fork tube 42 can be folded by the action of expanding the folder 3, and the action of folding the folder 3 together The handlebar 41 is aligned with the front fork tube 42 (not folded). Therefore, under the same structural composition and the same technical principle, the folding device 3 of the present invention can of course be mounted on the seat post, and the folding operation of the seat cushion can be achieved through the same operation means and steps. Narration.
It can be seen from the above description that the present invention provides a folding bicycle folder with a locking function, which is mainly provided with a positioning member for locking on the outer surface of the first casing, which can be a positioning rod or a positioning groove, and An accommodating cavity is defined in the longitudinal side of the operating handle for receiving a reinforcing locking mechanism. The reinforcing locking mechanism is mainly provided with an elastic member and a latching rod disposed in the receiving cavity and connected to the side. The operating button; when the first and second housings of the folder are closed together, and the operating handle is pulled to the first housing for the first locking operation, the bottom end of the clamping rod is engaged with the positioning member.
