Description

  The present invention relates to a bicycle capable of adjusting the height and angle of a handlebar.

  In general, the height and angle of the bicycle handlebar is fixed and cannot be adjusted. However, to improve the comfort of the user when riding the bicycle, or to use various bicycles (for example, outdoor riding or urban riding) Bicycles have been developed that can adjust the height and angle of the handlebar according to the riding speed of the horse and the riding speed.

  For example, European Patent No. 0 734 447 discloses an adjustable connecting member for use in connecting a bicycle handlebar and turning stem. The adjustable connecting member includes a connecting member body and a fitting mechanism. Among them, the connecting member main body includes a connecting portion, and a handle bar is connected to the connecting portion, and the relative position of the handle bar can be adjusted by adjusting the fitting mechanism. However, there is only one connecting member main body, and when the user rides a bicycle, the weight of the upper body often hangs on the handlebar. Later, fatigue damage may occur in the connecting member body. And when you want to attach a bicycle accessory to the bicycle, it is necessary to attach it to a place other than the center of the handlebar, the appearance is not harmonious, the aesthetics are impaired, and when the bicycle accessory is a forehead etc. The front cannot be illuminated.

  U.S. Pat. No. 6,584,872 discloses a bicycle handle mounting member. The handlebar-display unit support part is a pair of leg designs (substantially U-shaped), a display receiving space is formed in the middle of the handlebar-display unit support part, and the display unit can be installed. The handlebar-display unit support part and the handlebar can be connected to adjust the height of the handlebar. However, the handlebar needs to be divided into two according to the handlebar-display unit support, and when adjusting the height of the handlebar, it is limited to the structure, and the handlebar angle can be adjusted simultaneously. It was necessary to loosen and adjust the screw separately. This not only has a complicated structure and high cost, but also has the disadvantage that the height and angle of the handlebar cannot be adjusted simultaneously, which is very inconvenient for the user.

  Therefore, there is a need to provide a bicycle that has improved the above-mentioned drawbacks.

It is sectional drawing of the safety control apparatus of the bicycle of this invention. It is sectional drawing of the safety control apparatus of the bicycle of this invention, and shows the change from the fastening state of a quick opening / closing member to a non-tightening state.

  In order to more clearly show the above-described and other objects, features, and advantages of the present invention, the best embodiment will be described below in detail with reference to the drawings.

  FIG. 1 is an external view of a bicycle according to the present invention. FIG. 2 is another external view of the bicycle according to the present invention, and shows a state where the handle bar is at a position different from that in FIG. As shown in FIGS. 1 and 2, the bicycle 1 of the present invention includes a front wheel 11, a rear wheel 12, a pedal transmission device 13, a direction control device 2, and a frame 14 that connects the above-described members. Used to control the direction of the front wheel 11. The emphasis of the present invention is that the position of the handle bar 20 in the direction control device 2 can be adjusted as shown in FIGS. 1 and 2, and the direction control device 2 will be described below.

  FIG. 4 is a three-dimensional view of the bicycle direction control device of the present invention. As shown in FIGS. 1 to 4, the direction control device 2 mainly includes a handle bar 20, a turning stem 30, two adjustment bars 40, and a quick opening / closing member 50.

  The turning stem 30 is coupled to the frame 14 (see FIG. 1). FIG. 3 is a three-dimensional exploded view of the bicycle direction control device of the present invention. As shown in FIG. 3, the turning stem 30 includes a stem 31 and a lateral bar 32. The stem 31 and the lateral bar 32 are coupled, and the lateral bar 32 is substantially parallel to the handle bar 20. In an embodiment of the present invention, the stem 31 and the lateral bar 32 are substantially vertical, and the stem 31 and the lateral bar 32 are connected by, for example, a welding method.

  As shown in FIG. 4, in order to improve the connection strength and stability between the handle bar 20 and the turning stem 30, it is assumed that it is larger than (mm) in one embodiment of the present invention. This width is larger than the width used in the current technology (for example, when connecting the connecting member body of European Patent No. 0 734 447 and the handle bar 20, the width of the connecting member body is at most only 25 mm). Note that if the support width 40d is too narrow, excellent connection strength and stability between the handle bar 20 and the turning stem 30 cannot be obtained.

  For this reason, when compared with the bicycle 1 of the present invention and European Patent No. 0 734 447, the bicycle 1 of the present invention does not simply provide one more adjustment bar 40. European Patent No. 0 734 447 or the current technology does not present such a wide support width 40d. The greatest reason why the bicycle 1 of the present invention uses the two adjustment bars 40 is to present a sufficiently wide support width 40d.

  Each adjustment bar 40 includes an adjustment base 41, a first clamp part 411, and a second clamp part 412. Among them, the first clamp part 411 and the second clamp part 412 are provided at both ends of the adjustment base 41. Both ends of the lateral bar 32 are clamped to each first clamp part 411, and the handle bar 20 is clamped to each second clamp part 412.

  In the embodiment, the clamp portions 411 and 412 are matched to the shapes of the horizontal bar 32 and the handle bar 20. The clamp portions 411 and 412 have a circular hole shape, and each clamp portion 411 and 412 includes slit portions 411a and 412a.

  The quick opening / closing member 50 is connected to each adjustment bar 40, and the quick opening / closing member 50 is used to control the clamp state of each first clamp part 411 and each second clamp part 412. In one embodiment of the present invention, the quick opening / closing member 50 can control the clamping state of each of the first clamp portions 411 and each of the second clamp portions 412 in a synchronous manner, which will be described in detail below.

  The quick opening / closing member 50 includes two eccentric quick release members 51. Each eccentric quick release member 51 includes a pivoted eccentric head 511 and a pull bar 512. The pivoting eccentric head 511 is located at each of the second clamp portions 412. Each pull bar 512 is formed in each adjustment bar 40 and pivotally attached to the pivot eccentric head 511. Each eccentric quick release member 51 controls the clamp state (two types of tightening state 58 and non-tightening state 59) of each first clamp part 411 and each second clamp part 412 of each adjustment bar 40, respectively. Since the eccentric quick release member 51 is a conventional technique, the description thereof is omitted here. In addition, although it is very convenient to control the clamp using the eccentric quick release member 51, the safety of the eccentric quick release member 51 does not reach the bolted connecting member. For this reason, the bicycle 1 of the present invention provides two eccentric quick release members 51, and in combination with the two adjustment bars 40, achieves a safer and more robust quick opening / closing member 50.

  One of the features of the present invention is that the quick opening / closing member 50 further includes a lateral connection portion 52, connects the two eccentric quick release members 51, and operates the two eccentric quick release members 51 in a synchronous manner. . FIG. 6 is a side sectional view showing an operation of opening the quick opening / closing member of the bicycle of the present invention. When the user opens the horizontal connecting portion 52 upward and moves away from the horizontal bar 32, the relative positions of the pivoting eccentric heads 511, the pull bars 512, and the adjusting bars 40 change, and the degree of adhesion of the slit portions 411a, 412a. As shown in FIG. 6, the clamp state of each first clamp part 411 and each second clamp part 412 becomes the non-tightened state 59. And when a user returns the horizontal connection part 52 and makes it close to the horizontal bar 32, the clamp state of each 1st clamp part 411 and each 2nd clamp part 412 will recover the clamping | tightening state 58. FIG.

  Another new feature of the present invention is that the lateral connecting portion 52 and the two eccentric quick release members 51 form an opening 53, and a receiving space 21 (see FIGS. 3 and 4) is provided at the center of the handle bar 20. The bicycle accessory 60 (in this embodiment, the front light) can be formed and installed in the receiving space 21. Since the receiving space 21 itself is a part of the handle bar 20, the bicycle accessory 60 can be conveniently and securely installed on the handle bar 20. And since the receiving space 21 is in the central part of the handle bar 20, a bicycle accessory 60 suitable for installation in the central part of the handle bar 20, such as a front light, a distance meter, a speedometer, a photographing device, A satellite navigation device or the like can be installed here. Further, as a better design of the bicycle accessory 60, there is a design integrated with the quick opening / closing member 50. As shown in FIG. 5, the opening 53 of the quick opening / closing member 50 and the receiving space 21 of the handle bar 20 are provided in a bicycle. The accessory 60 and the quick opening / closing member 50 are integrated.

  Please refer to FIG. FIG. 7 is a side view showing that there is no need to adjust the bicycle accessory when adjusting the handlebar position of the present invention. Yet another new feature of the present invention is that when the clamp state of each first clamp part 411 and each second clamp part 412 is the untightened state 59, the user can adjust the position of the handlebar 20 at the same time. The accessory 60 (for example, the front light) is fixed on the handlebar 20, but when the position of the handlebar 20 changes, the user does not need to loosen the bicycle accessory 60 from the handlebar 20. is there. At this time, since the second clamp part 412 and the handle bar 20 form an untightened state 59, when the user grasps the handle bar 20 and lifts it up, the handle bar 20 is rotated relative to the second clamp part 412. Can be moved. Since the bicycle accessory 60 can also be oriented forward as shown in FIG. 7, the design of the present invention is very convenient for the user. From the above, adjusting the handle bar 20 does not affect the angle of the bicycle accessory 60 or the brake handle (not shown).

  FIG. 8 is a sectional view of the bicycle safety control device of the present invention. FIG. 9 is a cross-sectional view of the bicycle safety control device according to the present invention, and shows a change of the quick opening / closing member from the tightening state to the non-tightening state. As shown in FIGS. 3, 8, and 9, in one embodiment of the present invention, the quick opening / closing member 50 further includes a safety control device 54, and the safety control device 54 is installed on the lateral connection portion 52. The safety control device 54 is used to control whether or not the horizontal connecting portion 52 is moved away from the horizontal bar 32. That is, when the user wants to change the quick opening / closing member 50 from the tightening state 58 (FIG. 8) to the non-tightening state 59 (FIG. 9), it is necessary to operate the safety control device 54 first.

  In one embodiment of the present invention, the lateral connecting part 52 includes a plurality of perforations 521 (see FIG. 3). The safety control device 54 includes a slider 541, an elastic member 542 (such as a spring), a plate 543, and a plurality of screw members 544. Among them, the elastic member 542 is installed in any one of the perforations 521, and the screw members 544 are formed in the plate 543 and the perforations 521 and connected to the slider 541. As shown in FIG. 8, in a general situation, one end of the plate 543 is brought into contact with one side of one adjustment base 41. As shown in FIG. 9, when the user wants to adjust the direction control device 2, first, the slider 541 is moved toward one side, and the horizontal connecting portion 52 is raised only after the plate 543 is detached from the adjustment base 41. Open toward and away from lateral bar 32. When the user stops applying the force, the slider 541 and the plate 543 are returned to the original positions by the recovery force of the elastic member 542. Thereby, it can be avoided that the user inadvertently changes the quick opening / closing member 50 from the tightening state 58 to the non-tightening state 59.

  As described above, the present invention has features, means, and effects that are different from those of the prior art. Therefore, it is hoped that a patent can be granted and that it can contribute to society. It should be noted that the above-described embodiments are given only for explanation and illustration, and that the claimed scope of the present invention is not limited to the above-described embodiments according to the claims. .
