Description

 Bicycle standpipe occlusion device with limit  

The present invention relates to the technical field of a bicycle standpipe structure, and more particularly to a bicycle standpipe snap device having a limit position, which provides a pivotal joint of a cross tube of a bicycle combination handlebar pipe at an upper end of the standpipe, and a crimping piece and a bite block. The combination of interlocking and fixing at the upper end of the vertical pipe, and further releasing the loosening operation of the limiting crimping member, and supporting the rigidity of the vertical pipe engaging structure in driving, is an excellent practicality. invention.

The bicycle riser is used to connect the bicycle handle and the important structure of the front fork. Therefore, the design of the riser has a significant influence on the riding comfort and driving safety of a bicycle.

Please refer to Taiwan Patent No. M256857, "Bicycle Standpipe", whose structure is as described for its purpose: "The purpose of this creation is to provide a bicycle standpipe that utilizes the same adjustment action to adjust the angle of the riser. Adjusting the angle of the driver, it is not necessary to adjust the riser angle and the angle of the driver separately with separate adjustment actions, which is quite simple.".

As shown in the fifth and sixth figures of the prior patent, the schematic diagram of the release state and the state of the locked state are respectively shown in the fifth figure in the prior patent (the figure is 100 in the state of release) , that is, the grip 104 is downward), the horizontal tube 80 can be adjusted to a desired angle, and then the angle of the driver (reference numeral 802 in the figure) can be adjusted, and then the grip of the screwing structure (reference numeral 100 in the figure) (reference numeral 104 in the figure) ) Pull up and hold the cross tube (refer to Figure 6 in Figure 80) because the bottom end of the grip is eccentric, which causes the block (reference numeral 91 in the figure) to move upward. On the one hand, the rack (reference numeral 902 in the figure) is meshed with the rack of the straight tube (reference numeral 70 in the figure) (the reference numeral 702 in the figure); on the other hand, the inclined surface (reference numeral 904 in the figure) pushes the push rod (Fig. The slope of the reference numeral 810) (reference numeral 811 in the figure) causes the push rod (reference numeral 810 in the figure) to move forward, causing the curved push surface at the other end (reference numeral 812 in the figure) to abut the driver (reference numeral 802 in the figure). ) to form a tight and fixed.

However, in the screwing structure (reference numeral 100 in the figure) of the prior patent, the grip (reference numeral 104 in the figure) is pulled upward and is in the state of the horizontal tube (refer to the sixth figure in the figure), the grip is In the absence of the limit structure, it is easy to make the grip bar out of the tight state and swing down to the release state of the fifth figure in the bumpy road of the driving, so that the cross tube in the driving (label 80 in the figure) will be like the first The unstable situation and danger of shaking up and down as indicated by the arrows in Figure 5 is the biggest shortcoming of the patent structure in the previous case.

Therefore, how to solve the above-mentioned citation structure of the pre-clawed structure of the grip bar lacks the limit structure, so that the grip bar is out of the tight state in the road bumps of the driving and swings down to the loose state, resulting in instability of the driving and The creators who make improvements to the shortcomings such as danger are the difficult points to be solved for this case.
