Please refer to Fig. 1, the utility model one preferred embodiment bicycle shift gear display device is the handle that is installed in bicycle, and this read out instrument 1 is to be subjected to an operation handlebar 2 interlocks, and can install an adjustment button 3 and be located at end in addition, and can supply installing one control line 4, wherein:

As shown in Figure 2, this operation handlebar 2 is to be combined by line wheel 6, one sleeve pipe 7 and a pivoted housing 8, and wherein this line wheel 6 is provided with a brake surface 61 relatively and is circumferential slopes, and is equiped with a location shell fragment 63, and this line wheel 6 is to connect this control line 4.

Please refer to Fig. 2 to Fig. 5, this read out instrument 1 consists predominantly of:

One body 10 has a central siphon 11 and is sheathed on handle, and a chute 12 is located at the top face position, and an endoporus 15 is located at lower position, and some fasteners 17 fasten for the Location resilient piece 63 of this line wheel 6 in being located in week.

One tumbler 20 is to be hubbed at this body 10 tops, and having 21 pairs on a pivot should be located at the lower end by body 10, one first slotted holes 23, and one second slotted hole 24 is located at the end in addition of this tumbler 20.

One stopper group 30, be the inside of being located at this body 10, have an anchor shaft 31 and be installed in the inside of this body 10, a spring 33 and a push rod 35 are sheathed on this anchor shaft 31 in regular turn, and are provided with one in these push rod 35 tops and lead the tip 37 movable first slotted holes 23 that plug this tumbler 20; Wherein the right-hand end of this push rod 35 is the brake surfaces 61 that are butted on this line wheel 6.

One display part 40, be to be in the chute 12 that en plaque is installed in this body 10, its upper and lower sides is the ora terminalis up and down that is sticked in this chute 12, has to lead the tip 41 and be convexly equipped with downwards for being installed with second slotted hole 24 that is active in this tumbler 20, can be free to slide in the chute 12 of this body 10.

One lid 50 is to be covered on this body 10 tops, has the chute 12 top openings that 51 pairs of watchcases should body 10, and one indicates and has the panel 52 of gear numeral to be located at position on the watchcase 51.

Relevant present embodiment make flowing mode and principle, be described as follows now:

When variable speed operation, must rotate this pivoted housing 8 with hand, making it drive this line wheel 6 rotates, this control line sword is promptly spurred and this line wheel 6 rotates, therefore can operate this change-speed box (figure does not show) start it, the operation of its speed change and start are general modes and do not belong to technology of the present utility model, do not describe in detail in this appearance.

And the start of its speed change gear and demonstration situation, other is described as follows:

Extremely shown in Figure 4 as Fig. 3, the push rod 35 of this stopper group 30 is the elastic force that is subjected to its spring 33, and be held in the brake surface 61 of this line wheel 6 movably, because the brake surface 61 of this line wheel 6 is to be the inclined-plane, make this stopper group 30 produce horizontal straight-line displacement when therefore rotating relatively.

First slotted hole 23 that the tip 37 then can drive this tumbler 20 of leading of this stopper group 30 rotates, therefore what second slotted hole 24 of this tumbler 20 promptly affected this display part 40 leads the tip 41, driving this display part 50 moves in the chute 12 of this body 10, promptly with respect to panel 52 marker locations of this lid 50, and can clearly learn present employed speed change gear.

In addition, the chute of this body also can be set as arc, and can make this display part slide and indicate its gear in the chute of this body equally.

Replenish at this, the tip of leading of this stopper group and display part is respectively to be arranged with a lining (figure does not show) in the utility model, and wherein this each lining is that minimizing free to rotate is ground dynamic resistance and can be made its start more smooth-going.

In addition, as shown in Figure 7, be that this line wheel 6 of expression and sleeve pipe 7 are to be used in combination for individual part; In addition as shown in Figure 8, this line wheel 6A and sleeve pipe 7A can be penetrated one-body molded making with plastic cement again.

By above embodiment explanation, it is as follows to conclude characteristics of the present utility model:

1. this device does not reach indication range applicable to various vehicle speed, can adjust the angle that meets ergonomics, and is difficult for producing the error at visual angle.

2. this device is the outside of being located at this speed changing operating mechanism, so the space of its setting is big and make things convenient for, and can show bigger scope.

3. this device can be designed to the various types of circumference formula or straight line, meeting the demand of various design types, and increases the variety of product.

To sum up institute is old, the utility model bicycle shift gear display device has above-mentioned every characteristics, and is reached many purposes of the present utility model, is to have progressive and practicality at first creation, for ensureing the rights and interests of creator's hammer away, the whence proposes novel patent application in accordance with the law.
