For a complete understanding of the present invention, exemplary embodiments are described in detail below with reference to the figures. The above description represents represents only preferred exemplary embodiments of the invention and is not intended to restrict the claims.

It gets to the 3 , 4th , 5 and 6th Referenced. The present invention discloses a fastening device for bicycle brake handles that are attached to the handlebars 200 of a bicycle and a seat body 10 , a U-shaped elastic clamping portion 20th , a clamping ring 30th and a locking assembly 40 includes. One side of the seat body 10 is pivotable with a bicycle brake handle 100 connected and the other side is with a combination section 11 provided, the combination section 11 according to the curvature of the bicycle handlebar 200 with an arcuate face 12 is provided, the seat body 10 in the perpendicular to the bicycle handlebar 200 standing direction with a combination hole 13 is provided, the to the seat body 10 adjacent upper portion of the combination hole 13 with a polygonal (e.g. hexagonal) delimiting recess 131 is provided, with a wall hole 14th between the combination hole 13 and the arcuate surface 12 is provided, creating the combination hole 13 with the arcuate face 12 is continuously connected and thus the outer peripheral wall of the bicycle handlebar 200 into the wall hole 14th can extend.

The clamping section 20th consists of an elastic non-metallic material such as rubber or plastic. The concave curved surface of the clamping section 20th is on the arcuate surface 12 of the combination section 11 matched so that these together hold the bicycle handlebars 200 include. The wall surface of the seat body 10 removed clamping section 20th is along its curvature with a protrusion 21st Mistake.

The clamping ring 30th is to be clamped on the bicycle handlebar 200 on the combination section 11 matched and has a cover portion 31 , a first clamping portion 32 and a second clamping portion 33 that both extend from the cover section 31 extend forth in the same direction, the cover portion 31 the clamping section 20th covers, the first clamping portion 32 and the second clamping portion 33 each with a first through hole 34 and a second through hole 35 are provided, the cover portion 31 on the ledge 21st of the clamping section 20th coordinated and with a limiting recess 36 is provided, the projection 21st of the clamping section 20th into the delimitation recess 36 is used so that the clamping section 20th can be positioned.

The locking assembly 40 includes a screw tube 41 and one in the screw tube 41 screwed in screw 42 , the screw tube 41 into the combination hole 13 of the seat body 10 is plugged in. One end of the screw tube 41 has a screw head 411 whose diameter is greater than the outer diameter of the threaded pipe 41 is on. The screw head 411 points in the to the screw 42 facing direction an edging section 412 and a polygonal (e.g. hexagonal) positioning section 413 on. The edging section 412 is on the first through hole 34 of the clamping ring 30th and the positioning section 413 on the limiting recess 131 of the seat body 10 Voted. The outside diameter of the skirting section 412 is smaller than the outside diameter of the screw head 411 to make a first push section 414 to define, the first clamping portion 32 of the clamping ring 30th through the first pressing section 414 is pressed down. The wall thickness of the pipe wall of the screw pipe 41 tapers to the screw 42 towards a taper angle A. to build. In the present exemplary embodiment, the taper angle is A. about 4 °, however, the desired effect of the present invention can be achieved in an angle range of 1 ° to 10 °. In addition, the taper angle begins in the present exemplary embodiment A. of the screw pipe 41 not from the screw 42 screwed end, but the screw tube 41 tapers from the positioning section 413 towards its middle section. As long as the one between the one with the screw 42 screwed end and the screw head 411 intended wall of the screw pipe 41 a taper angle A. the desired effect of the present invention can be obtained. The screw pipe 41 has an internal screw hole 415 on. Part of the pipe wall of the threaded pipe 41 stands with the bicycle handlebar 200 in contact. One end of the screw 42 has a screw head 421 whose diameter is larger than the outside diameter of the screw 42 is on, with the screw head 421 with a flange 422 the one with the second through hole 35 of the second clamping section 33 can be combined, is provided, the outer diameter of the flange 422 smaller than the outside diameter of the screw head 421 is to a second pressing portion 423 to define, the second clamping portion 33 of the clamping ring 30th by the second pressing section 423 is pressed.

It is now on the 4th to 6th , 7A and 7B Referenced. With the above structure, when assembling, the clamping portion 20th with the clamping ring 30th combined by the lead 21st into the delimitation recess 36 of the clamping ring 30th is introduced. The arcuate curved surface of the clamping section 20th is on the arcuate surface 12 of the combination section 11 of the seat body 10 matched to the handlebars together 200 to cover. Then the screw pipe 41 first through the first through hole 34 of the first clamping section 32 of the clamping ring 30th into the combination hole 13 of the seat body 10 inserted, the polygonal positioning section 413 of the screw pipe 41 on the limiting recess 131 of the seat body 10 is tuned to the rotation of the screw tube 41 to limit. The first clamping section 32 of the clamping ring 30th is through the first pressing section 414 of the screw pipe 41 then the screw is pressed 42 into the second through hole 35 of the second clamping section 33 plugged in to the screw 42 into the inner screw hole 415 of the screw pipe 41 screw in, the second clamping portion 33 of the clamping ring 30th by the second pressing section 423 the screw 42 is pressed. Because the wall of the screw pipe 41 has a taper, the wall of the screw tube 41 flared outward when the screw 42 gradually into the inner screw hole 415 of the screw pipe 41 is screwed in (cf. 7B) , making the wall of the threaded pipe 41 tight against the bicycle handlebar 200 is pressed, the arcuate surface 12 of the seat body 10 also the expansion force of the wall of the screw pipe 41 is exposed and thus the handlebars 200 tightly encompassed. In that the clamping section 20th from the clamping ring 30th is included, the elastic tensioning portion 20th the bicycle handlebar 200 grasp tightly so that the brake lever 100 on the bicycle handlebar 200 can be attached.

The clamping section 20th is used to grip the bicycle handlebar 200 through the clamping ring 30th covered, the clamping section 20th is made of elastic rubber / plastic with an excellent shock absorbing function, so that when the bicycle is running on a rough road and is thereby subjected to vibration, by the tensioning portion fulfilling the shock absorbing function 20th can prevent the screws 42 due to vibrations from the threaded pipe 41 solve, thus, the problem of loosening the brake lever 100 effectively solve.

The key point of the present invention is that the pipe wall of the threaded pipe 41 has a taper. If the screw 42 gradually into the inner screw hole 415 of the screw pipe 41 is screwed in, it is achieved that the pipe wall of the screw pipe 41 is expanded outwards, causing the bicycle handlebar 200 firmly pressed and through the expanded arcuate surface 12 of the seat body 10 is tightly encompassed, furthermore the screw 42 through the screw pipe 41 can be held tightly to prevent the screw from moving 42 due to vibrations from the threaded pipe 41 solves, eliminating the problem of loosening, sliding and falling off of the bicycle brake handle 100 is completely avoided.

In summary, it can be said that compared to in the 1 and 2 As shown in the prior art, the problem of loosening bolts caused by vibration and the problem of loosening and falling off the bicycle handlebar can be effectively solved by the present invention. The present invention has a high level of practicality. After reviewing the reports and the market, no identical or similar products were found on the market prior to filing. The invention is therefore a novelty and thus meets the requirements for an application for a utility model. The registration is made according to the law.

The above description represents only a preferred exemplary embodiment of the invention and is not intended to restrict the claims. All equivalent changes and modifications that can be made according to the description and drawings of the invention by one skilled in the art are included within the scope of the present invention. The scope of the invention is determined by the appended claims.
