Description

Clamping device

The invention mainly discloses a clamping device, in particular to a clamping device for fixing a bicycle brake grip.

Referring to the "OPERATING DEVICE" patent of U.S. Patent No. 4,188,834, which discloses a brake grip device having a bracket, the bracket is provided with a through hole for sleeved on the handle of the bicycle, one side of the bracket Further opening is provided with an opening communicating with the through hole, the bracket has a screw member, and the screw member is disposed at the opening and used to adjust the gap of the opening to change the inner diameter of the through hole to thereby make the brake handle The device can be firmly placed on the handle of the bicycle. However, since the bracket is integrally formed, the inner diameter of the through hole is limited in amplitude, and the grip sleeve at one end of the bicycle handle is first removed during installation, and the brake grip device is inserted into the end of the bicycle handle. Then, the previously removed grip set is set back to the end of the bicycle handle, so the entire assembly process is rather cumbersome and complicated. In addition, the opening is located on one side of the bracket, and the brake gripping device is thus defined to be dedicated to one side of the bicycle handle. In other words, the right brake grip device can only be placed on the right side of the bicycle handle and vice versa. Brake handle devices on different sides are not mutually versatile with one another, thus increasing manufacturing costs.

In the "CLUTCH CABLE ADJUSTING MECHANISM" patent of U.S. Patent No. 5,966,993, it discloses a brake line adjusting mechanism comprising a support body, a side cover coupled to the support body, and two sets of the side cover and the support body. The screw member defines a sleeve hole between the side cover and the support body for arranging the brake line adjusting mechanism on the bicycle handle. The support body is provided with two screw holes near the side cover, and the side cover is provided with two through holes respectively corresponding to the screw holes, and the through holes and the screw holes are respectively passed through the screw member to stabilize the side cover The ground is coupled to the support body. Although the design does not need to disassemble the grip of the bicycle handle, the side cover and the support body can be assembled. However, the user needs to hold the support body, the side cover and the screw in one hand during the installation process, and then use the other hand to The screw is locked and the installation process is quite inconvenient. For the above problems, there is a need for improvement.

In view of the above-described deficiencies of the conventional structures, the inventors have invented a clamping device that overcomes all of the disadvantages of the above-described conventional structures.

The clamping device of the present invention is expected to provide a clamping device that facilitates assembly and reduces manufacturing costs.

The primary object of the present invention is that each of the clips has the same outer shape, so that the clamping device can be assembled at both ends of the bicycle handle.

A secondary object of the present invention is that when the clamp is in the open position, the assembly of the two clamps is remote from each other to facilitate assembly of the clamps to the handle of the bicycle.

Yet another object of the present invention is that since the first axis is parallel to the third axis and the first axis is perpendicular to the second axis, the clips can be tightly assembled to the handle of the bicycle.

A further object of the present invention is that the inclined portion can prevent the clamp from interfering with the base during the pivoting process and increase the pivoting angle of the clamp.

Other objects, advantages and novel features of the invention will be apparent from the description and appended claims.

The present invention is described with respect to the preferred embodiments and the accompanying drawings.

Referring to Figures 1 to 3, a first embodiment of the clamping device 1 of the present invention is shown. The clamping device 1 includes a base 20, a clamping set 30 pivoted to the base 20, and a fixed set 40 assembled to the clamping set 30. The base 20 is provided with a brake grip (not numbered).

The base 20 includes a support portion 21 having an abutment surface 211 away from one end of the brake grip. The abutting surface 211 is used to abut the handle of the bicycle. Referring to FIG. 4 and FIG. 5 simultaneously, in the embodiment, the abutting surface 211 is a curved curved surface curved along an axis c. The support portion 21 has a first surface 21a, a second surface 21b remote from the first surface 21a, and two side surfaces 21c extending from both ends of the first surface 21a to both ends of the second surface 21b. In this embodiment, the first surface 21a and the second surface 21b respectively have an inclined portion 212 through which the tangent of the inclined portion 212 passes. The support portion 21 has a pivot hole 214 that extends from one of the side faces 21c to the other side face 21c. The side edges 21c of the support portion 21 are respectively formed with a groove portion 213 which communicates with both ends of the pivot hole 214.

The clamping set 30 includes two clamps 31 and a pin 32. The pin 32 is used to connect the clamp 31 and the support portion 21 of the base 20. In the present embodiment, the clips 31 have the same outer shape structure. One end of each of the clamps 31 has a connecting portion 311, and the other end of each of the clamps 31 has an assembly portion 312. The connecting portion 311 is for connecting to the base 20 . Each of the connecting portions 311 forms a pivoting arm 313 at a corresponding groove portion 213. Each of the pivoting arms 313 is provided with a through hole 314 corresponding to the pivot hole 214 of the base 20. The pin 32 is disposed through the pivot hole 214 and the through hole 314 , so that the clip 31 is pivoted to the base 20 . The assembly portion 312 is provided with a through hole 315 for receiving the fixed group 40. In the present embodiment, the through hole 314 has a first axis A1 along the longitudinal direction of the through hole 314, and the through hole 315 has a second axis A2 along the longitudinal direction of the through hole 315, and the pivot hole 214 is along The pivot hole 214 has a third axis A3 in the longitudinal direction. The first axis A1 is perpendicular to the second axis A2, and the first axis A1 is parallel to the third axis A3.

Each of the clips 31 further has an abutting top 316 between the connecting portion 311 and the assembly portion 312 for abutting the handle of the bicycle. In the present embodiment, the abutting top 316 has a curved curved surface and has the same bending radius as the abutting surface 211 of the base 20.

The fixing member 40 includes a screw member 41 and a nut 42 extending through the through hole 315 of the clamping group 30 and one end of the screw member 41 abuts against one of the clamping members 31. The nut 42 The nut 42 is sleeved on the other end of the screw 41 and the nut 42 abuts against the other clamp 31. Since the first axis A1 is parallel to the third axis A3 and the first axis A1 is perpendicular to the second axis A2, the clamping member 31 can be tightly assembled to the handle of the bicycle by the fixing group 40.

Referring to Figures 6-8, the clamp 31 of the clamp set 30 can be pivoted between an open position (shown in Figure 6) and a clamped position (shown in Figure 8). When the clamp 31 is in the open position, the assembly portions 312 of the two clamps 31 are away from each other to facilitate the assembly of the clamp 31 to the handle of the bicycle. The inclined portion 212 can prevent the clamp 31 from interfering with the base 20 during the pivoting process and increase the pivoting angle of the clamp 31. When the clamping member 31 is in the clamping position, the assembly portions 312 of the two clamping members 31 are close to each other, and the abutting surface 211 and the abutting top 316 together abut the bicycle handle, and then the fixing group 40 can be used to make the clip. The solid set 30 is firmly placed on the handle of the bicycle.

Referring to Figure 9, the handle of the bicycle has a fourth axis A4 along the longitudinal direction of the handle, the third axis A3 being parallel to the fourth axis A4. Each of the clips 31 has the same outer shape and is symmetrically assembled to the handle of the bicycle. When the clamping device 1 is assembled at a first end of the bicycle handle, one of the clamps 31 (here defined as a first clamp) abuts against the upper surface of the first end of the bicycle handle, and the other clamp 31 (here defined as a second clamp) abuts against the lower surface of the first end of the bicycle handle. When the clamping device 1 is assembled to a second end of the bicycle handle, the second end is away from the first end, the first clamping member abuts the lower surface of the second end of the bicycle handle, and the second clamping member is abutted And an upper surface of the second end of the bicycle handle. The clamping device 1 can be assembled at both ends of the bicycle handle, thereby reducing the manufacturing cost.

Referring to Figures 10 and 11, a second embodiment of the clamping device 1 of the present invention is shown. It is substantially the same as the first embodiment, wherein the support portion 21 has two pivot holes 214a and four groove portions 213a. The pivot holes 214a are parallel to each other and spaced apart by a distance. Two of the groove portions 213a are formed on one of the side faces 21c, and the other two groove portions 213a are formed on the other side face 21c. The four groove portions 213a respectively correspond to and communicate with the pivot hole 214a. Each of the clamping member 31 connecting portions 311 forms two pivoting arms 313a, and each of the pivoting arms 313a is provided with a through hole 314a corresponding to the pivot hole 214a. The clamping group 30 has two pins 32a. The pivoting arms 313a are respectively disposed on the groove portion 213a. The pins 32a are respectively disposed through the through holes 314a of the clamping member 31 and the pivot holes 214a of the base 20. Since the clip 31 has two pivot arms 313a, the clip 31 has more excellent strength and durability.
