Description

Bicycle guide

The invention relates to a bicycle lead.

A general bicycle wire wiring system includes at least one control wire, and each of the control wires includes a control cable and a rigid outer tube covering the control cable. The control cable is connected to an operator located at the handle portion. When the manipulator is turned, the control cable will move back and forth relative to the rigid outer tube to control the bicycle's actuation mechanism. Such as the wiring system disclosed by TWM280341 and TWM436029.

However, the wires of this kind of bicycle wire wiring system need to pass the internal control cable through the rigid outer tube in the production, which makes the wire difficult to manufacture and costs a lot of cost. In addition, each wire needs to be bent for an additional length Provides a margin for dragging when the handlebar is steered to avoid affecting the braking function during steering, but this will increase costs, confuse wiring, and cause braking delay.

Therefore, it is necessary to provide a novel and improved bicycle wire guide to solve the above problems.

The main object of the present invention is to provide a bicycle lead wire device capable of assembling a guide wire body on a bicycle frame.

In order to achieve the above object, the present invention provides a bicycle guide provided for a shaft tube portion of a bicycle frame. The shaft tube portion includes a pivotable front fork vertical tube, and the bicycle frame is further provided with a cross tube connected to the shaft tube. A handle part and an actuating mechanism, the handle part is provided with a control part, the bicycle wire guide comprises: a lead body provided with at least one restraining channel, the at least one restraining channel is provided for at least one connection between the control part and the The wire body of the actuating mechanism passes through; a contact part is connected to the wire body for being provided on the shaft tube part.

The following only illustrates the possible implementation aspects of the present invention by way of examples, but is not intended to limit the scope of the present invention to be protected, which will be described first.

Please refer to FIGS. 1 to 5, which show a preferred embodiment of the present invention. The bicycle wire guide 1 of the present invention is provided on a shaft tube portion 100 of a bicycle frame. The shaft tube portion 100 includes a pivotable front fork and a vertical portion. Tube 101, the bicycle frame is further provided with a handle portion 102 and an actuating mechanism 103 that are transverse to the shaft tube portion 100, and the handle portion 102 is provided with a control portion 104. The axle tube portion 100 may further include a head tube 105, a front vertical tube 106, and a front bowl set 107. The bicycle wire guide 1 may be disposed on the head tube 105, the front vertical tube 106, or the front bowl set 107.

The bicycle wire guide 1 includes a wire body 10 and a contact portion 20. The wire body 10 is provided with at least one restraining channel 11, and the at least one restraining channel 11 is passed by at least one control line 108 connecting the operation portion 104 and the actuating mechanism 103. The abutting portion 20 is connected to the lead body 10 and is provided on the shaft tube portion 100. The control line 108 may be a brake line or a transmission line, and the actuating mechanism 103 may be a brake or a transmission. Thereby, the guide wire body can be effectively assembled on the frame.

In this embodiment, the wire body 10 is a cylinder, the restraint channel 11 is an axial through hole, and the abutment portion 20 is a sleeve body connected to the outside of the wire body 10, and the sleeve body can have a diameter To deformation. However, the restraint channel can also be a slot that is open on the peripheral surface of the wire body, and the abutment portion 20 can also be directly installed (such as but not limited to hooping or locking) outside the head tube 105.

Preferably, a through hole 12 is provided in the cylinder in another axial direction. The number of the at least one restraint channel 11 is plural, and the plurality of restraint channels 11 are arranged around the through hole 12. The post body is further provided with an outer circumferential groove 13, and the sleeve body is nested in the outer circumferential groove 13. The cylinder further includes a flange 14 protruding from two opposite sides of the outer peripheral groove 13 to block the sleeve. The sleeve protrudes radially from the flange 14 of the cylinder. In other embodiments, the wire body 10 and the abutting portion 20 may be integrally formed into a single component, as long as a structure capable of radial deformation is provided.

The sleeve body is provided with a section groove 21 which is not parallel to an axial direction of the shaft tube portion 100. In detail, the section groove 21 is diagonally cut between the two ends of the sleeve body. The slots 21 may be through slots or blind slots and the number may be one or plural. The sleeve body may not be provided with a slit, for example, the sleeve body is made of flexible material.

Preferably, the diameter of the through hole 12 is larger than the diameter of each of the axial through holes (restraint channels). There is a gap 30 between the sleeve and the cylinder. The sleeve can rotate relative to the cylinder. The sleeve can be set not to rotate relative to the cylinder. For example, when the sleeve body is inserted into the front fork vertical pipe 101, the cutout groove 21 provides a radial compression margin of the sleeve body, which can be applied to the assembly of various pipe diameters. Can provide further deformation space. After the sleeve body is placed in the front fork riser 101, the sleeve body can stabilize the sleeve body so as to contact the pillar body. Of course, if the sleeve body and the pillar system are self-lubricating materials (such as Teflon or the like) ), Can still rotate relatively; or, after the sleeve body is placed in the front fork riser 101, the sleeve body and the cylinder body can still have a gap, and can also rotate relatively.

Preferably, the control line 108 extends along the inside of the handlebar portion 102, and passes through the bicycle guide 1 and extends along the shaft tube portion 100 and the interior of the bicycle tube. The control line 108 is assembled and guided to the structure. The inside is not exposed, beautiful and not easy to be damaged, and the bicycle wire guide 1 is provided on the shaft tube portion 100 (that is, the steering center of the handlebar portion 102), and preferably the cylinder can be rotated relative to the sleeve body. It does not affect the braking function when steering, and the braking is precise and immediate and delayed.

In another preferred embodiment as shown in FIG. 6, the bicycle wire guide 1 a is provided on or directly serves as a head cup 107 a, and the control wire 108 a extends from the outside of the handle portion 102 a through the bicycle wire guide 1 a to enter. This shaft tube portion 100a.
