The curve and the position of the holder can be adjusted easily.

Description

Car wire

The present invention relates to a vehicle wire, which is a wire of a bicycle or the like.

The conventional bicycle brake device can refer to the descriptions of the TWM248722 and TWM353151 patent documents, and is connected between the brake handle and the brake clamp device by the brake line, and drives the brake line when the user presses the brake handle, and further pulls the brake clamp with the brake line. Swinging, pinching a particular part of the rim or wheel set creates friction, providing the braking force needed to slow the vehicle.

In order to avoid the abnormal winding of the brake line and affect the use function of the brake line and the brake clamp, the curved line can be used to guide the brake line for the user to adjust the brake line to an appropriate position.

The brake line bend in the aforementioned document is a tubular spiral for the user to adjust the bending angle. However, if only a single layer of spiral is used, the position and angle cannot be fixed after the user bends, and the double spiral is bent. Although it can maintain the adjusted angle afterwards, the two spirals are easy to slide between each other, and it is easy to change the position and angle after being slightly pulled or pulled by a slight external force, and often there is a situation where the position desired by the user is removed.

In addition, double-layer spiral bends require the use of higher hardness snails in the outer spiral. Rotating wire, and possibly accidentally pushing the inner spiral or deforming the inner spiral when winding the outer spiral on the inner spiral, is prone to production problems and has a high technical threshold.

In this regard, the primary object of the present invention is to relieve or at least mitigate the above-mentioned problems that may be encountered.

In order to achieve the above object, the present invention provides a wire for a vehicle for use in a bicycle or the like, which can be bent and adjusted in position and angle of the wire.

The vehicular wire includes a first wire and a second wire, the first wire and the second wire are wound together into a tubular shape to surround a tubular space therein, and the second wire is located in the first wire due to winding Around the gap formed, the second wire has a wedge-shaped cross section, and the tip end of the wedge-shaped section points to a gap formed by the winding of the first wire.

Wherein the second wire may surround the periphery of the first wire such that the first wire is located between the second wire and the tubular space; the wedge-shaped section of the second wire may be a triangle, or two adjacent ends of the wedge-shaped section a curved line in the side; the first wire may have a hardness greater than the second wire; the first wire and the second wire may be spirally wound, such that the first wire and the second wire are both Tubular spiral.

Therefore, the vehicular wire provided by the invention can be bent by the user to adjust the angle arbitrarily, the first wire and the second wire can be mutually abutted, and the second wire has a wedge-shaped cross section, and the first wire and the second wire are made. It is not easy to slide freely, but provides better positioning.

Secondly, since the second wire can be used to offset the first wire by the wedge-shaped cross-section, the second wire does not need to be made of a material with higher hardness, which can avoid the problems that may be encountered in winding the high-hardness wire on the surface of the low-hardness wire, and reduce the technology at the time of production. threshold.

In addition, since the second wire no longer needs to use a high hardness material, it can be changed to the first A wire is made of a harder material, which avoids or reduces the wear caused by the wire pulling movement, improves the service life, or allows the manufacturer to further reduce the thickness of the wire for the vehicle, save material costs and at the same time reduce the weight of the product.

Referring to FIG. 1 , the embodiment provides a vehicular wire 1 for mounting in a brake device and further mounted in a bicycle or the like. The brake device includes a brake wire 2 and a brake clamp 3 that is pulled by the brake wire. The brake wire 2 can be connected to the brake handle, and is driven by the brake handle when the user presses the brake handle to further drive the brake clamp 3 to swing, so that the brake clamp 3 clamps a specific part of the wheel or the wheel set to generate Rubbing to get the use of the brakes. The vehicle wire 1 is sleeved on a part of the brake wire 2, one end abuts against the brake clamp 3, and the other end is bent by the user to adjust the position and angle of the brake wire. It should be noted that the wire 1 for a vehicle of the present invention can also be used in conjunction with a shifting wire or the like.

Referring to FIG. 2 and FIG. 3, the vehicular wire includes a first wire 11 and a second wire 12, and the first wire 11 and the second wire 12 are wound together into a tubular shape to surround a tubular space 13 therein. The common winding is that the first wire 11 and the second wire 12 are wound together in terms of the structure of the first wire and the second wire, and is not limited to the simultaneous production of the first wire and the second wire at the time of production. Winding molding. The second wire 12 is located around the gap formed by the winding of the first wire 11 . Specifically, the first wire 11 and the second wire 12 can be spirally wound to form a similar double wire. Spiral three-dimensional structure. In this embodiment, the second wire 12 is located at the outer periphery of the first wire 11 , that is, from the outer side against the adjacent two turns of the spiral first wire 11 , so that the first wire 11 is located at the second wire 12 and the tubular Between the spaces 13, however, in other possible embodiments of the present invention, the second wire is disposed on the inner side of the first wire such that the second wire is located between the first wire and the tubular space and abuts from the inner side A wire is also indispensable.

The second wire 12 has a wedge-shaped cross section as shown in FIG. The cross-sectional shape of the first wire is not limited, but the first wire is preferably a circular cross section, and the cross-sectional shape having a smooth inner surface after being wound into a tubular shape can be used without considering the consideration of production and usability. The wedge shape refers to a pattern having a tip end, so that an object having a wedge-shaped cross-section can be used to displace other articles by the surface on which the two adjacent sides of the tip are located, and is easily inserted into the slit or the narrow opening. Based on the above, the tip end 121 of the wedge-shaped section of the second wire 12 may be a sharp end point as shown in FIG. 3, and the two sides of the wedge-shaped section may be concave inward in the production based on cost, weight or production considerations. And the formation of the tip, does not affect its function. Specifically, the wedge-shaped cross section of the second wire 12 has two opposite sides 122, 123 of the tip end 121 and the tip end, and the two adjacent sides 122, 123 are concave curves in a wedge-shaped cross section, in detail, may be An arc line, an elliptical arc, a parabola or a hyperbola, the ends of the two adjacent sides 122, 123 are connected by a straight line 124, so that the vehicle wire has a smooth Overall appearance.
