Description

  The present invention relates to a cable used for a brake or a transmission of a bicycle or the like, and more particularly, to a cable that adjusts the ratio and combination method of internal shield wires as necessary to obtain optimum flexibility and rigidity.

  Currently, many people use bicycles for exercise, and bicycle parts of various vehicle types such as leisure, sports, and races are constantly being improved and developed. In particular, in recent years, many new structures have been created in the bicycle industry in order to meet the demand of users for transmissions.

In general, a bicycle cable is disposed along a frame between a handle and a brake and between the handle and a transmission. Since all the shield wires in the cable are made of the same material, the rigidity may be too large or too small. If the rigidity of the cable is too great, the bicycle handle may be biased to the left or right side, and it is necessary to attach the cable at a large bending angle in order to accommodate the large rigidity.
If the rigidity of the cable is too small, the lubrication pad in the cable will bend, and when the brake is applied or the speed change operation is performed, if the wire is pulled, the friction coefficient within the predetermined length cannot be maintained, The coefficient of friction may increase. For this reason, there is a risk that it takes time for braking and shifting, and extra tension is required. Thus, in view of the various problems described above, improvements have been demanded for conventional cables.

The object of the present invention is to adjust the ratio of the metal shield wire and the non-metal shield wire in the interior and the method of covering the lubrication pad by combining the metal shield wire and the non-metal shield wire as necessary. The object is to provide a cable that optimizes flexibility and rigidity.
That is, as in the conventional case, if the shield wires in the cable are all made of the same material, the rigidity may be too large or too small. In order to adapt to large rigidity, it is necessary to attach the cable at a large bending angle, but in the present invention, the rigidity can be set appropriately and the deviation of the handle can be eliminated. On the contrary, if the cable stiffness is too small, the lubrication pad in the cable will bend, and when the brake is applied or the speed change operation is performed, when the wire is pulled, the friction coefficient within the specified length is maintained. The friction coefficient may increase. An object of the present invention is to provide a cable that can prevent an increase in the friction coefficient of a wire by appropriately setting rigidity.

  In order to solve the above-described problem, according to the first aspect of the present invention, there is provided a cable including an outer layer, a reinforcing layer, a lining member, a plurality of shield wires, a lubricating pad, and a wire, The lubricating pad is disposed, and the lubricating pad is covered with the plurality of shield wires composed of a metal shield wire and a non-metal shield wire combined with each other, and the plurality of shield wires are covered with the lining member. A cable is provided in which the reinforcing layer made of knitted nylon is arranged on the outer edge of the lining member, and the outer layer made of plastic is arranged on the outer edge of the reinforcing layer.

  Moreover, it is preferable that the said metal shield wire consists of steel, iron, aluminum, a magnesium aluminum alloy, or a titanium alloy.

  The non-metallic shield wire is preferably made of carbon fiber or plastic.

  Moreover, it is preferable that the ratio which the said metal shield wire and the said non-metal shield wire occupy in the said cable can be adjusted as needed.

  Moreover, it is preferable that the system which covers the said lubrication pad by combining the said metal shield wire and the said non-metal shield wire mutually in the said cable can be adjusted as needed.

  The cable of the present invention is a so-called coaxial cable that is arranged so as to be connected to the brake and the transmission along the frame from the handle, and this cable is a so-called coaxial cable that operates the brake and the transmission. It is possible to prevent the handle from being adversely affected and biased to the left or right.

  Also, multiple shielded wires in the cable can be optimized for flexibility and rigidity as needed, so that the lubricating pad in the cable is protected to prevent bending of the lubricating pad, and the brake is applied. When applying or changing speed, even if the wire in the cable is pulled, the coefficient of friction can be kept to a minimum within a predetermined length, and braking or stopping and speeding can be done quickly and reliably. It can be carried out.

It is a perspective view which shows the cable by one Embodiment of this invention. It is sectional drawing which shows the cable by one Embodiment of this invention. It is sectional drawing which shows a state when the metal shield wire and nonmetal shield wire of the cable by one Embodiment of this invention are combined. It is sectional drawing which shows another state when the metal shield wire and nonmetal shield wire of the cable by one Embodiment of this invention are combined.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited thereby.

A cable according to an embodiment of the present invention is a so-called coaxial cable that is arranged so as to be connected to a brake and a transmission along a frame from a handle of a bicycle or the like and operates the brake and the transmission. Description will be given with reference to FIG.
As shown in FIGS. 1 to 4, the cable 20 according to an embodiment of the present invention includes at least an outer layer 30, a reinforcing layer 40, a lining member 50, a plurality of shield wires 60, a lubricating pad 70, and a wire 80. A lubrication pad 70 is disposed on the outer edge of the wire 80. The lubricating pad 70 is covered with a plurality of shield wires 60. The plurality of shield wires 60 include a metal shield wire 61 and a non-metal shield wire 62.

  The metal shield wire 61 is made of steel 611, iron 612, aluminum 613, magnesium aluminum alloy 614, titanium alloy 615, or the like. The non-metallic shield wire 62 is made of carbon fiber 621, plastic 622, and the like. The metal shield wire 61 and the non-metal shield wire 62 are combined with each other so as to cover the lubricating pad 70, so that the flexibility and rigidity of the cable 20 are optimized. The plurality of shield wires 60 are covered with the lining member 50. A reinforcement layer 40 made of knitted nylon is disposed on the outer edge of the lining member 50. An outer layer 30 made of plastic is disposed on the outer edge of the reinforcing layer 40.

  The cable according to the present embodiment is used for a brake or a transmission of a bicycle or the like, and a coaxial wire 80 at the center moves with respect to an outer tube as the outer layer 30 via a lubrication pad 70. Although it is a so-called coaxial cable that is arranged to be connected to the brake and the transmission along the frame and operates the brake and the transmission, the rigidity of the cable 20 can be adjusted.

  That is, the ratio of the metal shield wire 61 and the non-metal shield wire 62 in the cable 20 and the method of covering the lubricating pad 70 by combining the metal shield wire 61 and the non-metal shield wire 62 are adjusted as necessary. Therefore, the rigidity of the cable 20 is not too large or too small, and the handle can be prevented from being adversely affected and biased to the left side or the right side.

  Further, since the plurality of shield wires 60 in the cable 20 can be optimized in flexibility and rigidity as necessary, the lubricating pad 70 in the cable 20 is protected and the lubricating pad is bent. When the brake 80 is applied or the speed change operation is performed, even if the wire 80 in the cable 20 is pulled, the coefficient of friction can be kept to a minimum within a predetermined length, and the brake can be stopped or decelerated. Shifting can be performed quickly and reliably.

  While the preferred embodiments of the present invention have been disclosed above, as may be appreciated by those skilled in the art, they are not intended to limit the invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the claims of the present invention should be construed broadly including such changes and modifications.
