Description

Cable, cable system with cable, and moving system for moving cable {TOOTHED CABLE, CABLE APPARATUS HAVE TOOTHED CABLE AND MOVE SYSTEM OF MOVE BODY}

The present invention relates to an indwelling cable, a cable device provided with the indwelling cable, and a moving system of a moving object.

Conventionally, the attracting cable is composed of a core cable and a wire wound spirally at a constant pitch around the core cable, and has plasticity, thereby attracting rotational movement of the gear by engaging a gear for moving the attracting cable with the wire. To convert the cable into linear motion. The indwelling cable moves along a guide member that is appropriately curved, and its end portion is connected to a moving object such as a sunroof of a vehicle or a window glass and used as a moving system of the moving object. In order to reduce the sliding sound when the wire surface of the indwelling cable slides with the inner surface of the guide member, a yarn is formed in the groove formed by the core cable and the wire, so that the yarn, not the wire, is moved to the inner surface of the guide member. And sliding are known.

Patent Document 1 discloses an indwelling cable which winds a yarn having elasticity in the radial direction to a groove, protrudes the yarn radially outward from the wire, and slides the yarn with the inner surface of the guide member.

In addition, Patent Document 2 discloses an induction cable provided with an intermediate layer obtained by heating a core cable and a spiral wire, winding a yarn made of a thermoplastic resin into a groove, and melting and fixing the yarn by heat of the core cable and the wire.

In addition, Patent Document 3 discloses an indwelling cable in which a yarn obtained by applying an adhesive to the periphery of the screen and cultivating the yarn into a radial shape is adhesively fixed to the groove.

However, in the attracting cable described in Patent Literature 1, the gear and the yarn for moving the attracting cable are always in contact with each other, so that the yarn gradually wears out and leads to breakage, and the inner surface of the yarn and the guide member does not slide so that the slide sound becomes large. There is.

Moreover, since the indwelling cable of patent document 2 heats to temperature higher than melting | fusing point of a yarn, a pile melts and its length becomes short, and there exists a problem that a slide sound becomes large because the inner surface of a yarn and a guide member does not slide.

In addition, in the attracting cable described in Patent Document 3, if the amount of the adhesive when the yarn is bonded to the core cable is large, the adhesive enters the pile on the guide member side to cure the pile and slide the yarn with the inner surface of the guide member. There is a problem of loudness. On the other hand, when the amount of the adhesive is small, the yarn is peeled off from the groove due to poor adhesion, and the inner surfaces of the yarn and the guide member do not slide, and there is a problem that the slide sound becomes large. In addition, when winding, the file deformed under compression between the core cable and the core cable is deformed to return to its original shape, and the screen is pushed up. By repeating the contact with the yarn, the yarn is finally broken, and the inner surface of the yarn and the guide member does not slide, resulting in a large slide sound.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is possible to reliably slide on the inner surface of the guide member without causing the yarn to be broken to reduce the fluctuation noise, and to groove the yarn while maintaining the flexibility of the yarn without bonding. It is an object to provide a attracting cable that can be supported.

The induction cable of the present invention includes a core cable, a wire wound in a spiral shape at a constant pitch around the core cable, a screen fixed and a pile fixed to the screen, and the sidewall surface formed by the core cable and the wire. A child cable having yarns spirally wound in a groove having a bottom and a bottom, wherein when the yarns are spirally wound in the grooves, the pile is disposed radially outward from the examination so as to contact the side wall surface. And a length protruding to the outside of the groove, wherein a distance from the center of the screen to the bottom surface is smaller than a distance from the center of the screen to the tip of the pile before winding to the groove. It features.

In addition, the induction cable of the present invention includes a core cable, a wire wound spirally at a constant pitch around the core cable, a screen fixed and a file fixed to the screen, and formed by the core cable and the wire. An induction cable having a yarn wound spirally in a groove having a side wall surface and a bottom surface, the process of winding the yarn in the groove under tension and heating the yarn under the tension to soften the screening. It is obtained by the manufacturing method including the process to make and the process of cooling the said screen | substrate which softened.

(1) Since the indwelling cable of the present invention has a length in which the pile protrudes outward of the groove when the yarn is spirally wound around the groove, the yarn can be reliably slid to the inner surface of the guide member, Since the distance from the center to the bottom of the groove is smaller than the distance from the center of the examination before winding to the groove to the tip of the pile, the examination can be reliably supported at a position not touching the gear.

(2) When at least both ends of the yarn are fixed to at least either of the core cable and the wire, the yarn can be reliably supported on the core cable without peeling off the groove.

(3) In addition, the induction cable of the present invention includes a step of winding a yarn in a groove in a state where tension is applied, a step of heating the softening screen in a state where the tension is maintained, and a step of cooling the soft screen. Since it is obtained by the method, the position of examination when winding up can be maintained reliably.

(4) When the yarn is made of a thermoplastic resin and the melting point of the screening is lower than the melting point of the pile, the pile does not melt when the screening is softened, and thus the flexibility of the yarn can be maintained.

It is explanatory drawing which shows the measurement state of a slide sound.

As shown in FIG. 1, the core cable 1 has a core wire 2 which is a straight galvanized steel wire having a diameter of 0.6 to 0.8 mm, and a diameter of 0.4 to 0.6 on the core wire 2. A lower layer (3) wound on 6 mm thick galvanized steel wires and an upper layer (4) wound on the lower layer (3) in a reverse direction from the lower layer (3). On the upper layer 4, the wire 5, which is a galvanized steel wire having a diameter of 1.0 to 1.2 mm, is wound in the same direction as the lower layer 3 at a pitch of 2.4 to 2.6 mm.

The groove 6 formed by the wire 5 and the core cable 1 includes a side wall portion 7, which is an outer surface of the wire 5, and a bottom portion 8, which is an outer surface of the core cable 1. It is comprised by spiral shape, and the yarn 9 mentioned later is wound here.

Yarn 9 is comprised by examination 9a and the pile 9b, as shown in FIG. As the screening 9a, what condensed thermoplastic resin fibers, such as nylon 6, nylon 66, polyester, and cellulose, is used. As the pile 9b, nylon 6, nylon 66, nylon 6. 10, nylon 6. Fibers having a thickness of 25 to 40 µm and a length of 1.5 to 2.0 such as 12 and polyester are used, but are not necessarily limited to this range.

As the manufacturing method of the said yarn 9, the method of apply | coating an adhesive agent to the said examination 9a, and fixing the pile 9b to the said examination 9a radially by electrostatic hair etc. is used. In addition, a known technique such as a method of arranging a file in the direction perpendicular to the examination between the two examinations and vertically interlocking the two examinations together and fixing the file to the examination can be used (see FIG. 5). .

To wind the yarn 9 into the groove 6, first, the feeding device of the yarn 9 is rotated while the core cable and the wire are fixed so as not to rotate, thereby giving tension such that the screening touches the bottom of the groove. While winding The tension of the yarn 9 is changed from the pile placed between the core and the core cable, and as shown in Fig. 3, the distance La from the center of the core to the bottom is wound from the center of the core before the winding. When the wire 5 and the gear 11 are engaged with each other so as to be smaller than the distance Lb (see FIG. 2) to the tip of the pile, as shown in FIG. 4, the tip of the gear 11 is examined 9a. ) Is set so as not to contact. At this time, the examination is in a state where stress is applied in a direction falling from the groove.

Next, if the core cable 1 and the wire 5 are heated to a temperature at which the screening of the yarn softens by high frequency induction heating while maintaining the tension, the screening is softened and the screening is moved from the groove. The stress is removed. At this time, since the screening does not melt, the relationship La <Lb is maintained. If the melting point of the thermoplastic resin used for the pile is set higher than the melting point of the thermoplastic resin used for the screening, the file does not melt during the softening of the screening, and thus the flexibility of the file can be maintained.

Next, when screening is naturally cooled, it hardens | cures, maintaining the shape at the time when a yarn was initially wound in the groove | channel. Thereby, only the stress in the direction falling from the groove | channel which applied to examination is removed, and it becomes possible to reliably support a yarn to a groove | channel in relation of La <Lb.

Finally, the core cable, wire and yarn are cut at once using a cutter so that the continuously produced indwelling cable has a desired length. The yarn of the cut part melts by the frictional heat of the rotary blade of the cutter and the attracting cable generated at this time, and both ends of the yarn in the longitudinal direction are fixed to the core cable and / or the wire.

In the thus-obtained cable obtained, the yarn does not lead to breakage because the screening does not contact the tip of the gear when the wire is engaged with the gear. In addition, since the pile is projected to the outside of the groove, the yarn can reliably slide with the inner surface of the guide member, and the slide sound can be reduced. In addition, since the yarn is not bonded to the core cable with an adhesive, the flexibility of the yarn can be maintained.

The indwelling cable is appropriately bent to a guide member formed of a metal or synthetic resin pipe having an inner diameter larger than the outer diameter of the wire, or a guide having a U-shaped cross section having a width and a height larger than the outer diameter of the wire. Since it is inserted, it can be used as a cable device which moves in the said guide member.

Further, the attracting cable can be used as a moving system for converting the rotational movement of the gear into the linear motion of the moving body by connecting the end portion to a moving body such as a sunroof, window glass, seat, slide door, windscreen of a two-wheeled vehicle, and the like. However, it is not limited to the mobile body.

Next, the attracting cable of this invention is demonstrated with reference to a specific Example and a comparative example.
