  Usually, in order to fix a protector to the site | part to which a cylindrical body is protected, a protector is fixed to a cylindrical body with an adhesive agent. Therefore, an adhesive is required. Furthermore, since it is necessary to soak the adhesive applied from the outside of the protector to the inside of the protector, it takes time. It also takes time to dry the adhesive. For this reason, the workability of the bonding work is poor.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and its purpose is to protect a protector, a composite cylindrical body, a control cable, a vehicle hose, and a protector, which do not require separate application of an adhesive and have good workability.

The protector includes a protective resin fiber that mainly constitutes the protector, and a welding resin fiber that is made of a fiber type different from the protective resin fiber and that can be welded to an object to be protected.

  According to the protector of the present invention, the object to be protected and the resin fiber to be welded can be welded, for example, by ultrasonic welding. Since the welding resin fiber and the protective resin fiber are knitted, the welding resin fiber can be held on the protective resin fiber. Therefore, a protector can be fixed to a protection target object by hold | maintaining the welding resin fiber welded to the protection target object to the protection resin fiber. Therefore, it is not necessary to separately apply an adhesive for fixing the protector to the object to be protected. Furthermore, it is not necessary to soak the adhesive applied from the outside of the protector into the inside of the protector. Also, no time is required for drying the adhesive. Therefore, the workability of the bonding work can be improved.

(Embodiment 1)
First, the structure of the protector according to Embodiment 1 of the present invention will be described.

  With reference to FIG. 1, the protector 1 is for protecting a protection object 4. The protector 1 is configured by weaving resin fibers. The resin fiber may be formed in a thread shape. The protector 1 may be knitted by bundling a plurality of resin fibers. Since the protector 1 is configured by weaving resin fibers, it can be easily deformed in accordance with the shape of the protection object 4. That is, the protector 1 has flexibility and softness. The protector 1 has a cylindrical shape. The protector 1 is configured to be able to insert the protection object 4 on the inner peripheral side. For this reason, the protection target object 4 can be protected by covering the outer surface of the protection target object 4.

  The resin fiber constituting the protector 1 has a plurality of fiber types. The protector 1 mainly has protective resin fibers 2 and welding resin fibers 3. The protective resin fiber 2 mainly constitutes the protector 1. Here, “mainly configured” means that the protector 1 functions mainly as a protector, and does not necessarily include a large amount. The protective resin fiber 2 may be, for example, a nylon fiber. The material of the protective resin fiber 2 may be polypropylene (PP), polyethylene (PE), vinyl chloride, polyethylene terephthalate (PET), or the like.

  The welding resin fiber 3 is made of a fiber type different from the protective resin fiber 2. The welding resin fiber 3 is configured to be weldable to the protection object 4. The resin fiber 3 for welding can be welded to the object 4 to be protected, for example, by ultrasonic welding. The welding resin fiber 3 can be fixed to the protection object 4 at the welded portion, and can be held by the protective resin fiber 2 at the non-welded portion. The material of the welding resin fiber 3 may include, for example, polypropylene.

  The protective resin fiber 2 and the welding resin fiber 3 are knitted together. Since the protective resin fiber 2 is knitted into the welding resin fiber 3, the welding resin fiber 3 can be easily held on the protective resin fiber 2. The resin fibers 3 to be welded to the protective resin fibers 2 may be knitted at regular intervals in the longitudinal direction of the protector 1. It should be noted that the equal intervals need only be substantially the same except for manufacturing errors. Furthermore, the resin fiber 3 to be welded to the protective resin fiber 2 may be knitted spirally in the longitudinal direction of the protector 1. The welding resin fibers 3 may be knitted in, for example, two rows in the protective resin fibers 2.

  The ratio of the protective resin fiber 2 may be larger than the ratio of the welding resin fiber 3. In the protector 1 shown in FIG. 1, the protective resin fiber 2 occupies most of the volume of the protector 1. That is, the amount of the protective resin fiber 2 is significantly larger than the amount of the welding resin fiber 3. For this reason, the outer surface of the protection target object 4 can be effectively protected by the protective resin fiber 2.

  Thus, conventionally, the sleeve is secured to the outer surface of the jacket with an adhesive and tape. Adhesives and tapes can be effective in preventing relative movement between the sleeve and the jacket, but are expensive. For example, adhesives can be expensive for subsequent products, can be cumbersome to apply, and can break in thermally difficult environments such as high heat. Similarly, the use of tape to secure the sleeve to the jacket requires costs for subsequent products and, in addition, can be inefficient and expensive to apply.

  Some attempts have been made to ultrasonically weld known sleeves to jackets, but these efforts have been largely unsuccessful. This unsuccess can result from the different materials of the sleeve and jacket being welded together. Thus, conventionally, adhesives and tapes have been employed to secure the sleeve to the jacket, although there are drawbacks such as those described above.

  Next, the structure and manufacturing method of the protector and composite cylindrical body of Embodiment 4 of this invention are demonstrated.

  With reference to FIG. 10 and FIG. 11, the protector 1 is a cylindrical fabric sleeve. The protector 1 has a plurality of thread-like resin fibers (yarns) that are knitted together by a knitting process to form a wall (tubular wall) 51. The wall 51 is seamless and is continuous in the circumferential direction. The protector 1 has an outer surface 54 and an inner surface 55 that define a cavity 53 extending axially along the central longitudinal axis 50 between both ends 52 of the protector 1. The cavity 53 is dimensioned to accommodate an elongate member, for example represented as a wire harness, whose outer surface 54 is bundled by a jacket 56 (outer polypropylene jacket) formed of polypropylene. After the outer polypropylene jacket 56 is installed through the cavity 53, one or more welded joints 57 cause the inner surface 55 of the wall 51 of the protector 1 to resist relative movement with the outer polypropylene jacket 56. Fixed.

  The wall 51 can be configured with any suitable length and diameter and is knitted with the desired pattern for the intended application. Thus, the wall 51 can be configured with various structural properties and structures. The wall 51 is knitted to include a first yarn filament 58 of polyethylene terephthalate (PET), a second yarn filament 59 of nylon, and a third yarn filament 60 of polypropylene (PP).

  As a preferred embodiment, although not limited as an example, the protector 1 is configured using a 48-placing string machine. Two ends of the first PET yarn 58 are fed for each bobbin. One end of the nylon second yarn 59 is fed per bobbin and two ends of the PP third yarn 60 are fed per bobbin. Forty-two PET and nylon bobbins and six PP bobbins are used. The six PP bobbins are configured in a state in which two bobbins are adjacent to each other and made uniform in parallel. Thus, the four PP filaments are knitted directly adjacent to each other, thereby forming a band with an increased width of the four knitted PP filaments. PET is supplied as a monofilament having a diameter of about 0.25 mm. Nylon is supplied as a monofilament having a diameter of about 0.38 mm. PP is supplied as a monofilament having a diameter of about 0.25 mm. To obtain the desired physical structure, the weaving pattern of the first, second and third yarns 58, 59, 60 can be altered.

  After the protector 1 is formed, the outer polypropylene jacket 56 and the wires bundled thereby are installed through the cavity 53 of the protector 1. The third yarn 60 of PP is then welded to the outer surface of the outer polypropylene jacket 56 by one or more welded joints 57, such as by ultrasonic welding. Thereby, the composite cylindrical body 10 is manufactured. Since the materials PP welded to each other are the same, the formed chemically bonded welded joint portion 57 is strong and highly reliable. Therefore, the protector 1 is securely fixed to the outer polypropylene jacket 56 so as to withstand the fracture of the welded joint portion 57 during assembly and use. Therefore, any misalignment and potential wear due to relative movement between the protector 1 and the outer polypropylene jacket 56 is prevented.

  With reference to FIG. 12, protector 1 configured according to still another aspect of the present invention will be described. The protector 1 is composed of the same first, second and third yarn filaments 158, 159, 160, but the weaving pattern is different from that described above and illustrated in FIGS.

  In particular, the third yarn filament 160 of PP is not knitted to extend helically around the wall 151 with the first and second yarn filaments 158, 159, but rather to the longitudinal central axis 150 of the protector 1. In parallel or substantially parallel to the length of the protector 1 so as to extend in the shape of warp. Accordingly, bundles of third yarn filaments 160 are formed in a circumferentially spaced relationship, and the number of PP third yarn filament 160 ends per bundle can be supplied as desired. it can. With the third yarn filament 160 of PP extending parallel or nearly parallel to the axis 150, the weld joint 157 has a generally rectangular shape extending longitudinally along the length of the protector 1. Thus, the weld patch or weld joint 157 with increased dimensions can be easily formed between the third yarn 160 and the outer polypropylene jacket 156.

  It should be appreciated that the protector 1 is suitable for use in a variety of applications regardless of the dimensions and length required. For example, it can be used in automotive, marine, industrial, aviation, or aerospace applications, or any other application where a protective sleeve is desired to protect adjacent components against thermal radiation.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The present invention relates to a protector, a composite cylindrical body, a control cable, a vehicle hose, a manufacturing method of a protector, and a manufacturing method of a composite cylindrical body, which are formed by weaving resin fibers to protect a protection object. Can be applied particularly advantageously.
