Definitions

  • the present invention relates to a guide protector for a striatum that encloses one or more striatum therein and protects and guides the striatum.
  • Striatum for example, power cables for boarding OA equipment and electrical appliances indoors, wire harnesses in automobiles and other mechanisms, signal cables for indoor and outdoor communication networks, optical fibers, and even gases and liquids (Ie, in the description above and below, the term “striated body” includes the above-mentioned various hollow or solid and freely bendable tubes) (Used as a broad term)) to protect or guide the striatum, or to bundle multiple striata, to cause incorrect wiring, disconnection of the connector, disconnection, noise contamination, etc.
  • Various guide protectors or bundling devices for the striatum have been proposed for preventing blemishes, improving aesthetics, or carrying portable packaging (Japanese Utility Model Laid-Open No.
  • an object of the present invention is to make it possible to easily bundle and remove the striatum. It is an object of the present invention to provide a guide protector for a striatum that can easily cope with various wiring patterns and is suitable for various uses. Disclosure of the invention
  • a guide protector for a striatum comprises: an inner tubular element accommodating the striatum therein; and an outer tubular element accommodating the inner striatum together with the striatum therein.
  • the inner and outer tubular elements are:
  • Each slit has a continuous length.
  • the slit is made of a material that allows the width of the slit to be freely expanded and contracted.
  • the slit of the inner tubular element is covered with the outer tubular element in a state where the inner and outer duplex parts are combined.
  • the inner and outer tubular elements have the same or similar cross-sectional shapes, it is easy to design a mold for resin molding, for example.
  • a linear body such as a cable for OA equipment having relatively large connectors at both ends can be stored through the slit, so that it can be easily stored in the guide protector in a transparent state.
  • the bundled filaments can be easily removed simply by pulling apart the inner and outer tubular elements.
  • each tubular element is covered with the outer tubular element to combine the two, there is no need to form a precise and strong male and female structure on the tube wall of the tubular element. And the entire tubular element can be soft. Furthermore, since it is only necessary to secure the necessary strength as a guide protector by combining both tubular elements inside and outside, the wall thickness of each tubular element is approximately one half of the thickness required by design (this is (It varies slightly depending on how much the slit width is set), making cutting easier.
  • the section of the guide protector or the section J of the tubular element means a section orthogonal to the longitudinal axis unless otherwise specified.
  • the term" slit I means a very narrow gap. It does not mean only having the gap width, but also includes the gap width from half or less of the entire circumference of the tube wall to the state where the gap width is 0 when viewed from the cross section of the tubular element.
  • the “tube” mentioned above is not particularly limited with respect to the cross-sectional shape orthogonal to the longitudinal direction.
  • the cross-sectional shape of the tube may be a circular shape, a polygonal shape, a combined shape of an arc and a straight line, or an elliptical shape.
  • the guide protector When the guide protector has a circular shape, the flexibility in the longitudinal direction of the guide protector is easily uniform in all directions, and the attachment and detachment of the inner and outer tubular elements is facilitated. In the case of a polygonal shape or a combination of arcs and straight lines, there is a flat part on the tube wall, so the guide protector can be easily fixed along with the floor, wall, desk edge, etc., for example, with double-sided tape, and an ellipse. The shape is advantageous when the guide protector is crawled in a narrow gap, and it is easy to bend in the minor axis direction of the ellipse.
  • a projection or a ridge located between the slits of the other tubular element when combined with each other is provided. This regulates the relative twist position of the inner and outer tubular elements. It is particularly desirable to provide such projections or ridges when the cross-sectional shape of the tube is circular. Furthermore, if the tubular element has a bellows shape, it can be easily bent in the longitudinal direction while securing a certain degree of rigidity in the radial direction of the tubular element, and the relative position of the inner and outer tubular elements in the longitudinal direction can be shifted. It is also useful for prevention.
  • the above-mentioned inner and outer tubular elements may not only be combined in a pair inside and outside, but may be provided in a plural number to obtain a predetermined length.
  • the inner tubular elements and the outer tubular elements are provided with a little space between them for taking out the striatum, a large number of branch lines extend from a trunk line such as a digging step wiring. It is suitable for wiring patterns that are used.
  • a part of the inner tubular element and / or the outer tubular element may have an intersecting portion that branches and assembles in a plane, that is, in the same plane, such as a ⁇ shape, a ⁇ shape, and an X shape, Having a three-dimensional cross-section that branches and gathers in a three-dimensional space can further enhance the flexibility of the wiring pattern.
