Embodiment 1

[0040] figure 1 and Figure 4 The structure of the cushioning member of this embodiment is shown. Reference numeral 1 shown in the figure denotes a cushioning member. The cushioning member 1 includes a cylindrical foam 2 composed of polyurethane foam, and a cutout 3 constituted by a helical cutting line appearing on the cross section of the cylindrical foam 2 . Such as figure 1 As shown, the incision 3 (or cutting line) extends from the opening 4 on the outer peripheral surface of the foam 2 so as to reach the opening 6 on the inner peripheral surface of the foam 2, that is, to reach the central part of the foam 2 and to extend along the foam 2. The axially extending through hole 5. Meanwhile, the incision 3 (or cutting line) includes a straight cutting line portion 3a and a curved cutting line portion 3b.

[0041] The cushioning member 1 is processed as follows. Specifically, utilize Boimel processing machine (manufactured by BUMER company, model is OFS-222CNC), from...

Embodiment 2

[0045] figure 2 The structure of the cushioning member of this embodiment is shown. Reference numeral 11 shown in the drawings denotes a cushioning member. The cushioning member 11 includes a cylindrical foam 12 composed of urethane foam, and a cutout 13 constituted by a cutting line appearing on the cross section of the cylindrical foam 12 . Such as figure 2 As shown, the incision 13 (cutting line) extends from the opening 14 on the outer peripheral surface of the foam 12 to the opening 16 on the inner peripheral surface of the foam 12, that is, to the through hole 15 formed along the axial extension of the foam 12. . The cutout 13 (cutting line) is constituted by a plurality of linear cutout (cutting line) portions 13a, 13b, 13c, 13d, 13e, 13f, and 13g.

[0046] The cushioning member 11 of Embodiment 2 produces an effect similar to that produced by the cushioning member 1 in Embodiment 1. As shown in FIG.

Embodiment 3

[0048] image 3 The structure of the cushioning member of this embodiment is shown in . Reference numeral 21 shown in the drawings denotes a cushioning member. The cushioning member 21 includes a cylindrical foam 22 composed of urethane foam, and a cut 23 formed by a cutting line appearing on the cross section of the cylindrical foam 22 . Such as image 3 As shown, the incision 23 (cutting line) extends from the opening 24 on the outer peripheral surface of the foam 22 so as to reach the opening 26 on the inner peripheral surface of the foam 22, that is, to reach the through hole formed along the axial extension of the foam 22. 25. The cutout 23 (cutting line) is constituted by a plurality of linear cutout (cutting line) portions 23a, 23b and the like.

[0049] The cushioning member 21 of Embodiment 3 produces an effect similar to that produced by the cushioning member 1 of Embodiment 1. As shown in FIG.

Abstract

The invention discloses a covering member comprising a cylindrical foam or a columnar foam including a cut consisting of a slit line which extends from the outer circumferential surface of the foam to reach a through-hole of the foam, wherein the slit line joining the open portion formed by the cut on the outer circumferential surface of the foam to the open portion formed by the cut on the inner circumferential surface of the foam is nonlinear in respect of the cross section of the covering member in a direction perpendicular to the axial direction of the foam.

Description

technical field [0001] The present invention relates to a covering member used as a cushioning member, a heat insulating member or a protective member, and a manufacturing method thereof. More particularly, the present invention relates to a covering member for preventing cables used in parts such as a hood, door locks, fuel filler or damper switch of, for example, a car from coming into contact with the body of the car when subjected to vibrations. Cushioning components that produce strange sounds or noises. The covering member of the present invention is also used as a heat insulating member or a protective member of various daily life pipes, equipment pipes and support rods. Background technique [0002] When it comes to common vehicles such as automobiles, cables are widely used on hoods, door locks, fuel filler and shock absorber switches. As a method to prevent the generation of strange sounds or noises, cylindrical buffer members are used in the cables. In addition...
