Abstract

PROBLEM TO BE SOLVED: To provide a cushioning material being hardly detached from a band main body.SOLUTION: A cushioning material 22 is provided with a cover section 30 being curved such that a center line CL passing a center of a thickness is convex toward a side opposite to a band main body 20 side and is integrally formed with end portion hold sections 31 formed with grooves 36 inserted with end portions 20e of a band main body 20 at both end portions of a cover section 30. The cover section 30 curved is corrected to be linear by inserting the end portions 20e of the band main body 20 into the grooves 36 and mounting the cushioning material 22 onto the band main body 20. Internal stress for causing the cover section 30 to return to an original shape curved is generated in the cover section 30 corrected to be linear, and rotational force C in a direction opposite to a direction where the band main body 20 is turned up is applied to both the end portions of the cover section 30. On this account, the cushioning material 22 is suppressed from having both the end portions turned up and being detached from band main body 20.

Description

  The present invention relates to a cushion material attached to a band for supporting a container, a band with a cushion material, and a container support structure.

  A container support structure for supporting a vehicle container such as a fuel tank on a vehicle body using a band with a cushion material is known (see, for example, Patent Document 1).

Japanese Patent No. 04167056

  The band with a cushion material is composed of a band body and a cushion material. The cushion material is integrally formed at both ends of the cover portion so as to be fitted to both ends of the band body in the width direction, and a cover portion arranged to cover the surface of the band body corresponding to the fuel tank. A pair of grooves including a side wall portion and a turned-up portion are provided, and the both ends of the band body are fitted to the pair of fitting grooves and attached to the band body.

  However, since the cover portion of the cushion material is curved in a convex shape toward the folded portion side, when it is assembled to the band main body, internal stress is generated to return to the original curved shape, and both ends are covered from the folded portion. Rotational force toward the part is added. Since the direction in which the rotational force acts is a direction in which the fitting groove is detached from the band, it is necessary to take some measures so that the fitting groove does not come off from the band body. In order to prevent the fitting groove from being detached from the band main body, for example, it is necessary to take measures such as bonding the band main body and the cushion material with an adhesive, and the work becomes complicated.

  In view of the above facts, an object of the present invention is to provide a cushion material that does not easily come off the band body, a band with a cushion material provided with the cushion material, and a container support structure in which the container is supported by the band with the cushion material.

  The cushion material according to claim 1 is formed of an elastic material, is disposed on the container side of a long band body for supporting the container, and is a surface that comes into contact with the container when viewed in the longitudinal direction. A long band-shaped cover portion that is curved so that a center line passing through the center of the back surface that contacts the band main body protrudes toward the container side, and is formed of an elastic material, and at both ends in the width direction of the cover portion. And an end holding portion provided with a groove into which the width direction end of the band main body is inserted.

  The cushion material according to claim 1 is attached to the long band body as follows. Since the cover member and the end holding portion are made of an elastic material, the cushion material can open the groove by elastically deforming the end holding portion. The cushion material can be easily attached to the band body by easily inserting both ends in the width direction of the band body into the grooves at both ends in the width direction of the cover.

  By attaching the cushion material to the band body, the long band-shaped cover that is curved so that the center line passing through the center of the surface that contacts the container and the back surface that contacts the band body protrudes toward the container side is elastically deformed. And straightened. The cover that has been straightened has an internal stress that tends to return to its original curved shape, and this causes a rotational force in the direction opposite to the direction of the band body to act on both ends of the cover. For this reason, the cushion material is prevented from curling at both ends and coming off the band body.

  According to a second aspect of the present invention, in the cushion material according to the first aspect, the cover portion is formed to have a constant thickness in the width direction.

  In the cushion material according to claim 2, since the covering portion is formed to have a constant thickness, when the cushion material is attached to a band body having a constant thickness in which the shape in the width direction is formed in a straight line, it is seen in a cross section in the width direction. The container-side surface is straight in the width direction. For this reason, the whole width direction of a cover part can be stuck to the plane part of a container.

  The band with a cushion material according to claim 3 is a bottom support portion that supports the bottom portion of the container, and an attachment portion that extends from at least one end of the bottom support portion in a direction crossing the bottom support portion and is attached to the vehicle body. And a cushion material according to claim 1 attached to at least the bottom support portion.

  In the band with the cushion material according to claim 3, the band main body is bent between the bottom support portion and the attachment portion, but the cushion material is formed of an elastic material, so it can be easily adapted to the shape of the band main body. Can be transformed into When the cushion material is bent, stress that tends to be deformed toward the container may act on both ends of the cover portion. However, the internal stress that tries to return to the original curved shape is applied to the cushion material. Since it can cancel by acting in the opposite direction with respect to the stress which is going to deform | transform to the side, it can suppress that a cushion material remove | deviates from a band main body.

  According to a fourth aspect of the present invention, the container support structure supports the container by fixing the band body to which the cushion material according to the first or second aspect is attached to the vehicle body.

  According to the container support structure of claim 4, since the container is supported by fixing the band main body to which the cushion material according to claim 1 or 2 is attached to the vehicle body, the container is supported. Can also prevent the cushion material from coming off the band body.

  As described above, according to the cushion material of the first aspect, it is difficult to come off the attached band body.

  According to the cushion material of Claim 2, a cover part can be closely_contact | adhered to the plane part of a container, and the retainability of a container can be improved.

  According to the band with the cushion material according to the third aspect, since the cushion material is unlikely to be detached from the band body, it is not necessary to bond the cushion material so as not to be detached from the band body.

  According to the container support structure of claim 4, since the cushion material can be prevented from coming off the band body, the band body is prevented from directly contacting the container and the cushion material is always kept in contact with the container. It becomes possible to do.
