  • Patent number: 10741853
    Abstract: The purpose of the present invention is to provide a structure which is configured so that the handling workability of a rubber-only gasket is improved and, even when a gasket body and a carrier film adhere to each other, the carrier film is easily detached from the gasket body. To achieve the object, a rubber-only gasket body and a carrier film containing a resin film detachably holding the gasket body are combined and a gasket holding portion containing a three-dimensional shape deformed along an outer shape of the gasket body is provided in a portion overlapping with the gasket body on the plane in the carrier film. The gasket holding portion containing the three-dimensional shape has a stepped shape in which one side surface of the gasket body is not held and only the other side surface and the lower surface of the gasket body are held.

  • Patent number: 10626993
    Abstract: The present invention improves the handling properties of a rubber-only gasket and the affixability thereof to an attachment position. To this end, the provided gasket is: obtained by combining a gasket body of the rubber-only type, and a carrier sheet that comprises a resin film and holds the gasket body in an un-adhered state; and characterized in that the gasket body is provided with an adhesive section or bonding section for adhering or bonding the gasket body to an attachment position when attaching the gasket body to the attachment position. The adhesive section or bonding section is prepared by providing the lateral surface of the gasket body with a projecting section, and coating the surface of the projecting section with an adhesive or bonding agent. The gasket body is to be used as a gasket for a fuel cell to be incorporated into a fuel cell stack.

  • Patent number: 10511034
    Abstract: The invention provides gasket for a fuel battery provided in a fuel battery cell in which an intermediate part including an MEA is interposed between a pair of separators, and structured such that each of a gasket main body retained to one separator of the pair of separators and a gasket main body retained to the other separator comes into contact with the intermediate part at positions where they overlap planarly, wherein bank portions for fixed size stop according to a gasket thickness are integrally formed in both sides or one side in a width direction of both the gasket main bodies. The bank portions for fixed size stop are preferably supported by convex portions which are provided in the separators. Therefore, it is possible to inhibit gasket main bodies from being compressed beyond supposition in the case that contact portions of the gasket main bodies are compressed.

  • Patent number: 10465798
    Abstract: The invention provides a gasket which improves a handling workability of a rubber only type gasket. The gasket of the invention is constructed by a combination of a rubber only type gasket main body, and a carrier sheet which is made of a resin film retaining the gasket main body in a non-bonded state, and the carrier sheet is provided with an air inflow port for making air flow into a portion between the carrier sheet and the gasket main body when the gasket main body is detached from the carrier sheet. A gasket retention portion having a three-dimensional shape which is deformed along an outer shape of the gasket main body is arranged at a position which laps over the gasket main body in a plane in the carrier sheet, and the gasket main body is partly accommodated within the gasket retention portion in a thickness direction.

  • Publication number: 20190257426
    Abstract: A gasket includes a reinforcing body made of a resin film, a one-side gasket body on one surface of the reinforcing body, and another-side gasket body on another surface of the reinforcing body. The reinforcing body has, between both gasket bodies, a three-dimensional shape in which the resin film is bent. The one-side gasket body includes an inversely-tapered engaging convex portion protruding toward the other-side gasket body, the reinforcing body includes a deformation portion as the three-dimensional shape deforming along a shape of the engaging convex portion, and the other-side gasket body includes an inversely-tapered engaging concave portion embedding therein the engaging convex portion and the deformation portion. At least one of the one-side gasket body and the other-side gasket body includes a flat surface-shaped seal surface, and the reinforcing body has a convex shape as the three-dimensional shape protruding toward the flat surface-shaped seal surface.

  • Patent number: 10350799
    Abstract: The purpose of this invention is to make it easy to handle all-rubber gaskets. To achieve this purpose, a gasket is characterized in that a gasket body of only rubber is combined with a carrier film that is made from a resin film to hold the gasket body in a non-adhesive state. A three-dimensional portion having a shape that is deformed along the external shape of the gasket body is provided at a position where the gasket body and a plane of the carrier film overlap, and a portion of the gasket body is contained in the three-dimensional section. The gasket body is used as a gasket for fuel cells incorporated into a fuel cell stack.

  • Patent number: 10103364
    Abstract: A seal with an integral base material in which a gasket is formed integrally with a film, sheet, or plate-shaped base material, wherein space saving is achieved by making the width of the gasket as small as possible. In order to achieve the foregoing, the following are provided: the film, sheet, or plate-shaped base material; the gasket that is provided integrally with the base material and that is formed of a rubbery elastic material; and a fill layer formed by the rubbery elastic material that is filled into a through hole that is provided in an open state in the base material. A portion of the fill layer is connected to the gasket and another portion extends out from the gasket at substantially the same thickness as the base material.

  • Patent number: 8869354
    Abstract: Provided is a ratchet buckle for helmets wherein an engagement/releasing member having an engagement part is assembled to the buckle, via a pin, between the base member and operating member, and therefore when the operating member is pulled up and rotated in the counterclockwise direction, the front end of the operating member contacts the front end of the engagement/releasing member and the engagement with the tab of the ratchet is released by rotation of the engagement part of the engagement/releasing member, and because the engagement is released by pulling up the operating member by at least twice the conventional pull-up distance, the helmet will not come off from the head as a result of a wrong or inadvertent lever operation and thus safety can be ensured, while the thickness of the ratchet buckle can be kept small.
