The invention describes a system for fastening a handle to a kitchen container that comprises a plate-like fastening element, configured for being irremovably constrained both to a wall of the kitchen container, and to the handle. The plate-like fastening element is configured to be housed and restrained in a corresponding blind hole obtained at an end of the handle. The plate-like fastening element comprises at least one inclined hooking wing, integral with the plate and projecting below one of its surfaces. Each inclined hooking wing is configured for inserting, through elastic deformation while switching from the disassembled configuration to the assembled configuration of the fastening system, into at least one corresponding concave portion obtained on an inner surface of the blind hole towards which each inclined hooking wing projects in the assembled configuration of the fastening system.

A fastener includes a head that is configured to be engaged by a tool, and a shaft extending from the head. The shaft includes a distal end that is opposite from the head. At least one optical component is coupled to one or both of the head or the shaft. The optical component(s) is configured to allow light to pass through the fastener. A window system includes a panel that includes an exterior surface and an interior surface, and the fastener extending between the exterior surface and the interior surface of the panel. A screen is coupled to the interior surface. The screen receives light from the optical component(s) of the fastener.

The present invention relates to a corrugated steel sheet, and provides a corrugated steel sheet (B) having an inclined portion in which the position of a coupling hole is adjusted, wherein: among a pair of corrugated steel sheets (A, B), a corrugated steel sheet (B) is overlapped and joined with the upper portion of a lower corrugated steel sheet (A) and has the same thickness as the lower corrugated steel sheet (A); a common bolt is coupled to both a coupling hole in the lower corrugated steel sheet (A) and a coupling hole in the corrugated steel sheet (B); and when assuming that the distance between the center of a middle crest portion coupling hole (111) and the center of an adjacent inclined portion coupling hole (141) is a coupling hole distance (a, b), the coupling hole distance (b) for the corrugated steel sheet (B) is calculated by equation 1. Therefore, the present invention can obtain a stable bolt coupling strength, can minimize the occurrence of a gap in a joint corrugated steel sheet structure in which the corrugated steel sheets are overlapped and joined together, thereby improving the waterproof performance thereof, and can facilitate bolt coupling work, thereby improving constructability on the site.
