Abstract: The present invention relates to both a proceeding and means for, in connection with hole making in a wall (1), for the mounting of items on the moisture-proof walls (1) of a wet area by means of an expandable mounting element (2), providing sealing of the hole. According to the invention, in addition to an expansion (I) of the mounting element (2) behind said wall (1), there is also provided an internal expansion (II) of the mounting element (2) in the receiving hole (3) of the mounting element (2) in question in the wall (1). There is furthermore provided a liquid-proof cover (III) around the entire mounting element (2) in question introduced and expanding in said receiving hole (3).

Abstract: A fastener (11) in the form of a strip (12) of material in the form of a ring which in plan view is profiled to conform to an annular gap (H) between a first component (A) bounded by the fastener (11) and a second component (B) bounding the fastener (11); the ring member having ends providing a gap (G) in plan view; the strip of material having a first side (14) and a second side (15); and having a series of integral fingers (16-23) spaced along the length of the ring and projecting, in plan view, outwardly from the ring whether from the first side (14), the second side (15), or both sides thereof. In a further version the ring includes a further series of discrete projections formed integrally from the strip and lying around the ring member in between members of the series of fingers.

Abstract: A push nut fastener has first and second gripping openings. The first gripping opening is substantially circular and the second gripping opening is substantially rectangular. The substantially circular gripping opening has a plurality of blades or finger-like engagement portions extending from the outer circumference of the substantially circular gripping opening towards the center of the substantially circular gripping opening. The substantially rectangular gripping opening has a plurality of blades or finger-like engagement portions extending from the outer perimeter of the substantially rectangular gripping opening towards the center of the substantially rectangular gripping opening. The substantially rectangular gripping opening includes at least two blades or finger-like engagement portions, a respective blade extending from each of two opposing sides of the substantially rectangular gripping opening. The push nut may have flanges formed at two opposing ends of the member.

Abstract: A fastener has a receptacle (1) and a stud (10), the receptacle (1) having a pair of clip-like legs (6) the ends of which engage in grooves (16) in the shank of the stud (10). Each of the legs (6) has a plurality of formations (8) on its inner surface, the formations being shaped so as to engage the wedge-shaped lead-in portion (14) of the stud as it is inserted into the receptacle so as to rotate the stud into a position in which the legs (6) of the receptacle must engage in opposed grooves (16) on the shank of the stud.

Abstract: A screw anchoring device and method for preassembled aperture sealing attachment with an apertured panel to confine insulating material foamed in place between the panel and a spaced wall. The screw anchoring device includes a flat portion having a central helical screw receiving impression with a retained knock-out central area capable of being displaced by a screw. The device is secured to the apertured panel with a screw receiving impression overlying the panel aperture. The screw anchor device has one or more wing portions formed integrally with the flat portion, said wing portions diverging from the plane of the flat portion in a direction away from the screw receiving impression and adapted to be imbedded in the foamed insulating material.

Abstract: A heat-up/cool-down bimetal timer for an electric toaster wherein a unique screw fastener is provided for holding a calibration adjustment screw without being deformed during automated adjustment of the screw. The fastener is made from a blade of spring sheet metal that has an end turned on itself in the form of a cylinder for holding the calibration screw. Thus, the axis of the screw is parallel to or even in line with a plane that lies midway between the planes of the major surfaces of the sheet metal fastener. Accordingly, any automated screw driving equipment that may push downwardly on the head of the screw for adjusting it normally would not flex or bend the fastener in a plane perpendicular to one of its major flat surfaces.
