摘要： The expansible anchor consists of a shank having a threaded portion for fixing an article at its rear end and a reduced cross-sectioned portion with an adjoining expander cone at its front end, and, positioned over the reduced cross-sectioned portion, an expansible sleeve having longitudinal slits forming expansible segments and locking elements protruding beyond the diameter of the expansible sleeve and arranged on the expansible segments. To increase the holding force of the anchor and to allow the expander cone to slide-up and the expansible sleeve to expand in operation if the drilled hole become enlarged as a result of cracks forming, the locking elements consist of several interconnected punched elements on each expansible segment extending in a longitudinal direction of the expansible segments. Each punched element is triangular with a point directed towards the front end of the expansible segments. An improved method of making the expansible anchor which includes stamping a blank for the expansible sleeve somewhat undersized from sheet metal, subsequently pressing it and then punching the punched elements in the expansible sleeve is also described.

摘要： A fixing element has an expansion zone formed by a longitudinal slot having a trapezoidal cross-section and produced by stamping, and an expander member inserted in the longitudinal slot and displaceable therein. On the two sliding surfaces of the longitudinal slot arranged at an angle to one another the expander member rests with its two bearing surfaces, likewise arranged at an angle to one another. The external surface of the expander member provided with teeth of roof-shaped construction projects beyond the shank of the fixing element at least with a part of the height of the teeth. The expander member lying in the longitudinal slot so that it is easily displaceable allows subsequent expansion of the anchored fixing element in the event that the drilled hole widens as a result of cracks forming.

摘要： An arrangement for mounting a flexible film or the like on a substrate has an inner clamping member connected with a substrate and having an undercut portion adjacent to the latter, an outer clamping member surrounding the film in the region of the undercut portion of the inner clamping member so that the film is clamped between the inner and outer clamping members, and a disc-shaped carrying member associated with the outer clamping member so as to be pressed by the latter against the film and carrying a locking element arranged to lock the outer clamping member in clamping condition.
