Abstract: A ball screw including a threaded spindle and a spindle nut has a ball deflector arranged in an opening in the lateral surface of the spindle nut. The ball deflector is formed with an upper shell and a lower shell, the lower shell being arranged radially inwardly closer to the spindle nut longitudinal axis than the upper shell. The lower shell has a substantially half-shell-shaped contour. Both the upper shell and the lower shell are fastened in the spindle nut without any further, discrete mechanical fastening elements, and the ball deflector formed thereby does not protrude beyond the outer contour defined by the spindle nut.

Abstract: A facade panel screw for the optimized fastening of facade panel elements on a substructure has a head with very large diameter DK, a substantially cylinder cross-sectional shaft, which is at least partially provided with a thread (nominal diameter DS) and a conical tip comprising a tip angle ?. The thread extends continuously from the shaft to the tip. It is characterizing that the tip angle ? is 45°+/?10°, the thread is embodied at least in a two-threaded manner, the head diameter DK is embodied at least twice as large as the nominal diameter DS; and the facade panel screw does not have a drill tip. Such a facade panel screw is used in a fastening arrangement, which comprises a load-bearing component (substructure) and a facade panel. Due to its design, the facade panel screw is able to simplify the fastening of the facade panel and to at least partially correct an inclined positioning in response to the installation.

A method for releasing a snap-in connection between a holding device (10) and a component (12) is also provided, having the following steps: generating a magnetic field in the vicinity of the holding device (10); and applying a force that moves the holding device (10) and the component (12) apart from each other to release the snap-in connection.

Abstract: A holding device for a wall module 10 of the cabin lining in an aircraft includes two different clamping devices. The first clamping device 30 has a clamping body 33 having a first clamping jaw 31, which is fixed relative to the clamping body, and a second clamping jaw 32, which is movable relative to the clamping body 33, which in turn is operatively connected or can be temporarily connected to an actuating lever 35. In the closed state, the clamping jaws 31, 32 form a receiving space 36 for the wall module 10. An interlocking device 37 fixes the position of the clamping jaws 31, 32 relative to one another in the closed state.

Abstract: An adjustable hidden or invisible hinge for mounting a door-panel or window sash to a frame is provided that is useable for either rebated or flush mount applications using the same hinge. This is possible due to the use of two different types of arm systems that connect the frame part of the hinge to the sash or door part. These include a rotational lever arm system that allows for 180° guided rotational movement which is combined with a translational arm system that at the same time superimposes a translational movement of the sash movable body relative to the sash body.

Abstract: A spindle nut (S) for a ball screw is conventionally designed as a hollow cylinder with a central-symmetrical middle longitudinal axis (Z). The spindle nut has an internal thread, which is designed as a ball groove (K) arranged on the cylinder inner surface. Pairs of load-relief bores (B) serve as substantially cylindrical channels for guiding the balls out of and into the ball channel (K) through the wall of the spindle nut. Each load-relief bore (B) is distinguished by a generatrix (L), which has an intersection point (C) with the thread base line of the ball channel (K) and constitutes the geometric continuation of the traveling path of a ball from the ball channel (K) into the load-relief bore (B). A tangent (T) to the cylinder surface (G) runs in a parallel manner at a spacing a >0 to the generatrix (L), both T and L being perpendicular to a common normal (R) to the middle longitudinal axis (Z).

Abstract: A sleeve for the centering of fasteners when installing structural parts on substructure of a building envelope is designed substantially as a hollow cylindrical sleeve body or split hollow cylindrical sleeve body. It has at least two gutter-like shell elements each having a head end and a rear end. The shell elements are grouped symmetrically about a central axis A and span between them a middle space with inner surfaces facing each other. The shell elements are spaced apart from each other and separated by axially parallel longitudinal slots, except for a connecting joint section at the head end. These sleeves are placed on a fastener and allow a precise centering in the predrilled hole of a facade plate, for example. The sleeve remains in the predrilled hole until such time as the centering of the fastener has been accomplished and is then ejected safely by driving the fastener home.

Abstract: A self-drilling screw (10) having a head (20), a shaft (30) at least partially wearing a thread (35) and a drill point (40). The base material of the screw (10) including the drill point (40) is integrally manufactured from an austenitic 300 series steel with a surface hardness (uncoated) of 400-600 HV 0.3. The surface of the screw has a top coating of Zn—Ni with a Ni-content between 12-15% deposited on the austenitic base material. This self-drilling screw (10) is manufactured from a blank of raw austenite 300 series steel which is initially squeezed by cold forming to reduce its diameter in a first operation and, in following cold forming operations the head, the drill point and a thread are formed.

Abstract: A facade panel screw for the optimized fastening of facade panel elements to a substructure has a head having a very large diameter, a subsequent, essentially cylindrical shaft section (22) extending along a central longitudinal axis (A) and a subsequent tip region (23). The shaft section (22) includes, as viewed from the head, a threadless underhead section (24), a stop collar (25) and a threaded section (28). The thread in a first part (26) of the threaded section (28) subsequent to the stop collar (25) has an outer diameter Dr, which is attenuated compared to the thread in a second part (27) with outer diameter Dn, over several convolutions, so that Dr<Dn. This threaded section 26 allows a controlled overwinding of the facade panel screw in use. A corresponding fastening arrangement includes a facade panel, a substructure for transferring the load to a building surface and the facade panel screw.

Abstract: A sleeve (20) for centering fasteners during the assembly of components such as facade elements on the substructure of a building envelope includes a sleeve body (23) and a connection bracket (25). The sleeve body (23) has a plurality of sleeve elements (21, 22) which are grouped around a central center axis A and are spaced apart from each other by gaps running in the sleeve longitudinal direction. At least a first (21) and a second (22) sleeve piece are connected to each other at an axial longitudinal end of the sleeve body (23) by a separable connection bracket (25), preferably the connection bracket is separable via predetermined breaking points. Such a sleeve is used in the construction of facades, wherein it is inserted into a pilot hole of a facade element, the connection bracket is broken off and a fastener is inserted into the sleeve. Driving the fastener centers the fastener in the sleeve and the sleeve is removed from the pilot hole.

Abstract: A facade element holder includes first and second profile elements, the first profile element having two sections A and B. Here, section A has a first surface shape X and section B as a second surface shape Y. The second profile element has two sections C and D with a first surface shape X? and a second surface shape Y?. X and X? and Y and Y? have substantially the same contour diametrically oppositely in pairs, the spacings from A to B and from C to D being chosen to be substantially equal.
