The invention relates to a self-drilling screw (10) made of an austenitic or other stainless steel, comprising a shaft having a thread-forming region and a drilling tip (16). The shaft (12) is made of an austenitic or other stainless steel as one piece and is provided with a galvanically applied thin layer (20) at least in the area of the tip, whereby the area provided with the layer (20) is harder than an uncoated area, wherein the thin layer (20) has a pearl- or columnar-structured surface, a layer thickness of at least 2 µm and preferably up to 30 µm, and a hardness in a range of 500 to 1500 HV0.3. The self-drilling screw (16) is easier to produce than a common self-drilling screw, in which the drilling tip is made of a harder material than the shaft and is welded to the shaft made of stainless steel. The self-drilling screw (16) is thus a fully austenitic self-drilling screw made of a base material, which is provided with a hard coating. The coating ensures the drilling performance and the thread forming. In addition to the lower manufacturing costs, the corrosion resistance of the self-drilling screw (16) is a further advantage.
What is described is a bolt-like fastening element (30), which is preferably in the form of a drilling screw shaped by pressing and/or rolling, having a head portion (LK), which has a holding region (LH) and has a starting hardness, and also having an initial portion (LA), which adjoins the head portion (LK) by way of a transition region (LÜ) and is additionally inductively hardened. The fastening element (30) is produced by cold forming from a blank made of a carbon steel having a starting tensile strength of at least 800 N/mm2. The induction hardening of the fastening element extends only to the initial portion thereof, i.e. in the case of a drilling screw to the drill bit (24) and the first turns of the thread (36). After the induction hardening, the drilling screw substantially has the starting tensile strength and is ductile in the head portion (LK). In the initial portion (LA) as far as into the central axis (33), the drilling screw is fully hardened to a hardness which is at least twice the magnitude of the starting hardness in the head portion (LK). The notched-impact energy in the head portion (LK) of the bolt-like fastening element is at least three times that in the initial portion (LA).

A frame (42) extends upwards from the undercarriage (30), wherein the device (20) can be manoeuvred using said frame. The pressing element (40) comprises a heating device (46), which is designed as an induction coil, by means of which the metal plate, which is provided with an adhesive or weldable coating, can be heated. An induction generator and a control and cooling device thereof are mounted in or on a housing (50), which is fixed to the frame (42) at a distance (A) above the undercarriage (30). The device (20), which is formed as one part, can be tilted for moving around a castor axis (28) and can then be lowered via the metal plate onto the membrane.
Described are a screw (10) and a connection produced therewith of a thin metal sheet forming a substructure (40) to a plastics component (30) having a through-bore (32) and having a seal (50) located between the substructure (40) and the component (30). The screw (10) has a shank (13) having a thread-cutting thread (16) and a tip (12) in the form of a boring part, and also a lower thread section (18) having a first thread outside diameter (D18) and an upper thread section (19) having a second, larger thread outside diameter (D19) and having a conically narrowing thread section (22) between the two thread sections (18, 19). The upper thread section (19) has a thread pitch (P2) which is smaller than the thread pitch (P1) of the lower thread section (18). During the production of the connection, the upper thread is screwed into the through-bore (32), wherein a form-fit is produced in the component (30) between the latter and the screw (10) and the material of the component (30) rests in a sealing manner around the upper thread section (19). This produces a combination of a seal without a sealing washer and with a defined distance between the component and the substructure by defined compression of the seal (50). Fig. 1c
The invention relates to a connection (20) of at least one component (12) made of steel to a substructure (16) made of wood by means of at least one screw (22) having a head (23) and a shaft (27) having a thread (25). The or each screw (22) is supported in a region underneath the head (23) against and/or on the or each component (12) by means of a coupling device (28) that guides the screw (22) when establishing the connection (10) and is furthermore designed such that said coupling device lends the connection (10) ductility, at least after the production thereof. The connection behaves stiffly at a low load level and in a ductile manner at a high load level. An uneven load on screws arranged in a row in the direction of force in a connection, caused by production tolerances of the screw (22), can be substantially equalized as a result of the ductile behavior of the coupling device (28).

The invention relates to a threaded spindle (11), having a drive part (20), which has a longitudinal axis (A) and is mounted by a first journal (70), and having a threaded part (30), which likewise has a longitudinal axis (B), and having a threaded nut (50), which is mounted by a second journal (80a; 80b) and in which the threaded part (30) is guided. The drive part (20) and the threaded part (30) are formed as separate parts and are each provided with at least one coupling element (25, 55), which are connected to each other in an articulated manner by plugging together. A mutual offset or inclination angle (a) of the longitudinal axes (A, B) of the drive part (20) and of the threaded part (30) can be compensated in this manner. The two-part threaded spindle (11) forms a threaded drive with the threaded nut (50) thereof, which can for example be used in a parking brake of a vehicle braking system. The swinging function created between the drive part (20) and the threaded part (30) reduces transverse forces, which increases efficiency and reduces wear compared to a known threaded drive with a single-part threaded spindle.

After manual actuation of the disengagement device (30), the screwdriver (24) can be introduced in the shaft (11) of the insulating material holder (10) and positively engaged with the fastening screw to be set. After the fastening screw has been set, the tool (20) can be moved back into the starting position thereof by another manual actuation of the disengagement device (30), the tool in said position being ready for installing the next insulating material holder (10).
What is described is a device for fastening equipment parts such as photovoltaic panels on a sandwich or single‑shell building envelope using a plurality of fastening elements (20, 20') in the form of bolts, which can be supported at least by a connection part (30, 30') and on a load‑bearing part (12) of the building or the building envelope. If the outer shell (14) is present, the fastening elements (20, 20') can be guided through the outer shell (14) and supported on the load‑bearing part (12) and/or the outer shell (14). Each fastening element (20, 20') can be positively engaged with the connection part (30, 30') and/or, if present, with the outer shell (14) so as in each case to support the connection part (30, 30') on the load‑bearing part (12) and, if present, on the outer shell (14).
The invention relates to a screw (30) having a shaft (32) comprising a wooden thread (34) and to a connection of a component (10) to a substructure (20) made of cross-cut timber or brittle material, produced using said screw. The shaft (32) is designed as a ductile strain region (40) for a portion of the length thereof, said region being plastically deformable over the majority of the usable tensile strain. The screw is made of a low-strength steel having a tensile strength of 200 to 800 N/mm2. The screw (30) is not pretensioned when producing the connection. The tensile force that can be transferred between the wooden thread (34) and the substructure (20) is greater than the maximum tensile force that can be applied to the strain region (40). The anchoring of the wooden thread (34) and the diameter Dh of same are thereby selected with respect to the implementation of the strain region (40) so that the strain region (4) fails before the threaded connection in the region of the anchoring of the wooden thread (34) fails. The intrinsically brittle cross-cut grain connection becomes a ductile joint by using the screw (30) according to the invention.
The invention relates to a device (100) for securing a support structure such as solar module-carrier (12) to a flat roof (16) which is provided with a non-bearing insulation layer (24) covered by a sealing strip (22). The device (100) has an upper connection element (150) for the support structure and a spacer member (120) which can be guided through an opening (26) in the insulation layer (24) in order to support the connection element (150) on a roof substructure (17). The spacer member (120) is anchored by a plurality of anchoring parts (28) on the roof substructure (17). The connection element (150) comprises an upper and a lower connection flange (152, 154) between which the sealing strip (22) is clamped. The spacer member (120) is designed as a profile or hollow-profile part which can be cut to length as required and is produced as an extrusion part from a thermal insulation material.
Setting device with a variable setting stroke adjustment and method of setting the setting stroke of setting device. Setting device includes a housing, a pulling rod structured and arranged for movement in an axial direction, an adjustably positionable stop element structured and arranged to adjustably limit a setting stroke of the pulling rod, and a locking element movable between a closed position and an adjustment position. The stop element has at least one region with a polygonal contour, and, in the closed position, the locking element engages in a path of motion of edges of the polygonal contour and, in the adjustment position, releases the path of motion.
A self-tapping screw is described with a drilling part and a shaft (14) which is provided with a thread (12) and a core diameter (Dk). The drilling part has a drilling tip (20) which is arranged eccentrically in relation to a longitudinal axis of the screw, and is configured as a sickle tip (101) which has a primary cutting edge (30) and a secondary cutting edge (40). The primary cutting edge (30) is formed by the intersection of a cutting surface (60) and a main free surface (90) and extends from the drilling tip (20) parallel to the longitudinal axis of the screw. The secondary cutting edge (40) is formed by the intersection of the cutting surface (60) and an auxiliary free surface (70) and extends obliquely with respect to the longitudinal axis of the screw over the width of the drilling part. A hole with the core diameter (Dk) can be produced by way of the screw, into which the thread (12) cuts a counterthread. As a result of the joint action of the primary and secondary cutting edges (30, 40), the fibres are severed during the drilling operation when a workpiece is made from wood, so that the screw develops practically no splitting action.
The connecting arrangement is used to detachably connect two components (18, 20) that are provided with openings which are aligned with each other. A bolt (2) that is guided in a sleeve is provided in the bore of the one part (20) that is to be connected. The sleeve (4) and the bolt (2) protrude through the opening of the other component (18). An emergency opening mechanism is formed by forming a stop surface (14) in a recess on the bolt (2), said stop surface forming an angle (W) of less than 90 degrees and in particular less than 45 degrees with the axis of the bolt (2). A leaf spring (6) that is fixed to the sleeve (4) is shaped at the spring end (12) such that the stop surface (14) forms a positively engaging stop with the spring end (12). The angle (W) and the spring force of the leaf spring (6) are selected such that when a triggering force that exceeds the clamping force of the leaf spring (6) acts axially on the bolt (2) in the direction of the opening, the leaf spring (6) is forced apart and thus disengaged from the stop surface (14).
The device includes pneumatic and hydraulic cylinders, a switch valve connecting the pneumatic cylinder either to an outlet channel or a pressure supply, and an actuating element to switch the switch valve into a second position connecting a control line, open to the environment until closed by reaching a setting limit, to a pressure supply via a throttle and the switch valve. A pressure control valve having a control chamber connected to the pressure supply is structured so that pressures in the control chamber and the control line act on first and second control surfaces in the first and second switch position directions, respectively. The actuating element relieves pressure on the control chamber to move the pressure control valve into the second switch position to connect a motor line and switch channel of the switch valve to the pressure supply, which switches the switch valve into the first position.
The invention relates a fastening system (10) for overhead storage bins (12) on a supporting structure that can be mounted in a suspended manner. Said system comprises at least one pair of suspension eye lugs (20, 22) attached to a supporting structure (14) or to one of the overhead storage bins (12). The suspension eye lugs (20, 22) are detachably interconnected by a main pin (40), receivers for the main pin which are attached to the suspension eye lugs being in alignment in a mounting position of the overhead storage bin. A part of the ramp is designed as a sloping ramp and a main pin guide is provided in the receiver of one of the suspension eye lugs. The main pin (40) is spring-loaded in the main pin guide (50) in the direction of the other suspension eye lug and has, with the overhead storage bin (12) not yet mounted, an end position in which the main pin (40) is deployed from the main pin guide (50). The fact that a portion of the suspension eye lugs is designed as a sloping ramp allows the main pin (40) to be deployed in the receiver of the other suspension eye lug by the action of the preload during the upward movement of the overhead storage bin (12) and its suspension eye lug into the mounting position.
The invention relates to a lock (20) on a luggage box (22), in particular in the cabin of an aircraft. The luggage box (22) has a closable lid (28) which is movable about an axis of rotation (26) and supports a latch bolt support (40) with at least one main latch bolt (30) and a closure housing (80) for holding at least the main latch bolt (30) for latching the lock (20). Either the luggage box (24) or the lid (28) receives or supports the latch bolt support (40) and the other receives or supports the closure housing (80). The lock (20) is or can be connected and has an actuating mechanism (100) which can be actuated manually in order to release the main latch bolt (30) from the closure housing (80) to unlock the lock (20). The main latch bolt (30) in the latch bolt support (40) is pivotably mounted and in the latched position of the lock (20) is gripped in a blocking receptacle (60) of the closure housing (80) and bears against a main closing surface (63) of said receptacle. A further auxiliary latch bolt (50) is mounted on the latch bolt support (40) and in the latched position of the lock (20) said auxiliary latch bolt can also be blocked in a more or less correct latching position relative to the main closing surface (63) by an auxiliary closing surface (68) formed on the closure housing (80). The main latch bolt (30) closes in the blocking receptacle (60) of the closure housing (80) by positive engagement, whereas the auxiliary latch bolt (50) closes with a gap (69). The auxiliary latch bolt (50) is movably mounted in the latch bolt support (40) and closes in the closure housing (80) with a gap (69) around it, wherein a rocker (54) having a pin (58) is associated with the auxiliary latch bolt (50), which pin engages in a recess (59) in the auxiliary latch bolt (50) in the unlocked state of the lock (20), so that in the unlocked state of the lock (20) the auxiliary latch bolt (50) is retained in positive engagement in the latch bolt support (40), whereas when closing the luggage box (22) the rocker (54) is forcibly actuated by the closure housing (80) and thus the auxiliary latch bolt (50) is unlocked, but only when the closure housing (80) and the latch bolt support (40) are in a position relative to one another in which both latches (30, 50) can latch.
The invention relates to a lock for a luggage box installed overhead in the cabin of an aircraft, comprising a stationary housing and a cover that can move about a rotary axis. The lock comprises a locking pin device that can be mounted on the housing, comprising two locking pins (32, 32b) disposed in parallel, a catch (20) that can be mounted on the cover and that has two locking hooks (55, 55b) that can be pivoted about a pivot axis (22, 22b) for receiving the locking pins (32, 32b) for locking the lock (10), and a manually actuatable drive device (60) for jointly pivoting the locking hooks (51, 51b) away from the locking pins (32, 32b) for unlocking the lock (10). The drive device (60) comprises a gear rack (62) and a sliding element (64) that can be linearly displaced against the pressure of a spring element (70). The locking hooks (51, 51b) are each connected to the gear rack (62) or the sliding element (64) by a knee joint (74, 74b) that is hinged to the closing hook (51, 51b) adjacent to the pivot axis (22, 22b) thereof in such a way that the lock can be opened again only by tensile force acting on the hinged point of the knee joint (74, 74b) on the locking hook (51, 51b). This allows the functions of fail-safe and positive locking, which are required in aero technics, in a simple manner, wherein positive locking is achieved in that the knee joints (74, 74b) can each be brought into an end locking position in which said joints are mechanically locked and thus automatically prevent the lock from opening due to overload or vibration.
Disclosed are a locking mechanism (100) and a lock (110). The locking mechanism (100) comprises a push-button (148) connected to a freewheel (154) via a traction cable, said freewheel being connected to a drive device (160) of the lock (110). A baggage compartment in the cabin of an airplane usually comprises two locks (110) of this type which can be unlocked by the push-button (148). A freewheel (154) arranged between the push-button (148) and the lock (110) ensures that the push-button (148) remains in a pushed position as long as each lock (110) allocated to the baggage compartment is not in a correctly locked position. It can be identified from the position of the push-button of the baggage compartment whether both locks of the baggage compartment are correctly snapped in.
The invention relates to a plastering system (10) for a façade of a building. The system comprises a steel net (20) for reinforcing a plaster layer and fastening means (22, 30, 40) for fastening the steel net (20) to the façade. According to the invention, the fastening means comprise a comb-shaped fastener (22) for attaching the steel net in a hanging position on the building structure. The steel net (20) is modified such that said net has angled parts (28) which produce a distance between the steel net (20) and an insulation (16) bearing the plaster layer. The fastening means furthermore comprise a plastic anchor (30) having a head (31) and a metal screw (32) for fastening the insulation (16) to a wall (14) of the building structure.

FASTENING SYSTEM FOR HANGING MOUNTABLE OVERHEAD CONTAINERS
The invention relates to a fastening system (10) for hanging mountable overhead containers (12) such as baggage compartments in an airplane. Said system comprises at least one pair of support eyes (20, 22) mounted on a support structure (14) or on an overhead container (12). The support eyes (20, 22) can be detachably connected to each other by a pin (30) that can be drawn back in a pin guide (40) and thereby spring-loaded in the exit direction. When the support eye (22) attached to the overhead container (12) is inserted into the support eye (20) having the pin guide (40) when installing said container, the pin (30) is unlatched in the pin guide (40) and automatically moves out into the support eye (22) attached to the overhead container (12). Using a lever joined (60) to the pin guide (40) by a hinge, the pin (30) can be moved out completely into an end position, and locked in said position. In order to remove the overhead container (12), the lever (60) must simply be pivoted back.
The invention describes a system for fastening a panel such as a sandwich floor panel to an underlying structure such as a seat rail of an aircraft by means of a screw connection with a facility for securing the screw connection against loosening of the screw (14) and nut (12) as a result of vibration. The screw (14) is provided with an end region (16) which is non-circular in cross section. A securing element (40) is rotationally fixedly connected to the nut (12) and is in elastically resilient and positively locking engagement with the non-circular end region (16). In this fastening system, the screw securing facility is decoupled from the threads of the screw (14) and the nut (12), and therefore permits a considerable number of tightening and loosening cycles of the screw connection. The nut (12) is a blind rivet nut which is fastened to the underlying structure. The screw connection brings with it only a small additional weight, such that the fastening system overall has a low weight and is particularly suitable for use in aircraft.
The invention relates to a self-tapping screw comprising a drive part, a thread part (30), a drilling part (40), and two blades (42) freely projecting transversely to the screw axis (12) on the drilling part (40). The boundary of each blade (42) facing the drilling tip (44) is designed as a cutting edge (48). The screw has a core drilling cone (50) on the main cutting edge (46) thereof, which core drilling cone has a height (S). The cutting edge (48) of each blade (42) extends at least partially axially at least into the area of the height (S) of the core drilling cone (50). The blades (42) drill a hole in a softer layer at a drilling diameter (110). When or before the drilling tip (44) begins to drill a core hole in an adjoining harder layer, the blades (42) hit the harder layer and break off. A passage shock to the blades (42) is thereby avoided, which passage shock would occur if the blades (42) were arranged at such a large axial distance from the drilling tip (44) that the blades first hit the harder layer when the core hole has already been completely drilled by the drilling part (40). Therefore, the breaking off of the blades (42) does not depend on the drilling pressure that the operating person exerts on the self-tapping screw.
The invention relates to a holding device (10) for use during the installation of a component (60) to be fastened vertically to a support structure (50) such as that of an aircraft, for example a cabin sidewall lining part. The holding device (10) comprises a hook (12) and an eyelet (14) receiving the hook, said hook and eyelet being designed so that they can be fastened to the support structure (50) or the component (60). The eyelet (14) has at least one elastically resilient element for the movable mutual support of the eyelet (14) and hook (12). The holding device (10) facilitates the fastening of a perpendicularly installed component (60). The elastically resilient element allows the component (60) to be pre-positioned in a nominal position.

What is described is a self-boring screw (2) comprising a bore section (6) attached to the free end of the screw shaft (4), two vanes (12) radially protruding from said bore section, the border of said vanes facing toward the bore tip (8) of the bore section (6) being configured as a boring blade (13). The bore section (6) comprises a chip discharge zone (14) that is configured such that the border of the vanes (12) facing toward the bore tip (8) forms a cutting point (S) with a bore radius (16), said cutting point having a distance (A) to the screw shaft (4) that is at least 2/3 of the cutting edge length of the bore tip (8). The chip discharge zone (14) makes it possible that the chips produced by the boring blade (10) at the bore tip (8) can be discharged freely and without buildup. The material cut by the boring blade (10) is conveyed as chipped material away from the bore tip (8) in the direction of the cutting point (S) at a lower vane connection (15) as a result of the rotational motion of the screw (2), thus ensuring unhindered chip discharge. It is possible to compress the chips to be discharged to a maximum of 2/3 of the cross section occurring after the cut. This ensures that even critically sized chips are removed without blocking the discharge of chips from the area of the bore section (6).
