Abstract: A rigid cover assembly for a vehicle roof opening which includes a cover plate, a reinforcement frame supporting a lower peripheral edge of the cover plate, and a plastic frame surrounding the cover plate and enclosing the reinforcement frame. A sealing strip is provided on the outer peripheral edge of the plastic frame and includes a slot receiving a rib and fixing elements projecting from an outer edge of the plastic frame. A metal gap compensating element is embedded in the sealing strip outward of the plastic frame and is capable of being permanently deformed in a transverse direction. The sealing strip has a section between the metal gap compensating element and the slot and an outer edge section that is substantially more capable of deformation than the section between the metal gap compensating element and the slot.

Abstract: In a sliding or sliding-lifting roof for a car, a lid, associated with a roof opening for the purpose of completely closing it, has a front edge which is wedge-shaped in cross-section. A sealing profile, sealingly filling the gap between the fixed vehicle roof and the lid when the lid is closed, is pushed from below onto a downward flange of the fixed vehicle roof and is deformable to form a trough, generally complementary in shape to the wedge shape. The wedge-shaped front edge here engages generally form-fittingly and force-transmittingly into the sealing profile, so that the lid, at its front edge due its engagement with the sealing profile, is reliably secured against high uplift forces, such as occur at high speeds of travel.

Abstract: A rigid lid for a sliding roof or a sliding-lifting roof, the lid having a lid shell, provided with a peripheral 90.degree. cranked edge, is painted separately from the other parts of the roof construction constituting a pre-assembled unit and is not installed until the pre-assembled unit has been installed into the bodywork of the automobile. The lid shell is secured by detent engagement to the reinforcing frame or to a holding frame fixed thereto after positioning and under the action of force from above. The edge gap sealing profile is secured to the reinforcing frame by pushing on from below before the lid shell is fitted.

Abstract: A sliding-lifting roof for an automobile of a very low overall height has, in addition to guide links fixed to the side edges of a lid, control links, which are disposed on each side of the lid and each rigidly connect the front sliding element with a guide element, disposed behind the rear sliding element. The sliding elements and the guide element are slidably guided on the same guide rail. A two-armed control lever is disposed on each side of the lid, which lever engages with a central control pin into the control link, engages at its outer end by a guide pin into the guide link and is articulated at its inner end to the rear sliding element. The lid movements are achieved by a sliding drive of the rear sliding element.

Abstract: In a sliding lifting roof for motor vehicles a water trapping strip is resiliently fixed to a water deflector underpinning the rear marginal gap between a trailing edge of a sliding cover and the rear edge of the roof opening. The water trapping strip is biased by spring tension in the sense of an upward displacement, so that when the sliding cover is open it projects upwards over the rear edge of the roof opening with a splash guard. In the case of braking during forward travel and with the sliding cover open, splashed water from the surface of the rear, fixed vehicle roof is trapped by the splash guard and is passed by the water trapping strip to the underlying water deflector.

Abstract: An air guide device, which is suitable both for sliding roofs and for sliding-lifting roofs, comprises a wind deflector plate, pivotally journalled by hinge assemblies beneath a front, fixed automobile roof, the pivotal movements of which deflector plate are controlled by control members, displaceably driven by the drive system of the sliding lid, which control members for this purpose bear from above on control surfaces formed on the wind deflector plate. The control members do not release the control surfaces until, in the opening displacement of the sliding lid, the latter has opened sufficiently far for the wind deflector plate, subject to the action of springs acting in the upward pivoting direction, to pivot upwards beyond the automobile roof without striking the slid lid.

Abstract: A multipart, telescopic shield for covering the lateral gap between the underside of a rigid sliding cover with which it is displaceable and the roof frame of a roof of a motor vehicle. The sliding cover has front and rear guide shoes which are guided on rails arranged laterally on the roof frame. In addition, the sliding cover has a water deflector which is displaceable therewith to underpin the rear edge gap between the cover and the fixed vehicle roof. The water deflector is also guided along the guide rail by guide shoes. The water deflector is connected to the cover by arms which are constructed as a shield.

Abstract: In a sliding-lifting roof for an automobile, of which a sliding lid can be actuated, by the engagement of guide pins, mounted on rear, driven sliding shoes, in guide blocks fixed to the sliding lid, the sliding lid is covered below by a liner, connected with it for common displacement, which liner is formed of a non-pivotal lower part and a flap component hinged thereto. The flap component is, in lifting movements and pivoting-in movements of the sliding lid, pivoted correspondingly, but in the starting phase of the lifting movement with lead compared with the sliding lid, as a result of control ramps fitted to the liner lower part and of lifting levers, pivotally connected to the rear sliding shoes and co-operating with the ramps. As a result, when only a small lifting angle of the sliding lid takes place, a sufficiently wide ventilation gap is obtained between the liner lower part and the liner flap.

Abstract: In a rigid lid for an automobile roof which, in its closed position, sealingly closes a roof opening out of which it can be displaced to at least partly expose it, a translucent or transparent lid plate is carried by an inner frame placed beneath it in its edge region, which inner frame projects beyond the edge of the lid plate and terminates there in a raised rim, onto which an edge gap sealing strip is pushed. For achieving a low overall depth of the lid accompanied by simple assembly and dismantling, a clamping bar is fixed to the inner frame, with which clamping bar an upper border frame is releasably engaged, which border frame securely holds, on the one hand the sealing strip in a manner preventing stripping-off and on the other hand the lid plate with respect to the inner frame. A further simplification of dismantling is achieved, according to a second form of embodiment, in that the inner frame is connected to the upper edge frame releasably by fixing screws.

Abstract: In a rigid lid, associated with the roof opening of an automobile roof surface, in order to achieve low manufacturing tolerances at the lid external dimensions and to simplify manufacture of the lid, the lid plate and the reinforcing frame fitted below it have injection moulded around them a single-piece, peripheral plastics frame, which additionally constitutes an upper bordering frame and carries integrally formed fixing elements for an edge gap sealing member.

Abstract: In a sliding roof for automobiles, a sliding lid is secured against tearing out from the roof opening due to the high uplift forces acting on it at extremely high speeds of travel of the order of 300 km/h (186 m.p.h.), by a sealing profile strip, engaging beneath an edge flange of an automobile roof and secured against stripping off from the sliding lid by means of a holding frame. The sealing strip has two grooves, one engaging a downwardly-extending peripheral flange of the lid and the other engaging holding elements which extend substantially horizontally, spaced from, beneath and beyond the downwardly-extending flange.

Abstract: A clamping device, for use for example for clamping a tool or workpiece in position in a machine tool comprises a clamping anchor to which a clamping force is applied by a hydraulically operated cylinder. The device also includes a screw operated compensating or back-up unit which acts on the piston of the hydraulic cylinder. The compensating unit is driven by the same hydraulic system as the hydraulic cylinder and when the piston has been moved hydraulically to apply the clamping force to the anchor, a screw component of the compensating unit moves into engagement with the piston to lock the piston in position and maintain the clamping force even if the hydraulic pressure on the piston is then released.

Abstract: A cable guide for automobile sliding roofs having two lateral guide components (9), which together displaceably guide the guide shoes (7,8) of a sliding panel, and one forward guide component (10), adjoining the two lateral guide components. To achieve a simplified construction which can be manufactured and installed at low cost while simultaneously avoiding butt joints in the region of the cable guide channels which are (19,10) continuous through all three guide components, all three guide components (9,10) have an identical cross-sectional shape and are formed from a single-piece guide frame (11).

Abstract: A clamping device which is arranged to clamp a workpiece to a table or stand, and which does not obstruct the clamping region of the table or stand, has a fluid pressure-loaded clamping piston slidably mounted in a main housing with toggle levers on either side thereof bearing against oppositely situated saddle bearings at the sides of the housing. The toggle levers are moved by the clamping piston between an inclined position and an extended position and load a clamping or pulling anchor which is mounted on the housing. The clamping or pulling anchor is pivotally mounted on a clamping lever so that it can swing through a maximum of 180.degree. from a clamping position into a release position in which it is well clear of the workpiece. The anchor is fitted onto a bearing pin, which is disposed in an end, which projects from the housing, of the clamping lever which is pivotally mounted in the housing.

Abstract: In a method and apparatus for the height adjustment and installation of a slidable and/or raising, rigid roof member, to be built into a roof opening of an automobile roof, which roof member, after its height adjustment, is screwed to elements of the roof construction which do not participate in the height adjustment movement, a rapid and reliable height adjustment and installation are achieved in that, first the actuating elements are moved into the closed position, whereupon the roof member is inserted, by means of an installation template engaging over the roof opening and to be positioned onto the automobile roof, into the roof opening in a defined position with pressing of the roof member front edge onto the associated roof opening edge and simultaneous height adjustment, whereafter finally the screwing of the roof member in this position takes place.

Abstract: A quick-acting clamping device for clamping tools or workpieces in machine tools comprises a piston which is slidable transversely to the clamping direction and which acts on a toggle mechanism which in turn moves a clamping piece. A pressure plate upon which the toggle mechanism acts is displaceable in the clamping direction in a housing which contains the transverse piston. The fluid under pressure which acts on the transverse piston to activate the toggle mechanism also acts directly on the pressure plate to assist in clamping. Because of the assisting force produced by the pressure plate it is possible for the transverse piston to move the members of the toggle mechanism from starting positions in which they lie at large angles to the clamping direction, that is with a big angular displacement from their dead-center position, in which they initially exert only a small force on the clamping piece.

Abstract: A bracing device for machine tools which is formed with a compensation unit having a housing with threaded pins arranged in the housing rotatably displaceable relative thereto with a hydraulic rotary drive being provided for actuating the threaded pins.

Abstract: In a pane guide for a sliding window capable of being lowered into the window shaft (8) of an automobile, the windowpane (1) is laterally guided on windowframe components (4,5), in which back-cut guide channels (18,18') are provided, in which slide elements (23,23') are displaceably guided. The slide elements are connected with the windowpane (1), covering the windowframe components on the outer side of the vehicle, by carrier elements (19 to 22). Due to the mounting of the windowpane outside the windowframe, a projectionless lateral glazing of an automobile is made possible. At the lower end of at least one of the lateral windowframe components (4,5), the guide tube (11, 11') of a cable/tube window winder is connected in alignment with the guide channel (18, 18'). The threaded cable (12, 12') of the window winder extends into the guide channel (18, 18') and is fixed at least to one of the slide elements (19 to 22) situated therein.
