Definitions

  • the invention relates to a device for moving the detachable roof of a passenger car between its closed, normal position and the storage space in the rear of the vehicle, the latter being closable with a rear compartment cover that contains the trunk lid and laterally is essential ice to the door cutouts of the body, the movement of the rear compartment cover both as also the roof is made by a common drive, opening and closing of the cover ia necessary time offset for moving the roof occurs in the latter on guide rails reaching into the corner space can be moved by means of a pulling device acting in both sightings and the pulling device consists of flexible parts running in guideways consists.
  • a particularly well-known form of these flexible parts consists of a rope partially made of steel wires and a wire helix running around the rope, non-positively connected to its surface, the slope of which is regular and obsessive within narrow tolerances, so that the gaps between adjacent turns are appropriately shaped Can engage teeth of a drive gear.
  • GB Spec. 414,968 describes an embodiment in which the pulling device moving the roof, which in itself shows an extraordinarily complex construction, acts on the lower edge of the roof rear wall in the middle thereof.
  • the guidance is carried out on both sides and in the middle by means of rollers, each of which engages in pairs around the associated guide tan.
  • the roof is moved by means of elaborate lever constructions which, apart from other disadvantages, would not permit operation, even reasonably safe, because of the poor lateral stability without additional measures that go well beyond the given gauges.
  • GB Spec. 455, 769 and CH-PS 256, 152 describe constructions in which the vehicle upper part consists of at least two parts which can be moved or swiveled relative to one another. They are not stowed in a covered rear area, since the roof part covers the rear roof wall and the otherwise open rear part of the vehicle.
  • BE-PS 493, 26 ⁇ and FR-PS 1, 086, 921 are mixed constructions. Both have both slide rails and numerous z. T. multi-part Hehel, locks and the like. In some cases, the interaction of the individual elements is quite complicated and accordingly requires complicated constructions.
  • the invention is based on the technical problem of the devices which have become known in the prior art for moving a vehicle to improve the lower part of the detachable fixed roof or hard tops in such a way that simple, functionally reliable operation is possible, the necessary technical effort is justifiable and the application to most common limousines and sports cars without any fundamental structural changes, apart from the necessary separation between the top and bottom of the vehicle lower part, becomes possible.
  • a device of the type described at the outset which is distinguished in that the flexible shafts arranged in a manner known per se for practically strain-free absorption of tensile forces are arranged on either side of the vehicle in one of two curved guideways are both congruent in shape and each have a high, narrow, closed loop at the front end of the arch, both of which are also identical, the flexible shafts at their rear ends are connected to the roof guided in guide rails via articulated drivers, while their front ends are each connected in the closed loop running ends, each with a lever of a known type for moving the rear compartment cover, are each individually connected and can be driven by a common drive, not shown, via two drive wheels each assigned to one side, to continue known limit switches and interlocks are provided between the front roof edge and the frame of the windshield.
  • a manually operable locking of the rear compartment cover can advantageously be connected to a safety shutdown of the entire device.
  • the flexible shafts are steel cables which are known per se and which have a helical wire winding which is connected to the cable in a force-locking manner and enables the positive engagement of corresponding drives. They are advantageously guided in pipes which have a slot parallel to the pipe axis at the top or on one side for carrying out the cable connections.
  • These tubes can advantageously consist of an abrasion-resistant, rigid plastic with a low coefficient of friction or of metal tubes.
  • the slotted pipes made of plastic can be inserted into slotted metal pipes and / or arranged in pairs on each side of the vehicle with mutually pointing, i.e. internal, slits.
  • the unavoidable sliding or separating points between the roof and the body lower part are sealed in a conventional manner by overlapping rubber lips or the like. Water that penetrates through undidnt places is usefully combined in collecting troughs and - as is known per se - led under the vehicle through suitable processes.
  • a safety clutch can advantageously be provided between the drive motor and the movement mechanism. If, for example, the luggage and the area of the cable guides and guide rails are not effectively separated from one another in the rear area, which is easily possible by suitable means known per se, sudden driving maneuvers such as sharp braking, abrupt avoidance, etc. may result in the following moves a piece of luggage in such a way that the slip clutch responds and the roof can no longer be moved by the motor drive. Not only in such cases, but in general, the possibility of moving the mechanism "by hand" with the drive switched off and expressed has proven to be an important aid, especially since, for example, even if the drive fails for any reason, the locking of the vehicle by extending and attaching the roof is still possible. The unintentional sliding of the luggage in the trunk can be effectively prevented by suitably shielding the mechanism against the luggage space, which can be done in various ways within the framework of known measures.
  • the roof Due to the pull on the roof of the rear driver, the roof is raised at the beginning of the retracting process or until just before touchdown when extending so that it is practically only supported in the running rails, which is why the friction between the roof and the lower part of the vehicle Minimum is reduced.
  • the for Moving the roof required forces are limited to a minimum.
  • the solution to the technical problem according to the invention has proven to be extremely reliable and problem-free in numerous operating hours.
  • the extension or retraction process takes place within a few seconds. It has been found that the mechanism can be actuated at any time not only when the vehicle is stationary, but also when driving slowly, which is of great importance, for example in the event of sudden precipitation, particularly if this is during driving on a motorway or in another situation in which stopping is not possible should happen.

Abstract

Le dispositif, servant a amener le toit stable (1) d'un vehicule automobile, separe de la partie inferieure du vehicule, dans un coffre arriere ferme (4), consiste en un couvercle arriere (3') pivotant vers le haut autour d'un axe horizontal situe a l'arriere du vehicule, en deux rails de guidage (5) du toit s'etendent depuis l'extremite arriere du toit jusque dans le coffre et d'une glissiere incurvee en forme d'arc pour chaque cable moteur (arbre flexible) (11) coulissant dans celle-ci. A l'extremite anterieure des arcs respectifs, les glissieres forment une boucle fermee, allongee et etroite, les arcs et les boucles etant separes par une roue d'engrenage d'entrainement du cable situee dans un boitier ferme. Les cables sont de preference des cables en acier sur lesquels est accrochee par adherence une helice en fil d'acier ayant un pas donne. Les roues d'entrainement sont en prise avec cette helice. Les glissieres consistent en des tubes rigides presentant une fente sur la partie superieure ou sur le cote. A travers ces fentes et a l'aide de moyens appropries, les cables sont relies, par leur extremite posterieure, a la partie posterieure du toit et, par leur extremite anterieure, a des leviers pour l'actionnement du couvercle. Le toit est assure dans ses deux positions extremes a l'aide de dispositifs de verrouillage. Le deplacement du toit est possible a l'arret ou lorsque le vehicule roule a faible vitesse.
