Description

(1) The invention will be explained in greater detail below using a drawing representing only one exemplary embodiment.

(2) FIG. 1 shows a schematic view of a rear flap in an overview along with the operating arrangement according to the invention as well as the motor vehicle latches provided for in this regard,

(3) FIG. 2 shows the operating arrangement in the “unlocked” position reduced to the components essential to the invention and

(4) FIG. 3 shows the subject matter according to FIG. 2 in the “locked” position.

(5) In FIG. 1 is represented generally and in an overview an operating arrangement on the rear flap 1. The rear flap 1 is part of a so-called “pick-up” and is, for that purpose, attached rotatably to an open cargo area of said motor vehicle with bilateral lower bearing pins 2. To lock the rear flap 1 across from the motor vehicle body, the rear flap 1 is provided, according to the exemplary embodiment, with two motor vehicle latches 3 located across from one another and only suggested in FIG. 1. The two motor vehicle latches 3 are placed at a distance from one another and are located across from one another according to the exemplary embodiment. The rear flap 1 across from the motor vehicle body is locked and unlocked with the two motor vehicle latches 3, which are designed as motor vehicle flap latches 3.

(6) The operating arrangement comprises a drive train with an electric motor 9 and a transmission arrangement 10 acted upon by the electric motor 9 with a screw spindle 15 and a threaded member 11, a lever arrangement interacting with the drive train and two means of transmission 7, each of which act upon one of the two motor vehicle latches 3. The lever arrangement has an operating lever 5 to act upon the means of transmission 7 and a locking lever 6, which blocks the operating lever at least when it is in the “locked” position.

(7) When the operating arrangement is in the “unlocked” position, the rear flap 1 can be opened with a handle 4. For that purpose, the handle 4 may be attached rotatably to the rear flap 1. A corresponding swiveling motion of the handle 4 around a horizontal axis, suggested in FIG. 1, then leads to the operating arrangement opening the motor vehicle latches 3 through the two means of transmission 7 attached to the lever arrangement. The two means of transmission 7 are, according to the exemplary embodiment but not restrictively, transmission rods. In principle, other means of transmission can also be used at this site, e.g. cables and other combinations. In any case, the action upon the handle 4, according to the swiveling motion represented and suggested in FIG. 1, ensures that the operating lever 5 performs a clockwise motion around its axis, also suggested in FIG. 1.

(8) Since the two means of transmission or transmission rods 7 are each attached eccentrically to the operating lever 5 according to the exemplary embodiment, this clockwise motion of the operating lever 5, when the operating arrangement is in the “unlocked” position, leads to the means of transmission or transmission rods 7 being acted upon with a pulling motion also suggested in FIG. 1. The pulling motion of the means of transmission or transmission rods 7, visualized in FIG. 1 with an arrow, leads to the correspondingly acted upon motor vehicle latch 3 being opened. In this exemplary embodiment this is because the pulling motion of the means of transmission 7 leads to a pawl, as a component of a locking mechanism constituted of a catch and pawl, being raised from its resting interaction with the catch. As a result thereof, the catch of the motor vehicle latch 3 comes free and thus so does the rear flap 1 of each locking pin 8 on the motor vehicle body also suggested in FIG. 1. The rear flap 1 can thus be swung up or down.

(9) The drive train, which can be seen best in FIGS. 2 and 3, is designed, according to the exemplary embodiment, as a linear actuator or a linearly operating actuator. Rotating motions of the electric motor 9 and thus of the transmission arrangement 10 rotate the screw spindle 15. A rotation of the screw spindle 15 is converted, via interaction with a thread on the threaded member 11, into a linear actuation of the screw spindle 15 on the output side as a component of the drive train 9, 10, 11, which are suggested in FIG. 2 by a double arrow. The linear actuations of the screw spindle 15 of the drive train located on the output side are transformed into rotating motions of the locking lever 6. Furthermore, the screw spindle 15 is connected to the locking lever 6 with a rotating joint. Moreover, the locking lever 6 is also attached rotatably to a base plate 12, as is the operating lever 5.

(10) According to the exemplary embodiment, both levers 5, 6 are detachably coupled with a ratchet connection or ratchet rotating connection to the base plate 12 in question, which, in the exemplary embodiment, is or can be manufactured using plastic, i.e. the two levers 5, 6 can be coupled to the base plate 12 in question with a combination of inserting, locking and, if necessary, rotating motions. With the help of FIGS. 2 and 3, it can be recognized that the two means of transmission 7 or transmission rods are attached to the operating lever 5 with jointed insertion connections, eccentrically in comparison with its axis of rotation. Moreover, according to the exemplary embodiment, the operating lever 5 is designed with a boom 5b to which is attached a further transmission element 13. According to the exemplary embodiment, the transmission element 13 is also a rod or transmission rod.

(11) Pivoting motions of the handle 4 mounted rotatably on the rear flap 1 are finally performed on the operating lever 5 with the transmission element 13. Pivoting motions of the handle 4 around its axis of rotation, suggested in FIG. 1 with an arrow motion, parallel to the rear flap 1 leads, according to FIG. 2, to the transmission element 13 or the transmission rod there being moved in the indicated arrow direction downwards when in the “unlocked” position. This results in the operating lever 5 performing a clockwise motion also suggested in FIG. 2 around its axis.

(12) In the “unlocked” position of the operating arrangement represented in FIG. 2, the operating lever 5 can perform the clockwise motion around its axis initiated with the help of the handle 4, because the operating lever 5 is free of the locking lever 6 when it is in the “unlocked” position of the operating arrangement. As a result of the clockwise motion of the operating lever 5 corresponding to the “unlocked” representation in FIG. 2, the two means of transmission 7 or transmission rods are each acted upon with a pull in the arrow direction suggested in FIG. 1 and ensure, at the end in the attached motor vehicle latches, that the respective pawl is raised from its interaction with the catch, for example. This has already been explained above. As a result thereof, the concerned motor vehicle latch 3 releases the locking bolt or locking pin 8 on the motor vehicle body and thus the rear flap 1 across from the motor vehicle body can be up or down.

(13) To move the operating arrangement into the “locked” position shown in FIG. 3, on the other hand, first the drive train, starting in the “unlocked” position in FIG. 2, must be acted upon so that the screw spindle 15 is moved “downwards.” As a result of the downward motion of the screw spindle 15, the locking lever 6, attached to the screw spindle 15 with a pivot joint, is moved counterclockwise around its axis, starting in the position corresponding to the representation in FIG. 2. The result of this is that the locking lever 6 blocks the operating lever 5 that acts upon the respective means of transmission 7 when the operating arrangement is in a “locked” position.

(14) For that purpose, both the locking lever 6 and the operating lever 5 each feature the detail of having blockade contours 6a and 5a, respectively. The concerned blockade contours 6a and 5a are each a right angle contour. Moreover, the design is such that the two blockade contours 5a, 6a correspond to one another, i.e. in the “locked” position corresponding to the representation in FIG. 3, have a force-locking connection to one another. In fact, the two blockade contours 5a, 6a even interlock solidly and exceedingly form-fittingly. As a result thereof, the operating lever 5, starting in the “locked” position corresponding to FIG. 3, cannot (any longer) perform a clockwise motion around its axis to open the two motor vehicle latches 3. To that effect, the handle 4 is also blocked according to the exemplary embodiment. In principle, the handle 4 can also be designed so that an idle stroke occurs when the operating arrangement is in the “locked” position.

(15) To act upon the locking unit, this may be attached to a controller 14 only suggested in FIG. 2. The controller 14 is, in turn, controlled with, for example, a switch provided within the motor vehicle, a remote threaded or by other means so that the drive train 9, 10, 11 is acted upon over the controller 14 to assume the desired “unlocked” or “locked” position. The drive train is accommodated and kept in a housing-like molding of the base plate. Individual housing is thus unnecessary.

(16) As previously explained, the base plate 12 can be advantageously manufactured of plastic. This is similar for the two levers 5, 6. With a base plate 12 design using plastic, it is possible, moreover, to create individual openings or a housing replica 12′ in or on this base plate 12, serving to accommodate the drive train. With this housing replica 12′, the base plate 12 is also capable and designed to mount the drive train. The two means of transmission or transmission rods 7, on the other hand, are also designed as metal rods, just like the transmission element or the transmission rod 13. The means of transport 7 in question and also the transmission element 13 are each hooked in the operating lever 5, which thus not only ensures the mechanical coupling with the handle 4 and is designed for this purpose, but at the same time acts upon the two motor vehicle latches 3 placed at a distance from one another over the means of transmission or the transmission rods 7.
