The third guide portion 77 is groove-shaped and forms on the guide sleeve 68 a recess with an opening angle of 90 °. The third guide section 77 extends over the first guide section 73, wherein the second guide section 76 connects the first guide section 73 with the third guide section 77. The guide portions 73, 76, 77 form a C-shaped geometry. The third guide portion 77 is not necessarily parallel to the first guide portion 73, but obliquely to this. Alternatively, the third guide portion 77 can also run parallel to the first guide portion 73. In particular, the third guide section 77 extends downward from the second guide section 76 in the direction of the lower edge 75. The third guide section 77 can also run obliquely upward away from the first guide section 73. The third guide section 77 is adjoined by a fourth guide section 78 arranged below the third guide section 77 with respect to the lower edge 75.

The unlocking / locking device 67 further comprises a tubular handle or a control element 79. In the operating element 79, a rod-shaped actuating element 80 is received, which may also be tubular. At a first end portion 81 of the operating member 80, an operating knob 82 is provided, which is fixedly connected to the first end portion 81. Between the actuating knob 82 and a bearing disc 84 positioned on a shoulder 83 provided in the actuating element 80, a spring element 85, for example a compression spring, is provided. The spring member 85 biases the actuator 80 and the operating knob 82. The actuating button 82 can be displaced into the operating element ₇₉ against a spring force of the spring element 85 in a longitudinal direction L _{79 of} the unlocking / locking device 67. In a second end portion 86 of the actuating element 80, a bolt 87 is received. The longitudinal direction L ₇₉ is oriented perpendicular to the longitudinal direction L ₂₂ .

The actuating element 80 is fixedly connected to a housing 89 of the unlocking / locking device 67 at an end portion 88 facing away from the actuating knob 82. The housing 89 is firmly connected to the coupling device 59, in particular to the base section 60 of the coupling device 59, for example screwed by means of a screw 90. In the housing 89, a displaceable bolt or a locking element 91 is further added. For this purpose, the housing 89 has a tubular receiving portion 92, in which the locking element 91 in the longitudinal direction L _{79 is} axially displaceable. The locking element 91 is slidably mounted in the receiving portion 92. In the housing 89, a coupling element 93 is further provided for coupling the locking element 91 with the actuating element 80. The coupling element 93 is configured to implement a pressure movement on the actuating button 82 in a force acting on the locking element 91 tensile force, so that the locking element 91 in Direction is moved away from the guide sleeve 68. The coupling element 93 may be a cable, a transmission or, as in the Fig. 4 shown to be mounted at a pivot point 94 in the housing 89 rocker. The coupling between the locking element 91 and the actuating button 82 may also be realized pneumatically, hydraulically or electrically, for example by means of an electric actuator.

The lifting / panning device 22 includes a plurality of switches 95 to 97 that are contactable by a button 98 of the housing 89 for switching the same. For example, three or more than three, for example four, such switches 95 to 97 may be provided.

The hatch cover arrangement 4 has a laying element 99 for depositing the hatch cover 5. The depositing element 99 may be a U-shaped depositing plate having a base portion 100 and two side portions 101, 102 provided laterally on the base portion 100. The base portion 100 is fixedly connected to the roof portion 10, for example screwed. Furthermore, the hatch cover assembly 4 comprises a fixing or fixing device 103. The fixing device 103 comprises a handle 104 (FIG. Fig. 11 ), which is arranged in the interior I. With the aid of the handle 104, a fixing element 105, which is arranged above the frame portion 20, rotatable. With the help of the fixing device 103, the hatch cover 5 in the closed position and the ventilation position can be fixed in order to prevent chattering of the hatch cover 5, for example when driving on uneven terrain. The fixing device 103 further includes switches 106, 107 for detecting the position of the handle 104.

The functionality of the lifting / pivoting device 22 will be explained below. The Fig. 2 to 4 show the lifting / pivoting device 22 and the hatch cover 5 in the closed position. In the closed position, the sealing device 21 is pressed against the frame section 20, so that the hatch cover 5 is preferably closed in a gas-tight manner. The locking element 91 of the unlocking / locking device 67 is engaged in the first recess 69 of the tubular guide sleeve 68. The unlocking / locking device 67 is thus locked. One of an interface of the coupling device 59 and the housing 89 of the unlocking / locking device 67 formed guide member 108 which is associated with the guide slot 72, is located on a first side wall 109 of the first guide portion 73 of the slide guide 72. The button 98 activates the switches 95, 96 to detect the lock of the hatch cover 5. Fixing device 103 fixes corner section 9 of hatch cover 5. For this purpose, fixing element 105 may have a roller which rolls on corner section 9 during rotation of handle 104 for fixing hatch cover 5 in order to press sealing device 21.

To spend the hatch cover 5 from the closed position in the in the Fig. 7 and 8th shown ventilation position of the hatch cover 5 is first unlocked by means of the unlocking / locking device 67. For this purpose, a force acting against the spring force of the spring element 85 pressing force is applied to the actuating button 82. By the coupling of the actuating element 80 with the locking element 91 by means of the coupling element 93, the locking element 91 is pulled out of the first latching recess 69. Alternatively, the control element 79, the actuating button 82, the spring element 85 and the coupling element 93 can be dispensed with and the locking element 91, which can then be designed with a greater length extension, can be pulled out directly from the first recess 69. Once the locking member 91 is lifted out of the first recess 69, the coupling device 59 and the fixedly connected to this Unlocking / locking device 67 for unlocking the hatch cover 5 freely rotatable. A coupling of the coupling device 59 with the sleeve member 26 does not yet take place. That is, the sleeve member 26 is not rotated when rotating the coupling device 59.

With the aid of the operating element 79, the coupling device 59 and the unlocking / locking device 67 are rotatable in a first direction of rotation R ₁ until the guide element 108, which is guided on the upper side on the first guide section 73 of the guide link 72, in contact with the second guide section 76 of Slotted guide 72 device. A rotation angle by which the coupling device 59 and the unlocking / locking device 67 are rotated is 90 °. As soon as the guide element 108 contacts the second guide section 76 of the slide guide 72, the hatch cover 5 is unlocked and the guide element 108 is no longer guided by the first guide section 73 on the upper side and the coupling device 59 and the unlocking / locking device 67 are opposite in the longitudinal direction L ₂₂ the flange 23 slidably. Furthermore, during the rotation of the coupling device 59, the counter-engagement section 66 of the coupling device 59 engages in the engagement section 30 of the sleeve element 26 in a terminal manner. That is, the coupling device 59 is, when the guide member 108 is guided in the second guide portion 76, rotatably connected to the sleeve member 26 and the bolt 47 and the pillar member 31 rotatably connected to the hatch cover 5. Since the guide element 108 is guided on both sides by the second guide section 76, this is only vertically displaceable in the longitudinal direction L ₂₂ .

For lifting the hatch cover 5 in the ventilation position, the fixing device 103 is first actuated to release the corner portion 9 of the hatch cover 5. For this purpose, the handle 104 is rotated. Alternatively, the fixing device 103 may also be coupled to the unlocking / locking device 67, so that a separate actuation of the fixing device 103 is dispensable. Subsequently, the hatch cover 5 is raised by an upward pushing of the coupling device 59, wherein the spring device 54 supports the lifting movement by being supported with its first fastening section 55 via the bolt 47 on the sleeve element 26 held immovably in the flange element 23. Since the second attachment portion 56 of the spring means 54 is fixedly connected to the column member 31, this is displaced upwardly relative to the stationary sleeve member 26 in the longitudinal direction L ₂₂ , wherein the bearing elements 50, 51 of the bolt 47 in the axial displacement of the column member 31 in the in this provided slots 52, 53 are guided. In the ventilation position, the locking element 91 engages in the second recess 70 of the guide sleeve 68 a. Thus, the hatch cover 5 is locked in the ventilation position. As the Fig. 7 shows the hatch cover 5 can be fixed in the ventilation position by means of the fixing device 103 to prevent chattering of the hatch cover 5.

To bring the hatch cover 5 from the ventilation position to the open position, the locking element 91 is brought out of engagement with the second latching recess 70 by the application of a compressive force on the actuating button 82. With the aid of the operating element 79, which is rotatably connected to the hatch cover 5 via the housing 89, the coupling device 59, the sleeve element 26, the bolt 47 and the pillar element 31, the hatch cover 5 can be pivoted into the open position. In this case, the operating element 79 is pivoted in a second direction of rotation R ₂ , which differs from the first direction of rotation R ₁ . For example, the first direction of rotation R ₁ with a view from the interior I on the hatch cover 5 counterclockwise and the second direction of rotation R ₂ with a view from the interior I on the hatch cover 5 be oriented clockwise. When swiveling the hatch 5 slides the guide element 108 on the third guide portion 77 of the slide guide 72 from. The guide element 108 is guided on the upper side and underside in the third guide section 77. The third guide section 77 may be arranged obliquely relative to the first guide section 73 or run parallel thereto. In particular, the third guide section 77, starting from the second guide section 76, runs obliquely downward in the direction of the first guide section 73. As a result, the hatch cover 5 is lowered downwards in the direction of the laying element 99 during pivoting. In the event that the third guide portion 77 is parallel to the first guide portion 73, the hatch 5 is pivoted parallel to the roof portion 10. In the event that the third guide portion 77 extends obliquely upward with respect to the first guide portion 73, the hatch cover 5 is raised during pivoting thereof.

At the end of the rotational movement, the guide element 108 slides into the fourth guide section 78. As a result, the hatch cover 5 is deposited on the laying element 99 and comes to rest between the side sections 101, 102 thereof. As soon as the guide element 108 comes to rest in the fourth guide section 78, the locking element 91 engages in the third latching recess 71 of the guide sleeve 68. Thus, the unlocking / locking device 67 is locked again. The third latching recess 71 is arranged below the second latching recess 70 with respect to the first guide section 73. With the help of the button 98, the switches 96, 97 are actuated to detect the closed position of the hatch cover 5.

For reclosing the hatch cover 5, the locking element 91 is brought out of engagement with the third latching recess 71 by the application of a compressive force on the actuating button 82. Subsequently, the guide element 108 is supported by the spring device 54 from the fourth Guide section 78 lifted out. As a result, the hatch cover 5 is lifted out over the side sections 101, 102 of the laying element 99. The coupling device 59 and the unlocking / locking device 67 can then be rotated back by means of the operating element 79 in the first direction of rotation R ₁ . The hatch cover 5 pivots with it. In this case, the guide element 108 is guided by the third guide section 77. If the third guide portion 77 is optionally arranged obliquely, the hatch cover 5 is raised or lowered in the pivoting movement with respect to the roof portion 10.

With the control button 82 pressed further, the operating element 79 is displaced downwards relative to the roof section 10 against the spring force of the spring device 54, with the guide element 108 sliding through the second guide section 76 of the sliding guide 72. In this case, the hatch cover 5 is placed on the frame section 20. In a final position of the guide member 108 in the second guide portion 76 of the mating engagement portion 66 of the coupling device 59 is disengaged from the engagement portion 30 of the sleeve member 26 so that the coupling device 59 is decoupled from the sleeve member 26 and these are no longer rotatably connected to each other.

As soon as the guide element 108 is no longer axially guided by the second guide section 76 in the longitudinal direction L ₂₂ , the coupling device 59 is rotated in the direction of rotation R ₂ by means of the operating element 79, wherein the guide element 108 on the first guide section 73 in the direction of the side wall 109 slides. The sleeve member 26 which is rotatably connected to the hatch cover 5 is defined by the closed hatch cover 5. At the end portion 29 of the sleeve portion 26 adjacent to the engaging portion 30 is an inclined plane, in particular a guide track 110 (FIG. Fig. 5 ) provided on which the counter-engagement portion 66 slides during rotation of the coupling device 59 relative to the sleeve member 26. The guide track 110 is inclined so that upon rotation of the coupling device 59 it is displaced axially away from the end section 29 of the sleeve element 26 against the longitudinal direction L _{22 in} order to pull the hatch cover 5 onto the sealing device 21. As a result, the sealing device 21 is compressed during rotation of the coupling device 59, whereby the required contact pressure is always guaranteed.

The hatch cover assembly 4, the hatch cover 5 and the lifting / pivoting device 22 have the following advantages over known approaches. By the spring support by means of the spring means 54 and heavy hatch cover 5 can be opened comfortably. This also applies to extreme vehicle positions such as e.g. in strong terrain climbs. When using a gas spring as spring means 54 is to overcome their low progression when closing the hatch cover 5 only a small spring force. The lifting of the hatch cover 5 by means of the spring means 54 allows a much higher lift than e.g. when using a toggle mechanism or the like is possible. As a result, the hatch cover 5 can also be pivoted away via higher structures provided on the roof section 10, such as switches. The operation of the hatch cover 5 is completely over only one control element 79th

The unlocking, lifting or lowering and twisting of the hatch cover 5 via the control element 79. This allows a particularly simple and comfortable operation of the hatch cover 5. The lifting / pivoting device 22 allows the positioning of the hatch cover 5 in the ventilation position. Between the closed position and the open position several other positions for locking the hatch 5 can be set, which provides ventilation of the Allow vehicle 1 through a partially opened hatch cover 5. For this purpose, more than the three described locking recesses 69 to 71 may be provided on the guide sleeve 68. When using a gas spring as spring means 54, the lifting / pivoting device 22 can be used for various hatch cover 5 with different weights. This allows a versatile use of the lifting / pivoting device 22. It is advantageously a purely manual operation of the lifting / pivoting device 22 possible. To move the hatch cover 5 so no external power supply by electrical or hydraulic is required.

Although the present invention has been described with reference to embodiments, it is variously modifiable.
