description

The invention relates to a closing device for containers with two Behälterelemen¬ th, which are movable relative to each other between an open position and a closed position, in particular for to be mounted on motor vehicles roof box with two Kof¬ ferelementen, namely a lower part and a lid.

Such a closing device is known from DE 43 40 083 C2. The lid is pivotable relative to the lower part by means of hinges about two parallel axes, wherein the hinge axis are each arranged on a longitudinal side of the case. The hinges each comprise a sleeve connected to the cover and a hinge pin connected to the lower part, the latter being axially adjustable along the hinge axis. The hinge pins of all hinges on one longitudinal side of the case are axially displaceable via a common actuating rod. The actuating rod can be actuated by means of a lock cylinder. Thus, on the one hand, the hinges serve to complete the roof box by moving the hinge pins axially into the sleeves. Furthermore, when the hinge pin is open, the roof box can be pivoted on one longitudinal side of the case and the closed position of the hinge pins of the other longitudinal side of the case around the hinge axis of the hinge pins located in the closed position.

However, it has been shown that the displacement of the actuating rod requires high actuating forces. In addition, the actuation rods tend to easily catch, in which case the actuation rods can hardly be released by means of the lock cylinder and then moved. Object of the present invention is to provide a closure device for suitcases, in which the actuating forces are reduced.

The object is achieved by a closure device for containers with two container elements which are movable relative to each other between an open position and a closed position, in particular for to be mounted on motor vehicles roof box with two case elements, namely lower part and lid

a rotating rod, which is rotatably fastened to a first of the two container elements about a rotational axis between a release position and a blocking position,

at least one closure part which can be fastened to a second of the two container elements and is movable therewith between the open position and the closed position and which has an opening through which the rotary rod is guided in the closed position of the closure part,

Actuating means for rotating the rotary bar,

- Wherein the rotary rod, at least in the region in which the rotary rod is passed through the opening in the closed position of the closure part, a ab¬ flattened profile with a wide and a narrow profile width, - wherein the closure part has an opening through which the rotary rod when moving the closure part passes into the closed position to intervene in the Durch¬ break, and

- The opening is narrower than the wide profile width and wider than the narrow profile width of the flattened profile of the rotary bar, solved.

Since the rotary rod only needs to be rotatably mounted, the operating forces are significantly reduced. Furthermore, pivot bearings are less prone to freeze.

So that engagement of the rotary rod in the opening of the closure part is possible only in the release position of the rotary bar, it is provided that in the closed position of the closure part, the rotary bar in the release position with the side of the narrow profile width and in the locked position with the side of the wide pro- Filbreite facing the opening.

Thus, the closure device can also serve as a hinge, it is provided that the opening is designed in the form of a bore. Thus, the closure parts can be pivoted about the rotary rod.

In the region of the flattened profile, the rotary bar is preferably provided with a rounded surface which, upon rotation of the rotary bar from the release position to the blocking position when the closure part is not fully in the closed position, supports the rotary bar against an edge of the opening allows the closure member to be pulled to the closed position.

The actuating means preferably have a slide, which is displaceably guided axially in the direction of a displacement axis transversely to the axis of rotation between a release position and a locking position and has a recess. On the rotary rod, a rotary member is rotatably fixed, on which a driver projects parallel to the axis of rotation of an end face of the rotary member and cooperates with the recess of the slider.

Thus, the axial displacement of the slider is converted into a rotational movement of the rotary rod.

The actuating means may further comprise a rotary actuator which engages with a spur gear toothing to a rack portion of the slider. The rotary actuator can be rotatable by means of a lock cylinder.

Preferably, the driver sits when moving the slide between the release position and an intermediate position in the direction of the displacement axis form-fitting manner in the recess. In the direction transverse to the displacement axis of the driver is arranged adjustable in the recess.

Furthermore, it can be provided that the recess and the driver are designed and arranged in such a way that by moving the slider out of the free space in the intermediate position, the rotary rod is rotated from the release position into the blocking position.

This is advantageous, in particular, in the case of a lock cylinder in the form of an exchange cylinder, since the changeover cylinder can be removed in an intermediate position between a release position and a blocking position and thus can be exchanged. In this intermediate position is thus ensured that the rotary rod has already reached the blocking position and opening of the lid is prevented.

In this case, it can further be provided that the driver is supported during displacement of the slide between the intermediate position and the blocking position against a Sperr¬ surface of the slider and a rotation of the rotary rod is prevented. Thus, an idle stroke of the slider is generated in which the rotary rod is not further rotated, however, is locked against rotation in the release position.

To ensure that the locking device can only be locked when the closure parts are in the closed position, it is provided that the driver is supported when moving the slider between the intermediate position and the locking position against a locking surface of the slider and a twist the rotary rod is prevented.

Here, in the closed position of the container elements, the securing element is held by the closure part in a release position.

For supporting the rotary rod bearing elements, each with a kreiszylindri¬'s bearing surface rotatably connected to the rotary rod, which are rotatably received in correspondingly shaped bearing shells.

A preferred embodiment is explained in more detail below with reference to the drawings.

FIG. 8 shows a cross section according to FIG. 8 with the closing device in the open position.

Figure 1 shows a perspective view of an interior view of a longitudinal side of a roof box. The roof box is formed by a first case element in the form of a lower part 1 and by a second case element in the form of a lid 2. On the inside of the lower part 1, a rotary rod 3 is rotatably supported by means of bearing elements 25 and a rotary member 8 about a rotation axis 4. On the lid 2, three closure parts 5 are attached. The rotary rod 3 and the closure parts 5 are, as will be explained in more detail below, designed such that in a release position of the rotary rod 3, the closure parts 5 can be moved away from the rotary bar 3, so that the lid 2 can be opened. In a blocking position of the rotary rod 3, the closure parts 5 can not move away from the rotary rod 3. be moved, but only be pivoted about the rotary rod 3. If, in this case, a closing device is located on the opposite longitudinal side of the case in the release position, the cover 2 can be opened, wherein it is pivoted about the rotation axis 4.

In Figures 2 and 3, the operation of the locking device is explained in more detail with reference to the components on the central closure member 5 according to FIG.

The rotary rod 3 has a substantially rectangular profile and thus has a long profile width and a narrow profile width. The closure part 5 is provided with an aperture 6, through which the rotary rod 3 is passed in the closed position shown in FIG. In order to be able to transfer the closure part 5 from the open position shown in FIG. 3 into the closed position shown in FIG. 2, the closure part 5 also has an opening 7 which is narrower than the long profile width and wider than the short profile width of the rotary bar 3. If the rotary rod 3 is rotated into the release position shown in Figure 3, in which the profile is arranged vertically and thus the short profile width of the opening 7 zuge¬ wandt, the latch 5 can be moved over the rotary rod 3 until the rotary rod 3 in the opening 6 is arranged. Thereafter, the rotary rod 3 can rotate in the blocking position shown in Figure 2, in which the profile is aligned horizontally, so that the long profile width of the rotary rod 3 of the opening 7 faces and the closure member 5 can not be moved away from the rotary rod 3, as the rotary rod 3 does not fit through the opening 7 in this position.

The aperture 6 is designed in the form of a through hole, so that in the blocking position of the rotary rod 3 shown in Figure 2, the closure member 5 can be pivoted about the axis of rotation 4.

In order to be able to rotate the rotary rod 3 between the locking position shown in FIG. 2 and the release position shown in FIG. 3, a rotary element 8 is provided that is connected in a rotationally fixed manner to the rotary rod 3. The rotary element 8 acts, as will be explained in the following, with a slider 9 which, between a blocking position represented in FIG. 2 and an axial release position in FIG along a displacement axis 24 is displaceable. By moving the Schie¬ bers 9, the rotary rod 3 is rotated. The slider 9 has a Zahnstangenab¬ section 10 which meshes with a rotary actuator 11 in the form of a spur toothed Zahn¬. The rotary actuator 11 can be rotated by means of a lock cylinder 12 in the form of an exchange cylinder, so that due to the rotation of the Schließzy¬ Linders 12 of the slider 9 is moved axially.

In the figures 4 to 6, the interaction of the slider 9 and the rotary member 8 is explained in more detail below.

The rotary member 8 has a mounting slot 13, with which it surrounds the Drehstan¬ ge 3. Inwardly directed projections 14 in the fastening slot 13 ensure that the rotary element 8 can be clipped onto the rotary rod 3. From an end face of the rotary member 8 is a driver 15 parallel to the axis of rotation 4. Furthermore, the rotary element 8 has a circular cylindrical Außenflä¬ surface as a bearing surface 16 which is rotatably mounted in a bearing shell 17. The bearing shell 17 is part of a housing 20 that can be fastened to the lower part 1 of the roof box. The bearing elements 25 are designed identically to the rotary element 8 and also mounted in bearing shells.

In the blocking position shown in Figure 4, the driver 15 is supported against a locking surface 18 of the slider 9 from. The rotary rod 3 can thus not be rotated from the blocking position shown in FIG. 4 into the release position shown in FIG. Furthermore, it is avoided by this arrangement that by unintentional loading of the rotary rod 3 in the direction of rotation, z. B. by slipped objects within the roof box, a force is exerted by the rotary rod 3 on the lock cylinder 12. This is achieved in particular by the carrier 15 being supported against the blocking surface 18, which is arranged parallel to the displacement axis 24. Thus, the slider 9 is not acted upon in the direction of the Verschie- bearse 24 with force and the lock cylinder 12 also remains without force.

By turning the lock cylinder 12 reaches an intermediate position of Slider 9, the intermediate position shown in Figure 5. In this position, the driver 15 is located in a recess 19 in the form of a groove of the slider 9. By further rotation of the lock cylinder 12 in the Frei¬ gabeposition shown in Figure 6, the driver 15 is completely in the recess 19 recorded and vertically after pulled down so that the rotary member 8 and thus the rotary rod 3 are rotated to the release position. Conversely, by turning the lock cylinder 12 and thus by displacing the slide 9, starting from the release position shown in FIG. 6, into the closing position shown in FIG. 4, the rotary element 8 and thus the rotary bar 3 can be brought into the closed position.

The lock cylinder 12 is designed as a change cylinder and can be pulled out only in the intermediate position. To ensure that in this position in which the key can be removed, the locking device is already securely locked, is ensured by the arrangement described above already in the Zwischenstel¬ ment that the rotary rod 3 is in the closed position. Thus, it is also ensured that the roof box is completely locked when the key is incorrectly deducted when closing already in the Zwischeπstellung and not only in the locked position. A removal of the key in the release position is prevented.

Figures 7 and 8 show the outer closure members 5 shown in Figure 1, which are provided with a securing element 21. The securing element 21 is displaceably guided axially between a release position (FIG. 7) remote from the rotary rod 3 and a securing position (FIG. 8) close to the rotary rod 3. Here, the securing element 21 is acted upon by means of a compression spring 22 in the direction of the rotary rod 3 to force. The securing element 21 has a slot 23, with which it can embrace the rotary rod 3.

In the closed position shown in Figure 7, the closure member 5 is supported against the securing element 21 and pushes this vertically downwards in the remote from the rotary rod 3 position. If the rotary rod 3 is now transferred to the release position, the closure part 5 can be moved away from the rotary rod 3, then that the securing element 21 moves vertically upwards by the force of the compression spring 22 and encloses the rotary rod 3 with the slot 23. The slot 23 is designed to be as wide in width as the opening 7 of the closure part 5, so that the rotary bar 3 in the slot 23 of the securing element 21 can not be rotated. This prevents that in the open position of the roof box, the Schließvorrich¬ device can be completed.

Furthermore, in FIGS. 7 and 8, the rounded surface 26 of the rotating rod 3 can be seen. When the closure part 5 is not completely in the closed position, the rounded surface 26 makes it possible for the edge 28 of the rotating rod 3 opposite this surface 26 to bear against the edge 27 the opening 7 of the closure part 5 is supported, the closure part 5 moves into the closed position and makes it possible to rotate the rotation bar 3 without the rotation bar 3 colliding with the closure part 5 in the region of the rounded surface 26.
