The present invention relates to a housing and to a closing element for such housings which has a rollover safety device. Such housings are used for example as storage compartments in motor vehicles. If corresponding cavities have to be closed, they are closed with covers which are held in the closed state by means of closing elements. However the present invention may be used also in all other areas in which spaces are closed by covers.
The present invention describes a housing and a closing element for same, by means of which a housing cover can be securely closed. In particular, the locking of the housing cover in the locked state should be guaranteed.
According to the invention, the closing element has a covering frame which bears the individual parts of the closing element. This covering frame surrounds at least partially the opening of the housing to be closed. The covering frame can here be a separate element which is inserted into or attached to the housing; however it can also be embodied as one piece with the housing itself.
Arranged on this covering frame is at least one closing catch which is mounted so as to be displaceable. As the cover is closed, this closing catch is pressed to the side by the cover and then snaps into corresponding grooves in the cover in order to hold the cover in its closed position.
If the closing catch is resiliently mounted, such that it can be pressed in and moves itself back into its original position, a closure can be produced which can be closed and opened without active actuation, i.e. in which it is not necessary to open a lock in order to open the cover. This is achieved advantageously in that the closing catch has in its engagement area in each case lead-in slopes such that the closing cover presses onto the one lead-in slope and thus pushes the closing catch to the side when the lid is being closed. If the cover is being opened, it is sufficient to pull on it and the cover slides along the second lead-in slope on the other side of the closing catch and presses the closing catch back into its housing again such that the cover can be opened.
What is essential now is that in the closing element according to the invention a locking element is provided which locks at least one of the closing catches when the closing element is to be locked. The locking takes place here by means of a manual or motor drive, e.g. in connection with a vehicle's central locking system which actuates the locking element. In a first position, the locking element permits any otherwise possible movement of the closing catch such that the closing element is not locked. In a second position, the closing catch is locked such that it cannot be pushed back any more. In this case, therefore, it is no longer possible to pull open easily an already closed cover.
Advantageously, an unlocking element is furthermore provided, for example a release pin, which only allows the locking element to assume the second position when the cover is also actually closed. Such an unlocking element represents an independent aspect of the present invention. When the cover is open, this prevents the closing catches from being able to be pressed in any more by faulty actuation and thus the cover can also no longer be closed. The unlocking device is only triggered by closing the lid, and it then releases the locking element which for its part then assumes the second position and thus can lock the closing catches. The automatic consequence of this is that, in the case of a previously locked closing element, closing the cover is still easily possible, but then the cover also actually remains locked.
This device makes possible secure closing of the housing cover. When the vehicle is locked, this closing element guarantees the locking of the housing cover.
Advantageously two closing catches are fitted the one beside the other, thus the closing element is also suitable for flip-flap covers, i.e. covers which can be opened about three axes. In each case the two closing catches already secure the cover at two points whilst the cover itself only has to be rotatably attached at one point.
Crucial about the present invention is furthermore the fact that a safety device is provided which, in the event of the action of high forces or great acceleration, locks the closing catch or the plurality of closing catches and thus, e.g. in the case of a vehicle overturning or having an accident, locks the closing catch, independently of whether the locking element has already locked one of the closing catches or not, i.e. for example independently of the state of the vehicle's central locking system. This is particularly necessary if the cover can, as provided here, be opened without active actuation.
This rollover or crash safety device can be designed in such a way that a ball is mounted in a socket. Opposite the bearing is arranged a lever which can be moved by the ball. The lever has at one of its ends an element for engaging in a groove in the associated closing catch. For this purpose, the lever can be advantageously rotatably attached at a first end and have at its second end a pin which has teeth. If the closing catch also has teeth at the corresponding point, e.g. a toothed rod, the teeth of the lever can engage in the teeth of the closing catch and thus fix the closing catch when the lever is actuated by the ball.
In normal use of the vehicle, the ball remains lying in its socket and does not actuate the lever. In this manner, the closing catch is not fixed and can therefore be moved. Normal use of the cover is possible.
If the vehicle over turns or crashes, the ball is hurled out of the socket and presses on the opposite lever, such that one end of this lever engages in the corresponding teeth in the closing catch and locks said catch. Thus in the event of an accident, for example, this causes the cover not to be able to open.
What is advantageous about the present invention, therefore, is that opening of the cover is prevented in the event of the vehicle overturning or having an accident.
Furthermore, simple mounting of the individual closing parts or of the closing element is made possible. The covering frame, on which the additional elements of the closing element are arranged, makes possible tolerance compensation between the housing and the cover during assembly.
Finally, any faulty actuation of the closing element is provided by the closing mechanism described here.
In what follows, an example of a closing element according to the invention will be described, the figures showing:
Here and in what follows, identical and similar reference numerals are used for identical and similar elements, such that in some cases their description is not repeated in connection with the subsequent figures.
On the other side of the fixing rail 2 are arranged housings 4a and 4b for the closing catches 3a,3b. Above the closing catches 3a and 3b extends from one of the closing catches to the other a stay bar 5 which runs in grooves 11a, 11b arranged in the housings 4a, 4b. This stay bar 5 has two downwardly protruding engagement elements 6a, 6b which are arranged adjacent to the closing catches 3a and 3b.
The stay bar is moved to and fro between two positions by an electric drive 7 which is controlled by the vehicle's central locking system, via drivers 8 moved by said system. The drive 7 is here arranged in a housing 19 which forms part of the closing element. Two springs 9a and 9b are suspended in the drivers 8 and extend in each case to the side of the drivers in the direction of movement of the stay bar 5 and are suspended in two receivers 10a and 10b for the springs, which are embodied as one piece with the stay bar. If the driver 8 is now moved to the left by the motor 7, the stay bar also moves towards the left into a first position. In this position, the engagement elements 6a and 6b are disengaged to the maximum extent, such that they do not come into engagement with grooves 25a, 25b (see
The function of the release pin 12, which plays a role here, is described in more detail further on.
Furthermore in the region of the closing catch 3 a rollover and crash locking device 17 is arranged on the closing element by means of a mounting element 18. This rollover safety device 17 is also described in detail further on.
As can be clearly recognised, the closing catches 3a and 3b have two slopes 20a, 20b or 21a, 21b respectively. These lead-in slopes extend at various angles. A cover which is to be closed, moves down from above towards the closing catches 3a and 3b and presses on the flatter lead-in slopes 21a, 21b. This causes the closing catches 3a, 3b to be pressed, perpendicularly with respect to the plane of the drawing, backwards into their housing 4a, 4b, such that the cover can be closed. For opening the cover, it is merely necessary to pull on it since it then presses on the lower, steeper slopes 20a, 20b and also presses the closing catches 3a and 3b backwards, perpendicularly with respect to the plane of the drawing. In each case, there are to be provided in the cover two depressions or grooves corresponding to the closing catches 3a and 3b, into which grooves or depressions the closing catches 3a and 3b enter in the closed state, and thus can securely lock the cover.

It can be recognised here that the closing catches 3a and 3b are guided inside their housings 4a and 4b by the corresponding walls of the housings 4a and 4b. The closing catches 3a and 3b have walls 24a or 24b respectively extending into the housings 4a and 4b. Furthermore, each closing catch 3a or 3b has a guide pin 27a or 27b which is supported by a spring 28a, 28b on a bearing 29a or 29b. This guarantees that the closing catches 3a and 3b normally always attempt to disengage from their housing in the direction of the opening. Complete disengagement of the closing catches 3a and 3b is prevented by the lateral flanges 26a, 26a′ or 26b, 26b′ which are designed as stops and which, when the closing catches 3a and 3b are disengaged to the maximum extent, come into engagement with projections in the wall of the housings 4a and 4b. The housing 4a or 4b has furthermore in each case an opening 16a or 16b through which the respective guide pin 27a or 27b can emerge when the closing catches are pressed out of the housing 4a or 4b respectively.
It can be furthermore recognised in this figure that the walls 24a and 24b′ each have a recess or grooves 25a or 25b respectively, in which the engagement elements 6a or 6b of the stay bar 5 engage when the stay bar 5 is in its second position, and thus can fix the closing catches 3a and 3b.
This is illustrated again more clearly in
It can also be recognised that the safety device 17 has a socket 30 which bears a ball. The ball is covered on its other side by a lever 32 which can also be extended socket-like in the region of the ball. This lever 32 is rotatably mounted by means of a swivel-joint 35 at one of its ends.
The socket therefore forms a lower part and the lever 32 an upper part for enclosing the ball. The lower part extends now on both sides of the socket 30 and forms at the mounted end of the lever 32 a receiver 36a for a spring, to which an appropriate receiver 36b on the mounted end of the lever 32 corresponds. These two receivers 36a and 36b provide the bearing for a spring which in the normal state presses the lever onto the ball. At the other end, the lever 32 is mounted by means of a guide pin 39 in a guide 38, which only permits a vertical movement of the lever in the direction of the closing catch 3a. This guide 38 forms part of the lower part of the ball receiver. At the same end of the lever 32, a pin 33 protrudes in the direction of the closing catch 3a and bears teeth at its free end. The closing catch 3a for its part has on its underside a series of teeth or tooth-like depressions 34 which corresponds to the teeth of the pin 33.
It should be emphasized here that as or instead of a pin 33, any type of element of any shape can be provided which is suitable on its upper side for engaging in corresponding recesses in the closing catch 3a.
In the event of an accident or the vehicle overturning, a strong force acts now on the ball such that the ball moves the lever 32 upwards against the force of the spring 37 and thus brings the pin 33 into engagement with the teeth 34 on the underside of the closing catch 3a. Thus during the accident the closing catch 3a is then locked such that a cover secured with the closing catch 3a cannot open.
