Covering device

Abstract

A covering device for a storage compartment of a vehicle includes a cover that is slidably mounted for movement between a closed position and an open position. An actuating element is arranged on the cover for manually actuating the cover to be moved along a movement direction between the closed position and the open position. In the closed position a latching part of the cover engages a projection to lock the cover in the closed position. A spring bias is provided to bias the latching part of the cover into engagement with the projection when the cover is in the closed position. The latching part and the projection are engaged in such a way that a locking action of the latching part on the projection is released by manual actuation of the actuating element in the movement direction.

DETAILED DESCRIPTION

(7) The covering device according to the invention which is shown in the figures comprises a cover 10 which is configured as a roller blind in the example which is shown. The cover 10 can be displaced between a closed position (shown in FIGS. 1 and 2), in which it closes a compartment which is delimited by way of a housing 12, for example a storage compartment of a vehicle, and an open position (not shown in the figures), in which the cover 10 opens the compartment, along the linear movement direction which is shown at the designation 14 in FIG. 1 in the example which is shown. Bearing grooves 16 which lie opposite one another and preferably have a rectangular cross section are provided to guide the cover 10. On its opposite sides, the cover 10 has a plurality of cylindrical bearing journals 18 which are guided in the bearing grooves 16 during the movement of the cover 10 between its open position and its closed position. In order to actuate the cover 10, the latter has an actuating projection 20 which forms an actuating handle in the present case and is arranged in the region of the free end of said cover 10, the left hand end of said cover 10 in FIGS. 1 and 2, on the upper side which faces away from the compartment. Via said actuating projection 20, the cover 10 can be displaced manually between the closed position and the open position. Moreover, the cover 10 comprises a series of roller blind slats 22. Here, a gripping slat 24 of the roller blind, which gripping slat 24 supports the actuating projection 20, is of somewhat larger configuration than the remaining slats 22. At its free end, moreover, the cover 10 has in each case one latching projection 26 on its opposite sides, which latching projection 26 is configured as latching hook 26 in the example which is shown. Moreover, in each case one locking projection 30 (a wedge-shaped locking ramp 30 in the present case) is arranged on the lower side wall 28 (in the mounted state) of the bearing grooves 16. The locking ramp 30 has a ramp face 32 which rises in the movement direction of the cover 10 out of the open position into its closed position, that is to say to the left in FIG. 2. The end of the rising ramp face 32 is adjoined by a ramp wall 34. In the example which is shown, both the ramp faces 32 and the ramp walls 34 lie in each case in one plane. Otherwise, the bearing grooves 16 including the locking ramps 30 are of identical configuration with respect to one another, merely in a flipped manner about a longitudinal center plane.

(8) As can be seen, in particular, in FIG. 2, the latching projections 26 engage behind the locking ramps 30 or their ramp walls 34 in the closed position which is shown in FIG. 2. In said closed position, the cover 10 is locked securely against a displacement into the open position, for example in the case of a force which occurs in the case of a crash of the vehicle along the movement direction 14 (to the right in FIG. 2). Moreover, it can be seen in FIGS. 2 and 4 that the upper edge 36 of the ramp wall 34 lies behind the lower edge 38 of the ramp wall 34 as viewed in the movement direction 14 of the cover 10 out of the open position into the closed position (that is to say from the right to the left in FIG. 2). Therefore, the ramp wall 34 is tilted in the movement direction 14 of the cover 10 into the closed position into a plane which is illustrated at the designation 40 in FIG. 2. Said plane 40, in which the ramp wall 34 lies, encloses an acute angle 42 with the movement direction 14, in particular a straight line which emanates, starting from the upper edge 36, in the movement direction 14 of the cover 10 into the open position (that is to say to the right in FIG. 2). With respect to a plane 44 which lies perpendicularly on the movement direction 14, the ramp wall 34 encloses a negative angle 46. Moreover, the ramp wall 34 encloses an acute angle with the side wall 28, as viewed counter to the clockwise direction starting from the upper edge 36 in FIG. 2. As a result of said arrangement of the ramp wall 34, a release of the locking action in the case of an occurrence of a force which acts perpendicularly with respect to the movement direction 14 (upward in FIG. 2) in the case of a crash is also prevented in the closed position which is shown in FIG. 2.

(9) In order to open the cover 10 from the closed position which is shown in FIG. 2, an opening force is exerted manually on the actuating projection 20 in the movement direction 14, as shown in FIG. 2 at the arrow 48. On account of the lever effect, this leads to a torque on the cover 10, as illustrated by way of the arrow 50 in FIG. 2. As a result, the latching projections 26 are released from the engagement with the locking ramps 30, slight pivoting of the cover 10 occurring, for example about the pivot axis which is shown at the designation 52 in FIG. 2. Pivoting can of course also take place about another pivot axis, for example formed by way of an integral hinge or roller blind hinge which is formed by way of the cover 10. The cover 10 can then be displaced into the open position (to the right in FIG. 2) by way of further exertion of a force in the direction of the arrow 48 in FIG. 2. Here, no other exertion of force by way of the operator is required than along the arrow 48. Solely said exertion of force leads automatically to pivoting of the cover 10 and therefore an unlocking action.

(10) An elastic spring arm 54 can also be seen in FIG. 4, which elastic spring arm 54 presses the latching projections 26 against the side wall 28 of the bearing grooves 16 in the closed position (that is to say downward in FIGS. 2 and 4). The unlocking of the cover 10, in particular the pivoting about the pivot axis 52, therefore takes place under elastic deformation of the spring arms 54 (upward in FIG. 4), counter to the spring prestress of the spring arms 54. The force which is required for the unlocking action can be set flexibly in the desired way by way of the spring arms 54, to be precise in a merely slightly dependent manner on the material selection, the thickness and the temperature of the cover 10. Therefore, the material and the geometry of the cover 10 can fundamentally be selected freely. It is thus conceivable, for example, that the cover 10 has a textile or leather covering or a metal component which is applied to the slats 22 of the cover 10.

(11) In order to move the cover 10 back into the closed position, a force is exerted manually on the actuating projection 20 in the opposite direction to the arrow 48. When the locking ramps 30 are reached, the latching projections 26 then first of all slide over the ramp faces 32 before they engage behind the ramp walls 34 again in the closed position in the state which is shown in FIG. 2.
