Definitions

• the present invention relates to the loading compartment cover of motor vehicles, in particular the roller blinds, their fastening in the guide elements on the sides of the loading compartment and their removal from the loading compartment when the roller blind is wound up in its housing.
• Passenger vehicles often include a cover in the load compartment so that the interior of the load compartment and the objects carried therein cannot be seen from outside.
• Roll-up load compartment covers sometimes also called roller blinds, are often used. These covers usually comprise a housing with a winding device that is fixed behind the rear seats of the vehicle, with the rear end of the cover protruding. The cover is rolled out by pulling on the rear end, and the load compartment is covered by locking the rear end in the rear area of the load compartment.
• a guide for the rear end of the cover is provided in the side paneling of the load compartment, which defines the path of movement of the cover when it is rolled out.
• This document describes a roller blind cover whose rear end is attached laterally in grooves in the side wall paneling of the load compartment. At the rear end, the rear end of the cover can be removed from the grooves by pivoting.
• the guide for the rear end of the cover can be equipped with an electronic drive so that the cover can be rolled out and up via buttons or automatically, in particular depending on the closing and opening of the cargo compartment.
• Electrically operated cover is disclosed, for example, in document US10457124 B2.
• the cover, which can be operated manually or electrically and which is guided in the grooves in the side paneling of the cargo compartment, is described in document CZ 2021-300 A3.
• the disadvantages of the solutions known from the prior art are partially solved by the load compartment cover assembly.
• the assembly comprises a pair of guide rails for arrangement on the opposite side walls of the load compartment, a cover and a housing for storing the cover.
• the housing can be fastened between the side walls of the load compartment, in particular in openings or recesses in the paneling, and the cover is fastened to the housing with the front end and provided with a strut at the rear end.
• the front end and the rear end correspond, for example, to the standard direction of travel when the assembly is arranged in the load compartment in the position to be used for the cover.
• the strut comprises a strut body and a guide element at each lateral end of the strut body, which is adapted in shape for sliding attachment in the guide rail and is slidably connected to the strut body at a closed interval.
• the strut contains at least one spring element to move the guide elements away from each other.
• the spring element pushes or pulls the guide element laterally from the opposite guide element, whereby the spring element can be common to both guides or each guide element can have its own spring element.
• the strut body advantageously runs through most of the width of the cover, the cover can be glued or welded to it, for example.
• the guide strips are advantageously delimited by the paneling. They advantageously run over most of the length of the loading space for which the assembly is intended.
• the strut body is at least partially designed as a shell, e.g. with a round cross-section.
• the shape adaptation of the guide element for the guide in the guide strip is advantageously achieved by forming their cross-sections in shapes that match one another, ie, for example, the guide and the guide element or its part intended for arrangement in the strip have a rectangular shape, whereby the shape of the guide element is smaller at least by the play necessary for sliding without disproportionately high friction.
• the spring element preferably represents a spring which is clamped between the strut body and the guide element and is preferably arranged within the strut body, and the guide element also partially retracts into the body.
• the strut is telescopic, being spread by the spring element.
• the strut can also be used to guide the cover in guide rails that are not constantly spaced apart, for example when the side walls of the loading area approach each other at the front or rear.
• the strut does not fall out of the guide rails, nor does it press excessively on them, does not jam when sliding, etc.
• the cover can also have a non-constant width, so that when rolled out it covers the loading area and at least approximately copies the floor plan of the loading area and the shape of its walls.
• This strut can also be used for loading areas of different widths, even if the walls are parallel and the guide rails do not approach each other. It may not be necessary to produce different struts for the cover for different vehicle types.
• a part of the guide element can be pushed onto a section of the guide rail or panel in lateral Direction, ie on a vertical or nearly vertical surface, not only in the direction from above due to gravity on a horizontal or nearly horizontal surface. It may then be suitable, for example, to provide not only the corresponding nearly horizontal surface or surfaces, but also the nearly vertical contact surfaces between the guide element and the guide strip / covering with a sliding layer / to manufacture them from a suitable abrasion-resistant material.
• the housing can contain a winding device for winding up the cover.
• the winding device is advantageously spring-loaded so that winding is achieved by the force of the spring.
• the cover can then be rolled out manually or electrically.
• the housing preferably comprises an end piece at each lateral end which can be moved in the longitudinal direction of the housing and can be removably attached to the side wall of the loading area.
• the longitudinal direction of the housing corresponds to the transverse direction of the vehicle.
• the housing is then telescopic in the same direction as the strut.
• the housing also advantageously has at least one spring element to move the end pieces away from each other.
• the telescopic housing can also be implemented with just one movable end piece. Thanks to the movable end pieces, the housing can be inserted into and removed from the recesses without tools. These are preferably recesses in the paneling. To a certain extent, it is also possible to accommodate the same housing in loading areas of different widths.
• these recesses for the sinking in of the end pieces are part of the guide rails, in particular at the front end of the guide rails.
• the recesses for the sinking in of the end pieces are usually wider than the guide rails, since the housing is wider than the guide elements or strut, so that the recesses for the sinking in of the end pieces represent the widened end of the guide rails, in particular if the rails are grooves. This makes it possible to easily remove the strut from the guide rails through the recesses for the sinking in of the end piece when the cover is to be removed from the vehicle.
• the end piece then preferably has a recess on its rear side in order to accommodate at least part of the guide element in the housing.
• the rear side is therefore the side where the cover protrudes from the housing, ie the cover is rolled out/unfolded to the rear.
• the strut can thus be partially stowed in the housing or at least fixed to it, which makes handling with the cover removed easier.
• each end piece then preferably comprises a support element on its outside to support the guide element of the stiffener.
• the support element automatically ensures that the strut is released.
• the telescopic strut not only compensates for the differences in the distance between the guide rails, it also makes it easier to remove the cover from the vehicle.
• each of the guide rails has a groove comprising a horizontal groove section and a vertical groove section in cross-section perpendicular to the direction of displacement defined by the guide rail.
• the horizontal and vertical sections do not have to be exactly horizontal and vertical, they can deviate from the corresponding directions by up to 20° or up to 30°, for example. The transition between them can be sharp, rounded or kinked, in principle it is possible, for example, to use a groove with a circular cross-section.
• the vertical groove section and in particular the walls that delimit this groove cover the horizontal groove section from the side - as a result, the groove is essentially invisible to the user and thus does not disturb the interior design.
• this vertical groove section is open from below so that the guide element can be guided through.
• Each guide element comprises a horizontal element section and a vertical element section, which in turn can deviate from the exact horizontal or vertical direction, as described above for the sections of the groove.
• the guide element or its end has a shape that is complementary to the shape of the groove cross-section so that it can be guided therein.
• the horizontal element section is designed for sliding attachment in the horizontal groove section
• the vertical element section is adapted in terms of shape for the passage of the vertical groove section and for the connection of the horizontal element section to the strut body (sliding) through the open part of the vertical groove section.
• the groove is curved in cross-section so that it is not visible when the vehicle is viewed normally, and the guide element is curved accordingly so that it can be guided in the groove and at the same time connected to the strut.
• This improves the appearance of the vehicle, especially when the cover is rolled up or when the housing with the cover is not even fitted between the side walls.
• the design of the guide bar in the recess for the end piece to sink in, as described above, is particularly advantageous, since the strut can be easily lifted out of the loading space walls despite the groove being covered by the vertical section.
• the sliding connection of the guide elements to the strut body is advantageously ensured by the strut body having an opening for the element on each side, in which part of the guide element and at least part of the spring element are arranged in a sliding manner.
• the spring is thus hidden from dirt or damage, and the telescopic strut is also structurally relatively simple and reliable.
• an opening can be formed in the guide elements in order to insert the strut body with the spring element into this opening.
• the end pieces can be designed in a similar way.
• the sliding connection between the guide elements and the strut body and/or between the end pieces and the housing or the middle part of the housing can be provided by any other type of linear guide elements, e.g. they can be connected by rails.
• the assembly of the loading compartment cover advantageously also includes a panel for the loading compartment side walls, whereby the guide strips are part of the panel.
• the guide strips can then be formed at the same time as the panel (e.g. pressing or injection molding process), so that production in principle, the cost is not increased, as they do not have to be installed separately on or under the cover, etc.
• the assembly can also be designed in such a way that it includes guide rails separate from the paneling, so that the assembly can also be installed in vehicles that are not adapted for this in any way from production.
• the side walls of the loading space and the guide rails can then be at a non-constant distance from each other, whereby the difference between the distance in the horizontal direction perpendicular to the longitudinal axis of the vehicle between the guide rails at their front end and their rear end is less than or equal to the sum of the sizes of the closed intervals of displacement of both guide elements relative to the strut body.
• the telescopic displacement of the guide elements thus makes it possible to at least compensate for the difference in the distance between the guide rails.
• the difference between the largest distance in the horizontal direction perpendicular to the longitudinal axis of the vehicle between the guide rails and the minimum distance in the same direction between the guide rails can be less than or equal to the sum of the sizes of the closed intervals of displacement of the two guides relative to the strut body.
