Description:
FIELD OF INVENTION 
       [0001]    The present invention relates to a baggage space cover system. 
       BACKGROUND 
       [0002]    Baggage space covers are used in vehicles, such as station wagons, for separating the baggage space compartment of a vehicle from the passenger compartment and to prevent from possibilities to view from the outside of the vehicle what is stored in the baggage space compartment. 
         [0003]    In a common type of baggage space cover the complete cover is stored in a cassette and can be pulled out from the cassette when in use and fastened to the side walls using any conventional means like hooks or snap-in solutions. Other types also exist not using a cassette for storing the cover when not in use but instead folding the cover. 
         [0004]    In a cassette type the cover is attached to a shaft and wound onto this shaft when stored in the cassette. The winding shaft often has some mechanical means, like a telescopic arrangement, for axial movement to allow the shaft to be compressed in axial direction, i.e. the length of the shaft can be varied. Each end of the cassette has end pieces comprising means for detachably mounting the baggage space cover to the opposing side walls of the baggage space compartment of the vehicle and for holding the shaft ends. The cassette for the baggage space cover is mounted to the opposing side surfaces of the baggage space compartment by pressing the end pieces into recesses integrated in the opposing side surfaces. When the end pieces are pressed into the recesses, the shaft will first be compressed and then expanded when the end piece reaches its rest position. When performing this operation of attaching the baggage space cover the operator has to stand behind the vehicle and bend into the baggage space compartment while at the same time applying a certain pressure to press the end piece into the recesses. This is experienced as uncomfortable and is an unsuitable working position. 
         [0005]      FIG. 1  shows a prior art solution for end pieces with the locking sliders  101  and  102  having a flat upper surface  103  and  104  and a leaf spring  105 . The coordinate symbol  107  is defining an X-direction  108  corresponding to the length direction of the vehicle and a Y-direction  109  corresponding to the lateral vehicle direction and a Z-direction  110  corresponding to the height direction of the vehicle. This definition of directions is used throughout the rest of the document.  FIG. 1  shows the locking sliders in an extended position extending through holes  111  and  112  in a recess arranged at the side surface  113  of the baggage space compartment, and thus locking the end pieces and the baggage space cover to the side surface. The leaf spring  105  is pressing the end piece upwards, in positive Z-direction, thus fixing the cassette in Z-direction. A drawback with this solution is that there are no special positioning means for the X and Y directions but the positioning in these directions are determined by the manufacturing tolerances of the vehicle and components. Another drawback is that the relatively stiff, metallic leaf spring might cause wearing of the surfaces in contact with the spring. Also for this prior art solution, the operation to attach the cassette results in an uncomfortable and unsuitable working position as a substantial pressure has to be applied to overcome the pressure of the leaf spring. 
         [0006]    The technical solutions described above are relatively complicated, requires moving parts which makes it expensive to manufacture and/or gives an inadequate positioning of the baggage space cover. Poor positioning of the baggage space cover results in a disturbing, rattling noise when the vehicle is in motion. 
         [0007]    There is thus a need for an improved solution allowing easier and more comfortable mounting of the baggage space cover unit, simpler mechanical design with better positioning resulting in elimination of or at least substantial reduction of disturbing noises. 
       SUMMARY 
       [0008]    It is therefore the object of the invention to provide a baggage space cover system comprising a pair of end pieces, mounted to each end of a cassette containing a baggage space cover, and corresponding recesses arranged at opposing side surfaces of the baggage space compartment of a vehicle. Each end piece is configured for mounting in a corresponding recess, each end piece comprising:
       at least one lock slider configured to lock the end piece to opposing side surfaces of the baggage space compartment of the vehicle   mechanical means connected to the at least one lock slider and configured to hold the at least one lock slider in locked position.   arrangement for the release of the at least one lock slider from locked position
 
which can solve the problems of uncomfortable mounting of the baggage space cover unit to the side surfaces of the baggage space compartment of the vehicle, complicated mechanical design and rattling noise when the vehicle is in motion.
       
 
         [0012]    This object is achieved by providing an end piece where a lower surface of the end piece and a bottom surface of the recess are provided with cooperating guiding means, wherein a first guiding means comprises at least one protruding ridge and a second guiding means comprises at least one groove for mating with said ridge, which guiding means extend substantially in at least one of the length and lateral direction of the vehicle, thus positioning the end piece in respectively lateral and length direction. 
         [0013]    The advantage with firmly positioning the end piece in length and/or lateral direction and the height direction of the vehicle is that the rattling noise is decreased. The curved profile of the upper surface of the locking sliders creates a downward pressure when the sliders are extended into the holes in the recesses arranged at the opposing side surfaces of the baggage space compartment. This downward pressure presses the protruding ridge or ridges into the corresponding groove or grooves and thus increases the stabilization of the end piece in length and/or lateral direction of the vehicle while at the same time stabilizing and positioning the end piece in the height direction of the vehicle. 
         [0014]    A further advantage is that the end piece design makes it easier to install the baggage space cover device in the vehicle. The end pieces are easily pushed into the recesses arranged at opposing side surfaces of the baggage space compartment as there is no spring force to overcome to get the end pieces into a locked position. 
         [0015]    An additional advantage with the curved profile of the locking sliders is that a self stabilizing positioning is obtained. Vibrations of the baggage space cover makes the locking sliders to be further extended into the holes in the recesses arranged at opposing side surfaces of the baggage space compartment and thus increasing the downward pressure and improving the stabilisation of the positioning. 
         [0016]    Further advantages are achieved if the invention also is given one or several of the characteristics of the independent claims such as:
       front and rear lock sliders   lateral lock slider   a combination of front, rear and lateral lock sliders   the upper surface of the at least one lock slider having a sloped surface   guiding means comprising protruding ridges and grooves of different shapes   orthogonal ridges to achieve positioning in two directions   separate end piece block comprising the guiding means   suitable material and surfaces for lower surface of the end piece and the bottom surface of the recess to achieve a high friction between these parts and thus achieving a positioning also in the lateral direction of the vehicle.   attachment of a spring to the mechanical means to force the at least one lock slider into extended locking position.

     DETAILED DESCRIPTION 
       [0033]    The invention will in the following be described in detail with reference to the drawings. 
         [0034]      FIG. 1  has already been described in relation to Background art above. 
         [0035]    A complete baggage space cover as mounted in a vehicle is shown in  FIG. 2 . A baggage space cover  202  is wound onto a winding shaft (not shown in the figure) with a fixed length which rests inside a cassette  201  when not in use. The baggage space cover  202  can be pulled out and fastened to the opposing side surfaces of the baggage space compartment using any conventional means like hooks or snap-in solution. In  FIG. 2  the opposing side surfaces comprises side trims  203  and  204  to facilitate the mounting of the baggage space cover. The side trims are detachably mounted to opposing side walls of the baggage space compartment. In other embodiments the opposing side surfaces can comprise solutions other than side trims or the opposing side surfaces can be the side walls of the baggage space compartment. The cassette has end pieces  205  and  206  at each end. The coordinate symbol  207  defines the directions as explained above in association with  FIG. 1 . 
         [0036]      FIG. 3  shows the cassette  301  with the end piece  302 . Each opposing side surface of the baggage space compartment has a recess for holding the end piece. In the embodiment of  FIG. 3  a recess  305  for holding the end piece  302  is accomplished in the side trim  303 . On top of the end piece is a release button  304  explained below. 
         [0037]      FIG. 4  is an exploded view of an embodiment of the end piece  401  with a front lock slider  402  and a rear lock slider  403 . A cog wheel  404  is mounted on a tongued flange  405  located between cogged planar areas  406  and  407  of the lock sliders. The cogs in the areas  406  and  407  fits into the cog wheel  404 . A hole  408  in the tongued flange  405  is designed to receive one end of the winding shaft. A spring  409  is arranged around the tongued flange  405  and drives the lock sliders to its extended lock positions. The release button  410  is connected to the rear lock slider  403  through a tab  411 . When the release button is pushed in front direction or positive X-direction according to coordinate symbol  412  the rear lock slider  403  follows by means of the connection with the tab  411 , turns the cog wheel  404  which activates the spring  409  and drives the front lock slider  402  to a position inside the end piece as long as the release button is pushed forward thus releasing the end piece. 
         [0038]      FIG. 5  is a cross section of an embodiment of the invention, having side trims as opposing side surfaces in the baggage space compartment, showing the end piece  501  and the side trim  502  with a protruding V-shaped ridge  503  on the bottom of the recess in the side trim. The end piece comprises the front lock slider  504 , the rear lock slider  505 , the cog wheel  506 , the release button  507  with the tab  508  as explained above. A lower surface  519  of the end piece has a V-block  509  integrated with the end piece or as a separate component mounted flush to the bottom of the end piece with any conventional means like gluing, welding or snapping. A V-shaped groove  518  of the V-block mates with the corresponding V-shaped ridge  503  on a bottom surface  520  in the recess  511  of the side trim, thus positioning the end piece and baggage space cover in the X-direction, corresponding to the length direction of the vehicle, see coordinate symbol  510 . When the end piece is pushed down in the recess  511  of the side trim, the rear and front lock sliders are snapped into holes  512  and  513  of the side trim. The V-shaped ridge  503  and the V-shaped groove  518  are thus used as guiding means for the positioning. The spring  409  is not shown in this figure for clarity reasons. 
         [0039]    As the spring  409  pushes the sliders apart from one another they will be pushed into the holes  512  and  513  in the side trims and hit the side trim at contact points  514  and  515 . Due to the sloped shape of surfaces  516  and  517  of the lock sliders they will push the end piece down, in negative Z-direction, pressing the V-block into the V-shaped ridge of the side trim, thus completely locking the end piece to the side trim also in Z-direction, corresponding to the height direction of the vehicle. 
         [0040]    In an embodiment of the invention each end piece comprises of just one lateral lock slider and in yet another embodiment of a combination of a lateral, a front and a rear lock slider. 
         [0041]      FIG. 6  shows different arrangements to achieve the positioning by using a ridge and a mating groove as guiding means for positioning.  FIG. 6   a  shows the arrangement according to the embodiment described in  FIG. 5  above with a ridge  601  on the side trim, or other arrangements for the opposing side surfaces to the baggage space compartment, recess bottom surface  602  and the groove  603  in the end piece lower surface  604 . The shaded bottom part of the end piece can be designed as a separate block  605  which is mounted flush to the bottom of the end piece with any conventional means like gluing, welding or snapping.  FIGS. 6   b - e  illustrates other possible shapes of the groove on the lower surface of the end piece.  FIGS. 6   f-j  illustrates other embodiments of the invention where ridges of different shapes are integrated in the lower surface of the end piece and the mating groove is made in the bottom surface of the recess in the side trim or other arrangements for the opposing side surfaces to the baggage space compartment. 
         [0042]      FIG. 7  illustrates an embodiment with two orthogonal ridges  702  and  703  as guiding means on a surface  701  which can be either the lower surface of the end piece or the bottom surface of the recess to the side trim. 
         [0043]    The ridge  702  in Y-direction, see coordinate symbol  704 , locks the end piece in X-direction, which corresponds to the length direction of the vehicle, while the ridge  703  in X-direction locks the end piece in Y-direction, corresponding to the lateral direction of the vehicle. 
         [0044]    Due to manufacturing tolerances there will be a possibility for movement a few millimetres in the Y-direction. This can be avoided by implementing the ridge  703  as described above and/or by a suitable choice of material and surface texture for the lower surface  519 ,  604  of the end piece and the bottom surface  520 ,  602  of the recess. In an embodiment the lower surface  519 ,  604  of the end piece is made e.g. of plastic or synthetic rubber with a suitable shore value having a rubber like texture and creating a high friction towards the bottom surface  520 ,  602  of the recess  305 ,  511  made of e.g. suitable plastics like ABS, PP or PC/ABS and in one embodiment having an engraved bar pattern. The high friction between these surfaces in combination with the weight of the baggage space cover device including the cassette with end pieces, winding shaft and cover, makes a movement in Y-direction unlikely unless there are severe side forces due to sudden movements of the vehicle.
